Large Scale Searches for Brown Dwarfs and Free-Floating Planets

Searches of large scale surveys have resulted in the discovery of over 1000 brown dwarfs in the Solar neighbourhood. In this chapter we review the progress in finding brown dwarfs in large datasets, highlighting the key science goals, and summarising the surveys that have contributed most significantly to the current sample.Comment: Accepted to appear in the Handbook of Exoplanets (Springer); Editors: Hans J.

Priorities for synthesis research in ecology and environmental science

Synthesis research in ecology and environmental science improves understanding, advances theory, identifies research priorities, and supports management strategies by linking data, ideas, and tools. Accelerating environmental challenges increases the need to focus synthesis science on the most pressing questions. To leverage input from the broader research community, we convened a virtual workshop with participants from many countries and disciplines to examine how and where synthesis can address key questions and themes in ecology and environmental science in the coming decade. Seven priority research topics emerged: (1) diversity, equity, inclusion, and justice (DEIJ), (2) human and natural systems, (3) actionable and use-inspired science, (4) scale, (5) generality, (6) complexity and resilience, and (7) predictability. Additionally, two issues regarding the general practice of synthesis emerged: the need for increased participant diversity and inclusive research practices; and increased and improved data flow, access, and skill-building. These topics and practices provide a strategic vision for future synthesis in ecology and environmental science

Computational Studies on the Pt(II)-Catalyzed Cycloisomerization of 1,6-dienes into Bicyclopropanes: A Mechanistic Quandary Evaluated by DFT.

The mechanism of the (bis(phosphanylethyl)phosphane)Pt(2+) catalyzed cyclo-isomerization reaction of 7-methyl-octa-1,6-diene to form 1-isopropylbicyclo[3.1.0]hexane was studied using computational methods. The cyclopropanation step was found to be the turnover-limiting step. The overall reaction proceeds via both a 5-exo and a 6-endo route. W conformations were shown to facilitate cyclopropanation, but do not have any influence on the rate of the 1,2-hydride shifts

Estudo com módulos auto-instrucionais como uma estratégia de ensino na disciplina de Enfermagem Neonatológica Estudio con módulos auto-instruccionales como una estrategia de enseñanza en la disciplina de enfermería neonatológica Study with selfinstructional modules as a teaching strategy in the neonatological nursing

Nota prévia de um estudo quase experimento com delineamento de série de tempo, que procura descrever uma estratégia de ensino na disciplina de enfermagem neonatológica, com módulos auto-instrucionais de exame físico do Recém-Nascido a Termo (RNT). O locus desta pesquisa é uma Universidade privada do Estado de São Paulo. Os participantes utilizarão módulos auto-instrucionais em forma de CD-ROM para aprendizagem do exame físico do RNT. Este estudo trará contribuição aos docentes de enfermagem e aos alunos quanto a auto aprendizagem e desenvolvimento da habilidade na realização do exame físico do RNT.<br>Nota previa de un estudio casi experimental con delineamiento de serie de tiempo que tiene como objetivo la estrategia de enseñanza de enfermería neonatal, con módulos auto-instruccionales en al examen físico de los Recién Nacidos a Término (RNT). El locus de esta pesquisa será en una Universidad privada del Estado de São Paulo. Los participantes irán utilizar módulos auto-instruccionales en forma de CD-ROM para el aprendizaje del examen físico del RNT. Esse estudio hará una contribuición a los docentes de enfermería y a los alumnos cuanto al auto-aprendizaje y desarrollo de la habilidad en l realización del examen físico del RNT.<br>This is a previous note of an almost experimental study with time series aiming teaching strategy in neonatal nursing discipline with self-instructional modules of physical examination in Full-Term Newborns Infant (TNBI). The site of this research will be a private University in the State of São Paulo. The particicipants will use CD-ROM self-instructional modules to learn how to perform physical examination in TNBI. This study will bring much contribution to the nursing academic staff regarding their self-learning and development in the ability to perform physical examination in TNBI
