The Effects of Dietary Supplementation of Encapsulated Thyme Essential Oil on Growth, Pro-Inflammatory Cytokines, and Serum Amino Acid Profiles of Broiler Chicks Challenged with Salmonella Typhimurium
Authors: Olfati Ali , Hosseini Seyed Majid 
Published: May 2021

Abstract

Salmonella Typhimurium (S. Typhimurium) causes inflammation and has adverse effects on the growth of broiler chicks. Meanwhile, plant derivations improve the growth performance and decrease inflammation, but they do not have enough stability. Encapsulation of essential oils is a new strategy for decreasing their instability. This study was conducted to investigate the effects of dietary supplementation of encapsulated thyme essential oil (ETEO) on growth, inflammatory cytokines, and amino acid profiles of broiler chicks challenged with S. Typhimurium. Three hundred one-d-old broiler chicks were assigned into 6 groups, and 5 replications per group. The broiler chicks (3 groups) were challenged with S. Typhimurium on day 21 and birds received basal diet (positive control), encapsulated thyme (P-ETEO), and non-capsulated thyme (P-NETEO), while other groups received the same diets, but under normal as a negative control, encapsulated thyme (N-ETEO) and non-capsulated thyme (N-NETEO). Growth performance, pro-inflammatory cytokines, and serum amino acid profiles were assessed on day 42. The challenged birds in positive control showed lower growth performance, higher concentration for inflammatory cytokines, and disturbed blood serum concentrations for amino acid profiles compared to the negative control (P<0.05). The result showed that dietary supplementation of the ETEO could improve growth performance and amino acid profiles, and also decrease inflammatory responses (P<0.05). In sum, S. Typhimurium had negative effects on growth, immunity, and inflammation, but dietary inclusion of the ETEO could decrease its negative effects.

Abstract
The aim of the study was to compare the advancement of the ripening as well as catabolic changes in proteins and fats of Zlotnicka Spotted (ZS) and Zlotnicka White (ZW) meat and their impact on the quality and nutritional value of ready-to-eat products. The meat of the breeds ZS and ZW differed not only in the basic chemical composition but also in the susceptibility to catabolic transformations of proteins and lipids, which translated into a separate technological and nutritional quality as well as the profile of volatile odor compounds. Loins due to their compact histological structure, low pH (5.4) and decreased water activity (0.92–0.93) were characterized by a lower number of coagulase-negative cocci (3.3 log cfu/g) compared to hams. The products of both breeds differed in the content of selected neutral glucogenic amino acids with a pI in the range of 5.6–6.1 mainly. The content of biogenic amines was therefore completely dependent on the metabolic potential of acidifying bacteria. Larger number of lactic acid bacilli (7.5–7.7 log cfu/g) and lactic acid cocci (7.9–8.3 log cfu/g), as well as a higher content of saturated (55.2–53.7%) and polyunsaturated fatty acids (6.4–7.0%) shaped the final pH of hams (5.3). Presence of aldehydes, ketones and alcohols indicated existing fat oxidation despite the small values of the TBA index of hams (1.1 mg/kg) and loins (0.4–0.6 mg/kg). The volatile compounds that differentiated products of ZS and ZW formed by the oxidation and microbial activity, were, primarily: octanal, 1-hydroxypropan- 2-one, 3-methylpentan-2-one, propane-1,2-diol, 2,5-dimethylfuran and 3-hydroxybutan- 2-one, butane-2,3-dione, butane-1,2-diol, respectively.

Abstract
The primary aim of this study was to estimate the relationship between ATP citrate lyase (ACLY) gene polymorphism (c.*523 T>C) and fattening and pork quality traits. Investigations were carried out on 526 pigs represented by three breeds: Polish Landrace (n=269), Polish Large White (n=189) and Puławska (n=68). ACLY genotypes were determined by PCR–RFLP method. It was demonstrated that the analyzed polymorphism had significant influence (P<0.05 and P≤0.01) on several economically important traits in pigs, e.g. average daily gain, average backfat thickness, lean meat percentage. The results obtained allow for application of c.*523 T>C polymorphism in breeding programs to improve the pig population in terms of fattening and slaughter traits. However, this breeding program may have a slight negative effect on meat texture parameters.

Published: May 2021

Abstract
The effect of storage time at a temperature of 8°C on the direction and dynamics of changes in quality traits of eggs was investigated in shelled table eggs obtained from different egg production systems (cage system – CS, barn system – BS, free-range system – FRS). After 7, 14 and 28 d of storage, eggs from each housing system were tested for physical characteristics and for cholesterol content and fatty acid profile in the yolk. The weight of eggs from all studied housing systems declined with storage duration. The rate of weight loss was smallest in eggs from CS (P<0.05). Storage duration influenced eggshell traits but the rate and direction of these changes did not differ among the studied housing systems. Albumen height and Haugh unit score for eggs from rearing systems under study declined during storage (P<0.05). The greatest reduction of albumen height (18.85%) after the storage period was observed for CS eggs and the lowest (13.24%) for FRS eggs (P<0.05). No effect of storage duration on yolk colour intensity was observed for eggs from all the studied housing systems (P>0.05). Albumen pH increased with storage duration in eggs from all the egg production systems (P<0.05). The increase in the yolk pH during storage was the highest in FRS eggs and the lowest in the CS eggs. The storage duration of eggs from the different housing systems did not significantly influence albumen foaming capacity but adversely affected foam stability. There was no impact of storage duration of eggs from different housing systems on cholesterol content in the yolk. Eggs obtained from the different housing systems showed diverse fatty acid profiles in the yolk but this parameter did not significantly change during storage (P>0.05).

Abstract
The design of workwear has significant effects on worker performance. However, the current workwear for coal miners in Northern China is poor in fitness and thermal comfort. In this study, new workwear (NEW) for coal miners was developed with the design features providing better cold protection and movement comfort performance, as compared with a commonly worn workwear (CON). To evaluate the effectiveness of NEW, we conducted human trials which were performed using simulated work movements (i.e., sitting, shoveling, squatting, and crawling) in a climate chamber (10°C, 75% RH). Physiological measurements and perceptual responses were obtained. The results demonstrated that the local skin temperatures at chest, scapula, thigh, and calf; mean skin temperatures,; and thermal comfort in NEW were significantly higher than those in CON. NEW also exerted an improvement in enhancing movement comfort. We conclude that NEW could meet well with the cold protective and mobility requirements.
Public sector innovation performance in Federation of Bosnia and Herzegovina: An exploratory factor analysis
Authors: Krndzija Lamija 
Published: May 2021

Abstract
Innovation has nowadays become the main force to cope with challenging times in the fast-changing world. The influence of public sector innovation (PSI) in resolving dynamic economical and societal challenges is undisputable. Regardless of the numerous advantages of innovation in the public sector (PS) which have been recognised worldwide, the concept of public sector innovation is still novel for the Federation of Bosnia and Herzegovina (FBiH). Moreover, there is limited empirical evidence which would facilitate the understanding of public sector innovation performance. The purpose of this paper is to identify main components of PSI performance. The primary research data was obtained through a survey with close-ended questions which was completed by the public sector institution employees in FBiH. The exploratory factor analysis (EFA) was used in order to determine the principal components of measuring public sector innovation performance. The EFA returned the factor-structures for all four suggested constructs, innovation capabilities, wider sector conditions for innovation, sources of information and the share of creative occupation, explaining between 65% and 78% of the variance of the innovation performance measurement construct. The results from the exploratory factor analysis provided a distinct estimation on the factor structure of measuring PSI. The paper has provided and analysed the first instrument in measuring public sector innovation performance in FBiH.
The EU's regional trade agreements: How the EU addresses challenges related to digital transformation
Authors: Slok-Wodkowska Magdalena , Mazur Joanna 
Published: May 2021

Abstract
The objective of this paper is to provide insight into the regulatory solutions that refer to the electronic commerce (e-commerce) adopted in the regional trade agreements (RTAs) of the European Union. Our goal is to compare these regulatory measures with the obstacles indicated in the literature as key issues hampering international digital trade. We provide a formal-dogmatic analysis of all of the newly adopted RTAs. The findings resulting from this analysis indicate that even though the regulatory dimension of global economic trade attempts to somehow address the issues resulting from the specific characteristics of the digital economy, the process is still in its infancy. The majority of provisions do not consider the key problems that impede international digital trade. The originality of our work results from its focus on the most recent RTAs, the analysis of which is hardly present in the scholarship.
Machine Learning in Terminology Extraction from Czech and English Texts
Authors: Kováříková Dominika 
Published: May 2021

Abstract
The method of automatic term recognition based on machine learning is focused primarily on the most important quantitative term attributes. It is able to successfully identify terms and non-terms (with success rate of more than 95 %) and find characteristic features of a term as a terminological unit. A single-word term can be characterized as a word with a low frequency that occurs considerably more often in specialized texts than in non-academic texts, occurs in a small number of disciplines, its distribution in the corpus is uneven as is the distance between its two instances. A multi-word term is a collocation consisting of words with low frequency and contains at least one single-word term. The method is based on quantitative features and it makes it possible to utilize the algorithms in multiple disciplines as well as to create cross-lingual applications (verified on Czech and English).
Grammatical Tenses and Communicative Intentions: A case study of the German Perfekt and Präteritum
Authors: Concu Valentina 
Published: May 2021

Abstract
Recent research in syntax and corpus linguistics has shown how the German Perfekt (present perfect) and Präteritum (simple past) are widely used in written language—even though these tenses are commonly described in DAF (German as a foreign language) materials as used respectively in the spoken and written forms. While these analyses only focus on written corpora, an extensive study on the use of tenses in spoken interaction is still missing. In this paper, I try to fill this gap in the literature by exploring the use of Perfekt and Präteritum in the recordings of the Frankfurt Auschwitz trials, held in Frankfurt am Main, from December 20, 1963, to August 19, 1965, and available on the web page of the Fritz Bauer Institute. Textual analyses of the depositions of five former German prisoners of the Polish concentration camp show that German native speakers use both tenses in their spoken interactions. These results widely contradict their depiction in DAF materials, textbooks, and grammars. Furthermore, the types of Präteritum found are far more diverse than is traditionally held by scholars, who claimed that the use of this tense in spoken language is limited to verbs such as sein (to be), haben (to have) and modals, such as können (can), müssen (must), sollen (should), etc. The outcome of this study shows how the difference between Perfekt and Präteritum is determined by the subjective attitude of the speakers in relation to the information they want to convey.
Finite element modeling of continuous drive friction welding of Al6061 alloy
Authors: Tashkandi Mohammed A. 
Published: May 2021

Abstract
Continuous drive friction welding process is widely used in various industrial applications to assemble shafts, tubes, and many other components. This paper's motivation was developing a CDFW model using the Finite Element Method (FEM). The coupling of the process's thermal and mechanical behaviors was considered during the simulation by COMSOL Multiphysics®. The construction of phase transition curves for Al6061 allowed determining several temperature-dependent thermophysical properties of the material. These properties are then injected in a second simulation to study the temperature evolution during welding. Subsequently, these results are compared and analyzed with the experimental outcomes. Excellent comparability between the model and experimental results was achieved. A unique phenomenon in the welding temperature profile was observed and explained through the model and experimental results interpretation.

Abstract
Zero-dimensional two-stage SOFC stacks dynamic model was developed to investigate the effect of operating parameters on stacks performance. The model resolves spatially thermal and thermo-electrochemical behaviour for electrochemical reactions, Catalytic Partial Oxidation and Steam Reforming processes. Design variables and thermo-electrochemical properties were obtained from in-house-fabricated SOFCs carried out by project partners. The completed SOFCs based Combined Heat and Power, CHP, system model was validated by data

and numerical results obtained at steady-state mode showing its high-fidelity. A parametric study with respect to key operating parameters including changes in fuel utilization, lambda number and current density values was conducted. The global CHP system dynamic response, in term of the current/voltage delivered by two-stage SOFC stacks, under a fixed fuel utilization, has been determined resulting in greater variations in the voltage of a single cell in the first stack in comparison to the corresponding values in the second stack.

Published: May 2021

Abstract
To make clear the feasibility and influence factors of diesel fuel autothermal reforming to hydrogen, PdCeCr- FeCu/Al2O3 catalyst was prepared by equivalent-volume impregnation method. Experimental facility based on an adiabatic tubular reactor with preheating section was designed and set up, the behaviors of diesel reforming to hydrogen with straight-run diesel as a raw material according to the analysis of the components were studied. Diesel oil reforming over a catalyst for hydrogen production was analyzed using an adiabatic tubular reactor with a preheating section that was designed and built in-house. The operating conditions were optimized. Under the suitable operating conditions, viz., catalyst bed inlet temperature of 700 °C, diesel liquid space velocity of 0.24 h−1, water-carbon ratio of 20, and oxygen-carbon ratio of 0.6, the hydrogen yield reached 28.3 (mol/mol).
Doing Orthodox Political Theology Today Insights from the Document For the Life of the World: Toward a Social Ethos of the Orthodox Church (2020)
Authors: Asproulis Nikolaos 
Published: May 2021

Abstract
The document titled For the Life of the World: Toward a Social Ethos of the Ortho dox Church, authored by a special commission of Orthodox scholars appointed by the Ecumenical Patriarch Bartholomew is a document that can be definitely understood as a political manifesto of Eastern Orthodoxy for the 21st century, namely for this period of history and not for a by-gone historical setting or a Christian utopia (either the Byzantine Empire or Holy Russia), a period of time with urgent problems and challenges that call for our attention. Therefore, bringing to the fore the personalist anthropological view inherent in the document itself, an attempt has been made in the text to critically reflect and highlight certain relevant aspects of the document (a positive reception of liberal democracy, human rights language, solidarity to the poor, etc.). The goal is to show how theologically important this document is for the Church witness to our pluralistic world.
Truth or Diplomacy? For the Life of the World, Islam and the Patristic Approach
Authors: Seppälä Serafim 
Published: May 2021

Abstract
In their writings on Islam, John Damascene and Theodore Abu Qurrah, both authoritative patristic saints of the Orthodox Church, took an apologetic and polemic stand in defence of the Christian truth. In the modern interreligious discourse, however, the approach to Islam is rather diplomatic, concentrating on universal human values and common aspects of religions. How does the document For the Life of the World operate in this tension? In general, it aims to build on patristic argumentation, but the approach to Islam is most positive and all-embracing, welcoming the “beauty and truths” of Islam and stressing the “common roots,” while the patristic views on Islam are silenced. The discrepancy may arouse questions on the sincerity and coherence of the modern approach in relation to the patristic tradition. This reflects wider challenges in the modern theology of the Church: how to find a discursive position in the tension between the defence of truth, characteristic for the patristic thought, and the “diplomatic” language of the modern interreligious encounters.

Abstract

Introduction. Information on healthcare-associated C.difficile infection (HA-CDI) in COVID-19 patients is limited. We aimed to assess the characteristics of HA-CDI acquired during and before the COVID-19 pandemic.

Methods. We conducted a retrospective study in a tertiary care hospital, in which since March 2020 exclusively COVID-19 patients are hospitalized. We compared HA-CDI adult patients hospitalized in March 2020-February 2021 with those hospitalized during the same period in 2017–2018.

Results. We found 51 cases during 2020–2021 (COVID-19 group), incidence 5.6/1000 adult discharge and 99 cases during 2017–2018 (pre-COVID-19 group), incidence 6.1/1000 adult discharge (p=0.6). The patients in COVID-19 group compared to pre-COVID-19 group were older (median age 66 vs 62 years), with similar rate of comorbidities, but with higher rate of cardiovascular diseases (62.7% vs 42.4%) and less immunosuppression (21.6% vs 55.6%), they had a higher proton pump inhibitors use (94.1% vs 32.3%), and a longer hospitalization (median 19 vs 14 days).
Eighty-five (85.9%) patients in pre-COVID-19 group versus 44 (86.3%) patients in COVID-19 group received antimicrobial treatment – mainly cephalosporins (34,1%), quinolones (22,3%) and glycopeptides (21,1%) in pre-COVID-19 group and mainly cephalosporins and macrolides (63,6% each) in COVID-19 group. We found four HA-CDI-related deaths in pre-COVID-19 group and none in the COVID-19 group.

Conclusions. The HA-CDI incidence in COVID-19 group did not change versus the same period of time during 2017–2018. The antibiotic use was the most important factor associated with HA-CDI. We identified a high use of broad-spectrum antibiotics despite the lack of empirical antimicrobial recommendations in COVID-19.

Published: May 2021

Abstract
The aim of the study is to evaluate the effect of 4-hydroxy-3,5- di-tertbutyl cinnamic acid on the change in mitochondrial function under conditions of experimental cerebral ischemia in rabbits. The study was performed on 48 male rabbits, which were used for modeling permanent cerebral ischemia by occlusion of the common carotid arteries. The test compound was administered before modeling ischemia for 14 days and after the occurrence of reproducing ischemia, in a similar time interval. After that, neurological deficit and the parameters of mitochondrial respiration, the intensity of anaerobic processes, the latent opening time of the mitochondrial permeability transition pore, the value of the mitochondrial membrane potential and the concentration of caspase – 3 were determined. The administration of 100 mg/kg of 4-hydroxy-3,5-di-tertbutyl cinnamic acid into the animals reduced neurological deficit and restored the mitochondrial membrane potential. Prophylactic administration of 4-hydroxy- 3,5-di-tertbutyl cinnamic acid, contributed to an increase in ATPgenerating ability, the maximum level of respiration and respiratory capacity by 4.1 times (p<0.01), 4.8 times (p<0.01) and 4.3 times (p<0.01), respectively. With therapeutic administration, these indicators increased by 11 times (p<0.01), 12.2 times (p<0.01) and 8.6 times (p<0.01), respectively. Also, both the prophylactic and therapeutic use of 4-hydroxy-3,5-di-tret-butyl cinnamic acid normalized aerobic/anaerobic metabolism, as well as reduced the concentration of caspase-3. Based on the obtained data, significant cerebroprotective properties of 4-hydroxy-3,5- di-tertbutyl cinnamic acid can be assumed. Moreover, the potential mechanism of action of this compound may be mediated by the normalization of mitochondrial function.
