Pulmonary hypertension (PH) is characterized by elevated pulmonary arterial pressure leading to right-sided heart failure and can arise from a wide range of etiologies. The most common cause of PH, termed Group 2 PH, is left-sided heart failure and is commonly known as pulmonary hypertension with left heart disease (PH-LHD). Importantly, while sharing many clinical features with pulmonary arter...

Left heart disease (LHD) is probably the most frequent cause of pulmonary hypertension (PH). Although rheumatic mitral valve stenosis has been in the past the most common cause of this condition, PH-LHD mainly results from heart failure related to systolic and/or diastolic dysfunction of the left ventricle and is associated with elevated left-sided cardiac filling pressures. Most patients have ...

Due to the increasing number of mobile users, there is a huge demand of Base Transceiver Station (BTS) particularly in rural and semi urban areas. These BTS are operated on diesel generator (DG) and also connected with the existing grid supply. However, the grid supply is rarely available in most of the remote locations. Therefore, diesel generators are mainly used for providing the continuous ...

The prevailing massive exploitation of conventional fuels has staked the energy accessibility to future generations. gloomy peril inflated demand and depleting fuel reservoirs in sector supposedly instigated urgent need for reliable alternative fuels. These very issues have been addressed by introducing oxyhydrogen gas (HHO) compression ignition (CI) engines various flow rates with diesel asses...

Biofuel is a prominent alternative fuel because of its environmental benefits and similar physiochemical properties to diesel fuel. This study investigated the impact of high quality refined, bleached and deodorized (RBD) coconut oil blends and fuel throttle setting on performance and exhaust emissions of diesel engine. The criteria regulated emissions and particulate-phase polycyclic aromatic ...

Desulfurization of a commercial diesel fuel by different adsorbents was studied in a fixed-bed adsorber operated at ambient temperature and pressure. In general, the adsorbents tested for total sulfur adsorption capacity at breakthrough followed the order: AC/Cu(I)-Y Cu(I)-Y Selexsorb CDX (alumina) CuCl/ -Al2O3 activated carbon Cu(I)-ZSM-5. The best adsorbent, AC/Cu(I)-Y (layered bed of 15 wt %...

This study deals with artificial neural network (ANN) modeling a diesel engine using waste cooking biodiesel fuel to predict the brake power, torque, specific fuel consumption and exhaust emissions of engine. To acquire data for training and testing the proposed ANN, two cylinders, four-stroke diesel engine was fuelled with waste vegetable cooking biodiesel and diesel fuel blends and operated a...

BACKGROUND Hepatectomy and additional common bile duct exploration are required for the treatment of left-sided hepatolithiasis (LSH). METHODS Eligible LSH patients (n = 62) scheduled for open left lateral segmentectomy or left hemihepatectomy with intraoperative biliary exploration via the left hepatic duct orifice (LHD group, n = 35) or the common bile duct (CBD group, n = 27) were retrospe...

OBJECTIVE To describe the anatomical variation occurring in intrahepatic bile ducts (IHDs) in terms of their branching patterns, and to determine the frequency of each variation. MATERIALS AND METHODS The study group consisted of 300 consecutive donors for liver transplantation who underwent intraoperative cholangiography. Anatomical variation in IHDs was classified according to the branching...

Local health department (LHD) vector control programs have experienced reductions in funding and capacity. Acknowledging this situation and its potential effect on the ability to respond to vector-borne diseases, the U.S. Centers for Disease Control and Prevention and the Public Health Foundation partnered on a performance management initiative for LHD vector control programs. The initiative in...
