This research is conducted with a view to investigate performance of concrete containing high volumes of ASTM Class C fly ash. A portland cement concrete, proportioned to have 28-day compressive strength of 6,000 psi (41 N4Pa) is used in this study. Concrete mixes are also proportioned to have various levels of cement replacement by fly ash ranging from 40% to 70% by weight. Concrete performanc...

Introduction: MR-compatible implants and instruments for interventions under MR-imaging can cause susceptibility artifacts [1, 2]. Before clinical diagnostics or intervention, it must be known in what extent those artifacts could overlay the tissue of interest. For that reason, ASTM developed the standard F2119 [2] which describes how to determine the artifact’ size of passive implants. The sta...

The detailed characterisation of middle distillates is essential for a better understanding of reactions involved in refining process. Owing to higher resolution power and enhanced sensitivity, comprehensive two-dimensional gas chromatography (GC x GC) is a powerful tool for improving characterisation of petroleum samples. The aim of this paper is to compare GC x GC and various ASTM methods -- ...

In this study, static load bearing strength of pin-connected carbon fiber-reinforced polyphenylenesulphide (PPS) composites that have [(08/908)]3s stacking sequence was investigated. Firstly, the samples were loaded dynamically, and then the same samples were loaded statically. The results obtained from this sequential experiment were compared with the results obtained from samples that were lo...

The aim of this work is to investigate how ANFIS modelling of the chloride permeability of concrete can contribute to the sustainable development. Therefore, to have an opinion about service lives of concrete structures, especially the reinforced ones. Thus, some mixture properties and the rapid chloride permeability test results of different types of concretes obtained from a previous study ar...

The range of the Anton Hipp GmbH systems consists of different system components, which all comprehend indications for skeletal osteosynthesis. Every implant system distinguishes, based on the diameter of the individual titan screws, through the description and an individual color code attached on every implant system. Anton Hipp implants are manufactured of commercial clean titan according to ...

In order to avoid or predict cavitation erosion, it is necessary to know resistance of materials against to cavitation impacts. The cavitation impacts, which are larger than certain threshold level, only affect cavitation erosion of materials. In the present paper, existence of the threshold level was revealed experimentally. The threshold level of material is a new parameter to predict the cav...
