Recent data give unexpectedly large cross-sections for charmed particle production at high xF in hadron collisions. This may imply that the proton has a non-negligible uudcc Fock component. The interesting consequences of such a hypothesis are explored.

BACKGROUND: Carcinoids are rare indolent neuroendocrine tumors, mainly located in bowel, stomach, and lung. Their etiology is virtually unknown although a family history is a minor cause.METHODS: Site specific incidence trends and several risk factors of carcinoid tumors were studied based on the nationwide Swedish Family-Cancer Database of 10.2 million individuals and their more than 1 million tu

Since the popular uprising and subsequent war in Syria in 2011, more than a quarter of its population have fled – mainly to Turkey, Lebanon, Jordan, Iraq and Egypt – and another 25% have been internally displaced. The end of 2017 saw 12.6 million Syrians forcibly displaced – 6.3 million refugees, 6.2 million internally displaced (IDPs) and 146,700 asylum-seekers. In the words of the United Nations

What does dignity mean to Syrian refugees and practitioners? And what can humanitarian organisations do – or abstain from doing – to help Syrians preserve and protect their dignity?

Background Functional data is data represented by functions (curves or surfaces of a low-dimensional index). Functional data often arise when measurements are collected over time or across locations. In the field of medicine, plasma lipoprotein particles can be quantified according to particle diameter by ion mobility. Goal We wanted to evaluate the utility of functional analysis for assessing the

Atmospheric concentrations of molecular hydrogen are commonly measured with the aid of commercial reduction gas analysers (RGA). An alternative technique of H2 detection has been proposed and tested. It is based on commercial automated gas chromatograph equipped with a μ-ECD detector doped with N2O. The main advantage of the presented method is its suitability for high-precision monitoring of atmo

The formation of a hybrid composite material consisted of polymer brushes and phenylboronic acid ligands on a macroporous cryogel is reported here for the first time for effective adsorption of glycoprotein and yeast cells. The surface area of the cryogel was increased by covalent immobilization of silica nanoparticles. Random copolymer brushes composed of N-isopropylacrylamide and glycidyl methac

Renovating and improving the current building stock is a matter of both need and importance. In order to know if the implemented renovation measure has had an impact on the building as a system it is important to verify the impact through measurements. The aim of this project is to isolate the impact of a measure on the energy efficiency of a building as well as the indoor environmental quality. T

Literature investigating highly skilled Chinese migrants has so far focused on their role as drivers of new entrepreneurship as well as innovation in firms and regions, although their role in supporting small and medium enterprises' (SMEs) engagement in global innovation networks (GINs) is still underexplored. The participation in GINs is a key for high-tech SMEs, which rely on sophisticated knowl

Bioreduction has emerged over the years as an alternative method to organic synthesis for the generation of chiral precursors of commercial interest. Bioreductions operate under mild conditions of pH and temperature with the help of highly regio- and enantio-selective oxidoreductase enzymes.In this contribution, the different oxidoreductase families involved in bioreductions are exemplified and th
