An Approach for Modelling Interdependent Infrastructures in the Context of Vulnerability Analysis

Technical infrastructures of the society are becoming more and more interconnected and interdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Disturbances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly important

Reliability and vulnerability analyses of critical infrastructures: Comparing two approaches in the context of power systems

Society depends on services provided by critical infrastructures, and hence it is important that they are reliable and robust. Two main approaches for gaining knowledge required for designing and improving critical infrastructures are reliability analysis and vulnerability analysis. The former analyses the ability of the system to perform its intended function; the latter analyses its inability to

Effects of diabetes definition on global surveillance of diabetes prevalence and diagnosis: a pooled analysis of 96 population-based studies with 331288 participants

Background Diabetes has been defined on the basis of different biomarkers, including fasting plasma glucose (FPG), 2-h plasma glucose in an oral glucose tolerance test (2hOGTT), and HbA(1c). We assessed the effect of different diagnostic definitions on both the population prevalence of diabetes and the classification of previously undiagnosed individuals as having diabetes versus not having diabet

Continuous-Time Delta-Sigma Modulators for Wireless Communication

The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. Paper I analyses the performance degradation of d

Associations of sex, anthropometric and reproductive factors with clinicopathological and molecular characteristics of colorectal cancer

Colorectal cancer (CRC) is the third most common cancer globally, with approximately 1.2 million new cases every year. The highest incidence rates are seen in developed countries, thereby imposing dietary and lifestyle factors in the etiology of CRC. Accumulating epidemiological evidence suggests that obesity is a risk factor for CRC in particular in men, as weak or no associations are seen in wom

Content and Distribution of Short-Chain Fatty Acids in the Hindgut of Rats Fed Various Sources of Indigestible Carbohydrates

There is increasing evidence that short-chain fatty acids (SCFA) formed by colonic fermentation of indigestible carbohydrates have beneficial physiological effects. Butyric acid is the main energy substrate for the colonic mucosa and has been implicated as important in the prevention and treatment of diseases of the colonic mucosa, such as distal ulcerative colitis and cancer. Propionic acid, on t

From Crew Resource Management to Operational Resilience

This paper questions the correspondance between resilience engineering theory and the theoretical fundaments of traditional CRM training, with its related behavior assessments. Reviewing the theoretical roots of CRM it is concluded that such concepts are rather founded in the information processing paradigm hiding the complexities of adaption to rapidly changing situations. An alternative approach

Societal consequences of critical infrastructure vulnerabilities: integrating power system and regional inoperability input-output models

Critical infrastructures provide indispensable services to society and extensive disruption of these give rise to large societal consequences. Most risk-related studies of critical infrastructures, however, focus rather narrowly on the direct consequences, e.g. expressed by services not supplied or cost of nonsupplied services. Although these measures might serve as a proxy for the direct societal

Comparison of vulnerability and reliability analysis of technical infrastructures

The society depends on reliable and robust services provided by technical infrastructures for its function. The impact of large-scale outages due to the inherent vulnerabilities of technical infrastructures has been demonstrated, for example, by the power outage in the U.S. in 2003 and the power outages in Sweden due to the storms Gudrun in January 2005 and Per in January 2007. Two of the main app

Frequency determination of rare populations by flow cytometry: A hematopoietic stem cell perspective.

Flow cytometry allows for identification of cellular subsets based on cell intrinsic properties, most often by the use of fluorochrome-conjugated antibodies recognizing distinct cell-surface epitopes that define the cells of interest. Advances in technical instrumentation and the availability of an ever-increasing number of fluorophores, today enables identification of multicolor defined cellular

Ovarian size and vascularization as assessed by three-dimensional grayscale and power Doppler ultrasound in asymptomatic women 20-39 years old using combined oral contraceptives

Background: The aim of this study is to estimate ovarian volume, number and volume of antral follicles, and ovarian power Doppler vascular indices as assessed by three-dimensional (3D) transvaginal grayscale and power Doppler ultrasound in women using combined oral contraceptives (COC). Study Design: Two hundred thirteen gynecologically asymptomatic women 20-39 years old using COC were examined wi

Menstrual cycle characteristics in fertile women from Greenland, Poland and Ukraine exposed to perfluorinated chemicals: a cross-sectional study

Does perfluorooctane sulfonate (PFOS) and perfluorooctanate (PFOA) exposure disrupt the menstrual cyclicity? The female reproductive system may be sensitive to PFOA exposure, with longer menstrual cycle length at higher exposure. PFOS and PFOA are persistent man-made chemicals. Experimental animal studies suggest they are reproductive toxicants but epidemiological findings are inconsistent. A cros

InAs nanowire MOSFETs in three-transistor configurations: single balanced RF down-conversion mixers.

Integration of III-V semiconductors on Si substrates allows for the realization of high-performance, low power III-V electronics on the Si-platform. In this work, we demonstrate the implementation of single balanced down-conversion mixer circuits, fabricated using vertically aligned InAs nanowire devices on Si. A thin, highly doped InAs buffer layer has been introduced to reduce the access resista

Nanoconfined Circular and Linear DNA: Equilibrium Conformations and Unfolding Kinetics

Studies of circular DNA confined to nanofluidic channels are relevant both from a fundamental polymer-physics perspective and due to the importance of circular DNA molecules in vivo. We here observe the unfolding of confined DNA from the circular to linear configuration as a light-induced double-strand break occurs, characterize the dynamics, and compare the equilibrium conformational statistics o

The number and characteristics of prevalent vertebral fractures in elderly men are associated with low bone mass and osteoporosis.

We sought to determine whether specific characteristics of vertebral fractures in elderly men are associated with low bone mineral density (BMD) and osteoporosis. Mister osteoporosis Sweden is a population based cohort study involving 3014 men aged 69 to 81 years. Of these, 1427 had readable lateral radiographs of the thoracic and lumbar spine. Total body (TB) BMD (g/cm²) and total right hip (TH)

Generation and characterization of stable, highly concentrated titanium dioxide nanoparticle aerosols for rodent inhalation studies

The intensive use of nano-sized titanium dioxide (TiO2) particles in many different applications necessitates studies on their risk assessment as there are still open questions on their safe handling and utilization. For reliable risk assessment, the interaction of TiO2 nanoparticles (NP) with biological systems ideally needs to be investigated using physico-chemically uniform and well-characteriz
