Nitrogen 1s NEXAFS and XPS spectroscopy of NH3-saturated Si(001)-2x1: Theoretical predictions and experimental observations at 300 K

In the light of hybrid functional density-functional theory calculations of the core-excited and core-ionized states, this paper discusses original N 1s x-ray photoemission spectroscopy (XPS) and near-edge x-ray absorption fine-structure (NEXAFS) experimental data on the single-domain (vicinal) Si(001)-2x1 surface saturated by NH3 at 300 K. The theoretical approach enables to discuss the vibration

In Situ Characterization of Nanowire Dimensions and Growth Dynamics by Optical Reflectance

Optical reflectometry is commonly used as an accurate and noninvasive characterization tool when growing planar semiconductor layers. However, thin-film analysis schemes cannot be directly applied to nanowire systems due to their complex optical response. Here, we report on reliable in situ characterization of nanowire growth with high accuracy using optical reflectance spectra for analysis. The m

Diabetes Mellitus Modeling and Short-Term Prediction Based on Blood Glucose Measurements

Insulin-Dependent Diabetes Mellitus (IDDM) is a chronic disease characterized by the inability of the pancreas to produce sufficient amounts of insulin. Daily compensation of the deficiency requires 4-6 insulin injections to be taken daily, the aim of this insulin therapy being to maintain normoglycemia - i.e., a blood glucose level between 4 and 7mmol/l. To determine the quantity and timing of th

An investigation of Cu(II) and Ni(II)-catalysed hydrolysis of (di)imines

The reactions of six diimine ligands with Cu(II) and Ni(II) halide salts have been investigated. The diimine ligands were Ph2C=N(CH2)(n)NC=Ph-2 (n = 2 (Bz(2)en, 1a), 3 (Bz(2)pn, 1b), 4 (Bz2bn, 1c)), N, N'-bis-(2-tert-butylthio- 1-ylmethylenebenzene)-2,2'diamino-biphenyl (2), N,N'-bis-(2-chloro-1-ylmethylenebenzene)-1,3diaminobenzene (3) and N,N'-bis-(2-chloro-1-ylmethylenebenzene)-1,2-ethanediamin

Chyliza leguminicola Melander, 1920 (Diptera: Psilidae) new to the Palaearctic fauna.

The Nearctic species Chyliza leguminicola Melander, 1920 has been found breeding in Denmark. It is reported here for the first time in the Palaearctic region. The first known Danish record is from 1991, and the species is well established at least in the eastern part of Jutland. Data on the distribution as currently known is presented. It is possible that C. leguminicola is actually established bu

Remission maintenance in acute myeloid leukemia: impact of functional histamine H-2 receptors expressed by leukemic cells

Post-consolidation immunotherapy with histamine dihydrochloride and interleukin-2 has been shown to improve leukemia-free survival in acute myeloid leukemia in a phase III trial. For this study, treatment efficacy was determined among 145 trial patients with morphological forms of acute myeloid leukemia as defined by the French-American-British classification. Leukemia-free survival was strongly i

Introduction

Our continuously changing global environment requires continuous and detailed monitoring for us to understand how ecosystems are structured and function in response to climatic changes. Understanding the arctic ecosystems is of particular importance (Oechel et al., 1997). Indeed, rather than in boreal and temperate regions, the forecasted climatic changes will be first and most pronounced in the A

Artificial Redirection of Sensation From Prosthetic Fingers to the Phantom Hand Map on Transradial Amputees: Vibrotactile Versus Mechanotactile Sensory Feedback

This work assesses the ability of transradial amputees to discriminate multi-site tactile stimuli in sensory discrimination tasks. It compares different sensory feedback modalities using an artificial hand prosthesis in: 1) a modality matched paradigm where pressure recorded on the five fingertips of the hand was fed back as pressure stimulation on five target points on the residual limb; and 2) a

Pseudomonas aeruginosa Uses Dihydrolipoamide Dehydrogenase (Lpd) to Bind to the Human Terminal Pathway Regulators Vitronectin and Clusterin to Inhibit Terminal Pathway Complement Attack.

The opportunistic human pathogen Pseudomonas aeruginosa controls host innate immune and complement attack. Here we identify Dihydrolipoamide dehydrogenase (Lpd), a 57 kDa moonlighting protein, as the first P. aeruginosa protein that binds the two human terminal pathway inhibitors vitronectin and clusterin. Both human regulators when bound to the bacterium inhibited effector function of the termina

Treatment of tumour cell with 5-aza-2-deoxycytidine (DAC) for immune tumour therapy of Glioma in Fischer-344 rats

Fisher 344 rats with implanted N29 glioma tumours were treated with Pulsed Electric Fields (PEF) in combination with immunization using either IFN-gamma-gene-transfected syngeneic tumour cells or IFN-gamma transfected N29 cells treated with 10 micro-M 5-aza-2-deoxycytidine (DAC). Tumours (N29) were inoculated subcutaneously on both thighs of female F- 344 syngeneic rats. The left tumour was treate

Production of pi/K/p from intermediate to high p(T) in pp, p-Pb and Pb-Pb collisions measured by ALICE

Hälsopromotion i skolan. Utvärdering av DISA - ett program för att förebygga depressiva symtom hos ungdomar.

Popular Abstract in Swedish Bakgrund Hälsopromotion i skolan förespråkas för att främja välmående och förebygga depressiva symtom hos ungdomar, men insatsernas effektivitet och kostnadseffektivitet behöver utvärderas löpande. Depressiva symtom klassas av WHO som den största sjukdomsbördan hos unga människor och skapar såväl stort lidande för den enskilda och de anhöriga, som höga samhällskostnaderBackground: DISA (Depressive Symptoms In Swedish Adolescents) is a cognitive behavioral intervention aimed at preventing stress and depressive symptoms in adolescents. It is frequently used in Swedish schools for students aged 13-15 years. DISA is commonly offered to females, but at some schools, the intervention is also offered to males. In this study, the application of the intervention for both

Pushed into Unemployment, Pulled into Retirement: Facing Old Age in Gothenburg, 1923-1943

Along with rapid growth and improved standards of living, the first decades of the twentieth century saw the introduction of new technology and new ways to organize production. There are contrasting views on what impact these developments, often summarized as the Second Industrial Revolution, had on the situation of old men in the labour market. Some contemporary observers and modern-day historian

Interval estimation for a binomial proportion: a bootstrap approach

This paper discusses the classic but still current problem of interval estimation of a binomial proportion. Bootstrap methods are presented for constructing such confidence intervals in a routine, automatic way. Three confidence intervals for a binomial proportion are compared and studied by means of a simulation study, namely: the Wald confidence interval, the Agresti-Coull interval and the boots

Planar Motion and Visual Odometry: Pose Estimation from Homographies

This thesis concerns ego-motion and pose estimation of a single camera under the assumptions of planar motion and constant internal camera parameters. Planar motion is common for cameras mounted onto mobile robots, particularly in indoor scenarios, as they remain at a constant height above the ground plane. In Paper A, a parametrisation of the camera motion and pose is presented, along with an ite

Differences in abundance, species richness, and body size of ground beetles (Coleoptera: Carabidae) between beech (Fagus sylvatica L.) forests on Podzol and Cambisol

Ten forest sites with a tree layer of almost pure beech in southern-central Scania, south Sweden, were studied. They were all located in the interior of large forest stands. Five of the stands were developed on mor Podzols with scanty or almost no ground layer vegetation. The other five sites were located on mull Cambisols with a rich ground layer of many vascular plant species and a shrub layer o

Copy Number Variation Analysis in Familial BRCA1/2-Negative Finnish Breast and Ovarian Cancer

Background: Inherited factors predisposing individuals to breast and ovarian cancer are largely unidentified in a majority of families with hereditary breast and ovarian cancer (HBOC). We aimed to identify germline copy number variations (CNVs) contributing to HBOC susceptibility in the Finnish population. Methods: A cohort of 84 HBOC individuals (negative for BRCA1/2-founder mutations and pre-scr
