To experimentally verify a new test stand for investigating fatigue strength of plain bearing surface layer some biand three-metallic thin-walled bearing bushes have been tested. A lining of the bearing was made of CuPb30 alloy. PbIn7 overlay was employed for tree-layer bearings. Typical views of observed bearing surface fatigue failures are presented and analysed in the paper. The MWO test rig...

This paper investigates the determination of flow resistance caused by stiff and flexible woody vegetation. A new procedure has been developed which allows the determination of friction factor f or Manning’s n using measurable characteristics of vegetation and flow. The procedure is capable of predicting flow resistance due to: (1) leafless bushes or trees and (2) leafy bushes or trees. The app...

Plum curculio, Conotrachelus nenuphar (Herbst), has become an important pest of highbush blueberries in the northeastern United States. Here, we conducted experiments in 2010-2013 to compare the efficacy of semiochemical-baited traps for C. nenuphar versus conventional (beating cloth) sampling methods in blueberries, and to understand the seasonal abundance and distribution of C. nenuphar adult...

The research on the dendroflora of Chornobyl town 30 years after accident at nuclear power plant reveal that taxonomic composition green spaces comprises 87 species and 8 decorative forms 29 families, 26 orders, 2 divisions. plantations is dominated by trees (63%), bushes (30%) vines (7%). Despite natural succession processes over past years, are introducers, which make up 57% total number taxa...

decreasing water loss and increasing the irrigation times are basic methods to develop agriculture, success in natural recourse projects, minimize the stress to planted bushes in natural fields and increase the productivity of soil and water sources. the use of super absorbent is one of these strategies to achieve these goals. the main purpose of this research was to study the effect of super a...

This article presents the results of research on study some bioecological properties honey-producing trees and shrubs. The flowering period main shrubs is March-June allows to obtain a high amount honey. During summer months, Lycium barbarum, Symphoricarpos albus, Sophora japonica species continue bloom until autumn. According data, growth rates all were at level demand. In particular, when gro...
