Bricks manufactured from dried sludge collected from an industrial wastewater treatment plant were investigated. Results of tests indicated that the sludge proportion and the firing temperature were the two key factors determining the brick quality. Increasing the sludge content results in a decrease of brick shrinkage, water absorption, and compressive strength. Results also showed that the br...

The main objective of the present study was to develop matrix-moderated transdermal systems of Diltiazem HCl using various proportions of Ficus reticuleta fruit mucilage. Physical evaluation was performed such as moisture content, moisture uptake, tensile strength, flatness and folding endurance. In-vitro penetration studies were performed in a Keshary-Chien diffusion cell. The matrix-type tran...

Transdermal patches were developed for a low oral bioavailable drug, lacidipine (LCDP) employing ethyl cellulose/Eudragit RL100 and polyvinyl pyrollidone (PVP) as polymeric matrices. The effect of binary mixtures of polymers on physicochemical properties such as thickness, moisture absorption and moisture content; in vitro release, ex vivo permeation and mechanical properties was evaluated. Ex ...

Article history: Received on: 15/12/2012 Revised on: 24/02/2013 Accepted on: 11/03/2013 Available online: 30/03/2013 Verapamil Hydrochloride is a calcium channel blocking anti-anginal agent. Extensive first pass metabolism, low bioavailability (~20%) and short biological half life (4.8 hrs) altogether makes it an ideal candidate for transdermal drug delivery. The objectives of this study were t...

The thermo-mechanical testing of HYSOL FP4549 polymer-filled underfill materials was conducted under different strain rate and temperature environment. A new specimen preparation procedure and further test methodology are developed to characterize the time–temperature mechanical behaviors of underfill materials. The stress–strain behavior of materials is simulated with constitutive framework, a...

drying behavior of two types of pomegranates as well as the effect of drying conditions on moisture loss trend and on effective diffusion coefficient of arils are discussed in this article. also, an appropriate mathematical drying model as well as the activation energy of sweet and sour pomegranate arils, dried in vacuum and microwave driers are pursued and presented. results of regression anal...

Fibre metal laminates (FMLs) have appeared as the most suitable materials for shipbuilding, aeronautical and aerospace applications due to their superior mechanical properties over traditional materials. In this paper, degradation in flexural and impact properties of glass fibre/epoxy composite (GF/E composite) and stainless steel glass fibre/epoxy fibre metal laminate (SS FML) due to hygrother...
