Scott Eaton The artist of this paper ’s five pieces of work are created and conceptualized by Scott Eaton. He is an artist and designer from the UK and uses traditional art techniques with digital tools. What makes his work so fascinating is his knowledge of anatomy and clean use and mastery of the media. This piece is gorgeous and for it being a digital sculpt‚ you could hardly tell. The texturing is almost like real clay mimicking skin! It is to be acknowledged that this piece was created

In 21st century that we live in‚ communication can be done in many different ways other than conventional speaking right in front of each other. The reason for that is because of the existence of communication technology and the wide interest in this technology from people around the world. Communication technology is improving as we speak and more important sector is depending on it to gain benefits such as business and politics. Communication technology includes telephone‚ radio‚ television

Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely

he v-shaped pattern often occurs in the area where a fire originated‚ so it is possible that the space heater was the fire of origin (tests needs to be run to confirm). The crazed glass (by lab results) indicated that crazing is the result of rapid cooling of hot glass by the application of water. The protected surface shows there was an object on the floor protecting the area‚ What physical evidence did you find at the victim’s home?

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase
