This article introduced the work of ethylcellulose based polymeric microsphere loaded with nifedipine for reduction in frequency of administration with low solubility in aqueous medium and high rate of absorption in the stomach. The non-aqueous polymeric suspension was put dropwise into an aqueous medium containing polyvinyl alcohol as a surfactant for the synthesis of microsphere by solvent ev...

The cryo scanning electron microscopy (cryo-SEM) as well as high-pressure-freezing (HPF) belongs to cutting edge techniques in electron microscopy of hydrated samples [1]. However, their combination is not always easily applicable. Here, we present a way of combining high-pressure-freezing using EM PACT2 (Leica Microsystems) that fixes hydrated samples on a 1.4 mm sapphire discs and high resolu...

We present a new approach to fast certi cate revocation centered around the concept of an on-line semi-trusted mediator (SEM). The use of a SEM in conjunction with a simple threshold variant of the RSA cryptosystem (mediated RSA) o ers a number of practical advantages over current revocation techniques. Our approach simpli es validation of digital signatures and enables certi cate revocation wi...

Mild steel is used as main raw material in fabrication of equipment, chief material of construction and as weapons. During the storage and transportation conditions, it comes in contact with aggressive environment which leads to decrease in mechanical strength. Four different vapor phase corrosion inhibitors (VPCIs) i.e. n-Caprylic acid (CA), nButyric acid (BA), N,N-dimethyl propylene urea (DMP...

Transmission electron backscattered diffraction, t-EBSD, in the scanning electron microscope, SEM, was initially described in 2010 [1]. After slow initial acceptance, the number of publications in which it is used is increasing markedly. Many of the first applications took advantage of the higher resolution of t-EBSD in the study of thin films [2], [3]. More recently it is being used for pre-sc...

Electron backscattered diffraction (EBSD) has replaced electron channeling and selected area electron channeling patterns (SACPs) for many scanning electron microscopy (SEM) based crystallographic studies, due to the rapid collection rates and high spatial resolution of EBSD. Nevertheless, a number of SEM techniques, for example electron channeling contrast imaging (ECCI), are better served usi...

The authors have given us a lucid, concise, and accurate account of the TETRAD project, an account likely to clear much of the confusion over the philosophy of graph-based causal discovery methods. As one who has been active in the exploration and formulation of this philosophy, I am very pleased to see TETRAD arrive at this stage of development and now presented as a practical modeling tool fo...

Second-generation statistical techniques like Structural Equation Modeling (SEM) are being used more frequently by IS researchers to evaluate theoretical models. The purpose of this study is three-fold. First, we aim to ascertain whether there is a “fit” between IS researchers' choice of analytic method and theoretical models when they use second-generation techniques. Second, we seek to determ...

The scanning electron microscope (SEM) provides an ideal system for studying the three-dimensional surface structure of biological materials . Our previous work on the protozoan Opalina showed that instantaneous fixation, combined with critical point drying, faithfully preserved the pattern of ciliary coordination and the form of ciliary beat for scanning electron microscopy (1, 2) . I report h...

The 790-862 MHz frequency band is allocated for IMT-Advanced system on a co-primary basis operation alongside existing Digital Video BroadcastingTerrestrial (DVB-T), At WRC-07. As a result of frequency spectrum scarcity and emerging various wireless applications, coexistence and sharing between wireless systems become a recently considerable issue. Therefore, coexistence and sharing requirement...
