A large number of diluents were screened to determine the optimum combination between diluent and extractant. Combinations of a C8 tertiary amine and aromatic diluents or of a C12 tertiary amine and aliphatic diluents do not lead to third-phase formation. A flow-sheet for a solvent-extraction process for treatment of various qualities of wet-process phosphoric acid solutions is proposed. Based on
With the increasing focus on reducing emissions and making fuel efficient vehicles within the automotive industry over the past few years, new methods are constantly being investigated to improve the efficiency of the powertrain. One such method is recovering waste heat from the exhaust gases as well as the coolant using a thermodynamic cycle such as a Rankine cycle. However, most studies looking
ESS, a European Research Infrastructure Consortium (ERIC), is getting ready to be a leading multidisciplinary facility with the world's most potent neutron source. Dedicated to scientific breakthroughs, ESS focuses on materials, energy, health, and environmental research to address key societal challenges. ESS will host 22 specialized scientific instruments selected to cover a broad range of exper
The cutting force dynamics in alloyed steel, stainless steel and cast iron have been investigated, although a direct measurement of the cutting forces could not be carried out. Usually, the response of the tool holder shank is measured by strain gauges and will be dependent on the stochastic character of the applied load and the structural dynamic properties of the tool holder. The characterisatio
Three incommensurately modulated gamma-brass-related composite structures in the Ni-Zn system have been solved from Xray single crystal diffraction data using a 3+1 dimensional super space description. The compounds at the end points of the compositional domain NiZn3-delta (-0.09 <= delta <= 0.34) and NiZn3.30 crystallize in the orthorhombic superspace group Fmmm(alpha 00) 0s0 {F = [(1/2, 1/2, 0,
The development since the beginning of the 20th century of the pollen-analytical theory and method as a palaeoecological tool for describing landscape development is outlined with reference to southern Scandinavia. Numerical methods applied since the 1980s are discussed. The aim of this paper is to provide a new perspective on the landscape development and human impact during the Holocene by apply
Ordförandemejl_Återgång till arbetsplatsen20220301[82] Återgång till arbetsplatsen/ Back to workplace Please see below for an English version. Hej! Nu är vi som arbetar på Göteborgs universitet i full gång med en successiv återgång från distansarbete till mer arbete på plats. Under pandemin har anställda på GU gjort viktiga erfarenheter av att arbeta på distans, både negativa och positiva. Som fac
Den 27 oktober 2006 meddelade den engelska appellationsdomstolen (UK Court of Appeal) ett vägledande avgörande i de s.k. Aerotel/Macrossan-avgörandena. Domen relaterade till två mål som berörde tolkningen av det patenterbara området enligt sektion 1 (2) i den engelska patentlagen (Patent Act 1977), vilken motsvarar art. 52 i den Europeiska Patentkonventionen (EPC). Det första målet gällde ett isra
BACKGROUND: Recent studies performed with positron emission tomography have suggested that coronary flow reserve (CFR) is moderately to severely reduced after the arterial switch operation (ASO). These findings are of great concern but have not been confirmed by other methods. METHODS AND RESULTS: Eleven symptom-free children were studied between 4 and 11 (median 6.0) years after the ASO. Flow vel
Due to their wide utilization and low thermodynamic efficiency, there is a large interest in designing more efficient high-pressure homogenizer valves. Drop breakup in these devices is by turbulent interaction downstream of the gap exit. However, recent investigations in scaled systems suggest that the drops can be ‘primed’ for breakup by elongation upstream of the gap entrance. This study uses hy

BACKGROUND: A significant number of patients with primary hyperparathyroidism (pHPT) who are surgically treated have increased serum levels of intact parathyroid hormone (PTH) during long-term follow-up despite normocalcemia. The cause and significance of this finding remain to be established.METHODS: A total of 82 patients operated on for sporadic parathyroid adenoma were investigated before and

Background: To our knowledge there is no report in the literature on measurements of vertebral rotation with low-dose computed tomography (CT) in prone position.Aims: To describe and test the reliability of this new method, compare it with other methods in use and evaluate the influence of body position on the degree of vertebral rotation measured by different radiological methods.Study design: Re
Background: Optimizing rectal suction biopsy (RSB) diagnostics in Hirschsprung’s disease (HD) may shorten diagnostic time and prevent need for repeated biopsies. Aim: To explore whether systematic orientation of fresh RSB specimens increased biopsy quality, diagnostic times, diagnostic efficacy, and histopathologic workload, and to explore these outcome measures for aganglionic specimens.

This work presents a regional climate model, the Rossby Centre regional Atmospheric model (RCA1), recently developed from the High Resolution Limited Area Model (HIRLAM). The changes in the HIRLAM parametrizations, necessary for climate-length integrations, are described. A regional Baltic Sea ocean model and a modeling system for the Nordic inland lake systems have been coupled with RCA1. The cou

Among concentrating solar power technologies, direct steam generation solar tower power plants represent a promising option. These systems eliminate the usage of heat transfer fluids allowing for the power block to be run at greater operating temperatures and therefore further increasing the thermal efficiency of the power cycle. On the other hand, the current state of the art of these systems doe
