Stephen Gray e a descoberta dos condutores e isolantes: tradução comentada de seus artigos sobre eletricidade e reprodução de seus principais experimentos

O livro expõe a trajetória de Stephen Gray (1666‑1736), cientista inglês que dedicou sua vida à Astronomia e à Física, especificamente na área da Eletricidade, e realizou uma série de experimentos que levaram a conclusões inéditas para a época. Sua principal descoberta foi perceber que existem dois tipos de substâncias com propriedades elétricas muito distintas, hoje conhecidas como condutores e isolantes. A obra mostra que Gray foi o primeiro cientista da história a atribuir aos metais e outros condutores a propriedade de atrair corpos leves colocados em suas proximidades, fenômeno que atualmente é conhecido como indução ou polarização elétrica. E também o pioneiro na criação de eletretos, substâncias que apresentam uma eletrização de longa duração, mostrando ainda como preservar temporalmente a eletrização dos corpos. Os autores apresentam uma breve biografia do cientista Stephen Gray, que apesar de sua importância permanece bastante desconhecido dos pesquisadores contemporâneos, principalmente brasileiros, uma vez que seus escritos e experimentos carecem de divulgação no país. Por conta dessa condição, a obra traz a tradução de seus dez artigos sobre eletricidade. Os experimentos de Gray são contextualizados, ilustrados com figuras didáticas e explicados com base nos conhecimentos atuais da Física. O livro mostra também como reproduzir os principais experimentos do cientista inglês com a utilização de materiais de baixo custo. De acordo com os autores, com o objetivo de motivar outros cientistas a se aprofundarem nessas pesquisas e a desenvolverem a obra de Gray de forma que seja utilizada no ensino, o livro busca “resgatar a memória desse grande pesquisador, que tinha um olhar afiado, era bastante preciso em suas explicações, criativo em suas ideias e muito claro em seus textos”

Gibberellic acid, ozone and 1-methylcyclopropene on the gray mold control in avant garde rose

Gray mold caused by Botrytis cinerea is considered the major disease of greenhouse grown flowers. The goal of this study was to evaluate the effects of gibberellic acid (GA3), ozone, and 1-MCP, applied on postharvest, on the gray mold control in 'Avant Garde' rose. Rose flowers were artificially inoculated with B. cinerea (104 conidia ml-1) and non-inoculated. After treatments, roses were stored under room conditions (20±2°C/80±5% RH) and checked for gray mold incidence and severity. Spraying of GA3 at 25, 50, and 75 mg L-1 on non-inoculated roses reduced the area under the disease progress curve (AUDPC) of gray mold incidence in 41, 40 and 54%, respectively. Continuous application of ozone at 2.7 ppm reduced 14-folds B. cinerea sporulation. On the other hand, 1-MCP did not control gray mould in rose. These results showed that GA3 sprays and ozone contribute to postharvest control of gray mold in cut rose and can be utilized on integrated disease management.

Baleen Whales: Conservation Issues and The Status Of The Most Endangered Populations

Most species of baleen whales were subject to intensive overexploitation by commercial whaling in this and previous centuries, and many populations were reduced to small fractions of their original sizes. Here, we review the status of baleen whale stocks, with an emphasis on those that are known or thought to be critically endangered. Current data suggest that, of the various threats potentially affecting baleen whales, only entanglement in fishing gear and ship strikes may be significant at the population level, and then only in those populations which are already at critically low abundance. The impact of some problems (vessel harassment, and commercial or aboriginal whaling) is at present probably minor. For others (contaminants, habitat degradation, disease), existing data either indicate no immediate cause for concern, or are insufficient to permit an assessment. While the prospect for many baleen whales appears good, there are notable exceptions; populations that are of greatest concern are those suffering from low abundance and associated problems, including (in some cases) anthropogenic mortality. These include: all Northern Right Whales Eubalaena glacialis, Bowhead Whales Balaena mysticetus of the Okhotsk Sea and various eastern Arctic populations, western Gray Whales Eschrichtius robustus, and probably many Blue Whale Balaenoptera musculus populations. We review the status of these populations and, where known, the issues potentially affecting their recovery. Although Humpback Whales Megaptera novaeangliae and Southern Right Whales Eubalaena australis were also heavily exploited by whaling, existing data indicate strong recovery in most studied populations of these species.

Book Review of Determining the Economic Value of Water: Concepts and Methods by Robert A. YoungBook Review of Determining the Economic Value of Water: Concepts and Methods by Robert A. Young

Water has been and will continue to be a contentious issue for policy makers, landowners, municipalities, environmentalists, and citizens who feels they have an undeniable right to clean water delivered to their homes (at least in the United States). With so many groups coming into conflict over what, at least in the West and the Great Plains, continues to be a diminishing resource per capita, an understanding of the economic value of this resource is critical. It is important to note, as Robert Young does throughout his book, that the true economic value of water goes beyond what we pay our city services each month, or the cost to farmers or ranchers for pumping and distributing that water on their land. The value of water must take into account the value of the competing uses which are sometimes difficult to price.

Review of This Land: A Guide to Central National Forests by Robert H. Mohlenbrock

Robert Mohlenbrock's guide to the national forests of the central U.S. provides the traveling naturalist with a wealth of information on the wide array of national forest lands in the heart of the country. Part of a three-volume series of field guides, this volume covers the states of Louisiana, Minnesota, Missouri, Montana, Nebraska, New Mexico, South Dakota, Texas, and Wyoming. While most of the forests are along the western and eastern borders of the Great Plains, readers will find a detailed travelog for a National Forest within a day's drive of most areas within the region. While not the focus of this volume, a brief mention of the National Grasslands of the Great Plains would have made it more comprehensive for the traveling naturalist.

Landscape-Genetic Analysis of Population Structure in the Texas Gray Fox Oral Rabies Vaccination Zone

In west-central Texas, USA, abatement efforts for the gray fox (Urocyon cinereoargenteus) rabies epizootic illustrate the difficulties inherent in large-scale management of wildlife disease. The rabies epizootic has been managed through a cooperative oral rabies vaccination program (ORV) since 1996. Millions of edible baits containing a rabies vaccine have been distributed annually in a 16-km to 24-km zone around the perimeter of the epizootic, which encompasses a geographic area >4 x 105 km2. The ORV program successfully halted expansion of the epizootic into metropolitan areas but has not achieved the ultimate goal of eradication. Rabies activity in gray fox continues to occur periodically outside the ORV zone, preventing ORV zone contraction and dissipation of the epizootic. We employed a landscape-genetic approach to assess gray fox population structure and dispersal in the affected area, with the aim of assisting rabies management efforts. No unique genetic clusters or population boundaries were detected. Instead, foxes were weakly structured over the entire region in an isolation by distance pattern. Local subpopulations appeared to be genetically non-independent over distances >30 km, implying that long-distance movements or dispersal may have been common in the region. We concluded that gray foxes in west-central Texas have a high potential for long-distance rabies virus trafficking. Thus, a 16-km to 24-km ORV zone may be too narrow to contain the fox rabies epizootic. Continued expansion of the ORV zone, although costly, may be critical to the long-term goal of eliminating the Texas fox rabies virus variant from the United States.

Activation of 5-HT2C receptors in the dorsal periaqueductal gray increases antinociception in mice exposed to the elevated plus-maze

Several findings have pointed to the role of the dorsal periaqueductal gray (dPAG) serotonin 5-HT1A and 5-HT2(A-C) receptor subtypes in the modulation of defensive behavior in animals exposed to the elevated plus-maze (EPM). Besides displaying anxiety-like behavior, rodents also exhibit antinociception in the EPM. This study investigated the effects of intra-dPAG injections of 5-HT1A and 5-HT2B/2C receptor ligands on EPM-induced antinociception in mice. Male Swiss mice received 0.1 mu l intra-dPAG injections of vehicle, 5.6 and 10 nmol of 8-OHDPAT, a 5-HT1A receptor agonist (Experiment 1), or 0.01, 0.03 and 0.1 nmol of mCPP, a 5-HT2B/2C receptor agonist (Experiment 2). Five minutes later, each mouse received an intraperitoneal injection of 0.6% acetic acid (0.1 ml/10 g body weight; nociceptive stimulus) and was individually confined in the open (OA) or enclosed (EA) arms of the EPM for 5 min, during which the number of abdominal writhes induced by the acetic acid was recorded. While intra-dPAG injection of 8-OHDPAT did not change open-arm antinociception (OAR). mCPP (0.01 nmol) enhanced it. Combined injections of ketanserin (10 nmol/0.1 mu l), a 5-HT2A/2C receptor antagonist, and 0.01 nmol of mCPP (Experiment 3), selectively and completely blocked the OAR enhancement induced by mCPP. Although intra-dPAG injection of mCPP (0.01 nmol) also produced antinociception in EA-confined mice (Experiment 2), this effect was not confirmed in Experiment 3. Moreover, no other compound changed the nociceptive response in EA-confined animals. These results suggest that the 5-HT2C receptors located within the PAG play a role in this type of environmentally induced pain inhibition in mice. (c) 2012 Elsevier B.V. All rights reserved.
