Abstract
In the present work, with an aim of developing new useful materials, carbon dot-graphene oxide-zinc oxide (CGZ) nanocomplexes were synthesized by the wet chemical method. Structure, morphology and chemical composition of prepared GCZ nanoparticles were determined by carrying out X-ray diffraction, scanning electron microscopy, Fourier transform infrared and energy dispersive X-ray absorption spectral measurements. The strong absorption band observed in the UV region for the prepared samples can be attributed to the band edge absorption. The dielectric parameters, viz. dielectric constant (∈r), dielectric loss (tanδ) and AC electrical conductivity (σ AC) were determined at various temperatures in the range of 30 °C to 150 °C at two different frequencies (100 Hz and 1 kHz). DC conductivity (σDC) measurement was also carried out at various temperatures in the range of 30 °C to 150 °C. In addition, the enhanced photocatalytic activity of CGZ has been explained and the mechanism elucidating the excellent performance of CGZ has been proposed.

Abstract
Water deficit or drought stress is one of the most significant abiotic stresses that induce reduction in plant growth and crops yield. Calcium chloride has been shown to ameliorate the adverse effects of drought stress on many plants. Therefore, this study aimed to investigate the role of calcium chloride in drought resistance and its effect on some physiological characteristics in sesame. Calcium is essential for good growth and structure of plants. In sesame (Sesamum indicum L.), the foliar application of calcium chloride (C1=0 (control), C2=5, C3=10 and C4=15 mM concentration) significantly affected on grain yield under drought stress (W1= 7 (control, no drought stress-plants irrigation at a 7-day interval), W2= 12 (severe drought and plants irrigation at a 12- day interval) and W3= 17 (the most severe drought and plants irrigation at a 17-day interval). Drought stress reduced grain yield and 1000 seed weight, but these were enhanced by foliar application of calcium chloride when drought levels increased from W1 to W3. Although the increasing calcium chloride concentration reduced the content of photosynthesis pigments in leaves, the drought treatment until W2 increased the content of photosynthetic pigments (chlorophyll “a” and carotenoids) in leaves. The foliar application of calcium chloride increased the seed weight in plant, the number of capsules per plant, plant height, and the concentration of potassium and phosphorus in leaves and seeds. The greatest amount of potassium in leaves and seeds were measured under the W1C3 treatment. Sesame plants under W3C3 and W2C3 had the highest amount of phosphorus in leaves and seeds, respectively. Overall, although drought stress reduced the growth and grain yield in sesame, the foliar application of calcium chloride at the concentration of 10 mM, prevented the drought-stressed sesame plants from damage by improving their physiological parameters.

Published: January 2020

Abstract
In this mini-review we present insight to the non-nuclear transposable elements and in silico analysis of miniature inverted transposable elements (MITEs) in the grapevine mitochondrial genome. Here we report the identification of 17 truncated sequences in grapevine (Vitis vinifera L.) mitochondrial genome which expectedly belongs to the four ancient transposon families (hAT, Tc1Mariner, Mutator and PIF/Harbinger). Some sequences with a high rate of homology in chloroplast and nuclear genomes were also identified. Thus, it suggests the intercellular gene transfer between these three organelles. These partial sequences showed a high level of similitude with full MITE sequences, and they were found in their inner region, supporting their MITE origin. Further analysis revealed these sequences in other life kingdoms (including eubacteria and archaea), which indicates their ancient origin. Further research showed that 13 out of the 17 sequences are conserved domains of the genes where they are located, suggesting their contribution to gene evolution. Therefore, we suppose that more studies of nature, origin and functional meaning of these sequences and their fusion with genes are necessary. In the light of our observations it will be useful for further studies of V. vinifera genome organizing and systematics, as well as for other species.
Canopy-Dwelling Arthropod Response to Rynaxypyr and Lambda-Cyhalothrin Treatments in Maize
Authors: Keszthelyi S. , Pónya Z. 
Published: January 2020

Abstract
The technology of grain corn production has recently been continuously changing due to spreading of insecticidal in-crop treatments in Europe. The aim of these interventions is to prevent damage caused by serious lepidopterous pests in maize. We carried out in-maize field experiments using two different active ingredients of insecticides in four consecutive years (2014–2017). A field experiment was conducted to compare the effect of applications of rynaxypyr (ANT) and rynaxypyr + lambda-cyhalothrin (PYR) on the canopy-dwelling arthropod community in commercial maize grain acreage. The effects of both ANT and PYR treatments against Ostrinia nubilalis Hübner (Lep.: Crambidae) were tested through four-year field experiments. The quantitative and qualitative assemblages of the perished arthropods and diversity alterations measured by canopy netting and grounded tarpaulins greatly differed in the different insecticide treatments. A significant number of dead arthropods was recorded after PYR treatment. Populations of other natural enemies (Coccinellidae, Chrysopidae, etc.) and endangered species (Calomobius filum, Rossi) were also negatively affected. The arthropod community of the examined maize plots was drastically altered by sprayings, which, among other factors, may account for the mass appearance of the other non-target pest organisms (Aphidae: Rhopalosiphum spp., Miridae: Trygonotylus spp.).

Published: January 2020

AbstractFood market has changed dramatically over past decades. Whereas in the past consumers faced problems with food availability and quantity, today they are more concerned with its qualitative side. Milk, Slovak traditional foodstuff, is now experiencing the declining consumer interest. Regarding this, the main aim of the article is to examine the importance and influence of quality attributes on Slovak consumers when purchasing milk. For accomplishing this, a quantitative consumer survey was arranged. Its results showed that to the group of top five most important quality attributes belonged healthiness, freshness, sensory appeals, processing and fat; and a presence of at least two dependencies in relation to age, gender, income and education individually was confirmed. This creates a valuable basis for the value concept development, segmentation, targeting and positioning projection, product strategy modification and innovation and segmentation and marketing mix strategy creation.

Published: January 2020

Abstract
Predictive modeling is the key fundamental method to study passengers’ behavior in transportation research. One of the limited studied topic is modeling of public transport usage frequency, which can be used to estimate present and future demand and users’ trend toward public transport services. The artificial intelligence and machine learning methods are promising to be better substitute to statistical techniques. No doubt, traditionally been used econometrics models are better for causal relationship studies among variables, but they made rigid assumptions and unable to recognize the pattern in data. This paper aims to build a predictive model to solve passengers’ classification, and public transport usage frequency using socio-demographic survey data. The supervised machine learning algorithm, K-Nearest Neighbor (KNN) applied to build a predictive model, which is the better machine learning method for dealing with small datasets, because of its ability of having less parameter tuning. Survey data has been used to train and validate the model performance, which is able to predict public transport usage frequency of future users of public transport. This model can practically be used by public transport agencies and relevant government organizations to predict the public transport demand for new commuters before introducing any new transportation projects.
Modelling the Bioclimatic Niche of a Cohort of Selected Mite Species (Acari, Acariformes) Associated with the Infestation of Stored Products
Authors: Tytar V. M. , Oksentyuk Ya. R. 
Published: January 2020

Abstract
In this study an attempt is made to highlight important variables shaping the current bioclimatic niche of a number of mite species associated with the infestation of stored products by employing a species distribution modeling (SDM) approach. Using the ENVIREM dataset of bioclimatic variables, performance of the most robust models was mostly influenced by: 1) indices based on potential evapotranspiration, which characterize ambient energy and are mostly correlated with temperature variables, moisture regimes, and 2) strong fluctuations in temperature reflecting the severity of climate and/or extreme weather events. Although the considered mite species occupy man-made ecosystems, they remain more or less affected by the surrounding bioclimatic environment and therefore could be subjected to contemporary climate change. In this respect investigations are needed to see how this will affect future management targets concerning the safety of food storages.

Abstract
For the first time, an analysis of structural damage of the peripheral blood erythrocyte nucleus in Rutilus rutilus (Linnaeus, 1758) was carried out for the rivers of the north-western region of Ukraine. The effect of the hydrochemical regime on the formation of cytogenetic disturbances of the representatives of this species was also clarified. It was observed that during 2013–2017, the content of phosphates, suspended solids, fluorides, iron, copper, zinc, manganese, nitrite nitrogen and nitrate nitrogen in the surface waters of rivers most significantly exceeded the current quality standards. The average frequency of nuclear disorders of peripheral blood erythrocytes R. rutilus from the studied hydrosystems is 5.25 ± 0.29 ‰ (p < 0.01), with a noticeable excess of the level of spontaneous mutations in the older age groups of fish. In all analyzed samples of R. rutilus, among the total number of identified structural disorders of the nucleus, the largest share is made up of red blood cells from the micronucleus (from 40.0 to 62.0 %), which is evidence of cytogenetic disturbances in the body of fish. At the same time, disturbances of erythrocyte blood of roach from small rivers are on average 1.3 times (or 21.9 %) higher compared with individuals from medium-sized rivers. The formation of cytogenetic disturbances in R. rutilus under the conditions of the hydrochemical regime of rivers is described by a close (r = 0.99 at p < 0.003) multifactorial regression dependence. More important regressive coefficients of the dependency are acquired by such biogenes (NH4+, NO3−, PO4−) and toxicants (Cu2+, Zu2+, Mn2+, F2) in the background of oxygen regime peculiarities (COD, BOD5, O2).
Artificial Light at Night as a New Threat for Nature Conservation in Ukraine
Authors: Peregrym M. , Vasyliuk O. , Kónya E. Pénzesné 
Published: January 2020

Abstract
Human society benefits a lot from artificial light at night (ALAN), but in the same time it has led to a significant increase in light pollution of the night sky during the past decades. It has serious consequences on reproduction, navigation, foraging, habitat selection, communication, trophic and social interactions of the biota. Also widespread incursion of ALAN within protected areas has been evidenced for some countries, including the National Nature Parks (NNPs), Biosphere and Nature Reserves in the Steppe Zone and Crimea Mountains of Ukraine. However, the common situation with ALAN impact on protected areas within Ukraine is unclear yet. This research attempted to estimate the level of light pollution on the NNPs, Biosphere and Nature Reserves in the Forest, Forest-Steppe zones and Carpathian Mountains within Ukraine. Kmz layers of these protected areas and the New World Atlas of Artificial Sky Brightness, through Google Earth Pro, were used to calculate the level of artificial sky brightness for 33 NNPs, 2 Biosphere Reserves and 9 Nature Reserves. The results show that majority of studied protected areas are impacted by ALAN, but some of them stay almost under the dark sky still. The situation is unique for Europe, therefore these areas have the special value for biodiversity conservation and can be recognized as refugia where natural habitats are not influenced by ALAN. Based on obtained results, recommendations for improving of nature conservation management are given in the context of ALAN problem.
Modelling the Bioclimatic Niche and Distribution of the Steppe Mouse, Mus Spicilegus (Rodentia, Muridae), in Ukraine
Authors: Tytar V. M. , Kozinenko I. I. , Mezhzherin S. V. 
Published: January 2020

Abstract
The Steppe mouse, Mus spicilegus, is endemic to Europe and found to be expanding its home range in recent years. In Ukraine there are indications a north- and eastwards expansion and/or reestablishment of M. spicilegus. We suggest that climatic conditions may be the primary factors that foster or limit the range expansion of M. spicilegus in Eastern Europe. Our objective was to complement the knowledge about the distribution of the species with an estimation of the potential distribution of the species in Ukraine using known occurrence sites (in Ukraine and neighbouring areas) and environmental variables in an ecological niche modelling algorithm. After accounting for sampling bias and spatial autocorrelation, we retained 73 occurrence records. The algorithm used in this paper, Maxent (Phillips et al., 2006), is a machine learning algorithm and only needs presence data, besides the environmental layers. Using this approach, we have highlighted the importance and significance of a number of bioclimatic variables, particularly those characterizing wintering conditions, under which higher mean temperatures enhance habitat suitability, whereas increased precipitation leads to an opposite effect. The broadly northwards shift of the home range of the species in Ukraine could generally be due to the increasing (since the 1980s) mean temperature of the winter season. We expect this expansion process will continue together with the changing climate and new records of locations of the species may be used for monitoring such change.

Future of Shipping
Authors: Powell J 
Published: January 2020

Technology is changing and rapidly evolving many industries including shipping. Advances in information, telecommunication, computer, robotic, Artificial Intelligence, machine/deep learning technologies together with cutting edge automation are proliferating every facet of maritime industry and changes are expected to accelerate. However, challenges of new technologies, pace of change and wide spread automation have taken many by surprise. In maritime, the regulatory framework which has often been the cornerstone and by and large the driving force for change, albeit in response to an event or market forces or political pressure, is conspicuously missing and currently engaged in a race against time to catch up and rework the applicable Conventions. Despite early success, there are indeed numerous challenges for the new technologies to bed in and gain wider acceptance and recognition before being considered as a worthy and viable replacement for tried and tested designs on a global scale. Various projects developed thus far or undergoing development, are exclusively intended for coastal waters and therefore, subject to class and Flag national requirements and in the circumstance, rules and regulatory requirements are devised and enforced at national level, as deemed fit. Successful and historical Rolls Royce-Finferries autonomous operation of car ferry Falcon, underlined the arrival of new technologies and demonstrated that it is no longer a question of if but when, wide spread use of automation and autonomous systems are implemented on board. There are of course many hurdles to overcome but with the buzz, energy and willingness of stakeholders in maritime nations and scales of investment in research and development, it is only a matter of time before unmanned, semi-autonomous, autonomous vessels join the world fleet in numbers and set the trend for a new era in shipping. With steady and continuous growth in world trade and world fleet, indications are that current shortfall for officers will be multiplied by 2025. Although, there are no reliable records for total number of qualified seafarers worldwide and perhaps seafarers available for work, there will reportedly be a substantial shortfall in the number of officers by 2025, as per (BIMCO-ICS 2015) Manpower Report. This paper attempts to examine underlying reasons for introduction of new and viable technologies for potentially unmanned, semi and fully autonomous operations and its socioeconomic impact on seafarers and affiliated workforce.

Authors: Kurniawati Diyan 
Published: January 2020

This paper discusses the importance of city space for humans who live in it in the anthology of Salome and Orang-Orang Balikpapan. It uses sociological theory of literature and a theory of urban space. This study analyzes the position of humans in urban space and the importance of urban space for humans who live in it. Human position is displayed in various socio-economic classes. Therefore, relations between people in those various socio-economic classes will also be analyzed. It shows that the journey of human beings maintaining their existence in the city space brings together humans to other humans with various social, economic, and cultural backgrounds. Humans who migrate to urban spaces find attention and empathy from the others so that they can find new family and homes. The defense of their existence that is full of competition can cause other humans to develop empathy. In urban space, humans do not only buy and sale things, demand rights, and carry out obligations, but also can still show empathy to the others. Empathy demonstrated through attention to the development of others, especially children, is also a form of empathy that is very beneficial to the others. Short stories in Salome and Orang-Orang Balikpapan show humans in the urban space who maintain their social values in their intense competition maintaining their existence.
