[Energy requirements of miners engaged in open-pit coal mining].

Voprosy pitaniia, 1988
It has been found that according to the value of daily energy consumption the coal miners engaged in open-cast mining should be referred to group III-IV of work intensity. The determining component of daily energy consumption is energy consumption during the working period the value of which depends on the character of working activity and duration of ...

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Mineral Oil‐Induced Ageing Characteristics of Aluminium Nitride‐Doped Silicone Rubber Nanocomposites

High Voltage, EarlyView.
ABSTRACT Room temperature vulcanised (RTV) silicone rubber, commonly used as an external insulating coating on ceramic bushings of oil‐immersed transformers, undergoes significant degradation when exposed to mineral oil under harsh environmental conditions.

Tapinarof as a Therapeutic Aryl Hydrocarbon Receptor‐Modulating Agent in the Treatment of Atopic Dermatitis

The Journal of Dermatology, EarlyView.
ABSTRACT Atopic dermatitis (AD) is a chronic inflammatory dermatitis underpinned by Type 2 inflammation driven by cytokines such as IL‐4 and IL‐13. It is characterized by skin barrier dysfunction, Th2 immune deviation, and pruritus. While biologics and oral Janus kinase (JAK) inhibitors demonstrate high therapeutic efficacy by targeting cytokines that ...

Opportunities for the Labour Party: Football, Class and Community Renewal

The Political Quarterly, EarlyView.
Abstract This article argues that football represents an underutilised opportunity for the Labour Party to anchor a wider programme of civic renewal. In many working‐class communities, the decline of trade unions, working men's clubs and other associational spaces has eroded collective life, leaving football clubs as rare institutions where dignity ...

A framework for capturing indirect impacts in site‐level screening for biodiversity risks

Methods in Ecology and Evolution, EarlyView.
Abstract Site‐based industrial operations such as mining, oil and gas extraction and renewable energy development are associated with many direct and indirect impacts on biodiversity. Consideration of the full range of these impacts when selecting a buffer distance to approximate the Area of Influence (AoI) of a project is critical for effective ...
