Open Intrameniscal Examination and Reduction of Depressed Tibial Plateau Fracture

open access: yesArthroscopy Techniques, EarlyView.
Abstract In the Schatzker classification, approximately 60.5% of tibial fractures can potentially involve depression fractures of the plateau, on average in types II, III, and IV, and are particularly prevalent among the elderly population. A significant challenge in managing these fractures is achieving optimal visualization of the depressed fracture ...

¿Indígenas o campesinos , pueblos de la selva o de la montaña? Viejos debates, nuevas perspectivas

open access: yesRevista Colombiana de Antropología, 2013
Este artículo interroga en qué medida la creación de una etnicidad genérica, producida por las movilizaciones indígenas durante las tres últimas décadas, permite superar la ruptura tradicional que existe entre pueblos indígenas de las tierras bajas y las

Comparative field‐scale assessment of TLUD and Kon‐Tiki biochar systems: agronomic performance and net CO2e‐based techno‐economics

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Nichtlineare Staubungsneigung binärer Schüttgutmischungen: Herausforderungen bei der Prognose Non‐linear dusting tendency of binary bulk material mixtures: Challenges in prognosis

open access: yesChemie Ingenieur Technik, EarlyView.
Aufgrund überlagerter oder konkurrierender Mechanismen sind relevante Wechselwirkungen bei der Staubung von Schüttgutmischungen komplex und nur unzureichend verstanden. Selbst für Mischungen aus umfassend charakterisierten Einzelkomponenten existieren keine belastbaren Modelle. In dieser Arbeit werden die Hürden bei der Prognose thematisiert.

Vergleichende Untersuchung der Eigenschaften recycelter Kohlenstofffasern Comparative investigation of the properties of recycled carbon fibers

open access: yesChemie Ingenieur Technik, EarlyView.
Die Akzeptanz recycelter Kohlenstofffasern in der Industrie erfordert eine hohe und standardisierte Faserqualität. In diesem Artikel werden mechanische Eigenschaften sowie die Oberflächenqualität neuer und recycelter Kohlenstofffasern ermittelt und verglichen, um Optimierungspotentiale für das CFK‐Recycling abzuleiten.

Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,
