The present study was oriented towards microencapsulation of aspirin and the study of its release kinetics. The desired encapsulation was achieved by emulsion solvent evaporation method using ethyl cellulose (EC), cellulose acetate phthalate (CAP) and their mixture (1:1) of polymeric constituents. Characterization of the formulations was performed by size, shape, drug loading efficiency and in-...

Cognitive workload is a subjective term operantly defined as a worker’s perception of a work performance and work difficulty. To estimate workload through Electroencephalogram (EEG) requires good algorithm with best features. Objective of this research study was to estimate workload using linear classifiers on non linear data. Workload was presented by varying levels of Multi Attribute Task Bat...

The oral conventional metronidazole dosage forms have a short duration of action due to gastric emptying process, hence the treatment ulcus pepticum using become less effective. Due retaining form in stomach, preparation sustained released drug delivery systems has been developed. aim this study was developed alginate and chitosan as polymers that could last longer stomach. formulation consiste...

In this study, pH sensitive microsphere polymeric drug carriers were produced by using biodegradable natural gelatin and sodium alginate polymers. Microspheres loaded with prepared Ganoderma lucidum extract that is a medicinal mushroom has the potential to be used in several diseases’ treatment. Extract release kinetics of microspheres examined spectrophotometric method an UV spectrometer. Buff...

Abstract More than one teramole of carbon per year is subducted as carbonate or carbonaceous material. However, the influence carbonation/decarbonation reactions on seismic activity within subduction zones poorly understood. Here we present field and microstructural observations, including stable isotope analyses, veins Higuchi serpentinite body, Japan. We find that oxygen compositions indicate...

The present work deals with the comparison of in vitro dissolution profiles of fenofibrate liquisolid tablet formulations with those of marketed fenofibrate tablets, and the application of statistical methods to evaluate each method for its usefulness. The methods used to study dissolution profile comparison include Model independent method (Similarity factor, f2); Model dependent methods (Zero...

The aim of present work was to optimize the effect of Ethyl Cellulose (EC) and Polyvinyl Pyrrolidone (PVP) concentration in extended release solid dispersion of Glibenclamide using combination of hydrophilic and hydrophobic polymers such as Polyvinyl Pyrrolidone and Ethyl cellulose. The advantage of solid dispersion technique provides a unique approach to particle size reduction and increased r...

We study linearised massive gravity on the de Sitter background. With a smallenough graviton mass this may have had relevance to inflation, or the present-day cosmic acceleration. Higuchi has shown that this theory has a ghost as long as the dS curvature exceeds the graviton mass, 2H2 > m2; this would entail rapid instabilities. In this work we extend the model and observe that the helicity-0 m...
