Opis:: We present results of Monte Carlo simulations of a model system of Co nanoparticles in an external magnetic field. In our simulations we take into account the interaction with the external magnetic field, the energy of crystallographic anisotropy and the dipole-dipole interactions between single domain nanoparticles. We apply the standard Metropolis algorithm to a cluster of 27 randomly distributed superparamagnetic Co nanoparticles. We investigate the dependence of blocking temperature $T_{B}$ on particle and cluster size.

Opis:: We use the Monte Carlo simulation method to investigate the influence of the signs of magnetocrystalline anisotropy constants and the magnetic dipole-dipole interactions on the zero field cooled-field cooled magnetization experiments and hysteresis curves of a system of magnetic nanoparticles. Positive first cubic anisotropy constant K₁ results in larger blocking temperatures and larger coercive fields of a system, while the second anisotropy constant K₂ is practically of negligible importance for the phenomena investigated. Magnetic dipole-dipole interactions are important only in the most dense systems of particles and their effects practically disappear for systems where the distance between the closest particles exceeds three particle diameters.

Opis:: More and more frequently companies decide to get rid of certain functions of their structures by using outside firms to provide components and services. Outsourcing, very popular in recent years, has the purpose of reducing spendings in departments of a company. However, it this goal achieved? Often, such cost reduction is connected with the dependence of the customer on the supplier - which can, in the long run, globally contribute to raising costs. Will such delegation of certain responsibilities not cause a significant danger of losing its independence and a gradual increase in spendings in such a way that, in a broader perspective, they will be much higher than the costs before outsourcing? What will happen when a company dependent on its supplier or provider wants to pass another or a different company a particular job? Furthermore, if the company management decided to dispense with the services offered by a third party - would we be able to import the data that we receive into any other system? The compilation is an attempt at familiarizing the reader with the meaning of Cloud computing, as well as the concepts directly related to it. An attempt has been made to systemise the knowledge of the subject and present the main premises and hazards that are associated with the implementation of solution.

Opis:: We investigate theoretically the electronic properties of graphene functionalized with nitrogen and boron atoms substituted into the graphene monolayer. Our study is based on the ab initio calculations in the framework of the density functional theory. We predict the dependence of the energy band gap, binding energy per atom, and the shift of the Fermi level on the concentration of dopants. Moreover, we examine the influence of the distribution of B/N atoms on the specified properties.
