FEMTOCELLS TECHNOLOGY DEPLOYMENT FOR IMPROVED QUALITY OF SERVICE IN MOBILE COMMUNICATION SYSTEM
Get PDFMobile technology has evolved exponentially interms of contents and subscriber growth within the past few decades. This evolution has come with its numerous value added services that are delivered to customers via legacy mobile communications networks that have little or no services within confined areas, homes and offices. This limitation together with high demands for services within indoor environment, have thrown a challenge to mobile operators and manufacturers to come up with solutions for addressing the poor Quality of Service (QoS). The concept offemtocells has been considered to be one of the available techniques for improving the degraded QoS within indoor environment. Femtocell is a compact portable low power home base station that can be connected via home internet access such as home digital subscriber line (DSL), fiber opticbroad band connection or any other available broadband connectivity to extend and improve mobile signal reception and also provide other wireless applications such as data, movies and pictures transfer. This paper provides an overview of femtocell technology applications and deployment scenarios for indoor environment that are characterized by multipath and attenuation which affects the performance of received signal hence degrading the QoS available to customers. Security and handover with in femtocell are also addressed

The Effect of a Combination of Soil Improvers and N, P, K Fertilizers on P-Potential, P-Available, P Uptake, and Rice (Oryza Sativa L.) Yield in Inceptisols Soil from Jatinangor
Get PDFInceptisols are an order of soil that has great potential to be used as productive land for rice cultivation because of its wide distribution in Indonesia. However, this land order has low soil fertility so it is necessary to fertilize to increase soil fertility. Balanced fertilization with soil improvers and N, P, and K fertilizers can be applied to increase fertilization efficiency. This experiment aims to obtain the dose of soil improver and N, P, K fertilizer that has the best effect on P-potential, P-available, P-uptake, and rice yield. The experiment was carried out from July to December 2023 at the Soil Chemistry and Plant Nutrition Laboratory Experimental Garden, Faculty of Agriculture, University of Padjadjaran, Jatinangor, Sumedang. The experimental design used was a Completely Randomized Block Design (CRBD) with seven treatments and four replications consisting of control; N, P, K recommendations; soil improver; ½ soil + ¾ dose of N, P, K; ¾ soil improver + ¾ dose of N, P, K; 1 soil improver + ¾ dose of N, P, K; 1 ½ soil improver + ¾ dose of N, P, K; 1 soil improver + 1 dose of N, P, K. One dose of soil improver is 8000 kg ha-1, while one dose of N, P, K fertilizer is 350 kg ha-1 Urea, 50 kg ha-1 SP-36, and 50 kg ha-1 KCl. The experimental results showed that the treatment of 1 ½ soil improver + ¾ dose of N, P, K was the best treatment for increasing the weight of 100 grains

Les inégalités d'accès à l'éducation des enfants en Tunisie
Get PDFLa sensation de privation, en particulier dans les premières stades de la vie de l'enfant, est négativement corrélée au développement physique et psychologique des ménages, menaçant sa survie et exerçant une influence sur ses opportunités sociales et professionnelles ainsi que sur son bien-être à l'âge adulte. Par conséquent, investir dans toutes les formes de privation des enfants et lutter contre toutes les formes de privation sont des moyens de surmonter les problèmes sociaux et les impasses des inégalités et de combattre la pauvreté transmissible entre les generations. Dans cet article, nous essayons d’étudier l’ampleur de l’inégalité des chances lorsqu’un certain nombre de circonstances indépendantes de la volonté de l’individu, telles que l’origine familiale, le sexe et le lieu de naissance, peuvent affecter l’accès à l’éducation de base des enfants tunisiens. D'importants déséquilibres d'inégalité persistent dans les zones rurales et des disparités régionales ont été détectées entre les régions côtières et intérieures de la Tunisie, même après la revolution. La zone de résidence, le niveau d’éducation du père et le sexe de l’enfant sont les variables qui contribuent le plus aux inégalités d’accès à l’éducation. Sans une intervention politique appropriée, la prochaine génération a quelques chances de surmonter ce piège d’inégalité
Metrics of Education and Politics are Important Correlates of Gender Gap: Evidence from Sub-Saharan Africa
Get PDFThe issue of gender inequality and the gender gap has been a longstanding concern globally. Numerous studies have examined various factors contributing to these disparities, including economic (UN, 2020), educational (UN, 2020; Dabla-Norris et al., 2015), health (Artiga et al., 2020), and political aspects (UN, 2020; Dabla-Norris et al., 2015). In the specific context of Sub-Saharan Africa, where gender inequality remains a significant challenge, understanding the correlates of the gender gap is crucial for developing effective policies and interventions
Core self-evaluation and loneliness as predictors of internet addictions among undergraduate students
Get PDFThe study investigated core self-evaluation and loneliness as predictors of internet addiction among undergraduate students, two hundred and forty-seven (247) undergraduate students which comprised 139 females and 108 males with a mean age of 21.76 and SD of 5.07 were selected using multi-stage (cluster, simple random: by balloting and purposive) sampling techniques as participants from Enugu State University of Science and Technology, Enugu. Young (1998a) internet addiction test (IAT), Judge et al., (2003) Core Self Evaluation Scale (CSES) and Russell, Peplau, and Ferguson, (1978) UCLA Loneliness Scale were used for the gathering of data, correlational design was adopted, while hierarchical multiple regression using Statistical Package for Social Sciences (SPSS) Version 25 was used for data analysis. Finding revealed that core self-evaluation did not predict internet addict at sig.= .836 which is higher than the threshold of at p< .05, loneliness also failed to predict internet addiction at sig. 556 which is higher than the value of at p< .05. The two independent variable shows no relationship with the dependent variable at r= .1(r= .079), both core self-evaluation and loneliness contributed 0% to the variation of internet addiction at r2= .006, both independent did not jointly predict internet addiction at sig. .752, which is higher than the threshold of at p< .05. Therefore, it is important to encourage students to develop a strong sense of core self-evaluation, as it can help them regulate their internet use and prevent addiction
ENGLISH LANGUAGE AND THE 21ST CENTURY SKILLS: ANALYSIS OF THE LESOTHO GENERAL CERTIFICATE OF SECONDARY EDUCATION SYLLABUS
Get PDFUnder the lens of 21st-century skills, this study examined the applicability of English Language instruction for the Lesotho General Certificate of Secondary Education (LGCSE), as well as its context in Lesotho, the world, and this period. The LGCSE English Language syllabus document was subjected to a qualitative document analysis. The findings demonstrated that a representation of each of the four ATC21s is available for each of the four aims proposed by the syllabus. In each aim, new methods of thinking, ways of living, ways of working, and ways of thinking arise. All goals appear to address 21st-century talents, according to these outcomes, which provide confirmation. The way these talents are represented in the four curriculum aims varies just a little. For example, all four of the goals included examples of communication, life, and professional skills. However, only aims 1 and 4 featured collaboration. Similar to this, aim 1, 3, and 4 solely considered critical thinking and metacognition as subskills. Only aims 2 and 3 have information literacy in them. Only aim 2 selected creativity and innovation. These findings offer corroborating proof and solidly establish the English Language as a legitimate subject with a place in the LGCSE curriculum.Learning ideas like heutagogy, which refers to managing learning for self-managed learners, can be utilized to design teaching and learning strategies that are in line with learners’ desire to choose their own goals and provide methods for achieving those goals
