Assignment 1 Play activity This assignment had been done with a group of 4 children with ages between 3 and 4½. Planning: In order to do the play activity I had to observe the children for two days. I wanted to know what are they more interested in and what they would like more. After the observation stage‚ I wanted to make sure that the play activity I had in mind‚ suited their age and stage of development. I also made sure that the activity is safe and that it included the PILES

Advantages 8 References 9 Magnetic Abrasive Finishing (MAF) Process Harry P. Coats first patented MAF in 1938. Although US originate this idea‚ most of later period development is done by USSR + Bulgaria. Japanese explore the technology for polishing purpose. Other countries in this field are: India‚ CIS‚ England‚ France‚ and Germany etc. Process details: • In MAP‚ w/p is kept between the two magnets & the air gap in-between the w/p & the magnet is filled with Magnetic Abrasive Particles (MAPs)

wavelengths) you get what is commonly known as a visible light wave. Light is very common in the Universe. Light is so common that everything on Earth has evolved to us life to its advantage to survive. If you were to take a prism and put light to it‚ it can slow light down by a fraction by revealing its much more colourful side. This is commonly known as the visible light spectrum. On one end of the spectrum you have red and on the other you have Violet. Red is red because its wavelengths are larger and

The Emotional effects of war on soldiers. Manali Oak describes war as "a manifestation of death and destruction". “The Hurt Locker” aptly captures the above definition of war. It is one of the best movie releases of the year 2009 and by the trends; it continues generating a lot of hype for quite sometime (Manali O). Personally‚ I couldn’t get enough of watching the scenes over and over again‚ as I kept asking myself‚ "Is this exactly what is happening in Iraq? Are these soldiers really

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

according to the magnetic source‚ the magnetic separator can be divided to permanent magnetic separator and electromagnetic separator. 2‚ according to the strength of magnetic field‚ it can be divided into: (1) Weak magnetic separator‚ the surface magnetic strength HO=72-136 KA/m‚ magnetic force HgradH= (2.5-5.0) 1011 A/m. (2) Middle magnetic separator‚ the surface magnetic strength HO=160-480 KA/m; (3) Strong magnetic separator‚ the surface magnetic strength HO=480-1600 KA/m‚ magnetic force HgradH=
