After Poland's accession to the European Union economic units are obliged to obey the legal and strategic norms ruling on the common European market, including those aimed at preservation and ...introduction of high standards for the protection of natural environment. The consciousness on the necessity for introducing of changes related with production in protected areas is increasing among small and medium enterprises in Poland. They are characterised by high financial outputs turning into the barriers that make implementation of sustainable production pattern more difficult in the described sector of economy. The aim of the article is to indicate essential instruments of support for the companies of the small and medium enterprises sector based on the main areas of support application.
The paper presents a new approach to the economic activity of rural population in Poland in the past ten years. The aim of the paper is to present the analysis of tendencies of changes in the ...structure of the economic activity of rural population in Poland. The paper focuses on the main task – to consider the changes in the structure of rural population’s economic activity in respect to the changes in the numbers and the share of a particular category of individuals in the general rural population in a dynamic perspective, differentiating between the population involved and non-involved in farm activity. The main source of the research data was the results of Agricultural Index which was applied in Poland in 2011. The research also used the materials from the Main Statistical Office and authors’ previous studies. The main conclusions suggest that during the 10-year period since Poland’s accession to the European Union some noticeable changes occurred in the economic activity of rural population. Demographic, educational, and social factors have played an important role. Extended education period has resulted in later entry of the youngest working age population into the labour market, which has both positive and negative consequences. It is necessary to bear in mind that activity is not a constant value assigned to a given professional or social group. Furthermore, the measurement of economic activity cannot be identical for each work station, function fulfilled or social role adopted.

Spaceborne active sensors have been used for several years to study the Earth's surface and atmosphere. The intent of this paper is to present the unique types of sensors and their characteristics ...that determine their individual frequency needs; to present performance and interference criteria necessary for compatibility studies with other services in the frequency bands of interest; and to present a status of current frequency spectrum use and needs and compatibility studies of spaceborne active sensors and other services, along with any issues or concerns.
This report describes a study of the effectiveness of beach nourishment along the cohesive shore of St. Joseph Harbor on Lake Michigan. Objectives of the study were as follows: To improve ...understanding of the sediment transport processes for both fine-grain and coarse-grain sand components at this site. To improve understanding of the relationship between movement of the cohesionless sediment (both fine and coarse-grain components) and the irreversible downcutting of the underlying glacial till (cohesive sediment) at this site. To apply the improved understanding of the sediment transport and erosion processes in developing recommendations for beach nourishment at the St. Joseph site. To formulate general principles for beach nourishment of cohesive shore sites that suffer from a sediment supply deficit due to the presence of an uplift littoral barrier. Data in the form of repeated beach profiles, lake bed bathymetry, and shoreline recession rates are summarized. The results of a series of analyses performed to develop an understanding of the evolution of the shoreline and lake bed in the vicinity of St Joseph, and the influence of the beach nourishment program on this evolution, are presented. A descriptive model of the historic coastal morphodynamics in the vicinity of St. Joseph is developed and presented, and this descriptive model is used to project the future evolution of coastal morphology. recommendations for future nourishment efforts at St Joseph are made on the basis of establishing realistic goals for the program
