The azure-winged magpie (Cyanopica cyanus), has long presented a puzzle for biologists. The naturalist Alfred Wallace was one of the first to consider it. The puzzle lies in its extraordinary distribution. It exists in two distinct locations: Iberia and eastern Asia, 9,000 kilometres apart. Two alternative theories have been put forward to explain this curious distribution. The first proposes t...

We discuss the use of cloud computing in technical (scientific) applications and identify characteristics such as loosely-coupled and data-intensive that lead to good performance. We give both general principles and several examples with an emphasis on use of the Azure cloud.

Current business faces new challenges that require modern and adjusted IT models. Authors of this paper try to identify and indicate selected challenges that are addressed by by cloud computing concept and Big Data solutions. Authors of this paper concentrate od Microsoft Azure cloud offering mainly in area of Big Data and they want to prove that development of Big Data solutions in cloud envir...

For example, a standard definition video of 100GB+ costs roughly $252 per year to store and transmit via a cloud service such as Windows Azure. The cost could run into hundreds of thousands of dollars when hours of videos or thousands of uncompressed images in terabytes are stored. The transmission cost and time of such uncompressed data is additional overhead, since it requires gigabytes of ba...

in this paper, the photochemical degradation of azure-b by cu2+/s2o82− process has beenpresented. cu2+ as photocatalyst and s2o82− ion as photooxidant used in this process. atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.the influence of various parameters on the performance of the treatment process has beenconsidered, such as ph, concentration o...

Exoprotease activity during 120 h of total energy and nutrient starvation was examined in two marine bacteria, Vibrio sp. strain S14 and Pseudomonas sp. strain S9. The activity was determined by spectrophotometric measurement of the rate of release of soluble color from an insoluble azure dye derivative of hide powder (hide powder azure). Starved cells of both strains (5 h for S14, and 4 or 24 ...
