Aniline point is an indicator of chemical composition of motor gasoline and diesel fuel and of their aromatic and paraffinic contents in particular. A significant relationship between the research octane number of unleaded motor gasoline and its aniline point was investigated. This relationship was evident in particular in the case of aromatic and naphthenic compounds with higher octane numbers. A correlation equation with a correlation coefficient of 95% was found with an acceptable average error.

Research summary
تبحث هذه الدراسة في العلاقة بين عدد الأكتان لبنزين السيارات ودرجة الأنلين، وهي مؤشر مهم لمعرفة التركيب الكيميائي للبنزين ووقود الديزل. أظهرت الدراسة الإحصائية وجود علاقة قوية بين درجة الأنلين وعدد الأكتان المقاس بطريقة البحث، خاصة في أنواع البنزين التي تحتوي على نسب عالية من المركبات العطرية والألكانية. تم التوصل إلى معادلة بسيطة بعامل ارتباط 95٪ يمكن من خلالها حساب عدد الأكتان مباشرة باستخدام درجة الأنلين دون الحاجة إلى محرك، وكانت نسبة الخطأ مماثلة لفرق الإعادة في طرائق القياس المخبرية. تمت الدراسة على عينات من روح النفط والبنزين من معامل التحسين والتماكب في سوريا، وتمت معالجة المعطيات باستخدام برنامج الماتلاب. أظهرت النتائج أن العلاقة بين عدد الأكتان ودرجة الأنلين ممتازة في معادلة كثير الحدود من الدرجة الثالثة، مما يتيح التنبؤ بعدد الأكتان بدقة مقبولة باستخدام درجة الأنلين فقط.
Critical review
دراسة نقدية: تعد هذه الدراسة خطوة مهمة في فهم العلاقة بين عدد الأكتان ودرجة الأنلين، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة تعتمد بشكل كبير على العينات المحلية من سوريا، مما قد يحد من تعميم النتائج على أنواع البنزين الأخرى في الأسواق العالمية. ثانياً، رغم أن الدراسة تقدم معادلة دقيقة لحساب عدد الأكتان، إلا أنها تتطلب استخدام برنامج الماتلاب، مما قد يكون غير متاح لجميع الباحثين أو العاملين في هذا المجال. أخيراً، كان من المفيد تضمين دراسة مقارنة مع نتائج دراسات أخرى مشابهة لتعزيز مصداقية النتائج.

It is well understood that the productivity and thus the final yield of a crop are the result of several interacted factors, which have different effects on yield. This requires the determination of all factors affecting yield or other traits, the relationships among these factors, the value of correlation coefficient and the degree to which yield is affected by each of these factors.
This paper tries to examine the relationship between analogy and the grammatical rule. Analogy is one of the basic principles and bases of Arabic grammar during times of rule formation and judging it. Linguists were divided in their attitude to ana logy, with some supporting it and others against it. Grammarians were more inclined toward analogy than compilers, because grammarians’ research was based on the existing similarity between words, phrases, and style used in speech reported by tellers of what had been said by the Arabs. They based their rules and origins of analogy on that similarity. Analogists transliterated some foreign terms, Arabized, and derived new words out of them in a manner similar to that done with Arabic terms. However, some grammarians went very far in their excessive use of analogy to the extent that it becomes far removed from linguistic reality to be a form riddle and guessing, leading to reaction against analogy then against grammar. Analogy became an end in itself; it overlooked its original purpose; was then manifested in rule formation of words said spontaneously.
A study was conducted in Al-Assad University Hospital in Lattakia during the period February 2012 and February 2013 the study included a random sample of 97 patients (males and females) divided into three groups: the first group consisted of 16 patie nts with left atrial enlargement with no atrial fibrillation, the second group included 70 patients who had left atrial enlargement with atrial fibrillation, and the third group of 11 patients had atrial fibrillation with no left atrial enlargement. In the study the ECHO Doppler was used for measuring left atrial volume index (LAVI) through the Simpson method, this is in order to assess the role and relationship with the occurrence of atrial fibrillation. It was found out that three patients out of (16) from the first group about 18.75% developed an atrial fibrillation after one year of follow-up, which means that the left atrial enlargement gave a predication of the occurrence of atrial fibrillation. The continuation of atrial fibrillation was also noticed together with its lifetime with an increase in the size of left atrial after one year of following-up the patients of the second group. 3 out of (11) patients from the third group had an increase in the left atrial volume index at the end of the study 45.45% (P<0.001), Accordingly the atrial fibrillation could cause left atrial enlargement.Even though the left atrial enlargement may cause atrial fibrillation and vice versa according to thisstudy, the study shows the possibilities of existence of other variable factors related to atrial fibrillation whichplay a role in the occurrence.
The obtained results by hydrogeological and Tectonic survey related to fresh water resources in Al-Sin Basin, indicated that the fundamental aquifer of underground water in AL-SIN region belong to Jurassic. The alimentary basin of Al-Sin spring depen d upon filtration of rainfall water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation is toward west and south-west where we find flow place of Al-Sin spring and submarine fresh springs near seashore. Tectonical study shows the existence of fractures and fault groups with NE-SW, ENE-WSW and NW-SE directions. Groundwater movement has the same direction of fractures and faults NE-SW to ENE-WSW and Al-Sin fault structure which allow the existence of direct relation between principal Jurassic aquifer and secondary aquifer especially Cenomanian one.
Obesity is a widespread problem in all societies and it is accompanied with short sleep duration on the recent years especially after Media and communication has spanned, so many people will stay awake with TV and internet. For that, many researc hes were performed to catch evidence about the relation between short sleep duration and overweight .
