TL;DR: In this paper, a Raman scattering study of wurtzite was carried out over a temperature range from 80 to 750°C, where the second-order Raman features were interpreted in the light of recent ab initio phonon density of states calculations.

TL;DR: It is shown for first time that natural N. ceranae infection can cause the sudden collapse of bee colonies, establishing a direct correlation between N. ceramice infection and the death of honeybee colonies under field conditions.

TL;DR: In this paper, the variability in composition (moisture, protein, fat, ash and total phenolics) of eight lots of spent grain supplied by a brewery was investigated.

TL;DR: The pesticide residues in stored pollen from honey bee colonies and their possible impact on honey bee losses in Spain were evaluated to determine the possible role of the most frequent and abundant pesticides and the synergism among them and with other pathogens more prevalent in Spain.

TL;DR: The method is applied to the analysis of samples from different botanical origin, which implies a solid-phase extraction on polymeric cartridges and an elution with 0.5 ml methanol to prevent matrix interference.
