Authors: Olutegbe Nathaniel Siji , Olawoye Janice Elaine , Oyesola Olutokunbo Birdies 
Published: April 2021

Abstract
The study investigated the well-being of rural households around Ikere-Gorge dam operated in South-western Nigeria. Ninety rural households were sampled in four communities, using a multistage sampling procedure. Data were analysed using frequency counts, percentages, means and Pearson Product Moment Correlation (at α0.05). Majority of the household heads were males (84.4%), married (86.7%), Christians (56.7%), had no or primary education (74.5%) with average age of 42.28 ± 7.63 years. Marginalization by government (91.1%), elite capture of support services (90.0%) and lack of extension services (83.3%) were rated major constraints to livelihood by majority. The dam served benefits such as availability of water for domestic use (x¯ = 2.83), improved socioeconomic development (x¯ = 2.56), and recreational and tourism services (x¯ = 2.42). Both quality of life (x¯ = 1.73) and health (x¯ = 1.88) indicators of well-being were generally low. Constraint to livelihood had a significant relationship (r = −0.323) with respondents’ overall well-being. The study concluded that households around dams are faced with multi-dimensional challenges at varying degrees, with negative implications for livelihood and well-being of rural households.

Abstract
The occurrence and compositional pattern of priority pollutants are vital in understanding the anthropogenic contributions, origin, and risks of these pollutants to the surrounding environment. Thus, the focus of this study was to determine the concentrations, compositional profiles, and sources of aliphatic hydrocarbons (AHCs) in anthropogenic impacted soils from petroleum tank-farms environment in the Niger Delta, Nigeria. Forty-five soil samples were collected from the vicinity of petroleum tank-farms at the top (0-15 cm), sub (15-30 cm), and bottom (30-45 cm) soil depths. The concentration of AHCs was determined using gas chromatography-mass spectrometer (GC-MS) after extraction by ultrasonication with hexane/dichloromethane and clean-up in silica gel/alumina packed column. The mean concentrations of AHCs in the samples ranged from 0.52 ± 0.90 to 35.26 ± 35.69 mg/kg. The AHCs results show that the equivalent carbon number index (ECn-) ECn-13-35 had the highest concentration when compared to ECn-8-12 and ECn-36-40. The linear regression and ANOVA indicate that there is no significant positive correlation between TOC and the total concentration of AHCs in the soil profiles, and a significant variation in AHCs levels between soil profiles respectively. Results also showed that soils from the tank-farms are moderately contaminated with AHCs when compared to the UNEP recommended limit. However, when compared to other regulatory thresholds, the observed concentrations of AHCs, human and environmental health risks are likely. Source apportionments depict that the principal sources of AHCs were petrogenic and plant diagenesis. Appropriate clean-up and mitigation measures and further study to determine the occurrence, composition, and exposure risks of other priority pollutants in water and sediment samples from the surrounding creeks should be determined.

Published: April 2021

Abstract
The presence and impact of bulk and rhizosphere microorganisms in contaminated soils can be huge, given that they have the ability to increase plants tolerance against abiotic stress, and also enhance plant growth, while supporting hastened remediation of disturbed soils. The present study quantitatively and qualitatively assessed presence of cultural fungi and bacteria during phytoremediation of heavy metal polluted soils using Chromolaena odorata. Stem cuttings of C. odorata were planted in soils polluted with Pb, Mn, Zn, Cd, and Cu at once (1ESC), thrice (3ESC) and five (5ESC) times their respective ecological screening concentrations (ESC). ESC of Pb, Mn and Zn is 50 mg/kg, Cd is 4 mg/kg, and Cu is 100 mg/kg. After 6 months, results showed that more than 10 species of bacteria and fungi were identified in the study, with P. aeruginosa and Bacillus subtilis being the most occurring bacteria while, Penicillium sp. and Aspergillus niger the most occurring fungi in both bulk and rhizospheric soils. The presence of known plant growth promoting rhizobacteria in plants rhizosphere including Azotobacter sp., Bacillus subtilis, B. pumilus, Clostridium sp., P. aeruginosa, and Klebsiella sp. was also reported.
“In a Sea of Wonders:” Eastern Europe and Transylvania in the Irish-Language Translation ofDracula
Authors: De Brún Sorcha 
Published: April 2021

AbstractThe publication of the Irish-language translation ofDraculain 1933 by Seán Ó Cuirrín was a landmark moment in the history of Irish-language letters. This article takes as its starting point the idea that language is a central theme inDracula.However, the representation of Transylvania in the translation marked a departure from Bram Stoker’s original. A masterful translation, one of its most salient features is Ó Cuirrín’s complex use of the Irish language, particularly in relation to Eastern European language, character, and landscapes. The article examines Ó Cuirrín’s prose and will explore how his approaches to concrete and abstract elements of the novel affect plot, character, and narration. The first section explores how Dracula is treated by Ó Cuirrín in the Irish translation and how this impacts the Count’s persona and his identity as Transylvanian. Through Ó Cuirrín’s use of idiom, alliteration, and proverb, it will be shown how Dracula’s character is reimagined, creating a more nuanced narrative than the original. The second section shows how Ó Cuirrín translates Jonathan Harker’s point of view in relation to Dracula. It shows that, through the use of figurative language, Ó Cuirrín develops the gothic element to Dracula’s character. The article then examines Ó Cuirrín’s translations of Transylvanian landscapes and soundscapes. It will show how Ó Cuirrín’s translation matched Stoker’s original work to near perfection, but with additional poetic techniques, and how Ó Cuirrín created a soundscape of horror throughout the entirety of the translation.
Evaluating the Level of Burnout among Healthcare Professionals
Authors: Makkai Kinga 
Published: April 2021

Abstract
The professional staff in human service institutions are often required to spend considerable time in intense involvement with other people. Frequently, the staff–client interaction is centered around the client’s current problems (psychological, social, and/or physical) and is therefore charged with feelings of anger, embarrassment, fear, or despair. Solutions for these problems are not always obvious and easily obtained, thus adding ambiguity and frustration to the situation. For the helping professional who works continuously with people under such circumstances, the chronic stress can be emotionally draining and poses the risk of burnout. Extensive literature highlighted that healthcare professionals’ work is relentlessly overloaded, emotionally overwhelming, escalating their private life, and thus favoring burnout development. In the present research, there was found a significant difference (p < 0.001) between the burnout level (Maslach HSS) of staff working in state hospitals and staff working in private hospitals. None of the other differences were significant: age (p = 0.155), gender (p = 0.083), work experience (p = 0.480), and job (p = 0.015).
Bending Failure Behavior of the Glass Fiber Reinforced Composite I-Beams Formed by a Novel Bending Pultrusion Processing Technique

Published: April 2021

Abstract
The glass fiber reinforced resin matrix composite I-beams were designed and formed via a type of novel bending pultrusion processing technique, and the three-point bending tests were carried out to analyze the mechanical bending performances. The obtained results show that the main failure mode of the composite I-beam under the bending load is the upper structure (top flange) cracks along the length direction of the fibers, and the cracks simultaneously propagate downwards in the vertical direction. The bifurcated cracks can be found at the junction area between the top flange and web. In addition, the main bending failure mechanism of the composite I-beam includes the matrix cracking, propagation of cracks, and final fracture failure. In particular, noting that when the crack reaches the I-shaped neck position, the lateral bifurcation occurs, and the resulting secondary cracks further extend in two directions, which leads to the serious damage between the top flange and web, and the ultimate fracture failure occurs.

Published: April 2021

Abstract
The purpose of this study was to investigate the effect of synbiotic and organic acids on oxidative stability of breast broiler meat. The experiment consists on 120, 2 days old Ross 308 chicks, housed in metabolic cages (6 chicks/cage). A 2 x 2 factorial arrangement was considered with 4 treatments and 5 replicates (30 animals per group). Two different levels of synbiotic (0 and 10 g/kg) and two different levels of organic acids (0 and 1.5 g/kg) were added to the standard diets in order to constitute the four experimental diets. For further analysis, breast meat from 6 animals per group were collected in 42nd experimental day. No significant differences were noticed for any oxidative parameter measured in breast samples except TBARS (significant decreased values for OA supplemented groups), at the end of experiment. After 4 days of refrigeration (4°C), the secondary oxidative products (panisidine, TBARS) were significant smaller for E groups, compared to C. After 7 days of refrigeration (4°C), the OA groups had significant smaller values for primary (CD) and secondary oxidation products. Synbiotic and organic acids supplements presented positive effect on meat quality by increasing oxidative stability of breast meat during storage.

Published: April 2021

Abstract
The composition of gastrointestinal tract microbiota can be changed by dietary manipulation, to prevent gut health issues and to promote animal performance. This study was conducted to investigate the effects of rice bran and alfalfa meal on growth performance and intestinal microbiota in broilers. A total of 252 Cobb 500 broilers, aged 14 days, were randomly assigned into 3 groups: control (CON), 5 % rice bran (RB), 5 % alfalfa meal (AM), and housed in an environment-controlled hall 42 days. Throughout the experimental period, grow performance parameters were monitored and at the end relative weights of internal organs were measured. Samples of intestinal content were collected for bacteriological determinations.
Feed intake, daily weight gain and viability were not significantly affected by the dietary supplements. Alfalfa meal and rice bran decreased the populations of Escherichia coli and staphylococci in small intestine content, and Enterobacteriaceae, Escherichia coli and staphylococci in caecal content of broilers. The count of lactobacilli in both small intestine and caecal content registered a significantly increase in experimental groups, compared to CON group.
Supplementation of diets with rice bran and alfalfa meal tended to increase the population of beneficial bacteria and inhibit the potential pathogens.

Abstract
The present work was planned to test the effects of 2 protein-oil rich ingredients which replaced an important part of classical soybean meal, on nitrogen (N) metabolism indicators. Simultaneous we aimed to assess performances, enteric methane (CH4) and carbon dioxide (CO2) emitted through manure. A balance test was conducted with 15 barrows, 36 ± 0.24 Kg initial body weight, assigned in three groups in metabolism cages: 1. SC diet based on a classical diet (soybean meal, 13%); 2. SP diet based on peas Tudor variety 16% that replace 49% of SM; 3. SPF diet containing 8% soybean meal, 12% peas and 4% linseed Lirina variety. Faecal and urine were quantitatively collected in two balance periods. A semiautomatic Kjeldahl method was used for assessing the N. The Spotchem EZ SP-4430 was used for determining plasma protein and urea nitrogen (BUN). The regression equations were used to determine N metabolism indicators, CO2 emitted and enteric CH4. An increase of 1.16 times of feed intake was noticed in the SP group compared to SC. The lipid intake was slightly higher in the SP fed group which contributed to an increase of energy intake compared to SC group (>1.17 times) and vs SPL fed group (>1.2 times). The average daily gain (ADG) decreased highly significant in the SP diet compared to the SC diet. Linseed adds in SPL diet contributed to obtaining performances closed to SC group. SP diets increased the N level slightly in faeces and urine. BUN concentration has a linear relation with urinary N. CO2 emitted represent 28-32% of CO2 exhalation. CO2 increased in the SP diet (P<0.10) due to the fact that HP value increased as well. No significant influence was noticed for CH4 estimated value, although a slight increase was observed in the SP diet. In conclusion, although certain N metabolism indicator was affected by peas diet, only a little part was significantly modified. An oil-rich ingredient such as linseed could successfully complement peas by diminishing its adverse effects.

Published: April 2021

Abstract
Research on a critically endangered and protected population of Trapa natans was carried out during growing season in 2016 at the site located on the Obnica channel within the region of Międzyodrze. It is a location that is close to the one indicated in historical sources by Winkelmann over 120 years ago. The post-war research did not confirm presence of this species within the region of Międzyodrze despite favourable biological conditions. The sites were declared relict and documented only in stratigraphy of peat deposits, detritus gyttja and bottom mineral sediments. Recently, an assessment of the population and habitat status were carried out. The appropriate indicators of the species status were examined according to the methodology of Chief Inspectorate of Environmental Protection. The floristic composition of Trapetum natantis association patches found within the researched site were analysed, reed bed associations belonging to the class of Phragmitetea and plant communities of pleustophytes, nymphaeids and elodeids belonging to the class Potametea and Lemnetea were recognised in the contact zone. On the basis of the collected data, particular attention was paid to the relevance of Trapa natans monitoring­ at the site located on the Obnica channel within the Międzyodrze region due to its indicative character. The conservation status of the population could be influenced by the change of water trophy within Międzyodrze channels caused by different forms of anthropopressure, including commercial use of this water body, hydromeliorative works, changes that are due to the progressive succession of water plants and reeds, which slow down the water flow rate within the area of Międzyodrze, favour accumulation of organic matter and increase of water trophy as well as fluctuations of surface water thermal activity caused by changing weather conditions.
The concept of technological proximity in the development of European Union national innovative systems
Authors: Rastvortseva Svetlana , Amanalieva Aizhan 
Published: April 2021

Abstract
The development of national innovative systems is intended to solve a number of issues: from decreasing socio-economic inequality in countries and regions to creating environments favourable to new high-tech production and diversification of industrial composition. Determination of the possibilities for expanding the set of innovative types of economic activity must be scientifically substantiated, since significant financial, material and human resources may be consumed in creating and supporting new economic sectors within the framework of state policy. This article contains an attempt to create a mechanism for revealing promising trends in the development of an innovative economic sphere, taking into account comparative advantages in the commodity composition of exports by determining technological proximity indicators. The article aims to substantiate the possibility of using the concept of technological proximity in developing national innovative systems. The study employs technological proximity indicators based on the revealed comparative advantages (RCA) of countries by commodity groups of export. A matrix of technological proximity in the industrial fields (at a six-unit level) for 28 countries of the European Union in 2007–18 was made. The results revealed comparative advantages by groups of high-tech products in EU countries in real time. The analysis of technological proximity in the industrial sector has shown the types of economic activity connected with the innovative sector, which was used to determine the countries’ degree of participation in the manufacture of high-tech products. The proposed mechanism can be used in the development and implementation of national and regional policy in the sphere of innovative systems, since it allows promising areas for creation and support of new high-tech productions to be determined.
Procedeul Repetiţiei Și Valenţele Sale – Indicatoare Semantice În Construcţia Poetică Blagiană
Authors: Farmatu Teona 
Published: April 2021

Abstract
By analyzing the Lucian Blaga’s poetry, this paper aims to argue how the form of poems contributes significantly to the creation of meaning through the stylistic figure of repetition. From the first volume, „Poems of light”, the repetition gains, beyond an aesthetic function, an ontic one specific to the Lucian Blaga’s consubstantiality between the poetic subject and the universe. During this approach, the repetition multiplies its phenomenalizations, in order to a significant part of the global meaning of the text is due to it. The major conclusion of this paper consists in highlighting a pattern of a continuous and ethereal aspiration to the self-world osmosis depending on Blaga’s creative stages.

Security Issues in the Integrated Management Perspective
Authors: Potoczek Andrzej 
Published: April 2021

AbstractSecurity is a system of interrelated elements that interact with each other and must be effectively managed. At the same time, security is one of the key areas of administrative activity. Nowadays, an integrated approach to the development process in the context of shaping local security policy becomes extremely important. Integrated management is based on a territorial-functional approach and exposes mutually balanced links between the economic, social and environmental systems of which security is a common element.
Superstitious beliefs about earwigs (Dermaptera)
Authors: Brandstaetter Frank 
Published: April 2021

Abstract
Earwigs are amongst the most misunderstood animals in the world. A widespread belief accuses them of entering human ears and causing severe damages to ear and brain. Although there is no evidence for any asscociation between earwigs and (human) ears, the common names of these insects in nearly every European language refer to that fact. The myth is probably originating in the scriptures of Pliny the Elder. References in old Germanic indicate the origin of the naming as far back as the beginning of the first millenium.

Singular Terms in Fiction. Fictional and “Real” Names (III Blasco Disputatio)
Authors: Abad Jordi Valor 
Published: April 2021

AbstractIn this introduction, I consider different problems posed by the use of singular terms in fiction (section 1), paying especial attention to proper names and, in particular, to names of real people, places, etc. As we will see (section 2), descriptivist and Millian theories of reference face different kinds of problems in explaining the use of fictional names in fiction-related contexts. Moreover, the task of advancing a uniform account of names in these contexts—an account which deals not only with fictional names but also with “real” names—will prove to be very hard no matter whether we favour realist or antirealist intuitions about fictional discourse (section 3). Section 4 offers an overview of the content of this volume, with emphasis on the discussion between Manuel García-Carpintero and Stacie Friend about the meaning of “real” names in fiction-related contexts, the main topic of the Third Blasco Disputatio.
