In the present study, the cluster concept was adopted to find points parallel to the cumulative points of any subset in topology cluster proximity spaces. The takeoff set term was given by the researcher to the set of all points. Also, an opposite definition was found for it, which is the follower set. The relation between them was found and their most important properties were highlighted. Through these two sets, new sets were built that are called, f_σ-set ,f_tσ-set ,t_fσ-set ,bushy set, scant set .
Iraq is changing from the centralized system of governance to the decentralized system, which assumes devolution of more authorities to the local governments of Iraqi provinces and cities. This puts a responsibility on the academics to produce more research work on the best framework for this change, to ensure the best results. The main objective of this research is to suggest a policy for the decentralized transformation in domain of Urban and Regional Planning in Iraq. A suggested program for the transformation is involved in the paper as well, with analysis for the new relationships between different levels of planning authorities depending on democracy. In addition, a description for planning process flows from bottom to top.
This investigation is a study of the length of time where drops can exist at an oil-water interface before coalescence take place with a bulk of the same phase as the drops. Many factors affecting the time of coalescence were studied in is investigation which included: dispersed phase flow rate, continuous phase height, hole size in distributor, density difference between phases, and viscosity ratio of oil/water systems, employing three liquid/liquid systems; kerosene/water, gasoil/water, and hexane/water. Higher value of coalescence time was 8.26 s at 0.7ml/ s flow rate, 30cm height and 7mm diameter of hole for gas oil/water system, and lower value was 0.5s at 0.3ml/s flow rate, 10 cm height and 3mm diameter of hole for hexane
... Show MoreNeonatal mortality is an indicator to assess maternal and neonatal care.1 Iraq has been suffering from wars, economic hardship, terrorism and internal displacement for last 4 decades.2 The impact of such suffering on health was reported.3 However, the impact of terrorism on health infrastructure which in turn manifested in neonatal mortality was neglected. This study carried out to demonstrate the effect of war against terrorism on neonatal mortality in Iraq.
Background: Aflatoxin B1 (AFB1) is a widely distributed mycotoxin in nature. Several investigations have shown its biological effects on different organs and in different animal species. However, the effects of AFB1 on the rat kidney have not been much elucidated histologically.
Objective: This study aims to demonstrate the effects of AFB1 contaminated diet on the rat kidney from
the histological and morphometric aspects.
Method: Twelve mature albino rats were divided equally into a control group fed with usual diet and a treated group which was daily fed with diet contaminated with 20 mg AFB1/kg of body weight for 30 days. Semithin sections from renal cortex were stained with methylene blue and examined by l
Background: Cytokines produced by inflammatory cells play a pivotal role in synovial inflammation and joint destruction in rheumatoid arthritis.
Patients and Methods: The cytokine serum levels were measured by EASIA (Enzyme amplified sensitivity immunoassay) in sera from 50 RA patients, and 40 healthy donors. Cytokine levels were compared in different RA subpopulations (positive or negative rheumatoid factor (RF), long term or recent onset disease, high or low disease activity). In addition, the possible association with other demographic and clinical parameters (gender, age, etc) was also analyzed.
Results: It was demonstrated that IL-2, IL-6 and IFN-δ levels were elevated in serum samples of RA pati
Background: Asthma is an allergic disease characterized by airway obstruction as a result of cellular accumulation due to the liberation of certain mediators. Among those mediators are the cytokines such as IL-5.
Patients & Methods: Interleukin-5 concentration has been estimated in 94 sera samples of Asthmatic patients in comparison with 41 non-asthmatic bronchitis as patient controls in addition to 30 apparent healthy control group using ELISA method.
Results & Conclusions: There is highly significant elevation of IL-5 in the asthmatic cases in comparison with healthy controls (P< 0.001). We conclude that this cytokine may play the major
role in asthmatic attack & it may be a good m
Background: In breast carcinoma, amplification &/or over-expression of HER-2/neu has been associated with a group of unfavorable prognostic factors. The Food & Drug Administration Agency approved Trastuzumab (Herceptin) for the therapy of metastatic breast cancer but only in patients with amplification &/or over-expression of this gene. Because of these advances, evaluation of HER-2/neu status in breast cancer specimens is of vital importance.
Patients and methods: thirty eight females with breast carcinoma were included in this study. All histologic sections were stained routinely with the hematoxylin and eosin stains and
immunohistochemically for HER2/neu. All cancers were graded and subcatego
Background: Chronic Myeloid Leukemia (CML) occurs due to malignant transformation of a pluripotent stem cell. Progression is insidious from chronic to aggressive accelerated or blastic phases. Studies revealed a significant role of the tumor suppressor gene P53 in disease progression.
Objectives: To evaluate the immunohistochemical expression of mutant P53 protein in CML at different clinical phases.
