Preparation and characterization of thermal neutron sensitive lithium doped polystyrene plastic scintillators

He jishu
BackgroundLithium-doped plastic scintillators possess the dual-mode detection capability for both fast and thermal neutrons, and combine the advantages of conventional plastic scintillators such as cost-effectiveness and the ability to fabricate in large

Exposure to Structurally Related Organophosphate Esters Elicits Distinct Metabolomic Perturbations in Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Organophosphate esters (OPEs) are found ubiquitously in the environment and exposure to these chemicals has induced behavioral, developmental, and morphological impairments in several model organisms. Yet there is still a lack of understanding of how sub‐lethal exposure disrupts organism function at the molecular‐level, especially for Daphnia ...

Integrated Alpha–Gamma Radiation Exposure From Natural Radionuclides in Cement and Gypsum Production: Implications for Occupational Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Natural radionuclides in cement and gypsum production materials pose significant risks of occupational radiation exposure that are not well documented in Iraqi Kurdistan. This study quantifies alpha and gamma radiation levels from naturally occurring radioactive materials, specifically 222Rn, 238U, 232Th, and 40K, in cement and gypsum samples ...

Plastic scintillator bar with WLS fiber calorimeter for neutrino physics

, 2001
A calorimeter with 180 plastic scintillator bars interleaved with 180 iron bars has been built and tested with pion and electron beams at CERN. The plastic scintillator bars, coupled to wavelength shifting fibers, are read with multi-anode PMTs and ...

Light Element Dilution Effects on Fused Borate Glass Bead Specimens for X‐Ray Fluorescence Analysis of Igneous Rock Samples

X-Ray Spectrometry, EarlyView.
ABSTRACT Appropriate sample‐to‐flux ratios of fused borate glass bead specimens were investigated for igneous rock analyses. Severe interference of X‐ray absorption and enhancement engenders erroneous findings from X‐ray fluorescence spectrometric analyses, but light element dilution effects on glass bead specimens decrease this interference.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, Volume 138, Issue 46, 9 November 2026.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

“Why?”: C. Wright Mills on the Spirit of the Classical Sociological Tradition and Positivist Versus Critical Sociology

Sociology Lens, EarlyView.
ABSTRACT Despite their very diverse interests, the classical sociological thinkers were concerned with analyzing the dramatic social transformations in the wake of colonialism, slavery, and modern industrial capitalism as well as the multiple revolutions, particularly in relation to the new forms of social inequalities and power disparities.
