Get PDFThe global spread of the COVID-19 pandemic, its threat to people’s health and its indirect impacts through the subsequent measures taken by governments to control the disease have led to uncertainty and huge disruption in the way people used to live with a negative impact on mental health and wellbeing. The current study estimate prevalence of the common mental health disorders among a sample of the adult population in the Kurdistan Region during the pandemic. Through an online survey using DASS-21 to measure depression, anxiety, and stress data of 548 adult participants were collected during April 2020 and analyzed. The sample was mainly from Sulaimani (89%), mean age was 37.9 (SD 13.5) and male/female ratio was 1. Prevalence of any severity levels of depression, anxiety, and stress was 45%, 47%, and 18% respectively. In regression analysis, notably female sex was a significant independent factor for higher levels of depression (coefficient 1.89, p<0.05), anxiety (coefficient 2.19, p<0.001), and stress (coefficient 1.52, p<0.05). Postgraduate education and other occupations were also significantly associated with depression (coefficient 3.81, p<0.05; coefficient 2.39, p<0.05 respectively), anxiety (coefficient 2.92, p<0.05; coefficient 4.1, p<0.001 respectively) and stress (coefficient 3.83, p<0.001; coefficient 4.1, p<0.001 respectively). The study indicates high levels of common mental health disorders during the pandemic and calls for public health measures to promote the mental health and resilience of the population
The Implementation of Residential Projects on Sulaimani Master Plan
Get PDFUrban planning is a science that is reflected in the methods of land uses especially housing use, which is one of the most important sector in the city. It is considered the most important human requirement after food and wearer. The master plan is considered as one of the most important urban frame. It contains all the structural plans to control the urban expansion of all service sectors for the land uses in the city. It is planned for present and future status for the cites. The city master plan guarantees the equal distribution of urban land expansion from all sides. It secures the provision and implementation of housing projects to all residents in the city, Because of the economic growth that the city of Sulaimani witnessed after 2003. The city was suffering from a lack of attention to the issue of preparing a master plan. It did not have a master plan except for old studies that were carried out by the federal government. The master plan studies began from 2006 to 2009, then in 2009 it was recognized. Therefore, this subject is very substantial and the problem is that the implementation and site projection of housing was done in unappropriate manner with the stages of the master plan and the absence of evidence to invest in a housing sector. The purpose of this study is to identify a clear vision of housing investment projects, and shed the light on the necessary policies to be considered. Geography information system has been used to indicate the locations of housing projects in the city of Sulaimani. There is conformity with allocated lands for housing in the master plan. Then questions were addressed to specialists and agencies who had worked in housing projects such as the Directorate of Housing, Directorate of Investment, and the municipality. The questionnaire was proven after seeking the assistance of 9 experts to know the extent of the credibility of the questions that were laid down. The research found there are non-planning factors that affect the implementation of housing projects. Absence of laws and administrative errors in the implementation of housing projects playing the main role of having no clear housing implementation vision.

Liquid and Gas Corrected Permeability Correlation for Heterogeneous Carbonate Reservoir Rocks
Get PDFPermeability is considered as an efficient parameter for reservoir modelling and simulation in different types of rocks. The performance of a dynamic model for estimation of reservoir properties based on liquid permeability has been widely established for reservoir rocks. Consequently, the validated module can be applied into another reservoir type with examination of the validity and applicability of the outcomes. In this study the heterogeneous carbonate reservoir rock samples of the Tertiary Baba Formation have been collected to create a new module for estimation of the brine permeability from the corrected gas permeability. In addition, three previously published equations of different reservoir rock types were evaluated using the heterogenous carbonate samples. The porosity and permeability relationships, permeability distribution, pore system and rock microstructures are the dominant factors that influenced on the limitation of these modules for calculating absolute liquid permeability from the klinkenberg-corrected permeability. The most accurate equation throughout the selected samples in this study was the heterogenous module and the lowest quality permeability estimation was derived from the sandstone module
Preventing DNS misuse for Reflection/Amplification attacks with minimal computational overhead on the Internet
Get PDFDNS reflection/amplification attacks are types of Distributed Denial of Service (DDoS) attacks that take advantage of vulnerabilities in the Domain Name System (DNS) and use it as an attacking tool. This type of attack can quickly deplete the resources (i.e. computational and bandwidth) of the targeted system. Many defense mechanisms are proposed to mitigate the impact of this type of attack. However, these defense mechanisms are centralized-based and cannot deal with a distributed-based attack. Also, these defense mechanisms have a single point of deployment which leads to a lack of computational resources to handle an attack with a large magnitude. In this work, we presented a new distributed-based defense mechanism (DDM) to counter reflection/ amplification attacks. While operating, we calculated the CPU counters of the machines that we deployed our defense mechanism with which showed 19.9% computational improvement. On top of that, our defense mechanism showed that it can protect the attack path from exhaustion during reflection/amplification attacks without putting any significant traffic load on the network by eliminating every spoofed request from getting responses

Sero-epidemiological Study of Toxoplasma gondii among Pregnant Women in Akre City
Get PDFRecently has been observed globally that toxoplasmosis disease was caused by Toxoplasma gondii and generally its asymptomatic infection in people except pregnant women. Many previous studies were suggested this pathogen transmits by ingesting of undercooked or raw meat contaminated with the oocytes of this parasite. The study aimed to show the seroreactivity of Toxoplasma gondii antibodies among pregnant women and to evaluate association of studied risk factors with infected cases. ELISA technique used for detection of anti-toxoplasma specific IgG and IgM antibodies. A biography form interview for participant was performed to estimate between the risk factors and toxoplasmosis. The present study was carried out from the beginning of October 2018 to the end of March 2019 and included 90 pregnant women visited Akre general hospital. Out of 90 tested samples, 49 (54.46%) and 4 (4.44%) were positive for IgG and IgM respectively. According to residency factor, pregnant women from villages had higher percentages of IgG (57.14%) and IgM (4.08%) than those lived in the city which were recorded 0% and 48.48%of IgM and IgG respectively. A high percentage of IgG (65.64%) and IgM (7.27%) were found among pregnant women with history of miscarriage. Seropositivity for both IgG (61.90 %) and IgM (9.52%) was higher among pregnant women who had cats compared to those without cat. Seroprevalence of IgM and IgG was 9.67% and 54.83% among population who had undercooked meat, while 1.69% and 59.23% were positive for IgM and IgG respectively, in those well cooked meat meal. Highest positive percentage of IgG (77.77%) was recorded at ages 40-50 years while the lowest rate was (40%) at ages <20 year. Through a seropositive reaction was found that age groups as a possible risk factor by ELISA IgG in which risk increased by rising of age categories. Significant correlation was detected between consumption of undercooked meat and cases positive for IgM. It revealed the association between third trimester and cases with positive IgM. In the conclusion, toxoplasmosis is widespread in the area which requires raising awareness among pregnant women to decrease T. gondii infection and subsequently minimize possibilities of congenital transmission
Ameliorated Impact of Fenugreek Seed Extract on Some Blood Cellular and Biochemical Parameters in Female Albino Rats Exposed to Lead Acetate
Get PDFLead acetate (LA) is considered as the common hazardous compund present in our habitat. It has a several diverse-organ toxicant effect in various healthy issues included diseases of the hepatic, renal, and other body systems. Fenugreek seeds (Trigonella foenum graecum L.) were used in curing medicine and as food supplement since ancient times. After that, their antioxidant and hepatoprotective properties have been studied. Therefore the presented was based on their biological properties of this plant and conducted to examine the protective impact of fenugreek seed extract upon LA toxicity on some blood cellular and biochemical parameters of female albino rats (Rattus norvegicus). Twenty eight female rats were randomly and equally divided into four groups each one contain seven rats as following; first group received basal diet and tap water ad libitum. Second group received basal diet and LA 80 mg/L with water ad libitum. Third group received basal diet contained 2.5% fenugreek seed extract and LA 80 mg/L with water ad libitum. Fourth group received basal diet contained 2.5% fenugreek seed extract with water ad libitum. Rat’s administration was continued daily for two weeks respectively. The administration of rats with LA produced significant reduction in liver weight, food intake, while it increased triglyceride (TG), alkaline phosphatase (ALP), aspartate aminotransferase (AST), uric acid (UA) and creatinie (CR). While supplemented diet with 2.5% Fenugreek seed extract improved body weight, organ weight, lipid peroxidation, TG, ALP, and AST. Our results plead for the profiteering of fenugreek seeds as a dietary supplement, because it showed protective effect of their content in polyphenolic flavonoids, antioxidant and membrane-protective effects, against exposure to the LA compound to protect injurious risk
