Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

STATEMENT OF THE PROBLEM Main Problem: How can the ionization chamber detect if the environment is surrounded or has Radon? Sub- Problems: What are the primary sources of radon gas? What elements are found when radon decays? How can this gas cause different kinds of diseases? OBJECTIVE: Build a simple ionization chamber that is capable of detecting fairly low levels of radiation BACKGROUND OF THE STUDY Radon is a cancer-causing gas. It comes from the natural breakdown of uranium in soil

ABSTRACT In the present world of the human mind always need information of interest to control systems of his/her choice. In the age of electronic systems it is important to control and acquire information from everywhere. Although many methods to remotely control systems have been devised‚ the methods have the problems. Hence the need for special devices and software came to control the system. This suggests a method for control using the DTMF tone generated when the user pushes mobile phone

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314
