“Integers and their representation” is the first section from the curriculum for 8th grade high school Informatics education in Bulgaria. The main topic in it is the study of binary numbers. The research shows that the current Bulgarian textbooks have excessive amount of mathematical problems and very few have direct practical applications. Further...
For decades SI prefixes have been used incorrectly in the IT world to define volumes of binary information. Kilo, mega, giga, etc. were widely accepted all over the world for powers of 2 instead of powers of 10. The introduction of new binary information prefixes kibi, mebi, gibi, etc. started in 1999. This change was proved difficult, because the...
“I have..., who has...?” is an educational game which is mainly popular in kindergartens with preschool children and in elementary schools. It is mostly practiced in English-speaking countries, especially in the USA. The article presents an adaptation of the game for the junior high school and high school with the subject „Information Technologies“...
The COVID-19 pandemic imposed a quick introduction of distance learning for many students. In Bulgaria, the Ministry of Education and Science obliged schools to work synchronously with their pupils using video conference rooms. After the easing of the containment measures, regular classroom education was restored. However, the problems with quarant...

В настоящия труд е положено усилие да се даде един по-широк поглед върху проблемите около изучаване на информатика в българските средни училища. Направено е предложение за преструктуриране на учебните програми така, че с минимално разместване на учебно съдържание между различни класове базовите знания по информатика да са по-достъпни. Направен е и...
Microbiologists often measure the diameter of inhibition zone of the antimicrobial activity over microorganisms by the disk-diffusion method of Bauer-Kirby. Usually, the measurement process is not accurate enough and it is often done visually with a ruler. More accurate measurements can be done when using photographs; however, when the photographs...
Когато се заговори за материална база за предметите информатика и инфор-
мационни технологии в училищата, обикновено реалността се свежда до кабинет
с работен компютър и достъп до интернет за всеки ученик, и средства за мулти-
медийна презентация за учителя – проектор и/или интерактивна дъска. Някои
теми от обучението по тези учебни предмети включв...
Книгата предлага колекция от теоретичните основи, необходими за доброто разбиране на съвремените системи за управление на нерелационни бази от данни (СУНРДБ) и практически сведения за най-популярните от тях. Авторите са подбрали много успешно нивото на детайли, в което да се навлезе за отделните системи, така че книгата постига обозрим обем, без да...
The article presents a website dedicated to problems with sophisms, which can be used as a didactical tool in help of teachers in Mathematics, Informatics and Informational Technologies. The project has started as a part of a diploma thesis in the Master‘s program “Technologies of Education in Mathematics and Informatics” in Sofia University “St. K...
The current research focuses on using computer software as a help for preparing, printing and evaluating paper-and-pencil tests. The practical realization includes a database design and a web-based frontend for
users of three different roles with upgrading permissions. The proposed software can be used as an effort to prevent the common cheating wh...

Представени са опити за справяне с проблема с механичното преписване при защита на доклади в сравнително нов и много динамичен откъм учебно съдържание учебен предмет в Техническия университет – София. Изследването е проведено в рамките на 7 последователни учебни години.
Some benefits from the scientific research of students and PhDs on informatics and informational technologies in the practice outside of the university: The paper presents the standard scientific research activities in the universities in Bulgaria and highlights the direct analogies with practical activities in the IT business.
In this paper we present an attempt to introduce some elements of parallel and network programming in the Object-Oriented Programming (OOP) subject with focus to increase the interdisciplinary relationships with the subjects Operating Systems and Parallel Programming. The additional tasks are introduced at the end of the course and are quite practi...
We present the two popular approaches in the teaching of SELECT statements in the introductory database course – the procedural approach and the set-based approach. Our study shows that the procedural approach comes very natural to the students and they tend to prefer it; however it leads them to a " dead end " on very complicated SELECT queries, e...
This study presents the results of five experiments which restructure the lab exams of a traditional Linear Algebra course by implementing interactive methods of education and software technologies. The student participants are encouraged to work cooperatively in class and to use a discussion forum for their homework. Each topic of the curriculum c...
The dissertation presents an organizational model for effective teaching of Linear Algebra. Interactive methods of education are presented in the seminar exams with a high emphasis on the practicaloriented problems and the interdisciplinary relationships with other subjects from the curriculum. The homework activities are leaded through Web 2.0 edu...
Въвеждането на математически формули в текст на компютър е стар проблем, добре познат от писането на учебници. Съществуват утвърдени софтуерни приложения към текстообработващи програми като LaTex и MathType, които са се наложили като стандарт в писането на математически текст. Същата проблематика естествено беше пренесена и в представянето на инфор...

Educational Dialogue Computer Programs (EDCP) were invented back in the 80s. These programs were led by a logical scheme called "Didactical Block Scheme". There have been university courses since 1990 in the Sofia University "St. Kliment Ohridski" and the Southwest University "Neofit Rilski" that provide ground for the development of EDCP applicati...
One generalized form of this problem is: " 3 vessels of volumes M, N and P contain respectively m, n and M-(m+n) liters liquid, where M=N+P, N >P, m M, n N and M-(m+n) P. Divide the liquid in two equal parts. " The solution is frequently done by trial-error. Perelman provided a " billiard " solution to the problem without prescriptions how to...

I understood that the congo red agar is used for detection of biofilms. I wonder if the method can be used also for detection of antibiofilm activity. Could this be a sensible solution:
1. I test a control group of pathogenic bacteria using congo red agar in order to prove that they are biofilm producers;
2. In experimental group I cover the same pathogenic bacteria with plant extract and I check the mix again with congo red agar in order to see if the biofilm still exists or not.
The chlorellin is the chemical compound which is first extracted from Chlorella vulgaris by Pratt in 1944. Spoehr in 1949 wrote that it is a mixture between fatty-acids and hyrdocarbons and its antimicrobial activity may be due to peroxide production; however I find no further sources on the actual chemical composition of that natural antibiotic. Can somebody help me further by pointing articles about the chemical composition of chlorellin?
