The Effect of Gender and Social Class in Second Language Writing Style: Theoretical Review

This article aims to illustrate the effect of Gender and social class on second language writing style through reviewing related articles and studies. As well, it reviews different points of view for researchers who conducted similar studies. Analytically, the result of the current study reveals that writing style can be determined according to different variables that play a critical role forming the ideas and notions of writers. Gender and social class play an effective role in deterring writing style. The researcher recommends that learners must be taught to think in a critical and creative way while writing as well instructors have to add that a caring writer uses the critical thinking throughout the process of writing. Keywords: Gender, Social class, Writing style, Second languag

Prediction of the Values of the Chemical Constituents of the Gezira Groundwater Using GIS Techniques

This paper is concerned with establishing prediction models for the chemical composition of the groundwater in the Gezira area from the available recorded data. The area of study is approximately bordered by latitudes 13-15.6 North and longitudes 32-34.5 East.The inverse distance weighted (IDW) technique of the Geostatistical Analyst of the GIS has been employed to describe each individual chemical parameter of the Gezira groundwater by a mathematical continuous-surface function. The graphical representations of these mathematical functions in the GIS environment are eventually converted into colored-filled contours covering the whole area under study.The developed models can be used as primary predictors for estimating the expected values of the chemical constituents of the groundwater pertaining to any proposed drilling location in the Gezira area. The established GIS models are also used for the assessment of groundwater quality in the study area
