In this work, the "yield potential" is proposed as a new methodology to relate production with quality, which allows us to achieve the optimal bearing status of the tree for each orchard and season. The "yield potential" is defined as the maximum production that can be obtained in each orchard ecosystem as a function of a commercial and qualitative target such as fruit size or sugar content. The presented methodology is based on the differentiation of the bearing status of the trees by hand thinning, and grouping them, after harvest, according to the number of fruits per tree for nonlinear regression analysis. Estimating thinning needs or effectiveness to obtain the desired commercial fruit size and relating average fruit weight per tree with commercial fruit size are the most important achievements of this methodology.
A planta aromática e medicinal Origanum vulgare pertence à família Lamiaceae. Esta erva aromática é vulgarmente chamada de orégão vulgar ou manjerona selvagem e são utilizadas várias partes da sua estrutura física para diversos fins, pois os seus metabolitos secundários conferem-lhe algumas propriedades tanto condimentares como medicinais. Trata-se de um artigo de revisão abordando diversos aspetos das possíveis utilizações desta planta espontânea no nosso país.
This study‘s objective was to determine which lifestyle variables have a direct relationship with motivation towards the practice of physical activity. There was a sample of 858 subjects, aged between 18 and 77 years (41.62 ± 13.30), from different parts of Spain. The instruments used for data collection were the Behavioural Regulation Exercise Questionnaire, for Intrinsic Motivation measurement; the Intentionality to be Physically Active Measurement Scale, for the intention of future practice measurement; and the Healthy Lifestyles Questionnaire, for tobacco consumption, rest, balanced diet and respect for meal schedule variables measurement. The results determined that the Intention to be Physically Active variable was significant as a predictor of Intrinsic Motivation towards sport whereas the variables Rest Habits, Tobacco Consumption, Balanced Diet and Respect for Meals Schedule were not significant. The importance of promoting strategies for increasing intrinsic motivation is emphasized.
The present paper describes the development of an application in a Computer Engineering course using open source software tools. The main goal is the implementation of an educational system to improve the interface between students and teachers, as well as to serve as a mean of communication and events spreading related to computing to all members of the academic community where it is installed. In a first stage the system was built and implemented in one educational Institution but it is now improved based on the collaboration of teaching staff, of other Portuguese Engineering Department, allied to computer Engineering students skills and motivation. The architecture, main features, results and future work of the developed system are reported through the sections of this paper.
To provide the best training in software engineering, several approaches and strategies are carried out. Some of them are more theoretical, learned through books and manuals, while others have a practical focus and often done in collaboration with companies. In this paper, we share an approach based on a balanced mix to foster the assimilation of knowledge, the approximation with what is done in software companies and student motivation. Two questionnaires were also carried out, one involving students, who had successfully completed the subject in past academic years (some had already graduated, and others are still students), and other questionnaire involving companies, in the field of software development, which employ students from our school. The analysis of the perspectives of the different stakeholders allows an overall and holistic) view, and a general understanding, of the effectiveness of the software engineering teaching approach. We analyse the results of the questionnaires and share some of the experiences and lessons learned.
This paper proposes a simple scheme for audio
coding that does not use perceptual models. The audio coder
is based on the discrete wavelet transform to decorrelate
signals, computed through the lifting scheme, and followed by
Huffman coding. The evaluation of the coding scheme is
presented by using some .wav audio test files, coded for
different conditions, and also includes subjective evaluation.
Experimental results show the compression ratios achieved,
the degradation of the signals expressed as values of signal to
noise ratio and the changes in spectrum information.
The accelerated evolution of information technologies and their impact on society in general have in effect motivated special attention within the scope of the educational system. This paper presents the state of the art in what concerns to the Portuguese national projects on ICT. A chronological presentation of the several projects, emphasizing their main objectives, activities, problems and outcomes will be discussed. The main of this paper is paper is also to reflect on the consequences of those national projects regarding their impact in the process of teaching and learning within the Portuguese educational system.
The concept of land units refers to coherent spatial areas that are characterized by a certain degree of homogeneity concerning certain properties like geology, soils and climate. The Land use mosaic corresponds to a circumstantial layer that represents the present state of the landscape depicting the present factors of resource allocation. Nevertheless, the stable potential layer is related with the stable characteristics of each site and allows the identification of use constraints or potentials. In this study we use a methodology based in the land unit concept to define a stable potential layer at a regional level. Therefore, 26 land units were delimited for the Beira Baixa region. Those units resulted from the combination of geomorphology, soil parent material and bioclimatic influence. For each land unit representative samples were characterized in terms of its land use mosaic attributes. For that purpose, selected landscape metrics were calculated, quantifying the land use mosaic geometrical characteristics, namely: Shannon’s Diversity Index, Edge Density, Mean Patch Size and Number of Patches. The existing land use types were also quantified. Finally, a cluster analysis was performed to define groups of samples representing the land units that have the similar land use mosaic types. The validation of the previously defined land units confirmed the reliability of the proposed methodology, with most of the land units strongly influencing the land use mosaic. This relationship is stronger in the land units that occupy a higher extension in the region, mainly soils rich or very rich in silica under the influence of a mesomediterranean subhumid bioclimate.
Pollen contamination is a serious problem in seed orchards, which may reduce genetic gain considerably. High levels of pollen contamination can be reached even when the stands are isolated by several hundred of meters from natural populations. Recently, molecular markers have been used to trace details of reproductive processes. The efficiency and utility of estimating mating system, gene flow and pollen contamination are greatly increased by using microsatellite markers, which are ideal for parentage studies and fingerprinting, due to their high discrimination power. The aim of the present study was to estimate the pollen contamination in a clonal seed orchard (CSO). Three nuclear microsatellites were used to screen the 60 different clones from the CSO and the 206 seeds collected from 7 trees from each one of the three plots distributed according to the main winds direction. The 3 loci distinguished the 60 clones genotypes, but 2 pairs. Minimum and maximum estimates of pollen contamination were 46% and 56%, respectively. Those values could be explained by the presence of a P. pinaster stand at a distance lower than 2 Km and the existence of natural regeneration of this species on the orchard’s isolation zone. External plots pollen contamination was higher than in the inner plot. Only 20% of the clones contributed for the next generation, which may lead to a reduction of seeds’ genetic variability. However, an asymmetrical sampling from the orchard (3 plots) was made, which might have biased the results, and the effective number of clones participating in the next generation might be higher. The outcross pollination rate was found to be very high - 90.2%. The minimum estimate of biparental inbreeding was 21.2%, a not so high value if we consider the number of seeds sampled and the orchard size.

The CienTIC Project aims to enhance the work and activities as a consequence of the Internet National Programme for Primary Schools that were created by the Portuguese Ministry of Education on the schooling year of 2002/03 till June 2004. Within this programme the main aim was the creation of a website in each Portuguese primary school besides the improvement and use of Internet by pupils and teachers. The focus of the CienTIC project is to promote an effective use of the school’s website and the use of Internet as a resource that promotes different ways to teach and learning science. The involvement of student teachers is considered important in order to ensure that future use of the Internet resources has more probability to be used in educational context mainly in a country with a lack of systematic use of digital resources.
A significant industrial development, associated with a demographic
expansion, occurred during the last decades of the XX century, in Loures valley, a region
located in the vicinities of Lisbon, the capital city of Portugal. This was accompanied
with an important modification of land use and occupation patterns, mainly the decrease
of the agricultural land.
One of the main consequences was the deterioration of the groundwater chemistry
observed in the shallow aquifer associated to Trancão river, a subsidiary of Tagus river.
Factorial Correspondence Analysis has been used to build a water quality index, for
evaluating the impact of the anthropogenic factors on groundwater of the shallow aquifer.
By analysing the kriged maps of the values of the index, it was possible to identify the
areas more sensitive to the anthropogenic impact.
This paper presents a comparative study on image coders using the discrete cosine transform and the discrete wavelet transform, addressing in particular the JPEG-like and the EZW based image coders. We compare and evaluate the JPEG Baseline Image coder (using the DCT), a JPEG-like image coder based on the DWT, and an EZW coder, which is also based on the DWT. Taking into account the differences on the architecture of the coders, we compare them by using the same test images, for approximately the same conditions and characteristics, namely the approximately equal compression ratio.

A novel teaching strategy is described, which was developed to introduce the key notion of chemical elements to 15-year-old Portuguese chemistry pupils. The strategy started from the analysis of the so-called ‘Lavoisier law ’and explored the relationships between macro and micro level chemistry in an innovative way. The key idea was first to explore the macro level (mass conservation) to help pupils consider the existence of indestructible units (elements, micro level) as a logical necessity for making sense of experimentally observed phenomena. The approach facilitates the integration of content and process aims.
Since the nineties, a lot has been written about local sustainability, mostly about big cities and/or big regions. These days the debate about small towns and/or rural municipalites has also come about. It is up to all the agents, political and from the community, as well as to the citizens to promote the transformation to more sustainable societies. It is therefore urgent the development of tools like the Indicator System (IS) at a local level, having in mind the involvement of all the agents, that will allow us to evaluate whether we are near or far from that transformation. The incorporation of sustainability criteria and its measurement, having in mind the singular characteristics of these municipalities, will allow us to know and evaluate the Sustainable Development (SD) at a local level, to increase the sensibility of the agents about environmental issues and to promote change in the community. For that to happen the population’s involvement is essential for it allows the strengthening of the commitment for SD. The case study presented is about the Beira Baixa region in the interior of Portugal, its population represent 0.8% of the resident population of Portugal. That translates as one of the lowest populational densities. The main objective of this study is to present the results of the questionnaire applied to a representative sample of the resident population of Beira Baixa, Portugal, over 18 years of age. The general aim of the questionnaire was to inquire the population awareness about sustainability concepts and IS and self-assessment of the local sustainability. The results allow us to verify that a large majority of the participants has hear the term SD, the media being the largest contributor to this and that the promotion of the SD is our own responsibility. In terms of the SD dimensions, it is the environmental and economical ones the most important, in contrast with the social and governance/institutional. About half of the participants considers that their quality of life “stayed the same”, but a quarter of them considers that it is “worse”. When asked about IS, less than half of the participants had ever heard about IS for SD, and the ones that had, heard it mostly through the media. These participants consider that the selection of the indicators should factor the citizens’ opinion, but little more than half of the participants would like to participate in that selection. It is important a wide spread of SD and of the IS among the population, because there is a clear imbalance between the economic and environmental dimension and the social and governance/institutional dimensions.
Las lesiones de la musculatura isquiosural son las más comunes en fútbol, y pueden presentar efectos residuales que cambien el patrón de un gesto técnico. El presente estudio analizó las diferencias en la técnica de golpeo entre jugadores anteriormente lesionados y jugadores no lesionados, así como las correlaciones entre la capacidad psicológica para retornar a la práctica y las características del gesto. Tres futbolistas que habían padecido una lesión de isquiosurales conformaron el grupo de jugadores anteriormente lesionados, y tres futbolistas que no habían padecido ninguna lesión en el miembro inferior en los últimos dos años, formaron el grupo de jugadores no lesionados. Se analizaron los gestos de golpeo a balón parado y de golpeo en carrera a través del programa Kinovea. Asimismo, se evaluó la capacidad psicológica para retornar a la práctica mediante el Injury Psychological Readiness to Return to Sport (I-PRRS). Únicamente la velocidad del balón en el golpeo en carrera presentó diferencias significativas entre grupos (p<0,05). Además, se obtuvieron correlaciones positivas entre la preparación psicológica para retornar y la flexión de rodilla en el golpeo en carrera, y entre la flexión de rodilla en el golpeo a balón parado y los ítems 3 y 4 del I-PRRS. Asimismo, se hallaron correlaciones negativas entre la extensión de cadera en el golpeo a balón parado y el ítem 6 del I-PRRS. Los resultados permiten concluir que variables cinemáticas y variables psicológicas se encuentran interrelacionadas tras una lesión en la musculatura isquiosural.
Abstract
The entrepreneurial university is seen as an important catalyst for regional economic and social development, particularly because it generates and exploits knowledge as entrepreneurial opportunities. This paper aims to analyze the challenges Smart Specialization Strategies (S3) imply to the role entrepreneurial universities can play in regional development. The former has increasingly gained space as a new competitive paradigm and universities can be of great importance for its successful implementation because of their contribution both as a partner institution, policy actor and producer of knowledge and social capital that can affect the potential territorial competitiveness and sustainability. By adopting institutional economics, resource-based view, and endogenous growth approaches, this study aims to provide a wider understanding of the socioeconomic impacts of the entrepreneurial universities on their regions The paper critically addresses this knowledge gap, focusing on policy, organization, and the role of individual actors to uncover the challenges facing higher education institutions as they seek to engage with their regions and promote territorial competitiveness and sustainability. As higher education institutions begin to ramp up their technology transfer activities and start to commercialize their research, it is crucial to consider the regional context and the regional impacts that this can have. In this context, and as a final point, the concept of entrepreneurial ecosystem is reinterpreted as a possible path of the dynamics resulting from S3 and entrepreneurial universities interactions, opening the way for a set of public policy recommendations.
Considering the objectives of the Erasmus+ Domotic School Garden are, among others, the
increase in motivation and academic performance in sciences and technology, this manuscript
summarizes the use of some sensors to monitoring and evaluating the hydrology and water quality, in a
small agro-forestry basin, under Mediterranean climatic conditions. For this porpuse it was used a
multiparameter probe, with sensors of electrical conductivity, temperature, nitrates and turbidity in the
return flows of the study basin. It was instaled as well a flume, as a hydraulic structure, and a ultrasonic
sensor to evaluate the discharge at the outlet of the basin. With a small description of each sensor, the
text is enriched with an example of results for each one, to perceive the kind of information is given to
the researcher. For these summarized results, it´s possible the importance to understand the hydrologic
beahvior and the dynamic of the pollutants in the basins, necessary to take measuments to prevent and
mitigate the pollution of water bodies.
Straddling the frontiers of two neighboring countries around the Tagus River, Portugal and Spain, the Tejo Internacional Natural Park extends over an area of 26,484 hectares in the district of Castelo Branco, Portugal.
The pilot project for collaborative management of the Natural Park of Tejo Internacional, beginning in 2017, is an initiative of the Portuguese Ministry of Environment and Energy Transition, which consists on a participatory and collaborative form of management of a protected area, involving the three municipalities of the area (Castelo Branco, Idanha-a-Nova and Vila Velha de Ródão), ICNF, Quercus, the Polytechnic Institute of Castelo Branco and the Business Association of Beira Baixa, with a total of seven partners. To monitor the new governance model effects on land use and on biodiversity, is important to identify the relation between land management options and the state of the environment indicators. In this study we analyze the past trends and the current state of the Natural Park of Tejo Internacional in terms of protected species and habitats, and we propose a set of indicators to monitor the possible impact of governance change in the natural values.
The interaction between Art and Branding has occurred in various contexts, for reputation purposes, through all communication media, for the purposes of persuasion, promotion, symbolism or secondary associations, impacting on social and cognitive levels. The scope of this article is to correlate Branding Art and Art Infusion with the spirit of the place, concretely to present a conceptual model which correlates artistic activities developed in a neighborhood with Branding Art and Art Infusion concepts taking into account the reinforcement of the current place brand strategy. The article is based on the literature review and in explanatory Case Study, using results from the project “Re-Habitar el Barrio: Procesos de Transformación y Empoderamiento entre Universidad-Escuela-Sociedad a través de Prácticas Artísticas”. The use of the schemes makes possible to visualize and share abstract concepts and value data in a participatory group way, detecting the best ways to facilitate communication and mediate interaction between people and territory. The results consist of defining a brand argument and defining its conceptual model, making use of the schematics as a way of visualizing abstract concepts.

A collection of data has been carried on the Merino Beira Baixa sheep at the Escola Superior Agrária (Agriculture School)in Castelo Branco (ESACB)in Portugal from 1981 to 1987. According to the birth type of females (single of double), their average age at the time of first lambing amounted to 600,10 ± 158,86 days and to 583,90 ± 159,78 days.Differences were not significant. However this parameter was influenced by the "year" factor (P<0,01). It was shown that the intervals between lambings (I.P.) did not depend on the parturition months inside the seasons, but depended on parturition months between the two parturition seasons (from January to March 296,4 ± 64,22 days and from September to November 380,0 ± 71,5 days). The "I.P." revealed significant differences (P<0,01) in terms of the conception age. The average apparent fertility rate amounted to 86,6%, the prolificacy to 114,2% and the average numerical productivity to 92,7%. All these rates were influenced by the ewes age at lambing. Analysis were carried on further reproductive parameters.
Wireless sensor networks can be composed of thousands of smart sensing nodes that capture environment data in a cost-efficient way. Such networks present new challenges when compared to traditional computer networks, namely in terms of smart node processing power and very limited energy resources. Ubiquitous computing can benefit from wireless sensor networks, from the perspective that sensed data can be used on behalf of the user without explicit intervention, turning ubiquitous computing into a reality. For the data to be available everywhere wireless sensor networks must be connected to the Internet. Two main approaches can be considered: proxy-based or sensor node stack based. This second approach turns sensors into data producing hosts, also know as ”The Internet of Things”. For years the TCP/IP protocol suite was considered inappropriate for wireless sensor networks, mainly due to the inherent complexity and protocol overhead for such limited hardware. However, recent studies made connecting wireless sensor to the Internet possible for integration on the future Internet. This paper surveys the current state-of-the-art on the connection of wireless sensor networks to the Internet, presents related achievements, and provides insights on how to develop Internet Protocol-based communication solutions for wireless sensor networks today.
In the last years, entrepreneurship education has increased in importance and presence on the curriculums of different degrees and domains, and is gaining the attention of higher education institutions as well as secondary schools and training centers.
Although the mainstream focus of entrepreneurship is new business creation, it can be argued that there can be a wider application, namely in intrapreneurship and social entrepreneurship, typical subfields of study in the entrepreneurship realm.
This vast possibility requires that education institutions strategically choose the focus of their approach regarding entrepreneurship education but they can also propose a curriculum that encompasses all this. Also, this option will enable students to obtain the tools that will allow them to build their path.
The present paper aims to reflect on the choices made at entrepreneurship courses that are taught at non-business schools in higher education institutions. An issue regarding the prevailing business orientation is that non-business students can feel excluded or not attracted towards entrepreneurial education and its importance because it’s not their work field.
Finally, based on several years of experience in teaching entrepreneurship, we discuss some problems that are experienced.
Crack closure concept has been widely used to explain different issues of fatigue crack propagation. However, different authors
have questioned the relevance of crack closure and have proposed alternative concepts. The main objective here is to check
the effectiveness of crack closure concept by linking the contact of crack flanks with non-linear crack tip parameters.
Accordingly, 3D-FE numerical models with and without contact were developed for a wide range of loading scenarios and the
crack tip parameters usually linked to fatigue crack growth, namely range of cyclic plastic strain, crack tip opening
displacement, size of reversed plastic zone and total plastic dissipation per cycle, were investigated. It was demonstrated that:
i) LEFM concepts are applicable to the problem under study; ii) the crack closure phenomenon has a great influence on crack
tip parameters decreasing their values; iii) the ΔKeff concept is able to explain the variations of crack tip parameters produced
by the contact of crack flanks; iv) the analysis of remote compliance is the best numerical parameter to quantify the crack
opening level; v) without contact there is no effect of stress ratio on crack tip parameters. Therefore it is proved that the crack
closure concept is valid.

The aim of the study was to know the level of development of algebraic thinking in Higher Education students. During the investigation, we wanted to measure the success rate in the size of the next generalization and the dimension of distant generalization and measure the degree of difficulty in the various proposed patterns. In the context of the training of future primary teachers and childhood educators, an activity was developed in the context of the curricular unit of mathematical recreation with 15 students. The theme of algebraic thinking assumes current relevance because according to [1], it has become a cross-cutting theme of the curriculum. In order to know the level of algebraic thinking, 4 tasks with repetition patterns were proposed from elements of the manipulable material: pattern blocks. The tasks were presented through Kahoot, an applet that allows, according to [2] and [3] to increase motivation, to improve concentration, to promote reasoning, to allow collaborative work, to reverse roles between student and teacher, use ICT in the classroom and evaluate in real time.
Repeat patterns were proposed from the simplest to the most complex (ABAB, ABBABB, ABCABC, ABCCABCC). For this proposal, we have considered Vitz and Todd [4], who present a model of repetition pattern classification. In each task we proposed 2 questions that involved near generalization (10th term and 15th term) and 2 distant generalization questions (35th term and 100th term). In methodological terms the teacher projected each pattern and its questions on the projection screen so that all students could visualize, and each student responded individually using their mobile phone, tablet, or laptop computer. For each question, the students had a resolution time of 90 seconds. In none of the questions has the student's resolutions been exhausted. The results allowed to verify that of the 16 questions proposed, there was a percentage of correctness in the 71,67% (average of the questions). Regarding the near generalization, we obtained a percentage of success in the order of 70%. On the other hand, in relation to the distant generalization, we obtained a percentage of success in the order of 73,33%. We also observed that students showed greater ease in the ABBABB pattern, with a success rate of 80% and greater difficulty in ABAB with a success rate of 56.67%. Regarding the ABCABC pattern, we obtained a success rate of 75% and a success rate for the ABCCABCC pattern.
