The system of urban stability in the Kurdistan Region of Iraq
...Show More Authors

The developing countries can be distinguished by spatial disparities and by this a wide gap between urban and rural settlements were produced as well as the appearance of primate cities. The effect of spatial development as a dynamic and continuous process can be perceived in the state of population distribution inside settlements inter and intra regions as well as the hierarchy of urban settlements according to time series. The research proved that the improvement judgment of the structure of the urban system using Gene factor is not accurate because it cannot be accounted for the internal components of the system which make a contrariety between the whole judgment (country) and partial components (Provinces including Sulaimaniyah Province). The population of settlements is distributed in this research for the first time according to interaction axes representing by main roads with Province center to diagnosis the internal spatial immigration towards Sulaimaniyah city as a primate city and delineate the identity of immigrants inside the city. Also for the first time this research makes a quantitative comparison between the urban settlement system of Sulaimaniyah Province at time series using the correlation coefficient according to the logarithmic form of Zipf's ( rank- size) rule. This research delineate the optimal case of number and population size of urban structure in Sulaimaniyah Province using the iteration method in which the minimum population size of urban settlement with respect to ( W.Christaller ) theory is not less than ( 4,000 inhabitants). The amount of primacy is calculated and compared with the optimal situation and also the dispersion was measured using the standard error estimates of regression line model at time series 1977, 1987 and 2002 respectively and compared with the optimal case which has been calculated by the proposed method of one iteration only. This proposed method of optimization which represents a scientific and subjective basis in originating new urban settlements in the future with respect to future population disrribution and a certain policies of housing in the regional plan and deliver the decision makers from objectivity and extemporization judgment which is current in the country till now.

The purpose of the paper is to study the reality of informal housing in Al-Barrakia and the most important problems that it suffers from. The paper also seeks to study the presence or absence of a correlation between urban safety indicators and urban containment indicators as one of the methods of developing and planning cities. This can be achieved through sustainable urban management. The slums are a source of many urban problems that threaten the security and safety of the residents and represent a focus for the concentration of crimes and drugs. The paper seeks to answer the following question: How can urban safety be improved through urban cont

...Show More Authors

The covid-19 global pandemic has influenced the day-to-day lives of people across the world. One consequence of this has been significant distortion to the subjective speed at which people feel like time is passing. To date, temporal distortions during covid-19 have mainly been studied in Europe. The current study therefore sought to explore experiences of the passage of time in Iraq. An online questionnaire was used to explore the passage of time during the day, week and the 11 months since the first period of covid-19 restrictions were imposed in Iraq. The questionnaire also measured affective and demographic factors, and task-load. The results showed that distortions to the passage of time were widespread in Iraq. Participants co

Effects of Two Different Colorant Solutions on the Color Stability of Bleached Enamel in Association with CPP-ACPF: An In Vitro Study
...Show More Authors

Background: One of the drawbacks of vital teeth bleaching is color stability. The aim of the present study was to evaluate the effects of tea and tomato sauce on the color stability of bleached enamel in association with the application of MI Paste Plus (CPP-ACPF). Materials and Methods: Sixty enamel samples were bleached with 10% carbamide peroxide for two weeks then divided into three groups (A, B and C) of 20 samples each. After bleaching, the samples of each group were subdivided into two subgroups (n=10). While subgroups A1, B1 and C1 were kept in distilled water, A2, B2, and C2 were treated with MI Paste Plus. Then, the samples were immersed in different solutions as follow: A1 and A2 in distilled water (control); B1 and B2 in black

Chemical and Biological Study of Iraqi Kurdistan Chamomile Flower (Matricaria recutita L)
...Show More Authors

In this study, the chamomile flowers (Matricaria recutitaL) which grow in Iraqi Kurdistan region during the seasons of (2008) are collected. The percentage of essential oil was determined by using steam distillation and the extraction of flowers performed with petroleum ether (70-80) ºC and methanol 70% using ultrasonic extraction. Total phenolic compounds were determined from methanol extracts by using Folin-Ciocalteu method. The extracts were evaluated by thin layer chromatography, ultraviolet absorption and the biological activities were evaluated through their antibacterial action against two types of bacteria using hole method. The flowers showed a composition of 0.071% ash, 0.4% essential oil, 3.2% non oily compounds, 4% oil, 1.9% mo
