MODELOWANIE HAŁDY KRUSZYWA NATURALNEGO Z WYKORZYSTANIEM TECHNOLOGII UAV WRAZ Z ANALIZĄ DOKŁADNOŚCI
Authors: SMACZYŃSKI MACIEJ
Published: October 2021

The purpose of this article is to determine the potential of imaging obtained using an unmannedaerial platform (UAV) to create a digital model of terrain for aggregate heaps (DTMs). In addition, the intermediategoal is to carry out an independent accuracy check of the calculated 3D model, which in the study will be referred to an independent measurement using GNSS technology. The research object was a heap of natural aggregate with irregular shape and height differences up to 11 meters. Three point clouds with different detail parameters were generated from the acquired images. For further analysis, a point cloud with the best ratio of terrain reflection accuracy to the calculated RMSE value was selected. Independent control of 3D model accuracy was based on seven heap control points measured in the field and the same points generated on the 3D model . The deviations of several centimeters between field control points and points from the model may indicate the great potential of UAV technology and the possibility of its use in various engineering tasks.

A Parkia gigantocarpa pertencente ao grupo das espécies pioneiras e demandantes de luz, possuindo como principal característica ecológica o crescimento rápido, sendo indicada para plantio em clareiras e recomposição de áreas em projetos de restauração florestal. O objetivo desse estudo foi avaliar os efeitos de doses crescentes do fertilizante de liberação controlada (FLC) no desenvolvimento inicial de mudas de P. gigantocarpa. O estudo foi conduzido em casa de vegetação com 50% de sombreamento, por um período de 90 dias após o transplantio das mudas. Foi utilizado o delineamento inteiramente casualizado com quatro tratamentos e dezoito repetições. Os tratamentos consistiram em quatro doses de Osmocote® (0 - 4,1 - 8,2 e 12,3 g dm-3) na formulação NPK (15-09-12). Os resultados demostraram que a maioria dos parâmetros fitométricos e as trocas gasosas responderam de forma significativa para as doses intermediárias do FLC, podendo ser confirmados pelos aumentos em número de folhas (NF), área foliar (AF), massa seca total (MST), índice de qualidade de Dickson (IQD) e taxa fotossintética líquida (PN). Adicionalmente, também houve reduções significativas para a concentração intercelular de CO2 (Ci), demostrando que as mudas apresentaram maior eficiência estomática e no aparato fotossintético. Assim, o FLC contribuiu positivamente no crescimento inicial das mudas de P. gigantocarpa, sendo recomendado a dose de 4,1 g dm-3 do Osmocote®, 50% da dose recomenda pelo fabricante.

Chitinases are enzymes capable of hydrolysing the β-1,4 bonds of chitin releasing chitooligosaccharides and N-acetylglucosamine and are widely used in food, pharmaceutical, and agricultural industries. Microorganisms are potential producers of this enzyme; however, there are no reports in the literature on the production of chitinase by fungi of the genus Thermothelomyces. Thus, this work aimed to investigate the production of extracellular chitinase using alternative carbon sources by the fungus isolated from soil, Thermothelomyces heterothallicus PA2S4T. The fungus was cultivated in a liquid medium supplemented with carbon sources and incubated at 40°C under stationary conditions for seven days. Orange peel flour was the best inducer for extracellular chitinase, with 82.3 U/mL of enzymatic activity. The highest production of chitinase was obtained on the tenth day, and the optimum pH and temperature for enzyme activity were 4.5 and 50ºC, respectively. Therefore, the fungus T. heterothallicus PA2S4T proved to be promising in the production of extracellular chitinase, which presents pH and temperature characteristics favourable to biotechnological application.

Published: October 2021

O lixo plástico sofreu um aumento drástico e se tornou um dos maiores problemas ambientais do século XXI. A degradação térmica e catalítica de plásticos é uma das soluções viáveis para esse problema, pois pode conduzir tanto a benefícios de proteção ambiental, quanto para processos economicamente vantajosos em termos de gastos de energia. Neste trabalho, é apresentado um estudo termogravimétrico da conversão do polipropileno (PP) na presença de catalisadores mesoporosos AlMCM-48 (Si/Al=50 e 100). O desempenho catalítico mostrou que a reação de degradação do PP ocorreu em etapas de reações complexas nas taxas de aquecimento 5, 10 e 20 °C min-1. Além disso, o volume dos poros dos catalisadores nas diferentes razões molares Si/Al influenciou o processo de degradação em condições não isotérmicas e desempenhou um papel importante na diminuição da temperatura de degradação do PP. A energia de ativação aparente (Ea) foi determinada pelo método de isoconversão de Vyazovkin. Os parâmetros cinéticos obtidos revelaram uma redução na Ea evidenciando uma média de 89, 66 e 59 kJ mol-1 para a degradação do PP puro, PP + AlMCM-48(50) e PP + AlMCM-48(100), respectivamente. Como mostrado pelos valores médios, ficou evidenciado que a maior eficiência foi do AlMCM-48(100) que teve uma diminuição da energia de ativação de cerca de 30 kJ mol-1 em relação a energia de ativação do PP puro.

This study performed the phytochemical screening and bioactivity of Celosia argentea leaves. The phytochemical profile of hexane (Hex), ethyl acetate (AcOEt) and methanolic (MeOH) extracts of C. argentea leaves was observed by Thin Layer Chromatography and spectrophotometric analysis. In the susceptibility test, the disk-diffusion technique was performed. Minimum Inhibitory Concentration (MIC) was assessed by microdilution. Minimum Microbic Concentration (MMC) was determined in the extracts which presented MIC. Antioxidant activities were measured using 2,2-diphenyl-1-picril-hidrazil (DPPH), determination of reducing power and total antioxidant capacity (TAC). The results showed a higher content of phenolic compounds (252.02 ± 0.02 mg GAE/g) in the extract AcOEt, and of tannins (103.72 ± 0.004 mg/EAT/g) in MeOH; this was effective against Micrococcus luteus (inhibition of 24.7 ± 0.6 mm). MIC and CMM of the AcOEt for M. luteus were 0.06 and 0.25 mg/mL, respectively. The MeOH extract eliminated 70.4 ± 0.03% of DPPH radical, whereas AcOEt had greater reducing power (289.23 ± 0.05 mg AA/g) and TAC at a concentration of 250 µg/mL (89.6%). This study revealed that C. argentea has phytochemicals with bactericidal and fungicidal potential, in addition to elevated antioxidant power.

Trade, Exploitation, and the Problem of Unequal Opportunity Costs
Authors: Cassee Andreas
Published: October 2021

This paper assesses the ‘power-induced failure of reciprocity’ account of exploitation in the domain of trade. I argue that its proponents face a dilemma. Either the cost variable of reciprocity is understood to include opportunity costs. Then, the account implausibly implies that those with more valuable outside options should get a larger part of the overall benefits of cooperation. Or the cost variable is understood to exclude opportunity costs. Then, the account has awkward implications in cases where direct costs and opportunity costs are substitutable. To evade this dilemma, the account could be amended to include a hypothetical baseline that equalizes opportunity costs. But then, the account ceases to be isolationist. Whether a cooperative interaction counts as exploitative is no longer independent of moral considerations about distributions outside the domain of trade.
Múzeumra érzékenyítő képzés tanító és óvodapedagógus hallgatóknak a Hetedhét Játékmúzeumban
Authors: Nagy Veronika
Published: October 2021

A múzeumok komoly erőfeszítéseket tesznek azért, hogy közérthető módon szólaltassák meg a gyűjteményeiket, és a látogatók széles köréhez érjenek el. Érdekes, színes programokkal igyekeznek vonzóvá tenni a múzeumot, mint műfajt, és ezzel növelni a múzeumlátogató közönség számát. A múzeumlátogatói attitűd kialakításában kulcsszerepe lehet a játékmúzeumoknak, mert a tárgyuk, a témájuk a legközvetlenebbül érinti a gyermeket. A gyermek a játékon keresztül tanulja meg a világot, és a játékok segítségével lehet őt szocializálni a múzeumra is. A gyermek múzeumot értő és szerető gyermekké válik, ha a múzeumban folytatott játéktevékenységéhez pozitív érzelmek társulnak. Ehhez szilárd szakmai alapokon nyugvó múzeumpedagógiai programra van szükség, és arra, hogy az óvodapedagógusok már a képzésük során ismereteket szerezzenek a múzeumi tanulásról, a múzeumok, és különösen a játékmúzeumok pedagógiai hasznosíthatóságáról. A Hetedhét Játékmúzeum a Kulturális játszóterek – Óvodások fejlesztése játékmúzeumi módszerekkel című mintaprojekt megvalósítása óta (2017) elkötelezett a tanító és óvodapedagógus-hallgatók múzeumi érzékenyítése iránt. 2019-től Az ELTE-TÓK Neveléstudományi Tanszékén meghirdetett kurzusokhoz gyakorló terepet is biztosít, így a hallgatóknak lehetőségük van szervezett keretek között közvetlenül múzeumpedagógiai tapasztalatokat szerezni, és megismerni a játékmúzeumok nyújtotta lehetőségeket. A képzés célja, hogy a hallgatók figyelmét tudatosan irányítsa a múzeum felé, és megérintettségük eredményeként, a múzeumi foglalkozások alkalmával a jövőben tömegesen és „játszva” szocializálódjon múzeumra az óvodás és kisiskolás korosztály.
Participáció és közösségépítés. Gyakornoki program a Róth Miksa Emlékház és Gyűjteményben
Authors: Kolocz Dóra
Published: October 2021

2021 februárjában kezdődött el a Róth Miksa Emlékház és Gyűjtemény közösségi múzeumi projektje, amely új stratégia központi eleme a múzeum körül élő közösségek megszólítása, valamint új közösségek létrehozása. A fővárosi intézmény célkitűzései rezonálnak a múzeumot működtető VIII. kerületi önkormányzat terveivel is, amely egyezés, párhuzam jelentős lökést adott: intenzív változások indultak meg az intézményben. Az új irányvonal kijelölésével együtt kezdődött meg a múzeumi gyakornokok toborzása is, amely felhívás sikerének nyomán az intézmény szervezett, komplex gyakornoki programot tudott kiépíteni. A gyakornokok — egyebek mellett — részt vettek az új stratégia kialakításában, az intézmény teljes arculati megújításában, és munkát vállalnak a gyűjteményi és digitalizálási feladatokban is, miközben a gyakorlat mellett alapozó elméleti képzést is kapnak.

A gyakornoki program alapelve a participáció, azaz a „semmit róluk nélkülük“ elv, ugyanis a kiválasztott jelentkezők segítségével került kialakításra már maga a gyakornoki program keret- és elvárásrendszere is. A program nyomán fiatal szakmai réteg szerveződött az intézmény körül, amely célcsoport megszólítását és bevonását a múzeum egyik elsődleges feladatának is tekinti. A komplex program átlátható felépítéssel és transzparens működési célokkal folyik, miközben gyerekcipőben járó működési normáit és jellemzőit az intézmény a minőségmenedzsment feltételeinek kiépítésével igyekszik megőrizni, a rendszert pedig gördülékenyen működő, projektszemléletű múzeumi jelenséggé szervezni.
Vármúzeumok a pandémia alatt és után.
Authors: Gászné Bősz Bernadett , Schultz Éva
Published: October 2021

A várak a kulturális turizmus fontos vonzerői. Védett, történelmi épületeik számos kulturális és turisztikai funkciót egyesítenek, meghatározó közösségi terekként jelennek meg a helyi lakosság életében és mindezek révén a fenntartható turizmusfejlesztés koncepciójába jól illeszthető erőforrások. A várak örökség interpretációja kiemelt szerepet játszik a várlátogatók motivációiban. Az átélés a kulcsszó: a történelmi környezet magas élményígérettel bír és kiváló kulisszája a bevonódást segítő interpretációnak. Éppen ezért a COVID19 a vármúzeumokat az átlagosnál nehezebb feladat elé állította. Jelen kutatás célja a vármúzeumok pandémia okozta kihívásokra adott válaszainak feltárása mellett a keresleti reakciók felmérése volt. Hipotéziseink a következők voltak: H1: A vármúzeum látogatói élményét az online lehetőségek csak kis mértékben és csak speciális keresleti szegmensekben képesek helyettesíteni.

H2: A várak vonzereje számos tényező hatására felértékelődik a pandémia miatt az eddigi várlátogatók körében.

A vizsgálat egy korábbi, a dél-dunántúli várak látogatói élményére irányuló kutatás folytatásaként 2021 márciusában kvalitatív és kvantitatív eszközökkel történt. A kutatás eredményei igazolták a hipotéziseket. Az online térbe került kultúraközvetítés a dél-dunántúli várak esetében nem volt hatékony a látogatói vélemények tükrében. A várlátogatás az örökségi rendezvények kínálta közösségi élmény mellett a természeti környezet adta turisztikai lehetőségek miatt is vonzóbbá válik a közeljövőben. A kutatás eredményei hasznosíthatók a korlátozások feloldása utáni „újturizmusban” a várak menedzsmentjében, szakmai együttműködéseiben.

Obtaining Evidence for No Effect
Authors: Dienes Zoltan
Published: October 2021

Obtaining evidence that something does not exist requires knowing how big it would be were it to exist. Testing a theory that predicts an effect thus entails specifying the range of effect sizes consistent with the theory, in order to know when the evidence counts against the theory. Indeed, a theoretically relevant effect size must be specified for power calculations, equivalence testing, and Bayes factors in order that the inferential statistics test the theory. Specifying relevant effect sizes for power, or the equivalence region for equivalence testing, or the scale factor for Bayes factors, is necessary for many journal formats, such as registered reports, and should be necessary for all articles that use hypothesis testing. Yet there is little systematic advice on how to approach this problem. This article offers some principles and practical advice for specifying theoretically relevant effect sizes for hypothesis testing.

Restrictions during pandemic: justified but is it lawful?
Authors: Mažrimaitė Andra , Pasvenskas Vytautas
Published: October 2021

The article analyses if restrictions on business during the quarantines were proportionate and legitimate. The authors of this article argue that the forced closure of businesses during quarantine in its essence resembles the institute of taking private property ownership rights for public needs rather than restricting the freedom of economic activity because activities have been suspended entirely instead of merely being subject to certain operational restrictions. Such restrictions may be imposed only in exceptional cases and in the form of a law. It would be in line to consider proportionate compensations for businesses’ losses due to forcible closure from the State.

The research is mainly focused on taking legal regulatory measures that ensure the child’s rights to share information on the internet space, because the child is a vulnerable member of society. The current regulatory mechanism is not capable of protecting the rights of a child when his or her image is appropriate for promotional social networks. For this reason, the child may experience parental abuse of power, the child’s right to rest is not guaranteed, as well as the principle of separation of property.
Mythological Creatures in the Samogitian Daily Discourse of the 2nd Half of the 20th Century
Authors: Pajėdienė Jūratė
Published: October 2021

The article presents an overview of the contexts and functions of using the names of mythological creatures found in the Samogitian daily discourse of the second half of the twentieth century, paying attention to the dual – rational or subconscious – nature of naming a mythological creature. The overview is based on the material provided by the Samogitian dialect dictionaries (see Aleksandravičius 2011, Vanagienė 2014–2015) and by the collection of authentic Samogitian speech texts (see Girdenis 1996). Special attention is paid to the types of expressions formed with the name of the devil. In the Samogitian daily discourse the name of the devil (or the name of another mythological creature subordinate to the devil) is used not only in cursing but also to show one’s ignorance (the type of constructions ‘the devil knows what’ is very popular), to convey comparisons, epithets, to reinforce the meaning of certain words. The word vel’(n’)s ‘the devil’ and some of its synonyms are chosen as a distinctive, but quite common substitute for a personal name or are used as an address (addressing a person). Usually, such descriptions are related to a person’s energy and otherness or changes in his/her behaviour patterns.
Polish-language Threads in Lithuanian Healing Conjurations (Zagovory)
Authors: Vologdina Tatjana
Published: October 2021

Lithuanian conjurations (zagovory) constitute a unique part of Lithuanian folklore. In the collection of conjurations’ manuscripts described in the publication of Daiva Vaitkevičienė (2008), we will find records of these archaic texts in various languages, including Polish. Polish-language conjurations constitute a separate subgroup in the Balto-Slavic context. Following the chronological criterion, we are dealing with texts of pre-Christian and after-Christ origins. Due to mutual cultural influences as well as functioning of different languages within Lithuania, it is usually not possible to determine the original language of conjuration.Only in a few cases we are able to state, which version of conjuration is its translation. This is indicated primarily by the structure of the text as well as its lexical features, adaptation or transliteration.The article presents an attempt to compare Polish and Lithuanian texts, identify and analyze Polish language threads, their motives and subject matter as well as the ways in which such conjurations function.
On one extremal property of Korovkin's means

We point out that$$\inf\limits_{L \in L_n} \sup\limits_{\substack{f \in C_{2\pi}\\f \ne const}} \frac{\max \| f(x) - L(f, x) \|}{\omega^*_2(f, \pi/n + 1)} = \frac{1}{2}$$where $C_{2\pi}$ is the space of periodic continuous functions on real domain, $L_n$ is the set of linear operators that map $C_{2\pi}$ to the set of trigonometric polynomials of order no greater than $n$ ($n = 0,1,\ldots$), $\omega_2(f, t) = \sup\limits_{x, |h| \leqslant t} |f(x-h) - 2f(x) + f(x+h)|$, $\omega^*_2(f, t)$ is the concave hull of the function $\omega_2(f, t)$. In this equality, the infimum is attained for Korovkin's means.

On some properties of normally-inflective complexes with simple inflective center in $E_3$
Authors: Ishchenko Ye.N.
Published: October 2021

In the paper, we consider the special degenerate class of mormally-inflective complexes with simple inflective center in three-dimensional Euclidean space $E_3$. We prove that to construct this class of complexes one should take an arbitrary curve and draw sheaf of straight lines through each point of this curve. For arbitrary normally-inflective complex with simple inflective center we establish that such complex is fibered into two one-parametric families of congruences.

Strategic Challenges to Internationalization in Higher Education in a Times of Crisis
Authors: Blagoeva Elena
Published: October 2021

The article analyzes the impact of the Covid crisis on the processes of internationalization in higher education institutions, the subsequent reactions and possible management approaches to restore the stability of international activities. The growing interest of European universities, including Bulgarian ones, in implementing an international dimension in higher education has led to a significant commitment of their missions to the concept of internationalization over the last 20 years. But after the beginning of the Covid crisis, there was a stagnation of almost all internationalization processes, especially the mobility of students for periods of study or obtaining a degree. Analyzing the causes and obstacles to mobility, it is clear that in the next few years the situation will be similar. The need for the right strategy and optimal allocation of resources to rebuild internationalization processes, along with all other changes related to the Covid crisis, is not an easy task for universities. They must not only strive to ensure high-quality teaching and learning, but also to develop innovative forms of teaching - motivating, effective, competitive, guaranteeing access to the labor market. This task will require a lot of imagination, creativity and ingenuity from the academic community and from decision makers. But universities need to put in the necessary effort and resources, as students' motivation has not changed - international exposure and education open up a variety of opportunities for young people; provide them with exciting experiences; encourage understanding, sharing of ideas; increase cultural competencies. And, ultimately, build them as stronger individuals and citizens of the world. At the moment, these values are even more important for the future.

Authors: Krasnov Viktor V. , Pimenov Danila A. , Sedov Valery I. , Kotova Vera N. , Pavlovich Lilia R.
Published: October 2021

There is a hypothesis among the scientists that COVID-19 and SARS-CoV-2 have negative effect on the immune system. Many reports on multisystem inflammatory syndrome (MIS) development after COVID-19 are published worldwide. Whereas, the impact of this infection on prevalence and course of any other infectious diseases has not been studied. The aim of the study is to draw attention to the estimation of other infectious diseases course after COVID-19 by analyzing the clinical case of pneumococcal septicemia in 17 years old boy who has undergone COVID-19. We obtained data about COVID-19 during the analysis of the child's medical history. The course of infectious process was similar to the course of multisystem inflammatory syndrome in children (MIS-C), compared by clinical manifestations. The results of ELISA blood assay have proved it: we revealed IgG to SARS-CoV-2. However, PCR test revealed S. pneumoniae DNA in blood, so MIS-C diagnosis was excluded. The role of SARS-CoV-2 in other diseases in postcovid period can not be excluded, and it requires further studies. Development of screening and rehabilitation principles is recommended despite the severity of COVID-19 in children.

Effect of on-farm trials in popularization of rice variety NDLR-7 (Nandyal Sona) in Chittoor district of Andhra Pradesh
Authors: Kumar P. Ganesh , Lakshmi R. Prasanna , Subramanyam D.
Published: October 2021

Rice crop is grown in 43934 ha in Chittoor district of Andhra Pradesh during Kharif and Rabi. The traditional medium slender grain cultivar BPT-5204 is most popularly grown variety during Kharif and occupies 30-40 per cent of area in the district, which is susceptible to BPH and blast resulting in low yields and low net returns. Hence, on farm trials were conducted during 2012-13, 2013- 14 and 2014-15 with objective to assess the performance of new rice variety NDLR-7 which is medium slender short duration (130-135d) variety with tolerance to BPH and blast. During all the three years maximum number of BPH/sample was very low in NDLR-7 than BPT 5204 and maximum collections were recorded in November followed by October month. During all the years the variety recorded 6.1t/ha with average net returns of Rs.76,808/- per ha whereas BPT-5204 recorded 5.83t/ha with average net returns of Rs.68,542/ha. Because of its high yield, pest tolerance and good cooking quality it is widely accepted by farmers through horizontal spread of technology. Due to extension activities of KVK, Kalikiri area under NDLR-7 has been increased from 80ha in 2013-14 to 2000 ha in 2016-17 owing to its tolerance to BPH, fine grain and high market price and first choice of farmers, millers and traders.

Authors: Helen S. , Mridula N.
Published: October 2021

A study was conducted among 150 agricultural extension personnel from five districts of Kerala to identify the constraints faced by the agricultural extension personnel in using information and communication technologies (ICTs) in transfer of technology and suggested strategies for their capacity building. Lack of proper training facility was recorded as the most experienced constraint with a mean score value of 9.48, followed by inadequate computer facility (8.82) available to them. The other major constraints experienced by the extension personnel were poor technical know how and conducting trainings at inappropriate times with a mean score of 8.32 each and lack of financial resources formain taining the ICT tools with the mean score of 8.03. It is suggested to categorise the extension personnel into two groups viz., those extension personnel who need the basics of ICTs and those extension personnel who require the knowledge on advanced ICTs. Target specific training modules, hands on experience, well established infrastructure, adequate funds and personnel for repair and maintenance, computer based trainings and advanced circulation of annual training calendars among extension personnel by the training organizations are the suggested strategies for the capacity building of extension personnel of Kerala in using ICTs.

Small and marginal farmer do not have economic strength to adopt advanced production technologies, services and marketing including processing and value addition. Through formation of FPCs farmers will have better collective strength for better access to quality input, technology, credit and better marketing access through economies of scale for better realization of income. Therefore, during lockdown period online study was under taken to measure knowledge level of KVK Subject Matter Specialist (Extension Education), KVK SMS of other disciplines, stake holders from NABARD and ATMA (MACP). Knowledge test was administered to the 65 respondent in the Google form, which has reduced influence of interviewers and ease of filling the interview schedule. A total 65 respondents were selected and a knowledge test consisting of 17 dimensions was prepared to measure their knowledge level. The study revealed that majority of the respondents had awareness regarding farmers producer company’s profit sharing, followed by company registration under companies act, information about ownership and management as a share holders and priority sector for formation of farmers producer company’s. It is also found that respondent had poor knowledge about processing, marketing, branding of produce by FPC, benefits of formation of FPCs, followed by implanting agencies for FPCs and financial sustainability of FPCs. Categorization of respondents based on their knowledge level indicate that majority of respondent were in high level of knowledge i.e. 41.53 per cent respondent have high level of knowledge followed by 32.30 per cent in medium level while 26.15 per cent low level of knowledge category. In order to enhance farmers income and empowers small and marginal farmers promotions of farmers producer company has intervention for agril. entrepreneurship development.
