Language ecology is the interactions between the environment and language. Such a discipline, ‘language ecology’ or ‘ecolinguistics has been founded by Einar Haugen’. Accordingly,  the study aims at qualitatively reviewing the theoretical and conceptual issues surrounding the subject of language ecology  by tracing the roots of language ecology. It further highlights the fundamental inconsistencies between how the concept of ecology is perceived in sociology and biology, and is applied to language, particularly, transposing the main central concepts of bio-ecology, such as relationship/interaction, environment, and organism to human language and theory of ecological-linguistic. The theory wavers among placing the focus

Tremendous efforts have been exerted to understand first language acquisition to facilitate second language learning. The problem lies in the difficulty of mastering English language and adapting a theory that helps in overcoming the difficulties facing students. This study aims to apply Thomasello's theory of language mastery through usage. It assumes that adults can learn faster than children and can learn the language separately, and far from academic education. Tomasello (2003) studied the stages of language acquisition for children, and developed his theory accordingly. Some studies, such as: (Ghalebi and Sadighi, 2015, Arvidsson, 2019; Munoz, 2019; Verspoor and Hong, 2013) used this theory when examining language acquisition. Thus,

      In the present paper, the features of democratization of vocabulary in the language of mass media are tackled. Particularly, the functions of this phenomenon in the context of language as an ontological reality are analysed. As well, the growing role  of the language of the media, and the language of politics as an integral part pertaining to it, is noted. Further, attention is paid to the excessive saturation of the language of the media along with the literary language, by means of evaluation which may include negative results.

     In this concern, scholars had different views, specifically in relation to the use of colloquial vocabulary along with some vernacular profess

“El bilingüismo como fenómeno mundial”
Desde el ámbito lingüístico que define : ―Las lenguas son sistemas de símbolos diseñados para comunicación” ( 1 ) . Aparece la competencia lingüística ,es decir el bilingüismo es la capacidad de utilizar dos lenguas o más de forma alternativa y las personas implicadas se denominará bilingües, este fenómeno se extiende para comprender las comunidades lingüísticas, por eso la mayoría de los países del mundo son oficialmente bilingües o multilingües , en el sentido tiene dos o mάs lenguas nacionales o regionales oficialmente reconocidas .Algunos países forman ejemplos más destacados del bilingüismo como Άfrica ,Asia,Europa,Oceanía ( 2 )
,America. El propósito d

The research is based on the most important pillars: 1 - constructive towards the Arabic language, functions, and branch into synthetic functions and deliberative functions and internal functions and external functions.
2. Expression, rank, sentence, and patterns (association sentences and compound sentences)
3 - linguistic heritage and modern functional lesson and is based on 1 - heritage and the optimal theory. 2. Heritage function. 3. Theory of optimal theory. 4. Heritage as a reference, history, and source.
4 - discourse: patterns and characteristics - stereotyping discourse - a structure of the discourse - components of discourse.
The first pillars of the use of language start from the fact that the language is a set of

In this study the Entrance Surface Dose (ESD) received by pediatrics patients undergoing chest, abdomen and skull X-ray examinations was estimated. The study was conducted in two hospitals in Najaf city where three radiographic systems were considered. The study participants were classified into four age groups 0-1 ,  1-5 ,  5-10  and  10-15  years. Calculations were performed using exposure factors, kVp, mAs and focal-skin distance, together with patient data age. The ESD was calculated for the involved patients who underwent an Antero-posterior (AP) chest, abdomen and skull X-ray examination. The resulted data were analyzed and compared with international dose references. For all studied radiographic examinations and all X-ray mac

A set of ten drug compounds containing an amino group in the structure were determined theoretically. The parameters were entered into a model to forecast the optimal values of practical (log P) medicinal molecules. The drugs were evaluated theoretically using different types of calculations which are AM1, PM3, and Hartree Fock at the basis set (HF/STO-3G). The Physico-chemical data like (entropy, total energy, Gibbs Free Energy,…etc were computed and played an important role in the predictions of the practical lipophilicity values. Besides, Eigenvalues named HOMO and LUMO were determined. Linearity was shown when correlated between the experimental data with the evaluated physical properties. The statistical analysis was used to analy
