PURPOSE: the purpose of the study was to analyse the influence of different NaCl concentrations on germination and seedling parameters in three rice cultivars belong to species Oriza sativa L. - Osmanchik 97, Kameo and Luna. METHODS: six NaCl salt concentrations were studied (low concentrations: 25 mM and 50 mM NaCl solutions, medium concentrations: 75 mM and 100 mM NaCl solutions and high concentrations: 125 mM and 150 mM NaCl solutions). Germination data and seedling parameters were recorded. RESULTS: The application of salt concentrations between 25 and 150 had no significant effect on seed germination, while suppressive effect on seedling characteristics. At 150 mM NaCl mean germination time ranged from 2.10 days (for Osmanchik 97) to 3.15 days (for Kameo), mean ShL ranged from 3.65 cm for Kameo to 5.33 cm for Osmanchik 97. With increasing concentrations of NaCl vigor index decreased from 2043 for Osmanchik 97 (control) to 1050.24 for the variety Kameo. CONCLUSION: At 150 mM NaCl concentrations, the studied varieties showed very high salt tolerance to seed germination, high salt tolerance to root growth and medium salt tolerance to shoot growth. Тhe study confirmed that rice cultivars at the stage of seed germination are more tolerant to salinity than at the early seedling stage.
目的:研究不同NaCl浓度对Oriza sativa L. 3个水稻品种- Osmanchik 97、Kameo和Luna发芽和幼苗参数的影响。方法:研究6种NaCl盐浓度(低浓度:25 mM和50 mM NaCl溶液，中浓度:75 mM和100 mM NaCl溶液，高浓度:125 mM和150 mM NaCl溶液)。记录发芽数据和幼苗参数。结果:施用25 ~ 150浓度的盐对种子萌发无显著影响，但对幼苗特性有抑制作用。在150 mM NaCl处理下，平均萌发时间为2.10 ~ 3.15 d，平均ShL为3.65 ~ 5.33 cm。随着NaCl浓度的增加，活力指数从对照的2043下降到1050.24。结论:在150 mM NaCl浓度下，所研究品种对种子萌发具有极高的耐盐性，对根系生长具有较高的耐盐性，对茎部生长具有中等的耐盐性。Тhe研究证实，种子萌发阶段的水稻品种比苗期早期的水稻品种更耐盐。

The accumulated amount of information about human morphology is enormous and this leads to a suitable environment for a new qualitative leap in the understanding of the human body. Material and Methods: Scientific publications available online. The methodology is: heuristic formation of the goal, systematic thinking, holistic approach, and comparison between the up-to-date embryology facts with the modern theories in physics and the traditional holistic philosophies of China. Aim: The purpose of this report is to validate STHB from an embryological point of view. Results: The embryonic period provides clear evidence for the spiral theory of the human body, demonstrating the center, its boundary, the equal importance of negative and positive structures, the primordial scale and the transition to different sub-scales, its short duration, and the clear transition to the next period of life. Conclusion: Most axioms of the STHB could be validated by human embryo development. As a disadvantage, one can consider the weak anthropological demonstration of the typical human characteristics that distinguish him from the animal world.

The article presents results and analysis of data from a national survey conducted among teachers, regarding the science literacy of Bulgarian students. The conducted international studies PISSA and TIMSS show that the results of Bulgarian students are below the average for the study. In the field of natural sciences, the most significant decrease was observed, with the average score of Bulgarian students according to PISSA data falling by 22 points in the study conducted in 2018, compared to 2015. The research presented in this article was conducted through an online questionnaire with 15 questions of different types. 105 teachers participated in the study. The results show that teachers use different methods to build science literacy in students. Teachers share that they are partially or not familiar with the results of the PISSA and TIMSS international studies conducted in our country, in the years 2015 and 2019. They need additional methodical help and literature for acquiring further knowledge and skills for improving science literacy among students.

The present study aims to determine the efficiency of a given industry in the regions of the country by identifying the sectors for which comparative advantages can be derived. This study will focus on the dynamic changes in the territorial and sectoral structure of employment, as those sectors that have the potential for development have been determined through defined criteria. The localization coefficient is used to determine the industries with a high degree of concentration and the effect of national and regional trends on the industry structure is established through a “shift-share” analysis of employment. As a result of the analysis, the need to increase the efficiency of the industries, for which the region has comparative advantages, is highlighted, as this is a prerequisite for increasing its competitiveness. The impact on the industries identified in the development in the direction of stimulation would have a favorable effect on the growth of the economy in the region, respectively on the economy of the country as a whole.

The primary sector has been completely reshaped by the assignation of specific functions to farmers over the last 25 years, since legislators noted the importance of quality food productions to the rural and agro-industrial sectors and formally established rural and agri-food districts as legal entities. Agro-towns and rural districts in Italy, despite their peculiarities, represent an element of continuity in the path of social and economic development of the Italian countryside, contrasting the risk of marginalisation in rural areas through a propulsive growth of social capital and human interactions. The main purpose of this research was to assess the development of rural districts in some Italian regions as a consequence of the diffusion of agro-towns. The method of investigation has been a theoretical approach aimed at assessing the diffusion of the rural districts from 2016 to 2019 and by a comparison among Italian regions using some maps. Drawing some final remarks, agro-towns represent a fundamental pillar for the growth of the rural district in Italy due to their specificities in terms of social capital and local development, which are able to give a special connotation to the surrounding rural territory in a process of economic growth. In conclusion, the model of the rural district represents a spearhead for the countryside, emphasising all the peculiarities of rural areas where the impact of agro-towns has been significant in the past. The main consequence has been a transition of agro-towns from being degraded structures, where the incidence of agricultural underemployment was high, to structures where, despite the diffusion of large estates, there is an advanced social and economic development able to create a cohesive space that works to contrast the marginalisation of the Italian countryside.

It is important for beef cattle breeding to ensure responsible animal husbandry and food production, which entails economic, social and environmental implications. Furthermore, it is essential to guarantee a genetic resource prepared for the different challenges of our times. This study includes information about beef cattle breeding in Bulgaria, and describes the characteristics of the Galloway breed. The numerical data presented in the study are based on the available information included in various references in the Agrostatistics database of the Ministry of Agriculture and Foods, agrarian reports of the same ministry and the Executive Agency for Selection and Reproduction in Animal Breeding (EASRAB). The Galloway breed is one of the oldest and purest of local cattle breeds. They are known for their resilience and can subsist on the scarcest of lands, which is important under the conditions of current climatic and other challenges. Regarding the Genetic Reserve and the Gen Bank, registered by the EASRAB, the available information shows that there is no registered reserve and genetic bank for the Galloway breed in Bulgaria. This requires further studies and proposals for the inclusion of the Galloway breed in the selection and reproduction aimed at the development of sustainable beef cattle farming.

The purpose of the present study was to investigate the histologic and micrometric study of the proventriculus and gizzard of the wild bronze turkey (Meleagris gallopavo). Thirty clinically healthy Bronze turkeys (15 females and 15 males) were used for the study. Twelve tissue samples (six from the proventriculus and six from gizzard) from the corresponding age group were used to prepare histological slides. The preparations were stained with hematoxylin (Erlich) - eosin and Masson’s trichrome. The wall of the proventriculus was composed of four layers. They were tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa. Mucosa had many grooves and plicae with simple columnar epithelium. The proventricular submucosa had compound tubuloalveolar glands which took the greatest part of the wall. The gizzard had tunica mucosa, tunica muscularis and tunica serosa. Compound tubular glands were found in the mucosa. On the mucosal surface was observed a thick keratinized layer, which was produced by the glands. In lamina propria mucosae were found compound tubular glands which opened on the mucosal surface by a short neck. The glands in the grooves were more branched, compared to those localized in the folds. Lamina muscularis mucosae was not found.

Objective: By "foreign bodies" should be understood all objects of external or internal origin that may block partially or completely the lumen of some parts of the respiratory system - nasal passages, larynx, trachea, bronchi. Most often foreign bodies in the respiratory tract occur in children under 4 y.о. They represent 80% of cases. Twice as often in boys. In 65% of cases, foreign bodies are food particles. 50% of them are accounted for: peanuts, walnuts, hazelnuts, chickpeas, and sunflower seeds. Methods: The author demonstrates a case of an unusual foreign body in the upper airway in a 2 y.o. child. He presented at ENT Clinic in the University Hospital of Stara Zagora with sudden paroxysms of coughing and difficulty swallowing, which started during hugging his mom. Results: It was performed an X-ray examination and visualized an object with a metal consistency that corresponded to a safety pin. Immediately was realized pediatric and anesthesiologist consultation and the patient was taken to the operating theatre and under general anesthesia, the foreign body was removed. Conclusions: Aspiration of foreign bodies in the airways is accompanied by dramatic moments and often fatal and it is still a serious problem in Otorhinolaryngological and pediatric practice. This imposes the serious need to strengthen preventive actions in this direction by increasing the consumer culture of the people.

Mucosal melanomas are rare malignant neoplastic disease, that originates from melanocytes in mucosal tissue. It is a tumor mass of the nasal cavity or paranasal sinuses and most commonly originates from the nasal septum, nasal turbinates, or lateral wall and rarely occurs in the floor and roof of the nasal cavity. Most people with nasal cavity melanomas present with atypical nasal symptoms. The authors demonstrate the clinical manifestation and the therapeutic process of a 65 y.o. patient with malignant melanoma in the sino-nasal region.

Visceral leishmaniasis (VL) is one of the important parasitic diseases caused by the obligate intracellular protozoan parasite of Leishmania donovani complex. The disease is associated with severe morbidity and is fatal if left untreated. Human VL is rare in Bulgaria, but local cases are registered annually in the country. Diagnosis of the disease is based on clinical and epidemiological data and the different laboratory methods for ethiological diagnosis. Isolation of the causative agent through cultural methods, allows to make an extremely accurate diagnosis, but require time and cost of materials. Cryopreservation of isolated parasites allows their keeping for a long time and recovery in need of subsequent immunological and molecular analyzes. The described and optimized cryopreservation method of Leishmania species promastigotes in laboratory conditions is easily feasible and reliable and can be used for long-term storage of these parasites without changing their viability and biological characteristics.

Diagnosis of the disease is based on clinical and epidemiological data and the different laboratory methods for ethiological diagnosis. Isolation of the causative agent through cultural methods, allows to make an extremely accurate diagnosis, but require time and cost of materials. Cryopreservation of isolated parasites allows their keeping for a long time and recovery in need of subsequent immunological and molecular analyzes. The described and optimized cryopreservation method of Leishmania species promastigotes in laboratory conditions is easily feasible and reliable and can be used for long-term storage of these parasites without changing their viability and biological characteristics.","PeriodicalId":30048,"journal":{"name":"Trakia Journal of Sciences","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67464376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
