Purification of nucleic acids is an essential procedure for most experiments in molecular biology. In this paper, the freeze-squeeze method with some modifications is proposed as an alternative methodology for the purification, concentration and recovery of small DNA fragments from agarose gels. The advantage of this alternative methodology is that it enables the recovery of fragments that are ...

Recently, cavitation on the surface of mechanical heart valves has been studied as a cause of fractures occurring in implanted mechanical heart valves. The cause of cavitation in mechanical heart valves was investigated using the 25 mm Medtronic Hall valve and the 23 mm Omnicarbon valve. Closing of these valves in the mitral position was simulated in an electrohydraulic totally artificial heart...

The squat exercise was usually performed with varying feet and hip angles by different populations. The objective of this study was to compare and contrast the three-dimensional knee angles, moments, and forces during dynamic squat exercises with varying feet and hip angles. Lower extremity motions and ground reaction forces for fifteen healthy subjects (9 females and 6 males) were recorded whi...

An analysis has been performed to study magneto-hydrodynamic MHD squeeze flow between two parallel infinite disks where one disk is impermeable and the other is porous with either suction or injection of the fluid. We investigate the combined effect of inertia, electromagnetic forces, and suction or injection. With the introduction of a similarity transformation, the continuity and momentum equ...

The short squeeze in GameStop attracted worldwide attention and resulted congressional hearings. increase stock from an opening price of $21 on January 26 to interday high $483 28 was not the result obvious fundamental earnings prospects. Buying pressure investors a social media site accompanied by covering, stratospheric ascent price. We use put–call parity investigate related issue no-arbitra...

Abstract Squeeze casting and powder metallurgy techniques were employed to fabricate AlSi12/Al 2 O 3 composites, which are lightweight structural materials with potential applications in the automotive industry. The impact of processing route on material properties was studied. Comparative analyses conducted for Vickers hardness, flexural strength, fracture toughness, thermal conductivity, resi...
