The process Computational Fluid Dynamic method and software used in ANSYS FLUENT. In variation 1 9 threaded blades, 2 6 threads, 3 4 threads. Based simulation results with blades highest torque at TSR 12 0....

Solar water heaters have been in use for decades many countries the world that less favorable climatic conditions solar energy as compared with Libya. However, still there is no usage of such technologies country. This could be attributed to factors including, among others, lack clear policy and/or serious plans establish technology, cheap prices conventional energy, and environmental awareness...

In the autumn of 1902 the Wright brothers spent just over eight weeks at their test site in the Kill Devil Hills near Kitty Hawk, North Carolina, testing their third Glider design. During the trial period they implemented an inter-linked roll-yaw control system. Together with the forward canard surface, this gave them control over vertical and horizontal components of the flight path. They were...

Sand and dust particle ingestion is an inevitability for aircraft operating in arid environments. For conventional takeoff landing aircraft, significant can be ingested into the gas turbine powerplant. Helicopters vertical (VTOL) are at especially high risk due to their tendency blow debris air during operations. The present study highlights development of anisokinetic sampling probe use engine...

Abstract Clostridium autoethanogenum, the bacterial model for biological conversion of waste gases into biofuels, grows under extreme carbon-monoxide (CO) concentrations. The strictly anaerobic bacterium derives its entire cellular energy and carbon from this poisonous gas, therefore requiring efficient molecular machineries CO-conversion. Here, we structurally biochemically characterized key e...

Lake Maninjau has been establihed as one of the National Priority Lakes that is used for hydroelectric powerplant, tourism, fisheries and aquaculture. The rapid increase floating net fishery (FNF) - aquaculture hassome negative impacts on pollutant loads. In order to preserve ecosystem, continuousmonitoring water quality required. This study aims determine status andtrophicclassification using ...

Next-generation sequencing has revolutionized our ability to investigate the microbiota composition of diverse and complex environments. However, a number factors can affect accuracy microbial community assessment, such as DNA extraction method, hypervariable region 16S rRNA gene targeted, or PCR primers used for amplification. The aim this study was assess influence commercially available kits...

The current electricity demand is increasing, and now the government has involved third parties in the implementation of electricity so that investors compete in building infrastructure in order to apply electricity. Thermal power is one source that has a fast break event point compared to other resources that more interested investors even with all forms of pollution caused. A form of heat pow...
