The major purpose of the study was to assess the causes, prevalence, and psychosocial impact of street life in Dessie town in the case of Arada, Piyassa, and Menaharia. The study was conducted in Dessie Town, southern wollo zone of Amara. The data for the study were obtained through questionnaires, interviews, and observation. The data was collected from 70 samples of children live on the street. The researcher has used a Snowball sampling technique. The researcher was employed descriptive design. To analyze the data both qualitative and quantitative research approaches are used. The result of this study shows that strict parenting, quarrel, conflict with parents, work seeking, peer pressure, and mental problems are significant causes for street life. Also, the level of street life in Dessie town was highly increasing. When we see the psychosocial impacts of street life, school dropout, physical abuse, psychological disturbance (feeling of loneness, anxiety, and fear), social exclusion, alcoholism, smoking, chewing chat were the significant psychosocial impacts of street life in Dessie town. Finally, the researcher recommended the correct measures to be taken as well as applying for collaborative work with the government, with nongovernmental organizations and with the local community.
该研究的主要目的是评估Arada、Piyassa和Menaharia病例中Dessie镇街头生活的原因、流行程度和社会心理影响。这项研究是在阿马拉南部沃罗地区的德西镇进行的。本研究的数据通过问卷调查、访谈和观察获得。这些数据是从70个街头儿童样本中收集的。研究人员使用了雪球取样技术。研究者采用描述性设计。为了分析数据,使用了定性和定量研究方法。这项研究的结果表明,严厉的父母管教、争吵、与父母的冲突、求职、同辈压力和精神问题是街头生活的重要原因。此外,德西镇的街头生活水平也在不断提高。当我们看到街头生活的社会心理影响时,辍学、身体虐待、心理障碍(孤独感、焦虑和恐惧)、社会排斥、酗酒、吸烟、咀嚼聊天是德西镇街头生活的重要社会心理影响。最后,研究人员建议采取正确的措施,并申请与政府、非政府组织和当地社区合作。

A Study on Bioadsorption of Synthetic Dye Using Guava (Psidium guajava) Leaves 番石榴叶对合成染料的生物吸附研究

Guava (Psidium guajava, white Indian) is common fruit bearing plant found throughout the Indian peninsula. It is said to be native to Mexico and Southern America and now can be found in many of the Asian countries. It is grown in tropical and sub-tropical region around the world. Guava leaves have shown many properties like antibacterial, bioadsorbent, etc. The bioadsorbent property can be exploited to remove coloured residues from water bodies. Problems like water pollution have arisen due to rapid industrialization and urbanization. Various harmful dyes like Coomassie brilliant blue, used in both textile industries and laboratories, are expelled into water bodies. To reduce the effects of such dye on ecology the research was carried out using guava leaves as bioadsorbent. That being the case the Coomassie brilliant blue solution at different pH was treated with guava leaf powder and the decrease in absorbance was noted at 625 nm. The Guava leaves were obtained from Mumbai suburban. The leaves were dried and powdered for further testing as bioadsorbent. All the chemicals have been used were of analytical grade. The study showed high absorption rate in acidic medium as the colour changed from dark blue to light blue. The optimum pH for bio-adsorption was found to be 3. As the amount of guava leaf powder increased, the rate of adsorption also increased. Guava leaf powder is effective as a bioadsorption as rate of adsorption increases with increase in guava leaf powder. With further optimization it can become potential source of adsorbent.
番石榴(Psidium guajava,白种印第安人)是一种常见的结果植物,遍布印度半岛。据说它原产于墨西哥和南美洲,现在可以在许多亚洲国家找到。它生长在世界各地的热带和亚热带地区。番石榴叶具有抗菌、生物吸附等多种特性。生物吸附性能可用于去除水体中的有色残留物。由于工业化和城市化的快速发展,出现了水污染等问题。纺织工业和实验室中使用的考马斯亮蓝等各种有害染料被排放到水体中。为减少该染料对生态的影响,以番石榴叶为生物吸附剂进行了研究。用番石榴叶粉处理不同pH值的考马斯亮蓝溶液,在625 nm处吸光度下降。番石榴叶是从孟买郊区获得的。将叶片干燥并制成粉末,作为生物吸附剂进行进一步测试。所有使用的化学品都是分析级的。研究表明,在酸性介质中,当颜色由深蓝色变为浅蓝色时,吸收率较高。生物吸附的最佳pH为3。随着番石榴叶粉用量的增加,吸附速率也随之提高。随着番石榴叶粉用量的增加,吸附速率也随之增加,具有较好的生物吸附效果。经进一步优化,可成为吸附剂的潜在来源。

The paper proposes a design and implementation of Van de Graaff generator whose output voltage is 80.28 KV. To calculate the generated output voltage we have use the sphere gap method. A Van de Graaff generator is an electrostatic generator as it works on a principle of electrostatics. A Van de Graaff generator is used to generate a high DC voltage. It was first developed by Robert Jemison Van de Graaff in 1929, in USA and carries his name along 1931. This generator uses a moving belt to build up very high voltages on a hollow metal globe which is located on top of the generator. The potential difference that is developed in modern Van de Graaff generator reach about 5 megavolts. A Van de Graaff generator that we design and built that is intended to be used in schools and colleges for teaching the basics principles of Electrostatics and Electromagnetics as well as many other applications. Nowadays many schools and colleges laboratories and many museums use this type of generators for electrostatics demonstrations.
本文提出了一种输出电压为80.28 KV的范德格拉夫发电机的设计与实现。为了计算产生的输出电压,我们采用了球隙法。范德格拉夫发电机是一种静电发电机,因为它是根据静电原理工作的。范德格拉夫发电机是用来产生高直流电压的。1929年,罗伯特·杰米森·范德·格拉夫在美国首次发明了它,并在1931年以他的名字命名。这种发电机使用一条移动带在位于发电机顶部的空心金属球上建立非常高的电压。现代范德格拉夫发电机的电位差可达5兆伏特左右。我们设计和制造的范德格拉夫发生器,打算在学校和大学中用于教授静电学和电磁学的基本原理以及许多其他应用。现在许多学校和大学的实验室和许多博物馆使用这种类型的发电机进行静电演示。

Aboveground Biomass Production and Nitrogen Content of Gliricidia Sepium under Different Pruning Regime- A Case Study at the Department of Agroforestry Farm (Kwame Nkrumah University of Science and Technology-KNUST) 不同修剪制度下滑石楠地上部生物量产量及氮素含量研究——以农林业农场(Kwame Nkrumah科技大学)为例

Gliricidia sepium is considered one of the commonly used multipurpose legume shade trees in Ghana. Different pruning regimes affect the nutrient content as the amount of biomass produced by many multipurpose trees. In this study, the aboveground biomass (both fresh and dry matter) production and nitrogen content in Gliricidia sepium under different pruning regimes (4, 8 and 12 weeks) was studied. The study was carried out in the demonstration farm of Department of Agroforestry in the Faculty of Renewable Natural Resources-KNUST. A total of nine (9) Gliricidia trees were selected. The pruning frequencies were assigned to the selected trees, after an initial pruning of 1.2m from the ground. The data collected include; new fresh weight, dry weight and nitrogen content at the various pruning time. Also, the amount of nitrogen (N) in the new biomass was estimated at each pruning time. The result shows that the aboveground biomass production increased from 4 weeks to 12 weeks regime. Overall nitrogen concentration increased from 2.61% to 3.58% upon reducing the pruning frequency from 4 to 12 weeks, and total nitrogen content was much higher in 12 weeks (36.01g) than in the other pruning frequencies, due to biomass production been larger. In conclusion, the study highlights the potential of Gliricidia biomass as a source of N and green manure for both agricultural and agroforestry purposes. Hence pruning regime of Gliricidia should be considered in managing it for nutrient and manure purposes.
在加纳,gliriicidia sepium被认为是一种常用的多用途豆科遮荫树。不同的修剪方式会影响多种用途树木的养分含量和生物量。研究了不同修剪制度(4周、8周和12周)下黄菖蒲地上部生物量(新鲜物质和干物质)产量和氮含量的变化。本研究在南京理工大学可再生资源学院农林业系示范农场进行。共选择了九(9)棵滑石树。在距离地面1.2m处进行初始修剪后,对所选树木分配修剪频率。收集的数据包括;不同修剪时间的新鲜重、干重和氮含量。同时,估算了各修剪时段新生物量的氮含量。结果表明:地上生物量产量从4周增加到12周;随着修剪频率从4周减少到12周,总氮浓度从2.61%增加到3.58%,总氮含量在12周显著高于其他修剪频率(36.01g),这是由于生物量产量较大。总之,该研究强调了Gliricidia生物量作为农业和农林业用途的氮和绿肥来源的潜力。因此,在对其进行养分和肥料管理时,应考虑对其进行修剪。

本研究调查了冈比亚在管理行为和领导风格方面的性别差异。首先考察了领导风格与管理行为之间的相关性,并对性别差异和领导风格进行了研究。然而,在收集目标受众的信息时,我们采用了定量的方法,使用了曼-惠特尼分析、交叉稳态分析和相关分析作为估计技术。从分析结果来看,在一个组织中,女性在变革型管理风格方面的频率最高,而男性在交易型领导风格方面的频率最高。研究得出的结论是,与女性领导者相比,男性领导者在管理职位上更受认可。
