ABSTRACT: Examination malpractice and student impersonation is a rising concern in tertiary institutions of learning in Nigeria. Majority of the students nowadays involve in the examination malpractices. Examination monitoring is one of the major approach to ensure quality assurance of school products (graduates). A qualitative examination monitoring will have zero tolerance to examination malpractices. The current method of monitoring of examination in the various school which are manual is...
Abstract: Around 80 % of the people of Ethiopia are estimated to be relying on medicinal plants for the treatment of human and cattle ailments. The purpose of this study was to collect, identify and document ethnomedicinal plants and associated indigenous knowledge of communities of the study area. Ethnomedicinal data were collected by using semi-structured interview, focus group discussion and direct field observation with 54 randomly selected non-healers (Female 27 and Male 27) and 46 trad...
Abstract: The first experimental observation of spin-orbit (SO) coupling in Bose Einstein Con densates (BECs) provided an interesting new platform to explore a fascinating and growing field of research and lead to rich physical e↵ects. In ultracold atomic sys tems,the synthetic SO coupling can be generated using two counter-propagating Ra man lasers that couple two hyperfine ground states. Motivated by these experimental findings, some theoretical activities have been committed to the phys...
Abstract: The experiment was conducted at Haramaya University Beef fattening station, to evaluate the effect of maize silage inclusion at different levels on feed intake, growth performance, carcass characteristics, and meat quality. Twelve castrated Harar oxen of average age 6 years with the initial body weight of 229±1.18 kg (mean+SE) were used for the experiment. The animals were randomly distributed to four treatments each with three replications in a completely randomized design. The d...
Abstract: The present work is an attempt to assess the effect of crustal contamination through the Granitoids host rock, within the southern Bastar mafic dykes of Chhattisgarh, India, in the light of geochemical characteristics. Petrographically, these dykes are classified as Amphibolite, Dolerite/Meta-Dolerite and Diorite. Geochemically, all dyke samples have been classified as “high iron sub-alkaline Tholeiites”. On account of overlapping magnesium and iron concentration in Amphibolite...
Abstract: Water disinfection is a crucial water treatment process because it deals with the removal of pathogens to make water safe to drink. Moringa oleifera extract was used as a disinfectant and the total coliform count was monitored through microscopic observations. The total coliform bacteria removal at a dosage of 5 ml/100 ml of Moringa Oleifera extract was counted to be 13 colonies from an original count of 200 colonies, translating to about 93.5% removal of the bacterial strains. The...
Abstract: Movement restrictions introduced by the coronavirus pandemic have incentivized the rollout of online services globally. Additionally, more employees were telecommuting throughout the pandemic and remote work has become the new normal. This has provided nefarious actors with lucrative opportunities. Hence there has been an increase in online criminal and terrorism activities. The weaponization of the cyberspace is also a concerning trend in the ongoing geopolitical tensions. This is...
Abstract: Nanomaterials have been used recently in food packaging as antibacterial coatings because of their desirable antibacterial and antifungal properties. The use of antimicrobial packaging is to deter the growth of microorganisms responsible for spoilage or diseases in packaged foods, therefore prolonging their shelf life. In this study, potato peel starch and ZnO-starch nanocomposite paper (ZnO-starch NC paper) were developed and evaluated for antibacterial activity against Esche...
Abstract: Vetiver grass (Chrysopogon zizanioides;CZ) is a well-known grass that can both remediate various heavy metals in soil as well as producing essential oil that is commonly used in premier perfumery, food and pharmaceutical industries. Due to this versatility property, this study was aimed at extracting essential oil from Chrysopogon zizanioides roots cultivated in SelibePhikwe mine tailings and study the quality and quantity (chemical composition and yield) of the Chrysopogon ziza...
Abstract: The dynamical behavior and the synchronization of epileptic seizure dynamics, with fractional-order derivatives, is studied in this paper. Knowing that the dynamical properties of ictal electroencephalogram signal recordings during experiments displays complex nonlinear behaviors, we analyze the system from chaos theory point of view. Based on stability analysis, the system presents three equilibrium points with two of them unstable. Moreover, the system reveals attractor points fr...
Abstract: We start by considering the theory of electromagnetic waves, from the Maxwell’s equa tions, the extended (1+1)D complex Ginzburg-Landau equation, higher-order nonlin ear Schr¨odinger equation are derived with the third, fourth, fifth and sixth-order dis persions and the cubic, quintic, and septic nonlinear terms, describing the dynamics of extremely short pulses in nonlinear undoped and doped optical fibers. The linear stability analysis is employed to extract an expression for ...
Abstract: We study the mutual effects of neuronal electrical activity and DNA dynamics in a network of electrically coupled neurons with nearest neighbors communication. For that we develop by means of the coupling function method, a mathematical DNA-neuron model that can be considered as an extension of the simplified Hodgkin-Huxley models. Numerically, we explore the biological properties of the model with emphasis on local phase transitions and synchronous neural activity. Our results sug...
Abstract: This study proposes a new electroencephalography (EEG) biometric authentication for humans based on eye blinking signals extracted from brainwaves. The brainwave signal has been investigated for person authentication over the years because of its difficulties in spoofing. Due to advancing low-cost EEG hardware equipment, it has recently been significantly explored. Most studies in brainwave authentication focus on the use of imagination and mental task to authenticate a subjec...
Abstract: The ever-increasing population growth and economic developments have heightened demand for energy. This has resulted in depletion and ever-rising prices of petroleum diesel, thus increasing environmental degradation. These complications have motivated this study for the search of an alternative eco-friendly and renewable source of energy such as biodiesel. Biodiesel has been found to be a potential alternative fuel for diesel. Biodiesel was produced by transesterification reaction ...
Abstract: The multidimensional nature of dengue virus (DENV) infections, which can be caused by four distinct serotypes of the virus, complicates the sensitivity of assays designed for the diagnosis of infection. Different viral markers can be optimally detected at different stages of infection. Of particular clinical importance is the early identification of infection, which is pivotal for disease management and the development of blood screening assays. Non-structural protein 1 (NS1) is an...
