Concrete production using marble powder and marble coarse aggregates: an analysis of mechanical properties and sustainability

Budownictwo i Architektura
The growing demand for concrete driven by infrastructure and urbanization puts pressure on natural resources and harms the ecosystem. Using recycled materials like waste marble powder (WMP) and marble coarse aggregates (MCA) in concrete can address this

Indigenous Futurities: Theorizing Futurity in the Past and Present

American Anthropologist, EarlyView.
ABSTRACT Over the past 20 years, a growing number of activists, scholars, writers, and visual artists have engaged with futurism as a framework for representing the lives of Indigenous peoples. Inspired by this hopeful reframing of the past‐present‐future, contributions to this special section of American Anthropologist address the question: How can ...

Retinal oxygen saturation and retinal vessel diameter in glaucoma patients before and after trabeculectomy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare retinal vessel oxygen saturations and diameters before, 1 and 3 months after trabeculectomy. Methods Retinal oxygen saturations and vessel diameters were obtained using retinal oximetry. The effect of the postoperative intraocular pressure (IOP) decrease on the arteriovenous difference (AV‐difference) was evaluated ...

Bio-deterioration of stone and concrete by Melanopsis praemorsa in Gan-HaShlosha national park—A case study

Case Studies in Construction Materials, 2020
Gan HaShlosha national park contain two ponds of running brackish water. Dams were built on the ponds in the 80 s. Some masonary from the dams, as well as other underwater structure, have deteriorated.

Envisioning the Future of Work: From Ideas to Reforms

British Journal of Industrial Relations, EarlyView.
ABSTRACT Two different theoretical perspectives concerning technology and the future of work are examined. One is linked to mainstream economics, whereas the other is associated with critical (‘post‐work’) discourse. Ideas about work—its nature and impacts on well‐being—matter in both perspectives.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Bruton tyrosine kinase (Btk) in neutrophils is indispensable for initiating and maintaining skin inflammation in a model of pemphigoid diseases

British Journal of Pharmacology, EarlyView.
Background and Purpose Bruton tyrosine kinase (Btk) is essential for B cell function. Its role in myeloid cells is less understood. Greater insights into Btk significance in myeloid cells are needed to evaluate its potential as a therapeutic target during the effector phase of antibody‐induced autoimmune diseases, where inhibiting autoantibody ...

Corporate Lobbying as Anticompetitive Behaviour in the EU

European Law Journal, EarlyView.
ABSTRACT Despite the influence of ordoliberalism in EU law, the mutual feedback between market power and political influence of dominant corporations has not become an explicit consideration in competition law enforcement and has remained rather in the background as an implicit rationale. If the threats to competition posed by regulatory capture are to
