xGa1-xAs/GaAs superlattices. Using the transfer-matrix technique and the exact Airy function formalism, we investigate theoretically the effect of structural parameters on the electronic energy spectra of trimer thickness barrier (TTB). Our numerical calculations showed that the localization length of the states becomes more extended when the disorder is correlated (trimer case). We have also found that the resonant tunneling time (RTT) is of the order of several femtoseconds.
Drinking water is supplied to Danbatta, Makoda and some parts of Minjibir local government areas of Kano State from the surface water of Thomas Reservoir. The present land use in the catchment area of the reservoir indicates high agricultural activities, fishing, as well as domestic and small scale industrial activities. To study and monitor the quality of surface and drinking water of the area, water samples were collected from the reservoir, treated water at the treatment plant and potable water at the consumer end in three seasons November – February (cold season), March – June (dry season) and ples were analyzed for physical and chemical parameters, pH, temperature, total dissolved solids (TDS), conductivity, turbidity, total hardness, suspended solids, total solids, colour, dissolved oxygen (DO), biological oxygen demand (BOD), chloride ion (Cl – ) nitrite (NO2 – ), nitrate (NO3 – ), chemical oxygen demand (COD) and phosphate (POcuatro 3- ). The higher values obtained in some parameters with respect to the acceptable standard set by World Health Organization (WHO) and Nigerian Industrial Standards (NIS) indicate the pollution of both the surface and drinking water. These pollutants were observed to have a negative impact on water quality in terms of eutrophication, largely due to anthropogenic activities in the watershed. That it papers investigated the necessity for the introduction of business experience to possess Benue Condition University students. The people consisted of all step one,five hundred finally year pupils in the Benue Condition College. A sample out of 100 college students are chosen having fun with easy haphazard testing. A good a dozen-goods mind-constructed and you will articles verified survey from the research positives entitled, the need for the development of Entrepreneurial Skills during the Benue County College students (NDECBSUS) was utilized to collect the information and knowledge. The newest sugardaddy survey circumstances was in fact rated playing with a great 4-section modified score level out-of Highly Consent, Agree, Differ and you may Strongly Differ, tasked another an incredible number of 4,step 3,2 and you will 1, respectively. The fresh new survey is actually applied because of the researcher with a couple look personnel from the first provider. Simple proportions and you will chi-rectangular were used to resolve the study questions and you can test the fresh new hypotheses, correspondingly. Brand new conclusions revealed that in business management, organization management knowledge, individual skills, and technology event have to be developed in college students to them in order to become effective and you can productive entrepreneurs and determined that the purchase of those knowledge will reduce the trouble regarding unemployment. The research best if finance shall be produced from the every education stakeholders for like programmes to stay functional. Commercial Technology is actually a broad multidisciplinary field having intersections and apps in numerous parts. When designing something, it is critical to determine the correct attributes of worthy of and you can new taste function for which the item are optimized. This paper provides particular advice with the compatible selection of qualities to have liking and value attributes to own engineering framework. Has just, Big Open On line Courses (MOOCs) are becoming new development out of degree. There are many different troubles beneath the ecosystem out of Database Concept programs teaching techniques when you look at the MOOCs, for example teaching info and you may concepts which happen to be of reach into the fact, how to carry out the technology practise and entertaining habit from inside the the newest MOOCs environment, ergo the ways from databases path within the ecosystem away from MOOCs was suggested. You’ll find about three techniques to manage problem solving regarding the lookup, which are problems advised, issues fixed, and you may inductive investigation. Today’s research has the style of training contents, teaching procedures in the class room, flipped class room training setting under the ecosystem of MOOCs, learning flow method and enormous practice research. The fresh new database design function was methodically increased in line with the contrasting methods.56 The necessity for the introduction of Entrepreneurial Skills inside the Benue Condition Students, Makurdi
