The patriarchal nature of African societies continues to shape women’s sexual behavior in the region. This in turn accounts for the high prevalence of HIV/AIDS among women in sub-Saharan Africa. Of the several factors implicated in the unequal prevalence of the disease among women in Africa, economic dependency/feminization of poverty, unequal distribution of sexual power (sexual violence and c...

The purpose of the hot rolling mill is to make a preheated steel block thinner and longer, see Figure 1. This is done by pulling the plate through two parallel rolls mounted in the rolling mill. Due to the large forces obtained in hot rolling, the elastic de ection of the rolling mill is of the same order of magnitude as the plate thickness. Variations in the rolling force caused by variations ...

HE spontaneous origin in 1926 of a tomato haploid in Lycopersicon Tescu len lun Mill. (LINDSTROM 1929) provided the source material of these investigations. This haploid when doubled asexually by the decapitation-callus method becomes an absolutely homozygous diploid ; and doubling this in turn results in the homozygous tetraploid. Selection experiments have been in progress since 1926 in the h...

Resin acids in many pulp mill effluents are primary sources of toxicity to fish. Inconsistent biological detoxification of chlorinated and nonchlorinated resin acids in secondary treatment of pulp mill effluents is a continuing source of concern. An alternative approach to effluent detoxification is to remove or modify the toxic compounds present in wood chips prior to pulping. Results from exp...

Thickness accuracy of plate production depends on Automatic Gauge Control (AGC) in the plate mill area. A typical modern thickness control system design and implementation of a steel plate mill is discussed together with the impact on the design of process models, available measurements, available control actuators and material properties. A highlevel software design approach provides the abili...

The finishing train of a hot strip mill has been modelled by using a constant volume element model. The accuracy of the model has been increased by using an Artificial Neural Network (ANN). A non-linear Rank Based Genetic Algorithm has been developed for the optimization of the work roll profiles in the finishing stands of the simulated hot strip mill. It has been compared with eight other expe...

Abstract: This paper applied the concept of “contact” in Differential Geometry into the machining of the sculptured surface. I presented the contact principle of the machining of complicated surfaces, using the circumference circle of the cylindrical cutter to sweep the curved surface instead of ball-end mill. This is highly effective method. In this paper an theory for machining complicated su...

Inventory is lifeblood in an organization. Multiechelon inventory of Olympia paper mill, Khyber Pakhtonkhwa is optimized by efficient management of the organizational supply chain (SC). A supply chain is designed starting from raw material receiving from supplier up to finished good delivered to the customer. The on-going setup of the selected organization is traditional based on the experience...

The Innovation Mill (IM) is an initiative which has been established in collaboration mainly among Nokia Corporation, Technopolis, and Tekes. Nokia Corporation provides its non-core ideas to other existing and start-ups companies through IM to turn these ideas into valuable products and services. Nokia idea database consists of enormous number of ideas that are non-core to it. Companies earn gr...
