The use of a geographic information system to increase outdoor tourism

Purpose: Outdoor tourism is a growing segment that still requires data for planning and management. Aimed to present the potential of the Geographic Information System (GIS) to improve outdoor tourism in the North of Portugal. To achieve this purpose, a case study was conducted on developing a Web-GIS in Northern Portugal. Methodology: Four steps were followed to develop the GIS tool with information about outdoor tourism in the North of Portugal. In the first step, municipalities in the North of Portugal sent information about outdoor activities. In the second step, the data were georeferenced and associated. In the last step, a Web-GIS was developed. Findings: The development of tools is an important source of support for tourism. This study identified that a tool such as the GIS could support a destination's decision-making and promotional processes, besides providing detailed information to the tourist and facilitating travel planning. Practical implications: GIS provides effective planning of outdoor tourism, once this tool allows an effective search of the tourist offer and, from the tourist's perspective, relevant suggestions of visits according to their location are presented, facilitating their experience in the region. Originality: Several studies relate to GIS and tourism, but there is still a gap in specific studies on outdoor activities. So, this study presents the importance of GIS to improve outdoor tourism in the North region of Portugal. Understanding this importance is essential in planning and managing tourism, helping further policymaking and marketing strategies.info:eu-repo/semantics/publishedVersio

Avaliação Do Desempenho De Impregnante Inibidor De Corrosão Aplicado Em Estruturas De Concreto Armado Sob A Ação De Íons Cloreto

Existem inúmeros problemas com estruturas de concreto armado, e um dos mais comuns e que apresenta maior risco é a corrosão de armaduras. Sabendo disso, torna-se importante a busca por meios de evitar a corrosão. Diante do exposto, esta pesquisa buscou avaliar a eficiência de um novo material de reparo, aplicado na superfície da estrutura de concreto, quando exposto aos agentes de corrosão. Foram feitos ensaios em pequenos corpos de prova simulando a ação desses agentes, tendo sempre como base outros corpos sem o uso do produto. Após a fase experimental notou-se uma eficiência abaixo do esperado do produto nos diferentes tipos de corpos de prova e com isso concluiu-se que o Inibidor de Corrosão não correspondeu ao esperado sendo pouco eficiente em ambientes marinhos agressivos como o da cidade do Recife

Efeito da adição de glutationa peroxidase e cisteína ao diluidor de congelação do sêmen equino

Foram utilizados ejaculados (n=25) de garanhões para avaliar o efeito de glutationa peroxidase (GPx) e cisteína na viabilidade de espermatozoides congelados. O sêmen foi diluído em Botu Crio, com antioxidantes, e foram formados os grupos: G1, Controle; G2, 1U GPx ; G3, 5U GPx; G4, 0,5mM cisteína; G5, 1mM cisteína. Depois foi envasado em palhetas (0,5mL) e congelado. Após descongelação, 37°C por 30 segundos, alíquotas foram analisadas quanto à integridade de membrana plasmática (IMP) e acrossoma (IAc), potencial de membrana mitocondrial (PMM) e cinética, nos tempos zero (T0) e 60 minutos (T60). GPx 5U e cisteína 0,5mM determinaram maior (P<0,05) IAc em T0 do que em T60. Cisteína 1mM resultou em maior (P<0,05) IAc em T60 do que GPx 1 e 5U e cisteína 0,5mM. O PMM de um garanhão no T60 foi mais alto (P<0,05) do que o de dois garanhões. VCL e VAP foram maiores (P<0,05) no T0 do que no T60 do grupo controle, e um garanhão apresentou, em geral, valores cinéticos mais altos (P<0,05) do que os demais. Conclui-se que a adição de glutationa peroxidase, nas concentrações de 1U e 5U, e de cisteína, nas concentrações de 0,5mM e 1mM, não interferem na integridade de espermatozoides criopreservados de equinos, mas preservam os parâmetros cinéticos de VCL e VAP após 60 minutos de incubação. Ressalta-se, ainda, que o garanhão tem uma forte influência nas características espermáticas pós-congelação

Efeito da adição de glutationa peroxidase e cisteína ao diluidor de congelação do sêmen equino Effect of glutathione peroxidase and cysteine addition in an equine frozen semen medium

Foram utilizados ejaculados (n=25) de garanhões para avaliar o efeito de glutationa peroxidase (GPx) e cisteína na viabilidade de espermatozoides congelados. O sêmen foi diluído em Botu Crio, com antioxidantes, e foram formados os grupos: G1, Controle; G2, 1U GPx ; G3, 5U GPx; G4, 0,5mM cisteína; G5, 1mM cisteína.

Após descongelação, 37°C por 30 segundos, alíquotas foram analisadas quanto à integridade de membrana plasmática (IMP) e acrossoma (IAc), potencial de membrana mitocondrial (PMM) e cinética, nos tempos zero (T0) e 60 minutos (T60). GPx 5U e cisteína 0,5mM determinaram maior (PEjaculates (n=25) of horses were used to assess the effect of glutathione peroxidase (GPx) and cysteine on the viability of frozen sperm cells. Semen was extended at Botu Crio with antioxidants, and divided in groups: G1, control; G2, 1 U GPx; G3, 5U GPx; G4, 0.5mM cysteine and G5, 1mM cysteine, packed in 0.5mL straws, and frozen. After thawing (37° C for 30 seconds) samples were analyzed for plasma membrane (IMP) and acrosome integrity (IAc), mitochondrial membrane potential (MMP) and kinematic, at zero (T0) and 60 minutes after (T60). GPx 5U and cysteine 0.5mM increased (P<0.05) IAc at T0, when compared to T60. Cysteine 1mM resulted in a higher (P<0.05) IAc on T60, than GPx 1 and 5U, and cysteine 0.5mM. The PMM from a stallion on T60 was higher (P<0.05) than those of two stallions. In sperm kinematic, VCL and VAP were higher (P<0.05) at T0 compared to T60 for the control group, and one stallion showed larger (P<0.05) kinematic values than other animals. It is concluded that the addition of glutathione peroxidase at concentrations 1U and 5U, and cysteine, at concentrations of 0.5mM and 1mM, does not interfere with the integrity of cryopreserved equine sperm, but preserves the kinetic parameters VCL and VAP after 60 minutes of incubation. It should be noted also that the stallion has a strong influence on sperm characteristics post-freezing

High resveratrol or quercetin concentrations reduce the oscillation index of frozen goat semen

ABSTRACT The aim of this study was to evaluate the effect of different concentrations of trans-resveratrol or quercetin on the ability of goat sperm to withstand being frozen. Six pools of semen obtained from six male goats were processed with different concentrations of resveratrol or quercetin (Experiment 1: 0, 15, 25, 50, 75 or 100µM resveratrol; Experiment 2: 0, 15, 25, 50, 75 or 100µM quercetin) and frozen. After thawing, the semen was evaluated for sperm kinematics, plasma membrane and acrosome integrity, morphology and oxidative stress following 0 and 1h of incubation. Immediately after thawing (0h), wobble (oscillation index) in the groups treated with 100µM of quercetin or resveratrol was lower (P<0.05) than in those treated with 0 and 25µM resveratrol and 0µM quercetin, respectively. After 1h of incubation, the total motility in treatments with 15, 50 and 75µM quercetin, as well as the plasma membrane integrity in all quercetin concentrations were lower (P<0.05) than at 0h. In opposition, the linearity of semen samples treated with 100µM quercetin and the straightness of those treated with 75 and 100µM quercetin were lower (P<0.05) at 0h than at 1h after thawing. Thus, it can be concluded that resveratrol and quercetin at high concentrations (100µM) transiently reduce the wobble of goat sperm submitted to frozen storage, and that quercetin (75 and 100µM) increases the linearity and straightness over time, which can be favorable for fertility
