Here we describe methods for creating tissue-mimicking ultrasound phantoms based on patient anatomy using a soft material called gel wax. To recreate acoustically realistic tissue properties, two additives to gel wax were considered: paraffin wax to increase acoustic attenuation, and solid glass spheres to increase backscattering. The frequency dependence of ultrasound attenuation was well desc...

Hydrocarbon and wax ester components of cuticular lipids of the braconid parasitoid Habrobracon hebetor Say reared at 25 degrees C on larvae of a pyralid moth have been identified by GC-MS and analyzed with respect to adult age, mating status, and diet. The hydrocarbons range in carbon number from C(21) to C(45) and consist of a homologous series of n-alkanes, 11-, 13-, and 15-methyl alkanes, 1...

BACKGROUND Bone wax is traditionally used as part of surgical procedures to prevent bleeding from exposed spongy bone. It is an effective hemostatic device which creates a physical barrier. Unfortunately it interferes with subsequent bone healing and increases the risk of infection in experimental studies. Recently, a water-soluble, synthetic, hemostatic compound (Ostene®) was introduced to ser...

This article describes a procedure to generate functional path occlusion for ceramometal restorations. With this procedure, the metal framework is formed conventionally, full contour inlay wax is added to the metal framework, and the patient carves functional paths into the wax. These paths are registered with a stone matrix that the ceramist uses as a guide. Advantages over conventional techni...

This article describes the fabrication of a screw-retained, implant-supported wax pattern that enables the restorative dentist to predict the outcome of the final prosthesis. The wax pattern also affords the patient an opportunity to evaluate and approve the design of the planned prosthesis, thereby enhancing communication between the dentist and patient.

This article presents the development of an autonomous motion planning algorithm for a soft planar grasping manipulator capable of grasp-and-place operations by encapsulation with uncertainty in the position and shape of the object. The end effector of the soft manipulator is fabricated in one piece without weakening seams using lost-wax casting instead of the commonly used multilayer laminatio...

The physical treatment most frequently used for the hands in rheumatoid arthritis is the local paraffinwax bath. It was first described by Humphris (1919) and since then has been in general use. The standard textbooks of physical medicine and rheumatology refer to wax baths as being of value, but we have been unable to find any critical attempt to assess this. It is unusual for a patient with r...

Composite edible coatings were formulated with candelilla wax alone, and candelilla wax blended with beeswax, white mineral oil and oleic acid (2:1 ratios) as the lipid phase, and mesquite gum as the structural material and their corrected water vapor permeability (WVPc) were determined. The coatings were applied to Persian limes and their effect upon physiological weight loss, color and chemic...

Epicuticular waxes influence leaf reflectance, but the spatiotemporal dynamics in their reflectance properties have not been properly characterized, and its consequences remain unknown. In this study, we analysed the seasonal changes in wax reflectance of Scots pine needles. It tended to decrease with needle age and towards lower positions within the canopy. In addition, we also identified a cl...
