Extended physical education in children aged 6-15 years was associated with improved academic achievement in boys

Aim: Physical activity (PA) has been associated with enhanced cognition, brain development and concentration. This study evaluated whether increased physical education (PE) improved academic achievement. Methods: We recruited 304 children (55% boys) from a Swedish school in Skane County in 1998-2002 when they were six to seven years of age and followed them through all nine mandatory school years.

Comparing two methods to record maximal voluntary contractions and different electrode positions in recordings of forearm extensor muscle activity : Refining risk assessments for work-related wrist disorders

BACKGROUND: Wrist disorders are common in force demanding industrial repetitive work. Visual assessment of force demands have a low reliability, instead surface electromyography (EMG) may be used as part of a risk assessment for work-related wrist disorders. For normalization of EMG recordings, a power grip (hand grip) is often used as maximal voluntary contraction (MVC) of the forearm extensor mu

Striatal changes in Parkinson disease : An investigation of morphology, functional connectivity and their relationship to clinical symptoms

We sought to investigate morphological and resting state functional connectivity changes to the striatal nuclei in Parkinson disease (PD) and examine whether changes were associated with measures of clinical function. Striatal nuclei were manually segmented on 3T-T1 weighted MRI scans of 74 PD participants and 27 control subjects, quantitatively analysed for volume, shape and also functional conne

Lessons learned from the 1-hour post-load glucose level during OGTT : Current screening recommendations for dysglycaemia should be revised

This perspective covers a novel area of research describing the inadequacies of current approaches for diagnosing dysglycaemia and proposes that the 1-hour post-load glucose level during the 75-g oral glucose tolerance test may serve as a novel biomarker to detect dysglycaemia earlier than currently recommended screening criteria for glucose disorders. Considerable evidence suggests that a 1-hour

Effects of Pay-For-Performance on Prescription of Hypertension Drugs among Public and Private Primary Care Providers in Sweden

This study exploits policy reforms in Swedish primary care to examine the effect of pay-for-performance (P4P) on compliance with hypertension drug guidelines among public and private health care providers. Providers in regions with P4P are compared to providers in other regions in a difference-in-differences analysis using data from the Swedish Prescription Register for the period 2005-2013. The r

Domain-Informed Signal Processing with Application to Analysis of Human Brain Functional MRI Data

Standard signal processing techniques are implicitly based on the assumption that the signal lies on a regular, homogeneous domain. In practice, however, many signals lie on an irregular or inhomogeneous domain. An application area where data are naturally defined on an irregular or inhomogeneous domain is human brain neuroimaging. The goal in neuroimaging is to map the structure and function of t

Phase behavior in the biologically important oleic acid/sodium oleate/water system

The phase behavior in the oleic acid/sodium oleate/normal saline (0.15 M NaCl aqueous solution) system has been determined. For this purpose visual inspection of samples between crossed polarizers, and Small Angle X-ray diffraction was used to identify the various phases and their unit cell dimensions. A rich phase behavior was observed for the ternary system, featuring reverse micellar, micellar

Gasoline PPC: A parametric study of late cycle mixing conditions using a predictive two-zone SRM modeling tool

The relatively new combustion concept known as partially premixed combustion (PPC) has high efficiency and low emissions. However, there are still challenges when it comes to fully understanding and implementing PPC. Thus a predictive combustion tool was used to gain further insight into the combustion process in late cycle mixing. The modeling tool is a stochastic reactor model (SRM) based on pro

Dynamic Refugee Matching

Asylum seekers are often assigned to a locality in their host country directly upon arrival based on some type of uninformed dynamic matching system which does not take the background of the asylum seekers into consideration. This paper proposes an informed, intuitive, easy-to-implement and computationally efficient dynamic mechanism for matching asylum seekers to localities. This mechanism can be

Histories of land : Politicization, property and belonging in Molo, Kenya

Den här avhandlingen syftar till att utforska politiseringen av mark på lokal nivå i Kenya. Avhandlingen visar hur tillgång till mark legitimeras via berättelser om egendom (property) och tillhörighet (belonging). Begreppet djup politik (deep politics) används för att visa hur de här berättelserna inte bara förändrar synen på mark utan också synen på politik.De empiriska kapitlen beskriver hur staThis thesis aims to explore the politicization of land in a local setting in Kenya. The purpose is to study how access to land is justified through histories about relational property and belonging. The notion of deep politics is used in order to suggest that these histories of property and belonging not only transform the meanings of land but also the meanings of politics.The empirical chapters d

Development of a 3-dimensional tissue lung phantom of a preterm infant for optical measurements of oxygen—Laser-detector position considerations

There is a need to further improve the clinical care of our most vulnerable patients—preterm infants. Novel diagnostic and treatment tools facilitate such advances. Here, we evaluate a potential percutaneous optical monitoring tool to assess the oxygen and water vapor content in the lungs of preterm babies. The aim is to prepare for further clinical studies by gaining a detailed understanding of h

High levels of mitochondrial DNA are associated with adolescent brain structural hypoconnectivity and increased anxiety but not depression

Background: Adolescent anxiety and depression are highly prevalent psychiatric disorders that are associated with altered molecular and neurocircuit profiles. Recently, increased mitochondrial DNA copy number (mtDNA-cn) has been found to be associated with several psychopathologies in adults, especially anxiety and depression. The associations between mtDNA-cn and anxiety and depression have not,

Intermediate prognosis in metastatic germ cell tumours—outcome and prognostic factors

Background: For metastatic germ cell tumour patients with intermediate prognosis (IPGCT) according to the IGCCCG classification 5-year overall survival (OS) rates of 79% were described, but recent data suggest significant changes. Patients and methods: To compare the outcome of current IPGCT with former patients and to find new prognosticators a retrospective observational study was performed. Eli

Action in Mind : A Neural Network Approach to Action Recognition and Segmentation

Recognizing and categorizing human actions is an important task with applications in various fields such as human-robot interaction, video analysis, surveillance, video retrieval, health care system and entertainment industry.This thesis presents a novel computational approach for human action recognition through different implementations of multi-layer architectures based on artificial neural net

A randomised study of tailored toxicity-based dosage of fluorouracil-epirubicin-cyclophosphamide chemotherapy for early breast cancer (SBG 2000-1)

Study aim: Retrospective studies have demonstrated a worse outcome in breast cancer patients not developing leukopenia during adjuvant chemotherapy. The SBG 2000-1 is the first randomised trial designed to compare individually dosed chemotherapy without G-CSF support based on grade of toxicity to standard-dosed chemotherapy based on body surface area (BSA). Methods: Patients with early breast canc
