Binary and ternary blends of poly(lactic acid) (PLA), polystyrene (PS) and acrylonitrile-butadiene-styrene (ABS) were prepared using a one-step extrusion process. Rheological and mechanical properties of the prepared blends were determined. Rheological properties were studied using a capillary rheometer, shear rate, shear stress, non-Newtonian index, shear viscosity and flow activation energy w...
High-index oils are critical to the performance of optical electrowetting devices, such as lenses, prisms, and retroreflectors. Herein, the preparation and electrowetting analysis of 1-chloronaphthalene are reported. When 1-chloronaphthalene is mixed with small amounts of an alkane, the following properties can be achieved: refractive index > 1.60, viscosity < 5 cP for rapid switching, operatio...
Hyperviscosity syndrome is usually seen in Waldenstrom macroglobulinemia with the serum viscosity > 4 cP. It commonly manifests as skin or mucosal bleeding, visual abnormalities and neurological symptoms. We describe a case of a 65-year-old man, who presented with chronic exertional chest pain and dyspnea without other manifestation and had hyperviscosity syndrome related to marginal zone lymph...
Abstract The Met Office in the United Kingdom has developed a completely new probabilistic postprocessing system called IMPROVER to operate on outputs from its operational numerical weather prediction (NWP) forecasts and precipitation nowcasts. aim is improve forecast information public other stakeholders while better exploiting current future generations of underpinning kilometer-scale NWP ens...
The present work reported density, viscosity, speed of sound, electrical conductivity and refractive index data of L-alanine in the aqueous solutions of 1-hexyl-3-methylimidazolium ibuprofenate at T= 298.15 K. Using the measured data, partial molar volume of transfer ( ), partial molar isentropic compressibility of transfer ( ), viscosity B-coefficient of transfer (∆traB), ion association const...
Yeast is one of the most important ingredients in bread making and, it may be isolated from local fruits such as sweet oranges a commercial yeast substitute. This research aimed to isolate orange (Citrus sinensis L) that used improver. The method was endophytic isolation on rind and flesh citrus fruits. It identified macroscopically, microscopically analyzed for carbohydrate fermentation, growt...
Abstract Polyethylene terephthalate (PET) is a material developed by industrial manufacturers, but which also abundantly found as recovery in many daily activities. Since it largely used the textile industry, objective of this work to improve flow polyethylene spinning an application using certain polymers produce quality fabrics. The methodology adopted here interpose layers balls form porous ...

Coefficient of friction behavior of gear oils and significance for the meshing process of spur gears
Abstract The mechanical properties of oils are determined using test methods. There standardized methods for determining viscosity and density. characterization transmission oil based on its dynamic alone is not sufficient the physical explanation different levels noise emissions in vehicle transmissions. For this reason, procedure coefficient friction used following to enable a further differe...
Whole blood viscosity issues VII: The correlation with leucocytosis and implication on leukapheresis
BACKGROUND Blood hyperviscosity has been acknowledged to be a complicating factor in polycythaemia and hyperproteinaemia. Hyperleucocytosis has also been implicated in hyperviscosity and may be a basis for therapeutic leukapheresis. AIMS This issue in the series seeks to determine the association and correlation between whole blood viscosity and white blood cell count (WBCC), with a view to a...
