The mechanisms of flow-induced vascular remodeling are poorly understood, especially in the coronary microcirculation. We hypothesized that application of flow in small coronary arteries in organoid culture would cause a nitric oxide (NO)-mediated dilation and inhibit inward remodeling. We developed an organoid culture setup to drive a flow through cannulated arterioles at constant luminal pres...

In this study was examined the factors affecting the unwillingness to adopt pressurized irrigation methods among farmers' groups (with different levels of drought) in Ardabil province (Iran). Mixed method (Qualitative – Quantitative paradigm) was used for doing this research. First, by drought zoning of Ardabil province (by SPI method and GIS), three regions included the mild, moderate and seve...

Pressurized elastic shells are ubiquitous in nature and technology, from the outer walls of yeast bacterial cells to artificial pressure vessels. Indentation measurements simultaneously probe internal properties thin shells, serve as a useful tool for strength testing inferring biological functions living cells. We study effects geometry pressure-induced stress on indentation stiffness ellipsoi...

The microwave-promoted alkoxycarbonylation of aryl iodides using reaction vessels pre-pressurized with carbon monoxide is reported. Reactions are performed using 0.1 mol% palladium acetate as catalyst, DBU as base and are complete within 20-30 min. A range of aryl iodide substrates can be converted to the corresponding esters using this methodology. Primary and secondary alcohols work well wher...

In this paper, nonlinear analytical solution of pressurized thick cylindrical shells with variable thickness made of hyperelastic materials is presented. The governing equilibrium equations for the cylindrical shell with variable thickness under non-uniform internal pressure are derived based on first-order shear deformation theory (FSDT). The shell is assumed to be made of isotropic and homoge...

In this paper, the influence of internal pressure on damage resistance composite overwrapped vessels due to contact loading is studied experimentally. Pressure with different pressures are loaded quasi-statically using an indenter. The evaluated by use computed tomography scans. Subsequently, residual burst determined. shown increase for increasing during impact. order assist future experimenta...
