Safety and efficacy of a feed additive consisting of ponceau 4R for its use in baits for freshwater fish (GIFAP).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of ponceau 4R as sensory additives (functional group: (a) colourants: (i) substances that add or restore colour in feedingstuffs). The additive is already authorised for use with cats and dogs and ornamental fish. The additive is intended to be incorporated in freshwater fishing baits up to a maximum of 15 mg/kg in complementary feed in order to colour them.

Safety and efficacy of a feed additive consisting of tartrazine for its use in baits for freshwater fish (GIFAP).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of tartrazine as sensory additive (functional group: (a) colourants: (i) substances that add or restore colour in feedingstuffs). Tartrazine is intended to be incorporated in fishing baits up to a maximum of 30 mg/kg in complementary feed in order to colour them and attract fish in freshwater (ponds, rivers), for both recreational and competitive fishing. The additive is not intended for use in aquaculture.

Mobility Gaps of Hydrogenated Amorphous Silicon Related to Hydrogen Concentration and Its Influence on Electrical Performance.

This paper presents a comprehensive study of hydrogenated amorphous silicon (a-Si)-based detectors, utilizing electrical characterization, Raman spectroscopy, photoemission, and inverse photoemission techniques. The unique properties of a-Si have sparked interest in its application for radiation detection in both physics and medicine. Although amorphous silicon (a-Si) is inherently a highly defective material, hydrogenation significantly reduces defect density, enabling its use in radiation detector devices.

Dosimetry of microbeam radiotherapy by flexible hydrogenated amorphous silicon detectors.

Detectors that can provide accurate dosimetry for microbeam radiation therapy (MRT) must possess intrinsic radiation hardness, a high dynamic range, and a micron-scale spatial resolution. In this work we characterize hydrogenated amorphous silicon detectors for MRT dosimetry, presenting a novel combination of flexible, ultra-thin and radiation-hard features.Two detectors are explored: an n-type/intrinsic/p-type planar diode (NIP) and an NIP with an additional charge selective layer (NIP + CSC).

Assessment of the feed additive consisting of endo-1,4-beta-xylanase (produced with MUCL 49755), endo-1,3(4)-beta-glucanase (produced with MUCL 49754) and polygalacturonase (produced with CBS 589.94) (AveMix® 02 CS) for weaned piglets for the renewal of its authorisation and for its extension of use to suckling piglets (AVEVE BV).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of endo-1,4-beta-xylanase (produced with MUCL 49755), endo-1,3(4)-beta-glucanase (produced with MUCL 49754) and polygalacturonase (produced with CBS 589.94) (AveMix® 02 CS/ AveMix® 02 CS L) as a zootechnical feed additive for weaned and suckling piglets. The additive is already authorised for use with weaned piglets.
