15./16.gs. mijas aktualitāšu atspoguļojums Jana Gosārta mākslā
2015
Maģistra darbā „15. / 16. gs. mijas aktaualitāšu atspoguļojums Jana Gosārta mākslā” mērķis ir analizēt Jana Gosārta radīto mākslas darbu sižetu saistību ar 15./16. gs. mijas sabiedriskajām aktualitātēm Nīderlandes teritorijā un novērtēt iespējas iegūtos rezultātus pielietot aplūkojamā laikmeta pētniecībā un izpratnes veidošanā par norisēm tajā. Mērķa realizēšanā tika izmantota ikonoloģiskā metode, kuru izveidojis Ervins Panofskis. Metode paredzēta mākslas darbu analīzei un padara iespējamu no šiem māksals darbiem iegūtās informācijas interpretāciju plašākā, vēsturiskā kontekstā. Rezultātā tika noskaidrots, ka konstatējama saikne Jana Gosārta mākslas darbiem un laikmeta aktualitātēm, kurā ti…
Daytime sensible heat flux estimation over heterogeneous surfaces using multitemporal land‐surface temperature observations
2016
Equations based on surface renewal (SR) analysis to estimate the sensible heat flux (H) require as input the mean ramp amplitude and period observed in the ramp‐like pattern of the air temperature measured at high frequency. A SR‐based method to estimate sensible heat flux (HSR‐LST) requiring only low‐frequency measurements of the air temperature, horizontal mean wind speed, and land‐surface temperature as input was derived and tested under unstable conditions over a heterogeneous canopy (olive grove). HSR‐LST assumes that the mean ramp amplitude can be inferred from the difference between land‐surface temperature and mean air temperature through a linear relationship and that the ramp freq…
On Capturing Oil Rents with a National Excise Tax Revisited
2004
In this paper the scope of Bergstrom’s (1982) results is studied. Moreover, his analysis is extended assuming that extraction cost is directly related to accumulated extractions. For the case of a competitive market it is found that the optimal policy is a constant tariff if extraction is costless. However, with depletion effects, the optimal tariff must ultimately be decreasing. For the case of a monopolistic market the results depend crucially on the kind of strategies the importing country governments can play and on whether the monopolist chooses the price or extraction rate. For a price-setting monopolist it is shown that the importing countries cannot use a tariff to capture monopoly …
Cambio climático y sustentabilidad económica y social: implicaciones sobre el bienestar social
2008
This article puts forward an explanation of climate change within the context of global change. Climate change can be seen as the spearhead; as a manifestation of the increasing unsustainability of planet Earth. We consider some of the effects of this change, examining its uneven impact on developed and under-developed countries. We then put forward various proposals of how to deal with climate change, highlighting Socolow’s theory in particular. Lastly, we move on to the debate raised by climate change, its impact and possible strategic steps to remedy the situation within the context of environmental sustainability. This will probably lead to a new economic, social and environmental parad…

Potential production of biogas from prinkly pear (opuntia ficus-indica L.) in sicilian uncultivated areas
2017
The aim of this work is to evaluate the potential production of biogas and, indirectly, biomethane or electric and thermal energy, from prinkly pear (Opuntia ficus-indica L.), to be grown in a part of Sicilian uncultivated areas and co-digested together with the available livestock manure and slurry. In order to increase the Renewable Energy Sources (RES) and reduce the dependency from fossil ones, the conversion of biomass into biogas through Anaerobic Digestion (AD) process is paramount for producing biomethane, to be used as fuel for means of transport and agricultural machines or heating, or electric and thermal energy through Combined Heat and Power (CHP) plants. Moreover, the digestat…
Land Cadastre in Italy for Sustainable Development: Application to Two Parcels of Land in a Geopark in the Process of Being Defined in Corleone (PA-I…
2020
Geoparks, like all parks, are UNESCO awards for a sustainable management of all resources and therefore also of human life. Environmental emergencies such as climate change, pollution, soil erosion, salinisation, and fires that, together with health emergencies, undermine life on earth, require intervention. The widespread sustainable management of the territory of a municipality, a region, a nation, or all of them (European Union) allows to widen the application of these concepts to reach the limit of a planet that guarantees life for future generations. The work after having exposed the motivations of the geopark (an initiative born by chance), i.e. the surface where the environmental bea…
On the distribution of lightning current among interconnected grounding systems in medium voltage grids
2018
This paper presents the results of a first investigation on the effects of lightning stroke on medium voltage installations' grounding systems, interconnected with the metal shields of the Medium Voltage (MV) distribution grid cables or with bare buried copper ropes. The study enables us to evaluate the distribution of the lightning current among interconnected ground electrodes in order to estimate if the interconnection, usually created to reduce ground potential rise during a single-line-to-ground fault, can give place to dangerous situations far from the installation hit by the lightning stroke. Four different case studies of direct lightning stroke are presented and discussed: (1) two …
El análisis marxista de las necesidades sociales
2018
The disappearance of the so-called «real socialism» has concealed the validity of the Marxist analysis of social reality. One of the sets of hypotheses that has best maintained its heuristic capacity is the Marxist theory of needs. The Marxist hypotheses have been developed in debate with other conventional conceptions. Currently, feminism and the ecological analysis of needs are renewing the views of Heller and Habermas.
Contratto ed emergenza sanitaria in Italia
2021
Questo articolo si propone di analizzare il disastro globale causato dall'epidemia di COVID-19 che ha turbato l'esistenza di quasi tutta l'umanità. Esaminare le significative limitazioni alle libertà individuali e collettive per proteggere la salute pubblica e, in secondo luogo, mitigare il più possibile l'impatto della pandemia sulle attività economiche. L'attenzione dell'articolo si concentrerà esclusivamente sulle norme che impattano sulla disciplina generale delle obbligazioni e dei contratti, tralasciando le importantissime disposizioni in materia di rapporti di lavoro, contratti di mutuo, contratti bancari e assicurativi, ecc. Verificherà fino a che punto la situazione sociale, sanit…
