The rubber composites with good thermal conductivity contribute to heat dissipation of tires. Graphite filled natural rubber composites were developed in this study to provide good thermal conductivity. Graphite was coated with polyacrylate polymerized by monomers including methyl methacrylate, n-butyl acrylate and acrylic acid. The ratios between a filler and acrylate polymerization emulsion and

Objective　To explore the feasibility of retroviral-mediated Flt 3 ligand (FL) and thrombopoietin (Tpo) genes transferred into and expressed in a bone marrow stromal cell line HFCL by internal ribosome entry site（IRES）sequence. Methods　IRES sequence, FL and Tpo cDNA were recombined with retroviral vector pLXSN by gene recombination technology. The recombinant plasmid was transferred into retrovirus

Recent investigations-of the interaction between DNA and alkyltrimethyl ammonium bromides of various chain lengths are reviewed. Several techniques have been used such as phase map determinations, fluorescence microscopy, and electron microscopy. Dissociation of the DNA-surfactant complexes, by the addition of anionic surfactant, has received special attention. Precipitation maps for DNA-cationic

Cardiopulmonary bypass (CPB) has been shown to be associated with systemic inflammatory response leading to postoperative organ dysfunction. Elucidating the underlying mechanisms and developing protective strategies for the pathophysiological consequences of CPB have been hampered due to the absence of a satisfactory recovery animal model. The purpose of this study was to establish a novel, minima

Background Non-heart-beating donor lung has been a promising source of lung transplantation. Many studies on non-heart-beating donor lungs are based on animal lung transplantation. In this study, we assessed by organ bath the effect of one-hour warm ischemia on the non-heart-beating donor lung in terms of the integrity of contractile and relaxant functions and tissue structures of pulmonic arterie

In order to achieve the goal of sustainable banking, banks such as commercial banks have to adopt proactive strategies for reducing internal operation risks from environmental issues thereby realizing long-term profitability by external financing of environmentally friendly products and services. As a general pathway to sustainable banking, environmental risk management (ERM) is regarded as a prev

As a form of active transport, cycling provides significant health benefits to the elderly. Among voluminous active transport-related literature, few studies have investigated the correlates of the cycling activity of urban elderly. This study explored the effects of individual, household, and built environment attributes on the frequency of cycling trips by urban elderly, with data collected from

The definition of a decision support system(DSS) may be : human-computer interactive software system to solve semi-structured decisional problems for decisional makers with data utilizing, information management, knowledge, as well as model techniques. DSS only provide supporting information about making decision for the decision maker without stipulate the decision itself. Decision is made by hum
