The size tunable color of colloidal semiconductor quantum dots (QDs) is probably the most elegant illustration of the quantum confinement effect. As explained by the simple “particle-in-a-box” model, the transition energies between the levels increase when the “box” becomes smaller. To investigate quantum confinement effects, typically a well-defined narrow size distribution of the nanoparticles i
α-Synuclein is a synaptic protein that accumulates primarily in synucleinopathies and secondarily in certain lysosomal storage disorders. However, its physiological roles in health and disease are not fully understood. In part, this has been hampered by the inability to visualize α-synuclein and its cellular localization, due to the lack of specific antibodies and faithful reporters. Here, we used
A concept based on a combination of photofragmentation laser-induced fluorescence (PF-LIF) and two-photon laser-induced fluorescence (LIF) is for the first time demonstrated for simultaneous detection of hydrogen peroxide (H2O2) and water (H2O) vapor. Water detection is based on two-photon excitation by an injection-locked krypton fluoride (KrF) excimer laser (248.28 nm), which induces broadband f
Childhood cancer survivors (CCS) require specialized follow-up throughout their lifespan to prevent or manage late effects of cancer treatment. Knowing the size and structure of the population of CCS is crucial to plan interventions. In this scoping review we reviewed studies that reported prevalence of CCS in Europe. We searched Medline, Web of Science, and Embase using permutations of terms refe
Background: There is much interest in how the Amazon rainforest may respond to future rainfall reduction. However, there are relatively few ecosystem-scale studies to inform this debate. Aims: We described the carbon cycle in a 1 ha rainforest plot subjected to 8-10 consecutive years of ca. 50% through-fall reduction (TFR) and compare these results with those from a nearby, unmodified control plot
We study the point process given by the set of real zeros of random series generated with orthonormal bases of reproducing kernels of de Branges spaces. We find an explicit formula for the intensity function in terms of the phase of the Hermite-Biehler function generating the de Branges space. We prove that the intensity of the point process completely characterizes the underlying de Branges space

Background: The enormous potential of complex data files generated by 10-color flow cytometry (FC) is hindered by the requirement for exhaustive manual gating and the complexity of multidimensional data visualization. We propose a model using radar plots (RPs), to improve FC data visualization by capturing multidimensionality and integration of FC findings. Method: We analysed 12 normal/reactive b
To be able to disseminate knowledge about maritime safety culture and safety management to different actors in the Swedish maritime sector, a preliminary pedagogical concept was developed and evaluated. As a first user group, students at upper secondary maritime schools were chosen and the pedagogical concept was adapted for this group. The concept includes an interactive prototype and a teacher's
The development of improved biomass pyrolysis models is vital for more accurate modelling and design of biomass conversion equipment. Such improved models must be based on reliable experimental data: biomass should be pyrolyzed at high heating rates and the reaction products should be measured using an on-line, non-intrusive method. Therefore, a heated grid reactor with heating rate of 300-600 K/s
Simultaneous laser-induced fluorescence (LIF) imaging of formaldehyde and a fuel-tracer have been performed in a direct-injection HCCI engine. A mix of N-heptane and iso-octane was used as fuel and Toluene as fluorescent tracer. The experimental setup involves two pulsed Nd:YAG lasers and two ICCD cameras. Frequency-quadrupled laser radiation at 266 nm from one of the Nd:YAG lasers was used for ex
Industrial mining transforms local landscapes, including important health determinants like clean water and sanitation. In this paper, we combined macro-level quantitative and micro-level qualitative data to show how mining projects affect water infrastructures and ultimately the health of affected communities. Although we observed a positive trend of water infrastructure in mining settings, surro
We have investigated how a de novo cohort of people with Parkinson’s disease (PD) differs in terms of balance and gait function as well as frequency of near falls and falls in comparison to a cohort with mild to moderate PD that has been medicated for several years. Preliminary results (Table 1) showed that people with de novo PD have balance and gait impairments and that some have also experience
Background: The role of inflammatory and hemodynamic stress biomarkers in heart failure (HF) patients treated de novo with beta-blockers has been poorly studied. Methods: A total of 86 patients (age 56 +/- 9 years, 81 men) with left ventricular ejection fraction (LVEF) < 40% and previously not treated with beta-blockers were initiated on carvedilol. At baseline and 12 months later we performed ech
The Galactic Archaeology with HERMES (GALAH) survey is a large-scale stellar spectroscopic survey of theMilkyWay, designed to deliver complementary chemical information to a large number of stars covered by the Gaia mission. We present the GALAH second public data release (GALAH DR2) containing 342 682 stars. For these stars, the GALAH collaboration provides stellar pa
Development of concrete formulation reinforced by non-corrosive fibres, to realise thin sections. The mechanical properties were tested in the goal to evaluate an idea of application, which is a prefabricated sandwich-element integrating thermic isolation for external walls.
Wanting to help others and benefit society in one’s future career are examples of communal career goals. Raising these goals in youth should increase interest in HEED-occupations (Healthcare, Early Education, Domestic, and the Domestic fields) which are strongly gender-skewed and face labor shortage. Research has yet to find ways to increase communal career goals. In this study, we test the novel Wanting to help others and benefit society in one’s future career are examples of communal career goals.
