Best Fit of Mixture For Distributed Poisson Multi-Bernoulli Mixture Filtering
Authors: Li Tiancheng , Da Kai
Published: May 2020

The Poisson multi-Bernoulli mixture (PMBM) filter is extended for distributed implementation using a wireless sensor network. At the core of the proposed networking approach, the PMBM posterior is decomposed into two parts corresponding to the undetected and detected targets, respectively. Fusion is motivated to be performed with regard to the latter only which is represented by MBM based on a distributed flooding algorithm for internode communication, which iteratively shares the MBMs between neighbor sensors. Then, a suboptimal “best-fit-ofmixture” principle is followed at each local sensor to find a MBM that best fits the mixture of MBMs aggregated from distinct sensors, leading to an arithmetic average (AA) of these MBMs. We prove the exact closure of the MBM-AA fusion and discuss its sub-optimality and limitations. Simulation demonstrates the effectiveness and limitations of our approach.

The Ancient Routes and New Lycian Inscriptions around Fethiye
Authors: ONUR Fatih , TEKOĞLU Ş. Recai
Published: May 2020

The first part of this contribution contains the results of field surveys made in recent years exploring the ancient road network around Fethiye, including the routes between Pinara, Telmessos, Kalynda, Kadyanda, Araxa and Tlos. According to these results, there are two options for the road between Pinara and Telmessos, one through Kabaağaç and Gökben, one over Babadağ. In the article, the second option is suggested for the road recorded in Monumentum Patarense (MP). While the road between Tlos and Telmessos was at first expected to have passed through today’s Seydikemer, the field surveys identified a better option with a course through Çaltıözü, Bozyer ve Esenköy, crossing over an ancient bridge, only a footing-base of which has survived, in today’s Allıkavak. The ancient route between Telmessos and Kalynda mostly follows the modern road between Fethiye and Dalaman, and the localizations of İnlice/Daidala and Şerefler/Kalynda are discussed again. The road between Kadyanda and Telmessos probably led through Eldirek, and the road between Kadyanda and Araxa passed over the ancient bridge in Atlıdere. The route from Kadyanda to Tlos also passed over this bridge and reached Tlos following a course past Kıncılar, Girmeler and Güneşli. Similarly, the road between Araxa and Tlos followed the same route to the south of Atlıdere Bridge.In the second part of the contribution two new Lycian inscriptions are published. One was found at Asarcık (ancient Aloanda) located ca. 7,5 km to the north of Pinara, and the other on the road between Kadyanda and Araxa. The inscription from Aloanda reflects a religious and funerary content. The type of monument cannot be identified with certainty, because half of the stone is missing. The discussion of the inscription has contributions concerning the vocabulary and morphology of the Lycian language. The find spot of the inscription might have been a religious location, because there are no funerary remains from the Lycian period in the spot. It is less likely that inscription has a funerary character, as there was no rock-cut tomb or early sarcophagus at the find spot, though there are several later funerary monuments of these types nearby. The second inscription has the usual content of Inscribed Lycian rock-cut tombs, of which there are many examples. The tomb’s owner cannot be identified for certain, due to the natural erosion of the inscription surface, but the name may be conjectured as be Armazapimi. The owner built the tomb for himself, his wife, his household and for bis mother’s descendants. Besides the regulations for burials, the inscription ends with a closure stating that anyone who violated the burial regulations, should be considered criminally liable to punishment by several Lycian institutions and divinities.
The Location of Mount Masa on the Northern Border of Hellenistic Lycia
Authors: ONUR Fatih
Published: May 2020

A mount called Masa is mentioned in an inscription from the Letoon (Rousset 2010) and in the foedus (treaty) between Caesar and Lycia (Mitchell 2005), as northern border of Hellenistic Lycia. The inscription from the Letoon, which dates from sometime 160-150 B.C., reads that this mount has been the subject matter of a border conflict between Termessans at Oinoanda and Lycians. This conflict was resolved in a case tried in Kos and parties accepted that Mount Masa should belong to Tloans, but Termessans at Oinoanda could use its wood and grass being prohibited to saw, to harvest or to build on its lands. In the sequel, Lycians had to pay 25 talents of new Rhodian silver plinthophors to Termessans at Oinoanda. Within the frame of this agreement, Mount Masa was demarcated all around and all the details of demarcation fulfilled by a commission was given in the inscription. In addition to 18 boundary marks carved on bedrock, through several geographic descriptions such as roads, ravines, streams, defiles, plateaus and stony places, a comprehensive picture around the mount was presented. However, the location of the mount was nofound, in spite of all the details given in the text. As a result of our 2019 campaign, the ravines are determined on the field and it is understood that Golbanounda, one of two streams mentioned in the inscription, was today’s Hacıosman Deresi, and the second, Endyrenos, was today’s Sarı Dere. Therefore, it has now been understood that Mount Masa was Hacıosman Dağı of today. This contribution contains the details of this discovery.
A Mid-Byzantine Metal Stamp from Bursa Archaeological Museum
Authors: ALTINOLUK Zeynep Sencan
Published: May 2020

This article tries to determine the place and identity of the owner of a metal stamp located in the Bursa Archaeological Museum collection in the Byzantine stamping objects typology. The stamp that we consider in this article is one of the rare examples, in which the inscription specifies the name of the owner as well as the offices and titles he held. The owner of the stamp, dated to approximately 9th –10th centuries, is Iohannes, the imperial protospatharios and epi ton oikeiakon. It is understood from the title protospatharios that Iohannes was a member of the central government and a wealthy aristocrat. The title epi ton oikeiakon, appearing together with Iohannes, may be a title that shows that he is a more privileged individual than other officials and that he may be from the imperial court. On the other hand, we also know of an administrative task under the sekreton of oikeiakon since the last quarter of the 10th century. In light of this, we have the following question: did Iohannes use his stamp for his personal affairs or did he use it in accordance with his responsibilities, which were part of his administrative position of management of imperial properties? In either case, we think that his stamp was stamped on a soft object such as clay and that it may be a brick stamp.

The article notes that domestic agro-formations significantly lag behind the world trends, besides, destructive processes of soil depletion and monopolization of agricultural production are also important. Therefore, the modern stage of their development and development of economic relations on qualitatively new postulates, require from the agro-formations to increase the efficiency and improve the mechanisms and instruments of crisis management by searching and optimizing its organizational and information support. Assessment of modern organizational and information support of crisis management of agro-formations on a qualitatively new multidimensional platform is made, taking into account the specifics of the functioning of agro-formations and their information, organizational, communication and competence capabilities; trends, effectiveness and problems of the development and improvement of organizational and information support of anti-crisis management of agroformations are identified; the influence of key internal and external factors on these processes are studied; priority directions for improving organizational and information support of crisis management of agro-formations are substantiated, including in particular: search for internal opportunities for increasing the level of organizational and information support for crisis management, development and evaluation of a strategic scenarios, budget planning, development of forecasts, plans, schedules of organizational and information support of crisis management, formation and maintenance of an optimum flexibility zone and development of a program of harmonization of organizational and information support of anti crisis management. Implementation of the developed proposals will increase the level of anti-crisis management and provide risk protection of agricultural formations by identifying strengths and weaknesses, taking into account all the challenges and parameters of economic space, fluctuations of the internal environment, unexpected threats, quality processing of objective information flows, innovative and communicative joints.
FORMATION OF CRITERIA AND INDICATORS FOR EVALUATION OF ECOLOGICAL SAFETY LEVEL OF REGIONS OF UKRAINE
Authors: LUTKOVSKA Svitlana
Published: May 2020

This article discusses a methodological approach to the comparative assessment of the regions of the state in terms of environmental safety. A system of indicators characterizing the state of environmental safety in the regional dimension is proposed. It is proved that environmental risk assessment is considered the most promising approach to determining the degree of environmental hazard of the territory. The concept of such assessment in almost all countries of the world and international organizations is regarded as the main mechanism for the development and adoption of management decisions on environmental protection. In the analysis of the existing methodological developments it is established that the environmental hazard assessment is based on several basic approaches. The most commonly used are the indicator based on the system of selected indicators (or indicative method). It is established that the level of environmental safety is quite broad, since it requires consideration of all the components of this process: from the calculation of the level of environmental safety to the assessment of management decisions to overcome environmental risks and prevention. An integral indicator of the level of environmental safety of the regions is proposed, which is based on taking into account the degree of risk of occurrence of environmental losses. The toolkit of existing theoretical and methodological approaches to hazard identification was tested. It has been instrumentally demonstrated that the assessment of the level of environmental and natural-anthropogenic hazards is quite complex as it involves many aspects. Effective comparison of the regions of Ukraine with such a large amount of information is possible only in some socio-economic studies, because because of the variability of different indicators of the level of environmental load it is difficult to determine the impact of which is decisive. An appropriate system of indicators was developed when designing an instrumental framework for determining the level of environmental hazard. It includes indicators of socio-ecological and economic development of regions of Ukraine in dynamics, grouped by function. The system of aggregation of indicators of ecological safety of the region and information matrix of analysis of natural and anthropogenic safety of the region have been developed.
Acetaminophen Test Battery (ATB): A Comprehensive Method to Study Acetaminophen-Induced Acute Liver Injury
Authors: Bhushan Bharat , Apte Udayan
Published: May 2020

Acetaminophen (APAP) overdose is the major cause of acute liver failure (ALF) in the Western world. Extensive research is ongoing to identify the mechanisms of APAP-induced ALF. APAP-induced acute liver injury is also one of the most commonly studied drug-induced liver injury models
in the field of hepatotoxicity. APAP toxicity is triphasic and includes three mechanistically interlinked but temporally distinct phases of initiation, progression, and recovery/regeneration. Despite how commonly it is studied, the methods to study APAP toxicity differ significantly, often
leading to confusing and contradictory data. There are number of reviews on mechanisms of APAP toxicity, but a detailed mechanism-based comprehensive method and list of assays that covers all phases of APAP hepatotoxicity are missing. The goal of this review is to provide a standard protocol
and guidelines to study APAP toxicity in mice including a test battery that can help investigators to comprehensively analyze APAP toxicity in the specific context of their hypothesis. Further, we will identify the major roadblocks and common technical problems that can significantly affect
the results. This acetaminophen test battery (ATB) will be an excellent guide for scientists studying this most common and clinically relevant drug-induced liver injury and will also be helpful as a roadmap for hypothesis development to study novel mechanisms.

Literary works are not merely a bouquet made in a short period of time, but are made with the various components and elements that make a literary work so much appreciated. Bali also in its development also has so many heritages of traditional and modern literary works but which generally become a historical heritage containing so many sacred Hindu religious teachings and still so highly developed in Bali is a rash. The Geguritan as mentioned by experts is a traditional literary heritage in which there are elements of Hindu religion that becomes one of the media in conveying Hindu teachings. One of the most well-known rash is Candrabherawa, composed and composed by I Ketut Ruma which tells the story of the War of Hastinapura with Dewantara due to differences in the implementation of religious teachings. So, of course, there are profound philosophical teachings. The study of the rash of Candrabherawa texts emphasizes the study of the value of Hindu teachings contained in the rash text. From the results of the study, that the text of Candrabherawa is the teaching of Tri Hita Karana, Tri Kaya Parisudha, Catur Marga, and chess clan that can be a reference and guidance in implementing the internalization of Susila value on the strengthening of character education for students by education actors in education institutions.

The article discusses the development of a new method of producing Laetiporus sulphureus (Bull.) Murrill basidiomycete mycelium immobilized on a bacterial cellulose matrix. Mycelium contains biologically active compounds with antimicrobial activity against Gram-positive bacteria, including resistant staphylococcus. The aim of the work was to obtain immobilized mycelium by co-cultivation of L.sulphureus with the producer of bacterial cellulose Gluconacetobacter hansenii. The authors found that when co-culturing the basidial L.sulphureus strain with the bacterial cellulose producing G.hansenii strain, productivity increases by 3.2 times on H5/1 synthetic medium and by 1.9 times on natural Maltax-10 medium (concentration 5%). The resulting immobilized L.sulphureus mycelium has antibacterial properties; its aqueous extracts contain glucans.

Aside from the well-studied conventional actinomycetes such as Streptomyces, the less investigated genera of actinomycetes also represent a promising source of natural products. Genome mining indicated that members of the underexplored genus Pseudosporangium, from which no secondary metabolites have been reported to date, may harbor the biosynthetic machinery for the formation of novel natural products. The strain RD062863, that is available at a public culture collection, was obtained and subjected to metabolite analysis, which resulted in the discovery of a novel cyclopeptide, pseudosporamide (1), along with three new oligomycin-class polyketides, pseudosporamicins A–C (2–4). The unusual structure of compound 1, featured by a biaryl-bond bridging across a tripeptide scaffold, N-acetyl-ʟ-Tyr-ʟ-Pro-ʟ-Trp, was determined by a combination of spectroscopic analyses, chemical derivatization, ECD calculation, and DFT-based theoretical chemical shift calculation, revealing the presence of an (Sa)-axial chirality around the biaryl bond. Compounds 2–4 lacked hydroxylation on the side chain of the spiroacetal rings, which showed clear contrast to other oligomycin congeners and related polyketides with ring-truncation or expansion. The new macrolides 2–4 displayed potent antimicrobial activity against the Gram-positive bacterium Kocuria rhizohpila and the plant pathogenic fungus Glomerella cingulata. All compounds showed moderate cytotoxicity against P388 murine leukemia cells with IC50 values in the micromolar to submicromolar ranges. These results exemplified the validity of phylogeny-focused strain selection combined with biosynthetic gene-directed genome mining for the efficient discovery of new natural products.

Published: May 2020

In this review, it is aimed to focus on the integration of spirituality into family-oriented psychological help processes. To conceptualize the reflection of spirituality on the family system more clearly and to make sense of the spirituality-family relationship, the issue of spirituality was examined in specific processes such as in the relationship between parents and children, between spouses and in the transition process from adolescence to late age. The paradoxical nature of spirituality in family relationships was emphasized. For this purpose, spirituality was discussed both as a source of problems and as a source for solutions in family relations. Spiritually oriented psychological clinical help is an emerging field in Turkey. Seeing that spirituality is such an important issue in family relations and marriage, it is aimed to bring a family-focused approach to the spiritually oriented psychological help process. So, by addressing ethical issues, this review aims to offer a new perspective to field practitioners working with couples and families in clinical practice.

The increasing concentration of populations in urban areas in recent decades has strengthened the interest in – and the importance given to – these zones. Cities have become quite attractive from investors’ point of view because of the wide array of opportunities and growing need for investment in urban areas. Thus, city strategic planning quite often requires an understanding of the determinants that attract investment to urban zones. This study sought to identify the factors that strengthen urban investment based on the knowledge of a panel of experts. Fuzzy cognitive mapping techniques were applied to understand the concepts and decision criteria included in the decision-support model and their cause-and-effect relationships. The results provide insights into which determinants most strongly influence urban investment, namely, infrastructure, supporting services, and political-administrative factors. Diverse scenarios at the intra- and inter-cluster levels were created to clarify the impacts of variable changes on the model developed. The findings were validated by both the expert panel members and the vice-president of the Portuguese Association of Real Estate Developers and Investors. Advantages and limitations of the proposed framework are presented, as well as recommendations for future research.
AN INTEGRATED SCIENTOMETRIC AND SNA APPROACH TO EXPLORE THE CLASSICS IN CEM RESEARCH
Authors: Wu Hengqin , Zhao Zebin , Xue Xiaolong , Shen Geoffrey Qiping , Yang Rebecca Jing , Wang Luqi
Published: May 2020

This study explores the classics that significantly contribute to the research of construction engineering and management (CEM). Previous studies usually simply applied the number of citation to identify the classics, causing some flaws. To overcome the flaws, an advanced approach is developed by integrating scientometric methods (G-index and co-citation analysis) and a social network analysis (SNA) technique (modularity optimization algorithm), thus providing more precise and persuasive results that denote what academic works have made significant inspirations and illuminations on CEM research. This study retrieves 13,273 CEM literature and extracts 336,129 bibliographies from these literature. Based on the G-index, a total of 67 publications are identified as CEM classics. Moreover, this paper measures and maps the structure of the classics by using co-citation analysis and modularity optimization algorithm. The results provide a basic source of academic information representing the foundation of CEM and draw a big picture of CEM to show the underlying associations between the identified classics. This can help researchers recognize the key scientific contributions for improving the academy progress.

Published: May 2020

In this paper, a delayed mathematical model for the P53-Mdm2 network is developed. The P53-Mdm2 network we study is triggered by growth factor instead of DNA damage and the amount of DNA damage is regarded as zero. We study the influences of time delays, growth factor and other important chemical reaction rates on the dynamic behaviors in the system. It is shown that the time delay is a critical factor and its length determines the period, amplitude and stability of the P53 oscillation. Furthermore, as for some important chemical reaction rates, we also obtain some interesting results through numerical simulation. Especially, S (growth factor), k3 (rate constant for Mdm2p dephosphorylation), k10 (basal expression of PTEN) and k14 (Rate constant for PTEN-induced Akt dephosphorylation) could undermine the dynamic behavior of the system in different degree. These findings are expected to understand the mechanisms of action of several carcinogenic and tumor suppressor factors in humans under normal conditions.
Stability analysis and Hopf bifurcation of a fractional order mathematical model with time delay for nutrient-phytoplankton-zooplankton
Authors: Shi Ruiqing ,   School of Mathematics and Computer Science, Shanxi Normal University, Linfen, 041004, China, Ren Jianing , Wang Cuihong
Published: May 2020

In recent years, some researchers paid their attention to the interaction between toxic phytoplankton and zooplankton. Their studies showed that the mechanism of food selection in zooplankton is still immature and when different algae of the same species (toxic and nontoxic) coexist, some zooplankton may not be able to distinguish between toxic and nontoxic algae, and even show a slight preference for toxic strains. Thus, in this article, a fractional order mathematical model with time delay is constructed to describe the interaction of nutrient-phytoplankton-toxic phytoplankton-zooplankton. The main purpose of this paper is to study the influence of fractional order and time delay on the ecosystem. The sufficient conditions for the existence and local stability of each equilibrium are obtained by using fractional order stability theory. By choosing time delay as the bifurcation parameter, we find that Hopf bifurcation occurs when the time delay passes through a sequence of critical values. After that, some numerical simulations are performed to support the analytic results. At last we make some conclusion and point out some possible future work.

Published: May 2020

Background Information about the severity of symptoms during recovery from surgery for lung cancer can be useful in planning and anticipating needs for recovery.

Objectives To describe symptom severity during the first 4 months after thoracotomy for non–small cell lung cancer and factors associated with overall symptom severity at 1 and 4 months.

Methods Ninety-four patients were assessed at 1, 2, and 4 months after thoracotomy by using the Lung Cancer Symptom Scale, Brief Pain Inventory, Schwartz Fatigue Scale, Dyspnea Index, and Center for Epidemiology Studies–Depression Scale (CES-D). Clinically meaningful changes, decrease in the proportion of patients with severe symptoms, and relationships among symptoms were determined. Mixed effects models for repeated measures were used to evaluate changes in severity. Multiple regression models were used to examine correlates of overall symptoms.

Results Mean symptom severity significantly decreased over time for most symptoms. Only disrupted appetite, pain, and dyspnea had clinically meaningful improvement at 4 months. Severe symptoms included fatigue (57%), dyspnea (49%), cough (29%), and pain (20%). Prevalence of depressed mood decreased at 4 months. Most patients (77%) had comorbid conditions. Number of comorbid conditions and CES-D explained 54% of the variance in symptom severity at 1 month; comorbid conditions, male sex, neoadjuvant treatment, and CES-D score explained 50% of the variance at 4 months.

Conclusions Severe symptoms continued 4 months after surgery for some patients, indicating the need for support during recovery, especially for patients with multiple comorbid conditions and depressed mood.

The single-stage configuration of the partial nitritation (PN)–anaerobic ammonium oxidation (AMX) process is preferred due to low pH fluctuation and the low concentration of inhibitory NO2-. The novel core-shell structure integrates ammonia-oxidizing reaction in the outer layer to protect AMX bacteria in the core gel bead from oxygen inhibition and provide NO2-. Here, the initial activity of ammonia-oxidizing bacteria (AOB) in the outer layer was assessed by the specific oxygen uptake rate (OUR). AOB activity was positively correlated with biomass loading in the outer layer. A maximum OUR of 10.5 mg-DO/L∙h was achieved with AOB loading of 0.23 mg-VSS per bead. During AOB enrichment, the NO2- production rate was linearly increased up to 0.65 kg-N/m3-d for 17 days (PVA hydrogel packing ratio=17%). The maximum oxygen penetration depth (OPD) was reduced from 966.7±52.3 μm before enrichment to 333.3±36.4 μm after the AOB enrichment. The liable bacteria were observed within a range of 165 μm of the outer layer using the live and dead cell staining. Based on the OPD and liable cell distribution results, a minimal outer layer thickness of approximately 350 μm was suggested to facilitate a successful PN–AMX process.

Most of the bulbous
plants are known for their medicinal purposes in addition to their ornamental
value. Turkey is one of the home country of many beautiful bulbous plants. In
continuation of our extensive studies on finding new natural cholinesterase inhibitors
from Turkish medicinal plants, Iris
L. species were investigated for their in
vitro cholinesterase inhibitory effects designed to
assess cholinesterase inhibitor activities on both acetylcholinesterase (AChE)
and butyrylcholinesterase (BChE) and antioxidant
capacities with respect to their neuroprotective potential in this study.

The dichloromethane and
methanol extracts prepared from the bulbs of 47 Iris taxa were screened by using modified Ellmann method and the
highest butyrylcholinesterase inhibitory effect was found in the methanol
extract of the bulbs of Iris pseudacorus
L. The dichloromethane sub-extract, which is obtained bioactivity-guided
fractionation of methanol extract of I.
pseudacorus L., was exhibited significant butyrylcholinesterase inhibitory
activity (73.65 ± 2.06 %).
These active sub-extract was subjected to fractionation on column
chromatography and obtained six fractions. Among the fractions, coded as N5 was shown the significant butyrylcholinesterase
inhibitory activity (93.78 ±
1.49 %) compared with
galanthamine (80.02 ± 0.12 %). Fractionation of N5 on flash chromatography the
highest butyrylcholinesterase inhibitory activity of sub-fraction coded as DS-5 was determined as 94.00
± 1.03 %. The responsible compound from the activity of this
sub-fraction was detected as irisolidone glucopyranoside based on its mass data
by using LC-ESI-Q/TOF-MS-MS technique.

Published: May 2020

The study was designed to determine whether cultivation of willow (Salix sp.) energy plantations (WEP) is cost-efficient and to identify the main factors that influence development of such plantations in Lithuania. The economic efficiency of the cultivation of WEP was estimated based on cash flow analysis, discounted cash flow net present value and decomposition analysis methods. The survey of the willow plantation growers identified the motives, incentives, problems and intentions of local willow growers. The study revealed that cultivation of WEP was mostly hindered by economic factors, including low selling price of willow biomass for fuel and high cost of harvesting. Willow cultivation in Lithuania was least hindered by social and ecological factors. The results suggest that European Union (EU) subsidies are currently the main incentive to cultivate willow plantations. However, financial support alone did not guarantee the success of willow biomass harvesting and market access of the final biofuel production. The findings of this study provide information for decision makers on the opportunities and challenges of the development of willow plantations in Lithuania.

Keywords: Salix sp., short-rotation plantations, social and economic factors, economic incentives.

The study aimed to establish the chemical composition of fruit essential oils of M. gale and test their activities against the selected pathogenic bacteria (Staphylococcus aureus, Escherichia coli, Acinetobacter baumannii), yeasts (Candida albicans, C. parapsilosis), fungi (Aspergillus fumigatus, A. flavus) and dermatophytes (Trichophyton rubrum, T. mentagrophytes). Fruit samples from natural (Western Lithuania) and anthropogenic (Eastern Lithuania) M. gale populations were studied separately. Essential oils were isolated from dried fruits by hydrodistillation and analysed by GC/FID and GC/MS methods; enantiomeric composition of α-pinene was established by chiral-phase capillary GC. Minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC/MFC) of essential oils were determined using the broth microdilution method. Plants from the natural population with a humid marine climate accumulated significantly higher amounts of fruit essential oils (3.34±0.05%) than those from the anthropogenic population with a more continental climate (2.71±0.22%). In total, 39 volatiles including α-pinene (23.52–27.17%), 1,8-cineole (17.19–18.84%) and α-phellandrene (9.47–10.03%) as main compounds were identified. Chiral analysis demonstrated that (1S)-(–)-α-pinene prevailed over (1R)-(+)-α-pinene and amounted to 94.09–95.28% of all fraction of this monoterpene. The antimicrobial study in vitro indicated that C. parapsilosis, dermatophytes and Aspergillus fungi were more susceptible to fruit essential oils of M. gale, whereas E. coli and C. albicans were weakly inhibited even at the highest essential oil concentration. The strongest growth-inhibitory and bactericidal effect of sweet gale essential oil was established on S. aureus. This could be attributed to the major essential oil compounds with known antimicrobial activity, such as α-pinene, 1,8-cineole and a-phellandrene.

Edible mycorrhizal fungi can be harvested in the fourth year after establishment of a hybrid aspen plantation in previous agricultural land at hemiboreal conditions. It is important to understand the role of fungi in element cycling at the ecosystem level as well as the amounts of elements, including heavy metals, that are accumulated in fruitbodies of edible fungi in the context of food safety. Therefore we evaluated the carbon and nitrogen stable isotope ratio and content of heavy metals (Cr, Pb, Mn, Ni, Cd, Cu and Zn) in Leccinum aurantiacum (Bull.) Gray in a juvenile hybrid aspen (Populus tremuloides Michx. × Populus tremula L.) plantation in agricultural land initially fertilised with biogas production residues (digestate), sewage sludge and wood ash, which are potential sources of pollution of heavy metals. The research site was established in the spring of 2011, but the natural occurrence of fruitbodies of L. aurantiacum was observed in 2014. The mean isotopic data for fruitbodies of L. aurantiacum, collected in the 2014–2018 monitoring period, ranged between -27.4 and -24.5‰ for δ13C and between 7.8 and 10.1‰ for δ15N. The mean content of investigated heavy metals in fruitbodies of L. aurantiacum were up to 129 mg kg-1 for Zn, up to 99 mg kg-1 for Cu, up to 30 mg kg-1 for Mn, up to 1.5 mg kg-1 for Ni, up to 1.7 mg kg-1 for Cd, up to 1.1 mg kg-1 for Cr and up to 0.6 mg kg-1 for Pb. We concluded that the application of digestate, sewage sludge and wood ash as fertilisers to improve soil quality in hybrid aspen plantations in agricultural land did not result in increased heavy metal accumulation in fruitbodies of L. aurantiacum, but N isotopic compositions were altered (15N-enriched) for a period of up to five years after application of the organic fertilizers (digestate and sewage sludge).
