A correlation for predicting smoke layer temperature in a room adjacent to a room involved in a pre-flashover fire
Advanced fire modelling software have been developed and improved during the last couple of decays and thesekinds of software have been shown to be valuable tools for fire safety engineers. However, the advances made have not replaced the need for simple hand-calculation methods. Simple hand-calculations methods can be used to obtain a first estimate of, for example, smoke layer temperatures in a per
Revised correlation of Silurian Provincial Series of North America with global and regional chronostratigraphic units and delta 13C(carb) chemostratigraphy
Recent revisions to the biostratigraphic and chronostratigraphic assignment of strata from the type area of the Niagaran Provincial Series (a regional chronostratigraphic unit) have demonstrated the need to revise the chronostratigraphic correlation of the Silurian System of North America. Recently, the working group to restudy the base of the Wenlock Series has developed an extremely high-resolut
Optimal controller synthesis for the decentralized two-player problem with output feedback
In this paper, we present a controller synthesis algorithm for a decentralized control problem. We consider an architecture in which there are two interconnected linear subsystems. Both controllers seek to optimize a global quadratic cost, despite having access to different subsets of the available measurements. Many special cases of this problem have previously been solved, most notably the state
Mild Renal Dysfunction and Metabolites Tied to Low HDL Cholesterol Are Associated With Monocytosis and Atherosclerosis
Background-The number of circulating blood monocytes impacts atherosclerotic lesion size, and in mouse models, elevated levels of high-density lipoprotein cholesterol suppress blood monocyte counts and atherosclerosis. We hypothesized that individuals with mild renal dysfunction at increased cardiovascular risk would have reduced high-density lipoprotein levels, high blood monocyte counts, and acc
Human papillomavirus type-specific risk of cervical cancer in a population with high human immunodeficiency virus prevalence: case-control study
There are limited data on human papillomavirus (HPV) type-specific cervical cancer risk among human immunodeficiency virus (HIV)-positive women. Previous studies have suggested that HPV 16 would be relatively less important as a causative agent among HIV-positive compared with HIV-negative women. This study investigates HPV type-specific cervical cancer risk in a population in which HIV is endemic
Destabilizing domains mediate reversible transgene expression in the brain.
Regulating transgene expression in vivo by delivering oral drugs has been a long-time goal for the gene therapy field. A novel gene regulating system based on targeted proteasomal degradation has been recently developed. The system is based on a destabilizing domain (DD) of the Escherichia coli dihydrofolate reductase (DHFR) that directs fused proteins to proteasomal destruction. Creating YFP prot
Rail Tunnel Evacuation
In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. More specifically, a theoretical framework that can aid the understanding of human behavior is identified, and its applicability to rail tunnels is demonstrated. In addition, new empirical data on
A GIS Approach to Evaluating Ecological Sensitivity for Tourism Development in Fragile Environments. A Case Study from SE Iceland
Expansion of tourism in the northern periphery regions provides innovative resources for an economic boost to many of the peripheral communities. The northern ecosystems are however extremely vulnerable. It is therefore of vital importance for such communities to plan the growth of tourism along sustainable lines in order to secure long-term economic benefit from tourism. Geographical Information
Psychometric evaluation of the Swedish language Person-centred Climate Questionnaire - family version
Background: In a holistic view of care, the family is important for the patient as well as for the staff and integration of family members in health care is a growing trend. Yet, family participation in the care is sparsely investigated and valid assessment instruments are needed. Setting: Data were collected from 200 family members participating in an intervention study at an emergency department
Mice Lacking NCF1 Exhibit Reduced Growth of Implanted Melanoma and Carcinoma Tumors.
The NADPH oxidase 2 (NOX2) complex is a professional producer of reactive oxygen species (ROS) and is mainly expressed in phagocytes. While the activity of the NOX2 complex is essential for immunity against pathogens and protection against autoimmunity, its role in the development of malignant tumors remains unclear. We compared wild type and Ncf1 (m1J) mutated mice, which lack functional NOX2 com
Effect of cement type on durability of concrete - results of a cooperative test
Professional caregivers' work with the dying in nursing homes - a Foucault-inspired analysis of discourses in the last decade in a Danish context.
International studies on the death of elderly nursing home residents show the complexity in the understanding of the professionals who care for the dying. The aim of this study is to explore the discourses about professional caregivers caring for those dying in Denmark in the last decade. A discourse analysis inspired by Foucault was constructed. The material consists of different source documents
Situated Transgressiveness: Exploring One Transwoman's Lived Experiences across Three Situated Contexts
This study investigates the lived experience of one transwoman, Claire, a public advocate and a manager with client services responsibilities. We examine Claire's story in order to discuss how situated contexts, such as different roles, locales and interactions, shape the way she experiences and perceives her trans body and gender identity. In particular, our analysis centres on how Claire's lived
Biofuel cell as a power source for electronic contact lenses.
Here we present unequivocal experimental proof that microscale cofactor- and membrane-less, direct electron transfer based enzymatic fuel cells do produce significant amounts of electrical energy in human lachrymal liquid (tears). 100μm diameter gold wires, covered with 17nm gold nanoparticles, were used to fashion three-dimensional nanostructured microelectrodes, which were biomodified with Coryn
Why is Chinese Regional Output Diverging?
In a recent paper Pedroni and Yao (2006) present strong evidence suggesting that Chinese provincial per-capita output is diverging, a result that goes against the Chinese government’s goal of a balanced wealth-creation across provinces. This paper provides an in-depth analysis of the reasoning behind this finding. Our main result is that the divergence does exist, even when new data and more advan
An Altered Phenotype in a Conditional Knockout of Pitx2 in Extraocular Muscle
PURPOSE. To determine the temporal and spatial expression of Pitx2, a bicoid-like homeobox transcription factor, during postnatal development of mouse extraocular muscle and to evaluate its role in the growth and phenotypic maintenance of postnatal extraocular muscle. METHODS. Mouse extraocular muscles of different ages were examined for the expression of Pitx2 by RT-PCR, q-PCR, and immunostaining
Spectral interferences from formaldehyde in CH PLIF flame front imaging with broadband B-X excitation
In this letter we show that the use of slightly broadband laser sources like multimode alexandrite lasers for CH PLIF bears the danger of interferences from formaldehyde. Such interferences occur when the laser frequency is not carefully tuned to the B-X (0,0) R-branch band head at around 387.2 nm and manifest either in the appearance of an additional layer in the PLIF image or in a slight broaden
Markers of Infection in Childhood Autoimmune Diabetes and Related Disorders
Popular Abstract in English The main aim of this thesis was to contribute to the knowledge about mechanisms involved in the development of type 1 diabetes (T1D) and other autoimmune diseases in children. Immune markers in relation to genetic propensity in children with autoimmune disease, mainly T1D and a small group of juvenile idiopathic arthritis (JIA) and thyroiditis (THYR), as well as healthyThe main aim of this thesis was to contribute to the knowledge about mechanisms involved in the development of type 1 diabetes (T1D) and other autoimmune diseases in children. Immune markers in relation to genetic propensity in children with autoimmune disease, mainly T1D and a small group of juvenile idiopathic arthritis (JIA) and thyroiditis (THYR), as well as healthy controls have been studied.
