Chapter 1 The problem and background of the study Introduction Security is the degree of protection against danger‚ damage‚ loss‚ and criminal activity. Securities as a form of protection are structures and processes that provide or improve security as a condition. It is indeed a great demand and can somehow be a great loss if it is prevented. Security with human responsibility and interference are now at risk of loss because of the technology that certain machines can do. One of this is

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

Have you ever wondered what the inventions of medieval times were like? How people did things such as grinding grain? Well‚ now you will know what it was like. Medieval innovations are fascinating for three reasons. We know about how they did everyday things‚ what science was like‚ and how they affect our scientific progress. Windmills are one type of invention. Windmills were brought to Europe in the 12th century by the crusaders. The sails (the things that turned in the wind) were mounted on a

William Gilbert William Gilbert was also known as William Gilbert. He lived from 24 May 1544 – 30 November 1603. He was an English physician‚ physicist and natural philosopher. He didn’t agree with the traditional way of learning which was to learn completely from books and instead tried investigating and experiments of his own to find out information. He became famous for his experiments with electricity and magnetism which he published books on. William Gilbert first coined the term "electricity"

HEAVY METAL MUSIC WHAT IS HEAVY METAL MUSIC? Heavy metal (often referred to simply as metal) is a genre of rock music that developed in between 1968 and 1974 ‚ largely in the United Kingdom and the United States.With roots inblues-rock and psychedelic rock‚ the bands that created heavy metal developed a thick‚ massive sound‚ characterized by highly amplified distortion‚ extended guitar solos‚ emphatic beats‚ and overall loudness. Heavy metal lyrics and performance styles are generally associated

(corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets on board the vehicle and coils on the ground. The following is a general explanation of the principle of Maglev. fig. 1.1 1.1.1 Magnetic Levitation The "8" figured levitation coils are installed on the sidewalls of the guideway. When the on-board superconducting magnets pass at a high speed about several centimeters below the center of these coils‚ an electric current is induced
