Corn stover has potential as a bioenergy feedstock in North America. We simulated production costs for stover harvest (three-pass and two-pass with baling or chopping, and single-pass with baling or chopping) and on-farm storage (outdoor and indoor bales, outdoor wrapped bales, and chopped stover in bags, bunks, or piles). For threeand two-pass harvest, chopping was 33e45% more expensive than b...

Two distinct strains of Schistosoma malayensis exist in Malaysia (designated the Baling and Koyan strains). Both these strains show intraspecific variations in pathology (Greer et al, 1988). To evaluate the differences in the pulmonary pathology resulting from infections of the two different strains of Malaysian schistosome, a total of 20 experimental rabbits were infected, 10 each with cercari...

Three studies were conducted to evaluate the feeding value of slice alfalfa hay in feedlot diets. In Exp. 1, 108 steer calves (183.1 +/- 1.2 kg initial BW; 6 pens/treatment) were used in a completely randomized design to evaluate the effect of baling method on performance and morbidity of newly received calves. The study lasted 28 d. Treatments consisted of a 65% concentrate receiving diet cont...

Most of the hay produced in Kentucky for feeding livestock is packaged as large round bales. Large package sizes and rapid baling rates minimize labor requirements for baling and transport around the farm (local). However, storage losses of round bales are frequently much greater than those of similar hay in smaller rectangular bales. Most of the increased storage loss for round bales appears t...

Dalam pengujian ini, fungsi dari electric ducted fan diinvestigasi dengan metode eksperimental. Sebuah diameter rotor 80 mm digunakan untuk pembelajaran. Eksperimen menggunakan alat uji gaya dorong statik. Hasil statik menunjukkan bahwa maksimum didapatkan di sekitar 30 N. Selain nilai dorong, parameter data lain yang yaitu arus, tegangan, daya, kecepatan putar baling-baling, udara, torsi, suhu...

The objective of this study was to determine the dust concentrations in selected tractor and combine operations in eastern Mediterranean region in Turkey Mean dust concentrations were 137.9 mg m(-3), 83.6 mg m(-3), 80.3 mg m(-3), and 88.8 mg m(-3) respectively for soil packing, furrowing, straw making, and baling on tractors with no cabins whereas 106.9 mg m(-3) was found in combines without ca...
