Reduction of the barrier height and enhancement of tunneling current of titanium contacts using embedded Au nano-particles on 4H and 6H silicon carbide

We have investigated the electrical characteristics of Ti Schottky contacts with embedded Au nano-particles on various types of epilayers of SiC (4H- and 6H-SiC). From our current-voltage (I-V) and capacitance-voltage (C-V) measurements, we observed that Ti Schottky contacts with embedded Au nano-particles had 0.19 eV (n-4H-SiC) and 0.15 eV (n-6H-SiC) lower barrier height than those of particle fr

2006. Nilsson Stutz, L. Setting it Straight. A re-analysis of the Mesolithic Barum burial according to the principles of Anthropologie ‘de terrain.’

The Mesolithic burial from Barum in Northeastern Scania has long been a subject of academic controversy regarding both the age of the burial and the sex assessment of the remains. A less public discussion has taken place regarding the initial position of the body in the burial. In this article, the documentation of the burial is analyzed in detail according to the taphonomic principles of anthropo

Hadronic matrix elements for kaons

We review some work done by us calculating matrix elements for Kaons. Emphasis is put on the matrix elements which are relevant to predict non-leptonic Kaon CP violating observables. In particular, we recall our results for the (B) over cap (K) parameter which governs the (K-0) over bar - K-0 mixing and update our results for epsilon(K)' including estimated all-higher-order CHPT corrections and th

Notes on the cetrarioid lichens.

The new species Cetraria peruviana is described and its systematic position is discussed. Cetraria nivalrs is reported as new from New Guinea, and its ascomata are described.

Importance of ERK1/2 in upregulation of endothelin type B receptors in cerebral arteries

1 This study examines the importance of mitogen-activated protein kinases (MAPKs) in upregulation of endothelin type B (ETB) receptors. 2 Rat middle cerebral arteries (MCAs) were incubated for 24 h with or without kinase inhibitors. Vessel segments were mounted in myographs and the contractile responses to endothelin-1 (ET-1; ETA and ETB receptor agonist) and sarafotoxin 6c (S6c; ETB receptor agon

CMOS Transceiver Front-Ends in Mobile Communication Handsets - Architectures and Building Blocks

For mobile communication systems in the low-GHz range, CMOS has increasingly become the technology of choice, and the level of integration in mobile handsets has risen. The use of off-chip components, which increases the handset assembly time and costs, is preferably avoided. However, integrating a complete transceiver on a single chip leads to disturbances between building blocks. This imposes ne

Proton and Electron Microprobe Analysis of Human Skin

In order to demonstrate the feasibility of the proton microprobe in the analysis of dermatological material when a spatial resolution of a few micrometres is sufficient and to compare it with the electron microprobe technique, duplicate sections of human skin have been analysed with both methods. A skin sample was obtained from each of three healthy volunteers. After cryosectioning (12 μm) and fre

Quality control of MHC class I maturation

Assembly of MHC class I molecules in the ER is regulated by the so-called loading complex (LC). This multiprotein complex is of definite importance for class I maturation, but its exact organization and order of assembly are not known. Evidence implies that the quality of peptides loaded onto class I molecules is controlled at multiple stages during MHC class I assembly. We recently found that tap

Effects of whey proteins on glycaemia and insulinaemia to an oral glucose load in healthy adults; a dose-response study.

Background/Objectives:Whey proteins have insulinogenic properties and the effect appears to be mediated from a postprandial plasma amino-acid (AA) response. The aim was to study the possible dose-response relationship between whey intake and glycaemic-, insulinaemic- and plasma AA responses.Subjects/Methods:Twelve healthy volunteers participated in the study. They were provided three whey protein

The effect of asset visibility on managing returnable transport items

Purpose – The purpose of this paper is to propose a framework of the potential benefits of asset visibility in the context of returnable transport items (RTI), and uses the framework to examine the effect of asset visibility on the management of RTI systems. Design/methodology/approach – A combined case study and simulation approach was used. A case study was performed to identify and understand

Search for strong production of supersymmetric particles in final states with missing transverse momentum and at least three b-jets at root s=8 TeV proton-proton collisions with the ATLAS detector

This paper reports the results of a search for strong production of supersymmetric particles in 20.1 fb(-1) of proton-proton collisions at a centre-of-mass energy of 8 TeV using the ATLAS detector at the LHC. The search is performed separately in events with either zero or at least one high-p (T) lepton (electron or muon), large missing transverse momentum, high jet multiplicity and at least three

Leisure activities in rheumatoid arthritis: Change after disease onset and associated factors

The objective of this investigation was to examine the relationship between leisure-time occupations, quality of life disease activity among patientswith rheumatoid arthritis. Fifty patients with rheumatoid arthritis-39 females and 11 males, age 30-45 years and belonging to functional class I-III according to Steinbrocker er al (1949)-were recuited from the register at a hospital clinic and from a

Exercise-induced rib stress fractures: influence of reduced bone mineral density

Exercise-induced rib stress fractures have been reported frequently in elite rowers during the past decade. The etiology of rib stress fractures is unclear, but low bone mineral density (BMD) has been suggested to be a potential risk factor for stress fractures in weight-bearing bones. The present study investigated BMD in seven Danish national team rowers with previous rib stress fracture (RSF) a
