Many-body depletion forces of colloids in a polydisperse polymer dispersant in the long-chain limit

We study a system of spherical non-adsorbing particles immersed in a polydisperse polymer fluid. We derive an analytic expression for the many-body depletion interactions between the colloidal particles in the limit of very long chains. We argue that this expression is essentially exact for long chains and justify this using explicit simulations. In this way we are able to elucidate the profound e

Akademien är inte så privat som den tror

I förra veckan antog Svenska Akademien en ny kommentar till sina stadgar. Där menade man att det ligger närmast till hands att jämföra Akademien med privaträttsliga organisationer. Men frågan är om man inte borde ha jämfört sig mer med de statliga institutionerna.

CCL21 as a Potential Serum Biomarker for Pulmonary Arterial Hypertension in Systemic Sclerosis

Objective: Systemic sclerosis (SSc) is a major cause of pulmonary arterial hypertension (PAH). Murine models indicate key roles for chemokines CCL19 and CCL21 and their receptor CCR7 in lung inflammation leading to PAH. The objective of this study was to assess the chemokine CCL19–CCL21 axis in patients with SSc-related PAH. Methods: Serum samples obtained from 2 independent prospective SSc cohort

Kampen för rättsstaten

Martin Sunnqvist reflekterar över olika aspekter som rör rättsstaten. Hur byggs en rättsstat upp? Hur bryts en rättsstat ned? Den första frågan har lett till att fri- och rättigheter, oavhängiga domstolar, författningsdomstolar och självständiga advokatväsenden har införts i många länder. Nu måste den motsatta frågan ställas, så att varningsklockorna kan identifieras.

OSL dating of Weichselian ice-free periods at Skorgenes, western Norway

During recent years, many sites with sediments pre-dating the Last Glacial Maximum have been identified in formerly glaciated areas. As more and better dates are presented from these sites, the dynamic behaviour of the Scandinavian Ice Sheet is becoming increasingly clear. In this study, we revisited the site Skorgenes in western Norway. Here, sediments from two ice-free periods are found below an

Morphological and phylogenetic aspects of the dentition of Megacephalosaurus eulerti, a pliosaurid from the Turonian of Kansas, USA, with remarks on the cranial anatomy of the taxon

Megacephalosaurus eulerti is a large macropredatory plesiosaur representing one of the last members of the diverse pliosaurid clade Brachaucheninae. The taxon was established upon a nearly complete skull including the mandible and fragments of the postcranial skeleton originating from the lower middle Turonian (Upper Cretaceous) of Kansas, USA. Owing to its age, reasonable completeness and its sta

Temporal relationship of sleep apnea and acromegaly : a nationwide study

Purpose: Patients with acromegaly have an increased risk of sleep apnea, but reported prevalence rates vary largely. Here we aimed to evaluate the sleep apnea prevalence in a large national cohort of patients with acromegaly, to examine possible risk factors, and to assess the proportion of patients diagnosed with sleep apnea prior to acromegaly diagnosis. Methods: Cross-sectional multicenter stud

Foreign Investment in Agricultural Development : The Past of the Present in Zambia

This study grounds a highly charged debate on agriculture in developing countries within economic theory, by establishing a structured analytical framework for considering the potential role of foreign investment in supporting agricultural development. The framework is developed to be time and space neutral, such that it can be utilized in various geographic settings and across different time peri

An integrative transcriptome analysis reveals a functional role for thyroid transcription factor-1 in small cell lung cancer

Small cell lung cancer (SCLC) is a neuroendocrine tumour that exhibits rapid growth and metastatic spread. Although SCLC represents a prototypically undifferentiated cancer type, thyroid transcription factor-1 (TTF-1, gene symbol NKX2-1), a master regulator for pulmonary epithelial cell differentiation and lung morphogenesis, is strongly upregulated in this aggressive cancer type. The aim of this

TomoWarp2 : A local digital volume correlation code

TomoWarp2 is a Python based code that allows full-field vector displacements to be measured between 2D or 3D image sets, based on a local approach of Digital Image Correlation. These displacements can be used to calculate the complete 2D or 3D strain tensor field to study, for example, heterogeneous deformation responses of materials during loading. The code is provided with a GUI, and can handle

Delayed Gadolinium-Enhanced MRI of Menisci and Cartilage (dGEMRIM/dGEMRIC) in Obese Patients With Knee Osteoarthritis : Cross-Sectional Study of 85 Obese Patients With Intra-articular Administered Gadolinium Contrast

Background: Early cartilage changes in knee osteoarthritis (OA) can be assessed by both intravenous (i.v.) and intra-articular (i.a.) delayed gadolinium-enhanced MRI of cartilage (dGEMRIC). Purpose: To examine the relationship between i.a. dGEMRIC and delayed gadolinium-enhanced MRI of menisci (dGEMRIM), and to investigate if the approach can be used to assess the morphological degeneration of men

Development of a Novel Global Surgery Course for Medical Schools

Objective: We endeavored to create a comprehensive course in global surgery involving multinational exchange. Design: The course involved 2 weeks of didactics, 2 weeks of clinical rotations in a low-resource setting and 1 week for a capstone project. We evaluated our success through knowledge tests, surveys of the students, and surveys of our Zimbabwean hosts. Setting: The didactic portions were h

Membrane processes for protein recovery: Present and future

The success of membrane technology in the food industry is directly linked to the success of membranes in protein recovery. Proteins are one of the most important food ingredients and their global market is growing rapidly. In 2012 the global market of protein accounted for 19 billion USD, while for 2018 it is expected to reach 28 billion USD. The aim of this presentation is to provide an overview

Changing an industry with membrane technology – Converting pulp mills to bio-refineries

The pulp and paper industry is one of the most important industrial sectors worldwide and has a great potential to be the nucleus for the future bio-economy. Today’ pulp industry is mainly focusing on the production of cellulose fibres and electricity, while its future potential includes the production of bio-chemicals, bio-fuels and advanced materials. In order to fulfil their future role, pulp m

Fouling and cleaning in the food and bioprocess industry: Key aspects in membrane plant operation

1. INTRODUCTIONFrom the early days of membrane technology fouling has been identified as the most important parameter for the slow integration of technology in the industry [1]. Since then significant progress has been achieved in the field of fouling and cleaning of membranes which are still both key aspects in membrane plant operation in the food and bioprocess industry with a significant impact

Den fysiska butiken i framtiden: Hur kan hållbarhet och digitalisering kombineras för ökat konsumentvärde?

De senaste åren har det blivit tydligt att detaljhandeln av idag måste hantera två förändringstryck: ökande internethandel och hållbarhetshänsyn. Hur fristående fysiska butiker och kedjor hanterar dessa tryck kommer att få avgörande betydelse för deras överlevnad. I detta kapitel argumenteras för att det finns en framtid för den fysiska butiken om miljöhänsyn tas på allvar ihop med de möjligheter

An Autocracy of Empathy : Human-Animal Relations and the Emotional Architecture of Speciesism

With a commitment to a relational ontology, scholars from within the feminist care tradition of animal ethics have been able to theorize how our moral significance - as well as our moral obligations to others - arise from the metaphysical and empathetic 'entanglements. Independent of species, gender and the like, we exist as embodied beings. Sharing a position that originates in nonwestern culture
