A simple model based on rapid‐equilibrium assumptions is derived which relates the steady‐state activity of the Calvin cycle for photosynthetic carbohydrate formation in C3 plants to the kinetic properties of a single cycle enzyme (fructose bisphosphatase) and of the phosphate translocator which accounts for the export of photosynthate from the chloroplast. Depending on the kinetic interplay of th
Light-by-light scattering (γγ → γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic field strengths generated by ultra-relativistic colliding lead ions. Using 480 μ1 of lead-lead collision data recorded at a centre-of-mass energy per nucleon pair of 5.02 TeV by
Computed tomography (CT) is a widespread diagnostic modality that is commonly associated with relatively high patient doses. Hence, optimization of radiation protection of the patients from CT examinations is extremely important. An integrant part of radiation protection in medicine is a system of diagnostic reference levels (DRLs). The aim of the study was to evaluate the possibility of establish
One year ago, we discovered a new family of insect RYamide neuropeptides, which has the C-terminal consensus sequence FFXXXRYamide, and which is widely occurring in most insects, including the fruitfly Drosophila melanogaster and the red flour beetle Tribolium castaneum (F. Hauser et al., J. Proteome Res. 9 (2010) 5296-5310). Here, we identify a Drosophila G-protein-coupled receptor (GPCR) coded f
Molecularly imprinted polymers are prepared using various steroid compounds as the templates. The imprinted polymers can selectively re-bind the original print molecules, which leads to versatile potential applications. The feasibility of using these artificial receptors to replace their biological counterparts for preliminary screening of a chemical library is demonstrated. A steroid library comp
Voices today from the eighties – constructing peaceful citizensThe increased interest for questions of survival, focused in the fear for a nuclear war, also became the start for university courses and of Action research both in public schools, in Teacher Education and in the Universities in Sweden. The article is arguing that there are roots back to the 1960s and a continuity within Peace Educatio
Building the European Spallation Source (ESS), the most powerful neutron source in the world, requires significant technological advances at most fronts of instrument component design. Detectors are not an exception. The existing implementations at current neutron scattering facilities are at their performance limits and sometimes barely cover the scientific needs. At full operation the ESS will y
In this paper some of the numerical problems associated with computing the generalized inverse of a matrix are discussed and illustrated by a detailed analysis of an iteration of Ben-Israel and Cohen.
With data from two comparable corpora of spoken British English, the London-Lund Corpus and the new London-Lund Corpus 2, this study tracks the development of the reactive what-x construction half a century back in time. The study has two goals: (i) to describe the uses of the construction over time and (ii) to establish the motivations and mechanisms related to its development in spoken dialogue.
The phase diagram of the Al–B–C system has been calculated at pressure 7.7 GPa using models of the phenomenological thermodynamics with the interaction parameters derived from the experimental data on the phase equilibria at high pressures and temperatures.
Magnetic resonance spectroscopy (MRS) is a non-invasive technique that can be used to detect and quantify multiple metabolites. This chapter will review some of the applications of MRS to the study of brain functions. Typically, (1)H-MRS can detect metabolites reflecting neuronal density and integrity, markers of energy metabolism or inflammation, as well as neurotransmitters. The complexity of th
A set of successively more accurate self-consistent equations for the one-electron Green's function have been derived. They correspond to an expansion in a screened potential rather than the bare Coulomb potential. The first equation is adequate for many purposes. Each equation follows from the demand that a corresponding expression for the total energy be stationary with respect to variations in
Chlorophyllide a is a metabolite late in the biosynthesis of chlorophylls and bacteriochlorophylls. Isolation procedures for chlorophyllide a from Rhodobacter capsulatus CB1200 and barley (Hordeum vulgare L.) are described and compared. R. capsulatus CB1200 is a double mutant in the bacteriochlorophyllide a biosynthetic pathway, and chlorophyllide a is excreted by the cells when grown in Tween 80-
The objective was to estimate the cost-effectiveness of TNF-inhibitors for the treatment of rheumatoid arthritis in Swedish clinical practice, both as a first and second biological treatment, with or without the combination of conventional DMARDs. Further sub-group analysis of etanercept treatment was performed. Patient level data were obtained from three regions of the Swedish Rheumatology Regist
