Structural and Functional Imaging of Pancreatic Islets using Optical Coherence Microscopy

In diabetes, pancreatic beta-cells play a key role. These cells are organized within structures called islets of Langerhans inside the pancreas and produce insulin. Insulin is one of the main hormones contributing to glucose homeostasis, which is the hallm ...

Experimental tests of an advanced proton-to-neutron converter at ISOLDE-CERN

The suppression of isobaric contaminations is of growing importance for many scientific programs using radioactive isotopes produced at isotope separation on-line (ISOL) facilities, such as ISOLDE-CERN. A solid tungsten proton-to-neutron converter has been ...

Impairment of semantic memory after basal forebrain and fornix lesion

Marco Solcà

Semantic memory impairment is classically associated with lesion of the anterior temporal lobe. We report the case of a patient with severe semantic knowledge impairment and anterograde amnesia after bilateral ischemic lesion of the fornix and of the basal ...

Bulk velocity measurements by video analysis of dye tracer in a macro-rough channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Steep mountain rivers have hydraulic and morphodynamic characteristics that hinder velocity measurements. The high spatial variability of hydraulic parameters, such as water depth (WD), river width and flow velocity, makes the choice of a representative cr ...

A new transmission based monochromator for energy-selective neutron imaging at the ICON beamline

Steven Luc X Peetermans

A new type of monochromator has been developed for energy-selective neutron imaging at continuous sources. It combines the use of a mechanical neutron velocity selector with pyrolytic graphite crystals of different mosaicity. The beam can be monochromatize ...

Mathematical Modeling of Brain Energy Metabolism, Measured with PET and MRS in Rodents

Bernard Lanz

Positron emission tomography (PET) and nuclear magnetic resonance spectroscopy (MRS) are two biomedical measurement techniques developed in the end of the XXth century, which drastically improved the amount of accessible information available in vivo. PET ...

Effect of Crystallographic Phase (β vs. γ) and Surface Area on Gas Phase Nitroarene Hydrogenation Over Mo2N and Au/Mo2N

Lioubov Kiwi, Vincent Laporte, Fernando Cardenas Lizana, Daniel André Samuel Lamey

The catalytic action of Mo2N and Au/Mo2N has been assessed in the selective gas phase hydrogenation of p-chloronitrobenzene (p-CNB) to p-chloroaniline (p-CAN). The nitrides were synthesised via temperature programmed treatment of MoO3 in H-2 + N-2 and Au i ...

Carbon monoxide as a tracer of gas transport in snow and other natural porous media

Wolf Hendrik Huwald, Marc Parlange, Marc Calaf Bracons, Nicolaas Cornelis van de Giesen, Scott W. Tyler

The movement of air in natural porous media is complex and challenging to measure. Yet gas transport has important implications, for instance, for the evolution of the seasonal snow cover and for water vapor transport in soil. A novel in situ multi-sensor ...

A Compact Probe for Beta+Emitting Radiotracer Detection in Suregery, Biopsy, and Medical Diagnostics based on Silicon Photomultipliers

Edoardo Charbon, Claudio Bruschini, Marco Matter, Christian Mester

We present a new probe for radiotracer detection in vivo. The device is based on silicon photomultipliers coupled with a scintillator and wirelessly compensated for supply voltage and temperature variations. The probe is positron sensitive. ...

A Handheld Probe for beta(+)-Emitting Radiotracer Detection in Surgery, Biopsy and Medical Diagnostics based on Silicon Photomultipliers

Edoardo Charbon, Claudio Bruschini, Christian Mester

We present a new, handheld probe for radiotracer detection in vivo and inside operating theatres, where PET scanners cannot be used for radioguided surgery. The device is based on scintillation detectors optically coupled to Silicon Photomultipliers (SiPMs ...
