Observations on some hydrochemical aspects of the United Arab Emirates waters along the Arabian Gulf and the Gulf of Oman.
( Qatar University , 1997 , Article)Surface and bottom water samples were collected from the United Arab Emirates waters along the Arabian Gulf and the Gulf of Oman during the period from October 1993 to September 1995. Samples were analyzed for temperature ... -
Occurence of Phytoplankton in Stomach Content and Its Selectivity by Nile Tilapia (Oreochromis niloticus L.) Cultured in Fertilized Earthen Ponds
( Qatar University , 2003 , Article)Nile tilapia (Oreochromis niloticus L.) was cultured in earthen ponds receiving 0, 20, 40, 60 and 100 kg/feddan/month of inorganic fertilizer (20:20:5 N:P:K). The obtained results showed that the composition percentage of ... -
Ocean Acidification and Carbonate System Geochemistry in the Arabian Gulf
( Qatar University Press , 2020 , Poster)Alkalinity (Alk) and (Dissolved Inorganic Carbon) DIC were measured on high resolution seawater samples, collected on November 2018 and May 2019 at seven stations in the Exclusive Economic Zone (EEZ) of Qatar. Calculated ... -
Off - Grid Power Supply Solution for Portable Cabins using Solar PV System for Qatar
( Qatar University Press , 2021 , Poster)In this project, a new system for power supply for remote areas has been proposed. In the proposed system, solar PV based system with battery storage for stand-along application has been discussed. In addition, the use of ... -
Offsite Construction in the UK: Economic and Environmental Benefits
( Qatar University Press , 2023 , Conference Paper)In contrast to traditional piece meal onsite construction, offsite construction comprises the planning, designing, production, transporting, and assembly of building elements for speedy site assembly to a higher degree of ... -
Oil Spill Index (OSI) to Sentinel-2 satellite data: QU in International Contribution
( Qatar University Press , 2021 , Poster)An Oil Spill Index (OSI = (B3+B4)/B2) was developed and applied to Sentinel-2 optical satellite data of the European Space Agency (ESA) to map marine oil spills using spectral absorption characters of spectral bands of the ... -
Omega-3 fatty acid-rich fish oil supplementation prevents rosiglitazone-induced osteopenia in aging mice
( Qatar University Press , 2021 , Poster)Rosiglitazone is an effective insulin-sensitizer, however, associated with bone loss mainly due to increased bone resorption, and bone marrow adiposity, and decreased bone formation. We investigated the effect of the ... -
On 2n+L-Vertex-Free Graphs
( Qatar University , 1983 , Article)We shall introduce the concepts of pseudoadjacent, pseudocoatraction and pseudoho-momorphism. We shall show, with the help of these concepts, in theorem 2 that every quadrilateral graph V (which is a 4-vertexgraph) has ... -
On A Kp Class Of Partial Differential Equations Conservation Laws And Solitary Wave Solutions
( Qatar University , 1996 , Article)It is shown that a KP class of partial differential equations possesses an infinite number of conservation laws. In addition, exact and explicit solitary wave solutions are constructed for the KP class of equations, which ... -
On a mixed boundary value problem for elliptic equations
( Qatar University , 1988 , Article)In this work, a general form of linear and quasilinear elliptic equations is considered. In the presence of boundary singularities, some estimations for the error, according to the net method, are obtained. -
On A New Haemogregarine Of Varanus Griseus From Egypt
( Qatar University , 1996 , Article)Ten monitors, Varanus griseus collected from various localities in Egypt were examined for protozoan blood parasites. A new species of the genus Haemogregarina senso lato is reported from six of these monitors. Blood forms ... -
On A Relation Between Two Absolute Summability Methods
( Qatar University , 1997 , Article)In this paper we prove a theorem concerning a relation between the summability methods |R,pn,qnlJt and |R,un|fc , k > 1 , which generalizes a result of Bor [2]. -
On an inverse scattering problem with a discontinuous coefficient On the whole line
( Qatar University , 1994 , Article)This paper is devoted to study the inverse scattering problem of a generalized Sturm-Liouville equation on the whole line.The solutions of the considered problem and their asymptotic behaviour are presented.The expansion ... -
On Dirichlet Problem With Singular Integral Boundary Condition
( Qatar University , 1983 , Article)In this paper a Dirichlet problem, with singular integral condition, is studied. It is shown that such problem can be reduced to a regular equation which allows us to construct the solution. -
On estimates of the rate of convergence In the global limit theorems for Homogeneous markov chains
( Qatar University , 1997 , Article)In this paper some estimates are obtained for the remainder term in the limit theorems for the weighted sum of random variables forming a homogeneous Markov chain with arbitrary set of possible states . The achieved results ... -
