Modelo empírico para la determinación de clorofila-a en aguas continentales a partir de los futuros Sentinel-2 y 3. Validación con imágenes HICO
2014
[EN] Chlorophyll-a concentration is one of the main indicators of inland waters quality. Using CHRIS/PROBA images and in situ data obtained in four lakes in Colombia and Spain, we obtained empirical models for the estimation of chlorophyll-a concentration, which can be directly applied to future images of MSI Sentinel-2 and OLCI Sentinel-3 sensors. The models, based on spectral band indices, were validated with data from the hyperspectral sensor HICO, onboard of the International Space Station.
Influence of the Liquefied Starch Composition and pH on the Saccharification at the Obtaining of Maltose Syrup
1970
In this paper the influence of the composition of the liquefied starch and of pH on the quality of saccharification at the obtaining of maltose syrup is investigated. A large number of experiments (68) in various liquefaction conditions show that Dextrose Equivalent (DE) and the composition in hydrolysis products with Degree of Polymerisation higher as four (DP ≥4) in the liquefied starch have a strong influence on the saccharification products, mainly on the maltose content in the maltose syrups. The liquefied starch with DE lower as 25 has smaller amounts of DP ≥4 (40 to 60%), whereas the liquefied starch with DE between 25 and 27 has high amounts of DP ≥4 (60 to 80%). For the production …
Modelling of Starch Gelatinisation and Liquefaction with the Enzyme Liquozyme
2011
In this paper the influence of the enzyme Liquozyme Supra concentration (0.4-1.2 kg/t dry substance DS) and gelatinisation time (3-11 min.) on the liquefied starch quality is investigated. The composition in sugars with different Degrees of Polymerisation (DP) as DP1 (glucose), DP2 (maltose), DP3 (maltotriose), DP4 (maltotetrose) and oligosaccharides with DP≥5 is analysed by using HPLC with RI detector. The products obtained have different DP, the main components being oligosaccharides with DP≥5, followed by small amount of DP3+DP4 and much smaller concentrations of DP1; no DP2 is produced by this enzyme. Two quality criteria: the percent of oligosaccharides with DP≥5 and the percent of DP1…
Cartes et élections : la construction des circonscriptions électorales aux Etats-Unis, entre égalité et équité
2003
Maps and Elections : The Construction of Electoral Districts in the USA. Decennal census-led redistricting in the United States is the occasion for court actions focused nowadays on the political representation of ethnic minorities. Computer tools make possible the building of districts specifically tailored for Blacks or Hispanics, but blatant racial gerrymandering is now rejected by the US Supreme Court. This paper examines the most relevant judicial decisions and describes several local cases.
The Sustainability of Reclaimed Asphalt as a Resource for Road Pavement Management through a Circular Economic Model
2019
The transition of the road engineering industry to a circular way of doing business requires more efficient and sustainable resources, energy, and waste management. The rates in which reclaimed asphalt is being recycled or reused in the asphalt mixture production process constitutes a crucial parameter in this transition. This paper aims at establishing a further step towards the combined circularity and sustainability of asphalt pavements, by introducing a framework for quantifying their Material Circularity Index. The framework is based on the methodology proposed by the Ellen MacArthur Foundation and accordingly tailored for the context of asphalt pavements. This study, thus, attempts to…
European National Road Authorities and Circular Economy: An Insight into Their Approaches
2020
The pavement engineering industry, having realized the significance of the impacts that it imposes on the environment through the production, construction and management of its products and assets, has been driven towards a more sustainable and circular way of operating. This has partly been through asphalt recycling, which is an area that many road authorities have prioritized. However, not all the National Road Authorities (NRAs) and/or sector stakeholders seem to be adequately familiar with the Circular Economy (CE) concept. This paper attempts to assist the transition of NRAs to a more circular way of doing business, by analyzing the current situation of CE within national/regional auth…
CITES, wild plants, and opportunities for crime
2017
The illegal trade in endangered plants damages both the environment and localcommunities by threatening and destroying numerous species and important natural resources. There is very little research which systematically addresses this issue by identifying specific opportunities for crime. This article presents the results of an interdisciplinary study which brings together criminological and conservation science expertise to identify criminal opportunities in the illegal wild plant trade and suggest strategies in order to prevent and mitigate the problem. Methodologically, the study adapts a crime proofing of legislation approach to the UN Convention on the International Trade in Endangered…
Policies can help to apply successful strategies to control soil and water losses. The case of chipped pruned branches (CPB) in Mediterranean citrus …
2018
[EN] There is a need to devise management strategies that control soil and water losses in agriculture land to allow the design of proper policies to achieve sustainability. It is the responsibility of scientists to work with other actors to co-construct strategies that will lead to sustainable land-use policies. Using chipped pruned branches (CPB) as mulch can be a viable option because they represent local (in situ) organic material that can restore soil nutrient and organic matter. This research assesses: i) the perception of farmers towards different types of management strategies and CPB's costs; ii) the biomass yield of citrus branches and the impact of CPB on soil properties; iii) ho…
New Arrivals, Old Places: Demographic Changes and New Planning Challenges in Palermo and Naples
2008
If we look at the demographic changes in the largest cities in Southern Italy, the most significant trend is a balance between population growth and decline, affecting in particular inner urban areas, which is due to the predominance of new ethnic inhabitants. After having described these demographic changes in Naples and Palermo, the paper will include some considerations on the ‘institutional’ landscape of planning and the related policies. How do planning policies and practices face this quick change in such peripheral contexts, which are new to the phenomenon? Can the plural composition of the local society be viewed as an opportunity, and not just as a threat? The paper will use some a…
Urban and Transit Planning. A Culmination of Selected Research Papers from IEREK Conferences on Urban Planning, Architecture and Green Urbanism, Ital…
2020
A volume of five parts, this book is a culmination of selected research papers from the second version of the international conferences on Urban Planning & Architectural Design for sustainable Development (UPADSD) and Urban Transit and Sustainable Networks (UTSN) of 2017 in Palermo and the first of the Resilient and Responsible Architecture and Urbanism Conference (RRAU) of 2018 in the Netherlands. This book, not only discusses environmental challenges of the world today, but also informs the reader of the new technologies, tools, and approaches used today for successful planning and development as well as new and upcoming ones. Chapters of this book provide in-depth debates on fields o…
