Twelve Nebraska Sandhills upland range paddocks were utilized in a two year study to determine effects of stocking rate on grazed forage nutrient composition in early summer. Stocking rates consisted of control, light, and heavy stocked at 0, 0.57, and 0.85 animal unit months per hectare respectively. Three esophageally fistulated cows per paddock collected diet samples on May 14 (d 0), May 21 ...

Four stocking densities (2, 3, 5 and 9 sheep/18 m for one hour) and two times of grazing (morning or evening) were imposed on a spaced plant nursery of nine red clover (Trifolium pratense L.) populations of varying growth habit, in order to optimize measurement of sheep grazing preference. Plant height, spread and leafiness were measured before and after each of three grazings. Sheep preference...

The forward pick area of a distribution center is a cache of conveniently located products from which order pickers can quickly draw, but which must be replenished from bulk or reserve storage. The quantities stored forward determine the amount of work required to sustain the forward pick area. Two stocking strategies that are commonly used in industry are analyzed and compared with the optimal...

Highlight: Associations among cattle stocking rate, precipitation, and eastern redcedar invasion, and possibly redcedar control measures were investigated. Redcedar numbers generally decreased as stocking rate increased. Precipitation had only a slight effect on invasion rate. Fire, cutting, and fenuron granules appear to effectively kill red cedar. Loamy upland range site consists of soils hav...

In a single-centre prospective trial 200 consecutive patients undergoing thoracic surgery were randomised to receive one of two prophylactic regimes against deep vein thrombosis (DVT). These were 5000 units of subcutaneous heparin twice a day, alone or combined with the wearing of graded compression stockings. The diagnosis of DVT was made clinically and with 131I labelled fibrinogen. Six DVTs ...

The effect on elastic stockings on ambulatory venous pressure was investigated in 22 limbs with deep venous insufficiency. The failure of some elastic stockings to reduce the ambulatory venous pressure in some limbs is due to the lack of graduated compression, which is caused by ankle-calf disproportion--narrow ankles and wide calves. This can be recognised by using the pressure-girth profile a...

In order to study the water quality in fish tanks, a 166-day (January to July 1992) experiment was realized using the indigenous species "p acu" (Piaractus mesopotamicus). Two different protein levels were tested in the diet (16% and 34% crude protein) and three stocking densities (0.25, 0.50 and 0.77 fish/m2). From the results, it was observed that the interactions between stocking density and...

This experiment evaluated forage production, sward structure, stocking rate, weight gain per area and nutritive value of forage as grazed by beef heifers on Alexandergrass (Urochloa plantaginea (Link) Hitch) pasture fertilized with nitrogen (N): 0; 100; 200 or 300 kg of N/ha. The experiment was a completely randomized design following a repeated measurement arrangement. The experimental animals...

Inventory management in markets with substituting customers is extremely challenging, not only for a downstream wholesaler, but also for upstream manufacturers. Motivated by the structures in the agrochemical market, we analyze the optimal production and stocking quantities of a manufacturer and a wholesaler, respectively, in a two-stage supply chain with upstream competition and vertical infor...
