Figure 11: MRI-LINAC at Sunnybrook Canada (Ref 12) Photo of the project during setup and installation (Ref 15) First patient (Utrecht): The first clinical application was very simple case which is the palliative treatment of spinal bone metastases. This allowed to test the geometrical accuracy of the system on real patients. The vertebra is easily visualized on the integrated megavoltage imaging system and allows for accurate comparison of field co-ordinates with MRI co-ordinates.…

experimented with pieces of iron and discovered that the resistance increases when the current is in the same direction as the magnetic force and decreases when the current is at 90° to the magnetic force [1]. With the growing demands for higher HDD storage density, other forms of MRs with larger variances of resistance due to applied external magnetic fields were needed to be discovered. Two main forms of MRs are: Tunnel Magneto Resistance (TMR) Giant Magneto Resistance (GMR)…

Experiment 1: Scientific Writing and Integrity Procedure 1. A Molecular Explanation of How the Fog is Produced when Dry Ice is placed in Water The main goal of the article written is to try to figure out where the dry ice-in-water-fog (DIWF) was coming from, for there has been discussion if the fog is coming from the water or if it is coming from the dry ice being sublimed. In their terms, they hope “to describe on molecular terms what may be happening in this demonstration” (644). Researchers…

The abiotic factors that affect plant growth and development include topography, soil, and climatic factors. They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetic factor is expressed in the plant. Topography Topography is a nonliving factor that refers to the “lay of the land.” It includes the physical features of the earth such as the land elevation, slope, terrain (flat, rolling, hilly, etc.), mountain…

is one of the simplest and most inexpensive polymers. It is a waxy, chemical inert plastic. It a thermoplastic formed by the addition polymerization of ethylene. There are two types of polyethylene  Low Density polyethylene (LDPE) By using free radical indicator, LDPE is obtained  High Density polyethylene (HDPE) Using ionic catalysts HDPE is obtained • PREPARATION It is obtained by polymerization of ethylene. The gas I first liquefied under high pressure and pumped into a heated pressure…

Following assumption 3, air at the solid-air interface is saturated. The driving force of mass transfer is the difference between the vapor pressure of water vapor at the interface temperature and the partial pressure of water vapor in the air bulk at the bulk temperature. And the variation of moisture content of a single particle can be expressed by equation (4.1): (4.1) Applying shell balance on a spherical particle, the energy balance equation of solid particles can be written as in…

METHODOLOGY: The evaluation of ceramic waste and hypo sludge for replacement of cement material begins with the concrete testing. Concrete contains cement, water, fine aggregate, coarse aggregate and grit With the control concrete, i.e 0%, 5%, 10%, 15% ,20% of the cement is replaced with ceramic waste & hypo sludge the data compared with data from a standard concrete without ceramic waste and HYPOSLUDGE individually. Three cube samples were cast on the mould of size 150 X 150 X 150 mm and…

which the vapour pressure of the liquid equals the environmental pressure that surrounds the liquid. At boiling point, the vapour pressure of the liquid becomes sufficient to overcome atmospheric pressure and lift the liquid to form bubbles inside the bulk of the liquid. For example, at standard atmospheric pressure of 101.325 kPaa, the boiling point of water is 100C…

Hydroxyapatite (HA) has been studied for their excellent performances which are suitable for use in bone defects or regeneration of bone. Hydroxyapatite (HA) has poor mechanical properties which make it limited used in a load bearing area. In this case, sodium alginate (SA) was used to be mixed with hydroxyapatite (HA) by using precipitation method to increase the mechanical and physical properties. The mixing of hydroxyapatite/sodium alginate effectively increases the densification and hardness…

According to 2013 statistics the population of Egypt is a little over 82 million with a steady growth rate of 1.96%, the bulk of its population is rural at about 58%. Population density figures show that the majority of Egyptians live within reasonable distance to the Nile River, there is hundreds of thousands square kilometers that is practically a dead zone because the desert like conditions are too…
