Recently, government of India has hinted that public sector banks can be privatized. This led to unrest among the bank employees and they went on protest strike. In this paper it is tried to show that how few (20) private banks has been nationalized in 1980’s and same banks now government want to privatize. Motive of nationalization and motive behind privatization seems to be contradictory; same has been highlighted in this paper.

The consideration of sanctions imposed by NATO, the United States, the European Union, Britain and other states over Russia must be considered thoroughly, regardless of all the facts, evidence, factors, benefits of these sanctions for which countries.

The present research consists of proposing methodologies that aim to work on graph theory making use of problematic methods and heuristic principles of teaching-learning of Mathematics. It aims to develop a methodological proposal that contributes to the improvement of the teaching-learning process of Graph Theory and its applications in Higher Education, that is, in ISPCAB, based on the mental schemes presented by Biembengut and Hein. SPSS and R-Studio statistical software were used to extrapolate data obtained from the questionnaire applied to teachers and students and the pre-test and post-test that were applied to 55 students; An analytical approach was made to the theoretical foundations of the object of study, with an emphasis on teaching methods (which are the teacher's actions to organize teaching activities in order to promote student learning). This was followed by the characterization of the current state, where difficulties of various types were found, such as the lack of a clear, deep and objective introduction of the concepts related to the different types of graphs; difficulties in extracting the matrix, both adjacency and incidence, in a graph and difficulties in interpreting problems involving graph theory, by the way they are formulated. Then, we elaborate, present, indicate proposals and propose methodologies to be adopted to minimize, if not, overcome these difficulties through problematic teaching.

This study aims to identify the factors that underlie the difficulties in the teaching-learning process of Statistics Applied to Education at ISCED-Cabinda and at the Higher Pedagogical Social Sciences Arts and Humanities Institute of M’Banza Congo. For this purpose, in a population of 314 students and 6 teachers, a sample of 157 students and 6 teachers was chosen, from which they answered the questionnaires, whose opinions served for the diagnosis of the current situation of the teaching-learning process of this discipline, verifying the hypotheses and develop a conceptual model to mitigate the factors that make learning difficult. The research was quantitative-qualitative, where the questions of the questionnaires obeyed the Likert-type scale with statistical analyzes made with the help of the SPSS software, where it was found that the factors that make teaching-learning difficult in these institutions are: 1) the non-use of statistical softwares during teaching-learning process; 2) Negative results due to difficulties in calculating statistical measures of data grouped by classes, in classifying variables, in interpreting statistical measures and the behavior of data from graphs; and 3) the type of answers to the questions most valued by the teachers, which must coincide with the notes in the didactic material. The Mitigation Conceptual Model developed could serve to improve the current situation.

Paciente masculino de 69años con cuadro de abdomen agudo, debido ano contar con recursos de imagen apropiado (tomografía de abdomen, angiotomografía) se realiza laparotomía exploradora donde se identifica la presencia de porción de asas de intestino con zonas de necrosis. Se realiza resección e ileostomía. Reporte de patología confirma la presencia de trombosis venosa mesentérica segmentaria como causa de isquemia intestinal.

In this study, the photocatalytic performance of Tb, N co-doped titania nanocomposites was evaluated by degradation of methylene blue. The effects of calcination temperature and N doping amount on the catalytic activity were analyzed. In addition, the photocatalytic reaction kinetics of the nanocomposites was also discussed. The results showed that Tb-N-TiO2 exhibites the highest photocatalytic performance when the calcination temperature is 600 °C and the optimal doping amount of N is 6 %. Tb-N-TiO2, N-TiO2 and Tb-TiO2were fitted to the pseudo-first-order reaction kinetics, and the reaction rate constants were 0.03768 h-1, 0.56742 h-1 and 0.06289 h-1, respectively.
