This research deals with the processing of wood using a circular saw, which is associated several risks and factors that affect wood-splitting process. One them wear teeth saw blade change magnitude cutting forces. The aim this study to compare real measured values theoretical when Norway spruce two types blades, i.e., sintered carbide (SC) high-speed steel (HSS), diameter 600 mm 54 56 teeth, r...

UNLABELLED We report on a 5-year-old girl who presented with the full clinical criteria of Hallermann-Streiff syndrome (HSS). Classically, overtubulation (thin and gracile) bones are the characteristic and constant features in HSS. Interestingly, our present patient manifested unusual mid-diaphyseal endosteal thickening with subsequent medullary narrowing (defective endosteal resorption). To th...

This study describes the influence of the steel characteristics of Ca-treated carburising steel grades during hard part turning of synchronising rings in gearbox production. The main focus was on the chemical composition of the non-metallic inclusions in the evaluated workpieces and their effect on the PCBN tool wear. In addition, a Ca-treated carburising steel grade was compared to a standard ...

The wear mechanisms of cutting tools made of tungsten-carbide (WC), PCBN and PCD were investigated using the tool life and temperature results available in the literature. For tool/work combinations WC/steel and PCBN/hardened-steel, under practical conditions, tool wear was found to be greatly influenced by the temperature. It was concluded that the most likely dominant tool wear mechanism for ...

Wire electric discharge machining (WEDM) is one of the advanced machining processes. Response surface methodology coupled with Grey relation analysis method has been proposed and used to optimise the machining parameters of WEDM. A face centred cubic design is used for conducting experiments on high speed steel (HSS) M2 grade workpiece material. The regression model of significant factors such ...

‘Hierarchical Semi-separable’ matrices (HSS matrices) form an important class of structured matrices for which matrix transformation algorithms that are linear in the number of equations (and a function of other structural parameters) can be given. In particular, a system of linear equations Ax = b can be solved with linear complexity in the size of the matrix, the overall complexity being line...

BACKGROUND The self-rating score (SRS) versus examiner rating score (ERS) in measuring helplessness in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been yet compared in a prospective study. We, therefore, investigated SRS versus ERS in 115 patients. PATIENTS AND METHODS In an extension of the Kuopio Breast Cancer Study 115 women ...

PROBLEM Although efforts to integrate health systems science (HSS) topics, such as patient safety, quality improvement (QI), interprofessionalism, and population health, into health professions curricula are increasing, the rate of change has been slow. APPROACH The Teachers of Quality Academy (TQA), Brody School of Medicine at East Carolina University, was established in January 2014 with th...

The relationship between DNase I-hypersensitive sites (HSs) and transcriptional enhancers of the rat tyrosine aminotransferase (TAT) gene was examined by comparing HSs in and around the TAT gene with the activity of the corresponding DNA sequences in transient transfection assays. In this manner, we identified two HSs as liver-specific enhancers. Of three hepatoma cell lines examined, only one ...

This paper presents a residential hybrid thermal/electrical grid-connected home energy system (HES), including a fuel-cell with combined heat and power and a battery-based energy storage system. The minimum operation cost of this integrated energy system is achieved by proper scheduling of different energy resources, found by applying a new powerful optimization algorithm, the Hyper-Spherical S...
