In domestic solar water heating evacuated tubes have been widely used. Enhancement of energy absorption is the demand time and CuO nanoparticles on account their potential uses mainly in field applications. Cost effective sol-gel method applied to synthesize glass tube. The synthesizing initiated from Cupric Acetate with colloidal solution water. A thin film has prepared at room temperature nea...

exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. measurement of the annual radiation dose hazards was performed using a halogen-quenched gm tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. the gm tube was plac...

After a dynamically active emergence phase, magnetic flux at the solar surface soon ceases to show strong signs of the subsurface dynamics of its parent magnetic structure. This indicates that some kind of disconnection of the emerged flux from its roots in the deep convection zone should take place. We propose a mechanism for the dynamical disconnection of the surface flux based upon the buoya...

This study proposed a prediction formula for the torsional strength enabling to reflect the tensile strength of ultra high performance concrete (UHPC) beams based upon the thin-walled tube theory. The remarkable ductile behavior of UHPC can also be attributed to the steel fiber reinforcement. This feature must be considered to provide rational explanation of the torsional behavior of UHPC struc...

Light-sheet fluorescence microscopy (LSFM) with single light-sheet illumination enables rapid 3Dimaging of living cells. In this paper we show the design, fabrication and characterization a diffractive optical element producing several light sheets along an inclined tube for applications in flow-driven imaging. The element, which is based on multi-focal Fresnel zone plate linear grating, genera...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

The application of X-rays to microscopic study of thin specimens was first attempted by Heycock and Neville' in 1897, two years after the discovery of X-rays. This was followed in 1913 by Goby's' demonstration of microscopic details of small biological samples by radiographing the thin specimen in close contact with a photographic plate. The negative was subsequently enlarged photographically. ...

In this series of papers the time-dependent propagation of nonlinear longitudinal-transverse waves in thin vertical magnetic flux tubes embedded in the solar atmosphere is investigated numerically using the (one-dimensional) thin tube approximation. As in the last decade the particular form of the backreaction term in the transverse equation of motion has been under considerable dispute we inve...

A thin-tube vortex method is developed to investigate the intrinsic instability within a counter-rotating vortex pair system and the e ects from the core size and the wavenumbers (or wavelengths). The numerical accuracy and the advantages of the scheme are theoretically estimated. A nearest-neighbour-image method is employed in this three-dimensional vortex simulation. Agreement with Crow’s ins...
