Natural selection, through eavesdropping predators, plays a crucial role in shaping katydid behavior.Predators use the conspicuous katydid calls for prey localization.While commonly deployed defenses are known for many katydids, the possible effects of habitat and sex are not explored.We studied predator evasion among six sympatric katydid species

Due to the problem of air conditioning shortage in summer, homeless people and poor residents are threatened by high temperature, Novelty Items - Coffee Mugs - Holiday a low-energy ventilation cooling device (LEVCD) is designed to prevent heatstroke and improve the living environment.The abandoned plastic bottles, as a core ventilation cooling acce

The objective of this study was to evaluate ingredients and diets containing increasing levels of crambe cake protein replacing soybean meal protein, with in vitro ruminal fermentation parameters using a gas production technique.Diets were formulated for feedlot lambs and contained different levels of crambe cake protein (0, 250, 500, 750, and 1000

The main aim of these studies was the characterisation and identification of lactic acid (LAB) bacteria isolated from untreated silage, and the effect of selected bacteria (inoculant was called Silko for maize) on ensiling of maize high-moisture grain.Four isolates of LAB (L1, L2, L3 and L4) Skirt were characterised by the use of phenotypic assays

Backlash is a need for proper gear mesh but also a defect if not controlled closely.Few studies have focused on controlling backlash with some mechanical solutions that Exploration Sets can be applied.Few other studies have shown interest in estimation of minimum / maximum variable backlash.The operating backlash of meshing gears is affected by man
