GENETIC STRUCTURE AMONG FOUR POPULATIONS OF PADDLEFISH, POLYODON SPATHULA (ACTINOPTERYGII: ACIPENSERIFORMES: POLYODONTIDAE), BASED ON DISOMIC MICROSATELLITE MARKERS

Background.The paddlefish, Polyodon spathula (Walbaum, 1792), is an important species for commercial and recreational fisheries throughout the central United States.Populations have declined in many areas due Extractor Fan to river modification, loss of spawning habitat, pollution, and over-exploitation.Assessing genetic diversity of a species is a

Utilizing supervised machine learning algorithms to develop a surveillance and response system based on symptoms of diarrhoea, contingent on the Support Vector Machine (SVM) to predict the probable disease using labelled data.Diarrhoea is amongst the top ten diseases which kill.A prototype system is developed based on the SVM algorithm.The prototyp

A total of 59 yeast isolates from Xiaoqu from five different regions of Guizhou were identified to belong to six species by sequencing of the D1/D2 domain of the 26S rRNA gene, including Trichosporon asahii (one strain), Saccharomycopsis fibuligera (32 strains), Saccharomycopsis malanga (8 strains), Hyphopichia burtonii (4 strains), Wickerhamomyces

In order to analyze the dynamic fracture responses of surrounding rocks in underground space to cyclic impact loads, a series of dynamic compressive tests were conducted using hollow cylindrical and intact sandstone specimens under Compression Stockings confining pressures corresponding to 5, 10, and 12 MPa, and the hollow cylindrical sandstone wer
