Flash sintering has been investigated as a modern sintering method through examining the effect of processing parameters such as current density, temperature, and contact paste on the flash sintered 8YSZ characteristic. 95% of theoretical density was achieved at 800°С in 30sec with a field intensity of 100V.cm-1 and a current density of 160mA.mm-2. Such relative density in conventional sinterin...

Purpose: Doing plyometric training with and without the vessel occlusion is an effective practice for rapid increase of muscles strength their hypertrophy. We evaluated the effects of plyometric training with and without the vessel occlusion on electromyographic parameters. Methods: In this quasi-experimental study, 22 females were selected through convenience sampling method. They were random...

In voltage clamped photoreceptor cells of the barnacle, light-induced membrane current varied nonlinearly with membrane potential and changed sign at about + 27 millivolts (reversal potential) independently of light intensity. Instantaneous current-voltage relations were linear and intersected the voltage axis at the reversal potential. Illumination increased membrane conductance that was depen...

background black pepper (piper nigrum) is one of the well-known spices extensively used worldwide especially in india, and southeast asia. the presence of alkaloids in the pepper, namely, piperine and its three stereoisomers, isopiperine, chavicine and isochavicine are well noticed. objectives the current study evaluated the effect of lyophilization and oven drying on the stability and decompos...

This paper empirically examines the relationship between trading intensity and price in the US existing home markets. In particular, I have tested two recent theories, the search model by Wheaton (1990) and the "downpayment" model by Stein (1995). The search model predicts that trading volume should positively affect real home price, while the "downpayment" model predicts that, with liquidity c...

Transcranial direct current stimulation (tDCS) is a low-intensity, noninvasive form of brain stimulation delivered by a small battery-powered portable machine. Conventionally, 2 disposable electrodes are positioned on the head, and a small current is passed between these electrodes to stimulate the brain “transcranially.” A typical session uses a low-intensity current of 1 to 2 mA (ECT by compa...

BACKGROUND Subcutaneous adipose tissue may influence the transmission of electrical stimuli through to the skin, thus affecting both evoked torque and comfort perception associated with neuromuscular electrical stimulation (NMES). This could seriously affect the effectiveness of NMES for either rehabilitation or sports purposes. OBJECTIVE To investigate the effects of skinfold thickness (SFT)...

In addition to precise 3D coordinates, most light detection and ranging (LIDAR) systems also record "intensity", loosely defined as the strength of the backscattered echo for each measured point. To date, LIDAR intensity data have proven beneficial in a wide range of applications because they are related to surface parameters, such as reflectance. While numerous procedures have been introduced ...

It is significant to understand the effect of the light intensity and temperature on output performance of the crystalline solar modules. Therefore, it is possible to evaluate the J-V curves of solar module under various environmental conditions. This paper discuses the effect of light intensity and temperature on performance parameters of mono-crystalline and poly-crystalline silicon solar mod...

objective: to compare the efficacy of desmopressin (ddavp), tramadol and indomethacin on pain intensity of patients with acute renal colic caused by urolithiasis. m et h o d s : this prospective, randomized clinical trial was conducted between july 2005 and july 2006 including 120 patients (70 men and 50 women, mean age 38.2±5.8 years) referring to emergency room of shahid faghihi hospital with...
