Tuning the spin state of iron phthalocyanine by ligand adsorption

The future use of single-molecule magnets in applications will require the ability to control and manipulate the spin state and magnetization of the magnets by external means. There are different approaches to this control, one being the modification of the magnets by adsorption of small ligand molecules. In this paper we use iron phthalocyanine supported by an Au(111) surface as a model compound

A Unifying Approach to Minimal Problems in Collinear and Planar TDOA Sensor Network Self-Calibration

This work presents a study of sensor network calibration from time-difference-of-arrival (TDOA) measurements for cases when the dimensions spanned by the receivers and the transmitters differ. This could for example be if receivers are restricted to a line or plane or if the transmitting objects are moving linearly in space. Such calibration arises in several applications such as calibration of (a

The emphasis on the equal and eternal responsibility of subjects of different gender and social positions in M.F. Roos's dialogue books promoted a special combination of radical equality in anthropology and a conservative understanding of society. A Pietist teaching on salvation permeates the Orthodox principles on vocation in such a way, that the vocation to community life as a Christian farmer,

Chip Based Electroanalytical Systems for Cell Analysis

This review with 239 references has as its aim to give the reader an introduction to the kinds of methods used for developing microchip based electrode systems as well as to cover the existing literature on electroanalytical systems where microchips play a crucial role for “none-destructive” measurements of processes related to living cells, i.e., systems without lysing the cells. The focus is on

COLDDIAG: A Cold Vacuum Chamber for Diagnostics

One of the still open issues for the development of superconducting insertion devices is the understanding of the heat load induced by the beam passage. With the aim of measuring the beam heat load to a cold bore and in order to gain a deeper understanding in the beam heat load mechanisms, a cold vacuum chamber for diagnostics is under construction. We plan to have access with the same set-up to a

Goniometer Crosstalk Compensation for Knee Joint Applications

Electrogoniometers are prone to crosstalk errors related to endblocks rotation (general crosstalk) and to the characteristics of each sensor (individual crosstalk). The aim of this study was to assess the crosstalk errors due to endblock misalignments and to propose a procedure to compensate for these errors in knee applications. A precision jig was used to simulate pure +/- 100 degrees flexion/ex

Ongoing Work Within ICRP and Other International Organisations in the Field of Radiological Protection in Medicine

This paper is intended to give an overview of the current work of the International Commission on Radiological Protection (ICRP) within the field of medicine and healthcare. The paper focuses on the work carried out in Committee 3. Some views expressed at the ICRP Seminar in Bethesda, USA in October 2011 will also be discussed. Similar and complementary work by other organisatons will also be brie

Genetic screening in sudden cardiac death in the young can save future lives

Autopsy of sudden cardiac death (SCD) in the young shows a structurally and histologically normal heart in about one third of cases. Sudden death in these cases is believed to be attributed in a high percentage to inherited arrhythmogenic diseases. The purpose of this study was to investigate the value of performing post-mortem genetic analysis for autopsy-negative sudden unexplained death (SUD) i

Differences in referral rates to specialised health care from four primary health care models in Klaipeda, Lithuania

Background: Lithuanian primary health care (PHC) is undergoing changes from the systems prevalent under the Soviet Union, which ensured free access to specialised health care. Currently four different PHC models work in parallel, which offers the opportunity to study their respective effect on referral rates. Our aim was to investigate whether there were differences in referrals rates from differe

Erythropoietin suppresses the activation of pro-apoptotic genes in head and neck squamous cell carcinoma xenografts exposed to surgical trauma.

Several studies on the use of erythropoietin (Epo) to treat anaemia in patients undergoing cancer treatment have shown adverse effects on tumour control and survival. Experimental studies indicate that this could be linked to an interaction with wound healing processes and not an effect on tumour cells per se. We have previously shown that erythropoietin in combination with surgical trauma stimula

Improved spectral sensitivity by combining periodic shadowing and high dynamic range imaging

Most emission spectra are characterized by lines of various intensities, a feature making them difficult to probe in their entirety - the limited dynamic range of the detector prohibits the simultaneous observation of both weak and intense spectral features. A further known complication in spectroscopy concerns the generation and detection of stray light, which is an undesired contribution of ligh

Temperature Dependence of the Laminar Burning Velocity of Methanol Flames

To better understand and predict the combustion behavior of methanol in engines, sound knowledge of the effect of the pressure, unburned mixture temperature, and composition on the laminar burning velocity is required. Because many of the existing experimental data for this property are compromised by the effects of flame stretch and instabilities, this study was aimed at obtaining new, accurate d

Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies

Popular Abstract in Swedish De manliga könshormonerna, sk. androgener, spelar en nyckelroll under foster-utvecklingen av de manliga inre (t ex. blåshalskörtel/prostata) och yttre (t ex. penis) könsorganen. Androgenerna stimulerar även tillväxten av desamma under puberteten samt upprätthåller de manliga kroppsegenskaperna under vuxenlivet. De två huvudsakliga androgenerna är testosteron (T) samt 5αAndrogen action plays a pivotal role in male reproductive tract physiology and pathology. The androgen receptor (AR) gene harbors two codon repeat tracts: the CAG and GGN repeats, encoding corresponding amino acid sequences of variable length; the polyglutamine and polyglycine stretches, respectively. Variation in CAG repeat length had been associated with a number of andrological disorders, where

A Novel Method to Simulate the Progression of Collagen Degeneration of Cartilage in the Knee: Data from the Osteoarthritis Initiative.

We present a novel algorithm combined with computational modeling to simulate the development of knee osteoarthritis. The degeneration algorithm was based on excessive and cumulatively accumulated stresses within knee joint cartilage during physiological gait loading. In the algorithm, the collagen network stiffness of cartilage was reduced iteratively if excessive maximum principal stresses were
