A cloud-chamber study of the disintegration of oxygen and nitrogen
A study of the disintegration of nitrogen and oxygen when bombarded by neutrons has been made by means of a cloud chamber. By observing the particles produced in the disintegration of the oxygen and nitrogen nuclei, data have been taken on several phenomena; the energy levels of carbon-13, …

The effect of oily waste and nutrient amendments on soil fertility and oat growth
Growth chamber and incubation experiments were conducted with a sandy, marginal agricultural soil from the Brown soil zone near Richmound, Saskatchewan. The objective of the study was to determine how oily waste from heavy oil upgrader affects soil fertility, plant growth and microbial activity …

Growth loss of loblolly pine (Pinus taeda L.), white pine (P. strobus L.) and sycamore (Platanus occidentalis L.) proximal to a periodic source of air pollution
… in the second white pine stand. A field chamber study (utilizing charcoal filtered and nonfiltered air) with seedlings of red oak, sycamore, sweetgum, yellow poplar, white ash, green ash, and Virginia pine indicated significant inhibition of terminal elongation in Virginia pine and red …

Moisture Buffering in the Indoor Environment
… basic material properties to full scale climatic chamber measurements. A definition scheme regarding the moisture buffering in the indoor environment, at three spatial levels ?material, component and room level, is proposed. Within the project, a method, to determine sorption isotherms has been …

Water Relations of Ponderosa Pine in Contrasting Environments: Implications for Global Climate Change
… to prevent xylem embolism induction. A growth chamber study revealed that there were no interactions between elevated CO2 and temperature on water transport. Similar to their adult counterparts in the field, ponderosa pine seedlings reduced AL/AS and had higher KL in response to elevated …

Emissions of Phthalate Plasticizer from Polymeric Building Materials
… sources and pathways of exposure. In this study, a model that integrates the fundamental mechanisms governing emissions of semi-volatile organic compounds (SVOCs) from polymeric materials and their subsequent interaction with indoor surfaces and airborne particles was developed. The …
