Rationale: A spectrophotometer is an analytical instrument used to measure the transmission or reflection of visible light, UV light, or infrared light for quantifying solution concentrations. Despite the importance of the spectrophotometer as a precious analytical instrument, it has not been possible for many STEM science laboratories to access spectrophotometers due to their lack of funding. Creating a spectrophotometer with an Arduino microcontroller might demonstrate the possibility that low-cost assembling procedures can give insight into spectrophotometry and affordable accessibility for young scientists. Methods: An Arduino Uno was connected with an RGB LED and two light sensors that read the light intensity from two points, one from the front near to light input and the other from the back of the sample cuvette. A stepper motor could control the sample cartridge, which had 16 holders created with a 3D printer. The second Arduino Uno managed the stepper motor with an obstacle sensor to stop the cartridge at the exact sample reading point. The difference in the analog light intensity was recorded into variables for later calculating calibration curve with regression slope, intersection, and coefficient. Results: Using three colors of food dyes and serial dilution solutions, it was found that this automated spectrophotometer could accurately measure the sample concentrations within approximately 5.7% error from the actual concentration. The performance of the Arduino spectrophotometer was supported with the comparable regression coefficients being near 0.98 or so in measuring standard serially diluted dye solutions of the food dyes within the spectrum of the dye concentration. Conclusion: With 8 dye samples of blind test trials, no difference in the measured concentration was found for those from the samples with concentration created blindly.

The present populace of India is 1,362,255,678 as of January, 2019, in view of the most recent United Nations estimates [1]. Worldwide examinations calculate that there are 8.7 million individuals living with chronic Hepatitis in India. Chronic Hepatitis disease represents 12-32 per cent of liver malignant growth and 10-20 per cent of cirrhosis cases in India. The vast majority with constant Hepatitis B or C are ignorant of diseases and are at genuine danger of creating cirrhosis or liver malignant growth.Machine learning fits a few procedures superior to other traditional methods like Biopsy. This paper evaluate various machine learning methods to predict advanced liver fibrosis by using patient’s blood report to build up the optimization and classification models. The METAVIR score is a device used to assess the seriousness of fibrosis seen on a liver biopsy test from a human who has chronic hepatitis. Based on the METAVIR score [2,3,4] chronic hepatitis divided into three parts, first one is classified as mild stage, second one is moderate stage and third one is advanced stage of fibrosis. Grey Wolf Optimization, Random Forest Classifier and Decision tree procedure models forpropelled fibrosis chance expectation were produced. ROC curve and confusion matrix was evaluated to compare the accuracy of proposed methods.

House price has always been a hot issue concerned by the people. In recent years, the rapid growth of house prices across the country has become an important factor restricting economic development. Changsha has attracted much attention and reference because it has achieved good results in the regulation of the real estate market. By adopting the multiple linear regression model, we in this paper quantitatively analyze the factors that affect house prices in Changsha from four aspects: per capita disposable income, per capita consumption expenditure, total population at the end of the year, and investment in real estate development. It is helpful to grasp the development law of Changsha's real estate market and provide a certain reference basis for the regulation of the real estate market in other cities.

This study was carried out to determine the prevalence of intestinal schistosomiasis in the study population. The study was conducted in five selected primary schools in Kumo, Akko Local Government Area of Gombe State, Northeastern Nigeria between September and November 2019. A total of 250 specimens were collected and investigated for the presence of Schistosoma species using a standard medical atlas for the identification of the parasites. The specimens were analyzed microscopically. Out of the 250 samples examined, 26 (10.4%) were positive for S. mansoni. The prevalence was high in males accounting for 19 (73.1%) than in females 7 (26.9%). The prevalence was also high among the age group 10 – 12years 16 (61.5%) but there was no infection in the age group 1 – 6 0(0%). There is a significant difference between the primary schools, gender and ages of the pupils. However, there was no difference in their source of water. High infection was observed in those who use river and well water 10 (38.5%) and was low in those that use borehole water. These findings indicate the need for public awareness on the disease, routine chemotheraphy and implementation of vector control strategies, so as to avoid accelerated morbidity and inprove the health of people in the study area.

According to world health organization [WHO] medical records, malaria has a global fatality of 200 million people annually. Most of the victims are mainly children and expectant women. In this work a deterministic model has been developed to show the transmission of malaria. The model consists of ordinary differential equations (ODEs) which describe how malaria spreads. Existence of equilibrium points was analyzed and the key to the analysis was by defining the basic Reproduction number (R0). Numerical simulations was performed by MatLab solver.

Pneumatic multi-axis trailer is to be used mainly in construction and in industrial sites, where the space limitations are there. In this work, the material can be unloaded at any side of the trailer automatically by using ‘Pneumatic and Plc/Arduino Control’. Whereas in ordinary unloading is done at the backside only, here unloading is done in any direction. This system is totally operated with the pneumatic components with a linkage mechanism having the use of a chain-sprocket system. This work has been formed after studying the problem in unloading the materials. In small compact streets and small roads, it is difficult to unload the materials hence unloading angles are modified to unload the trailer in 0 to 270 degrees very easily. The effective use of ‘Pneumatic and Plc/Arduino Control’ is done. By pressing the Direction control valve, the compressed air goes to the pneumatic cylinder through the valve. The ram of the pneumatic cylinder used for lifting the trailer cabin. The rotation and other motions are achieved with the use of a chain drive mechanism. In this research an attempt is made to design and fabricate multi axis tilting trailer system embedded with pneumatic and Plc/Arduino control which may be useful to develop a mechanism for reducing time of loading and unloading, to provide easier way of dumping with less maintenance cost, to increase the efficiency of the vehicle and to reduce man power and also to achieve high safety, to reduce the work load and to reduce the fatigue of workers.

The traditional and indigenous knowledge on sustainable management and utilization of wild edible fruit bearing woody species is not well documented in Ethiopia. There are many plants species which are most popular and widely used for various socio-economic purposes including as supplementary food items and medicinal plants by local community. Wild edible fruit bearing woody species are highly inhabited on agricultural landscape and natural forests in which their diversity is threatened due to deforestation and forest degradation. Moreover, the traditional knowledge of using these wild edible fruit bearing woody species is being eroded through acculturation and loss of plant biodiversity in most of indigenous people. Hence, conducting research is crucial to generate useful information for ensuring food security and to maximize the socio-economic benefits through biodiversity conservation. This study was conducted to analyze socio-economic benefits of wild edible fruit bearing woody species and management under different use type in Dangur. A systematic sampling method was employed to locate the sample plots following the transect line in order to study the species diversity and socio-economic benefits, where the first transect line and plot were selected randomly inside the land use types. For wood land use type a plot size of 20 m × 20 m were used to encompass all edible wild fruit tree species inside the plots. For parkland agroforestry a plot size of 50 m × 100 m making a total of 144 plots were used for data collection. For socioeconomic study, 90 households were interviewed through structured questionnaire from three sample villages. Most prevalent species used as traditional medicine comprised plant families of Balanitaceae, Rhamnaceae and Apocynaceae under both woodland and parkland agroforestry types. The most frequently recorded species include Syzygium guineense, Ziziphus mauritiana. Ficus sur, Ficus sycomorus, Carissa spinarum, Balanites aegyptiaca and Gardenia ternifolia. From the recorded edible wild fruit woody species, fruits of 90% were trees that were most frequently used for different plant parts for various economical uses. Farmers retained edible wild fruit bearing woody species in their parkland agroforestry for the purpose of fuel wood, food, improving soil fertility, fodder, timber, shade and construction. The local communities employ management practices such as thinning, pruning and protection. The relative presence of high number of edible wild fruit bearing tree species in the study area is a good indicator of biodiversity conservation for food and nutrition and medicinal plants which needs good effort of in-situ conservation and applying of appropriate management practices.
在埃塞俄比亚，关于可持续管理和利用野生可食用果实木本物种的传统和土著知识没有得到很好的记录。有许多植物品种是最受欢迎和广泛用于各种社会经济目的的，包括作为当地社区的补充食物和药用植物。木本野生食用水果是农业景观和天然林中大量栖息的物种，其多样性因毁林和森林退化而受到威胁。此外，在大多数土著居民中，利用这些野生可食用果实的木本物种的传统知识正在被驯化和植物生物多样性的丧失所侵蚀。因此，开展研究对于为确保粮食安全和通过保护生物多样性实现社会经济效益最大化提供有用信息至关重要。本研究分析了丹古尔不同利用类型下野生木本食用果实树种的社会经济效益及管理措施。为了研究物种多样性和社会经济效益，采用系统抽样的方法，在土地利用类型内随机选取第一条样线和样地，沿样线定位样地。对于林地利用类型，地块面积为20 m × 20 m，包括地块内所有可食用的野生树种。林地农林业采用50 m × 100 m的样地，共144个样地进行数据收集。在社会经济研究方面，通过结构化问卷对三个样本村的90户家庭进行了访谈。在林地和公园农林业类型下，作为传统药物使用的最常见物种包括巴兰科、鼠李科和夹竹桃科植物。最常被记录的种类包括几内亚的紫唇虱和毛里求斯的紫唇虱。榕树、梧桐树、刺香树、埃及巴兰和栀子花。在记录的可食野果木本树种中，90%的果实是最常用于不同植物部位和各种经济用途的树木。农民在他们的公园农林业中保留了可食用的带有木本物种的野果，用于薪柴、食物、提高土壤肥力、饲料、木材、遮荫和建筑。当地社区采用诸如间伐、修剪和保护等管理措施。研究区食用野果树种相对较多，是食品营养和药用植物生物多样性保护的良好指标，需要在原地保护和采取适当的管理措施。

In this paper, we discuss theoretically the behavior of ideal Bose-Einstein gases in a 3D box and in a harmonic trap. We make use of the mean filed theory based on the time dependent Gross-Pitaevskii equation which describes the main features of Bose-Einstein condensation. We investigate and discuss the density profiles and the ground state properties of a trapped condensate confined in harmonic trap. We found out that in an attractive interaction, the gas tends to increase its central density in order to lower the interaction energy.

Nigeria as a sovereign state is currently passing through security challenges such that no one is sure which part of the nation is safe. Issues of unwarranted killings, insurgency, raping, domestic violence, kidnapping, armed banditry, broad day light robbery, cultism, human trafficking drug addiction, thuggery and so on which make our environment unsafe are common sights in Nigeria today. These crimes are at an alarming rate to the extent that they pose sleepless nights to most communities, government and other relevant authorities in Nigeria. While the government is making concerted efforts in tackling the menace of militant and terrorist groups like the dreaded Boko Haram jihadist, Indigenous people of Biafra (IPOB), movement for the emancipation of the Niger Delta (MEND) among others, the incessant herders versus farmers clashes, coupled with inter ethnic conflicts, are threatening the fragile peace of the nation. It is against this backdrop that this paper explores Theatre for Development (TfD) as an avenue for fostering security in the Nigeria state. Theatre for development (TfD) is a genre of theatrical exegesis that stresses development communication for the purpose of enlightenment through participation and critical consciousness for transformation. Theatre for Development (TfD) employs advocacy, dialogue and folk media in preparation, action plan as well as mobilization for transformational education.

作为一个主权国家，尼日利亚目前正在经历安全挑战，以至于没有人确定该国的哪个部分是安全的。毫无根据的杀戮、叛乱、强奸、家庭暴力、绑架、武装盗匪、光天化日之下的抢劫、邪教、人口贩运、吸毒、谋杀等问题使我们的环境不安全，这些问题在今天的尼日利亚很常见。这些罪行以惊人的速度发生，使尼日利亚大多数社区、政府和其他有关当局夜不能寐。虽然政府正在齐心协力应对恐怖组织的威胁，如可怕的博科圣地圣战分子、比夫拉土著人民(IPOB)、尼日尔三角洲解放运动(MEND)等，但不断发生的牧民与农民的冲突，加上种族间的冲突，正在威胁着国家脆弱的和平。正是在这种背景下，本文探讨了发展剧院(TfD)作为促进尼日利亚国家安全的途径。发展剧场(Theatre for development, TfD)是一种戏剧释经流派，强调通过参与和变革的批判意识来实现启蒙目的的发展交流。发展剧场(TfD)利用宣传、对话和民间媒体来准备行动计划和动员变革教育。这些都是通过研究、分析和戏剧化来完成的。本文将询问安全挑战的原因，如失业，贫困，犯罪，滥用药物，仅举几例。它还将审查这些影响以及如何在发展剧院(TfD)的帮助下解决这些影响。该文件除其他外建议，在一个受到安全挑战困扰的国家，沟通和对话仍然是解决冲突的最佳形式。
{"title":"FOSTERING NIGERIA SECURITY: THEATRE FOR DEVELOPMENT (TFD) AS TOOL","authors":"Inyanda Samuel, Atule Egwu Emmanuel","doi":"10.56557/jobari/2022/v28i17554","DOIUrl":"https://doi.org/10.56557/jobari/2022/v28i17554","url":null,"abstract":"Nigeria as a sovereign state is currently passing through security challenges such that no one is sure which part of the nation is safe. Issues of unwarranted killings, insurgency, raping, domestic violence, kidnapping, armed banditry, broad day light robbery, cultism, human trafficking drug addiction, thuggery and so on which make our environment unsafe are common sights in Nigeria today. These crimes are at an alarming rate to the extent that they pose sleepless nights to most communities, government and other relevant authorities in Nigeria. While the government is making concerted efforts in tackling the menace of militant and terrorist groups like the dreaded Boko Haram jihadist, Indigenous people of Biafra (IPOB), movement for the emancipation of the Niger Delta (MEND) among others, the incessant herders versus farmers clashes, coupled with inter ethnic conflicts, are threatening the fragile peace of the nation. It is against this backdrop that this paper explores Theatre for Development (TfD) as an avenue for fostering security in the Nigeria state. Theatre for development (TfD) is a genre of theatrical exegesis that stresses development communication for the purpose of enlightenment through participation and critical consciousness for transformation. Theatre for Development (TfD) employs advocacy, dialogue and folk media in preparation, action plan as well as mobilization for transformational education. These are done using research, analysis and dramatization. This paper shall interrogate the causes of security challenges such as unemployment, poverty, crime, drug abuse, to mention just a few. It will also examine the effects and how they can be addressed with the aid of Theatre for Development (TfD). The paper recommends among others that communication and dialogue remain the best forms of instrument for conflict resolution in a nation bedeviled with security challenges.","PeriodicalId":119621,"journal":{"name":"Journal of Basic and Applied Research International","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131434420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
