The influence of the exploatation of the gas CO2 and mineral water from vicinity "Popojci“ village Dolno Oriziari-Bitola on the living environment

The pollution of the underground water, concerning their easy injurance is the most important problem that the civilization is facing, present days. The protection of the surface and underground water, soil, the air is most important thing, which in the present civilization is left to be done and to release pure resources of clean drinking water for the next generations. Normally, every additional motive power on this space from Pelagonian basin should be expected to bring micro and macro changes of the living environment, which can arose multiple consequences first of all in the harmless of the underground water. It should be mentioned that every drop of dirt that falls on the surface of the soil will migrate in the depth of the soil. In this paper, gained results from the research and the quality of the mineral water and the gas CO2 are described, as well as the way of the exploitation of the mineral water and the influence of the exploitation on the living environment

Permanence of sown sward situated along the slopes of the central Balkan mountain

The state of mixed swards of red fescue, Kentucky bluegrass and bird's foot trefoil was studied. The experiment was situated along the slopes of the Central Balkan Mountain, during the period of the 1st to the 13th year of their creation. At a high degree of soil gleying, the low part of the slope, the dry matter yields were within the limits of 2.8 t/ha (1997, south-eastern exposure) up to 10.66 t/ha (1999, north-eastern exposure). At a low degree of soil gleying, high part of the slope, the dry matter yields were within the limits of 2.34 t/ha (1994, western exposure) up to 14.34 t/ha (1995, east exposure). The most prominent in productive terms for the period of the study are the variants at the east and south-eastern exposure, slightly gleyed soil. The participation of the sown species in the total forage yield is variable quantity. They reach (at their most) up to 96% in 1998, north exposure, slightly gleyed soils and up to 97% in 2000, north-east exposure, highly gleyed soils. Their share was small in 2004 (44%) and in 2006 (42%) on a western slope, highly eroded soils

Saabunud / Received 14.10.2021 ; Aktsepteeritud / Accepted 13.03.2022 ; Avaldatud veebis / Published online 13.03.2022 ; Vastutav autor / Corresponding author: Natalia Georgieva; [email protected] creation of grasslands with the participation of species of local origin, suitable for the climatic conditions of the region and with increased productivity and stability of yield is an important condition for ensuring sustainable or organic feed production. For ecological assessment of meadow species in the semi-mountainous regions of Balkan Mountains according to indicators and parameters related to productivity and stability, an experiment is carried out in the period 2011–2019 in the following variation: Festuca rubra L., Lolium perenne L., Dactylis glomerata L., Arrhenatherum elatius P.B., Festuca arundinacea Schreb., Briza maxima L., Trisetum flavescens L., Agrostis alba L. The experiment is performed by the block method, and the methods of regression, variance and nonparametric analysis are used to assess the stability. According to the values of most of the calculated stability parameters (bi, Si2, λi, σ2i, PP, W2, S⁽³⁾, S⁽⁶⁾, NP⁽¹⁾) Dactilis glomerata shows good ecological stability. Complex evaluation by GGE biplot analysis identifies Festuca rubra L. as a species that favourably combines high productivity with relative stability. Dactilis glomerata and French ryegrass are characte- rized by high stability and yield close to the average for the group. These species are suitable for growing in a wide range of environmental condi- tions

Evaluation of Alfalfa Swards in the Conditions of Middle Balkan Mountains

One of the most effective measures used to enhance natural grasslands in mountain and semi-mountain conditions is the inclusion of species such as alfalfa which is characterized by increased productivity, stability and adaptability. Thus, a comparative study of 3 varieties (‘Pleven 6’, ‘Prista 2’, ‘Multifoliate’) and 2 local populations (LP1, LP2) of alfalfa was conducted in the semi-mountain conditions of the Middle Balkan Mountains. The complex evaluation, comprising productivity and parameters of stability and adaptability, determined the sward of local population LP1, followed by varieties ‘Prista 2’ and ‘Pleven 6’ as the most suitable for cultivation in the Middle Balkan Mountains. They can be used successfully to enhance the composition of natural grasslands. The swards of species, such as birdsfoot trefoil and red clover, which were traditionally grown and typical for the Middle Balkan Mountains, were characterized by lower productivity, stability and adaptability respectively

Techniques for fabrication of temporary dental restorations

Introduction: Temporary restorations are an important part of modern prosthodontic treatment. Temporaries are made nearly exactly like the final restoration while protecting from mechanical, thermal, chemical and biological irritations and improving the patient esthetics and function. They are beneficial in diagnostics and treatment planning. Form, shape, shade and occlusion can be easily evaluated and corrected. Aim: The aim was to evaluate the efficiency of different techniques for fabrication of temporary restorations. Material and methods: Fifteen temporary restorations for single crowns and dental bridges were made with three different techniques direct, indirect and direct–indirect. The direct technique was performed completely in the patient's mouth in one session with putty index after preparation and self-curing bis-acrylic composite resin. The indirect technique was done all in laboratory with wax up of prepared and missing teeth and direct–indirect technique was combination of two techniques but is done before preparation. Advantages and disadvantages were noted during the process of fabrication. Results: The direct technique is the least time consuming procedure, but bis-acrylic resin often gets stuck and locks into undercuts which makes removing the restoration without deformation very difficult. Indirect technique does not consume chair time, but the patient will be longer without restoration making the unprotected prepared teeth more prone to influence of irritations. Direct-indirect technique provides template for the definitive restoration, saves chair time and permits removal of old and immediate replacement with the final restorations. Conclusions: The most efficient technique for fabrication of temporary dental restorations is the direct-indirect technique. Keywords: bis-acrylic composite resin, provisional, putty index, wax-up

New Aspects of Sarcomas of Uterine Corpus—A Brief Narrative Review

Sarcomas of the uterine corpus are rare malignant neoplasms, which are further classified into mesenchymal tumors, and mixed (epithelial plus mesenchymal) tumors. The main issues concerning these neoplasms are the small number of clinical trials, insufficient data from evidence-based medicine, insignificant interest from the pharmaceutical industry, all of which close a vicious circle. The low frequency of these malignancies implies insufficient experience in the diagnosis, hence incomplete surgical and complex treatment. Additionally, the rarity of these sarcomas makes it very difficult to develop clinical practice guidelines. Preoperative diagnosis, neoadjuvant and adjuvant chemoradiation, target and hormone therapies still raise many controversies. Disagreements about the role and type of surgical treatment are also often observed in medical literature. There are still insufficient data about the role of pelvic lymph node dissection and fertility-sparing surgery. Pathologists’ experience is of paramount importance for an accurate diagnosis. Additionally, genetics examinations become part of diagnosis in some sarcomas of the uterine corpus. Some gene mutations observed in uterine sarcomas are associated with different outcomes. Therefore, a development of molecular classification of uterine sarcomas should be considered in the future. In this review, we focus on the epidemiology, pathogenesis, pathology, diagnosis and treatment of the following sarcomas of the uterine corpus: leiomyosarcoma, low- and high-grade endometrial stromal sarcomas, undifferentiated sarcoma and adenosarcoma. Uterine carcinosarcomas are excluded as they represent an epithelial tumor rather than a true sarcoma
