El-agtal; Layla. M. E. Galala; Fathi. M. Abuogarad This paper investigated the effectiveness of installing Flexible AC Transmission Systems (FACTS) devices in the Libyan transmission network as an alternative to network reinforcement. The Libyan 220 kV transmission system is suffering from voltage stability problems especially in case of long transmission line and heavily loads in the southwestern networks.This work concentrates on the use of the application of reactive power compensation devices (FACTS) on the southwestern region networks .The focus of this work is to study the application of the reactive power compensation devices ( FACTS) on Libyan high voltage 220 kV and extra high voltage 400 kV electrical power network, as an effective alternative to network . In This paper a very integrated and comprises software tool designed for power system analysis and operation analysis and study were used. The package, named SPIRA was designed by (ENEL-CISE) of ITALY, and made available at General Electricity Company of Libya (GECOL).

Sadik; Yasein M. Kama; Mohamed A. Dow; Maged Hemid Background/ Objective: There is few data on the clinical grounds of brittle diabetic patients in Libya. Such patients are enormously costly in terms of health care resources in Libya. In this study we tried to determine the underlying etiologies as well as precipitating factors in brittle diabetic patients who were admitted to medical department in Ibn Sina Hospital, Sirte-Libya. Material and Methods: A retrospective study of all brittle diabetic patients admitted to the medical department in the period of March 2005 to February 2010. Patients age, gender, occupation, marital status, body mass index, hemoglobin A1c (glycosylated hemoglobin) concentrations, sub types of brittle diabetics and presence of diabetic complications as well as underlying causes were recorded. Results: A total of 7184 patients were admitted, 50 (0.69%), out of them were defined as brittle diabetics. The mean age was 28.58±12.16 years with male to female ratio of (1.1:5.1). Admission with recurrent ketoacidosis was the commonest subtypes of brittleness (62%) followed by recurrent hypoglycaemia (22%) lastly mixed brittleness16%. Depression was the common underling problem among patients with recurrent ketoacidosis (52%), mental retardation (28%), severe personality disorder (7%), stress reaction (7%), dementia (3%) and congenital anomaly of urinary tract (3%). Sheehan's syndrome was the most underling disease in patients with recurrent hypoglycaemia (28%), chronic renal failure (27%), Addison’s disease (18%), factitious hypoglycaemia (9%) and Shmidts (48%). According to occupational, 48% were students, housewife (30%), Teachers (6%), female office worker (6%), Nurse (4%) and jobless (4%).

Sasi; Abdulfattah M. Alkherraz; Mohamed A. Elsirkasi The research project aim is to determine the pKa of neopentanol alcohol because it has been used in many biological models as a leaving group. The pKa of neopentanol alcohol can be obtained by measuring the observed rate for compound 1 under identical conditions to that reported for a similar series of alkyl uridyl phosphate diesters. The pKa of neopentyl alcohol was derived from the reported Brønsted plot for the hydroxide-catalyzed hydrolysis of alkyl uridyl phosphate diesters and the observed rate constant for uridine 3´-neopentyl phosphate 1. As a result, the best estimate for the pKa of neopentanol alcohol can established from this work. The corresponding pKa of neopentyl alcohol from the observed rate of the hydroxide-catalyzed hydrolysis of 1 is 17.3, which is significantly greater than the value of 15.5 used in earlier reports. This new value can be used now to estimate a better half- life for pH-independent DNA cleavage. This allows us to use correctly the neopentyl group as a mimicked model for biological systems such as that in DNA cleavage Mon, 01 Dec 2014 00:00:00 GMT http://dspace-su.server.ly:8080/xmlui/handle/123456789/1524 2014-12-01T00:00:00Z http://dspace-su.server.ly:8080/xmlui/handle/123456789/1504 Some Properties Preserved by Cleavability Hassan K. Alzoghdani; Aghziel.E.M. Jellala; Saliema .F.R.Hussain In 1985 Arhangl' Skii introduced different types of cleavability as following:A topological space X is said to be cleavable over a class of spaces P if for ACX there exists a continuous mapping ƒ: X → Y € P such that ƒ-1ƒ (A) = A, ƒ(X)=Y.We study the case :If P is a class of topological spaces with certain properties and if X is cleavable over P then X € P Mon, 01 Dec 2014 00:00:00 GMT http://dspace-su.server.ly:8080/xmlui/handle/123456789/1504 2014-12-01T00:00:00Z
