ObjectiveIn order to study the active design method of normal circular arc tooth profile pure rolling cylindrical gears based on meshing line equations, to gain a deeper understanding of the meshing characteristics of this new type of gears, including contact marks and non load transmission errors, and to better grasp the effects of center distance

Crossbred Angus-by-Hereford calves (seen in photo above, and cover, at the Albaugh Ranch, Shasta County) yielded a Ibuprofen significantly higher return per head at weaning and at yearling age than straight Hereford calves out of Hereford dams of the same age, under the same environmental conditions.At weaning age, crossbred calves weighed 62 lbs m

Continuing medical education (CME) is essential for medical practitioners to update their knowledge and skills Camera Battery periodically to provide clinical care in keeping with the evidence available.Traditional methods of CME such as workshops, conferences, and seminars are helpful to bridge the gaps in practice.With advancing technologies, onl

Fine-grained visual classification (FGVC) is challenging task due to discriminative feature representations.The attention-based methods show great potential for FGVC, which neglect that the deeply digging inter-layer feature relations have an impact on refining feature learning.Similarly, the associating cross-layer features methods achieve signifi

Abstract Background The majority of parthenogenetic vertebrates derive from hybridization between sexually reproducing species, but the exact number of hybridization events ancestral to currently extant clonal lineages is difficult to determine.Usually, we do not know whether the parental species are able to contribute their genes to the parthenoge
