Usually, parametric synthesis of controllers for a closed control system is carried out for nominal conditions, and then the source performance for other load resistance values is estimated.As a result, the control Twin Set system may not always provide the sufficient mode stabilization with a changing load resistance value.The paper suggests an al

Pepper plants (Capsicum annuum L.cv.Zlaten Medal) were grown on nutrient solution without nitrogen, and photosynthetic response of plants was examined by determination of leaf CO2 fixation and chlorophyll and carotenoid contents.The absence of nitrogen in the medium resulted in a decrease of the leaf area and of plant biomass accumulation, and in a

An experimental study of cyclone filters of various designs is conducted.The parameters that allow increasing the degree of air Flameless Candles purification from dust are identified: air pressure at the filter inlet, working air temperature, as well as the diameter of the nozzle of the purified air consumer simulator and the diameter of the YOUTH

Flameless Candles Pavetta indica is a massive bloomer for a brief period in May.The flowers are hermaphroditic, strikingly protandrous, self and cross-compatible, nectariferous and psychophilous.They possess secondary pollen presentation mechanism as a device to avoid autonomous autogamy but it does not prevent geitonogamy.The fruit set largely occ
