Organ Motion: RT of thoracic and abdomino-pelvic targets poses difficulties of precise target localisation and patient positioning. There is considerable variation in patient position and organ location during planning and treatment. This could be due to difficulties in precise positioning‚ and immobilisation‚ patient movement and organ motion. Consequently there is a chance of deviation in the dose absorbed from the actual planned dose to be delivered. Accurate understanding of the details of organ

top of the cup‚ the shorter the distance of the cup moved and it included all of the three Newton’s laws. My hypothesis actually turned out to be accurate. It’s really fascinating that how only 1 experiment can prove all of Newton’s three laws of motion just like that. When the marble was getting released from the ramp I observed it hitting the cup and surprisingly the cup didn’t fall off or changed directions it went in a straight path. For 1 penny we got the longest distance such as 4cm for trail

RESEARCH IN MOTION MANAGING EXPLOSIVE GROWTH In the January of 2008‚ Research in Motion (RIM) is standing at the strategic juncture where important decisions need to be taken regarding global expansions. The biggest strategic issue it faces is to carry over yesteryears’ growth to next level through sustainable innovation at global level. Although its R&D expenditure has grown 6 times in the last four years‚ the ratio of R&D expenditure to sales has been halved. This ratio shows RIM is

How does the mass of a ball affect the distance it will travel ? Exploring Newtons 2nd Law of motion. Background Research How does changing the mass of an object effect how far it will travel ? This question can be answered by Newtons 2nd law of motion; Force equals mass multiplied acceleration (F= ma). This law states that a force on an object will cause it to accelerate in the direction of the force. The greater the force exerted on the object‚ the greater the acceleration. But how does

Research in Motion: Managing Explosive Growth Research in Motion was founded in 1984 by Mike Lazaridis and was a world leader in the mobile communications market and manufactures products such as the BlackBerry. Mobile wireless communication involves the transmission of signals using radio fequencies between wireless networks and mobile access devices. One of the main economic characteristics of the industry is the high growth potential that exists. This growth potential is exemplified by RIM expecting

Using a sample of 100 motion pictures from 2005 and numerical methods of descriptive statistics‚ including measures of location‚ variability‚ distribution shape and the detection of outliers‚ the motion picture industry can be analyzed more specifically in order to learn how these variables play a part in the success of a motion picture. The main concern of management in this case would be with regard to revenue‚ profit‚ and

Kalia Townsend Earth Science A2 5/28/14 ECCENTRICITY LAB REPORT Keplar’s First Law of Planetary Motion: The orbit of every planet is an ellipse with the sun at one of the foci. The purpose of this lab is to demonstrate Keplar’s First Law of Planetary Motion by calculating the eccentricity of ellipses. The 3 main words that were important in this lab exercise was eccentricity‚ ellipse‚ and foci. Eccentricity means the degree of ovalness of an ellipse or how far an ellipse is from being a circle.

Carefully watch the objects vertical position as a function of time. Repeat your toss enough times that you are sure that you understand the motion of the object. In order to answer the following questions‚ imagine

Both skaters accelerates away from each other The flying motion of birds A bird flies by use of its wings. The wings of a bird push air downwards. Since forces result from mutual interactions‚ the air must also be pushing the bird upwards. The size of the force on the air equals the size of the force on the bird;

ENERGY CONSIDERATIONS IN PLANETARY AND SATELLITE MOTION Consider a body of mass m moving with a speed v in the vicinity of a massive body of mass M‚ where M >> m. The system might be a planet moving around the Sun‚ a satellite in orbit around the Earth‚ or a comet making a one-time flyby of the Sun. If we assume that the body of mass M is at rest in an inertial reference frame‚ then the total mechanical energy E of the two-body system when the bodies are separated by a distance r is the sum
