Attitudes of North Dakota High School Students Toward the Farm Crisis
This was a discussion of how farm crisis affected North Dakota high school students in their career choices. Knowing more about how economic stress may influence adolescent career choice, knowing more about adolescent attitudes towards and their awareness of the farm crisis could help parents and educators provide adolescents with more accurate information concerning the farm economy. A survey was taken asking teens their attitudes towards farming. Both teens form rural and urban settings opted for college. The article then breaks down the differences in responses based upon gender and other factors.
Stress and Self-Esteem Among Urban and Rural Adolescents in North Dakota
This article intends to gain access into those things affecting the stress levels and self-esteem of both rural and urban North Dakota adolescents and to discover if there were any variations between the two groups. The criteria for this study is detailed. A reduction in self-esteem may reduce an adolescents’ motivation for success. Tough economic situation at home is a factor. Adolescents model their parents’ behaviors regarding stress.
Selective and sensitive TNT sensors using biomimetic polydiacetylene-coated CNT-FETs.
Miniaturized smart sensors that can perform sensitive and selective real-time monitoring of target analytes are tremendously valuable for various sensing applications. We developed selective nanocoatings by combining trinitrotoluene (TNT) receptors bound to conjugated polydiacetylene (PDA) polymers with single-walled carbon nanotube field-effect transistors (SWNT-FET). Selective binding events between the TNT molecules and phage display derived TNT receptors were effectively transduced to sensitive SWNT-FET conductance sensors through the PDA coating layers. The resulting sensors exhibited an unprecedented 1 fM sensitivity toward TNT in real time, with excellent selectivity over various similar aromatic compounds. Our biomimetic receptor coating approach may be useful for the development of sensitive and selective micro- and nanoelectronic sensor devices for various other target analytes.
