the ultra-nanocrystalline diamond (uncd) was synthesized by the detonation of a high explosive mixture in water confinement. the presence of a diamond phase was revealed by x-ray diffraction (xrd) and transmission electron microscopy (tem). x-ray line broadening (xrlb) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. the micro st...

We present a pore-scale study of two-phase relative permeability in homogenous-wet porous media, and porous media altered to a mixed-wet state. A Shan-Chen type multicomponent lattice Boltzmann (LB) model is employed to determine pore-scale fluid distributions and relative permeability. Mixedwet states are created by altering the wettability of solid surfaces in contact with the nonwetting phas...

Health technology The study evaluated tympanomastoid surgery. A comparator was not explicitly stated at the outset, although it was likely to be no tympanomastoid surgery. The health technology was compared between two different patient groups. These were patients with wet ear suffering from chronic suppurative otitis media (CSOM) and patients with dry ear suffering from CSOM. The wet-ear group...

BACKGROUND Trichomoniasis is the most common sexually transmitted disease. However, limited data are available on an effective technique for the diagnosis of Trichomonas vaginalis. METHODS A cross-sectional study was conducted to evaluate the accuracy of wet mount microscopy, latex agglutination, Diamond's media, and polymerase chain reaction (PCR) for detection of T. vaginalis among symptoma...

Introduction: Chronic suppurative otitis media is a major public health problem in children and adults. Tympanoplasty is a surgical procedure which aims to prevent recurrent otorrhea and restore hearing ability. Objective: To compare the graft uptake and the hearing outcome of tympanoplasty in non cholesteatomatous chronic otitis media between wet and totally dry ears. Methods: A total of 108 w...

Several existing equations for solving the non-linear soil-hydraulic properties are introduced and validated to field and laboratory measured data. Models for non-linear hydraulic properties of unsaturated porous media arise from statistical and mathematical fit through the measured data and they can be expressed in forms of unsaturated permeability versus either pressure head or volumetric moi...

With the development in egocentric vision, skill measurement has been recently proposed as a novel topic in this emerging field. In this report, we record the the experimenter’s first-person videos in Wet labratories (wetlab), and measure his/her operative skills. Specifically, given the videos of expert and amateur, we analyze their head motions, hands motions, eye-hand coordinations and key-m...

The primary goal of this study is to compare wet versus dry sampling methods for three different media, (Whatman 41 filter papers, GhostWipes, and SKC Smear Tabs), These media were selected because they are the most commonly used means for the collection of beryllium from contaminated surfaces within the DOE Complex. A range of known concentrations of beryllium was introduced onto a smooth nonp...

Studies of the relation between capillary pressure (Pc) and fluid saturation (S) for porous media containing oi l -water or a i r -o i l -water , often assume that the medium is strongly water-wet. Natural porous media, however, are composed of a variety of mineral constituents; such media are typically composed of waterand oil-wet fractions. This study reports on twoand three-fluid Pc-S data f...
