Ammonia emissions and odor are being used to regulate animal produc tion. The objectives of this study were to observe the effects of restricted feeding dairy heifers high concentrate (HC) and low concentrate (LC) diets with different forage quality on NH3 emissions and odor. A split plot design with diet type as the whole plot and forage quality as sub plot was administered in a 4-period (21...
it is expected that residential units may replace traditional heat and power production systems with cogeneration ones. among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. in this paper, a cogeneration system based on solid oxide fuel cells is examined. the system, including the f...
based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...
Selenium (Se) was applied to perennial ryegrass (Lolium perenne) and subterranean clover (Trifolium subterranean) pasture as a fertilizer to determine the effect of Se form and concentration on Se accumulation in subsequent forage growth. Treatments were a no Se control, 0.6 kg/ ha Se as sodium selenate, and 0.6, 1.1, and 2.2 kg/ha Se as sodium selenite, all applied to pasture plots with low so...
At signalized intersections, green times should be assigned to satisfy the traffic demand for all approaches. Stage-based signal control is the most common and basic control policy worldwide particularly at Japanese signalized intersections. It is defined as a signal control policy in which compatible traffic movements are grouped to move together in a specific time span within a signal cycle, ...
In order to maintain sustainable agriculture and prevent excessive use of chemical fertilizers, supplying part of the plant needs by organic fertilizers is necessary. In this respect, effects of nitrogen (N) source and rate on yield and yield components of forage sorghum was evaluated as a factorial experiment arranged in randomized complete blocks design with three replications at the Research...
The role of the gastrointestinal tract (GIT) in explaining the less efficient utilization of metabolizable energy (ME) in growing lambs fed forage rather than concentrate-based diets was investigated by feeding forage (legume-grass silage) and concentrate (whole shelled maize) diets, at isoenergetic intakes (ME basis), using five groups of lambs. One group of seven lambs was an initial slaughte...
. an experiment was conducted by incorporating 35 newborn balouchi lambs to study the effects of different type and levels of forage in starter diets on rumen development characteristics and performance. the 5 experimental treatments were included; starter diet without forage (control) and starter diet containing two levels (7.5 and 15%) of alfalfa hay and wheat straw. inclusion of forages incr...
