Two interacting supersonic water jets and collisions of a jet with an aluminum target are studied experimentally by hydrodynamic simulations. Supersonic form, when shocks generated underwater electrical explosions conical wire arrays converge. The supplied ∼250 kA, ∼1 μs rise time current pulse. Underwater explosion two placed face to produces propagating in air velocities ∼2.5×103 m/s leading ...

Background: Considering nausea and vomiting are a common complaint of pregnancy. Most non-medication therapy and complementary and alternative medicine were preferred to reduce it in recent years. The aim of our study is to determine the effect of acupressure (on point KID21) on nausea and vomiting of pregnancy. Materials and Methods : This single blind clinical trial study was performed on 80 ...

superplastic materials show huge amount of deformation in low strain rates and temperature above half of melting point. in superplastic forming, estimating the pressure–time diagram and thickness distribution has significant importance. utilizing numerical methods, the involved parameters in superplastic forming can be optimized for such estimations. in the present paper, the simulation of supe...

in this paper, the boundary-based estimation of pressure distribution in the cardiovascular system is investigated using two dimensional flow images. the conventional methods of non-invasive estimation of pressure distribution in the cardiovascular flow domain use the differential form of governing equations. this study evaluates the advantages of using the integral form of the equations in the...

Freezing point depression in xylem sap of mangroves was found to range from 0.05 to 0.5 degrees , in desert plants from 0.01 to 0.16 degrees . In crush juices from leaves of Batis and Salicornia, 90% or more of the freezing point depression was made up of sodium and chlorine ions; in mangroves they constituted 50 to 70%, the rest probably being organic solutes. Plants growing in seawater have -...
