Minimal sharing of nosematid and trypanosomatid parasites between honey bees and other bees, but extensive sharing of Crithidia between bumble and mason bees.

We document gut parasites in co-occurring Apis, Bombus, and Osmia spp. in the Northern Virginia region, USA. Trypanosomatidea occurred in sixty percent of specimens and 13% carried Nosematidae.

Clinical and radiological results of distal radioulnar joint arthroplasty with the Aptis prosthesis.

We report the results of the treatment of disorders of the distal radioulnar joint with the semi-constrained Aptis prosthesis. Nineteen patients were assessed at a mean follow-up of 7 years. All patients had been operated on previously at the wrist, forearm or elbow.

Software for the frontiers of quantum chemistry: An overview of developments in the Q-Chem 5 package.

This article summarizes technical advances contained in the fifth major release of the Q-Chem quantum chemistry program package, covering developments since 2015. A comprehensive library of exchange-correlation functionals, along with a suite of correlated many-body methods, continues to be a hallmark of the Q-Chem software. The many-body methods include novel variants of both coupled-cluster and configuration-interaction approaches along with methods based on the algebraic diagrammatic construction and variational reduced density-matrix methods.

CH Mode Mixing Determines the Band Shape of the Carboxylate Symmetric Stretch in Apo-EDTA, Ca-EDTA, and Mg-EDTA.

The infrared spectra of EDTA complexed with Ca and Mg contain, to date, unidentified vibrational bands. This study assigns the peaks in the linear and two-dimensional infrared spectra of EDTA, with and without either Ca or Mg ions. Two-dimensional infrared spectroscopy and DFT calculations reveal that, in both the presence and absence of ions, the carboxylate symmetric stretch and the terminal CH bending vibrations mix.

Relations between fruit chemical components of biquinho pepper cultivars in different crop seasons.

The species Capsicum chinense, variety biquinho, has been gaining space in cooking, but little is known about its cultivars, mainly related to the chemical composition of fruits. The objective of this study was to characterize the nutritional composition of two biquinho pepper cultivars in different growing seasons and to define the relationships between the variables and their direct and indirect effects. An experiment was conducted in a randomized block design with two cultivars of biquinho pepper, two growing seasons.
