1898. 25 години от обесването на Левски: юбилей и преса

Author(s): Elena Getova / Language(s): Bulgarian / Publication Year: 0

The year 1898 marked the first jubilee of Vasil Levski – 25 years since his hanging. The dynamics of political processes in liberated Bulgaria at the time present a rather interesting and particularly complex picture against the background of which this event unfolded. The stereotype of jubilee celebrations was yet to consolidate and this particular occasion – the anniversary since the death of the Apostle of freedom – makes visible the deep political contradictions inherited from previous historical realities. The manifestations of these contradictions can be seen in the press in 1898.

Author(s): Manoj Kumar,Anita Rani,Rajshree Khare,Hardeep Singh Tuli,Sunil Arora,Rajendra Kumar / Language(s): English / Issue: 1/2019

Novel hydrazone Schiff base viz. 6,6’,8,8’-tetramethyl-4,4’,7,7’- tetrahydro-7,7’-bi-1,2,4,5-tetrazocine-3,3’(2H,2’H)-dithionehas been synthesized from3,4-diacetylhexane-2,5-dione and thiocarbohydrazideandcharacterized. The bicyclichydrazone Schiff basehas been found active against bacteria[S.aureus and K.pneumoniaae] and fungi [A.niger and Trichophytonrubrum]. DNA photo-cleav¬age and antiangiogenic behavior of synthesized hydrazone Schiff base has been studied. Furthermore,the synthesizedhydrazone Schiff basesignificantly inhibited cell proliferation with IC50 value 62.5μg/ml. The flow-cytometry analysis of hy¬drazone Schiff base treated human breast cancer cells showed that apoptosis rate increased with increase in dose. In conclusion present study proposes the develop¬ment of novel therapeutic strategy for MCF-7 cancer cell treatment.

A Concept for Inclusive Physical Education Training Program for Future Pre-School and Primary-School Teachers

Author(s): Galena Terzieva / Language(s): English / Issue: 5/2019

The adoption of new normative documents in the field of education in Bulgaria determines the inclusion of children with special educational needs in general education schools. The significant and integral role which physical education plays in the educational process poses the question of the inclusion of children with impairments in motor activity training as well. Teachers implementing it contribute greatly to its positive effects. The main features of physical education include active motor activity and the related physical workload. In order for them to be adapted successfully to the specific needs of children with different disabilities, more specialized training is required. The analysis of the curricula of the faculties of education in Bulgaria shows that future pre-school and primary school teachers who will be responsible for the physical education of children in kindergartens and primary schools respectively do not receive appropriate training in adaptive physical education. The aim of this article is to present a concept for introducing a training programme on “Motor Activity Training and Inclusive Physical Education”, intended for students of the specialty Preschool and Primary School Education at the Faculty of Education, Trakia University, Bulgaria.

A New Approach for the Synthesis of P-Anisyl Ethyl Fumarate: a C-9154 Antibiotic Analogue

Author(s): Maulidan Firdaus,Ahmad Ainurofiq,Aulia Vellarani / Language(s): English / Issue: 6/2016

A simple, energy-efficient, and relatively quick synthetic procedure for the synthesis of p-anisyl ethyl fumarate from p-anisaldehyde has been carried out. The synthesis was started by solvent-free reduction of the aldehyde using sodium borohydrate. The second step was solvent-free condensation of the resulting alcohol with maleic anhydride to be followed by esterification of the resulting acid with ethanol in the presence of benzenesulfonic acid as the catalyst. Satisfactorily isolated yields (65-98%) were achieved confirming that the preparation of the C-9154 antibiotic analogue is possible in sustainable fashion.

A New Meaning of the Notion “Expansion of a Number”

Author(s): Rosen Nikolaev,Tanka Milkova,Radan Miryanov / Language(s): English / Issue: 6/2018

In the present paper a new meaning of the notion “expansion of a number” is proposed by the authors. Some interesting problems are considered with corresponding answers and summarized results. The idea is by means of only one digit (used several times) and different mathematical symbols, signs and operations, to express (to expand) other digits. The research could be used by students and teachers to generate new examples with educational purposes or to find alternative variants of the problems in the paper.

A Novel Approach for Kinetic Study of Alkaline Hydrolysis of Ethyl Acetate

Author(s): Mala Das Sharma,U.S.V.R. Hymavathi / Language(s): English / Issue: 5/2017

We present an innovative electromotive force (EMF) measurement technique to study the kinetic behavior during alkaline hydrolysis of ethyl acetate. The explicit feature of this research is the application of green chemistry ideas that are inherent in the experiment. Using the new approach, we find that the kinetic behavior of the reaction under study follows second order with an estimated rate constant value at 25°C to be 2.45 × 10-3 cm–3 min–1. This value is in excellent agreement with the conventional end-point neutralization titration method discussed previously in the literature. The novel EMF measurement technique is simple, fast, accurate and eco-friendly. Keeping in view of long-term sustainability of the ecosystem, we feel that there is an urgent need to switch over from conventional laboratory practices to green chemistry approaches. Further, the method discussed here may prove to be extremely useful for teachers, researchers and students who wish to carry out kinetic study of other systems.

A Smart Mobile Learning Conceptual Framework for Professional Development of UAE In-Service Teachers

Author(s): Athra Sultan Alawani Alawani,Abtar Darshan Singh / Language(s): English / Issue: 3/2017

Increasingly, mobile learning has been considered as a part of professional development due to its unique attributes: ubiquitous, flexible, highly personalized and easily accessible. It represents a paradigm shift for continuous professional development especially amongst teachers who have a tight working schedule. This paper will provide a conceptual framework for the design of a mobile learning course for UAE teachers’ professional development. It aims to assist teachers to continuously engage in professional development activities and mitigating challenges such as time constraints, suitability of training content, impactful strategies and personalization of learning. A smart conceptual framework based on the three important principles of learning design was developed and pilot tested. The main elements of the conceptual framework and the results of the pilot test are presented in this paper.

A továbbképzések hatása a pedagógusok szemléletére

Author(s): Ilona Liskó / Language(s): Hungarian / Issue: 4/2008

Ilona Liskó analyzed the data from a research project conducted between 2006–2007 which examined the effects of teacher trainings in the Integration Scheme. The Integration Scheme is intended to promote the integrated education of socially disadvantaged and Roma children and the improvement of the institutions that educate them. Throughout the research work the background of the trainees, the evaluation and the outcome of the trainings were examined. The study focuses on the impact of the trainings on the attitudes of the teachers trained. The data showed that the effectiveness of the trainings was strongly influenced by the attitudes of the trainees. The trainings had a positive effect on the attitudes of the teachers trained but the effect was rather small. The majority of the teachers did not believe that students’ skills could be improved neither before nor after the training, and they had serious doubts about whether a successful integration between schools would be possible at all.
