Most human beings want to use medicinal plants to treat some diseases. This means that we want to return to nature to prevent some diseases and pains. Although diseases are currently being treated more often through medicines of synthetic origin, the use of some medications leads to certain damages to the body. Therefore, the importance of medicinal plants and their products is increasingly recognized and public confidence in their use is constantly strengthened. In my Case Study -,,The Benefits of Using the Medicinal Plants”, I concluded that: it is important to protect some green areas (100% of people agreed with this); it is important to protect the plant species with a risk of extinction (86,3% of people agreed with this); we prefer herbal products (86,3% of people agreed with this); it is important that the medicines be prepared only from medicinal plants (76,5% of people agreed with this); it is important to focus only medicinal plants and their products (63,7% of people agreed with this).

By studying the literature and the information available on various sites, we noticed that Sweden is the country with the most advanced and efficient waste collection and recycling system. Sweden is a top performer when it comes to sorting and recycling its waste and is in the rare situation of lacking garbage at its incineration centres, which produce enough electricity to supply 250,000 homes and heating for 950,000 homes. Swedish municipalities are individually investing in futuristic waste collection techniques, like automated vacuum systems in residential blocks, removing the need for collection transport, and underground container systems that free up road space and get rid of any smells. In the Romania, each local authority has its own system, making it difficult for residents to be confident about what they can recycle and where. We think we need more of a coherent national strategy in Romania to the collection of recyclable materials, rather than the current approach, whereby it is largely left to individual local authorities to determine their own collection policies.
Don’t waste more time and money – let’s get started! A holistic mindset is the key! Getting the whole system and industry involved creates the best conditions for the changes and actions needed to make waste management truly sustainable. It means getting the municipal sector (where the infrastructure is, or should to be) and the private sector (which sells the technology and services) to work together. Both inside municipalities and between municipalities!
Making this happen creates scope for long-term planning – and short-term action. For getting priorities right and starting at the right end of the chain. And for agreeing who should do what and why.
This paper aims to draw the attention of all people to the importance of separate collection of waste and reuse. For this purpose we created two questionnaires which we addressed to all categories of people in terms of age and social status. Surveys have accumulated a total of 154 and 117 responses, respectively.

A new laboratory method was proposed to establish an easily performed standard for the determination of mobile soil water close to real conditions during the infiltration and redistribution of water in a soil. It consisted of applying a water volume with a tracer ion on top of an undisturbed ring sample on a pressure plate under a known suction or pressure head. Afterwards, soil water mobility was determined by analyzing the tracer-ion concentration in the soil sample. Soil water mobility showed to be a function of the applied water volume. No relation between soil water mobility and applied pressure head could be established with data from the present experiment. A simple one- or two-parameter equation can be fitted to the experimental data to parameterize soil water mobility as a function of applied solute volumes. Sandy soils showed higher mobility than loamy soils at low values of applied solute volumes, and both sandy and loamy soils showed an almost complete mobility at high applied solute volumes.

Since the dawn of man, our species searched for better ways to feed themselves, by developing more efficient methods of hunting, animal / vegetable domestication, food preservation by physical methods, and finally, by adding molecules to food in order to enhance flavours or to preserve it. Today, more than 2500 additives are intentionally added to food in order to keep certain properties or to extend shelf life, while many others were banned throughout the years, some of them at a global level and others only in specific countries. In essence, food additives are substances added to food to preserve flavour or enhance its taste, appearance, or other qualities. We distinguish two important categories of food additives: artificial and natural ones. No matter the origin is, they both present advantages or disadvantages. On the one hand, synthetic substances are, obviously, cheaper and easier to produce than the natural ones, but in the same time they can be the major cause of a variety of diseases. On the other hand, natural substances are an easier way to a healthier life, if they are used in the right doses. Also, we have to be aware that their price can be even twice higher compared to the artificial additives. This paper attempts to highlight the benefits of natural additives, their synergy and potency as a great leap from synthetic additives that in most cases have a single effect on food.

Groundwater quality monitoring management requires the implementation and/or expansion of routine groundwater quality monitoring programs in all villages in the counties of Romania. While the standardization of sample collection and laboratory testing protocols is essential, the ability to provide timely public notification is an equally important element. In preparation for the implementation of the groundwater quality monitoring management programe we investigated the use of IDEXX Colilert-18, IDEXX Enterolert E, Quanti-Tray/2000 (IDEXX) as a means to reduce the time necessary for public notification of freshwater quality while still providing accurate and consistent test results. The fact that IDEXX decreases the time from sample collection to public notification by over six hours coupled with its ease of use and consistent results make this method an attractive choice for the implementation of groundwater management programs.

Living organisms are known for their ability to adapt to environmental changes, to evolve to overcome the challenges these new environments they encounter, and microbes are no different. They have an outstanding ability to adapt to differences in environments, to different antimicrobial substances which are synthesised in order to counter them, or to quickly multiply to overcome their inevitable fate if they chose to not adapt. And that is extermination. Another factor that plays nicely with them is the chaotic usage of antibiotics, which leads to these microbes’ natural ability of developing an anti-antibiotic behaviour.

On the territory of Romania, we find a multitude of soils that have a special character from the point of view of physical and-mechanical behaviors, which can raise real problems without a thorough experience and a particular engineering approach. In Romania there are many regions in which there are found soils of low consistency, more specifically soft clays. The behavior of these clays, under the influence of mechanical stresses, has very distinct characteristics, namely: thixotropy and consolidation. Knowing the physical, chemical and mechanical properties of these soils is very useful in establishing engineering measures that will lead to a source of risk as small as possible. In Romania, during the construction of highways, there have been major phenomena of instability and bearing capacity failure of the foundation ground made of soft clays under the loads induced by the embankments of the infrastructure. The Sebeş - Turda highway, in the sector between km 63 + 700 - km 64 + 000, crosses the Stejeriş Lake through an approximately 500 m long viaduct.Alternatively, to this solution, the builder initiated the construction of a fill in the lake as a platform for the highway sector. The filling was constructed of sand and gravel aggregates, all embedded in a soft clay matrix with insufficient characteristics to bind the blocks together and form a whole. Thus, there have been mudslides and landslides in the lake and in the remaining filling there have been identified active landslides towards the lake.

Nowadays, there are many controversies around GMOs, mainly due to the lack of information, but also to the fact that the technology of obtaining the transgenic organisms is relatively new and therefore unknown by ordinary consumers. Many people believe that GMOs are harmful to human and animal health but also, for the environment. While some of these claims have been proven to be true, most of them are just speculations. Despite all the backlash, it has not been scientifically proved that GMO consumption is more dangerous than organic food. Regarding the environmental potential issues, in order not to bring ecological imbalances, the states that have embraced GMO breeding and cultivation have adopted very restrictive regulatory rules. This way, both ecosystems and food are secured. The present paper tries to detail, besides advantages and disadvantages, some myths and facts about GMOs.

The study was designed to investigate the effect of the two systems (aquaponic and hydroponic) on lettuce yield and quality. The experiment was conducted within the laboratory C01 Environmental Sciences, FIFIM. The two systems were monitored weekly through the following parameters: pH, CE, NH4, NO2, NO3, KH, PO4 using colorimetric kits named, JBL test. Regarding the growth and development of the lettuce, the length of the lettuce was measured every three days. In addition to measuring the growth of the leaves, the lettuce was also analyzed in the form of dry substance. As a result, it was proved that at pH values were generally between 6.5-8.4 pH and CE between 1.37-1.43 dS / m-1. For the aquaponic tank, the concentration of nitrates decreased from 240mg / l to 60mg / l and phosphates at 3.6 - 2.0 mg / l. This results in a good absorption of the roots of the lettuce plant. In comparison to the hydroponic system, where the concentration of nitrates and phosphates was higher. in the hydroponic system, the lettuce had an average growth of two cm every three days, and in the aquaponic system it had an average growth of three cm every three days.

The aim of this study is to determine the air pollution occurring in city centers or it’s around by means of Unmanned Aerial Vehicle (UAV) equipped with some of the sensors. Today, the air quality in the city centers is realized via stationary air measuring stations located at the determined points of the city. This method provides very safe data depending on the number of stations that make measurement. However, when the city centre is rugged and the measurement period is considered, it is clear that it is not an efficient method. In this study, a more useful measurement method will be produced by using an UAV which is also a practical method to solve this problem. It is planned to measure some of the air pollutants such as CO2, CO, NO2, CH4, and some meteorological parameters such as temperature and pressure, using a modular UAV system to be designed in the study. Due to the advantages of the modular design system, a practical measurement can be carried out for different gases if required.

Purification technologies have been rapidly evolving lately due to the large number of applications that have been made, both for city and industrial wastewater use. An important direction of evolution is related to the development of monitoring devices for the operation of sewage treatment plants. Applications that tracked performance parameters and quality indicators highlighted optimal exploitation technologies and technologies that ultimately led to increased efficiency and lower costs. In purification, the critical process indicator is "nitrogen"; reducing and framing this indicator within the limits imposed by legislation implying the inclusion of all quality indicators. The development of continuous nitrogen monitoring devices has allowed the purification, nitrification and denitrification processes to be balanced, and the development of appropriate operating and adjustment programs. The control of the ammoniacal and nitrate nitrogen treatment is the best option for optimizing the operation of the treatment plants. In the material are presented the process philosophies and the results obtained from the regulation of the functioning of the nitrogen treatment plants Continuous monitoring and regulation ensures the reduction of impacts on water resources.

The use of Unmanned Aerial Vehicles (UAVs) for surveying is now widespread and operational for several applications – quarry monitoring, archeological site surveys, forest management and 3D modeling for buildings, for instance. UAV is increasingly usedby land surveyors especially for kinds of projects. It is still ambiguous whether UAV can be applicable for smaller sites and property division. Therefore, the objective of this project is to extract an orthophotomap, which can be used later by the land surveyor engineer in the field of cadaster, to vectorize correctly a topographic plan of the studied area. In order to achieve the correct result, the orthophotomap was created using a UAV, and more specific TRIMBLE UX5 HP. The flight schedule was prepared in the office with “Aerial imaging Desktop” software, and for the processing of the resulted photos was used “TBC - Trimble Business Center” software. Both of the softwares are provided by Trimble, the manufacturer of the UAV. The main problems associated with using a UAV are the level of precision and the visualization of the whole area. The results indicated that the precision is quite satisfactory with a maximum error of 5.33 cm for the rest of the model.

The main source of food comes from agriculture, depending on the factors of environment, light, temperature, water, air, soil, plants grow and develop. One way of efficiently monitor the development process of the plants is remote sensing. Using free-of-charge data, such as Sentinel-2, we can compare the condition of the harvest in different years with the help of the various indices computed from the many satellite bands, bands in the visible spectrum with a resolution of 10 m and the invisible spectrum, resolution shifting between 20 and 60 m. In this study, we want to focus on climate change and how it affects the condition of crops using satellite data for three consecutive years in the same area. Lack of precipitation and abnormal temperatures for certain periods of the year can affect crops and reduce food quality and quantities.

This paper aims at discussing about the evolution, throughout the years of private areas in the North side of Herăstrău Park in order to highlight the changes brought by urbanization and housing in this area. This paper will focus on the quantitative aspect of the problems derived from these aspects .The World Health Organization recommended 50 m2 of green space per capita, whereas the Government Emergency Ordinance no.114/2007 implies that the local authorities have the obligation to ensure at least 26 m2/capita. This numbers are not achieved in Bucharest due to different factors, one of them being the conversion of public spaces from parks into private spaces (Tudora et.al., 2018, p.120). One of such affected parks is Herăstrău, the largest park of Bucharest, listed in The National List of Cultural Heritage (code 47 B-I-s-B-17874). Even though the park is officially acknowledged as heritage, the park has suffered a decline of its surface due to the extension of private buildings and built areas. These are due to numerous causes that go from unfollowed regulations to misinterpretations of the law and more (Mexi et.al., 2018, p.3).

The paper aimed to present the main steps necessary to determine photo-coordinates and the process to correct them for systematic errors, such as radial distortion, refraction and earth curvature which is also known as image refinement. Image preprocessing is a technique which is used to enhance raw images received from aerial photocameras, placed on drones, airplanes, satellites or other aircrafts for various engineering applications with a good accuracy. Photogrammetric original data obtained are usually geometrically distorted due to the acquisition system and the movements of the platform. So, we inserted the diapositives into the measuring system (e.g. stereo-comparator or analytical plotter) and measured the fiducial marks in the machine coordinate system. Then, we compute the transformation parameters with a similarity or affine transformation. The transformation establishes a relationship between the measuring system and the fiducial coordinate system, and translates the fiducial system to the photocoordinate system. Finally, we corrected photo-coordinates for radial distortion (by linearly interpolating with the values given in the calibration certificate) and other systematic errors.

The Unmanned Aerial Vehicle (UAV) technology has gained great attention in recent years. It is viewed as a low-cost alternative for local large scale aerial mapping and other applications requiring the modeling of a relative small area only. In this paper we present the eBeeX UAV from SenseFly used in acquisition of aerial images and the Pix4DMapper software for data processing for generating a 3D model of a hotel from Spain. The data used in this project are available on https://www.sensefly.com/education/datasets/. Data management in cases where the number of images is high is also very important. The use of UAVs is also advantageous because it may be used for tasks requiring quick response, including in the case of the inspection and monitoring of buildings. It is demonstrated that the UAV system for low altitude aerial photogrammetry can be used in the construction of 3D building production, and the technology solution in this paper offers a new, fast and technical plan for the 3D expression of the city landscape, fine modeling and visualization.

There are all kinds of residues, from either plant processing or harvesting and although some of them can be integrated into the soil in order to enrich its nutritious content for further crops, there are a large number of uses for the seemingly unimportant parts left. From fodder to water filtering systems, plant residues have a variety of uses, some more surprising than others, and they contribute to the sustainability of crops and ecosystems to a larger extent than commonly known.

All over the world, especially in countries with a very strong tradition in cultivating medicinal plants, production of bio-products based on natural compounds leads to the transformation of plants in large quantities of waste, mostly unexploited. The majority of the wastes are underutilized and may cause severe environmental problems if not properly handled. Lack of cheap technological solutions for biochemical and organic remediation that could achieve gradual adaptation to environmental standards of generating pollution entities and macro-entities is the main obstacle that hampers implementation of European environmental directives. Valorization of these compounds from plants waste not only reduces environmental concerns but also improves sustainability and economic competitiveness of agro-food industries. The present paper represents a short review of the possible ways of valorization of plants waste such as lavender, mint and sage into value - added by – products.

Common Agricultural Policy (CAP) is the means of promoting agriculture in Europe and one of the oldest EU policies. It was created in 1962 and reformed successively in 1992, 2003 and 2013. The European Agricultural Fund for Rural Development is a financing instrument for the Common Agricultural Policy, which funds the National Rural Development Program, supporting the strategic development of rural areas in Romania. The National Rural Development Program 2014 - 2020 is the program that gives grants from the European Union and the Government of Romania for the development of rural areas in Romania. The main rural development priorities for the 2014-2020 financial programming period are: • modernizing and increasing the viability of agricultural holdings by strengthening them, opening up and processing agricultural products; • encouraging rejuvenation of farmers' generations by supporting the setting up of young farmers; • the development of basic rural infrastructure as a prerequisite for attracting investment in rural areas and creating new jobs and implicitly for the development of rural areas.• Encourage the diversification of the rural economy by promoting the creation and development of SMEs in nonagricultural sectors in rural areas; • promotion of the fruit sector, as a sector with specific needs, through dedicated subprograms; • Encourage local development under the responsibility of the community through the LEADER approach. LEADER cross-cutting competence improves competitiveness, quality of life and diversification of the rural economy, and combating poverty and social exclusion. The European funds provided to Romania for agriculture, which can be obtained through the Agency for Rural Investment Financing, contribute to rural development. They help farmers set up new farms or develop the existing ones, representing a very important benefit because the grants are non-refundable.

The permanent meadows in our country have a spread of about 4.9 million hectares, Romania occupying the fifth place in Europe after France, Great Britain, Spain and Germany. The meadows in our country, which represent 33% of the agricultural area, constitute a part of the national wealth, which is of major importance for the size of the foraging resources and their quality, as well as for the other functions having a beneficial effect on the protection and the beauty of the environment. Meadows are an essential element of sustainable farming systems, whichmeet the demands of healthy and high-quality food. In addition to the decisive role of providingfeed foranimal feed, meadows have an important role in rural development and the reflected environment through: conservation of biodiversity, improvement of soil fertility, symbiotic fixation nitrogen, hydrological balance, prevention of floods and landslides, carbon sequestration, landscape quality and important cultural heritage. Sustainable development is a complex process that runs through and below human intervention, aimed at the development of society, its materialization being based on the fact that the sustainable development of the whole is ensured by the sustainable development of to each part of human activity. Management of the meadow belonging to a locality is the way in which the management of a meadow is ensured, and the organization and exploitation of the permanent meadows (according to Government Emergency Ordinance – OUG No. 34/2013), respectively ( O.U.G. no. 34/2013). The guidelines for optimal management of different types of pastures are also dependent on the specific objectives and their main points are: timing and cutting technique, number of grazing animal feed per hectare in different types of meadows, chemical impurities depending on the type of soil , the presence of weeds or invasive species.

The paper aimed the rapid development of computer technology over the past decades which allows cartographers to manipulate large sets of high resolution data more or less easily. To generate 3D maps, there are a large number of input indices that influence the map creation process. There are a wide variety of graphical aspects for 3D map authors. In the framework of 3D map generation process, we can distinguish different graphic groups. The graphical aspects of modeling define the basic and semantic object structures in the database, and the graphic aspects of symbolism indicate the appearance of objects in form, color, style and other visual features. Finally, the graphical layout of the layout arranges all settings for the final scene view with the 3D map on different output media.

In order to achieve a pastoral settlement is necessary to do an initial cadastral assessment of all land in the category of use, pastures and meadows which are owned by the public and private property . The cadastral evaluation of the pastoral arrangement took into account the technical works and the existing installations, indicating the place of disposition in stereographic coordinates 1970 and determining the surface of the meadow or parts of the meadow, with the presentation of the name, area, neighbourhoods and boundaries. Also, for a good approach to the issue of pastoral arrangements, it was necessary to study all the documentation underlying the property right, including the meadow sketch or the cadastral plan. The division of meadows into lands and exploitation units has been done using the geographic and topographical aspects of the meadows and depending on the access routes and the natural boundaries imposed by the land. The analysis of altitude and meadows exposure was done using the Global Mapper application by generating the topographical plan on the layout of grasslands and a level curve plan. There has also been a 3D model of the area where UAs are arranged for viewing meadows locations in a mountainous area.

This paper presents a digitized map of the city of Timisoara based on the exposure of the main locations by adding them to the map with a geographical position (latitude, longitude), a name and a symbol that differentiates them from each other. In addition to the attributes listed above, each point of interest also includes a description that helps platform users find out more. Spatial analysis is the process of examining, modelling and interpreting the results. After spatial analyses, information about a set of geographic data can be extracted or created. Spatial data processing is performed on the basis of algorithms using the special operations of these data categories. In GIS there are four main types of spatial analysis: spatial overlay and continuity analysis, linear analysis and raster analysis. With this spatial analysis feature, GIS software is different from CAD software. Thus, the interactive map created through the ArcGIS Online program is very useful for the city of Timisoara both for residents and tourists, especially as Timisoara was designated the European Capital of Culture in 2021.

Mapping has had an essential role in history, bycapturing and transmitting models and visions of nature and social relationships. The emergence of the first maps was related to the need for orientation of the first humans and the need to delimit hunting and cultivated areas. The first aerial photographacquired from a balloon above Paris, brought a great evolution of the knowledge of the territory. We now have various images captured by a multitude of satellites, providing valuable Earth observation information. This study focuses on the Sighisoara area in order to create a geodatabase, containing maps and pictures from 1918 to the present. We used Sentinel 1, Sentinel 2 imagesfrom Copernicus Open Access Hub platform, and Landsat 8 images from Earth Explorer platform, free of charge. Image processing is made with SNAP (Sentinel Application Platform) software available for free;for Sentinel 1 images we applied a noise reduction filter, a geometric correction (geocoding based on a digital elevation model) and then cropping of the image. The Sentinel 2 and Landsat 8 optical images were used to create natural color image red-green-blue combinations of spectral bands, which were initially resampled and cropped. All the products obtained have been integrated into a geodatabase using the QGISprogram, also available for free, all data being kept for future use.

The Moon has played an important role throughout the development of human civilization. It is the only permanent natural satellite of Earth and the closest astronomical object in the universe. Between the years of 1969 and 1971 the American and Soviet space programs left a total of five retroreflectors on the lunar surface. Astronomers have been able to use powerful lasers and telescopes to perform highly accurate measurements of the distance to these artifacts. The data that have been collected have led to significant improvements in the understanding of some aspects regarding the Earth-Moon system. Lunar Laser Ranging (LLR) has influenced astronomy, lunar science, gravitational physics, geodesy, geodynamics and numerous other fields. The purpose of this research is to state the historical development of Lunar Laser Ranging, what is involved in this process, the scientific accomplishments and the importance of this experiment for future explorations.
