We have performed near-field x-ray imaging with simultaneous object and probe reconstruction. By an advanced ptychographic algorithm based on longitudinal and lateral translations, full-field images of nanoscale objects are reconstructed with quantitative contrast values, along with the extended wavefronts used to illuminate the objects. The imaging scheme makes idealizing assumptions on the probe

Objective: To validate the prediction model for successful vaginal birth after cesarean delivery (VBAC) based on variables easily obtainable at the first antenatal visit, in a Spanish population. Methods: Retrospective observational study. Women with a single live fetus in cephalic presentation with one previous low-transverse CD who underwent trial of labor after cesarean delivery (TOLAC) at ≥37

Kinetic model studies and control analyses of the Calvin photosynthesis cycle have been performed to characterize the dependence of the cycle activity on maximum velocities and Kmvalues for the interaction of the non‐equilibrium cycle enzymes and ATP synthetase with their substrates under conditions of light and carbon dioxide saturation. The results show that Km values have no major influence on

A novel Stacked Multi-Level (SML) modulator topology optimized for long pulse and high average power applications has been developed at ESS. It utilizes six identical modules connected in series at the HV output side and fed in parallel from the low voltage side. Each one is formed by one HF inverter, one step-up transformer, one HV rectifier bridge and one HV passive filter. They are supplied, in

Shortcomings of current techniques used for the intracerebral transplantation of ventral mesencephalic dopamine neurons include low graft survival, high variability, considerable implantation trauma and suboptimal graft integration. In order to overcome these limitations, we have adopted a microtransplantation approach which allows precise and reproducible implantation of ventral mesencephalon cel

Hydropower is a renewable energy that expected to be affected by persistent climate change in Mozambique. Variability of climate e.g. temperature and precipitation will contributors to future shortage of energy from renewable energy production especially for hydropower and biomass. This research reviews the impacts of climate change on the productions of hydropower in Mozambique. Furthermore, a st

Background: The European directive on basic safety standards (Council directive 2013/ 59 Euratom) mandates dosimetry-based treatment planning for radiopharmaceutical therapies. The directive comes into operation February 2018, and the aim of a report produced by the Internal Dosimetry Task Force of the European Association of Nuclear Medicine is to address this aspect of the directive. A summary o

Inclusive isolated-photon production in pp collisions at a centre-of-mass energy of 13 TeV is studied with the ATLAS detector at the LHC using a data set with an integrated luminosity of 3.2 fb−1. The cross section is measured as a function of the photon transverse energy above 125 GeV in different regions of photon pseudorapidity. Next-to-leading-order perturbative QCD and Monte Carlo event-gener

The Colorado potato beetle is one of the most challenging agricultural pests to manage. It has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable climates during its global invasion, and, notably, to rapidly evolve insecticide resistance. To examine evidence of rapid evolutionary change, and to understand the genetic basis of herbivory and insecticide resistance

Multiconfigurational methods are applied to study electronic properties and structural changes in the highly flexible metal-organic framework MIL53(Cr). Via calculated bending potentials of angles, that change the most during phase transition, it is verified that the high flexibility of this material is not a question about special electronic properties in the coordination chemistry, but about ove

The ATLAS experiment has performed extensive searches for the electroweak production of charginos, neutralinos, and staus. This article summarizes and extends the search for electroweak supersymmetry with new analyses targeting scenarios not covered by previously published searches. New searches use vector-boson fusion production, initial-state radiation jets, and low-momentum lepton final states,

The four-lepton (4ℓ, ℓ=e,μ) production cross section is measured in the mass range from 80 to 1000 GeV using 20.3 fb−1 of data in pp collisions at s=8 TeV collected with the ATLAS detector at the LHC. The 4ℓ events are produced in the decays of resonant Z and Higgs bosons and the non-resonant ZZ continuum originating from qq¯, gg, and qg initial states. A total of 476 signal candidate events are o

Aims. This study was primarily aimed for developing and testing a valid and reliable instrument that measures perceived threat of the risk for graft rejection after organ transplantation. A second aim was to report descriptive data regarding graft rejection and Health‐Related Quality of Life.Background. The most serious risk connected with transplantations besides infection is graft rejection.Desi

Enzymes adsorbed or deposited on porous support materials have been succesfully used as catalysts in organic media. However, the support must be chosen with great care. The support can affect the partitioning of substrates, products and water in the reaction mixture and thereby indirectly influence the catalytic properties of the enzyme. Furthermore, the support can influence both the enzyme kinet

Assembly of the mitochondrial respiratory chain requires the coordinated synthesis of mitochondrial and nuclear encoded subunits, redox co-factor acquisition, and correct joining of the subunits to form functional complexes. The conserved Cbp3-Cbp6 chaperone complex binds newly synthesized cytochrome b and supports the ordered acquisition of the heme co-factors. Moreover, it functions as a transla
