Thermoluminescence response of doped silicon dioxide optical fibres subjected to electron irradiation [PDF]

, 2014
This study was focused on the suitability of commercial optical fibres as a new thermoluminescence dosimeter (TLD). The materials doped to silicon dioxide(SiO2) were germanium type A (Ge (A)) of first, second and third batch, germaniumtype B (Ge (B ...

Companding technique for high dynamic range measurements using gafchromic films

, 2011
We propose a methodology to perform dose measurements using gafchromic films which can span several decades of dose levels. The technique is based on a rescaling approach using different films irradiated at different dose levels.

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

Journal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

3D‐Printed Crosslinked Nanocellulose‐MXene Hydrogels and Aerogels with High Strength and Conductivity

Small, EarlyView.
This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

Assessment of Radiation Dose to the Lens of the Eye and Thyroid of Patients Undergoing Head and Neck Computed Tomography at Five Hospitals in Mashhad, Iran [PDF]

Iranian Journal of Medical Physics, 2018
Introduction: In recent years, the number of computed tomography (CT) scans, which is a high-dose technique, has increased significantly. Head and neck CT is performed frequently and thyroid, particularly in children, has always been considered a ...

Dependence of the thermoluminescent high-temperature ratio (HTR) of LiF:Mg,Ti detectors on proton energy and dose

, 2014
The high-temperature ratio (HTR) is a parameter quantifying changes of the shape of the high-temperature part of the LiF:Mg,Ti glow-curve after exposure to densely ionizing radiation. It was introduced in order to estimate the effective LET of an unknown

Disordered Bile Acid Metabolism in Alcohol‐Related Hepatitis

Alimentary Pharmacology &Therapeutics, EarlyView.
Serum conjugated primary bile acids accumulate in alcohol‐related hepatitis due to downregulation of hepatocyte bile acid transporters. Hepatocyte growth factor is elevated in alcohol‐related hepatitis and downregulates BSEP expression. This detrimentally affects the hepatoprotective adaptive reduction in NTCP/increase in BSEP seen in cholestasis ...
