在一些工业中技术发展得相当迅速,以致一些受过检验的工艺和技术也常常被人们所忽视。在金属加工领域中,零部件的蒸汽处理就是一例。在生产成本不断上长的现实情况下,这种工艺值得重新提倡。蒸汽处理对于很大范围的金属零部件,在生产费用,劳动量和质量方面有明显的效益。例如,它可以提高工具寿命、防腐蚀、封闭材料中的微孔和提高外观质量。它还能增加耐磨性,减少清洗和消除或减少污水处理等。

AIM： TO evaluate the accuracy of two non-invasive tests in a population of Alaska Native persons. high rates of helicobacter pylori （h. pylon] infection, h. pyIori treatment failure, and gastric cancer in this population necessitate documentation of infection status at multiple time points over a patient＇s *** test, 13C urea breath test （UBT）, and immunoglobulin G antibodies to h. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive h. pylori test by culture or, in case of a negative culture result, by positive histology and a positive rapid urease test.RESULTS： The sensitivity and specificity of the 13C- UBT were 93% and 88%, respectively, relative to the gold standard. The antibody test had an equivalent sensitivity of 93% with a reduced specificity of 68%. The false positive results for the antibody test were associated with previous treatment for an h. pylorlinfection [relative risk （RR） = 2.8]. high levels of antibodies to h. py/or/were associated with chronic gastritis and male gender, while high scores in the 13C-UBT test were associated with older age and with theh. pylori bacteria load on histological examination （RR = 4.4）. CONCLUSION： The 13C-UBT outperformed the antibody test for h. pylori and could be used when a noninvasive test is clinically necessary to document treatment outcome or when monitoring for reinfection.

前言水禽和家禽的采精,已介绍的有用手按摩和电刺激两种不同的技术。Burrow和Quinn(1939)最初介绍了按摩采集家鸡和火鸡精液的方法。该方法稍加改进后已用于日本鹌鹑、蓝松鸡和环颈雉鸡的采精。 Watanabe(1957)报道,用手指按摩保定的公鸭大腿处采集精液。美国国际鹤基金会即用此法采集了鹤的精液。Rose(1953)和johnson(1954)采用相同的步骤也采集到家鹅的精液。

A high-order Navier-Stokes solver based on the flux reconstruction(FR)or the correction procedure via reconstruction(CPR)formulation is employed to perform a direct numerical simulation(DNS)and large eddy simulations(LES)of a well-known benchmark problem–transitional flow over the low-pressure T106C turbine ***-refinement studies are carried out to assess the resolution requirement.A 4th order(p3)simulation on the fine mesh is performed with a DNS resolution to establish a"converged"solution,including the mean pressure and skin-friction distributions,and the power spectral density in the *** LES on the coarse and fine meshes with lower order schemes are conducted to assess the mesh and order dependence of the *** particular,we study the error in the transition location,the mean skin-friction distribution,and the mean lift and drag *** h-and p-refinement studies provide a much-needed guideline in h-and p-resolutions to achieve a certain level of accuracy for industrial LES applications.

Purpose The transition into full-time training represents a key period in the development of young soccer *** we compared the weekly training loads(matches,field-,and resistance-training)of English Premier-League Academy soccer players from under-16(U16),under-18(U18)and under-23(U23)age-groups during a training *** Forty players(U16 n=13,U18 n=15 and U23 n=12)were monitored using global navigation satellite systems and differential ratings of perceived exertion(dRPE).External load metrics were total distance,high-speed running distance,[absolute:≥19.8 km/h,relative:≥87%of 30-15 final-velocity(vIFT)],sprint distance(absolute:≥25.2 km/h,relative:≥80%maximal sprint speed),and dynamic stress *** load metrics were dRPE training *** Other than relative sprint distance,overall weekly external training loads were substantially greater for U18s and U23s when compared with U16s[effect size range:1.09-1.99(moderate to large);±90%confidence limits~0.45].When compared with U16s,overall internal loads were substantially greater for U18s[0.69-0.95(moderate);±~0.40],but not *** in weekly training loads between U18s and U23s were *** Substantial differences in training loads between elite U16 players and their older counterparts,indicates the need for planned increases in training loads in anticipation of the transition into full-time training.
