Thermo physical properties of Alates (Swarmers) termite wing has been investigated. The result of our investigation shows the values of thermo physical parameters of the sample materials as 0.0403Wm -1 K -1 being the mean thermal conductivity value, bulk density of 188. 8kgm-3 and thermal diffusively value being 8.2485 x 10 -8 m 2 s -1 . The values are within the values for commonly used insulating materials. Comparing the rate of cooling as well as heat absorption into the material as lagging material with the performance of fiberglass and cork, Alate's wing is adjudged to be a potential insulating raw material.

The effect of different concentrations of indole butyric acid (IBA) at 4g/L and 0.12/31.2 ml hardwood and semi hardwood cuttings of coratina olive was observed. Cuttings were taken in the month of February from coratina plant and dipped for 10 seconds in the required IBA solutions. The highest survival percentage, shoot formation, number of roots formation was maximum in 4g/L treated hardwood cuttings. The maximum numbers of branches were observed in hardwood cuttings as compared to softwood cuttings. It was concluded that either type of olive cutting treated with IBA solution 4g/L showed best results to propagate coratina olive.

The global poultry industry has experienced significant changes in the methods used to harvest and process the fresh egg over the past century. Applications of animal genetics and breeding have significantly increased in line speed for poultry operation. In this study aims at reviewing production factors that influence egg quality traits across the globe. The production factors so far utilized were classified into three main categories and presented based on their influencing capacity. For this purpose, two types of search criteria to find publications relevant to the scope of this review were employed. The first type was an automatic search performed on the following publishers' databases: ScienceDirect, Google's scholar, researcher gates, academia. The second type was a manual search on conferences, recent theses and dissertation that have not been published in journals from numerous Babcock University. Generally, 23 publications were reported for the breed; 17 for housing, and 19 for age of the breed after excluding studies that do not focus explicitly on breed, housing and age of the bird as production factors that influenced egg quality traits out of 183 potential relevant articles identified from January 2001 to December 2016. Thus, this review would provide animal genetics and breeding researchers in terms of identifying the most potent breed, adequate housing system and precise age for optimum production of birds with high quality.
在过去的一个世纪里,全球家禽业在收获和加工新鲜鸡蛋的方法上经历了重大变化。动物遗传学和育种的应用大大提高了家禽养殖的线速度。本研究旨在回顾影响全球鸡蛋品质性状的生产因素。将目前利用的生产要素分为三大类,并根据其影响能力进行了介绍。为此目的,采用了两种类型的检索标准来查找与本综述范围相关的出版物。第一种类型是在以下出版商的数据库上进行的自动搜索:ScienceDirect, Google的scholar, researcher gates,学术界。第二种类型是手工搜索会议,最近的论文和论文,尚未在许多巴布科克大学的期刊上发表。一般来说,有23篇关于该品种的报道;在2001年1月至2016年12月确定的183篇潜在相关文章中,排除了没有明确关注鸟类的品种、住房和年龄作为影响蛋品质性状的生产因素的研究后,17篇关于饲养条件,19篇关于品种年龄。因此,本文将为动物遗传学和育种研究人员确定最有效的品种,适当的住房制度和精确的年龄,以获得最佳的高质量家禽。

The study investigates the consequences of climate change on food security and environmental security in the Karamoja region of Uganda. It relates climate change to the conflict, insecurity and crises that have been witnessed in the region in the past years. It examines the implications of the change in the grazing pattern of the pastoralists and herdsmen in the time of recurrent drought and dry spells in Karamoja on the security of the region and other communities in Uganda and beyond. It relates the interplay of climate change, environmental security and food security to human security in Karamoja region. It also through focus group discussion (FGD) conducted in Kaabong District of the Karamoja region, identifies the presumed impacts of climate change on the environment and the people alongside its socio-economic implications. In the end, the study suggests proactive environmental security programmes in the Karamoja region which are expected to encourage sustainable mitigation and adaptation strategies in its communities, which will encourage its regional peace, security and stability.

In this study, macro and micro morphology of the leaves of Abutilon figarianum and Abutilon pannosum(Malvaceae) were compared to assist as a relevant source of information and contribute towards the standards to dispose the quality and identity of these plants to avoid adulterations. Laminar size, shape, marginal type, leaf length, width, petiole length, leaf base angle and leaf apex angle were observed and measured. The relationships were illustrated by differences of radar shape. Transverse sections of the leaves were done using wax method. Three regions from each leaf were sectioned apex, middle and base. The epidermises formed of one layer of small polygonal cells covered by mucilage, large numbers of epidermal hairs appeared. The two leaves are dorsiventral. The vascular bundles arch shaped surrounded by collenchymas and ground parenchyma. Xylem consists of radial rows of cells. The phloem is found beneath. The structures at the apex, middle and bases of the leaves are similar, trichomes are denser in the middle region followed by the upper and lastly the lower region. Calcium oxalate druses are appeared in some parenchyma cells of the mid rib region, and these are of large numbers in the basal region.

[0, 1] truncated fréchet-gamma and inverted gam-ma distributions [0,1]截断的伽玛和倒伽玛分布
Pub Date : 2017-10-30 DOI: 10.14419/ijsw.v5i2.8363
S. Abid, R. Abdulrazak
In this paper, we introduce a new family of continuous distributions based on [0, 1]] truncated Frechet distribution. [0, 1]] Truncated Frechet Gamma ([0, 1]] TFG) and truncated Frechet inverted Gamma ([0, 1]] TFIG) distributions are discussed as special cases. The cumulative distribution function, the rth moment, the mean, the variance, the skewness, the kurtosis, the mode, the median, the characteristic function, the reliability function and the hazard rate function are obtained for the distributions under consideration. It is well known that an item fails when a stress to which it is subjected exceeds the corresponding strength. In this sense, strength can be viewed as "resistance to failure." Good design practice is such that the strength is always greater than the expected stress. The safety factor can be defined in terms of strength and stress as strength/stress. So, the [0, 1]] TFG strength-stress and the [0, 1]] TFIG strength-stress models with different parameters will be derived here. The Shannon entropy and Relative entropy will be derived also.
本文在[0,1]]截断Frechet分布的基础上,引入了一类新的连续分布。[0,1]]截断的Frechet Gamma ([0,1]] TFG)和截断的Frechet倒Gamma ([0,1]] TFIG)分布作为特例讨论。得到了所考虑的分布的累积分布函数、第n阶矩、均值、方差、偏度、峰度、众数、中位数、特征函数、可靠性函数和危险率函数。众所周知,当一个项目受到的压力超过相应的强度时,它就会失效。从这个意义上说,力量可以被看作是“对失败的抵抗力”。良好的设计实践是这样的,强度总是大于预期的应力。安全系数可以根据强度和应力定义为强度/应力。因此,本文将推导不同参数下的[0,1]]TFG强度-应力模型和[0,1]]TFIG强度-应力模型。并推导了香农熵和相对熵。

Malaria remains a major health problem in Nigeria. It accounts for over 60% outpatient visit and 30% hospital admission in Nigeria. Ineffective treatment of malaria is also one of the factors responsible for its prevalence. The prevalence of malaria and treatment procurement was studied in Ekiti state, Nigeria. The study was carried out using well-structured questionnaire comprising of three sections A to C, Socio-economic, input and output data; data on method, cost of treatment of malaria and expenditure were obtained. Multistage random sampling technique was adopted. The result obtained showed that males with percentage prevalence of 53% were more infected than females with 47%. Respondent with symptoms of fever and chills was 48.2% while 51.8% complained of headache and pains. 80.3%% of the respondents have knowledge of malaria transmission while 19.7% have no idea. 46.7% of respondents spent less than 1000 naira for treatment procurement while 53.3% spent more than 1000naira. However, there was a significant difference (p<0.05) between males and female's susceptibility to malaria disease. Therefore, as at the time of study, there is prevalence of malaria in the communities despite the knowledge of the respondents on transmission of malaria and treatment procured.
疟疾仍然是尼日利亚的一个主要健康问题。它占尼日利亚门诊人数的60%以上和住院人数的30%。疟疾治疗无效也是导致其流行的因素之一。对尼日利亚埃基蒂州的疟疾流行和治疗采购情况进行了研究。这项研究使用结构良好的问卷进行,包括A至C三个部分:社会经济、投入和产出数据;获得了疟疾治疗方法、费用和支出方面的数据。采用多阶段随机抽样技术。结果表明,男性感染率为53%,女性感染率为47%。有发热、畏寒症状的占48.2%,有头痛、疼痛的占51.8%。有疟疾传播知识的占80.3%,不知道的占19.7%。46.7%的受访者在治疗采购上花费不到1000奈拉,而53.3%的受访者花费超过1000奈拉。男性和女性对疟疾的易感性差异有统计学意义(p<0.05)。因此,与进行研究时一样,尽管答复者了解疟疾的传播和获得治疗,但社区仍存在疟疾流行。

Impact of wrong sexual behavior of adolescent has been surveyed. It effect on the victims has been proven negative, with consequences like health effect including financial effect been a drawback, acting like a barrier to the ideal development of an individual adolescent. Wrong sexual behavior has been found to be on the increase, forcing adolescents to drop-out of school, exhibiting behaviors that do not conform to the development of the society. Result of this research findings shows the impact of wrong sexual behavior to include: Disregard for cultural/societal moral values, teenage/adolescent pregnancies, rapid increase in STDs and HIV/AIDS transmission, eagerness to practices illicit sexual acts, wrong conception about the opposite sex including sexual intercourse addiction with prostitution tendencies. The high positive percentages achieved from statistical analysis (respondent view-point) presents these impact as been on the increase, capable of dragging the society towards ruin. Recommendations of this study presents a view that the problem of adolescent wrong sexual behavior can be control , presenting guides like proper guidance and counseling , proper monitoring, aggressive sex education, reawakening of traditional African moral and value teachings, inclusion of sex education in religious teachings including proper dressing and restricting of adolescents from pornographic materials.
对青少年错误性行为的影响进行了调查。它对受害者的影响已被证明是负面的,其后果包括对健康的影响,包括对经济的影响,是一种不利的影响,对青少年个人的理想发展构成了障碍。错误的性行为越来越多,迫使青少年辍学,表现出不符合社会发展的行为。研究结果显示,错误性行为的影响包括:无视文化/社会道德价值观,青少年怀孕,性病和艾滋病传播迅速增加,渴望进行非法性行为,对异性的错误认识,包括性交成瘾和卖淫倾向。从统计分析(受访者的观点)中获得的高积极百分比表明,这些影响一直在增加,有可能将社会拖向毁灭。本研究的建议提出了一种观点,即青少年错误的性行为问题是可以控制的,包括适当的指导和咨询,适当的监控,积极的性教育,重新唤醒非洲传统的道德和价值教义,将性教育纳入宗教教义,包括适当的穿着和限制青少年接触色情材料。

In this study, Frechet distribution has been studied by using Bayesian analysis. Posterior distribution has been derived by using gamma and exponential. Bayes estimators and their posterior risks has been derived using five different loss functions. Elicitation of hyperparameters has been done by using prior predictive distributions. Simulation study is carried out to study the behavior of posterior distribution. Quasi quadratic loss function and exponential prior are found better among all.
本研究采用贝叶斯分析对Frechet分布进行了研究。后验分布是用gamma和指数推导出来的。使用五种不同的损失函数推导了贝叶斯估计量及其后验风险。超参数的推导是通过使用先验预测分布完成的。对后验分布的行为进行了仿真研究。其中拟二次损失函数和指数先验较好。
