The 17 International Conference on Flow Injection Analysis was held in Krakow, Poland, from 3 to 8 July, 2011. The conference was organized under the auspices of the Committee of Analytical Chemistry of the Polish Academy of Sciences and the Japanese Association for Flow Injection Analysis (JAFIA). This was the first time that Poland had hosted this conference, which has been held regularly sin...
The manual handling of solutions (known as “beaker chemistry”) remains the Achilles Heel of modern analytical instrumentation. It is currently being replaced by flow injection analysis (FIA), which is computer compatible and allows automated handling of sample and reagent solutions with a strict control of reaction conditions. The flow injection analysis (FIA) was preceded by the success of seg...
the study of interactions of jet into cross flow at different longitudinal and transverse angles ofjet was studied. the following components were designed and constructed: a low velocity windtunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jetinjection, and a spatial rake to measure the total pressure. the tests were carried out atlongitudinal (α...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
This work follows the general framework of polymer injection moulding simulation whose objectives are the mastering of the injection moulding process. The models of numerical simulation make it possible to predict the propagation of the molten polymer during the filling phase from the positioning of one point of injection or more. The objective of this paper is to propose a particular way to op...
The application of microelectrode arrays in electrochemical batch-injection analysis, injection volumes 100 ml, has been investigated using a random array of microdisks (RAM) electrode made with carbon ®bres. Preliminary batch-injection experiments involving hexacyanoferrate(II) oxidation, using ®xed-potential amperometry and cyclic voltammetry, showed the expected lesser dependence on injectio...
We numerically investigate the stability problem of the injection molding process. It was indicated by Bulters and Schepens Bulters and Schepens 2000 that surface defects of injection molded products may be attributed to a flow instability near the free surface during the filling stage of the mold. We examine the stability of this flow using the extended Pom–Pom constitutive equations. The mode...

The paper deals with the problem of testing computer system’s susceptibility to hardware faults by means of software implemented fault injectors. Basing on our experience with fault injection techniques we present various strategies of fault stressing in relevance to fault impact analysis in the function of the application input data profile, fault injection profile in time and space, resource ...
Some recent analytical sensors based on electrochemical and optical detection coupled with different flow techniques have been chosen in this overview. A brief description of fundamental concepts and applications of each flow technique, such as flow injection analysis (FIA), sequential injection analysis (SIA), all injection analysis (AIA), batch injection analysis (BIA), multicommutated FIA (M...
