Lavatanssiko liikuntaa? : lavatanssi-illan fyysinen aktiivisuus ja kuormittavuus sekä niihin yhteydessä olevat tekijät
2012
Lavatanssi on kasvattanut suosiotaan viime vuosikymmeninä. Terveys- ja kuntoliikuntamuotona sitä on tutkittu varsin vähän. Tutkimuksen tarkoituksena oli selvittää lavatanssin fyysistä aktiivisuutta ja kuormittavuutta sekä niihin yhteydessä olevia tekijöitä. Yhden tanssi-illan aikana tammikuussa 2011 tanssijoiden fyysistä kuormittavuutta mitattiin sykemittareilla ja fyysistä aktiivisuutta selvitettiin askelmittareilla. Taustatietoja kerättiin sähköisellä kyselylomakkeella. Tutkimukseen osallistui 58 vapaaehtoisesti ilmoittautunutta tanssinharrastajaa. Kolmen tunnin lavatanssi-illan aikana tutkittavien keskisyke oli 116 ± 16 bpm, korkein syke 160 ± 15 bpm, ja energiankulutus miehillä 2043 ± 5…
Multicriteria evaluation of alternatives for remote monitoring systems of municipal buildings
2014
Abstract Conservation of natural resources drives municipalities to monitor their heat, power and water consumption more accurately. The objective of this study was to evaluate different implementation possibilities for remote monitoring systems for the municipal buildings of two medium-sized municipalities, Hollola and Nastola in Southern Finland. Four different alternatives were considered: (1) a system by an external service provider, (2) a system provided by the local energy distribution company, (3) a system built by the municipalities themselves, and (4) using the current manual system but with more frequent data collection. The alternatives were evaluated in terms of multiple functio…
Gill area explains deviations from body size–metabolic rate relationship in teleost fishes
2022
Whether gill area constrains fish metabolism through oxygen limitation is a debated topic. Here, the authors provide insights into this question by analysing mass-specific metabolic rates across 44 teleost fishes extracted from FishBase. They explore whether species deviations from metabolic rates predicted by body mass can be explained by species gill area. They show that the gill area explains c. 26%–28% of species-level deviations from mass-specific metabolic rates. Their findings suggest that gill area might indeed be one of the factors limiting metabolic rate in fishes.
Predicting fruit and vegetable consumption in long-haul heavy goods vehicle drivers : application of a multi-theory, dual-phase model and the contrib…
2018
Fruit and vegetable intake is insufficient in industrialized nations and long-haul heavy goods vehicle (HGV) drivers are considered a particularly at-risk group. The aim of the current study was to test the effectiveness of a multi-theory, dual-phase model to predict fruit and vegetable consumption in Australian long-haul HGV drivers. A secondary aim was to examine the effect of past fruit and vegetable consumption on model paths. A prospective design with two waves of data collection spaced one week apart was adopted. Long-haul HGV drivers (N = 212) completed an initial survey containing theory-based measures of motivation (autonomous motivation, intention), social cognition (attitudes, su…
Engine/Transmission Matching
2014
This chapter deals with the forecasting of vehicle performance on the road, according to the installed engine. It begins with Section 1, which shows the calculation of the resistance to motion, that is, the forces that the vehicle must overcome to advance on flat roads and uphill. The calculation excludes accidental resistance in curves because it is not essential for predicting the behavior of the vehicle on the road. Section 2 begins with the power characteristic, the forecast by traction–speed and power–speed diagrams, calculation of gear ratios, and then passing to the limits to the estimated acceleration, feature consumption, and distance. This chapter concludes with a section on the d…
On the effects of transmit power control on the energy consumption of WiFi network cards
2009
Transmit power control has been largely proposed as a solution to improve the performance of packet radio systems in terms of increased throughput, spatial reuse and battery lifetime for mobile terminals. However, the benefits of transmit power control schemes on these different performance figures may strongly depend on the employed PHY technology and channel access mechanism. In this paper, we focus on the effects of power control on the energy consumption of WiFi network cards. By means of several experimental tests carried out under different operation conditions and modulation schemes, we try to justify why the reduction of the transmission power has a marginal effect on the overall en…
Energy efficient model for biogas production in farm scale
2011
Energy efficient solutions for six farm biogas production was found by calculating mass and energy balance in different scenarios. Raw materials in biogas production were cow manure and grass silage that were produced in these farms. There were calculated mass and energy balances on average for one year biogas prouduction that consisted of grass silage production, raw material transportation and biogas production in the biogas plant. In addition, direct greenhouse gases from biogas production were estimated. The direct mass and energy flows were calculated. It turned out that one input energy unit can produce 5.0 to 5.5 energy units as heat and electricity. Biogas reactor consumed heat from…
Gender Trends in Tourism Destination
2013
Abstract The tourism experience was perceived traditionally in terms of products, destinations and consumption patterns. The “new mobility turn” sees the holiday experience as “performance”, “surveillance”, “play”, relationships “at-a-distance”, the impermanence of “sandcastles”, place making, etc. Gale (2007) stated five principles of this turn in tourism: it studies the mobility of individuals; it acknowledges material and immaterial structures; it deals with immobility and power relations; it recognizes virtual and imaginative forms of mobility; and it is concerned with environmental and global consequences. Destinations are not perceived now as fixed unities but as“sandcastles” made of …
Stationary, Second Use Battery Energy Storage Systems and Their Applications: A Research Review
2021
The global demand for electricity is rising due to the increased electrification of multiple sectors of economic activity and an increased focus on sustainable consumption. Simultaneously, the share of cleaner electricity generated by transient, renewable sources such as wind and solar energy is increasing. This has made additional buffer capacities for electrical grids necessary. Battery energy storage systems have been investigated as storage solutions due to their responsiveness, efficiency, and scalability. Storage systems based on the second use of discarded electric vehicle batteries have been identified as cost-efficient and sustainable alternatives to first use battery storage syste…
Football match attendance in Finland
2022
Football fans prefer to see their favourite team win in close matches. Compared to other forms of entertainment, the outcome of sport game is unknown beforehand. Opera audience knows the plot in advance, but in football the winner is revealed only after 90 minutes. The scientific literature of modern sport economics demand theory implies that successful leagues must be based on relatively even competition. This degree of parity within a league is labelled as competitive balance. Sport leagues usually claim that outcome uncertainty is necessary to maintain interest among fans. In this paper, uncertainty of outcome hypothesis is tested applying football data from the highest tier in Finnish m…
