Drilling is an hole making process in metal cutting operation performed by extrusion which finds wide application in various industries for manufacturing components using metals and non metals. This process is applied widely in assembly of components or elements, where processing challenges are severe issue such as to maintain surface integrity, ovality, machining time, Metal Removal Rate etc.,...

The effects of hypertonic saline solution (HSS) have been shown in several animal models of ischemia and shock. Literature has shown potential benefits of HSS modulating inflammatory response after sepsis in an animal model. We studied the HSS effects in sepsis through cecal ligation and puncture (CLP) in Balb-C mice. Groups studied: 1- CLP without treatment (CLP-C); 2- CLP treated with normal ...

BACKGROUND Flow-mediated vasodilation (FMD) of the brachial artery has been used for the assessment of endothelial function. Considering the mechanism underlying the vasodilatory response of the brachial artery to reactive hyperemia, hyperemic shear stress (HSS), a stimulus for FMD; nitroglycerine-induced vasodilation (NID), an index of endothelium-independent vasodilation; and baseline brachia...

OBJECTIVES To investigate the effect of a seashell protein Haishengsu (HSS), an extract from a shellfish Tegillarca granosa, on cell growth and the expression of apoptosis genes in leukemia K562 cells. METHODS Cultured K562 cells were treated with HSS at various concentrations (10-40 mg/L). The cell cycle, cell growth and the expression of apoptosis suppressor gene bcl-2 and apoptosis promoti...

BACKGROUND Thyrotoxicosis is a common disease resulting from an excess of thyroid hormones, which affects many organ systems. The clinical symptoms and signs are relatively nonspecific and can vary depending on age, sex, comorbidities, and the duration and cause of the disease. Several symptom rating scales have been developed in an attempt to assess these symptoms objectively and have been app...

Although the potential pathogenesis of nonalcoholic fatty liver disease (NAFLD) is unclear, increasing evidence indicates that endoplasmic reticulum (ER) stress may link free fatty acids to NAFLD. Since we previously reported that hepatic stimulator substance (HSS) could protect the liver from steatosis, this study is aimed to investigate whether HSS protection could be related with its inhibit...

Hughes-Stovin syndrome (HSS) is a rare clinical disorder, which has been described as the presence of pulmonary artery aneurysm in the setting of systemic thrombosis. The term "Incomplete Behçet's Disease" has also been used to describe this syndrome due to the clinical and histopathological similarities between Behçet's disease and HSS. Indeed, pulmonary involvement can be indistinguishable be...

Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease and so far is supposed to be related with mitochondrial impairment. Hepatic stimulator substance (HSS) has been defined as a liver-protective factor promoting hepatocyte DNA synthesis and hepatic proliferation after liver intoxication. We previously reported that HSS ameliorated hepatocyte death, pro...

This paper presents an inner-outer preconditioner for symmetric positive definite matrices based on hierarchically semiseparable (HSS) matrix representation. A sequence of new HSS algorithms are developed, including some ULV-type HSS methods and triangular HSS methods. During the construction of this preconditioner, off-diagonal blocks are compressed in parallel, and an approximate HSS form is ...

Significant scale-up of donors' investments in health systems strengthening (HSS), and the increased application of harmonization mechanisms for jointly channelling donor resources in countries, necessitate the development of a common framework for tracking donors' HSS expenditures. Such a framework would make it possible to comparatively analyse donors' contributions to strengthening specific ...
