Healthcare staff and students have a great risk of developing musculoskeletal symptoms. One cause of this is heavy load related work activities such as manual handling, in which the quality of individual work technique may play a major role. Preventive interventions and well-defined educational strategies to support movement awareness and long-lasting movement changes need to be developed. The aim

This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct with relevance for tip cooling of gas turbine blades. The U-duct models the internal blade cooling flow passages. Both friction factors and convective heat transfer coefficients were measured along the bend (turn) part of the U-duct for three different rib configuration cases, namely (a)

Scoliosis is an S-shaped sideways curvature of the spine leading to the shape change of the torso Idiopathic scoliosis is one form of this disease with unknown aetiology. 300 children out of 100 000 need treatment. Treatment duration is till the end of the patient’s growth age (till the ossification of the skeleton) and the brace should be worn 23 hours a day. Problems with brace are: heat, moist,

A highly optimized Monte Carlo (MC) code package for simulating light transport is developed on the latest graphics processing unit (GPU) built for general-purpose computing from NVIDIA - the Fermi GPU. In biomedical optics, the MC method is the gold standard approach for simulating light transport in biological tissue, both due to its accuracy and its flexibility in modelling realistic, heterogen

Photosystem II utilizes solar energy to drive electrons from the Mn cluster at the lumenal side to the quinone at the stromal side of the thylakoid membrane. The source of electrons is H2O, which is split to oxygen by the OEC. The water-splitting process involves cycling of the Mn-cluster through four semi-stable oxidation states, termed the S0, S1, S2, and S3 states. The OEC can be trapped in the

Popular Abstract in Swedish Denna avhandling presenterar några reglertekniska tillämpningar i elkraftsystem. Tillämpningarna är: hur likströmskablar påverkar båtrafik som använder magnetkompasser; frekvensmätning i elkraftsystem; algorithmer för datorbaserade reläskydd; koppling av aktiv last för att dämpa effektpendlingar.This thesis presents some control applications in electric power systems. The work consists of the four parts: interaction between DC cables and ship steering autopilots; frequency estimation; computer relaying; field tests using load switching to damp power oscillations. The first three parts are based on four papers that are given in Appendix A-D. The thesis presents supplementary text to these

It was recently shown that prostacyclin at a low dose reduces cortical cell death following brain trauma in the rat. Conceivably, prostacyclin with its vasodilatory, anti-aggregatory, anti-adhesive and permeability-reducing properties improved a compromised perfusion caused by post-traumatic vasoconstriction, microthrombosis and increased microvascular permeability. The objective of the present st
