the abrasive flow machining technique uses a self-deforming tool, an abrasive laden media that is passed back and forth in the passage geometry of the hollow workpiece with the assistance of two hydraulically operated cylinders placed opposite to each other. the material is removed by abrasion generating finer surfaces in the area where flow is restricted. but this method has a low material rem...

Cereal Chem. 83(2):121–126 In dry-grind processing to produce ethanol from corn, unfermented solids are removed from ethanol by distillation and dried to produce distillers dried grains with solubles (DDGS), an animal food. Fouling of thin stillage evaporators has been identified as an important energy consumption issue in dry-grind facilities. Using an annular fouling apparatus, four batches o...

OBJECTIVES Consumption of alcoholic beverages reduces the risk of coronary artery disease (CAD), and epidemiological studies have shown that ethanol per se is protective. However, the mechanism by which ethanol exerts protection is not fully known. Ethanol can stimulate neuropeptide-containing primary sensory neurons via the activation of transient receptor potential vanilloid 1 (TRPV1). Here, ...

Effects of recipient oocyte activation methods on the development of nuclear transfer (NT) embryos were investigated. In Exp. 1, cell-cycle phase of serum-starved bovine cumulus cells was examined by flow cytometry. Majority (95.5%) of medium-sized (16-20 microm) cells that made up 56% of total cells was at the G0/G1 phase. NT embryos were constructed by electric fusion with the medium-sized se...

venous malformations are the most common form of symptomatic vascular malformations. vm s could classify into low-flow lesions (vms) and high-flow lesions (avms). for low-flow venous lesions, direct percutaneous puncture with injection of sclerosing agents (sclerotherapy) has been described as a successful therapy. in this article, we want to introduce a patient who treated with ethanol sclerot...

We investigated the acute hemodynamic effects of ethanol microinjection into brain areas known to influence cardiovascular function and reflexes. In chloralose-anesthetized rats, ethanol had no effect on baseline mean arterial pressure, heart rate, or sympathetic efferent discharge when microinjected into the nucleus tractus solitarius, the dorsal motor nucleus of the vagus, the rostral ventrol...

We analyzed the effects of several factors on the serum ethanol levels after alcohol sclerotherapy in the arteriovenous malformations (AVMs) retrospectively. Blood ethanol level, amounts of given alcohol, location of lesions, methods of flow control, and Doppler resistive index (RI) were analyzed. The results of linear regression analysis showed that the amount of alcohol administered was the p...

We have recently identified a homogeneous population of gamma-aminobutyric acid (GABA)-containing neurons in the ventral tegmental area (VTA), an area implicated in the reinforcing properties of alcohol. We evaluated the effects of local and systemic ethanol on VTA GABA neuron spontaneous activity in ethanol naive and chronically treated freely behaving rats and in anesthetized rats. In freely ...

An isolated perfused ra t liver preparation has been developed to aid the study of the mechanisms underlying the secretion of bile and the cholestatic actions of two naturally occurring agents, icterogenin and sporidesmin. The perfused liver produced bile for 3-5 h a t a steady rate slightly above tha t observed in intact rats possessing external biliary cannulae. During this period of perfusio...

changes of hydrodynamic parameters in microchannel branches affect the suspended biological samples in blood. to prevent denaturation and hemolysis, we have numerically investigated the effect of divergence angle on shear rate and velocity at branch entrance (discharge rate), under electroosmotic flow. in such flow, hydrodynamic properties are also affected by zeta potential at the microchannel...
