An Assessment of the Major Elemental Composition and Concentration in Limestones Samples from Yandev and Odukpani Areas of Nigeria Using Nuclear Techniques
I.O. Akpan,A.E. Amodu,A.E. Akpan
Journal of Environmental Science and Technology , 2011,
Abstract: These observations suggest that all particulate emissions and wastes from the Yandev deposit should be closely monitored to reduce its effects on the environment and health. The average Ca/Si ratio of the Yandev deposit is 4.32 while that of Odukpani deposit is 8.64. The observed low Ca/Si ratio in Yandev Limestone was attributed to the comparatively high Si content of the limestones. Thus the Odukpani limestone deposit appears to be more friendly to health and the environment.

Use of ICT Among Rural People in Oyo State, Nigeria
A.E. Adekoya
Research Journal of Applied Sciences , 2012,
Abstract: Information Communication Technology (ICT) is being used in different parts of the world to bridge the gap between the rich and the poor in terms of technology change and development initiatives. Provision of ICT for people s use has been through public and private commercial centers where various facilities and infrastructure are available for different purposes. Respondents in the study were mostly in late thirties and had formal education although very few had higher education. ICT usage was mainly for popular facilities like radio, television, telephone, video player and computer. Very few of the respondents were in the high user category although most fell in the medium perception class. Majority perceived the benefit from ICT as being moderate. Age and constraints had significant negative relationships with ICT use while perception and perceived benefit had positive significant relationships. Constraints experienced by respondents to use of ICT ranged from infrastructural to financial handicap. Many could not afford the use and some did not have the required education to handle the facilities.
Anton F. Prinsloo: Sleng: Woorde, uitdrukkings en hul herkoms
A.E. Cloete
Lexikos , 2011, DOI: 10.5788/17--609
Abstract: As die jongste toevoeging tot Anton Prinsloo se bruikbare naslaanwerke oor Afrikaans wat terselfdertyd aangename leesstof is, vul Sleng 'n leemte in die boekstawing van die Afrikaanse omgangstaal. Soos met o.a. Feite, flaters, fiksie: 'n Opgaaf van die ware, die onware en die onwaarskynlike (2001) en Spreekwoorde en waar hulle vandaan kom (2004) is Sleng nie alleen op taalpraktisyns gemik nie, maar is dit ook baie toeganklik vir die gewone taalgebruiker. Die boek bied eerstens 'n omvattende versameling woorde en uitdrukkings wat tans as om-gangstaal (en dus substandaard) gereken word, maar gee daarnaas ook die "korrekte" Afrikaanse ekwivalent en die Engelse vertaling daarvan. Interessan-te feite oor die herkoms van die slengwoorde en -uitdrukkings skep boonop die geleentheid vir 'n boeiende leeservaring.

The response of red duikers Cephalophus natalensis to drive counts
A.E. Rowland
Koedoe : African Protected Area Conservation and Science , 1990, DOI: 10.4102/koedoe.v33i1.451
Abstract: The response of red duikers to drive counts conducted on three consecutive days was monitored. The disturbance level to the duiker community of this counting method is low, an it is unlikely to have any long-term effects. The red duiker flees rather than hides from the counting line, thereby increasing its chances of being counted.

Numerical solution of multiband k.p
A.E. Botha
South African Journal of Science , 2010, DOI: 10.4102/sajs.v105i7/8.83
Abstract: A new and very general method was developed for calculating the charge and spin-resolved electron tunnelling in type-II heterojunctions. Starting from a multiband k.p description of the bulk energy-band structure, a multiband k.p Riccati equation was derived. The reflection and transmission coefficients were obtained for each channel by integrating the Riccati equation over the entire heterostructure. Numerical instability was reduced through this method, in which the multichannel log-derivative of the envelope function matrix, rather than the envelope function itself, was propagated. As an example, a six-band k.p Hamiltonian was used to calculate the current-voltage characteristics of a 10-nm wide InAs/ GaSb/InAs single quantum well device which exhibited negative differential resistance at room temperature. The calculated current as a function of applied (bias) voltage was found to be in semiquantitative agreement with the experiment, a result which indicated that inelastic transport mechanisms do not contribute significantly to the valley currents measured in this particular device.
Optimal Design of Hysteretic Dampers Connecting 2-MDOF Adjacent Structures for Random Excitations
A.E. Bakeri
International Journal of Engineering , 2012,
Abstract: The dynamic behaviour of two adjacent multi-degrees-of-freedom (MDOF) structures connectedwith a hysteretic damper is studied under base acceleration. The base acceleration is modeled asstationary white-noise random process. The governing equations of motion of the connectedsystem are derived and solved using stochastic linearization technique. This study is concernedon the optimum design of the connecting dampers based on the minimization of the storedenergy in the entire system. This procedure is applied on three models. The first is two adjacentthree stories buildings, the second is ten stories buildings and the third is ten-story buildingadjacent to twenty-story building. The connecting damper is installed in three cases; in all floors,double dampers in different floors, and single damper. The results show that at these optimumproperties of the connecting dampers, the response of each structure is reduced and the energyof the entire system is reduced.
