Background: Oral health is important to the quality of life of all individuals. Oral lesions can cause discomfort or pain that interferes with mastication, swallowing, and speech. Oral disease is a health problem that is not only a matter of oral hygiene and local condition, but can also be a precursor to other dangerous and potentially life threatening illnesses. The present study was designed to analyze the main clinicopathological aspects of most common oral lesions in patients who visit the Oral Diagnosis Clinic of the College of Dentistry, University of Sulaimani, Kurdistan region, Iraq. Patients and methods: This prospective study was performed on 3144 patients from July 2009-July 2010. In this study a total of 3144 patients were examined. Of these 1507 (47.93%) were males and 1637 (52.06%) females. The patients' age ranged between 10 to 79 years. An interview was conducted to collect information using a structured questionnaire which was completed by each patient. The lesions that could not be diagnosed by clinical examinations alone were analyzed histopathologically. Results: Among 3144 patients, only 799 patients (25.41%) had oral lesions. Females constituted 49.81% (n=398) and males 50.18 (n=401). The age range of the patients was between 10-79 years with a mean age of 33.75 years. Anatomic changes and developmental anomalies were considered as linea alba (16.68%), Fordyce's granules (12.37%), torus mandibularis (0.66%), torus palatinus (0.55%). Common oral lesions after those considered being anatomic changes and developmental anomalies were fissure tongue (18.23%), cheek biting (12.15%), hairy tongue (6.51%), and recurrent aphthous stomatitis (5.85%) , ankyloglossia (3.75%) , lingual varicosities (2.87%) , frictional (traumatic) keratosis (2.87%) , denture stomatitis (2.54%), recurrent herpes simplex virus infection (2.43%), traumatic ulcer (2.43%), geographic tongue (1.98%), fibroepithelial hyperplasia (1.32%), denture induced fibrous hyperplasia (1.21%) , angular cheilitis (0.99%) , oral lichen planus (0.88%) , median rhomboid glossitis (0.88%) , peripheral giant cell granuloma (0.22%) , and gingival hyperplasia (0.33%) . Conclusion: Routine examinations of oral cavities are valuable in identifying several oral lesions and this will help to establish early diagnosis and treatment and better prognosis particularly early precancerous and other oral lesions.

Phenoxathiin was prepared by the reaction of diphenyl ether with sulfur in the presence of anhydrous aluminum chloride. This work comprised the synthesis of new phenoxathiin derivatives containing heterocyclic moieties. These heterocyclic compounds were synthesized in three groups. The first group was made up of 2-(oxoalken-1-yl) phenoxathiin derivatives (3a-3j) obtained from the reaction of 2-acetylphenoxathiin with different aromatic aldehyde in the presence of sodium hydroxide. The other two groups involved compounds produced from the reaction of (3a-3j) with hydrazine hydrate in acetic acid to get 2-(1-acetyl pyrazolin-3-yl) phenoxathiin derivatives (4a-4j), and phenyl hydrazine in the presence of piperidine to afford 2-(1-phenyl pyrazo

Lignans are natural products widely distributed in the plant kingdom. They are composed of two β-β-linked phenylpropane (shikimate-derived biogenetic subunits). Although the backbone of lignans is composed of phenylpropane units, there is enormous diversity in the structure of lignans leading to different classes of lignans, such as γ-butyrolactone derivatives, eg. Hymatairesinol, bicyclooctadiene derivatives, e.g. pinoresinol, tetrahydrofuran derivatives e.g.lariciresinol, di-arylbutandiol derivatives, e.g. secoisolariciresinol. Introduction of a further carbon –carbon linkage leads to a class of lignans collectively known as cyclolignans such as tetrahydro-naphthalene derivatives, for example podophyllotoxin. Lignans ha

Transport layer is responsible for delivering data to the appropriate application process on the host computers. The two most popular transport layer protocols are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP is considered one of the most important protocols in the Internet. UDP is a minimal message-oriented Transport Layer protocol. In this paper we have compared the performance of TCP and UDP on the wired network. Network Simulator (NS2) has been used for performance Comparison since it is preferred by the networking research community. Constant bit rate (CBR) traffic used for both TCP and UDP protocols.
Abstract : Objectives: The aims of the study are to identify the condition causes respiratory failure in both sex and to find out the relationship between prognosis and mortality rate with condition causes respiratory failure. Methodology : Descriptive study was carried out in Al- Yarmook Hospital in Respiratory care Unit in Baghdad from the 1st of August 2003 to 1st of August 2004, the sample consist of 300 patients (150) males and (150) females, descriptive and inferential statistics procedures were applied to the data analysis Results : The results shows that 24.4% of patients effect by post-operative compl

Iraq depends mainly on Tigris and Euphrates Rivers to provide high percentage of agricultural water use for thousands years. At last years, Iraq is suffering from shortage in water resources due to global climate changes and unfair water politics of the neighboring countries, which affected the future of agriculture plans for irrigation, added to that the lack of developed systems of water management in the irrigation projects and improper allocation of irrigation water, which reduces water use efficiency and lead to losing irrigation water and decreasing in agricultural yield. This study aims at studying the usability of irrigation and leaching scheduling within the irrigating projects and putting a complete annual or seasonal irrigatio

The current study aims to identify the organizational values of kindergarten teachers as well as to identify the difference in the organizational values of kindergarten teachers in term of years of service, to do this; the researcher designed a scale to measure the organizational values. The scale was applied on a sample of (400) kindergarten teachers. The resesults revealed that kindergarten teachers have a high level of organizational values within the classroom. The result of the second objective showed significant differences among the organizational values (political,
