Background & Aims of the Study: Among the environmental pollutions, noise pollution, due to the potential physiological and psychological effects on humans, is of a particular importance. Exposure to noise can result in hearing loss in citizens. Health risks from noise associated with road traffic. Noise health effects are the health consequences of elevated sound levels. This ...
Background and Objective : Noise is considered as a common occupational health hazard in a wide range of occupational settings including oil and gas industries and related companies. This research aimed to assess the environmental noise and personal exposure in a petrochemical plant. Method: First, environmental noise measurement was performed as recommended by ISO9612 (1997) and next, shor...
Neutral endopeptidase-24.11 (NEP; neprilysin; EC 3.4.24.11) and endothelin-converting enzyme (ECE) are related zinc metallopeptidases involved in the processing of biologically active peptides. Only ECE, however, exists as a disulphide-linked homodimer. The covalent linkage in rat ECE is between Cys412 in each subunit, which is equivalent to Glu403 in rabbit NEP. Here we report that directed mu...
Background and Aim: Employees in power plants are exposed to noise due to working with booster pumps, condensers, fans, boilers, steam valves, and other equipment. Noise, as a common detrimental factor, has devastating effects on human health. Today, infertility is one of the problems observed in different societies, and it is possible that noise, as a job stressor, affects fertility factors. T...
*Continuous stem radius changes (DR) include growth and water-related processes on the individual tree level. DR is assumed to provide carbon turnover information complementary to net ecosystem productivity (NEP) which integrates fluxes over the entire forest ecosystem. Here, we investigated the unexpectedly close relationship between NEP and DR and asked for causalities. *NEP (positive values ...
Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...
A bolometer thermometer with a thermal capacity C is coupled to a temperature T. 0 through a heat conductivity G and receives the power.Bolometers made with a square mesh structure can be assembled. Show a wide feature of noise not explained by the basic theory. A bolometer is a device for measuring the power of incident electromagnetic radiation via the heating of a material with a temperature...
We describe N-[(2S)-2-(mercaptomethyl)-3-methylbutanoyl]-4-(1H-pyrazol-1-yl)-L-phenylalanine (GW796406), a vasopeptidase inhibitor (VPI) that possessed approximately 3-fold selectivity for neutral endopeptidase 24.11 (NEP) versus angiotensin-converting enzyme (ACE) in in vitro assays using rat and human enzymes. In the same assays, omapatrilat, the most extensively studied VPI, displayed approx...
BACKGROUND AND PURPOSE Although myelin-associated neurite outgrowth disinhibitors have shown promise in restoring motor function after stroke, their interactive effects with motor training have rarely been investigated. The present study examined whether a combinatorial treatment (NEP 1-40+motor rehabilitation) is more effective than either treatment alone in promoting motor recovery after foca...
A high sensitivity, wideband ultrasound sensor based on a high finesse Fabry-Perot (FP) polymer film interferometer has been demonstrated with a bandwidth of 20 MHz and a 50μm diameter active area. Used in conjunction with a balanced photodetector to enable the use of a high intensity interrogating light beam of up to 36mW, the sensor system provided a noise equivalent pressure (NEP) of 0.35kPa...
