Contributors to Microbiology Pioneers of Microbiology I. Antonie van Leeuwenhoek (Oct. 24‚ 1632- Aug. 30‚ 1723) A. In 1676 Leeuwenhoek saw tiny organisms in water‚ he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes‚ blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work

ABSTRACT Heats of neutralization of sulphuric and hydrochloric acids by sodium hydroxide have been determined‚ using a microcalorimeter of the Tian-Calvet type. The range of concentrations employed was 5x10-" N to 3x10-* N‚which is sufficiently low to permit an accurate extrapolation to be

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

While there are many means of achieving this‚ two of the most common are prolonged boiling in a strong acid (acid-HVP) or strong base or using an enzyme such

DPOP and NPOP together evaluate the risk posed to humans by fire at landfills. DPOP measures the distance between the 297 landfill and the nearest building used by people for residential‚ occupational‚ educational‚ or recreational purposes. DPOP 298 score is calculated using Equation 30. For distance greater than 3057 m‚ DPOP = 0. If the distance is 0‚ then maximum 299 DPOP = 4.613. 300 DPOP = 4.613 x exp(-0.0005 x distance) (30) 301 3.8 Population within 3 km radius (NPOP) 302 NPOP‚ as per Equation

Peptide synthesis – chemistry and modifications Peptides and proteins exhibit the largest structural and functional variation of all classes of biologically active macromolecules. Biological functions as diverse as sexual maturation and reproduction‚ enzyme inhibition‚ blood pressure regulation‚ glucose metabolism‚ thermal control‚ analgesia and learning and memory are now thought to be regulated by peptides. Peptide synthesis chemistry Synthetic peptides are valuable tools in analysis of
