Abstract—In this review article, we discuss various technical aspects of image-guided respiration-gated radiation
therapy. We first review some basic concepts related to respiratory gating, including gating window, duty cycle,
residual motion, internal/external gating, amplitud ....etc

Operational and technical aspects of cluster munitions

Mark HIZNAY

Many military establishments believe that cluster munitions increase the efficiency of suppressing, killing or destroying multiple targets within an area and they remain a key military equity. First used in the Second World War and used in 21 states since then, their technology has evolved and they are today perceived as a significant component in the self-defense capability of many states. However, cluster munitions have also demonstrated sev ....etc

2.1. Introduction
2.1.1. The Evolution of Interconnected Systems
Electricity grid interconnections have played a key role in the history of electric power systems. Most
national and regional power systems that exist today began many decades ago as isolated systems, often as
a single generator in a large city. As power systems expanded out from their urban cores, interconnections
among neighboring systems became increasingly common . Groups of utilities began to form power
pools, allowing them to trade electricity and share capacity reserv ....etc

MEDICAL ROBOTS

Ø An Innovative Product of both BME & Mechanical Engg.

Ø Divided into four groups

1.passive 3.active

2.synergistic 4.master-slave

Ø Master-slave is more preferrable

CAS Vs MEDICAL ROBOTS

¢ CAS is powered by surgeon

¢ NO target area is predefined

¢ used for simulating and planning the operative procedure

¢ Less accurate & unsafe

¢ Medical Robots are powered by motorised system

¢ target area should be predefined

¢ programming of instruments is necess ....etc

Reinforced soil is composite material which is formed by the associating of frictional soil and tension resistant elements in the form of sheets, strips, nets or mats of metal, synthetic fabrics or fibre reinforced plastics and arranged in the soil mass in such a way as to reduce or supress the tensile strain which night develop under gravity and boundary forces. It is well known that most granwar soils are strong in compression and shear and weak in tension. The performance of such soils can be improved by introducing reinforcing elements in t ....etc

The adsorption of large molecules, such as proteins and colloids, from solution to solid surfaces is often dominated by steric exclusion of molecules already present on the surface. This talk will review some theoretical approaches to the quantitative description of the adsorption kinetics. In particular, I will describe the Random Sequential Adsorption (RSA) theory for irreversible adsorption and experimental studies that demonstrate its accuracy. I will also present recent work on the reversible binding of macromolecules on heterogeneous surf ....etc
