Standard Essential Patents e licenze a condizioni FRAND nel diritto della UE: equità e ragionevolezza tra antitrust e regolazione
2021
L’articolo affronta la controversa questione della determinazione delle condizioni per la concessione di licenze su brevetti essenziali per l’applicazione di uno standard, evidenziando come si sia rivelata inefficiente la scelta della Commissione UE di affidarla esclusivamente alla privata negoziazione dei termini degli impegni FRAND. Tale sistema ha generato un rilevante contenzioso, spesso affrontato con l’applicazione dell’art. 102 TFUE. Scarso aiuto hanno fornito le indicazioni fornite dalla stessa Commissione con diverse comunicazioni, il cui contenuto viene criticamente esaminato, e la pronuncia della Corte di giustizia sul caso ZTE/Huawei. L’autore è dell’idea che sia venuto il momen…
Dimensions of household food waste focused on family and consumers
2020
Food waste produced in homes represents the largest fraction of food waste generated along the food chain. Therefore, adequate prevention measures based on the quantitative and qualitative dimensions of the problem need to be put in place to reduce waste. The objective of the review was to identify areas of interest in relation to the food waste in households, considering the family unit as a whole as well as individual family members. Quantifying the problem is an important aspect in order to know its scope and dimension, but prevention also involves knowing the causes in a home. This is a complex issue, which, on a family level, is related to socioeconomic status, educational level, compo…
Family interventions in schizophrenia: an analysis of non-adherence.
1999
Montero I, Asencio AP, Ruiz I, Hernandez I. Family interventions in schizophrenia: an analysis of non-adherence. Acta Psychiatr Scand 1999: 100: 136–141. © Munksgaard 1999. Objective: The aim of this study was to identify baseline factors which may make it possible to predict non-adherence to prescribed treatment. Method: A total of 87 schizophrenic patients in a catchment area of Valencia (Spain) were randomly assigned to two family strategies. The characteristics associated with lack of adherence to the programmes were analysed in both the patients and their families. Results: Older patients, those with a higher number of previous hospital admissions, those living in small households and …
Challenges on accessing finance for micro-enterprises in Latvia
2021
Financial support of companies for their development is considered and realised by many countries worldwide, also in Latvia. Latvia has been receiving critical remarks from entrepreneurs in regard to high level of refuse for financing from the financing institution ALTUM which is the principal intermediary of EU funds and provides resources to support entrepreneurship in Latvia. Statistical data indicate that there are significant reductions of micro-enterprises during recent years. The survey data showed that ALTUM rejected 39 % of the surveyed micro-enterprises from those who had submitted applications within three years. In turn, only 6 % of micro-enterprises have received full financing…
Urea as a PCDD/F inhibitor in municipal waste incineration.
2001
Emissions of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) from municipal waste incineration have been widely studied because of their extensive toxicity, and many efforts have been made to restrict their emissions. Although a number of chemical compounds have been shown in laboratory-scale tests to inhibit the formation of PCDD/Fs, few have been tested in pilot- or full-scale plants. This work evaluates the effect of urea as a PCDD/F inhibitor in a pilot-scale incinerator that uses refuse-derived fuel (RDF). The decomposition of urea under the test conditions was also studied using detailed kinetic modeling. An aqueous solution of urea was injected into the flue gas stream …
Towards controlling PCDD/F production in a multi-fuel fired BFB boiler using two sulfur addition strategies. Part I: Experimental campaign and results
2014
Abstract Levels of PCDD/F production in a 140 MW th bubbling fluidized bed boiler were measured. The boiler uses solid recovered fuel, bark and sludge. Homologue distribution patterns suggest the de novo mechanism is the main pathway for the generation of dioxin and furans in the post combustion zones of the boiler. Two modes of sulfur addition were tested to induce the deactivation of Cu which has been identified as the prime catalyst of this mechanism. First, S-pellet promoted Cu sulfation as supported by aerosol sampling data and resulted in a decrease in PCDD/F levels. The second approach was adding sulfur through peat; this resulted in an increase in PCDD/F concentration. Factors such …
Cogeneration from thermal treatment of selected municipal solid wastes. A stoichiometric model building for the case study on Palermo
2003
This paper aims to calculate the energetic and environmental effects of an integrated solid waste management system in Palermo, Italy. In particular, the thermal treatment of Municipal Solid Waste (MSW) with energy recovery is assessed. The current characterization at the local scale is taken into account. Two different options of collection are taken into account: (1) unselected wastes; and (2) sorted collection, according to the current Italian regulation. Combustion process is analyzed and the following features are calculated: (1) stoichiometric content of air and air excess; and (2) temperature and enthalpy of flue gases. Energy recovery is performed in the hypothesis of Hirn cycle bot…
Landfill gas upgrading with countercurrent water wash.
2006
A pilot-scale countercurrent absorption process for upgrading landfill gas to produce vehicle fuel was studied using absorption and desorption units and water as absorbent. The height-to-diameter ratio of the absorption column used was 3:1 instead of the more conventionally used 20:1 ratio, and a higher pressure was used along with a lower water flow rate. The effects of pressure (10-30 bar) and water and gas flow-ratios on the upgrading process were studied. Methane content in the product gas increased to near or above 90% with both gas flows (50 and 100 l/min) used at over 20 bar pressure with 10 l/min water flow and at 30 bar pressure with 5l/min water flow. Carbon dioxide content with t…
Mechanically-biologically treated municipal solid waste as a support medium for microbial methane oxidation to mitigate landfill greenhouse emissions.
2005
The residual fraction of mechanically-biologically treated municipal solid waste (MBT residual) was studied in the laboratory to evaluate its suitability and environmental compatibility as a support medium in methane (CH(4)) oxidative biocovers for the mitigation of greenhouse gas emissions from landfills. Two MBT residuals with 5 and 12 months total (aerobic) biological stabilisation times were used in the study. MBT residual appeared to be a favourable medium for CH(4) oxidation as indicated by its area-based CH(4) oxidation rates (12.2-82.3 g CH(4) m(-2) d(-1) at 2-25 degrees C; determined in CH(4)-sparged columns). The CH(4) oxidation potential (determined in batch assays) of the MBT re…
Estimation of biogas produced by the landfill of Palermo, applying a Gaussian model
2008
Abstract In this work, a procedure is suggested to assess the rate of biogas emitted by the Bellolampo landfill (Palermo, Italy), starting from the data acquired by two of the stations for monitoring meteorological parameters and polluting gases. The data used refer to the period November 2005–July 2006. The methane concentration, measured in the CEP suburb of Palermo, has been analysed together with the meteorological data collected by the station situated inside the landfill area. In the present study, the methane has been chosen as a tracer of the atmospheric pollutants produced by the dump. The data used for assessing the biogas emission refer to night time periods characterized by weak…
