Purpose: The oxidative stress (OS) hypothesis of overtraining syndrome argues that increased production of free radicals through exercise cause muscle fatigue and damage resulting in lower athletic performance. Several studies have investigated OS immediately before and after exercise bouts in a training macrocycle. Our study aimed to compare OS of endurance athletes between a competition macrocycle and the immediate post-season recovery macrocycle. In addition, we aimed to identify athletes who experienced an unexplainable drop in athletic performance during the competition season in order to compare their OS to those who experienced no drop in performance. Methods: Fifteen members of the University of Alaska Fairbanks cross country ski team volunteered for this study. Blood samples were taken in early February (“mid-season”) and late April (“post-season”). Participants completed questionnaires regarding physical activity and athletic performance at the time of the blood draws. Plasma was analyzed for 4-hydroxynonenal (HNE), nitrotyrosine, nitric oxide (NOX), and superoxide dismutase (SOD). Significance was determined by Wilcoxon and Mann-Whitney tests. Results: Participants displayed significantly higher (p Conclusion: Signs of oxidative stress and mitigation during the post-season recovery macrocycle were higher in athletes who reported experiencing a drop in athletic performance during the competition season macrocycle.

This paper presents and analyzes a monotone domain decomposition algorithm for solving nonlinear singularly perturbed reaction-diffusion problems of parabolic type. To solve the nonlinear weighted average finite difference scheme for the partial differential equation, we construct a monotone domain decomposition algorithm based on a Schwarz alternating method and a box-domain decomposition. This algorithm needs only to solve linear discrete systems at each iterative step and converges monotonically to the exact solution of the nonlinear discrete problem. domain decomposition algorithm is estimated The rate of convergence of the monotone Numerical experiments are presented.

针对天然气水合物藏径向井充填辅助降压开发缺乏有效模拟手段的缺陷,首先对Tough+Hydrate软件进行了二次开发,分别建立了基质和充填区中的质量和能量守恒方程,并对离散裂缝方法进行了修正,形成了径向井充填辅助降压开发数值模拟方法.然后,对比了直井降压、水平井降压、径向井降压和径向井充填辅助降压4种开发方式的产能和物理场变化规律.最后,分析了产能影响因素并提出了提高产能的措施和方向.研究结果表明,径向井充填区可有效加快自由水和分解气的产出,进而大幅提高储层降压速率.但由于充填区中的多孔介质会对流体渗流产生阻力作用,径向井充填后相比于无充填时累产气量降低了17.6%.充填区直径和渗透率越大,降压开发产能越高,但充填区分支长度存在最优值.在保证作业安全的前提下,应使用大尺寸钻头和大粒径支撑剂,进而提高降压开发产能.

Ultrasonic interferometry was utilized in conjunction with synchrotron-based X-ray diffraction and X-radiographic imaging to determine the compressional and shear wave velocities and unlt-cdl volumes of pyrite （FeS2） at room temperature and pressures up to 9.6 GPa. Fitting all of the experimental volume and velocity data to third-order finite-strain equations yielded the adiabatic zero-pressure bulk and shear moduli and their first pressure derivatives： Ks0=138.9（7） GPa, Go=U2.3（3） GPa, （δKS0/δP）T=KS0＇=6.0（1）, （δG0/δP）T=G0＇=3.0（〈1）, where the numbers in parentheses represent the 1δ uncertainty in the last significant digit. These results are in good agreement with several previous static compression studies on this material but differ quite strongly from the results obtained via first principles calculations. This study presents the first direct measurement of the bulk shear properties of this material.

大约4500年前,一群人聚集在如今英格兰西南部威尔特郡的一处墓地里。四周环绕的圆形土堆内,是再往前数400年就已经火化并安葬了的遗骨。但这群人聚在这里并不是为了举行葬礼。相反,他们准备开展一项工程,把这里改造成一个建筑奇迹。如今,他们的作品成了英国最著名且最神秘的遗迹——巨石阵。不过遗憾的是,由于这项工程开始于英国出现文字之前,他们建造巨石阵的动机无从知晓,部分建造技术也因此失传。

A parametric computational study is conducted to investigate the shear yielding, flexural yielding, and lateral torsional buckling limit states for butterfly-shaped links. After validating the accuracy of the finite element modeling approach against previous experiments, 112 computational models with different geometrical properties were constructed and analyzed including consideration of initial imperfections. The resulting yielding moment, corresponding critical shear force, the accumulation of plastic strains through the length of links as well as the amount of energy dissipated are investigated. The results indicate that as the shape of the butterfly-shaped links become too straight or conversely too narrow in the middle, peak accumulated plastic strains increase. The significant effect of plate thickness on the buckling limit state is examined in this study. Results show that overstrength for these links (peak force divided by yield force) is between 1.2 and 4.5, with straight links producing larger overstrength. Additionally, proportioning the links to delay buckling, and designing the links to yield in the flexural mode are shown to improve energy dissipation.
