Evaluation of rate trend patterns via segmented regression: Case study of crime rates of Pakistan

  In many practical regression-type problems, one uniform regression function to the data was found inappropriate, since the functional relationship between the response and the regressor(s) changes at certain points of regressors. These points are usually called break points or change points. In such situations, regression models are applied that are obtained by a piecewise definition of the regression...

Grape seed proanthocyanidin extract ameliorates diabetic nephropathy in rats

  This study examined the effects of grape seed proanthocyanidin extract (GSPE) on kidney of diabetic nephropathy rats. Male Sprague-Dawley rats were divided into three Groups: control, diabetic nephropathy, diabetic nephropathy and received GSPE 500 mg/kg for 6 weeks. At first, 24-h urinary albumin excretion (UAE) was studied two weeks after induction of diabetes then each week until the end of the...

Generic computing of enhanced speckle reduction on low end ultrasound machine images

  Due to the emergence of microelectronics, ultrasound diagnostic machine can now be manufactured at low cost. The affordability of low cost ultrasound diagnostic machine is of utter importance in allowing wider exposure of ultrasound technology to the general public. Nonetheless, in comparison with international standard requirements, the quality of images from low cost ultrasound machine is still lacking....

Effects of four depths of spodic horizon on root morphology and nutrient partitioning of kenaf grown on sandy beach ridge soil

  Kenaf has a potential to be an industrial crop in Malaysia. Hence, this study was conducted to investigate the root morphology, nutrient partitioning and yield of kenaf at various depths of spodic horizons in beach ridges interspersed with swales (BRIS) soil. Study was conducted at RhuTapai Research Station, Terengganu, Peninsular Malaysia. Kenaf was grown at L1 20 cm, L2 48 cm, L3 77 cm and L4 118 cm...

An unusual case of Henoch-Schönlein purpura associated with varicella zoster infection

  Henoch-Schönlein purpura (HSP) is one of the most common vasculitis of childhood which is characterized by nonthrombocytopenic palpable purpura, arthritis, renal and gastrointestinal system (GIS) involvement. The etiology of HSP is mainly unknown and antecedent upper respiratory tract infection, usually viral and Streptococcal origin, drugs, cold, insect bite or some foods are the known triggering...

Development of humanized monoclonal antibody by logical approach: Characterization, functional studies in vitro and immunogenicity studies in vivo in non-human primates

  Monoclonal antibodies (mAbs) are widely used due to their exquisite specificity and once were hailed as the solution to cancer. However, when mouse mAbs are administered in humans, anti-antibody response (AAR) is frequently observed. Using humanized mAbs which are commonly developed by CDR-grafting method, the AAR is negligible, but loss of binding has also been consistently reported. Therefore, in an effort...

Multi-machine power system stabilizer design using improved particle swarm optimization (PSO) with time-varying acceleration coefficients

  An efficient and most famous tool to enhance damping of the power system low frequency oscillations is the conventional widely used lead-lag Power System Stabilizer (PSS). To achieve the desired level of robust performance under transient situation, selecting a suitable design method for optimal tuning of PSS parameters is very important in multi-machine power system. Because, it is a multimodal and difficult...

Use of neuro fuzzy network with hybrid intelligent optimization techniques for weight determination in parallel Job scheduling

  This paper is concerned with the performance tuning of the fuzzy logic controller (FLC) used for the process grain sized scheduling of parallel jobs. First, we have proposed a scheduling algorithm called agile algorithm. The performance of the agile algorithm depends on how the processes of the applications are coscheduled. The performance of the scheduling algorithm is evaluated using the features of the...

Sexual induction to male on Tilapia (Oreochromis niloticus L.) using 17α-methyltestosterone

  Tilapia (Oreochromis sp.) is one of the main species in aquaculture today due to its nutritional characteristics and high tolerance to different culture media. However, commercial tilapia production generally requires the use of monosex populations with male individuals. One way to obtain this kind of fish stock is through the use of hormones, after which during the production cycle, the reproductive...
