Infectious diseases can be transmitted from one person to another or from animals to humans of the causes of infection diseases is fungi. Fungi are microorganisms in the form of cells or branched threads. These microorganisms have a rigid cell wall and  composed of polysaccharides or chitin, have nuclei and spores, are not chlorophyllous and do not multiply sexually and asexually. Based on this, research was carried using of the welling method on antifungal bioactivity as well as a thin layer chromatography test of spotting to determine the content of secondary metabolites contained in the leaves of kale fence. This study aims to determine the bioactivity of secondary metabolites in n-hexane extract, ethyl acetate, and methanol of kangkong pagar leaves (Ipomoea carnea Jacq) against Candida albicans fungi. This study made four different concentrations namely 60%, 80%, 100%, 120%, for positive control using ketoconazole and negative control using CMC 1%. Data analysis is using the One Way ANOVA test. From this study, the results were that kale fence leaf extract contains secondary metabolites, namely flavonoids, tannins, steroids. Then the results of the antifungal activity test of fencing kale leaves have activities that can inhibit fungi at a concentration of 120% with an inhibitory zone diameter of 11,254 mm so that they can be classified as strong antifungal bioactivity, in the results of the One Way ANOVA analysis of the three samples (N Hexana, Methanol and ethyl Acetate), it is known that the Sig value is 0.000 < 0.05 so it can be said that the rata_rata is "Significantly Different".

Authors:   Vyatka State University, Kirov, Russia, Lesnykh Nadezhda Yu. , Sozinova Anastasia A. ,   Vyatka State University, Kirov, Russia
Published: February 2023

In 2022 The Global Risks Report of the World Economic Forum (WEF) indicated the main global risks, for example, environmental and socio-economic problems. Experts have recognized that the “green” model of the economy, which is now beginning to be actively applied in the energy sector, has the potential to counteract these risks. The authors of the article propose a transition to a “green” economic model not only in the energy sector, but also in the service sector, for example, in the tourism. The concept of “green” model of tourism is considered as a conscious model of long-term industry’s development, based on ESG principles (responsible attitude to the environment, high social responsibility, high quality of corporate governance).

МЕТОДИ ПІДВИЩЕННЯ ПРИХОВАНОСТІ ПЕРЕДАВАННЯ ІНФОРМАЦІЇ НА ОСНОВІ РОЗШИРЕННЯ СПЕКТРА ТАЙМЕРНИХ СИГНАЛІВ
Authors: Корчинський В.В. , Назаренко О.А. , Степанов В.О. , Аль-Файюми Халед
Published: February 2023

У статті розглянуто методи розширення спектра таймерних сигнальних конструкцій. Для систем радіозв'язку, що працюють в умовах радіоелектронного конфлікту, пропонується використовувати шумоподібні таймерні сигнали. Це дозволяє підвищити інформаційну, структурну та енергетичну прихованість сигнальних конструкцій. Проведено аналіз властивостей таймерних сигнальних конструкцій, що дає змогу виявити певні переваги непозиційних сигналів перед позиційними. Структурна прихованість таймерних сигналів залежить від параметрів пристрою кодування. Також таймерні сигнали можна використовувати як завадостійкий код, для якого не потрібні додаткові перевірочні елементи. За рахунок зміни параметрів побудови таймерних сигналів існує можливість змінювати коригувальну здатність коду, а також формувати різні ансамблі сигнальних конструкцій. Це потенційно збільшує структурну та інформаційну прихованість таймерних сигналів. Енергетична прихованість досягається за допомогою різних методів розширення спектра бінарного сигналу: псевдовипадкового перескоку робочої частоти; прямого розширення спектра псевдовипадковими послідовностями; лінійної частотної модуляції. Однак розвиток радіотехнічних засобів перехоплення широкосмугових сигналів потребує також ускладнення структури сигнальних конструкцій. Використання таймерних сигналів дає можливість синтезувати більш складні шумоподібні сигнальні конструкції. Це дозволить підвищити структурну прихованість та ускладнить розкриття структури сигналу засобами радіотехнічної розвідки супротивника. Таким чином, обґрунтованим є розробка та вдосконалення методів розширення спектра таймерних сигналів. Однак методи розширення спектра сигналів розроблялися виключно для позиційних кодів, тому не можуть бути застосовані до таймерних непозиційних сигналів. Наукові роботи, які присвячені дослідженню шумоподібних таймерних сигналів, не повною мірою висвітлюють алгоритми перетворення вузькосмугового сигналу на широкосмуговий. Це стало приводом для подальшого дослідження в цьому напрямку, тому метою цієї роботи є синтез шумоподібних таймерних сигнальних конструкцій.

Brain abscesses caused by anaerobic microorganisms: a systematic review
Authors: Cobo Fernando
Published: February 2023

The objective of this study was to perform a systematic review of the characteristics, causative microorganisms and outcome of brain abscesses caused by anaerobic bacteria over the past 25 years. We reviewed studies on brain abscesses which included infection due to anaerobic microorganisms published between 1998 and 2022. We excluded reports with polymicrobial infections (more than 2 anaerobic bacteria isolated) and those that do not provide enough information to make comparisons, the reports with only one case of brain abscess due to anaerobes, as well as those focused on an only anaerobic bacterium. Also, we have excluded the cases in pediatric population. We searched the scientific literature through the Cochrane Library, EMBASE and PubMed/MEDLINE databases for studies of this condition. We finally included 28 studies with 6,167 patients, of which 715 (11.5%) were cases caused by anaerobic bacteria. There was a male predominance (70%) and mean age of 40.3 years. Most infections were monomicrobial (59.4%). The most common anaerobic microorganisms isolated were Bacteroides spp (43.4%) and Gram-positive anaerobic cocci (35.1%). Cases of brain abscesses caused by anaerobic bacteria were most frequent in Asia and Europe. The source of infection most frequent was otogenic in 84.6% followed by a neurosurgery procedure infection in 23% of patients. The main symptom observed was headache in 95.6% of patients followed by fever (69.5%). Surgical treatment was performed in 48 % of patients and the percentage of patients in whom antibiotic treatment was applied range 88.8% to 100%. The main limitation of this review is the non-inclusion of studies published before of 1998 in which MALDI-TOF MS system had not been introduced in the majority of laboratories for routine identification. The patient rate with isolation of anaerobic bacteria in brain abscesses is low, but these data could be underestimated mainly due to the fastidious nature of these microorganisms and the difficulties in the identification of some anaerobes.
Building Information Modeling (BIM) and Robotic Manufacturing Technological Interoperability in Construction – A Cyclic Systematic Literature Review
Authors: Anane Walid , Iordanova Ivanka , Ouellet-Plamondon Claudiane
Published: February 2023

The architectural engineering and construction (AEC) industry is undergoing a digital transformation that progressively improves its performance, productivity, and competitiveness. This digital shift is accelerated through building information modeling (BIM) which facilitates technological integrations. BIM has significantly contributed to digitizing design and management activities. However, it has not yet sufficiently demonstrated its interoperability with digital manufacturing processes, such as robotic manufacturing (RM). It is from this perspective that this work will review the current literature’s stance on the technological interoperability of BIM and RM tools through the systematic literature review (SLR) method. This literature review aims to identify research avenues to operationalize RM through BIM tools in construction. The study conducted in this research is progressive; it builds on the identified research gaps and investigates potential research avenues to be undertaken. The results revealed that computational design (CD) could serve as a bridge between BIM and RM. They also revealed that RM is operationalizable in off-site construction (OSC) through BIM and CD.
Events in the Age of Heightened Vulnerabilities: Towards Pragmatic Hoping
Authors: Pernecky Tomas , Faisal Abrar
Published: February 2023

This thought piece seeks to address the following question: How can we respond to the challenges and opportunities in contemporary eventscapes in meaningful, ethically rich, and enduring ways? By considering the intersections of risk, crisis, resilience, and creativity, the notion of
"pragmatic hope" emerges as the capacity to navigate the ever-changing risk environment and the ability to act in ethical, imaginative, creative, and practical ways through the medium of events. The article highlights that considerations around risk and resilience have surfaced to the forefront
of event decision-making processes and argues that creativity is increasingly bound up with wider societal, moral, ecological, and socioeconomic conundrums. An agency-based view of events phenomena is suggested, with events contemplated as the extension and expression of "we."

Badano zdolność kombinacyjną zróżnicowanych komponentów matecznych oraz komponentów ojcowskich wytworzonych w programach hodowli mieszańców żyta. Komponenty rodzicielskie tworzonych mieszańców żyta zostały wyhodowane w firmach hodowlanych: Danko Hodowla Roślin Sp. z o.o., Poznańska Hodowla Roślin Sp. z o.o. i Hodowla Roślin Smolice Sp. z o. o. Krzyżowanie 29 męskosterylnych mieszańców pojedynczych (CMS-SC) z trzema populacjami przywracającymi płodność (Syn-R) wykonano w układzie czynnikowym na polach przestrzennie izolowanych. W okresie wegetacji 2012/2013 oceniono ogółem 87 mieszańców F1 typu CMS-SC×Syn-R w trzech doświadczeniach polowych, które zostały założone metodą bloków niekompletnych w 3 miejscowościach i w 3 powtórzeniach. Wielkość poletka wynosiła 5 m2, a gęstość siewu 250 kiełkujących ziaren/m2. Analizowano następujące cechy: plon ziarna, masa 1000 ziaren, wysokość roślin, termin kłoszenia, intensywność pylenia, porażenie rdzą brunatną i mączniakiem, stopień wylegania. Obliczenia statystyczne wykonano za pomocą programów komputerowych SERGEN i EKSPLAN. Przeprowadzono analizę wariancji zdolności kombinacyjnej, oszacowano efekty ogólnej zdolności kombinacyjnej rodziców (GCA) i swoistej zdolności kombinacyjnej par rodzicielskich (SCA) oraz ich współdziałanie ze środowiskiem. Analiza wariancji wykazała istotne zróżnicowanie mieszańców pod względem wszystkich cech agronomicznych. Stwierdzono istotną zmienność ogólnej zdolności kombinacyjnej komponentów matecznych i ojcowskich dla większości cech. Zmienność swoistej zdolności kombinacyjnej okazała się istotna głównie dla wysokości roślin, intensywności pylenia i masy 1000 ziaren. Oszacowano wielkość i istotność średnich efektów GCA komponentów matecznych i ojcowskich. Ponadto testowano istotność interakcji GCA komponentów matecznych i ojcowskich ze środowiskiem. Wyodrębniono komponenty mateczne i ojcowskie o wysokiej i stabilnej ogólnej zdolności kombinacyjnej plonu i innych cech agronomicznych, które mogą być wykorzystane w programach hodowli odmian mieszańcowych żyta.

Morfologia i anatomia systemu korzeniowego nowych odmian ziemniaka. Część I. Morfologia systemu korzeniowego
Authors: Rykaczewska Krystyna
Published: February 2023

Celem pracy była ocena zmienności morfologii system korzeniowego 17 odmian ziemniaka i rozważenie ewentualnego związku z tolerancją na wysoką temperaturę i suszę w okresie wegetacji. Badania przeprowadzono w szklarni w roku 2014. Wśród wyselekcjonowanych do badań odmian ‘Tetyda’ była tolerancyjna i ‘Aruba’ wrażliwa na stres abiotyczny. Do badań systemu korzeniowego zostało wykorzystane urządzenie do aeroponicznej produkcji minibulw ziemniaka umieszczone w hali wegetacyjnej. Pomiary przeprowadzono w czasie kwitnienia roślin, czyli na początku ich tuberyzacji. Stwierdzono istotne różnice między odmianami pod względem głębokości zasięgu korzeni, ich świeżej i suchej masy oraz zawartości suchej masy w korzeniach. Maksymalny zasięg korzeni osiągał wartość 109 cm. Był on pozytywnie skorelowany ze świeżą masą korzeni. Miarą wielkości systemu korzeniowego roślin ziemniaka stosowaną przez większość badaczy jest sucha masa korzeni. W naszych badaniach wahała się od 0,93 do 4,78 g na roślinę zależnie od odmiany i była wysoce istotnie skorelowana z długością łodyg i masą części nadziemnej roślin. Zawartość suchej masy w korzeniach wynosiła od 4,4% u odmiany Miłek do 7,6% u odmiany Tetyda, o wysokiej tolerancji na stres abiotyczny w okresie wegetacji. Jednak wykazanie zależności między tolerancją odmian na stres wysokiej temperatury i suszy w okresie wegetacji a suchą masą korzeni będzie wymagało dalszych badań.

W latach 2013–2015 prowadzono badania związane z oceną zawartości chlorofilu u ekotypów i odmian prosa rózgowatego (Panicum virgatum L.), w warunkach zróżnicowanego nawożenia. W trzech fazach rozwoju roślin: kłoszenie, kwitnienie oraz dojrzewanie nasion, oznaczano wskaźnik zawartości chlorofilu (CCI — Chlorophyll Content Index). Zastosowano jednorazowe nawożenie mineralne nawozem Polifoska M, w następujących dawkach: I blok — bez nawożenia, II blok — 20 kg Mg /ha, III blok — 40 kg Mg /ha. Przeprowadzone analizy składu chemicznego prób glebowych w latach 2013–2015 wykazały bardzo niską zawartość magnezu (28 – 30 mg/l gleby). Dla obiektów, w każdym bloku nawozowym, wykonywano po 5 pomiarów zawartości chlorofilu w liściu podflagowym w danej fazie rozwojowej. U badanych ekotypów i odmian prosa rózgowatego zaobserwowano zróżnicowanie wskaźnika zawartości chlorofilu niezależnie od stosowanej dawki nawozowej. Najwyższe wartości wskaźnika zawartości chlorofilu (CCI) odnotowano w fazie kłoszenia i kwitnienia. Największą zawartością chlorofilu charakteryzowały się obiekty prosa rózgowatego nr 1, 2, 3 i odmiana Dacotah. U obiektu Panicum virgatum nr 2 i 4 i odmiany Dacotah zaobserwowano wpływ nawożenia na wartości CCI zarówno w fazie kłoszenia, jak i kwitnienia, natomiast u obiektu nr 3, odmiany Summer tylko w fazie kłoszenia, a u ekotypu nr 1 w fazie kwitnienia. Wykazano pozytywny wpływ nawożenia magnezowego na zawartość chlorofilu u badanych obiektów prosa rózgowatego.
Unemployment, Effects of Government Measures and Employment Effects During the
Corona Crisis in Germany
Authors: Steyer Katrin
Published: February 2023

During the corona pandemic, policymakers in Germany had to act swiftly. There were
targeted corona aid and programmes. The impact of the programmes on the development of
unemployment is the subject of research, especially in German-speaking countries. There
are gaps in knowledge regarding the impact of the pandemic on gender unemployment. By
analysing the research in a structured way and combining it with the analysis of
unemployment data, it is shown that the Corona measures helped prevent unemployment. It
also shows that women were more affected by unemployment. The increased risk of becoming
unemployed is followed by a higher risk of remaining unemployed for longer. Studies show
that women are significantly more affected by this risk than in previous recessions. The
results indicate that women are more likely to be unemployed for longer due to their
desire to work in sectors that are typical for women. Considering the shortage of
skilled labour is a prevalent issue, the author proposes targeted policy advice to bring
women out of unemployment without stereotypes.

Authors: Johnsundarsingh Arul Jose , Thangasa Sree Renga Raja
Published: February 2023

The application of Ceiba Pentandra Oil is introduced as an alternative to the traditional non-biodegradable insulation oil. Through the recent research in vegetable based insulation oil (coconut oil, palm oil, and olive oil), it is identified that the vegetable insulation oil is biodegradable but edible in nature, which leads to the food crisis. To prevent the insufficiency of food, an interesting non-edible oil is extracted from the seeds of Ceiba Pentandra, which has the capability of biodegradation. This work has focused on the utilization of Ceiba Pentandra seeds for the production of vegetable based insulation oil since it is considered as the sustainable energy resource and. A two-step chemical conditioning method and antioxidants are used to produce the Processed Ceiba Pentandra oil (PCPO). Adding to that, the insulation behavior of Processed Ceiba Pentandra oil (PCPO) with and without antioxidant is analyzed. The different concentrations of PCPO and naphthalene based Mineral oil mixtures have been compared as per the ASTM standard. The two-step chemical conditioning method has provided the enhanced behavior of physical properties like Viscosity, Acidity, Flashpoint, Fire points and AC breakdown voltage. While improving the oxidation stability, the electrical property like AC Breakdown voltage has met the dielectric Standards. Thus this Processed Ceiba Pentandra oil (PCPO) has the potential to be an alternative of traditional insulation oil.

Graphite-based graphene oxide (GO) and coal-based graphene oxide (GO/SiO2, which we call graphene oxide/SiO2 because the surface of the resulting coal-based GO is linked with SiO2 from the coal structure) were prepared by the conventional Hummers oxidation method and ultrasound-assisted Hummers oxidation method, respectively, using natural graphite powder and Xinjiang Wucaiwan coal as carbon sources. Furthermore, the structures of the two were studied comparatively. Afterwards, the two lamellar structure products were hydrophilically modified with octadecylamine and dicyclohexylcarbodiimide by a hydrothermal method. And then, added these products (graphite-based GO-ODA and coal-based GO/SiO2-ODA) to No.32 cycloalkyl base oils in order to comparatively investigated their tribological properties as lubricant additives. The results showed that the dispersion stability of coal-based GO/SiO2 in the lubricant was significantly better than that of graphite-based GO; meanwhile, the tribological performance of GO/SiO2-ODA in the lubricant better than that of graphite-based GO-ODA due to the surface linkage of coal-based GO/SiO2 with SiO2 particles. After 1 h - long grinding in a four-ball friction test, the lubricant friction coefficient of 0.03 wt% coal-based GO/SiO2-ODA oil reached a minimum of 0.118, which reduced 58.1% compared to pure base oil and reduced 2.8 times compared to the counterpart using graphite-based GO-ODA under the same experimental conditions.

The sources of Islamic law are anything that gives birth to legal provisions governing Muslims. It has been agreed by scholars that the Qur’an is the main source of law for Muslims, the next is hadith / sunnah, and ijma'. The Qur’an is an aggregate of all rules in any situation and condition for mankind. All aspects of human life are in it. Muhammad, PBUH. as an apostle and mukzijat al-Qur’an given the privilege to explain in detail things that are still general in the Qur’an. His explanation was not just utterance, but also inscribed with real deeds with full obedience. The words and deeds of the Messenger of Allah which are called hadiths clarify Islamic law, so that people who have faith will easily obey God's commands. As caliph on earth, humans are required to observe the commands contained in the two main sources of Islamic law, namely the Qur’an and the hadith. If there is no clear information about the latest issue in both, then the Qur’an and the hadith itself instruct the scholars to devote their thoughts to establishing the law, and the result of the accuracy is called ijma'. Thus ijma’ can be used as the third source of Islamic law. hence the Qur’an and the hadith itself which instruct the scholars to devote their thoughts to establishing the law, and the result of which is called ijma'. Thus ijma’ can be used as the third source of Islamic law, hence the Qur’an and the hadith itself which instruct the scholars to devote their thoughts to establishing the law, and the result of which is called ijma'. Thus ijma' can be used as the third source of Islamic law. This study uses a qualitative descriptive method with the type of research used is library research. The purpose of this research is that the reader knows the urgency of understanding the sources of Islamic law about al-Qur’an, Sunnah, and Ijma' and its comprehensive implementation, so that readers cannatural daily life can be motivated to practice religion according to its rules and find Islam to be a dynamic, humanist, elastic, and egalitarian religion as well as compatible (shalihun li kulliz zaman wal makan).
HAK DAN KEWAJIBAN PEREMPUAN DALAM PERSPEKTIF SYARIAT ISLAM
Authors: Asman Asman
Published: February 2023

Islam has its own views regarding women's equality. For example, it can be seen from the more prudent and far-sighted Islamic efforts to strive for women's equality on the one hand without eliminating that womanly nature on the other. Islamic society in this and other problems, is subject to what has been stipulated by Islamic law. Based on the above problems, what needs to be studied in this paper is how women are in the perspective of Islamic law, as the main study is the source of the law, rights and obligations of women in Islamic law. This study uses a literature approach that discusses relevant books on feminism and is filtered in Islamic law or sharia. This study concludes that in relation to the rights that women have, having a special responsibility to be implemented is not the same as that of men.
How to construct liquid-crystal spectacles to control vision of real-world objects and environments
Authors: Gomez Michael A. , Snow Jacqueline C.
Published: February 2023

A major challenge in studying naturalistic vision lies in controlling stimulus and scene viewing time. This is especially the case for studies using real-world objects as stimuli (rather than computerized images) because real objects cannot be “onset” and “offset” in the same way that images can be. Since the late 1980s, one solution to this problem has been to have the observer wear electro-optic spectacles with computer-controlled liquid-crystal lenses that switch between transparent (“open”) and translucent (“closed”) states. Unfortunately, the commercially available glasses (PLATO Visual Occlusion Spectacles) command a high price tag, the hardware is fragile, and the glasses cannot be customized. This led us to explore how to manufacture liquid-crystal occlusion glasses in our own laboratory. Here, we share the products of our work by providing step-by-step instructions for researchers to design, build, operate, and test liquid-crystal glasses for use in experimental contexts. The glasses can be assembled with minimal technical knowledge using readily available components, and they can be customized for different populations and applications. The glasses are robust, and they can be produced at a fraction of the cost of commercial alternatives. Tests of reliability and temporal accuracy show that the performance of our laboratory prototype was comparable to that of the PLATO glasses. We discuss the results of our work with respect to implications for promoting rigor and reproducibility, potential use cases, comparisons with other liquid-crystal shutter glasses, and how users can find information regarding future updates and developments.
O ensino de argumentação na Argentina e no Brasil: aproximações e distanciamentos em diretrizes curriculares
Authors: Alves Lima Sheyla Fabricia , Batista Santos Yuri Andrei
Published: February 2023

Considerando a demanda pela universalização da educação escolar nos países da região sul-americana, este trabalho tem por objetivo discutir como as diretrizes curriculares, na Argentina e no Brasil, propõem o desenvolvimento da argumentação no componente Língua Materna.

Delineamos, então, uma análise de discursos comparativa que observa como cada cultura discursiva em destaque desenvolve suas percepções quanto ao ensino de argumentação. Nosso corpus centra-se nos eixos de trabalho com linguagens nos documentos de diretrizes curriculares para o ensino médio na Argentina, Núcleos de Aprendizagen Prioritarios, e no Brasil, Base Nacional Comum Curricular.

Observamos que os discursos relacionados ao ensino de argumentação sugerem algumas aproximações quanto à ausência de uma base teórica para pensar o desenvolvimento desse conhecimento. Tal lacuna desdobra-se em semelhantes distanciamentos, no que tange à ausência de um ensino de argumentação concreto que ultrapasse as conformidades do desempenho em exames e avaliações externas.
