To determine the effect of varying the duration of electrocardiographic recording on the detection of high premature ventricular complex (PVC) rates (30 or more PVCs/hour) and/or complex PVCs (multiform PVCs, couplets or runs) in survivors of myocardial infarction, we evaluated 175 24-hour ECG tapes with such arrhythmias for their occurrences detected in the first 1, 2, 6, 12 and 18 hours of th...

The tunneling ability of the Formosan subterranean termite Coptotermes formosanus Shiraki through a cellulose insulation material containing11.1% boric acid was tested in choice and nochoice bioassays. We examined tunneling behavior and mortality of termites exposed to treated and untreated insulation material in miniature simulated wall voids. In a choice test termites tunneled through untreat...

Transport between the trans-Golgi network (TGN) and late endosome represents a conserved, clathrin-dependent sorting event that separates lysosomal from secretory cargo molecules and is also required for localization of integral membrane proteins to the TGN. Previously, we reported a cell-free reaction that reconstitutes transport from the yeast TGN to the late endosome/prevacuolar compartment ...

This study examined whether an aqueous solution that contained 18 organic chemicals that are either solvents or good swelling agents of PVC are able to cause softening when combined in a solution, with each solute at an activity of 0.05. This activity was selected because there is no evidence that an individual organic solute with an activity of 0.05 can soften PVC. However, we found that this ...

Golgi-mediated transport to the lytic vacuole involves passage through the prevacuolar compartment (PVC), but little is known about how vacuolar proteins exit the PVC. We show that this last step is inhibited by overexpression of Arabidopsis thaliana syntaxin PEP12/SYP21, causing an accumulation of soluble and membrane cargo and the plant vacuolar sorting receptor BP80 in the PVC. Anterograde t...

Buildings account for a significant portion of a nation’s total energy consumption. To meet the global demand for greater energy efficiency, many countries are drastically strengthening insulation regulations for buildings. Thus, dramatically thicker wall insulation may be required, which can adversely affect the value of a building by reducing its effective floor area. Hence, high-performance ...

Thermooxidative degradation of poly(vinyl chloride) (PVC) is inevitable during processing of PVC. Recycling of this polymer requires reprocessing in most of the cases, and due to the low thermal stability of PVC, it is of paramount importance to reveal the effect of thermooxidation on the thermal stability of this commercially important polymer. However, detailed systematic investigations are l...

This study is researching a synthesis of an automatic control system for maintaining the temperature petroleum products during storage in tanks. A new approach construction has been developed this research. It helps to get rid disadvantages existing methods heating Developed built on basis feedforward principle. The object tank insulation layer, considered as with distributed parameters, which ...

Submit Manuscript | http://medcraveonline.com PVC has significant defects due to its quick decomposition at temperature higher than 130°C [3-5]. This process results in a significant change in color, reducing the mechanical properties and the generated HCl exacerbates the decomposition of PVC, so the usage of PVC thermal stabilizers is inevitable [4,6]. Our group had synthesized pentaerythritol...
