Original Research Paper Mathematics 1-Introduction : In the light of the progress and rapid development of the applications of research in applications fields, the need to rely on scientific tools and cleaner for data processing has become a prominent role in the resolution of decisions in industrial and service institutions according to the real need of these methods to make them scientific methods to solve the problem Making decisions for the purpose of making the departments succeed in performing their planning and executive tasks. Therefore, we found it necessary to know the transport model in general and to use statistical methods to reach the optimal solution with the lowest possible costs in particular. And you know The Transportatio

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

“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

Liquid membrane electrodes for the determination iron(III) were constructed based on chloramphenicol sodium succinate and iron(III) CPSS-Fe(III) as ion pair complex, with four plasticizers Di-butyl phosphate (DBP); Di-butyl phthalate (DBPH); Di-octyl phthalate (DOP); Tri-butyl phosphate (TBP); in PVC matrix . These electrodes give Nernstian and sub-Nernstian slopes (19.79, 24.60, 16.01 and 13.82mV/decade) and linear ranges from (1x10-5-1x10-2 M, 1x10-5-1x10-2 M, 1x10-6-1x10-2 M and 1x10-5-1x10-2 M) respectively. The best electrode was based on DBP plasticizer which gave a slope 19.79 mV/decade, correlation coefficient 0.9999, detection limit of 9×10-6 M, lifetime 37 day displayed good stability and reproducibility and used to determine

This research will cover different aspects of estimating process of construction work in a desert area. The inherent difficulties which accompany the cost estimating of the construction works in desert environment in a developing country, will stem from the limited information available, resources scarcity, low level of skilled workers, the prevailing severe weather conditions and many others, which definitely don't provide a fair, reliable and accurate estimation. This study tries to present unit price to estimate the cost in preliminary phase of a project.  Estimations are supported by developing mathematical equations based on the historical data of maintenance, new construction of managerial and school projects.

Jeder Lernende, der in der Fremdsprache Deutsch kommunizieren möchte, wird sich auch mit der deutschen Aussprache beschäftigen (müssen). Wer eine gute Aussprache hat, wird nicht nur oft und zu Recht bewundert, er hat es auch leichter, die deutsche Sprache zu verstehen, und er wird gut verstanden. Aussprachefehler beeinträchtigen die Kommunikation, sie führen zur Unverständlichkeit von Namen, Wörtern und Äußerungen oder Mißverständnissen, sie bewirken Ermüdung und Konzentrationsverluste und beeinträchtigen die Sprachverarbeitung durch Assoziationen und Emotionen, die beim Hörer entstehen können.’’[1]
