Authors: Bjekić Radmila , Jelača Maja Strugar , Marić Slobodan 
Published: May 2020

Abstract
The aim of the paper is to investigate if there is any correlation between active leadership style and organizational innovativeness in the case of middle and large companies that operate on the territory of the Republic of Serbia. For this research authors have used Multifactor Leadership Questionnaire (MLQ) on the sample of 159 organizations that have more than 50 employees. Respondents were managers. For data analysis Hierarchical Multiple Regression and Spearman’s correlation was used. Results of analysis show that there is a statistically significant positive relationship between active leadership style and organizational innovativeness in companies in the Republic of Serbia. Available literature and results of previous surveys pointed out all benefits of this leadership style and in this paper results of research show that active leadership style is one of the crucial factors which encourage organizational innovativeness. Due to its positive influence on creating innovative atmosphere and growth of innovativeness, managers should pay more attention to active leadership style and implement it.

Published: May 2020

Abstract
The Agro-innovation Broker (AIB) concept was introduced by the European Commission solely to increase the vast spread of innovative solutions in Agriculture. The concept can be perceived as an intermediary between the demand and supply of agricultural research and extension services. This paper’s results are derived from the international research work that aims to develop a training curriculum in the field of agricultural innovation services with effective materials to boost capacity building actions in Central and Eastern European Countries (CEE). Based on consultations with stakeholders, the Hungarian situation analysis allowed comparison with other CEE countries and the expansion of an AIB vocational training curriculum. It helps to better understand the needs of agricultural innovation services through a clear view of advisors’ competences. Our results suggest that apart from the similar knowledge requirements and skills of AIBs across CEE countries, country-specific expectations and needs should be addressed in AIB training.
Differential expression and functional analysis of two short-chain alcohol dehydrogenases/reductases in Hedychium coronarium
Authors: Chen Hua , Yue Yuechong , Yu Rangcai , Fan Yanping 
Published: May 2020

Abstract
In this study, the full cDNA sequences of HcADH2 and HcADH3 were cloned from Hedychium coronarium. The amino acid sequences encoded by them contained three most conserved motifs of short-chain alcohol dehydrogenase (ADH), namely NAD+ binding domain, TGxxx[AG]xG and active site YxxxK. The highest similarity between two genes and ADH from other plants was 70%. Phylogenetic analysis showed that they belonged to a member of the short-chain dehydrogenases/reductases 110C subfamily, but they were distinctly clustered in different clades. Real-time polymerase chain reaction analyses showed that HcADH2 was specifically expressed in bract, and it was expressed higher in no-scented Hedychium forrestii than other Hedychium species, but was undetectable in Hedychium coccineum. HcADH3 was expressed higher in the lateral petal of the flower than in other vegetative organs, and it was expressed the most in H. coronarium that is the most scented among Hedychium species, and its expression levels peaked at the half opening stage. HcADH2 and HcADH3 had almost no significant expression in leaves, but HcADH2 was expressed in response to external stimuli. The mechanical injury and methyl jasmonate (MeJA) treatment could induce expression of HcADH2 in leaves, whereas HcADH3 could have an induced expression only by MeJA. The recombinant HcADH3 protein, but not HcADH2, expressed in Escherichia coli-catalysed conversion of geraniol into citral. It was speculated that HcADH3 had an induced expression in vegetative organ of H. coronarium and took part in monoterpenoid biosynthesis in H. coronarium flowers, but the role of HcADH2 is relevant only for defensive reactions.
Applying abundance/biomass comparison curves to small mammals: a weak tool for detect urbanization-related stress in the assemblages?
Authors: di Bagno Ermellina , Battisti Corrado , Zullo Francesco , Amori Giovanni 
Published: May 2020

Abstract
Urbanization is a form of pervasive human-induced disturbance. We tested the effectiveness of Abundance/Biomass Comparisons (ABC) as an approach in detecting stress due to landscape urbanization in large small mammal assemblages obtained from pellets of Barn Owl (Tyto alba; Strigiformes). We compared three assemblages sampled in not urbanized contexts (agro-mosaic landscapes) with three assemblages preyed in highly urbanized contexts. In all assemblages, the role of strictly synanthropic species (in our case: rodents) emerged since almost all of total biomass was assigned to these species: indeed, everywhere (both in agro-mosaic and urbanized sites) species of low trophic level (i.e. omnivorous/herbivorous rodents) significantly prevail in biomass when compared to insectivorous species (i.e. shrews, Soricomorpha) linked to less anthropized habitats. This biomass dominance in rodent species is highlighted by the data on evenness, showing lower values in biomass when compared to abundance. This pattern did not match with the classic assumption expressed by the ABC model (i.e., species with higher biomass are typical of undisturbed assemblage) and could be wrongly interpreted. Our study evidenced as ABC approach is a not reliable tool to detect the effect of urbanization as landscape disturbance acting on small mammal assemblages. Therefore we suggest that the ABC assumptions are not universal but limited only to assemblages where high body mass species coincide to species of a higher trophic level.
Beech bark disease in Slovakia related to fungi of the genus Nectria S.l. and the anatomy of necrotised bark and wood: a brief review
Authors: Račko Vladimír , Mihál Ivan , Mišíková Oľga 
Published: May 2020

Abstract
This short review summarises the history and current knowledge regarding beech bark disease (BBD) in Slovakia. Moreover, the results of ongoing long-term disease monitoring are summarised. The article also provides a list of the 29 Nectria s.l. species found to date in Slovakia, complete with information about their occurrence on host tree species. Above all, we highlight the need for histopathological research on beech tissues attacked by different Nectria spp. Notably, neither the defensive response mechanisms of host cellular tissues at the anatomical and biochemical levels nor the strategy of decomposition by different pathogens have been explored in beech.

Published: May 2020

Abstract

Objectives
The general objective of this research was to see if academic achievement significantly relates with social anxiety of high school students. There were other specific and auxiliary objectives also. One among these was to gather prevalence data of social anxiety among adolescents of Kathmandu.

Method
A survey was conducted among 696 high school students of Kathmandu to see if academic achievement was associated with their social phobia. Convenient sample from a high school was used. Social Phobia Inventory (SPIN), a self-report test, was used to measure social anxiety disorder of adolescent students. Some demographic data were also collected. Data were organized in MS Excel and analysed in SPSS.

Results
The prevalence of ‘very severe’ social phobia among boys was 2.01% and girls had that of 1.71%. One-way ANOVA showed that academic achievement did not have a relationship with social phobia, F (2, 613) = 1.74, p > 0.05.

Conclusions
Academic achievement was not associated with social phobia among students of a high school in Kathmandu. Boys have more prevalence of severe forms of social anxiety than girls when they are in adolescence.

Authors: Lü Y. , Chen X. , Xue W.F. , Zhang W.D. 
Published: May 2020

Summary
Analysis of soil nematode feeding groups and functional guilds were used as a valuable tool to detect heavy metal pollution. Effects of cadmium (Cd) at 5 mg/kg, mercury (Hg) at 20mg/kg, combined Cd and Hg at 5+20mg/kg on the nematode communities were studied after three months application. Nematodes were collected from soil in rhizosphere of Morning glories (Pharhiris nil) which were applied as heavy metal accumulators and were grown in the experimental pots. Both single and combined heavy metals had marked effects on the nematode abundance, life-history strategies and feeding type composition. Bacteriovores and c-p 2 group were found to be the most abundant trophic group and functional guild, respectively. Acrobeloides and Pratylenchus were the most two abundant genera, decreasing number of them was responsible for the significant difference between control and polluted treatments. Cd-5 and Cd-Hg 5+20 presented lower values of nematode diversity index (H’) and evenness index (J’) than Hg-20. The combination of Cd and Hg showed lower nematode trophic diversity (TD), in comparison with single Cd or Hg. Conversely, heavy metals addition exhibited no pronounced effect on Maturity index (MI), structural index (SI) and enrichment index (EI). Our results demonstrate that genera composition is a better indicator to short-term heavy metal effects than some common indicator indices and emphasize that deeper assemblage analyses are needed for a correct interpretation of short-term disturbance on soil nematodes.

SummaryRegarding geographical distribution and clinical relevance, the most common canine geohelminths areToxocara canis, ancylostomatids, andTrichuris vulpis. Canine intestinal parasites from the soil and sand present an important potential serious human health hazard, especially for the children preschool and school – age. This paper aimed to establish the degree of contamination of soil and sand with zoonotic parasites from the canine feces and the degree of risk they could pose for human health in public places and playgrounds in the city of Niš. Our parasitological study involved 200 soil samples and 50 sand samples from the public parks in the city of Niš in southeastern Serbia (43°19′15″N, 21°53′45″ E). From several locations, about 100 g of soil and sand was collected based on the bioclimatic indices. Parasitological diagnosis was performed using conventional qualitative and quantitative coprological methods, abiding by the recommendations about the diagnosis of parasitic diseases. In 38 – 46 % of soil samples and 40 % of sand samples seven species of endoparasites were diagnosed. In the samples of soil, a medium and high degree of contamination with the ascaridT. canis(14 – 22 %) was detected, as well as a low and medium degree of contamination with ancylostomatids (4 – 12 %), and in the samples of sand, a variable degree of contamination with the helminthsT. canis(26 %) andA. alata(16 %) was found. A statistically significant difference was found in the contamination withA. alataeggs between the samples of sand and samples of soil. The studied public surfaces represent the reservoir of zoonotic parasites, which is a public health problem requiring a synergistic action of several factors to be successfully resolved, i.e. the implementation of prevention, surveillance, and control measures.

Authors: Dygas Robert 
Published: May 2020

Abstract
This article concerns the determinants of foreign direct investment (FDI) outflow from India to Poland with some insights to other European countries. This topic strongly relates to globalization of foreign trade and especially new economic initiatives between European Union (EU) and India, which was one of the first countries to develop trade relations with EU. According to CEIC data – Financial Data and Economic Indicators, India’s FDI outflow increased slightly to 1.4 billion USD in September 2019 in comparison with 996.5 million USD in September 2018, but it is still below the average of 1.8 billion USD for a period of 2007–2019.
Available at: https://www.ceicdata.com/en/india/foreign-direct-investment-outflow/foreign-direct-investment-outflow (accessed October 19, 2019).
Very limited number of the scientific research can be found in European literature about India’s FDI outflow to EU countries in period of 2004–2019. Indian economists made some research on that topic. Professor J. Ramachandran (listed among the Best Management Thinkers for the year 2015, the first Bain Fellow in India) from Indian Institute of Management Bangalore in 2004 and Professor Jaya Prakesh Pradhan from Central University of Gujarat in 2008 explored the evolution in Indian outward FDI, referring to a shift in the pattern of overseas expansion and basis of competitiveness of Indian companies. The main goal of this article is to explain what really triggers Indian investors to go to Poland and what kind of businesses they form. Some examples of the Indian-based companies are mentioned to support the analysis. The author of this article also researched on different governmental bilateral trade agreements and initiatives, trying to find any direct impacts of that on the India FDI outflow to Poland and other EU countries. He used empirical method of the analysis based on accessible data for period 2004–2019 and literature in that topic and also direct interviews with private Indian investors who made decision to start and run their business in Poland or other EU countries. The main conclusion is that Poland the leader of Visegrad Group is an interesting investment for India and India can be for Poland a counterpart investment partner to China.
What’s New in the 2019 Esc Guidelines on Chronic Coronary Syndromes?
Authors: Ilieșiu Adriana 
Published: May 2020

Abstract
The European Guidelines for Diagnosis and Treatment of Chronic Coronary Syndromes (CCS) were published in 2019 with a different title than the previous 2013 Guidelines that referred to “chronic stable coronary heart disease”, underlining the dynamic nature of the atherosclerotic process. The main changes in these guidelines refer to the most frequent clinical presentations of CCS, to the assessment of the pretest probability of atherosclerotic coronary heart disease with the recommendation to include cardiovascular risk factors and other factors, as well as the choice of invasive anatomical and/or functional diagnostic tests, invasive and/or non-invasive, depending on the probability of the existence of the disease.
Regarding the treatment, these guidelines underline the importance of a healthy lifestyle and the modalities for the implementation and the strategy of anti-ischemic drug treatment, antithrombotic therapy being more widely addressed. Recommendations for myocardial revascularization on top of drug treatment for symptoms control and for improving prognosis are less restrictive in these guidelines. The recommendations of the CCS guidelines are harmonized with the recommendations of the other European guidelines, especially with those on diabetes, prediabetes and cardiovascular diseases which were also published in 2019.
A Clinical Approach of Renal Involvement in Granulomatosis with Polyangiitis
Authors: Stoian Marilena , Indrei Lucia , Stoica Victor 
Published: May 2020

Abstract
Granulomatosis with polyangiitis (GPA, Wegener’s granulomatosis) is one of the antineutrophil cytoplasmic antibody (ANCA) - associated small vessel vasculitis, involving various organs such as nasal septum, sinuses, upper respiratory tract, lungs, and kidneys. GPA is pathologically characterized by necrotizing granulomatous inflammation. ANCA-associated small vessel vasculitis represent a major challenge in hospital admissions; therefore, early and accurate diagnosis with aggressive treatment is essential to improve the disease outcome.
Renal involvement of granulomatosis with polyangiitis is characterized morphologically by extensive crescent formation (extracapillary proliferation in Bowman’s space), and clinically by crescentic or rapidly progressive glomerulonephritis that causes hematuria, erythrocyte casts, and proteinuria with progressive loss of renal function. The diagnosis of granulomatosis with polyangiitis is established most securely by biopsy specimens showing the triad of vasculitis, granulomata, and large areas of necrosis (known as geographic necrosis) admitted with acute and chronic inflammatory cells. Usually, renal involvement is severe and is the leading cause of mortality. The combination of high-dose corticosteroids and cyclophosphamide is the mainstay of treatment for vasculitis and disease resistance to this combination is rare.
Catastrophic Caustic Ingestion: A Case Report
Authors: Bouchard Kerri L 
Published: May 2020

Abstract

Introduction
The majority of oral ingestion of caustic material by adults is intentional, and the aftermath varies widely with potentially fatal results. Injuries range from superficial burns of facial and oropharyngeal structures to extensive necrosis of the gastrointestinal tract. Management focuses on the identification of the ingested substance and prompt treatment and supportive care of the multiple complications stemming from the ingestion. Complications following caustic ingestion include both immediate and long term.

Case presentation
A fifty-seven-year-old man presented following intentional ingestion of drain cleaner. The patient was intubated and underwent emergent esophagogastroduodenoscopy [EGD], which revealed extensive damage to his oesophagus and stomach. He survived his initial injury but had a prolonged hospital course and ultimately died after developing tracheoesophageal and bronchooesophageal fistulas which were too extensive for surgical repair.

Conclusion
The sequelae of caustic ingestion can be minor or severe, both immediate and delayed. Despite appropriate prompt management and supportive care, patients may die as a result of the initial injury or subsequent complications.
Some remarks on enhanced total internal reflection

Published: May 2020

Abstract
The regime of total internal reflection of plane wave on the boundary between a lossless dielectrics and the lossy, or gainy, medium is analysed. It is shown that in order to achieve enhanced total internal reflection (TIR), ie magnitude of the reflection factor larger than one, the existence of the second boundary, virtually maybe infinitely far away, is inevitable. Some contradictory results published in literature are discussed.
Deriving the exchange times for a model of trap-assisted tunnelling
Authors: Racko Juraj , Mikolášek Miroslav , Kadlečíková Magdaléna , Benko Peter , Chvála Aleš 
Published: May 2020

Abstract
The work presents a physical model of trap-assisted tunnelling that allows assessing the impact of traps upon the total current through metal/semiconductor heterostructures. The model is based on expressing the occupation probability of the trapping centres by electrons in terms of thermal and tunnelling capture and emission times, commonly referred to as exchange times. The occupation probabilities calculated in this way are then used to evaluate the generation-recombination rates occurring in the continuity equations.

Abstract
The article analyzes available methods for preventing acoustic resonance of high pressure lamps. A new method is proposed, the main idea of which is the filing of a high-voltage lamp modulated by a pseudo-random signal. An analysis of the spectral characteristics of the signal entering the lamp is made, the mathematical modeling of the set of a “discharge lamp - prototype of the device” - is implemented, which implements the proposed control method of the lamp. The results of simulation and oscillograms, taken from the prototype, which confirms the results of theoretical research, are presented.
Properties of a modelled call centre
Authors: Baronak Ivan , Hartmann Matej , Polacek Robert 
Published: May 2020

Abstract
To detect the number of agents needed to serve customers, it is necessary to consider the call centre as a mass service system. Then it is possible to asses the convenient number of agents according to the probability of the system receiving a request and the time in which the request is serviced by employing a Markov chain and the Erlang model. In an archetypal call centre, the incoming calls are added to a waiting queue and subsequently they are assisted by an agent. In case all agents are occupied, the customer has to wait in the queue until one of the agents becomes available. It is, therefore, important to compromise on the number of agents and the time the customers spend waiting in the queue. The result should be that there are enough agents in the call centre to serve the customers in the time required. This article focuses on solving this problem.
Power saving technique based on traffic channels reallocation in GSM mobile network
Authors: Kosjer Vladimir , Mitić Dragan , Lebl Aleksandar , Matić Vladimir , Markov Žarko 
Published: May 2020

Abstract
A mobile users’ network with power control on traffic channels, as it is GSM, is considered in this paper. It is analyzed the influence of busy channels reallocation on the necessary emission power. The main principle in reallocation is that users who need greatest power for their connections take traffic channels of the first carrier where power is always maximum. It is assessed that reallocation process is not more complicate than the simplest handover processes. It is proved that this method may be used to decrease emission power of carriers after the second one. Power saving depends on number of carriers, environmental propagation coefficient and users’ density distribution in the cell. The results are verified by originally developed simulation program.
