Electromyographic evaluation of synergist muscles of the pelvic floor muscle depending on the pelvis setting in menopausal women: A prospective obser…
2019
Background: Pelvic floor muscle (PFM) training is recommended to increase their strength and endurance. Muscles which act synergistically with PFM are taken into consideration in the therapeutic management of weakened PFM. Research question: how does electromyography activity of the synergists muscle to PFM change concerning pelvis position and does the greater bioelectric activity of synergist muscles affect PFM function? Methods: A prospective, observational study evaluating the surface electromyography (sEMG) activity of selected synergist muscles of the PFM depending on the orientation of the pelvis. One hundred thirty-one menopausal women registered for the study were screened for incl…
Autonomic regulation of nasal vessels during changes in body position
1994
The effects of postural changes on nasal airflow and nasal capillary blood flow were investigated in 15 healthy volunteers. Measurements were performed following nasal application of saline solution (control), the alpha-1 receptor antagonist prazosin, the alpha-2 receptor antagonist yohimbine, and after application of both prazosin and yohimbine. Nasal airflow in the control experiments did not significantly differ in the upright (362 +/- 166 ml/s), dorsally recumbent (350 +/- 167 ml/s) and 70 degrees head down position (311 +/- 167 ml/s). Following application of prazosin, nasal airflow was reduced to 223 +/- 121 ml/s in the upright position. Prazosin treatment significantly reduced nasal …
Vil økt fysisk aktivitet kunne redusere andelen trygdemottakere? : En case-studie basert på deltakere ved Aktiv på dagtid, Aust-Agder
2018
Masteroppgave offentlig politikk og ledelse ME502 - Universitetet i Agder 2018 This study is based on Aktiv pådagtid as an case study. The purpose of this study is to investigate the relationship between increased participation in physical activities directed by Aktiv på dagtid and the participants status in relation to working life. To better understand the relationship between these two variables, the study include three possible predictors:health, social support and self-efficacy.Thisstudy use a paper-based survey with 144 respondents, which represent the participants atAktiv på dagtid, who are at theage between 16-70, receive social security benefits and resides in the municipalities of…
The SESAMO early warning system for rainfall-triggered landslides
2016
The development of Web-based information systems coupled with advanced monitoring systems could prove to be extremely useful in landslide risk management and mitigation. A new frontier in the field of rainfall-triggered landslides (RTLs) lies in the real-time modelling of the relationship between rainfall and slope stability; this requires an intensive monitoring of some key parameters that could be achieved through the use of modern and often low-cost technologies. This work describes an integrated information system for early warning of RTLs that has been deployed and tested, in a prototypal form, for an Italian pilot site. The core of the proposed system is a wireless sensor network coll…
Miljøterapeutteam i barneverntjenesten : Evaluering av miljøterapeutteam i barnevernstjenesten i Kristiansand kommune
2013
Systematisk bruk av miljøterapeutiske tilnærminger til barn og familier i barnevernet anvendes i varierende grad. Miljøterapeutteamet er et hjemmebasert tiltak for familier som er i behov at hjelpetiltak etter lov om barneverntjenester § 4-4. Tiltaket er et førstelinjetilbud i Kristiansand barneverntjeneste. Familiene som teamet arbeider med blir henvist fra barneverntjenestens saksbehandlere. Etter ønske fra ledelsen i barneverntjenesten ble teamet opprettet for å arbeide målrettet inn i familier i en avgrenset periode. Hensikten var å gi målrettede og virkningsfulle hjelpetiltak i en presset situasjon hvor mye tid og ressurser gikk til meldingsgjennomganger, undersøkelser, tiltakssaker og…
Næromsorgsør : En evaluering av et hjemmebasert tiltak for jenter i alderen 14-18 år
2007
Denne rapporten er en beskrivende evaluering av Næromsorg Sør`s arbeid med jenter i alderen 14-18 år. Næromsorg Sør er en privat stiftelse som presenterer seg blant annet som et tiltak som retter fokus på jenter og gutter i alderen 13-18 år, der rus-, psykiatri- eller atferdsproblematikk er utprega, og deres familier. Det er et nærmiljø- /næromsorgstiltak, som også kan være et alternativ til institusjonsplassering. Det jobbes med relasjoner og målet er å skape ny mestringstillit både hos jenta/gutten og familien. Tiltaket benyttes av barneverntjenesten som et hjelpetiltak med hjemmel i Lov om barneverntjenester § 4-4, første ledd. Problemene til jentene som utgjør utvalget i denne undersøke…
Mutual nonlinear prediction of cardiovascular variability series: Comparison between exogenous and autoregressive exogenous models
2007
A model-based approach to perform mutual nonlinear prediction of short cardiovascular variability series is presented. The approach is based on identifying exogenous (X) and autoregressive exogenous (ARX) models by K-nearest neighbors local linear approximation, and estimates the predictability of a series given the other as the squared correlation between original and predicted values of the series. The method was first tested on simulations reproducing different types of interaction between non-identical Henon maps, and then applied to heart rate (HR) and blood pressure (BP) variability series measured in healthy subjects at rest and after head-up tilt. Simulations showed that different c…
Hydrophobic mismatch of mobile transmembrane helices: Merging theory and experiments
2012
Abstract Hydrophobic mismatch still represents a puzzle for transmembrane peptides, despite the apparent simplicity of this concept and its demonstrated validity in natural membranes. Using a wealth of available experimental 2 H NMR data, we provide here a comprehensive explanation of the orientation and dynamics of model peptides in lipid bilayers, which shows how they can adapt to membranes of different thickness. The orientational adjustment of transmembrane α-helices can be understood as the result of a competition between the thermodynamically unfavorable lipid repacking associated with peptide tilting and the optimization of peptide/membrane hydrophobic coupling. In the positive misma…
Ferroelectric polysiloxane liquid crystals with ‘de Vries’-type smectic A*–smectic C* transitions
2004
We report preliminary results of optical and small angle X-ray scattering (SAXS) experiments on the smectic A*−smectic C* transition in two ferroelectric liquid crystalline polysiloxanes. Although the optical tilt angle in the SmC* phases reaches values up to 30°, temperature-dependent SAXS measurements clearly reveal that the smectic layer spacing is basically conserved during the A*–C* transition as well as in the subsequent C* phase. Connected with the A*–C* transition we further observed a significant increase in birefringence, hence reflecting an increase of orientational order. The practical absence of layer shrinkage and the enhanced orientational ordering are consistent with the de …
Bivariate nonlinear prediction to quantify the strength of complex dynamical interactions in short-term cardiovascular variability.
2005
A nonlinear prediction method for investigating the dynamic interdependence between short length time series is presented. The method is a generalization to bivariate prediction of the univariate approach based on nearest neighbor local linear approximation. Given the input and output series x and y, the relationship between a pattern of samples of x and a synchronous sample of y was approximated with a linear polynomial whose coefficients were estimated from an equation system including the nearest neighbor patterns in x and the corresponding samples in y. To avoid overfitting and waste of data, the training and testing stages of the prediction were designed through a specific out-of-sampl…
