Determination of operation performance indicators of unit for mowing crops with the simultaneous incorporation of their stubble into the soil.

When harvesting grain crops and forage grasses using a two-phase method, trailed and/or mounted windrowers are usually used. After their passage, stubble remains on the field, which intensively loses soil moisture under sunlight and wind. To reduce these losses, the stubble, along with the soil, is crushed using disc harrows.

[Pancreatoduodenal resection with cholecystopancreatostomy. Morphofunctional substantiation and clinical results].

In the experiment on 15 mongrel dogs, the pancreatoduodenal resection (PDR) with cholecystopancreatoanastomosis (CPA) formation was modelled. The advantages of CPA over pancreatojejunostomy were confirmed by morphological and histochemical investigations. In the institute of Clinical and Experimental Surgery, from 1983 to 1987, 73 PDRs were performed with CPA creation.
