A 10% increase has been seen in installations in about 30 countries over the last 10 years. Places like South Algeria where four-fifths of the land is desert which has a dry desert climate, where during summer maximum temperature rises to 45 °C and during winter temperature lower below ...
When the rib height ratio rose, the augmentation became more noticeable. Due to intense turbulence induced in the main flow channel, which might have promoted mixing between the cold fluid and the heating surface, the increase in useful energy was noticeable at high Re values. Useful energy ...
However, a significant drawback of this configuration is the big size of the recuperator, which implies an increase in the investment costs of the plant [1]. The CAES plants at McIntosh and Neuenhuntorf represent the two options of operating a conventional power plant (with and without the ...
the lower water content at the irradiation area, which cannot propel the hydrogel actuator at a high speed; while for larger actuator, the increase in the weight of the hydrogel actuator will suppress the increase of the propulsion force, leading to the decrease in the movement speed as well....
a window created with "-vs osxvideosink" is initially big, but has the wrong aspect ratio (stretched image); in this case the aspect ratio changes when the window width is changed by dragging its side; the option-vs "osxvideosink force-aspect-ratio=true"can be used to make the window...

flakes using transmission electron microscopy (TEM) and atomic force microscopy (AFM). GO presented a sheet-like structure, and the SF/LiBr were adsorbed on the GO sheet (Supplementary Fig.3). The GO has a thickness of around 2 nm and the height of SF/LiBr adsorbed on the GO is ab...
Plane rides are a triple threat when it comes to spreading sickness: They force people into a closed space for a long period of time, make close contact with others unavoidable, and often bring together people from far-ranging geographic regions who may have different levels of disease vulnerabi...
These crystalline stacking relaxes upon decompression and the TBPOSS layer retains its initial monolayer state. The existence of these crystals in compressed phase is confirmed by atomic force microscopy measurements by lifting the materials on a solid substrate....
