Soil gas radon Rn concentration was measured at 12 location in the Al-Qassim area, using radon gas analyzer-type Alpha GUARD 2000 PRQ from Genitron Instruments (Germany). In each location four different depths were taken for soil gas measurements, staring from the ground surface. The results suggested that the largest concentration was 340 ± 22 Bq/m for 60cm depth at in Al-Tarfia point sample P...

The "immune privilege" that inhibits immune defense mechanisms that could lead to damage to sensitive ocular tissue is based on the expression of immunosuppressive factors on ocular tissue and in ocular fluids. In addition to this environmental protection, the injection of antigen into the anterior chamber or infection in the anterior chamber induces a systemic suppression of potentially damagi...

The effect of long-term application of 4% atenolol eye drops has been studied in patients with either glaucoma or ocular hypertension. In some patients who show a good initial response the ocular hypotensive effect gradually wears off with long-term use. This pattern of response appears to be more frequent in patients with pretreatment intraocular pressure of 25 mmHg, or greater. In combination...

The Nova Stat Profile 1 analyser, a combined sodium, potassium, ionized calcium, haematocrit and conventional blood gas analyser, was evaluated over a four month period. In addition to assessing and demonstrating that the instrument met analytical requirements, an appreciation of the use of ionised calcium (iCa) was made. Prospective costs were characterised and practical problems of iCa measur...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...

Background: Behcet syndrome is a recurrent inflammatory disorder that frequently involves the ocular system. The purpose of this study was to determine the frequency of ocular involvement in cases of Behcet's disease in Babol, north of Iran. Methods: From April 2003 to December 2009, 100 cases of behcet's disease who were admitted at the Department of Ophthalmology and Internal Medicine of Babo...

Novel aluminised E-glass fibre reinforced unsaturated polyester composites, originally formulated for enhanced thermal and electrical shielding properties were evaluated in terms of their thermal performance. The thermal degradation of these specimens was analysed using a thermogravimetric analyser (TGA). The samples were heated from ambient temperature to 500 1C at a heating rate of 20 1C/min....

Abu Shquier Department of Information Science, University of Tabuk, Tabuk, KSA Email: [email protected] Abstract: Arabic stemming is a technique to find the stem or lexical root for Arabic words through the process of eliminating affixes (preffixes, infixes and suffixes) attached to their roots. Several approaches have been implemented to generate the stem of A...
