abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

In this research paper, the formulation of a new three-dimensional sector element based on the strain approach is presented for plate bending problems and linear static analysis of circular structures. The proposed element has the three essential external degrees of freedom (Ur, Vθ and W) at each of the eight corner nodes. The displaceme...

In this study, the vibration behavior of circular and annular graphene sheet embedded in a Visco-Pasternak foundation and coupled with temperature change and under in-plane pre-load is studied. The single-layered annular graphene sheet is coupled by an enclosing viscoelastic medium which is simulated as a Visco- Pasternak foundation. By using the nonlocal elasticity theory and classical plate t...

The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. Its effectiveness in destroying drilling foam has been test in wellbore flow simulation loop experimental stand. Experimental results showed that the operating pressure of the annular foam breaker should be larger than 0.6MPa and the stabilizers concentration of the foam drilling ...

Tissue-specific extracellular matrix plays an important role in promoting tissue regeneration and repair. We hypothesized that decellularized annular fibrosus matrix may be an appropriate scaffold for annular fibrosus tissue engineering. We aimed to determine the optimal decellularization method suitable for annular fibrosus. Annular fibrosus tissue was treated with 3 different protocols with T...

Abstract After pouring concrete precast cavity shell structure has been developing rapidly in recent years, compared with cast-in-place structure, the new fabricated low cost, high construction efficiency, and advantages of green environmental protection, shear wall is most widely used, which includes prefabricated plate shell, annular tendon layout, cast-in-situ important process. But by sever...
