For printing paper grades, runnability in the paper machine and in the printing press is partly attributed to the ability of the paper to tolerate flaws and defects in the paper. In these operations the paper fails due to forces applied in the plane of the sheet. It is important for the papermaker to have access to a relevant test method which can characterize those pulp properties applicable to this type of failure. Papermakers knew as early as the 1920’s that the strength of a cracked paper was a unique and useful paper property. This lead to the development of the out-of-plane tear strength test method. The tear test principle has, however, been criticized for many reasons. The most severe criticism lies in the mode in which the paper fails. The mode of fracture in most production and processing operations is seldom an out of-plane tearing, Mode III, but rather an in-plane crack propagation, Mode I.
Observation of Deforming and Fracturing Processes of Paper by Use of Thermography
Authors:   Department of Wood Science and Technology, Kyoto University, Yamauchi Tatsuo , Murakami Koji ,   Department of Wood Science and Technology, Kyoto University
Published: March 2024

Thermography has been found to be useful for detecting the local variations in temperature of paper sheet under strain. The changes in temperature images during the course of tensile straining could describe the local deforming and fracturing process of paper. A thermal deformation pattern of well formed paper was locally uneven, but uniform wholly throughout the specimen. On the other hand, the deformation pattern of poorly formed paper was uneven in micro and macro scale at the early stage of its plastic deformation region. However, the deformation pattern was fairly uniform through the specimen at the later stage of its plastic deformation.
Self-Ownership and Alienity of the World: Ontology of the Institution of Property in Modern Age
Authors:   Volgograd State Medical University, Seleznev Ilya
Published: March 2024

The work is devoted to the ontological foundations of the Western institution of property in the Modern Age. Philosophy plays a significant role in the project of the Modern Age to substantiate the natural, rather than religious, origins of property because it can provide rational legitimation for the institution. In this regard, to explicate the ontology of property in the Modern Age, the study turns mainly to two authors in whose texts such a discourse unfolds: John Locke and Karl Marx. John Locke, in his political philosophy, for the first time in the history of Western culture, derives the ownership of things from labor and explains the ownership of labor itself as the unconditional ownership of itself. Self-ownership implies a split into self-ownership and self-property while simultaneously identifying oneself, so the question of the meaning of self-ownership is raised. What ontology is based on this specific idea of the Modern Age about the natural belonging of a person to himself, and how does a man actually realize this belonging? Answers to these questions are given through an analysis of the early works by K. Marx, in which it is possible to explicate the ontology of self-ownership: it is thematized in the distinction between individual existence and the generic essence of man. Marx continues the division of men into themselves and themselves and proceeds from the fact that men as individuals initially belong to men as generic entities (which made possible Marx's statement that in the process of alienated labor, men are alienated from themselves). It is concluded that the ontology of self-ownership is rooted in the ontology of the subject of the Modern Age in general. Since only self-ownership is recognized as unconditional property in modern times, all things in the world appear in this ontology as initially alien and requiring appropriation in order to become one's own.
Historical Forms of Interpretation of the Modal Type of Integrity: The Heresy of the Monarchist Modalists and the Image of Holy Russia
Authors:   Volgograd State University, Tokareva Svetlana
Published: March 2024

The article considers two variants of interpretation of modal-type integralities. The first is represented by the heresy of the monarchists modalists and Savellians, which was widespread in the era of triadological disputes (the 3rd century). The denial by its representatives of the trinity of God and the recognition of the absolute identity of the natures of God, the Father and the Son, are considered not in the aspect of the history of triadological disputes but in the light of the interest of modern philosophy in the study of the modal type of integrity. The Sabellians make the definitions of God dependent on the ontological and anthropological conditions in which the experience of the epiphany and knowledge of God take place: God Himself determines His semantic aspects in each case, limiting Himself and setting the measure, form, and method of his manifestation in the world through revelation. The manifestations and definitions of God form a unity of a special type. Accordingly, statements about God necessarily turn out to be modal, since they speak of the Father, the Son, and the Holy Spirit not as coexisting and consubstantial divine personalities, but as three modes (consistently realized forms) of the manifestation of God as One. Using the example of the image of Holy Russia, it is shown that the use of a modal approach in relation to phenomena endowed with the status of the sacred has become entrenched in Christian culture. They are produced by religious consciousness as initial spiritual wholes, which, however, are not directly given but are revealed under certain conditions in historical reality through their many forms (modes). Each of the forms carries the "nature" or essence of the original integrity; however, in their real existence, these forms (modes), having a single source, are still separate entities with different functions and goals, with their own history, spatial location, time frames, etc. At the same time, the original integrity, manifesting itself in each of its modes, is not their summative unity and cannot be "assembled" from them as from parts.
Attitude to Heresy in the Light of Understanding the Church as an Anti-Polis
Authors:   Volgograd State University, Javorskiy Dmitriy
Published: March 2024

The article attempts to theoretically resolve the contradiction between negative and positive attitudes towards persecution in Christianity, a particular case of which is the persecution of heretics. The New Testament texts that constitute Christianity reveal grounds for both condemning and justifying persecution. Two ways of getting out of the indicated contradiction are critically considered. The first way is to distinguish between just and unjust persecution. It is shown that the Gospel contains a strong anti-persecution potential associated with the activities of Jesus Christ and, first of all, with his violent death. The asocial, escapist position of the supporters of the individualistic understanding of religious salvation is also criticized. As an alternative to both solutions, the author proposes an understanding of the Church as an anti-polis, that is, a social order that is not based on violence and ideological manipulation. The foundations of such an understanding are found in the "political philosophy" of the canonical gospels, where "magistrates and authorities" are associated with the figure of the "prince of this world" and, in turn, with the Devil or Satan, "murderer" and "father of lies". The gospel "political philosophy" opposes the power of the "prince of this world" with the ideal of the Kingdom of God, where people can coexist in love, that is, without violence and lies. This ideal was given to Christians not as a ready-made model along with an implementation algorithm but as a creative task. In this case, the social history of Christianity can be presented, on the one hand, as a search for the historical form of the Church as an anti-polis, and on the other hand, as a deviation from this ideal and the politicization of the Church. As a result, it is shown that in modern Christian thought, the question of the place of persecution in church life again becomes open, just as the question of attitude toward heresies turns out to be open: to perceive them as "waste products of dogmatic production" or as a valuable theological and philosophical heritage of the Christian tradition.

La masculinidad hegemónica ha influido a diferentes niveles y partes de la sociedad a través de la violencia que ejerce en el cuerpo de los mismos hombres, en cómo ven su cuerpo, cómo debe ser y hasta para qué lo deben utilizar y para qué no. Aunque el feminismo y la comunidad LGBTQ+ han investigado e influido para poner al descubierto temas como la masculinidad hegemónica, el patriarcado y las masculinidades alternativas, desde los hombres heterosexuales todavía hay acercamientos muy tímidos y nadie habla de lo que posiblemente muchos hombres quieran hablar y no se atreven. Por este motivo nacen las preguntas: ¿Qué es ser hombre? ¿Qué lo identifica como tal? Así que, esta investigación aborda estas y otras inquietudes alrededor de los hombres heterosexuales, para conocer cuál es su perspectiva, las diferencias y similitudes, que ayuden a poner sobre la mesa de diálogos sobre masculinidades, otra arista que permita aportar al entendimiento, aceptación y mejoramiento de la posición de muchos hombres que, probablemente, no se identifiquen con lo ya estudiado en Colombia. La temática se aborda desde las narrativas y las mediaciones comunicativas que tiene el cuerpo de los hombres, representadas desde la fotografía y diferentes instrumentos que aportan a la construcción de una propuesta para impactar positivamente a dicha población de Medellín.

Empowered Mini-Publics: A Shortcut or Democratically Legitimate?
Authors: Lee Shao Ming
Published: March 2024

Contemporary mini-publics involve randomly selected citizens deliberating and eventually tackling thorny issues. Yet, the usage of mini-publics in creating public policy has come under criticism, of which a more persuasive  strand  is  elucidated  by  eminent  philosopher  Cristina  Lafont,  who  argues  that  mini-publics  with  binding  decision-making  powers  (or  ‘empowered  mini-publics’)  are  an  undemocratic  ‘shortcut’  and  deliberative democrats thus cannot use empowered mini-publics for shaping public policies. This paper aims to serve as a nuanced defense of empowered mini-publics against Lafont’s claims. I argue against her  claims  by  explicating  how  participants  of  an  empowered  mini-public  remain  ordinary,  accountable,  and therefore connected to the broader public in a democratically legitimate manner. I further critique Lafont’s own proposals for non-empowered mini-publics and judicial review as failing to satisfy her own criteria for democratic legitimacy in a self-defeating manner and relying on a double standard. In doing so, I show how empowered mini-publics are not only democratic but can thus serve to expand democratic deliberation—a goal Lafont shares but relegates to non-empowered mini-publics.
Tudományos előmenetel a katonai pályán

Published: March 2024

A tudományos előmenetelre a katonai pályán – számos más tényező mellett – a nemzetközifolyóiratlisták változásai is hatást gyakorolnak. Mivel az egyéneknek ezekre nincs közvetlen befolyása, érdemes felkészülni rá, és olyan publikációs stratégiát kidolgozni, amely egyfelől a folyóiratok tudatos megválasztását jelenti, másfelől a kutatási és publikációsmódszerek nemzetközi sztenderdeknek való megfeleltetését, amely lehetővé teszi az ún. kvartilis lapokban történő megjelenést. Tanulmányunkban áttekintjük a tudományoselőmenetel kérdéseit katonai területen, a tudományos teljesítmény értékelését az akadémiaipályán, majd a nemzetközi publikációs listákon belül, a Magyar Tudományos Akadémia IX. Gazdaság- és Jogtudományok Osztálya, Hadtudományi Bizottságának folyóiratlistáját. Ezután statisztikai módszerekkel megvizsgáljuk a nemzetközi publikációs listaváltozásának feltételezett hatását a tudományos teljesítményre és az előmenetelre. Ennek oka, hogy egy-egy felülvizsgálat után egyes cikkek felkerülnek, mások azonban lekerülnek a nemzetközi listáról, ami befolyásolja a tudományos teljesítmény értékelését. Végül a vizsgálati eredmények alapján javaslatokat fogalmazunk meg az egyének és az intézmények számára egy tudatosabb publikációs gyakorlat kialakítására.

A characteristic, panduriform, large (ca 80 μm in length) diatom was sporadically detected in the Hungarian rivers in 2021 and 2022. Surirella tientsinensis Skvortzov emend. Liu was regarded as an Asian endemic species practically from its description until the second decade of the 21st century. Here we present the first Hungarian occurrence of the taxon from 2021, which is the second record for Europe, aft er the previously published Ukrainian data. In 2022 Surirella tientsinensis was detected from two other Hungarian river sampling localities. Due to the unmistakable outlook of the species, probably it is a new member of the Hungarian diatom flora, and its parallel occurrences in some localities within a short time, is noteworthy.

Floristical records of one fungus and ten flowering plants are presented from Hungary. We report a new occurrence of Calvatia candida in a valuable Pannonian sandy steppe habitat. Some of our floristical data present new occurrences of species that are rare in Hungary, but in the case of Orobanche minor, Minuartia viscosa, due to the low number of recent floristical data, we also try to clarify the distribution pattern of the species with data from specimens documented in the BP herbarium. The first occurrences of the rare, red-listed species Papaver hybridum was detected from the Duna-sík region. We report the first data of Orobanche minor from the Hungarian Middle Mountain Ranges, Minuartia viscosa is new for the southern part of the Mezőföld. A new record of Dactylorhiza sambucina from the Vértes Mts, which is in decline in our low-middle mountain areas, is published, an important observation from a conservation point of view. The data of Potentilla patula reported here is a new observation for the area of Cserhát-vidék. Our other data are from ruderal habitats, where we report observations of taxa that are mainly expanding but with few records in Hungary. The second Hungarian record of Senecio × helwingii is from the district of Zugló in Budapest. Erigeron sumatrensis has been found in several regions of Hungary, Euphorbia glyptosperma, Gypsophila perfoliata new occurrences were found in the border of Kecskemét. The recently suggested spreading of Medicago orbicularis is confirmed by new occurrence data from the Tihany Peninsula.
South African experiences in a restructured post-apocalyptic geo-political future as depicted in speculative fiction
Authors: Manase Irikidzayi
Published: March 2024

This article draws on science fiction's aesthetics of instability and multiple perspectives that disrupt the dominance of a Euro-American narrative voice (Langer 2011), as well as decolonial concepts such as coloniality, decentring and epistemic freedom (Ngügï 1986, 1992; Quijano 2007; Grosfoguel 2011; Ndlovu-Gatsheni 2018), to analyse the human condition and geopolitical patterns reflected in post-disaster worlds as depicted in Gillian Armstrong's "Elton" (2011), Abigail Godsell's (2011) "Taal" and Sarah Lotz's "Marine Drive, Durban Beachfront" (2014). The notion of multiple perspectives and contexts, and Smith's (2012) disruptive view that science fiction occurs everywhere, are used as lenses to examine the decolonised literary imagination. Ngügï argues (1986, 1992), that such an imagination moves the literary setting and vision from the Euro-American centre to another centre, in this case to a speculative post-apocalyptic South African future. The article argues that the depicted literary future and unfolding human experiences enable the constitution of decolonised literary imaginings and a cultural geography that restructure the current domination of geo-political and spatial mappings by the Global North. This restructured imagining places South Africa, and by extension Africa, at the centre of a speculative vision of humanity's sense of itself, knowledge production and agency, which are needed for the future survival of both the environment and other global inhabitants.

La economía globalizada plantea la necesidad de que las empresas cuenten con un lenguaje contable unificado que permita presentar información financiera comparable para la toma de decisiones. Es así como a nivel mundial se han adoptado las Normas Internacionales de Información Financiera (NIIF) para el registro y presentación de estados financieros. Ecuador aplica estas normas de forma obligatoria en 2010, según resolución No 08.G.DSC.010 de 2008.11.20, R.O.

Published: March 2024

Jelen kutatásban irodalmi feldolgozást nyújtottunk a közönséges gyertyánról, mely egy őshonos, számos kedvező tulajdonsággal is rendelkező, nem elhanyagolható fakitermelési lehetőséget nyújtó, de iparban kevésbé hasznosított fafaj. Megállapítottuk, hogy habár a faanyaga természetes formájában nem tartós, ugyanakkor az egyik legsűrűbb, legkeményebb, és legkopásállóbb fafaj Európában. Kedvezőtlen tulajdonságai miatt többnyire tűzifaként hasznosul. Beltéri felhasználási területeit új használati eszközökkel, burkolati elemekkel, és dekorációs elemekkel lehetne bővíteni, emellett különböző, környezetbarát famodifikációs eljárásokkal egy sokkal tartósabb és ellenállóbb faanyag kapható, melynek színét a kezelési beállítások variálásával alakíthatjuk a felhasználó igényeire. Ez az anyag felhasználható kültéri fatermékekhez, de akár építészeti célú alkalmazásra is. A gyertyán hazánkban középtávon stabilan rendelkezésre áll, és lehetőséget nyújthat tartós fatermékek előállítására, amennyiben meglenne rá a feldolgozó és a fizetőképes kereslet a hatékony szállítási távolságon belül. A kutatás végén a megállapításokat egy Gyengeségek-Erősségek-Lehetőségek-Veszélyek elemzéssel összegeztük.

A review on glaucoma: causes, symptoms, pathogenesis & treatment
Authors: Mahendra Kumar Sahu
Published: March 2024

If glaucoma is not treated, it can worsen and cause irreparable vision loss. It results from elevated intraocular pressure that gradually deteriorates the optic nerve. It is unclear exactly what causes this build-up of pressure, but several factors, including age, genetics, and specific medical disorders, may be involved. Glaucoma frequently has mild symptoms that take time to manifest and may not be apparent until considerable harm has already been done. Early detection and treatment can help prevent additional vision loss, which is why routine eye exams are so crucial. In order to reduce intraocular pressure, glaucoma is usually treated with medication or surgery. Eye drops, tablets, or a mix of the two can be prescribed. Traditional filtration surgery is one of the surgical options or more recently less invasive techniques. Glaucoma is a dangerous eye condition that needs to be closely watched over and managed. Although early diagnosis and therapy can help protect vision and prevent additional impairment, there is currently no treatment for the disease. People who are at elevated risk for glaucoma, including those who have a family history of the condition or who are older than 60, should make an appointment for regular checkups with an ophthalmologist to be checked for glaucoma symptoms. The article's summary will aid researchers in their efforts to improve glaucoma treatment.
Il processo decisionale condiviso nell’angina stabile
Authors: Cosmi Franco , Mariottoni Beatrice , Tarquini Barbara , Cosm Deborah
Published: March 2024

Nell’angina pectoris stabile la sintomatologia anginosa può essere controllata e la mortalità può essere ridotta dalla terapia farmacologica, dall’angioplastica o dalla rivascolarizzazione chirurgica. Il processo decisionale condiviso tra medico e paziente serve a ridurre ansia, paura, compassione ed ignoranza per lenire preoccupazioni e responsabilità che rischiano di portare le scelte al di fuori dei binari della scientificità, della reale efficacia, della sostenibilità economica ed ambientale. L’evidenza dello scienziato, l’esperienza del medico, la credenza del paziente e le concrete possibilità assistenziali sono i determinanti della scelta se non della cura migliore, almeno di quella più adatta. L’analisi di importanti studi come l’ARCA Registry, l’ORBITA 1 e 2 e l’ISCHEMIA e ISCHEMIA Extended consentono delle solide considerazioni. Nei pazienti con angina stabile senza anatomia coronarica sfavorevole la mortalità è sovrapponibile tra strategia invasiva e conservativa con importanti effetti collaterali maggiori più evidenti nella prima. La terapia farmacologica ottimale permette un controllo totale o parziale della sintomatologia nei 2/3 dei casi. Negli altri bisogna ricorrere alla rivascolarizzazione con angioplastica o chirurgia. In un quarto dei pazienti il dolore persiste nonostante la terapia anche combinata, probabilmente per i meccanismi vasomotori che accompagnano la patologia ostruttiva. Con il paziente vanno discusse le concrete possibilità assistenziali per la disponibilità farmacologica e per la terapia invasiva o chirurgica, considerata l’ampia variabilità degli esiti legata al volume di attività e alla gravità dei casi trattati nelle varie strutture operative. La probabilità condivisa dovrebbe rimpiazzare il consenso informato in una relazione medico-paziente centrale anche all’alba dell’“era della medicina metaclinica” per la soddisfazione di entrambi nella scelta delle evidenze migliori di una patologia diffusa e di elevato impatto emotivo, per evitare inutili paure, aspettative non realistiche, costi economici proibitivi ed impatti ambientali pericolosi.

This protocol is an update from the protocol described in the paper "Rapid and sensitive direct detection and identification of poliovirus from stool and environmental surveillance samples using nanopore sequencing" by Shaw et al in the Journal of Clinical Microbiology (2020), DOI: 10.1128/JCM.00920-20 and is commonly known as Direct Detection of Poliovirus by Nanopore Sequencing (DDNS). The protocol aims to amplify the VP1 region of poliovirus through a nested PCR using pan-Enterovirus (panEV) primers followed by amplification of the VP1 sequence using the Q8/Y7 primer set. We use barcoded primers as this greatly simplifies the subsequent library preparation process. Primer sequences for the barcoded Q8/Y7 primers are found in Dataset S1 of the publication. This protocol is for use with Oxford Nanopore kit14 chemistry sequencing reagents and can be used with the MinION Mk1B, MinION Mk1C, or GridION sequencer. Within the protocol steps, quality control checks are included and follow the workflow set out in the document "Quality Control and Data Recording for DDNS".
Differentiated Borders of Belonging and Exclusion: European Migrants in Rural Areas in Iceland
Authors: Skaptadóttir Unnur Dís , Wojtyńska Anna , Innes Pamela
Published: March 2024

This article addresses questions of difference, positionality, and belonging from the perspectives of international migrants living and working in rural communities in Iceland. With the recent integration of rural areas into the global economy, small villages and towns have undergone rapid social transformation. The development of new industries and growing tourism in these localities has attracted many international migrants. The share of migrants in the local populations oscillates between 10% to 50%, depending on the town, with the majority coming from Europe. Commonly, they make up the greater part of workers in service jobs and manual labour in rural towns and villages. This article builds on data from ethnographic field research over 15 months in five parts of Iceland located outside of the capital region. Based on the analysis of interviews with migrants, we examine different perceptions of affinity and belonging and explore their experiences of inclusion and exclusion. To what extent do migrants see themselves as part of local communities? How do they narrate their social positions in those places? The discussion highlights how social stratification and hierarchy affect migrants’ experiences of inclusion as commonly displayed in the interviews. Furthermore, we elaborate on how notions of relatedness and otherness reflect inherited ideas of Europe and contemporary divergent geopolitical positions.
Isparta kentinin doğal ve kültürel kimlik değerlerinin korunmasına yönelik irdeleme

Kentler toplumların yaşam biçimlerine ve bulundukları doğal çevre koşullara göre gelişen, geçmişten günümüze tarihin izlerini sürdüren, doğal ve kültürel kimlik değerlerine sahip mekanlardır. Ancak günümüzde küreselleşme, endüstrileşme ve hızla gelişen teknoloji ile sürekli değişime uğrayan kentler, kimlik değerlerini kaybederek birbirine benzeyen mekanlar haline gelmektedir. Bu nedenle kentlerin doğal ve kültürel tüm kimlik bileşeni unsurlarının ortaya konulması, kimlik değerlerinin sürdürülebilirliğinin sağlanması açısından büyük önem arz etmektedir. Isparta kent merkezi de pek çok kent gibi hızlı büyüme eğiliminde olduğu için içinde barındırdığı doğal ve kültürel değerleri tahrip olmakta ve yoksunlaşarak kaybolmaya yüz tutmaktadır. Bu çalışmada, Isparta kentinin kimlik değerlerinin sürdürülebilirliği açısından doğal ve kültürel envanter verileri çıkartılmış ve sayısal haritalar üzerinde bu değerler gösterilerek korunmasına yönelik mekânsal eylem önerileri geliştirilmiştir. Bu doğrultuda ArcGıs 10.6 yazılımı kullanılarak doğal ve kültürel kimlik değerlerinin sayısal veri altlığı oluşturulmuş ve günümüzdeki mevcut durum tespit edilmiştir. Isparta kentinin doğal ve kültürel kimlik değerlerinin korunmasına yönelik literatür değerlendirmeleri araştırılarak tartışmaya açılmıştır. Böylece, Isparta kent merkezinde bulunan doğal ve kültürel kimlik değerlerinin sürdürülebilirliğinin sağlanması için koruma kullanma dengesine yönelik mekânsal eylem önerileri çıkartılmıştır.

Authors: ALACALI Mine
Published: March 2024

Geothermal resources are often regarded as environmentally friendly and sustainable resources. They are utilized for different purposes, including energy generation, thermal tourism and greenhouse cultivation. The utilization type depends on the temperature, chemical characteristics and the flow rates of available geothermal resources. In long-term applications, there is a need for research and monitoring process to assess environmental consequences. Also, supervised use of the resource is crucial for both the geothermal system and its environment, as there is a possibility of unpleasant impacts on the environment, as chemical pollution, subsidence, and thermal effects in cases of improper use of geothermal resources. In Seferihisar, current consumption types of geothermal energy are consisting of a geothermal power plant with an installed capacity of 12 Mwe and a few primitive spas. In the Tuzla geothermal field, the geothermal waters ascending to the surface cause the deposition of travertine, where sea water interference to the geothermal system is clearly observed and supported by XRD analysis of the sample collected from the Tuzla travertine. Seismic activities as earthquakes, affect the surface manifestations of the SGS. The temperature measurement values obtained from Tuzla and Doğanbey are higher than the values recorded prior to the installation of the geothermal power plant. The operation of the geothermal power plant has caused the nearby hot springs to dry up and has ceased travertine deposition in the Cumalı geothermal field. The annual mean values of NO₂ and SO₂ for the region are lower than the National threshold value and European Union Countries’ threshold value.

Bu çalışmada, Çal (Denizli) bölgesinde iki farklı lokasyondan alınan kil bakımından zengin hammaddelerin mineralojik özelliklerinin belirlenmesi ve endüstriyel işlemlerle geleneksel seramik ürünlerin üretiminde kullanım potansiyellerinin ortaya koyulması, ayrıca arkeolojik seramik (çanak-çömlek vb.) hammaddesi olarak kullanılma potansiyelinin ortaya konması amaçlanmıştır. Bu kapsamda fiziksel, kimyasal (X-ışını floresansı, XRF), mineralojik (X-ışını kırınımı, XRD), termal analiz (Diferansiyel Termal Analizör-Termogravimetri, DTA-TG), kıvam limitleri ve tane boyu dağılımı analiz yöntemleri kullanılmıştır. Ayrıca, teknolojik testler için silindirik numuneler hazırlanıp 700°C'den 1100°C'ye pişirilmiş ve tüm sıcaklıklarda birim hacim ağırlığı, su emme, tek eksenli basınç dayanımı, boy kısalması ve hacimce büzülme değerleri ölçülmüştür. İncelenen killerin (ÇL4 ve ÇL5) kimyasal ve mineralojik bileşimlerinin incelenmesi sonucunda bileşimlerinde çok büyük farklılıkların olmadıkları tespit edilmiştir. Genel olarak kuvars, kalsit ve klorit mineralleri ile kil minerali olarak illit ve kaolinit içerdikleri, ÇL4 örneğinde ise farklı olarak klorit-simektit türü tabakalı killer tespit edilmiştir. Kimyasal olarak Çal killerinin ana oksitleri, SiO2, Al2O3 ve Fe2O3'ten oluşmakta olup ÇL4 örneğinde yüksek CaO ve kızdırma kaybı içeriğiyle karakterize edilmiştir. Fiziksel özellikleri açısından incelenen örnekler genellikle siltli kil olarak tanımlanmıştır. Plastisite indekslerinin (PI) %15-16 gibi yüksek bir değerde belirlenmesi, çalışılan killerin orta-yüksek plastik hammadde potansiyeline sahip olduğunu göstermektedir. ÇL4 örneğinin ÇL5 örneğine göre düşük birim hacim ağırlık ve daha yüksek su emme değerleri içerdikleri tespit edilmiştir. Tek eksenli basınç dayanımları ÇL5 örneklerinde kademeli olarak artış gösterdiği, ÇL4 örneğinde ise 800oC’den itibaren düşüş gösterdiği belirlenmiştir. Teknik testler, Çal killerinin tuğla ve kiremit gibi yapısal seramik ürünlerin imalatında ve ayrıca plastik killerin ilave edilmesi ile çanak-çömlek üretiminde uygun olduğunu göstermiştir.

A method of wireless measurement of blood flow parameters is investigated using an implantable passive capacitive sensor and an external reader. This device is designed to measure the parameters of blood flow in the human body, through the installation of a passive capacitive sensor and inductive coupling with an external reader device. The method of wireless measurement is based on the connection of resonant circuits at an operating frequency of 10 MHz. The mathematical calculation of the device circuit is presented. The result of the calculation was the dependence of the output voltage of the external reader on the change of capacitance in the implanted passive sensor. The values of the potential sensitivity of the device are obtained. The manufactured layout of the device and its parameters are presented. The mock-up allowed to investigate the dependences of the coupling factor of the circuits when using coils of an external reader of different sizes. Also the measurement of the output voltage of the external reader from the value of the passive sensor capacitance was made. The value of real sensitivity of the device layout was measured.

A method for estimating the transverse spin-Hall resistance for polycrystalline samples of pure metals has been proposed. The spin Hall effect coefficients for various metals of 3-6 periods, including rare-earth lanthanides, have been calculated. It is shown that the sign of the calculated spin-Hall resistance always coincides with the experimental one. For most of the considered metals the calculation result agrees with the experimental data. It is shown that the agreement of the calculation results with experiment can be significantly improved if the used approximations of strong coupling and effective charge are supplemented by the assumption that the interaction of collectivized conduction electrons in the construction of the self-consistent field can be taken into account by the introduction of the effective mass of the conduction electron in the Hamiltonian of the spin-orbit interaction. The reasons for the deviation for aluminum, copper, dysprosium, holmium, and gadolinium are discussed.

A sensor coating was created based on a Langmuir monolayer of 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE) with immobilized molecules of the enzyme glucose oxidase and its sensor properties were studied. The process of incorporation of glucose oxidase enzyme molecules into a Langmuir monolayer of phospholipid DPPE molecules was studied using the compression isotherm method. Adsorption of glucose oxidase molecules has an expanding effect on the Langmuir monolayer of DPPE and leads to an increase in the area per molecule from 32.5 Å2 to 49 Å2 and a decrease in the compression modulus of the monolayer from 133 mN/m to 83 mN/m. Also, the adsorption of glucose oxidase leads to an increase in the desorption coefficient of the monolayer into the kd subphase from 0.5·10-3 to 1.2·10-3. The morphology of films with immobilized enzyme molecules at different adsorption times was characterized by atomic force microscopy. Increasing the enzyme adsorption time leads to a decrease in the surface roughness of the formed film from 3.6 nm at 5 minutes to 2.4 nm at 60 minutes. The formed DPPE monolayers with immobilized enzyme molecules were transferred to graphite electrodes. Their sensory properties were studied using cyclic voltammetry and impedance measurements. The resulting coatings were sensitive to glucose in solutions with concentrations from 0 to 1 mg/ml. The presence of a linear concentration dependence of the maximum and minimum currents and resistances in the specified concentration range makes the created films promising for use as touch coatings.

Разработана оптимизированная конструкция спинтронного терагерцового излучателя, основанная на двухслойной структуре Co/Pt с интегрированным распределенным брэгговским отражателем. Внедрение брэгговского зеркала между структурой Co/Pt и кремниевой подложкой способствует повышению оптического поглощения в ферромагнитном слое, что усиливает генерацию спинового тока и, следовательно, ТГц сигнала. Для расчета оптического поглощения в ферромагнитном слое спинтронного излучателя была разработана модель, учитывающая параметры брэгговского зеркала (толщина слоев, период) на основе сверхрешеточной структуры [TiO2/SiO2]N. Модель основывается на решении уравнения Максвелла для электромагнитной волны в программном пакете COMSOL Multiphysics. Также было проанализировано влияние антиотражающих диэлектрических покрытий на уровень оптического поглощения в ферромагнитном слое. Исследование подтвердило, что применение оптимизированного брэгговского зеркала является достаточным для достижения оптимального поглощения.
