Addition of the methylcarbamate compounds p-chlorophenyl
N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate
(carbaryl) to various herbicides has resulted in reduced rates of
degradation. Carbaryl affects the degradation of certain herbicides
in both plants and soils while PPG-124 has only been demonstrated
to affect degradation in soils. Both these materials are effective...
The determination of failure is complicated when a structural
element is subjected to combined rather than simple stresses. This
is especially true when the principle of superposition does not apply.
For such cases, tests of the element under the expected loads are
required to determine its failure criteria.
In this...

Decomposition of forest litter is a complex process
involving interactions between physical, chemical and
biological factors. As litter decomposes it is chemically
altered. Cation exchange capacities of litter represent a
means of characterizing the number of hydrophilic acid
groups. Some kind of soil-root ion exchange mechanisms are
utilized by the...

Symbiotic associations are established between non-leguminous
(actinorrhizal) nitrogen-fixing flowering plants and two categories
of microorganisms: mycorrhizal fungi and a filamentous actinomycete.
The actinomydete induces nodule formation and produces nitrogenase,
the enzyme responsible for the reduction of atmospheric nitrogen to
a form available to higher plants. The mycorrhizal fungus is found...
