Comprehensive echocardiographic imaging of atrioventricular valves in children with atrioventricular septal defect : Accuracy of 2D and 3D imaging and reasons for disagreement

OBJECTIVE: To compare the accuracy and reasons for disagreement of two-dimensional (2D) and three-dimensional (3D) echocardiography findings in the assessment of the atrioventricular valve complex in patients with atrioventricular septal defect. METHODS: A total of 20 children (mean age 8 months) with atrioventricular septal defect were enrolled prospectively into this study. The accuracy of and t

Non-binary phase gratings for x-ray imaging with a compact Talbot interferometer

X-ray imaging using a Talbot-Lau interferometer, consisting of three binary gratings, is a well-established approach to acquire x-ray phase-contrast and dark-field images with a polychromatic source. However, challenges in the production of high aspect ratio gratings limit the construction of a compact setup for high x-ray energies. In this study we consider the use of phase gratings with triangul

Out-of-hospital cardiac arrest at place of residence is associated with worse outcomes in patients admitted to intensive care : a post-hoc analysis of the Targeted Temperature Management trial

BACKGROUND: The majority of out-of-hospital cardiac arrests (OHCAs) occur at place residence, which is associated with worse outcomes in unselected prehospital populations. Our aim was to investigate whether location of arrest was associated with outcome in a selected group of initial survivors admitted to intensive care.METHODS: This is a post-hoc analysis of the Targeted Temperature Management a

Geochemical composition of Baltic benthic foraminifera collected and cultured over a large salinity gradient.

Some of the most significant challenges in paleoclimate research arise from the need to both understand and reduce the uncertainty associated with proxies for climate reconstructions. These challenges were further highlighted in connection with the IODP Exp.347 Baltic Sea Paleoenvironment. We have investigated temperature and salinity proxies through a combination of field-and culture-based benthi

Inorganic Ions Assisted Anisotropic Growth of CsPbCl3 Nanowires with Surface Passivation Effect

All-inorganic halide perovskite nanowires (NWs) exhibit improved thermal and hydrolysis stability and could thus play a vital role in nanoscale optoelectronics. Among them, blue-light-based devices are extremely limited because of the lack of a facile method to obtain high-purity CsPbCl3 NWs. Herein, we report a direct and facile method for the synthesis of CsPbCl3 NWs assisted by inorganic ions t

Surface Engineering of Quantum Dots for Remarkably High Detectivity Photodetectors.

Ternary alloyed CdSexTe1–x colloidal QDs trap-passivated by iodide-based ligands (TBAI) are developed as building blocks for UV–NIR photodetectors. Both the few surface traps and high loading of QDs are obtained by in situ ligand exchange with TBAI. The device is sensitive to a broad wavelength range covering the UV–NIR region (300–850 nm), showing an excellent photoresponsivity of 53 mA/W, a fast

Skjutvapens- och explosionsvåld

Det skjutvapenrelaterade våldet i Sverige har ökat kraftigt sedan 1990-talet, och trots att hela Sverige är drabbat sticker Region Skåne och då främst Malmö ut. Även om en stor del av skottlossningarna riktas mot byggnader och fordon dör och skadas årligen ett tiotal personer i staden. Även explosionsvåldet har ökat både i landet och i Malmö och det kan vara ett tecken på ett trendbrott inom den gGun-related violence in Sweden has increased dramatically since the 1990s, and while the entire country has been affected, the Skåne region and Malmö in particular stand out. Although many of the shootings are directed at buildings and vehicles, more than ten people are killed and injured in the city every year. Violence caused by explosives has also increased both in Malmö and in the country as a

Gärningsmannen, brottet och offret

Förutom att Malmö har flest anmälda brott i relation till sin folkmängd, är det också en av de städer i landet med högst andel skjutvapenrelaterat våld. Våra tidigare studier visar att de som begår grova brott som mord eller dråp och försök till mord eller dråp i Malmö främst är ensamstående, har ingen psykiatrisk diagnos och använder sig främst av kniv eller annat vasst tillhygge vid sina dåd, ävIn addition to Malmö having the most reported crimes in relation to its population, it is also one of the cities in the country with the highest percentage of gun-related violence. Our earlier studies show that people who commit serious crimes such as homicide or attempted homicide in Malmö are primarily single, have no psychiatric diagnosis and mainly use knives or other sharp weapons to commit t

Brottslighet och utsatthet i Malmö

Malmö stad och dess invånare rör sig i en historisk tid och i en föränder­­lig miljö: sedan 1990 har staden vuxit med 43 procent. I Brottslighet och utsatthet i Malmö presenteras ett axplock av aktuell forskning, dess tillämpning och den påverkan som brottsligheten och utsattheten har och har haft på Malmö sedan början av 2000-talet.Brottslighet och utsatthet i Malmö tar upp ämnen som skjutvapens-Malmö and its inhabitants are living in a historical era and in a changing environment – in a city that has grown with 43 percent since 1990. Crime, Victimization and Vulnerability in Malmö presents a selection of current research, and the impact that crime, victimization and vulnerability have had on Malmö since the early 2000s.Crime, Victimization and Vulnerability in Malmö addresses topics such

Direct observation of the atomic force microscopy tip using inverse atomic force microscopy imaging

It is a well‐known fact in scanning probe microscopy that the tip geometry will be convoluted with the shape of the sample. In this study we report on a clear‐cut in situ direct observation of the real shape of the atomic force microscopy (AFM) tip using the AFM technique itself, utilizing a specially designed sample. The sample was an array of columns fabricated using aerosol deposition of metal
