  • The synthesis and characterization of activated carbons (ACs) obtained from lignocellulosic precursors is a topic widely studied by a number of researchers worldwide. In the last decades, an increase has been observed in the number of publications related to the synthesis, modification, characterization and application of ACs obtained from lignocellulosic materials. Particularly, the applications of these carbons are primarily focused in the removal of several inorganic and organic pollutants from water and wastewaters....

  • Using the gradient method, element concentrations within the lichen are usually observed to increase as the distance to the suspected source decreases. Gough and Erdman (1977) used linear regression to evaluate the relationship between distance from a coal fired power plant and metal levels in Xanthoparmelia chlorochroa. However, as Puckett (1988) points out, concentrations of many elements will not reach zero at large distances from pollution sources because they have essential nutritional roles or are normal components of the lichen when growing in its natural environment.

  • The purpose of this paper is to introduce the principles of GPS theory, and to provide a background for more advanced material. With that in mind, some of the theoretical treatment has been simplified to provide a starting point for a mathematically literate user of GPS who wishes to understand how GPS works, and to get a basic grasp of GPS theory and terminology.

  • Following demonstration of activity in animal models, conventional chemotherapeutic agents are further evaluated to define an optimal schedule of administration and arrive at a drug formulation designed for a given route and schedule. Safety testing in two species on an analogous schedule of administration defines the starting dose for a phase I trial in humans. This is established as a fraction, usually one-sixth to one-tenth, of the dose just causing easily reversible toxicity in the more sensitive animal species.

  • Cisplatin was discovered fortuitously by observing that bacteria present in electrolysis solutions could not divide. Only the cis diamine configuration is active as an antitumor agent. It is hypothesized that in the intracellular environment, a chloride is lost from each position, being replaced by a water molecule. The resulting positively charged species is an efficient bifunctional interactor with DNA, forming Pt-based cross-links.

  • Pemetrexed is a novel folate-directed antimetabolite. It is "multitargeted" in that it inhibits the activity of several enzymes, including thymidylate synthetase, dihydrofolate reductase, and glycinamide ribonucleotide formyltransferase, thereby affecting the synthesis of both purine and pyrimidine nucleic acid precursors. To avoid significant toxicity to the normal tissues, patients receiving pemetrexed should also receive low-dose folate and vitamin B12 supplementation.

  • Education of the patient is a critical part of treating tuberculosis. The health worker must communicate with a patient clearly and supportively from the time of diagnosis, throughout the long treatment process, and until the patient is cured. The patient’s family will also need information, advice, and support. At the time of diagnosis, patients need basic information about tuberculosis and how it is spread. They may be afraid and need reassurance that TB can be cured. They need an explanation of the treatment process and the necessity of directly observed treatment.

  • Under these circumstances, a mode of treatment which promises a decrease in the number of victims, from the experience of a quarter of a century, and a score of epidemics of different characters, cannot but be received with pleasure by the public. I have treated scarlet-fever hydriatically for twenty-one years, and out of several hundred cases never lost a patient, except one who died of typhus during an epidemy of scarlatina; and my observations, during twenty-five years, of the practice of other physicians of the same school, present a result about as favorable as my own....

  • In consequence of the extreme prevalence of Scrofulous, Scorbutic, and Cancerous Diseases, and the ignorance which exists on the part of the public, as to their causes, symptoms, and nature, I have been induced to reprint my observations on those subjects, and to send forth an Eighth Edition for the information of the afflicted.

  • The surface treatment by physical method of jute fiber using air plasma was investigated. Fiber was treated by the atmospheric plasma with various conditions of power 50W and different treatment times (from 1 min to 7 min). After treatment, the characteristics of fiber changed remarkably and fiber surface observed by SEM analyze showed a better morphology for adhesion. The result showed that tensile strength and Young’s modulus of jute fiber were slightly improved, however there was a remarkable improvement interface adhesion between fibers and polypropylene (PP) resin.

  • The rst seven variables contain information about the general state of the economy and help to identify monetary policy and capital inows shocks. The model includes both short-term and long-term interest rates. In our sample of countries short-term interest rates are largely controlled by central banks. Using movements in nominal short rates to identify monetary policy shocks is standard in VARs that study monetary policy (see eg Christiano et al (1999)). Long-term interest rates, on the other hand, tend to be driven by nancial market outcomes.

  • The M-F model is scanty in that it only describes a single country and contains no representation of how the rest of the world responds to, and interacts with, what it does. And the logical framework of M-F is impoverished in that (like the IS-LM model itself), while “the money supply” plays a key role, money has no accounting relationship to any other variable. The model also contains no explicit analysis of what happens when either goods and services or financial assets are traded between countries.

  • A second way to define power is in terms of a relationship in which one actor is observed to attempt to influence another directly and succeeds. This is sometimes called “actualized” power. The attempt to influence results from differing preferences over outcomes, and the attempt is successful if the attempt of actor A to influence actor B results in an outcome preferred by A.

While there are many excellent textbooks in psychometric theory and its application to large-scale standardized testing programs and many educational measurement and assessment books designed for elementary and secondary teachers and graduate students in education and psychology, none of these books is entirely appropriate for the specialized educational and assessment requirements of the health professions.

  • There is an urgent need to develop new innovative therapies for the control of advanced cancer. The combination of antigen-specific immunotherapy with the employment of immunomodulatory agents has emerged as a potentially plausible approach for the control of advanced cancer. Methods: In the current study, we explored the combination of the DNA vaccine encoding calreticulin (CRT) linked to human papillomavirus type 16 (HPV-16) E7 antigen (CRT/E7) with the TLR7 agonist imiquimod for their ability to generate E7-specific immune responses and antitumor effects in tumor-bearing mice.

  • The presence of amnesia (which in psychoanalytic theories is posited to have the role of covering the unfortunate past) might, however, pose a significant challenge to clinicians trying to identify the precipitating stressful events. Furthermore some cases of dissociative (psychogenic) amnesia did not occur as a result of an objective major psychological stressor, but were recorded after a seemingly objective minor stress (Staniloiu et al., 2009).

  • A surge in expenditure after payday could also reflect stockpiling of durable goods. Households might try to minimize transaction costs of shopping by buying all of their durable goods in one large shopping trip. Given the presence of binding credit constraints, and even a slight degree of impatience, households could choose to time this large shopping trip at the beginning of each pay period.

  • In the spring of 2007, TerraChoice sent research teams into six category-leading big box stores with instructions to record every product-based environmental claim they observed. We instructed the teams that, for each environmental claim, they should identify the product, the nature of the claim, any supporting information, and any references offered for further information. After recording 1,753 environmental claims on 1,018 products (refer to Appendix A), we tested the claims against current best practices in environmental marketing.
