The Geometry Of Commutative Symmetric Loops, Hussein M. Karanda
The Geometry Of Commutative Symmetric Loops, Hussein M. Karanda
Tanzania Journal of Science
The aim of this paper is to show the connection existing between a commutative symmetric loop and an euclidean space.
The Separation And Analysis Of Titanium And Iron In The Mineral Ilmenite, Adolf M Mulokozi
The Separation And Analysis Of Titanium And Iron In The Mineral Ilmenite, Adolf M Mulokozi
Tanzania Journal of Science
Since the location of extensive *ilmenite-bearing beach sands in Australia, and now in Tanzania, the separation and analysis of the mineral has become more important than ever. This is particularly because ilmenite has now become the principal source of rutile, an important product in the manufacture of pigments and ceramic materials. Ion exchange separation using a mixture of HCI and HF is described in the literature. The method has serious limitations especially when the use of glassware cannot be avoided. The author has successfully applied exclusively HCI solution for the anion exchange separation. The mineral was first brought in solution …
Electrochemical Machining (Ecm) With Alternating Current, S. J. Shine
Electrochemical Machining (Ecm) With Alternating Current, S. J. Shine
Tanzania Journal of Science
Electrochemistry has had several practical uses in industry for a long time; but one of the more recent applications is the machining of metals. Direct current ECM has been applied in industry for the last two decades. However, ECM with alternating current is still in the early stage of research and development. This paper shows that ECM with normal a.c supply is feasible and practicable if special tools are used. ECM with d.c. is first introduced to provide a better insight for the machining with a.c.
The Geometry Of Symmetric Loops, Hussein M. Karanda
The Geometry Of Symmetric Loops, Hussein M. Karanda
Tanzania Journal of Science
This paper is intended to deal with the geometry of locally analytic loops. In it we will show which loops generate symmetric spaces, the connection between the constructions of Sabinin and Loos, and examples of symmetric loops. The main results of these articles were published in 1972 (Karanda 1972).
An Iteration Formula For Finding Roots Of Equations, R. W. P. Masenge
An Iteration Formula For Finding Roots Of Equations, R. W. P. Masenge
Tanzania Journal of Science
We seek the roots of the equation f(x) = 0.
Studies In Artificial Rain: Their Progress And Prospects, P. B. Vitta
Studies In Artificial Rain: Their Progress And Prospects, P. B. Vitta
Tanzania Journal of Science
The progress made by studies of the phenomenon of rain is reviewed. Several techniques for modifying clouds so as to accelerate rain-drop precipitation are described.
The Surveillance Of Rodent Populations In East Africa In Relation To Plague Endemicity, S. Msangi
The Surveillance Of Rodent Populations In East Africa In Relation To Plague Endemicity, S. Msangi
Tanzania Journal of Science
Plague has been endemic in East Africa from very early times. The fact that the plague organism occurring in the area is mostly Pasteurella pestis var. antiqua which is said to have been associated with the Justinian pandemic of the 6th century A. D. would seem to support the contention that this endemicity was established during that pandemic. The maintenance of this endemicity has been made possible by the presence in the area of suitable rodent reservoirs, efficient flea vectors and favourable climatic and ecological conditions. The main reservoirs of plague in East Africa are Rattus rattus, Praomys natalensis and …
The Kunduchi Mangrove Basin, Alison Mccusker
The Kunduchi Mangrove Basin, Alison Mccusker
Tanzania Journal of Science
The pattern of tidal submergence and exposure in the Kunduchi mangrove basin is determined by contour mapping and by relating the contours to published tide predictions. Salinity of the creek effluent is measured at spring and neap tides in both wet and dry seasons. The vegetation of the basin, up to the highest high water level, is described briefly.
An Attempt To Control Boundary Layer Turbulence With Nonisotropic Compliant Walls, R. Grosskreutz
An Attempt To Control Boundary Layer Turbulence With Nonisotropic Compliant Walls, R. Grosskreutz
Tanzania Journal of Science
A review of turbulence production in boundary layers leads to a new approach to boundary layer control by means of nonisotropic compliant walls. Suitably constructed coatings were tested and demonstrate that the concept is basically valid.
