in order to study the effect of water deficit stress at different growth stages on yield and seed oil quality of rapeseed cultivars, a field experiment was conducted as split-plot in a randomized complete block design arrangement with three replications in 2009-2010 growing seasons in abarkouh in iran. four levels of irrigation were located in the main plot including, (i1) normal irrigation bas...

The transition to the New Economy accelerated in the last half of the 1990s. Using new economy index measures, one can see that rapid growth in service sector activity from 1990 to 2000, at 45 percent, overshadowed the performance of the nation’s manufacturing sector, at 22 percent (Atkinson and Court). We now live in an economy where 80 percent of all workers do not produce things. Even within...

According to the 2010 U.S. Census, close to 80 percent of the U.S. population lives in metropolitan areas, and Mississippi’s population is 49 percent urban, one of the smallest urban populations in the country. As urban populations and urban areas expand, the urban forest increases, too, and the U.S. urban area is expected to increase more than 8 percent by 2050,1 or an addition roughly the siz...

Averaged across crop, year and season , residue cover reduction was significantly less for coulter-type applicators than for disk-type applica-tors (P<0.001), disk-type applicators reduced residue cover significantly less than chisel and sweep injectors (P<0.001), and chisel and sweep injec-tors reduced residue cover similar to a tandem disk (P=0.398). Ranges of values to estimate the percentag...

INCIDENCE — Clinically significant cerebral edema occurs in approximately 1 percent of episodes of diabetic ketoacidosis in children and has a mortality rate of 20 to 90 percent; 50 to 80 percent of diabetes-related deaths are caused by cerebral edema [1-3]. Overall mortality rates for diabetic ketoacidosis (DKA) in children range from 0.15 to 0.51 percent in national population studies in Cana...

Composting experiments of fish processing wastes and wood by-products were conducted in the Andean-Patagonian Region. Fish wastes were mixed with sawdust + wood shavings (3:l ratio by weight) with two replicates. Materials were mixed and placed in 220-liter PVC reactors. After 20 days, materials were remixed and reloaded in the reactors. Samples were taken at 20, 30, 40, 60, 80 and 100 day inte...

SUMMARY Thirty-five hearts with the complete form of persistent common atrioventricular canal were classified according to the morphology of the common anterior leaflet. The ratio of specimens with a free-floating undivided common anterior leaflet (Type I) to those with a divided common anterior leaflet attached to the septum (Type II) was 1:2. Type I cases had a high incidence of other cardiac...

The share of increases in life expectancy realized after age 65 was only about 20 percent at the beginning of the 20th century for the US and 16 other countries at comparable stages of development; but that share was close to 80 percent by the dawn of the 21st century, and is almost certainly approaching 100 percent asymptotically. This new demographic transition portends a diminished survival ...

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N = 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delin...
