A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

open access: yesWildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Study on Electrical Properties of Silicone Rubber Insulation for Cable Accessories Under Mechanical Stretching

open access: yesHigh Voltage, EarlyView.
ABSTRACT Silicone rubber (SR) is extensively used as insulation for cable accessories, directly affecting their design and operation. The distinctive feature of cable accessory insulation, operating under mechanical stretching, has not received sufficient attention in relevant standards and research.

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

open access: yesHigh Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Oil Spill

Proceedings of SPE International Conference on Health, Safety and Environment in Oil and Gas Exploration and Production, 2000
Abstract Crude oil and refined petroleum products are mixtures of a large numbers of components, each with its own chemical and physical properties. Once oil is spilled, it immediately begins to undergo many natural physical, chemical and biological changes.

Oil Spill Environmental Forensics: the Hebei Spirit Oil Spill Case

Environmental Science & Technology, 2012
After the Hebei Spirit oil spill (HSOS) in December 2007, mixtures of three types of Middle East crude oil (total 12,547 kL) were stranded along 375 km of coastline in Western Korea. Emergency responses together with 1.3 million volunteers' activity rapidly removed ca. 20% of spilled oil but the lingering oils have been found along the heavily impacted

Oil Spill Dispersants

Pure and Applied Chemistry, 1999
Abstract Introduction: The purpose of any oil spill response is to minimise the damage that could be caused by the spill. Dispersants are one of the limited number of practical responses that are available to respond to oil spills at sea.

Deep Oil Spills

2020
The demand for oil and gas has brought exploration and production to unprecedented depths of the world’s oceans. Currently, over 50% of the oil from the Gulf of Mexico now comes from waters in excess of 1,500 meters (one mile) deep, where no oil was produced just 20 years ago. The Deepwater Horizon oil spill blowout did much to change the perception of
