Nuclear Factor I‐B Delays Liver Fibrosis by Inhibiting Chemokine Ligand 5 Transcription

Advanced Science, EarlyView.
This study identifies the transcription factor Nuclear Factor I‐B (NFIB) as a key suppressor of liver fibrosis. NFIB expression declines during hepatic stellate cell activation, and its overexpression reduces fibrosis in mice models. The mechanism involves NFIB directly repressing chemokine C─C motif ligand 5 (CCL5), thereby alleviating oxidative ...

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

Advanced Science, EarlyView.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

Highway trial sections: Performance evaluation of warm mix asphalt and recycled warm mix asphalt

Construction and Building Materials, 2020
Abstract The present article presents the construction and evaluation of an experimental stretch of highway with environmentally sustainable mixes; warm mixes asphalt and recycled warm mixes asphalt. Six trial sections of an urban highway were constructed with different structural characteristics. Each section was 15 cm thick and 90 m long.

Warm mix asphalt: an overview

Journal of Cleaner Production, 2012
One of the causes of pollution associated with the construction of transportation infrastructures is the emission of greenhouse gases into the atmosphere. Even though the use of Warm Mix Asphalt technology has many advantages that are not related to the reduction of gas emissions, WMA technology is also good for the environment because it produces ...

Mix design and performance of warm-mix recycled asphalt

Proceedings of the Institution of Civil Engineers - Construction Materials, 2014
During recent decades, several studies have been performed on pavement recycling by using mixing temperatures that are lower than those used in traditional hot asphalt mixtures. Warm-mix recycled asphalt with bitumen emulsion is a new recycling technique that is considered a very promising solution in terms of technical, economic and environmental ...

Shanghai Experience with Warm Mix Asphalt

Paving Materials and Pavement Analysis, 2010
Warm mix asphalt (WMA) technologies have been developed to mix, transport, pave, and compact asphalt mixture at temperatures up to 40°C lower than the conventional hot-mix asphalt (HMA). The benefits of WMA include energy savings, lower CO2 emissions, and reduced workers’ exposure to fumes, reduced binder ageing, and faster release of pavement to ...

Measuring Effects of Warm-Mix Additives

Transportation Research Record: Journal of the Transportation Research Board, 2010
An emphasis on environmental stewardship has prompted the use of warm-mix technologies aimed at allowing for production of conventional asphalt mixtures at reduced temperatures. Successful use of warm-mix asphalt (WMA) in field demonstrations has created a need for development of mix design procedures.
