Soil parameters have significant influence on the performance of tillage machines for various kinds of tillage operations, such as soil movement by tillage tool, soil cutting, soil turning, soil pulverization, and manure injections, etc. This paper attempts to provide a clear overview of soil physical properties and soil strength, and their effects on the performance of tillage machines. Furthermore; it includes the descriptions and characteristics of these parameters, and last developed equipment and procedure for evaluating and assessing of these parameters.

Safety Critical Systems (SCS) are those systems that may cause harm to the user(s) and/or the environment if operating outside of their prescribed specifications. Such systems are used in a wide variety of domains, such as aerospace, automotive, railway transportation and healthcare. In this paper, we propose an approach to integrate safety analysis of SCSs within the Model Driven Engineering (MDE) system development process. The approach is based on model transformation and uses standard well-known techniques and open source tools for the modeling and analysis of SCSs. More specifically, the system modeled with the OMG’s standard systems modeling language, SysML, is automatically transformed in Fault Tree (FT) models, that can be analyzed with existing FT tools. The proposed model transformation takes place in two steps: a) generate FTs at the component level, in order to tackle complexity and enable reuse;and b) generate system level FTs by composing the components and their FTs. The approach is illustrated by applying it to a simplified industry-inspired case study.

＜正＞Micronemes are secretary organelles of the invasive stages of all apicomplexan parasites, and their proteins are crucial for parasite motility, adhesion and invasion to the host cell. The two twin bodies in apicomplexan sporozoites, those fuse shortly after invasion of the host cell and gradually disintegrates during the process of shizogany so as some of them to be carried by every first-stage merozoite, are known as the refractile bodies. Although the function of these bodies is not known yet, strong evidence

Randomized Integral Gain of Pi Current Controller for A Single Pv Inverter System

作者： Ahmed bashar Elhag School of Veterinary Sciences University of Nyala Sudan

＜正＞Chicken coccidiosis caused by Eimeria spp. has a major welfare and economic impact on the poultry industry. One strategy to develop a muti-antigen chicken coccidiosis vaccine was to employ live vectors to delivery putative protective Eimeria parasites antigens to immune system. The microneme-2 of E. necatrix （EnMIC2） and sporozoite surface antigen cSZ1 from E. acervulina were cloned into expression vector pYA3342 to construct recombinant attenuated S. typhimurium x4550 strains carrying EnMIC2 or cSZ1 or both EnMIC2 and cSZ1 genes, and they were expressed within attenuated S. typhimurium

This paper is concerned with the problem of network power quality when grid connected systems are used to feed the grid. These systems use power electronic components such as inverters that produce harmonics which adversely affect the power quality of the distribution network. Instead of using a conventional PI current controller with a fixed proportional and integral gain, development of new control method is considered to overcome the total harmonic emissions in PV inverters. It considers a modification to the controller where a random integral gain is used in the system. Experimental hardware is developed and result shows a reduced total harmonic distortion (THD) of the output current when tested with a resistive load.

Cirrhosis is the most important risk factor for hepatocellular carcinoma(HCC) regardless of the etiology of cirrhosis. Compared to individuals who are antihepatitis C virus(HCV) seronegative, anti-HCV seropositive individuals have a greater mortality from both hepatic as well as nonhepatic disease processes. The aim of this paper is do describe the burden of HCV infection and consider treatment strategies to reduce HCV-related morbidity and mortality. The newly developed direct acting antiviral(DAA) therapies are associated with greater rates of drug compliance, fewer adverse effects, and appear not to be limited by the presence of a variety of factors that adversely affect the outcome of interferon-based therapies. Because of the cost of the current DAA, their use has been severely rationed by insurers as well as state and federal agencies to those with advanced fibrotic liver disease(Metavir fibrosis stage F3-F4). The rationale for such rationing is that many of those recognized as having the disease progress slowly over many years and will not develop advanced liver disease manifested as chronic hepatitis C, cirrhosis, and experience any of the multiple complications of liver disease to include HCC. This mitigation has a short sided view of the cost of treatment of hepatitis C related disease processes and ignores the long-term expenses of hepatitis C treatment consisting of the cost of treatment of hepatitis C, the management of cirrhosis with or without decompensation as well as the cost of treatment of HCC and liver transplantation. We believe that treatment should include all HCV infected patients including those with stage F0-F2 fibrosis with or without evidence of coexisting liver disease. Specifically, interferon(IFN)-free regimens with the current effective DAAs without liver staging requirements and including those without evidence of hepatic diseases but having recognized extrahepatic manifestations of HCV infection is projected to be the most cost-effe

Background: Acute pancreatitis (AP) is an extensive inflammation condition that may lead to local and systemic complications, ranging from mild edematous peripancreatic fluid collection to multiorgan failure and death. Aim: To report the case of the patient with the complications that happened and the presented management. Case presentation: A 37-year-old female patient presented with acute necrotizing pancreatitis secondary to hypertriglyceridemia. During hospitalization, the patient developed severe ileus with splenic vein thrombosis. She was treated conservatively with Intravenous (IV) fluids, insulin infusion, anticoagulant, pain relief medication and antibiotics. Discussion: This case of pancreatitis induced splenic vein thrombosis (PIVST) was treated supportively with outstanding improvement of the patient’s symptoms. Conclusion: Acute pancreatitis can be complicated by splenic vein thrombosis that can be self-limited and treated with conservative measures.

This paper proposes the new cascaded series parallel design for improved dynamic performance of DC-DC buck boost converters by a new Sliding Mode Control (SMC) method. The converter is controlled using Sliding Mode Control method that utilizes the converter’s duty ratio to determine the skidding surface. System modeling and simulation results are presented. The results also showed an improved overall performance over typical PID controller, and there was no overshoot or settling time, tracking the desired output nicely. Improved converter performance and robustness were expected.
