Aquaporins: Another piece in the osmotic puzzle
(Elsevier Science, 2012-09)
Osmolarity not only plays a key role in celluar homeostasis but also challenges cell survival. The molecular understanding of osmosis has not yet been completely achieved, and the discovery of aquaporins as molecular ...
Constructed wetlands as an alternative for arsenic removal from reverse osmosis effluent
(Elsevier, 2019-11-15)
In Argentina, drinking water for c.a. 10% of the population has arsenic (As) concentrations higher than those recommended by WHO (10 μg L−1). Reverse osmosis (RO) appears as an immediate and effective solution for As ...
Improvements of a hollow fiber reverse osmosis desalination model: Analysis of numerical results
(Elsevier, 2010-07)
In this work, a rigorous model describing the processes taking place in hollow fiber modules for reverse osmosis desalination is analyzed. The Kimura-Sourirajan model is used for describing transport phenomena through the ...
Challenges on Optical Printing of Colloidal Nanoparticles
(American Institute of Physics, 2022-01)
While colloidal chemistry provides ways to obtain a great variety of nanoparticles with different shapes, sizes, material composition, and surface functions, their controlled deposition and combination on arbitrary positions ...
An experimental approach to evaluate osmosis and tonicity on white blood cells by flow cytometry for biomedical physiology students
(Inst Biology, 2021-06-29)
Flow cytometry has become an important tool in the fields of veterinary, medicine, and biological sciences in general. However, in the introductory and even in advanced university degree courses, students do not have many ...
Fluid transport across leaky epithelia: Central role of the tight junction and supporting role of aquaporins
(American Physiological Society, 2010-10)
The mechanism of epithelial fluid transport remains unsolved, which is partly due to inherent experimental difficulties. However, a preparation with which our laboratory works, the corneal endothelium, is a simple leaky ...
Physico-chemical treatment for the degradation of cyanotoxins with emphasis on drinking water treatment - How far have we come?
(Elsevier, 2018-08)
Over the years, various physicochemical treatment processes, such as photocatalysis, membrane technology, ozonolysis and chlorination have been tested at laboratory and pilot scale for the treatment of various cyanotoxins. ...
Asymmetry in osmotic response of cortical collecting duct cells: Role of Aquaporin-2
(Springer, 2005-10)
Transition from antidiuresis to diuresis exposes cortical collecting duct cells (CCD) to asymmetrical changes in environment osmolality, inducing an osmotic stress, which activates numerous membrane-associated events. The ...
Respuestas de geófonos a campos electromagnéticos
(Asociación Argentina de Geofísicos y Geodestas, 2010-03)
La electro-ósmosis es el fenómeno físico por el cual una variación de potencial eléctrico, da lugar a una circulación de fluido. El fenómeno recíproco que genera una corriente eléctrica a partir de un gradiente de presión ...
Current Trends on Role of Biological Treatment in Integrated Treatment Technologies of Textile Wastewater
(Frontiers Media, 2021-02)
Wastewater discharge is a matter of concern as it is the primary source of water pollution. Consequently, wastewater treatment plays a key role in reducing the negative impact that wastewater discharge produce into the ...
