Authors: Chouikh Atef , Alia Fatma 
Published: April 2021

Abstract
This study aimed to evaluate the phytochemical properties, antibacterial and anti free-radical activities of Retama raetam extracts which is growing in the South-East of the Algeria Desert. The chemical screening showed the presence of many secondary metabolites such as tannins catechin, sterols and terpenes, and the absence of gallic tannins compounds. The obtained results demonstrated that the methanolic extract has shown moderate total phenolic and flavonoids contents (31.59 ± 2.82 mg AG E/g extract and 14.35 ±1.02 mg Qu E/g extract respectively). In the free radical DPPH test, the values of IC50 were converging in all extracts of R. raetam. The antibacterial activity of extracts has been tested against ten bacterial strains, were registered as the best inhibition zones with Vibrio cholera, Micrococcus luteus and Serratia marcescen. Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 25923 strains showed high resistance against most of all concentrations of extracts, and we noted the Gram-negative bacteria strains are the most sensitive to the different extracts of the plant. The qualitative analysis of extracts by using HPLC showed the contrast in presence of the phenolic compounds, such as in ethyl acetate extract registered absence of chlorogenic acid, also the absence of caffeic acid in 1-butanol extract. These results confirmed of the phenolic extracts of this plant are a source natural alternative to antibiotics and antioxidants.

Abstract
Carrot (Daucus carota L.) is one of the main root vegetables rich in bioactive compounds with appreciable health-promoting properties, largely consumed in Algeria. In the current study, the storage effect (at 4 °C throughout 12 days) on bioactive compound stability and the antioxidant activity of two Algerian orange carrot varieties (Supermuscade and Touchon) were investigated. Total phenolic content of samples was determined by the Folin–Ciocâlteu method. Antioxidant capacity was determined spectrophotometrically, based on the evaluation of Free Radical Scavenging Activity (FRSA) using DPPH radical and Ferric Reducing Power (FRP). The results showed that the Touchon variety is richer in phenolics, flavonoids, and carotenoids and presents higher antioxidant activity in comparison with the Supermuscade variety. At the end of storage, the bioactive compound content and antiradical activity increased significantly (p < 0.05). Also, an extremely significant correlation (p < 0.001) was observed between the antioxidant contents and the antioxidant capacities of aqueous carrot extracts.

Abstract
The physico-chemical and sensory qualities of pupuru analogues produced from co-fermented cassava and breadfruit blends were investigated. Cassava and breadfruit were processed separately and cofermented at different proportions to produce pupuru and pupuru analogues. Seven different samples were produced with the ratios of 100:0, 90:10, 80:20, 50:50, 20:80, 10:90, and 0:100 cassava:breadfruit respectively. The proximate composition, bulk density, hydrogen cyanide, pH, TTA, and sensory properties of the sample were determined using standard methods. The results showed that the protein (2.86–6.41%), fat (0.43–2.05%), ash (0.36–1.17%), crude fibre (0.68–2.83%), and energy values (393.84 to 399.38 kcal/100 g) increased together with breadfruit substitution. The bulk density, pH, total titratable acidity, and hydrogen cyanide content of the sample was in the ranges of 0.47–0.60 g/ml, 4.30–5.30, 0.18–0.31%, and 0.56–1.68 mg/100 g respectively. The pupuru analogues had lower hydrogen cyanide content than pupuru. The pupuru analogues up to 50% breadfruit substitutions had acceptable sensory attributes, comparable to pupuru. The study concluded that pupuru analogues of acceptable quality can be produced from co-fermented cassava and breadfruit; this entails increasing the utilization of breadfruit.
Biotic and abiotic risks of soil biochar treatment for food safety and human health
Authors: Kocsis T. , Pabar S. A. , Ferschl B. , Kotroczó Zs. , Mohási-Farkas Cs. , Biró B. 
Published: April 2021

Abstract
Pyrolysis technology facilitates the heating of organic waste biomass in a very low oxygen environment to temperatures over 400 °C. The high carbon content and surface area of the char produced via slow pyrolysis makes it suitable for a range of purposes that would sequester the carbon it contains. For example, there is a growing interest in its use as a soil amendment, which enhances plant growth and nutrient use efficiency.
The aflatoxin content of milk and dairy products as well as breast milk and the possibilities of detoxification
Authors: Csapó J. , Albert Cs. , Sipos P. 
Published: April 2021

Abstract
Aflatoxins are fungal toxins produced by Aspergillus species, which, due to increasing temperature and climate change in the temperate zone, appeared in the most important feeding plant and food ingredients. The most toxic of them is aflatoxin B1 (AFB1), which hydroxylates to aflatoxin M1 in the body of dairy animals and humans, and excretes in the milk. With the development of analytical methods, researchers are now able to detect toxins with a concentration of ng/kg. It was found that in most countries in Europe both breast milk and cow’s milk may contain AFM1, and therefore increased attention should be paid to the toxin content of milk, and that those above the limit should be excluded from consumption. In addition to cow’s milk, the AFM1 toxin content of breast milk can also be significant, the precursors of which are introduced into the mother’s body with food. Aflatoxins are highly resistant to physical, chemical, and microbiological effects, so the detoxification of foods, especially milk, is almost impossible. The best solution appears to be feeding the animals with toxin-free feeds or feeds containing toxins below the permitted limit, without giving opportunity to the toxins to enter the milk from the feed and from there into the human body.
Bioprotective potential of lactic acid bacteria
Authors: Laslo É. , György É. , András Cs. D. 
Published: April 2021

Abstract
Acidification in lactic-fermented foods is realized by lactic acid bacteria as an added starter culture or by autochthonous strains. These microbial strains possess different prominent features that define the technological, organoleptic, nutritional, and microbial safety aspects of the product. The bioprotective effect of the bacterial strains may be related to antagonistic properties against food spoilage and/or pathogenic strains. The aim of the present study is to determine the antimicrobial properties of three different food-grade lactic acid bacteria in order to use them as bioprotective cultures. Our findings show that the Lactobacillus pentosus, Enterococcus faecalis, and Pediococcus parvulus exerted a bacteriostatic effect on Escherichia coli and Bacillus cereus, whereas the Saccharomyces cerevisiae growth was not inhibited, which made them susceptible agent for co-culture systems.
T. W. Rolleston’s Ireland through a Polish Prism
Authors: McAteer Michael 
Published: April 2021

AbstractA founding member of the Irish Literary Society, an early member of the Gaelic League, and a leading figure in the Irish Co-operative Movement, Thomas William Rolleston was one of the most notable figures in movements for Irish cultural and economic revival during the late nineteenth/early twentieth century. Rolleston also had a keen interest in German literature and culture, developed originally from the four years that he lived in Wiesbaden and Dresden between 1879 and 1883. This experience granted him some appreciation of conditions that obtained in Germany prior to the outbreak of the First World War, including Prussian-Polish relations. In 1917, Rolleston published a significant pamphlet assessing Irish-British relations during the decades preceding the 1916 Rising in Ireland as compared with relations between Prussia and Poland over the same period. Rolleston rejects a widespread view in Ireland that the moral authority, which the British Government had accorded to itself as a defender of the rights of small nations in the war against Germany, had been fatally compromised by its willingness to countenance Polish independence while continuing to oppose Irish independence. This essay considers the contrasts that Rolleston draws between Ireland and Poland in 1917 in the light of his general views on the Irish language question and Irish politics during the 1900s.
(Mis)judging Ordinary Meaning?: Corpus Linguistics, the Frequency Fallacy, and the Extension-Abstraction Distinction in “Ordinary Meaning” Textualism
Authors: Klapper Shlomo 
Published: April 2021

Abstract
Rarely is a new yardstick of legal meaning created. But over the past decade, corpus linguistics has begun to be utilized as a new tool to measure ordinary meaning in statutory interpretation and original public meaning in constitutional interpretation. The legal application of corpus linguistics posits that an examination of every use of a term in a wide variety of documents can yield a more complete, impartial understanding of a word than can dictionaries, intuition, or an unsystematic survey of sources. Corpora could supplement, or even supplant, dictionaries and native-speaker intuition in legal analyses. For originalism in particular, legal corpus linguistics promises to offer what would be a more scientific methodology for a point of view which, until now, has lacked one.
However, corpus linguistics, as applied to legal problems, falls prey to a fatal methodological criticism – the frequency fallacy. The criticism states that in a corpus, an unusual meaning can have many corpus entries while a perfectly ordinary meaning can be completely absent from the corpus. That is, frequency is not a good measure of meaning. Since legal corpus linguistics relies on frequency, the corpus cannot inform legal meaning.
This article parries this otherwise fatal critique. It argues that while the frequency fallacy is self-evidently true, the fallacy is not inherent to the corpus, but rather is an artifact of misinterpreting the corpus by treating it like a dictionary. This defense consists of a number of steps. The first step distinguishes between two different methods of discerning ordinary meaning: extension and abstraction. As illustrated by Yates v. United States and United States v. Marshall, extension entails extending the statutory term to varying facts, while abstraction keeps the facts constant and abstracts out key qualities to find an appropriate term. Critically, this article argues that abstraction offers a way to avoid the frequency fallacy. Second, to use abstraction properly, one must analyze not only the presence of the legal term in question but also its absence; that is, one must determine the presence or absence of other terms to describe a similar factual scenario to distinguish between artifacts of language and facts about the world.
This article concludes by arguing that this method has a beneficial emergent quality. Not only does this answer make legal corpus analysis methodologically sound, but it also paves the way for the first tool to approximate how an ordinary person would read the law, thus potentially furthering the rule of law.

Published: April 2021

Abstract
The paper presents a study on the human learning process during the classification of stimuli, defined by motion and color visual cues and their combination. Because the classification dimension and the features that define each category are uncertain, we model the learning curves using Bayesian inference and more precisely the Normalized Conjunctive Consensus rule, and also on the base of the more efficient probabilistic Proportional Conflict Redistribution rule No 5 (pPCR5) defined within Dezert-Smarandache Theory (DSmT) of plausible and paradoxical reasoning. Our goal is to study how these rules succeed to model consistently both: human individual and group behaviour during the learning of the associations between the stimuli and the responses in categorization tasks varying by the amount of relevant stimulus information. The effect of age on this process is also evaluated.
Legal and Illegal Approach in Determining Terminological Equivalents in the Process of Translation on the Example of Selected Law Acts
Authors: Iluk Łukasz 
Published: April 2021

Abstract
Authors of translations of legal codes do not usually inform about their approach to solving translational problems. One of the reasons is the firm belief in the need for a faithful and thus literal translation of the output text. This unlawful approach creates a field for unfounded creation of so-called Equivalent terminology. Consequently, translations contain expressions whose meanings in the target language are incomprehensible or cannot be determined by reference to the doctrine or case-law. A legal approach based on subject knowledge and a precise methodology for determining interlingua equivalents eliminates the problems arising from a non-lawful approach. In the analytical part of the article there is presented a methodology of the legal approach to solving translational problems and the method of its practical application.
The occurrence of Hymenoptera: Aculeata on mine spoil heaps after shale extraction (Jakartovice, Nízký Jeseník Mts)
Authors: Poláček Rostislav 
Published: April 2021

AbstractThe devastation of natural components and the appearance of the landscape in connection with mining activities does not necessarily have only a negative impact. Post-mining landscape happens an important and recently the only place to live many species of organisms, plants and animals. In this context, the importance of these sites is mainly associated with Invertebrata including insects, which can replace their natural habitats. The author presents the results of his research on Hymenoptera: Aculeata on heaps created as unused waste after clay slate mining in the region of Nízký Jeseník Mts. This two-year research (2018–2019) focused on wasps, bumble bees and solitary bees was carried out at ten selected sites mainly in the cadastral area of the municipality of Jakartovice (Opava district).

Published: April 2021

Abstract
Microbial communities are known to be sensitive indicators for water pollution and biomonitoring assessment. In this study, we aimed at observation of microbial abundance and community composition in the mountain river Morávka. The results showed temporal and spatial changes in total cell abundance (TCA). TCA reached 105–106 cells/ml, increasing values were detected towards the mouth with maxima in summer and autumn months. Out of Eubacteria Betaproteobacteria and Cytophaga-Flavobacterium were found to predominate, while Archaea represented only 4.8 % of TCA. Along the flow three distinct patterns of phylogenetic groups' share were revealed related to increasing pollution. Microbial community composition was found to be most significantly dependent on the elevation and the sampling date. Moreover, environmental variables like O2 saturation, water temperature, trophic potential and pH influenced microbial community as well. Statistical analyses showed significant seasonal (23.5 %) and spatial (4.7 %) changes in microbial community composition.
Phylogeny of Tipulomorpha - an endless issue
Authors: Starý Jaroslav 
Published: April 2021

Abstract
Phylogeny of the infraorder Tipulomorpha is discussed with emphasis on the family Limoniidae. A negative reaction to the study by Petersen et al. (2010) is presented because they proposed an unusual phylogeny, with hardly acceptable classification. The family Limoniidae is here confirmed as monophyletic, divided into four clades classified as subfamilies (Starý 1992), with recent additional and reasonable changes. A revised phylogenetic arrangement of the family Limoniidae within Tipulomorpha is given.

Published: April 2021

Abstract
The purpose of this study was to assess a wide range of physiological and performance variables and investigate whether and to what extent these variables are associated with each other in soccer. Twenty-five male soccer players (25.1 ± 4.56 years; body mass, 75.2 ± 5.92 kg; body height, 180.6 ± 5.45 cm) performed: 5- and 30-m sprints (T5m and T30m, respectively), 1-repetition-maximum (1RM) half squat, maximal voluntary isometric contraction (MVIC) of the knee extensors, countermovement jump (CMJ) to obtain vertical jump height (CMJheight) and power output (CMJpower), the 10-s Wingate Anaerobic Test (WAnT) to obtain peak power (Pmax), and the 20-m multi-stage shuttle run test (MST) to evaluate aerobic capacity. 1RM, MVIC, and Pmax were normalized to body mass. Large negative correlations were found between sprint times and 1RM half back squat/BM (r = -0.510 to -0.570, r2 = 0.260–0.325, both p < 0.01) and Pmax/BM (r = -0.501, r2 = 0.251, p < 0.01). T30m most strongly and negatively correlated with CMJheight (r = -0.744, r2 = 0.554, p < 0.001). WAnT-determined Pmax showed a very large correlation between absolute Pmax and knee-extensor MVIC (r = 0.827, r2 = 0.684, p < 0.001) and large correlations between absolute Pmax and 1RM half squat (r = 0.674, r2 = 0.454, p < 0.001) and CMJpower (r = 0.579, r2 = 0.335, p < 0.01). We also identified a large inverse relationship between CMJheight and T30m (r = -0.744, r2 = 0.554, p < 0.001) and large positive correlation between CMJheight and MVIC/BM (r = 0.702, p < 0.001). The results demonstrate that elite soccer players with greater lower body strength (quantified by the MVIC of the knee extensor and the 1RM half squat) show better sprint and CMJ performance, suggesting the incorporation of soccer-specific resistance training to develop lower body musculature and therefore maximize sprinting ability. The higher correlation coefficients found between T30m and the physiological and athletic measures compared with T5m promote the use of this sprint distance when assessing performance. The use of relative measures (normalized to body mass) is advisable when comparing strength variables with sprint and CMJ performance or anaerobic power. Considering the correlations of WAnT-determined Pmax versus CMJpower, coaches should administer tests that assess jumping and linear sprint performance rather than the cycling-specific WAnT.
The Explanatory Capacity of Talent Identification Tests for Performance in Triathlon Competitions: A Longitudinal Analysis
Authors: Cuba-Dorado Alba , Garcia-Garcia Oscar , Morales-Sánchez Verónica , Hernández-Mendo Antonio 
Published: April 2021

Abstract
The aim of this study was to determine the explanatory capacity of the Spanish Triathlon Federation’s talent identification tests in relation to performance in competition in subsequent years. We used an exploratory longitudinal study design to establish the relationship between talent identification tests completed by 247 triathletes (97 women and 150 men) aged from 14 to 19 years and the results they obtained over the years in competition. The battery of tests included freestyle swimming (100 and 1000 m) and running (400 and 1000 m). The results indicate that the explanatory capacity of these tests for split places in competition in the corresponding discipline was highest in the 1000-m swimming test, with a value of 0.34 for the adjusted coefficient of determination (R2a) (p ≤ 0.001), followed by the 1000-m running and 100-m swimming tests, where the highest R2a values were 0.26 and 0.19, respectively. No significant model was found for the 400-m running test. It was concluded that the explanatory capacity of the tests analysed for predicting performance in the discipline in competition was low. However, it was higher for the swimming and running tests of longer distance.
Chitosan Improves Morphological and Physiological Attributes of Grapevines Under Deficit Irrigation Conditions
Authors: Khalil Hoda Ali , Badr Eldin Rasha M. 
Published: April 2021

Abstract
This study aimed to estimate the morphological and physiological effects of chitosan foliar spray and/or three irrigation levels of 100%, 60%, and 40% of field capacity on grapevines grown in plastic containers to simulate water shortage conditions. The results showed that water irrigation deficit significantly reduced leaf area, trunk cross-sectional area, plant dry weight, root dry weight, relative chlorophyll content, leaf total carbohydrates, catalase activity, leaf midday water potential (ψ), relative water content (RWC), and crop evapotranspiration (ETc), but increased the proline content. Under well-watered condition, foliar-applied chitosan, in particular, 5 and 10 g·dm−3 increased plant growth and biomass production compared with untreated plants. Also, chitosan sprays during deficit irrigation conditions significantly improved plant tolerance to water deficit by enhancing the morphological and physiological parameters of grapevines. The results of this work suggest the opportunity to grow grapevines under deficit irrigation conditions using chitosan foliar spray. Increased plant biomass and root weight, and the positive impacts of chitosan as antitranspirant on increased ψ, RWC, and decreased ETc play the main role in drought stress avoidance mechanisms in grapevines raised under moderate deficit irrigation conditions.
