ISOLATION AND CHARACTERIZATION OF EXTREMELY HALOPHILIC BACTERIA FROM SADDAM RIVER REGIONS AND THE RULE OF MEMBRANE PROTEINS IN THE RESISTANCE TO HIGH SALINITY
...Show More Authors

This study included isolation and characterization of extremely halophilic bacteria from Al-Massab Al-Aam region in South of Iraq Fifty isolates were identified by using numerical taxonomy 40 strains belonged to the genus Halobacterium which inclucted Hb. halobium Hb. cutirubrum Hb. salinarium Hb. saccharovorum Hb. valismortis and Hb. volcanii. Ten strains belonged to the genus Halococcus which included Hc. morrhuae Hc. saccharolyticus. Growth curves were sensitive mutants determined for wild type and salt Generation time in logarthmic phase was measured and found to be (10.37 2hr 7 0.59) for Hb. salinarium / 18 (6.490 hr 0.24) for Hb. cutirubrum / 32, (6.700 hr + 0.488) for Hb. valismortis / 20, (11.243 hr + 0.96) for Hb. volcanii / 7. (7.509 hr + 0.504) for Hc. saccharolyticus / 42 and for salt sensitive mutant Hь. halobium / HH-S1 and S2 (2.311 hr 0.24) and (2.432 hr 7 0.192) respectively. Bacteriorhodopsin (the only protein in purple membrane) Archacrhodopsin (the only protein in clarate membrane) were isolated from Hb. halobium, Hb. salinarium Hb. cutirubrum Hb. valismortis and the salt sensitive mutant Hb. halobium / HH-P1) was zero However Halorhodopsin was isolated from this mutant, it's molecular weight was 26,000 dalton A protein of unknown function Was isolated from salt sensitive mutant (HH-S1) and found to be 75,000 dalton. It may contribute to the protection of bacteria from lysis in hypotonic environment Three proteins were isolated from wild type and (HH-P1) of Hb. halobium but not from HH-S1 their molecular weight were found to be (44000,78000 and 85000) dalton They may be responsible for the resistance of this bacteria to high salt concentrations

Using of Coating Technique by Inorganic Flame Retardants to Protect Civil and Industrial Foundations from Fires
...Show More Authors

   In the present research the flame retardancy to  buildings and industrial foundations which are manufacturing from advanced polymeric  composite material was increased by coating it with surface layer included flame retardant material.  A(3mm) thick antimony tetroxide was used as a coated layer to retard and prevent the flame spread to the coating surface of polyester resin (SIROPOL 8340-PI) reinforced with hybrid fibers as a woven roving (°45-°0) consist of carbon and kevlar (49) fibers, and exposed it to direct flame generated from gas torch at temperature of (2000ºC), at  different exposed distance (10,15,20mm)and study the rang of resistance for this layer and its ability to protec

The causal relationship between leadership integrity and organizational conflict: An applied research in the State Real Estate Department in the province of Najaf
...Show More Authors

This research aims to know the impact of leadership integrity as explanatory variable including its dimensions (courage, asceticism, justice, rationality, and humanity) on organizational conflict as responding variable. This research depended on the descriptive- constructive approach through the responses of a sample of (79) employees from (Real Estate Office of The State) in Al-Najaf province. The analyzing of the study done by using (Smart PLS) program to calculate (R2, t, p). Many results concluded and one of them, there is significant impact correlation of the leadership integrity on organizational conflict. There are many suggestions have been reached depending on the results reached and one of them is the necessity of de

Zinc (II) removal from simulated wastewater by electro-membrane extraction approach: Adopting an electrolysis cell with a flat sheet supported liquid membrane
...Show More Authors

The aim of this study is to utilize the electromembrane extraction (EME) system as a manner for effective removal of zinc from aqueous solutions. A novel and distinctive electrochemical cell design was adopted consisting of two glass chambers, a supported liquid membrane (SLM) housing a polypropylene flat membrane infused with 1-octanol and a carrier. Two electrodes were used, a graphite as anode and a stainless steel as cathode. A comprehensive examination of several influential factors including the choice of carrier, the applied voltage magnitude, the initial pH of the donor solution, and the initial concentration of zinc was performed, all in a concerted effort to ascertain their respective impacts on the efficiency of zinc elim

From Passive Learning to Critical Thinking
...Show More Authors

Many Iraqi students are reluctant to actively participate in the English
language classroom. This reluctance is attributed to a number of factors, above which
is students' lack of thinking skills necessary to express their points of view. This
eventually results in passive learning, a real problem in English language learning in
Iraq.
A need for educational reforms and innovations seems essential. These involve
developing relevant teaching materials, adopting learner-centered approach,
promoting learner autonomy, and enhancing critical thinking.
This study is hoped to assist teachers of English to initiate change and foster
the expansion of thinking, and adopt various new strategies to increase classroom

The Principle of Prohibiting the Diversion of the Natural Course of International River Waters
...Show More Authors

The research deals with the principle of the prohibition of international waterway diversion in the law of international watercourses. The research reviews individual and collective doctrinal efforts that have touched upon the principle as an internationally wrongful act because of its serious damage and consequences for downstream States. The research addresses the nature of the principle of the prohibition of diversion of international watercourses; its various effects; principles of international law establishing the principle of prohibition of diversion; and its application in State practice and international justice. This principle has been enshrined in most international treaties and judicial decisions. The principle of prohibition
