Comparison of Industrial Dynamics of Food and Beverage Industry in Bulgaria, Romania and Greece

Industry dynamic is a key indicator for sustainable industry growth. It depends on variety of factors on international and regional level. One of the important driving forces on international level is seen in the face of economic and political alliances. Cultural and regional policies, and social behaviour are driving industry dynamics on a regional level though. Our hypothesis is that specific differences of industrial dynamics of the Balkan countries occurred based on economic and political alliances (EU membership; Euro zone, Black Sea Economic Cooperation). This hypothesis is verified with analysis of a traditional for the Balkans industrial sector like Food and Beverage. The paper aims to find out more evidence to verify a basic hypothesis. It includes a comparative analysis of some basic industrial dynamic’s indicators for the European Union (EU 16), Greece, Romania and Bulgaria. The analysed period is 2000-2010. The conclusions are concentrated mostly on Bulgaria.Food and Beverage Industry, Industrial dynamics, Industrial growth, Bulgaria, Greece, Romania, innovation practices in food and beverage, Agribusiness,

SOME WI-FI ACCESS POINTS IN THE CITY OF SOFIA

The purpose of this article is to present the results of a study of the number and type of Wi-Fi access points using applications for the collection, processing and analysis of data based on a sample collected in different areas and places with a significant concentration of people in a city Sofia, Bulgaria. Data on the number and type of access points were obtained by measurements taken at the respective locations. User equipment connects to different Wi-Fi access points located in different places in the city that are accessible. Data was collected for wireless access points that are fourth and fifth generation. Different generations in wireless networks have corresponding download and upload speeds and frequencies. In the article, the results are grouped and analyzed according to different characteristics.

Recent advances in electrochemical determination of anticancer drug 5-fluorouracil

Reliable, rapid, highly selective and sensitive analytical methods for the determination of antineoplastic agent 5-fluorouracil (5-FU) in human body fluids (blood serum/plasma and urine) are required to improve the chemotherapy regimen to reduce its toxicity and improve efficacy. Nowadays, electrochemical techniques provide a powerful analytical tool for 5-FU detection systems. This comprehensive review covers the advances in the development of electrochemical sensors for the quantitative determination of 5-FU, mainly focused on original studies reported from 2015 to date. We have summarized recent trends in the electrochemical sensor systems applied for the analysis of 5-FU in pharmaceutical formulations and biological samples, and critically evaluated the key performance metrics of these sensors (limit of detection, linear range, stability and recovery). Challenges and future outlooks in this field have also been discussed
