Using needs analysis as a research methodology, this study attempted to design a 20 hour academic writing (AW) course for Level 2 Foundation Year Saudi EFL students. Needs analysis was based on a diagnostic test, structured questionnaires, and researcher’s observation to obtain information on students’ language and skills needs, profile, levels of motivation, and learning styles and preferences. The results showed that the students did not have the writing proficiency for producing longer compositions and, therefore, the course should focus on appropriate language systems and skills to help learners with writing paragraphs based on two rhetorical strategies: cause and effect; and exemplification. The course content provides for the appropriate language systems and skills as voiced by the students and needed for writing these two types of paragraphs. The study also points to a course evaluation strategy that can be used for validation and future use of the proposed course.
Modeling the Evolution in the Concentration of Solids Based On Time of The Mewou River in the Mifi Basin (Published)
The objective of this study is to evaluate and model the evolution of the concentration of solids, as a function of the time of the Mewou river, in the Mifi watershed. We have determined from the samples taken from this watercourse and from the specialized laboratories the concentrations of soil exported. The MATLAB software allowed us to simulate the evolution of the concentration of solids, according to the time of this stream. This evolution is characterized by the polynomial model equation of degree nine with a correlation coefficient of 0.5702 and a coefficient of determination of 0.325: Cs = a* t 9 + b* t 8 + c* t 7 + d* t 6 + e* t 5 + f* t4 + g* t 3 + h* t 2 + i* t + j
Modeling the evolution of sediment discharge based on liquid flow rates of the Mewou river in the Mifi basin (Published)
The objective of this study is to evaluate and to model the evolution of sediment discharge depending on the liquid flow of the Mewou River in the catchment of the Mifi. The amount of exported soil was determined by oven drying of the water samples collected from the Mewou River at 105 °C. The MATLAB software has enabled us to simulate the evolution of sediment discharge based on liquid flow rates. The evolution of sediment discharge based on liquid flow rates obtained in this study is characterized by the polynomial model of equation nine degrees a correlation coefficient of 0.9999 and a determining coefficient of 0.9998:
Qs = a* Ql 9 + b* Ql 8 + c* Ql 7 + d* Ql 6 + e* Ql 5 + f* Ql 4 + g* Ql 3 + h* Ql 2 + i* Ql + j
This equation is more representative than the power model « Qs = a*Qlb » which has a correlation coefficient of 0.9891 and a determining coefficient of 0.9783 or the power model « Qs = a*Qlb + b » which has a correlation coefficient of 0.9934 and a determining coefficient of 0.9868 developed by other authors.
SELF AND STRONGLY SELF FUNCTION CHAINABLE SETS IN TOPOLOGICAL SPACES (Review Completed - Accepted)
In this paper the concept of self and strongly function chainable sets is
introduced for topological spaces. Results proved in  are extended to self and strongly
function chainable sets. Two characterizations of strongly function chainable sets have
been established in the paper. It is shown that the space is connected if and only if it is
function chainable provided the function is one to one
