Random Fixed Point Theorem for Weakly Compatible Mappings under Implicit Relation in Cone Random Metric Spaces
In this paper, we establish a unique common random fixed p oint t heorem i n c one r andom m etric spaces for four weakly compatible mappings by using an implicit relation. Some corollaries of this theorem for two and three random weakly compatible mappings are obtained. Some examples are given to support our generalization. Our results presented in ... إقراء المزيد

Common random fixed point results with application to a system of nonlinear integral equations
In this paper, we prove a common random fixed point theorem for two pair of weakly compatible mappings in separable Banach spaces. A corollary of the theorem is obtained and an example is given to verify this corollary. An application is given to obtain the existence and unique solution of system of random nonlinear integral equations. إقراء المزيد

Effect Of Sand Compaction Piles on the Behavior of Expansive Soil Mohammed M. A. Hussei
One of the most common mitigation heave methods for foundation on expansive clay soil is the full or the partial shallow removal of expansive clay soil and replacement with non-expansive soil, usually used sand cushion (SC). Foundation engineers often suggest some arbitrary thickness for sand cushion without considering the depth of the active zone, which is the zone within which ... إقراء المزيد

Cytomegalovirus (CMV) activation in relation to different immunosuppressive induction therapy after renal transplantation
ABSTRACT INTRODUCTION: Cytomegalovirus (CMV) is a common cause of morbidity and mortality among patients receiving chronic maintenance immunosuppression and is often considered the most important infection in renal transplantation. AIM OF THE WORK Our study evaluated the activation of CMV after renal transplantation in relation to different induction therapy comparing with no induction therapy.

Morpho-Anatomical Characteristics of Olive (Olea europaea L.) Trees Leaf as Bio-indicator of Cement Dust Air Pollution in Libya
Comparisons were made between the anatomical and morphological changes in olive tree leaves from a site with relatively clean air (Al-Khadra area), and two sites (al-Khums and Zelatin) near to cement factories in the area east to Tripoli, Libya. Olive tree leaves exhibited marked variations in their morphological and anatomical characteristics, in relations to variations in the site cement dust ... إقراء المزيد

Chapter Title: Side Effects of Insecticides on Natural Enemies and Possibility of Their Integration in Plant Protection Strategies.
Recently, plant protection strategy has recommended, minimizing the use of chemical pesti11 cides. Therefore, studying the side effect of insecticides on the natural enemies is highly re12 quired to exclude the detrimental effects on the natural enemies. Every crop is infested by 13 various pests; some but not all of them may be controlled by biological means using patho14 gens, ... إقراء المزيد

Bio-monitoring of Airborne Dust Particles Pollutants by Morpho-anatomical Reactions of Urban Tree Leaves Under Dry Climate
THIS IS A MORO- ANATOMICAL study where Ficus nitida tree leaves from dust-affected street are compared with those of control from a pollution free site. Under the impact of dust particles, leaf sizes and specific leaf area are significantly smaller and stomatal density differs. Under pollution circumstances, visual symptoms including chlorosis /yellowish and dark spots on the adaxial surface of ... إقراء المزيد
