Two new rotational bands of distinct character have been identified in Hf-164. They are suggested to correspond to the long-anticipated triaxial strongly deformed (TSD) bands predicted by theoretical studies. The bands have been linked to known states, and the level spins and energies could be determined. The bands are also substantially stronger in intensity and are located at lower spins than th

The far-infrared spectra of solid orthodeuterium and solid normal deuterium are presented and compared to the corresponding spectra of solid parahydrogen and solid normal hydrogen. Spectra of water in orthodeuterium are compared to spectra of water in parahydrogen. The water rotation constants in orthodeuterium are approximately 80% of the rotation constants of water in parahydrogen. The S(0)(0) b

A small number of proteins have the unusual property of tasting intensely sweet. Despite many studies aimed at identifying their sweet taste determinants, the molecular basis of protein sweetness is not fully understood. Recent mutational studies of monellin have implicated positively charged residues in sweetness. In the present work, the effect of overall net charge was investigated using the co

Snow, water, ice, and permafrost are showing evidence of substantial change in the Arctic, with large variations among different geographical areas. As a result of these changes, some habitats and their associated ecosystems are expanding, while others are undergoing rapid contraction. The warming of the Arctic cryosphere is limiting the range for cold-adapted biota, and less specialized taxa incl

The gamma-ray decay of isomeric states in the even-even nucleus Cd-128 has been observed. The nucleus of interest was produced both by the fragmentation of Xe-136 and the fission of U-238 primary beams. The level scheme was unambiguously constructed based on.. coincidence relations in conjunction with detailed lifetime analysis employed for the first time on this nucleus. Large-scale shell-model c

This study addresses the timing and pressure-temperature (P-T) conditions of ophiolite obduction, one of the proposed causes of the ca. 470 Ma Grampian orogeny of Scotland and Ireland. This event gave rise to the main structural and metamorphic characteristics of the Grampian terrane-the type area for Barrovian metamorphism, the cause of which remains enigmatic despite a century of research.

Popular Abstract in Swedish För att ett transplanterat organ ska accepteras av mottagaren behövs immunhämmande läkemedel. Dessa läkemedel dämpar immunförsvaret och förhindrar avstötning av det transplanterade organet. Immunförsvaret har olika sätt att angripa organet, som det uppfattar som kropps-främmande. Idag används olika läkemedel i kombination som behandling mot avstötning. Tyvärr är dessa mTransplantation of vital organs is today a widely used treatment when failure of the organ is a fact. To prevent rejection immunosuppresive treatment must be maintained lifelong, unless transplantation is perfomed between identical twins. Many immunosuppresive agents introduced in clinical practice have been benificial in improving graft survival rates, but adverse effects remains a huge problem t

It was predicted by Wigner in 1934 that an electron gas will undergo a transition to a crystallized state when its density is very low. Whereas significant progress has been made toward the detection of electronic Wigner states, their clear and direct experimental verification still remains a challenge. Here we address signatures of Wigner molecule formation in the transport properties of InSb nan

The concept of society and its cognates have long been widely invoked in order to understand International Relations. Theories of international society distinguish between a society of states and a mere system of states, and theories of world society assume that the world constitutes a single social space. In order to come to terms with the social character of International Relations, constructivi

Popular Abstract in Swedish Diabetes är en snabbt växande folksjukdom som redan har drabbat 200 miljoner världen runt. Det finns två typer av sjukdomen: typ I samt typ II diabetes. Den förstnämnda drabbar vanligtvis de unga och beror på en s.k. autoimmun reaktion där kroppens egna immunförsvar av okänd anledning plötsligt inte känner igen insulincellerna och börjar attackera dem. Typ II diabetes uDiabetes affects around 200 million people worldwide. Curing diabetes would require the prevention of autoimmune destruction of beta cells and restoration of the beta cell mass restored either through regeneration or transplantation of the insulin producing cells. Islet transplantation according to the Edmonton protocol have been the most promising therapeutic option for Diabetes type I patients,

Sepsis is one of leading cause of death despite aggressive surgical intervention and antibiotic therapies. Excessive neutrophil recruitment is a major feature in early phase with immune system dysfunction at later phase. Lung is the most vulnerable, critical and sensitive organ during sepsis process. The aim of thesis was to prevent excessive neutrophil accumulation in lung parenchyma on one hand,

Background: ADAMTS13 is the physiological von Willebrand factor (VWF)-cleaving protease. The aim of this study was to examine ADAMTS13 expression in kidneys from ADAMTS13 wild-type (Adamts13(+/+)) and deficient (Adamts13(-/-)) mice and to investigate the expression pattern and bioactivity in human glomerular endothelial cells. Methodology/Principal Findings: Immunohistochemistry was performed on k

Aims: The aim of this study was to estimate the self-reported domestic incidence of acute gastrointestinal illness in the Swedish population irrespective of route of transmission or type of pathogen causing the disease. Previous studies in Sweden have primarily focused on incidence of acute gastrointestinal illness related to consumption of contaminated food and drinking water. Methods: In May 200

BACKGROUND: The liver plays a key role in the metabolism of plasma apolipoproteins, endogenous lipids and lipoproteins. Hepatocellular carcinoma is one of the most common fatal malignant tumors in China and in other Southeast Asian countries. It has been demonstrated that plasma lipid profiles are changed in liver cancer. DATA SOURCES: A MEDLINE database search was performed to identify relevant a

The non-motor symptoms (NMS) of Parkinson's disease (PD) are often poorly recognized and inadequately treated in contrast to motor symptoms and a modern holistic approach to treatment of PD should, therefore, include recognition and assessment of NMS. Certain aspects of the NMS complex of PD can be improved with currently available treatments, both dopaminergic and non-dopaminergic, but other feat

This article introduces a continuous, gas-phase method for depositing thin metallic coatings onto (nano)particles using a type of physical vapor deposition (PVD) at ambient pressure and temperature. An aerosol of core particles is mixed with a metal vapor cloud formed by spark ablation by passing the aerosol through the spark zone using a hollow electrode configuration. The mixing process rapidly

The observed almost complete dominance of prolate over oblate deformations in the ground states of deformed even-even nuclei is related to the splitting of high center dot "surface" orbits in the Nilsson diagram: on the oblate side the occurrence of numerous strongly avoided crossings which reduce the fanning out of the low Lambda orbits, while on the prolate side the same interactions increase th

The present study proposes a novel sorting algorithm for identification of patients with atrial fibrillation in large one-lead ECG repositories. Repeated measurements at home with automatic transmission of data to a central database is presently tested in the search for atrial fibrillation for the long-term purpose to reduce the incidence of stroke. Such screening rapidly generates large databases
