The present work aims to study forward osmosis process using different kinds of draw solutions and membranes. Three types of draw solutions (sodium chloride, sodium formate, and sodium acetate) were used in forward osmosis process to evaluate their effectiveness with respect to water flux and reverse salt flux. Experiments conducted in a laboratory-scale forward osmosis (FO) unit in cross flow flat sheet membrane cell. Three types of membranes (Thin film composite (TFC), Cellulose acetate (CA), and Cellulose triacetate (CTA)) were used to determine the water flux under osmotic pressure as a driving force. The effect of temperature, draw solution concentration, feed and draw solution flow rate, and membrane types, were studied with respect to water flux. The results showed an increase in water flux with increasing feed temperature and draw solution concentrations In addition, the flux increased with increasing feed flow rate while the flux was inversely proportional with the draw solution flow rate. The results showed that reverse osmosis membranes (TFC and CA) are not suitable for using in FO process due to the relatively obtained low water flux when compared with the flux obtained by forward osmosis membrane (CTA). NaCl draw solution gave higher water flux than other draw solutions and at the same time, revealed higher reverse salt flux.
Find spins educational thought in the arguments of Imam Jafar Sadiq ( peace be upon him ), which is a valid approach to every age and generation , a fact the Lord's suitable for all ages, and a natural extension of the message the sky . Here was a project of Imam Sadiq ( peace be upon him ) for the breeding of individuals and the Islamic nation in general, so it was launched search to explain features of this educational thought when Imam Jafar Sadiq ( peace be upon him )

The Studying of historian aspects in Al-Hadieth books , such as " Al-Musnad Book " subjected to Al-Imam Abi Yalaa Al-mousily" ,has great importance in the field of Islamic history , in which Al- Al-Imam Abi Yalaa Al-mousily has presented valued information that have significant impact on the understanding of history, Have a significant impact on the understanding of Islamic history
(Abstract)
A man find himself in front of narrative literal productions when he read the title of this paper that deals with specialist , followers of Arabic literal narration productions through the era of Arabic literature in a period arrived to 1500 years. It is strange to present (Narration art in Arabic heritage) , in addition to (Arabic diwan) . This matter introduces us to come back to the past to inspect Arabic narration production , specially that is called (Artistic narration ) which is full ,variety of purposes and goals.
Computational linguistics is a modern branch of linguistics concerned with computer processing of natural languages. It makes computer as human brain simulate to human mind to understand language endoscopy and application. It stems from the use of computers to create programs and information systems that help the user to solve linguistic issues such as translation, analysis, parsing, and others This research seeks to show the employability of Arabic grammar, especially the past tense of it, in the light of this theory The study made use of the computer program (Madamera) to apply its samples of past phrasal verbs, In its methodology
