Comportamento do fator de potência de uma serra de fita vertical e de um picador em uma serraria

This work aims to present the electrical behavior of two mechanical processing equipment of wood, the saw vertical tape and the wood chipper. Their characteristics in real operating conditions and the electrical behavior of devices in terms of energy efficiency is shown through the study of individual power factor are presented in this study. It was observed that both devices operate unloaded for some intervals of time and this contributes to a low power factor. It is concluded that improved production planning and better preparation of the operators in the operations of sawing wood, in order to improve the power factor in sawmills is necessary.

Interview with Richard Dinning

In his October 17, 2012 interview with Robert Ryals, Richard Dinning details his thoughts and memories as an army air corps cadet at Winthrop. Dinning includes details of his career in the Army Air Corp during WWII. This interview was conducted for inclusion into the Louise Pettus Archives and Special Collections Oral History Program.

Acetaminophen as an Oral Toxicant for Nile Monitor Lizards (Varanus niloticus) and Burmese Pythons (Python molurus bivittatus)

Context. Invasive species are a growing global problem. Biological invasions can result in numerous harmful impacts on local ecologies, and non-native herpetofauna are frequently ignored. Nile monitor lizards (Varanus niloticus) and Burmese pythons (Python molurus bivittatus, recently reassessed as Python bivittatus bivittatus), have become established in southern Florida. Both are large, semi-aquatic predators that pose serious threats to a variety of threatened and endangered species, as well as to the unique ecology of the area. Aims. Acetaminophen (CAS#103-90-2), a lethal oral toxicant for the invasive brown treesnake (Boiga irregularis) on Guam, was investigated as a possible toxicant in juvenile Burmese pythons and Nile monitors. Methods. Dead neonatal mouse (DNM) baits containing 0, 10, 20, or 40 mg acetaminophen were force-fed to Nile monitors, whereas DNM containing doses of 0, 20, 40, or 80 mg were freely consumed by Burmese pythons. Subjects were frequently observed post-treatment for general condition and position, with special attention paid to activity (if any), behaviour, respiration, bleeding, emesis, ataxia, and mortality. Key results. In Nile monitors, acetaminophen doses of 10, 20, or 40 mg resulted in 0, 50 and 100% mortality, respectively. In Burmese pythons, doses of 20, 40, or 80 mg resulted in 14.3, 85.7 and 100% mortality, respectively. No mortality was observed in control individuals of either species. A negative correlation between dosage (mg kg–1) and time-to-death was observed in both species. Dosages ranging from 522 to 2438 mg kg–1 and 263 to 703 mg kg–1 were uniformly lethal to monitors and pythons, respectively. Neither species exhibited signs of pain or discomfort following acetaminophen treatment. Conclusions. Acetaminophen is an effective toxicant in juvenile Nile monitors and Burmese pythons. Further investigation into acetaminophen toxicity in adults of these species is merited. Implications. Although further investigation into adult lethal dosages and strategies to optimize bait deployment while minimizing secondary hazards is required, acetaminophen may have a role to play in the control of these invasive species in Florida.

Presença e distribuição de espécies exóticas na zona de influência de duas trilhas no Parque Nacional da Serra do Cipó - MG

The presence of visitors in national parks is desirable and agrees with their management objectives. However, areas and paths under the influence of visitors are sites with a great possibility of change in the composition of vegetation due to the effects caused by the influence of walking, bicycles and horseback riding. In this work, two trails of the Serra do Cipo National Park were evaluated with the aim of studying and knowing the distribution of native and exotic species in their areas of influence. The theme of biological invasions in protected areas has been an important focus of studies since they represent a threat to biodiversity. The results show differences in the presence of exotic plants and conservation conditions between the two tracks studied.

Bills Favor Mining and Threaten Conservation of Brazilian Merganser (Mergus octosetaceus) at Serra da Canastra National Park, Minas Gerais, Brazil

Serra da Canastra National Park (SCNP) is one of the most important protected areas in the Cerrado biome. Despite its importance to the conservation of rare and endangered species like Brazilian Merganser, two bills were approved in 2010 by Brazil's Chamber of Deputies aiming to reduce SCNP's official boundaries and to transform some of its parts into an Environmental Protection Area (EPA). We evaluated whether such changes would facilitate mining areas to be legally exploited within the park's area, and if those mining areas would represent a threat to Brazilian Merganser populations at SCNP. Results showed that 55% of the mining areas currently within the National Park will be located within the new EPA, and six hydrographic micro-basins inhabited by Brazilian Merganser could be affected by environmental impacts caused by mineral exploitation in those areas. For these reasons, we recommend the two bills be refused at the Federal Senate.
