The present investigation revealed cytological variations for six species (Eruca
sativa, Sisymbirium irio, Diplotaxis harra, Erucaria hispanica, Schimpera Arabica
and Brassica tournefortii ) belong to the Brassicaceaefamily.The flower buds were
collected from Al-Habania lake that located in Al-Anbar-Iraq. Using ironacetocarmine
squash technique in anther-smear studies which revealed a
chromosomal anomalies such as Lagging/brddge chromosomes, Micronuclei &
initiated delay of four daughter cells.The frequency of abnormalities ranged (0.04 -
0.77%) which indicated the unstable heredity source of most wildplants. The pollen
grains viability was estimated using acetocarmine stain, viable grains had stained,while sterile grains had not.The biostatic analysis revealed a high significant deference at >0.01 due to the highest numbers of viable pollen grains compared with sterility. Pollen charactersof polar and equatorial view are significantly sufficient for classified characterization of the plant species. An interesting correlationratio of P/E to estimate pollen grain shape, in Brassicaceae polar view was spheroidal three grooves of all species , wide elliptical shape or sub spheroidal in equatorial view, and grains size were medium. The study conclusion that all six species have high productivity of viable pollen grains which confer resistance to environment, therebymeiotic irregularities could be induced unstable genetic resources andsterility.
The research aims at clarifying the role of green human resource management practices in achieving sustainable development. The research problem is that the health sector is less concerned with environmental aspects, specifically green human resource management practices, Which are reflected on sustainable development with their economic, environmental and social dimensions as well as reducing costs, waste minimization and recycling, And the research started from two main hypotheses to explore the correlation and influence between the variables of the research by analyzing the answers of the research sample, which included (136) employees of the Al-Imamein Al-kadhemein medical city, Data and information were collected using quest

This research aims at highlighting the strategic role of human resource development in developing competitive advantage in light of the great challenges and rapid changes witnessed in recent years in the business world. The human element is the main engine of the organization's resources, especially when it possesses the skill quality and cognitive abilities commensurate with the nature of work. Therefore, this research focuses on the importance of human resources development strategy in contemporary organizations and reviews the summary of literature and theoretical foundations related to human resources development, as well as various philosophical concepts related to the competitive advantage and to indicate the important role
... Show MoreThe development of thyroid gland in five developmental stages of common carp, Cyprinus carpio L. The thyroid originates from the pharyngeal floor as a median ventral keel in late embryos having four pairs of arches. It differentiates into profollicular aggergations and true follicles with flattened walls and empty lumina or with lumina filled with cotton waste-like material in three days-old elvers. Secretion of homogeneous eosinophilic colloid with a limited increase in the height of follicular wall is noted in five days-old elvers. In nine days-old individuals the follicles increase in size due to coallescence. The thyroid gland reaches its maximal activity as judged by its histology in one-two months-old individuals. The gland is of t

The potential antimicrobial activity of honey is arise from its physiochemical proprieties such as high osmotic pressure, low pH, in addition to other factors and enzymes that work as antimicrobial agents. All these components and characteristics of honey led to consider it as one of the most efficient, useful and natural antimicrobial agents. From this point of view, recent study aim to evaluate the antibacterial activity of bee honey on some common species of pathogenic bacteria. The study included some of both gram-positive (Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus spp.)

Three isolated bacteria were examined to remove heavy metals from the industrial wastewater of the Diala State Company of Electrical Industries, Diyala-Iraq. The isolated bacteria were identified as Pseudomonas aeruginosa, Escherichia coli and Sulfate Reducing Bacteria (SRB). The three isolates were used as an adsorption factor for different concentrations of Lead and Copper (100, 150, and 200 ppm.), in order to examine the adsorption efficiency of these isolates. In addition, the effect of three factors on heavy metals adsorption were examined; temperature (25, 30, and 37 ?C), pH (3 and 4.5) and contact time (2 and 24 hrs). The results showed that the highest level of lead adsorption was obtained at 37 ?C by E. coli, P, aerugenosa and

Biodiversitas 23: 5239-5246. The biodiversity and water quality of the Diyala River require screening water in terms of biological contamination, because it is the only water source in Diyala City and is used for many purposes. This study aimed to identify a new species record of Cynaophyceae and emphasize the importance of using molecular methods beside classic morphological approaches, particularly in the water-shrinkage-aqua system. Five different sites along Diyala River were selected for Cyanophyceae identification. Morphological examination and 16S rRNA sequen
