Published: February 2023

The present article is the literature reviews of transformational leadership style and its efficacy within the health organization specially the nurses’ job performance. Nurses are the frontline defenders in health care settings. Therefore, their leadership style has great importance in the performance. Nursing leaders have the positive impact on the efficiency of the nursing team members’ work performance. Furthermore, the literature review probes the concept of transformational role which is the most important part of job satisfaction and job performance. The relationship of transformation style and job performance was rather debatable in different research studies. Hence, it is the priority to comprehend the concept of transformational leadership and evaluate its impact on nurses’ job performance. Therefore, the transformational leadership style would resolve different health setting problems. It improves nurses’ performance resulting minimize patients’ hospital stay. Therefore, a high outcome could be managed with fewer resources. A very few studies were conducted on a transformational leadership style among front line shoulders i.e. nurses.

Published: February 2023

Although the notion of the metaverse is implicit in some popular video games, its concept is currently being rethought, in addition to adapting it to various activities that have progressively migrated to the digital world, such as work, commerce, education and recreation. It is projected for the coming years a high financial investment in research, development and implementation of technology, whose main feature is virtual reality. According to the technological conglomerate that drives its progress, the main objective is to make digital connections an immersive experience that enhances human relationships. Now, historically, the tech giants are not driven by altruistic purposes but by mass control in addition to their economic benefits, over and above that which is obvious, the question remains as to whether it is a really necessary technology. At first glance, it may offer advantages in the field of education and labor action. However, the technology has some sharp edges that must be treated with great care. In that sense, this essay, in addition to exposing the technology, offers ideas for debate about its desirability and social impact.

The program that displays the user's desired print color is called color recognition technology. It compares the color codes that the program already provides with the image whose colors we want to know. Let's begin by asking, We are aware of a disability that is very common in humans called "color blindness." Though it is very common in humans, most people can live with it because, as long as you don't think too much about the colors, it won't affect your overall performance. The future is self- driving vehicles that require color recognition to make road travel simple. It is true that no one has seen the future, that currently there is no cure for color blindness. How ever is always small). The program compares the R, G, and B values of colors to those in the image. After that, the name of the color is shown to the user in a way that is easy for them to see. This system can help normal people, especially men, understand colors, so it could be very useful. It could also be used to connect this system to goggles or specs and helmets for motorcycle drivers. These things may not seem like they would be of any use right now to most people, but those who suffer from it probably find Because it will help them recognize the color (even if they won't see it, they'll still be able to recognize it). Therefore, it is straightforward to assert that the implementation of this program will benefit a large number of individuals. Asa result, the program is designed with very low sensitivity and is equipped with a large number of colors to provide many comparisons and a very small chance of getting a wrong color or a missing color. This program makes use of OpenCV. Keywords: Color Blindness, RGB Values, OpenCV.

Published: February 2023

Drought indicator systems help decision-makers to understand how and where the drought occurred and to take measures from the Drought Management Plans. The main goal in the Water Framework Directive (WFD) is the achievement �good ecological status�, but the Article 4.6 allows temporary deterioration of the status, occurred as a result of so called �prolonged drought�. Reduction of natural water resources such as rivers, lakes, aquifers, is associated with the reduction in available water resources for water supply, environment, etc. (so called �socio � economic� drought). The severity of the �prolonged drought� is related to its duration, specificities of the river basin, reservoir management and impacts. The research is related to the system of drought indicators developed in NIMH (http://hydro.bg: Standardized Runoff Index, SRI; Standardized Precipitation Index, SPI; Soil Moisture Index, SMI) and its improvement at River Basin level. A new approach for integrated analysis of the indices of the NIMH system, the indicators used by the Ministry of Environment and Water (MoEW) - inflow and levels of reservoirs, groundwater, etc., has been developed. Thus, from the first months, the so-called hot spots and critical areas are identified - reservoirs, watersheds and river basins for which drought indicators identify drought and/or whose regulatory capabilities have declining potential and are at risk in the event of prolonged drought. Emphasis is placed on those hot spots where the precipitation deficit takes place in the reservoir watersheds. A system of criteria and drought indicators to identify �prolonged droughts� have been experimentally applied. A joint analysis of the SRI, SPI, SMI maps (http://hydro.bg), the developed maps for inflow and volume of complex and significant reservoirs from Annex 1 of the Water Act, etc., was performed. For assessment of the indicators for the reservoir inflow a scale of inflow used by the MoEW is proposed. For the indicator available volume, experiments with the Percent from reservoir capacity, Standardized Status Index, etc., were conducted. Drought periods in Bulgaria are analyzed, especially prolonged drought 2019 � 2020. The approach supports the operational application of the NIMH drought indicator system in the practice of the MoEW and the Drought Management Plans realization.

Published: February 2023

The development of sustainable ecosystem services worldwide is one of the priority issues in the context of environmental protection. Sustainable use of ecosystem services ensures the conservation of natural resources for future generations. In the cold climate of the lowland river, there is a highly seasonal hydrological regime affecting the use of ecosystem services. Biodiversity in flood meadows depends directly on seasonal variations in water levels. Balanced hydro generation and water regulation can pose risks to biodiversity. The aim of this study is to analyse the impact of the hydroelectric power plant on the water level of flood meadows and its impact on biodiversity in the Natura2000 area. During the study nine monitoring stations were set up for the Svete River section in the administrative area of Jelgava municipality. Water level measurements were made one year at one hour interval. The flow rate measurements were performed monthly. The results of the study show that the hydroelectric power plant has a significant impact on the downstream, where increased river overgrowth wit plants is observed, because of the inability to provide ecological run-off during the summer. This study offers to optimize water flow rates by upgrading the operation of hydroelectric power.

Published: February 2023

In a climate change scenario, natural disasters as wildfires and their consequences are expected to increase. Besides the loss of vegetation, wildfires have severe effects over mountain environments, frequently affecting slope stability and eventually provoking further economic losses and casualties. The risen probability of flash flooding and debris flow is recognized to depend on a modification of the soil hydrological properties, in particular of the soil infiltration capacity, in burnt terrains. Past studies identified different trends of soil infiltration recovery after fire, depending on the site environmental characteristics and on the original soil conditions. Even though wildfires are common in the Alpine area, studies on the hydrological impact of wildfires are mainly from the US, Australia and partly from the Iberian Peninsula. This work aims to investigate the impact of a wildfire occurred in 2019 in the Southern Alps and to retrieve recovery trends for the calibration of a simple 1D hydrogeological model. The effects of the wildfire and their variations over time were evaluated on three different spatial scales: satellite imagery, field monitoring (infiltration tests) and laboratory rainfall simulations.
THE VULNERABILITY ANALYSIS OF A MOUNTAIN RIVER ECOSYSTEM ASSOCIATED TO ANTHROPIC ACTIVITIES, IN A TOURISTIC AREA IN ROMANIA

Published: February 2023

The population and economy growth in the past years, and subsequently the increased demand for freshwater, led to an increased pressure on water resources. The quality of surface water is affected by anthropogenic factors, such as: domestic sewage, industrial activities, agricultural activities, recreational activities, land use change, urbanization. Therefore, the impact on surface water vulnerability is higher in large urban areas or in urban areas with intense touristic activities. The analysis of water vulnerability in such areas is important in order to develop sustainable water resources management strategies. In this paper, a vulnerability assessment index was developed in order to analyze the surface water vulnerability on a section of Prahova River (from source to Breaza city). The urban areas located in this section of the river are characterized by intense touristic activities, with a large influx of people. The vulnerability index was developed using GIS tools and analyzing specific indicators such as: different types of land use and in particular urban areas, length of the roads in the study area, resident population, influx of tourists, animals, slope and sinuosity of the river. The river was divided into sectors and a vulnerability index was calculated for each sector. Moreover, a comparison analysis was done, considering a second scenario for the year 2020 in which the number of tourists was highly reduced, in order to investigate the impact of this indicator on the water vulnerability. The results, represented by the vulnerability map showed that the most vulnerable sectors of the river are situated in proximity to urban areas and furthermore, the touristic activities increase the impact on surface water resources.

The soils potential is the result of interdependence between the characteristics of the vegetation and the natural environment, also the level of production is the result of the influence of determining factors: natural environmental factors and technological factors. The influence of biotope relief factors on the above-ground vegetation is a direct consequence of the altitudinal differentiation of climatic conditions, a vegetation layer and implicitly a rather varied and complex area soil cover. It is unanimously appreciated that in order to have a rich and quality harvest must be ensured the quantities of fertilizers and the necessary amendments to improve the nutritional conditions of the crop species or grassland areas.
In this study we use a qualitative-productive evaluation (QPE) of grasslands soils represents according to the degree of favorability (suitability) using as a comparison tool technical indices or rating notes. Based on this study a soil map and legend were developed depending on the specific properties for each soil and land unit following each group of soils limitations. The results showed in the studied area the reaction of the soil (pH) is generally weakly acidic, the weighted average pH value being 6.68, with phosphorus supply generally medium, the weighted average phosphorus content being 22.67 ppm. The supply of potassium to the soils is very good, the weighted average potassium content being 208 ppm K.
Compared to those results, depending on the specific properties for each soil and land unit was identified the soils limitations and a specific fertilization to comply with the European Code of Good Agricultural Practice so as to ensure good future production potential.
THE APPLICATION OF THE LASER DIFFRACTION TO DETERMINE SOIL TEXTURE AND INFLUENCE ON SOIL TEXTURE CLASSIFICATION
Authors: Paseka Stanislav
Published: February 2023

One of the most important properties of soils is soil texture. Soil texture is defined as a collection of soil particles of different sizes � i.e. grain size. Particle analysis is a laboratory process that causes material dislocation into individual particles. The methods for the actual soil grain size analyses are based on the standard. This is the sieving test, the density test or the pipetting method. These methods are well known and widely used. The soil is then usually classified according to the triangular diagram. Recently, the laser diffraction method (LDM) is beginning to appear. However, this method is still not established as a standard methodology in the European Union. It has the advantage of simplicity, speed and accuracy of particle size measurement.
The aim of the paper was (I) to compare the results from laser diffraction measurements with the results from an accredited laboratory and (II) to analyze the influence of different methods on soil texture classification. The methods used were laser diffraction using ultrasound and without and the commonly used pipetting method in an accredited laboratory.
The paper confirmed the possibility of using laser diffraction to determine the grain size of the soil sample. The comparison of the results showed whether the laser diffraction is comparable with the common and standardly used method and what is the impact on the determination of the soil texture.

THE POTENTIAL OF USING DREDGED SOIL IN PORTS IN LATVIA
Authors: Abele Lilita , Azens Gints
Published: February 2023

Reconstruction of ports, including dredging, is intensifying all over the world. Dredging is used to dredge ports - a type of excavation that is carried out underwater or partially underwater. Dredging helps to maintain waterways and ports navigable. It is a complex process consisting of stirring, lifting, transporting and disposing of the dredged material. The material obtained by dredging may be disposed of in the vicinity of the port or transported to another location by barge or by pipes in the form of liquid suspension. The disposal of dredged material has a significant impact on the environment. For example, changes in shore morphology during dredging can affect local habitats, cause changes in water currents and waves that can affect navigation, cause changes in water quality, affect benthic fauna, and fish spawning and cause other changes whose longterm effects on the environment are not foreseeable.
The problem of the research: most of the dredged material obtained in the process of dredging in the world is included in the re-use of resources, creating land areas, restoring the coast affected by coastal erosion and elsewhere, at the same time, the dredged material obtained in the port of Liepaja is disposed at the sea spoil grounds. As dredged material in the port of Liepaja consists mainly of solid, firm clay, stones and sludge, it could be used as a raw material in various sectors of the economy. For example, during the last port dredging project, a total of 2.7 million m3 of dredged material was exhausted in the port of Liepaja, which was disposed of at the sea spoil grounds and which could be used as a resource in implementing the principles of the circular economy and without harming the environment [10].
EXPERIMENTAL PERFORMANCE OF SOLAR THERMAL COLLECTOR SYSTEMS IN REAL OPERATION CONDITIONS IN LATVIA
Authors: Gendelis Stanislavs , Mikelsons Mikus
Published: February 2023

The data from three solar thermal collector systems installed in dormitories of the University of Latvia in Riga are analysed in detail to obtain parameters that characterise the operation of such systems in real operation conditions in Riga, Latvia. All the systems were installed in 2019�2020 and the data for one full year is available for the study. The area and the power output for the observed solar thermal collectors are similar�63 m2 with 51 kW for each. The differences exist only in the orientation of the collectors depending on the building�s roof, tilt angle and the mounting combination (one or two rows). Each system is equipped with hot water accumulator tanks with a total volume of 3000 l to ensure hot water supply during peak demands (typically in the mornings).
Analysis of the recorded data from the systems shows the actual energy produced with the help of solar thermal collector systems in real operation conditions. Calculations determine the actual energy production, which is estimated in the range of 320�380 kWh/m2 annually, or 395�470 kWh/kW per installed power output depending on the system�s spatial orientation. The most efficient is a south-east-oriented collector at a 25� tilt angle, reaching 50% efficiency (from available energy) during the summer days. The difference from the planned 500 kWh/m2 is explained due to higher cloudiness and the fact that the system is not even activated on cold days.

A study was made of the influence of ZSM-5 zeolite on the composition and properties of the products of fast pyrolysis of flax shives in the temperature range of 350-750 �C. Zeolite ZSM-5 increased the heat of combustion of gaseous products, as well as the content of methane, ethylene, hydrogen, and carbon dioxide, which is probably associated with the processes of cracking of volatile products passing through a layer of a catalyst heated to high temperatures. The synthesis and study of zeolite catalysts ZSM-5 containing transition metals (Fe, Co, Ti, V, Mn, Zn, Cu, Cr) with a 2% metal concentration in the process of deoxygenation of volatile products of fast pyrolysis of waste biomass of plant origin. According to the activity in the deoxygenation process, the metals studied during the work stage can be arranged in the following descending order: Pd > Pt > Co > Cu > Ni > Fe > Cr > Mn > V > Ti > Zn.The 2%Co-ZSM-5 catalyst showed high activity in the deoxygenation process, since its use led to an increase in the low volumetric calorific value of the fast pyrolysis gas by 1.3-1.5 times, as well as to a decrease in the tars content.

Recently, the study of new methods of extraction from vegetable raw materials, such as ultrasonic extraction, microwave extraction and extracritical fluid extraction, has become widespread. The results of the study of ultrasonic extraction in the literature showed that this process provides higher selectivity, has a shorter duration, reduces energy consumption and harmful emissions into the environment. And it is also made in the equipment which design is much simpler than the equipment for pressing. In addition, ultrasonic extraction allows to obtain products of higher quality than simple extraction. This method is considered environmentally friendly because most of the solvent used for extraction can be recovered. The development of new high-intensity extraction equipment operating in ultrasonic conditions requires the establishment of quantitative kinetic characteristics and diffusion coefficients of the extraction process from vegetable raw materials using ultrasound from different solvents and raw materials.

The priorities identified by the EU�s and national strategies and the main target areas promoted by the legal regulations concerning this area are precision food production, investments and developments, and � in the area of ensuring the resources needed to achieve these � a more efficient production, the improvement of sustainability and food safety. To achieve these objectives, the European Union has identified the widespread introduction of precision technologies using digitization technology in the food industry. As an effect of the implementation of DAS on the food industry for processing, the environmental pressures will decrease in mass production too. Food economy will be able to produce healthier, higher quality foods. In this research we are analyzing the achievement of the Digital Agricultural Strategy of Hungary of 2019- 2022, the targets of the Common Agricultural Policy as of 2020 and the main targets of the Green Deal, in the case of model farms we have selected. Our purpose is to examine the impacts of precision technologies on the enhancement, thrift, profitability, sustainability the efficiency of production and on the food chain security in the case of medium-sized model food industrial plant.

Improving the performance of the gypsum binder is possible by strengthening the gypsum matrix. The increase in strength is ensured by the introduction of a complex of mineral and chemical additives. The use of waste as components of such a complex solves a set of problems. The market is saturated with competitive and high-quality materials. Designed materials meet modern requirements. In addition, the problems of waste disposal, freeing up space, environmental protection and reducing the resource intensity of production are being solved.
The purpose of the work is to obtain energy- and resource-saving compositions of gypsum dry building mixtures with improved physical and mechanical characteristics through the use of modifiers from the resources of the local raw material base. The addition of basalt waste and hydro-removal ash to the gypsum binder as part of a complex of mineral and chemical additives ensures the formation of a hardened modified gypsum stone. During the research, regularities were established for the influence of the components of the additive complex on the properties of the gypsum binder. Optimal ratios between gypsum binder and modifiers have been selected. The microstructure of the modified gypsum stone has been studied. The positive effect of the complex on the structure of gypsum has been proven.

The presented work provides a detailed view of climate change and its impact on the temperature conditions in Slovakia. It analyses the occurrence of tropical and supertropical days from the past to the present in the most fertile part of Slovakia. The results show that there has been an overall increase in the number of tropical and supertropical days in the Danubian Lowland and the Danubian Hills between 1961 and 2020, which is partly due to an increase in average temperatures and weather extremes. The locality of Ziharec recorded the largest number of tropical days in the last decade (369 days). If we compare it in this locality with the coldest decade 1971-80, when it was 117 days, then it represents a percentage increase of 135%. For comparison, the increase of tropical days in the locality Banska Stiavnica is from 14 days to 105 days (650 %) in a decade and the locality is not in the warmest areas of Slovakia. For agriculture in the Danubian Lowland and the Danubian Hills, the overall increase in tropical and supertopic days, together with the uneven distribution of precipitation, has a negative effect on the drying up of the country. Rising temperatures and an increase in the number of tropical and supertropical days could be partly positive, especially in the growth of phytomass and higher biomass yields, provided if there is a sufficient supply of water in the soil.

Global climate change is one of the most acute environmental problems of our time. Among the methods of capturing CO2 in industrial emissions are chemical, physical and biological. The latter are based on the use of living organisms that absorb carbon dioxide in metabolic processes, and the subsequent use or burial of their biomass or their metabolic products. One variant of organisms used to capture carbon dioxide biotechnologically are microalgae. In the present study, the efficiency to capture carbon from the exhaust gas was compared for three microalgae species - Chlorella vulgaris, Scenedesmus obliquus and Spirullina platensis. A photobioreactor was assembled, consisting of transparent sealed flasks, a CO2 supply system, an oxygen removal system, and an illumination system. It was found that C. vulgaris was characterized by the largest increase in biomass (2.68 g l-1), and Sc. obliquus � by the lowest one (2.21 g l-1). The biofixation rate, the content of proteins and lipids were estimated to be 0.31, 0.26 and 0.29 g CO2 l ?1 d ?1, 64.0, 15.0 and 22.0 %, 15.0, 17.0 and 23.0 % for C. vulgaris, Sc. obliquus, and Sp. platensis, respectively.

The study of meteorological-climatic phenomena, especially of extreme phenomena that have become more and more frequent, has gained greater significance, given the increasing awareness of the importance of preventing material damage. Thus, monitoring and analysis of atmospheric risk phenomena helps local and national authorities whose duty is to protect the population and property of any kind, and early warning regarding the occurrence of such phenomena is useful to each individual.
The western and north-western part of Romania, like the whole country, due to its geographical position, in the temperate area, is exposed to a wide range of risky meteorologicalclimatic phenomena which may potentially occur throughout the year. The present paper aims to identify certain meteorological aspects, which most correctly express the extreme character of the manifestations of some meteorological parameters. The data provided by the Banat Crisana and Northern Transylvania Meteorological Centers highlighted the evolution of certain risk parameters from two representative meteorological stations in these areas, Timisoara and Satu Mare, over a period of forty years.
