and treatment of the orbital fracture which my is my interest about maxillofacial surgery .In this thesis I would like to concern more bout the treatment of the orbital fractures. Fractures of the orbit are common and challenging to manage.Most orbital fractures occure in males in their second decade of life.In adults motor vehicle accidents and sports are common mechanisms of injury . However, In pediatric pationts falls and sports related injuries are more common. Orbital fractures are often broadly

Introduction Orbital cellulitis is frequently used to represent a broad spectrum of orbital infections. In 1970 Chandler created a classification system of the various stages of infection, based on severity, to separate this spectrum in five groups: I) pre-septal cellulitis (inflammatory edema); II) Orbital Cellulitis; III) Orbital Subperiosteal Abscess; IV) Orbital Abscess; V) Cavernous Sinus Thrombosis.1,2 The incidence of Orbital Abscess in pediatric population is 15% of the orbital infections,

As mentioned in the heading,the intention of this thesis is about diagnosis and treatment of the orbital fracture which my is my interest about maxillofacial surgery .In this thesis I would like to concern more bout the treatment of the orbital fractures. Orbital fractures have a higher occurrence in males especially in their second decade of life. Orbitial fractures are as a result of trauma, and is best chacterised according to age. In adults motor vehicle accidents and sports are common mechanisms

laying out the equations describing an orbital spaceflight in which the landing position of the spacecraft is specified. It was the first time a woman in the Flight Research Division had received credit as an author of a research report. In 1962 NASA prepared themselves for the orbital mission. Katherine would have a moment to remember. She would be doing something that would make her well known for. The work that was required Katherine was well for. Orbital flight had required the construction of

Introduction  Activity 3.1 Look at the pictures above and answer the following questions. Record your answers and discuss them in your groups. 1) Observe carefully pictures A, B and C and suggest the similarity between them. 2) What can you say about the chloride and sodium ions in the pictures above? 3) What holds the chloride

Electrons inhabit an orbital. Orbitals can be visualized as clouds around the nucleus. Orbitals do not mean that electrons travel in orbits, because due to the Heisenberg Uncertainty Principle, it is impossible to define with absolute precision, at the same time, both the position and the momentum of an electron. Each orbital may only contain 2 electrons. The s orbital (orbital closest to the nucleus) may only contain 2 electrons and then is ordered from p orbital (three sets may contain 6 electrons

by assault or impact from solid objects, often causes internal orbita fractures. In 1957, Smith and Regan described the term “orbital blow-out fracture” from their observation that blunt eyeball trauma due to a tennis ball or a fist increased intraorbital pressure without disruption of soft tissue integrity or causing a fracture line in orbital rims but could cause orbital floor fractures (1). Such fractures have been categorized as “pure blow-out fractures” in which only the orbita floor is affected

The Space Shuttle was a partially reusable launch system and orbital spacecraft operated by the U.S. National Aeronautics and Space Administration (NASA) for human spaceflight missions. The system combined rocket launch, orbital spacecraft, and re-entry spaceplane with modular add-ons. The first of four orbital test flights occurred in 1981 leading to operational flights beginning in 1982. It was used on a total of 135 missions from 1981 to 2011 all launched from the Kennedy Space Center, Florida

increase in entropy the the initial temperature. Orbital energies in multi-electron atoms are mere difficult to calculate due to the additional Select the correct answers from the following multiple choice questions. Each .y...~4o‘m: correct answer carries 1.0 mark and for each wrong answer 0.25 marks will be deducted. Probability density for 1s orbital of hydrogen atom is maximum at (a) r 1 do (in) r = 0 (c) r = 2:10 (d) r = 0.5 no The RDF for 1s orbital of hydrogen atom has maximum value at (a) r =

normal orbital cortex activity. However, results showed that he had the same low orbital cortex activity as a serial killer. The orbital cortex is the area that is believed to be involved with ethical behavior, moral decision-making, and impulse control. According to Fallon, people with low orbital cortex activity are either free-willing types, or sociopaths. The orbital cortex helps control the amygdala area of the brain, involved with aggression and hunger. Low activity of the orbital cortex

imposed by the galaxy. It is hypothesised that the orbital period of the stars will increase as the radius of the star from the galactic centre is increased. This is predicted as the star will have a larger orbital path than that of a star which is closer to the galactic centre, which means that it should orbit the galactic centre at a much slower rate. The rotation curve of disc galaxies is the plot of the magnitude of visible stars or gas in galaxy orbital velocities against their radial distance from

collisions between satellites. Until recently, it has been standard practice to put a satellite into orbit and leave it there. However, the number of satellites has grown quickly, and as a result, the amount of orbital debris is growing rapidly. Because this debris is travelling at orbital speeds (7-8 km/s), it poses a significant threat to the space shuttle, the International Space Station, and the many satellites in Earth orbit. This problem can only be solved globally.Travelling at up to 28,000

Anatomy of the Lacrimal System Study of the lacrimal system is a synthesis of two disciplines, ophthalmology and otorhinolaryngology, which work closely together in the treatment of nasolacrimal disorders. A thorough understanding of the anatomy of the lacrimal system will help the surgeon to reach correct diagnosis, facilitate the chance of a successful surgical outcome and makes the surgeon confident of his skills. The lacrimal drainage system anatomy can be discussed under following components:

to determine how the brain of a serial killer is different from other brains - He scanned his own brain and compared it to brain scans of psychopaths - He also compared his brain to his son's, which showed normal orbital cortex activity - Results showed that he had the same low orbital cortex activity as a serial

earth and follow its gravitational force as it goes from one side to the other. So using this we can see that for any given altitude there is a specific orbital velocity required for any object to achieve a stable circular orbit. Applying Newton’s law of universal gravitation to the orbital motion of a satellite allows us to find a formula for orbital velocity. This can be shown as: Fg=G mems/r^2 where me is the mass of the Earth (5.97 ×〖10〗^24 kg), ms is the mass of the satellite (kg), r is the radius

summarized: ●Unilateral headache ●Granulomatous inflammation of the cavernous sinus, superior orbital fissure or orbit, demonstrated by MRI or biopsy ●Paresis of one or more of the ipsilateral third, fourth, and/or sixth cranial nerves ●Evidence of causation demonstrated by both: •Headache has preceded oculomotor paresis by <2 weeks or developed with

charge felt by more than one electron in an orbital is not the same. This is due to electrons have the same charges, thus repel each other and shield the nucleus. Helium has two electrons; hence electrons repel each other and shield the nucleus. Additionally, the 1s orbital is close to the nucleus as compared to 3s orbital. Therefore, when an electron is placed in the 3s orbital, averagely it would be farther from the nucleus than electrons in a 1s orbital. When 3s and 3p radial distribution functions

of 4 cases which presented as ocular adnexal masses and a view on clinicopathological details. Key-words: B cell NHL, Introduction Majority of the orbital lymphomas are B cell non-Hodgkin's lymphomas and tend to present in the 6th and 7thdecades. Presentation before the age of 20 is rare. In children, orbital leukemic infiltrates are much more common than lymphoma. Most subtypes of lymphoma have a female-to-male risk of 1.5:1. Lymphomas of the eye are usually located superiorly
