Heterostructures of pentacene (PEN) and buckminsterfullerene (C 60 ) are frequently attracting scientific interest as a well-defined small-molecule model system for the study of internal interfaces between two organic semiconductors. They are prototypical representatives forming a donor-acceptor combination for st
In this thesis, studies in the chemical synthesis of the dithiodiketopiperazine natural products (—)-glionitrin A and B are described.In Chapter 2, a synthesis of the indoline-fused 2,5-diketopiperazine core of glionitrin A and B using a C-H activation approach is described. The tricyclic core was prepared in only six steps and in a good overall yield (41%). In addition, the synthetic approach wa
This article discusses the politics of “direct- action” against fossil fuels put forward by climate justice movements, focusing in particular on the tactic of the blockade. Drawing on the conceptual toolkit of Urban Political Ecology, the argument moves from a critique of the consensual regime of climate change governance to highlight conflict and dissent as central forces for the transformation o
In this commentary we reflect on current labels and criteria for child language impairment from a Swedishperspective. We call for a new label highlighting the developmental, changeable and dynamic characteristics of theimpairment and discuss implications for diagnosis, assessment and research. Conceptual coherence will promotethe professional identity and status necessary for much
Searches for the lepton number violating decay and the lepton flavor violating and decays are reported using data collected by the NA62 experiment at CERN in 2017-2018. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% confidence level: , and . These results improve by 1 order of magnitude over previous results for these decay modes.
The NA62 experiment at CERN reports searches for K+→μ+N and K+→μ+νX decays, where N and X are massive invisible particles, using the 2016–2018 data set. The N particle is assumed to be a heavy neutral lepton, and the results are expressed as upper limits of O(10−8) of the neutrino mixing parameter |Uμ4|2 for N masses in the range 200–384 MeV/c2 and lifetime exceeding 50 ns. The X particle is consi
A search for the K+ → π+X decay, where X is a long-lived feebly interacting particle, is performed through an interpretation of the K+ → π+νν¯ analysis of data collected in 2017 by the NA62 experiment at CERN. Two ranges of X masses, 0–110 MeV/c2 and 154–260 MeV/c2, and lifetimes above 100 ps are considered. The limits set on the branching ratio, BR(K+ → π+X), are competitive with previously repor
The NA62 experiment at the CERN SPS reports a study of a sample of 4 × 109 tagged π0 mesons from K+ → π+π0(γ), searching for the decay of the π0 to invisible particles. No signal is observed in excess of the expected background fluctuations. An upper limit of 4.4 × 10−9 is set on the branching ratio at 90% confidence level, improving on previous results by a factor of 60. This result can also be i
Introduction: Surface Guided Radiation Therapy (SGRT) is being increasingly implemented into clinical practiceacross a number of techniques and irradiation-sites. This technology, which is provided by different vendors, canbe used with most simulation- and delivery-systems. However, limited guidelines and the complexity of clinicalsettings have led to diverse patterns of operation. With the aim to
Grunderna i cancerbehandling är kirurgi, strålterapi och behandling med cancerläkemedel, ofta i kombination med varandra. Regimer med cancerläkemedel som definierar det eller de läkemedel som används, deras doser, hur ofta och hur länge de ska ges, har utvecklats och används för olika cancerdiagnoser. Flera professioner inom sjukvården är involverade i behandlingen: läkaren som ordinerar läkemedleThe basics in cancer treatment are surgery, radiation therapy, and treatment with cancer drugs, often combined. Chemotherapy regimens that define the drugs used, the dosage, the frequency and duration of drug administration, have been developed and used for different cancer diagnoses. Several healthcare professionals are involved in the treatment: the physician prescribing the drugs, the pharmacis
PURPOSE: Learning new vocabulary has been identified as a challenge for students with (developmental) language disorder ((D)LD). In this study, we evaluate the effects of two active learning methods, (a) retrieval practice (RP) and (b) rich vocabulary instruction (RVI), in a group of students with (D)LD in secondary school.METHOD: A quasi-experimental counterbalanced within-subject design was used
Two-particle angular correlations between trigger particles in the forward pseudorapidity range (2.5 < |η| < 4.0) and associated particles in the central range (|η| < 1.0) are measured with the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV. The trigger particles are reconstructed using the muon spectrometer, and the associated particles by the central bar
Background: Accurate information about chemotherapy drugs and regimens is needed to reduce chemotherapy errors. A national e-library, as a common knowledge source with standardized chemotherapy nomenclature and content, was developed. Since the information in the library is both complex and extensive, it is central that the users can use the resource as intended.Objective: The aim of this study waBackground:Accurate information about chemotherapy drugs and regimens is needed to reduce chemotherapy errors.

Dietary factors associated with stroke risk are still rather unknown. The aim was to examine the association between adherence to healthy dietary patterns and incidence of stroke among 25,840 individuals from the Swedish Malmö Diet and Cancer Study cohort. Dietary data were obtained using a combination of a 7-day food record, diet questionnaire, and interview. A Swedish Dietary Guidelines Score (S
