Silica was the sole exposure found to be related to lupus in three case management illness. Exposure to particulate silica (crystalline silica or quartz) most ordinarily comes from mining and “dusty trades” like sandblasting‚ granite cutting‚ construction work‚ cement work‚ brick and tile laying (Parks CG‚ 2002).

tricalcium aluminate (Ca3Al2O6). When water is added‚ a number of complex hydration reactions take place. A typical idealized reaction can be represented as 2 Ca2SiO4(s) + 4 H2O(l) Ca3Si2O7. 3H2O(s) + Ca(OH)2(s). The hydrated silicate‚ called tobermorite gel‚ forms strong crystals that adhere by means of strong silicon-Oxygen bonds to the sand and aggregate (small rocks) that are mixed with the cement. Because the other product in this reaction is Calcium hydroxide‚ the mixture should be treated as a corrosive

Acetylation of Ferrocene 17. October 1996 Experiment #7 Introduction In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process had worked we employed: IR spectra analysis‚ column chromatography‚

when placed in a gel-electrophoresis box. Restriction endonucleases are critical tools in recombinant DNA methodology. Electrophoresis is the method of determining the size of fragments that are cut by restriction enzymes. These restriction enzymes always cut at their specific protein recognition sites. This is very useful in the sense that no two restriction enzymes codes for exactly the same recognition site‚ giving it a unique characteristic that is specific for a strand of DNA.

Each individual cell is covered in a hardened frustule made from silica. They are both alike in that they are both protists. However‚ dinoflagellates are a part of a group called alveolates. They are most common in marine and freshwater phytoplankton. Some are heterotrophic. Diatoms‚ on the other‚ are a part of a group called stramenopiles. They are unicellular‚ photosynthetic algae with cell walls that contain silica. Dinoflagellates are a diverse group of flagellate

In 1871‚ Grand Prismatic Spring was discovered and named by the Hayden Expedition for its striking coloration. Later‚ many geologists‚ traveled to the area to confirm the colors described by explorers and trappers. Grand Prismatic Spring is noted for being the largest hot spring in Yellowstone National Park and third largest in the world. The spring is located halfway between the Upper and Lower Geyser Basins. The central location provides dramatic scenery for Yellowstone’s fast visitors. The spring

Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed. ABSTRACT

ACKNOWLEDGEMENTS It is usually said that no man is an island unto himself‚ and any man who so lives all by himself‚ without interacting with his fellow men is in the words of Aristotle‚ “either a beast or a god”. Mutual co-operation and interaction form the cardinal feature of human life. The task of writing this report has not‚ in the least‚ been an easy one‚ and it would be axiomatic to add that all the numerous tasks involved could not be have been accomplished successfully singly
