One hundred and fifty-one weanling rats of both sexes were fed
control diets or diets containing 160 ppm diethylnitrosamine (DEN) or
150 ppm N-2-fluorenyl-acetamide (FAA). The carcinogen level was
calculated so that the LD₅₀ should be achieved at about 17 weeks.
Each carcinogen treatment was incorporated with three different diet...
Microfinance, or the technique of lending small amounts of money to the world’s poor for productive activities, has become a popular strategy for poverty-alleviation, achieving legislative status as a development strategy in the U.S. in 2000 with the Microenterprise for Self-Sufficiency Act. However, microfinance has increasingly failed to achieve the...
Lead zirconate titanate (PZT) is well known to exhibit some of the strongest piezoelectric responses, explaining why it is at the heart of piezoelectric-based microelectromechanical systems (MEMS) research. The use of pulsed laser deposition (PLD) to synthesize PZT offers many advantages over alternative deposition techniques, mainly regarding its ability to...
Microfinance, or the technique of lending small amounts of money to the world's poor for productive activities, has emerged as a dominant approach to poverty alleviation among international development organizations. However, consensus does not yet exist as to the best mechanism for delivery of loans. While most organizations simply offer...
Apologia is a rhetorical genre of self-defense. As such, apologetic discourse
involves a response to an attack upon an individual's character or worth as a human being.
Los Angeles Police Detective Mark Fuhrman encountered such a attack during the 0.J.
Simpson murder trial. The purpose of this analysis is to...
Post World War II victory culture and its fallout-the consensus ideology-led to the creation of a middle class willing to conform to a prescribed set of ideals, safely removed from all danger, and enjoying the material benefits of a growing middle-class income bracket. Walt Disney and Hugh Hefner, two seemingly...
Oogenesis in the sea urchin Strongylocentrotus purpuratus was
studied at the fine structural level, with special emphasis on the relationship
between the two main cell types within the ovary: the egg cells
and the nutritive phagocytes, or accessory cells. The nutritive
phagocytes are flagellated cells with extensive pseudopods which store...
Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...
This white paper investigates methods to conduct effective and efficient process development within the context of the NSF funded construction of the Ocean Observatory Facility.
The basis of this process development investigation was the CGSN Sensor Life Cycle project. During the course of this project the sensor life process was...
