Cine films of brown pelicans flying in formation were used to measure altitudes and wing tip spacing (WTS, distance perpendicular to the flight path between wing tips of adjacent birds at maximum span) for birds flying in ground effect, and vertical displacements and WTS for birds flying out of ground effect. Views were near coplanar with the plane of flight paths, and maximum wing span was use...

this study was conducted to investigate the effect of replacing barley with different levels of ground date seeds (gds) in the diet (0, 15, 3o and 45%) on performance of local growing male goats. sixteen local male kids (average live weight 16.1±1.41 kg) were allocated randomly to four treatments (4 animal/treatment). the trial consisted of a 14 day acclimatization period followed by a 60-day m...

The present study investigated the effect of sumac (SWE) and Rosemary water extracts (RWE) on microbial growth in ground beef meat during refrigerated storage. The meat samples were explored for changes in TVC, E.coli (0157:H7) and S.aureus populations. Antimicrobial effectiveness of extracts was more pronounced against Gram-positive strain compared with Gram-negative strain. Antimicrobial impa...

the effect of barley grain processing and source of supplemental fat on performance of lactating dairy cows were studied in a replicated 4 × 4 latin square design with 21-d periods and a 2 × 2 factorial arrangement. eight holstein cows with mean body weight (bw) of 572 ± 71 kg and 45 ± 10 days in milk were allocated to 4 dietary treatments including 1) ground barley with cottonseed 2) pelleted ...

objective: in recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. methods: in this study, we tested a native planter independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). dependent var...

regarding the importance of the prevention of hazards and adverse environmental impacts in industrial and populated areas such as southern parts of tehran city, the response of impulsive period ground-supported tanks were assessed. having considered the study area's soil properties, the response of ground-supported tanks was modelled. regarding the soil properties of southern parts of tehran, t...
