يهدف هذا البحث إلى مقارنة دقة قياسات العدسة المزروعة داخل العين باستخدام معادلتي Hoffer Q و Haigis عند المرضى ذوي الطول المحوري القصير للعين ومعرفة إذا ما كانت هذه المقارنة ستختلف باختلاف عمق البيت الأمامي .
This research aims to compare the accuracy of the measurements of the implanted intraocular lens using the Hoffer Q and Haigis equations in patients with short axial length of the eye and to see if this comparison will differ according to the depth of the anterior chamber.

This study represents the problem of the invariant sub-groups of the
maximal solvable invariant sub-groups in a group GL(q,p), with p and q are
primes, q|(p-١), and its order is r with r/| (P − 1) , as the studying of its
normalizer groups and ide
ntification the order of the normalizer for each one
in the case r is an odd order, and also with studying the problem of its
conjunction in a group GL(q,p).
Purpose: to assess the efficiency of topical anesthesia in
phacoemulsification with IOL implantation.
Department of Ophthalmology, Muasaa Hospital. The research was carried on 56 eyes of 48 patients.
The experiment was carried out to study the ability of Cu and Zn
adsorption on natural Zeolite using six concentration of Cu and Zn
(50, 100, 150, 200, 250, 300) mg.L-1 and two different diameters
of Zeolite particles (0.5mm-1mm). The research aim
ed to define
the ability of Freundlich and Langmuir isotherms equations.
specifically coefficient R2 was used to determine the suitability of
these isotherms.
Purpose: to study the Distribution of intraocular pressure in the age group 20-40 years old and the related factors: age, gender, family history, BMI, smoking.
Methods: This was a population-based cross-sectional study of 1000 subjects All particip
ant underwent IOP (intraocular pressure) measurement and a standardized survey for the initial data of the study.
Results: The mean IOP for the study subjects was (17.6mmHg); the mean IOP in men was higher than women (17.53) vs (16.8) mmHg respectively. Ocular hypertension was found in 16.8% participants. IOP increased 0.5 mmHg for every 10 years of age. BMI (Body Mass Index) had a positive association with IOP. Subjects with positive family history of ocular hypertension had higher IOP (18.46) vs (16.98) mmHg. IOP was higher in smokers’ group (17.77) vs (16.29) mmHg. Multivariate analyzing showed that aging, smoking, male sex, family history were independent risk factors for ocular hypertension, otherwise there was no significant relationship between ocular hypertension and BMI.
This research was conducted in Alkallouf village in Lattakia Province on grapevine trees belonging to local varieties Shami Abiad (Local) and Tuffahi in Vitis vinifera L. species grown on 10 years Arbor training grafted on B41 rootstock and planted i
n 3x3m during 2013 and 2014. And results were as follows:
The best fertility of winter eyes in Tuffahi Local variety were between 0.11 and 1.37 as an average. The tenth eye on a stock has achieved the highest economical fertility (1141.25 g) as a main for 2013 and 2014, and was significantly better than other winter eyes.
The best fertility of winter eyes in Tuffahi Local variety was tenth eye which achieved (1.24) during 2013 and 2014, were fertility was less on first eye (0.33). An eye number ten was significantly better than other winter eyes except an eye number nine which achieved (1.13) fertility.
An eye number ten has achieved the best economical fertility (the main weight of cluster 2137.75 g in two years study) followed by an eye number nine (1338.05 g). An eye number ten was significantly better than other studied winter eyes.
