Preliminary attempt to develop a path-flow analysis model for swimming performance in children

The aim of this research was to develop a path-flow analysis model from age-group swimmer’s performance based on biomechanical and energetic parameters. Twenty two young male age-group swimmers with several competitive levels volunteered to serve as subjects. It was assessed swim velocity, stroke length, stroke frequency, stroke index, propulsive efficiency, critical velocity and 200 m freestyle event performance. To verify the quality of the model, root mean square residuals (RMSR) was computed. The confirmatory model explained 54% of swimming performance. RMSR was 0.064. As a conclusion, the model based in biomechanical and energetic variables, according to the relationships suggested is appropriated to explain performance in age-group swimmers

Exercise Training On Cardiovascular Diseases: Role Of Animal Models In The Elucidation Of The Mechanisms

Cardiovascular diseases, which include hypertension, coronary artery disease/myocardial infarction and heart failure, are one of the major causes of disability and death worldwide. On the other hand, physical exercise acts in the prevention and treatment of these conditions. In fact, several experiments performed in human beings have demonstrated the efficiency of physical exercise to alter clinical signals observed in these diseases, such as high blood pressure and exercise intolerance. However, even if human studies demonstrated the clinical efficiency of physical exercise, most extensive mechanisms responsible for this phenomenon still have to be elucidated. In this sense, studies using animal models seem to be a good option to demonstrate such mechanisms. Therefore, the aims of the present study are describing the main pathophysiological characteristics of the animal models used in the study of cardiovascular diseases, as well as the main mechanisms associated with the benefits of physical exercise.2

Preliminary attempt to develop a path-flow analysis model for swimming performance in children

The goal of competitive swimming is to travel the event distance as fast as possible. The identification of the parameters that predict swimming performances is one of the main aims of the swimming “science” community. Indeed, it is consensual that biomechanical and energetic variables are determinant for performance in this sport. Several research groups dedicate their attention to the relationships establish between biomechanical and energetic variables on adult swimmers, with special emphasis on elite adult swimmers

Effect of modified atmosphere on polyphenols during storage of pasteurised strawberry purees

The minimum loss of processed fruit nutritional quality must been guaranteed during storage and the atmosphere can be a limiting step. Strawberry pur ees flushed with gas mixtures: 10 kPa O2 þ 90 kPa N2, 100 kPa N2 and air (78 kPa N2 þ 21 kPa O2 þ 0.03 kPa CO2) were stored for 90 days at 4 and 23 C and revealed no effect in total antioxidant activity and in total phenolic content. The compounds (þ)-catechin, ( )-epicatechin and quercetin-3-rutinoside were not affected by the atmospheres for both temperatures and ellagic acid was the exception within strawberry phytochemicals, where its concentration was higher for samples stored in air. Total anthocyanin content was better preserved when strawberry pur ee was stored in 100 kPa N2 at 4 and 23 C, at which temperatures their levels decreased 24 and 77%, respectively. At 4 C cyanidin-3- glucoside presented no significant differences between atmospheres. Pelargonidin-3-glucoside and pelargonidin-3-rutinoside decreased both 27% for 100 kPa N2 and 45% for 10 kPa O2 and air. All the individual anthocyanins were not affected by the atmospheres when stored at 23 ºC.info:eu-repo/semantics/publishedVersio

Seropositivity of Coxiella burnetii in wild boar (Sus scrofa) and red deer (Cervus elaphus) in Portugal

Coxiella burnetii is a zoonotic microorganism that infects a wide range of wild and domestic species, causing the disease Q fever, frequently involving ticks as vectors. To better understand the occurrence of C. burnetii infection in wild boar (Sus scrofa) and red deer (Cervus elaphus), an epidemiological study was conducted in the Centre region of Portugal.info:eu-repo/semantics/publishedVersio

Efeito do ensacamento dos frutos no controle de pragas e doenças e na qualidade e maturação de maçãs ‘Fuji Suprema’.

O objetivo deste trabalho foi avaliar a eficiência de embalagens de diferentes materiais para a proteção contra pragas e doenças e seu efeito sobre a qualidade físico-química, maturação e teor de cálcio (Ca) em maçãs ‘Fuji Suprema’. O experimento foi desenvolvido nas safras de 2007/2008 e 2008/2009, em pomar manejado sob o sistema orgânico, localizado na região de São Joaquim (SC). O pomar era composto por plantas de dez anos de idade da cultivar Fuji Suprema, sobre porta-enxerto ‘Marubakaido’, com interenxerto ‘EM-9’. Depois do raleio manual, aproximadamente 40 dias após a plena floração, os frutos foram ensacados com embalagens plásticas transparentes microperfuradas ou de tecido não texturizado (TNT). Os frutos foram mantidos ensacados até a colheita. A testemunha foi constituída por frutos não ensacados. Na colheita, os frutos foram avaliados quanto aos danos provocados por mosca-das-frutas (Anastrepha fraterculus), mariposa oriental (Grapholita molesta) e lagarta enroladeira (Bonagota salubricola). As doenças foram avaliadas pela incidência de sarna da macieira (Venturia inaequalis), podridão amarga (Colletotrichum gloeosporioides) e podridão carpelar (Alternaria sp., Fusarium sp.). Também foi avaliada a incidência de distúrbios fisiológicos “russeting” e “bitter pit”, atributos físico-químicos de maturação e qualidade e o teor de Ca nos frutos. Independentemente do tipo de embalagem verificou-se que o ensacamento é prática eficaz na proteção contra o ataque de insetos, mas não reduz a incidência e o desenvolvimento de doenças nos frutos. Na safra de 2008/2009, o ensacamento dos frutos aumentou o teor de Ca e reduziu a incidência de “bitter pit”, e aumentou a incidência do “russeting”. O ensacamento dos frutos antecipou a maturação, especialmente com embalagem plástica transparente microperfurada, e reduziu a coloração vermelha, especialmente com embalagem TNT

Selecting ecosystem indicators for fisheries targeting highly migratory species: An EU project to advance the operationalization of the EAFM in ICCAT and IOTC

Several international legal agreements and guidelines have set the minimum standards and key principles to guide the implementation of an ecosystem approach to fisheries management (EAFM). However, the implementation of an EAFM in tuna Regional Fisheries Management Organizations (RFMOs) has been patchy and lack a long-term plan, vision and guidance on how to operationalize it. The Specific Contract N0 2 “selecting ecosystem indicators for fisheries targeting highly migratory species-” (SC02 project) under the Framework Contract - EASME/ EMFF/2016/008 provisions of Scientific Advice for Fisheries Beyond EU Waters- addresses several scientific challenges and provides insights to support the implementation of an EAFM through collaboration and consultation with the International Commission for the Conservation of Atlantic Tunas (ICCAT) and the Indian Ocean Tuna Commission (IOTC). Specifically, this project first highlights properties of success and best practices from other regions of the world in operationalizing the ecosystem approach that potentially could be transferred to ICCAT and IOTC. Second, it delivered a list of potential ecosystem indicators of relevance to tuna RFMOs (ICCAT and IOTC) that are suitable to track the impacts of fisheries targeting tuna and tuna-like species on the broader pelagic ecosystem. Third, it designed a general framework based on a rule-based decision tree to provide guidance on how reference points could be set and used for diverse types of ecosystem indicators. Fourth, it proposed candidate ecoregions within the Atlantic and Indian Oceans which could be used to guide region-based ecosystem plans, assessments and research to ultimately provide better ecosystem-based advice to inform fisheries management. Fifth, it developed two pilot ecosystem plans for two case study regions, the tropical ecoregion within the ICCAT convention area, and the temperate ecoregion within the IOTC convention area. At this stage, these pilot ecosystem plans aim to create awareness about the need for ecosystem planning, start a discussion about the elements that need to be part of a planning process, and initiate a discussion in ICCAT and IOTC about the potential needs of ecosystem plans and their function. Finally, this project provided recommendations to foster the potential development, use, and implementation of ecosystem plans in ICCAT and IOTC
