The properties of two new lipophilic isomeric phthalocyanines 2,9(10),16(17),23(24)-tetrakis-[(2-dimethylamino)ethylsulfanyl] phthalocyaninatozinc(II) (Pc9) and 1,8(11),15(18),22(25)-tetrakis[(2- dimethylamino)ethylsulfa...

The widely distributed pollutant tributyltin (TBT) was analyzed in different environmental samples (waters and sediments) combining preconcentration on a nylon membrane, excitation–emission fluorescence matrices direct...

The objective was the design and the structural and functional characterization of bioactive compounds (BC) as functional food ingredients for a future industrial application in chocolate milk. Liposomes were made of soy...

A simple and fast capillary electrophoresis method has been developed to determine the amount of piroxicam loaded in a drug delivery system based on nanostructured lipid carriers (NLC). The entrapment efficiency of the n...

The therapeutic benefit of phosphorothioate oligodeoxynucleotides (PS-ODN) containing immune stimulatory sequences has been demonstrated in animal models of cancer and infection. Several tools are available for the deter...

Fighting fires is a very risky job, where loss of life is a real possibility. Proper training is essential. Several firemen academies offer courses and programs whose goal is to enhance the ability of fire and emergency ...

Pseudomonas putida A (ATCC 12633) were encapsulated in Ca-alginate and their ability to degrade the quaternary ammonium compounds (QACs) tetradecylbenzyldimethylammonium chloride (C14BDMA), hexadecylbenzyldimethylammoniu...

In the present work, density functional theory (DFT) calculations using cluster and slab models were performed in order to study the adsorption of Al dimer on a monovacancy of graphene. With cluster models, two different...

In this work, the characteristics of a commercial sample of LaNi5 are compared to those of an experimental one obtained by mechanical alloying followed by low temperature annealing. The nominal composition of the experim...

Homogenizationmodels are widely used to predict the evolution of texture (crystal preferred orientations) and resulting anisotropy of physical properties in metals, rocks, and ice. They fail, however, in predicting two m...

Soy protein isolate (SPI) films reinforced with starch nanocrystals (SNC) were developed by simple casting method. The films were transparent and homogeneous. The opacity and degree of crystallinity increased with the am...

A new environmental friendly methodology based on fluorescent signal enhancement of rhodamine B dye is proposed for Pb(II) traces quantification using a preconcentration step based on the coacervation phenomenon. A catio...

The use of solid fermentation substrate (SSF) has been appreciated by the demand for natural and healthy products. Lactic acid bacteria and bifidobacteria play a leading role in the production of novel functional foods ...

Sugarcane weevil borer, Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae) has been detected across all sugarcane planting areas in the Argentinian Northwest with increasing population densities. The monito...

The cell wall polysaccharides from Codium decorticatum and their assembly were studied and these results were compared with those obtained previously for this genus. The water soluble polysaccharides are: i) Pyruvylated ...

Progesterone has long been linked to breast cancer but its actual role as a cancer promoter has remained in dispute. Previous in vitro studies have shown that progesterone is converted to 5a-dihydroprogesterone (5aP) in ...

Ranching is a challenging and sometimes risky business, with cattle production (and associated enterprise income) largely being dependent on seasonal weather patterns and corresponding forage production. To help reduce t...

The quantitative contribution of shoot and root organic matter (OM) to the soil carbon (C) stock is still unknown, mainly because of methodological restrictions. The novel measurement of the nonexchangeable hydrogen (H) ...

Cerium-based materials were intensively studied in last years because of their high oxygen storage capacity (OSC) associated to the reversible Ce4+ Ce3+ process and their properties closely related to the defect chemistr...

The standard method for spectrum analysis is the Discrete Fourier Transform(DFT), typically implemented using a Fast Fourier Transform (FFT) algorithm. However, certain applications require an on-line spectrum analysis o...

In this work TiO2 modified with nitrogen was synthesized by sol-gel method from the hydrolysis of titanium isopropoxide with urea solution in different concentrations so that the theoretical N/Ti molar ratio was equal to...

The first public product of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) is its Conceptual Framework. This conceptual and analytical tool, presented here in detail, will underpin all IPBE...

Chlorite dismutase (Cld) is a b-type hemecontaining enzymethat catalyzes the reduction of chlorite into chloride plus dioxygen. This enzyme has gained attention because it can be used in the development of bioremediation...
