Doping of semiconductor nanowires

A cornerstone in the successful application of semiconductor nanowire devices is controlled impurity doping. In this review article, we discuss the key results in the field of semiconductor nanowire doping. Considerable development has recently taken place in this field, and half of the references in this review are less than 3 years old. We present a simple model for dopant incorporation during i

Flight speeds of swifts (Apus apus): seasonal differences smaller than expected.

We have studied the nocturnal flight behaviour of the common swift (Apus apus L.), by the use of a tracking radar. Birds were tracked from Lund University in southern Sweden during spring migration, summer roosting flights and autumn migration. Flight speeds were compared with predictions from flight mechanical and optimal migration theories. During spring, flight speeds were predicted to be highe

On Leukocyte Recruitment in Cholestatic Liver Injury

Cholestasis is a frequent clinical syndrome, which is caused by a dysfunction in bile formation of the hepatocyte or from obstruction of the biliary tract. This is associated with inflammation of the liver tissue, resulting in severe liver injury. In this inflammatory process, leukocyte recruitment has emerged as a key feature. Therefore, the aim of this thesis was to analyze the detailed mechanis

'Needle and Stick' save the world: Sustainable development and the universal child

This text deals with a problem concerning processes of the productive power of knowledge. We draw on so called poststructural theories challenging the classical image of thought – as hinged upon a representational logic identifying entities in a rigid sense – when formulating a problem concerning the gap between knowledge and the object of knowledge. More specifically we are looking at this proble

Geo-mapping of time trends in childhood caries risk - a method for assessment of preventive care

Background: Dental caries is unevenly distributed within populations with a higher burden in low socio-economy groups. Several attempts have been made to allocate resources to those that need them the most; there is a need for convenient approaches to population-based monitoring of caries risk over time. The aim of this study was to develop the geo-map concept, addressing time trends in caries ris

Spectral characterization of diffusion with chemical shift resolution: Highly concentrated water-in-oil emulsion.

We present a modulated gradient spin-echo method, which uses a train of sinusoidally shaped gradient pulses separated by 180 degrees radio-frequency (RF) pulses. The RF pulses efficiently refocus chemical shifts and de-phasing due to susceptibility differences, resulting in undistorted, high-resolution diffusion weighted spectra. This allows for the simultaneous spectral characterization of the di

Histology of adipose tissue inflammation in Dercum's disease, obesity and normal weight controls: a case control study.

BACKGROUND: Dercum's disease (DD) is characterised by obesity and chronic pain (> 3 months) in the adipose tissue. The pathogenesis of DD is unknown, but inflammatory components have been proposed. In previous reports and studies, an inconsistent picture of the histological appearance of the adipose tissue in DD has been described. The aim of this investigation was to examine the histological app

Lithium and brain plasticity - studies on glial cell changes and electroconvulsive treatment-induced amnesia in rats

Depression and bipolar disorder, collectively known as mood disorders, are devastating, common and often chronic illnesses. Imaging studies of patients with mood disorders have demonstrated structural changes in several brain regions implicated in mood regulation. Furthermore, bipolar disorder is associated with white matter abnormalities and post mortem analysis of brain tissue from patients with

Self-rated mental health, school adjustment, and substance use in hard-of-hearing adolescents

This survey, "Life and Health-Young People 2005," included all 15/16-year-old adolescents in mainstream schools in the county of Orebro, Sweden. just students with a slight/mild or moderate hearing loss were included. There were 56 (1.9%) "hard-of-hearing (HH) students with multiple disabilities," 93 (3.1%) students who were "just HH," 282 (9.7%) students with some "other disability than HH," and

Structure and function of the ectomycorrhizal association between Paxillus involutus (Batsch) Fr. and Betula pendula Roth .L. Dynamics of mycorrhiza formation

Detailed examination of the structural and functional integration taking place during mycorrhiza formation necessitates rapid and aseptic synthesis of uniform mycorrhizal structures at well-defined stages of development. A system is described for formation of ectomycorrhizas between Betula pendula Roth. and Paxillus involutus (Batsch) Fr. Small sterile seedlings were placed directly on fungal colo

Nontypeable Haemophilus influenzae Protein E Binds Vitronectin and Is Important for Serum Resistance

Nontypeable Haemophilus influenzae (NTHi) commonly causes local disease in the upper and lower respiratory tract and has recently been shown to interfere with both the classical and alternative pathways of complement activation. The terminal pathway of the complement system is regulated by vitronectin that is a component of both plasma and the extracellular matrix. In this study, we identify prote

Perforated cylinders for heat demanding craft

Perforated vessels in one form or the other are found in ceramic assemblages in most societies from early prehistoric time onwards. They vary greatly in shape and size, indicating a multitude of uses. This paper focuses on a particular type of perforated vessel – the perforated open cylinder, a “vessel” with no base, or rather with rims at both ends. This means that its function as a container is
