STUDY REGARDING THE PREPARATION OF TECHNICAL DOCUMENTATION NECESSARY TO MODERNIZE THE ROAD THAT CROSSES THE BUCOVAT-LEAMNA, DOLJ AGROTURISTIC AREA
The work aims to carry out topo-cadastral surveys for the design of rehabilitation and modernization works of the county road that crosses the Bucovăț-Leamna agrotourism area, near the city of Craiova, which is in full development and evolution. For the field application of all lifting works, a state-of-the-art modern equipment such as GPS technology and total stations was used, and the combined method GPS-Total Stations was used as the surveying method. Their use has led to relevant results in terms of the efficiency, accuracy and effectiveness of such a surveying project. Also, for the data processing, the method of transferring the data measured in the field, from the topographic devices directly to the computer, with the help of special programs was used, after which they were processed automatically obtaining the absolute coordinates of the points with the precision required by the beneficiary, in compliance with all legal requirements, applied to such works. The points were represented with the AutoCad program, obtaining the location and delimitation plan for each large-scale road body, which allows the designer to perform the design work in great detail, with great fidelity and precision. At the same time, it ensures a very high precision of tracing and execution of all the rehabilitation and modernization works of the studied road, of great local and county interest

The purpose of the work is to produce the technical documentation necessary to prepare the design and execution of all the construction works, which will be executed for the modernization and rehabilitation of the road taken in the study. In this sense, the work team carried out a preliminary topographic study based on which an overview of the situation existing on the field was formed, which also offered the possibility of the designer choosing the most suitable design and execution solutions. Topo-geodesic works were performed using the combined GPS-total station method, using modern equipment that ensured high accuracy and high economic efficiency. The final documentation obtained is of the highest technical and scientific level, respecting all the norms and requirements of precision and quality imposed by the regulations and laws in force, such engineering works, these being verified and approved by OCPI-Mehedinti
STUDY ON THE PREPARATION OF THE TECHNICAL DOCUMENTATION REQUIRED FOR REGISTRATION IN THE LAND BOOK OF A PROPERTY IN KLADOVO – SERBIA
The study is carried out in collaboration with Serbian students from the MTC, from the Faculty of Agronomy of the University of Craiova and with a company from the same country, in order to make a comparison and analogy between the methods and procedures of surveying used in the two countries (Serbia and Romania). The paper presents a case study conducted in the town of Kladovo in Serbia in which a private property was taken into account, which must be registered in the Land Book. In order to solve all the requirements of such a work, a modern and new method was applied, used more and more in the topo-cadastral surveys, namely the combined method GPS and total station. From the surveys carried out in the field and processed at the office, it is found that the methodologies and working procedures are identical to those used in our country. It is also found that the equipment used is very modern and high-performance, which allowed to obtain a very high precision and a high economic efficiency of the work. In the end, the technical documentation prepared strictly complied with all the requirements of the legal norms imposed in Serbia and was done with great precision, which allowed it to be submitted to the office of the Land Book and the registration of the property studied in it. The significant difference between the technical documentation prepared for this property in Serbia and the documentation made in Romania is the Gauss-Kruger coordinate system in which the boundary points were determined, compared to the 1970 Stereographic system used in our country
STUDY ON TOPO-GEODEZIC WORKS FOR THE REHABILITATION OF THE TRAMLINE IN THE FORD-CRAIOVA AREA
The present paper addresses a very complex and difficult research topic, but of great current importance and wide applicability in practice. We affirm this because it is very well known that the road and rail infrastructure 30 years after the revolution is in a very precarious state, we can say very sad, because its rehabilitation and modernization has been done at a very slow pace. Therefore, the working team considered that approaching such a topic of great interest, is beneficial first of all for the practice, since the volume of works of such nature must increase considerably in the future and not lastly it is very valuable from the academic and scientific point of view. In order to solve the thematic approach, the working team used the latest and topographic devices and programs for processing the measured data, which allowed to obtain relevant and very correct results. The working methodology was perfectly adapted to the objective pursued, the situation existing on the ground and the precision imposed by the beneficiary, an aspect that led to obtaining a high execution efficiency of the works, but also to a high economic efficiency, because the time of execution, the volume of works and the number of personnel was greatly reduced
ROMANIAN COUNTRYSIDE - SUPPORT FOR THE DEVELOPMENT OF SUSTAINABLE TOURISM
This paper is focused on presenting the particularities of the Romanian rural space from a touristic point of view with its advantages for the tourists and as reason for supporting the development of sustainable tourism. The specificity of natural capital is amplified by spectacular landscapes, varied configuration of land relief, favourable climatic conditions (reduced frequency of negative phenomena, absence of excessive temperatures), therapeutic value and abundance of natural factors (mineral waters and thermal-mineral waters, curative mud, topoclimate and microclimate, etc.), flora and fauna, etc.The natural capital, for which the Romanian rural area represents a „geographic personality”, must be doubled in time by the tourist vocation.Romania holds an immense treasure of archaeological remains, historical, architectural and art monuments, as well as a priceless patrimony which attests the evolution and continuity of work and life on these lands, the development of the culture and arts of the Romanian people. This entire cultural-historical fund represents a significant part of the potential tourist offer (the so-called potential secondary offer) and a component of the tourist image of Romanian on the international market
UTILIZATION OF TOTAL STATIONS IN THE WORK OF DETACHMENT A PROPERTY
The detachment of a property is common in recent years, primarily due to the modification of the urban plans, by the extension of the urban areas to the detriment of the arable lands. Thus, there is the possibility of lotizing larger terrains of the order of thousands of square meters in several plots of different sizes, generally 250-600 m2, which are then sold for the construction of new dwellings. In the paper is presented as a case study such a detachment of a property, using for field measurements the total station
Assessment of Antifungal Activity of Lactic Acid Bacteria Strains Against Bread Spoilage Fungus Aspergillus ochraceus
Lactic acid bacteria (LAB) are generally recognized as safe and can be used against fungi that contaminate various food commodities. The aim of the research was to select LAB strains with high antifungal activity for the biocontrol of Aspergillus ochraceus. The antifungal activity of eight strains of lactic acid bacteria has been evaluated by overlay assay method against the spoilage fungus, Aspergillus ochraceus isolated from white bread. The antifungal effect was assessed by co-cultivation of lactic acid bacteria strains and Aspergillus ochraceus in liquid media and mycelium growth inhibition was monitored for over 14 days. The LAB strains Lpl, LAB 43 and LAB 13 presented intense antifungal activity with large inhibition zones of fungal growth and sporulation, but smaller for Lpa and LAB 15 strains. Total inhibition of mycelia growth was induced by the strains LAB 43, LAB 13 and Lpa. The strains LAB 15 and LAB 35 had a moderate inhibition activity on the mycelia growth. The results of this study demonstrated the antifungal activity of several LAB strains by overlay assay and by co-cultivation method. Therefore, it was confirmed the inhibitory effect of the strains LAB 43 and LAB 13 against Aspergillus ochraceus. The experiment revealed that these LAB strains could be further used as biocontrol agents
Comparative Antifungal Effect of Lactic Acid Bacteria Strains on Penicillium digitatum
Lactic acid bacteria (LAB) are natural alternative to chemical preservatives for fruits. The aim of the research was to select LAB strains with high antifungal activity against Penicillium digitatum for the biopreservation of fruits. The antifungal activity of eight lactic acid bacteria strains has been evaluated against Penicilliuum digitatum isolated from orange, by overlay assay method and by optical microscope examination. The reversion of inhibition zone after 96 h was recorded as a fungistatic effect while those with inhibition zone for at least 7 days were recorded as fungicidal. The antifungal effect of efficient LAB strains was assessed by comparing inhibition of fungal biofilm formation in liquid media. The strains Lpl, Lpa, LAB 13, LAB 15, LAB 43 and LAB 58 presented intense antifungal activity with clear inhibition zones diameter over 20 mm. The microscopy evidenced atypical hyphae and delaying of conidial chain formation. The strains Lpa, LAB 13, LAB 15 fully inhibited the mycelia growth, strains LAB 43 and LAB 58 partly with delaying of biofilm formation on the surface of culture medium. The results of comparative antifungal activity of LAB strains evidenced the highest inhibition of fungal biofilm formation and structural damages of hyphae and spores caused by the strains Lpa, LAB 13 and LAB 15. These strains could be efficient biocontrol agents of Penicillium digitatum in fruits
