A Note on Norland Summability of Fourier Series
( Qatar University , 1982 , Article)In this paper we consider point-wise summability in the Norlund sense of Fourier series by assuming H(n) . F(n) = o (Pn) as n--+ oo, where (H(x) = d.x g(t) dt, g(t) is continuous, non-increasing, H(x) is slowly varying, ... -
A Note On Pre-J-Group Rings
( Qatar University , 1991 , Article)Given an associative ring R satisfying a°'b = Ba" for any pair a and b of its elements, is being a positive integer, and a group G satisfying x""' = y"~1, we give a sufficient and necessary condition on the group ring GR ... -
A Note On Semi Generalized Closed Sets

Noun quantification in English and modern standard Arabic: a descriptive morphological comparison
( Qatar University , 1997 , Article)This paper examines quantifiers from a morphological point of view. It will focus on number in nouns, partitive constructions, collective nouns, numeral quantifiers, and non-numeral quantifiers in both English and Modern ... -
A novel push-pull machine for testing High cycle fatigue
( Qatar University , 1990 , Article)A novel machine designed and constructed to exert cyclic axial load for fatigue testing is herein reported. The main features of the test rig constitute the sinusoidal form of load wave and the stress - controlled, system ... -

Numerical Abundance And Species Diversity Of Surface Zooplankton In The Coastal Waters Of United Arab Emirates On The Arabian Gulf A Preliminary Study
( Qatar University , 1999 , Article)Surface zooplankton of the coastal waters of the United Arab Emirates was studied bimonthly during the period September 1997 to July 1998. Species diversity, numerical abundance and seasonal dynamics were analyzed , at six ... -
A Numerical Solution For The Bending Of A Plate Using The Boundary Element Method
( Qatar University , 1992 , Article)In this paper the numercial solution for the bending of a plate is considered. The method used is called the Boundary Element Method (BEM). The BEM is a numerical method based on the boundary integral equation formulation ... -
Numerical Study Of Magneto-Fluid-Mechanics Forced Convection Pipe Flow
( Qatar University , 1994 , Article)The problem of fully developed, laminar, steady, forced convection heat transfer in an electrically conducting fluid flowing in an electrically insulated, horizontal, circular pipe (whose wall is subjected to a uniform ... -
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 ... -
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 ... -
