Laminar burning velocities, S-L, of ethane + air and propane + air flames within an equivalence ratio range between 0.8 and 1.3 were determined at atmospheric and elevated pressures up to 4 atm. Measurements were performed in non-stretched flames, stabilized on a perforated plate burner at adiabatic conditions, created using the heat flux method. Initial unburnt gas temperature was 298 K. These ne

Insulin Dependent Diabetes Mellitus (IDDM) is a chronic disease characterized by the inability of the pancreas to produce sufficient amounts of insulin. Daily compensation of the deficiency requires 4-6 insulin injections to be taken daily, the aim of this insulin therapy being to maintain normoglycemia- i.e., a blood glucose level between 4-7 mmol/L. To determine the quantity and timing of these

Background and purpose The Scandinavian Sarcoma Group (SSG) XIV protocol was based upon the organisations experience from 3 previous osteosarcoma trials and was considered best standard of care for patients with extremity localised, non-metastatic osteosarcoma. We report the outcome of this protocol. Patients and methods From March 2001 to April 2005, 63 patients recruited from 10 centres in Finla

INTRODUCTION: Sex steroids are important for growth and maintenance of the skeleton. Catechol-O-methyltransferase (COMT) is an estrogen degrading enzyme. The COMT val158met polymorphism results in a 60-75% difference in enzyme activity between the val (high activity=H) and met (low activity=L) variants. We have previously reported that this polymorphism is associated with bone mineral density (BMD

Over the last few years we have seen a rapidly increasing interest in the functions of the inhibitory interneurons of the cerebellar cortex. However, we still have very limited knowledge about their physiological properties in vivo. The present study provides the first description of their spontaneous firing properties and their responses to synaptic inputs under non-anesthetized conditions in the

Semi-terrestrial tardigrades are well-known for their tolerance to a variety of environmental extremes, including desiccation, freezing and radiation. Despite several attempts to reveal the genetic and molecular mechanisms behind the resilience of tardigrades, it is still unknown how these animals are able to maintain the integrity of their cellular components under severe stress. Quantitative or

Exposure to ultrafine particles (UFP) may have adverse health effects. Central monitoring stations do not represent the personal exposure to UFP accurately. Few studies have previously focused on personal exposure to UFP. Sixty non-smoking residents living in Copenhagen, Denmark were asked to carry a backpack equipped with a portable monitor, continuously recording particle number concentrations (

Objective. To estimate the incidence of dystocia among nulliparous women without apparent co-morbidity and to examine maternal and fetal short-term outcomes after dystocia. Design. A multi-center cohort study with prospectively collected data. Setting. Nine obstetric departments with annual birth rates between 850 and 5,400. Population. Low-risk nulliparous women in term spontaneous labor with a s

Ambulanssjukvård är en verksamhet som under de senaste decennierna successivt ombildats från att huvudsakligen transportera patienter till vårdinrättningar till att idag vara en viktig vårdgivande aktör i mobiliseringen av prehospital akutsjukvård. För att ambulanspersonal ska kunna uppfylla deras utökade arbetsuppgifter och bibehålla god patientsäkerhet i takt med ökade påfrestningar på hela ambuThe operations of emergency medical services have in the past few decades undergone a transformation from mainly transporting patients to health facilities to being a key care-giving contributor in the mobilization of prehospital care. In order for paramedics to fulfill their expanded set of tasks while maintaining good patient safety concurrently with increasing demands on the emergency medical s

This thesis investigates how cooperative membership impacts on the well-being of the individual. The case of the umbrella cooperative El Ceibo, operating in Bolivia, is investigated. Organizations such as the UN, the World Bank, and the ILO have high hopes for agricultural cooperatives as partners in the struggle for rural development. However, there is a lack of empirical studies investigating th

Remote sensing is an extensively used technique in ecosystem monitoring or analyzing the carbon balance on the earth surface. The most dominant part of south west Skåne is agricultural land and MODIS derived Vegetation Indexes (VIs) are able to investigate the seasonality of crop fields. The values of VIs represent the different stages of spring greening up of crops and it shows the non-linear and

Introduction: Patients with severe haemophilia A (HA) with no family history of haemophilia will be diagnosed upon their first bleeding event. Methods: Herein, we studied the effects of lack of family history in HA and the subsequent delay of diagnosis on bleeding pattern and early treatment, as well as on the risk of inhibitor development. For this purpose, data on 1237 severe HA patients with kn

Teams are dynamic systems that develop, adapt, and change as members interact and respond to their environments. Theory in organizational research emphasizes that team phenomena are multilevel, temporal, and often nonlinear. Yet, the statistical methods commonly used to study teams have lagged behind these theoretical advances, limiting empirical progress. This dissertation addresses this methodol

A NNW-trending mafic dyke from the central-western Bastar craton yields a U[sbnd]Pb ID-TIMS baddeleyite age of 1944 ± 6 Ma. By correlating additional dykes with similar trend and geochemical characteristics, we identify a previously unrecognized dyke swarm, named herein the Pakhanjore swarm. Geochemical evidence suggests that the studied rocks are derived from partial melting of a spinel-rich, sha

In this paper, the model of moral motivation as developed by Brekke et al (2003) is analysed with the new assumption that self-image is an increasing function of effort. While the effects of increased efficiency and new information on optimal effort levels are largely similar, different results are obtained when individuals are faced with responsibility and economic incentives. Following Brekke et

Informal employment in the 21st century is increasingly prevalent across the world and becomes particularly insecure in the Global South. This thesis studies different aspects of the precarious nature of informal sector jobs in a specific district in India. The research is built upon the concept of precarity which refers to instability, vulnerability and the volatile essence of the informal labor

This study challenges existing dogma of economists and environmentalists with a finding that sustainable consumption in industrial societies is impossible within standard models of growth because the approaches that are being taken to investments (in new technologies) are linked with and dependent on increased consumption as a requirement of innovation and as part of ideology in societies. Though

Denna rapport är ett resultat av ett examensarbete som undersöker hur RFID-teknologi kan användas vid leveranser av prefabricerade betongelement för att på så sätt få en ökad kontroll och ett optimerat flöde av dessa leveranser till och på en byggarbetsplats.

RFID är en förkortning för Radio Frekvens Identifiering och är ett system som möjliggör informationsöverföring mellan en tagg, även

This paper analyzes mortality, cancer recurrence (loco-regional, other types of cancer and distant) and the impact of progesterone status on the effect of Tamoxifen using survival analysis methods. The data consists of 258 postmenopausal women from the Southern Sweden health care region with estrogen positive receptor status receiving radiotherapy, Tamoxifen and a combination of those after mastect
