Synthesis and application of PEGylated tracer particles for measuring protein solution viscosities using Dynamic Light Scattering-based microrheology

The measurement of flow properties, such as the zero shear viscosity, of protein solutions is of paramount importance for many applications such as pharmaceutical formulations, where the syringeability of physiologically effective doses is a key property. However, the determination of these properties with classical rheological methods is often challenging due to e.g. detrimental surface effects o

Pure rotational coherent anti-Stokes Raman spectroscopy of ethylene, experiments and modelling

Rotational coherent anti-Stokes Raman spectroscopy (CARS) is an established diagnostic technique for temperature and concentration measurements in combustion-related experiments. CARS has mainly been applied on di- and tri-atomics with linear molecular symmetry, for which good agreement is achieved between experimental and theoretical spectra. Hydrocarbons have so far been less attractive for rota

Developmental tuning in a spinal nociceptive system: effects of neonatal spinalization

Recent studies indicate a modular organization of the nociceptive withdrawal reflex system. Each module has a characteristic receptive field, closely matching the withdrawal movement caused by its effector muscle. In the rat, the strength of the sensory input to each module is tuned during the first postnatal weeks, i.e., erroneous spinal connections are depressed, and adequate connections are str

Differential inhibitory effect on human nociceptive skin senses induced by local stimulation of thin cutaneous fibers

It is known that stimulation of thin cutaneous nerve fibers can induce long lasting analgesia through both supraspinal and segmental mechanisms, the latter often exhibiting restricted receptive fields. On this basis, we recently developed a new method, termed cutaneous field stimulation (CFS), for localized stimulation of A delta and C fibers in the superficial part of the skin. In the present stu

An evaluation of analyses and data collection of winter loss in honey bees in Sweden

Syftet med detta uppdrag har varit att utvärdera hur data på vinterförluster hos honungsbin i Sverige samlas in och analyseras, samt ge förslag på förbättringarav övervakning och analys.Denna rapport innehåller• En sammanställning av faktorer som kan påverka vinterförluster hos honungsbin under svenska förhållanden• En beskrivning av nuvarande sätt att rapportera och analysera vinterförluster i SvThis report evaluates current collection and use of data on winter loss in honey bees in Sweden and is a commission from the Swedish Professional BeekepersAssociation. It includes an overview of factors which may influence winter loss in honey bees in Sweden. In Sweden, data on winter loss is collected by twoinstances, the COLOSS survey and the Swedish Beekeepers Association (SBR). We identify sev
