As is widely accepted, cumulative strain and improvement mechanisms of stabilized soil are critical factors for the long-term reliable operation of expressways and high-speed railways. Based on relevant research findings, xanthan gum biopolymer is regarded as a green and environmentally friendly curing agent in comparison to traditional stabilizers, such as cement, lime, and fly ash. However, little attention has been devoted to the cumulative strain and improvement mechanisms of soil reinforced by xanthan gum biopolymer under traffic loading.

A Study on the Preparation and Performance of Ultrafine Powder Made of Industrial Hemp Degumming Residue.

Polymers (Basel)

December 2024

School of Textile Science and Engineering, Wuhan Textile University, No. 1 Sunshine Avenue, Jiangxia District, Wuhan 430200, China.

Industrial hemp, one of the most widely available and extensively produced varieties, generates a substantial amount of waste in the form of hemp cellulose. This study uses a recycling method combining crushing and acid treatment to convert leftover hemp fiber into ultrafine powder. A scanning electron microscope (SEM), an atomic force microscope (AFM), Fourier transform infra-red spectroscopy (FTIR), and X-ray diffraction (XRD) were used to examine the morphology of acid-treated hemp fiber heated to 200 °C and crushed into powder.

Resuspended Nano-Minerals in Coal Ash: A Potential Factor in Elevated Lung Cancer Rates in Xuanwei and Fuyuan, Yunnan, China.

Toxics

December 2024

State Key Laboratory of Coal Resources and Safe Mining & College of Geosciences and Surveying Engineering, China University of Mining and Technology, Beijing 100083, China.

Xuanwei and the neighboring Fuyuan (XF) counties in Yunnan Province have the highest lung cancer incidence rates in China. Previous studies suggest that the nano-minerals released during the combustion of locally sourced "smoky" (bituminous) coal are the primary contributors to these elevated cancer rates. The coal ash generated during combustion predominantly consists of nano-minerals, which can be resuspended into the atmosphere during routine ash-handling activities.

Microbothriid (Monogenean) Infection and Treatment in Captive Blacktip Reef Shark ().

Microorganisms

December 2024

Laboratory of Aquatic Biomedicine, Research Institute for Veterinary Science, College of Veterinary Medicine, Seoul National University, Seoul 08826, Republic of Korea.

Unlike other microbothriid monogenean infections in elasmobranchs, limited information is available on the biology and treatment of . As parasitic infection with was found in 21 juvenile blacktip reef sharks () at the Lotteworld aquarium in Seoul, South Korea, we aimed to investigate the anatomical features and treatment protocols for in this study. The parasites were sampled and fixed in 10% neutral-buffered formalin, and examined using light and scanning electron microscopy.
