Evaluating analytical

  • As currently taught, the introductory course in analytical chemistry emphasizes quantitative (and sometimes qualitative) methods of analysis coupled with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is more than equilib- rium chemistry and a collection of analytical methods; it is an approach to solving chemical problems. Although discussing different methods is important, that dis- cussion should not come at the expense of other equally important topics.

  • Our pharmaceutical and medical organizations are living organisms need feeding, growth and development to be competitive and can strive to survive otherwise it will degenerate by the tough competition from the surroundings. Quality is a major tool for agile and competitive organization. Quality need to be monitored and to be built into the product so it needs quality control which need highly accurate, precise, sensitive and valid analytical procedures to judge the quality throughout the manufacturing process....

  • Colloid and surface chemistry occupy a paradoxical position among the topics of physical chemistry. These are areas which have traditionally been considered part of physical chemistry and are currently enjoying more widespread application than ever due to their relevance to environmental and biological problems. At the same time, however, colloid and surface chemistry have virtually disappeared from physical chemistry courses. These topics are largely absent from the contemporary general chemistry course as well.

  • Combustion involves change in the chemical state of a substance from a fuel state to a product state via a chemical reaction accompanied by release of heat energy. Design or performance evaluation of equipment also requires knowledge of the rate of change of state. This rate is governed by the laws of thermodynamics and by the empirical sciences of heat and mass transfer, chemical kinetics and fluid dynamics. Theoretical treatment of combustion requires integrated knowledge of these subjects and strong mathematical and numerical skills.

  • This book distils years of work on the mobile telecommunications industry. I became interested in this industry for professional reasons during the mid-1990s, a period when the industry was making the jump from a premium service industry for mostly professional users to a truly mass market. In my capacity as an applied industrial organisation economist, I had the unique opportunity of evaluating the business plans and strategies of a large number of mobile telecommunications firms inside and outside Europe.

  • The committee was tasked to determine the best instrumentation and procedures for measuring BFD (see Box S-1). To do this, it reviewed technical specifications, viewed demonstrations of the operation and use of current and prospective systems, and evaluated factors such as human handling variability, process transparency, and software variability judgment. The committee found that given the current clay variation, a measurement precision (standard deviation) of 0.5 mm is sufficient; instruments featuring greater precision add little practical value to the testing process.

  • The prototypical catalytic reductiveC–Cbond formations, the Fischer-Tropsch reaction [1] and alkene hydroformylation [2], were discovered in 1922 and 1938, respectively [3,4]. These processes, which involve reductive coupling to carbon monoxide, have long been applied to the industrial manufacture of commodity chemicals [5]. Notably, alkene hydroformylation, also known as the oxo-synthesis, has emerged as the largest volume application of homogeneous metal catalysis, accounting for the production of over 7 million metric tons of aldehyde annually.

  • The chemical properties of organics of health concern – hydrophobic and not water soluble - results in a low bioavailability to plants. Plant growth is dependent on the water solubility of nutrients and minerals and water is the transporting vector. Organics with a low water solubility will therefore not be taken up by plants. The presence of organic environmental pollutants, like dioxins and PCBs in agricultural crops is more the result of atmospheric deposition than direct absorption from contaminated soil.

  • When evaluating the pruchase power of the population, additional variables than average income should be considered. In the case of Mexico, for instance, the purchasing power of many younger Mexicans is higher than income statistics might suggest at first sight: Unlike their Central European or North American counterparts, it is not uncommon for young Mexicans to stay in their parents’ home up to (or even beyond) the time when they get married. They thus save considerable amounts of money on rent which then is often spent on consumer goods....

  • MapReduce has been proven as a technique for high-scale data analysis by Internet leaders such as Google and Yahoo. Greenplum gives enterprises the best of both worlds—MapReduce for programmers and SQL for DBAs—and will execute both MapReduce and SQL directly within Greenplum’s Parallel Dataflow Engine (Figure 10), which is at the heart of the database. Greenplum MapReduce enables programmers to run analytics against petabyte-scale datasets stored in and outside of Greenplum Database.

  • The goal of this project is to learn about the visual qualities that can be used to control aesthetics in visualization. Psychologists have identified emotional and cognitive properties believed to underlie the aesthetic judgement of images. Based on this work, I have chosen three visual qualities that appear promising to aesthetics in visualization. I propose to vary these qualities and conduct studies to evaluate the salience of each quality in terms of aesthetics. Statistical analysis will be used to detect any significant changes in aesthetic judgement or related properties.
