Bose-Einstein condensation of excitons in Cu2O

We present a parameter-free model that estimates the density of excitons in Cu2O, related to experiments that have tried to create an excitonic Bose-Einstein condensate. Our study demonstrates that the triplet-state excitons move along adiabats and obey classical statistics, while the singlet-state excitons are a possible candidate for forming a Bose-Einstein condensate. Finally we show that the r

Different patterns in immunoreactive anionic and cationic trypsinogen in urine and serum in human acute pancreatitis

BACKGROUND: Acute pancreatitis (AP) results in elevated concentrations of trypsinogen (T) isoenzymes in serum. Immunoreactive anionic trypsinogen in urin (irAT/u) is elevated in AP, and has recently been proposed as a rapid diagnostic instrument and severity predictor. These results have not been confirmed by other groups, and irAT/u has not been further characterized. The concentration of immun

Cycle-to-Cycle Control of a Dual-Fuel HCCI Engine

A known problem of the HCCI engine is its lack of direct control andits requirements of feedback control. Today there exists severaldifferent means to control an HCCI engine, such as dual fuels,variable valve actuation, inlet temperature and compression ratio.Independent of actuation method a sensor is needed. In this paper weperform closed-loop control based on two different sensors, pressureand

A systematic overview of radiation therapy effects in non-small cell lung cancer

A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for non-small cell lung cancer (NSCLC) is based on data from 4 meta-analys

Evidence of ultra-fast dissociation in ammonia observed by resonant Auger electron spectroscopy

We present evidence for ultra-fast dissociation of molecular ammonia when photo-excited to the Nls --> 4a(1) core-hole state. This finding is based on resonant Auger spectroscopical results as well as qualitative arguments concerning the photon energy dependence of the Auger structures. Calculations of the excited state potential based on the Z + l approximation were performed. Both the calculatio

L-lactate after embolization of the superior mesenteric artery

Background. Plasma markers for intestinal ischemia have not proven to be accurate. The value of L-lactate is unclear. Experimental models based on open surgery confound the effects of surgical trauma with that of ischemia. The aim was to create an endovascular model for acute superior mesenteric artery thromboembolism, and then to study L-lactate and lactate dehydrogenase (LD) activity in plasma a

Putting evolutionary biology back in the ecological theatre: a demographic framework mapping genes to communities

Question: How can we link genotypic, phenotypic, individual, population, and community levels of organization so as to illuminate general ecological and evolutionary processes and provide a framework for a quantitative, integrative evolutionary biology? Framework: We introduce an evolutionary framework that maps different levels of biological diversity onto one another. We provide (1) an overview

First evidence for excited states in In-101

The first evidence for excited states in In-101 is presented. In-101 is the lightest In isotope observed in an in-beam experiment. Two gamma-ray transitions at 1309 and 341 keV, respectively, are strong candidates for a cascade to the ground state in this nucleus. In shell-model terms it has one proton hole and two neutron particles outside the double shell closure at Sn-100. New ideas for improvi

Open Wounds? Trianon, the Holocaust and the Hungarian Trauma

The Trianon treaty has been a prominent site of memory in Hungarian historical culture from the day it was undersigned on 4 June 1920. 564,000 Hungarian Jews became victims of the Holocaust. In the first years after the end of World War II, the Holocaust was not a concept in Hungarian politics and historical culture. In the interwar period, in Hungarian historical culture the Trianon syndrome exhi

Low adherence with antihypertensives in actual practice: the association with social participation - a multilevel analysis

Background: Low adherence is a key factor in explaining impaired effectiveness and efficiency in the pharmacological treatment of hypertension. However, little is known about which factors determine low adherence in actual practice. The purpose of this study is to examine whether low social participation is associated with low adherence with antihypertensive medication, and if this association is

Biotransport of organic pollutants to an inland Alaska Lake by migrating Sockeye Salmon (Oncorhynchus nerka)

Persistent organic pollutants such as polychlorinated biphenyls (PCBs) and the pesticide DDT, known to harm wildlife, have been shown to reach pristine Subarctic and Arctic areas by global atmospheric transport. Another transport route for pollutant entry into these ecosystems is provided by migrating salmon. Pollutant transport was studied in a population of sockeye salmon (Oncorhynchus nerka) in

Effects of systematic clinical supervision on psychiatric nurses' sense of coherence, creativity, work-related strain, job satisfaction and view of the effects from clinical supervision: a pre-post test design

There are few investigations of the type and the outcome of interventions aimed at supporting nurses caring for psychiatric patients. Therefore a prepost-test design study was used in which 22 psychiatric nurses, on a general psychiatric ward were examined before, during and after one year of systematic clinical supervision combined with supervised documented, planned, individualized care. The met

Combustion Chambers for Natural Gas SI Engines Part 2: Combustion and Emissions

The objective of this paper is to investigate how the combustion chamber design will influence combustion parameters and emissions in a natural gas SI engine. Ten different geometries were tried on a converted Volvo TD102 engine. For the different combustion chambers emissions and the pressure in the cylinder have been measured. The pressure in the cylinder was then used in a one-zone heat-releas

Superporous agarose beads as a hydrophobic interaction chromatography support

Superporous agarose beads were used as a support for hydrophobic interaction chromatography. These beads have large connecting flow pores in addition to their normal diffusion pores. The flow pores, which are approximately one fifth of the overall diameter of the superporous agarose beads, were earlier shown to give the beads improved mass transfer properties relative to homogeneous agarose beads
