The challenges for creating a greener economy and the institutional framework for sustainable development pass necessarily, or mostly, through cities, as they concentrate a large and growing part of the world’s economy and population, as well as decision-making power. With the processes of urbanization and rural-urban transformation, the economy in cities, especially in cities of developing countr

I bokens åttonde kapitel relaterar Gregor Noll bokens tema om nya säkerhetshot till den aktuella frågan om EU:s hantering av flyktingar och asylsökande. Kapitlets tes är att EU:s invandrings- och asylpolitik ytterst utgör en protektionistisk ordning med utgångspunkt i nationalstatens kontrollbehov. Noll menar att denna ordning manifesterade sig redan vid unionens tillkomst under femtiotalet. De nu

In this paper, we describe the commutant of an arbitrary subalgebra A of the algebra of functions on a set X in a crossed product of A with the integers, where the latter act on A by a composition automorphism defined via a bijection of X. The resulting conditions which are necessary and sufficient for A to be maximal abelian in the crossed product are subsequently applied to situations where thes

The value of bone mineral density (BMD) measurements to stratify fracture probability can be enhanced in a case-finding strategy that combines BMD measurement with independent clinical risk indicators. Putative risk indicators include age and gender, BMI or weight, prior fracture, the use of corticosteroids, and possibly others. The aim of the present study was to develop a mathematical framework

With the growing possibilities in genetic testing, the number of genetic disorders associated with dystonia has constantly increased over the last few years. Accurate phenotyping is crucial to guide and interpret genetic analyses in the search for an etiological diagnosis. Although eye movements examination has proven a valuable tool in the assessment of patients with inherited movement disorders

Attempts to use colloid science concepts to better understand the dynamic properties of concentrated or crowded protein solutions are challenging due to the fact that globular proteins generally have heterogeneous surfaces that result in anisotropic or patchy contributions to their interaction potential. This is particularly difficult when targeting non-equilibrium transitions such as glass and ge

Sweden is a country that prides itself on its mining tradition, contributions to European self-sufficiency and, more recently, its steel transition. It focuses its greening efforts on decarbonizing and automating the steel industry. Meanwhile, destructive impacts on land and biodiversity are largely overlooked. Drawing on the literature on extractivism and on psychoanalytical conceptual literature

A detailed analysis of the positive parity levels in odd iridium isotopes is carried out with an extended version of the Hecht and Satchler model. A satisfactory description of187-193Ir positive parity states and their electromagnetic properties is obtained by coupling several Nilsson particle configurations to an asymmetric rotor.

Rates of molecular, phenotypic, and lineage diversification typically scale negatively with time interval of measurement, raising longstanding questions about time-dependency of evolutionary processes. These patterns and their potential meaning have recently re-entered evolutionary discussions. In this Perspective, we revisit the general challenges in interpreting rate–time relationships. Much app

We demonstrate the construction and utilization of an affordable apparatus using readily available materials to accurately measure in a quantitative manner the wavelengths reflected by a compact disc (CD) under skimming light rays. In fact, only a limited number of wavelengths can be revealed when light rays from a white lamp are directed at a CD (or a DVD) in a manner that specifically selects th

Organic-inorganic heterostructures play a pivotal role in modern electronic and optoelectronic applications including photodetectors and field effect transistors, as well as in solar energy conversion such as photoelectrodes of dye-sensitized solar cells, photoelectrochemical cells, and in organic photovoltaics. To a large extent, performance of such devices is controlled by charge transfer dynami

A depersonalization episode occurred unexpectedly during an electroencephalogram (EEG) recording for a study.Experience reports tracked the time course of this event and, in conjunction, with EEG data, were analyzed. Thesource activity across canonical frequency bands was analyzed across four periods ended by retrospectiveexperience reports (depersonalization was reported in the 2nd period). Delta

α-Galactosidase (EC 3.2.1.22) and β-mannosidase (EC 3.2.1.25) participate in the hydrolysis of complex plant saccharides such as galacto(gluco)mannans. Here we report on the cloning and characterization of genes encoding an α-galactosidase (AglC) and a β-mannosidase (MndA) from Aspergillus niger. The aglC and mndA genes code for 747 and 931 amino acids, respectively, including the eukaryotic signa

Study Design. This article describes the development of a musculoskeletal model of the human lumbar spine with focus on back muscles. It includes data from literature in a structured form. Objective. To review the anatomy and biomechanics of the back muscles related to the lumbar spine with relevance for biomechanical modeling. Summary of Background Data. To reduce complexity, muscle units have be

Article about the Latvian-American artist Boris Lurie, the art movement NO!art, founded by Lurie, Sam Goodman and Stanley Fischer in 1959 in New York, and the reception history of Lurie and NO!art from the 1960s until today. Accompanied by an extensive interview with Boris Lurie.

We present and analyze low-rank channel estimators for orthogonal frequency-division multiplexing (OFDM) systems using the frequency correlation of the channel. Low-rank approximations based on the discrete Fourier transform (DFT) have been proposed, but these suffer from poor performance when the channel is not sample spaced. We apply the theory of optimal rank-reduction to linear minimum mean-sq

The aim of the thesis is to improve the initial steps of xylose metabolism in recombinant Saccharomyces cerevisiae. S. cerevisiae takes up xylose of poor affinity by means of hexose transporters. Metabolic control analysis was used to investigate whether the low xylose utilisation rate is due to inefficient transport. Xylose transport was found to have little control over the aerobi
