BACKGROUND AND AIMS Only few data on the epicuticular waxes (EWs) of horsetails are available. This contribution therefore focuses on the wax micromorphology and chemical composition of Equisetum species of the subgenera Equisetum and Hippochaete. METHODOLOGY Distribution patterns and structural details of EW on the shoots were studied by scanning electron microscopy. After extraction with ch...

BACKGROUND In the treatment of human head lice infestation, healthcare providers are increasingly concerned about lice becoming resistant to existing pesticide treatments. Traditional pesticides, used to control these pests, have a neurological mechanism of action. This publication describes a topical solution with a non-traditional mechanism of action, based on physical disruption of the wax l...

STATEMENT OF PROBLEM Situations may arise in dental laboratories that could result in a time lapse between preparing the wax pattern of the removable partial denture framework and its casting into the cobalt-chromium alloy. PURPOSE This study investigated the effect of storage time of the wax pattern before casting and the influence of the palatal major connector design on the accuracy of its...

Objectives: The aim of the study was to evaluate marginal fit and fracture resistance after thermomechanical fatigue two types glass ceramic occlusal veneers constructed using techniques for wax pattern. Methods: Thirty-two non-carious maxillary molars were used in this study. Teeth prepared receive all veneers. Prepared teeth randomly divided into equal groups according fabrication material ve...

This paper describes the fabrication of microfluidic cloth-based analytical devices (μCADs) using a simple wax patterning method on cotton cloth for performing colorimetric bioassays. Commercial cotton cloth fabric is proposed as a new inexpensive, lightweight, and flexible platform for fabricating two- (2D) and three-dimensional (3D) microfluidic systems. We demonstrated that the wicking prope...

This study deals with the experimental measurements and numerical predictions of alloy shrinkage factors (SFs) related to the investment casting process. The dimensions of the A356 aluminum alloy casting were determined from the numerical simulation results of solidification, heat transfer, fluid dynamics, and deformation phenomena. The investment casting process was carried out using wax patte...

Pellets containing active ingredients were coated with water-insoluble powders, i.e. hydrogenated caster oil (Lubliwax (WAX)) and magnesium stearate (Mg-St). The influences of the structural difference of the sustained release layer and curing conditions on the drug release rate were investigated. Sodium valproate (VP-Na) was used as a highly water-soluble model drug. Drug release profiles were...
