The History and technology of Opalotypes Fig 1; Unknown‚ date unknown Opalotype 383 x 280mm; From the collection of CCMC; Introduction The Opalotype consists of almost any photographic technique as long as it used on opal glass. It was in use from the mid 1800 ’s through to the1930 ’s and most of the methods of photographic production that were used during the 19th century were tried out with opalotypes. However despite it ’s long-lived history‚ Opalotypes are sadly treated as a very minor

EXPERIMENT NO. 12 DIGESTION IN THE STOMACH ABSTRACT____________________________________________________________________________ Digestion refers to the mechanical and chemical breakdown of food into smaller components that can undergo absorption. The objective of this experiment is to investigate mainly the process of digestion in the stomach. The conditions at which the enzymes responsible for the digestion process were determined. Also‚ the total and free acidity of gastric juice of the sample

2.3.7. Antibacterial activity on wound dressing: Two samples of wound dressing was treated with micro encapsulated extract of the pelargonium hortorum with sodium alginate‚ then one of the samples is post treated with citric acid. Each sample was independently examined towards antibacterial activity using two types of micro-organisms (Escherichia coli AATCC 2666 gram negative (ve) and Staphylococcus aureus AATCC 6538 gram positive (+ve)). The result was taken after 4 hours‚ 8 hours and after 24 hours

respiratory alterations in acid-base balance are managed by controlling ventilation. Metabolic changes are managed by treating the underlying problem‚ e.g.: hypoxia‚ shock‚ infection‚ diabetic ketoacidosis‚ inborn error of metabolism‚ etc. The use of alkali‚ e.g. bicarbonate‚ is controversial: there is evidence that it can be detrimental. However‚ in severe acidosis‚

Kassandra Coan Why put lime in a pond? Honors Activity 5.4 Lime is a commercial name for calcium oxide (CaO). When carbon dioxide (Co2) is removed from limestone‚ coral‚ seashells‚ or chalk they become lime. This product is easily accessible‚ because an abundance of limestone in found in the crust of the earth‚ and the Co2 is removed simply by heating the limestone. See formula below: 500-600

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.
