Polarization for Au/Pb(Zr Ti )O /YBa Cu O ferroelectric capacitor has been studied and measured by pulse method. A sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. A value of 25?C/cm2 is measured for the satur...

A nested case-control study was designed to evaluate whether a nearly twofold excess of kidney cancer among workers at a refinery/petrochemical plant was associated with cumulative exposure to C2-C5 saturated, C2-C5 unsaturated, C6-C10 aliphatic saturated, C6-C10 aliphatic unsaturated, and C6-C10 aromatic process streams. Nonoccupational risk factors were body mass index (BMI), blood pressure (...

Barbiturates are extracted quantitatively into ethyl ether from biologic fluids buffered to pH 6. A measured portion of the ether extract is then impinged to dryness and the residue spotted on Whatman No. 2 paper that has been previously dipped in alkali and dried. The paper is developed by descending chromatography with chloroform saturated with water. The barbiturate may then be located and a...

Winter wheat (Triticum aestivum L. cv Norin No. 61) was grown at 25 degrees C until the third leaves reached about 10 cm in length and then at 15 degrees C, 25 degrees C, or 35 degrees C until full development of the third leaves (about 1 week at 25 degrees C, but 2-3 weeks at 15 degrees C or 35 degrees C). In the leaves developed at 15 degrees C, 25 degrees C, and 35 degrees C, the optimum tem...

The wild edible species Rubus ulmifolius is normally known as a source of several functional-natural compounds used in the traditional diet parts world. At present, few data are available literature about biological property its leaves, rich phenolic acids, fatty and other organic with potential antimicrobial activity. Following this hypothesis, we have investigated antibacterial activity diffe...

It is assumed that small herbivores produce negligible amounts of methane, but it is unclear whether this is a physiological peculiarity or simply a scaling effect. A respiratory chamber experiment was conducted with six rabbits (Oryctolagus cuniculus, 1.57±0.31 kg body mass) and six guinea pigs (Cavia porcellus, 0.79±0.07 kg) offered grass hay ad libitum. Daily dry matter (DM) intake and DM di...

PURPOSE To describe topographic and endoscopic anatomy of guinea pig ear for development of surgical approaches in experimental studies. METHODS Experimental study. Eight adult guinea pigs (Cavia porcellus) were used in this study. Four animals were described through endoscopic view and four animals were used to describe topographic anatomy. RESULTS The main structures of middle ear were we...

UNLABELLED To understand how the DNA answers to external agents such as cisplatin may be relevant to the diagnosis and treatment of hearing disorders caused by the administration of such drug. OBJECTIVES To investigate the cisplatin influence on the cochlea and DNA of guinea pigs. MATERIAL AND METHODS Experimental study carried out with 12 guinea pigs (Cavia porcellus). The inclusion criter...

The main goal of this work is to determine and to evaluate the saturated hydraulic conductivity for a silt loam soil in field and laboratory conditions. The experimental area was located in the Vallcebre research catchments, in headwaters of the Llobregat River (NE Spain). Hydraulic conductivity was measured in the field using the Guelph permeameter and field saturated hydraulic conductivity (K...

Abstract Due to the impacts of climate change and reduction in flow Mekong River, saline intrusion into inland has been an emergent pressing issue. The purpose this study is analyze effects various conditions (0–25‰) on changes some soil properties under laboratory conditions. Ten topsoil samples were collected from a depth 0–20 cm dry seasons rice–corn rotation fields with low salinity, Thanh ...
