Zuverlässige numerische Berechnungen mit dem Spigot-Ansatz
Der Spigot-Ansatz ist eine elegante Vorgehensweise, spezielle numerische Werte zuverlässig, effizient und mit beliebiger Genauigkeit zu berechnen. Die Stärke des Ansatzes ist seine Effizienz, seine totale Korrektheit und seine mathematisch exakt begründete Sicherstellung einer gewünschten absoluten …

Fine coal beneficiation: comparison study of the separation efficiency of a dense medium cyclone and flat-bottom cyclone
… parameters included vortex finder diameter, spigot diameter, and solids concentration, each tested at three levels. For the dense medium cyclone, the parameters were vortex finder diameter, spigot diameter, and medium density, also varied at three levels. The central composite rotatable …

Determination of the main parameters affecting the performance of bridge falsework systems
… namely the bending behaviour and resistance of spigot joints and forkhead joints (falsework to formwork interface) from which no published research was found. Existing joint models are evaluated and improved alternative models are developed. The results of numerical studies of a selected …

Monitoring and evaluation of a ceramic water filter and hand-washing intervention in Northern Ghana
… to measure most flow rates through the spigot of the Kosim filter. PHW should choose one of three options obtain an objective measure of Kosim filter use: (1) adapt and develop a method to retrieve data from the Camelbak@ Flow MeterTM; (2) adopt the SWEETSenseTM monitoring and data …

Effects of installing point-of-use filters intended for lead removal on drinking water quality
… water samples were collected from a spigot where water enters the school and from sinks with and without POU filters. Lead, residual chlorine, particles (0.1-50 µm), bacteria, temperature, pH, and total organic carbon were measured. Lead concentrations in all unfiltered samples were …

Evaluating the technical performance and social acceptability of keg-shaped ceramic water filters in Northern Ghana
… minute for the first 3 liters, whereas the CPF's spigot averaged 1.42 liters per minute for the first three liters. Five households tried KWKs in their homes, and responses were positive, with households particularly liking that the KWK provided clean water, kept filtered water cool, and worked …

Factors controlling bacterial abundance, biomass and growth at the Bermuda Atlantic time-series site
… average of 26 % of estimated C settled below the spigot of a Niskin water sampler. Consequently, C measurements made on GF/F filters must account for the particles settling below the spigot of a water sampler as well as the number of bacteria lost during the process of filtration. This study is …

Investigation of Culvert Joints Employing Large Scale Tests and Numerical Simulations
… finite element analyses of a gasketed bell and spigot joint in a buried reinforced concrete pipeline subjected to surface loading have been developed employing material properties and joint rotational characteristics experimentally obtained. The data obtained from the experimental and …

Fluxes, dynamics and chemistry of particulates in the ocean
… for particles settling below the sampling spigot. The trap arrays were designed to sample the particulate fluxes both immediately above and within the nepheloid layer. The data derived from the traps have been used to estimate vertical fluxes of particles including, for the first time, an …

Assessing the effect of cone ratio, feed solids concentration and viscosity on hydrocyclone performance
… study focussed on the effect of the hydrocyclone spigot to vortex finder diameter ratio, termed as the cone ratio, solids concentration and viscosity on the classification of two dual density ores. The rheological characteristic of the overflow was also evaluated. A UG2 ore (Upper Group), which …

The Porcelain Groups
My background in clay has emphasized the development of technical considerations in functional ceramics as well as the search for personal images. The past two years have seen an emphasis on the exploration of technical areas chosen to lead to the development of a familiarity with techniques and a …
