Se ha comprobado la veracidad de los datos recogidos consultando las páginas web de las revistas y a través del contacto con los editores de las publicaciones. Los resultados muestran que el comportamiento es desigual entre las rev…
Cost-benefit analysis: A comparison between conventional and organic olive growing in the Mediterranean Area
2015
The conversion from conventional to organic management of olive growing has many benefits, such as increase of biodiversity, reduction of soil erosion and lower environmental impact. Since olive represents a main crop in the Mediterranean area, from a social, economic as well as environmental point of view, the aim of this paper has been to determine if the conversion from conventional to organic olive growing can increase the profitability of the farmer in Sicilian farms. Economic analysis has been carried out by means of cost-benefit analysis and financial indicators (NPV, B0/C0, IRR) show that organic growing would allow a better profitability for organic olive farms respect to conventio…
Mathematical Modelling of In-sewer Processes as a Tool for Sewer System Design
2018
The objective of this paper is to evaluate the potential impact of in-sewer processes (COD components transformation and hydrogen sulphide production) on the design of sewer systems. The tool used for such analysis is a mathematical model derived from the WATS model (Wastewater Aerobic/anaerobic Transformation in Sewers) able to describe the processes occurring in the sewer system both under aerobic and anaerobic conditions. The model is applied to three synthetic catchments with, respectively, 10,000, 50,000 and 250,000 inhabitants connected to gravity sewer systems different in terms of type (separate or combined), slope, length, travel time, wastewater temperature. The simulation results…
Ecklonia maxima-derivate seaweed extract supply as mitigation strategy to alleviate drought stress in chicory plants
2023
Extreme climatic conditions have a severe repercussion on agriculture and on food availability. Ecological means to overcome drought are important to improve agroecosystems sustainability and resilience. The use of an Ecklonia maxima-derivate seaweed extract (SwE) as a tool to mitigate drought constrain in chicory plants grown in greenhouse was evaluated. Plants were cultivated in plastic pots filled with peat and subjected to drought stress by retaining moisture range at 90–100% of water holding capacity (WHC) [well-watered (WW)], 60–70% WHC [moderate drought stress (MDS)] or 30–40% WHC [severe drought stress (SDS)]. Drought stress decreased plant growth traits and yield. However, in plant…
Ecotourism in Bolivia : an ethnographical study of ecotourism impacts in Madidi National Park
2016
Master thesis development management - University of Agder 2016 The concepts of ecotourism are widely defined but it is often used as a marketing instrument in order to promote tourism businesses related to nature. Ecotourism experience a fast growth in world tourism industry and many developing countries are trying to use ecotourism as a tool to achieve sustainable development. Ecotourism provides many beneficiaries to local environments, economies and socio-cultural lives. However, ecotourism may as well have harmful effects on those involved. Still, ecotourism conserves and protects local areas and its people. Madidi National Park in Bolivia has been estimated to be one of the world’s mo…
Coverage, efficacy or dosing interval: which factor predominantly influences the impact of routine childhood vaccination for the prevention of varice…
2016
Background Varicella is a highly infectious disease with a significant public health and economic burden, which can be prevented with childhood routine varicella vaccination. Vaccination strategies differ by country. Some factors are known to play an important role (number of doses, coverage, dosing interval, efficacy and catch-up programmes), however, their relative impact on the reduction of varicella in the population remains unclear. This paper aims to help policy makers prioritise the critical factors to achieve the most successful vaccination programme with the available budget. Methods Scenarios assessed the impact of different vaccination strategies on reduction of varicella disease…
Impact of orphan drugs on Latvian budget
2016
Background Number of orphan medicinal products on the market and number of rare disease patients, taking these usually expensive products, are increasing. As a result, budget impact of orphan drugs is growing. This factor, along with the cost-effectiveness of orphan drugs, is often considered in the reimbursement decisions, directly affecting accessibility of rare disease therapies. The current study aims to assess the budget impact of orphan drugs in Latvia. Methods Our study covered a 5-year period, from 2010 to 2014. Impact of orphan drugs on Latvian budget was estimated from the National Health Service’s perspective. It was calculated in absolute values and relative to total pharmaceuti…
Impact of building automation control systems and technical building management systems on the energy performance class of residential buildings: An …
2014
Abstract The paper focuses on the evaluation of the impact on residential buildings of building automation control (BAC) and technical building management (TBM) systems. This work shows how the control, monitoring and automation functions considered by the European Standard EN 15232 can considerably influence the energy performance of a single-family test house and, consequently, its energy performance class. The study puts into evidence that the benefit that can be drawn from the installation of BAC and TBM systems depends on the type of technical appliances in the household and on the starting energy performance class. Finally, the economic impact due to the introduction of BACS or TBM fu…
Economic impact of BACS and TBM systems on residential buildings
2013
The paper presents the results of a study on the economic impact of building automation control systems and technical building management systems on residential buildings. The different functions considered by European Standard EN 15232 and having impact on the energy performance of buildings are applied to a test house, varying its energy efficiency class. The economic impact due to the introduction of each BACS or TBM function is evaluated using the BAC factors method, considering the real costs for the purchase and the installation of the components that implement the specific functions and the yearly energy costs of the building before and after their installation.
