Opis:
We consider on-line Ramsey numbers defined by a game played between two players, Builder and Painter. In each round Builder draws an the edge and Painter colors it either red or blue, as it appears. Builder’s goal is to force Painter to create a monochromatic copy of a fixed graph H in as few rounds as possible. The minimum number of rounds (assuming both players play perfectly) is the on-line Ramsey number (H) of the graph H. An asymmetric version of the on-line Ramsey numbers r(G,H) is defined accordingly. In 2005, Kurek and Ruciński computed r(C3). In this paper, we compute r(C4,Ck) for 3 ≤k ≤ 7. Most of the results are based on computer algorithms but we obtain the exact value r(C4) and do so without the help of computer algorithms.

Opis:
Liquid chromatography and electrophoresis techniques are very often applied in contemporary laboratory practice. These techniques usually show different separation selectivity. It is due to various separation mechanisms involved in these two modes. In the former, partition of solutes between stationary and mobile phases influences on separation selectivity and retention contrary to the latter in which electrophoretic effect is involved in separation mechanism. The features mentioned are very useful for combination of these two techniques into two-dimensional separation of complicated samples of biomedical and environmental origin. Development of such approach is a very promising for contemporary separation sciences. The paper presents an overview of two-dimensional separation techniques, in which both liquid chromatography and electrophoresis have been involved especially in continuous mode.

Opis:
Free flow electrophoresis, or carrier-free electrophoresis, is a technique based upon the principle of mobility of chargeable species in the electric field. However, unlike more widespread gel electrophoresis, free flow electrophoresis does not utilise any kind of solid support medium. Instead, species to be separated move within the space filled with aqueous buffer, which is constantly pumped in the direction perpendicular to the direction of the applied electric field. Such set-up allows for continuous separation, as compounds of the sample being processed form separate bands and leave the separation system through several different outlets located along the edge of the chamber. Furthermore, the use of mild separation conditions increases the chance of biologically active compounds retaining their activity after the separation is finished. These qualities make free flow electrophoresis an excellent tool for protein research and cytology. In this review, the basic theoretical aspects of the technique are outlined, with a special emphasis placed on various modes in which free flow electrophoresis can be operated. Besides, a review of milestone papers related to free flow electrophoresis technology is presented. Apart from the devices following the original concept of Barrollier and Hannig, an insight into the construction of recirculating instrumentation, multicompartment electrolysers as well as radially-symmetric chambers is provided. A special focus is placed on patents and commercialized solutions. Finally, the challenges of scaling-down free flow electrophoresis to micro-dimensions are introduced.

Opis:
High performance liquid chromatography (HPLC) is an instrumental analytical technique, which is widely used for a separation and determination of a mixture of components in many samples (e.g. of biomedical, pharmaceutical, food, and environmental origin). Despite several decades of the development of this technique, some aspects of the chromatographic process are still open to questions. This is particularly related to mechanisms of retention and selectivity of a separation. Improvement of the separation selectivity can be achieved by a change of the stationary phase type and qualitative and/or quantitative composition of the mobile phase. The replacement of the stationary phase does not ensure a smooth change of selectivity and retention, however, it generates additional costs of analysis. Therefore, the optimal conditions of chromatographic separation can be easily obtained by the change of a composition of the mobile phase, i.e. the type and/or concentration of its modifier (organic solvent). This paper presents an overview of approaches to explanation and interpretation of an influence of mobile phase composition on the retention and separation selectivity in liquid chromatography systems with particular emphasis on modifier type of eluent in the reversed phase high performance liquid chromatography (RP HPLC).

Opis:
This paper presents results of investigations on the application of CuO-water nanofluids for intensification of convective heat transfer. Performance of nanofluids with 2.2 and 4.0 vol.% CuO NPs (nanoparticles) content were examined with regard to heat transfer coefficient and pressure losses in case of turbulent flow in a tube. Negligible impact of examined nanofluid on heat transfer improvement was found. Moreover, measured pressure losses significantly exceeded those determined for primary base liquid. The observations showed that application of nanofluid for heat transfer intensification with a relatively high solid load in the examined flow range is rather controversial.

Opis:
An important element which completes all water management research is the practical implementation of the results and, if possible, further commercialisation, which is the subject of this paper. In practice, research results come in the form of specific copyright assets, protected under industrial property law or copyright law. In response to the need for solutions which would improve the process of commercializing research outcomes in water management is the Water Research to Market (WaterRtoM) project. The project is financed by the LIFE+ programme. The main goal of the project is to speed up the process of implementing research results in practice and to shorten the implementation period to 3-5 years by adding a step between research and the existing mechanisms for transferring technology.
