Nitrogen Transformations As Affected By Some Factors at Cultivated Soils In Saudi Arabia
(
Qatar University
, 2000 , Article)
The influence of serial concentration of salts (0.5, 1.0 and 1.5%), application of organic matter (0.5, 1.0 and 1.5% of wheat straw) and varying soil moisture content (50, 70 and 90%) on nitrification in sandy loam soil ...
Recent Advances In Coring And Core Analysis Technology New Technique To Improve Reservoir Evaluation
(
Qatar University
, 2000 , Article)
The main goal of core analysis is to reduce uncertainty in reservoir evaluation by providing data representative of the reservoir at in situ conditions. Basic core analysis measurements are unchanged, but advances in core ...
Geochemistry and Petrogenesis of a Late Proterozoic Volcanic Sequence in the Magal Gebriel Area, South Eastern Desert, Egypt
(
Qatar University
, 2000 , Article)
Metabasalts and meta-andesites together with small amounts of metadacite constitute the Magal Gebriel volanic suite. Restricted amounts of unmetamorphosed rhyolitic rocks are also present. The metavolcanics show a wide ...
Genotoxicity and Embryotoxicity of the Insecticide Primicid in Chick Embryo
(
Qatar University
, 2000 , Article)
Growing chick embryos were treated with primicid to examine the cytogenetic and embryotoxic effects of this insecticide. For the cytogenetic assay, eggs were injected through the air chamber with primicid at a concentration ...
Some Results Concerning Cobb - Voxman's Conjecture
(
Qatar University
, 2000 , Article)
In this paper we shall give some partial results of the following conjecture raised in [3]: Suppose that X is a connected space with a dispersion point p and let f: X —> X be a nonconstant continuous function. Then f(p) = p.
Elliptic surfaces over a genus 1 curve with exactly the pair (I8, IV) of singular fibers
(
Qatar University
, 2000 , Article)
In this paper we classify all minimal elliptic surfaces (TI : E —> C) over a genus 1 curve C, with a section and exactly the pair (Is, IV) of singular fibers.
Elliptic surfaces over a genus 1 curve with the pair (l3, l9) of singular fibers.
(
Qatar University
, 2000 , Article)
In this paper we give a classication of all minimal elliptic surfaces (n : E —> C, g(c) = 1) with a section and exactly the pair (L, L)) of singular fibers.
Application of the Forward Modelling of Sequence Stratigraphy & Diagenesis to The Upper Cretaceous Carbonates Of Western Iraq
(
Qatar University
, 2000 , Article)
Dynamic forward modelling of carbonate diagenesis and sequence stratigraphy relies on the understanding of the different process which provide a high resolution prediction of the geometry of porous and permeable zones ...
Isolation and Characterization of Pollulan Produced by a Local Isolate of Aureobasidium Pullulans
(
Qatar University
, 2000 , Article)
A local isolate of Aureobasidium pullulans was obtained from fig leaves surface. The isolate was identified as A. pullulans on the basis of appearance of polymorphism in the colonies, melanin pigment and pullulan production ...

(
Qatar University
, 2000 , Article)
Along the coastal water of Alexandria, Copepods were collected from four different areas subjected to agricultural/industrial mixed discharge, primary treated sewage flow, industrial effluent and agricultural runoff to ...
