The General Pathology
No full textThe definition of indolent lymphoma implies a lymphoid proliferation characterized, in the majority of the clinical scenarios, by a protracted, chronic course of disease, manageable over time, albeit not definitely curable. From the standpoint of the pathologist in charge of the diagnostic tissue workup, indolent grossly overlaps with so-called low grade, that is, composed of cells resembling the mature, non-blastic counterparts of the immune system, which are lymphocytes, centrocytes, plasma cells, and variants of these. This definition is formally not part of the WHO classification but still influences the diagnostic practice. A notable exception to the rule that links non-blastic morphology with indolent clinical behavior is mantle cell lymphoma, a proliferation of (mostly) small centrocytes, which presents an aggressive clinical behavior in a subset of patients. All these need to be kept in mind by both the hematologist and the pathologist when using the the “indolent” lymphoma
The role of factoring for financing small and medium enterprises
No full textAround the world, factoring is a growing source of external financing for corporations and small and medium-size enterprises (SMEs). What is unique about factoring is that the credit provided by a lender is explicitly linked to the value of a supplier's accounts receivable and not the supplier's overall creditworthiness. Therefore, factoring allows high-risk suppliers to transfer their credit risk to their high-quality buyers. Factoring may be particularly useful in countries with weak judicial enforcement and imperfect records of upholding seniority claims because receivables are sold, rather than collateralized, and factored receivables are not part of the estate of a bankrupt SME. Empirical tests find that factoring is larger in countries with greater economic development and growth and developed credit information bureaus. In addition, the author finds that creditor rights are not related to factoring. The author also discusses reverse factoring, which is a technology that can mitigate the problem of borrowers'informational opacity in business environments with weak information infrastructures if only receivables from high-quality buyers are factored. She illustrates the case of the Nafin reverse factoring program in Mexico and highlights how the use of electronic channels and a supportive legal and regulatory environment can cut costs and provide greater SME services in emerging markets.Banks&Banking Reform,Banking Law,Financial Intermediation,Environmental Economics&Policies,Economic Theory&Research
Commonality of elastic relaxation times in biofilms
No full textBiofilms, sticky conglomerations of microorganisms and extracellular polymers, are among the Earth's most common life forms. One component for their survival is an ability to withstand external mechanical stress. Measurements indicate that biofilm elastic relaxation times are approximately the same (about 18 min) over a wide sample of biofilms though other material properties vary significantly. A possible survival significance of this time scale is that it is the shortest period over which a biofilm can mount a phenotypic response to transient mechanical stress

Molecularly Imprinted Nanospheres by Nonaqueous Emulsion Polymerization
No full textThe preparation of nanosized, molecularly imprinted polymer particles by nonaqueous emulsion polymerization is presented. Monodisperse cross-linked polymer nanospheres with a diameter of around 100 nm were synthesized using a standard monomer mixture of methacrylic acid and ethylene dimethacrylate, containing (+/-)-propranolol as a template. The rebinding efficiency of the resulting particles was determined by batch rebinding tests and isothermal titration calorimetry (ITC). The results indicate that the proposed imprinting process under nonaqueous conditions lead to particles with an enhanced capacity of template rebinding compared to both nonimprinted ones and to particles obtained by more conventional emulsion polymerization in water
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Does acyclovir prevent the diagnosis of herpes encephalitis?
No full textAcyclovir is a promising new anti-viral drug with proven efficacy against Herpesvirus simplex (Schaeffer et al 1978). At the recent meeting of The European Federation of Child Neurology Societies (Oxford; September 1981), a participant suggested that such was the efficacy of this drug in eradicating H. simplex infection; in cases of herpes encephalitis treated with it, there might be no immune response to the virus in the central nervous system (CNS). Retrospective cerebrospinal fluid (CSF) antibody assay (MacCallum et al 1974, Klapper et al 1981), which provides noninvasive diagnosis of herpes encephalitis, could therefore be falsely negative.</p
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
