: In terms of the theory of elementary pedogenetic processes, the pedogenetic process represents the totality of the integration processes of abiotic and biotic matter in the composition of the basic soil matter, which represents the first level of integration of matter in the soil, specific to it. Its further evolution is determined by the unidirectional action of humic substances resulting from the operation of the system "living organic matter ↔ dead organic matter". The driving force behind the continuous processes of structural-functional organization of the soil ecosystem are the processes of humus formation and those of accumulation-sequestration and stabilization of organic carbon in the structural aggregates responsible for the functioning of the soil ecosystem materialized in ecosistemic functions, including soil fertility. maintained All processes are performed in relatively balanced biogeochemical circuits of substances. Relative stability of the main diagnostic features. One-way realization of micro-, meso- and macroprocesses of expanded reproduction of soil fertility in closed circuits of substances.

: This study is a complex analysis of the processes of land degradation by erosion, gullying and landslides, which are a real problem that the territory of the Republic of Moldova faces. The scientific findings from research in the Tigheci Catchment (located northwest of the Tigheci Hills) argue for the region’s huge agricultural potential, but the land degradation processes lead to a reduction in the amount of humus and nutrients in the soil, thus limiting the productivity capacity. The erosion in the soil surface, the most widespread geomorphological process in a basin, has an appreciable intensity especially on the cuesta foreheads and the average rate of soil losses estimated, according to the Mo ț oc method, is 6.3 t/ha/year. Also, characteristic is the process of deep erosion, which is justified by the inventory of a number of 272 gullies, with a predominance of slope gullies that hold over 60% of the ravaged area. The landslides are the third category of geomorphological processes that contribute to land degradation. They cover an area of 4,365.26 ha and are in most cases stabilized. Often, the landslides are caused by the evolution of torrential organisms, which lead to the initiation and development of hollows. Therefore, the degraded land is a rather serious problem that requires practical implementations with real effects in the agricultural system.

: The management of the aggregation-structuring processes implies the intensification of the soil pedoplasm modeling processes under the direct and indirect action of the its biota. In the present research we started from the consideration of algal microflora as the nucleus of bacterial-algal cenosis responsible for the decomposition of various groups of organic substances (geno-metabolic networks). They decompose organic waste in consecutive series ensuring a closed circuit of substances and energy with development of the aggregate level of structural-functional organization of the soil organo-mineral biopedoplasm. It has been established that algalization of the typical moderately humiferous strongly overplowed chernozem through administration of algal biopreparations leads to the regeneration of the humification process and the improvement of the structural-aggregate condition of the soil. The mechanisms of this process are determined by the participation of algal biomass as a source of biological nitrogen for the humification process. Under algalization conditions, the aggregation processes proceed with the formation, mainly, of 5-1 and 3-0.5 mm aggregates and are determined by the agglutination processes with the participation of newly formed humic substances. The intensity of the aggregation-structuring processes differs depending on the species of administered cyanophyte algae and can be described with the following sequence in the sense of decreasing it: Nostoc gelatinosum > Combined lot > Cilindrospermum licheniforme > Calothrix gracilis > Nostoc linckia . The cyanophyte algae participate less in the direct aggregation processes of soil biopedoplasm. At the same time, the practiced technologies require crop rotations capable of contributing to increasing the degree of aggregate stability. In the pedofunctional aspect, the process of algalization of chernozems presupposes perspectives for sustaining the composition and diversity of the soil microbiome.

: The phenomenon of demographic ageing can be considered a social hazard which, depending on its size, can produce strong socio-economic imbalances in the region or state in which it occurs. This phenomenon takes place independently and cannot be easily stopped by legislative measures, as it is known that the restoration of structural imbalances in relation to age requires a long time. In Romania, the transformations that took place after 1989, in the political and economic system, in the social life, as well as in the mentality of the people, brought about important demographic changes. Therefore, the number of the population continuously decreased year by year, the demographic ageing along with the decrease of the birth rate and the increase of the number of emigrants being the main demographic phenomena that made their presence felt. These phenomena have manifested themselves mainly in rural areas. This paper aims to highlight the scale of the demographic ageing process in the rural areas of the North-East Region and to assess its socio-economic consequences in the medium and long term.

: Over time, the Danube has been a significant transportation hub, with a key role in developing a specific category of urban settlements: port cities. Several factors influenced the expansion of these cities, each with a different intensity and impact. Based on the historical context, port cities have experienced both times of evolution and periods of decline. This paper aims to analyze two port cities in Romania by highlighting the role of ports and related activities in the economic development of cities. The port cities of Galați and Brăila were chosen as case studies; in these cities, the role played by their ports as engines of development in the two cities was investigated. The analysis revealed that after 1990, the change of political regime and transition to an open market economy affected the economic situation in the two cities studied. Nowadays, ports have much smaller importance in the economies of both studied cities. This research is important as a starting point for understanding the current issues of the two cities and finding potential solutions.

: Urban forests, which means all trees, shrubs, lawns, and other vegetation from cities are very important spaces that are protected in order to protect and conserve biodiversity and the region’s structure. These forests have economic, social, and ecological functions. The research was realized in urban forests from Brasov city. The favorability of certain orographic and edaphic factors were determined for the selected species (by using these property values and sheets regarding the species ecological requirements (Norway spruce, silver fir, beech and sycamore). If we consider the ecological requirements of the main species that comprise the studied stands and a series of orographic (altitude) and edaphic factors (reaction, base saturation degree, edaphic volume, potential global trophicity), we were able to calculated the favorability of species based on grades. The conclusion was that Norway spruce has the highest favorability, followed by common beech. Even though silver fir has a lower favorability then Norway spruce, all plots have fir and Norway spruce in their composition. Furthermore, it can be observed that a higher favorability, as in the case of sycamore, does not necessarily determine its presence in more areas. On the contrary, sycamore appears only in a very low number of plots.

: There are limits recommended for environmental noise and occupational noise by the World Health Organization (WHO) and the International Standardization Organization (ISO). Therefore, noise levels were assessed in four different schools in Jalingo, the capital of Taraba State using a Lutron sound level meter, model SL – 4030. The aim of the study was to compare noise levels in the schools with the limits recommended by WHO and ISO, so as to make appropriate recommendations in case of undesirable results. The ANOVA statistical tool was used to demonstrate that the noise levels differ in the classrooms and the Least Significant Difference (LSD) statistics was used to show the significance of the variation of noise levels in the classrooms as suggested by the ANOVA. The mean equivalent noise levels (Leq (dB(A)) varied considerably above WHO recommended limits in classrooms. In the classrooms across all the schools, noise levels were within satisfactory range (61 – 75 dB(A)). This range however, exceeds the recommended noise limits in classrooms (35 – 55 dB(A)). Meanwhile, the control sample locations had mean noise level within the good range (41 – 60 dB(A)). It was also observed that at the control sites, mean noise levels were within the range recommended for classrooms during lessons. Higher noise levels than the endorsed limits by the WHO in the classrooms across all the schools are justifiable by so many factors such as: proximity to busy roads, students – Teacher’s activities and perhaps some acoustical reasons. Interestingly, the control of noise pollution in these schools to meet the international recommended standards is much possible if the recommendations from this study are obeyed.

: Brașov is the largest city in the Romanian Carpathians, being located inside the largest low-lying area in the country and exposed to western climatic influences, with well-defined local features, especially in the cold season, when many thermal extremes may occur. The main objective of this study was to analyze the minimum air temperatures and highlight their extreme values over the 1980-2015 period . The climatic data were collected from the Brașo v-Ghimbav meteorological station and a set of specific indices, generically called as indices of extremes and climate change by the WMO’s Expert Team on Climate Change Detection and Indices (ETCCDI), were subsequently calculated. The resulting quantitative assessments of minimum air-temperature variations in the above mentioned area has also proved that they can be useful tools in calculating other derived technical parameters which may be relevant for the design and onset of heating or cooling installations, in order to maintain a comfortable indoor climate in residential buildings.
