Solar water heaters (SWHs) are one of the most effective plans for general and easy use solar energy to supply hot in domestic industrial sectors. This paper gives first-ever attempts assess optimal localization SWHs across 22 major cities Zambia, as well determine possibility generation model greenhouse gas (GHG) emission saving. The climate data used is extracted by using MeteoSyn software wh...

One of the biggest challenges for refrigeration systems is their conversion to environmentally friendly refrigerants. This attracts attention developers household equipment absorption devices (ARD), which include an unit (ARU). ARD working fluid consists natural components - ammonia water solution with addition inert gas (hydrogen). Therefore, use ARU can be considered as one options transferri...

In resource-limited settings, the lack of decentralized molecular diagnostic testing and sparse access to centralized medical facilities can present a critical barrier to timely diagnosis, treatment, and subsequent control and elimination of infectious diseases. Isothermal nucleic acid amplification methods, including reverse transcription loop-mediated isothermal amplification (RT-LAMP), are w...

Marlins, sailfish, spearfishes, and swordfish have extraocular muscles that are modified into thermogenic organs beneath the brain. The modified muscle cells, called heater cells, lack organized myofibrils and are densely packed with sarcoplasmic reticulum (SR), transverse (T) tubules, and mitochondria. Thermogenesis in the modified extraocular muscle fibers is hypothesized to be associated wit...

Defrosting is an important issue that should be considered when air source heat pump operating in a cold climate. For the transcritical CO2 (TCHP) water heater, high pressure affects application of defrosting methods. In this paper, reverse cycle (RCD) and hot gas bypass (HGBD) methods were experimentally investigated TCHP heater. The dynamic characteristics, influences on system operation over...

We investigated Legionella and Pseudomonas contamination of hot water in a cross-sectional multicentric survey in Italy. Chemical parameters (hardness, free chlorine, and trace elements) were determined. Legionella spp. were detected in 33 (22.6%) and Pseudomonas spp. in 56 (38.4%) of 146 samples. Some factors associated with Legionella contamination were heater type, tank distance and capacity...

A new open-loop heat flux control technique has been developed to conduct transient thermal testing of thick, thermallyconductive aerospace structures. This technique uses calibration of the radiant heater system power level as a function of heat flux, predicted aerodynamic heat flux, and the properties of an instrumented test article. An iterative process was used to generate open-loop heater ...

One hundred and twenty patients presenting with major peptic ulcer haemorrhage were randomised in a clinical trial comparing endoscopic injection and heater probe therapy. The two groups were well matched with regards to age, admission haemoglobin concentration, the presence of shock, non-steroidal anti-inflammatory drug usage and endoscopic findings. Permanent haemostasis was achieved in 87% o...

We demonstrate that signals at 28.5 kHz emitted from the Naval (NAU) transmitter in Puerto Rico e ectively couple into ionospheric ducts, induced/enhanced by the Arecibo HF heater, and propagate into the conjugate hemisphere as ducted whistlers. Also presented are suspected radar detections of whistler-triggered electron precipitation events. NAU-generated whistlers have intensities su cient to...

In order to generate homogeneous high temperatures at high pressures, a ring-shaped graphite heater has been developed to resistively heat diamond-anvil cell (DAC) samples up to 1300 K. By putting the heater in direct contact with the diamond anvils, this graphite heater design features the following advantages: (1) efficient heating: sample can be heated to 1300 K while the DAC body temperatur...
