The formation of lumps is a common problem during powder reconstitution in food industry. If more knowledge regarding the phenomena controlling the process could be obtained, the process of industrial powder recombination could be optimized. This demands investigation of the process at three different levels: the scale of individual powder particles, the scale of powder beds, and the scale of indu
Popular Abstract in Swedish Benmärgstransplantation är idag en livsavgörande behandling som används vid leukemi, men även andra sjukdomar. Trots att behandlingen funnits sedan 1950-talet medför den fortfarande komplikationer. Den är ibland inte heller tillräckligt effektiv, och nya strategier behöver utvecklas. För att kunna genomföra detta är det av stor betydelse att förstå hur sjukdomarna uppstThe road to maturity – how do hematopoietic stem cells (HSC) differentiate into mature blood cells? The pathways of lineage commitment during normal hematopoiesis are of great significance in order to understand the underlying events that lead to leukemia, and to the design of proper treatments for prevention and remission of the disease. The route of hematopoiesis can be thought of as a hierarchi
Abstract in Undetermined A conceptually novel prosthesis consisting of a mechatronic hand, an electromyographic classifier, and a tactile display has been developed and evaluated by addressing problems related to controllability in prosthetics: intention extraction, perception, and feeling of ownership. Experiments have been performed, and encouraging results for a young transradial amputee are re
The deformed doubly magic nucleus (270)Hs has so far only been observed as the four-neutron (4n) evaporation residue of the reaction Mg-26+Cm-248, where a maximum cross section of 3 pb was measured. Theoretical studies on the formation of (270)Hs in the 4n evaporation channel of fusion reactions with different entrance channel asymmetry in the framework of a two-parameter Smoluchowski equation pre
The pathological hallmark of Parkinson’s disease is dopaminergic neurodegeneration in the substantia nigra pars compacta neurons and accumulation of α-synuclein containing aggregates in the surviving neurons. The cause of cell death in Parkinson’s disease and the involvement of α-synuclein in the pathophysiology of the disease are unknown. Although other neuronal cell types exhibit α-synuclein pos
The evidence for the existence of a chemical mechanism in surface-enhanced resonance Raman scattering (SERRS) of rhodamine 6G (R6G) adsorbed on colloidal silver excited at 1064 nm is reported on the basis of experimental and theoretical analyses. A weak absorption peak at around 1060 nm for R6G-functionalized silver nanoparticles was observed, which is not present in the individual spectra of R6G
The spatial resolution of fluorescence molecular imaging is a critical issue for the success of the technique in biomedical applications. One important method for increasing the imaging resolution is to utilize multi-photon emissions. In this study, we thoroughly investigate the potential of the multi-photon upconversion emissions from rare-earth-doped upconverting nanoparticles for the improvemen
The nuclear structure of neutron-rich N > 126 nuclei has been investigated following their production via relativistic projectile fragmentation of a E/A = 1 GeV U-238 beam on a Be target. The preliminary analysis indicates the presence of previously unreported isomeric states in the N = 128 isotones Hg-208 and Tl-209.
Even though the mammalian heart has been investigated for many years, there are still uncertainties in the fields of cardiac cell biology and regeneration with regard to exact fractions of cardiomyocytes (CMs) at different developmental stages, their plasticity after cardiac lesion and also their basal turnover rate. A main shortcoming is the accurate identification of CM and the demonstration of

Background: Polymorphonuclear neutrophils, stimulated by the activated complement factor C5a, have been implicated in cardiac ischemia/reperfusion injury. ADC-1004 is a competitive C5a receptor antagonist that has been shown to inhibit complement related neutrophil activation. ADC-1004 shields the neutrophils from C5a activation before they enter the reperfused area, which could be a mechanistic a
Purpose - The purpose of this paper is to investigate to what extent male and female PhDs choose academic vs non-academic employment. Further, it analyses gender earnings differences in the academic and non-academic labour markets. Design/methodology/approach - Rich Swedish cross-sectional register data on the stock of PhDs in 2004 is used for investigating differences between male and female PhDs
This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of
Recent developments in extremum seeking theory have established a general framework for the methodology, although the specific implementations, particularly in the context of multi-agent systems, have not been demonstrated. In this work, a group of sensor-enabled vehicles is used in the context of the extremum seeking problem using both local and global optimisation algorithms to locate the extrem
Background: Earlier studies have shown an association between secondhand tobacco smoke and allergy development in children. Furthermore, there is an increased risk of developing an allergy if the parents have an allergy. However, there are only few studies investigating the potential synergistic effect of secondhand tobacco smoke and allergic heredity on the development of an allergy. Methods: The
The dinuclear title compound, [FePtCl2(C17H14P)(C23H23NO3P)]x1.25CH2Cl2, has a slightly distorted cis-PtCl2P2 square-planar geometry around the Pt atom, and the ferrocenylphosphine ligands are staggered at an angle of 29.4 (2) deg. about Pt. In the crystal structure, the complex forms centrosymmetric dimers via two strong intermolecular O—H-O bonds resulting in R22(8) rings. A weak intramolecular
