Integrated pretreatment and fermentation strategies for L‐lactic acid production from brewers' spent grain using native Streptococcus infantarius and Bacillus coagulans

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 9, Page 1869-1876, September 2026.
Abstract BACKGROUND Brewers' spent grain (BSG) is an abundant lignocellulosic byproduct of the brewing industry with strong potential as a renewable substrate for biotechnological production of lactic acid (LA). This study evaluated integrated pretreatment, enzymatic hydrolysis, and fermentation strategies to enable efficient production of optically ...

When Illness Becomes Debt: Catastrophic Health Expenditures and Financial Distress—Evidence From India's Healthcare System

World Medical &Health Policy, Volume 18, Issue 3, September 2026.
ABSTRACT This study examines the association between catastrophic health expenditure (CHE) and distress financing among India's uninsured “missing middle,” a population largely excluded from public insurance schemes and private coverage. While healthcare‐induced financial hardship is well documented, evidence on subsequent coping strategies among this ...

Previsão em tempo real do output brasileiro na presença de quebras estruturais: comparação de modelos lineares e não-lineares [PDF]

, 2002
Neste artigo são comparadas as habilidades preditivas de modelos lineares e não lineares, com quebras estruturais, para a taxa de crescimento do PIB do Brasil. São estimados os modelos com mudança de regime markoviana propostos por Hamilton (1989) e Lam (

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Climatic and Hydrological Changes Drive Contemporary Fire Regime Transitions in the World's Largest Wetland

Global Change Biology, Volume 32, Issue 9, September 2026.
Long‐term fire data (1985–2024) and integrated modeling reveal a climate and hydrology‐driven transition toward larger fires, increased burned area, and a longer fire season, indicating the emergence of a new fire regime in the Pantanal. ABSTRACT Tropical wetlands have historically been resilient to fire, but ongoing climate and hydrological changes ...

Técnica de identificação de modelos lineares e não-lineares de séries temporais

, 2017
In this work, an algorithm for identifying time series models is proposed. The strategy is based on Partial Mutual Information Criterion (PMI), which considers not only linear but also non-linear relations between variables under study.
