Villiers de l’Isle-Adam (1838-1889) is always remembered and admired for his books: Contes cruels, L’Ève future and Claire Lenoir- which summarize the main worries of the writer, his satire of the triumphant Positivism, his metaphysical theory and his aspiration for the Ideal. He is one of the greatest artisans of the French literature style of the XIX century and, in spite of some individual and particular characteristics, he shares with other writers from his time – Joris-Karl Huysmans, Barbey d’Aurevilly, Leon Bloy, among others – the same sorrow and fury towards Positivism and Mercantilism. Having as a starting point the collection Contes cruels, the purpose of this article is to reveal the author’s writings who, by searching for the Ideal and by taking refuge in art, is able to unite the poet, the ironic and the idealist philosopher. Through his writings, the writer moves away from the world’s mediocrity and can express a mix of revolt, reaction, rebellion and also, his hopes expressed in his beliefs in the “Au-delà” and in the salvation by the Ideal.

The desert locust (Schistocerca gregaria) has been used as material for numerous cytogenetic studies. Its genome size is estimated to be 8.55 Gb of DNA comprised in 11 autosomes and the X chromosome. Its X0/XX sex chromosome determinism therefore results in females having 24 chromosomes whereas males have 23. Surprisingly, little is known about the DNA content of this locust's huge chromosomes. Here, we use the Feulgen Image Analysis Densitometry and C-banding techniques to respectively estimate the DNA quantity and heterochromatin content of each chromosome. We also identify three satellite DNAs using both restriction endonucleases and next-generation sequencing. We then use fluorescent in situ hybridization to determine the chromosomal location of these satellite DNAs as well as that of six tandem repeat DNA gene families. The combination of the results obtained in this work allows distinguishing between the different chromosomes not only by size, but also by the kind of repetitive DNAs that they contain. The recent publication of the draft genome of the migratory locust (Locusta migratoria), the largest animal genome hitherto sequenced, invites for sequencing even larger genomes. S. gregaria is a pest that causes high economic losses. It is thus among the primary candidates for genome sequencing. But this species genome is about 50 % larger than that of L. migratoria, and although next-generation sequencing currently allows sequencing large genomes, sequencing it would mean a greater challenge. The chromosome sizes and markers provided here should not only help planning the sequencing project and guide the assembly but would also facilitate assigning assembled linkage groups to actual chromosomes.

This work is the fruitful result of the desire to conduct a collaborative investigation through Circus Arts with children and adolescents at social (vulnerability) risk. Thus, the very objective of the rese arch was to analyze and understand Social Circus action possibilities on non-formal education as a (viable) job option for Physical Education teachers. This research was developed through qualitative research using Field Notes as the main instrument for the meetings' data collection, which took place from May to December 2015. In general terms, the research was divided into three phases, the former was carried out at a state school through the Escola da Família Program, (which consists of the opening of all public schools on weekends, offering to the communities extra activities) and the latter two in Shelter Homes for adolescents. The results showed that there were some (considerable) difficulties throughout and some gaps in our society that become evident on the poor. Furthermore, the results also confirm the possibility of the Physical Education teachers' participation in other sectors of the society, through the non-formal Education perspective and the possibility of Social Circus as the (fundamental) instrument of this action

O principal objetivo desse trabalho é investigar a influência dos parâmetros térmicos velocidade de solidificação (VL) e taxa de resfriamento (TR), nos espaçamentos dendríticos primários (λ1) da liga hipoeutética Al-7%Si, durante a solidificação direcional horizontal, em regime transiente. Os valores de λ1 foram medidos ao longo do comprimento do lingote e correlacionados com esses parâmetros. A variação dos espaçamentos dendríticos estudados é expressa por meio de funções na forma de potência de VLe TRdadas, respectivamente, por λ1= 55(VL)-1.1e λ1= 212 (TR)-0.55. Um estudo comparativo é realizado entre os resultados encontrados nesse trabalho e aqueles obtidos para a mesma liga quando solidificada direcionalmente nos sistemas verticais ascendente e descendente, sob as mesmas condições assumidas. Finalmente, os resultados experimentais obtidos são comparados com valores fornecidos por alguns modelos teóricos propostos na literatura para analisar espaçamentos dendríticos primários.

The U.S. Geological Survey (USGS) is committed to providing the Nation with credible scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov/). Information on the Nation’s water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation and is suitable for industry, irrigation, and fish and wildlife. Population growth and increasing demands for water make the availability of that water, now measured in terms of quantity and quality, even more essential to the long-term sustainability of our communities and ecosystems. The USGS implemented the National Water-Quality Assessment (NAWQA) Program in 1991 to support national, regional, State, and local information needs and decisions related to water-quality management and policy (http://water.usgs.gov/nawqa). The NAWQA Program is designed to answer: What is the condition of our Nation’s streams and ground water? How are conditions changing over time? How do natural features and human activities affect the quality of streams and ground water, and where are those effects most pronounced? By combining information on water chemistry, physical characteristics, stream habitat, and aquatic life, the NAWQA Program aims to provide science-based insights for current and emerging water issues and priorities. From 1991-2001, the NAWQA Program completed interdisciplinary assessments and established a baseline understanding of water-quality conditions in 51 of the Nation’s river basins and aquifers, referred to as Study Units (http://water.usgs.gov/nawqa/studyu.html).

We begin the 2001 Master Conservationist program with honorees in production agriculture from District A which includes the Panhandle of Nebraska. I would like to ask Leon and Cheryl Burkhart-Kriesel (Kresel) of Gurley who are unable to be present. They operated the family farm in partnership with Fred and Viola Kriesel until 1984 when Leon and Cheryl become sole owners/operators. The Kriesels produce certified wheat, millet, oats, and barley seed on 3200 dryland acres that are owned, rented, or contracted. Since 1984, 45,000 feet of terraces have been installed. Their holistic conservation plan also includes over 57,000 feet of windbreaks of mixed evergreen and broadleaf trees and shrubs. This mixture of plant species is unique in the Panhandle. They built an earthen dam with 11 acre-feet of permanent storage and 70.5 acre-feet of detention storage. Results include reduced soil erosion by wind and water, and increased productivity and wildlife populations. Local and international groups tour the farm. Congratulations to the Kriesels.

This NebGuide describes the two common spider mites found in Nebraska corn and soybeans, their natural enemies and management. Two species of spider mites, the Banks grass mite and twospotted spider mite, commonly feed on Nebraska corn. Banks grass mites (BGM) feed almost exclusively on grasses, including corn and sorghum. Twospotted spider mites (TSM) not only feed on many species of grasses, but also on soybeans, fruit trees and a variety of vegetables and ornamental plants. Although these two species are somewhat similar in appearance, they differ in several biological characteristics and in their susceptibility to pesticides. Banks grass mites usually appear earlier in the season, feed mostly on the lower leaves of the corn plant, and in Nebraska are moderately susceptible to many of the commonly used miticides. On the other hand, TSM tend to appear in mid to late season, increase rapidly, feed over the entire plant, and often are not consistently controlled by available pesticides.
