Modification of aftertaste with a menthol mouthwash reduces food wanting, liking, and ad libitum intake of potato crisps [PDF]

open access: yes, 2016
This research investigated the effect of modifying the aftertaste of potato crisps on (1) temporal sensory perception and (2) appetite using three mouthwash conditions (no mouthwash, a water mouthwash, and a menthol mouthwash).

Can GNSS reflectometry detect precipitation over oceans? [PDF]

open access: yes, 2018
For the first time, a rain signature in Global Navigation Satellite System Reflectometry (GNSS‐R) observations is demonstrated. Based on the argument that the forward quasi‐specular scattering relies upon surface gravity waves with lengths larger than ...

Determination of odour concentration by TD-GC×GC–TOF-MS and field olfactometry techniques [PDF]

open access: yesMonatshefte für Chemie - Chemical Monthly, 2017
Field olfactometry is one of the sensory techniques used to determine odour concentration, in atmospheric air, directly in emission sources. A two-dimensional gas chromatography with time of flight mass spectrometer (GC×GC-TOF-MS) allows performing the chemical characterization of various groups of chemical compounds, even in complex mixtures ...

Direct measurement of molecular mobility and crystallisation of amorphous pharmaceuticals using terahertz spectroscopy. [PDF]

open access: yes, 2016
Despite much effort in the area, no comprehensive understanding of the formation and behaviour of amorphous solids has yet been achieved. This severely limits the industrial application of such materials, including drug delivery where, in principle ...

Objective and efficient terahertz signal denoising by transfer function reconstruction [PDF]

open access: yes, 2020
As an essential processing step in many disciplines, signal denoising efficiently improves data quality without extra cost. However, it is relatively under-utilized for terahertz spectroscopy.

Crystal structure and charge distribution of pyrazine: effects of extinction, thermal diffuse scattering and series termination [PDF]

open access: yes, 1976
The crystal structure and electronic charge distribution of pyrazine (1,4-diazabenzene) has been determined at 184 K by X-ray methods. The structural results of Wheatley [Acta Cryst. (1957), 10, 182-187] have been confirmed. A clear indication of bonding

Benchmarking coherent radiation spectroscopy as a tool for high-resolution bunch shape reconstruction at free-electron lasers

open access: yesPhysical Review Accelerators and Beams, 2020
We present a systematic comparison of two complementary methods for determining the longitudinal charge density profile of the compressed electron bunches in the soft x-ray free-electron laser FLASH: a frequency-domain technique—coherent transition ...
