Since the structured dimple surface is one of important functional drag-reducing surfaces, research on its efficient fabrication technology great significance for practical application this surface. Therefore, in order to grind surface, a topological mapping grinding method was proposed based kinematics principle and point set topology. Firstly, spaces workpiece wheel were established, features...

The aim of this study was to determine the effect total dissolved solids (TDS), extraction yield (EY), and grinding on polyphenols (TP), flavonoids (TF), antioxidant capacity (TAC) in a fermented specialty coffee prepared using different methods filtration (Hario V60, Aeropress, French press). concentrations compounds differed between TDS treatments preparation. TP TF with Hario V60 were highes...

We present a new method of tailoring the density of a sphere for use as a probe in high pressure-temperature physical property experiments on liquids. The method consists of a composite sphere made of an inner, high density, metallic, spherical core and an exterior, low density, refractory, spherical shell or mantle. Micromechanical techniques are used to fabricate the composite sphere. We desc...

Service-based systems should be able to dynamically seek replacements for faulty or underperforming services, thus performing self-healing. It may however be the case that available services do not match all requirements, leading the system to grind to a halt. In similar situations it would be better to choose alternative candidates which, while not fulfilling all the constraints, allow the sys...

This study to assessed the prevalence of signs and symptoms of temporomandibular disorders (TMD) by means of the frequency distribution of data for 218 dentistry students from a Brazilian public university using the Fonseca's questionnaire. The group consisted of 96 men and 122 women, with an average age of 20 years. Of the students, 53.21% showed some level of TMD: 35.78% mild TMD 11.93% moder...

Fine grinding mills have improved in design and efficiency in recent years, allowing major opportunities for treatment of materials where liberation to grind sizes below fifteen microns are required. The successful development of the IsaMill, a horizontal stirred mill, has produced equipment capable of grinding the larger tonnages which exist in mineral processing operations, to product sizes b...

This article presents a study of the staging and implementation of death and the death penalty in a number of popular MMOGs and relates it to players general experience of gameworlds. Game mechanics, writings and stories by designers and players, and the results of an online survey are analysed and discussed. The study shows that the death penalty is implemented much in the same way across worl...

This article explores the tension that lies in construction of resilience, which is at once, hopeful and inspiring yet also danger positioning individual as responsible for lack welfare support available. In articulating these contradictory readings, I treat The Handmaid’s Tale a ‘site where meaning feminism(s) produced contested’ (Ferreday Harris, 2017: 240) television text whose storytelling ...
