Biomass Inertization to Increase Minimum Ignition Temperature

Journal of Loss Prevention in the Process Industries, 2023
In the past years, the use of biomass has significantly increased and, therefore, so has the number of accidents related to its storage, transport, and use. To prevent these accidents, it is essential to properly know their flammability and explosion characteristics so their behaviour can be addressed as a first stop for preventing accidents.

Minimum Net Driving Temperature Concept for Membrane Distillation [PDF]

Membranes, 2020
In this study, we analyzed the heat requirement of membrane distillation (MD) to investigate the trade-off between the evaporation efficiency and driving force efficiency in a single effect MD system. We found that there exists a non-zero net driving temperature difference that maximizes efficiency.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Significantly lower summer minimum temperature warming trend on the southern Tibetan Plateau than over the Eurasian continent since the Industrial Revolution

Environmental Research Letters, 2019
Summer temperature dominates environmental degradation and water resource availability on the Tibetan Plateau (TP), affecting glacier melting, permafrost degradation, desertification and streamflow, etc.

Análise dos quantis da temperatura mínima no Rio Grande do Sul e ligações com os setores da Concentração de Gelo Marinho Antártico Quantiles analisys of minimum temperature in Rio Grande do Sul and relationships with the antarctic sea ice concentration sectors

Revista Brasileira de Meteorologia, 2011
A Antártica tem papel relevante no domínio da circulação atmosférica e oceânica devido às mudanças sazonais consideráveis na concentração de gelo marinho. Há importante modificação sazonal nas dimensões do gelo que circunda seu continente.

Effects of meteorological variables on sugarcane ripening in the Cauca river valley, Colombia

Pesquisa Agropecuária Tropical, 2020
Sugarcane ripening is conditioned by the interaction between biological factors of the crop and climate. This study aimed to evaluate the effects of some meteorological variables on the sucrose content, during the ripening period, in the Cauca river ...

The Relation between the Radial Temperature Profile in the Chromosphere and the Solar Spectrum at Centimeter, Millimeter, Sub-millimeter, and Infrared Wavelengths

, 2014
Solar observations from millimeter to ultraviolet wavelengths show that there is a temperature minimum between photosphere and chromosphere. Analysis based on semi-empirical models locate this point at about 500 km over the photosphere.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
