background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...

Theoretical research in the field of software development methodologies (SDM) shows that the use of SDM should improve the efficiency of the development team and the quality of the developed product, nevertheless in practice not many software development organizations use SDM. In our paper we present a research that provides a theoretical background for measuring the SDM suitability on two dime...

A method to elicit architecturally sensitive usability requirements: its integration into a software development process

The aim of this study is to investigate the application of polypyrrole/ polyaniline (PPy/PANI) nanofiberfor Cu (II) sorption from paper mill wastewater. The tests and their optimization results were basedon the experiments design in three levels of variables using Taguchi method. The results showed thatin Copper removal tests, the pH of the solution was the most effective para...

Agile software development has evolved into an increasingly mature software development approach and has been applied successfully in many software vendors’ development departments. In this position paper, we address the broader agile service development. Based on method engineering principles we define a framework that conceptualizes an operational way of working for the development of service...

The collocation of software development teams is common, especially in agile software development environments. However little is known about the impact of collocation on the team’s effectiveness. This paper explores the impact of collocating agile software development teams on a number of team effectiveness factors. The study focused on South African software development teams and gathered dat...

Little research has been conducted to date on the specific topic of the tailoring of systems development methods. Two related research areas—contingency factors research and method engineering—have exhibited a primarily deductive research focus. In contrast, this paper presents an inductive study into method tailoring in practice within the Motorola organisation. The findings illustrate the sop...
