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.

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.

90 години Старозагорска опера и 70 години от одържавяването й

Author(s): Emiliya Zhunich / Language(s): Bulgarian / Issue: 2/2016

90 years ago a group of enthusiasts form an opera ensemble, as it occurs in many other localities. And if after one or two titles everything finishes mainly because of lack of funding, exactly in that consists the heroism of citizens of Stara Zagora: the only amateur ensemble which exists 21 years long, and after that it is nationalized in 1946. The nationalization is a kind of recognition but this leads to shocks. In 1967 lays the beginnings of the annually organized Festival of the Opera and Ballet Arts – a mirror of the achievements in the area of music and performing arts. Because of a conflagration end of 1991 the ensemble left homeless. In 2015 the State Operа Stara Zagora celebrates its 90th anniversary, and on the 1st of April 2016 it is 70 years since its nationalization.

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 Continuum of Approaches to School Inspections: Cases from Europe

Author(s): Rossitsa Simeonova,Yonka Parvanova,Martin Brown,Gerry McNamara,Sarah Gardezi,Joe O’Hara,Laura Del Castillo Blanco,Zacharoula Kechri,Eleni Beniata / Language(s): English / Issue: 4/2020

School inspection systems have undergone a transformation in response to the changing social and economic scenarios across Europe. However, two major approaches can easily be identified that also define the two ends of the continuum of the approaches to school inspection. On one end is a high stake sanctions oriented inspection while on the other end is the low stakes advisory inspection. The elements that contribute to the rigour of school inspection include governance arrangements, statutory powers of the inspectorate including powers of sanction, the forms and frequency of inspection visits, the level of emphasis on school self-evaluation and action planning for improvement; and availability of support services for the schools. The current paper presents four cases from Europe: Bulgaria, Ireland, Greece and Spain (Extremadura) describing how school inspection is organised in these countries as defined in the governing legislation and to which end of the continuum their inspection system is tilted in the light of that case’s performance on the above indicators. Towards the end, this paper makes a comparison of the cases and suggests why the relationship of trust and respect between inspectors and the inspected is stronger in some cases and how developing inspection systems can benefit from analysing the established systems.

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.

Four rules of thumb were developed to find the absolute configuration of a molecule without using any stereo model or hand analogies. This method will be a boon for students who are unable to visualize a three-dimensional structure or any model. A maximum thirty seconds is required to assign absolute configuration by using this method.

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.
