The relevance of the study is due to problem that characteristic various types screw press structures, which leave up 16% oil in cake when pressing sunflower oil. In this regard, purpose find rational methods improve design twin-screw extrusion presses increase yield. leading for solving are empirical research allow comprehensively considering stages improving geometric configuration shaft base...

Introduction. The presses are powered machines having stationary beds and slides (rams) which have controlled sliding motion towards away from the beds, guided by frames. Metal can be worked in power press a wide verity of ways like punching, shearing, forming, etc. Crankshaft is one basic components for transmission, transmits rotary to mechanical press. It around this element that all stresse...

Anthropogenic nutrient inputs into native ecosystems cause fluctuations in resources that normally limit plant growth, which has important consequences for associated food webs. Such inputs from agricultural and urban habitats into nearby natural systems are increasing globally and can be highly variable, spanning the range from sporadic to continuous. Despite the global increase in anthropogen...

In this protocol, social motivation is measured in mice through a pair of operant conditioning paradigms. To conduct the experiments, two-chambered shuttle boxes were equipped with two operant levers (left and right) and a food receptacle in one chamber, which was then divided from the second chamber by an automated guillotine door covered by a wire grid. Different stimulus mice, rotated across...

The paper analyses the compaction of cardboard waste in vertically stationary presses, stages making bale material and forces resistant to displacement pressing plate at each stage compaction, relationship between piston stroke forces, as well partial total energy consumption compaction. Some clarifications are made regarding correlation time, respectively A link shall also be established volum...

the replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of holstein heifers have been evaluated. fifteen holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% ...
