Clusters, nanoparticles, nanowires, long molecules as nanotubes and polynucleotides, and functional supramolecular nanostructures are currently considered as potential building blocks for nanotechnology and nanoelectronic devices and circuits, and development and introduction of new methods to control effectively their structure, composition and nanoscale organization are necessary. Here we descri
RFID (radio frequency identification) technology is developing at a rapid pace. During the last few years, it has been widely discussed in logistics research, as well as in other scientific fields which also approach and contribute to the development of RFID technology. In both logistics and related fields there are findings regarding RFID technology which influence logistics. However, an overall
The development of chronic bronchitis (CB) and chronic obstructive airway disease (COAD) seems to be related to inflammatory changes of airway structure. However, the cause and the exact location and type of these changes resulting in altered airway function are not known. Mucosal inflammation is characterized by the recruitment of granulocytes, macrophages and lymphocytes as well as by the sheddi
A peripheral nerve injury has a profound impact on the patient’s life and such an injury causes high costs for society. A peripheral nerve injury is a very complex injury because it involves both peripheral and central components of the nervous system all the way from targets at muscle and skin receptors up to the brain. In the neuron and its supporting cells—mainly Schwann cells—there are numerou
Buda-Lund hydro-model fits are compared to BRAHMS, PHENIX, PHOBOS and STAR data on identified particle spectra, two-particle Bose-Einstein or HBT correlations, charged particle pseudorapidity distributions and pseudorapidity as well as PT dependent elliptic flow in rootS(NN) = 130 and 200 GeV Au+Au collisions at RHIC. Preliminary results indicate that 7/8 of the particle emitting volume is rather
Children’s target experiences (as recipients of prosocial peer acts and victims of peer aggression) were investigated for their concurrent and longitudinal associations with prosocial and aggressive behavior. Forty-four children (initially 22–40 months) were observed in naturalistic interactions with peers during a two-month period for each of three consecutive years. Results revealed no consisten
Cancer of unknown primary site (CUP) may be called an orphan disease, as it is diagnosed when metastases are detected while the primary tumor typically remains undetected, and because little research has been done on its primary causes. So far, few epidemiological studies, if any, have addressed possible risk factors for CUP. We analyzed data from the European Prospective Investigation into Cancer
Background. Evidence-based guidelines are needed to guide effective long-term follow-up (LTFU) of childhood cancer survivors (CCS) at risk of late adverse effects (LAEs). We aimed to ascertain the use of LTFU guidelines throughout Europe, and seek views on the need for pan-European LTFU guidelines. Procedures. One expert clinician from each of 44 European countries was invited to participate in an
One of the most frequently applied methods for integrating controls on primary production through satellite data is the light use efficiency (LUE) approach, which links vegetation gross or net primary productivity (GPP or NPP) to remotely-sensed estimates of absorbed photosynthetically active radiation (APAR). Eddy covariance towers provide continuous measurements of carbon flux, presenting an opp
[Context & motivation] For market-driven software product developing organizations operating on a competitive open market, it is important to plan the product’s releases so that they can reach the market as early as possible with a competitive level of quality compared to its competitors' products. Hence, quality requirements can be seen as a key competitive advantage. The QUPER model was deve
This study is based on a total cohort (N = 192) of people born in 1902 and 1903 and living in southern Sweden. Subjects were assessed at baseline when 67 years of age and on eight further occasions over 34 years or until death. The participation rate in the nine examinations ranged from 78-100%. Interviews, psychological tests, and medical examinations were used as well as information on medical d
The aim of this work is to generate detailed and simplified kinetic models for the oxidation of the Primary Reference Fuels (PRF) n-heptane, iso-octane and their mixtures, with low numbers of species and reactions. These mechanisms are consistent in terms of the choice of kinetic parameters for the different reaction classes. The further aim is to validate the kinetic models for a wide range of di
This paper reports the implementation of the SIMIND Monte Carlo code on an IBM SP2 distributed memory parallel computer. Basic aspects of running Monte Carlo particle transport calculations on parallel architectures are described. Our parallelization is based on equally partitioning photons among the processors and uses the Message Passing Interface (MPI) library for interprocessor communication a
A monogenic inheritance, mainly seen as a dominant pattern, accounts for 5 - 10% of all cancer cases. The increased knowledge and identification of high-risk genes have led to a need for specialized cancer family clinic was the expression used by Eeles and Murday. The Oncogenetic Clinic at the University Hospital in Lund was started in 1993 and the authors' 10-year experience is summarized in this
Human skin fibroblasts in different growth states were incubated with [3H]glucosamine and/or Na(2)35SO4 and extracted with Triton X-100 for various periods of time. Free heparan-sulphate oligosaccharides and protein-bound heparan-sulphate chains were separated by chromatography on octyl-Sepharose and analyzed. A pool of endogenously produced oligosaccharides, present in the cultured cells and isol
The accuracy and precision of frameless neuronavigation as compared to conventional frame-based stereotaxy for implantation of deep brain stimulation (DBS) electrodes were studied in 14 patients with essential tremor. DBS electrodes were implanted bilaterally in the ventrolateral thalamus [ventrointermediate nucleus ( VIM)] in one procedure. Frameless neuronavigation was used on one side and the c
PURPOSE: Accumulation of oxidized LDL in the arterial wall is believed to play a key role in the development of atherosclerosis. Experimental studies have identified the presence of immune responses against epitopes in oxidized LDL that protects against atherosclerosis. We have produced human recombinant IgG against one of these epitopes (aldehyde-modified apoB-100 amino acids 661-680) and demonst
