The permeability characteristics of newborn pig skin and adult rat skin, either fresh or stored, to model drugs were examined and compared. Special attention was paid to the design to a new experimental system suitable for evaluation of skin permeability to various substances. Two types of model substances were used; insulin, a poorly absorbable substance with high molecular weight as a represe...

There are strong indications that oxidative phosphorylation processes are involved in the activation (or “priming, ” “sparking” (1)) of enzymatic fatty acid oxidation (l-5). Two major points of evidence exist: first, it is known that simultaneous oxidation of intermediates of the Krebs tricarboxylic acid cycle under conditions in which oxidative phosphorylation may be observed is required to ac...

When living cells of Nitella are exposed to an acetate buffer solution until the pH value of the sap is decreased and subsequently placed in a solution of brilliant cresyl blue, the rate of penetration of dye into the vacuole is found to decrease in the majority of cases, and increase in other cases, as compared with the control cells which are transferred to the dye solution directly from tap ...

Process optimization of BCB polymer to silicon oxide bonding was investigated. The suitable bonding temperature is about 300 C, while bond failure of BCB-to-oxide bonding is observed starting from 400 C. Bonding interface morphologies and bond strengths of BCB-to-oxide bonding were investigated as well. PECVD oxide to BCB bonding has better bonding quality than that of thermal oxide to BCB bond...

The Piedmont enjoys a highly regarded reputation for its historic sites and its world-class preservation practices. The well-preserved homes of presidents and extraordinary examples of architecture, known worldwide, dominate our landscape. We see daily the many ways in which preservation work enriches the lives of people who live in, work in, and visit our community. Numerous residents in the P...

Expelling of dyestuff into water resource system causes major thread to the environment. Adsorption is the cost effective and potential method to remove the dyes from the effluents. Therefore, an attempt was made to study the adsorption of dyestuff (Methylene Blue (MB), Bromophenol Blue (BPB) and Coomassie Brilliant Blue (CBB)) by α-chitin nanoparticles (CNP) prepared from Penaeus monodon (Fabr...

This paper reports a novel fabrication process to develop planarized isolated islands of benzocyclobutene (BCB) polymer embedded in a silicon substrate. Embedded BCB in silicon (EBiS) can be used as an alternative to silicon dioxide in fabrication of electrostatic micromotors, microgenerators, and other microelectromechanical devices. EBiS takes advantage of the low dielectric constant and ther...

This paper presents a new tuning mechanism for millimetre-wave BPF based on deflection of the BCB membrane of BCB packaging cap. A 3-pole parallel-coupled microstrip filter operating at 60 GHz is first implemented on 30 μm-thick BCB polymer substrate and then BCB-capped through our new anti-adhesion layer assisted wafer-level transfer technique. Gold electrodes are fabricated on top of the BCB ...
