A simplified method for calculating saturated liquid densities
(
Elsevier B.V.
, 2004 , Article)
A simplification for the Nasrifar–Moshfeghian (NM) liquid density correlation has been developed. A replacement for the Mathias and Copeman temperature-dependent term with the original Soave–Redlich–Kwong equation of state ...
The mathematical theory of finite and infinite dimensional topological spaces and its relevance to quantum gravity
(
Elsevier Ltd
, 2009 , Article)
The present work gives first a review of the mathematical theory of finite and infinite dimensional topological spaces. Subsequently we connect the discussion with E-infinity theory and the theory of partially ordered sets. ...
Constituents of Plants Growing in Qatar XXXIII Proximate composition of thirty four food and feed plants growing in Qatar
(2003 , Article)
34 wild species within 32 genera belonging to 14 families from the flora of Qatar were analyzed for their moisture, lipids, carbohydrate, protein, crude fiber and ash content
Geology and petrology of the Hormuz dolomite, Infra-Cambrian: Implications for the formation of the salt-cored Halul and Shraouh islands, Offshore, State of Qatar
(
Elsevier Ltd
, 2008 , Article)
Geological investigations of the Halul and the Shraouh islands, offshore Qatar, indicate that most of their calcareous rocks, which display abundant stromatolitic bedding, belong to the Infra-Cambrian Hormuz Series. ...
Standard numerical schemes for coupled parallel flow over porous layers
(
Elsevier
, 2007 , Article)
In this work, we develop finite difference schemes of various orders of accuracy that are suitable for the simulation of flow through and over porous layers. The flow through the porous layer is assumed to be governed by ...
Adaptive and Predictive Control of Liquid-Liquid Extractors Using Neural-Based Instantaneous Linearization Technique
(
WILEY-VCH Verlag GmbH & Co.
, 2006 , Article)
Nonlinearity of the extraction process is addressed via the application of instantaneous linearization to control the extract and raffinate concentrations. Two feed-forward neural networks with delayed inputs and outputs ...
موقف أهل السنة من الرواية عن أهل الأهواء و البدع : دراسة نظرية تطبيقية
(
جامعة القاهرة - كلية دار العلوم
, 2009 , Article)
إن أئمة الجرح والتعديل جعلوا نقد أهل البدع وتجريحهم هدفهم الأول حتى يميزوا بين المقبول والمردود من الأحاديث؛ فمدار هذا البحث على رواية المبتدع لأن الفرق الإسلامية الأخرى تعد من المبتدعة في نظر أهل السنة. في حين نجد أن صحيحي ...
Analytical approach to the Darcy–Lapwood–Brinkman equation
(
Elsevier
, 2007 , Article)
Three exact solutions are obtained for flow through porous media, as governed by the Darcy–Lapwood–Brinkman model, for a given vorticity distribution. The resulting flow fields are identified as reversing flows; stagnation ...
Generalized dynamic spectrum access: An order statistics design perspective
(
Elsevier GmbH
, 2008 , Article)
A new adaptive multiple access scheme based on the theory of order statistics is introduced. The proposed algorithm employs a semi-random allocation mechanism that limits subchannel selection to the highest-gain subchannels. ...
Present day inbreeding does not forbid the forensic utility of commonly explored STR loci: A case study of native Qataris
(
Elsevier Ireland Ltd.
, 2008 , Article)
Allele frequency distribution of 15 short tandem repeat (STR) loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA) was studied in a sample of 120 ...
