A Generic Autonomous Clustering-Based Heterogeneous Waveband Switching Architecture in WDM Networks

Heterogeneous waveband switching (HeteroWBS) in WDM networks reduces the network operational costs. We propose an autonomous clustering-based HeteroWBS architecture to support the design of efficient HeteroWBS algorithms under dynamic traffic requests in such a network.

New Studies Initiated by the U.S. Geological Survey— Effects of Nutrient Enrichment on Stream Ecosystems

In 2001, the U.S. Geological Survey’s National Water-Quality Assessment (NAWQA) Program began an intensive study of nutrient enrichment—elevated concentrations of nitrogen and phosphorus— in streams in five agricultural basins across the Nation (see map, p. 2). This study is providing nationally consistent and comparable data and analyses of nutrient conditions, including how these conditions vary as a result of natural and human-related factors, and how nutrient conditions affect algae and other biological communities. This information will benefit stakeholders, including the U.S. Environmental Protection Agency (USEPA) and its partners, who are developing nutrient criteria to protect the aquatic health of streams in different geographic regions.

A Qualitative Analysis of Youth Feedback of Nutrition School Enrichment Kits in Lincoln, NE

A Qualitative Analysis of Youth Feedback of Nutrition School Enrichment Kits in Lincoln, NE Richard A. Losey, M.S. University of Nebraska, 2010 Advisor: Wanda M. Koszewski The qualitative analysis of the responses given by students participating in classrooms that used the Nutrition Education Program‟s (NEP) school enrichment kits was the primary focus of this research. Data was collected from the participants in written form. Three major themes appeared during analysis of the data, healthy eating habits, cleanliness and change. The theme of healthy eating habits is comprised of the following sub-themes: breakfast, nutrients, label reading, Food Guide Pyramid/MyPyramid and healthy snacks. Cleanliness is comprised of hand washing and food safety sub-themes. The change theme is made up of change in healthy eating habits, change in cleanliness and change in both healthy eating habits and cleanliness. The data suggests that participating students have made or intend to make changes regarding healthy eating habits and cleanliness, which is the goal of nutrition education. The students‟ responses indicate that the NEP school enrichment kits are effective in increasing the knowledge of students and promoting healthy lifestyle changes.

EREMOPHYGUS BICOLOR (GUTIÉRREZ) (COLEOPTERA: SCARABAEIDAE: RUTELINAE: RUTELINI): A NEW TRIBAL AND GENERIC PLACEMENT FOR THE BOLIVIAN SCARAB PLATYCOELIA BICOLOR (GUTIÉRREZ) (ANOPLOGNATHINI)

Platycoelia bicolor (Gutiérrez) (Scarabaeidae: Rutelinae) is transferred from the tribe Anoplognathini, subtribe Platycoeliina, to the tribe Rutelini. Platycoelia bicolor is placed in the genus Eremophygus Ohaus and the taxonomic history of the species is discussed. The transfer creates a new combination, Eremophygus bicolor (Gutiérrez) and places the generic name Heterocallichloris Gutiérrez as a junior synonym of Eremophygus (new synonymy). Morphological characters that warrant the transfer are discussed. Se transfiere Platycoelia bicolor (Gutiérrez) (Scarabaeidae: Rutelinae) de la tribu Anoplognathini, subtribe Platycoeliina, a la tribu Rutelini. Se transfiere Platycoelia bicolor al género Eremophygus Ohaus y se discute su historia taxonómica. La transferencia crea una nueva combinación, Eremophygus bicolor (Gutiérrez) y ubica al nombre genérico Heterocallichloris Gutiérrez como un sinónimo junior de Eremophygus. Se discuten los caracteres morfológicos que justifican la transferencia.
