Building Efficiency Adopting Ecological Materials and Bio Architecture Techniques
Get PDFObjective. There are many measures that individual consumers, families, companies, contractors, real estate developers, household owners and governments can take to promote post-carbon cities. Thermal insulation is definitely one of the most important investment to make in order to achieve these future goals. Method and solutions Insulation can be carried out by using ecological cork panels. Cork is a natural and renewable material, which in itself, is the result of a CO2 sequestration, and it can also store C. Therefore it can effectively contribute to the design of the Post-Carbon City by reducing energy waste, improving the quality and the insulation of buildings.The expansion of the area occupied by the cork oak forests would permanently increase the absorption and sequestration of carbon. Forest policy guidelines must aim at the restoration of the existing cork oak forests, as well as the rehabilitation of cork oak forests destroyed by man. This will increase and strengthen the contribution made by forest resources to the construction of the Post Carbon City.Outcomes and benefits Some benefits of such policy are as follows: the sequestration of CO2 eliminated from the atmosphere (creating carbon credits), because it is used for the growth of trees and the creation of cork bark; the availability of cork planks which are the raw material for bio-building; the positive consequences of using cork panels and granules in Bio Green Buildings, such as energy saving for heating and cooling and the consequent reduction of CO2 emissions. Risparmio energetico negli edifici mediante adozione di eco materiali e tecniche di Bio EdiliziaObiettivo.

Può quindi efficacemente contribuire a realizzare concretamente la Post Carbon City migliorando l’ isolamento e la qualità degli edifici ed eliminando lo spreco di energia. Ampliare le aree occupate da sugherete aumenta in modo permanente l’assorbimento e la eliminazione definitivo ovvero il sequestro della CO2 . Per questa ragione la policy urbana può essere integrata con la policy ambientale e forestale, propugnando il restauro delle sugherete esistenti e il re impianto di quelle compromesse dall’azione antropica.

A reinvenção dos jardins xerófilos no Algarve com recurso às suculentas xeromórficas
Get PDFConsiderando a atual conjuntura climática, é um consenso de que os espaços verdes nas grandes machas urbanas contemporâneas devem ser cada vez mais numerosos e simultaneamente mais sustentáveis, estando adaptados às condições edafoclimáticas do local e com custos de manutenção reduzidos. No caso do Algarve, onde a investigação desta dissertação se centra, a disponibilidade hídrica atual e futura, assume um papel preponderante na conceção de espaços verdes, onde as exigências acima mencionadas só poderão ser concretizadas se nos desviarmos de práticas paisagistas convencionais e desenvolvermos estratégias holísticas de gestão e conceção dos espaços verdes que integrem diferentes áreas do conhecimento e não meramente as questões estéticas. Neste contexto, esta dissertação tem como objetivo resgatar práticas paisagistas mais adaptadas e resilientes às condições climáticas do Algarve, reinventando assim o conceito de jardim nesta região de Portugal.
Nesta dissertação apresentam-se dois projetos de jardins xerófilos, em conjunturas distintas (privada e pública). Porém, ambos os projetos consideram espécies vegetais perfeitamente adaptadas a longos períodos de secura climática, que, segunda as previsões de modelos climáticos recentes, terá tendência a se agravar na região do Algarve. Assim, será de sobremaneira importante desenvolver projetos mais sustentáveis, resilientes e tolerantes ao agravamento das condições ecológicas, particularmente às limitações associadas à disponibilidade hídrica.
As suculentas xeromórficas constituem um grupo de plantas, com mecanismos de tolerância ao stress hídrico e com características bem específicas, sendo a suculência uma das mais relevantes. Estudos sobre estes mecanismos são cada vez mais frequentes, o que poderá se mostrar bastante vantajoso na nossa adaptação aos desafios climáticos futuros. Além disso, o seu potencial ornamental é enorme, uma vez que as suas formas arrojadas e panóplia de cores são uma verdadeira explosão sensorial, que aliada às suas características morfológicas e fisiológicas as torna efetivamente espécies de eleição na reconversão ou criação de jardins xerófilos.Considering the current climate conjuncture, it is a consensus that green spaces in large contemporary urban areas should be increasingly more numerous and simultaneously more sustainable, being adapted to the edaphoclimatic conditions of the site, and with reduced maintenance costs. In the case of Algarve, where the research of this dissertation is focused, the current and future water availability, assumes a preponderant role in the design of green spaces, where the demands mentioned above can only be achieved if we deviate from conventional landscape practices and develop holistic strategies of management and design of green spaces that integrate different areas of knowledge and not merely aesthetic issues. In this context, this research aims to develop landscaping practices more adapted and resilient to the current and future climatic conditions of the Algarve, thus reinventing the concept of landscaping in the south of Portugal.
In this work we present, two different approaches of xerophytic landscaping projects (private and public). However, both projects consider species perfectly adapted to long periods of drought, which, according to the predictions of recent climatic models, will tend to worsen in the Algarve. Thus, it will be of paramount importance to develop more sustainable, resilient and tolerant projects to worsening ecological conditions, particularly limitations associated with water availability.
The xeromorphic succulents are a group of plants with mechanisms of tolerance to water stress and with very specific characteristics, being succulence one of the most relevant. Studies on these mechanisms are increasingly frequent, which may prove to be very advantageous in our adaptation to future climatic challenges. In addition, their ornamental potential is enormous, since their bold forms and panoply of colours are a veritable sensory explosion, which, combined with their morphological and physiological characteristics, make them the species of choice in the reconversion or creation of xerophilous gardens
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
