Abstract:
Introduction. The article discusses the problem of assessing the similarity of the dissolution profiles of two batches of the nebivolol. The use of a generally accepted similarity factor for assessing equivalence is unacceptable in some cases, for example, for drugs with a high variability in the values of the release of the active substance from the formulation. At the same time, at present, there are no generally accepted approaches to comparing the profiles of the dissolution kinetics of drugs, with the exception of the method for assessing the comparability of profiles based on the mathema

Abstract:
In vitro dissolution testing is one of the most important tools for characterizing the performance of oral solid dosage forms. In order to demonstrate similarity between test and reference product, comparative dissolution profiles are performed. Selection of a suitable method for comparison of the dissolution profile of the reference product and the test product is of great importance especially in the case of biowaivers when similarity assessment is based on the in vitro data only. Various approaches have been developed for the comparison of dissolution profiles, however the usage of the f2 s

In recent years, drug release/dissolution from solid dosage forms has been the subject of intense and profitable scientific developments.

This study adopted the use of surface solid dispersions (SSDs) employing superdisintegrants, hydrophilic polymers and combined carriers including a superdisintegrant with a hydrophilic polymer.

Today, orally inhaled drugs found on the market suffer from variable and discontinuous pulmonary drug release which lowers efficacy and patience compliance.

It has always been a challenge to imitate the lung environment, therefore there is a constant development of standardized in vitro dissolution methods for inhaled products.

Abstract:
Abstract A study of the anodic dissolution of polycrystalline aluminum utilizing in-situ Atomic Force Microscopy (AFM) is reported. Using a novel snodic dissolution treatment, square terraced pyramids (or “ziggurats”) of constant width are formed on the surface. AFM contour and profile plots reveal the extremely square and flat surfaces of the plateaus on top of the ziggurats, all of them having nearly the same size. This treatment on an Al sample is also shown to yield a substantial improvement in its passivation and corrosion properties. The improved passivation obtained through this method

Abstract:
Abstract Crack initiation and propagation in sour environments have been studied as part of understanding sulfide stress cracking mechanism. This research evaluated crack growth rate of two heats of C110 under different loading modes and exposed to two different solutions with different buffer capacities (NACE Solution B and C). There was no effect of decreasing K profile on the crack growth rate behavior in either environment on either heat. The Kth estimated from DCB tests for heat I in solution C were consistent with the values measured using the constant K test method. However, in solution

Abstract:
Abstract Internal corrosion can occur in the natural gas transmission pipelines with the presence of aqueous electrolytes from the wet gas condensation or upstream plant upsets. Internal corrosion caused 15% of the incidents in natural gas transmission and gathering pipelines over the last 30 years. The ability to monitor internal corrosion online along the natural gas transmission pipelines before the structural integrity is compromised can have a significant impact on preventing catastrophic events as well as methane leaks resulting from corrosion. To develop a distributed optical fiber sens

Abstract:
Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was
