A low-voltage temperature sensor designed for MEMS power harvesting systems is fabricated. The core of the sensor is a bandgap voltage reference circuit operating with a supply voltage in the range 1–1.5 V. The prototype was fabricated on a conventional 0.5 mm silicon-onsapphire (SOS) process. The sensor design consumes 15 mA of current at 1 V. The internal reference voltage is 550 mV. The temp...

Background: Attention deficit hyperactivity disorder and conduct disorder are among relatively prevalent disorders during childhood and adolescence. Considering the negative impact of the parents' drug dependency and bipolar disorder, the present study aimed to determine the prevalence of ADHD and conduct disorder in children of drug-dependent and bipolar parents. Methods: In this case-control ...

AIM The aim of this study was to determine the validity and reliability of the modified Arabic Care Dependency Scale for self-assessment of older persons in Egypt and to compare these self-assessments to proxy assessments by care givers and family members. BACKGROUND The Care Dependency Scale is an internationally used instrument to measure care dependency. The Arabic version may improve data...

in this work, the (100) surface of au and pts face centered cubic lattice, has been simulated in monte-carlo method, using a 486-dx2 computer. the potential equation that was used for the interaction among atoms in the metal surfaces is called sutton and chen potential. this potential is introduced for the interaction of floating nuclei in the electron sea, and attractive term is a many body po...

This paper studies transient thermal characteristics of ?-Ga2O3 Schottky barrier diode (SBD) packaged in TO-220. Planar and metal-oxide-semiconductor (MOS) trench anode types are evaluated. Junction temperature is estimated from dependency forward conduction measuring SBD characteristics. confirms the completeness processed junction on with extracted ideal factor height SBDs. The measured devel...

Abstract Background: Stroke is the third cause of mortality and not only leads to dependency, which is a great social, individual and cultural problem, but also can affect the physiology, immune system and coagulation system such as plasma fibrinogen, and it may potentially increase the risk of stroke. This study investigated the relationship of opium dependency and stroke. Method...

Numerical models are a means to increase the understanding of the processes occurring in the "black box" constructed wetland. Once reliable models for constructed wetlands are available they can be also used for evaluating and improving existing design criteria. The paper shows simulation results for outdoor experimental subsurface vertical flow constructed wetlands using CW2D, a multi-componen...

The changes in excess thermodynamic quantities upon the contact of two solutes immersed in a solvent are analyzed using the radial-symmetric and three-dimensional versions of the integral equation theory. A simple model mimicking a solute in water is employed. The solute-solute interaction energy is not included in the calculations. Under the isochoric condition, the solute contact always leads...

Voltage-dependent calcium channels (VDCC) in ventricular myocytes from rainbow trout (Oncorhynchus mykiss) were investigated in vitro using the perforated patch-clamp technique, which maintains the integrity of the intracellular milieu. First, we characterized the current using barium as the charge carrier and established the doses of various pharmacological agents to use these agents in additi...
