Honey bees are critical pollinators of important agricultural crops. Recently, high annual losses of honey bee colonies have prompted further investigation of honey bee infecting viruses. To better characterize the recently discovered and very prevalent Lake Sinai virus (LSV) group, we sequenced currently circulating LSVs, performed phylogenetic analysis, and obtained images of LSV2. Sequence a...

The selective catalytic oxidation (SCO) of gas phase ammonia (NH3) to nitrogen and water has been proposed as an effective ammonia removal process. This study reports that the oxidation of NH3 with oxygen to form N2 was investigated by SCO using a Pt-Rh complex catalyst that was synthesized by the incipient wetness impregnation process. The catalysts were performed using fluorescent spectroscop...

In a microbial bioelectrochemical system (BES), organic substrate such as glycerol can be reductively converted to 1,3-propanediol (1,3-PDO) by a mixed population biofilm growing on the cathode. Here, we show that 1,3-PDO yields positively correlated to the electrons supplied, increasing from 0.27 ± 0.13 to 0.57 ± 0.09 mol PDO mol(-1) glycerol when the cathodic current switched from 1 A m(-2) t...

The situation in Europe concerning honeybees has in recent years become increasingly aggravated with steady decline in populations and/or catastrophic winter losses. This has largely been attributed to the occurrence of a variety of known and "unknown", emerging novel diseases. Previous studies have demonstrated that colonies often can harbour more than one pathogen, making identification of et...

To fabricate a sustainable lithium-oxygen (Li-O2) battery, it is crucial to identify an optimum electrolyte. Herein, it is found that tetramethylene sulfone (TMS) and lithium nitrate (LiNO3) form the optimum electrolyte, which greatly reduces the overpotential at charge, exhibits superior oxygen efficiency, and allows stable cycling for 100 cycles. Linear sweep voltammetry (LSV) and differentia...

A redução eletroquímica do Furoato de Diloxanida (FD) em acetonitrila sobre um eletrodo de carbono vítreo foi estudada neste trabalho. Foi observado que o FD é reduzido após uma transferência reversível de um elétron seguida por uma reação química irreversível, diagnosticada, como uma ruptura de uma ligação C-Cl. A redução do FD foi estudada por voltametria de varredura linear (LSV), pulso dife...

Since the last decade, unusually high honey bee colony losses have been reported mainly in North-America and Europe. Here, we report on a comprehensive bee pathogen screening in Belgium covering 363 bee colonies that were screened for 18 known disease-causing pathogens and correlate their incidence in summer with subsequent winter mortality. Our analyses demonstrate that, in addition to Varroa ...

Abstract The total red shift z might be recast as a combination of the expansion and static due to energy–momentum tensor non-conservation photon propagating through Electro-Magnetic (EM) fields. If massive, may described by de Broglie–Proca (dBP) theory which satisfies Lorentz(-Poincaré) Symmetry (LoSy) but not gauge-invariance. latter is regained in Standard-Model Extension (SME), associated ...

Most existing ICP (Iterative Closet Point)-based 3D ear recognition approaches resort to the coarse-to-fine ICP algorithms to match 3D ear models. With such an approach, the gallery-probe pairs are coarsely aligned based on a few local feature points and then finely matched using the original ear point cloud. However, such an approach ignores the fact that not all the points in the coarsely seg...

INTRODUCTION This was a descriptive non-interventional study in HIV-1-infected patients treated with DRV/r conducted in the clinical setting, with a single-arm prospective design. The primary objective was to collect data on utilization of darunavir/ritonavir (DRV/r) under the conditions described in the marketing authorization. Efficacy (measured as viral load [VL] <50 copies/mL and CD4+ cell ...
