The defect energy levels for muonium, a light pseudo-isotope of hydrogen, are investigated to define the equivalent of the H1⁄2þ= level which is predicted to be fixed at a universal energy. Existing results for Mu at donor and acceptor sites in silicon tentatively place Mu1⁄2þ= approximately 0.5 eV above the predicted hydrogen level. Measured donor ionization energies in other materials in whic...

Maximal exercise performance is decreased when breathing from a self-contained breathing apparatus (SCBA), owing to a ventilatory limitation imposed by the increased expiratory resistance. To test the hypothesis that decreasing the density of the breathing gas would improve maximal exercise performance, we studied 15 men during four graded exercise tests with the SCBA. Participants breathed a d...

The paper incorporates liquid reserves, interest and dividends in the compound Poisson surplus model. When an insurer’s surplus is below a certain level, it is kept as liquid reserves. As the surplus attains the level, the excess of the surplus above the level will earn interest at a constant interest rate. If the surplus continues to surpass a higher level, the excess of the surplus above this...

Objective: Diabetic patients suffer from different types of complications associated with peripheral nerves. A clear manifestation of these complications is found in the mouth where neuropathies commonly occur. The measurement of electrical stimulation threshold of teeth signifies premature involvement of peripheral nerves in the teeth. The aim of present study is to compare pulp tester respons...

In this paper, we analyse information leakage in Ryan’s Prêt à Voter with Paillier encryption scheme (PAVPaillier). Our analysis shows that although PAV-Paillier seems to achieve a high level of voter privacy at first glance, it might still leak voter’s choice information in some circumstances. Some threats are trivial and have appeared in the literature, but others are more complicated because...

exposing the ear to an intense noise will probably cause to hearing loss. this loss may be temporary threshold shift (tts), permanent threshold shift (pts), or a combination of the two. the average audiograms for the 157 textile workers, exposed to an average 100 db (a) overall noise level, in 5 age groups indicated that the losses were most prominent for frequencies of 3 to 6 kc/s showing a pe...

in this research, air sampling of workplaces was carried out by two methods (long - time and short - time). the mean formaldehyde concentration with long - time method in pathology labs, surgery and endoscopy sections were 0.96 0.25 and 0.13 ppm and with short - time method, 8 hours, was 3, 0.3 and 0.2 ppm. the mean formaldehyde concentration in pathology labs was above the standard values (tlv...

BACKGROUND This study examined the relative contribution of genetic and environmental effects on the air-conducted hearing threshold level (0.5-4 kHz) and speech recognition threshold level of the better ear as well as self-reported hearing in older women. METHODS Hearing was measured as a part of the Finnish Twin Study on Aging in 103 monozygotic (MZ) and 114 dizygotic (DZ) female twin pairs...

a b s t r a c t there are three types of nerve fibers that are involved in the transmission of pain stimuli: c fibers (slower fibers) for thermal, mechanical and chemical stimuli, a-delta fibers for thermal or mechanical stimuli and a-beta fibers for touch stimuli. clinically, this is crucial in making an accurate assessment of the pain level experienced by a suffering patient, in indicating th...

Level shifters play critical roles in ultra low-voltage circuits and systems. a new low power level shifter (LS) is presented for robust logic voltage shifting from near/sub threshold to above threshold domain. The new circuit combines the multi threshold CMOS technique along with novel topological modifications to guarantee a wide voltage conversion range with limited static power and total en...
