A sequential extraction method for the fractionation of phosphorus （P） in lake sediments was used to analyze phos- phorus fractions of sediments taken from three large, shallow. eutrophic freshwater lakes of China-Talhu Lake. Chaohu Lake, and *** Lake. All three lakes are located in the lower reaches of the Changjiang River （Yangtze River）. In Taihu Lake and Chaohu Lake, algae blooms occurred every year, while Longgan Lake was a macrophyte-dominated lake. Results showed that exchangeable phosphorus fractions were much higher in the eutrophic lake sediments than in the macrophyte-flourishing lake sediment. Also, the ratio of Fe：P in the sediments of the algae-predomlnant lakes was generally much lower than that in the macrophyte-predominant lakes. Thus, the geochemical fractions of phosphorus in sediments had a closer relationship with the type of aquatic vegetation.

We show that the spin Hall effect of light upon reflection of one-dimensional photonic crystal with a defect layer can be enhanced significantly with a spin-dependent transverse displacement of the beam centroid of several wavelengths of light which is much larger than those reported previously,for horizontal- and vertical-polarization *** the condition of abrupt phase changes of reflection coefficients however,the spin Hall effect of light could be completely ***,we demonstrate that,by tuning the optical parameters of the defect layer,the spin Hall effect of light upon reflection can be switchable for any incident angle and polarization of incidence.

Sperm cryopreservation is an effective fertility preservation method for cancer patients before anticancer treatments. However, thereare little data on fertility preservation in large cohorts of patients with cancer in southern China. This retrospective cross-sectionalstudy aimed to assess the fertility preservation status of 1034 newly diagnosed male patients with cancer in the Human SpermBank of Guangdong Province in southern China (Guangzhou, China). Of these, 302 patients had reproductive system tumors,mostly testicular cancers (99.0%), and 732 had other tumors, including lymphoma (33.1%), gastrointestinal cancer (16.3%),nasopharyngeal carcinoma (15.7%), leukemia (7.7%), sarcoma (3.6%), and others (23.6%). Patients with reproductive systemtumors had lower sperm concentration and prefreezing and post-thawing progressive motility than those with non-reproductive systemtumors (all P luable data on the fertility preservation status in newly diagnosed cancer patients in southern China, demonstrating that patientswith reproductive system tumors had poor sperm quality for their pretreatment fertility preservation.

Based upon analysis of the seasonal fluctuation of GSI (gonado-somatic index), the spawning period of the hairtail extends from April to October. The maximum time difference between the early and the late brood individuals is about half a year. It is possible to distinguish the early brood and the late brood on the basis of the diameter of the first ring, setting 1.32 mm as a border line. Therefore, the identification of the first ring was solved in *** maturation stages can be identified on the basis of the macroscopical and microscopical characteristics of the ovary; i.e., immature (II-A, B), maturing (III-C, D, E, IV-F), mature (IV-G, V-H, VI-I) and recovering (VII-J). Maturation is completed in the course of one year from different brood seasons. The smallest size at first maturity in female was about 170-180 mm in length and 80-100 grams in *** were two discrete groups in autumn which shown the same population unit in which those individuals may separate temporarily into different

Tracking the process of fault growth in mechanical systems using a range of tests is important to avoid catastrophic failures, So, it is necessary to study the design for testability （DFT）. In this paper, to improve the testability performance of me- chanical systems for tracking fault growth, a fault evolution-test dependency model （FETDM） is proposed to implement DFT. A testability analysis method that considers fault trackability and predictability is developed to quantify the testability performance of mechanical systems. Results from experiments on a centrifugal pump show that the proposed FETDM and testability analysis method can provide guidance to engineers to improve the testability level of mechanical systems.
