The staged addition of feed to fertilized fish ponds was evaluated by adding fertilizers to 15 ponds stocked with Nile tilapia Oreochromis niloticus, then adding feed at half ad libitum rates once fish in the ponds reached a target weight. Each pond was stocked with 750 fish (3 fish/mz), and each treatment included three ponds with first feeding at (a) 50 g, (b) 100 g, (c) 150 g, (d) 200 g, and...

Abstract The nettle caterpillar, Setothosea asigna , is a major pest in an oil palm plantation North Sumatra, which causes severe defoliation and reduces productivity. Controlling this commonly uses Pyrethroids insecticides, but dimehypo was also used when controlling bagworms caterpillars the exact location. sublethal doses were reported to decrease mortality. study aimed determine effect of o...

The ridge furrow (RF) rainwater harvesting system is an efficient way to enhance rainwater accessibility for crops and increase winter wheat productivity in semi-arid regions. However, the RF system has not been promoted widely in the semi-arid regions, which primarily exist in remote hilly areas. To exploit its efficiency on a large-scale, the RF system needs to be tested at different amounts ...

In this paper a detailed technical analysis is presented for connecting three different sizes of wind farms (100, 200 and 500 MW) considering three different transmission solutions: 150 kV AC, 400 kV AC and ±150 kV VSC-HVDC. After a brief overview of the features of the possible connection solutions, the related operational aspects have been evaluated. A comparative economical assessment is mad...

One hundred and three outpatients with endoscopically diagnosed duodenal ulcer were randomly allocated to treatment with either cimetidine 200 mg tds and 400 mg nocte, or ranitidine 150 mg bd for four weeks.
