Highly sensitive refractometer with photonic crystal fiber long-period grating
, 2007 We present highly sensitive refractometers based on a long-period grating in a large mode area PCF. The maximum sensitivity is 1500 nm/RIU at a refractive index of 1.33, the highest reported for any fiber grating.

Journal of Phycology, EarlyView.Abstract Despite the importance of the seasonal timing of events in the life cycle for understanding population dynamics, we lack information on the phenology of most macroalgal species. The red macroalga Gracilaria vermiculophylla has become common in both hard‐ and soft‐bottom habitats following its invasion throughout the Northern Hemisphere.

Psychogenic polydipsia in dogs – a review of pathogenesis, diagnosis and treatment
Journal of Small Animal Practice, EarlyView.Polyuria and polydipsia represent a common clinical presentation in dogs and may result from numerous disorders affecting different body systems. Compulsive water consumption is characteristic of psychogenic polydipsia, a primary polydipsia disorder rooted in neurologic, behavioural or environmental factors.

Use of clinic refractometer at farm as a tool to estimate the IgG content in goat colostrum
Journal of Applied Animal Research, 2018 Refractometry has been proposed as a farm technique to estimate the IgG concentration in colostrum. In order to validate the method in goat colostrum using a clinical refractometer, 216 colostrum and milk samples were obtained from 54 dairy goats ...

Integrated temperature compensated Bragg grating refractometer
UV written planar Bragg grating sensors have been shown to form effective refractometers. Here we show that by using the birefringence of an integrated waveguide a temperature insensitive Bragg grating refractometer can be ...

Reduced snow cover at the alpine treeline: resistance and recovery of saplings
New Phytologist, EarlyView.Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Plant Biotechnology Journal, EarlyView.ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).
