Demersal Fish Resources Around Qatar
(
Qatar University
, 1982 , Article)
The study was based on the data available from Fishery Resources Survey in the Gulf and Gulf of Oman, conducted by F.A.O., between 1975 and 1979 and the samplings of the fish production in Qatar during 1980/81. The survey ...
On Using the One-Exposure Method for Stress Measurements by X-Rays in Technology and Scientific Research
(
Qatar University
, 1982 , Article)
The paper discusses the connection between macroscopic internal stresses and the technological character of technical materials. The basic theoretical relations which are used with X-Ray tensiometry of macroscopic internal ...
The Complexation of Lanthanides by Azo-B-Diketones Stability Constants
(
Qatar University
, 1982 , Article)
The stability constants of the complexes between the trivalent lanthanide series of cations and series of azo-B-diketone ligands are reported. The measurements were conducted at 30°C and zero ionic strength (free KN03), ...
Interpretation of Gravity Anomalies Due to Lens-Shaped Structures
(
Qatar University
, 1982 , Article)
One of the interesting exploration problems in hydrogcology is finding subsurface geological lens-shaped structures. This paper deals with the interpretation of such structures using their gravity anomalies. A master curve ...

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, ...
