The use of industrial waste materials for the simultaneous removal of ammonium nitrogen and phosphate from the anaerobic digestion reject water
2020
The European Union’s circular economy strategy aims to increase the recycling and re-use of products and waste materials. According to the strategy, the use of industry waste materials and side flows is required to be more effective. In this research, a chemical precipitation method to simultaneously remove ammonium and phosphate from the reject water of anaerobic digestion plant using calcined paper mill sludge and fly ash as a precipitant, was tested. Paper mill sludge is a waste material formed in the paper-making process, and fly ash is another waste material formed in the power plant. Objective of this research was to test whether these industrial waste streams could be used as low cos…
Gaming for health across various areas of life
2019
Lack of physical activity is mostly addressed by implementing programs to promote physical activity but seeing as the major cause for physical inactivity is that of technology. Few studies used the approach to use the very barrier as s mean to try and educate and breed good habits. This paper outlines the design and development of a project that will us various environments, home, gym and outdoors to promote physical activity by means of technology and more specifically games. peerReviewed
Pyöräilyn hyötysuhteiden yhteyksiä
2017
Pyöräilytyössä hyötysuhdetta (ulkoisen polkemistyön suhdetta kokonaisenergiankulutukseen)on helppo tutkia ja tällaiseen metaboliseen tehokkuuteen onkin määritelty monia erilaisia mittareita. Fysiologisten ja biomekaanisten muuttujien vaikutuksia näihin eri tavoin määritettyihin hyötysuhteisiin tunnetaan hyvinkin, mutta tätä ennen ei olla juurikaan tutkittu mitkä ovat eri tavoin määriteltyjen hyötysuhteiden keskinäiset suhteet. Tutkimukseen osallistui 14 perustervettä fyysisesti aktiivista 31 ± 6 vuotiasta mies- (n = 12)ja naistutkittavaa (n = 2). Tutkittaville laskettiin kuusi erilaista metabolisen tehokkuuden arvoa: vakioteholla (150 W) kokonais- ja nettohyötysuhde, kaksi työhyötysuhdetta …
Use of Fe and Al containing electrocoagulation sludge as an adsorbent and a catalyst in water treatment
2023
In this study, three different electrocoagulation (EC) sludges were studied as an adsorbent (removal of humic acids) and as a catalyst [catalytic wet peroxide oxidation (CWPO) of bisphenol A (BPA)]. The sludges originated from electrocoagulation process in which aluminum (Al) and iron (Fe) electrodes were used for the treatment of mining industry wastewater. All the materials were used as dried sludge and calcined material. The stability of these materials was studied in neutral and alkaline conditions with analysis of the leached iron content in solution. Based on the EC sludge characterization with X-ray fluorescence (XRF), X-ray diffractometer (XRD), and diffuse-reflectance infrared Four…
Utilizing online serious games to facilitate distributed requirements elicitation
2015
Online serious games are used to facilitate distributed requirements elicitation.Interactive games enhance collaboration and communication between project members.Serious games raise individuals' confidence to engage in requirements elicitation.Using serious games can improve both quality and quantity of software requirements.Serious games specially enhance the performance of less-experienced stakeholders. Requirements elicitation is one of the most important and challenging activities in software development projects. A variety of challenges related to requirements elicitation are reported in the literature, of which the lack of proper communication and knowledge transfer between software …
ISEBA – A Framework for IS Evolution Benefit Assessment
2005
Decisions regarding information system evolution strategy, including modernization or replacement, are economically significant. Selection of a proper method for analyzing potential options, acquisition of suitable metrics or follow-up data, and evaluation of the results are major challenges in the evolution strategy decision making. In order to address these challenges, a framework for Information System Evolution Benefit Assessment (ISEBA) was developed. ISEBA provides assistance in the selection of a benefit-evaluation method for the investment situation at hand. It is based on empirical research on industrial decision making and co-operation projects, and examination of existing researc…
Fyysisen aktiivisuuden ja unen yhteys ikääntyneillä henkilöillä
2012
Ikääntyessä erilaisten uniongelmien määrä lisääntyy ja unen laatu heikkenee. Uniongelmien hoidossa suositellaan lääkkeettömiä hoitokeinoja ja fyysisen aktiivisuuden lisäämistä. Aikaisempien tutkimustulosten perusteella fyysisellä aktiivisuudella on positiivinen yhteys parempaan unen laatuun, mutta se ei ole täysin kiistaton. Tämän pro gradu-tutkielman tarkoituksena oli selvittää fyysisen aktiivisuuden määrän ja intensiteetin yhteyttä unen laatuun, määrään ja uniongelmiin 68- 72-vuotiailla miehillä ja naisilla. Tutkimuksessa käytettiin Ikihyvä Päijät- Häme- kehittämishankkeen vuoden 2008 kyselylo-makkeiden aineistoa. Otos koostui 820 henkilöstä, joista miehiä oli 382 ja naisia 438. Fyysisen …
