Nanostructured radar absorbing materials (RAMs) have received steadily growing interest because of their fascinating properties and various applications compared with the bulk or micronized counterparts. These nanostructured materials have increased surface area, number of dangling bond atoms and unsaturated co -ordination on surface lead to interface polarization, multiple scatter and absorbin...

Abstract--A procedure is presented to determine the moisture diffusivity for drying from measured moisture concentratio~a profiles. From error analysis it is shown that the applied space grid for scanning and the one-dimensional resolution of the NMR (nuclear magnetic resonance) method used for the measurements had a minor influence on the accuracy of the determination of the moisture diffusivi...

BACKGROUND many elderly suffer from urinary incontinence and use absorbent pads. Pad use per day (PPD) is a frequently used measure of urinary incontinence. Nursing home residents are often dependent on help from nursing staff to change pads. This study was performed in order to determine whether PPD is a reliable method to quantify urinary incontinence in nursing home residents. Furthermore, t...

Birds utilize ultraviolet (UV) wavelengths for plumage signaling and sexual selection. Ultraviolet cues may also be used for the process of avian food selection. The aim of our study was to investigate whether a UV cue and a postingestive repellent can be used to condition food avoidance in red-winged blackbirds (Agelaius phoeniceus). We found that birds conditioned with an UV-absorbent, postin...

In this work, a finite element approach is presented for modelling sound propagation in perforated dissipative mufflers with non-homogeneous properties. The spatial variations of the acoustic properties can arise, for example, from uneven filling processes during manufacture and degradation associated with the flow of soot particles within the absorbent material. First, the finite element metho...

Over the past 50 years, absorbent hygiene products such as baby diapers and incontinence products have become essential features of modern day life. Through innovation and enhanced technology, their design, composition and performance have been dramatically upgraded from their early forms, and they have transformed the lives of millions of people, improving their quality of life. Skin health re...

The importance of moisture measurement in grain and seed is discussed, and a brief history of the development of moisture sensing instruments, based on sensing of dielectric properties of these materials, is presented. Data are presented graphically on the permittivities or dielectric properties of grain and seed showing their variation with frequency, moisture content, temperature, and bulk de...

In many children with enuresis repetitive awakening by an alarm as soon as urination begins will gradually train the brain to exert automatic control over the bladder. The child will eventually either wake up before urination or sleep throughout the night without needing to empty the bladder. Such treatment is accepted as the most successful way of curing bed-wetting and may result in over 80% ...
