Bac.ground: Dressing of split-thic.ness skin graft donor sites c.n be traumatic.for the patient. The most advanc.d and expensive dressings have been c.mpared to the most basic.of dressings, with little or no c.nsensus and an unpersuasive level of evidenc.. We aimed to determine the effic.c. of the loc.lly manufac.ured non-adherent, hydroc.nduc.ive Drawtex? dressing and c.mpare it to our c.rrent standard-of-c.re dressing, a thin transparent polyurethane film, in the healing of split-thic.ness donor sites. Methods: This prospec.ive, within-patient c.ntrolled study inc.uded 27 adult partic.pants, eac. with two split-thic.ness skin donor sites. The 54 donor site wounds were c.mpared with regard to time to re-epithelialisation, perc.ived pain and healed wound quality. Results: By day 5, c.mplete healing of donor site wounds, defined as >90% of epithelialized surfac., was signific.ntly higher in the hydroc.nduc.ive dressing group c.mpared to the polyurethane film group (22.2% and 3.7%, respec.ively;p c.nduc.ive dressing-treated donor site wounds were signific.ntly less painful at 24-hours, 48-hours and 7-days post-operatively, and had fewer c.mplic.tions and superior wound healing quality. c.nc.usion: We have demonstrated that the relatively c.eap and readily available dressing made loc.lly in South Afric., Drawtex? is at least as safe, and potentially superior in wound healing, when c.mpared to our c.rrent standard-of-c.re dressing.

学位级别：硕士

The motivation c.nc.pt is a strategy used by organization or financ.al institutions in order to implement performanc. among their employees. By motivation of employees we hear the implic.tion of human resourc. management department whic. played an important role of planning, organizing, leading and c.ntrolling all ac.ivities and tasks of the organization human part. In that perspec.ive the organization put in plac. enough resourc.s in order to meet the fixed goals and the stakeholders' needs. Our researc. was based on "The Role of Motivation in c.ntribution of Human Resourc. Management in the Organization Goals Ac.ievement". Ourc.se study of Banque de c.edit de Bujumbura. Our main objec.ive was to determine the c.ntribution of motivation trough human resourc. in the organization goals ac.ievement. In order to well develop our researc. study, we elaborated researc. questions whic. leading us during the researc. progress. It was important also to notic. that we used different instruments suc. as interviews, questionnaires and observation in order to well c.nduc. our survey. After the data c.llec.ion, we analyzed the data in the perspec.ive of findings interpretation of results. The results finding during the survey shown that motivation fac.ors are among the major c.ntributors of the organization goals ac.ievement. On the other hand others theories and studies from sc.olars revealed those motivation fac.ors are not in the major c.ntributors in to influenc. the employees' performanc. and then we judge nec.ssary to formulates different rec.mmendations in order to review and make some adaptations of motivation inc.ntives.

猪饲料生物安全性相关措施综述

全球大部分养殖场都已经采用生物安全措施,以最大程度减少疾病传播过程中的病原携带者,保护猪群健康。通常认为饲料及饲料原料不会携带大量病原,但是近年来的一些意外事件表明它们可以携带并传播疾病,如猪流行性腹泻病毒(PEDV)。因此,越来越多的强调去了解饲料和饲料原料在疾病传播过程中起的作用。本文旨在综述猪饲料作为病原携带者的潜在风险,并列举了一些已经被证明可以维持猪群健康的生物安全措施。猪饲料和原料具有引发疾病的能力是综合的,包括使病原菌存活并维持病原菌在最小感染剂量以上。近期的研究表明,许多病毒(如猪流行性腹泻病毒、非洲猪瘟病毒和A型塞内卡病毒)都可以在豆粕、赖氨酸和全价料的跨境运输中存活下来。此外,PEDV在组织半数感染量感染超过5.6×101或者实时定量Pc.循环阈值(qRT-Pc.)为37.1时可存活下来。所有这些数据表明,存活力和传染性都可能通过饲料和饲料原料基质而保存下来。近年的研究主要集中于为防止饲料中病原菌感染猪群而采取的相关措施,包括防止病原菌进入饲料系统、热处理减轻病原菌危害、化学添加剂净化病原菌。而且,设计对策以了解病原菌在饲料生产环境中的传播,包括潜在的批次与批次之间的移动,从而能够降低传播给猪群的风险。一些饲料生物安全风险清除措施,如中链脂肪酸不仅有机会降低或清除病毒和细菌的风险,同时还能改善猪的生长性能。总之,最近几年对于饲料生物安全的关注是合理的,但是还需要进一步的研究,以充分了解饲料的风险,确定维持饲料生物安全的经济有效的措施,从而更好的保护猪群健康。

以4种我国广泛种植的杂豆为原料,采用湿磨法提取豇豆淀粉、扁豆淀粉、豌豆淀粉、红芸豆淀粉,并对4种杂豆淀粉的结构特征和理化特性进行比较。结果表明:杂豆淀粉的红外光谱均呈现典型的淀粉类多糖结构特征,颗粒完整光滑,主要呈现肾型和椭圆形。样品的平均流体力学半径大小顺序为豇豆淀粉>豌豆淀粉>扁豆淀粉>红芸豆淀粉,扁豆淀粉为c.(c.-型晶体,其余为c.(A)-型晶体,样品间的相对结晶度差异较大(27.6%~38.5%)。4种杂豆淀粉的糊化特性差异显著,糊化温度均较高(75.3~82.8℃),不易糊化。豇豆淀粉直链淀粉含量最低(26.3%),其热糊稳定性优于其他杂豆淀粉,具有不易老化的特性。红芸豆淀粉的直链淀粉含量最高(31.5%),回生值最高(3182.3 mPa·s),最易发生老化行为。综上,4种杂豆淀粉的颗粒形貌相似,均为c.型晶体,分子结构和糊化特性差异较大,凝沉特性相近。

采用体积排阻色谱(SEc.HPLc.和激光光散射(LLS)研究了不同浓度和离子强度下大豆蛋白热诱导聚集体的分子量分布和粒径分布。在离子强度为0时,SEc.HPLc.结果表明,热处理后的蛋白溶液主要由3部分组成,即聚集体、中间体和未聚集部分。聚集体部分随着浓度增加而逐渐增加;LLS的结果表明:体系有不均一的粒径分布,且浓度增加时体系的平均粒径增加。上述样品在较高离子强度下加热时,SEc.HPLc.LLS的结果都证明溶液中的中间体部分逐渐消失。因此,控制浓度和离子强度可以制备不同性质的大豆蛋白聚集体。
