University of Huelva posted this:Possibility of identifying nautical headlights at the distance that reaches the light if the headlights.An instrument is proposed for the automatic identification of nautical lights in river or maritime navigation, also applicable on mainland. The invention must address a specific problem consisting of optimizing the adjustment of the optical system for the different incoming light intensities.
Cracow University of Technology posted this:The synthesis of silver nanoparticles suspension and nanosilver suspension in reductive system with urea for agrochemical and sanitary applications.The main advantage of proposed technology is the presence of urea in the system used commonly as a fertilizer promoting the growth of plants and both antifungal and antibacterial activity against pathogens. It also fits into the current trend towards the use of proecological technologies in industry. The resulting nanoparticles can be used in many industries, but the biggest potential lies in the agrochemical industry.
University of Vigo posted this:Procedure for sea urchin embryo cryopreservation and attached bioassayThis sea urchin (Paracentrotus lividus) embryo cryopreservation procedure with attached bioassay has been specifically designed for sea urchin blastula (8 hour development embryo) conservation in liquid nitrogen to be used as out of reproductive season biological supply. This protocol has applications in research, aquaculture and ecotoxicology. The process described is fully developed, from how to obtain blastula embryos from sea urchins, composition and concentration used of the cryoprotecting agent, cryopreservation procedure including the cryoprotecting agent addition and dilution methodology, the seeding temperature during freezing and including a post-thawing viability study The possibility of a sea urchin embryo biobank ensures not only the access to test organism embryos all year round but also access to these embryos in places where it was not possible before either for their distance to the ocean or for the lack of the necessary facilities to maintain reproductive adults in optimum conditions to breed. The development of the bioassay using cryopreserved sea urchin embryos will help overcome the seasonal constraints in application of bioassays to assess marine water quality.
Centre Technology Transfer CITTRU posted this:New pharmaceutical composition increasing fish immunityThe offer is an immunostimulatory preparation dedicated to fish based on herbal extract and vitamins. It is applied to fish by immersion (to water) which is a completely new method of administration for this type of preparation. This makes it free from limitations existing with respect to the food. The product could be used without withdrawal period in fish for human consumption, as well as in ornamental fish.
Universidad de Cádiz posted this:An improved fast and high throughput method for the sequential measurement of nitrate and nitrite in water samplesWe have developed an improved fast and sequential protocol that permits the determination of low concentrations of nitrite and nitrate in aquatic samples using small volumes. It is ideal to analyse large sets of samples with different characteristics, since it is enough a small amount of water the volume and cost of reagents and consumables are reduced.

RAMOT at Tel Aviv University Ltd. posted this:Enhancement of Durability, Sensitivity and Selectivity of Environmental Sensors & BioSensors by Peptide NanotubesA Peptide NanoForest, is a dense array of self assembling organic nanotubes, capable of enhancing sensitivity and selectivity parameters of amperometric electrode high-performance sensors. The patented Diphenylalanine (FF) aromatic dipeptide nanotubes are formed under mild conditions from inexpensive building blocks. These bioinspired materials have a unique mechanical strength. They have a high Young’s modulus of about 20–30 GPa. In addition, the inherent biocompatibility of the structures along with the options of their chemical and biological modifications, extraordinary thermal stability, and organic solvent stability, lead to a novel class of nanostructures for sensing applications. The vertical arrangement of the peptide nanotubes enable the deposition of a larger number of nanotubes on the same surface, resulting in a remarkable surface area increase. FF peptide-nanotube-based sensors are benchmarked to CNT-based sensor, and clearly demonstrate the enhancement effect. Project ID : 3-2011-149
RAMOT at Tel Aviv University Ltd. posted this:Characterization of Porous Media for Petroleum ExcavationsA diffusion magnetic resonance (MR) method for non-invasively visualizing geochemistry and microstructures of porous sediment samples. The method provides quantification of pore sizes, pore size distribution and measure on pore eccentricities even for heterogeneous samples in the presence of free water or other liquids. Most diffusion MR methods use single pulsed-field-gradient (PFG) MR sequences; however such sequences are only beneficial for measurement of uniform, highly ordered media. We use the angular bipolar double-pulsed-field gradient (bp-d-PFG) to measure the poly dispersed sizes and shapes of pores of sedimentary rock samples with inter connections and three-dimensional organization. No a priori knowledge on the sizes or distribution is required. Project ID : 6-2012-372
RAMOT at Tel Aviv University Ltd. posted this:Iron oxide nanoparticles (IOP) for the treatment of acute myocardial infarction (AMI) and other inflammatory conditionsA novel approach for the treatment of AMI has been developed using IOPs. IOPs, when injected into the infarcted myocardium, lead to improved heart function after MI. IOPs activate anti-inflammatory macrophages and thus promote tissue healing and repair and prevent myocardial remodeling and dysfunction. Potential Applications IOPs can be used to treat AMI and other inflammatory conditions associated with pro-inflammatory activated macrophages and to promote tissue healing and repair. Advantages ? IOPs are nontoxic ? IOPs are FDA approved for use in humans for MRI imaging Stage In vivo studies in mouse and rat models of MI and heart failure Project ID : 10-2011-247
