It is seen that in the Bay of Bengal or in the Gulf, most of the time the atmospheric phenomena, like, cyclone, hurricane etc. move towards right to its motion. To study such occurrences; we have considered fluid dynamics of ocean coupled with atmospheric motion. In the present study we have considered the eye of the cyclonic system that consist of fluid dynamical source and fluid dynamical sink at a small distance apart, and thus, constitute the fluid dynamical doublet of the object system. Then the fluid dynamical doublet of the object system and its image system has been considered with respect to a firm wall (here the sea shore). The fluid dynamical equation of complex potential with respect to the object system, the image system and the stream velocity have been undertaken. The complex potential of the object doublet, image doublet and the stream velocity have been considered. The velocity vector, consequently the pressure has been retrieve with the help of Bernoulli’s equation of fluid motion. Then the minimum /maximum pressure on the wall that is on the sea shore has been calculated analytically. Thus, it is found that on the basis of some prevailing conditions existing wind and energy the cyclone or hurricane move towards the sea coast or to the right of its motion.

Authors: Tadele Biruk , Quezon Emer T
Published: January 2022

Engineers have been using modified binders to improve the quality of flexible pavements. The use of waste material is one of the solutions taken in this direction. It is for this ground that the studies emphasis on the evaluation of waste engine oil as a modifier for asphalt binder as a pavement material. In the study uses four samples extracted from 80/100 penetration grade bitumen. From four sample first sample was checked for weather requirements of asphalt binder meet or not and the three were modified with different content of engine oil (3,6 and 9%). The behaviors of both unmodified and modified binder were checked for rheological properties. Dynamic shear rheometer (DSR) was used to determine high temperature performance grade (PG) and multiple stress creep recovery tests to determine rutting resistance properties of the binder. PG analysis indicates that both aged and un-aged 3% and 6% modified binder have similar higher PG grade with the unmodified one and 9% modified to have lower PG vale. Jnr3.2 value of modified asphalt binder is lower than unmodified binder indicating that modification had improved the rutting resistance and design traffic load (ESALS). The study shows that it is possible to use waste engine oil-modified binder as a pavement material.
SEEKING THE CODE OF THE GROUND
Authors: Simpson Brian
Published: January 2022

This paper explores three topics that constantly challenge geotechnical engineers: deformation, water and safety.More speciically, these topics involve understanding and predicting deformation, designing safely when water pressure is dominant, and, more generally, trying to manage the many uncertainties we face in a rational manner that can be agreed and communicated to others. Evolving understanding of the secrets coded in the ground have led to developments in computercodes for ground deformation and codes of practice for geotechnical design.Using the author’s own career as a background, the paper considers the development of ideas related to these topics over thepast forty years. This is not a monotonic process: ideas and understand from one project may lie dormant for some years andthen be developed when a fresh need arises at a later stage. Equally important are the colleagues and mentors with whom problems can be addressed and ideas discussed; some outstanding individuals will be acknowledged.

Published: January 2022

Central Sulawesi, precisely in the city of Palu, is one of the areas that frequently occurs in earthquakes and has high seismicity. The regional geology of the Palu area and its surroundings is dominated by quarterly deposits consisting of fluivatil and alluvium deposits. These natural conditions have several potentials that are detrimental, including the potential for liquidity. (Widyaningrum, 2012).

Liquidation is an event that occurs when a soil becomes saturated or loses its ability to support the mass above it because the land changes form into heavy water or becomes liquid. Lack of further knowledge about the faction by the surrounding community causes a lack of vigilance in dealing with the faction.

The things that people need to know about potentially liquefaction soils are data on soil moisture, changes in underground temperature, and vibrations that are felt underground when earthquakes occur shortly after liquefaction using a device in the form of an arduino nano-based data recorder. The Design of Arduino Nano Based Likuefaction Data Recording Tool can be used to record and record data on lycufaction disaster events. And is used to make it easier to analyze the potential occurrence of liquefaction in certain regions by utilizing the sensor to measure soil temperature, soil moisture, and vibrations that occur in the soil.

Published: January 2022

The COVID-19 pandemic situation has hampered wound care services. Apart from contact restrictions, patient and family anxiety to visit hospitals and health workers having diabetic wound care skills are still inadequate. Only 1 unit of First Level Health Facility (FKTP) has succeeded in developing a diabetic wound care polyclinic; thus, the percentage of diabetic wound sufferers who receive standard services is only 1 percent. This study aims to determine predictors of graduate performance after wound care training with blended learning methods in Jakarta Province in 2021. Descriptive quantitative method using a cross-sectional approach and primary data were collected using structured questionnaire survey technique. The study was carried out from August to September 2021. The population was all 44 graduates of wound care training with the blended learning method. The result shows that the correlation value (r) between age and performance score was 0.43 with a P-value of 0.007. It means that there is a statistically significant relationship between age and the graduate performance score. There is also a significant relationship between motivation and performance scores, with the correlation value (r) between motivation scores and performance scores of 0.37, P-value of 0.020. The dominant factor that affects graduate performance is motivation, with a P-value of 0.02. The magnitude of the variation that affects the dependent variable is 0.129, meaning that the motivation variable can explain 12-13 percent of the variation in the graduate performance score.
Fiber Optic Network Technology of Communication of Specialists via Mental Neurointerfaces
Authors: Bryndin Evgeniy
Published: January 2022

Resonance communication of specialists can be carried out at a distance in real time in dialogue mode through a mental neurointerface with two-way communication. Mental neurointerface on the principles of magnetic resonance tomography captures a hologram of brain activity of the internal speech of the inductor specialist and transmits it to the mental neurointerface of the recipient's interlocutor through ultra-sensitive multi section nano resonators waveguides. The mental neurointerface of the recipient's interlocutor perceives the transmitted hologram of the brain activity of internal speech and resonates its internal speech to it. An interlocutor of the recipient with equivalent semantic memory in a resonant way makes sense of the internal speech of the inductor specialist. He forms the response with internal speech and transmits it to the interlocutor with his mental neurointerface through nano resonators in the form of holograms of the brain activity of internal speech. Interlocutors, as specialists in one subject area, have a similar semantic memory. Semantic memories are considered similar if they correspond to the principle of gold section according to a professional thesaurus. Specialists and interlocutors must learn a professional thesaurus before starting a dialogue through mental neurointerfaces. Thus, the problem of transmitting and reading thoughts at a distance using high technology is solved, taking into account the psychological aspects of the interlocutors. The development of mental neurointerfaces and ultra-sensitive multi section nano waveguide resonators for transmitting holograms of internal speech brain activity is just beginning. The use of resonant communication by mental neurointerfaces through nano waveguides resonators waveguides is currently very relevant in many areas of life activity.

Published: January 2022

Many governmental agencies and private companies of different countries are now rushing into space around Earth in hope to provide smart communication, industrial, security, and defense solutions. This often involves massive launches of cheap small satellites which are also contributing to the growth of space debris. The current paper discusses how the developed high-level system philosophy and model can effectively organize distributed space-based systems on different stages of their development and growth. The briefed Spatial Grasp Technology, based on parallel pattern-matching of distributed environments with high-level recursive mobile code, can effectively provide any networking protocols and important applications of large satellite constellations, especially those on Low Earth Orbits. The paper contains examples of technology-based solutions for establishing basic communications between satellites, starting from their initial, often chaotic, launches and distributing and collecting data in the growing constellations with even unstable and rapidly changing connections between satellites. It describes how to organize and register networking topologies in case of predictable distances between satellites, and how the fixed networking structures can help in solving complex problems. The latter including those related to the new Space Development Agency multiple-satellite defense-oriented architecture and allowing for effective integration of its continuous earth custody observation and cooperative missile tracking and elimination layers, based on self-spreading mobile intelligence. Earlier versions of the technology, described in many papers, six books including, were prototyped and used in different countries, with the current one quickly implementable too, even in university-based environments.

Celem niniejszego artykułu jest odniesienie polskiej klasyfikacji stylizacji językowej przeprowadzonej
przez Dubisza (1996: 17-20) do pewnych ustaleń z zakresu badań nad stylistyką języka japońskiego.
Wspomniany wyżej polski podział stylizacji językowych zastosowano w celu opisu stylistyki języka
mówionego, który został utrwalony w tekście jako zapis rozmów oraz dialogów postaci literackich
i komiksowych. Dwie spośród pięciu klas stylizacji wydzielonych przez Dubisza zostały wykorzystane
w celu rozpatrzenia wyników badań nad stylistyką japońskich gatunków multimodalnych (Kinsui,
Yamakido 2015). Japońskie stylizacje językowe rozważono pod kątem wpływu cech indywidualnych
postaci na style językowe oraz multimodalnego charakteru komiksu i powieści ilustrowanej. Podjęcie tej
próby umożliwiło wydzielenie pewnych innowacji w obrębie istniejącej polskiej klasyfikacji stylizacji
językowej.
Polish classification of the varieties and types of speech stylization as a tool for addressing selected areas of Japanese stylistics
Summary: The aim of this study is to apply the classification of speech stylization proposed by Dubisz (1996:
17-20) to some findings reported on in studies on Japanese stylistics. The classification was utilized to
describe the stylistics of spoken language, transcribed into text as a record of the utterances of fictional
characters in Japanese literature and comic books. Two out of five classes of stylizations defined by Dubisz
were used as reference points for reviewing the results of studies on the stylistics of Japanese multimodal
genres (Kinsui, Yamakido 2015). Japanese speech stylizations were evaluated with regard to
the impact of individual traits of characters on their speech styles and to the multimodal nature of genres such as comic book and illustrated book. This attempt has led to the proposal of some innovations in the Polish classification of speech stylizations.
Vitamin B9 in Dark Green Vegetables: Deficiency Disorders, Bio-Availability, and Fortification Issues
Authors: Singh Jagdish
Published: January 2022

Folic acid is a B complex water-soluble vitamin that is essential to humans, and its deficiency can cause problems including neural tube defects as well as heart-related diseases. An important feature of such vitamins is that they are generally not synthesized by mammalian cells and therefore must be supplied in sufficient amounts in the diet. Folate is a generic term for compounds, possessing vitamin activity similar to that of pteroylglutamic acid, and is the form of the vitamin, which is naturally present in foods. The main dietary sources of folic acid are dark green and leafy vegetables such as spinach, asparagus, romaine lettuce, broccoli, bok choy, turnip green, beet, dried or fresh beans, and peas. The amount of folate that is absorbed and utilized physiologically varies among different food sources and different chemical forms of the vitamin. About 85% of folic acid is estimated to be bioavailable; however, the bioavailability of food folate is estimated at about 50% of folic acid. Several national health authorities have introduced mandatory food fortification with synthetic folic acid, which is considered a convenient fortificant, being cost efficient in production, more stable than natural food folate, and superior in terms of bioavailability and bio-efficacy. Presently, many countries affected by diseases associated with a lack of folic acid have made it mandatory to supplement foods with the vitamin. Considering the need, several analytical procedures were standardized to determine the presence of folic acid in different food matrices. The reported methods are simple, selective, robust, and reproducible and can be used in routine analyses.

Published: January 2022

This chapter aims to provide a complete knowledge over the primary intraocular lymphoma (PIOL) and a correct clinical approach towards this rare condition, to avoid delays in diagnosis, which is considered the most important prognostic factor. A PIOL arises with no specific symptoms and could mimic both inflammatory and non-inflammatory ocular conditions. Also known as reticulum cell sarcoma in the past, PIOL is an ocular malignant condition, with a strong bond with primary central system lymphoma (PCNSL). This linkage is underlined by the fact that approximately 30% of the patients with PIOL have also PCNSL at presentation, while 45–90% will develop PCSNL in the following months. A correct diagnosis is currently achieved by the means of many different techniques: cytology, flow cytometry, immunohistochemistry, molecular analysis, and cytokines assay. Treatment of this condition has been completely revolutionized with the introduction of monoclonal antibodies directed against specific proteins present on the surface of lymphomatous cells.
Experimental and Computational Modeling of Microemulsion Phase Behavior
Authors: Yee Hon Vai , B.M. Saaid Ismail
Published: January 2022

The phase behavior of microemulsions formed in a surfactant-brine-oil system for a chemical Enhanced Oil Recovery (EOR) application is complex and depends on a range of parameters. Phase behavior indicates a surfactant solubilization. Phase behavior tests are simple but time-consuming especially when it involves a wide range of surfactant choices at various concentrations. An efficient and insightful microemulsion formulation via computational simulation can complement phase behavior laboratory test. Computational simulation can predict various surfactant properties, including microemulsion phase behavior. Microemulsion phase behavior can be predicted predominantly using Quantitative Structure-Property Relationship (QSPR) model. QSPR models are empirical and limited to simple pure oil system. Its application domain is limited due to the model cannot be extrapolated beyond reference condition. Meanwhile, there are theoretical models based on physical chemistry of microemulsion that can predict microemulsion phase behavior. These models use microemulsion surface tension and torque concepts as well as with solution of bending rigidity of microemulsion interface with relation to surface solubilization and interface energy.

Authors: Tian Yichao , Yang Yongwei
Published: January 2022

Identifying the mutual relationship between ecosystem services in southwest Guangxi can jointly optimize a variety of services to avoid damaging others while improving one service, which is of great significance for promoting the sustainable management of regional ecosystem, guiding the rational development of natural resources and improving human well-being. Based on remote sensing data, land use data, meteorological data and DEM data, with the support of Carnegie-Ames-Stanford Approach (CASA) model, Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model and Revised Universal Soil Loss Equation (RUSLE) model, this paper studies the changing characteristics of typical ecosystem services in southwest Guangxi and explores the mutual relationship between different ecosystem services. The results showed that the mean change trend of the whole vegetation net primary productivity (NPP) has been increasing in the study area over the past 19 years. In the past 19 years, water conservation in southwest Guangxi has shown a fluctuating upward trend, with the growth rate of water conservation quality 255.88 mm/hm−2·a−1. During the study period, the range of soil retention variation to the total of 65.38–96.88 t/hm−2·a−1 increased 22.73 t/hm−2·a−1, with a mean of 79.19 t/hm−2·a−1. Vegetation NPP in the study area is synergistic with soil conservation and water conservation, and soil conservation with water conservation as well.

Published: January 2022

Forests across the globe have been exploited for resouces, and over the years the demand has increased, and forests are rather exploited instead of sustainable use. Focussed research on vegetation and forerst dynamics is necessary to preserve biodiversity and functioning of forests for sustanence of human life on Earth.This article emphasis that the India has a long history of traditional knowledge on forest and plants, and explorations from 17th century on forests and provided subsequent scientific approach on classification of forests. This also explains the developments of quantitative approach on the understanding of vegetation and forest diversity. Four case studies viz., Mudumalai, Sholayar, Uppangala, Kakachi permanent plots in the forests of Western Ghats has been explained in detail about their sampling methods with a note on the results of forest monitoring. In the case of deciduous forests, the population of plant species showed considerable fluctuations but basal area has been steadily increasing over time, and this is reflecting carbon sequestration. In Sholayar, a total of 25390 individuals of 106 woody species was recorded for < 1 cm diameter at breast height in the first census of the 10 ha plot in the tropical evergreen forest. In Uppangala, 1) a 27- year long investigation revealed that residual impact of logging in the evergreen forests and such forests would take more time to resemble unlogged forests in terms of composition and structure; 2) across a similar temporal scale, the unlogged plots trees < 30 cm gbh showed a more or less similar trend in mortality (an average of 0.8% year-1) and recruitment (1%). The Kakachi plot study revealed that 1) endemic species showed least change in stem density and basal area whereas widely distributed species showed greater change in both; 2) The overall recruitment of trees was 0.86 % per year and mortality 0.56% per year resulting in an annual turnover of 0.71% ; 3) majority of the gap species had high levels of recruitment and mortality resulting in a high turnover.Such studies can be used as early warning system to understand how the response of individual plants, species and forests with the climatic variability. In conclusion, the necessity of implementation of national level projects, the way forward of two such studies: 1) impact of climate change on Indian forests through Indian Council of Forestry Research and Education (ICFRE) colloborations and 2) Indian long term ecological observatorion, including the sampling protocols of such studies. This will be the first of its kind in India to address climate change issues at national and international level and helps to trace footprints of climate change impacts through vegetation and also reveals to what extent our forests are resilient to changes in the climate.

Published: January 2022

In this era the requirement for energy is enhancing, therefore, many energy resources are developed among them the emerging third-generation dye-sensitized solar cell is one of the environment-friendly solar cell-based technology. Generally, dye-sensitized solar cells consist of a nanomaterial-based photoanode, dye molecules as an absorber, electrolyte, and counter electrode. In the case of indoor application, this solar cell works easily so this is the characteristics of a dye-sensitized solar cell. Moreover, the outdoor performance of DSSC degrades on exposure to sunlight. Exposure to sunlight increases the temperature of the internal component of DSSC and consequently degradation in device performance. Long-term stability is obtained by the choice of such material where degradation takes place slowly and plastic covers are also coated over DSSC to prevent degradation. The solar response of DSSC towards dye was also mentioned, the higher the percentage of EQE higher the efficiency of the device. In this chapter, the authors discuss the introduction of a solar cell, the working principle of DSSC, and the available research background for outdoor performance and long-term stability with a solar response of device i.e. EQE or IPCE.

Published: January 2022

This paper points out the importance of assessing the cultural, historical and ecosystem values of protected areas using the protected areas benefit assessment tool (PA-BAT). This method has so far been applied in seven Dinaric Arc countries (Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, North Macedonia, Albania and Serbia) in south-eastern Europe, as well as other countries in the world (Colombia, Turkey, Myanmar, USA and Ethiopia), with the aim of helping to gather information on the values and benefits of individual protected areas in relation to ecosystem services, using a participatory approach. Using the case study of Djerdap National Park (in the Republic of Serbia), the results of applying the PA-BAT method are given, that is, the results of assessing 22 ecosystem values with special reference to cultural and historical values as one of the ecosystem services of this protected area, as well as the results of previously conducted assessments of the ecosystem values of this area. The aim of this paper is to contribute to a better understanding and promotion of applying the concept of ecosystem services in the preservation of cultural, historical and ecosystem values by applying PA-BAT evaluation methods.
Nullity as a prerequisite of contract conversion
Authors: Mijanović Dražen
Published: January 2022

Although it has been legally recognized since 1978, the conversion (lat. Conversio - conversion) of contracts is one of the institutes to which no deserved attention has been paid in domestic theory. In textbooks that cover the general part of civil law, and those used for teaching the law of obligations, this institute is, with certain exceptions, presented rather briefly - usually, beside the legal definition, we find only the field of application and examples of conversion. We were unable to find monographs on the subject of conversion. On the other hand, in foreign literature, mostly German and Italian, we find a large number of monographs on the topic of conversion. The subject of this paper is one part of the norm that prescribes the conversion of a contract, and that is the nullity of a contract, which is provided as a precondition for the application of the institute. The scope of application of conversion seems to be precisely and clearly defined, especially having in mind the text and the place of the norm within the Law Contracts and Torts, and in this paper we will see if that is actually the case. In the search for the answer, we also used the comparative legal method. The area of application of conversion was considered - and we did not limit ourselves only to null and void contracts, but we considered the possibility of its application to non-existent, null and void, voidable contracts, then to partially null and void contracts, but also to valid contracts. Within null and void contracts, special attention is paid to those illegal and immoral, and within non-existent ones - to a simulated contract.
The relationship between lis pendens and exclusive international jurisdiction based on a choice of court agreement in the law of the Hague Conference and Bosnia and Herzegovina
Authors: Poljić Adis
Published: January 2022

The subject of the paper refers to the analysis of the exercise of the will of the contracting parties regarding the jurisdiction of the court in the law of the Hague Conference and Bosnia and Herzegovina. The exercise of the will of the contracting parties may be limited by the institute of lis pendens, which makes it impossible to conduct two proceedings between the same parties simultaneously for the same claim based on the same facts, giving priority to the first one, regardless of agreed-upon international jurisdiction. By agreeing on the jurisdiction, the contracting parties decide which court will resolve their dispute, which is extremely important for them. Based on the analysis of the Hague Convention on Choice of Court Agreements, it is concluded that preference is given to proceedings before the chosen court, with certain exceptions when the agreement of the parties will not apply. The law of Bosnia and Herzegovina applies the rules of lis pendens which may prevent the application of the agreement of the parties.
On the shortcomings of the plea agreement
Authors: Milošević Dragana
Published: January 2022

The plea agreement is an institute of criminal procedure law that was introduced into the Criminal Procedure Code in 2011 as one of three agreements that can be concluded by the public prosecutor and the defendant. The author points out the shortcomings of the agreement in terms of the absence of a prescribed penalty as a condition for concluding an agreement, determining the sentence without presenting evidence, with an emphasis on extenuating and aggravating circumstances, and provides suggestions on how to prevent or eliminate problems that could occur in praxis by applying valid legal solutions. In order to obtain answers to some of the above questions, a research questionnaire was created on the basis of which the author collected data from a court and public prosecutor's office in order to prove the presented hypotheses. From the methodological aspect, in addition to documentary analysis, the comparative and historical method, prediction strategy and the medium-scale method were used for the purpose of the research.

Published: January 2022

Family and work are the most important aspects in an individual"s life, and the primary goal is to find a balance between these two. Given the characteristics of working in the hotel industry, employees in this industry very often face a conflict between family and work. This study aims to measure the impact of socio-demographic characteristics (gender, age, education and marital status) on work-family conflict (WFC) and turnover intentions (TI). On the sample of 1.100 employees in different hotel facilities by applying t -test and analysis of variance ANOVA, it was found that tested socio-demographic characteristics are not significant indicators of experiencing WFC, but age and marital status are proven to be significant determinants of turnover intentions. Results obtained in this study can help managers to understand antecedents and consequences of experiencing work-family conflict and to undertake activities to reduce these conflicts and turnover intentions of employees.
Management of continental saline ecosystems in the Republic of Serbia: Are these ecosystems suitable for nature-based tourism?
Authors: Luković Milica , Šilc Urban
Published: January 2022

Continental saline habitats represent unique, authentic and rare ecosystems. These ecosystems are typically distributed in arid and semi-arid regions; however, they are also found in inland areas in temperate climate zones. Usually, the general public is not familiar with this particular type of ecosystem. In order to present saline habitats to tourists, a broadly applied method of ecosystem suitability assessment (ESI-ecosystem suitability index) was used and adjusted to the purposes of this research. The research aims to estimate the nature-based tourism potentials of selected sites. Thus, six representative halophytic habitats distributed along the geographic gradient, from the Pannonian Plain to the south of Serbia, were chosen. In terms of each site, seven indicators (e.g., flora and vegetation, bird fauna, landscape, protection status, accessibility, and ecotourism facilities), important for nature-based tourism, were analyzed. The results show that the Pannonian saline habitats have greater opportunities for development of this type of tourism in almost all categories compared to southern sites.

The COVID-19 virus pandemic appeared to be a low-probability, high-impact event that has caused significant disruptions in supply chains worldwide. The hotel industry has been one of the most severely affected, with all participants in the supply chain suffering from the crisis. This paper aims to analyze if, and to what extent, hotels in the Republic of Serbia have faced difficulties in supply chain management (SCM) due to the COVID-19 virus pandemic, with special reference to the difficulties in introducing information and communications technologies (ICTs) for SCM. Empirical research was conducted in May, 2021 involving managers from 40 hotel companies categorised as 4-and 5-star. The study results reveal that majority of hotel companies have experienced difficulties in SCM and implementation of ICTs for SCM due to the pandemic, while the intensity of difficulties is not found to be correlated with hotel size, category and affiliation.

Authors: Perčić Karolina , Spasić Nada
Published: January 2022

The subject of the paper is the consumer behaviour of Millennials and Generation Z as travellers in organising their travel. Through empirical research, conducted with online questionnaire in May 2021, the paper focuses on the way the above-mentioned generations in Serbia have organized travel (through a travel agency or on their own) before and during the COVID-19 pandemic, as well as the choice of accommodation during the pandemic, and the respondents' opinions on travel with COVID-19 passports. The aim of this paper is to discover the preferences and opinions of travellers when organizing travel under the new circumstances, as well as examining whether there are differences in the behaviour of Millennials and Generation Z as travellers before and during the pandemic, in order to provide significant information for the marketing decision making of tourism and hospitality organisations. Almost a quarter of the world's population is made up of Millennials, who, along with Generation Z, make up the current and future force that contributes the most to the income generation. Members of this population in Serbia are less and less opting for the services of travel agencies, especially during the pandemic, while the number of passengers of these generations who organize self-directed travel is on the increase. Quantitative statistical methods-descriptive statistics (frequency distribution) and comparative statistics (Pearson ch2-test) were used for analysis of the obtained research results.

This paper presents the plant genetic resources maintained by the Center of Excellence for Legumes of the Institute of Field and Vegetable Crops, National Institute of the Republic of Serbia. The genetic resources of legumes (soybean, alfalfa, red clover, pea and vetch) are an invaluable source material and a rich source of genetic divergence for the development of varieties adapted to specific agricultural and environmental conditions. Soybean is the most important of all cultivated legumes and occupies the largest area under cultivation. The alfalfa collection consists of over 800 genotypes with different agronomic traits and dormancy values. The novel alfalfa breeding concept - breeding for yield per se, based on natural heterosis in the development of half hybrids - was introduced in the late 20th and early 21st centuries. The Center of Excellence for Legumes has 757 soybean genotypes, 655 red clover genotypes, about 730 pea genotypes and 495 vetch genotypes. The development of the winter pea variety for grain (NS Mraz), the first of its kind in South-Eastern Europe, was significant for science.

This paper deals with the methods of natural healing that were practiced already in the 19th century by Swiss natural healer Arnold Rikli as a part of healing offer in Bled, Slovenia. The paper starts with the introduction of Rikli as a natural healer and his healing methods, based on hydrotherapy, heliotherapy, climate therapy and healthy diet. His healing methods were based on strengthening the immune system in a natural way. The paper takes an ethnographic approach based on in-depth analysis of the literature and online resources and fieldwork in Bled using the technique of partially structured interviews with the employees in tourist industry. The paper identifies the potential for the inclusion of Riklis natural healing methods in the modern tourist offer as the basis for creating Covid-adapted programmes and a source of survival for the existing wellness centres and other tourism providers in Bled.
