The absorption of sulphur dioxide in chloride and bromide containing electrolyte solutions was measured up to ionic strengths of 5 mol/dm. The thermodynamic equilibrium of the gas phase and the liquid phase was characterized by UV spectroscopy. UV spectra analysis gave strong evidence for SO2X complexes existing in the solutions. Consequently, these compounds were implemented in the reaction sc...

IN Part V [Gulland and Randall, 1935] it was shown that the molecule of the oxytocic hormone certainly contains one, and may possibly contain two, oxidation-reduction systems, although the existence of the second is not definitely established. The present communication describes the actions on the hormone of some oxidising and reducing agents, which were studied in the hope that they might thro...

the main cause for concern about global warming and climate change. Primary air pollutants include carbon monoxide (CO), carbon dioxide, water vapour and un-burnt fuel, hydrocarbons, including volatile and non-volatile organic compounds, oxides of nitrogen, sulphur dioxide (traces), and particulate matter. Pollutants, such as small particles arise not only from the exhaust but also from the roa...

The polarographic or voltammetric behaviour of a selected group of tetra-alkyl ammonium halides and related compounds in liquid sulphur dioxide was investigated, using a stationary disk platinum indicating micro-electrode and a silver/silver-bromide reference electrode withcompensation for the IR drop of the solution. The electrochemical oxidation-reduction patterns are characteristic of the na...

This study investigated whether chronic airflow limitation and rapid decline in pulmonary function were associated with peak exposures to ozone and other irritant gases in pulp mills. Bleachery workers potentially exposed to irritant gassings (n = 178) from three Swedish pulp mills, and a comparison group of workers not exposed to irritant gassings (n = 54) from two paper mills, were studied. B...

ABSTRACT- Drying has been used for the preservation of fruits since ancient times. Dried apricot reduces the damages, weight and volume losses, packaging space, storage and handling costs. In this paper, the effects of hot air dryer on an Iranian apricot cultivar ”Noori” have been investigated. The experiment was conducted at three temperatures (30, 40 and 50oC), three fruit thicknesses (5, 10 ...
