تعد درجة الأنلين مؤشرا مهماً لمعرفة التركّب الكيميائي لبنزين السيارات و وقود الديزل من خلال معرفة نسبة المركبات العطرية و الألكانية فيهما . و تبيّن الدراسة الإحصائية المجراة وجود علاقة مهمة بين درجة الأنلين و عدد الأكتان المقاس بطريقة البحث لبنزين السيارات و لاسيما أنواع البنزين التي ترتفع أعداد أكتانها و ترتفع فيها نسبة المركبات القارية (النفثينية و العطرية) . و قد أمكن من هذه الدراسة التوصّل لعلاقة بسيطة بعامل ارتباط ٪95 يمكن بها حساب عدد الأكتان مباشرة بالاستفادة من درجة الأنلين دون الحاجة إلى محرك و كانت نسبة الخطأ مماثلة لفرق الإعادة في طرائق القياس المخبرية .
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.

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 .
