建筑业是埃塞俄比亚经济的支柱,据粗略估计,建筑业对工业领域的贡献率超过一半以上,大约为70.9%,这表明建筑活动如公路、铁路、水坝和住宅扩建等在经济建设方面发挥着主导作用。多年来,埃塞俄比亚的建筑成本增长速度快于通货膨胀,使得建筑成本越来越高。在材料废弃物减量化中,一些工具和方法已经被概念化,缺乏基于定量数据的研究。因此,本硕士论文旨在开发一种用于识别和测量材料浪费的原因工具,并据此指导如何优先进行重大的浪费减少活动,并评估其对建筑施工项目的影响。此外,本研究试图评估亚的斯亚贝巴在一些高层建筑建设项目中对建筑材料的管理和尽量减少浪费的现状,并就如何尽量减少建筑材料浪费提出建议。研究结果显示,受访者(承包商、顾问和客人)就废物来源对废物产生的贡献程度的见解上有差异。分析结果从承包商、顾问和业主的第一位到第五位不等,认为造成建筑施工项目建筑垃圾的最重要因素是:现场管理和实践因素、材料搬运和储存因、操作因素、设计和文件因素、和现场监督因素。这些因素是建筑材料浪费的原因,并将对项目的生产率、环境、成本和工期产生影响。

In past decades, alginate-based multilayer microcapsules have been given important attention in various pharmaceutical investigations. Alginate-poly l lysine-alginate(APA) is studied the most. Due to the similarity between the structure of polyethyleneimine(PEI) and poly-L-lysine(PLL) and also lower price of PEI than PLL, this study was conducted to compare the efficacy of linear(LPEI) and branch(BPEI) forms of PEI with PLL as covering layers in fabrication of microcapsules. The microcapsules were fabricated using electrostatic bead generator and their shape/size, surface roughness, mechanical strength, and interlayer interactions were also investigated using optical microscopy, AFM, explosion test and FTIR, respectively. Furthermore, cytotoxicity was evaluated by comparing the two anionic final covering layers alginate(Alg) and sodium cellulose sulphate(NCS) using MTT test. BPEI was excluded from the rest of the study due to its less capacity to strengthen the microcapsules and also the aggregation of the resultant alginate-BPEI-alginate microcapsules, while LPEI showed properties similar to PLL. MTT test also showed that NCS has no superiority over Alg as final covering layer. Therefore, it is concluded that, LPEI could be considered as a more cost effective alternative to PLL and a promising subject for future studies.

In this paper, we obtain approximate analytical solutions of the Dirac equation for the shifted Hulthén potential within the framework of spin and pseudospin symmetry limits for arbitrary spin–orbit quantum number κ using the supersymmetry quantum mechanics. The energy eigenvalues and the corresponding Dirac wave functions are obtained in closed forms.

Background: Nurses serve as the primary source of care for minor patients in intensive care units. Even though they support both patients and their relatives, these nurses may experience moral distress from their profession. While managing their daily relationships with their patients, nurses must also be able to control their actions to feel that they are from a social unit and feel their competence in association with ***: This study aimed to investigate the relationship between professional autonomy and moral distress among nurses working in children's units and pediatric intensive care wards. Methods: This descriptive/comparative cross-sectional study was conducted in 2015 using 120 nurses as subjects. Subjects were selected using the census method. The research tools used to gain measurable data were the Pankratznursing questionnaire(PNQ) and Corley'sMoral distress scale (MDS). In order to analyze the collected data, descriptive statistic tests such as the relative frequency distribution, mean, standard deviation and the Pearson correlation test, T-test, ANOVA, and regression were used. The SPSSv.20 software was also used to analyze the data obtained. Results: The relationship between professional autonomy and moral distress revealed that there was a significant positive relationship between professional autonomy and moral distress in the intensity (r=0.39;P<0.001) and the iteration (r=0.41;P<0.001). In addition, professional autonomy predicted 18% of changes in intensity of moral distress in total(MR = 0.42, R2 = 0.18) and also professional au-tonomy predicted 25% of iteration in moral distress in total(MR = 0.507, R2= 0.25). Conclusions: The results of this study revealed that there was a direct positive relationship between professional autonomy and moral distress.

Very recently, it was observed that the temperature of nanofluids is finally governed by second-order ordinary differential equations with variable coefficients of exponential orders. Such coefficients were then transformed to polynomials type by using new independent variables. In this paper, a class of second-order ordinary differential equations with variable coefficients of polynomials type has been solved analytically. The analytical solution is expressed in terms of a hypergeometric function with generalized parameters. Moreover, applications of the present results have been applied on some selected nanofluids problems in the literature. The exact solutions in the literature were derived as special cases of our generalized analytical solution.
