Abstract Some microorganisms identified in cave ecosystems have been reported to play a permanent and significant role for maintaininglife in such environments. Human entrance into caves can induce some changes on cave physic-ochemical parameters which altimately affects the living organisms. In this regard, for the first time, Morca Cave was explored to evaluate the impacts that human activities may have on the microbial diversity of the cave in a limited period of time. During this expedition at a depth of 1040 m, a camp was established for four days. Before the installation and at the end of the camp, sediments and surface samples were taken from different points of the camp area and the area around it. Sequencing of 16s rRNA of each sample was performed using the next generation sequencing method. The profile of the microbial diversity before the camping reaveled that Thermoplasmata dominated the archaea group and Gamma- and Alpha-proteobacteria were the most dominant bacterial group. After the camp, a decrease in the microbial diversity especially the previously mentioned classes strains is observed at the most of the sampled areas. The results also showed that Bacilli strains significantly increased after the camp and increase of Bacteroidia strains is observed at the most active sampled areas. This present study therefore highlights how microbial diversity inside a closed cave can respond to the human activities within a short period. Furthermore, it may constitute a solid basis to support efforts targeted at improving technics for cave management and expedition for the conservation of cave nature.

AbstractBackground: The world tourism industry is subject to big changes. A number of tourists traveling steadily grows, resulting in turnover and income. The destinations, that tourists are attracted, to are numerous, and there are also newcomers who arrive to a certain destination for the first time. Nowadays, even some very distant places are on the travellers’ bucket lists. What is more, tourists are looking for authenticity, in terms of which the concept of ethno village proves to be such an example.Purpose: The purpose of this paper is to investigate how this kind of tourism is regulated in Slovenia and Bosnia and Herzegovina. The emphasis will be on the study of specific ethno villages.Methods: Regarding the article, desk analysis will be done. The data were gathered from the world web, from the World Tourism Organisation’s data and from the data gathered from Slovenian and Bosnian national statistical office as well. The Excel was used for the analyses. Two examples of an ethno village are also described.Results: The ethno village as a part of rural tourism offers great opportunities for new work posts but capacities should be used to a greater extent and the problem of seasonality should also be overcome. All the key aims of rural development must be defined by the following strategy: the development of sustainable and efficient agricultural sector, the living standard of the population who lives from agriculture, creation of social and economic conditions in the rural regions; all of it within the National strategy of the rural development.Conclusions: Tourism industry is being developing as a part of modern touristic migration. There are more and more visitors coming overseas or coming from more remote places. They stay for a short period of time and they have different expectations as before.

Beginning in the early 1970s, Jewish and Muslim feminists, tackled “oral law”—Mishna and Talmud, in Judaism, and the parallel Hadith and Fiqh in Islam, and several analogous methodologies were devised. A parallel case study of maintenance and rebellion of wives —mezonoteha, moredet al ba?ala; nafaqa al-mar?a and nush?z—in classical Jewish and Islamic oral law demonstrates similarities in content and discourse. Differences between the two, however, were found in the application of oral law to daily life, as reflected in “responsa”—piskei halacha and fatwas. In modern times, as the state became more involved in regulating maintenance and disobedience, and Jewish law was backed for the first time in history by a state, state policy and implementation were influenced by the political system and socioeconomic circumstances of the country. Despite their similar origin in oral law, maintenance and rebellion have divergent relevance to modern Jews and Muslims.

Diesel acts as a main energy source to complement human activities in Antarctica. However, the increased expedition in Antarctica has threatened the environment as well as its living organisms. While more efforts on the use of renewable energy are being done, most activities in Antarctica still depend heavily on the use of diesel. Diesel contaminants in their natural state are known to be persistent, complex and toxic. The low temperature in Antarctica worsens these issues, making pollutants more significantly toxic to their environment and indigenous organisms. A bibliometric analysis had demonstrated a gradual increase in the number of studies on the microbial hydrocarbon remediation in Antarctica over the year. It was also found that these studies were dominated by those that used bacteria as remediating agents, whereas very little focus was given on fungi and microalgae. This review presents a summary of the collective and past understanding to the current findings of Antarctic microbial enzymatic degradation of hydrocarbons as well as its genotypic adaptation to the extreme low temperature.

The purpose of the study is to investigate the concern developments of first-time distance education instructors using the concerns-based adoption model (CBAM). This study used stages of concern (SoC), a component of CBAM, as its theoretical framework. A descriptive case study was implemented, which focused on the adaptation processes of nine instructors lecturing for the first time via distance education. The instructors attended a two-day training, which was designed based on their initial concerns. Then instructors implemented their courses for four weeks via distance education. While the informational and personal stages (self-concerns) decreased compared to the initial findings, the consequence stage increased in intensity. However, self-concerns remained predominant in the process despite the reduction in self-concerns and increase in the consequence stage. Based on the findings, the implications for distance education and recommendations for addressing the instructors’ concerns are discussed. Recommendations for alleviating the concerns of first-time distance education instructors include: the provision of ongoing concern-based interventions that incorporate technological, pedagogical, and content knowledge; providing working examples related to distance education from which instructors can learn vicariously; and encouraging collaboration among instructors.

Increasing industrial competitiveness has led to an increased global interest in condition monitoring. In this sector, rotating machinery plays an important role, where the bearing is one of the most critical components. Many vibration-based signal treatments are already being used to identify features associated with bearing faults. The information embedded in such features are employed in the construction of health indicators, which allow for evaluation of the current operating status of the machine. In this work, the use of contour maps to represent the diagnosis map of a bearing, used as a health map, is presented for the first time. The results show that the proposed method is promising, allowing for the satisfactory detection and evaluation of the severity of bearing damage. In this initial stage of the research, our results suggest that this method can improve the classification of bearing faults and, therefore, optimise maintenance processes.

This paper compares, for the first time, nutrient levels and chlorophyll a measured in a set of seasonal lakes with those reported for permanent lakes in the literature. Twenty-two turloughs (karstic seasonal lakes) in western Ireland were sampled monthly from the onset of flooding (October) until they dried out (6 to 9 months). The turloughs showed similar levels of nutrients and chlorophyll a to those reported for Irish and international lakes. Chlorophyll a peaked between November and February in the majority of turloughs, sometimes with values higher than those measured in mesotrophic lakes in summer. A significant log-linear regression was found between total phosphorus and chlorophyll a, which suggests P limitation of algal biomass in the majority of the turloughs. The regression characteristics were not significantly different than those described in similar studies of permanent lakes. Patterns in seasonal variation of nutrients are also presented, their underlying causes being discussed in relation to their transport within catchments. Our results show that despite being predominantly winter phenomena, turloughs can be as productive as permanent lakes.

Objectives. Psoriasis makes a relative contraindication for lithium treatment which can exacerbate its symptoms or induce it itself. On the other hand, lithium exerts immuno-modulatory activity. Case study. In this paper, a case of a female patient is presented. The patient has been treated since 2012 for bipolar affective illness (bipolar disorder – BD) and psori­asis, which occurred for the first time during a depress­ive episode. Despite intensive pharmacological treatment, both as inpatient and outpatient, a satisfactory improvement of affective illness has not been obtained. After the introduction of lithium, a remission of BD was achieved as well as a reduction of psoriatic changes, which have been maintained until now (2021). Conclusion. The remission of Bipolar Disorder (BD) on lithium can suggest that the patient belongs to the group of the so-called excellent lithium responders. In the presen­ted case remission of psoriasis was observed during lithium treatment. This case report must be treated with caution because remission could be spontaneous and the patient needs further observation.
