AERATION AND MODE OF NUTRIENT DELIVERY AFFECTS GROWTH OF PEAS IN A CONTROLLED ENVIRONMENT by Joseph Francis Romagnano

The development of a plant growth chamber capable of sustaining plant growth over multiple generations is a necessary step towards the attainment of a Controlled Ecological Life Support System (CELSS). The studies herein examine the effects of aeration abilities and rates on plants grown in three model nutrient delivery systems during germination and over the life-cycle of the plant. These stud...

Francis Home and Joseph Black: the Chemistry and Testing of Alkaline Salts in the Early Bleaching and Alkali Trade

This paper considers the analytical work of two chemists in Scotland during the second half of the 18 century. It examines their efforts to understand and determine the strength of alkaline salts at a time when quantitative analytical measurement was beginning to be made in a form recognizable by present day chemists. In this period atomic weights and chemical formulae, which we now regard as e...
