...Nearly eleven times as large as the Burj Khalifa, the world’s tallest manmade structure, Mount Everest looms over the rest of the world with the spectacular height of 29,029 feet. Imagine how amazing it feels to stand on the summit of this mountain, the highest elevation on Earth that any human can climb to, peering over the rest of the beautiful world. The author of Into Thin Air: A Personal Account of the Mount Everest Disaster, Jon Krakauer, experiences this, but he has determined that it is by far the worst incident of his entire life. Krakauer ascends the mountain with well-respected and world-famous mountaineer Rob Hall’s team. Several of the people on Hall’s team, including Krakauer, successfully reach the summit, but descending proves...

University, Khandwa Road, Indore 452017, India Received 16 March 2001; accepted 25 June 2001 Abstract An experimental dryer was developed for determining the kinetics of black tea drying. Drying characteristics of tea were examined using heated ambient air for the temperature range 80–120°C and air flow velocity range 0.25–0.65 m/s. The data of sample weight, dry- and wet-bulb temperatures and air velocity of the drying air were recorded continuously during each test. The drying data were then fitted to the different semi-theoretical models such as Lewis, Page, modified Page, two-term and Henderson and Pabis models, based on the ratios of the difference between the initial and final moisture contents and the equilibrium moisture content. The Lewis model gave better predictions than other models, and satisfactorily described the thin-layer drying characteristics of black tea particles. The effective diffusivity varied from 1:14 Â 10À11 to 2:98 Â 10À11 m2 /s over the temperature range. The temperature dependence of the diffusivity coefficient was described by the Arrhenius-type relationship. The activation...

...Fe(OH)2 is technically an equilibrium process (all electrochemical processes are) the value of Kc is very large (>1099 at 298 K) and left unchecked it will go to completion. But the rate is relatively slow under normal atmospheric conditions and so it is still possible to manipulate the equilibrium somewhat by changing appropriate factors. The rates of corrosion reactions--and presumably their mechanisms--vary widely. Factors which influence the progress of the net reaction in the first step of the oxidation of iron may have an effect on the overall rate. The nature of the oxide product is also very important in affecting the extent of the corrosion. For example, aluminum is a very active metal, but its oxide, Al2O3, is very dense and forms a thin protective layer on the metal which discourages further corrosion. In contrast, iron rust (hydrated forms of Fe2O3 such as reddish-brown Fe(OH)3) is typically flaky and easily crumbles off to continually expose fresh metal for reaction. Although the mechanism for corrosion is not always well understood, it is clear how to prevent it. The surface of the metal must be protected from contact with oxygen. Paints, oils and other coatings are often used for this purpose. But it is...

...¨ ¨ Julich, Germany and 2Chemical Engineering Department, University of Patras, GR 265 00 Patras, Greece ¨ 1 Abstract—For solid oxide fuel cells (SOFCs) operating at intermediate temperatures the adjacency of the state-of-the-art yttria-stabilized zirconia (YSZ) electrolyte with ceria-based materials to both anodic and cathodic sides is regarded as crucial for the effectiveness of the cell. Solid-state reaction, however, and interdiffusion phenomena between YSZ and ceria-based materials can cause degradation of the electrolyte. When a gadolinia-doped-ceria (GDC) layer is used to protect YSZ against interaction with Co-containing cathodes, an unfavorable solid state reaction at the YSZ–GDC interface can be efficiently suppressed when a thin ( 1 µm thick) interlayer with nominal composition of Ce0.43Zr0.43Gd0.10Y0.04O1.93 is incorporated at the interface. When ceria is to be employed at the electrolyte–anode interface to reduce polarization losses, use of a ceria–40% vol Ni cermet is recommended, since suppression of the reactivity between YSZ and ceria can also be achieved in the presence of Ni. © 2000 Acta Metallurgica Inc.

...MGT 1203 International Trade Management Case I Overview and Rubric Breezy Air Filters - Redefining the Business Coming up for air Breezy Auto Parts has been supplying the North American automobile industry with carburetors and air filters for more than half a century. With revenues of about $100 million a year, it is a significant player in the parts industry. Initially, it supplied carburetors and filters to each of the Big Three domestic manufacturers. When foreign car manufacturers entered North America to set up manufacturing operations, Breezy also developed relationships with the newcomers. It redesigned some of its products to fit the foreign models. It also introduced electronic data interchange (EDI) to support just-in-time deliveries to all of its customers. As a result, it successfully realized its original corporate vision of becoming North America’s leading supplier of carburetors and air filters, a position it has occupied ever since. For the past 30 years, Breezy has counted on steady customers and steady revenues. The past two years, however, have raised significant concerns about the company’s future. The price of crude oil has been soaring as have gas prices at the pump. There have been temporary dips in price, but the overall trend is unmistakable: it will be far more expensive to drive in the future. As a result, car sales have flattened and in some cases declined. This is especially true of the big gas guzzling SUVs upon which the...

...for detecting alkaloids, in particular nicotine, from Nicotiana rustica tobacco seedlings up to 2 mm in length has been developed. Growing tissue is applied (squashed) directly onto silica gel plates for thin-layer chromotographic analysis. The sensitivity of this method permits the detection of quantities of nicotine as small as 0.4 microgram. INTRODUCTION During the course of our study on the chemical patterns of plant growth and development (Peters et al., 1972), it was necessary to use rapid procedures to analyze chemical contents of growing tissues. The present study deals with the development of a procedure for the rapid detection of the alkaloids. The histochemical detection of alkaloids in growing tissues, as demonstrated by others (Chaze, 1932; James, 1950), is based on the reaction with iodine in potassium iodide solution. These methods are complicated by the presence of carbohydrates and proteins, which also react positively to iodine in potassium iodide solution. James (1946) was able to overcome the difficulty of liberating alkaloids from denatured proteins by blotting the tissue on filter paper prior to other treatment; however, the blotting procedure results in partial loss of cellular alkaloid content. A tedious solvent extraction procedure followed by thin-layer chromatography has been used by Speake et al. (1964). Other workers have used the reliable but time-consuming steam-distillation extraction technique (Solt, 1957; Brown and Byerrum, 1952). This paper...

...when the air is warm and releases heat when the air is cool. Because it is a fluid, the ocean diffuses the effects of a temperature change for great distances via vertical mixing and convective movements. The solid land cannot, so the sun's heat penetrates only the thin, upper crust. One consequence of the ocean's ability to absorb more heat is that when an area of ocean becomes warmer or cooler than usual, it takes much longer for that area to revert to "normal" than it would for a land area. This also explains why "maritime" climates tend to be less extreme than "continental" ones, with smaller day-night and winter-summer differences. 3. Clouds act as an insulator to trap in the heat. When there are no clouds, the heat can leave the earth more quickly. 4. An ordinary fan does not cool the air directly. It actually warms the air slightly, because the motor used to power the fan will exhaust some heat into the air, and the increase in average kinetic energy of the air molecules caused by the fan blades pushing them means the air temperature increases slightly. The reason for using the fan is that it keeps air moving. The human body warms the air immediately around it, assuming the air is initially cooler than the body. If that warmed air stays in contact with the body, then the body will lose little further heat after the air is warmed. The fan, by circulating the air, removes the heated air from close to the body and replaces it with cooler air. Likewise...

...teeth? Hypothesis and Explanation * If an egg shell is put in cola, then the egg shell will become discolored and thin. It will be broken down because of the sugars, carbonation, and acid. The cola will have a similareffect on human teeth as it does on the egg shells. My Interesting Facts * Soda discolors our teeth. * Soda wears away the enamel on your teeth and makes them weak. * The Coca Cola left a film in the jar. * Phosphoric acid is also found in milk, meats, and grains. * Phosphoric acid has very little effect on our teeth. * The saliva in our mouth helps neutralize the acid in the soda, therefore acid has littleeffect on our teeth. Experiment: Materials Needed and Instructions for the Experiment * Materials: * 5 egg shells. Wash and cleaned of the egg whites and yokes * 5 mason jars with lids 5 cola brands. * Coca Cola * Dr. Pepper * Pepsi * Diet Coke * Big K Cola * Masking tape to label each jar. * Log book. This is how I conducted the experiment. I began by pouring one can of each of the sodas into each of the mason jars. Then I had my mom crack five eggsand wash out the egg whites and yokes. I then placed each of the shells into each of the five colas. I put a lid on each of the jars to help keep out any extra germs in the air. I then daily opened the jars and carefully and observed each of the egg shells to look for changes in their colors...

...via a metalloimine intermediate. A sample Grignard reaction mechanism can be seen in Figure 1 of a Grignard reagent being prepared with an alkyl bromide and later reacted with a formaldehyde to produce a primary alcohol. The purpose of this lab was to form 1-phenyl-3-buten-1-ol using a Grignard reaction. The Grignard reactant was produced from Zinc and Allyl Bromide which was then reacted to Benzaldehyde. The formation of the final product will be confirmed using a Thin Layer Chromatography, TLC, of the product and Benzaldehyde and an IR analysis of the product. Abstract In reactions involving Grignard reagents, it is important to exclude water and air, which rapidly destroy the reagent by protonolysis or oxidation. Since most Grignard reactions are conducted in anhydrous diethyl ether or tetrahydrofuran, THF, side-reactions with air are limited by the protective blanket provided by solvent vapors. Small-scale or quantitative preparations should be conducted under nitrogen or argon atmospheres, using air-free techniques. In our lab, we utilize a procedure...

...and Recommendation Sealed Air has seen new competitors enter the protective packaging market industry producing uncoated bubble at a lower cost by employing a cheaper more efficient production method. We believe the entrance of this new competition will have a significant impact on the sustainability of Sealed Air potentially reducing sales by 55% and eliminating 40% of 1980 EBIT (see exhibit for backup). Given the significant impact we feel Sealed Air must employ a defensive strategy and start production of uncoated bubbles. Sealed Air can use a current production process which would allow them to effectively compete with the new competition requiring no additional capital. Company Analysis Sealed Air produces 2 main products (see exhibit for product breakdown, sales and market share) and also licenses to Astro its patented technology to produce coated and uncoated bubbles. Sealed Air’s core strengths include 1) 1st to market and leader in R&D, innovation and technical development, 2) best trained sales staff in industry, and 3) premium pricing position 4) patented manufacturing process for sealed bubbles. Significant weaknesses include 1) limited resources, 2) having premium products aimed at niche segments of the protective packaging customers, 2) lots of cheap competition and lack of easily demonstrable universal superiority confusing end users. Deciding to start manufacturing uncoated bubbles does not significantly leverage Sealed Air core competencies and is...

...by anorexia nervosa, and they are all serious health issues. Sufferers of AN will get anxiety and have an excessive fear of being fat and putting on weight. However, the opposite happens as they lose weight as a consequence of starving themselves. If their weight drops below 85% of their average weight then they will be diagnosed with AN. They have body image distortion and see themselves as fat, rather than their real image, which is bad for their self esteem and extends their disorder. Amenorrhoea occurs and after 3 months, it is a clinical characteristic of anorexia, because the lack of nutrition means your body wouldn't be prepared to provide for a baby to it stops the menstrual cycle. The media is full of thin models and air brushed photographs which portrays thin as the 'perfect' body image. Adolescents with low self-esteem- particularly females- are largely influenced by this and compare themselves to the images of models and celebrities (Jones and Buckingham 2005). This can lead to girls losing weight to reach the 'perfect' image that their idols have. This is supported by Becker (2002) who studied teenage girls from Fiji and found that after the introduction of T.V. in 1995, the girls stated that they wanted to have the figures of the actresses and lose weight. Not only does it show media effects, but it shows it is applicable to other cultures who are usually less exposed to media. However it has been found that giving people awareness and instructional intervention...
