A Cross Sectional Study: Availability of Improved Sanitation Facilities and Associated Factors among Rural Communities in Lemo Woreda, Hadiya Zone, Southern Ethiopia

Tadele Yohannes, Abdulalik Workicho, Henok Asefa
Background: Faecal-oral diseases represent the largest health burden associated with a lack of improved sanitation. Diarrhea is the most burdensome of these and accounting for over millions of deaths each year. Access to improved household sanitary facilities have great health benefits ranging from reductions in diarrhea, helmenth infections and trachoma through reduced risk of accidents and enhanced psychosocial well-being. Objective: This study was aimed at assessing the availability of improv...

The Influence of the Carbon Surface on the Rate of Copper Recovery from Slag of the Direct-to-Blister Process

Piotr Madej, Marian Kucharski
The study was devoted to the investigation of the influence of the carbon reducer’s surface on the rate of the copper removal (in the form of a copper-reach alloy, Cu-Pb-Fe) from the slag produced in the flash direct-to-blister process at the Glogów smelter in Poland. The slag used in this work was taken from the direct-to-blister Outokumpu flash furnace at the smelter in Glogów. Graphite penetrators of different surfaces were used as the slag reducer, and the experiments were carried out at 157...

Pre-Service Science Teachers’ Training: The Case of Colleges of Education in Nigeria

Jacob Kola Aina
Colleges of Education are teacher training institutions established to train teachers for primary and junior secondary schools in Nigeria. Research shows that science teachers trained in these colleges are not performing well in classrooms after their graduation. This is due to problems associated with Colleges of Education such as lack of science equipment, bad leadership, lack of committed lecturers and bad admission policy. These problems make teachers trained in these colleges to be incompet...

Toxic Effect of Imidacloprid on Protein Content in Estuarine Clam, Katelysia opima (Gmelin)

Madhura D. Mukadam, Arvind S. Kulkarni
The indiscriminate use of insecticide has caused serious pollution problems of aquatic ecosystems. Imidacloprid is mainly used to control sucking insects such as rice hoppers, aphids, thrips and some species of beetles. Further it is known to cause apathy, myatonia, tremor and myospasms in humans. Toxic effects of imidacloprid were estimated by selecting Katelysia opima as an animal model. Effect of imidacloprid on total protein content of gill, mantle, hepatopancreas, foot, male gonad an...

Background: One third of the world’s population constituting 2 billion people are infected with Tuberculosis (TB), which is the second most common cause of mortality amongst communicable diseases. Nigeria ranks fourth among 22 high TB burden countries. One of the major challenges to the control of TB is the presence and interaction of TB with HIV. In many parts of Africa, infection with HIV has further increased TB morbidity and mortality. To effectively control

Analysis on the Propagation of the Fiber-Optic Signals in the Perturbed Nonlinear Schrodinger Equation

Qianqian Xing, Jiuli Yin, Lixin Tian
Chaos appears in the whole process of fiber-optic signal propagation with one external perturbation due to the absence of damping. Via adding a proper controller, chaos cannot be suppressed when the controller’s strength is weak. With the increase of the controller strength, the fiber-optic signal can stay in a stable state. However, unstable phenomenon occurs in the propagation of the fiber-optic signal when the strength exceeds a certain degree. Moreover, we discuss the parameters’ sensitivity...

A Continuous Dynamical Systems Approach to Gauss-Newton Minimization

Roy Danchick
In this paper we show how the iterative Gauss-Newton method for minimizing a function can be reformulated as a solution to a continuous, autonomous dynamical system. We investigate the properties of the solutions to a one-parameter ODE initial value problem that involves the gradient and Hessian of the function. The equation incorporates an eigenvalue shift conditioner, which is a non-negative continuous function of the state. It enforces positive definiteness on a modified Hessian. Assuming the...

The various methods of remediation of contaminated soils include isolation, immobilization, toxicity reduction, physical separation and extraction. In this context, a noteworthy technique is vermicomposting, which uses worms to break down recent organic matter, turning it into a chemically more stable form able to retain metal ions, rendering them unavailable to the environment. To understand the transport of these elements in the soil, it is necessary to study their dynamics in the environment....
