We present a comprehensive study of the effects of third-order dispersion (TOD) on dispersion-managed (DM) solitons. The two main effects of TOD are creation of asymmetry of the DM soliton’s profile and generation of continuum radiation. Considering these two effects, we derive a conservative bound on the magnitude of TOD below which it will not have a significant detrimental effect on DM solit...

Methane emission factors are lacking from different livestock species in various production states fed varying diets. The objectives of the present study were to measure effects of physiological state, silage type, and supplemental NDF on DMI, DM digestibility (DMD), and methane emissions of lactating and dry dairy cows using two 4 × 4 Latin squares (5-wk periods) with four lactating (114 DIM ±...

to assess the effect of non chemical management of weed control on forage sorghum (sorghum bicolor) a field study was conducted in varamin, iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (w1= one time cultivation at 3-leaf stage using a duck foot cultivator, w2= two times cultivation at 3 and 5-...

The aim of this study was to investigate efficiency of ammonium nitrogen removal from municipal landfill leachate in activated sludge in two-stage SBR reactors. Treated leachate contains low concentrations of organic substances measured as chemical oxygen demand (COD) − 757 mg O2/dm 3 and high concentrations of ammonium − 362 mgNNH4/dm 3. Nitrification was studied in two parallel, aerated SBR r...

PURPOSE Bone remodeling has been linked to glucose metabolism in animal studies, but the results of human trials were inconclusive. Bisphosphonates may play a role in glucose metabolism through their impacts on bone remodeling enzymes. In this study, we aimed to examine the influence of alendronate usage on the incidence of type 2 diabetes mellitus (DM) among osteoporotic patients. METHODS A ...

An incomplete 8 x 8 Latin square trial (4-wk periods; 12 wk total) using 32 multiparous and 16 primiparous Holstein cows was conducted to assess the production response to crude protein (CP), digestible rumen-undegraded protein (RUP), and rumen-protected Met (RPM; fed as Mepron; Degussa Corp., Kennesaw, GA). Diets contained [dry matter (DM) basis] 21% alfalfa silage, 34% corn silage, 22 to 26% ...

Genertation of hydrogen by purple, non-sulfur bacteria of Rhodobacter sphaeroides O.U.001 was tested in photobioreactors made of different materials. Reactors made of ordinary sodium-type glass, borosilicate glass (Pyrex) or polycarbonate were applied in the present study. The applied medium containing malic acid and sodium glutamate inoculated with 0.11 or 0.31 g dry wt. of Rhodobacater sphaer...

This study was conducted to evaluate the yield, nutrient characteristics, ruminal solubility, degradability and disappearance of spent mushroom (Agaricus bisporus) substrates for ruminants. The annual yield of spent Agaricus bisporus substrates was measured to be about 210,000 tons (M/T) in South Korea. The surface soil-removed spent substrates had nutritional characteristics of high crude ash ...

milk performance (protein and fat content) and milk fatty acids (fa) profile of dairy cows under supplementation with two sources of concentrate, oilseeds (c, cottonseed) at two levels, low (5kg dm/cow/day) and high (7 kg dm/cow/day), and cereal grains (b, barley) at high rate (7 kg dm/cow/day), were studied in three herds (n=36) of spring calving holstein-friesian dairy cows (200 days in milk)...

objective There is a high burden of both diabetes (DM) and tuberculosis (TB) in China, and this study aimed to assess feasibility and results of screening patients with TB for DM within the routine healthcare setting of six health facilities. method Agreement on how to screen, monitor and record was reached in May 2011 at a stakeholders’ meeting, and training was carried out for staff in the si...
