Urban living is associated with an increase in cardiometabolic risks, but the speed at which these risks are accrued over time is unknown. Using a cross-sectional sibling-pair design, the authors surveyed migrant factory workers and their spouses from 4 cities in India together with their rural-dwelling siblings and examined the associations between urban life-years and cardiometabolic risk fac...
We challenge the hypothesis that fin whales use a magnetic sense to guide migration by testing for associations between geophysical parameters and the positions where fin whales were observed over the continental shelf off the northeastern United States. Monte Carlo simulations estimated the probability that the distribution of fin whale sighting was random with respect to bottom depth, bottom ...
Objective: there are still disputes over the effect of using slope strategy on the reduction of peak pressure and time of pressure on the foot. Therefore, the objective of this study was to evaluate the effect of internal and external wedge slope changes on the mechanical parameters of foot ulcers. Methods: In this quasi-experimental study 15 diabetic patients with an average age of 63.3&plusm...
Leaf appearance rate and phyllochron are related variables which play a central role in forage production. Phyllochron is the time interval between the appearance of successive leaves and varies according to a number of environmental factors, among which temperature is the most important. The experiment was conducted in natural pasture with the aim of testing phyllochron variation under differe...
Soil movement by tillage redistributes soil within the profile and throughout the landscape, resulting in soil removal from convex slope positions and soil accumulation in concave slope positions. Previous investigations of the spatial variability in surface soil properties and crop yield in a glacial till landscape in west central Minnesota indicated that wheat (Triticum aestivum) yields were ...
The issues of filling the information model with data on state wheel-rail tribosystem are considered. “Program for modeling transverse position a wheelset in track” is used, and main modules program described. geometrical parameters contact wheel profile rail obtained. values nominal extreme intermediate positions pair track calculated. displacement track, its slope, width rail, gap between cre...
[1] We measured characteristics of soil organic carbon (SOC) and black carbon (BC) along opposed northand south-facing toposequences in recent (2004) and old ( 1860–1950) burn sites throughout interior Alaska. Surface fuel consumption did not vary between different topographic positions, with 3.3 (±0.5) kg C m 2 being consumed on toe slope sites, 4.0 (±0.2) kg C m 2 on north-slope sites, and 3....
