Work-related biomechanical exposure and job strain in midlife separately and jointly predict disability after 28 years: a Finnish longitudinal study
2017
Objectives We investigated whether the extent of biomechanical exposures and job strain in midlife separately and jointly predict disability in old age. Methods Participants of the Finnish Longitudinal Study on Aging Municipal Employees (FLAME) in 1981 (aged 44–58 years) responded to disability questionnaires in 2009 (1850 women and 1082 men). Difficulties in performing five activities of daily living (ADL) and seven instrumental ADL (IADL) were used to assess severity of disability (score range: 0–12, 0=no disability). Information on biomechanical exposures and job strain was collected by questionnaire at baseline. Adjusted prevalence proportion ratios (PR) and 95% confidence intervals (95…
Glyphosate-based herbicide has soil-mediated effects on potato glycoalkaloids and oxidative status of a potato pest
2020
Glyphosate is the most used herbicide worldwide, targeting physiological pathways in plants. Recent studies have shown that glyphosate can also cause toxic effects in animals. We investigated the glyphosate-based herbicide (GBH)-induced changes in potato (Solanum tuberosum) plant chemistry and the effects of a GBH on the survival rate and oxidative status of the Colorado potato beetle (Leptinotarsa decemlineata). The beetles were reared on potato plants grown in pots containing soil treated with a GBH (Roundup Gold, 450 g/l) or untreated soil (water control). The 2nd instar larvae were introduced to the potato plants and then collected in 2 phases: as 4th instar larvae and as adults. The ma…

Comparing Surface and Fine-Wire Electromyography Activity of Lower Leg Muscles at Different Walking Speeds.
2019
Ankle plantar flexor muscles are active in the stance phase of walking to propel the body forward. Increasing walking speed requires increased plantar flexor excitation, frequently assessed using surface electromyography (EMG). Despite its popularity, validity of surface EMG applied on shank muscles is mostly unclear. Thus, we examined the agreement between surface and intramuscular EMG at a range of walking speeds. Ten participants walked overground at slow, preferred, fast, and maximum walking speeds (1.01 ± 0.13, 1.43 ± 0.19, 1.84 ± 0.23, and 2.20 ± 0.38 m s–1, respectively) while surface and fine-wire EMG activities of flexor hallucis longus (FHL), soleus (SOL), medial gastrocnemius (MG…
Scalable Constant pH Molecular Dynamics in GROMACS
2022
Molecular dynamics (MD) computer simulations are used routinely to compute atomistic trajectories of complex systems. Systems are simulated in various ensembles, depending on the experimental conditions one aims to mimic. While constant energy, temperature, volume, and pressure are rather straightforward to model, pH, which is an equally important parameter in experiments, is more difficult to account for in simulations. Although a constant pH algorithm based on the λ-dynamics approach by Brooks and co-workers [Kong, X.; Brooks III, C. L. J. Chem. Phys.1996, 105, 2414–2423] was implemented in a fork of the GROMACS molecular dynamics program, uptake has been rather limited, presumably due to…

Derridas filosofi og kvantefysikken : om Derridas filosofi som grunnlag for en lingvistisk-empiriristisk forståelse av fysikken, med anvendelse på kv…
2005
Med utgangspunkt i Derridas kritikk av Husserl beskrives og kritiseres det tradisjonelle intuisjonistiske synet på fysikken. Dette foreslås erstattet med en lingvistisk empirisme, basert på Derridas språkfilosofi. Ved å betrakte matematikken i kvantemekanikken som et språk, oppnås en ny tilnærming til kvantemekanikkens tolkningsproblem.

In vivo localized gastrocnemius subtendon representation within the healthy and ruptured human Achilles tendon
2022
The Achilles tendon (AT) is composed of three distinct in-series elastic subtendons, arising from different muscles in the triceps surae. Independent activation of any of these muscles is thought to induce sliding between the adjacent AT subtendons. We aimed to investigate displacement patterns during voluntary contraction (VOL) and selective transcutaneous stimulation of medial (MGstim) and lateral (LGstim) gastrocnemius between ruptured and healthy tendons, and to examine the representative areas of AT subtendons. Twenty-eight patients with unilateral AT rupture performed bilateral VOL at 30% of the maximal isometric un-injured plantarflexion torque. AT displacement was analysed from sagi…

Maastohiihto on huomattavan vaativaa kokovartaloliikuntaa niin fysiologian kuin biomekaniikankin kannalta tarkasteltuna. Latujen kunnostuksen, hiihtovälineiden, hiihtotekniikoiden sekä kilpailumuotojen kehityksen myötä hiihdosta on tullut nopeampaa ja vaativampaa, joka asettaa suurempia haasteita voimantuotolle. Vastaavasti hiihtotutkimuksessa huomio on viime vuosikymmeninä siirtynyt enemmän biomekaniikan suuntaan. Ensimmäiset ulkoisten suksi- ja sauvavoimien mittaukset suoritettiin yli kolmekymmentä vuotta sitten ja useita yhteyksiä voimantuoton ominaisuuksien ja hiihtosuorituskyvyn välillä on sittemmin tunnistettu. Edelleen on kuitenkin epäselvää mitkä ovat tärkeimmät voimamuuttujat kuvaa…
