Polymer rheological behavior in an Enhanced Oil Recovery (EOR) project is one of the critical factors to determine whether the polymer injection would be effective to increase the oil production in a field. Due to compli...

Objective. To evaluate the effectiveness of nested polymerase chain reaction (PCR) for diagnosis of extrapulmonary tuberculosis (ETB), as well as the impact of PCR results on clinical management. Materials and Methods. W...

Implants prepared with polymer blends [poly (e-caprolactone)-poly(lactide), PCL-PLA] at different rates were developed from microspheres. Approximately 19% of dexamethasone acetate was encapsulated into the microsphere...

In the present study, the influence of polymeric concentration, its blend and drug loading dose on the in vitro drug release pattern of alfuzosin hydrochloride from its transdermal patches has been investigated. Ratio ...

The aim of this study was to formulate ethyl cellulose (EC) microparticles for sustained release of nimesulide and study the effect of processing variables, drug to polymer ratio and also study the drug polymer compatibi...

The purpose of this study was to attain and characterize ternary complexes of simvastatin, β-cyclodextrin (βCD) and different polymers, and then select those that lead to a greater increase in drug solubility. The comp...

Polymeric and lipid nanocapsules suspensions of the natural compound curcumin were prepared in order to overcome limitations associated with its clinical applications, such as poor aqueous solubility and susceptibility t...

In the present investigation, extended release tablets of metoprolol succinate were developed using cellulose derivatives and natural gums as matrix formers and were evaluated for its extended release characteristics. Th...

"En esta tesis, se estudia el uso de iniciadores multifuncionales para la polimerización en masa de estireno. El objetivo general es desarrollar modelos matemáticos detallados, y a la vez genéricos, que permitan descr...

"Chemical Enhanced Oil Recovery by alkali, surfactant and/or polymer flooding could be o good option to produce remaining oil from brown fields. One parameter that affects performance and economics of a CEOR process is h...

Hydrophilic matrix tablets were developed with acyclovir (ACV), using hypromelose and polyethylene oxide (PEO) in different concentrations. Matrix tablets obtained in each formulation were evaluated to determine the weig...

Free films were obtained by the combination of a polymer EudragitTM FS30D and oligosaccharides (alpha or gamma-CDs), by a casting process. The films were characterized by DSC, TGA, FTIR and SEM. The influence of composit...

The goal of any drug delivery system is to provide a therapeutic amount of drug (s) to the proper site in the body in order to promptly achieve and there by to maintain the desired drug concentrations during treatment. T...

Benzocaine (BZC) is an ester-type local anesthetic used mainly in topical, dermal and mucosal formulations. The present work consists of the development and validation of analytical methodology for evaluation of benzocai...

The present study was undertaken to evaluate the effect of glyceryl monostearate (GMS) and stearic acid (SA) on the release profile of gliclazide from the matrix. Matrix tablets for the controlled delivery of gliclazide ...

In order to increase the flexibility of renewable energies and improve their integration into existing energy grids, efficient intermediate storage is necessary. High-purity hydrogen produced in a water electrolysis cell...
