Magnetically driven astrophysical jets are related to accretion and involve toroidal magnetic field pressure inflating poloidal magnetic field flux surfaces. Examination of particle motion in combined gravitational and magnetic fields shows that these astrophysical jet toroidal and poloidal magnetic fields can be powered by the gravitational energy liberated by accreting dust grains that have b...

This systematic literature review examined the role of dietary macronutrient composition, food consumption and dietary patterns in predicting weight or waist circumference (WC) change, with and without prior weight reduction. The literature search covered year 2000 and onwards. Prospective cohort studies, case-control studies and interventions were included. The studies had adult (18-70 y), mos...

Cubic boron nitride (cBN) is widely applied in cutting and grinding tools. cBN grains plated by pure Ni and Ni/SiC composite were produced under the same conditions from an additive-free nickel Watts type bath. The processed electroplating products were characterized by the techniques of scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermoanalysis (TG-DTA). Due to the presence...

BACKGROUND Although increased consumption of dietary fiber and grain products is widely recommended to maintain healthy body weight, little is known about the relation of whole grains to body weight and long-term weight changes. OBJECTIVE We examined the associations between the intakes of dietary fiber and whole- or refined-grain products and weight gain over time. DESIGN In a prospective ...

One hundred twenty crossbred steers (450 lb, +/37 lb) were stratified by weight and randomly assigned to one of two feeding blocks. The cattle grazed dormant rangeland for 56 days from October 12 through December 7. Each block was supplemented three times a week with the equivalent of 7 days of dried corn distiller’s grains (DDG) at 0, 0.25, 0.50, or 0.75% body weight (BW)/d on a dry matter bas...

J. Węgrzyn Silesian University of Technology, Faculty of Materials Engineering and Metallurgy, Katowice, Poland In the process of carbothermic reaction of SiO2 + mC, key reactions appear on the surfaces of both SiO2 and C grains. However, the values of these surfaces are not known. Assuming the simplest case, quartzite and carbon grains are spheres, total surfaces of reaction were calculated fo...

background: . the aim of this study was to investigate of relationship of musculoskeletal symptoms with weight of backpack in tehran secondary school students. methods: this cross-sectional study was performed in the city of tehran in 2009. two hundred thirteen students partici­pated in study. nordic musculoskeletal questionnaire was used, asking about complaints of back, neck, and/or shoulders...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university in 2013-14. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars (ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) an...
