The Roles of Landscape Features in Re-Making Sense of Place in Mosul City Centre
Get PDFDue to the unfit development of street characteristics, and negligence of maintenance, street loss what is precious and its sense, here the people’s feelings and perception of the streets have been negatively affected. This paper highlights landscape features as physical characteristics of streets including soft landscape (trees) and hard landscape (street furniture). This is to identify the roles of these two types of landscape features in securing sense of place. Nineveh Street in Mosul City Center, Iraq is selected as a case study. Mixed methods were selected for this research, quantitative technique by using 330 questionnaire survey, and qualitative technique by using 30 semi-structured interviews and direct observation. The study concludes that landscape features of streets contribute to create sense of safety and comfort that in turns give sense of place. The lack of the role of landscape features in providing safety and comfort has a negative effect on reducing the influence of sense of place in the street
Investigating the role of urban spaces in reduction of digital divide between citizens
Get PDFThe information and communication technologies and their ever expanding and development have transformed all the basic concepts of human life, including the collective life of humans in urban spaces. Now these technologies have caused gradual and sometimes sudden changes in the concepts of space, so that, along with urban spaces, we are witnessing the creation of virtual environments with a wide variety of inclusive activities. This phenomenon led to the formation of virtual communities with a metropolitan state and the virtual universe formation in parallel with the real world. One of the implications of dual spatial and globalization for life of human beings is the creation of a crisis called the digital divide, which is associated with individualism, the reduction of social interactions levels, reducing collective life in the city's social spaces. The present study is carried out aimed to explain the role and capabilities of urban spaces on reducing the individuality of the crisis and promoting interactive levels and social integration. For this purpose, in the research process, three methods of environmental mapping, observation of behavior and interview with users in the Bam-e Tehran Recreational Complex have been used. The results showed that cyberspace is not considered as a substitute for physical space and serves as a complement to complete the social functions of urban spaces. Therefore, the creation of smart environments in this urban space and the creation of a hybrid space of physical and cyberspace, called the cyber park, will lead to an ever-increasing active presence of citizens and the promotion of levels of social interaction and ultimately reduce the digital divide among citizens
Effect of Testosterone on Lead Acetate Toxicity in Male Albino Rats
Get PDFThe toxicity of lead acetate (L. A.) concerned to public health disruptor due to its persistence in the environment and it has the adverse influence on the human and animal health as well. It causes physiological,biochemical, and neurological dysfunctions in humans. Histologically it has a negative effect on the liver which is considered one of the major target organs where acts as detoxification machine by elimination the toxic substance from the blood in rich with it. As well as it affects kidneys that are the two of the most filtering organs. Therefore the present study was aimed to investigate the histopathological effect of L.A. on liver and kidney tissues in male rats. Twenty male rats involved in the study were equally and randomly divided into two groups each of them involved 10 animals. Group I (castrated rats) and Group II (control) each group received 80mg/L of lead acetate dissolved in one liter distilled water by drinking for 15 days. Histological sections showed some alterations including abnormal architecture, cell degeneration, nuclear degeneration, hyperchromatic hepatocytes, immune cells, degeneration in tubules, dilation in sinusoids, dilation in central vein of liver increased bowman's space glomerular atrophy degeneration of tubular cells in liver and kidney tissues of rats in castrated rats from control group. But the size of degenerated tissue was more severe in castrated male rats. It was concluded that the castration process could produce a hypogonadism and decreased testosterone which owns many receptors in kidney and liver may produce adverse influence with L.A. administration

Bacteriological Profile and Antibacterial Sensitivity Patterns of Isolates among Burn Patients in Sulaimani
Get PDFNosocomial infections have increasingly been implicated in transferring fatal septic complications in burn patients. Also multidrug resistant profiles of microorganisms are being increasingly found in burn wounds which are very much alarming due to the limited number effective antibacterial drugs. Retrospective data were collected from burn patients at Sulaimani Burn and Plastic Surgery Hospital between January 2013 and December 2015. Culture& sensitivity tests were performed using wound surface swabs and tissue culture over the three year period. Their results were collected in a predesigned digital form. Statistical analysis was done and results plotted. Out of 500 burn positive swabs samples were previously taken from hospitalized patients, the commonest bacterial isolate were gram-positive bacterial infection; Methicillin-Resistant Staphylococcus Aureus (MRSA) 215(43%) followed by gram-negative bacterial infection; Acinetobacter baumannii and Pseudomonas aeruginosa 95(19%) and 85 (17%). Vancomycin has no any resistant rate for all gram-positive bacteria followed, but Teicoplanin is the second best drug especially, for MRSA 8.4%. Imipenem and Meropenem are antibiotics with no or less resistant rates for most of gram negative bacteria. Resistance to antibiotics is rapidly increasing in our community and burn wounds are frequently infected by these multidrug resistant organisms. Careful antibiotic selection and effective control of these strains can be translated into lower morbidity and mortality for these patients
