The surface water microlayer (SML) is a thin layer found at the interface of the hydrosphere and the atmosphere. It is capable of accumulating chemical substances and microorganisms at a rate as high as 100-fold greater than that observed in the subsurface water. The rate of accumulation of biogens and chlorophyll a in SML of an estuary, where marine and fresh waters mix, varies considerably and it...
An increasing awareness of consumers is reflected in a growing demand for products which are manufactured in a particular way, with unique ingredients, or which are of a particular origin. The analysis of consumers’ preferences makes it possible to define factors which determine the purchase of regional products. The aim of the work was to identify factors which determine the purchase of regional...
Background. The links between dietary patterns, the perception of one’s body weight and diet as well preparing meals are poorly recognised in the literature. In order to develop effective nutritional education and focused interventions, more of such information is thereby required to improve the nation’s health. Objective. To identify dietary patterns based on declared food consumption rates and subject...
The aim of the paper was to present the economic situation of farms in the countries of the EU at two different moments in time, and to attempt to assess changes in their situations in the considered period. Analyses were carried out on the basis of FADN data. The object of the study was the economic situation, including production potential, production and economic results and financial indicators...
In this study, the correlation coefficients among agro-morphological variation, genetic diversity, and drought tolerance in 44 rice cultivars were analyzed. The drought tolerance at seeding stage (DTS) was significantly proportional to drought tolerance at vegetative stage (DTV) (r = 0.60). In addition, DTS and DTV had strong significant positive correlation to leaf roll (r = 0.87 and 0.54, respectively)...
One of characteristic feature of contemporary data bases is their growing dynamics. The number of registered entities as well as their group structure tends to dynamically grow. In order to effectively determine the rapidly changing number and structure of clusters, appropriate methods of cluster analysis have to be applied. The paper presents the results of simulation research concerning the possibility...
