The preference and costs of sleeping under light at night in forest and urban great tits

2019

Artificial light at night (ALAN) is an increasing phenomenon associated with worldwide urbanization. In birds, broad-spectrum white ALAN can have disruptive effects on activity patterns, metabolism, stress response and immune function. There has been growing research on whether the use of alternative light spectra can reduce these negative effects, but surprisingly, there has been no study to determine which light spectrum birds prefer. To test such a preference, we gave urban and forest great tits (Parus major) the choice where to roost using pairwise combinations of darkness, white light or green dim light at night (1.5 lux). Birds preferred to sleep under artificial light instead of dar…

Mitochondrial bioenergetic pathways in blood leukocyte transcriptome decrease after intensive weight loss but are rescued following weight regain in …

2021

Prolonged periods of energy deficit leading to weight loss induce metabolic adaptations resulting in reduced energy expenditure, but the mechanisms for energy conservation are incompletely understood. We examined 42 healthy athletic females (age 27.5 +/- 4.0 years, body mass index 23.4 +/- 1.7 kg/m(2)) who volunteered into either a group dieting for physique competition (n = 25) or a control group (n = 17). The diet group substantially reduced their energy intake and moderately increased exercise levels to induce loss of fat mass that was regained during a voluntary weight regain period. The control group maintained their typical lifestyle habits and body mass as instructed. From the diet g…

Nykyaikaista naista luomassa : Kotilieden, Emäntälehden ja Toverittaren pukeutumisohjeet kansalaiskasvatuksena 1920- ja 1930-luvuilla

2019

Suomalaisen 1900-luvun alun porvarillisen naisliikkeen tavoitteena oli kasvattaa sivistyneitä, siveellisiä, taloudellisia ja ahkeria naisia. Tässä artikkelissa Arja Turunen tutkii, kuinka uudenlaisia naiskansalaisuuden ihanteita opetettiin naistenlehtien pukeutumisohjeiden kautta. Artikkelin aineistona ovat 1920- ja 1930-luvuilla Kotiliedessä, Emäntälehdessä ja Toverittaressa julkaistut pukeutumista ja muotia käsitelleet jutut. Lehtien säästäväisyyttä ja käytännönläheisyyttä painottaneet pukeutumisneuvot heijastivat lukijoiden taloudellista tilannetta, mutta artikkelissa osoitetaan, että ne samalla edustivat myös kulutuskulttuurin tuloa sekä kytkeytyivät aikakauden kansalaiskasvatuksen tavo…

Physical dose of therapeutic exercises in institutional neck rehabilitation

2013

Objective: To determine the intensity and volume of therapeutic exercises during a standard 13-day inpatient neck rehabilitation course in relation to overall physical activity in rehabilitation and everyday life. Design: Cross-sectional study. Methods: Subjects (n=19; 16 women and 3 men; mean age 48.6 years, standard deviation (SD) 6.6) with chronic nonspecific neck pain were recruited from two inpatient neck rehabilitation courses. Intensity and volume of therapeutic exercises and physical activity were measured in metabolic equivalents (METs) with an objective measurement device and all-time recall questionnaire. Maximum oxygen uptake was determined in METs (METc) by direct maximal cycle…

Disparities in nutritional adequacy of diets between different socioeconomic groups of Finnish adults

2022

Information on dietary adequacy is needed to assess food and nutrition security in a modern society, especially in the transition towards climate-friendly food systems. In this study, differences in the nutritional adequacy of diets among Finnish adults were evaluated in population groups of different education, income and urbanisation levels. The study used data from the FinDiet 2017 Survey (n = 1655, 18–74 years). Modelled usual intakes of foods and nutrients were evaluated relative to food-based dietary guidelines issued by the National Nutrition Council of Finland (FNNC) and with respect to nutrient adequacy following the Nordic Nutrition Recommendations and FNNC. For about half of the …

Mitigating the Climate Change Impacts of Aviation through Behavioural Change

2020

Aviation plays a crucial role for economic development and social welfare, but at the same time it also significantly contributes to climate change. Therefore, if the industry wants to follow the same growth path as it has in the past, it will need to mitigate its environmental impacts more seriously or it may otherwise face regulatory restrictions. The current literature has discussed five mitigation strategies. These are technological changes, market-based changes, operational changes, regulatory changes and behavioural changes. While several authors have regarded behavioural changes as the measure with the greatest mitigation potential, it is also the measure that has received far less a…

Acute Metabolic Response, Energy Expenditure, and EMG Activity in Sitting and Standing

2017

Purpose While merely standing up interrupts sedentary behavior, it is important to study acute metabolic responses during single bouts of sitting and standing to understand the physiological processes affecting the health of office workers. Methods Eighteen healthy middle-age women 49.4 ± 7.9 yr old (range: 40–64) with a body mass index of 23.4 ± 2.8 kg·m−2 volunteered for this laboratory-based randomized crossover trial where they performed 2 h desk work in either sitting or standing postures after overnight fasting. Muscle activity (normalized to walking at 5 km·h−1), respiratory gas exchange, and blood samples were assessed after glucose loading (75 g). Results Compared with seated work,…

Energy-efficient quantum computing

2016

In the near future, a major challenge in quantum computing is to scale up robust qubit prototypes to practical problem sizes and to implement comprehensive error correction for computational precision. Due to inevitable quantum uncertainties in resonant control pulses, increasing the precision of quantum gates comes with the expense of increased energy consumption. Consequently, the power dissipated in the vicinity of the processor in a well-working large-scale quantum computer seems unacceptably large in typical systems requiring low operation temperatures. Here, we introduce a method for qubit driving and show that it serves to decrease the single-qubit gate error without increasing the a…

Reducing Power Consumption of Wireless Networks Through Collaborative DMC Mobile Clusters

2017

Reducing the energy consumption of the wireless network is significantly important to the economic and ecological sustainability of the ICT industry, as high energy consumption may limit the performance of wireless networks and is one of the main network costs. To solve energy consumption problem, especially on the terminal side, a scheme known as distributed mobile cloud (DMC) is considered to be a potential solution. Multiple mobile terminals (MTs) can cooperative to take advantage of good quality links among the MTs to save energy when receiving from the Base Station (BS). In this paper, we aim to find the optimal transmit power to further reduce the energy consumption of DMC. From simul…
