BIBLIOTECA ESCOLAR E RECICLAGEM NA ESCOLA

A reciclagem visa transformar materiais usados em novos produtos. Devido à situação em que se encontram os recursos naturais e o meio ambiente, a reciclagem tem ganhado cada vez mais espaço juntamente com a educação ambiental, tem-se discutido muito em como é possível fazer reaproveitamentos, e a escola deve ser mediadora entre família, comunidade e educaçãoambiental

Digestibilidade aparente de dietas práticas com diferentes relações energia:proteína em juvenis de pirarucu

The objective of this work was to determine the apparent digestibility of nutrients and energy of diets for pirarucu (Arapaima gigas) juveniles. Eight experimental diets containing four energy:protein ratios (11, 10.1, 9, 8 kcal digestible energy per gram of crude protein) and two non-protein energy sources (soybean oil and poultry fat) were tested in a 4x2 factorial scheme, in triplicates. Two hundred and forty pirarucu juveniles weighting 96.8±2.3 g were distributed in 24 cylindrical-conical fiberglass tanks, adapted for feces collection (modified Guelph system). Fish were fed twice a day to apparent satiation, with experimental diets containing 0.5% of chromium oxide as inert marker in order to determine the apparent digestibility coefficients. Diets containing an energy:protein ratio of 9 kcal digestible energy per gram of crude protein resulted in significantly lower apparent digestibility coefficient for dry matter, crude protein and non-nitrogenous extract. The highest apparent digestibility coefficients for crude fat was obtained with soybean oil. The dietary energy:protein ratio influences the nutrient and energy apparent digestibility coefficients to pirarucu juveniles

Prevalência ultra-sonográfica de litíase biliar em pacientes ambulatoriais

OBJETIVO: Este estudo tem por objetivo determinar a prevalência ultra-sonográfica de litíase biliar em pacientes ambulatoriais. MÉTODO: No período de julho de 2001 a março de 2002, 500 pacientes que procuraram o Hospital Universitário Presidente Dutra e que foram submetidos a exame ultra-sonográfico para doença não biliar foram avaliados. Havia 250 pacientes do sexo masculino e 250 do sexo feminino com idade variando de 19 a 72 anos. RESULTADOS: A prevalência de colelitíase ou de pacientes que haviam sido previamente submetidos à colecistectomia por colelitíase foi de 18,4%. A colelitíase foi mais frequentemente observada naqueles pacientes com idade superior a 60 anos, sexo feminino, multípara e com um índice de massa corporal superior a 30. CONCLUSÕES: A prevalência de colelitíase está aumentada na presença de fatores de risco

Sparrows (Passer domesticus L.) as intermediary hosts of Toxoplasma gondii in poultry farms from the "agreste" region of Pernambuco, Brazil

This paper aimed to identify Toxoplasma gondii infection in house sparrows (Passer domesticus, Linneaus 1758) coming from poultry farms in the "agreste" region of the Brazilian state of Pernambuco. 151 sparrows (Passer domesticus) captured in eight broiler, egg layer and commercial laying poultry farms, were used. Indirect hemagglutination test was used to research anti-T. gondii antibodies. Animals that presented titration of 1:16 were destined to DNA research through Polymerase Chain Reaction (PCR) technique, followed by Nested-PCR. It was observed that, from 151 analyzed samples. 91 (60.3%) were reagents and 60 (39.7%) were not reagents. It was verified, through analysis of the distribution of infected animals frequency per farm, that in only one farm (12.5%) no animal reagent to T. gondii was captured. It was also observed that three (30.00%) of the ten samples destined to DNA research for T. gondii were positive to PCR and four (40.00%) were positive to Nested-PCR. Anti-T gondii antibodies occurrence and the molecular identification of the agent confirmed natural T. gondii infection in sparrows from poultry farms in Brazil. Other studies must be carried out to highlight the real importance of these animals in the epidemiological chain and their efficiency in the transmission of the parasite to felines. Therefore, researches that use parasite isolation and molecular techniques to determine genomic profile of the agent present in these poultry farms are needed

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
