On the independence of hydrogen production from methanogenic suppressor in olive mill wastewater

Anaerobic degradation of olive mill wastewater (OMW) at concentrations ranging from 2 to 100 g/L of chemical oxygen demand (COD) was assessed in batch assays. Methane was the main final product obtained for the lower concentrations tested. For 25 g COD/L, H2 was temporarily produced, albeit H2 depletion occurred, likely due to homoacetogenesis, since acetate was formed concomitantly. Hydrogen was produced and accumulated permanently in the assays containing 50 g COD/L of OMW. Methanogenesis and homoacetogenesis were naturally inhibited, suggesting that hydrogen recovery from OMW can be performed without the addition of methanogenic suppressors such as 2-bromoethanosulfonate. This fact opens new perspectives for the utilization of high OMW concentrations in a two-stage valorisation process combining biohydrogen and biomethane production.The authors thank the FCT Strategic Project PEst-OE/EQB/LA0023/2013, the FCT Project RECI/BBB-EBI/0179/2012, the Project "BioEnv - Biotechnology and Bioengineering for a sustainable world", REF.

Comparisons of gyrofluid and gyrokinetic simulations*

The gyrokinetic and gyrofluid models show the most promise for large scale simulations of tokamak microturbulence. This paper discusses detailed comparisons of these two complementary approaches. Past comparisons with linear theory have been fairly good, therefore the emphasis here is on nonlinear comparisons. Simulations include simple two dimensional slab test cases, turbulent three dimensional slab cases, and toroidal cases, each modeling the nonlinear evolution of the ion temperature gradient instability. There is good agreement in both turbulent and coherent nonlinear slab comparisons in terms of the ion heat flux, both in magnitude and scaling with magnetic shear. However, the nonlinear saturation level for {vert_bar}{Phi}{vert_bar} in the slab comparisons show differences of approximately 40%. Preliminary toroidal comparisons show agreement within 50%, in terms of ion heat flux and saturation level

Nanoanalytical analysis of bisphosphonate-driven alterations of microcalcifications using a 3D hydrogel system and in vivo mouse model

Vascular calcification predicts atherosclerotic plaque rupture and cardiovascular events. Retrospective studies of women taking bisphosphonates (BiPs), a proposed therapy for vascular calcification, showed that BiPs paradoxically increased morbidity in patients with prior acute cardiovascular events but decreased mortality in event-free patients. Calcifying extracellular vesicles (EVs), released by cells within atherosclerotic plaques, aggregate and nucleate calcification. We hypothesized that BiPs block EV aggregation and modify existing mineral growth, potentially altering microcalcification morphology and the risk of plaque rupture. Three-dimensional (3D) collagen hydrogels incubated with calcifying EVs were used to mimic fibrous cap calcification in vitro, while an ApoE−/− mouse was used as a model of atherosclerosis in vivo. EV aggregation and formation of stress-inducing microcalcifications was imaged via scanning electron microscopy (SEM) and atomic force microscopy (AFM). In both models, BiP (ibandronate) treatment resulted in time-dependent changes in microcalcification size and mineral morphology, dependent on whether BiP treatment was initiated before or after the expected onset of microcalcification formation. Following BiP treatment at any time, microcalcifications formed in vitro were predicted to have an associated threefold decrease in fibrous cap tensile stress compared to untreated controls, estimated using finite element analysis (FEA). These findings support our hypothesis that BiPs alter EV-driven calcification. The study also confirmed that our 3D hydrogel is a viable platform to study EVmediated mineral nucleation and evaluate potential therapies for cardiovascular calcification

Confronting the gated community: Towards a decolonial critique of violence beyond the paradigm of war

This article investigates the works of Dussel, Maldonado-Torres, and Mbembe as representatives of a tendency in the field of decolonial thought to assume the templates of warfare and the camp as the archetypal registers of violence in the contemporary world. Identifying this focus as the remnant of a Eurocentric vocabulary (the paradigm of war), the article proposes a shift from the language of warfare predominant in the field to a language of welfare. The article turns to the gated community (GC), instead of the camp, and the imperatives of (re)creation, instead of the logics of elimination, as new templates with which to make sense of modern/colonial violence. Moving beyond militaristic imagery, the analysis shows a form of violence that emerges as a response to the endless search for a life of convenience inside the walls of the GC. To this end, the article advances the concept of the dialect of disarrangement, the enforced but uneasy encounter between two subjectivities that inhabit the GC: the patrons (the homeowners who consume the easy life) and servants (the racialised service staff). In the GC, violence emerges in attempts to respond to this (in)convenient encounter via misrepresentations of both patrons and servants as out of their place

The multiple lives of affect: a case study of commercial surrogacy

This article intervenes into contemporary scholarship on affect by bringing different affect theories into the same analytical frame. Analysing commercial surrogacy in India through three different conceptualizations of affect found in the work of Michael Hardt, Sara Ahmed and Brian Massumi reveals how affect emerges as a malleable state in the practice of, as a circulatory force in the debates around, and as an ephemeral intensity in the spontaneous resistance to surrogacy. Based on this analysis, I suggest that integrating different theories of affect enables more holistic examinations of corporeal regulation by opening our understanding to the multiple lives of affect that operate on the level of political economy, cultural signification and material intensity simultaneously
