Reproductive boll weevil populations are typically identified by the presence of a frass seal and protuberance at the oviposition site in cotton squares. However, despite the occurrence of other oviposition puncture seal types and their use in previous fecundity studies, the relationship of these respective puncture seal types and oviposition has not been clearly examined. In this study, newly ...

Solid deposition, such as the formation of ice on outdoor facilities, the deposition of scale in water reservoirs, the sedimentation of fat, oil, and grease (FOG) in sewer systems, and the precipitation of wax in petroleum pipelines, cause a serious waste of resources and irreversible environmental pollution. Inspired by fish and pitcher plants, we present a self-replenishable organogel materia...

It is generally assumed that all plant epidermis cells are covered with cuticles, and the distinct surface geometries of pavement cells, guard cells, and trichomes imply functional differences and possibly different wax compositions. However, experiments probing cell-type-specific wax compositions and biosynthesis have been lacking until recently. This review summarizes new evidence showing tha...

Drought stress activates several defense responses in plants, such as stomatal closure, maintenance of root water uptake, and synthesis of osmoprotectants. Accumulating evidence suggests that deposition of cuticular waxes is also associated with plant responses to cellular dehydration. Yet, how cuticular wax biosynthesis is regulated in response to drought is unknown. We have recently reported ...

The effect of active hand exercise and warm wax treatment was evaluated in 52 rheumatoid arthritis patients randomized into four groups: (1) both exercise and wax bath, (2) exercise only, (3) wax bath only, and (4) controls. Treatment was given three times a week for 4 weeks. Deficits in flexion and extension in digits II-V bilaterally, grip function, grip strength, pain, and stiffness were mea...

This paper reports a novel technique for fabricating three-dimensional (3D) microfluidic channels in a single sheet of paper, which greatly simplifies the fabrication process of 3D microfluidic paper-based analytical devices (3D-μPADs). This technique, derived from the popular wax printing technique for paper channel patterning, is capable of controlling the penetration depth of wax upon heatin...

Taking the axial heat conduction of wax deposition layer into account, a two-dimensional heat transfer model of calculating the temperature profile inside wax deposition layer was deduced and established based on the energy balance equation, the finite difference method was used to solve this model, and the influence of axial heat conduction on the distribution law of temperature profile inside...

Gao and Sonin (1994) have proposed a method for rapid prototyping and microfabrication by precise deposition and solidification of molten microdrops. Objects can be fabricated by a drop-on-demand, computer-controlled droplet generator. To understand the fundamentals of droplet deposition and solidification, experiments have been conducted using microcrystalline wax droplets (Schiaffino and Soni...

Wax esters are major constituents of the surface lipids in many terrestrial arthropods, but their study is complicated by their diversity. We developed a procedure for quantifying isomers in mixtures of straight-chain saturated and unsaturated wax esters having the same molecular weights, using single-ion monitoring of the total ion current data from gas chromatography-mass spectrometry. We exa...
