Handedness and Musicality in Secondary School Students
Authors: Anstee Lottie , Müllensiefen Daniel , Harrison Peter
Published: June 2023

This article investigates the relationship between handedness and abilities in secondary school students, specifically analyzing the effect of handedness on subjective and objective musicality and academic performance. Previous research on the association between handedness and musicality has yielded mixed conclusions. Some studies have documented a positive correlation between musicality and non-right-handedness, but other studies have found no relationship. Here we aim to address some of this uncertainty, using a greater diversity of relevant covariates and a considerably larger sample than previous research. Our dataset of 2,902 participants (age range 10–18) comes from the LongGold project: an international longitudinal study of educational development in secondary school students. Musicality was measured through a self-report questionnaire (Gold-MSI) and perceptual tests; academic ability was determined using a Matrix Reasoning test and school grades. Using regression analyses, our main result is a lack of relationship between musicality and handedness, both for self-reported musicality and objective perceptual ability. In contrast, we found a significant association between right-handedness and higher academic ability. Our results provide a clearer perspective on the nature of handedness and its relationship to abilities, as well as highlighting changing dexterity as an area for future research.
The Physiology of Musical Preference
Authors: Mehdizadeh Sophia Kaltsouni , Leslie Grace
Published: June 2023

The dominant research strategy within the field of music perception and cognition has typically involved new data collection and primary analysis techniques. As a result, numerous information-rich yet underexplored datasets exist in publicly accessible online repositories. In this paper we contribute two secondary analysis methodologies to overcome two common challenges in working with previously collected data: lack of participant stimulus ratings and lack of physiological baseline recordings. Specifically, we focus on methodologies that unlock previously unexplored musical preference questions. Preferred music plays important roles in our personal, social, and emotional well-being, and is capable of inducing emotions that result in psychophysiological responses. Therefore, we select the Study Forrest dataset “auditory perception” extension as a case study, which provides physiological and self-report demographics data for participants (N = 20) listening to clips from different musical genres. In Method 1, we quantitatively model self-report genre preferences using the MUSIC five-factor model: a tool recognized for genre-free characterization of musical preferences. In Method 2, we calculate synthetic baselines for each participant, allowing us to compare physiological responses (pulse and respiration) across individuals. With these methods, we uncover average changes in breathing rate as high as 4.8%, which correlate with musical genres in this dataset (p < .001). High-level musical characteristics from the MUSIC model (mellowness and intensity) further reveal a linear breathing rate trend among genres (p < .001). Although no causation can be inferred given the nature of the analysis, the significant results obtained demonstrate the potential for previous datasets to be more productively harnessed for novel research.
Hydropower Plant Construction and Resettlement in Nghệ An, Vietnam
Authors: Thi Do Nhinh , Casse Thorkil , Gverdtsiteli Gvantsa , Hyakumura Kimihiko
Published: June 2023

The global challenge of moving toward a low-carbon energy system heightens the tension between states’ economic development efforts and environmental concerns. In Vietnam, increasing energy demand has led to a boom in hydropower development in recent decades. For local communities, dam construction has brought displacement, involuntary resettlement, deteriorating income and living standards, and rising poverty. However, from the central government’s perspective, the negative local impacts of hydropower projects are negligible compared to their national benefits. This study uses the construction of the Bản Vẽ hydropower plant to illustrate how government entities expand their control of villagers’ livelihoods in the name of environmentalism. Spanning nearly twenty years, our case study reports on changes in the Vietnamese approach to authoritarian environmentalism. The authorities initially promoted voluntary relocation with a brochure depicting the high quality of resettlement areas. When the remaining locals hesitated, because they had heard that the promised new homes had various problems, the authorities forced them to move.

Overall, the case study shows the Vietnamese authorities deploying different instruments to implement their will, engaging in little meaningful dialogue with local people. Moreover, when locals sought alternative income from acacia plantations, the authorities cited environmental concerns to justify confiscating their forest holdings.
Populismo, un concepto y una palabra controvertida
Authors: Ahedo Unai
Published: June 2023

Populismo es una palabra ambigua y confusa, que genera un ardoroso debate como concepto, pero, también como término. En este artículo nuestra pretensión es la de profundizar en el status controvertido del populismo como elemento integrante del vocabulario de las ciencias sociales. En primer lugar, profundizaremos en las problemáticas y ambigüedades que surgen de su uso común, de su uso banal, de su uso en la pugna política y partidista diaria. En segundo lugar, indagaremos en los obstáculos que se nos plantean en su uso especializado o académico. Por un lado, debido a la fragmentación y escasa acumulabilidad de las teorías existentes. Y, por otro lado, debido a la extendida práctica de creación de neologismos y el empleo de sinónimos que encajen con el significado que se otorga al fenómeno populista. Este repaso por lo problemático del populismo nos situará inmediatamente en el debate sobre su validez y utilidad como categoría analítica de las ciencias sociales. Una discusión que nos situará ante la disyuntiva de desterrar el término del vocabulario científico o proseguir en la tarea de encontrar algún tipo de definición. En definitiva, en la compresión del complejo e intricado fenómeno populista.
Profiles and categorisation of perceptions and attitudes among European citizens regarding the just energy transition
Authors: García-García Pablo
Published: June 2023

Just energy transitions have re-emerged from their unionist roots to gain increasing momentum politically and scholarly, especially driven by the SDGs. In the movement from unionism to mainstream debate, the notion has acquired diverse nuances that determine its normative scope. Four major approaches have been theoretically proposed to classify views currently: statu quo, managerial, structural, and transformative. Implicitly, these approaches observe two dimensions: individualism versus collectivism, and green growth versus post-growth. Although this classification has been useful to study the positions of groups of individuals in international organisations, NGOs, and activist movements, this paper suggests testing if it remains operative in contrast with individuals’ attitudes and perceptions. Through basic statistics, clustering algorithms, and correspondence analysis applied to the most recent version of the European Social Survey (2020-2022), this contribution finds three key insights. First, although the empirical four-group classification resembles some of the theoretical traits, it does not fit the approaches. The individualism versus collectivism dimension is operational, but the environmental dimension is difficult to determine. Second, empirically, twenty-three optimal groups exist. Three groups congregate more than 90% of respondents. The remaining marginal but optimal groups point to the relevance of observing isolated profiles in the study and political planning of just energy transitions. Finally, human values show greater explanatory capacity than sociodemographic and political variables.

Published: June 2023

Este libro presenta los resultados del proyecto de investigación “Diversidad religiosa y arquitectura en Colombia”, realizado por los grupos de investigación “Sagrado y Profano” (UIS) y Ginvearqui (USTA), con el apoyo financiero de la Vicerrectoría de Investigación y Extensión de la Universidad Industrial de Santander, la Unidad de Investigación e Información y la Oficina de Dirección de Relaciones Internacionales - DRI- de la Universidad Santo Tomás, Bucaramanga. Hace un análisis socio-arquitectónico a 15 lugares de culto representativos de grupos religiosos significativos en Colombia. Se analizan variables que interrelacionan el espacio sagrado con las representaciones y expresiones religiosas. Se busca responder a preguntas, tales como: .Cuál es la configuración de los espacios encargados de acoger las diversas prácticas religiosas?; .cómo se sacraliza el espacio?; .qué elementos físicos o fenomenológicos caracterizan esos espacios y se encargan o no de aportar cargas simbólicas al objeto arquitectónico?; .cuál es la relación existente entre corrientes interreligiosas y el diseno y uso de estos espacios?; .en qué medida los espacios sagrados influyen en el entorno? La respuesta a estas preguntas nos llevó a comprender la estrecha relación existente, en la mayor parte de los casos, entre práctica o ritual y arquitectura o espacio y todo ello, en relación con el entorno.
A vueltas con la teoría de la «democratización» del más allá tras el Reino Antiguo. Algunas ideas
Authors: Cervelló Autori Josep
Published: June 2023

La teoría de la «democratización» del más allá tras la caída del Reino Antiguo y de la oposición entre los destinos de ultratumba de los reyes y de los particulares en la Edad de las Pirámides fue enunciada a comienzos del siglo XX y ha permanecido incuestionada hasta hace pocos años. Recientemente, en efecto, esta teoría ha sido objeto de una profunda revisión crítica sobre la base de dos argumentos esenciales: a) el ritual de las ofrendas de reyes y de particulares en el Reino Antiguo es sustancialmente el mismo, tal como se desprende de los Textos de las pirámides regios y de los textos e iconografía de las tumbas privadas; b) Los Textos de las pirámides del Reino Antiguo y los Textos de los ataúdes del Reino Medio constituyen, en realidad, un único corpus: si los segundos son claramente textos al alcance de los particulares, los primeros también lo serían, aunque a nosotros nos haya llegado solo su versión regia. Todo esto significaría que no hay oposición entre el más allá de reyes y de particulares en el Reino Antiguo. En este artículo proponemos una revisión de la antigua teoría a la luz de una discusión de los términos de esta crítica.Palabras clave: Religión egipcia. Creencias funerarias. Ritual funerario. Textos funerarios. Textos de las pirámides. Reino Antiguo. Teoría historiográfica.AbstractThe theory of the «democratization» of the beyond after the fall of the Old Kingdom and the opposition between royal and non-royal afterlife destinies in the Pyramid Age was enunciated at the beginning of the XXth century and has remained unchallenged until a few years ago. Recently, indeed, this theory has been the subject of a thorough critical review based on two main arguments: a) the offering ritual of royal and non-royal persons in the Old Kingdom is substantially the same, as it appears from the royal Pyramid Texts and from the texts and the iconography of the private tombs; b) The Pyramid Texts of the Old Kingdom and the Coffin Texts of the Middle Kingdom actually are a single corpus: if the latter are clearly texts accessible to non-royal persons, the former had to be accessible to these people as well, though only their royal version has come up to us. All this would mean that there is no opposition between royal and nonroyal beyond in the Old Kingdom. In this paper we propose a review of the ancient theory by discussing the terms of this critical approach.Keywords: Egyptian religion. Funerary beliefs. Funerary ritual. Funerary texts.

Bringing treasures and placing fears: Old Kingdom epithets and titles related to activities abroad
Authors: Diego Espinel Andrés
Published: June 2023

AbstractThe present study analyses two epithets related to the Egyptian activities abroad: “who brings the produce from the foreign countries” (inn(.w) xr(y.w)t m xAs.wt) and its variants, and “who places the fear of Horus in the foreign countries” (dd(.w) nrw Hrw m xAs.wt). As with other Old Kingdom epithets, they have generally been overlooked as informative data on the administrative roles and vital experiences of their holders. In order to evaluate their potential significance as sources of information, both expressions are brought into connection with the titles of their holders and related biographical accounts. As a result, the epithets become complementary data that help to profile the actual functions and actions of these officials. For the sake of completion, certain titles related to the acquisition of intelligence are also included in this study. Moreover, further thoughts on the possible origins and values of Old Kingdom epithets are also presentedKeywords: Epithets, Ancient Egypt, Old Kingdom, intelligence, foreign policy, inter-regional trade, diplomacy, administration.ResumenEl presente trabajo estudia dos epítetos asociados a las actividades egipcias en el extranjero: “quien trae los productos de las tierras extranjeras” (inn(.w) xr(y.w)t m xAs.wt) y otras expresiones similares, y “quien pone el terror que inspira Horus en las tierras extranjeras” (dd(.w) nrw Hrw m xAs.wt). Como notros epítetos del Reino Antiguo, éstos han sido habitualmente infravalorados como información efectiva sobre las funciones administrativas y las vivencias de quienes los detentaron. Para valorar su posible importancia como fuentes de información, ambos epítetos se han estudiado junto con los títulos y textos biográficos de sus poseedores. El resultado es que ambas expresiones son relevantes para entender y precisar mejor las responsabilidades y acciones de dichos oficiales en el extranjero. En aras de una mayor exhaustividad, también se analizan algunos títulos relacionados con el servicio de inteligencia durante este período. Por último, se presentan algunas reflexiones sobre los posibles orígenes y significados de los epítetos durante el Reino Antiguo.Palabras clave: Epítetos, Egipto antiguo, Reino Antiguo, servicio de inteligencia, política exterior, comercio exterior, diplomacia, administración.
Tras las huellas del príncipe Ahmose-Sapair

Published: June 2023

El príncipe Ahmose-Sapair debió fallecer en torno al año 1550 a. C., y poco tiempo después comenzó a ser venerado y luego percibido como un miembro memorable de la familia real en Tebas durante cinco siglos. Mientras que su parentesco, recuerdo y culto ha sido objeto de estudio por diferentes autores, la cuestión de la posible ubicación de su tumba no ha sido nunca tratada en profundidad, a pesar de ser un aspecto relevante de su veneración postuma. El presente artículo aborda esta cuestión, revisando la documentación de excavaciones anteriores y a la luz de los recientes hallazgos realizados por la misión arqueológica española que excava en Dra Abu el-Naga, al suroeste del patio de entrada a la tumba-capilla de Djehuty (TT 11).Palabras clave: Ahmose-sapair; necrópolis; Dra Abu el-Naga; antigua Tebas; EgiptoAbstractPrince Ahmose-Sapair passed away around 155O BC. He was worshipped soon after his death and was regarded as a memorable member of the royal family in Thebes for around five centuries. While his ancestry, remembrance and worship have been the subject of several studies, the location of his tomb has not been discussed in depth, despite the fact that it appears to be a significant aspect in his posthumous cult. This matter is hereby addressed, re-examining the data from earlier excavations and in the light of recent discoveries made by the Spanish mission working in Dra Abu el-Naga North, southwest of the open courtyard of the tomb-chapel of Djehuty (TT 11).Keywords: Ahmose-Sapair; necropolis; Dra Abu el-Naga; ancient Thebes; Egypt
In vulneratis libris memoriam et reditus asservare. Notas sobre la biblioteca perdida del monasterio de Villanueva de Oscos
Authors: Carrasco Lazareno María Teresa
Published: June 2023

El monasterio asturiano de Santa María de Villanueva de Oscos, vinculado al Císter desde 1203, contó con una notable biblioteca conocida a través de varios inventarios elaborados entre fines del siglo XVI y la primera mitad del siglo XIX, que se conservan en el Archivo Histórico Nacional de Madrid. De la biblioteca medieval sólo quedan, al presente, algunos “testigos” aislados, membra disiecta y fragmentos de viejos códices de pergamino. Los libros caídos en desuso, volúmenes rotos y maltratados, se reutilizaron para encuadernar otros libros de archivo y proteger documentos en la Edad Moderna. Estos fragmentos procedentes de códices pregóticos son elocuente sobre tales prácticas archivísticas, al tiempo que nos proporcionan los primeros indicios para “reconstruir” la biblioteca perdida de la abadía de Oscos.Palabras clave: Asturias, Villanueva de Oscos, monasterio cisterciense, archivo monástico, biblioteca, códice pregótico, fragmentos y membra disiecta, Biblia, breviario, textos hagiográficos, siglo XIII.AbstractThe monastery of Santa María de Villanueva de Oscos in Asturias, affiliated to the Cistercian order in 1203, had a large library known through several inventories made between the Late Sixteenth Century and the first half of the Nineteenth Century, that are kept in the National Archives in Madrid. At present, there are only some isolated “witnesses” of this ancient library, i.e. membra disiecta and fragments of old parchment manuscripts. The obsolete books, broken and ill-treated volumes were used to bind other archive books or to protect documents in the Modern Age. These fragments from pre-Gothic codices show such archival practices while providing some clues “to reconstruct” the lost library of the Abbey of Oscos.Keywords: Asturias, Villanueva de Oscos, Cistercian monastery, monastic archive, library, pre-Gothic codex, fragments and membra disiecta, Bible, breviary, hagiographic texts, Thirteenth Century.

Presiones estadounidenses a la cooperación tecnológica con China: el caso del sector nuclear de Argentina
Authors: Blinder Daniel , Vila Seoane Maximiliano
Published: June 2023

En el marco de un contexto internacional en transformación, donde las disputas geopolíticas entre grandes potencias se han acentuado, la literatura de Relaciones Internacionales ha prestado creciente atención al rol de la ciencia y la tecnología. La mayoría de esta literatura examina las capacidades de los países centrales en su carrera por dominar tecnologías estratégicas y/o emergentes, con especial énfasis en la creciente rivalidad entre China y EEUU. No obstante, la literatura le ha prestado menos atención a cómo esta competencia por la supremacía tecnológica incide en las estrategias de adquisición de capacidades y/o de desarrollo tecnológico de países de menores recursos. El presente trabajo tiene como objetivo conceptualizar las presiones internacionales realizadas por un estado sobre otro estado, para que no obtenga ni desarrolle capacidades tecnológicas transferidas por otro estado, sea este rival o no lo sea. En particular, se sostiene que las presiones internacionales contra la cooperación científico-tecnológica suelen involucrar una mezcla de uso de encuadres coercitivos, engaño, hostigamiento diplomático, diplomacia pública mediada, y sanciones, pero muchas veces el efecto de las presiones internacionales puede ser limitado. Para ilustrar esta propuesta conceptual, se analiza el caso de las presiones de EEUU sobre Argentina para evitar la construcción de una planta nuclear de diseño chino, denominada Hualong One o HPR1000. El estudio de caso se basa en el análisis cualitativo de fuentes primarias, como documentos oficiales y entrevistas semiestructuradas, y de otras fuentes secundarias pertinentes. Específicamente, el estudio sintetiza la cooperación nuclear entre Argentina y China entre 2012-2022, y detalla las presiones estadounidenses realizadas durante la administración Macri (2015-2019) y la administración Fernández (2019-2022). El análisis de este caso ilustra la conceptualización de presiones internacionales propuesta, en particular, los datos recabados muestran que las presiones estadounidenses contra la cooperación nuclear entre Argentina y China fueron realizadas por intermedio de hostigamiento diplomático, encuadre engañoso, y diplomacia pública mediada. Estas presiones han tenido el propósito de acabar con la cooperación en temas que son de interés para EEUU. No obstante, si el objetivo de máxima de la diplomacia estadounidense fue propiciar la cancelación del proyecto, las presiones parecen no haber sido exitosas. Sin embargo, si suponemos que buscaron retrasarlo, en tal caso, dado que desde el inicio de las negociaciones en 2012, aún no se ha iniciado la planta nuclear, se puede suponer que fueron un factor que incidió en esta demora.

Szczepienia u kobiet ciężarnych – przegląd aktualnych zaleceń
Authors: Surowiec Monika , Kędzierska Mirosława , Sikora Agnieszka
Published: June 2023

Szczepienia chronią kobiety ciężarne przed zachorowaniem na choroby zakaźne, a dzięki przenoszeniu przez łożysko specyficznych przeciwciał w klasie IgG oraz przeciwciał przenoszonych z mlekiem matki (IgA, IgG i IgM) zapewniają ochronę niemowlętom już od pierwszych dni życia. Szczepionka jest preparatem, który stymuluje układ odpornościowy do odpowiedzi, jaką uzyskuje organizm przy kontakcie z drobnoustrojem chorobotwórczym. W czasie ciąży większość szczepionek jest bezpieczna, z wyjątkiem szczepionek żywych (atenuowanych). Szczepionkami zalecanymi dla kobiet w ciąży są szczepionki przeciw krztuścowi, przeciw grypie oraz przeciw SARS-CoV-2. Noworodki i niemowlęta należą do grupy szczególnie narażonej na choroby zakaźne, dlatego też zapobieganie zakażeniom poprzez zastosowanie szczepień ochronnych u kobiet ciężarnych stanowi podstawę profilaktyki.
Metody nośnikowe w ocenie działania wirusobójczego środków do dezynfekcji powierzchni i do dezynfekcji narzędzi – ujęcie praktyczne
Authors: Trzcińska Agnieszka , Duszak Emilia
Published: June 2023

Dezynfekcja powierzchni często dotykanych przez pacjentów i personel medyczny odgrywa istotną rolę w zapobieganiu i kontroli rozprzestrzeniania się wirusów w placówkach opieki zdrowotnej (szpitalach, przychodniach, gabinetach dentystycznych), a także w czasie opieki nad pacjentem, m.in. w gabinetach lekarskich/dentystycznych, w szkole, żłobkach, przedszkolach, domach opieki oraz w domu. Również w przypadku niektórych narzędzi zabiegowych wielokrotnego użycia stosowana jest dezynfekcja chemiczna, ponieważ sterylizacja termiczna może prowadzić do korozji narzędzi, a ograniczenia czasowe nie pozwalają na przeprowadzenie sterylizacji termicznej w przypadku zabiegów w terenie. Produkty do dezynfekcji powierzchni oraz środki do dezynfekcji narzędzi muszą charakteryzować się określonymi cechami, w tym posiadać szeroki zakres aktywności uwzględniający bakterie, w tym prątki, wirusy, grzyby, potwierdzony badaniami wykonanymi metodami opisanym np. w obowiązujących normach fazy 2/etapu 1 oraz fazy 2/etapu 2. Cel Celem badań była praktyczna ocena metod nośnikowych w aspekcie badania produktów do dezynfekcji powierzchni oraz produktów do dezynfekcji narzędzi, m.in. w ocenie wpływu czasu suszenia zawiesiny wirusa na nośniku na stabilność miana zakaźnego wirusów, wpływu zastosowanej metody na parametry odzysku wirusa. Materiał i metody W badaniu porównano miano dla wirusów testowych określone w metodzie zawiesinowej i po wysuszeniu wirusów na nośniku (w czasie maks. 60 min.) i ich odzysku do podłoża hodowlanego. Wyniki i wnioski W większości przypadków (mysi norowirus, wirus krowianki) miana uzyskiwane dla wirusów testowych wysuszonych na nośniku szklanym lub stalowym w badaniu nie różniły się między sobą o więcej niż o 0,5 log. Na przykładzie wirusa adeno i wirusa krowianki sprawdzono, czy wydłużenie czasu suszenia wirusa na wybranym nośniku ma znaczący wpływ na obniżenie miana wirusa. W przypadku obu badanych wirusów żaden z zastosowanych czasów inkubacji zawiesiny wirusowej w temperaturze pokojowej nie spowodował wyższej niż 0,38 log (wirus adeno) oraz 0,25 log (wirus krowianki) redukcji miana zakaźnego w stosunku do kontroli określanej w czasie „0”. Potwierdzono również, że najwyższym współczynnikiem odzysku charakteryzuje się metoda z użyciem szklanych kulek o średnicy 3–4 mm.

Published: June 2023

Ionic liquids that dissolve cellulose provide an option to pretreat lignocellulosic biomass. In this study, potential application of three ionic liquids in pretreating rice husk and their abilities in dissolving rice husk cellulose were investigated. The ionic liquids applied were 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc), and 1-ethyl-3-methylimidazolium diethyl phosphate ([EMIM]DEP). Dissolution of rice husk was conducted by heating 1.5% (w/v) rice husk-ionic liquid mixture at 100oC for 20 hours. The dissolved cellulose was subsequently regenerated with deionised water. All the ionic liquids were able to dissolve rice husk cellulose to varying extents, with the highest dissolution (36.7%) given by [EMIM]OAc followed by [BMIM]Cl (31.3%) and [EMIM]DEP (16.0%) at the 10th hour of heating. All the regenerated cellulose were found to be more amorphous as compared to the untreated rice husk. The energy study showed that both [EMIM]OAc and [BMIM]Cl had lower energy requirement compared to [EMIM]DEP. The results of energy requirement complemented the findings of dissolution ability of the ionic liquid. Both [EMIM]OAc and [BMIM]Cl are potential ionic liquids to be used in the pretreatment of rice husk, as they dissolved rice husk equally well.
Autohydrolysis pretreatment of mixed hardwoods to extract value prior to combustion
Authors: Pu Yan , Treasure Trevor , Gonzalez Ronalds , Venditti Richard , Jameel Hasan
Published: June 2023

Biomass pretreatment by autohydrolysis uses hot-water to extract soluble components from wood prior to converting the woody residuals into paper, wood products, or fuel, etc. Mixed hardwood chips were autohydrolyzed in hot-water at 150, 160, 170, and 180 ºC, for 1 and 2 h. The tradeoff between fermentable sugar yield and caloric value of the residual solids was studied for a process that will be referred to as “value prior to combustion”. The extracted liquid was treated with dilute sulfuric acid to break down sugar oligomers into fermentable monomers. Material balances were performed around autohydrolysis to evaluate the role of temperature and residence time on sugar production and residual solid heating value. The composition (sugars and byproducts) of the extracted liquid was determined. As the autohydrolysis temperature increased, the material balance became less precise, presumably due to more volatile byproducts being formed that were not quantified. More hemicelluloses were extracted from the wood by the hot water extraction process under higher temperature and longer residence time, but a greater degree of sugar degradation was also observed. After hot-water extraction the heating value of the solid residues was higher than the original wood. The total energy content of the residual solid after extraction ranged from 74 to 95% of the original energy content of the feed.
Effect of production parameters on the physical and mechanical properties of particleboards made from peanut (Arachis hypogaea L.) hull
Authors: Güler Cengiz , Büyüksarı Ümit
Published: June 2023

In this study, effects of panel density and adhesive ratio on some physical and mechanical properties of peanut (Arachis hypogaea L.) hull particleboards for general purposes were investigated. Panels were manufactured with various densities (0.5, 0.6, 0.7, and 0.8 g/cm3) and adhesive ratios (core layer 8-9% and face layer 10-11%) using urea-formaldehyde (UF) as an adhesive. All panels were tested for some mechanical (internal bond, modulus of elasticity, and modulus of rupture) and physical (water absorption and thickness swelling) properties. Results indicated that increase in the panel density and adhesive ratio, resulted in an improvement in mechanical and physical properties. Only the panels with 0.8g/cm3 density almost met the requirements for the TS-EN 312 Standard for general purposes. Also, the boards having the lower mechanical properties tested in this study can be used as insulating material in buildings because such materials would not be subjected to any mechanical stress.
Mean intrinsic tensile properties of stone groundwood fibers from softwood
Authors: López Joan Pere , Méndez José Alberto , El Mansouri Nour-Eddine , Mutjé Pere , Vilaseca Fabiola
Published: June 2023

Stone groundwood (SGW) is a fibrous matter commonly prepared in a high yield process, and mainly used for papermaking applications. In this work, the use of SGW fibers is explored as reinforcing element of polypropylene (PP) composites. Due to its chemical and superficial features, the use of coupling agents is needed for a good adhesion and stress transfer across the fiber-matrix interface. The intrinsic strength of the reinforcement is a key parameter to predict the mechanical properties of the composite and to perform an interface analysis. The main objective of the present work was the determination of the intrinsic tensile strength of stone groundwood fibers. Coupled and non-coupled PP composites from stone groundwood fibers were prepared. The influence of the surface morphology and the quality at interface on the final properties of the composite was analyzed and compared to that of fiberglass PP composites. The intrinsic tensile properties of stone groundwood fibers, as well as the fiber orientation factor and the interfacial shear strength of the current composites were determined.
Optimized conditions for graft polymerization of poly(acrylamide) onto rubberwood fibre
Authors: Mahdavi Mahnaz , Ahmad Mansor B. , Haron Md. Jelas , Rahman Mohamad Zaki Ab. , Fatehi Asma
Published: June 2023

Graft copolymerization of acrylamide (Am) onto rubberwood fibre (RWF) was carried out by free radical initiation. Ceric ammonium nitrate was used as an initiator system. The effects of temperature, dose of initiator, ratio of monomer to fibre, and nitric acid concentration, on the grafting percentage were investigated. The optimum reaction temperature was found to be about 50°C for 4h and with an appropriate ratio of monomer to fibre of 3:1 wt/wt. The optimum concentration of initiator and nitric acid were 0.007 M and 0.2 M, respectively. The polyacrylamide (PAm) homopolymer was removed from the graft copolymer by Soxhlet extraction using distilled water. The pre-treatment RWF before the grafting procedure showed that grafting of acid-treated had a higher efficiency than alkali- treated and untreated RWF. Fourier transform infrared spectroscopy was used to confirm and characterize the PAm-graft-RWF.
Formation and evaluation of kraft fibre-reinforced unsaturated polyester (UPE) composites
Authors: Gao Zhenhua , Ma Dieying , Lv Xinying , Wang Qingwen
Published: June 2023

The effects of moulding pressure and initiator content on the performances of kraft fibre-reinforced UPE composites were investigated by means of tensile evaluation, DMA analysis, SEM analysis, and short-term creep tests. The results indicated that the prepared composites had much higher tensile strength and modulus and better creep resistance than traditional thermoplastic wood plastic composites (WPCs). These improved properties resulted from the incorporation of the strong kraft fibres as reinforcement. The combination of the fibers with the thermosetting UPE matrix produced enhanced kraft-UPE interfacial adhesion. Changes in moulding pressure and initiator level produced various effects in the properties of composites. As the moulding pressure increased from 6 MPa to 25 MPa, the mechanical properties and creep resistances increased gradually until a moulding pressure of 20 MPa was reached; after this point, the values decreased. With an increase in the initiator content from 0.3 PHR (parts per hundred parts of resin) to 1.0 PHR, the tensile strength and interface adhesion first increased, then decreased, while the instantaneous strain and maximum strain values (measured in the creep tests) decreased gradually.

Paper is a kind of historical sociology of religions for philosophical understanding of Al- Muhyiddin Arabi's research as a lasting paradigm in dialogue of religions. Mediterranean is place where greatest number of God's prophets were sent, and voice of prophecy of many prophets from Adam to Khatam can still be heard in that space. AL-Muhyiddin Arabi (1240), who started classical studies of religions, originated from Western Mediterranean and presented his works in eastern Mediterranean. His research has come as a paradigm that governs understanding of religions in their common subject, nature of prophets. Discussion of religions dialogue, in modern era, it is basically a question of oriental studies. Which Orientalism put it in two paradigms of Crusades and global unity of religions? Hypothesis of research is that dialogue between religions is an anthropological debate and is close to natural requirements of man. And good orientalist views are close to it. Discussion in paradigm of religions has a pattern of combination of philosophy and sociology, its origin is beyond science of religions. Dialogue of religions has a philosophical ontology in field of human existence and is a logical paradigm. There is a linear and circle approach to human history and in every attitude to history, religious dialogue, has a physical existence. Field of this philosophical opinion is anthropological process in history of sociology. In process of anthropology, there are at beginning of creation homogeneous group of people, without grounds of separation, and societies were homogeneous, and uniformity was their only characteristic, but societies also have secondary characteristics, which is essential necessity of change. And prophets who organize changes. Therefore, dialogue between religions has an existential place in societies, like reason for their existence, and it is a part of anthropology, and it has been investigated in combined science of philosophy and sociology in this research, and it shows that constant existence of dialogue between religions always has its own suitable contexts and has its own suitable contexts and discussion of religious dialogue in context of political issues is belonging complications of opposites orientalism circles, and in positive orientalism, attention is paid to ontological aspect of relationship between religions, and discussion of religions in this orientalism is closer to principle of ontology of religions, because religions are naturally for order. And the multiplicity of societies have arisen and their existence is rooted in people whose existential roots are of a uniform nature, and multitude of societies goes back to unity between people that existed in beginning because unit of society is Human(Nas). But according to historical Arrangement, in any way there are many societies.

Quantum effects in pycnonuclear reactions in compact stars at zero temperatures are studied with high precision. The reaction 16O + 16O was analyzed using the method of multiple internal reflections. The study of such reactions requires full consideration of quantum fluxes in the internal nuclear region. This reduces the rate and number of pycnonuclear reactions up to 1.8 times. This leads to the appearance of new states (which we call quasibound states) where the compound nuclear system is formed with maximal probability. As shown, the minimal energy of such a state is slightly higher than the energy of zero-mode oscillations in the lattice nodes in the pycnonuclear reaction, however, the probability of the formation of a compound system in a quasibound state is significantly greater than the corresponding probability in a state of zero-mode oscillations. It is reasonable to say that the frequency of reactions in quasi-bound states is more likely than in states of zero-mode oscillations. This can lead to significant changes in estimates of reaction rates in stars.

The article presents the results of the numerical simulation of the signal formation process of the background wires of self-powered neutron detectors (SPND) under the action of gamma radiation in the VVER-1000 core using MCNP code. The validation of the MCNP model was carried out on the results of experimental determination of the current of the background wires of the SPND, obtained at three different power units with VVER-1000 during the fuel campaign. The article also proposes a new gamma-ray method for determining the thermal power of the VVER-1000 reactor (TPR) based on the signals from the background wires of the SPND. TPR is an important safety parameter of VVER-1000, therefore, increasing the accuracy of determining TPR with the introduction of an additional gamma method for its determination is an urgent task, given the plans to increase the TPR of VVER-1000. The results of the experimental determination of the VVER-1000 TPR by the traditional neutron method based on the SPND signals are presented, and problematic issues regarding the error in determining the TPR by the neutron method are pointed out. The article presents the results of modeling to study the influence of the main factors affecting the change in the proportionality coefficient Kgm between the actual TPR and the TPR determined by the gamma method. To improve the accuracy of determining the TPR by the gamma method, a correction model for Kgm is proposed, which takes into account the effect of nuclear fuel burnup on the change in the signal of the background wires of the SPND. Taking into account that the signal of the background wires of the SPND is inertialess with respect to the change in the neutron power of the reactor, the introduction of the method for determining the TPR by the gamma method is promising for the implementation of an additional alternative channel for generating an emergency protection signal in terms of both power and the period of the reactor.

Theoretical concepts of the positron annihilation process in structural materials of nuclear reactors, taking into account the peculiarities of their electronic structure, have been developed. The Tao - Eldrup model, which allows to analytically calculate the lifetime of a positron in a spherically symmetric potential well, has been modified for the case of a potential well of finite height, in order to expand the limits of the model's application. The dependence of the positron lifetime on the height and width of the potential well, which occurs at the point defects, was determined. The results obtained within the framework of the modified model provide important information for the analysis of positron lifetime spectra in irradiated materials and data for the verification of quantitative calculations by the method of density functional theory.

Hafnium is used for the production of control rods and protective screens in nuclear reactors after its hot plastic deformation and final thermochemical treatment. This research presents the experimental results of the influence of the surface layer state on the oxygen diffusion saturation of hafnium during thermochemical treatment in an oxygen-containing gas medium. Two cases of the surface layer state were considered: in the initial (delivery) state and after grinding, where 50 μm of the surface layer was removed. Differences between the hardness distributions in the near-surface layer of HFE-1 hafnium after thermochemical treatment in an oxygen-containing gas medium were shown. It was found that thermochemical treatment of hafnium with a surface layer in its initial state leads to an increase of hardness in the near-surface layer compared to the surface: i.e., the near-surface layer hardness increases to a depth of 5 - 7 μm, and then gradually decreases to the matrix (core) hardness. It was determined that the fatigue life of hafnium after thermochemical treatment depends on the surface layer state. A 6.5 times higher fatigue life after thermochemical treatment of hafnium samples was fixed with a grinded surface compared to hafnium samples without grinding.

The results of the analysis of the radiation state of environmental objects in the sanitary protection zone (SPZ) and surveillance zone (SZ) of the research nuclear reactor (RNR) WWR-M of the Institute for Nuclear Research of the National Academy of Sciences of Ukraine (INR) for 2021 are analyzed and compared with the data for previous years (from 2016 to 2020). The levels of total beta activity of sedimentary dust and atmospheric precipitation and wastewater from the main reservoirs of INR, the concentration of beta-active aerosols in the surface layer of atmospheric air, as well as the content of 137Cs radionuclide in soil and vegetation samples, were studied. The research was conducted in the laboratory of the Center for Ecological Problems of Atomic Energy of INR. The obtained results show that in 2021 there was no excess of the values of controlled parameters compared to previous years. There was also no significant difference in the specific activity of the radionuclide 137Cs in soil and vegetation samples from SPZ and ZS. Studies conducted in the period from 2016 to 2021, allowed to accumulate significant factual material on the radiation situation in the sanitary protection zone and surveillance zone and to substantiate the conclusion about the absence of man-made radioactive contamination of the environment due to the operation of RNR WWR-M of INR of NAS of Ukraine.
