Potentially carcinogenic compounds may cause cancer through direct DNA damage or through indirect cellular or physiological effects. To study possible carcinogens, the fields of endocrinology, genetics, epigenetics, medicine, environmental health, toxicology, pharmacology and oncology must be considered. Disruptive chemicals may also contribute to multiple stages of tumor development through effects...
The effects of bicycle exercise on specific anthropometric and
physiological measures were observed in two test subjects (S1 and S2)
over a twelve week exercise period. The two subjects, one male (S1)
and one female (S2) participated in a graduated bicycle exercise program.
Body weight, body measurements, circulatory function tests,...
Research in warm-climate biomes has shown
that invasion by symbiotic dinitrogen (N₂)-fixing plants can
transform ecosystems in ways analogous to the transformations
observed as a consequence of anthropogenic, atmospheric
nitrogen (N) deposition: declines in biodiversity, soil
acidification, and alterations to carbon and nutrient cycling,
including increased N losses through nitrate...

Pacific whiting (Merluccius productus) is one of the most abundant fisheries on the American west coast. However, these fish are historically underutilized due to quality issues resulting from fillet softening that occurs as a result of both endogenous and exogenous (Myxosporidian parasite infection) cathepsin protease action during either storage (cathepsin...
The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...
The purpose of this study was to analyze the state of development of
adult education in Nigeria.
The major objectives were to review the state of development of
Nigerian adult education programs, assess the overall effectiveness of
these programs, and utilize the findings to suggest action for future
program improvement....
Inoculation trials were set up in fumigated nursery beds for red alder (Alnus rubra Bong.) seedling production. Frankia inoculum was applied in eight treatments: control, nodule suspension, and three levels of cell suspension (strain ArI5) applied with and without a peat carrier. Seedlings were evaluated at midseason and lifting. The...
This investigation explored the use of microcosms as a tool for
studying the dynamics of tropical aquaculture ponds. The potential use
of rabbit excreta as a pond fertilizer in integrated farming systems was
also investigated.
Twelve insulated fiber glass tanks were utilized as microcosms to
simulate earthen ponds. Seven hand-sexed...
In many partially glacierized watersheds glacier recession driven by a warming climate could lead to complex patterns of streamflow response over time, often marked with rapid increases followed by sharp declines, depending on initial glacier ice cover and rate of climate change. Capturing such “phases” of hydrologic response is critical...

In the highly competitive animal protein market, seafood faces increasing pressure to improve and standardize product quality. While there is general consensus that quality can be improved for many seafood products, there is little agreement on the types and levels of characteristics that should define "quality." This is a fundamental...
