In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16  volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...

An approach to clustering is presented that adapts the basic top-down induction of decision trees method towards clustering. To this aim, it employs the principles of instance based learning. The resulting methodology is implemented in the TIC (Top down Induction of Clustering trees) system for first order clustering. The TIC system employs the first order logical decision tree representation o...

BACKGROUND Genetics plays an important role in venous thromboembolism (VTE). Factor V Leiden (FVL or rs6025) and prothrombin gene G20210A (PT or rs1799963) are the genetic variants currently tested for VTE risk assessment. We hypothesized that primary VTE risk assessment can be improved by using genetic risk scores with more genetic markers than just FVL-rs6025 and prothrombin gene PT-rs1799963...

Private George Sparr, a bugle player in the 36th regiment of foot, 23 years of age, and of a plethoric habit, was, on the 8th of May, 1817, admitted into the regimental hospital, Hilsea. He complained of violent pain in the chest, but most particularly in the right side. The pulse was full, hard, and bounding; the tongue covered with a light brown fur; the skin hot and dry ; the face deeply flu...

Comprehensive Behavioral Intervention for Tics (CBIT) has been shown to be effective for reducing tics in children with chronic tic disorder. Unfortunately, there remain significant barriers to dissemination. The aim of the current study was to examine the effectiveness of CBIT delivered over videoconference. Twenty children were randomly assigned to receive CBIT over videoconference or via tra...

OBJECTIVES The objectives of the present study are to investigate and compare the relative impact of workplace-related factors and personal characteristics on chronic psychosocial stress experience in young physicians. METHODS In a prospective study, a cohort of Swiss medical school graduates was followed up, beginning in 2001. In their fourth and eighth year after graduation, 443 physicians ...
