The valorization of Scenedesmus sp. microalgae byproducts was investigated, as a potential route for the production road binders from renewable sources. Under hydrothermal liquefaction conditions, water-insoluble viscous material obtained in ca. 55% yield, which consists an oily fatty acid-based fraction mixed with organic and inorganic solid residues (up to 22%). Although chemical composition materials completely differs that petroleum-based bitumen, similar viscoelastic properties were...

Background: Physical activity, such as running, protects against cardiovascular disease and obesity but can induce oxidative stress. Athletes often consume antioxidants to counteract the overproduction of reactive oxygen nitrogen species during exercise. Spirulina, particularly its phycocyanin content, activates Nrf2 pathway, stimulating antioxidant responses. Studies show that enhances defenses reduces inflammation, potentially improving muscle adaptation recovery. This study evaluates a...

Lipid peroxidation is associated with the development of some pathologies, such as cardiovascular diseases. Reduction in oxidative stress by antioxidants, Arthrospira (formely Spirulina), helps improving this redox imbalance. The aim study was to evaluate effect liquid extract "Spirulysat®" on markers-in particular, oxidized LDL (oxLDL)/total cholesterol-and isoprostanes and investigate its impact lipid glucose metabolism metabolic syndrome subject. A controlled, randomised, double-blind...

Abstract The introduction of gradient techniques for history matching has proved to be a useful development. Starting with an initial reservoir description the model is modified until it reproduces measured production field. It possible condition solution so that honours prior geostatistical constraints on description. This paper evaluates pilot point method obtaining these solutions and compares alternative called gradzone where groups gridcells in are modified. described here adapted from...

Summary We demonstrate how gradient-based techniques can be used to estimate uncertainty in predictive reservoir simulations made following history matching. discuss the gradient calculations help finding parameters that make largest contributions uncertainty, estimating on these parameters, and predicted quantities by use of a linear analysis. The methodology is illustrated two field examples, compared with other methods quantification.

Abstract Stable water‐in‐oil high internal phase emulsions, containing styrene and divinylbenzene monomers exfoliated montmorillonite, were prepared polymerized to obtain nanocomposite microcellular materials. The porous structure was investigated by scanning electron microscopy, mercury intrusion porosimetry, nitrogen adsorption/desorption analyses. exfoliation of clay X‐ray diffraction transmission microscopy presence inorganic filler did not modify the composite, while use modified...

Abstract Highly porous PS/DVB monoliths were prepared by polymerisation of the continuous phase a high internal emulsion. To improve mechanical properties these brittle materials, placed in presence FA vapours and adsorbed monomer was polymerised heating to create coating onto matrix surface. The influence on material structure investigated SEM, mercury intrusion porosimetry nitrogen adsorption/desorption analyses. progressive increase PFA content induced porosity decrease modification pore...

The biomass, generated after the lipid extraction from Nannochloropsis microalgae (LEM) for biodiesel production, demonstrated its suitability both energy and nutrient recovery. anaerobic digestion of LEM produced a minimum 268 mLCH4/gVS in different experiments. codigestion sewage sludge revealed that wastes can be codigested without inhibition, although no synergy was observed. methane yields barely increased 10% pretreatments (ultrasound ultrasound combined with alkali addition)....

Abstract Background Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common adverse effects antineoplastic agents, ranging in prevalence from 19% to over 85%. Clinically, CIPN a predominantly sensory that may be accompanied by motor and autonomic changes varying intensity duration. The high among cancer patients makes it major problem for both survivors, as well their health care providers, especially because there currently no single effective method preventing CIPN;...
