Based on the meshing theory of ZC1 worm gear Rangehood Control PCB pair,the tooth surface contact parameters are analyzed by using MATLAB.The results show that the axial module,center distance,lead angle,radius of arc tooth profile of grinding wheel have great influence on tooth surface contact parameters.In general,the center distance is selected
An apomictic Limonium with a single pollen-stigma combination (B type), Limonium interjectum, is proposed as a new hr grip bottom species to replace the invalid name Statice dianiae Pau.The new species has a restricted distribution on the sea costs of eastern Spain (Alicante Province).It shows a striking morphological similarity to L.virgatum (Will
The purpose of the article is to disclose the migratory threats which are connected with external and mass internal inter-regional migrations, which are caused by the annexation of the Crimea and military aggression in Donbas by Russia.Methodological and practical aspects of improving the management of intensive interstate and inter-regional migrat
Despite high estimates of the heritability of aggressiveness, the genetic basis for individual differences in aggression remains unclear.Previously, we showed that the wild-derived mouse strain MSM/Ms (MSM) exhibits highly aggressive behaviors, and identified chromosome 15 (Chr 15) as the location of one of the genetic factors behind this escalated
