The purpose of the study was to identify forage plants and specialized entomophages wheat thrips in agrocenoses winter spring grain crops cultivated Samara region. highest number adult pests noted (2365.0 ind./100 strokes), lowest barley (565.0 strokes). Egg laying by thrip females occurred on all crops. Larvae were ears wheat, triticale, barley, with exception barley. During research, two iden...

Abstract. Ironing can occur in cylindrical cup drawing whenever the thickness of drawn flange is larger than gap between punch and die. This particularly relevant for materials that present r-values lower 1.0, such as aluminium alloys, since they tend to more thickening flange. The aim this study evaluate numerically impact elastic deformation forming tools on final geometry, i.e., earing profi...

Aim. The goal of this work was to study the effect drought in critical phase ontogenesis on growth and productivity breed winter wheat plants (Triticum aestivum L.). Methods. Wheat cultivars Darunok Podillya Podolyanka were grown under optimal nutrition well-water conditions until earing-flowering phase, after that experimental transferred regime for 8 days, water supply restored end vegetation...

Abstract The Orenburg region is characterized by a sharp continental climate. It cold winters, and frequent droughts in summer. That why, the most frost-resistant winter wheat rye of crops are cultivated region, chickpea drought-resistant one grain legumes. changing climate requires constant clarification sowing dates, methods, seeding rates, emerging new liquid fertilizers require clarificatio...

Abstract. In an ongoing quest to realize lighter vehicles with improved fuel efficiency, deformation characteristics of the material AA 6016 is investigated. In the first part of this study, material behavior of Al–Mg–Si sheet alloy is investigated under different process (temperature and strain rate) and loading (uniaxial and biaxial) conditions experimentally. Later, warm cylindrical cup deep...
