The numerical method on a double-channel sewage pump was studied, while the corresponding experimental result was also provided.On this basis, the influence of wall roughness on the pump performance was deeply studied.The results showed that there was a critical value of wall roughness.When the wall roughness was less than the critical value, it ha
ABSTRACT: This study was conducted to explore effects of Lonicerae flos and Rhomoma curcumae longae extracts (LR) on intestinal function of broilers.Three hundred broiler chickens were randomly assigned to the following 5 groups.The control group were fed the basal diet; the antibiotic group were fed the Umbrellas basal diet supplemented with spect
BACKGROUND: Stainless steel brackets are composed of various metal that may corrode in oral cavity.Corrosion is caused by the release of metal ions such as chromium, nickel, and iron.The release of metal ions can cause adverse effects such as toxicity, allergic, and mutagenicity.To evaluate the biocompatibility of stainless steel brackets, micronuc
Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution Cover Dispensers of defensive traits in host species.Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and efficient defence used by host species.Egg-recognition experiments have advanced our
Abstract Background Two entomopathogenic fungi, Isaria fumosorosea and Metarhizium anisopliae, and one bacterium, Bacillus thuringiensis, were tested for their ability to cause mortality of Formosan subterranean termites (FST), Coptotermes formosanus (Shiraki), after liquid exposure, and for their lack of propensity to repel FST.Results The fungus
