This paper aims an epistemologically analysis of the attempt of James Prescott Joule to replace the steam engine by the electric one. In this historical analysis, we use the epistemological categories: style of thinking, collective thinking, intercollective circulation of ideas and practices,Joule and other technicians in Machester received in that time financial incentives from governments and industry to replace the steam engine by the electric one, since it was in Manchester a culture of the technique of the accuracy and precision in which Joule was immersed, which allowed us to initially identify the styles of techniques thinking and experimental efficiency. However, Joule could not replace the steam engine by the electric; and the awareness of the problems faced by him, in the attempt to make such a substitution, led him to seek, through an intercollective circulation of ideas and practices, such as the studies of Faraday and Jacobi, a change of direction in his researches. According to our analysis, what happened was a change of style from a technical to a scientific thinking. In this sense, Joule began to investigate issues of a scientific nature, as the Joule’s effect and the mechanical equivalent of heat, which contributed significantly to the establishment of the principle of conservation of energy. We present here the contributions of this epistemological analysis to the discussion of questions of the nature of science in the basic education and for the training of physics teachers.

In Brazil, the commercial breeding of wild boars (Sus scrofa scrofa) is rapidly expanding. Given the significance of reference values for biochemical analysis for diagnosis of pathological processes and the limitation of data in the literature on this species, Blood samples were collected for determination of biochemical values in 160 wild boars from 180 to 300 days old, clinically healthy farms. The reference range for creatinine was similar to the normal range for swine (1,0 – 2,7mg/dL). There were differences between genders, only for the determination of urea, where the males were higher, although similar to pigs (10 – 30mg/dL). The females, with values from 13.03 to 44.78 mg / dL, do not have statistically significant.

Studies on feeding ecology are important tools for the understanding of feeding strategies and niche dynamics. Information on the type of food consumed, how, and where it is acquired, enable the elucidation of species behavioral, evolutionary and ecological aspects. The diet study based on fecal material enables a low-cost, informative research and avoids the sacrifice of animals. The general aim of this study is to characterize the diet of Euphractus sexcinctus, the yellow-armadillo, based on fecal samples, to contribute with additional information on their feeding habits. The study was undertaken at the Nhumirim ranch, Pantanal da Nhecolândia, MS, during the months of February and March, 2014. The fecal material was collected during the manual capture of the animals and oven dried at 60°C. The food items found in the feces were sorted using a magnifying glass and separated in the following categories: plant matter, invertebrates and soil. Invertebrates were identified to the order level and the plant matter to the lowest taxonomic level possible. Aiming to evaluate the invertebrate availability in the soil, pitfall traps were installed next to the location where individuals were captured, during the months of April and May. We were able to estimate the frequency with which item was consumed during the studied period, and if there is a relationship between the frequency of consumed invertebrates and their availability environment. Among the analyzed samples, we could observe the frequency of occurrence (FO) of plant matter, invertebrates and soil in all the samples. The main invertebrate orders found in the samples were: Coleoptera, Orthoptera and Hymenoptera, with FO of 100%, 100% and 87,5%, respectively. Seeds were found in 100% of the samples. The FO of the Byrsonima orbignyana was high (62,5%), and evidences the potential of the yellow-armadillos as seed dispersers. The use of other techniques, such as the micro-histological...

The James Pinckney Kinard Papers consist of family history charts of the Kinard family and related Kuhn and Summer families, and a Kinard family history, personal correspondence including letters to and from his wife Lee Wicker Kinard (1873-1963), their daughter Nelle Kinard, and other family members, business correspondence, financial papers, literary manuscripts, scrapbooks, and photographs pertaining to Kinard’s student days at the Citadel, his personal and family affairs, his teaching career, his presidency of Winthrop, and his efforts to get his literary manuscripts published. This collection consists primarily of correspondence and offers an informative insight into the personal lives and family affairs of Dr. Kinard and his wife, Mrs. Lee Wicker Kinard. The correspondence generally deals with Dr. Kinard’s struggle against the South Carolina legislature’s cuts in educational appropriations for Winthrop during the Depression; and his varied activities on behalf of Winthrop as President Emeritus. The collection also includes several unpublished manuscripts ranging from his student days at the Citadel to his later life. Areas of research would perhaps include, among others, biographical information on Dr. Kinard and social history during the Depression.

Dragonflies are beautiful animals, important predators in and around aquatic environments, and often good indicators of ecosystem health. Stimulated by digital photography, close-focusing binoculars, and many new regional field guides, the study of dragonflies has exploded in the last ten years. Most importantly, the Internet has connected beginners with experts; observers from everywhere now share their experiences. Here is a book that puts it all on paper.

This paper includes a reassessment of Scrupocellaria reptans (Linnaeus, 1758) (basionym Sertularia reptans), the lectotype of which is selected and figured from among herbarium-sheet specimens held at the Linnean Society of London. Material previously assigned to S. reptans was examined, providing morphological characteristics to distinguish Scrupocellaria ellisi n. sp. Scrupocellaria reptans has a geographically limited distribution in the United Kingdom, while S. ellisi is more widespread in the North Sea, Northeast Atlantic, Adriatic and Tasmania.

The epidemiologic frameworks of zoonosis periodically change in some of its aspects, involving the emergence or reemergence of men and animals' worsening of health. In this scenario, in which rapid changes can happen, the analysis of the prevalence of diseases, as the filariasis diagnosed in dogs from the coastline of Parana, has significant relevance. This study has been carried out with 422 dogs and aimed to determine the prevalence of circulating microfilariae of Acanthocheilonema reconditum, both in animals accommodated at the municipal kennels, as those that live in the district COHAPAR II, both places located in the metropolitan area of the city of Guaratuba-Parana, through two blood tests: evaluation of fresh blood, by the technique of the 'thick drop' and method of Knott modified by Newton and Wright. Thirty of the evaluated animals (7.10%), twenty two males and eight females, showed the presence of microfilariae of A. reconditum as result.

This study evaluated the spatio-temporal distribution, population biology and diet of Menticirrhus americanus in Caraguatatuba Bay. Samples were taken monthly between August 2003 and October 2004, by trawling in two previously selected areas. The northern area is more exposed to wave activity and is influenced by a river, functioning as a small estuary. In contrast, the southern area is relatively sheltered from wave energy and influenced to a lesser degree by smaller rivers. The fishes' length was measured, and the sex and gonadal stage macroscopically identified. The abundance of this species was compared between areas and among months. The diet was identified and quantified. M. americanus occurred in equal proportions in the two study areas, being most abundant in April 2004, followed by December 2003 and January 2004. The population was dominated by small immature individuals. The few individuals in maturation or mature that were captured showed no seasonal pattern of distribution. This species had a varied diet, feeding on worms (nemerteans, sipunculans and echiurans), mollusks (bivalves and cephalopods), polychaetes, crustaceans and fish. The presence of intact nematodes in the intestine suggests that these are parasites. The results demonstrated that M. americanus has a homogeneous spatial and temporal distribution in Caraguatatuba Bay, being uniformly distributed between the south and north areas as well as across the months. This species can be considered a carnivorous predator, showing a preference for consuming benthic sandy-beach species such as glycerids and other polychaetes, crustaceans, and bivalve siphons.
