Chemistry course for radiochemistry engineers on the platform Moodle: a support to self-education for undergraduate students

The education challenges at present times include the incorporation of information and communication technologies (ICT) in the learning-teaching process. In Higher Education the agreement between the volume of information to be processed by the student, the available student’s time and the assimilation of the courses contents is very important. The new study plans in Cuban Universities include the reduction of the number of face to face hours and the increase of the available time for the student’s independent study. Then, it is necessary to develop abilities that upgrade learning capacity during a lifetime through the self-education. The first version of a course on chemistry for radiochemistry students using the platform Moodle and Open Educational Resources (OER) as a support to the undergraduate course is presented. The detailed topic plan of the course of chemistry for radiochemists, which was distributed week by week, and different activities combining communication, interactive and collaborative modules were implemented on the platform Moodle. The whole system was tested during the first semester of the 2010-2011 academic year. The course evaluation results were carried out through a survey among the students and discussion forums. The results showed a good acceptance by the students, a better efficiency in the teaching-learning process given by better planning of the individual study, a better preparation to perform the laboratory practices, the new possibilities of communication between students and teachers, the access to OER and greater self-conscious of the students on their own process of learning

Joint Channel and Carrier Estimation Using Extended Kalman Filter

In this paper a proposal of joint channel and carrier estimation using extended Kalman filter (EKF) is presented. For the proposed algorithm simulations are performed and the results are compared with the separate channel estimation based on the Kalman filter (KF) and carrier estimation based on the extended extended Kalman filter, EKF, joint channel and carrier estimation, synchronization, digital receiver. 

Dynamical Modelling and Simulation of Waste water Filtration Process by Submerged Membrane Bioreactors

A mathematical model was developed for the filtration process and the influence of aeration on Submerged Membrane Bioreactors. The dynamics of sludge attachment to and detachment from the membrane, in relation to the filtration and a strong intermittent aeration, were included in the model. The influence on the membrane fouling of intermittent aeration injected on the membrane surface, and its synchronization with intermittent filtration, were studied numerically and experimentally. For the evaluation of filtration cake development, the assumption of the presence of two cake layers (one dynamic and the other stable) was considered. The model development and simulation focused on the description of existing relationships among important system variables like mixed liquor suspended solids concentration, aeration, temperature of the sludge suspension, transmembrane pressure, and the fouling increase during the filtration process. The model obtained offers the possibility of improving the design configuration and operation strategies of Submerged Membrane Bioreactors in wastewater treatment, and it allows the of aeration-filtration cycles to be optimized

The premises and evaluation of new regulations aiming at limiting risk in the banking sector

This paper will aim at proving that the introduction of the reforms known as Basel III considerably eliminates the deficits of the Basel regulations from 2004, but will result in lower availability of loans for bank clients and will slow down the economic development. The article consists of three sections. The first part presents the role and challenges facing banks in times of crisis. In the second part special attention has been paid to the main assumptions of the changes proposed by the Basel Committee on Banking Supervision. The third chapter focuses on analyzing the predicted influence of Basel III on economy and banks operating in Poland and all over the world

Uregulowania nadzoru bankowego w nowej umowie kapitałowej (Basel II) i ocena ich konsekwencji dla polskiego sektora bankowego

The rapidly developing globalisation of world economies has caused that it has become necessary to establish international authorities to control public entities (including, but not limited to, banks). These are banks that operate in the international market in an especially active manner. To reduce any and all irregularities in the banking sector, the Basel Committee on Banking Supervision was established. As a result of further actions, the New Basel Capital Accord (Basel II), in details defining the methodology of capital adequacy measurement and target standards for the banking supervision, was published. The purpose of this document is to present major regulations of the New Capital Accord and assess their impact on the Polish banking sector. On the basis of a selected group of banks in Poland, we discuss the impact of new guidelines, for example, on a solvency ratio

Flow Induced by Dual-Turbine of Different Diameters in a Gas-Liquid Agitation System: the Agitation and Turbulence Indices

Flow induced by a dual turbine stirred tank was characterized measuring local velocities with a LDV and drawing the main velocity fields and the maps of turbulence intensities. The hydrodynamic regime studied in all the experiments was the so-called merging flow regime. Two impeller configurations were studied. In the first one, two disk style turbine of the same dimensions (configuration A) were used, while in the second one, the dimensions of the upper turbine were 20 % proportionally smaller than those of the lower turbine (configuration B). The agitation and turbulence indices were used to evaluate, as a first order approximation, the power consumption distribution between convective and turbulent flows. The comparison of the two-phase agitation systems studied showed that configuration B seems to be more efficient than configuration A, since both induce a similar global convective flow, but the first one assures a significant reduction of power consumption. The distribution of power consumption between convective and turbulent flows was evaluated using the agitation index and a new global parameter: turbulence ind
