The concept of community resilience in rural areas comprises the idea of sustainability, ability to adapt or resist new conditions and external influences and to turn possible risks into opportunities. In order to reduce degradation of rural areas and to preserve rural environment and natural resources, rural communities need to be active in setting priorities, decision making and purposeful realization of initiatives. The LEADER program is an important instrument supporting local initiatives to strengthen communi...

Proper and accurate accounting of ecosystem accounts is increasingly central to our social and economic lives. Of particular importance are the information for water, air, forests, and soils. This information should be collected both territorially and in monetary terms. Therefore, the creation of accounts containing this information is necessary. This will allow for static and dynamic analysis of the collected information for a certain period of time. The purpose of this article is to cover the accounts on which t...

Two independent sources of information on intra-field heterogeneity of crop productivity were investigated. Field verification of both sources of information was carried out. The first source is a map of stable intra-field heterogeneity of soil fertility. This source is obtained by analyzing large satellite data for decades (1984 - 2020). The second source is a crop yield map for a particular year. The map was obtained according to the results of yield measurements from the sensors of the John Deere combine. A map...

Cyanobacteria are a diverse group of photosynthetic bacteria found in a wide variety of habitats where they play crucial roles. They are one of the most morphologically diverse groups. The evolutionary relationships and the classification are poorly understood. The whole genome sequencing added a new dimension to our understanding of genomes of cyanobacteria and the genome-based phylogeny came into existence. The aim of this study was to conduct a genomic comparison of phylogenetically closely related filamentous ...

Soil saprophytic nitrogen-fixing nodule bacteria (rhizobia) of the Sinorhizobium meliloti species are formed symbiosis with alfalfa and can also be a host of bacteriophages. Rhizobia have a symbiotic and saprophytic life phase?s cycle. Nodules formed by rhizobia on alfalfa roots are destroyed at the end of the growing season and bacteria surviving in nodule threads and did not transformed into bacteroids are released into the soil microbiome. The last is enriched in bacteriophages, which can significantly decrease...

Increased pollution of water resources leads to a deterioration of surface water and groundwater quality, and it initiates the application of various methods for water treatment. Adsorption on a suitable adsorption material is the most frequently used methods in water treatment. Adsorption processes are based on the adsorption of contaminants on the surface of an adsorption material. The molecules of the contaminant pass from the water environment to the solid adsorbent. Oxides, oxyhydroxides and hydroxide contain...

The heat transfer from the source of initiation to the adjacent surfaces is a physical phenomenon worth considering in the process of analyzing the fire. This complex phenomenon describes how the transport, exchange, and redistribution of the thermal energy are carried out and is based on the theoretical knowledge that describes the initiation and fire evolution in time. Flames transfer heat from nearby surfaces through two physical processes, convection, and radiation. A third mode of heat transfer is conduction,...

The matrix of silicon carbide (SiC) is sufficiently rigid and strong, but in order to fully realize its potential capabilities, it is necessary to reduce its fragility and increase its reliability when used under shock loading conditions, which is achieved by creating ceramic composites based on it. Zirconia (ZrO2) was chosen as a hardening additive, since it has very high resistance to crack propagation and thermal, electrical, optical, strength, and other properties. Stabilization of the cubic phase of zirconia ...

Correlation studies have been made between the gravitational field (Bouguer anomalies - G) and the magnetic field (common vector (T) and the vertical component dZ) for the territory of Bulgaria. The map data is in digital format, which makes it easier to calculate. The correlation itself is estimated from -1 to 0 and from 0 to +1, which means that a positive correlation is possible in the case of increased values of both parameters and vice versa - decreasing values are associated with reduced values. This forms a...

Environmental protection-related to economic activities have many important economic consequences. Normally, the threats to the environment come from economic development since all the problems concerning the protection of air, soil, and water always imply supplementary costs. All these costs must be well analyzed and balanced between the port administration, port companies, inhabitants, and authorities. In large ports areas from Romania, as Constanta and Mangalia near the Black Sea, during 1980-2010 were develope...
