Water-related impacts due to change in climatic conditions ranging from water scarcity to intense floods and storms are increasing in developing countries like Pakistan. Water quality and waterborne diseases like hepatitis, cholera, typhoid, malaria and dengue fever are increasing due to chaotic urbanization, industrialization, poor hygienic conditions, and inappropriate water management. The morb

Background: Except for overall survival, whether or not waiting time for treatment could influences other domains of cancer patients' overall well-being is to a large extent unknown. Therefore, we performed this study to determine the effect of waiting time for cancer treatment on the mental health of patients with esophageal or gastric cancer. Methods: Based on the Swedish National Quality Regist

Previous studies of mid-Ordovician limestone in Sweden have shown that over a stratigraphic interval representing a few million years there is a two orders-of-magnitude enrichment in fossil L-chondritic meteorites (empty set = 1-21 cm) and sediment-dispersed extraterrestrial chromite (EC) grains (>63 mu m). This has been interpreted as a dramatic increase in the flux of L-chondritic matter to Eart

Background: Short children born small for gestational age (SGA) are treated with growth hormone (GH) dose based on body size, but treatment may lead to high levels of IGF-I. The objective was to evaluate IGF-I titration of GH dose in contrast to current dosing strategies. Methods: In the North European Small for gestational age study (NESGAS) 92 short pre-pubertal children born SGA were randomised

Precise geochronology, combined with paleomagnetism on mafic intrusions, provides first-order information for paleoreconstruction of crustal blocks, revealing the history of supercontinental formation and break-up. These techniques are used here to further constrain the apparent polar wander path of the Kaapvaal Craton across the Neoarchean-Paleoproterozoic boundary. U-Pb baddeleyite ages of 2441

BACKGROUND: The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item hearing-specific questionnaire. It was developed with the purpose of evaluating the efficacy of hearing aid rehabilitation. Few psychometric properties have been presented for a Swedish translation of the IOI-HA. Furthermore, previous studies have examined the IOI-HA in mainly sensorineural hearing losses, an

Popular Abstract in Swedish Stora framsteg har gjort det möjligt att, med dagens teknik, inte bara visualisera enskilda atomer, utan även utföra olika typer av operationer och manipulationer på atomskalan med stor precision rent experimentellt. Detta har möjliggjort tillverkning av komplexa nanostrukturer genom montering av komponenter av nanostorlek till större sammansatta system, vilket i sin tuNanowires constitute one of the fundamental building blocks in assembled nanodevices. Due to the high surface to volume ratio, the fraction of surface atoms is not negligible for nanosized elements. Because of the reduced coordination of surface atoms, the physical properties deviate from those of the bulk, which influences the overall physical properties of nanostructures. Consequently, this prov

The potential of elemental analysis of light elements by measuring elastically scattered particles as a complement to PIXE (Particle Induced X-ray Emission analysis), when using a 3 MV electrostatic tandem accelerator is discussed. The discussion is based on protons and He ions with energies suitable for PIXE. Some experimental results of scattering yields are included.

Hydrolysis rate constants of sludge at 35°C, 55°C, and 60°C were found to be 0.32 d-1, 0.44 d-1, and 0.50 d-1, respectively in pilot-scale experiments with digestion of municipal sludge in semi-continuously operated reactors. The hydrolysis rate constants as well as estimated chemical oxygen demand (COD) fractions in the feed were implemented in a mathematical model for anaerobic digestion similar

Anaerobic digestion would enable the energy potential of agricultural crop residues such as ley crops, sugar beet tops and straw to be harnessed in Sweden. These residues are so spread out that full utilisation of the potential by centralised slurry-based technology is difficult, its appearing that simple but effective high-solids reactor systems have a better chance of being economically viable o

The aim of this study is to examine the relationship between retailer brand (RB) market shares and consumer prices. Furthermore it investigates whether changes in category price and expenditure are due to changes in customer purchase patterns or changes in relative price levels (price gap) of RBs and national brands (NBs). Data from the market research company GfK's consumer household panel, compr

Human embryonic stem cells (hESCs) are a potential source of dopaminergic neurons for treatment of patients with Parkinson's disease (PD). Dopaminergic neurons can be derived from hESCs and display a characteristic midbrain phenotype. Once transplanted, they can induce partial behavioral recovery in animal models of PD. However, the potential research field faces several challenges that need to be

There is a serious need in the automotive industry to predict surface defects in outer panels. Measures to prevent these defects can not be taken until a test part has been manufactured. This costs a lot in time and money. Within the present project stamping tools for a model part resembling the area around the fuel filler lid was developed. This is an area of the outer surface of a car, which is

In this study, thermal and hydraulic performance of supercritical liquefied natural gas (LNG) is numerically studied in a printed circuit heat exchanger (PCHE) with airfoil fins under a rolling condition. Effects of operating pressures and rolling parameters are investigated. Results indicate that the PCHE has better thermal performance but worse hydraulic performance at a lower pressure condition
