1b). However, to obtain high RI polymers, we have to include highly polarizable moieties without affecting the number density of the polymers. We select polyimides as a model polymer and create novel polyimides by incorporating highly polarizable functional groups into the polymer backbone. Polyimides have attracted much attention due their exceptional thermal stability…

Gastroretentive System of Metformin: Approaches to Effervescent Tablet Sudhanshu K Chakravati1, Javed Khan Pathan1, Sapna Malviya1, Anil Kharia1 Modern Institute of Pharmaceutical Sciences, Indore (MP) ABSTRACT Effervescent tablet generally contains in addition to active ingredients, mixture of acids/acid salts (Citric, Tartaric, Malic acid or any other suitable acid or acid anhydride) and carbonate and hydrogen carbonates (Sodium, Potassium or any other suitable alkali metal carbonate or…

and the interfacial transition zone (ITZ) [2]. Concrete is economical due to locally available aggregates that are used for concrete production. Physical aggregate properties that affect concrete properties include gradation, shape, texture, and density [1]. the mixing of fine and coarse aggregates, cement, water and the admixture is mixed to produced concrete. Aggregates are known to be particles of rock or equivalent come in all shapes, sizes, and strengths which when fetched together in an…

1.Soil forming factors 1) Climate- The climate of the Pullman series leans on the side of ustic and is in fact a Paleustoll, but can boarder on aridic at times. Ustic is an intermediate between udic and aridic with the winters being relatively dry, and the growing season is characterized by plant available moisture between significant periods of drought. The Pullman series meets this descriptions, in that it’s driest periods lie between July and August, and then December through February, with…

quality index consisting of appropriate indicators, forming a minimum data set, and scoring the indicators. The potential soil quality indicators were comprised of phosphate sorption capacity, cation exchange capacity, the content of organic matter, bulk density, water retention, random roughness, porosity, hydraulic conductivity, seal conductivity, saturated hydraulic conductivity, soil productivity, and rooting depth. Somewhat in contrast to Moebius-Clune et al. is Congreves et al. (2015), who…

Chapter:5 FUEL CELL MASS TRANSPORT Introduction Basic condition to produce or generate electricity from Fuel cell is that, it must have supplied the reactants and removed products to avoid any interruptions So, this process of supplying the reactants and removing the products is known as Fuel cell mass transport process. Mostly in this Chapter we are concerned with the movement of reactants and products within Fuel cell. Various fundamental equations that govern the transport of matter from…

2.3.1.2 Antioxidant analysis Two methods to measure the antioxidant activity are by determining its ability of hydrogen atom donation to a reactive species and/or check its ability to take off any molecules of oxidative initiation. Total antioxidant capacity (TAC) level evaluation can be classified into a direct method and indirect method. Indirect method or in vitro method consists of DPPH radical scavenging activity assay, Trolox equivalent antioxidant capacity (TEAC) and oxygen radical…

telescope, which prompted me to learn more about the topic and understand it on a deeper level. Outline Introduction In this stage, the topic will be introduced, as well as a brief introduction of the subtopics that will be addressed. However the bulk of this stage will be dedicated to discussing dark matter and its history in relation to galaxy clusters. Dark matter is a fairly new concept that has only been recently discovered by astronomers. Prior to the 1970’s, its existence was a mystery.…

The simple integral desorption model was used to represent the physical phenomena of the extraction process.20 The extraction vessel is loaded with leaf particles with an initial andrographolide concentration of S0 (g/g leaf particles) to form a packed bed system. Fresh supercritical solvent is fed in to the bed, the pore and void volumes () are initially free of solute, and the process is isothermal. The total mass balance in the supercritical fluid phase of this system can be described by the…
