This paper presents a strategy, based on requirement patterns (RP), aimed at improving the requirement analysis discipline by allowing business analysts (BA) to produce more reliable SW requirements in a significantly shorter time, minimising the overall requirement risks. In numerous business organisations, IT systems are increasing their strategic significance. In extremely competitive enviro...

I rst celebrate the immense success of twentieth century physics, but then urge that the future may bring many surprises, even in the basic structures of physical

Transcriptional network evolution is central to the development of complex biological systems. Networks can evolve through variation of master regulators and/or by changes in regulation of genes within networks. To gain insight into meaningful evolutionary differences in large networks, it is essential to address the functional consequences of sequence differences in response elements (REs) tar...

The paper proposes modeling calcein release kinetics (considered hydrophilic drug model) from interpenetrating network matrix of hydrogel type, based on combinations of two polymers, of which the chitosan is common. The release process is analyzed for different increasing time intervals, divided upon release kinetics evolution. For each time interval, a dominant release mechanism was identified...

In the modern era of neurosurgery, the use of the operative microscope, rigid rod-lens endoscope, and neuronavigation has helped to overcome some of the previous limitations of surgery due to poor lighting and anatomic localization available to the surgeon. Over the last thirty years, the supraorbital craniotomy and subfrontal approach through an eyebrow incision have been developed and refined...

Coal structure and its evolution in catalytic hydrogenation are studied in this work. The hydrogenation experiments were performed in tubing bomb reactors, in the absence of solvent, with an initial pressure of 10 MPa of H2, and for a reaction time of 30 min; iron sulfide was the catalyst precursor. The characterization of the solid residues was performed by different techniques, especially sol...

the modern infirmary is the evolutional product of the dialectic interface between medical theories at each time and the outcome of their application in clinical practice. the infirmary as we know it today did not exist during antiquity, but the different precursors of the modern hospital emerged as a result of the interaction between medical theory and practice. during antiquity the hippocrati...

The meiotic chromosomes of 10 species (Pohlia elongata, Anomobryum cymbifolium, Brachymenium acuminatum, B. ochianum, B. sikkimense, Bryum cellulare, B. pseudotriquetrum, B. apiculatum, B. capillare and B. atrovirense), in four genera of the family Bryaceae of acrocarpous mosses are studied with special emphasis on their evolution, polyploidy and cytological features with reference to interrela...

different discrete models of population dynamics of certain insects have been investigated under various feasible conditions within the framework of nonlinear dynamics. evolutionary phenomena are discussed through bifurcation analysis leading to chaos. some tools of nonlinear dynamics, such as lyapunov characteristic exponents (lce), lyapunov numbers, correlation dimension, etc. are calculated ...
