The theory of operation on both sides of stoichiometry of a miniature zirconia oxygen pump-gauge incorporating a diffusion hole is discussed. Computer simulation of the sensor output when used for monitoring the air-to-fuel ...

Deposition of the Arab Formation on the Arabian Plate followed a eustatic sea-level high during the Oxfordian that deposited the open-marine shelfal carbonates of the Hanifa and Jubaila Formations. Oolite/peloidal shoals ...

Qatar, one of the Arabian Gulf States, possesses one of the world's largest non-associated gas fields. Most of the country's development plans are based on the preparation of natural gas for export and local use. Under ...

Positron annihilation lifetime technique has been applied to study the microstructure change in steel after heat treatment. For this purpose, the specimens are heat treated in various manners; normalizing, annealing, ...

Spreading of oil on calm water is analyzed for the second stage of spread, which is controlled by a balance between gravity and viscous forces. The analysis, using the integral boundary-layer method, agreed well with a ...

This paper demonstrates the application of fuzzy systems and Z-transform for electric load modeling in the presence and/or absence of harmonics. The problem is formulated as one of linear optimization, where the objective ...

Four Hemiurids collected from some marine fishes caught off Qatari waters int he Arabian Gulf are described and compared with related species previously reported from the Arabian Gulf and the Indian Ocean. These include ...

The capabilities of the voltage stability security assessment (VSSAD) to assess proximity to and ranking voltage instability by (a) performing a contingency selection of each model determined subsystem and (b) diagnosing ...

لا شك أن نسيان الإنسان لبعض الغيب الماضي من صالحه في دنياه وأخراه، فهناك العداوات والمظالم التي وقعت بين الأصول، وبين الدول والقبائل والشعوب، لو لم تطو صحائها، وتندثر معالمها، ولو لم تنس في بطون التاريخ وغابر الأزمان لكانت ...

الخلاصة : أن فكر مالك بن نبي يمثل ثقافة مزدوجة عالمیة : إسلامیة وغربیة ، وبحكم سعة أفقه وعمق تفكیره وثبات عقیدته ، استطاع أن يستقرئ الواقع الإسلامي ، ويكشف عن حالة تشتته ، ومن ثم طرح رؤيته فیما شكل حلاً لمشكلة الركود أو ...
