This study aims to determine the exposure of dentists to radiation resulting from the use of light therapy units and to assess their risk and impact on dental clinics. This study was conducted in private dental clinics in the city of Erbil in northern Iraq. Surveys were conducted to collect information about light-curing units. The results were analysed using the multi-response logistic regression to determine the factors affecting the radiation values of light-curing units. The results of the study showed that five major variables have a major effect by radiation. This is shown with a value of P ≤ 0.05. Typical treatment times with radiant light, with a typical number of daily restorations, may exceed the risk limits for

Alfred Tennyson (1809- 1892) wrote a compact, action- packed, historical, patriotic, and a pioneering tragedy inspired by the Norman Conquest of England entitled Harold in 1876. It is based on the facts regarding the events leading to the Battle of Hastings in 1066. Tennyson has been, so far, the only man- of- letters to have dramatized this chapter of British history in a tragedy, even though he has never been the only writer to have paid attention to this turning- point in the destiny of his homeland. This tragedy focuses on the personal conflict between Harold Godwinson (1022- 1066) and William Duke of Normandy (1028- 1087), also known as William the Conqueror, or King William I. This drama, thus, is a journey to the pa

Testing the sensitivity of periodontal pathogens requires the selection of an easier and more reliable method to be used with such anaerobic bacteria that need a long period of time for growth. Natural materials are a new era of antibacterial agents to control periodontal infections. The aims of the current study were to test the antibacterial activity of two natural agents, namely olibanum and alum, against three types of red complex periodontal pathogens and compare the application of agar diffusion and microdilution methods for testing the susceptibility.

Authentication is the process of determining whether someone or something is,
in fact, who or what it is declared to be. As the dependence upon computers and
computer networks grows, the need for user authentication has increased. User’s
claimed identity can be verified by one of several methods. One of the most popular
of these methods is represented by (something user know), such as password or
Personal Identification Number (PIN). Biometrics is the science and technology of
authentication by identifying the living individual’s physiological or behavioral
attributes. Keystroke authentication is a new behavioral access control system to
identify legitimate users via their typing behavior. The objective of thi
