Brown–Proschan Repair Policy for Repairable Systems Using the Discrete Weibull Failure Distribution and Markov Chains

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT A repairable system operates under a maintenance strategy involving scheduled preventive maintenance (PM) and corrective repair actions following failures. This study develops an exact analytical methodology using Markov chains with discrete states and time to calculate the expected number of failures E[N(t)]$\mathop {\mathbb {E}}[N(t)]$ under

Expansion of the Brazilian Sugarcane Bioenergy System Promotes Greenhouse Emission Reductions and Sustainable Development Without Compromising Food Security

open access: yesSustainable Development, EarlyView.
ABSTRACT The growing global demand for biofuels has raised concern about compromising food security. This study uses two independent economy‐wide models to evaluate the impact of expanding the Brazilian sugarcane bioenergy system on economic growth, social outcomes and food security.

How Brazilian Public Universities Are Operationalizing The SDGs: Strategic Plans Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite the importance of universities for Sustainable Development, only a handful of studies have evaluated the implementation levels of SDGs in HEIs in Latin America. To fill this void, this study examines the strategic plans of 70 Brazilian public universities, which account for 92.8% of Federal Universities.

When Norms Meet Markets: Environmental Governance and Digital Fast‐Fashion Platforms in Brazil

open access: yesSustainable Development, EarlyView.
ABSTRACT Environmental governance increasingly relies on consumer‐based mechanisms that assume that sustainability awareness translates into purchasing behaviour. This article investigates whether such mechanisms remain effective when consumption is organised through transnational digital platforms in contexts characterised by socioeconomic inequality.

Mainstreaming Sustainability and Climate Change Across Higher Education: Lessons From Ten Pioneering Universities

open access: yesSustainable Development, EarlyView.
ABSTRACT Higher education institutions (HEIs) play a critical role in preparing graduates to address the interconnected global crises of the 21st century. Despite explicit calls from UNESCO's Education for Sustainable Development (ESD) framework (SDG 4 on quality education) and the United Nations Framework Convention on Climate Change's (UNFCCC) Action

Resonance‐Enhanced Four‐Wave Mixing Imaging for Mapping Defect Regions in Vanadium‐Doped WS2 Monolayers

open access: yesSmall Methods, EarlyView.
Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.
