Biologia de Doru luteipes (Scudder) e sua capacidade predatória de ovos de Helicoverpa zea (Boddie).

O objetivo deste trabalho foi estudar a biologia e o potencial de Doru luteipes (Scudder) em laboratório, cOmo predador de ovos de Helicoverpa zea (Boddie). Ninfas de um dia de idade e adultos foram individualizados em placas de Petri, receberam como alimento, ovos de H. zea. O período de incubação foi, em média. 7,6 dias. O período ninfal (quatro instares) foi de 34,4 dias. O ciclo total do inseto foi, em média, 217, 9 dias. O período pré-reprodutivo foi, em média. 30,7 dias, sendo que as fêmeas ovipositaram mais de uma vez, mesmo quando não fecundadas. O número de ovos por postura foi de 15,9, com aviabilidade chegando a 85,2%. A longevidade média do adulto, foi de 175,9 dias. Em média uma ninfa consumiu 23,7 ovos de H. zea por dia, num total de 812,9 ovos durante esta fase. Já o adulto do predador consumiu 7457,4 ovos, com média diária de 42,1 ovos. No geral, um predador se alimentou durante sua vida, de aproximadamente 8276 ovos de H. zea (39 ovos/dia)

Social-Cognitive Theories to Explain Physical Activity

Despite the widely recognized health benefits of physical activity, participation in regular physical activity falls far short of the Global Action Plan on Physical Activity 2018–2030. More than half of the population does not reach current recommendations, and around one-fourth is not sufficiently active at all. Understanding social-cognitive theories may aid in the creation of interventions to improve long-term physical activity maintenance. The current work covers theory and research on physical activity patterns. It specifically provides an overview of contemporary conceptualizations of motivational and cognitive theories, as well as reviews recent perspectives on how physical activity can be adopted and maintained. Key questions, such as whether physical activity can be executed purely based on cognitive functions, are also addressed. Furthermore, this review identifies possible and effective intervention strategies to promote physical activity.info:eu-repo/semantics/publishedVersio

The Six-Month List and the Unintended Consequences of Judicial Accountibility

A little-known mechanism instituted to improve judicial accountability and speed up the work of the federal judiciary has led to unintended consequences, many of them unfortunate. Federal district court judges are subject to a soft deadline known as the Six-Month List (the List). By law, every judge\u27s backlog (cases older than three years and motions pending more than six months) is made public twice a year. Because judges have life tenure and fixed salaries, a mere reporting requirement should not influence their behavior. But it does. Using the complete record of all federal civil cases between 1980 and 2017 and a hand-coded sample of summary judgment motions, we demonstrate that the List leads judges to close substantially more cases and decide more motions in the week immediately before it is compiled. While average motion processing time is shortened by ten to thirty days, duration is actually lengthened for some motions (those for which the deadline is least pressing). Moreover, we find suggestive evidence that the List has substantive consequences: in an effort to comply with the List, judges may be making more errors. Theory suggests that giving judges an incentive for faster case processing is probably a mistake. But because this incentive is Congressionally-mandated, it cannot be eliminated by the judiciary unilaterally. We offer an alternative mechanism that will limit distortions until Congress acts to relieve the federal courts of this unnecessary burden

Discrepancies in Determinations of the Ginzburg-Landau Parameter

Long-standing discrepancies within determinations of the Ginzburg-Landau parameter $\kappa$ from supercritical field measurements on superconducting microspheres are reexamined. The discrepancy in tin is shown to result from differing methods of analyses, whereas the discrepancy in indium is a consequence of significantly differing experimental results. The reanalyses however confirms the lower $\kappa$ determinations to within experimental uncertainties.Comment: submitted to Phys. Rev.

Genetic diversity among proso millet (Panicum miliaceum) biotypes assessed by AFLP technique.

A técnica de AFLP (Amplified Fragment Length Polymorphism) foi empregada para acessar a diversidade genética entre três biótipos domesticados e nove biótipos selvagens de proso millet dos Estados Unidos e do Canadá. Oito combinações de primers detectaram 39 fragmentos polimórficos de DNA, e a estimativa da distância genética entre os biótipos variou de 0,02 a 0,04. Colorado-Weld County de sementes pretas e Wyoming-Platte County foram os biótipos mais distintos de acordo com o índice de dissimilaridade. A análise de cluster por UPGMA revelou dois grupos distintos de proso millet mas sem nenhuma relação geográfica. Seis biótipos selvagens que exibiam algumas características de plantas cultivadas foram agrupados juntamente com os biótipos domesticados de proso millet, enquanto os três fenótipos tipicamente selvagens formaram outro grupo distinto por marcadores AFLP
