The samples were taken in lmereti region （west Georgia）. After extraction of samples, there were carried out spectral and HPLC analysis of compounds for the sake of qualitative and quantitative research of them. There are studied the flavonoid compounds of bee bread and pollen by using the HPLC methods, and naringin, rutin and quercetin are identified. Their amount counts about 20% of full content of flavonoids. The content of flavonols in bee bread and pollen has been established. It also has been determined that the amount of flavonoids during the storage period of products reduces to 6.17-5.03 g.kg-1.展开更多

In addition globalisation has presumably played a significant role in the productive restructuring of economies in which the service sector has had an increasing quantitative and qualitative importance over the years Therefore, an evaluation of the role of services in constructing regional competitive capacities is required. This paper aims at addressing indirectly the meaning of services on improving competitiveness by providing a wide-ranging analysis of regional efficiency of the Mexican service sector and its determinants as well as an overview of its territorial distribution and special isation patterns. We evaluate the patterns of concentration of the third sector and its branches, and specialisation of regions. The efficiency of the service sector in the NAFTA period is analysed further because of the impact of services on regional competitiveness. We employ state leve data to examine technical efficiency＇s differentials across regions and their determinants. The methodology includes data envelopment analysis to measure technical efficiency which is the dependent variable in a reduced form model that links regional performance with a number of proxies for various types of agglomeration economies such as specialisation, urbanisation and internal economies of scale展开更多
