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...

Sir, At the turn of the nineteenth century, Ehrlich focused on the selective staining of malaria-infected cells over noninfected cells, with methylene blue and acridine orange. On reviewing this information, two simple questions arose: why do these compounds selectively target parasite infected cells and can this information be used against the parasite? We propose the following: methylene blue...

Methods are proposed for the estimation of the rate, activation energy, heat, and affinity of staining of histological sections, and approximate results are given for the staining of mucin, mast-cell granules, chromatin, cytoplasmic ribonucleic acid (RNA), cartilage matrix, and other structures by azure A. The half-staining time tj is the time taken by a substrate under given staining condition...

In the present study, preparation and electrochemical application of perfectly ordered arrays glassy carbon nanoelectrodes (GC-NEAs) is presented. After careful morphological characterization, we examined voltammetric behaviour on GC-NEAs some redox mediators commonly used in enzymatic biosensors. were fabricated by using nanoimprint lithography to generate nanoholes, with average radius 145 nm...

The dependence of nucleolar reformation on RNA synthesis that resumes in late anaphase or early telophase has been investigated in synchronously dividing Amoeba proteus. RNA synthesis was completely inhibited throughout all stages of mitosis and the early hours of interphase with high concentrations of actinomycin D. In such cells, nucleolus-like bodies that bind azure B and pyronin were appare...

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...
