Selective isolation of lactate dehydrogenase (LDH) from porcine muscle extract was studied using foam generated from the vigorous stirring of a non-ionic surfactant, Triton X-114 derivatized with Cibacron blue. The cloud point of the surfactant-dye conjugate was higher than that of the native Triton X-114, and also the foam prepared from the affinity surfactant was more rigid taking a longer time
In the golden egg bug (Phyllomorpha laciniata Vill. Heteroptera: Coreidae) females lay eggs on the backs of conspecifics, often on courting males. Although the bugs do not provide care to the eggs, this decreases the risk of egg predation. As an effect males carry many eggs which are not their own. The male and female interests are in conflict; females need to find an oviposition site, and male fi
Long-term phenology monitoring has documented numerous examples of changing flowering dates during the last century. A pivotal question is whether these phenological responses are adaptive or not under directionally changing climatic conditions. We use a classic dynamic growth model for annual plants, based on optimal control theory, to find the fitness-maximizing flowering time, defined as the sw
This article takes Italy’s widely-debated 2009 push-backs to Libya campaign as a point of reference to address whether bilateral agreements for technical and police cooperation provide the legal foundation for the forced return of intercepted refugees to countries of embarkation. Through a detailed analysis of both the facts and the texts of the published and unpublished bilateral accords, it conc
Directional swimming in the box jellyfish Tripedalia cystophora (cubozoa, cnidaria) is controlled by the shape of the velarium, which is a thin muscular sheet that forms the opening of the bell. It was unclear how different patterns of visual stimulation control directional swimming and that is the focus of this study. Jellyfish were tethered inside a small experimental tank, where the four vertic
224 patients with undisplaced femoral neck fractures treated with two parallel Hansson hook pins were studied. After a mean follow-up time of 32 months (S.D. 5.2), 15% had a reoperation. 11% were considered failures, mostly avascular necrosis, and 9% had a secondary arthroplasty. Possible risk factors for poor outcome were analysed. Neither high age nor surgical delay was associated with increased
Popular Abstract in Swedish Denna avhandling analyserar frågor som berör tillfälliga jobb på den svenska arbetsmarknaden under perioden 1990-1999. Ett viktigt bidrag i avhandlingen är att den stora gruppen tillfälliga jobb delas upp i mindre undergrupper för att ta i beaktande den heterogenitet som finns mellan olika former av tillfälliga jobb. En röd tråd som löper genom hela avhandlingen är fokuThis thesis analyses different aspects of temporary jobs in the Swedish labour market during 1991-1999. Throughout the thesis we put special focus on differences between the genders, and differences between native-born and foreign-born workers. In chapter 1, An Introduction to Temporary Jobs in Sweden, we describe the evolution of different types of temporary jobs in Sweden during the 1990s, we re
Aims and objectives: The aim of this study was to describe how EL was eased, as narrated by frail older people. Background: Existential loneliness (EL) is an unavoidable part of the human condition. It is a complex phenomenon that has been described as disconnection from life. If EL is acknowledged in the care of older people, the experience of EL can be reduced. Design: In this qualitative study,
This article explores the use of identity politics in conflicts that pertain to land, land restitution and traditional authority in northern KwaZulu-Natal, South Africa, and more specifically the Dukuduku area. Under the influence of past geographic displacements, ongoing neoliberal transformations and the transition to democracy under the post-apartheid government, not least including contested t
In a recent article for this journal, Stuart, D., Gunderson, R., and Petersen, B. [(2017). Climate change and the Polanyian counter-movement: carbon markets or degrowth? New political economy, 1–14. doi:10.1080/13563467.2017.1417364] discuss solutions to climate change in terms of Karl Polanyi’s concept of the double movement. They set up their argument as a critique of my own article on the topic
Biodiversity is challenged worldwide by exploitation, global warming, changes in land use and increasing urbanization. It is hypothesized that communities in urban areas should consist primarily of generalist species with broad niches that are able to cope with novel, variable, fragmented, warmer and unpredictable environments shaped by human pressures. We surveyed moth communities in three cities
In situ studies using transmission electron microscopy (TEM) can provide insights to how properties, structures and compositions of nanostructures are affected and evolving when exerted to heat or chemical exposure. While high-resolved imaging can be obtained continuously, at video-framerates of hundreds of frames per second (fps), compositional analysis struggles with time resolution due to the l
Objective. The aim was to theoretically and experimentally investigate recovery in SPECT images with objects of different shapes. Furthermore, the accuracy of volume estimation by thresholding was studied for those shapes. Approach. Nine spheres, nine oblate spheroids, and nine prolate spheroids phantom inserts were used, of which the six smaller spheres were part of the NEMA IEC body phantom and
What is done in the act of public intelligence disclosures? Leading up to the Russian invasion of Ukraine in 2022, US intelligence agencies engaged in an unprecedented amount of public disclosures, causing scholars and journalists to describe it as a tectonic shift in intelligence practice. Going beyond the traditional question of strategic aims related to intelligence disclosures, this article ta
The system of welcoming newly arrived students in Sweden has experienced numerous modifications since its inception. Additionally, because the interpretation of education laws us left to the municipalities and head teachers, the various policies have resulted in a multitude of local practices. Over the years, a very wide range of models for organising newcomer reception have therefore been tried o
Abstract: Sedan 1990-talet finns en till synes motstridig rörelse inom kulturområdet. Dels en tendens att kultursektorn, i dess nuvarande kulturpolitiskt mer traditionella avgränsning, uppfattas som alltmer marginaliserad. Dels att kultur i bredare bemärkelse efterfrågas i allt högre grad och inom allt fler områden. Rörelsen hänger samman med övergripande samhällsförändringar som globaliseringens Since the 1990s, there has been a seemingly contradictory movement in the field of culture. On the one hand, there is a tendency for the cultural sector, in its current cultural-political more traditional demarcation, to be perceived as increasingly marginalized. Secondly, that culture in a broader sense is in increasing demand and in more areas. The movement is connected with overarching societal
This book offers insights on politics and ethics of representation that are relevant to researchers concerned with struggles for justice. It takes moments of discomfort in the qualitative research process as important sites of knowledge for exploring representational practices in critical research.The Politics and Ethics of Representation in Qualitative Research draws on experiences from research
Models for Non-Modelers focuses not on how to design models but on how to understand and critically appraise them. Data and statistical models are widely used in disciplines such as epidemiology, climate science and systems design, but it can be difficult for those without the necessary training to understand and implement them. This book is for non-modelers, especially social scientists. Through
