Rather than landfilling, composting the organic fraction of municipal solid wastes recycles the waste as a safe and nutrient enriched soil amendment, reduces emissions of greenhouse gases and generates less leachate. The objective of this project was to investigate the composting effectiveness of three bulking agents, namely chopped wheat (Triticum) straw, chopped mature hay consisting of 80% t...

abstract     crop residues are well known for their chemical (allelopathic) effects on crops. the allelopathic potential of the aqueous extracts and chopped residual of sorghum (sorghum bicolor l.) on germination, seedling growth, relative water content, seedling dry weight, seedling length and antioxidant enzyme activity namely catalase (cat), peroxidase (pod) and superoxide dismutase (sod) of...

I . Using shccp fitted with re-entrant cannulas in the proximal duodenum, and which were given a ration containing long straw, a series of three experiments was conducted in which the flow of digcsta to the duodenum was measured and sampled continuously for 3 d. Therc appeared to be no consistent effect of this procedure on total flow of digesta to the duodenum from day to day, indicating that ...

The chromosomal spread and karyotype of Bleak (Alburnus alburnus) from Anzali lagoon were identified using tissue squashing techniques with injection of 0.5ml/100g body weight of 0.01% Colchicines solution in fish fingerlings. Kidney and gill tissues were then extracted and chopped in KCl 0.045M for 20 min and fixed in Carnoy solution in 3 stages. The chromosomal spreads were stained in 20% Gim...

The objective of this research was to evaluate the effects of residual feed intake (RFI) determined under ad libitum feeding conditions on DMI and performance of yearling ewes fed either chopped or pelleted alfalfa hay. In Exp. 1, 45 ewe-lambs had ad libitum access to a pelleted grower diet for 63 d and individual DMI was determined using an electronic feed delivery system. Residual feed intake...

Thin films are usually obtained by depositing atoms with a continuous flux. We show that using a chopped flux changes the growth and the morphology of the film. A simple scaling analysis predicts how the island densities change as a function of the frequency of the chopped flux in simple cases where aggregation is irreversible. These predictions are confirmed by computer simulations. We show th...

By-Products to Cattle W. A. HARRIS AND ROBERT H. COTTON The purposes of the present study were: 1. to compare various methods of ensiling beet tops, 2. to find how best to utilize the ensilage in cattle feeding, and 3. to compare various protein levels in a beet belt ration. The results given here are preliminary since the objectives have been only partially achieved. Ensiling was selected as a...

In general, object identification tends not to work well on ambiguous, amorphous objects such as vegetation. In this study, we developed a simple but effective approach to identify ambiguous objects and applied the method to several moss species. As a result, the model correctly classified test images with accuracy more than 90%. Using this approach will help progress in computer vision studies.

Fifteen crossbred cattle bulls of about 22-24 months age (mean body weight ranged from 291.0 to 298.1 kg) were randomly divided into 3 groups of 5 animals following randomized block design. Animals in group 1 were fed concentrate mixture containing wheat bran 97%, mineral mixture 2% and salt 1% plus ad libitum chopped green sugarcane tops (SCT) as a roughage source. Animals in group 2 were fed ...
