A Coupled Random Fixed Point Result With Application in Polish Spaces
In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle. Finally, we apply our contraction to obtain a solution of random nonlinear integral equations and we present a numerical example. Read more

Morpho-Anatomical Characteristics of Olive (Olea europaea L.) Trees Leaf as Bio-indicator of Cement Dust Air Pollution in Libya

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 ... Read more

Chapter Title: Side Effects of Insecticides on Natural Enemies and Possibility of Their Integration in Plant Protection Strategies.

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, ... Read more

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 ... Read more

Safety and efficacy of laparoscopic versus open surgery in management of common bile duct stones. Experience at Sohag university hospital.

Safety and efficacy of laparoscopic versus open surgery in management of common bile duct stones. Experience at Sohag university hospital.
ABSTRACT Background: Management of common bile duct (CBD) stones includes removal of the gallbladder and clearance of the ductal system which can be achieved through different approaches; endoscopic, laparoscopic or surgical. Objective of this study is to assess the safety, efficacy, technical feasibility and surgical outcomes of laparoscopic common bile duct exploration (LCBDE) versus open surgery in the treatment of ...

Common Fixed Point Theorems for Weak Contraction Mapping of Integral Type in Modular Spaces

Common Fixed Point Theorems for Weak Contraction Mapping of Integral Type in Modular Spaces
In this paper, we prove three common fixed point theorems for weak contraction mappings of integral type in modular spaces. In the first theorem we prove a common fixed point of ρ-compatible mappings satisfying a (ϕ - Ψ)-weak contraction. The second theorem is another version of the first theorem. In the third theorem we study a common fixed point of ... Read more

Chapter Title: Biological and Ecological Studies on Land Snails and Their Control. (Accepted for publication in book "Integrated Pest Management and Pest Control"
Mollusca are the second largest phylum of the animal kingdom, forming a major part of the 10 world fauna. The Gastropoda is the only class of molluscs which have successfully invaded 11 land. They are one of the most diverse groups of animals, both in shape and habit. Among 12 gastropods, land snails (subclass: Pulmonata) are one of the most ... Read more

Repellent, Antifeedent and Toxic Effects of Certain Plant Extracts on Cotton Leafworm, Spodoptera littoralis Boisd.
Two plants, i.e. Anthemis melanopodia and Artemesia monosperma were tested against the 4th instars larvae of Spodoptera littoralis (Boisd.) under laboratory conditions. Four crude extracts (Hexane, Chloroform, Ethyl acetate and Ethanol) from each of the two plants used were evaluated by two different technique, i.e. residual films and dipping. Results indicated different percentage of mortality in larval depending on the ... Read more
