The development of conceptual geochemical models is enhanced by saturation index calculations that can identify the equilibrium state of minerals. Speciation modeling provides saturation indices that indicate reactions thermodynamically possible, minerals dissolving and precipitating in an aquifer system. In the present study, aqueous speciation modeling is carried out for the high fluoride gro...

To examine the possible relationship between systemic HT and SAS we compared 21 hypertensive (HT+) and 29 normotensive (HT-) patients for morphologic characteristics, sleep disturbances and respiratory events monitored during a full night polysomnography. There was no significant difference between HT+ and HT- patients with respect to age, weight, BMI, sleep stage distribution and disorganizati...

OBJECTIVE To test the hypothesis that comorbidity, performance of concurrent sleep apnea procedures in addition to uvulopalatopharyngoplasty, body mass index, apnea-hypopnea index, and lowest oxygen saturation are risk factors for serious perioperative complications after uvulopalatopharyngoplasty. DESIGN Prospective cohort and nested case-control studies. SETTING United States Veterans Aff...

We report our observations on day-to-day variation in serum ferritin, serum iron, total iron-binding capacity, and percent saturation of binding proteins with iron in 13 ostensibly healthy subjects during five weeks. The average intrasubject coefficients of variation were 14.5, 28.5, 4.8, and 28.0%, respectively. Precision studies on control samples showed greater within-assay and between-assay...

In this work, we propose a new statistical randomness test, the Saturation Point Test, which can be applied to integer sequences as well as binary sequences and is designed to increase the number of tests for short sequences. The subject of Saturation Point Test is the index of integer, denoted by SP , where all possible integers occur in the given sequence. We evaluate the probability Pr(SP = ...

ÐHigh-speed multiplication is frequently used in general-purpose and application-specific computer systems. These systems often support integer multiplication, where two n-bit integers are multiplied to produce a 2n-bit product. To prevent growth in word length, processors typically return the n least significant bits of the product and a flag that indicates whether or not overflow has occurred...

OBJECTIVE To determine if there is any non-linearity in the biomagnetic recordings of uterine myomas and to find any differences that may be present in the mechanisms underlying their signal dynamics. METHODS Twenty-four women were included in the study. Sixteen of them were characterised with large myomas and 8 with small ones. Uterine artery waveform measurements were evaluated by use of Pu...

BACKGROUND AND OBJECTIVES Sleep disorders, including sleep-disordered breathing and periodic limb movements during sleep, are associated with an increased risk for cardiovascular diseases, which are the leading causes of death in patients with ESRD. This study investigated the association between sleep disorders and mortality in patients with ESRD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENT...

Functional near infrared spectroscopy (fNIRS) is a non-invasive functional neuroimaging modality. Although, it is amenable to use in infants and young children, there is a lack of fNIRS research within the toddler age range. In this study, we used fNIRS to measure cerebral hemodynamics in the prefrontal cortex (PFC) in 18-36 months old toddlers (n = 29) as part of a longitudinal study that enro...

Abstract The main aim of this experimental study is to test the novel type coupon installation. This set-up was used carry out corrosion process under aggressive conditions. Moreover, effect inhibitors on scale-forming tendency evaluated. corrosive conditions were defined by using Langelier Saturation Index (this index an approximate indicator degree saturation CaCO 3 in water) and Ryznar stabi...
