During operation, the electrical insulation system (EIS) of high-voltage motors is exposed to various factors that can accelerate its aging. Timely knowledge actual state EIS great help in allocating funds for service activities. The condition HV motor be assessed some extent by performing available tests. A major shortcoming lack accuracy and well-defined criteria current standards. In way, a ...

Hyperventilation (HV) and respiratory alkalosis are associated with hypophosphataemia, although the extent and duration of HV required to produce changes in serum phosphate levels are not known. We sought to characterize the effects of HV, with or without dextrose loading, on serum phosphate levels and other biochemical parameters. HV was monitored by controlling the end-tidal partial pressure ...

BACKGROUND AND PURPOSE The reliability of hematoma volume (HV) measurement using the ABC/2 method in multicenter clinical trials is unknown. We determined the accuracy of ABC/2 method as an on-site test in comparison with the gold standard central HV-assessment and semiautomatic HV-assessment. Method- We analyzed data from an acute intracerebral hemorrhage multicenter clinical trial. HV was mea...

BACKGROUND We investigated the prevalence of hallux valgus (HV) and examined its association with various factors in a cross-sectional study of Japanese female university students. METHODS A questionnaire survey of foot symptoms, lifestyle, and body mass index (BMI) was administered to 343 women who provided informed consent at a women's university. Footprints were obtained and bone density w...

Hallux valgus (HV) is a common foot deformity of multifactorial etiology, but knowledge about the relative importance of genetics and environments on HV has been limited. In order to estimate genetic influences on HV, 1,265 adults, including 175 monozygotic twin (MZ) pairs, 31 dizygotic twin (DZ) pairs, and 853 first-degree singleton family members of the twins were included from the Healthy Tw...

BACKGROUND Models assessing characteristics contributing to response to recombinant human growth hormone (rhGH) response rarely address growth extremes in both years 1 and 2 or examine how children track from year to year. Using National Cooperative Growth Study (NCGS) data, we determined characteristics contributing to responsiveness to rhGH and the pattern of change from years 1 to 2. PATIE...

BACKGROUND The aim was to describe a strategy for recruitment of healthy volunteers (HV) to a randomized trial that assessed the efficacy of different telephone techniques to assist HV in performing cardiac massage for vital emergency. Participation in the randomized trial was not financially compensated, however HV were offered emergency first-aid training. We also studied factors associated w...

Objective This study aims to assess head volume (HV) alterations at 11 to 14 weeks in fetuses with congenital heart defects (CHD). Methods A retrospective case-control study on 100 normal and 26 CHD fetuses was conducted. The fetuses had a first trimester scan with volume data sets stored from which HV was calculated. The mean HV and HV as a function of crown-rump length (CRL) in normal fetuses...

OBJECTIVE This study was aimed to evaluate relationship between hyperintense vessels (HV) on fluid-attenuated inversion recovery (FLAIR) and artery steno-occlusion related intracerebral collaterals. MATERIALS AND METHODS A total of 233 patients with 260 atherosclerotic lesions in the M1 segment of the middle cerebral artery (MCA) were examined with FLAIR and digital subtraction angiography (D...
