Recent research has found a positive relationship between functional body image and physical activity in typically developing youth; however, not been studied youth with visual impairments. Youth impairments tend to have lower engage less than their sighted peers. The purpose of this study was determine differences without the Twenty 20 disabilities completed embodied scale organized sport (OS)...

We use the new results of the HEGRA detector on the TeV γ–ray emission from MKN 501 to set upper limits on the energy density of the cosmic infrared background (CIRB). Contrary to previous interpretations of the γ–ray spectrum of MKN 421 as showing an intergalactic absorption cutoff at 5 TeV, the observed spectrum of MKN 501 extends beyond 10 TeV and appears to be unattenuated by γγ collisions ...

BACKGROUND The incidence of general anaesthesia (GA) has been used as a marker for the quality of obstetric anaesthesia care. Recent guidelines suggest the rate of GA for Caesarean section in parturients with pre-existing epidural analgesia for labour should be <3%. The primary purpose of this study is to determine whether or not this is an achievable standard in a university teaching hospital....

The effect of dopant concentration on the blue upconversion (UPC) emission of Tm(3+) -doped ZrO(2) nanocrystals under different excitation wavelengths in the red region is reported. The UPC emissions are due to the f-f electronic transitions from excited states (1)G(4) and (1)D(2) of Tm(3+). We observed a chromatic change in the UPC with tuning the excitation wavelength. The UPC emission bands ...

Objective. To analyze 25 years of mortality of extremely low-birth-weight (ELBW) neonates (≤1000 g) in a private hospital in Mexico City and to establish the current viability limit for ELBW neonates. Methods. We designed a prospective observational study of all ELBW neonates born between 1985 and 2009. Neonatal mortality, early neonatal mortality, and the 120-day mortality rate were analyzed i...

OBJECTIVE The objective of this retrospective analysis was to study the etiology, distribution, treatment modalities and complications of mandibular fractures of patients who attended the Maxillo-Facial and Oral Surgery (MFOS) unit at the School of Dentistry, University of Pretoria. METHOD The records of a representative sample of patients who presented at the MFOS unit with mandibular fractu...

The CAT (Cerenkov Array at Thémis) γ-ray detector 1 operates above 250 GeV since Autumn 1996. Its observation program has been largely devoted to the study of blazars. These objects are radio-loud active galactic nuclei (AGN’s) with a relativistic jet which is pointed directly to the observer. The jet emission dominates that of the accretion disk (and of the host galaxy) over a large energy dom...

Using the recent models of Malkan & Stecker (2001) for the infrared background radiation and extrapolating them into the optical and UV range using recent galaxy count data, we rederive the optical depth of the Universe to high energy γ-rays as a function of energy and redshift for energies betweeen 50 GeV and 100 TeV and redshifts between 0.03 and 0.3. We then use these results to derive the i...

Tax-exempt status has long been perceived as appropriate for the traditional retirement home (i.e., congregate housing and life-care facility), which serves the elderly and typically experiences low profit margins. An organization that is both organized and operated exclusively for religious, charitable, scientific, literary, or educational purposes or for testing for public safety may qualify ...
