Studies on colloidal aggregation have brought forth theories on stability of colloidal gels and models for aggregation dynamics. Still, a complete link between developed frameworks and obtained laboratory observations has to be found. In this work, aggregates of silica nanoparticles (20 nm) are studied using diffusion limited cluster aggregation (DLCA) and reaction limited cluster aggregation (...
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Multidimensional database modelling with differentiated multiple aggregations. Many solutions have been defined for multidimensional database modelling. These propositions consider the same aggregation function to determine the values of an indicator accor...
The dimerization constants of Safranine T have been determined by studying the dependence of its absorption spectra on the temperature in the range 30–70 ◦C at different total concentrations of Safranine T (1.03×10−5, 1.44×10−5 and 1.73×10−5 M). The monomer–dimer equilibrium of Safranine T has been determined by applying MCR-ALS method on the absorpti...
in this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic ionic liquids (ils), 1 – allyl - 3 - methylimidazolium chloride ([amim]cl), 1 - ethyl - 3 - methylimidazolium chloride ([emim]cl), 1 - butyl - 3 - methylimidazolium chloride ([bmim]cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([bmim]bf4) were investigated using conductivity and laser light scatterin...
a series of indole-based aryl(aroyl)hydrazone analogs of antiplatelet indole-3-carboxaldehyde phenylhydrazone were synthesized by the schiff base formation reaction and their antiplatelet activity was assessed using human platelet rich plasma. the platelet concentrate was obtained using a two-step centrifugation protocol and adp, arachidonic acid and collagen were used as inducers of platelet a...
Crystal aggregation is one of the most crucial steps in kidney stone pathogenesis. However, previous studies of crystal aggregation were rarely done and quantitative analysis of aggregation degree was handicapped by a lack of the standard measurement. We thus performed an in vitro assay to generate aggregation of calcium oxalate monohydrate (COM) crystals with various concentrations (25-800 μg/...
Interval-valued intuitionistic fuzzy sets (IVIFSs), a generalization of fuzzy sets, is characterized by an interval-valued membership function, an interval-valued non-membership function.The objective of this paper is to deal with criteria aggregation problems using IVIFSs where there exists a prioritization relationship over the criteria.Based on the ${L}$ukasiewicz triangular norm, we first p...
DNA trafficking phenomena, such as information on where and to what extent DNA aggregation occurs, have yet to be fully characterised in the live cell. Here we characterise the aggregation of DNA when delivered through lipofection by applying the Number and Brightness (N&B) approach. The N&B analysis demonstrates extensive aggregation throughout the live cell with DNA clusters in the extremity ...
objective(s):alzheimer's disease (ad) is the most common age-related neurodegenerative disorder. one of the hallmarks of ad is an abnormal accumulation of fibril forms of tau protein which is known as a microtubule associated protein. in this regard, inhibition of tau aggregation has been documented to be a potent therapeutic approach in ad and tauopathies. unfortunately, the available syn...
to study the resistance to standard dosage of clopidogrel among iranian patients following percutaneous coronary intervention measured by platelet aggregation test.patients undergoing percutaneous coronary intervention in imam hussein medical center, tehran, iran, who were under treatment with aspirin, but had no history of clopidogrel usage, entered the study. patients received standard dosage...
