Pseudo-obstruction, acquired megacolon and sigmoid volvulus constitute a group of benign lower gastrointestinal disorders that present as large bowel obstruction. In the Western society, these conditions commonly affect elderly patients with multiple comorbidities, who are often institutionalized therefore posing significant management challenges. Their clinical features, diagnosis and management will be covered in this article. [ABSTRACT FROM AUTHOR]

An innovative idea of extracting kinetic energy from man-made wind resources (chimney flue gases) with ducted horizontal axis turbine system for producing electricity is introduced in this paper. The turbine system is positioned beyond the chimney outlet, to avoid any negative impact on the chimney performance. The duct acts as a safety cover for the energy recovery system and also enhances the performance of the system. The effect of airfoils NACA4412 and NACA4416 on the power extraction by the energy recovery system using a 6-bladed ducted turbine has been studied using CFD simulation. It is observed that the average flue gas velocity in the duct section at the throat is approximately twice that of the inlet velocity, whereas maximum throat velocity achieved is 2.6 times the inlet velocity. The results from the CFD (Computational Fluid Dynamics) based simulations analysis indicate that a significant power can be harnessed from the chimney exhaust. The system may be retrofitted to existing chimneys of thermal power plants, refineries and other industries. The market potential for this energy recovery system appears to be very high due to abundant chimneys, cooling towers and other man-made air/gaseous exhaust system present globally.

There has been a big boom in the field of supply chain management. With almost all the processes related to supply chain are being carried out digitally the data has expanded to a limit where in it has to handled meticulously. Handling and extracting such an intricate widespread information big data analytics is the only rescue to resort to. Big data analysis runs on the Hadoop framework so far which allows an organization to store large quantity of data on disc and also process it. Due to increase in demand for data analytics, specifically speaking faster data analytics framework Hadoop is considered to be not fast enough. This is where Apache Spark came into picture 18 months ago. Apache Spark is termed to be 100 times faster than Hadoop and this allows an organization to process the same big data in a shorter span of time thus, addressing the increasing demand effectively. In this research paper we put forward the details about the Apache Spark framework while comparing it with the existing Hadoop framework alongside, how using Apache Spark framework in Supply chain management for data analytics would benefit the organization and businesses.

Malaria parasites adapt to the oxidative stress during their erythrocytic stages with the help of vital thioredoxin redox system and glutathione redox system. Glutathione reductase and thioredoxin reductase are important enzymes of these redox systems that help parasites to maintain an adequate intracellular redox environment. In the present study, activities of glutathione reductase and thioredoxin reductase were investigated in normal and Plasmodium berghei-infected mice red blood cells and their fractions. Activities of glutathione reductase and thioredoxin reductase in P. berghei-infected host erythrocytes were found to be higher than those in normal host cells. These enzymes were mainly confined to the cytosolic part of cell-free P. berghei. Full characterization and understanding of these enzymes may promise advances in chemotherapy of malaria.
