Comparison of soil pH measurement in a non tilled vineyard: conventional labora...
Marques da Silva, JR; Terrón, JM; Blanco, J; Pérez, F; Galea, F; Moral, FJ; Alexandre, C; Serrano, J; Silva, LLThis work pretends to compare the soil pH measured by the 3100 Veris sensor with the conventional soil sampling in a specific soil condition of a non tilled vineyard. Whereas high density data was obtained with the soil pH sensor, which were used to delineate a pH surface using a geostatistical algorithm, conventional laboratory values were divided in two sets, depending on their location in a 3 or a 12 years n...
Otoczenie zewnetrzne efektywnosci energetycznej w rolnictwie – studium przypadk...
Golaszewski, J; de Visser, C; Lutsyuk, C; Stolarski, M; Brodzinski, Z; Olba-Ziety, E; Myhan, R; Mikkola, H; Ahokas, J; Jokiniemi, T; Rajaniemi, MUntil recently energy efficiency in agriculture has received little attention. Nevertheless, energy consumption in agriculture is considerable, especially when indirect energy use is taken into account. AGREE has the objective of showing the potential of short term energy efficiency gains and the promise of a long term potential. Environmental effects of savings on direct and indirect energy use in agriculture ...
Dzialania energooszczedne w rolnictwie (Energy saving measures in agriculture)
Golaszewski, J; de Visser, C; Stolarski, M; Brodzinski, Z; Olba-Ziety, E; Myhan, R; Mikkola, H; Ahokas, J; Jokiniemi, T; Rajaniemi, M; Meyer-Aurich, AThe reduction of energy inputs in agricultural production is a process of practical implementation of a set of energy saving (ES) measures associated with a given type of production, farm infrastructure and managerial or organizational activities. In six national reports from Finland, Germany, Greece, the Netherlands, Poland and Portugal for 13 subsectors of agriculture, 481 ES measures in total were identified...

Utilização da equação de Hargreaves Samani para o cálculo da ETo em estufas
Shahidian, S.; Serralheiro, R.P.; Teixeira, J.L.; Serrano, J.; Santos, F.L.; Guimarães, R.C.Poster ; A equação de Hargreaves Samani, HS, tem sido utilizada com sucesso para o cálculo da Evapotranspiração, Eto, ao ar livre. Os resultados indicam uma boa correlação entre a Eto obtida por este método e a obtida pelo método de Penman-Monteith, PM, que exige um conjunto maior de parâmetros. Até a data pouco se sabe sobre a aplicabilidade da equação de HS em agricultura protegida. Neste ensaio foram instal...
Learning roadmaps for Higher Education
Oliveira, Miguel; Serrano, J. Artur; Duarte, A. Manuel de OliveiraAn integrated platform for the support of teaching activities as been developed and deployed at the Aveiro Norte Polytechnic School of the University of Aveiro. In this paper we present an approach to Learning Roadmaps for Higher Education based on this platform. The aprend.e platform – Electronic Integrated System for Learning and Training - has at its core a Learning Management System with a number of plugins...
Nocardia otitidiscaviarum (GAM-5) induces parkinsonian-like alterations in mouse
Díaz-Corrales,F.J.; Colasante,C.; Contreras,Q.; Puig,M.; Serrano,J.A.; Hernández,L.; Beaman,B.L.Parkinson's disease, a major neurodegenerative disorder in humans whose etiology is unknown, may be associated with some environmental factors. Nocardia otitidiscaviarum (GAM-5) isolated from a patient with an actinomycetoma produced signs similar to Parkinson's disease following iv injection into NMRI mice. NMRI mice were infected intravenously with a non-lethal dose of 5 x 10(6) colony forming units of N. oti...
Is Merino wool disappearing in Portugal? Merino da Beira Baixa case
Rodrigues, J.P.V.; Andrade, L.P.; Serrano, J.In Portugal, we are facing a fast decrease in the production of good quality wool. This situation can be seen from a qualitative and quantitative point of view by looking at the most extreme situation, which involves almost the extinction of a Merino breed – Merino Beira Baixa (MBB) – due to its inability to produce high milk quantities when subjected to the better handling of the more intensive productions sys...
Cardioselective and cumulative oxidation of mitochondrial DNA following subchro...
Serrano, J.; Palmeira, C. M.; Kuehl, D. W.; Wallace, K. B.We recently reported the preferential accumulation of 8-hydroxydeoxyguanosine (8OHdG) adducts in cardiac mitochondrial DNA (mtDNA) following acute intoxication of rats with doxorubicin (C.M. Palmeira et al., Biochim. Biophys. Acta, 1321 (1997) 101-106). The concentration of 8OHdG adducts decreased to control values within 2 weeks. Since conventional antineoplastic therapy entails repeated administration of smal...
Fine wool quality in Portugal (preliminary results)
Andrade, L.P.; Rodrigues, J.P.V.; Serrano, J.The objectives of this work are, from one side, to verify the quality of fine wool produced in Portugal, taking as the basis for the evaluation the fineness and, in the other side, to identify the existent correlation between the tactile classification and the laboratory evaluation.
