Ton-exchange resins are used repeatedly in a cyclic manner over many years, and deterioration of both physical and chemical properties can be anticipated. Comparison of the properties of used resin with those of new resin is helpfiil to learning more about the nature and cause of deterioration (12). Corrective action frequendy extends the life of the resin. Comparison of properties must always be made with the resin in the same ionic form. [Pg.376]

While not every employee will be interested in the PSM system as a whole, preferring to focus on individual tasks and requirements, it s a good idea to offer the opportunity to learn more. You may find that performance improves as people understand how what they are doing affects other parts of the system and business operations as a whole. [Pg.171]

Carnot soon realized that he did not have the temperament of a soldier and in 1818 left the army. After leaving the army Carnot took up residence in his father s former Paris apartment, and was presumably supported by his family whiile he attended classes at Sorbonne, the College de France, and the Conservatoire des Arts et Metiers. He also frequently visited factories and workshops, both to see steam engines actually in use, and to learn more about the economics of such industrial use of energy. There were rumors that he did at least on a lew occasions receive some consultant s fees for his advise, but there was no clear documentary evidence of this. In 1827 he returned to active militaiy seiwice with the rank of captain, but this lasted only a little more than a year. He resigned in 1828 and died of cholera four years later in Paris. [Pg.219]

The development of particle accelerators grew out of the discovery of radioactivity in uranium by Henri Becquerel in Paris in 1896. Some years later, due to the work of Ernest Rutherford and others, it was found that the radioactivity discovered by Becquerel was the emission o particles with kinetic energies o several MeV from uranium nuclei. Research using the emitted particles began shortly thereafter. It was soon realized that if scientists were to learn more about the properties of subatomic particles, they had to be accelerated to energies greater than those attained in natural radioactivity. [Pg.936]

We will not enlarge on the environment potential of biotechnology any further at this stage. We will, however, raise some environmental issues in later section of this text If you would like to learn more, we recommend the BIOTOL text "Biotechnological Innovations in Environmental and Eneigy Management". [Pg.8]

We will now deal with quite sophisticated issues concerning reactor design and performance. Although we deal with these in a sympathetic manner, you may find it useful to refresh your knowledge by reading more about bioreactors. The BIOTOL series offers opportunities to learn more about fermentors. [Pg.94]

We proposed to study diet and health by combining bone chemistry and histomorphometry. Diet would be determined by analysis of stable isotopes of carbon and nitrogen in bone protein and some preserved hair. In addition, trace elements would be quantitatively analyzed in preserved bone mineral. Abonyi (1993) participated in the study by reconstructing the diet from historical sources and analyzing various foods. Having analyzed human tissues for stable isotopes and trace elements, and foods for the same variables, we hoped to learn more about 19th century diet in southern Ontario, and at the same time, learn more about paleodiet reconstruction. [Pg.3]

The system used in the simulations usually consists of solid walls and lubricant molecules, but the specific arrangement of the system depends on the problem under investigation. In early studies, hard spherical molecules, interacting with each other through the Lennard-Jones (L-J) potential, were adopted to model the lubricant [27], but recently we tend to take more realistic models for describing the lubricant molecules. The alkane molecules with flexible linear chains [28,29] and bead-spring chains [7,30] are the examples for the most commonly used molecular architectures. The inter- and intra-molecular potentials, as well as the interactions between the lubricant molecule and solid wall, have to be properly defined in order to get reliable results. Readers who intend to learn more about the specific techniques of the simulations are referred to Refs. [27-29]. [Pg.86]

The process by which cells take up large molecules is called endocytosis. Some of these molecules (eg, polysaccharides, proteins, and polynucleotides), when hydrolyzed inside the cell, yield nutrients. Endocytosis provides a mechanism for regulating the content of certain membrane components, hormone receptors being a case in point. Endocytosis can be used to learn more about how cells function. DNA from one cell type can be used to transfect a different cell and alter the latter s function or phenotype. A specific gene is often employed in these experiments, and this provides a unique way to smdy and analyze the regulation of that gene. DNA transfection depends upon endocytosis endocy-... [Pg.428]

Butadiene, used in the chemical industiy as a precursor of synthetic mbber, is a hydrocarbon with the formula C4 Hg. (See Box 13-1 to learn more about the mbber industry.) The Lewis stmcture of butadiene contains two double bonds on sequential pairs of carbon atoms. The chemistry of butadiene, including its ability to form mbber, can be traced to the delocalized electrons in the tt system of the molecule. [Pg.713]

From the above it is obvious that merely the magnitude of the numerical value of Fj and the shape of the plot of Fj versus ([Ac]/[I])o do not make it possible to classify induced reactions correctly. It is necessary to learn more about the mechanism of induced reactions. The schemes presented show clearly that a genuine coupled reaction can be regarded as an open-chain, and an induced catalysis as a closed-chain reaction. However, these limiting types of reactions occur only rarely. [Pg.517]

It has taken time for methods to be developed that meet the desire of microbial ecologists to learn more about carbon flow and microbial communities in natural environments. In recent years techniques have developed at considerable speed that offer the potential to answer some of the commonly asked questions. Use of C techniques for measuring carbon flow is one example. While questions still remain about the interpretation and relevance of some modern methods regarding the real makeup and interactions in mixed populations, there is no doubt that the use of biochemical or molecular signatures provides the best opportunity to advance our knowledge in this area. [Pg.396]

Chemistry is the science of matter, its properties, and changes. In your classroom work in chemistry, you will learn a great deal of the information that has been gathered by scientists about matter. But, chemistry is not just information. It is also a process for finding out more about matter and its changes. Laboratory activities are the primary means that chemists use to learn more about matter. The activities in the Laboratory Manual require that you form and test hypotheses, measure and record data and observations, analyze those data, and draw conclusions based on those data and your knowledge of chemistry. These processes are the same as those used by professional chemists and all other scientists. [Pg.216]

In other cases, clinical information is incomplete. One goal of this paper is to suggest some areas where clinicians and clinical researchers might focus their attention to learn more about the implications of PCP abuse. [Pg.161]

You should read Technical Support Note TS-230 Dealing with Numeric Representation Error in SAS Applications to learn more about SAS floating-point numbers and storage precision in SAS. Another good resource for rounding issues is Ron Cody s SAS Functions by Example (SAS Press, 2004). In short, whenever you perform comparisons on numbers that are not integers, you should consider using the ROUND function. [Pg.118]

Located on the outskirts of big cities, coal gas factories produced enormous amounts of pollutants, particularly ammonia-rich water and coal tar. Some of the coal tar was used to make pitch to waterproof ships, roofs, and rope. Some was turned into creosote for preserving wooden railway ties, used by the millions during the railroad boom of the 1840s. But Europe did not have enough roofs, ships, and railroads to absorb all the coal tar that was being produced, so most of it was dumped, often into rivers. Hofmann was eager to learn more about its composition and find uses for it. [Pg.17]

In order to learn more about the photocrosslinking process, we synthesized 1,1-bis(trimethylsiloxy)-1-phenyl(trimethyl)disilane (5) as a model compound and examined its photochemical behavior in solutions. Compound 5 could readily be prepared by cohydrolysis of 1,1-dichloro-1-phenyl(trimethyl)disilane with a large excess of chloro-trimethylsilane in high yield. [Pg.211]
