Exploratory Analysis of Sustainable Consumption and Production Factors in Services: Insights From Four Case Studies Using Interpretive Structural Modeling

Sustainable Development, EarlyView.
ABSTRACT This study investigates how 14 sustainable consumption and production (SCP) factors interact across four service categories—Mass Service, Professional Service, Service Factory, and Service Shop—using interpretive structural modeling (ISM). ISM enables the identification and hierarchical classification of interdependencies among SCP factors in ...

Preconcentration of a Medium-Grade Celestine Ore by Dense Medium Cyclone Using a Factorial Design [PDF]

A semi-industrial scale hydrocyclone with a 250 mm internal diameter was used to concentrate medium-grade celestine ore (75%–85% celestine) from the Montevive deposit of Granada (Spain) using a dense ferrosilicon (FeSi) medium.

Simulating magnetite medium segregation in a dense medium cyclone using rheology based CFD model

, 2012
The complex nature of multi-phase flow in dense medium cyclones has restricted plant operators and designers to rely on empirical equations for predicting the performance.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Engineering Thermochemistry and Process Technologies to Enable Gigaton‐Scale Sustainable Biochar Production

SusMat, EarlyView.
This review examines large‐scale biochar production technologies and process engineering from an engineering thermochemistry perspective. At the level of thermochemical fundamentals, we discuss thermochemical techniques, pyrolysis mechanisms, and key parameters governing biochar formation.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

CFD modelling and analysis of the multiphase flow and performance of dense medium cyclone

, 2014
A computational fluid dynamics (CFD) model is proposed to describe the multiphase flow in a dense-medium cyclone (DMC). In this model, the volume of fluid (VOF) multiphase model is first used to determine the initial shape and position of the air core ...
