Free Will and Fate free essay sample

Everything in life happens for a reason, may it be the choices made or the destiny fulfilled. Along the way though many people offer advice that affect choices made, was it fate that they gave their input? Is it free will to take or not to take that advice? Homer’s epic poem, The Odyssey demonstrates that despite warning, characters often use their free will to make choices that in the end actually fulfill their fate. Primarily Aegisthus’s refusal to acknowledge the gods warning, serves as the first example of mankind using her own free will to bring her destiny to fruition. Hermes tells Aegisthus not to sleep with Clytemnestra and not to kill Agamemnon, but he does so anyway, and so Orestes kills Aegisthus as revenge. Aegisthus received warning from the gods, they told him â€Å"far in advance†¦Ã¢â‚¬â„¢don’t murder the man†¦ don’t court his wife†¦ revenge will come from Orestes’† (Homer 1. We will write a custom essay sample on Free Will and Fate or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 45-48) and the predicted outcome came true –Aegisthus was killed. The Gods warned Aegisthus of what his fate held, and in utilizing his free will he chose to ignore this advice and his fate became reality. It is â€Å"with [each characters] own reckless ways heir pains [are compounded] beyond their proper share† (Homer 1. 39-40); meaning that committing reckless actions will result in possible calamitous outcomes. Aegisthus chose to kill Agamemnon, he chose to court Clytemnestra, he chose to ignore the advice from the gods, and so he ended up destroyed fulfilling the fate of receiving pain thanks to his own reckless behavior. Likewise, Homer clearly comments on the tendency of humans disregarding warnings of potential hazards, through his inclusion of The Phaecians’ decision to ignore their prophecy and aid travelers resulting in fate fulfillment. The Phaecians’ were forewarned in a prophecy that â€Å"Poseidon was vexed with [them] because/ [they] escorted all mankind and never came to grief / [and]†¦ one day a well built ship of [theirs]†¦ [would be crushed]† (Homer 13. 196-200); Alcinous’s father received this prophecy years ago and gave no acknowledgement of the prophecy when time came to ship Odysseus back to Ithaca. As a result of The Phaecians’ seeing blind of the prophecy and escorting Odysseus back to Ithaca, their ship got crushed and mountains surrounded the port. When Odysseus determined that it was time for him to sail back to Ithaca, Alcinous had no hesitation in assisting him. Alcinous â€Å"knew [that Odysseus] wouldn’t be driven /off†¦course, [that] nothing could hold [him] back† (Homer 13. 5-7), but what he knew and ignored was the free will choice he made to neglect the prophecy and allow the fate of himself and his fellow Phaecians to end in destruction just as it was destined to be. Similarly, Amphinomus reflects the human quality of free will leading to fate as he acquired purposeful advice from Odysseus (the beggar), yet he continued his pursuit of Penelope, and ended up dead. Amphinomus received potentially life saving advice from the one that ended up killing him, Odysseus, but his ignorance of the ‘vagabond’ and how insightful he was made him assume that he would â€Å"never suffer affliction down the years†¦ affronting the loyal wife of a man who won’t be gone†¦long† (Homer 18. 153-168) and so in the spirit of free will he continued to attempt to court Penelope all under the nose of Odysseus. Therefore, as Odysseus began his revenge Amphinomus was â€Å"fraught with grave forebodings†¦. /but not even so could he escape his fate†¦ Athena had bound him fast to death /at the hands of Prince Telemachus and his spear† (Homer 18. 77-179) as it had been destined to be. Cause: Amphinomus ignoring advice given to him that would potentially save his life Free Will†¦ Effect: Amphinomus is killed Fate. All in all, Homer’s The Odyssey display’s the idea that regardless of warning fate is decided by free will and vice versa. Aegisthus, The Phaecians, and Amphinomus all received warning, and utilizing their free will they all chose to take a separate path one that led to ultimate fate. ‘Fate leads him who follows it, and drags him who resists. ’

History or Japanese textiles essays

History or Japanese textiles essays The oldest extant Japanese textiles date from the Nara Period (710-785AD) and impressions of cords have been found on earthenware pots from the Jomon period of Japanese History (10,000-300 BC). Apart from these examples, very little is known of Japanese textiles prior to the 8th Century. However, Japanese textiles were strongly influenced by Chinese and Korean textiles from their inception and we can follow the evolution of Japanese textiles by studying the history of early Chinese and Korean textiles. The textile industry in China and Korea dates back to around 5000BC with woven textiles found in archaeological sites from this period. The raising of silk worms in captivity (sericulture) became widespread around 4000BC. The traditional use of textiles in these countries was for clothing, furnishings and ceremonial purposes such as alter clothes and ceremonial robes. The main fibres used for textiles in the China/Korea region were hemp, ramie, cotton and silk. The Chinese followed strict codes of dress according to classes and introduced strict sumptuary laws to enforce these codes. These laws dictated what fabrics, colours and designs should be worn by different classes of people. Royalty wore mostly silk and clothes decorated with embroidery. Commoners wore hemp, ramie and course cotton clothing. Tapestry, the use of weft threads that do not extend across the entire width of a piece of fabric but individual colours used in discrete areas, was introduced during the Sang Dynasty (960-1279 AD). Japanese textiles throughout the ages The oldest textiles in Japan can be found in a collection at the Shoshoin Temple in Nara, the ancient capital of Japan, near modern day Kyoto. These probably come from China and Korea because they were produced on a draw loom and it is not believed that the Japanese wove used draw looms in the 8th Century. Among this collection of textiles can be found Nishiki which is a textile with a ...

W 9 Chemicals and Pests- Discussion- environmental - Essay Example As for ants, we either flush them away with cold water or we wipe the ants up in a damp rug and rinse the rug in order to wash the ants down the drain. Since my mom has been growing a small pocket garden in the front of our house for a number of years now, I do not really mind the use of fertilizers in gardens and lawns since it helps to ensure a good plant growth. However, my mother uses organic fertilizers for this purpose and not chemically treated fertilizers. The only chemical that she uses on her plants is something called Malathion which, I have to admit, has a rather offensive smell once it is sprayed on the plants. I believe that fertilizers are a necessary evil in the development and aesthetic development of plant growth. Does its aesthetic benefits outweigh the negative effects? I would have to say that it does not because it directly affects my health. However, these negative effects only come into play when using artificial fertilizers. The same does not apply when using organic

Discuss the weaving together od induction and deduction with imperical evidence in the scientific method. - talk about the scientific method, then use examples to - Essay Example The products included an expanded body of knowledge, tools and techniques† (The dawn of Science, p.26). The nature itself was the tutor for the ancient human being. He has learned many things from the nature by observations, testing and analysis. He has devised many methodologies and formulated many concepts based on his experiences with the interaction of nature. Though he was unaware of many natural phenomena at that time, his interaction with nature has made him aware the common patterns associated with all the nature’s activities such as day and night and summer and winter. The scientific method has emerged through these careful observations and analysis of nature’s activities. General principle and scientific principle have lot of differences. General principle may not have any scientific evidences. For example sun is believed to be rises in the east. But east, west, north, south concepts are relative and all such things are mere assumptions and have no Scientific method of inquiry usually associated with gathering observable, empirical and measurable evidence subject to specific principles of reasoning. Scientific method consists of the collection of data through observation and experimentation. These data will be used to formulate hypothesizes. From these hypothesizes, conclusions will be made. Scientific method is the method adopted by scientists in their investigation of various phenomena. It is a systematic and orderly method of solving problems. Whatever be the nature of the problems, the scientists adopt a cautious and methodical procedure that helps him to acquire valid and verifiable conclusions. Sensing of the problem is the first step in scientific method followed by the research. The research will provide lot of data which will be used for generating various hypothesizes. These hypothesizes will be tested and then the conclusion will be made which will lead to the formulation of laws. Such formulated laws

Challenge Workplace Diversity Essay Example for Free

Challenge Workplace Diversity Essay As with anything that requires a change in established attitudes and behavior, achieving true diversity in the workplace can be a challenge. The challenges of diversity in the workplace are often the result of a combination of different factors, but resistance to change on the part of both employees and employers continues to be the primary underlying issue. One of the challenge workplace diversity is communication. This is because an organization trying to adopt a more inclusive environment is assimilation for any member outside of the dominant group. Without proper communication, barriers that exist between groups of people due to actual or perceived differences and pre-conceived notions cannot be effectively broken down. The purpose of diversity training in the workplace, among other things, is to improve communications between diverse social groups. Besides that ,the challenge is refer to diversity management. Related to the challenge of policy implementation, diversity management must be properly delegated and enforced in order to be effective. If no one person or department is in charge of enforcement and implementation of any type of policy, it goes without saying that the policy will most likely not be effectively followed or enforced. Diverstiy management also want to face many problem when their worker giving different opinions and should find the good solution to solve from different etnic. Managing diversity is more than simply acknowledging differences in people. This is an additional challenge that diverse organizations face, maintaining a culture which supports the idea of employee voice especially for marginalized group members. When the organizational environment is not supportive of dissenting viewpoints, employees may choose to remain silent for fear of repercussions or they may seek alternative safe avenues to express their concerns and frustrations such as on-line forums and affinity group meetings. By finding opportunities such as these to express dissent, individuals can begin to gather collective support and generate collective sense-making which creates a voice for the marginalized members so they can have a collective voice to trigger change.

The Basic Theory Of The Arbitrage Pricing Theory Finance Essay

The Basic Theory Of The Arbitrage Pricing Theory Finance Essay The Arbitrage Pricing Theory is an asset pricing theory that is derived from a factor model, using diversification and arbitrage arguments. The theory describes the relationship between expected returns on securities, given that there are no opportunities to create wealth through risk-free arbitrage investments. APT is one of the most influential theories in the stock pricing which is initiated by the economist Stephen Ross in 1976. It predicts there is a linear relationship between expected return and risk which can be linked by SML. APT suggests that the assets return to investors could be influenced by many independent macro-economic variables. It does not require the existence of true market portfolio and demand less restrictive assumptions compare the other asset pricing model such as the CAPM. Arbitrage arises if an investor can construct a zero investment portfolio with a sure profit. APT relies on three propositions: (i) the security returns can be described by a factor model (ii) idiosyncratic risk can be diversified away (iii) arbitrage opportunities are eventually diversified away. Since no investment is required, investors can create large position to secure large level of profit. However, profitable arbitrage opportunities disappear in efficient markets. The APT formula is as following: E(Ri) = Rf + b1*(E(R1) Rf) + b2*(E(R2) Rf) + K+ bn*(E(Rn) Rf) Rf = Risk free interest rate bi = Sensitivity of the asset to factor i E(Ri) Rf) = Risk premium associated with factor i where i = 1, 2,n Multi-factor model and many relevant researches to basic financial factor has developed since Ross (1976) raised the arbitrage pricing theory, such as the three factor model of Fama and French (1993). Fama and French (1993) continues the research method of Fama and Macbeth (1993)Aand conclude that the APT has explain better the return of the stock than the CAPM . Fama and French (1996) argue that the CAPM does not explain the patterns such as size, book-to-market equity, earnings/price etc. in average return on common stock. And these anomalies are captured by the three factor model of Fama and French (1993). The three factor model is as following which indicates that the three factors, (Rm ? Rf), SMB and HML are used to explain the returns of stocks : SMB = Small Minus Big; returns on small stocks in excess of returns on large stocks HML = High Minus Low; returns of stocks with high BTM ratio in excess of returns on low book-to-market ratio According to the equation above, Fama and French (1993) states that the pattern in the HML slopes does not predict the continuation but the reversal for future returns. Therefore, the continuation of short-term returns documented by Jegadeesh and Titman (1993) is left unexplained by the three Vfactor model (Fama and French). The three-factor model in the above equation captures much of the cross-sectional variation in average stock with the reversal of long term returns documented by DeBondt and Thaler. The results of the empirical tests were taken by Fama French]1996^are consistent with APT asset pricing. Fama and French argue that it is an equilibrium pricing model, a three-factor version of APT (Ross 1976) due to the empirical successes. Fama and French (1996) conclude that the three-factor model is a good model although it does not explain the expected return on all securities and portfolios. But it captures the anomalies on the portfolios formed on size and book Vto market equity, earnings/price etc. On the other hand, Roll and Ross (1995) conclude that The APT approach to the portfolio strategy decision involves choosing the desirable degree exposure to the fundamental economic risks that influence both asset returns and organizations. Roll and Ross (1995) states that APT can be adapted to special situation comparing to many traditional approaches because of its flexibility and it will be well-suited to the management of huge amount of funds. Later on, Chen, Roll and Ross (1986) examined the validity of the APT in the US stock markets. The test is based on the APT and suggests the multi-factor model .Chen, Roll and Ross (1986) found that the set of macroeconomic variables including: industrial production, changes in the risk premium, twists in the yield curve etc. are found to be significant in explaining the expected stock returns. The result of their research is consistent with the APT (Ross 1976) which implies that APT is valid. They believe that the multi-factor of APT captu res more risk factors and explains better of the asset returns, therefore, it is more useful than the CAPM. In conclusion, Arbitrage pricing theory (APT) is a valuation model as it does not required the existence of true market portfolio and fewer assumption is used which is more rational comparing to the CAPM. APT relates the individual asset price to the variety of unanticipated events driving it rather than rely on the measuring of the market performance. Beenstock and Chan (1986) found that the multi-factor APT has a better explanation than the single factor CAPM in the UK stock market through the Non-Nested Test. Also, Fama and French (1996), Chen, Roll and Ross (1986) have consistent results with the APT and therefore support APT over CAPM. However, there still many ambiguities hide in the model. Shanken (1982) challenge to testability of the APT as theory has been silent about which economic state variables are likely to influence all assets and there is a complete ignorance to the identity of the relevant factors that explains different returns. Also, the economic variables are not yet determined that which are responsible to the asset prices. Reinganum (1981) found that his results are inconsistent with the APT and according to the Roll and Rosss study, they conclude that although the evidence generally support the APT, acknowledged that their empirical tests were inconclusive. Therefore, due to the complexity of and dubiosities of the APT, companies choose to apply the CAPM instead. In view of this, more researches and improvements should be made to the APT in order to increase the usefulness of it.

Bell LaPadula

In recent years, the Bell-LaPadula model has been employed more and more in scientific Since publication, the Bell-LaPadula model has helped in the advancement of science and technology by providing a mathematical basis for the examination of laboratory security. Moreover, this model is a major component of having a disciplined approach to building secure and effective laboratory systems.The Bell-LaPadula model can also be used to abstractly describe the computer security system in the laboratory, without regard to the system's application.The goal of modern security research is to facilitate the construction of multilevel secure systems, which can protect information of differing classification from users that have varying levels of clearance. There are some deficiencies inherent in the Bell and LaPadula model, and there have been efforts to develop a new approach to defining laboratory security models, on the basis that security models should be derived from specific applications. Project Aims and Objectives:The objective of this research is to ascertain the ways in which the bell-lapadula model can be applied to Laboratory Information Management Systems. Laboratory automation occurs when the application of technology is used to reduce the need for human intervention in the laboratory. This makes it possible for scientists to explore data rates that otherwise may be too fast or too slow for proper scientific examination. Moreover, the research was also aimed to investigate the possible practical applications of the Bell-Lapadula model in library information management systems (LIMS).The main intention of this modern security research is to facilitate the construction of multilevel security systems, which can protect information of differing classification from users that have varying levels of clearance. Since publication, the Bell-LaPadula model has helped in the advancement of science and technology by providing a mathematical basis for the examination of l aboratory security. Moreover, this model has been major component of having a disciplined approach to the building of effective and secure laboratory systems.Project Outline: Literature Survey: The use of the Bell and LaPadula Model has been successful in modeling information that is relevant to security, even though this success might be responsible for the vagueness of the model about its primitives. This vagueness can also be examined with respect to the theory that the Bell and LaPadula Model and Noninterference are equivalent. Laboratory automation makes it possible for scientists to explore data rates that otherwise may be too fast or too slow to properly examine.Therefore, an automated laboratory reduces the need for human intervention and creates a more efficient environment in which human beings and technology can interact to produce a great deal more information and accurate data that was not possible prior to automation. Its approach is to define a set of system constrain ts whose enforcement will prevent any application program executed on the system from compromising system security.The model includes subjects, which represent active entities in a system (such as active processes), and objects, which represent passive entities (such as files and inactive processes). Both subjects and objects have security levels, and the constraints on the system take the form of axioms that control the kinds of access subjects may have to objects. (http://chacs. nrl. navy. mil/publications/CHACS/2001/2001landwehr-ACSAC. pdf)While the complete formal statement of the Bell-LaPadula model is quite complex, the model can be briefly summarized by these two axioms stated below: (a) The simple security rule, which states that a subject cannot read information for which it is not cleared (i. e. no read up) (b) The property that states that a subject cannot move information from an object with a higher security classification to an object with a lower classification (i. e. no write down). (http://chacs. nrl. navy. mil/publications/CHACS/2001/2001landwehr-ACSAC. pdf)These axioms are meant to be implemented by restriction of access rights that users or processes can have to certain objects like devices and files. The concept of trusted subjects is a less frequently described part of the Bell-LaPadula model. Systems that enforce the axioms of the original Bell-LaPadula model very strictly are often impractical, because in a real system, a user might need to invoke operations that would require subjects to violate the property, even though they do not go against our basic intuitive concept of laboratory security.For instance, there might be need in the laboratory to extract an UNCLASSIFIED paragraph from a CONFIDENTIAL document for use in a document that is UNCLASSIFIED. A system that strictly enforces the properties of the original Bell-LaPadula model might prohibit this kind of operation. As a result, a class of trusted subjects has had to be included in the Bell-LaPadula model, and is trusted not to violate security, although they might violate the property.Laboratory systems that are based on this less restrictive model usually have mechanisms that permit some of the operations that the property would normally not allow. It should also be noted that a number of projects have used the Bell-LaPadula model for description of their security requirements, although strict enforcement of the Bell-LaPadula axioms without the implementation of trusted subjects turns out to be overly restrictive in these projects. Thus, there has been widespread introduction of these trusted processes to implement the concept of trusted subjects.There are also some limitations involved in the use of the Bell-LaPadula model, including an absence of policies for changing user access rights. With this model, there can be secure and complete general downgrade, and is it is intended for systems that have static security levels. The Bell-Lapadula model would b e a suitable idea for Laboratory Information Management Systems because the model focuses on data confidentiality and access to classified information, in contrast to some other models that describe rules for data protection and integrity.Clear and concise access rules for clinical information systems spells out by this model. Furthermore, it reflects current best clinical practice, and it’s informed by the actual threats to privacy, its objective is to the maximum number of records accessed by any user, and at the same time the number of users who can access any record and this has to do with controlling information flows across rather than down and at the same time a strong notification property should be enforced.I will also discuss its relationship with other existing security policy models available, and the possibility of its usage in other applications where information exposure must be localized, which ranges from private banking to the management of intelligence data , and much more. Another area in which laboratories could benefit by using the Bell-Lapadula model is the multi million dollar drug industry, which requires a high level of security and confidentiality since drug research sensitive, and results or findings in an ongoing research may sometimes need to be kept from unauthorized persons.Description of the Deliverables: This research will be conducted by investigating the possible practical applications of the Bell-Lapadula model. This would be conducted and tested physically and objectively. A prototype will be built in order for it to be properly tested, since it is practical. The testing stage will involve programming codes for different levels of security and the objective is to find out if security can be breached at any stage. Evaluation Criteria Evaluation of the involve the Resource Plan:The equipment, software, and other materials necessary to complete the project, how they are to be provided, and what the financial costs will be, such as travel. Project Plan and Timing: Anticipated milestones and interim deliverables. A detailed timetable (schedule) of the stages, including the estimated finishing date, is a must. Stages will be reviewed with the sponsor and Dissertation Advisor. Don’t simply list the stages of the project and their timetables, but supply information what is done in each of them with special emphasis on the last stage of the project.Risk Assessment: A description of what obstacles may arise and contingency plans to meet them. One aspect that should be considered here is the availability of the software and hardware you intend to use and, if you need to interface several pieces of software, whether this is known to be possible. Quality Assurance: How progress on your project will be monitored and how success at each stage will be assessed. This may include, but should not be limited to, the formal project assessments.

Economic and Environmental benefits of Green walls

IntroductionGreen wall and its necessityThe life, organic systems characterized by green walls, are integrated with the inorganic and exanimate constructions are ruling modern architecture and holds the promise of a new type of ‘living ‘ architecture. Green walls are by and large walls that are portion of the Building covered with flora. They are similar perpendicular garden largely formed with creeper system on the exterior wall with the roots on the land or with free standing vertically framed wall with different native workss grown on the surface. They are besides termed as bio walls or populating walls since they act as natural air-conditioner as they purifies and cools the ambient air to a big extent making a healthy environment. The deepest menace of planetary heating is the rapid urbanisation and deforestation. There is a considerable addition of co2 emanation and heat transportation. This impact is utmost in the urban status where the vegetation/ verdure are sparse. Besides in the urban conditions largely all the edifices are glazed and air-conditioned with out any ways of neither thermic insularity, nor are they shaded with thick environing landscape. This is fundamentally due to the infinite restraints and optimisation. In such ambitious instances Green wall is the best option which acts as a good shading device against heat addition and energy losingss, pollution etc. Hence, Green walls are must in urban conditions.Economic and Environmental benefits of Green wallsThe economic and environmental benefits are many. They result in significant energy nest eggs, extension of constructing life, CO2 gaining control, acoustics and Aestheticss.Energy Conservation: Vegetation on walls can help in chilling edifice s in summer and insulating them in winter. Decrease of thermic lading to edifices consequences lower warming and chilling costs which in bend lowers carbon emanations. Jacklyn Johnston and John Newton ( 2004 )Health: These mounting workss on green walls filter out dust and other pollutants. Jacklyn Johnston and John Newton ( 2004 )Decrease of heat island consequence consequences in less reflected heat.Air purification: workss filter pollution particularly when used inside edifices.Noise fading: It acts as sound barrier ensuing in quieter edifices and streets.Green walls can roll up over 30kgs per M2 of rainwater.Increased urban biomass.Jacklyn Johnston and John Newton ( 2004 ) clears the fact that ‘There is a widespread belief that workss are unfriendly to construct constructions, rending out howitzer and prying isolated articulations with their roots. The grounds suggests that these jobs have been greatly overdone, except where decay has already set in and so workss can so sp eed up the procedure of impairment. ‘ There is small grounds that workss damage walls. In fact in most of the instances the exact opposite is true, with workss covering the wall helps in protecting the wall from harmful elements, solar radiation which in bend reduces the thermal tensenesss within the construction.Autochthonal sustainable elements and their benefitsAutochthonal sustainable elements are the simple elements which are locally available and considered as waste or least prioritized. For illustration, the coconut shells in the state like India which are available in copiousness are merely disposed or burnt to ashes even though they have high thermic coefficient and suitableness for insulation/ acoustics. Similarly, stuffs like Clay, Bamboo, Jungle/ Pine/Rubber wood, Cork etc carry untarnishing consequence in the field of sustainable Architecture when used suitably. Apart from their interesting feature they are besides economic.RESEARCH QUESTION/OBJECTIVE:Department o f energies green palisade demand to be green?The realistic aim of this research is to make more gratifying greener metropoliss which in bend bring legion benefits to the environing environment. In the about all the Urban locations of the universe where the CO2 emanation is highly high due to assorted factors have barely any good flora to command environmental pollution. Unfortunately, in such locations the construct of sustainability like ‘Green wall ‘ gets relegated to the 2nd topographic point due to building and care cost. The thought is to turn to to these countries and besides to heighten the benefits of â€Å" Green walls ‘ with some medicative value. This needs to be achieved by placing native herbal workss and besides, to analyze and introduce in the country of low cost autochthonal elements like coconut shells, bamboo, cane, Jute, cork, ect as building stuffs to supplement to sustainable design.LITERATURE REVIEW:Green walls are easy deriving value and are considered valuable for chilling the Urban infinite than green roofs in states like Japan. But the green wall is still new to states like India and China. Jacklyn Johnston and John Newton ( 2004 ) states that ‘This is a great commiseration, because even in those metropoliss comparatively good endowed with greenspace many countries can justifiably be regarded as comeuppances in biological footings. ‘ Nigel Dunnett and Noel Kingsbury ( 2004 ) Green wall is widely practiced in Europe and it is rather common in France and Germany to see house covered in Virginia creeper or vines which are influenced by Mediterranean clime. Jacklyn Johnston and John Newton ( 2004 ) states that ‘We necessitate appropriate development which incorporates an ecological attack to edifice and landscape. ‘ This means that the land lost in the building of edifices and roads should be replaced with a bed of workss on the difficult surfaces. By this manner green tegument can be strategical ly added to make a new web of flora associating roofs, courtyards, walls and unfastened infinites.Different types of green wallsThere are two different types: Green frontages and Living wallsGreen facades: are wall systems where workss cover back uping constructions rooted at the base of the construction. Supporting construction can either be a bing wall or built as freestanding constructions. Populating walls: ( besides called bio walls or perpendicular gardens ) composed of pre-vegetated modular panels that are fixed to a structural wall or freestanding frame. Modular panels comprises of polypropene plastic containers, geotextiles, irrigation system, turning medium and flora. Populating walls can be installed on the outside of a edifice in full Sun, shadiness, and inside of a edifice. They grow good in both tropical and temperate clime. Due to immense assortment of workss used, populating walls require more intensive care than green frontages like regular lacrimation, adding foods and fertilisers.Different types of green facade support constructionsThe two primary types areModular treillage systems: Panels which are stiff and lightweight are installed vertically as wall-mounted or freestanding. They can besides be used on tall edifices along side with intermediate plantation owners. Modular treillage systems are indispensable where the physical growing of mounting workss is restricted.Freestanding constructions: are stiff panels such as green columns or canopy signifiers that can be placed on either on edifice walls where either the infinite is limited or burden is restricted. The panels can besides be used as shading devices for a unfastened parking country.Cable and rope wire systems: this system consist high-tensile steel overseas telegrams, wire treillages, spacers, and extra equipment. Vertical and horizontal wires are connected through cross clinchs to organize a treillage system of coveted sizes and forms. Stainless steel wire-rope cyberspace is supported on flexible or stiff frames to cover big countries.Best works types to utilize for green wallsJacklyn Johnston and John Newton ( 2004 ) Sing the relationship between the types of works used and the facet of the walls where they will turn is besides a really of import facet. Deciduous workss are the most suited on the south side of a edifice. In the summer their dense leaf shields the edifice from sunshine and creates chilling consequence. In winter foliages are shed, leting sunshine to make the surface of the wall so assisting to warm the inside of the edifice. Similarly on a west-facing wall it is reasonable to utilize evergreens to protect the edifice from rain and supply a shock absorber of air to assist insularity. North confronting walls are best for back uping native herbs and wider scopes of workss. East walls may fall into either class. Plants used on exterior edifice walls are exposed to harsher climactic milieus than those of indoors. Hence for edifice that intend to make great highs, more stalwart species of workss should be selected. Similarly, for less works friendly climes, climbers that are tolerant for air current and heat should be selected. Nigel Dunnett and Noel Kingsbury ( 2004 ) On wooden walls and other constructions, species with really heavy growing or a thick ramification wont should be avoided, as the construction may non be able to back up the weight. Plant choice will hold major impact on the design of the back uping system. For case, a denser and faster turning works will necessitate a larger infinite between supports than less aggressive works species. The denseness of works life further impacts the implicit in construction. Greater the leaf surface country, the more impact rain will hold on the weight of the system.Green wall installing and careJacklyn Johnston and John Newton ( 2004 ) Small herbaceous species are able to turn on walls by taking root in the substance of the wall itself. But other species are of course adapted to mounting up and over obstructions such as stone faces, trees and bush. Some sort of support construction is indispensable for these workss to turn successfully. For illustration, climbers such as hops support themselves by gyrating upwards around an object. They will necessitate lumber battings, trellis work, steel overseas telegrams or plastic ropes. Although some creeper can cleave straight onto wall s by their roots, they require a unsmooth surface to enable them to make so. Ramble oning workss such as bramble and mounting rose need wide-meshed grid constructions to which they can be attached. A 50x50cm fretwork of treated lumber mounted on wooden stations ( or an tantamount construction utilizing overseas telegrams, rope or sacking ) will supply an equal support for a scope of species. Whenever possible it is reasonable to go forth small spread between the facade of the edifice and the supporting construction to maximize the effects of summer chilling and winter insularity. The constructions help in administering the weight of the workss across the supporting construction and wall. In overseas telegram and rope wire systems, ground tackles and turnbuckles have to be installed at the terminal of each overseas telegram for fastening and accommodations as and when required. Jacklyn Johnston and John Newton ( 2004 ) Polypropylene cladding tiles incorporates rainproof membranes and their ain irrigation system. Plants could be established on these and so hung on the exterior of a edifice. Depending on species, mounting workss by and large require a good supply of H2O and occasional pruning. Supporting constructions require less care, with lone occasional monitoring of the supporting construction. Jacklyn Johnston and John Newton ( 2004 ) For mounting workss the land should be prepared merely like for any tree or bush by making a cavity and adding in some compost to the top 30cm.Pre-grown panels for populating walls needs 6-12 months for workss to turn prior to bringing and installing. The panels are grown horizontally until it is shipped to the site after which it can be mounted vertically. Climbing workss should be selected that do non supply a nutrient beginning for unwanted plagues and insects. Excessive growing or dead wood should be removed sporadically and standing H2O should be avoided.LEED points for utilizing green wallsLEED has several credits for green walls when used in edifices.Sustainable Sites Credit 7.1: Landscape Design that Reduces Urban Heat Islands ( 1 point ) .

The building industry in India happens to be one of the largest economic activities. As this sector is turning quickly, continuing the environment poses batch of challenges and at the same clip nowadayss chances. The building sector hence needs to lend towards environmental duty. Green wall constructs are at emerging phase in India chiefly due to high initial cost and deficiency of a native merchandise to turn to the same. But still it offers great potency which asks for greater apprehension and germinating an autochthonal merchandise by Indian Architects/ Landscape interior decorators.How cost witting developed states are and how it is of import?Most of the developed states are focused on the engineering of future and the art of modern architecture plays critical function where the value of simple autochthonal elements gets neglected. In that instance, even in the name of modernisation most of the development states are besides acquiring inspired by the developed states. Cost effectual design ever carries value at the clip of crisis and recession. It besides speaks its untasted appeal as they are formed largely with natural elements.Invention:An Indian based Agriculturist who tried organic agriculture ‘elunkathir pannai ‘ with the protection of bio fencing created with the native herb teas and workss. The consequence proved to be amazing and achieved good output. The interesting secrete behind it is, all the air born plagues are filtered and killed by of course available herbal marauders. This inspires and even strengthens the construct of Green walls for the urban infinites besides. And that is one of my enterprise and portion of the research utilizing native herb teas to accomplish medicative benefits.Sustainability is mostly being practised in assorted Fieldss. But in most of the instances they are non cost effectual.

Lab Report- Neurophysiology of Nerve Impulses Essays

Lab Report- Neurophysiology of Nerve Impulses Essays Lab Report- Neurophysiology of Nerve Impulses Paper Lab Report- Neurophysiology of Nerve Impulses Paper Neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons. One extension is different from all the others, and is called the axon. Although in some neurons, it is hard to distinguish from the entries, in others it is easily distinguished by its length. The purpose of the axon is to transmit an electro-chemical signal to other neurons, sometimes over a considerable distance. Longer axons are usually covered with a myelin sheath, a series of fatty cells which have wrapped around an axon many times. They serve a similar function as the insulation around electrical wire. At the very end of the axon is the axon ending. It is there that the electro-chemical signal that has traveled the length of the axon is converted into a chemical message that travels to the next neuron. (Dry. C. George Before, 2009). Axons are what make up nerves. A nerve is a bundle of neurons fibers or processes wrapped in connective tissue that extends to and/or from the CONS and visceral organs or structures of the body periphery (Marine Mitchell, 2009). In this experiment we will work with a nerve The action potential we will see on this experiment reflects the cumulative action potentials of all the neurons in the nerve, called a compound nerve action potential. Although an action potential follows the all-or none law within a single neuron, it does not necessarily follows the all-or-none law within an entire nerve. When you electrically stimulate a nerve at a given voltage, the stimulus may result in deportation of most of the neurons but not necessarily all of them. To achieve deportation of all of the neurons, a higher stimulus voltage may be needed ( Marine Mitchell, 2009). Seaplanes in the body all begin with the resting membrane potential. This is the natural state of a nerve before it is presented with a stimulus (Martini, Nathan Bartholomew, 2012). Resting membrane potential is important because it is necessary in order for a synapse to occur (Marine Mitchell, 2009). This resting Tate stands at -map because of three factors. First the ionic composition of the extracurricular and intracellular fluid varies in their charge. The Extracurricular fluid has a negative charge because of the An+ ion that exist, just as the intracellular fluid has a negative charge because of K+ ions and negatively charged proteins (Martini, Nathan Bartholomew, 2012). Second the cells have an uneven distribution because of the existence of sodium and potassium leak channels. This allows the creation of an electrochemical gradient, which ultimately is the force that guides the conduction of an action potential. The electrochemical gradient is created by sodium-potassium pump which is responsible for exchanging 3 An+ ions out while bringing in 2 K+ ions (Martini, Nathan Bartholomew, 2012). Third, the resting membrane potential varies in permeability based on the type of ion. Membranes are more easily permeable by K+ ions because of their size, which is responsible for the negative charge during the resting state (Martini, Nathan Bartholomew, 2012) Without a resting potential, we would not have a threshold to conduct an action potential. When a stimulus is presented, it requires a certain excitability, or popularization level of at least map to map (Martini, Nathan Bartholomew, 2012). The action potential depends on the threshold stimulus because of the all or none principle. This states that if a stimulus does not break the required threshold level, no action potential will occur (Martini, Nathan Bartholomew, 2012). However, if a threshold does uphold this principle, an action potential is created and a synapse begins. When membrane is exposed to a certain chemical, its response is either excited or inhibited. When a membrane is excited deportation begins. When the membrane depilatories the resting membrane potential of -70 NV becomes less negative. When the membrane potential reaches 0 NV, indicating there is no charge difference across the membrane. The sodium ion channels start to close and potassium ion channels open. By the time the sodium ion channels finally close. The membrane potential has reached +35 NV. The opening of the potassium channels allows K+ to flow out of the cell down its electrochemical gradient ( ion of like charge are repelled from each other). The flow of K+ out of the cell causes the membrane potential to move in a negative direction. This is preferred to as revitalization. ( Marine Mitchell, 2009). As the transmigrate potential comes back down towards its resting potential level and the potassium channels begins to close, the transmittance potential level goes just below -map, causing a brief period of hyperventilation (Martini, Nathan Bartholomew, 2012). Finally, as the potassium channels close, the membrane turns back to its resting potential until it is excited or inhibited again. In this experiment we will be dealing with two chemicals that intend to inhibit a nerve impulse. Curare is a toxic substance that interferes with the neural remission between motor neurons and skeletal muscles. Curare competes with acetylenes -or Ach- for receptors on muscle cells. Acetylenes is a chemical messenger that normally transmits nerve impulses and activates muscles receptors. Schaeffer, 2010). Loading is a chemical substance that inhibits the transmission of nerve impulses by blocking An ion flux across nerve membranes. In other words Loading is a local anesthetic that blocks voltage- gated An channels at low concentrations, it would make it harder to reach the threshold for firing action potential at high concentrations, and it would stop the action potential entirely. Materials/ Methods This experiment was conducted using the lab manual Human Anatomy Physiology by Marine Mitchell, 2009. Exercisers neurophysiology of Nerve Impulses on Physiology 8. 0 page 131 The activities that were used in this exercise were o Activity 6- testing the Effects of curare page 131 o Activity 7- Testing the Effects of Loading page 131 Results Effects of Curare versus Loading on a Nerve Voltage (NV)Action Potential Notes Curare 2. 0 NV Inaction potential begins at 3. NV Amplitude increases by very little and remains constant soon after. 3. 0 NV Yes 4. NV yes Loading 2. 0 NV No No action potential is recognized 3. NV No 4. NV No Using a frog nerve, two inhibitory chemicals were place onto the nerve to determine what inhibitory properties were seen after stimulating at the threshold voltage for this nerve. Discussion To have a better understanding of the respond to a stimulus and action potential of a nerve (In this case a frog sciatic nerve) we executed this experiment, and realized that numerous physical and chemical factors can impair the ability of a nerve to function. On the first exp eriment we used Curare that at 3. NV created an action attention on the nerve. At the neuromuscular junction, the action potential occurs in the presentation motor neuron, which releases acetylenes during an action potential. Synapses is a junction between two neurons. The presentation neuron terminal is the one that releases a neurotransmitter in response to an action potential. The posthypnotic neuron is the one that receives the neurotransmitter and may undergo an action potential (and become a presentation to the next nerve cell) if the neurotransmitters stimulate the cell enough. When curare is present, it will block acetylenes from binding to its acceptors on the muscle fiber, in turn stopping the muscle from contracting. They key point is that this effect is exclusively post synaptic. The presentation neuron still fires the identical action potential with or without the drug, it still release neurotransmitter. When curare is present, only the downstream effect is blocked. Loading showed success by having an inhibitory effect on a nerve impulse. With a range of electrical voltages from 2. NV to 4. 0 NV, no action potential was shown. This is what an inhibitory chemical intends to do inhibit any response by binding to the axon terminals of the presentation neuron. Specifically, it blocks the voltage-gated sodium channels that allow the influx of sodium when the nerve reaches the threshold voltage thus preventing an action potential. No action potential means no nerve impulse. A nerve must be stimulated and that stimulation must meet or exceed the threshold le vel required for activity to follow. Then as an impulse occurs, such as the nerve with loading being stimulated there must be either a period of inhibition or excitement that causes the membranes permeability to change. If a stimulation was intended to be excitatory the process of generating an action potential would occur, followed by revitalization and hyperventilation. However, in inhibitory responses, the goal is to see no action potential. If the intention is to prevent a stimulus from occurring, creating an action potential is not desired. It is important to understand the properties of substances such as these to better understand their intended effect. In order for them to be used properly one must know what intention of these substances to then provide a proper use for them. For example, one WOUld not propose to administer loading to someone who has regular heart function, because that would suppress their art levels below the threshold level. In conclusion nerve impulses all begin with a stimulus that either causes excitement or inhibition from a certain stimulus (Marine MitcheIl, 2009). If a nerve is excited the process of creating an action potential follows in order to achieve a chemical synapse. In other words, when a nerve is stimulated certain messages able to be transported in and out of the cell. However, in an inhibitory response such as the one witnessed with loading. This experiment determined the difference in excitatory versus inhibitory stimuli in a nerve. It allowed us to visualize the synaptic activity occurring based on a certain chemical which allows us to better understand the effects certain substances have on nerves.

Mideast Conflict essays

Mideast Conflict essays As America faces another showdown against Iraq, the Mideast conflict is possibly the single most important factor for our countrys war against terrorism. To fully understand the Israeli-Palestinian conflict, one must know the history of the region. This paper will attempt to provide an objective view on the situation and offer a plan for lasting peace in the region. An individual might begin this discussion in early times (3000 B.C.). However finding solid, factual data from this period is challenging, and often the facts vary depending on from which perspective the data is written. Obviously, this land has been contested since the beginning of time. Following is a rough timeline of events that shaped the current Middle East situation. Statements in a standard font are generally facts, which both sides agree upon. Statements in bold type are comments that are generally neutral. Statements in red type are the Palestinian, Arab viewpoints. Statements in blue type are the Jewish, Israeli viewpoints. 1. Jews and Arabs pray to a different God. Both sides claim that the West Bank is the center of their homeland. 2. In World War I, Britain gained control of the land of Palestine with Arab aid. After Britain gained control of the region, they promised Jewish leaders a national home in the land of Palestine. Britain also promised the creation of an independent Arab state. Both sides generally agree to this statement. 3. The British mandate officially began in 1922, which was approved by the League of Nations. The White Paper (1922) stated Britains policy of aiding Jews return to their homeland. Additionally, there were limits placed on the number of Jewish immigrants that should be admitted into the region. This statement is also generally agreed upon. But, the number of Jewish immigrants was supposed to be limited to 25,000, but the actual number of immigrants was closer to 50,000. This ...

Team Project Evaluation Paper - Essay Example The group would thereafter indicate how these attributes compare to those of a larger group. In this regard, the group work will show how the larger group’s development is more complex, how they have less freedom to operate, how they use complex communication, how they receive lower satisfaction, how they make slower decisions, how they develop sub-teams, how they have a higher turnover, how they have higher absenteeism, and how they expand the group knowledge. The case scenario that will be used to achieve the above-mentioned objectives is about aliens landing on the planet Earth, first in a small group and then in large group. The study will explore how these different groups act differently and the differences in their behavior based solely on the number of members in each group. In the representation of aliens, the study will use action figures, dolls, and stuffed animals, among others. By doing this we can alter the numbers much easier than if we used real people. Also I believe these â€Å"actors† will be able to have a stronger personality and be able to switch more easily between a small group and a large group since it is only their voices, which will be used, and hence I feel everyone will not be holding back with shyness as much. The genre of the video will be strictly comedy. Therefore, the objective of the video is to make people laugh since we do not want our audience falling asleep and this is another reason why we used things like toys to represent human beings. We are going for a PG 13 to R rated Toy Story vibe based on how intense we can get. There will be a lot physical and verbal comedy based on random actions. For example, in the small group the aliens might be smoking marijuana because they have more freedom to operate, but in a large group you will see that there is less freedom to operate so if an alien starts smoking they will probably be fired. Performance Norms Effort In normal sense it is required that every group membe r should put in a 100 % effort, but as we know this is usually not the case in most group projects. However, the group leader is guaranteeing to put too much effort, to an extent that it will not matter if a few members of the group start to slack. The ideal situation is to have constant communication since this is the most important thing in a successful working relationship. We expect for everyone to text each other back as soon as possible after they receive a text from any group member and if any group member takes longer than a twelve-hour period or the member does not text back at all, he or she will be called upon to explain the lack of communication. We will ensure we stay on the set time schedule by working on a one single concept and this would eliminate the need to reshoot the scenes a bunch of times. We will get the filming portion done all in one day so there will be no chopping of certain scenes during the editing process and the plot of the comedy will remain consiste nt. It is expected that everybody will put their best effort in on that day and no one will be absent during this crucial day. We will not accept any excuses from our members for poor attendance. In addition, enthusiasm and initiative will be expected during the filming stage since failure will not be an option but nevertheless overall A effort is expected from everyone and anything less is frowned upon. Output It is expected th

Ethics paper Case Study Example | Topics and Well Written Essays - 1000 words

Ethics paper - Case Study Example I would like to provide the reasoning for that decision and would also like to point out the ethical issues that have risen for the company. The company being one of the large automobile manufacturers of the world produces two different types of vehicles, one being the SUV’s and the other being the light trucks. Of late, the company has faced issues remaining profitable for its shareholders. There are about 1,000,000 of these types of vehicles on the road and all of them having a good reputation amongst its customers. The engineers in the company have found some balancing issue in the vehicles and due to that the company had to face five law suits lately. All those law suits had to be settled amounting to $500,000 in total. To fix the balancing issue in the vehicle, it would cost $180 per vehicle after all the vehicles would be recalled. The main ethical issue that is to be considered is the knowledge of the defect in the vehicles not been conveyed to the customers. Although the company has faced five different legal proceedings, it has dealt with them with any disclosure made to the public at large. This issue of not disclosing the information to the public may cause severe damages as all the customers using the vehicles face the risk of death in an accident. This may cause the drivers of the vehicles to face severe accident which may life threatening or may cause any other disability to the drivers of the vehicles. Recall the vehicles; this would cost the company around $18,000,000 but in such a drastic period where profits have been deteriorating, the shareholders would not agree to this. This $18,000,000 would be a major cost that the company would have to bear and because of this cost the other stakeholders that might get affected are the employees. The employees would have to be paid extra for the additional work to be done, this would further upset the shareholders as the profits would further diminish and have a negative
