The University of Dodoma is a public university in central Tanzania located in Dodoma, the country's capital. Building is taking place on a 6,000 hectare site in the Chimwaga area about 8 kilometres east of downtown Dodoma.The University of Dodoma was formally established in March 2007 following the signing of the Charter by the President of the United Republic of Tanzania. The first academic programmes commenced in September 2007.In line with Tanzania’s Development Vision 2025, the University of Dodoma, when fully operational, will be able to enroll 50,000 students. This is more than double the size of the University of Dar es Salaam when UDOM opened. Wikipedia.

The Kabanga Ni-Cu sulfide deposits and the Luhuma Ni-Cu sulfide prospect are located in NW Tanzania roughly 200. km SW of Lake Victoria. Both areas are within the Meso-Proterozoic Karagwe-Ankolean tectonic domain, which consists of medium grade metasedimentary rocks, that are intruded by mafic to ultramafic intrusions, late syn- and post-orogenic granites.The two Ni-Cu sulfide deposits found in the Kabanga area are Kabanga Main and Kabanga North deposits; both of these deposits are associated with ultramafic rocks. The ore zones are classified into (1) those located within ultramafic rocks, (2) those detached from ultramafic rocks and located within metasedimentary rocks and (3) those located at the contact between ultramafic rocks and metasedimentary rocks.This paper focuses on the identification of element ratios (or lithogeochemical vectors) which could be used for target generation and prediction of mineralized zone(s) from the surface in order to avoid missing of ore targets due to complexities of leaching and trace element mobilization in soils.To do this, drill cores from Kabanga North and from Kabanga Main Ni-Cu sulfide ores were sampled. Core samples from the drill holes were selected in such a way that, at least each ore interval and associated lithologic units (ultramafic/metasedimentary rocks) were well represented. Core sampling was also undertaken in the Luhuma prospect. Soil sample lines were established in proximity of the sampled drill cores from Kabanga ore deposits and Luhuma prospect. Soil samples were taken and analyzed for trace elements.The most useful element ratios are (Pd/V) × 1000 and [(Pd/V)/(Cu/Cr)] × 100; V, Cr and Cu are in ppm and Pd is in ppb. These ratios were derived based on element variations in detached and contact ores. The results were corroborated by the Principal Component analytical data, which groups elements into clusters reflecting their host minerals, e.g. (1) Cr, V and Mo for oxides, (2) Ni, Cu and Pb for sulfides, etc. © 2011 Elsevier Ltd.

The growing interaction and interdependence between local cultures and modern science in the sphere of BATK should be encouraged in an equitable framework not only to maintain the sustainable development but also to produce umpteen numbers of innovations and inventions to the benefit of the society. But such marriage is needed to take into account the environment in which such knowledge systems are constituted. This study attempted to examine the experience of India and Kani tribe of Kerala in particular in the backdrop of the TRIPS and CBD. © 2010, RIS.

In the present paper, self-focusing of two laser beams, having equal frequency (wave number), propagating in cold, homogeneous and underdense plasma has been studied. The polarization vectors of the two beams are considered to be arbitrarily oriented, and lying in a plane perpendicular to the propagation direction. Using source dependent expansion technique, the evolution equations for spot size and phase shift of the laser beams having radial Gaussian profile, is derived. Numerical solutions for simultaneous evolution of the laser spot of the two beams have been obtained. © 2015.

There are two types of singularities in the linear thermoelasticity. The first one arises in the field of stresses if a force is applied to one point of the body. This singularity is physical and should be accepted. The second type of singularities is nonphysical and they arise in the fields of displacements and temperatures. There exist the nonlocal theories and gradient theories which have the goal to introduce the finite stresses instead of the infinite ones. The MAC model of the thermoelasticity is created to avoid the nonphysical singularities and it accepts the infinite stresses. MAC is the method of additional conditions, which allows introducing the new model to use the classical model, plus additional condition of the physical nonsingularity and/or condition of the good behavior of the solutions at infinity. The MAC Green s functions for the heat conduction and for the elasticity could be introduced using the differential MAC models. The infinite and finite bodies are considered. The principle of superposition is applied to obtain the integral equations to solve the boundary value problems. The strength criteria based on finite stresses could be changed in this model because the infinite stresses are allowed. The strength criteria based on deformations are applicable. Classification of MAC models is given.

Okinawa Island is located between mainland Japan to the northeast, Taiwan to the southwest and China to the west. In recent years, precipitation with relatively low pH has been observed in the island during winter seasons. This study was conducted to evaluate the potential sources and factors affecting distribution of trace metals in the atmosphere around the northern area of Okinawa Island. The results showed that the trace metal contamination was low comparable to rural areas of less industrialized countries. The annual average depositions were 6.0, 5.2, 4.4, 2.7 and 20.4kg km-2 y-1 for Al, Fe, Mn, Cu, and Zn, respectively. The metals in the precipitation were mainly derived from the dissolution of wind-blown soil particles. The distribution of trace metals across the island showed the influence of road traffic as a source and cause of atmospheric pollution. Aluminium and Fe were found to be high closer to the main road and decreased further away from the road, while Zn and Cu were strongly correlated with average mean pH of precipitation. The variation of concentrations in the island was attributed to the distance from the main road, average rain pH at a particular sampling location and wind speed and direction. A strong correlation between lithological elements (Al and Fe) and anthropogenic elements (Zn and Cu) indicates that they were carried by the same particles and experienced similar scavenging mechanism during dissolution process. © 2010 Elsevier B.V.
