Smoking has been accepted as a risk factor for many chronic diseases, including cardiovascular diseases, respiratory diseases, cancer, ulcers and osteoporosis. Tobacco smoke contains many oxidants and free radicals that can cause damage to lipids, proteins, DNA, carbohydrates and other biomolecules. In vivo, antioxidant nutrients which include vitamin C, selenium (Se), zinc (Zn) and copper (Cu) play a crucial role in defending against oxidant damage. The present study was designed to investigate the influence of cigarette smoking on serum Zn, Cu ,PCV,W.B.Cs., and BMI. Eighty healthy men (40 smokers and 40 non-smokers) from Baghdad, the capital of Iraq, volunteered to participate in this study. Two overnight fasting blood samples were collected from all volunteers. Serum concentrations of trace elements were measured by atomic absorption spectrophotometer. The statistical method of t-test and ANOVA was used to identify differences between the cigarette’s smoker and non-smoker group. Mean body mass index (BMI) was different for the smoker and non-smoker group. Mean of PCV for smoker was significantly (p<0.01) higher than those of non-smokers. The mean count of W.B.Cs., was similar for both smokers and non-smokers The serum zinc levels of smokers were significantly (P<0.05) lower than those of non-smokers. Smokers had significantly no difference in serum copper concentration compared with non-smokers.
An experiment was carried out to study the effects of Time Factor, potassium and Molybdenum on Rhizobium growth. The objective of the experiment, which conducted under laboratory conditions, was to investigate the interaction effects of using three levels of Molybdenum (0, 0.25, 2.50 mg Mo . Kg-1 sterile soil) and four levels of potassium (0, 25, 50, 100 mg K . Kg-1 sterile soil) on the viable counts of Rhizobium growth in the sterile soil after 3, 9, 15 and 21 days of incubation at 28°C. The results indicated that Molybdenum level 2.50 mg Mo . Kg-1 sterile soil and potassium level 50 mg K . Kg-1 sterile soil recorded the biggest significant increase in the viable counts of Rhizobium growth in the sterile soil especially after 15 da

Each bit in the sent information has high priority especially with information such as the address of the receiver. The importance of error detection with each single change is a key issue in data transmission field.
The ordinary single parity detection method can detect odd number of errors efficiently, but fails with even number of errors. Other detection methods such as two-dimensional and checksum showed better results and failed to cope with the increasing number of errors.
Two novel methods were suggested to detect the binary bit change errors when transmitting data in a noisy media.Those methods were: 2D-Checksum me
This research includes the histochemical study of the cestode, Bothriocephalus acheilognathi in order to determine location and concentration of the polymorphism of the calcareous corpuscles in different tissues and organs of the above mentioned cestode. In general, it was noticed abundance polymorphism in calcareous corpuscles, which appeared in the shape of spread clusters, oval structures and floats in location in biological units such as longitudinal muscles, mesenchymal tissue and reproductive organs. The present research indicated various polymorphisms in calcareous corpuscles. Furthermore, the polymorphism in calcareous corpuscles indicates their importance as they ensure survival and continuation of

Show MoreBackground: Inhibin B hormone is one of the indicative parameters in measuring ovarian reserve ,which is important to be evaluated, since it is one of the markers of the female reproductive potential especially in polycystic ovary patients (PCOS) which is a common cause of anovulatory infertility.
Patients and methods: Ninty four infertile polycystic ovaries women, attending the infertility clinic at Baghdad teaching hospital, during the period of October 2005 to December 2006, were compared to 62 control group women who have unexplained infertility. After exact history and examination, inhibin level measurement was done in cycle day 3, the patients are divided according to age into 2 groups (more than 35
Ontology is a system for classifying human knowledge according to its objective characteristics and hierarchical relations through building clusters or that bear common characteristics. In digital environments, it is a mechanism that helps regulate a vast amount of information by achieving a complete link between sub-thematic concepts and their main assets. The purpose of this study is to survey the previously conducted studies that use ontology in organizing digital data on social networking sites, such as the search engines Yahoo, Google, and social networks as Facebook and their findings. Results have shown that all these studies invest ontology for the purpose of organizing digital content data, especially on

Thus, it has become necessary to consider the role of language and its influence on the common beliefs and opinions about rape in the Iraqi society. Thus, taking into consideration the critical role of language and its impact on the perception of human reality and the social development based on people's beliefs and principles of life has become highly indispensable. Therefore. The aim of this article is to address this problem critically from legislation and social norms in NGOs' reports (2015; 2019) with reference to some provisions from the Iraqi Panel Code (1969; 2010). Therefore, the researchers examine the discursive strategies and ideological viewpoints in t

This study analyzes how to make use of the resources in the marshlands of Iraq and how to utilize them, especially after the water returns to these areas and they are revitalized. We take an example of AL- Saheen Marsh and plan an ideal tourist resort there. This example can further expand to include other parts of the marshlands. The resort will utilize the local environment and tourist characteristics as it will have a feel and architectural resemblance to the houses and buildings that are currently built there. In addition the transportation methods will be the same as those used by the locals. Yet the resort will still posses all the facilities required by a modern tourist resort that includes all the services that will make
