A Study of Osmosis Rate Through Several Proton Conducting Polymer Composite Membranes
2021
Carbon dioxide is typically considered to be a byproduct of various industrial processes that should not be released into the environment due to its nature as a harmful greenhouse gas. One of the more promising ways to dispose of it in an economical and environmentally friendly way is by using it as a raw material in electrochemical synthesis reactors. An important part of such reactors is an ion exchange membrane. In this study the influence of ZrO2 content in SPEEK – ZrO2 composite membranes on rate of osmosis trough them was investigated, with the goal of evaluating ZrO2 as an additive for making ion exchange membranes with fine-tuned osmotic permeability.
Complementary approaches for assessing protein sources in fish feed
2018
Fluctuating fishmeal (FM) prices and declining marine fish stocks have led to the current trend of replacing dietary FM with plant proteins (PP) in fish feed. PPs offer challenges both with respect to nutritional quality and the occurrence of antinutrients. The assessment of utilisation efficiency of PPs for growth is important for the sustainable production of fish feed. The overall aim of this thesis was to investigate the applicability of stable isotope analysis in combination with respirometry in the evaluation of dietary PPs for juvenile rainbow trout (Oncorhynchus mykiss). The dietary PPs were corn gluten meal (CGM), rapeseed protein concentrate (RPC) and potato protein (PoP). Complet…
ANALYSIS OF BUSINESS CYCLES CONVERGENCE IN A SWITCHING REGIME VIEW
2012
In this paper I analyzed the convergence between Romanian and Euro Zone`s business cycles using a Switching approach. Considering the evolution of final consumption expenditure as proxy for the business cycles, the underlying study is calibrated on the second key feature of Burns and Mitchell`s (1946) definition about business cycles, namely the cycles are divided and also treated differently for cases of expansionary and downward regimes. Therefore a cyclical convergence between Romanian and Euro Zone`s business cycles is characterized by synchronization in the occurrence of different regimes (states) and also in the time for which these regimes are standing up. For this purpose, I called …
Effective Tax rates and Fiscal Convergence in the OECD: 1965-2001
2005
In this work we elaborate a data base that includes 21 OECD countries along the 1965-2001 period. It includes average effective tax rates on consumption, capital and labour, which are adequate to analyse macroeconomic effects of fiscal policy. Additionally, we make a description of the most important features of fiscal structures in OECD countries along the last decades. Thus, we find that the ratio of fiscal revenues to GDP has steadily increased in these countries, mainly due to the increase of taxation on labour earnings. This increase in fiscal revenues has gone together with a process of convergence across countries both in the level of fiscal revenues, as in labour and capital tax rat…
Effects of aerobic and strength training on aerobic capacity, muscle strength, and gene expression of lymphomonocytes in patients with stable CAD
2020
This study examined the effectiveness, suitability, and safety of a mixed interval-type aerobic and strength training program (MIAST) on physical fitness in patients with stable coronary artery disease (CAD) without history of myocardial infarction (MI). Twenty-three patients with stable CAD were randomly assigned to a MIAST (n = 12; mean age 58.6 years) or control (n = 11; 63.3 years) group. The MIAST group participated in the progressive training program twice a week for 21 weeks. Peak oxygen uptake (VO2peak), workload, and exercise time were measured as were maximal muscle strength, serum lipids, glucose concentration, and the cross-sectional area (CSA) of knee extensors. The safety and …
Differences in consumer perspectives how sustainable food consumption is perceived and signalled in the prevailing consumer culture : among Generatio…
2016
This thesis investigates Generation Y sustainable food consumers in the prevailing consumer culture and their differences in signalling and perceiving sustainability. The reasons why they engaged to a sustainable diet and the possible conflicts around it were also studied. Relevant contexts around consumer culture, possessions, identities and Generation Y regarding sustainable food consumption were presented as the theoretical framework. The focus was on Generation Y consumers in order to recognize relevant the contexts that influence their behaviour in the marketplace. Qualitative research methods were utilized as the data was gathered through nine in-depth interviews furthermore applied t…
Eettinen kuluttaminen kulutuskulttuurissa
2016
The aim of this dissertation is to contribute to our knowledge and understanding of the various meanings of ethical consumption constructed in consumer culture, especially from consumers’ viewpoint. This doctoral thesis belongs to the field of cultural and interpretive consumption research (CCT). The research consists of an introductory essay and three articles, of which two are published in academic journals. The introductory essay presents the general research task, conceptual framework, and methodological choices and discussion to conclude the main results of the dissertation. The research included in this dissertation uses qualitative methods and applies discursive content analysis, geo…
Values and sustainable food consumption - promoting sustainably produced food products to Finnish consumers
2018
Food consumption and food choices are a vital part of humans’ lifestyles. In addition, it is widely acknowledged that food is one of the key consumption contexts for environmental and social impacts around the world. The purpose of this study is to contribute to the discussion on promoting sustainable food consumption. More specifically, this study provides insights into the promotion of sustainably produced food to consumers as well as into the value orientations linked with sustainable food consumption. This dissertation contributes to the existing literature on sustainable food consumption by showing that such consumption may be motivated by a plethora of value orientations – and their c…
Consumer selection of vegetarian food in restaurants
2015
Development, which began from agricultural and industrial revolutions has improved and eased human lives on this planet. But the massive growth of the human population has caused some serious environmental impacts on our planet. Millions of hectares of forests have been converted into arable land, fresh water resources are decreasing and oceans are getting overfished, while the demand for food continues to grow. Agriculture is the most important contributor to the climate change and global meat production sector causes more greenhouse gases to the atmosphere than transport. By reducing the consumption of meat and increasing the proportion of vegetables in human diets, the environmental impa…
Myth about altruistic organic consumption : values influence in perceiving organic meat consumer
2015
The aim of this study was twofold: Firstly, to find out whether organic meat consumers are perceived pro-social as defined by Griskevicius et al (2010) with attributes: Caring, Altruistic and Nice. The second theme was to find out what values of the perceiver influence that judgement; a glimpse to who finds the organic bacon consumer as pro-social. Quantitative methods were used in this study and an internet survey was conducted within students of University of Helsinki and Aalto University as well as a pre-requited Food West panellists. As anticipated, the results show that the organic bacon consumer is indeed perceived significantly more pro-social than the user of conventional bacon. The…
