Hybrid HBT oscillator and mixer [PDF]

, 1990
The HBT presents inherent low 1/f noise characteristic, which makes HBT a very promising candidate, compared to GaAs MESFET or Silicon BJT, for these high frequency low phase noise applications [1,2,3].

Excited‐State Antiaromaticity in Nonbenzenoid Aromatics: Examining the Dynamics of Intramolecular Proton Transfer With a Small Driving Force

Angewandte Chemie, EarlyView.
The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.

Hydrography rather than lip morphology better explains the evolutionary relationship between Gymnogeophagus labiatus and G. lacustris in Southern Brazil (Cichlidae: Geophagini)

Neotropical Ichthyology, 2021
Gymnogeophagus labiatus and G. lacustris have been long recognized as sister species exhibiting different ecological requirements. Gymnogeophagus labiatus occurs in rock bottom rivers in the hydrographic basins of Patos Lagoon (HBP) and Tramandaí River ...

Conjunctival Myxoma: Series of Three Cases of a Rare Ocular Tumour [PDF]

Journal of Clinical and Diagnostic Research, 2022
Conjunctival myxomas are very rare benign tumours of mesenchymal origin which pose a diagnostic challenge clinically and radiologically. They usually present as asymptomatic slowly growing cystic lesions involving the bulbar conjunctiva.

The Effect of Adding Corn Silage at Different Ratios to Orange and Tangerine Wastes on Biogas Production Efficiency

Journal of Agricultural Sciences, 2018
In this study, biogas production efficiencies of mixtures obtained by adding corn silage (CS) to citrus industrial wastes at different ratios were determined. Orange (OJPW) and tangerine processing juice wastes (TJPW) (crusts and shells) were selected as
