CHAPTER 1 INTRODUCTION 1.1 General The micro-emulsion inks have a wide range of applications in industry. The ink used earlier for printing purposes contributes to pollution in environment. The pollution is by means of emission of volatile organic compounds (VOCs) which are present in the form of an aliphatic solvent. Emission of VOCs from these solvents and their discharge in waste streams are quantifiable. For example a typical medium size cold – set web plant uses 40,000 kg per year

This is due to the small size of the Artemia nauplii, and it would have been easier to observe their movement in smaller petri dishes. The coloured filters used to create different wavelengths of light may have caused the light intensity from the torch to have decreased, so the intensity of light may have varied for each wavelength of light. As different torches were used

are the steps for immobilizing the flies. Hold the vial containing the flies at an angle and place it in a refrigerator for several minutes. When the flies are immobilized, place them into a small plastic Petri dish. 3. Use the dissecting microscope to view the flies. Make sure to top the petri dish on when viewing the flies. 4. You can easily distinguish male flies from females by looking for the following characteristics: males are usually smaller than the females, males have dark blunt abdomens

These materials are: seeds of specific phenotypes, seed-collecting pan, small envelopes, several wicks, opaque tape, Styrofoam quads, fluorescent light bank, water reservoir, water, water dropper, potting soil mix, fertilized pellets watering tray, petri dish w/ filter paper, and a paint brush. Methods Start by pulling out a four-celled Styrofoam quad, using the opaque tape labeling the quad with the name of the group, the date, and plant name Brassica rapa. Add potting soil to each celled quad

grown in the appropriate substrate, it would release a substance with antibiotic properties. Fleming admitted his discovery of penicillin was an accident. (he accidentally left a Petri dish open) Black and white image of Alexander Fleming in his laboratory. Fleming accidentally discovered penicillin when he left a petri dish open over night. 9. Cotton Gin The cotton gin was invented by Eli Whitney in 1793 and revolutionised the cotton industry in the United States. The machine quickly and easily

Abstract Cloud computing is a term that refers to sources and computer systems available on demand through the network, which can provide a number of computer services integrated without being restricted local resources in order to make it easier for the user and include those resources space for data backup and synchronization self also includes processing capabilities software and scheduling of tasks and push e-mail and remote printing, and the user can control when it is connected to the network

Regeneration is a process that regrows and repairs parts of the body that are lost or injured. This process mostly occurs in certain types of animals like worms, starfish and sea cucumbers, but regeneration can occur in every species. The type of regeneration differs, as planaria can regenerate their entire body, as humans can only regenerate cells and certain body organs, such as the liver (Chen et al. 1991). Regeneration is important to the animal because it is involved in functionality, and without

scarlet fever, from infections of the bones, throat, stomach or, brain. Many of us would not be here today had it not been for the discovery of penicillin. In 1928, Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug for

The mystery organism was inserted onto the petri dish on February 10, 2015 and took approximately 2 months to development and become visible without the use of a microscope. In the first observation, striations were visible on the brown, rounded seed/spore like organism under 10x magnification. In the second observation, green pigments were visible on the organism and clear, root/hair like structures were visible under 10x magnification. The spores have germinated and has begun to develop into

Substrate Preference of Non-Protein fed and Protein fed Musca domestica Justin Yeung ENY3005L, Julianna Xu Due: November 5th, 2014 Introduction Section Questions 1. What are you experimenting on (organism)? For this experiment, we chose Musca domestica L., the house fly, as our organism. 2. What is the topic of the experiment? The topic of this experiment is to examine the habitat preferences of two differently reared Musca domestica in a controlled environment among three substrates. 3. Why
