Externa elektriska fält som appliceras på biologiska material interagerar direkt med fria elektriska laddningar som elektroner och joner samt jongrupper i större molekyler. De interagerar också med dipoler såsom vatten och inducerar dipoler i molekyler med polariserbara grupper. Cellmembranerna verkar vara det kritiska målet för interaktion som orsakar intra-molekylära övergångar och intermolekylä

In 2017, the Swedish government published an official report entitled "Att ta emot människor på flykt: Sverige hösten 2015." The report describes how Swedish state agencies, municipalities, and civil society conceptualized and managed the refugee crisis of 2015. This chapter spells out the official public theories expressed in this report and in doing so unfolds two key findings. First, the govern

This thesis is on information dynamics modeled using *dynamic epistemic logic* (DEL). It takes the simple perspective of identifying models with maps, which under a suitable topology may be analyzed as *topological dynamical systems*. It is composed of an introduction and six papers. The introduction situates DEL in the field of formal epistemology, exemplifies its use and summarizes the main cont

The aim of this study is to increase our understanding of the attitudes towards the scientific search for extraterrestrial life among high school and university students in Sweden. The most important results of the analysis are that: (a) the great majority of students believe that extraterrestrial life exists; (b) most students regard searching for extraterrestrial life to be quite important or ve

Hintikka’s "Knowledge and Belief" from 1962 is considered the seminal treatise on epistemic logic. It provides the nuts and bolts of what is now a flourishing paradigm of significance to philosophy, economics, mathematics and theoretical computer science—in theory as well as practice. And in theory and for practice epistemic logic has been extensively articulated, refined and developed especially

To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. However, further price reductions and new innovations are needed for solar cell technology to fulfil

Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor tem- perature. However, this control principle cannot take into account heat gains or losses caused by tenants, electrical appliances, the sun, air leakage, etc., which may result in uneven indoor Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor temperature.

The study primarily draws on genetic structuralism in unraveling social transformations embedded in short stories written by Egyptian authoresses. It also makes use of feminist concepts given that the content in question is written by Egyptian women writers and hence blends general social transformations with those affected by feminism. Four Egyptian authoresses were selected for this study along

Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. Patients

Data representation migration is a program transformation that involves changing the type of a particular data structure, and then updating all of the operations that somehow depend on that data structure according to the new type. Changing the data representation can provide benefits such as improving efficiency and improving the quality of the computed results. Performing such a transformation i

The environment of the Tibetan Plateau (TP) is regarded as one of the most sensitive ecosystems of the world. However, investigations on effects caused by global climate change or anthropogenic activities are rare due to its quite remote location. This thesis deals with various aspects of the carbon and water cycle within ecological and hydrological studies that can be assessed by measurements of

Microfluidics is a field which has the potential to revolutionize medical diagnostics. The ability to sort and analyse cells by the use of portable handheld devices has the potential to enable sensitive devices for point-of-care diagnostics. This could play a major role in diagnosis of a wide range of diseases which are prevalent in remote areas in developing countries where a majority of the peopMicrofluidics is a field which has the potential to revolutionize medical diagnostics.

Xenopus is a favorable experimental model in developmental biology. With its fast and external development, high number of progeny and large size, early embryos are well suited for micromanipulation to study the function of genes with relevance to human diseases. In this chapter, we present a combined method for lineage tracing and whole-mount in situ hybridization. In addition, we present protocoXenopus is a favorable experimental model in developmental biology.
