A positive correlation between fertility and infant mortality is generally accepted under certain conditions. The investigation of population change in two parishes in south Oxfordshire during the Stuart period was carried out as part of a Ph.D. thesis. It became apparent that there was a clear link between the death of an infant and the reduction of the subsequent intergenesic interval. It als...

In contrast to most insect guilds, gall-forming insects are thought to reach highest diversity on sclerophyllous vegetation, such as Neotropical savannas and Mediterranean vegetation types. The water and nutrient stress endured by meristems of canopy trees in tall wet tropical rainforests may cause leaf sclerophylly. Hence, the upper canopies of such ecosystems may represent a suitable habitat ...

Laser metal deposition (LMD) with a coaxial powder feeding technology has been applied to fabricate pure aluminum alloy (AlSi7Mg) and low oxidation graphene matrix (LOG-Al) composites (LOG) contents of 0.05 wt % 0.1 after the was prepared by wet ball milling. The LOG-Al showed improvements in all properties including hardness, tensile strength, ductility, modulus elasticity yield strength incre...

The HIV/AIDS-pandemic causes many problems for the most affected societies and their health care systems. One of these is the 'parent to child transmission' (PTCT) through breastmilk and its prevention (PPTCT). As economic and hygienic conditions do not always assure safe replacement feeding in developing countries, a WHO/UNAIDS/UNICEF-expert panel proposed methods to reduce the risk of PTCT bu...

BACKGROUND Butyrate, end-product of intestinal fermentation, is known to impair oxidative phosphorylation in rat liver and could disturb glycogen synthesis depending on the ATP supplied by mitochondrial oxidative phosphorylation and cytosolic glycolysis. METHODS In 48 hr-fasting rats, hepatic changes of glycogen and total ATP contents and unidirectional flux of mitochondrial ATP synthesis wer...

Three experiments were conducted to determine the effects of eating space and availability of water within feeders on the productivity and behavior of growing/finishing pigs. In Exp. 1, 12 commercial feeders were classified as being either single-space (SS) or multiple-space (MS), and either as dry (D) or wet/dry (WD), resulting in two SS-D, four MS-D, three SS-WD and three MS-WD models. Each m...

The objectives of this experiment were to determine the effects of feeding a combination of modified wet distillers grains with solubles (WDGS) and wet corn gluten feed (WCGF) on nutrient digestion, purine derivative excretion, and N utilization. Multiparous (n=20) and primiparous (n=20) cows were arranged in a replicated 5 x 5 Latin square with 21-d periods. Animals were fed one of 5 treatment...

Preconditioned steer calves weighing 690 lbs were fed diets containing on a dry basis 0, 24.9 and 47.0 percent modified wet distillers grains (DGS) for 186 days. Wet DGS replaced a portion of corn and supplement in a diet containing dry rolled corn, corn silage, tub-ground corn stalks and supplement. Steers were implanted initially with Component E-S and terminally with Component TE-S. Daily ga...
