Spectral Time Domain IP - Factors Affecting Data Information Content and Applicability to Geological Characterization

A DCIP survey with different timing settings, electrode arrays, cable spreads and waveforms (50\% and 100\% duty cycle waveform) were carried out over the Liikavaara deposit in northern Sweden. All the measured data were inverted using AarhusInv. Measured data with 100\% duty cycle waveform, which is much faster than the conventional 50\% duty cycle waveform, present significant improvements in th

Intensified Arctic warming under greenhouse warming by vegetation–atmosphere–sea ice interaction

Observations and modeling studies indicate that enhanced vegetation activities over highlatitudes under an elevated CO2 concentration accelerate surface warming by reducing thesurface albedo. In this study, we suggest that vegetation-atmosphere-sea ice interactions overhigh latitudes can induce an additional amplification of Arctic warming. Our hypothesis is testedby a series of coupled vegetation

Characteristics of fresh and aged carbonaceous aerosol from anthropogenic combustion sources

Popular Abstract in Swedish Luftburna partiklar från transportsektorn och energiproduktion kan ge upphov till negativa hälsoeffekter hos människor och påverka det globala klimatet. Partiklarnas kemiska och fysikaliska egenskaper förändras när de åldras i atmosfären och ny partikelmassa kan bildas från ämnen som tidigare var i gasfas. Det övergripande syftet med den här avhandlingen är att öka kunsEmissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. The overall aim of this thesis was to investigate how atmospheric transformation and combustion conditions a

Satsmelodi och hjärnaktivitet – Enkelt prat under luppen

Vardagligt tal är i all sin enkelhet en mycket komplicerad process. Lyssnandet likaså. Att över huvudtaget hinna höra och förstå ord som forsar ur någons mun, är ett mindre under. Till synes enkla självklarheter i språket är resultatet av avancerade tolkningar, bedömningar och beslut. Här har mätningar av hjärnaktiviteten under lyssnandet visat sig rymma flera förklaringar till hur pratet når fram

Underlag för energirenovering av klimatskal - en genomgång av tillgänglig låneobjektsstatistik

En stor del av de bostäder som uppfördes före 1990 finansierades med statliga bostadslån och för dessa samlades det in en stor mängd uppgifter avseende byggnadernas tekniska lösningar. Uppgifterna publicerades årligen i Statistiska Meddelande från Statistiska Centralbyrån, SCB. I syfte att upprätta ett underlag för framtagande av typlösningar för energirenovering av dessa klimatskal har underlaget

Fibrolipomatous hamartoma in the median nerve in the arm - an unusual location but with MR imaging characteristics: a case report.

ABSTRACT: Fibrolipomatous hamartoma of the median nerve are usually located distally in the forearm and may have characteristic features on MR imaging. Here we report a patient with an extensive fibrolipomatous hamartoma at an unusual location proximally in the arm, where a preoperative MR imaging was pathognomonic and diagnosis was verified by an incisional biopsy. We suggest that MRI should be p

Chronic pancreatitis: potential future interventions.

Chronic pancreatitis is a common disorder of which the underlying pathogenic mechanisms still are incompletely understood. In the last decade, increasing evidence has shown that activated pancreatic stellate cells play a key role in the fibrosis development associated with chronic pancreatitis as well as pancreatic cancer. During pancreatic injury or inflammation, quiescent stellate cells undergo

Apolipoprotein M affecting lipid metabolism or just catching a ride with lipoproteins in the circulation?

Apolipoprotein M (apoM) is a novel apolipoprotein found mainly in high-density lipoproteins (HDL). Its function is yet to be defined. ApoM (25 kDa) has a typical lipocalin beta-barrel fold and a hydrophobic pocket. Retinoids bind apoM but with low affinity and may not be the natural ligands. ApoM retains its signal peptide, which serves as a hydrophobic anchor to the lipoproteins. This prevents ap

Dose-Dependent Effect of Growth Hormone on Final Height in Children with Short Stature without Growth Hormone deficiency.

Context: Effect of GH therapy in short non GH deficient children, especially idiopathic short stature (ISS) has not been clearly established owing to lack of controlled trials until final height (FH). Objective: To investigate the effect of two GH doses compared with untreated controls on growth to FH in short children mainly with ISS. Design and Setting: A randomized, controlled, long-term multic
