Producción de sulfato de cobre pentahidratado a partir de cemento de cobre

Revista del Instituto de Investigación de la Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica, 2005
In the south part of the country there oxidated copper minerals hard to leach and when you do it you get extracts are rich in copper but also contain polliting agents, that produces copper sulfate that does not match with the technical characteristics requiered for its industry use.

S100A8/A9 Drives Emergency Granulopoiesis to Promote Triple‐Negative Breast Cancer Metastasis

iNew Medicine, EarlyView.
ABSTRACT Objective Triple‐negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by high metastatic potential and limited therapeutic options. Although neutrophils contribute to tumor progression, how tumors systemically regulate neutrophil production remains poorly understood.

Metal Accumulation, Liver Histopathology, and Human Health Risk Assessment Across Different Trophic Guilds in a Mining‐Affected Neotropical River

Journal of Applied Toxicology, EarlyView.
ABSTRACT Metal pollution in aquatic environments represents a recurring global concern; however, traditional paradigms often assume linear bioaccumulation patterns that may fail under catastrophic contamination scenarios. This study evaluated metal concentrations in water, sediment, and tissues of 10 fish species from different trophic guilds in the ...

Distinct Conformational Switches Control WPD‐Loop Dynamics Across Protein Tyrosine Phosphatase Subfamilies

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Protein Tyrosine Phosphatases (PTPs) regulate cellular signaling by balancing phosphotyrosine levels through a conserved WPD‐loop that switches between open (inactive) and closed (active) conformations. While this conformational change is crucial for catalysis, the structural factors governing this motion remain poorly understood.

Social Sustainability in Circular Bioeconomy Business Models: Insights From Argentina

Sustainable Development, EarlyView.
ABSTRACT Research on circular bioeconomy business models (CBEBM) has largely prioritised environmental and economic aspects, leaving out the social pillar. To address this gap, this paper analyses to what extent and in what ways social sustainability is integrated into CBEBM, based on 12 cases from northern Argentina, a region with high potential for ...
