Black fungus derived carbonaceous aerogel (BFA) was prepared via a convenient and energy efficient ultrasonic disposal process. The adsorption experiments of atmospheric pollutants demonstrated the superior adsorbability of black fungus aerogel on PM2.5, PM10 and formaldehyde. More importantly, black fungus aerogel (BFA) exhibited intriguing double-faced properties. We explored properties of each side of the black fungus from three aspects: water contact angle measurements, liquid selective absorption capacity and air pollutant adsorption abilities. The subsequent modification of ZnO nanosheets endowed the prepared black fungus aerogel with several valuable properties, including broad-spectrum antibacterial capability and high-efficient adsorption ability. These valuable characters implied the BFA to be a promising bacteriostat and cleaner for air and water pollution treatment.

Double - faced iso - object embroidery is carried out byusing the uneven intercalated stitch crafts of the parallel- lines stitch as a main body, being accompanied by oth-er stitch crafts and miscellaneous stitches, done on thesame textile material. This paper deals with the flower -bird double - faced embroidery fan of the Qing Dynasty,from pattern design, stitching formation and techniqueof color arrangement, describes the possible way of mak-ing double - faced embroidery with iso - object effectboth in the front and in the back.

In the present study a Genetic Programing model (GP) proposed for the prediction of relative crest settlement of concrete faced rock fill dams. To this end information of 30 large dams constructed in seven countries across the world is gathered with their reported settlements. The results showed that the GP model is able to estimate the dam settlement properly based on four properties, void ratio of dam’s body (e), height (H), vertical deformation modulus (Ev) and shape factor (Sc) of the dam. For verification of the model applicability, obtained results compared with other research methods such as Clements’s formula and the finite element model. The comparison showed that in all cases the GP model led to be more accurate than those of performed in literature. Also a proper compatibility between the GP model and the finite element model was perceived.

目的:随着高分辨计算机断层扫描(high resolution computed tomography,HRCT)普及、医疗技术和经济水平的发展,人们对支气管扩张症(bronchiectasis,BE)的关注越来越多。国内外指南对支气管扩张症病因进行广泛的研究和系统分类。然而关于病因学与疾病严重程度faced评分之间的关系研究很少。faced评分包含:FEV1%pred(第1秒用力呼气容积与预计值的百分比)(F)、年龄(A)、铜绿假单胞菌定植(C)、影像学表现(E)及英国医学研究理事会呼吸困难量表(medical research council dyspnea scal,MRC)(D)。本研究旨在探讨二者之间的相关性。方法:我们收集了2016年1月至2018年1月期间收治福建医科大学附属漳州市医院呼吸与危重症医学科的112例支气管扩张症的患者。所有患者均通过胸部HRCT扫描确定为支气管扩张,详细询问其病史及体格检查,根据英国胸科协会的《非囊性纤维化支气管扩张指南》对病因进行筛查,综合分析,从而明确病因。根据患者的年龄、肺功能、铜绿假单胞菌定植情况、胸部CT累及肺叶数、MRC对患者faced严重程度进行评定,探讨疾病的严重程度与病因之间的相关性。结果:本研究纳入112例患者,男性52例(46.4%),女性60例(53.6%),年龄183岁,平均年龄(61.0±14.8)岁,所有纳入患者的病因中包括感染后(30.4%),特发性支气管扩张(36.6%),慢性阻塞性肺疾病(Chronic obstructive pulmonary disease,COPD)(15.2%),变态反应性支气管肺曲菌病(Allergic bronchopulmonary aspergillosis,ABPA)(4.5%),结缔组织病(Connective tissue disease,CTD)(8.9%),弥漫性泛细支气管炎(Diffuse panbronchiolitis)(1.8%),支气管哮喘(1.8%),1例Kartagener综合征。而感染后支气管扩张中的病因,包括肺结核、非结核分枝杆菌、异物、误吸等,其中结核感染占47%。男女之间在病因分布上无统计学意义。支气管扩张症疾病的严重程度与年龄、铜绿假单胞菌定植、MRC及过去1年需要住院的急性加重次数呈正相关,支气管扩张症疾病的严重程度与体重指数(body mass index BMI)、FEV1%预计值呈负相关,两者均具有具有统计学意义(P值<0.05)。吸烟在重度患者中占比例较高,但不具有统计学意义。重度患者以感染后及COPD病因最多,均占总数的40.9%(P值<0.05)。肺动脉高压、肺气肿随着疾病严重程度的增高,其比例增高,提示二者与疾病严重程度密切相关,往往提示预后不佳。结论:1.在成人支气管扩张症,最常见的原因是特发性和感染后支气管扩张、慢性阻塞性肺疾病。感染后支气管扩张病因以肺结核为主。2.轻度至中度支气管扩张症多见于特发性和感染后支扩;严重病例在感染后支气管扩张和慢性阻塞性肺疾病更常见。3.支气管扩张症疾病的严重程度与年龄、铜绿假单胞菌定植、MRC、在过去1年需要住院的急性加重次数、FEV1%pred、BMI相关,肺动脉高压及肺气肿与患者的严重程度密切相关。

Based on the observationaldata at Beiluhe test site of Qinghai-Tibetan Railway, the difference ofthermal state between south faced and north faced slope was analyzed. The results indicated that the mean annualground temperature at the depth of 0.5m on south faced slopewashigher than that on north faced slope by over 3 ℃. The higher temperature on south faced slope was greatly attributed tothehigh temperature during winter time. This kind of difference in thermal state may result in asymmetric thermal regime in embankment as well as in underlying soil. As a result, theunevenly transverse deformation mayappear.
