Ethnic Conflicts in Southeast Asia
From the writer: This quantity examines assorted ethnic configurations and clash avoidance and backbone in 5 assorted Southeast Asian international locations. * Tin Maung Maung Than lines the background and impossibility of the present Myanmar regimes quest to combine some of the ethnic teams within the border areas whereas insisting on a unitary country with all actual energy saved to themselves.

Sample text
In copper, simple and leaded brasses, and bronzes. The following elements, each present in amounts up to at least the concentration stated, do not interfere: 0-1 per cent of bismuth or phosphorus, 0*5 per cent of arsenic or manganese, and 1 per cent of iron or nickel. 1. 1. Special Reagents STANDARD ANTIMONY SOLUTION. Dissolve 0 1 g of antimony in 15 ml of cone, hydrochloric acid and 2 ml of cone, nitric acid ; warm to assist solution of the antimony, then cool. Make all dilutions with cone, hydrochloric acid.
Filter the ether extract through a dry N o . 41 Whatman paper (9 cm) into a dry 1-cm cell, and immediately measure the optical density at a wavelength of 553 ηιμ. 3. Procedure. Transfer 0-1 g of the sample (Note) to a beaker (50 ml), add 5 ml of cone, hydrochloric acid and 1 ml of cone, nitric acid, then continue as described under Preparation of Calibration Graph. Calculate the antimony content of the sample, using the calibration graph. REPRODUCIBILITY: 0-002 AT 0 0 2 PER CENT LEVEL NOTE. This weight of sample is suitable for antimony contents up to about 0-025 per cent.
Where larger amounts of antimony are present, use a 0-1-g sample, dissolve as stated, dilute the solutions to 100 ml with cone, hydrochloric acid, and take an aliquot containing about \5μgoΐ antimony. CHAPTER 6 ARSENIC SEVERAL methods are available for determining arsenic in non[ 3 4] ferrous materials. In B S 1 8 0 0 * two procedures are given; one, suitable for determining arsenic above about 0 - 2 per cent, is based on distillation (and iodimetric titration) of arsenous chloride from a solution containing ferric chloride, calcium chloride and hydrochloric acid.
