incidence Th e fi rst case report describing atypical fractures of the femur was published in 2005 and reported on nine adults receiving bisphosphonate treatment [1]. Since that time, the number of case reports has increased markedly, and the existence of atypical femoral fractures (AFFs) is now widely accepted. Th e incidence remains low, but substantial mortality is associated with these frac...

The knowledge compilation (KC) map [1] can be viewed as a multi-criteria evalu-ation of a number of target classes of representations for propositional KC. Usingthis map, the choice of a class for a given application can be made, consideringboth the space efficiency of it (i.e., its ability to represent information using lit-tle space), and its time efficiency, i.e., the queries...

This dosimetric study investigated the impact of multileaf collimators (MLC) leaf width in volumetric-modulated arc therapy (VMAT) for head and neck cancers (HNC), either with a "standard" simultaneously integrated boost technique (S-SIB) or with a "dose painting" SIB technique (DP-SIB). HNC patients were planned either with an S-SIB comprising three dose levels, from 56 to 70 Gy (16 patients),...

This study was carried out to determine the reproductive performance of sows in institutional swine herds which serve as model herds in Benue state, central Nigeria. Herd records on 185 sows that littered 3,995 piglets from three herds were used for the analysis of reproductive and production performance. Management practices including reproductive management, herd structure, breeds of sows, an...

In this paper, we deal to obtain some new complexity results for solving semidefinite optimization (SDO) problem by interior-point methods (IPMs). We define a new proximity function for the SDO by a new kernel function. Furthermore we formulate an algorithm for a primal dual interior-point method (IPM) for the SDO by using the proximity function and give its complexity analysis, and then we sho...

Introduction  Circumcision is the most widely practised surgical procedure in the world. One sixth of the male popuiation have a ritual circumcision. The procedure was formerly exclusively per­formed by lay practitioners, jewish rabbis and barbers with physicians playing no role in the performance and it was a purely religious rite up to the late 19th Century.  Abraham apparently first advoca...

In this report, early complications (defined as those occurring within one month post-operatively) following renal transplantation were evaluated in 373 kidney transplantations in our department. The most common complications as well as their relative frequency and method of management are discussed.

international travel has become increasingly common and accessible, hence, about two billion passengers undertake international and domestic air travel each year. venous thromboembolism (vte) is a serious public health disorder which may occur following prolonged travel, especially after air travel. a direct relation between vte development and prolonged travels has been documented, while some ...

Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...
