THE PREVALENCE OF VITAMIN D DEFICIENCY: A COMPARISON STUDY IN TWO LIBYAN CITIES EXEMPLIFIED BY TARHUNA AND TRIPOLI

Vitamin D is a fat soluble vitamin, mostly made from 7 hydroxycholesterol in the skin with the aid of ultraviolet B radiation (UVB). Its function is facilitating the calcium and phosphorus absorption from the intestines that enables them to be transported among others to bones and teeth. In addition, maintaining the blood calcium homeostasis. Its deficiency leads to rickets and osteoporosis. This study aimed to analysis of the vitamin D levels in a randomized 2 samples in the two Libyan cities (Tarhuna & Tripoli) to contribute in the evaluation of the prevalence of vitamin D deficiency in the society. Therefore, vitamin D levels among 106 cases (52 from Tarhuna and 54 from Tripoli) were measured. Results of current study showed that 50 out of 106 cases (47.17%) were deficient in vitamin D, while insufficient vitamin D levels were found in 25 out of 106 cases (23.58%)

1 Generalized S-closed spaces and strongly S-closed spaces

This paper discusses both of S-closed spaces, strongly S-closed spaces and properties of them as well as the effect of some functions on them. This study focuses on show the relation between these spaces and the spaces that have closed cover.

The Impact of Accounting Information Quality at the level of performance. Applied Study on Libyan Banks

Abstract Purpose – the purpose of this paper is to examine the extent to which accounting information quality effects on banking performance. Design and Methodology – A primary survey was conducted on a sample of 54 managers who work in Libyan Banks, Tripoli City Finding – the result of this empirical study shows that accounting information system is positively associated with information quality (IQ) and mediates the indirect effect between the information quality and banks performance. More specific, system usefulness has an intervening impact on the relationship between IQ and Organization Performance (OP). While user satisfaction shows a great association with IQ, weak or low relation with OP compared with system usefulness. Research limitation – this paper was limited to the effect of IQ as an independent variable on AIS and OP on the Libyan banks. A cross-sectional study presented in this research can establish association but not causality. (PDF) The Impact of Accounting Information Quality at the level of performance. Applied Study on Libyan Banks.

Bifurcation and Stability of Reaction Diffusion Equations

The abstract theory applies to examples of algebraic equations and nonlinear boundary value problems are discussed, including systems of reaction diffusion equations. The link s between bifurcation and stability showing are also investigated, the study discusses how increasing a diffusion coefficient in a reaction-diffusion system can lead to bifurcation and also to a stable solution becoming unstable.

Assessment of Some Physico-chemical and Bacteriological Properties of Bottled Drinking Water in the Wadi Al-Shati Area Southern of Libya

The study was conducted to evaluate the quality of bottled water circulating in Wadi Al-Shati- Libya, and measured some of its physicochemical and bacteriological properties and its compatibility with Libyan and WHO standards. a total of 11 brands were selected for water analysis, the results of physicochemical analyses showed a difference in the quality of bottled water. The results of turbidity ranged from 0.84 to 1.04 NTU, while pH were between 5.63 and 7.45, while the TDS was between 28-303 mg/L, The TH was between 2-36 mg/L, the calcium was between 0.4-6 mg/L, magnesium ranged from 0.24-5 mg/L, and sodium was between 2-23 mg. Potassium ranged from 0.4-17 mg/L and chloride was between 1.3-45 mg/L, while nitrate was only 37 mg/L, and sulfate was between 0-73 mg/L. The bicarbonate ranged from 4-29 mg/L, while the iron ranged from 0-0.23 mg/L, manganese was the highest concentration of 0.19 mg/L, and zinc was only 0.11 mg/L, while the highest concentration of copper was 0.017 m/l, lead was not detected in all samples. The results showed that the total number of bacteria in bottled water ranged from 0-380 ufc /ml and there were samples that exceeded the permissible limits in the Libyan prescribing of bottled drinking water, while the results of the detection of colitis and fecal colon bacteria showed that all studied samples were free of fecal colon and coli , these results conformed to Libyan standards set out in the Libyan registration Drinking Water No. 10 for 2008.

Optimization of Calcium Carbonate Requirements in Rotary Kilns Lebda Cement Plant for Carbon Dioxide Emission Minimization

Cement industry has been one of the most carbon dioxide emissions in Libya. An optimization study has been conducted on calcium carbonate requirements in rotary kilns in Lebda cement plant. Optimization is carried out by a MATLAB computer program .The results showed that the optimum values of calcium carbonate ranged from (76 -76.5 wt%) in kiln feed, fuel consumption (8000-8200 m³/hr.) with minimum emission of carbon dioxide (690.3656- 699.8405 . Based on the results obtained from the process optimization, it is possible to minimize the CO2 emissions and reduce fuel consumption.

Note on closure operators of spical finite lattices

في الحالة العامة، مدى أي مؤثر غلاق على شبكة كاملة ليس بالضرورة شبكة جزئية من الشبكة الكاملة المعطاة، وعليه قمنا بوضع شروط لكي يكون مدى أي مؤثر غلاق على شبكة كاملة هو بالضبط شبكة جزئية. ثم وجدنا أن عدد كل الشبكات الجزئية المحتوية على العنصر الأكبر من شبكة خاصة منتهية هو بالضبط عدد كل المؤثرات الغلاقة على تلك الشبكة. أخيرا أعطينا صيغة لإيجاد عدد المؤثرات الغلاقة على هذا النوع الخاص من الشبكات المنتهية مع وضع أمثلة توضح هذه الدراسة.
