In urban and peri-urban areas, wastewater and sewage sludge are used without prior treatment to fertilise vegetable soils. To this end, sewage sludge treated with market garden waste was tested to evaluate the morphological performance and yield of tomatoes. Thus, the composts based on faecal sludge and market garden waste are T0, T1 and T2 (for respectively T0: composted faecal sludge alone, T1: compost with 2/3 faecal sludge and 1/3 market garden waste and T2: compost with ½ sewage sludge and ½ vegetable waste).

Disability is a prevalent phenomenon. Disability issues in Bangladesh remain at the backside of the development agenda for a variety of reasons. People in general, view incapacity as a curse and a cause of embarrassment to the family. These forget bars Person with disabilities (PWDs) from participating in ordinary economic, social and political things to do in their families, communities, vital offerings and education, etc. The present study documented economic and social factors that impeded their access to health care, education, leisure activities, future life chances etc.

Background: The Insurance sector is ladened with the sole responsibility of risk bearing and management. This is very important to any economy especially the developing economies like Nigeria where there is absence or little presence of enabling environment for businesses, low life-expectancy and wavering government policies. It is also important for the Insurance sector to stay alive to perform the duty of rescuing the economy from peril. For the sake of sustainability, Insurance companies must decide on what processes to focus on to drive profitability.

The study aimed to investigate the impact of blended learning on students’ speaking skills of EFL learners through debate and extempore technique. The study used quasi-experiment which consisted of pre-observation, intervention and post observation. The total of 20 girls and 22 boys studying in grade 6 has participated in the study. The control group received traditional methods of instructions in English session whereas the experimental group received blended learning in special classroom. Both the groups were tested for their speaking skills before and after the intervention.

Subject description: Groundnuts (Arachis hypogaea L.) occupy an important place in traditional farming systems. However, yields in dry African savannas are less than one ton per hectare in extensive cultivation. These low yields are due, among other things, to precarious rainfall conditions, to the low distribution of improved varieties, but also to the non-development of local plant potential. In fact, compared to local cultivars, very few studies have been made.

This article presents the results obtained in the implementation of computer tools in the teaching of trigonometry in 11th grade at Liceu in Cabinda. Trigonometry is a branch of mathematics used to calculate the Earth's diameter, river widths, distances to make maps, pyramid measurements, algebraic calculations, among others.

Background: In the last years there were a huge differences in the ADL life style within Egyptian citizens by using transportation rather than walking, preferring to resting rather than moving and making sport. These changes in life style may reflect on the lower limb range of motion. Purpose:To have a standard normal value for lower limb's range of motion for Egyptian subjects. Materials and methods: 1000 normal Egyptian male and female subjects aged between 21 and 50 years, free from any conditions cause limitation joint mobility, enrolled in the study.

This article presents the results of a research carried out in the 2nd year students at ISCED in Cabinda, on the teaching-learning process of triple integrals with the integration of Maple Mathematical Software.

This article presents the results of a research carried out on the use of GeoGebra Mathematical Assistant in the teaching-learning process of differential calculus. This content deals with variation, movement, quantities that change and depend on other quantities, being considered by manypeopleasone of the great achievements of the human intellect. Differential calculus has a derivative concept considered fundamental for its study, as it is a linear operator, which forms a new function from the original, in which each point of the new function is the displacement of the original one.

Mechanical neck pain (MNP)affects approximately two thirds of the population in the middle age due to poor postural habits. Purpose: to compare the effect of pulsed electromagnetic field versus pulsed ultrasound on pain intensity, cervical range of motion and functional restriction in treating patients with MNP. Design: randomized controlled trial. Methods: 45 patients with MNP participated in this study.
