Detection of a Spectral Break in the Extra Hard Component of GRB 090926A

We report on the observation of the bright, long gamma-ray burst, GRB 090926A, by the Gamma-ray Burst Monitor and Large Area Telescope (LAT) instruments on board the Fermi Gamma-ray Space Telescope. GRB 090926A shares several features with other bright LAT bursts. In particular, it clearly shows a short spike in the light curve that is present in all detectors that see the burst, and this in turn

Organic farming at local and landscape scales benefits plant diversity

Agri-environment schemes (AES) have been suggested to counter negative effects of agricultural intensification and enhance farmland biodiversity, but evaluations have produced inconsistent results. We suggest that this is partly a consequence of scale-dependence, i.e. that the consequence of organic farming will differ depending on the scale of uptake in a particular landscape. To test our hypothe

Robotic Work-Space Sensing and Control

Industrial robots are traditionally programmed using only the internal joint position sensors, in a sense leaving the robot blind and numb. Using external sensors, such as cameras and force sensors, allows the robot to detect the existence and position of objects in an unstructured environment, and to handle contact situations not possible using only position control. This thesis presents work on

PKC theta/beta and CYLD Are Antagonistic Partners in the NF kappa B and NFAT Transactivation Pathways in Primary Mouse CD3(+) T Lymphocytes

In T cells PKC theta mediates the activation of critical signals downstream of TCR/CD28 stimulation. We investigated the molecular mechanisms by which PKC theta regulates NF kappa B transactivation by examining PKC theta/beta single and double knockout mice and observed a redundant involvement of PKCh and PKC beta in this signaling pathway. Mechanistically, we define a PKC theta-CYLD protein compl

Proteinase 3 and Neutrophil Apoptosis in ANCA-Associated Systemic Vasculitis

Popular Abstract in Swedish Ordet vaskulit betyder kärlinflammation och med systemisk vaskulit menas inflammation i blodkärl på flera olika ställen i kroppen. Vaskulit kan drabba alla typer av kärl i kroppen, både stora och små, artärer, vener och kapillärer. Inflammationen i kärlväggen kan leda till att kärlet skadas och att blodförsörjningen till olika organ då kan bli bristfällig. Symtomen vid ANCA-Associated Systemic Vasculitis (AASV) is characterized by leukocytoclasis- dying neutrophils surrounding small blood vessels. Previous studies have shown increased plasma PR3 and increased proportion of neutrophils expressing plasma membrane-associated PR3 (mPR3+). Neutrophils were isolated by polymorphprep and membrane expression was measured by FACS. Plasma PR3, pro-PR3 and cytokines were

Frequency-Domain Maximum-Likelihood Estimation of High-Voltage Pulse Transformer Model Parameters

This paper presents an offline frequency-domain nonlinear and stochastic identification method for equivalent model parameter estimation of high-voltage pulse transformers. Such kinds of transformers are widely used in the pulsed-power domain, and the difficulty in deriving pulsed-power converter optimal control strategies is directly linked to the accuracy of the equivalent circuit parameters. Th

Higher Plant Calreticulins Have Acquired Specialized Functions in Arabidopsis

Background: Calreticulin (CRT) is a ubiquitous ER protein involved in multiple cellular processes in animals, such as protein folding and calcium homeostasis. Like in animals, plants have evolved divergent CRTs, but their physiological functions are less understood. Arabidopsis contains three CRT proteins, where the two CRTs AtCRT1a and CRT1b represent one subgroup, and AtCRT3 a divergent member.

Civilizing unmarried urban women in China: Authentic or Not?

Aim: The aim of this research was to explore and evaluate the new expected identities of unmarried urban women in China, by analyzing the changes in the marriage law in the last 60 years, particularly in property division in the case of divorce. Methodology: The paper proceeded under the qualitative method and designed a case study in Chengdu. The data from books, journals, policies, newspapers an

Adoption Reasons for Enterprise Systems as a Service - A Recap of Provider Perspectives

In 2003 the concept of Application Service Provision (ASP) as a way to provide Enterprise Systems (ES) to Small and Medium sized Enterprises (SMEs), “hyped”. In 2013 we saw the same “hype” but now with the Software as a Service (SaaS) model. Even if labelled differently, these concepts seem to mean the same and so, in this paper, we explore if providers perspective for the adoption of external pro

Att beforska barn och unga i hem, skola, samhällsvård och kriminalvård

The article describes and analyses the legal framework concerning children’s participation in research in Sweden. Research on children is one way to improve children’s living conditions. For example, there is a need for knowledge about children’s and young people’s situation at home, at school, in community care and in correctional facilities. It is inevitable that there arise both ethical and leg

Accentuation and deaccentuation in Russian – a functional account

The present article is a functional analysis of intonation in Russian declarative utterances. Pragmatically relevant tonal patterns and their functions are identified and described. Utterances are analysed in terms of theme and rheme. Theme is signalled by a tonal rise and rheme by a falling tonal gesture. Beside thematic and rhematic tonal gestures, other rising accents in the utterance are ident

Mechanisms of Dopamine D1 Receptor-Mediated ERK1/2 Activation in the Parkinsonian Striatum and Their Modulation by Metabotropic Glutamate Receptor Type 5.

In animal models of Parkinson's disease, striatal overactivation of ERK1/2 via dopamine (DA) D1 receptors is the hallmark of a supersensitive molecular response associated with dyskinetic behaviors. Here we investigate the pathways involved in D1 receptor-dependent ERK1/2 activation using acute striatal slices from rodents with unilateral 6-hydroxydopamine (6-OHDA) lesions. Application of the dopa

How to Develop Renewable Power in China? A Cost-Effective Perspective

To address the problems of climate change and energy security, Chinese government strived to develop renewable power as an important alternative of conventional electricity. In this paper, the learning curve model is employed to describe the decreasing unit investment cost due to accumulated installed capacity; the technology diffusion model is used to analyze the potential of renewable power. Com

Dynamics of the glomerular filtration barrier - Physiological and pathophysiological aspects

The dynamic properties of the glomerular filtration barrier (GFB) are of fundamental importance for the understanding of the physiology and pathophysiology of microalbuminuria and proteinuric diseases. In the studies of this doctoral thesis the properties of the rat glomerular filtration barrier were investigated under resting conditions and following a number of challenges using highly sensitive

Combined effect of atmospheric nitrogen deposition and climate change on temperate forest soil biogeochemistry: A modeling approach

Atmospheric N deposition is known to severely impact forest ecosystem functioning by influencing soil biogeochemistry and nutrient balance, and consequently tree growth and overall forest health and biodiversity. Moreover, because climate greatly influences soil processes, climate change and atmospheric N deposition must both be taken into account when analysing the evolution of forest ecosystem s

Short-term adaptation during propagation improves the performance of xylose-fermenting Saccharomyces cerevisiae in simultaneous saccharification and co-fermentation.

Inhibitors that are generated during thermochemical pretreatment and hydrolysis impair the performance of microorganisms during fermentation of lignocellulosic hydrolysates. In omitting costly detoxification steps, the fermentation process relies extensively on the performance of the fermenting microorganism. One attractive option of improving its performance and tolerance to microbial inhibitors
