Climatic control of the surge periodicity of an Icelandic outlet glacier
Surging outlet glaciers are important in draining large ice caps, but the mechanisms controlling surge periodicities are poorly known. We investigated a sediment sequence from the glacier-fed Lake Logurinn in eastern Iceland, and our unique annually resolved data, based on sedimentary varves, imply that Eyjabakkajokull, an outlet glacier of Vatnajokull, began surging about 2200 cal a BP (before 19
Low-frequency noise in vertical InAs nanowire FETs
This letter presents dc characteristics and low-frequency noise (LFN) measurements on single vertical InAs nanowire MOSFETs with 35-nm gate length and HfO2 high-kappa dielectric. The average normalized transconductance for three devices is 0.16 S/mm, with a subthreshold slope of 130 mV/decade. At 10 Hz, the normalized noise power S-I/I-d(2) measures 7.3 x 10(-7) Hz(-1). Moreover, the material-depe
Quarry marks in Partition B, Main Quarry at Gebel el Silsila : remarks on their meaning and function
Famous for its many New Kingdom stelai and funerary shrines, Speos of Horemheb and magnificent quarries, this paper presents a preliminary report on a lesser acknowledged feature of Gebel el Silsila: its quarry marks. Focusing here on the northern section – Partition B – of Silsila East’s Main Quarry, seventeen individual quarry faces display totally 376 quarry marks, which have been divided into
Three different antibodies for estrogen receptor analysis in breast cancer - implications for positive frequency, reproducibility and clinical outcome
Complications and survival after surgical treatment of 214 metastatic lesions of the humerus
Background: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus. Materials and methods: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus. Reconstructions were achieved by intram
Superoxide dismutase inspired Fe(III)-amino acid complexes covalently grafted onto chloropropylated silica gel - Syntheses, structural characterisation and catalytic activity
In this work the syntheses, structure and SOD activity of covalently grafted Fe(III)-complexes formed with various N- or C-protected amino acid ligands (L-histidine and L-tyrosine) inspired by the active site of the Fe SOD enzyme are presented. Chloropropylated silica gel was used as support to mimic the proteomic skeleton of the enzyme. Anchored complexes having uniform amino acids as well as the
Författarens funktioner. Gestaltningen av det litterära arbetet i Motståndets estetik av Peter Weiss
Analysis of the novel Die Ästhetik des Widerstands (The Aesthetics of Resistance) by German-Swedish author Peter Weiss (1916-1982). The main question in the analysis is how the novel depicts the the literary work, since the narrator of the novel is a writer.
GENERAL ORAL GLUCOSE TOLERANCE TEST DURING PREGNANCY, AN OPPORTUNITY FOR IMPROVED PREGNANCY OUTCOME AND IMPROVED FUTURE HEALTH.
Popular Abstract in Swedish Graviditetsdiabetes (GDM) definieras som förhöjt blodglukos (blodsocker) som uppstår eller upptäcks under graviditet och som oftast försvinner efter förlossningen. Orsaken anses vara en otillräcklig förmåga att öka insulinproduktionen i takt med det ökade behov som normalt uppträder under en graviditet till följd av hormonella förändringar. Livsstilsfaktorer såsom stillGestational diabetes mellitus (GDM) is associated with a risk of adverse pregnancy outcome and is a predictor of subsequent diabetes. The aims of this work were to describe a reliable routine to diagnose abnormal glucose tolerance during pregnancy, to investigate women’s opinions of the specialist care provided, to determine the prevalence of diabetes one year after giving birth, and to elucidate
Risk factors and prevention among patients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital
Aims and objectives. This study aimed to describe and identify risk factors associated with hospital-acquired pressure ulcers among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. Background. Pressure ulcers occur most often in older and imm
Low-Dose Prostacyclin Attenuates A Decrease In Plasma Volume Following Nonhemorrhagic Trauma In Rats
Unperturbed moderator brightness in pulsed neutron sources
The unperturbed neutron brightness of a moderator can be defined from the number of neutrons leaving the surface of a moderator completely surrounded by a reflector. Without openings for beam extraction, it is the maximum brightness that can be theoretically achieved in a moderator. The unperturbed brightness of a cylindrical cold moderator filled with pure para-H-2 was calculated using MCNPX; the
Securitization of energy supply chains in China
Energy policies in China, the world’s largest energy consumer, are an important factor in shaping the 41 global energy system. While scholars agree that energy security is a major driver of China’s energy 42 policies, there is insufficient understanding of what exactly constitutes China’s energy security from the 43 policy perspective. We apply recent insights from the Global Energy Assessment, pa
PREDICTIVE AND PROGNOSTIC MARKERS IN SQUAMOUS CELL CARCINOMA OF THE HEAD AND NECK
Survival of patients with locally advanced head and neck squamous cell cancer(HNSCC)is poor, with an overall survival < 50%, despite diagnostic and therapeutic advances. The identification of prognostic and predictive markers could help optimizing treatment. From 18 patients, six tumour cell lines were established and four were xenografted to nude mice. Proliferation parameters(cell doubling time,
Search for supersymmetric particles in events with lepton pairs and large missing transverse momentum in root s=7 TeV proton-proton collisions with the ATLAS experiment
Results are presented of searches for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in root s = 7 TeV proton-proton collisions at the Large Hadron Collider. Search strategies requiring lepton pairs with identical-sign or opposite-sign electric charges are described. In a data sample corresponding to an integr
Mechanism Insights of Ethane C-H Bond Activations by Bare [Fe-III=O](+): Explicit Electronic Structure Analysis
Alkane C-H bond activation by various catalysts and enzymes has attracted considerable attention recently, but many issues are still unanswered. The conversion of ethane to ethanol and ethene by bare [Fe-III=O](+) has been explored using density functional theory and coupled-cluster method comprehensively. Two possible reaction mechanisms are available for the entire reaction, the direct H-abstrac
Striving for scientific stringency: a re-analysis of a randomised controlled trial considering first-time mothers' obstetric outcomes in relation to birth position
Background: The aim of this study was to compare maternal labour and birth outcomes between women who gave birth on a birth seat or in any other position for vaginal birth and further, to study the relationship between synthetic oxytocin augmentation and maternal blood loss, in a stratified sample. Methods: A re-analysis of a randomized controlled trial in Sweden. An on-treatment analysis was used
Cell coupling and exocytosis measured in intact mouse pancreatic islets Control of {delta}-cell secretion
Patch-clamp and capacitance measurements were applied to α-, β- and δ-cells in intact mouse pancreatic islets. The maximum rate of β-cell exocytosis during a depolarization to 0 mV was 14 granules/s,
Gating attosecond pulses in a noncollinear geometry
The efficient generation of isolated attosecond pulses (IAPs), giving access to ultrafast electron dynamics in various systems, is a key challenge in attosecond science. IAPs can be produced by confining the extreme ultraviolet emission generated by an intense laser pulse to a single field half-cycle or, as shown recently, by employing angular streaking methods. Here, we experimentally demonstrate
