Localization of 2-[125I]lodomelatonin binding sites in the brain of the atlantic salmon, salmo salar L.

The photosensory pineal organ of teleost fish shows a circadian rhythm in melatonin synthesis, and melatonin is known to influence a number of physiological functions. However, the target sites for melatonin are not known. We have investigated the distribution of melatonin binding sites in the brain of the salmon, Salmo salar. Brains were collected for receptor binding assay and autoradiography at

The formation conditions, structure, and properties of the recently discovered phosphide, Si12P5 (initially assigned Si7P3), have been studied using x-ray diffraction, high-resolution transmission electron microscopy, photospectrometry, and a four-point probe. The phosphide formed in amorphous Si-P alloy thin films with 30, 35 and 44 at. % P after annealing at 1000°C for 30 min. During annealing a

The Effect of Precipitation pH on Protein Recovery Yield and Emulsifying Properties in the Extraction of Protein from Cold-Pressed Rapeseed Press Cake

Rapeseed is the second most cultivated oilseed after soybean and is mainly used to produce vegetable oil. The by-product rapeseed press cake is rich in high-quality proteins, thus having the possibility of becoming a new plant protein food source. This study aimed to investigate how the precipitation pH affects the protein yield, protein content, and emulsifying properties when industrially cold-p

Early quality control of stabilised dredged material by correlating heat production with strength

This study explores the use of isothermal calorimetry to assess heat release during the initial phases of dredged sediment stabilization with the primary goal of predicting the 28 days unconfined compressive strength (UCS) and enhancing the stabilization process' quality control (QC). The study was performed on dredged sediment (DS) samples collected from Göta river, Gothenburg, Sweden. The water

Robust abdominal organ segmentation using regional convolutional neural networks

A fully automatic system for abdominal organ segmentation is presented. As a first step, an organ localization is obtained via a robust and efficient feature registration method where the center of the organ is estimated together with a region of interest surrounding the center. Then, a convolutional neural network performing voxelwise classification is applied. The convolutional neural network co

Disease stage dependency of motor and non-motor fluctuations in Parkinson's disease

Recent data suggested a decrease in non-motor fluctuations in late-stage Parkinson's disease (PD), but systematic data on non-motor fluctuations over the whole disease course are mainly lacking. We performed a meta-analysis of two studies with very similar cross-sectional cohort designs, namely the German multicenter Non Motor Fluctuation in PD study and the Swedish part of the European multicente

Oral Ixazomib, lenalidomide, and dexamethasone for multiple myeloma

BACKGROUND Ixazomib is an oral proteasome inhibitor that is currently being studied for the treatment of multiple myeloma. METHODS In this double-blind, placebo-controlled, phase 3 trial, we randomly assigned 722 patients who had relapsed, refractory, or relapsed and refractory multiple myeloma to receive ixazomib plus lenalidomide-dexamethasone (ixazomib group) or placebo plus lenalidomide-dexame

Influence of microbial species on small intestinal myoelectric activity and transit in germ-free rats

The effect of an intestinal microflora consisting of selected microbial species on myoelectric activity of small intestine was studied using germ-free rat models, with recording before and after specific intestinal colonization, in the unanesthetized state. Intestinal transit, neuropeptides in blood (RIA), and neuromessengers in the intestinal wall were determined. Clostridium tabificum vp 04 prom

Evaluation and optimisation of phenomenological multi-step soot model for spray combustion under diesel engine-like operating conditions

In this work, a two-dimensional computational fluid dynamics study is reported of an n-heptane combustion event and the associated soot formation process in a constant volume combustion chamber. The key interest here is to evaluate the sensitivity of the chemical kinetics and submodels of a semi-empirical soot model in predicting the associated events. Numerical computation is performed using an o

Development of Transient Flamelet Library Based Combustion Models

Popular Abstract in Swedish Ämnet för föreliggande avhandling är utveckling av förbränningsmodell för modellering av turbulent icke förblandad förbränning i motorrelaterade tillämpningar. I cylindern i en dieselmotor sker förbränningen under påverkan av och i interaktion med det turbulenta flödesfältet. Det finns härvidlag ett flertal svårigheter för att uppnå acceptabel noggrannhet och acceptablaThree different methods for Reynolds-averaged Navier-Stokes computational fluid dynamics modeling of non-premixed ignition and combustion using tabulated chemistry have been developed. All methods make use of flamelet libraries, where the flamelet auto-ignition process is parameterized using a progress variable. The progress variable parameterization of the auto-ignition chemistry allows for using

The establishment of 20 different human embryonic stem cell lines and subclones; a report on derivation, culture, characterisation and banking

This report summarises our efforts in deriving, characterising and banking of 20 different human embryonic stem cell lines. We have derived a large number of human embryonic stem cell lines between 2001 and 2005. One of these cell lines was established under totally xeno-free culture conditions. In addition, several subclones have been established, including a karyoptypical normal clone from a tri

Comparison of well-mixed and multiple representative interactive flamelet approaches for diesel spray combustion modelling

The application of detailed chemistry to the computational fluid dynamics simulation of combustion process in diesel engines has many potentials, including the possibility to predict auto-ignition, diffusion flame structure, stabilisation and soot formation in a wide range of operating conditions, also taking into account the effects of different fuel types. Among the approaches that were proposed

Continuous-wave laser annealing of Si-rich oxide: A microscopic picture of macroscopic Si-SiO2 phase separation

We report on the first observation of the macroscopic (long-range) phase separation in Si-rich oxide SiOx(x<2) obtained by continuous-wave laser annealing of free-standing SiOx films. The effect is analyzed by a unique combination of microscopic methods (Raman, transmission, photoluminescence, and infrared spectroscopy, transmission electron microscopy, electron energy loss spectroscopy, and x-ray

Psychosocial interventions in drug-free treatment for opiate misuse. Conclusions from RCTs

Background Methadone and buprenorphine are well-documented treatment options for opiate dependence, and there is substantial evidence to support adjunct psychosocial support for methadone maintenance treatment. Although drug-free treatment is preferred by a large number of patients and has considerable political support, less is known about treatment to support and maintain complete abstinence fro

Gold-free growth of GaAs nanowires on silicon: arrays and polytypism

We report growth by molecular beam epitaxy and structural characterization of gallium-nucleated GaAs nanowires on silicon. The influences of growth temperature and V/III ratio are investigated and compared in the case of oxide-covered and oxide-free substrates. We demonstrate a precise positioning process for Ga-nucleated GaAs nanowires using a hole array in a dielectric layer thermally grown on s

Scanning tunneling microscopy study of metal-free phthalocyanine monolayer structures on graphite

Low temperature scanning tunneling microscopy (STM) studies of metal-free phthalocyanine (H2Pc) adsorbed on highly oriented pyrolytic graphite (HOPG) have shown ordered arrangement of molecules for low coverages up to 1 ML. Evaporation of H2Pc onto HOPG and annealing of the sample to 670 K result in a densely packed structure of the molecules. Arrangements of submonolayer, monolayer, and monolayer

Fria varurörelser i den Europeiska gemenskapen. En studie av gränsdragningen mellan gemenskapsangelägeheer och nationella angelägenheter.

This thesis concerns the Articles 30, 34 and 36 of the EC-Treaty and conflicts of competence between the Community and the Member States. It deals especially with the delimitation between community concerns and national concerns in the field of non-tariff barriers to trade in community law. A new perspective concerning the application of Articles 30 and 34 of the EC-Treaty is introduced. It is arg
