  • Chemical reactions (abiotic reactions) are “classical” chemical reactions that are not mediated by bacteria. They may include reaction processes such as precipitation, hydrolysis, complexation, elimination, substitution etc. that transform chemicals to other chemicals and potentially alter their phase/state (solid, liquid, gas, dissolved). Precipitation is the removal of ions from solution by the formation of insoluble compounds, i.e. a solid-phase precipitate. Hydrolysis is a process of chemical reaction by the addition of water.

  • 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.

  • Reactions and transformations of chemicals. Many chemicals undergo reaction or transformation in the subsurface environment. In contrast to retardation contaminants may be removed, rather than simply slowed down. Reactions of harmful chemicals to yield benign products prior to arrival at a receptor are the ideal, e.g. many toxic hydrocarbons have potential to biodegrade to simple organic acids (of low health concern and themselves potentially degradable), carbon dioxide (bicarbonate) and water. Transformation often causes a deactivation (lowering) of toxicity.

  • The Finnish Higher Education Evaluation Council (FINHEEC) has conducted audits of the quality systems of higher education institutions (HEIs) since 2005. The goal of the audits is to support Finnish HEIs in developing their quality systems to correspond to the European quality assurance principles 1 and to demonstrate that Finland has competent and systematic national quality assurance in place for higher education. Under the Finnish Universities Act and Polytechnics Act, HEIs are responsible for the quality and continuous development of their education and other operations.

  • Lichens have been used to study air pollution chemistry in national parks and forests since the 1980s (Figures 1 and 2). There have also been a few lichen studies on national wildlife refuges. Most of the studies have been floristic studies, reports of baseline concentrations of elements in lichen tissues and, occasionally, trends in these concentrations. Figure 1 shows park and refuge locations with tissue chemistry data. USGS Biological Resources Division maintains a web site listing lichens known from each of the national parks shown on the map (http://www.ies.wisc.

  • Some events may appeal to terrorists for a number of reasons, including an anniversary date, religious holiday, a particular location, the nature of the event, or those who will be included among the participants. Communities can identify terrorist organizations that may be attracted to their event for any number of reasons and can prepare accordingly. Knowledge is an advantage. Know the possible risks that the event poses and the audience that the event will attract.

  • They give sodium tail currents with relative longterm constants (Wright, et al., 1988). At lower doses more suble repetitive behavior is seen (Brodie and Aldridge, 1982). As with type I pyrethroids, the primary action is on the central nervous system, since symptoms correlate well with brain concentrations (Rickard and Brodie, 1985). As might be expected, both classes of parathyroid produce large increases in brain glucose utilization (Cremer et al. 1983).

  • The amount of capitalization required by a bad bank is essentially determined by two factors: operating costs and acquisition costs. When a low price is paid for the acquired troubled assets, this not only minimizes the risk of future losses but also keeps the initial capital requirements of the bad bank low. The source of financing determines whether the government or private sector provides the required start-up funding. The need for liquid funds depends on how the banks being freed of their troubled assets will be “paid.

  • There are no steadfast rules or Department of State regulations that state that an EFM of a diplomat operating a business for the exclusive use of other diplomats is exempt from local business start-up policies, including registration and paying local taxes. However, since both the owner/operator of the business and all clients or customers have diplomatic status, the logical extension would be that this exemption does exist. Still, be careful in making such an assumption.

  • Without a consistent focus on simple, fundamental prospecting and sales activities, any program or cultural change initiative is bound to fail. More than any program workbook, seminar or delivery method, it is the ongoing follow-up, the personal coaching and the manager’s ongoing support that will largely determine the ultimate success of any sales culture transformation and sales training initiative. This has proven to be the winning formula for achieving sustainable results for banks. Now let me explain how we deliver this proven formula. ...

  • The internode of solid bamboo has significantly higher ash, 1% NaOH, alcohol- toluene and hot water solubles than the nodes [Mabilangan et al. 2002]. However, differences between the major chemical composition of node and internode fraction of bamboo are small [Scurlock 2000]; neither the number of nodes nor the length of internode segments would be critical to the utilization of bamboo for energy conversion, chemical production, or as a building material. Fujji et al. [1993] investigated the chemistry of the immature culm of a moso- bamboo (Phyllostachys pubescens Mazel).

  • Farmers have several general concerns about crop insurance voiced by national farm organizations representing a cross-section of American agriculture. The American Farm Bureau Federation (AFBF) and others would like USDA to address shallow losses, which occur when losses are significant for the farmer but not enough to trigger an indemnity. 31 Also, this group and others point out a need to address declines in actual production history (APH), which is used for determining the insurance guarantee.

  • PBgC’s financial assistance is not automatic. a plan must follow certain procedures to obtain financial assistance. First, it must notify PBgC and the plan’s participants that it is insolvent. Second, it must inform participants of their statutorily guaranteed benefit levels. next, it must apply for financial assistance with the PBgC. PBgC must then verify the insolvency and determine the level of financial assistance it will provide. This level depends on the amount of contributions and withdrawal liability payments the plan is receiving, if any.

  • Although health economics provides a useful starting point for such analyses of coverage, the ultimate effect of a mandate is not easily reduced to, and in fact could differ from, the predicted effect of treating penalty amounts as dollar-for-dollar equivalents to subsidies. People can respond to penalties and subsidies differently and in ways that are not considered in standard health economics models.

  • Many of the early compliance models assumed that audits were expensive but that penalties could be imposed at low cost to the enforcing agency once an error had been detected. It is not surprising that those models typically showed that, subject to a fixed-budget constraint, the combination of high penalties and low audit rates was socially optimal (McCubbin, 2004). Those results are sensitive to several underlying assumptions. First, feelings about risk vary from one group to another; younger people, for example, could be less risk-averse than older people are.

  • In this paper we examine whether and how accounting information about a firm manifests in its cost of capital, despite the forces of diversification. We build a model that is consistent with the CAPM and explicitly allows for multiple securities whose cash flows are correlated. We demonstrate that the quality of accounting information can influence the cost of capital, both directly and indirectly. The direct effect occurs because higher quality disclosures affect the firm’s assessed covariances with other firms’ cash flows, which is non-diversifiable.

  • In Internet Explorer 7 and Windows Vista, Microsoft introduced a new browser security feature called “Protected Mode”. According to Microsoft, this mechanism “significantly reduces the ability of an attack [against Internet Explorer] to write, alter or destroy data on the user’s machine”.1,2 A clearer description is that the feature attempts to protect the integrity of the client machine in the event the browser is compromised in an attack and prevent malware from being persisted on the targeted machine.
