  • The Laboratory Gas Burner Tirrill or Bunsen burners provide a ready source of heat in the chemistry laboratory. In general, since chemical reactions proceed faster at elevated temperatures, the use of heat enables the experimenter to accomplish many experiments more quickly than would be possible at room temperature. The burner illustrated in Fig. 1.1 is typical of the burners used in most general chemistry laboratories. Figure 1.1 The Bunsen burner. Hottest part of the flame (800°C) Violet outer cone Pale-blue middle cone Dark-blue inner cone ...

  • The realm of aqueous organometallic catalysis incorporates many more reactions and catalysts than discussed in the preceeding chapters. However, these were not investigated in so much detail as, for instance, hydrogenation or hydroformylation; some of them are mentioned only here and there. An attempt is made to give a representative sample of these studies.

  • In 1932, James Chadwick discovered the neutron, but initially the only sources of neutrons were from the radioactive decay of unstable nuclei. It was not until 1942 when Enrico Fermi constructed the first nuclear reactor in the squash courts beneath the University of Chicago’s Stagg Field, that a controlled and sustained nuclear chain reaction was achieved. After World War II, nuclear reactors became available for civilian research, and in 1945 Ernest Wollan set up a double-crystal diffractometer at ORNL’s Graphite Reactor. This marks the beginning of neutron scattering....

  • It is necessary for concrete structure with mass section to have a rational crack control plan based on analysis of thermal stress from hydration heat. Because mass concrete can cause crack to deteriorate durability of structure. So, this study reports two examples: one is a process to calculate an adiabatic temperature rise and a reaction rate for evaluate thermal stress.

  • Populations in Southeast AsiaandSouthChinahave highfrequencies ofa-thalassemia caused by a-globin gene mutations and/or deletions. This study was designed to find an efficient and simple diagnostic test for the mutations and deletions. A duplex polymerase chain reaction (PCR)/denaturing high-pressure liquid chromatography (DHPLC) was used to detect the mutations and deletions. A blinded study of 110 samples, which included 92 a-thalassemia samples with various genotypes and 18 normal DNA samples, was carried out by the methods.

  • Petroleum mixtures consist primarily of relatively unreactive complex hydrocarbons covering a wide boiling range. Such mixtures are difficult to separate by most analytical techniques. Therefore, the petroleum industry has for many years played a leading role in the development of chromatographic methods of analysis. Since the last book specifically concerned with chromatographic analysis of petroleum appeared 15 years ago, numerous advances have been made including developments in liquid and supercritical fluid chromatography, ...

  • This book presents a critical review of various chromatography techniques for a limited number of processes. Most techniques are illustrated by examples. The processes described are necessarily limited to those which appear to the authors to have the greatest validity and practical use. Wherever possible, we have included recommendations delineating the best techniques for analyzing each sample. Recommended techniques are often illustrated by detailed examples.

  • So you wanna be a hotshot game designer? Well, if you have a basic grasp of Macromedia Flash MX, you can. Unafraid to tackle some of the more complicated aspects of game creation (including physics and trigonometry!), this comprehensive reference covers it all. Macromedia Flash Game Design Demystified starts out with the basics: planning, adapting ActionScript techniques, using introductory Flash game techniques, and more. Then it gets down to the real business of building simple games.

  • Myocarditis is a clinical syndrome characterized by inflammation of myocardium. It can be produced by a myriad of etiologies including infectious, autoimmune, myocardial toxins, hypersensitivity reactions and physical agents. Virtually any infectious agent can produce myocardial inflammation and injury. Human myocarditis is most frequently caused by viral infection. Ongoing viral infection, myocardial destruction, and adverse remodeling can lead to persistent ventricular dysfunction and dilated cardiomyopathy.

  • Few terms have been more commonly used and abused in the scientific literature than nano. However, if one is able to sift through the vast amounts of nano literature, there are also numerous reports that are of both academic and commercial importance. This is particularly true for the field of catalysis in which rapid progress is being made that has transformed this once black art into a science, which is understood on a molecular and even atomic level.

  • Many of the techniques that have been developed have already been used to study the extent and distribution of variation in species gene-pools and to investigate evolutionary and taxonomic relationships among plant populations. With the development of the polymerase chain reaction (PCR) based techniques, in particular, numerous molecular technologies have been, and still are being, developed, which can be used for the detection, characterization, and evaluation of genetic diversity in plant populations.

  • Fine-Needle Aspiration Cytology/ Biopsy (FNAC/FNAB) is now a widely accepted diagnostic procedure, which has largely replaced open biopsy. This method is applicable to lesions that are easily palpable, for example swellings in Thyroid, Breast, superficial Lymph node etc. Imaging techniques, mainly ultra-sonography and computed tomography, offer an opportunity for guided FNAC of deeper structures. The practice of diagnostic cytology needs proper training of the laboratory personnel including cytopathologist, cytotechnologist and cytotechnician.

  • Our work is almost exclusively with banks and financial services companies in local markets, in western states markets, nationally and even abroad. We see what works, where it works, and why it works in one market, and maybe not in others. When we find anything new that has the potential to work better than our baseline programs, we incorporate the technique into our toolkit of tactics and menu of options for participants. We do not represent any particular sales system and are not bound to represent any particular sales management company. Rather than being tied...
