Cells and organelles are small units for biochemical synthetic purposes, often the smallest practically feasible unit since they contain coenzyme regenerating system, ordered enzyme sequences, etc.These volumes, besides giving some insight into basic technology (immobilisation procedures, etc.), also sum up the current know-how in this subject area and try to predict some future trends. The term i

A technique for the characterisation of droplet aerosols is presented and theoretically evaluated. The system, which finds applications for example in the experimental study of cloud formation and cloud water chemistry, relies on a four-step process. The droplet aerosol is electrically charged in a unipolar charging unit, followed by diffusion drying of the droplets, resulting in charged particles

During March and April of 1995 a major international field project was conducted at the UMIST field station site on Great Dun Fell in Cumbria, Northern England. The hill cap cloud which frequently envelopes this site was used as a natural flow through reactor to examine the sensitivity of the cloud microphysics to the aerosol entering the cloud and also to investigate the effects of the cloud in c

In this study, a sampling and analysis tool for aerosol particles has been developed. Its purpose is to characterize upper tropospheric aerosols, where concentrations are low. Since measurements will be made from an airplane, a time resolution of one hour is desirable. These conditions require efficient sampling and analysis with low detection limits. To accomplish this, our sampler uses impaction

Tillgång till pollinerare är avgörande för produktionen av många grödor. Det är viktigt att känna till olika insektsarters egenskaper och att skapa förutsättningar för en mångfald av pollinerare. Det kan i vissa situationer uppstå risk för konkurrens mellan vilda bin och honungsbin.

Prolonged intake of excessive amounts of ethanol is known to have adverse effects on the central nervous system (CNS). Here we investigated the effects of acute and chronic ethanol exposure and withdrawal from chronic ethanol exposure on glymphatic function, which is a brain-wide metabolite clearance system connected to the peripheral lymphatic system. Acute and chronic exposure to 1.5 g/kg (binge

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, generates a large amount of waste heat. Some of this heat is partially recovered and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This work studies in detail four different solutions to utilize t

AIMS/HYPOTHESIS: Finding new treatment alternatives for individuals with diabetes with severe insulin resistance is highly desired. To identify novel mechanisms that improve glucose uptake in skeletal muscle, independently from insulin levels and signalling, we have explored the therapeutic potential of a short peptide sequence, RG54, derived from apolipoprotein A-I (ApoA-I).METHODS: INS-1E rat cl

The gun test stand from MAX-Lab has been upgraded and moved to a new facility at the MAX IV Laboratory. The new test stand will reuse parts of the equipment from the old test stand but a number of improvements to the setup are be made. In this paper we report on the design of the new gun test stand, research plans in the near future as well as planned and possible future research topics..

The size dependency of fog droplet concentration and composition was studied using newly developed droplet impactors during the CHEMDROP campaign in the Po Valley (Italy). A strong size dependency of solute concentrations was measured during several fog episodes. The ionic strength of the droplet solutions varies as a function of droplet diameter, showing maximum values in the 9-19 μm diameter ran

We report the transverse single-spin asymmetries of J/ψ production at forward and backward rapidity, 1.2

In experimental studies, eosinophils have been shown to promote the survival, proliferation, and retention of plasma cells in the bone marrow (BM). The clinical significance of eosinophils in plasma cell disorders (PCDs) in humans is largely unknown. This study focuses on the frequency and phenotype of eosinophils in the BM and peripheral blood (PB) in patients with untreated PCD compared with hea

Birds, particularly raptors, are believed to forage primarily using visual cues. However, raptor foraging tactics are highly diverse – from chasing mobile prey to scavenging – which may reflect adaptations of their visual systems. To investigate this, we studied the visual field configuration of 15 species of diurnal Accipitriformes that differ in such tactics, first focusing on the binocular fiel

Background: Non-motor symptoms (NMS) are common in late stage Parkinson's disease (PD), as the frequency and severity of most of these symptoms increase with advancing disease. Objective: To assess effect of dopaminergic therapy on NMS in late stage PD and to investigate relationships between dopaminergic effect on NMS and on motor function. Method: Thirty PD patients in Hoehn and Yahr (HY) stages

This paper summarizes the development and application of degenerate four-wave mixing (DFWM), polarization spectroscopy (PS) and laser-induced thermal grating spectroscopy (LITGS) in the mid-infrared spectral region for combustion diagnostics over the last decade.

Introduction: The interaction between different product policies will be crucial for the further advancement of a coherent product policy framework. The Commission has stated that ‘the complex and interlocking approach needed to build a resource-efficient Europe can only be achieved with a policy mix that optimizes synergies and addresses trade-offs between different areas and policies’. In the co

Concerns about the environmental effects of the ‘throwaway society’ are increasingly influencing policy-making and regulatory action in the EU. The Seventh Environment Action Programme, which aims to guide European environmental policy, sets out a long-term vision for the EU that requires a major shift in the way economic activities are conducted: In 2050, we live well, within the planet’s ecologi

Ion-beam thermography (IBT) is used to determine the chemical composition of atmospheric aerosols. The aerosols are analyZed by a combination of four ion-beam techniques PIXE, PESA, pNRA and cPESA during thermography. These techniques monitor the concentrations of the available elements during the stepwise heating of the sample. For each element a thermogram, i.e., the concentration vs. temperatur
