Effects of magnetic fields and hydrostatic presswes on the isothermal martensitic transformation, whose nose temperature is about 140% in an Fe-25.ONi-4.OCr alloy ( mass% ) has been examined by applying magnetic fields up to 30MA/m and hydrostatic presswes up to 1.SGPa The obtained results are the following: The martensitic transformation is induced instantaneously ( less than 20psec.) under pu...

The present study was conducted to investigate current density of0.3 0.7 Al Ga N/ GaN multiple quantum well solar cell (MQWSC) under hydrostaticpressure. The effects of hydrostatic pressure were taken into account to measureparameters of 0.3 0.7 Al Ga N/ GaN MQWSC, such as interband transition energy, electronholewave functions, absorption coefficient, and dielectric con...

A root pressure probe has been used to measure the root pressure (P(r)) exerted by excised main roots of young maize plants (Zea Mays L.). Defined gradients of hydrostatic and osmotic pressure could be set up between root xylem and medium to induce radial water flows across the root cylinder in both directions. The hydraulic conductivity of the root (Lp(r)) was evaluated from root pressure rela...

The ability to measure pressure changes inside different components of a living cell is important, because it offers an alternative way to study fundamental processes that involve cell deformation. Most current techniques such as pipette aspiration, optical interferometry or external pressure probes use either indirect measurement methods or approaches that can damage the cell membrane. Here we...

In this paper, we experimentally demonstrated the fabrication and hydrostatic pressure characteristics of a twin-core photonic crystal fiber (TC-PCF). Mode couplings in the TC-PCF for x- and y-polarizations were analyzed simultaneously using group effective index of guiding modes. The output spectrum of the TC-PCF was modulated due to the combined couplings of the two polarizations. To the best...

objective: this study examines the effects of hydrostatic pressure on in vitro maturation (ivm) of oocytes derived from in vitro grown follicles. materials and methods: in this experimental study, preantral follicles were isolated from 12-day-old female nmri mice. each follicle was cultured individually in alpha minimal essential medium (α-mem) under mineral oil for 12 days. then, follicles wer...

The hydraulic conductivity of the membranes surrounding the giant axon of the squid, Dosidicus gigas, was measured. In some axons the axoplasm was partially removed by suction. Perfusion was then established by insertion of a second pipette. In other axons the axoplasm was left intact and only one pipette was inserted. In both groups hydrostatic pressure was applied by means of a water column i...
