Implication of Climate Change Induced Variation in Wind Extremes on Wind Farm in Mountainous Area of Central China—A Case Study of Hengshan

AbstractWind load is critical to the safety of wind turbines. Wind turbines are designed according to the referrence wind speed of 50-year recurrence interval. The climate change induced variation in extremes of wind could impact safety of wind turbines. Meteorological data from Hengshan weather station in central China is investigated. The wind data of 1973–1992 and 1992–2011 are utilized to estimate the extreme wind of 50-year recurrence interval using method of independent storm and generalized pareto distribution model. It is uncovered that although extreme wind of 50-year recurrence interval escalate a little during the two time spans, it will not affect the safety of wind turbines over there notably

A comparative study of the proventricular structure in twenty Chinese Tettigoniidae (Orthoptera) species

This study focuses on the proventriculus and the alimentary canal of twenty Tettigoniidae species among three subfamilies, Tettigoniinae, Phaneropterinae and Conocephalinae. Each part of the alimentary canal and the inner structure of proventriculus were examined under optic microscope and scanning electron microscopy. As a result, the length of each part of the alimentary canal and the inner structure of proventriculus were highly associated with feeding habits. Carnivorous species always had a short foregut and long cilia on the base of the sclerotized appendix in proventriculus, whereas herbivorous species always had a longer foregut and a highly sclerotized proventriculus. These results increase understanding of the alimentary canal in Tettigoniidae and will be useful in future studies of their feeding habits

Experience in nursing hydronephrosis with infection during pregnancy

目的  探讨妊娠合并肾积水伴感染患者的护理要点。方法  本组选取自2014年6月—2015年2月于徐州医学院附属医院住院的20例妊娠合并肾积水伴感染的患者，通过及早进行经尿道膀胱输尿管支架管置入术，并给予密切观察病情变化、预防感染及并发症、配合心理护理以及液体疗法。结果  20例患者全部顺利置入输尿管双J管，术中和术后无明显并发症，经抗炎治疗后所有患者48h内体温恢复正常，腰痛症状消失。胎儿出生后无畸形、智力障碍及先天性疾病报告。结论  根据妊娠期肾积水伴感染的特点进行早期护理干预、监测孕妇及胎儿情况并做好术前心理护理、完善术前准备；术中密切监测患者生命体征；术后做好并发症护理、完善出院指导对提高治愈率、促进患者早日康复有重要意义。Objective: To investigate the nursing points of hydronephrosis with infection during pregnancy. Methods: 20 cases of hydronephrosis with infection during pregnancy from June 2014 to January 2015 received bladder transurethral ureteral stent implantation. Close observation of the disease changes together with psychological care and fluid therapy was given for prevention of infection and complications. Results: Ureteral double J tubes were successfully implanted in 20 patients. No significant complications were detected during and after surgery. After anti-inflammatory treatment, body temperature and lumbago of all patients returned to normal within 48 h. No fetal malformations, mental retardation and congenital diseases were reported. Conclusion: Early nursing intervention for pregnant women and fetus should be performed according to characteristics of gestational hydronephrosis with infection during pregnancy, and monitor the situation, make the preoperative psychological nursing, and improve the preoperative preparation. Close intraoperative monitoring of vital signs of patients is essential. Postoperative nursing care of the complications and improvement of the discharge guidance are important to increase the cure rate and to promote the recovery of the patients
