Law - Essay Example Issues Relevant to The Contract for the Sale of the Van Misrepresentation In negotiating for the purchase of a van from Daly, Winston explained that the putative van must have a storage capability of 200 feet and must be capable of regularly transporting antique furniture up to 1 ton. Based on these requirements, Daly told Winston that he had a van the fit Winston’s requirements and a van was offered for sale and accepted based on Daly’s representations. In fact, Daly also noted that the van in question had hardly been broken in. It is a fundamental rule of contract law that the parties to a contract enter into a contract on the basis of an understanding that they will receive the benefit bargained for and forming the inducement to enter into the contract.1 In addition, should one of the contracting parties fail to perform as mandated pursuant to the contract, the party losing the benefit bargained for and reflected in the contract for sale, is entitled to compensation for that loss.2 When the party loses the entire benefit of his or her bargain, he is entitled to treat the contract as terminated.3 Under the contract for the sale of the van, Winston was promised and expected to receive a van capable of replacing the van lost in the conduct of the antique shop’s business. The truck however, turned out to be inadequate as a replacement vehicle. The question is therefore whether or not the van’s failure to live up to expectations amounts to a breach of the contract on Daly’s part. Daly did make certain representations or as it turned out, misrepresentations that the van in question was fit for purpose. Misrepresentation occurs when false information is communicated and that false information induces the other party to enter a contract to which the false information applies.4 Misrepresentation can be made fraudulently or negligently or innocently.5 It is difficult to discern from the facts of the case for discussion whether or not the false information provided by Daly that the van was fit for its intended purpose was negligent, innocent or fraudulent. However, as a skilled or experienced salesman, it can be assumed that at the very least, Daly ought to have known whether or not the van was fit for purpose. It is therefore reasonable to assume that Daly’s misrepresentation was negligent at the very least. Regardless, it will be for Winston to prove that he relied on the information communicated to him or was induced by that information to enter into the contract.6 It can be assumed from the facts that Winston did in fact rely on Daly’s communication of facts since he was looking for a specific van with specific requirements and communicated those facts to Daly. Fit for Purpose Quite apart from misrepresentation, Winston can consider taking action against Daly under statute. By statutory law, it is an implied term of contracts for the sale of goods that goods purchased for a specific purpose are fit for purpose. By virtue of Section 14 (3) of the Sale of Goods Act 1979, where a purchaser either â€Å"expressly or by implication makes known to the seller† it is implied that the â€Å"goods supplied under the contract are reasonably fit for that purpose† unless the purchaser â€Å"does not rely,† on the â€Å"skill or judgment of the seller†.7 Winston can prove that he rel

Animals In Captivity Essay In 2008 at the Singapore Zoo, three white Bengal tigers attacked and mauled a zoo cleaner, Nordin bin Mondongto, to death after the man walked through a moat surrounding their enclosure. Researchers asked themselves what would be the cause of these vicious behaviors being reported from many zoos across the globe, the answer being the harsh environment zoo animals are surrounded by. Many people are not aware of the harsh treatment the animals endure. Zoos, circuses, and famous attractions like SeaWorld do not offer the best of circumstances for their animals. These uncomfortable conditions may be the cause of the hundreds of violent behaviors being reported by zoos around the world. Of course, most families enjoy taking a trip to the zoo because they offer a unique experience of encountering exotic animals. However, people need to realize that animals are living creatures that should not be forced into show, or held behind glass walls to be gawked at. The first point that this essay will address is the simple fact that zoo owners have propaganda in mind, and not preservation. â€Å"Zoos help save endangered species, by saving hurt animals and rehabilitating them,† is an excuse many zoo officials use. Zoos claim to want to protect species from extinction, which sounds like a noble goal, but zoo officials usually favor exotic or popular animals, rather than threatened or endangered local wildlife. The Chinese government, for example, â€Å"rents† pandas to zoos worldwide for fees of more than $1 million per year. It is questi onable whether the profits are being directed toward panda-conservation efforts at all. Also, because tigers are the most favorable â€Å"crowd pleasers,† recent studies prove that there are more tigers in captivity than those that exist in the wild. There are thought to be between 5,000 and 10,000 tigers in U.S. cages and 90% of them are in miserable roadside zoos, backyard breeder facilities, circus wagons and pet homes. Before long, the few tigers left in the wild will wither off, and the animals in captivity will not be able to be relocated and thrive in their what-once-was natural environment. Next, the reader should know that the animals that are said to be â€Å"in their natural habitat,† are in confined areas that are less than a tenth of the area they would naturally be in, and are restricted by many factors. Birds’ wings may be clipped so that they cannot fly, aquatic animals often go without adequate water, and many animals who naturally live in large herds or family groups are kept isolated. Animals are closely confined, lack privacy, an d have  little opportunity for mental stimulation or physical exercise. These abnormal conditions often result in abnormal and self-destructive behavior, known as â€Å"zoochosis.† An Oxford University study based on decades of observing animals in captivity and in the wild found that animals such as polar bears, lions, tigers, and cheetahs â€Å"show the most evidence of stress and/or psychological dysfunction in captivity† and concluded that â€Å"the keeping of naturally wide-ranging carnivores should be either fundamentally improved or phased out.† Last but not least, the reader should know that keeping animals in captivity is not the only danger posed at the zoo. Even when the animals are bred in captivity, generations later, exotic animals will retain all of their natural instincts. They cannot be considered â€Å"domesticated† or â€Å"tamed.† Every year, captive, exotic animals are involved in incidents in which humans are injured or even killed. In 2007, Tatiana, a Siberian tiger, escaped her substandard enclosure at the San Francisco Zoo and was shot to death after she killed one person and injured two others. This was not the only fatal incident occurring because of the animals being held in captivity. On February 26, 2010, a 12,000 lb. Orca whale called Tilikum mauled and killed his trainer Dawn Brancheau at SeaWorld during a performance. Also, in Colorado, on April 24, 2009, a volunteer was vigorously mauled by a tiger at â€Å"Big Cats of Serenity Springs.† The list of these aggressive outbreaks goes on and on. Researchers say that the awful conditions animals are unnatural and are the cause of animals expressing abnormal behaviors. Zoos may be fun for the family, but are definitely not fun for the animals. Taking animals out of their natural habitat, forcing them to live miserable lifestyles, and putting humans at risk is not worth a fun family trip to the zoo. Treating living creatures like they have no feelings is never okay and should be considered inhumane. Zoos need to be exposed as the pitiful prisons they are, and actions should be imposed to stop the animal abuse.

Nanotechnology In Architecture

Nanotechnology In Architecture Historically and geographically human have lived in extremely varied technology or environment and have had to adapt to comfort habitats and thus the architects have had to manage the ideal of design as well as incorporate the evolutionary technology. A technology has evolved to a level where it is just too complex. Sometimes satisfying the need of the user and sometimes becoming too dangerous when the negative consequences are not taken care of. For example, the issues of the Large scales in architecture is one such matter which has been partially solved with the help of low cost materials, energy savingà ¢Ã¢â€š ¬Ã‚ ¦etc. The scientists have developed and are continuing to develop nanotechnology to help architects incorporate more artificial intelligence in construction. Nanotechnology is a combination of various fields of science like, Bio- technology, Chemistry, Physics, Bio-informatics, etc. There are three chief divisions in Nanotech: Nanoelectronics, Nanomaterials, and Nano-Biotechnology. Worldwide, there is much enthusiasm about nanotechnology as it has application in medicine, electronics, biomaterials, energy etc. It is observed that US, Japan, and Germany dominate the current RD effort in nanotechnology with a focus on they own expertise and needs (Hyd and spook, 2012). The use and control of the technology at an atomic or particle scale known as nanotechnology has started to have its impact like never before in materials of constructions and has immense futurist impact in architecture, this application of the nanotechnology and nanomaterials in architecture is NanoArchitecture. The nano world in technology is a real challenge for todays designers, it started with an understanding and control of the technology and materials on one billionth (10-9) scale. The understanding of these materials, its use in architecture to be profitable for users and its implication on the building (Construction) are some of the key aspect for inquiry in this dissertation. With the perfect solution of this dilemma, the Architects would not only know how big their task is but how it might lead to new ways of thinking architecture. After understanding the meaning and origin of this technology, we will study certain aspects that is a must in todays constructions and then we see the direction where this science is going, we will also look at the ways to incorporate these technologies in our architecture, therefore the question that will guide our research is how does nano (technology, materials, science, concept, form and function) become important to the level of influencing architects (designers). Nanotechnology is developed in the manner that it is active or passive, this repartition will lead us to a large study but our focus will rely on the relation passive active nanostructure and application of nanotechnology in a building design and construction. Passive nanotechnologies, such as nanocoatings, nanoparticles, and nanostructured materials, are already available. Second generation active nanostructures, for example, nanoelectro-mechanical systems, nanomachines, self-healing materials, and targeted chemicals, can evolve their properties, structure and/or state during their operation. This could increase nanotechnologys impacts and require new approaches for risk assessment. Active nanostructures are likely to have a different and increased profile of impacts (including benefits as well as potential risks) compared with passive nanotechnologies. RESEARCH QUESTION: How does nano (technology, materials, science, concept, form and function) becomes important to the level of influencing architects (designers). NEED IDENTIFICATION: Over the years the materials used in buildings (during construction, inside or outside finishes) has been of a large scale, the evolution today have brought into existence the materials on a microscopic scale with even more value to life and building. They can be metals, ceramics, polymers or composites. Known as nanomaterials, nanocomposites, and manufactured nanomaterials (MNMs), the method of making these materials begins at the molecular or atomic level, sometimes creating new products with extraordinary physical and chemical properties. For example, a carbon nanotube has strength of 150 times that of steel but is approximately six times lighter. Besides strength enhancement, properties can include self-cleaning, super hardness, electrical conductivity, antimicrobial superior thermal resistance and stability, non-flammability, lightweight, anti-corrosion, superior barrier, light emitting and low permeability, among others. Applications in the building industry include use as fire retardants, high performance insulation, protective coatings, equipment lubricants, structural integrity enhancement and monitoring, photovoltaic, stronger tensile cables, and self-cleaning or heat absorbing windows ( CFN, 2011 )à ¢Ã¢â€š ¬Ã‚ ¦ Using these materials which contain extraordinary application in the building can also bring amazing influences to the architect, designer or the design. Therefore apart from attempting to understand the transformation that the nanotechnology brings to our building there is a need to understand by students the uses of nanotechnology for creating better design. SCOPE: à ¢Ã¢â€š ¬Ã‚ ¢ A general understanding of nano especially toward architecture à ¢Ã¢â€š ¬Ã‚ ¢ Nanotechnology (materials) applications in buildings à ¢Ã¢â€š ¬Ã‚ ¢ Concept; form and function derived from nano LIMITATION: à ¢Ã¢â€š ¬Ã‚ ¢ The laboratories details of certain materials and nano applications in medical branches will not be part of our research. à ¢Ã¢â€š ¬Ã‚ ¢ This research dissertation will have some limitation in details like calculations, manufactures process, chemical components. à ¢Ã¢â€š ¬Ã‚ ¢ Thinking in more detail about how to use nanomaterials in a design context, a first consideration is simply to define what is being design?. But there is a lack of built case studies, so we will rely on existing, futurist, basic concept and reading materials. à ¢Ã¢â€š ¬Ã‚ ¢ Regarding the size of this matter nanotechnology, we will limit at the level where nanotech is active and very briefly talk about the passive Nanotechnology RESEARCH METHODOLOGY: N A N O A R C H I T E C T U R E PART O.

The reading of the applications in nanotechnology in todays constructions is more related to Green designers, this part of the design has an impact in the ecology and climate control therefore the green rated buildings has in fact a considerable amount of nanotechnology use in it. This leads us to refer to architects involved in green concepts or sustainability from LEED etc ( Ar Alex Nyembo Kalenga) and also we could make a visit studies on the actual certified Green building Rajiv Gandhi urja Bhavan at Vasan Kunj New Delhi Still in Construction.

Fundamental Knowledge II.1.1. WHAT IS NANOTECHNOLOGY? A brick is the smallest building block in construction. Whatever you do, the strength of the building is limited to the strength of the brick. The brick itself is made of minute particles of clay bonded together. One has limited control over how the particle of clay forms. Each particle of clay in turn is formed from molecules joined together in a particular pattern dictated by the forces of nature. What happens if it is possible to arrange these molecules in a pattern that provides greater strength? You get stronger clay and a stronger brick. This results in a much thinner, but stronger wall. This technology of arranging molecules the way we want is a basis of nanotechnology. (Johnzactruba, 2011) A strict definition of nanotechnology characterizes it as the manipulation of a matter at the scale of one-billionth of a meter or smaller. The measurement of one-billionth of a meter is identified as one nanometer (nm) (Jeffrey H. Matsuura,1957). Nano, is a word which does not only mean billionth less but also leaves a billionth of question in mind, because of the complexity to understand its simplicity. It is a world hold by the scientist, chemist and physicians. Yes nanotechnology is a relatively recent development in scientific research but not new. The level of its study and diversity has involved touching now many sector of life and becoming more and more known by the public. The concept first was introduced by American physicist Richard P. Feynman (1918-1988). But it is noted that in the 10th centuries the 16th centuries the ruby-red color of many stained-glass windows from the medieval era was a consequence of embedded nanoscale metallic particles within the glass. There were no scientific understanding of these phenomena at the time, nor were there deliberate attempts to produce what we now know as nanomaterials. Early knowledge relied on craft-based trial and error to achieve effects we must keep in mind, however, that not all interesting color phenomena are a result of embedded nanomaterials ( Michael F. Ashby, 2009). The evolution of nanotechnology has been more or less in the domain of chemical, medicine and physics (technique) then it involved to the environment, energy, agriculture, communication and information because of some of its advantage and disadvantage in the society. The main tools used in nanotechnology are three main microscopes: Transmission Electron Microscope (TEM), Atomic Force Microscope (AFM), and Scanning Tunneling Microscope (STM). (Jamie Jackson, CIS 121) II.1.2. NANO PRODUCTS Use as gateways to build other nano products, Nanosensors can be chemical sensors or mechanical sensors. Amongst other applications they can be used: à ¢Ã¢â€š ¬Ã‚ ¢ To monitor physical parameters such as temperature, displacement and flow à ¢Ã¢â€š ¬Ã‚ ¢ As accelerometers in Microelectromechanical systems (MEMS) devices that can rapidly and remotely detect change in their surroundings like airbag sensors à ¢Ã¢â€š ¬Ã‚ ¢ For medical diagnostic purposes either as blood borne sensors or in lab-on-a-chip type devices à ¢Ã¢â€š ¬Ã‚ ¢ To detect various chemicals in gases for pollution monitoring à ¢Ã¢â€š ¬Ã‚ ¢ Sensors using carbon nanotube detection elements are capable of detecting a range of chemical vapors. These sensors work by reacting to the changes in the resistance of a carbon nanotube in the presence of a chemical vapor ( Hawks Perch Technical Writing, 2007). II.1.2.1. Nanotube Known as well as Carbon Nanotube (CNTs), it is a tube-shaped material or cylindrical nanostructure made of carbon, having a diameter of nanometer scale. Nanotubes form a tiny portion of the material(s) in some baseball bats, golf clubs, or car parts. Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (GPa). Since carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm3, its specific strength of up to 48,000 kNà ¢Ã¢â€š ¬Ã‚ ¢mà ¢Ã¢â€š ¬Ã‚ ¢kgà ¢Ã‹â€ Ã¢â‚¬â„¢1 is the best of known materials, compared to high-carbon steels 154 kNà ¢Ã¢â€š ¬Ã‚ ¢mà ¢Ã¢â€š ¬Ã‚ ¢kgà ¢Ã‹â€ Ã¢â‚¬â„¢1. Standard single-walled carbon nanotubes can withstand a pressure up to 24GPa without deformation. The bulk modulus of super hard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal) and can produce materials with toughness unmatched in the man-made and natural worlds. Because of the carbon nanotubes superior mechanical properties, many structures have been proposed ranging from everyday items like clothes and sports gear to combat jackets and space elevators. However, the space elevator will require further efforts in refining carbon nanotube technology, as the practical tensile strength of carbon nanotubes can still be greatly improved (Wikipedia, 2012). II.1.2.2. Nanocomposites The definition of nano-composite material has broadened significantly to encompass a large variety of systems such as one-dimensional, two-dimensional, three-dimensional and amorphous materials, made of distinctly dissimilar components and mixed at the nanometer scale (Kanatzidis, 2006). New materials with novel proprieties are generate rapidly through this field. The properties of nano-composite materials depend not only on the properties of their individual parents but also on their morphology and interfacial characteristics. Although nanoscale reinforcements (or nanofillers) of nanocomposites have different kinds of fillers such as nanofibers, nanowires, nanotubes and nanoparticles etc, their mechanical behaviors have some common features. As the figure shows a potential use of nanocomposites as multifunctional materials (Journal Club, 2008). AREA OF APPLICATION Such mechanical property improvements have resulted in major interest in nanocomposite materials in numerous automotive and general/industrial applications. These include potential for utilisation as mirror housings on various vehicle types, door handles, engine covers and intake manifolds and timing belt covers. More general applications currently being considered include usage as impellers and blades for vacuum cleaners, power tool housings, mower hoods and covers for portable electronic equipment such as mobile phones, pagers etc (Professor J.N. Hay, 2001). The inorganic components can be three-dimensional framework systems such as zeolites, two-dimensional layered materials such as clays, metal oxides, metal phosphates, chalcogenides, and even one-dimensional and zero-dimensional materials such as (Mo3Se3-)n chains and clusters. Experimental work has generally shown that virtually all types and classes of nanocomposite materials lead to new and improved properties when compared to their macrocomposite counterparts. Therefore, nanocomposites which combine new nanomaterials with more traditional ones such as steel, concrete, glass, and plastics, can be many times stronger than standard materials and promise new applications in many fields such as mechanically reinforced lightweight components, non-linear optics, battery cathodes and ionics, nano-wires, sensors and other systems. On the market there already a nanocomposite steel that is three times stronger than conventional steel. Before long, nano-reinforced glass might be used for both structure and enclosure. In the some student projects in the nanoSTUDIO at Ball State University, nanotube structural panels create transparent load-bearing curtain walls free of columns and beams, quantum dots make walls and ceilings light up or change color with the flip of a switch, and nanosensors in building components create smart environments that constantly adapt to their environment and users. II.1.3. TYPOLOGY M. C. Roco, one of the driving forces behind the NNI, has developed a more detailed typology of nanotechnologies. He identifies four generations of nanotechnologies: passive nanostructures, active nanostructures, systems of nanosystems and molecular nanosystems (J. Clarence, 2009) ( Fig04: For generation of nanotechnology development, Center for Responsible Nanotechnology ) Each generation of products is marked by the creation of commercial prototypes using systematic control of the respective phenomena and manufacturing processes. Products may also include components which correspond to different generations. Todays rudimentary capabilities of nanotechnology for systematic control and manufacture at the nanoscale are expected to evolve significantly in both complexity and the degree of integration by 2020. II.1.3.1 Passive to Active nanotechnology It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment. An active nanostructure changes or evolves its state during its operation, according to the National Science Foundations (2006) Active Nanostructures and Nanosystems grant solicitation. Passive: (steady function) nanostructures Behaviour: inert or reactive nanostructures which have stable behaviour and quasi -constant properties during their use. Potential risk: e.g. nanoparticles in cosmetics or food with large scale production and high exposure rates. Active: (evolving function nanostructures) Behaviour: the nanostructures properties are designed to change during operation so behaviour is variable and potentially unstable. Successive changes in state may occur (either intended or as an unforeseen reaction to the external environment). Potential risk: e.g. nanobiodevices in the human body; pesticides engineered to react to different conditions. Categories of active nanostructures are: à ¢Ã¢â€š ¬Ã‚ ¢ Remote actuated active nanostructures, such as light-actuated embedded sensors; à ¢Ã¢â€š ¬Ã‚ ¢ Environmentally responsive active nanostructures, such as responsive drug delivery; à ¢Ã¢â€š ¬Ã‚ ¢ Miniaturized active nanostructures, such as synthetic molecular motors and molecular machines; à ¢Ã¢â€š ¬Ã‚ ¢ Hybrid active nanostructures, or uncommon combinations of materials, such as silicon-organic ; à ¢Ã¢â€š ¬Ã‚ ¢ Transforming active nanostructures, such as self-healing materials. (M.C. Roco, 2004, 2007) Tour estimates the time it will take to commercialize each of these types as 0-5 years for passive nanotechnologies, 15-50 years or more for active nanotechnologies and 7-12 years for hybrids (J. Clarence, 2009) II.1.4. WHY ALL THE FUSS ABOUT NANOTECHNOLOGY? NANOTECHNOLOGY: THE SCIENCE CHANGING YOUR LIFE Penny Sarchet The advantages of using nanomaterials in construction are enormous. When you consider that 41 percent of all energy use in the United States is consumed by commercial and residential buildings, the potential benefits of energy-saving materials alone are vast (Dr. Pedro Alvarez of Rice University, 2010) and when we have to evaluate the energy used by buildings in the rest of the world the result will surly show that the use of the nanomaterials in buildings will be of an anxiety necessity. Nanotechnology thus has profound potential because it can free us from some traditional limits and offer us useful new capabilities. Nanotechnology can change some of the physical rules that have traditionally confined us. It can also free us from some of the limitations that have long been placed upon us by size ( Jeffrey H, 1957). The key is to understand the specific risks and implications of the product before it is widely used. This way we can ensure that nanotechnology evolves as a tool for sustainability rather than as an environmental liability (Dr. Pedro Alvarez of Rice University, 2010). Benefices and profit with the nanotechnology is now in the hand of everyone and architects are with no doubt going to shape this realm to another level. e.g.: Solera enables seamless integration of natural daylight into the design and function of buildings. Well daylighted spaces deliver substantial and measurable benefits to sustainability, energy efficiency and human performance. This series of products provide architects with solutions to solve the challenges traditionally associated with daylighting techniques including solar heat gain, cost, complexity and glare. Other materials such as brickà ¢Ã¢â€š ¬Ã‚ ¦ have already showed us the changes that it has done to the industries, life, designers, buildersà ¢Ã¢â€š ¬Ã‚ ¦ In the early days, paint was available in a limited variety of colors for you to choose. Now most of the paint shops have mixers that allow the users to choose the color they require. The manufacturers have to produce and stock only a few basic colors, reducing production and inventory costs at much greater satisfaction to the consumer. The future of nanotechnology will be the personal nano-factories, like the paint mixers, that allow you to produce any material that you require. The shops have to carry only stock in molecular form. Advances in nanotechnology are moving at an exponential rate. It will eventually encompass every field of human activity including energy. (Johnzactruba, 2011) Disadvantages of Nanotechnology: Safety hazards with nanomaterials, Some studies detected possible cancer-causing properties of carbon nanotubes, Some nanomaterials bounded with other materials or components (Jamie Jackson, CIS 121) II.1.5. RISK OF NANOTECHNOLOGY It is obvious to find out that except from the greatness and impressive opportunities that nanotechnology offers, the risks are associated with it as well. And these risk touch-up on Health, environment, Industryà ¢Ã¢â€š ¬Ã‚ ¦ Because of the size of the particles, nanomaterials may enter human and other living bodies and disrupt body-functions. Some nanoparticles may also be non-biodegradable thereby posing a new threat to the environment. Therefore it is crucial to examine and estimate the risk for regulating the production, use, consumption and disposal of these materials. (Hyd and spook, 2012). For example, Health effects of several insulating materials are a concern; 1. The fibers released from fiberglass insulation may be carcinogenic, and fiberglass insulation now requires cancer warning labels. 2. There are also claims that the fire retardant chemicals or respirable particles in cellulose insulation may be hazardous (Dr. George, 2007). The risk most talked about is the ability of nanotech carbon tubes to potentially cause asbestosis-type illnesses, (Mike Childs, 2012) Manufactured nanomaterials (MNMs); and nanocomposites are being considered for various uses in the construction and related infrastructure industries. To achieve environmentally responsible nanotechnology in construction, it is important to consider the lifecycle impacts of MNMs on the health of construction workers and dwellers, as well as unintended environmental effects at all stages of manufacturing, construction, use, demolition, and disposal. Emphasis in industries; In India, late industry participation has also begun in this area, and there is an emphasis on fostering public-private partnerships (PPP). Nonetheless government support to this sector remains crucial for three reasons: 1. Nanotechnology is a capital-intensive technology and is in an embryonic phase, thus industry would not be able to sustain the research effort needed for the establishment of scientific and technological infrastructure. 2. The state is required to define the regulatory framework. In 2010-11 this process was initiated. 3. The state ,particularly in the developing country context, can set the agenda and resist the tendency to uncritically follow international trends in research that do not address their developmental needs.

III.1. Environmental application Environmentally, Nanotechnology also has the potential to help our environment. Example: It controls pollution through source reduction. This is a method of eliminating toxic waste at its source, with the understanding that releasing the waste into the environment is the last resort. Source reduction can be achieved by cleaning up existing processes or by reducing consumption of resources where such consumption creates pollution. III.1.1. Insulation The impact of the improvement of insulation reductions is counted by billions of pounds annually. Ref table (Fig06: Potential sources of EU CO2 emission reductions ) Nanoscale materials hold great promise as insulators because of their extremely high surface-to-volume ratio. This gives them the ability to trap still air within a material layer of minimal thickness (conventional insulating materials like fibreglass and polystyrene get their high insulating value less from the conductive properties of the materials themselves than from their ability to trap still air.) Insulating a nonmaterial may be sandwiched between rigid panels, applied as thin films, or painted on as coatings (Dr. George, 2007) Nanogel panels; Aerogel This material as an incredible ability and capacity such as strength, it can take its own load 2000 times reminding that it has only 5 percent solid and the rest is filled with air only an are also applicable on fabric architecture or structures. Because nanoporous aerogels can be sensitive to moisture, they are often marketed sandwiched between wall panels that repel moisture. Aerogel panels are available with up to 75 percent translucency, and their high air content means that a 9cm (3.5) thick aerogel panel can offer an R-value of R-28, a valu

Graduation Speech -- Graduation Speech, Commencement Address

Henry Adams once wrote "A teacher affects eternity; he can never tell where his influence stops." This is so true, every teacher here has taught us much more than the textbook curriculum. Every teacher here tonight has given us students something we will use or remember for the rest of our lives. I really don't think people understand or appreciate the time and effort our teachers have put into us. So tonight I'm not going to give everyone advice on the future, I'm not going to tell you how life is a journey we've just begun, and I'm not going to brag about how great the class of 2006 is. Since we have eight outstanding Valedictorians this year, I'm sure all of those bases are already covered. So instead, I'm going to take a few minutes here to thank some of the teachers and staff that have made a difference in my own life, and by doing so I hope that everybody present tonight will see how important each and every teacher and staff member is at Amos High School. I'd like to start out by thanking Mr. Addington. Not only is he the Clay and Ceramics teacher at AHS, he is the wisest man I know. I have asked him so many questions this year, and he has always helped me figure things out, but instead of letting me be lazy and simply telling me his answers, he asks me the questions and makes me think it out. Mr. Bassett is the smartest man I know. He keeps the entire school district's computer network up and running, he created a computer program that lets kids and parents check their grades from their home computers, as well as another program that he sold to the government. While doing all this, he still made extra time to help me survive his Windows 2000 class since I hadn't taken the required prerequisites and was pretty lost. Mr.... ...already talked about, and the ones that I did not get a change to mention, but I don't have time. Parents and people of the community, please see what great people these teachers are, and remember how much of their lives they give freely to their students. Teachers, whether you know it or not, you have affected each of us so much. The people that I have talked about are only teachers on my own list of important people at Amos High School. Every single student in a cap and gown right now has their own list, every one of you has impacted someone's life, and we will never forget you. Without your time and effort, none of us would be where we are today, and none of us would have been the leaders that we will turn out to be. You have made our experience at Amos High School truly great, and it will be hard to say goodbye, but from the graduating class of 2006, thank you.

Shallow Foundation

Shallow foundations Shallow foundations are those founded near to the finished ground surface; generally where the founding depth (Df) is less than the width of the footing and less than 3m. These are not strict rules, but merely guidelines: basically, if surface loading or other surface conditions will affect the bearing capacity of a foundation it is ‘shallow'. Shallow foundations (sometimes called ‘spread footings') include pads (‘isolated footings'), strip footings and rafts.Shallows foundations are used when surface soils are sufficiently strong and stiff to support the imposed loads; they are generally unsuitable in weak or highly compressible soils, such as poorly-compacted fill, peat, recent lacustrine and alluvial deposits, etc. Pad foundations Pad foundations are used to support an individual point load such as that due to a structural column. They may be circular, square or reactangular. They usually consist of a block or slab of uniform thickness, but th ey may be stepped or haunched if they are required to spread the load from a heavy column.Pad foundations are usually shallow, but deep pad foundations can also be used. Strip foundations Strip foundations are used to support a line of loads, either due to a load-bearing wall, or if a line of columns need supporting where column positions are so close that individual pad foundations would be inappropriate. The main area of strip foundation are buildings with heavy walls (brick, concrete, stone), and heavy floor slabs. Strip foundation is located on the perimeter exterior walls, and placed under the supporting inner walls of buildings or other areas with increased load.Also strip foundation is well-suited for homes, which is planned to create basement, garage or basement. Strip foundation is also suitable in the case of a possible slight deformation of the base. Typically, strip footing located below the level of soil freezing at 20 cm of sandy soil You can lay the strip foundation a nd higher levels of freezing, but not more than 60 cm from ground level. For deep-freezing and highly swelling soils usually strip foundation shall not apply. Process itself strip foundation construction is simple, on the other hand it requires a fairly high cost of materials and work on the construction of the foundation.There are criteria for the minimum thickness of the foundation, which can be used building a house. Thus, the minimum thickness of reinforced concrete strip foundation – 10 cm of concrete – 25 cm, rubble concrete foundation – 35 cm, well and laying of natural stone – 50 cm in the construction of strip foundation to be also take into account the permissible load on the soil under the foundation. For clay soils at a depth of 80 cm load should not exceed 2 kg/cm2. In addition to pouring the foundation concrete mixtures, often strip foundations erected using ready-made foundation blocks or bricks.This speeds up the process of building a foun dation. It should also be noted that during the construction of strip foundation is an opportunity to save money raising the foundation to the full depth only during the construction of heavy structures. There is still the most reliable option strip foundation remains solid foundation, more time-consuming and requires prior creating formwork and reinforcement training design to increase strength strip foundation. And in this case, the valves must be connected to each other by welding. Raft foundationsRaft foundations are used to spread the load from a structure over a large area, normally the entire area of the structure. They are used when column loads or other structural loads are close together and individual pad foundations would interact. A raft foundation normally consists of a concrete slab which extends over the entire loaded area. It may be stiffened by ribs or beams incorporated into the foundation. Raft foundations have the advantage of reducing differential settlements a s the concrete slab resists differential movements between loading positions.They are often needed on soft or loose soils with low bearing capacity as they can spread the loads over a larger area. Deep foundations * Piles Deep foundations are those founding too deeply below the finished ground surface for their base bearing capacity to be affected by surface conditions, this is usually at depths >3 m below finished ground level. They include piles, piers and caissons or compensated foundations using deep basements and also deep pad or strip foundations. Deep foundations can be used to transfer the loading to a deeper, more competent strata at depth if unsuitable soils are present near the surface.Piles are relatively long, slender members that transmit foundation loads through soil strata of low bearing capacity to deeper soil or rock strata having a high bearing capacity. They are used when for economic, constructional or soil condition considerations it is desirable to transmit lo ads to strata beyond the practical reach of shallow foundations. In addition to supporting structures, piles are also used to anchor structures against uplift forces and to assist structures in resisting lateral and overturning forces.Piers are foundations for carrying a heavy structural load which is constructed insitu in a deep excavation. Caissons are a form of deep foundation which are constructed above ground level, then sunk to the required level by excavating or dredging material from within the caisson. Compensated foundations are deep foundations in which the relief of stress due to excavation is approximately balanced by the applied stress due to the foundation. The net stress applied is therefore very small. A compensated foundation normally comprises a deep basement. Types of pilePiles are often used because adequate bearing capacity can not be found at shallow enough depths to support the structural loads. It is important to understand that piles get support from both e nd bearing and skin friction. The proportion of carrying capacity generated by either end bearing or skin friction depends on the soil conditions. Piles can be used to support various different types of structural loads. End bearing piles End bearing piles are those which terminate in hard, relatively impenetrable material such as rock or very dense sand and gravel.They derive most of their carrying capacity from the resistance of the stratum at the toe of the pile. Friction piles Friction piles obtain a greater part of their carrying capacity by skin friction or adhesion. This tends to occur when piles do not reach an impenetrable stratum but are driven for some distance into a penetrable soil. Their carrying capacity is derived partly from end bearing and partly from skin friction between the embedded surface of the soil and the surrounding soil.

Megan Renee Essays - Guiding Light, Free Essays, Term Papers Megan Renee Megan Renee Please, just let me hold her, she pleaded, just once? Im sorry, replied the plump nurse coldly, but I have my orders, and besides, it will only make things that much worse. To an outsider, it was a heart-wrenching scene. To the hospital, it was something that they dealt with on a daily basis. To her family, it was a mistake that never should have happened. To Sara, it was a day that changed her life forever. Katie, I cant look-tell me what it says, requested Sara Holten. Do you really want to know?asked her best friend Katie Landiman, comparing the results to the package instructions. I have to know, I dont have a choice here. Its positive Sara, youre pregnant, Katie said reaching out to comfort her friend with a hug, wishing she could help more. How could you do this to us? was the only thing Mr. and Mrs. Holten said when Sara told them. Her mother cried, and her father just turned away from her and didnt say anything. Her boyfriend Joel just reminded her that he had a football scholarship, and that he was in no position to take care of a child. He offered to pay for her to take care of it, and she left before he could say another word. Sara was only sixteen, but up until now, she was considered very mature and responsible for her age. She had a 3.7 grade point average in high school. She was going to graduate a year early, and had even begun to take classes at the local community college. She felt that she could, and wanted more than anything to take care of this baby, but They wouldnt allow it. Once her parents finally decided to talk to her, they gave her a choicewell an ultimatum really. They first tried to convince her to have an abortion, it will solve everything, they insisted. When she refused to even talk about it, they then suggested adoption. They told her that they could send her to a special place where there were other girls in trouble like her. She would have the baby and then it would be given to a nice family. Sara kept it as a suggestion, hoping that her parents would eventually come around and let her keep the baby. Then they told her that was it. If she didnt take one of those options, she would be kicked out with out a penny of support. They gave her one-month to decide. Sara knew that she could never live with herself if she had an abortion, it was not even a possibility. She wanted this baby so much and just knew that it was a baby girl. She even named her Megan Renee. She pictured what she would look like. Blond hair and soft blue eyes. The tiny little fingers that would clasp around hers, the little legs that would kick in excitement. She wanted so badly to see her baby girls little face, to hold her in her arms and rock her to sleep. She told her parents she would go to the home, but secretly she was trying to figure out a way to make it work. She knew deep down though that it never would. She had no real money of her own, and she didnt know anyone who would or could take her in. When she was six months along she finally gave up and decided that the best thing for Megan was to find a good home for her. She started to interview potential parents-to-be. She went through eleven couples, and ruled out six right away. Not that they wouldnt make good parents, she just didnt think that they would make the right parents for her baby. She finally narrowed it down to two couples. They were very nice people and had a little boy who was six. They had a little girl also, but she died when she was only four days old. After three miscarriages, they couldnt bare to try any more. They had a beautiful house, and their son Alex was so sweet. Sara knew right away that her baby would be in good hands with this family. The other couple

This is a lab report on Drug Analysis-Thin Layer Chromatography essays

This is a lab report on Drug Analysis-Thin Layer Chromatography essays Objective: To detect the separation and tentative identification of components present in mixtures by using thin layer chromatography. Materials and Methods/Procedures: A thin layer plate was obtained and a baseline was drawn in pencil approximately 1.5 cm from the bottom of the plate. Seven equidistant spots were marked and labeled on the baseline. Six samples were obtained and using a new capillary tube for each sample, a spot of each drug solution was placed on the appropriate mark on the chromatography plate. The spots were allowed to dry, and one drop of the five drug samples were spotted on the mark labeled mixture'. The mark labeled unknown' was spotted with the unknown sample a couple of times. The plate was placed in a prepared solvent chamber', and when the solvent moved up the plate  ¾ of the way, the plate was removed and allowed to dry. The plate was then examined under short wavelength ultraviolet light. Results: After observing the plate, the drug present in the Unknown sample was identified as Phenacetine. The spots observed in the "Mixture" were compared to the spots of each individual drug and it was noted that the unknown #6, identified as Phenacetine, was the only spot to match with the number 7 mixture. Spot #1-caffeine, and spot #5-quinine were noted to be Discussion: When using thin layer chromatography to observe spots of individual drugs it was noted that most of the drugs were not level or were Conclusion: Thin layer chromatography allowed the student to determine what the unknown drug was by running spots of the sample with known drug samples on the same plate, and then comparing the results. This also prevented any uncertainties which could have been caused by variations in ...
