La evolución energética del sector español de baldosas cerámicas
2014
espanolEl presente texto analiza como ha ido evolucionando el consumo y la eficiencia energetica de la industria espanola de baldosas ceramicas durante el siglo XX, y explora las posibilidades que se le plantean en el siglo XXI. Durante el pasado siglo este sector industrial acometio tres transiciones radicales al pasar de los combustibles tradicionales de biomasa a los hidrocarburos liquidos (fueloleo y gasoleo), y posteriormente a los gaseosos, principalmente gas natural. Aunque la informacion que permite evaluar de manera fiable la eficiencia energetica real en las plantas de fabricacion no es facil de obtener, los datos disponibles indican que se ha llegado a una elevada eficiencia con …
Nitrous oxide emissions in a membrane bioreactor treating saline wastewater contaminated by hydrocarbons
2016
The joint effect of wastewater salinity and hydrocarbons on nitrous oxide emission was investigated. The membrane bioreactor pilot plant was operated with two phases: i. biomass acclimation by increasing salinity from 10 gNaCl L−1 to 20 gNaCl L−1 (Phase I); ii. hydrocarbons dosing at 20 mg L−1 with a constant salt concentration of 20 gNaCl L−1 (Phase II). The Phase I revealed a relationship between nitrous oxide emissions and salinity. During the end of the Phase I, the activity of nitrifiers started to recover, indicating a partial acclimatization. During the Phase II, the hydrocarbon shock induced a temporary inhibition of the biomass with the suppression of nitrous oxide emissions. The r…
Opiskelijavalinnat uudistuvat : vaihtoehtoisia valintatapoja todistusvalinnan rinnalle
2019
Ylioppilastutkintoon perustuvasta todistusvalinnasta tulee pääasiallinen valintatapa yliopistojen tutkintokoulutukseen. Sen ohelle tarvitaan vaihtoehtoisia tapoja, sillä ylioppilastodistus ei takaa kaikille opiskelupaikkaa. Avoimen yliopiston reitit antavat hakijalle mahdollisuuden pyrkiä yliopistoon aiemmin suoritettujen yliopisto-opintojen perusteella. nonPeerReviewed
Digital Education For All: Multi-University Study of Increasing Competent Student Admissions at Scale
2022
An indubitable way to put learning at scale in practice is to implement Massive Open Online Courses, or MOOCs. When a wide-enough portfolio of them is available, new applications arise. For instance, university admissions in Finland, where this study was conducted, have traditionally been based on students' grades in high school studies, an entrance examination, or a combination of both. A minority of students have been accepted through an open university admission path where students can get a study right if they complete enough university course credits with a high enough grade in a given time frame. In this work, we report results from a multi-university project in which the open univers…
Self-enforcing international environmental agreements revisited
2004
In Barrett's (1994) paper on transboundary pollution abatement is shown that if the signatories of an international environmental agreement act in a Stackelberg fashion, then, depending on parameter values, a self-enforcing IEA can have any number of signatories between two and the grand coalition. Barrett obtains this result using numerical simulations and also ignoring the fact that emissions must be non-negative. Recent attempts to use analytical approaches and to explicitly recognize the non-negativity constraints have suggested that the number of signatories of a stable IEA may be very small. The way such papers have dealt with non-negativity constraints is to restrict parameter values…

Management of Greenhouse Gas Emissions for Airport Inventories
2020
Greenhouse gases retain heat in the atmosphere since they absorb most of the Earth's outgoing long wave infrared radiation. The energy trapping alters the radiative balance that, in turn, modifies weather patterns at a global scale, progressively increasing the natural greenhouse effect. Heattrapping ability of some pollutants and primarily the carbon overload in the atmosphere as a result of human activities which have been protracted over a long period of time, has led to climate change and increase in global average temperature. In a long-term perspective, emission abatement from aviation sector has needed wide-ranging strategies. In this view an inventory of greenhouse gases can be a be…

Replacing short-haul flights with land-based transportation modes to reduce greenhouse gas emissions: the case of Finland
2019
Even though air travel often provides the fastest transport option, it also has the highest climate impact. Especially on long-haul trips, an aircraft usually represents the only feasible option. Nevertheless, aircraft are more often used on short-haul routes as well. It is the short-haul flights that produce the highest emissions per passenger. These are also the ones that could be replaced the most easily by land-based transportation modes. This study investigates the greenhouse gas emissions reduction potential of replacing short-haul flights with train, coach and car travel within Finland while also taking into account real travel times from door to door. Our results showed that replaci…
Carbon emissions by Ssouth american companies: driving factors for reporting decisions and emissions reduction
2018
In the last decade, companies have started to disclose information on carbon emissions. To our knowledge, this is the first paper to look into this phenomenon in South America, which is a very important geographical area regarding climate change because of the local nature and developing economies. This paper explores the relationships between some corporate variables and two important decisions: (i) whether to report carbon emissions, and (ii) the impact on the evolution of carbon emissions. Logit and linear panel data models are used to determine the driving factors for decisions (i) and (ii). Our results show that regarding the carbon reporting decision, a company&rsquo
