Paleogenomics and Archaeology: recent debates about the spread of steppe ancestry in Westernmost Europe
Authors: Vicent-García Juan M. , Martínez-Navarrete María Isabel
Published: April 2022

The recent development of paleogenetics has had a large impact on much of archaeology. Particularly surprising has been the discovery of a connection between the Iberian Peninsula and the Eurasian steppes, an unexpected link between the first stages of metallurgy at opposite ends of Europe. Recent studies of human remains from Copper and Bronze Age Spain and Portugal have shown a significant presence of genomes of types geneticists attribute to the Yamnaya culture and historical community. Geneticists had already identified this genome in central European archaeological contexts. Interpretation of these results has led to controversy concerning their historical significance and their importance for explaining important cultural changes, such as the origin of the Bronze Age in Iberia. As a result, many Spanish and Portuguese prehistorians have “discovered” the cultures of the steppes. Their inclusion has broadened and enriched debates concerning Iberian prehistory. This article reviews recent literature so as to assess the state of play on the contribution of paleogenetics to Iberian prehistory and to reflect on the impact of the Yamnaya culture’s unexpected burst onto its scene.

Published: April 2022

Авторами анализируются результаты раскопок поселений финальной бронзы ивановской (хвалынской) и бондарихинской культур в Среднем Подонье. В Побитюжье раскопаны два поселения бондарихинской культуры, выявлены закрытые комплексы, позволяющие детально охарактеризовать керамическую и орудийную специфику культуры. На юге Среднего Дона изучено поселение Журавка 1, где прослежены комплексы ивановской (хвалынской) культуры. В среднем течении р. Битюг (левый приток р. Дон) раскопаны поселения Бобров 2 и 3. Получены новые материалы финала эпохи бронзы. Сделаны выводы о связи донских материалов с сопредельными регионами. Результаты исследований поселений Журавка 1 и двух поселений у г. Бобров позволяют расширить представления о культурных процессах, проходивших в восточноевропейской лесостепи в конце II тыс. до н.э.

Published: April 2022

В статье представлены результаты палинологических исследований, полученных при изучении насыпи вала Маклашеевского II городища. Согласно этим исследованиям догородищенское поселение ананьинской культурно-исторической области, возникшее во второй половине VII – первой половине VI вв. до н.э., окружали березовые леса, перемежаемые открытыми пространствами с разнотравьем и злаками. Такая ситуация сохранялась и к началу строительства оборонительных сооружений в VI–V вв. до н.э. В V в. до н.э., когда вал был достроен, в окрестностях городища произрастали хвойно-широколиственные леса, в составе которых присутствовала сосна, липа, береза. Большие пространства оставались свободными от леса. Растительное окружение Маклашеевского II городища в раннем средневековье, когда на городище поселились носители именьковской культуры, не удалось определить, так как строительство (последняя четверть IV – первая четверть V в. н.э.) и достройка (VI–VII вв. н.э.) насыпи вала осуществлялась из грунта нижних почвенных горизонтов. В постименьковское время городище было заброшено, а в его окрестностях распространились полуоткрытые пространства с преобладанием разнотравно-злаковых сообществ. Леса были небольшими и состояли из сосны и березовых перелесков.

Авторам данной статьи посчастливилось, начиная с 1993 г., принимать участие в исследованиях на горно-металлургическом комплексе бронзового века в Каргалах, что стало возможным благодаря любезному приглашению со стороны его руководителя Е.Н. Черных. Этот опыт чрезвычайно обогатил авторов как ученых, предоставив возможность напрямую изучить конкретные проблемы, традиции и практику российской археологии в контексте такого важного проекта. Более того, участие в работе группы Каргалы оказалось очень ценным в смысле чисто человеческом и личностном, поскольку свело авторов с группой коллег, с которыми, и по сей день, авторы поддерживают отношения дружбы и товарищества, а также интенсивный и плодотворный обмен научной информацией. Убедительным подтверждением тому служит пример С.В. Кузьминых, от которого авторы статьи научились многому как из области научной, так и жизненного опыта, благодаря редкой возможности совместно проводить полевые изыскания в степи, участвовать в рабочих совещаниях в Москве и других встречах. Настоящая статья ставит перед собой задачу поделиться приобретенным опытом и выразить глубокое уважение к личности С.В. Кузьминых – ученого и человека.

Assessment of urban air pollution in the Leninsky district of Vladivostok
Authors: Makarova Vera , Pchelkin Alexander , Isaeva Irina
Published: April 2022

В статье проведена оценка состояния окружающей среды города с помощью биоиндикации. Цель работы – определение уровня загрязнения атмосферного воздуха на территории Ленинского района города Владивостока. По мере развития промышленности, энергетики и средств транспорта антропогенное загрязнение биосферы, обусловленное жизнедеятельностью человека, непрерывно растет. Выбросы промышленных предприятий, энергетических систем, автотранспорта в атмосферу оказывают прямое воздействие на все живое. Изучение последствий антропогенного воздействия на окружающую среду проводилось с применением методов биологической индикации. Для этого использовались живые организмы в качестве биоиндикаторов, отражающие состояние окружающей среды. Оптимальными биоиндикаторами в городе являются листья березы, поскольку это деревья с высокими поглотительными способностями. При формировании листовой пластины по мере накопления токсичных веществ происходит торможение ростовых процессов и деформация листа. Наиболее доступная и широко применяемая морфогенетическая мера нарушения стабильности развития – флуктуирующая асимметрия. Оценка качества атмосферного воздуха Ленинского района города Владивостока по флуктуирующей асимметрии листьев березы пушистой (Вetula pubescens Ehrn.) позволила определить качество среды путем изучения асимметрии листьев березы. Научная новизна работы состоит в оценке пригодности использования методики биологической индикации в районах со специфическими природно-климатическими характеристиками, которые будут влиять на аэрационный режим территории. Практическая значимость работы заключается в том, что в результате исследования берез вблизи автомобильных дорог получены данные, которые свидетельствуют о том, что на территории Ленинского района качество среды оценено как крайне неблагоприятное, что является результатом отрицательного антропогенного воздействия на окружающую среду.
State-Based Policy Supports for Refugee, Asylee, and TPS-Background Students in US Higher Education
Authors: Unangst Lisa , Casellas Connors Ishara , Barone Nicole
Published: April 2022

Higher education for displaced students is rarely the focus of academic literature in the context of the United States, despite 79.5 million people displaced worldwide as of December 2019 and 3 million refugees resettled in the United States since the 1970s (UNHCR, 2020). An estimated 95,000 Afghans will be resettled in the US by September 2022, and the executive branch has requested $6.4 billion in funds from Congress to support this resettlement process (Young, 2021). This represents the most concentrated resettlement in the US since the end of the Vietnam War. It is therefore clear that policy supports for displaced students represent a pressing educational equity issue. This paper applies critical policy analysis to state-level policies supporting displaced students and argues that both data gaps and policy silence characterize the current state of play.

Estudio de propiedades mecánicas de un material compuesto de matriz de polipropileno con fibra de guadua y polvo de cerámica
Authors: Salamanca-Cárdenas Jefferson David , Pineda-Daza Yeisy L
Published: April 2022

El uso de fibras de origen natural como refuerzo en Materiales Compuestos (MC), ha venido tomando fuerza en los últimos años. En este caso se tiene un MC con matriz de polipropileno (PP) reciclado, proveniente de tapas de diferentes envases de productos de consumo diario. Para el refuerzo se eligió usar fibra natural de Guadua angustifolia y polvo de cerámica tenaz. La fibra de Guadua se obtuvo en condiciones de secado e inmunizado con el fin de reducir su humedad y evitar la aparición de hongos y líquenes. El polvo de cerámica tenaz también es un material reciclado, obtenido de pisos de cerámica que se trituraron y pulverizaron previo a la inserción al MC. Las proporciones usadas para fabricar las probetas del MC fueron: una con 100% de PP y otras con diferente composición del MC, donde la matriz de PP se mantuvo con el 60%, y se combinaron los materiales de refuerzo, para obtener los siguientes grupos de especímenes, uno con 30% fibra y 10% cerámica, otro con 33% fibra y 7% cerámica y un último con 35% fibra y 5% cerámica. Una vez obtenidas las probetas del MC, se realizaron los ensayos mecánicos, de tensión según la norma ASTM 638D para polímeros, y de flexión con la norma ASTM 970D para plásticos reforzados. Se analizaron los resultados obtenidos, mediante análisis de varianza (ANOVA), usando un nivel de significancia de α = 0.05 y un enfoque de valor P para la verificación de la hipótesis nula. El análisis estadístico se realizó mediante el software Minitab 18, encontrando como resultado más importante, que el módulo de elasticidad a tensión del PP aumentó en un 53,49%, al adicionarle Guadua en un 35% y cerámica en un 5%.
Caracterización de la resistencia a la compresión en rocas mediante clasificación granulométrica: un ensayo de campo
Authors: Feijoo Calle Ernesto Patricio , Ureña Carlos A.
Published: April 2022

El objetivo de este trabajo es establecer una relación entre el tamaño, luego del proceso de fragmentación de los materiales, mediante la determinación del D80 y el índice de carga puntual Is (50), para de esta forma caracterizar la roca en términos de resistencia y evitar el envío de muestras permanentemente a laboratorios. Se inició la propuesta con la toma de muestras de roca de un sector específico denominado Cojitambo, en la provincia de Cañar (Ecuador), en el que aflora una andesita de grano fino. Estas muestras fueron tomadas evitando que sean meteorizadas, para que sean lo más frescas posible. En una segunda etapa se elaboraron probetas con las muestras, 60 en total, 30 con dimensiones aproximadas de 5 cm x 5 cm x 5 cm., las cuales fueron al proceso de ruptura, es decir para la determinación del Is (50), y 30 probetas de aproximadamente 5 cm x 5 cm x 10 cm., las cuales se sometieron al proceso de trituración y clasificación. En una etapa final se ha determinado una relación existente entre el D80 y el Is (50), la cual permite establecer que, si las rocas o muestras tomadas en el campo están dentro de esta relación, se determine su resistencia, o caso contrario sean enviadas las mismas al laboratorio para su valoración. La propuesta presenta una ecuación para la determinación de la resistencia a la compresión simple de la roca de una manera aproximada y de fácil interpretación, logrando que en un proyecto minero exista un ahorro significativo en términos económicos y de tiempo.
Mechanical, physical and thermoacoustic properties of lightweight composite geopolymers
Authors: Villaquirán-Caicedo Mónica A. , Perea Vilmary N. , Ruiz Jhon E. , de Gutiérrez Ruby Mejía
Published: April 2022

This research evaluates the physical and mechanical properties of particulate composites, produced from geopolymer paste with the incorporation of different organic type wastes as expanded polystyrene (EP), corkwood (CK), tire rubber (RB); in percentages by volume of 2, 4, and 6%. Metakaolin was used as a precursor of the geopolymer produced by alkali activation from NaOH and sodium silicate. The geopolymer composites were cured at room temperature. Properties as density, porosity, absorption, compressive strength, thermal conductivity, and acoustic behavior were evaluated. As complementary techniques, light and scanning electron microscopy were used. It was observed that the high alkalinity of the geopolymer mixture causes deterioration of the CK particles. Composites with the incorporation of 4% of the EP and RB particles reported compressive strength of 32 and 45 MPa at 28 days, and apparent density of 1853 and 1922 kg/m3, respectively, which represents a reduction of 6.08% and 2.58% in comparison to the GP reference. The thermal conductivity for composites with 4% of EP and RB was 0.316 and 0.344 W/m.K and the sound absorption coefficient was evaluated at frequencies of 500 Hz, 0.70, and 0.50 respectively. The evaluated performance properties show the feasibility of using 4% of EP and RB for the manufacture of geopolymer composites for applications in thermal and sound insulating panels.

El “Diario palestino” (1988) de Juan Goytisolo: un reportaje en primera persona sobre la Intifada palestina y la ocupación israelí
Authors: Del Campo Cortés Eduardo
Published: April 2022

El escritor español Juan Goytisolo (1931-2017) recurrió al reportaje ensayístico en primera persona para la escritura de los textos testimoniales que elaboró sobre diversos conflictos armados, entre ellos, el del pueblo palestino bajo la ocupación israelí de Gaza y Cisjordania, uno de los temas principales en su literatura periodística. Es el caso de “Diario palestino”, relato del primero de sus cuatro viajes a Palestina e Israel, cuando en 1988 recorrió la zona en plena Intifada o revuelta palestina para rodar un episodio de la serie de televisión Alquibla, una historia que publicó ese año en la revista El País Semanal y que incluyó en su libro, de 1997, De la Ceca a La Meca. El presente ensayo describe y analiza la crónica del autor, que usa el “yo” como fuente de autoridad informativa para reforzar el valor documental de sus descripciones y entrevistas.
Perspectives for a community-driven tourism in Cape Verde
Authors:   Università di Roma ", Bozzato Simone ,   Tor Vergata",   (Italia), Pollice Fabio ,   University of Salento (Italia)
Published: April 2022

In developing countries, most of the time, tourism is characterised by an exogenous variable. Instead of reducing social issues, not only does this characteristic feature increase them but it also has negative repercussions on a cultural level and on the environment, with complete disregard for the key principles of sustainable development. Local communities are not usually able to interpret the potential for tourism development since they do not share common core needs with it. Consequently, the underlying needs of international tourism flows are neither interpreted nor understood. In this paper, the proposed strategy is community‑based tourism. Its core can be found in the integral mapping and management of every single component of Cape Verdean tourism that is given in the most interesting areas in terms of environment, landscape, and culture on the island. The development of identifying social and cultural traits plays a fundamental role when considering the balance between the tourist’s needs and expectations, and the needs of the host population.
Cientificidade nos estudos do turismo. Teorias, dicotomias e o desafio da consolidação epistemológica
Authors:   Universidade Federal de Sergipe (Brasil), Sampaio Eliane Avelina de Azevedo
Published: April 2022

Tourism as a field of disciplinary study has theoretical propositions and epistemological knowl‑ edge capable of elevating it to the status of a science. Various researchers have carried out analyses that show the fragility of tourism as a possible science, and postulate theories that contribute to the advance‑ ment of studies in the area. Thus, this article is aimed at building a line of analysis, focusing on the empiri‑ cal repetition of theories and concepts that portray tourism as a multidisciplinary, interdisciplinary and transdisciplinary area of study. In addition to the importance of overcoming paradigmatic issues towards an epistemological consolidation. Methodologically, it his theoretical and exploratory, using bibliographic and electronic research to chart the maturing of tourism studies and to reflect the intrinsic complexity of the area. In the end, it appears that different fields of knowledge may interact at different levels of complexity under a multi‑inter‑trans disciplinary perspective in tourism. However, there is a need for an overall philosophy in order to produce cohesion toward forming an independent science.

The implementation of the Pueblos Magicos Programme (PPM) in Mexico is producing profound transformations in tourist destinations and in the lifestyles of intervening social agents. The objective of the research was to analyse various theoretical and methodological contributions of the stakeholder‑ ‑centred approach, to design an analysis framework that would allow understanding of the PPM as a planned intervention, and its impact on the social interface, lifestyles and participation of the stakehold‑ ers. Methodologically, a review of the specialised literature and the analysis‑synthesis method were used to specify the categories of analysis. As a result, an analysis framework is presented, which allows for the perspective of the stakeholders involved to be reflected and their response in general to the programme. It is concluded that this framework is valid toward understanding the PPM as a planned intervention, the transformation processes that it generates and the strategies that the stakeholders develop to face the challenges that tourism entails.
Activación de patrimonios comunitarios y turismo sustentable: el caso de Etzatlán, Jalisco
Authors: Concepción Sánchez María de la
Published: April 2022

Tourism has become a possibility for many small Mexican municipalities to keep their communi‑ ties alive and offer new job opportunities to their population, in the face of changing productive systems and lifestyles. In the case of Etzatlán, Jalisco, this possibility has been explored by different administrations, without success so far. In 2019, a participatory project was proposed to the local authorities to generate a model of sustainable and supportive tourism. This model was to meet two criteria: the role of the tourist in the decision‑making process and the mechanisms to redistribute the possible earnings generated by their arrival. From an ethnographic map of potential biocultural heritages, proposals were forwarded to the local community for them to consider. In this paper we present the methodology and the main results of these strategics in local government and planning, as well as the restrictions. The article finishes with a reflection on the possibilities of replicating this methodology in other communities and the role that horizontal meth‑ odologies could play to greater success with the objectives set by the populations themselves.

Knowledge Management (KM) is seen as a strategy to create competitive advantage. Therefore, the objective of this research is to understand the application of KM in tourism. The guidelines of the PRIS‑ MA recommendation (Preferred Reporting Items for Systematic Reviews and Meta‑Analyses) were followed for the development of an integrative literature review, using the Scopus and Web of Science databases thus allowing for the review to be transparent and possible to be reproduced. Briefly, the checklist items and a flowchart for selecting articles, both from PRISMA, substantiated the form and content of the review, the process of selecting the articles, and the central design for the information extracted and enabling the data analysis. A sample of 376 articles was obtained, of which 107 met the seven eligibility criteria. In this process of systematic search and sorting of articles, the bibliographic manager EndNote was used, and for each article there was analysis by at least two researchers. The highlighted results were: (1) tourism lags behind other economic sectors in its use of KM; (2) the majority of researchers are located in Europe; (3) the most popular magazines for publication are from the tourism area itself; (4) most research used empirical methods, with a tendency towards the quantitative approach; (5) the emphasis is on knowledge sharing and transfer processes; (6) emphasis on tacit knowledge, given the complexity of its management.
ZAŠTITA TRADICIJSKIH PROIZVODA PRIMJENOM ZEMLJOPISNIH OZNAKA U EUROPSKOJ UNIJI NAKON STUPANJA NA SNAGU ŽENEVSKOG AKTA NA LISABONSKI SPORAZUM

The aim of this paper is to explore the possibilities of protection of geographical indications marking traditional products in the European Union, especially after the entry into force of the Geneva Act of the Lisbon Agreement on Appellations of Origin and Geographical Indications. The current possibilities of protection at the international level serve as a starting point. The most significant changes brought about by the Geneva Act have been indicated in the paper and the consequences of the European Union accession to this international agreement have been analysed in detail. The research shows the advantages in terms of protection of geographical indications after the accession of the European Union to the Geneva Act only related to traditional agricultural and food products, whereas, for example, traditional handicrafts, souvenirs and other non-agricultural products do not benefit therefrom. Moreover, the results of the research show that while the European Union has managed to expand the policy of protection of geographical indications at a global level through the adoption of the Geneva Act, its position has been weakened by the fact that there is no sui generis system of protection of designations of origin and geographical indications for non-agricultural products in the European Union. The paper also analyses the advantages, disadvantages and limitations of the traditional products protection through the geographical indications protection marking them, and it emphasizes the importance of geographical indications protection for indigenous non-agricultural products (souvenirs) for tourist destinations such as the Republic of Croatia. The conclusion of the research supports the need for establishing a system of geographical indications protection for non-agricultural products at the European Union level in order to enable the protection of geographical indications for all traditional products in the European Union through the established system of international registration.

Authors: Kasap Jelena
Published: April 2022

Drawing up marriage contracts in order to achieve the autonomy of the parties with regard to property relations in marriage in the period after the entry into force of the Austrian General Civil Code has become a common practice. A very detailed normative framework for the regulation of individual institutes of marital law left enough space to regulate property relations between spouses in accordance with their requirements and with the purpose of preserving the economic interests of the family and each partner. In the period in which a man took over the function of managing marital property, and the position of a married woman was marked by patterns of desirable behaviour, a number of property dispositions were recorded with the purpose of strengthening a woman's position in society during marriage, but also securing her status in the case of termination of marriage. Guided by the idea of modernizing the social position of women in the period after the entry into force of the Austrian Civil Code, the basic purpose of this research is to determine the position of women in terms of property rights acquired on the basis of private legal documents. This refers to the institutes included in the content of marriage contracts preserved in the State Archives in Osijek and the effects of wills, which often contained marriage provisions, but also those wills whose creators often sought to provide property protection for poor women by establishing foundations. Available documents come from different legal areas of urban (Osijek) and rural (Baranja) areas, which makes them a valuable material for a comparative analysis of various issues, from applicable law to the effects of its application. Therefore, this research uses a legal-historical method and a comparison of the obtained results to try to determine the effects of marriage law and the impact of contractual dispositions on the economic and legal strengthening of the position of women in the society in the second half of the 19th century.

Published: April 2022

Objective:

The objective of the study was to assess the practices of caregivers of under-5 children in the study area, regarding the use of antibiotics.

Material and Methods:

A descriptive, cross-sectional study was conducted among 270 respondents selected by multistage sampling technique. Data were collected using interviewer-administered questionnaires and analyzed with Statistical Package for the Social Sciences software (version 25.0).

Results:

Majority (81.8%) of the caregivers were within the ages of 20–39 years. Most (78.1%) were female and 82.2% were married. Most (88.9%) of the caregivers were the biological parents of the children. About 97% of them were assessed to have good antibiotic use practices; although a few poor practices were also reported. These include home use of antibiotics without prescription, prematurely discontinuing courses of antibiotics and directly requesting for antibiotics from physicians.

Conclusion:

Public health education and enlightenment regarding the demerits of poor stewardship of antibiotic use coupled with strict regulatory control measures in the dispensing and sale of antibiotics as over-the-counter medications are recommended to improve antibiotic use practices among caregivers of young children.
Carotid artery dissection due to elongated styloid process treated by acute phase carotid artery stenting: A case report
Authors: Okada Yasuaki , Mitsui Nobuyuki , Ozaki Hirokazu , Sanada Takahiro , Yamamoto Shota , Saito Masato , Kinoshita Manabu
Published: April 2022

Background:

Eagle’s syndrome is famous for one of the causes of internal carotid artery dissection. The treatment strategy for the illness, however, is not well established. Here, we report a case of internal carotid dissection due to an elongated styloid process successfully treated by carotid artery stenting (CAS).

Case Description:

A 72-year-old male with temporary dysarthria and consciousness disorder was diagnosed to suffer from multiple cerebral infarctions due to Eagle’s syndrome. A cerebral blood flow (CBF) study revealed decreased blood flow and a CAS was performed 15 days after admission to preserve antegrade blood flow, resulting in full recovery of the affected CBF.

Conclusion:

We reported a case of vascular Eagle’s syndrome in which the patient showed fluctuated neurological deficits successfully treated by CAS. Our experience suggests that cases of vascular Eagle’s syndrome due to hemodynamic stress can be treated by CAS.
Adding Numbers to the SHIQ Description Logic - First Results
Authors:   RWTH Aachen, LuFG Theoretical Computer Science, Lutz Carsten
Published: April 2022

Recently, the Description Logic (DL) SHIQ has found a large number of applications. This success is due to the fact that SHIQ combines a rich expressivity with efficient reasoning, as is demonstrated by its implementation in DL systems such as FaCT and RACER. One weakness of SHIQ, however, limits its usability in several application areas: numerical knowledge such as knowledge about the age, weight, or temperature of real-world entities cannot be adequately represented. In this paper, we propose an extension of SHIQ that aims at closing this gap. The new Description Logic Q-SHIQ, which augments SHIQ by additional, 'concrete domain' style concept constructors, allows to refer to rational numbers in concept descriptions, and also to define concepts based on the comparison of numbers via predicates such as < or =. We argue that this kind of expressivity is needed in many application areas such as reasoning about the semantic web. We prove reasoning with Q-SHIQ to be EXPTIME-complete (thus not harder than reasoning with SHIQ) by devising an automata-based decision procedure.
Free Metallophosphines: Extremely Electron-Rich Phosphorus Superbases that are Electronically and Sterically Tunable
Authors: Wei Rui , Ju Shaoying , Liu Liu Leo
Published: April 2022

A variety of research fields ranging from catalysis to materials science benefit from readily accessible electron-rich ancillary ligands such as phosphines with diverse stereoelectronic properties. We report herein a facile and highly modular access to an intriguing class of free Au-substituted phosphines (AuPhos), namely (LAu)nPR3-n (L = singlet carbene ligand; R = H, aryl, alkyl, silyl) (n = 1-3). The Tolman electronic parameter (TEP) values coupled with theoretical investigations showcase that Au-substitution can boost the electron-releasing ability of AuPhos, thus leading to an electronically and sterically tunable, extremely electron-rich phosphorus center. The high basicity of AuPhos is attributed to the d-p lone pair π-repulsion arising from interaction between electron-rich d10 Au substituents and the lone pair at P. A series of multi-nuclear transition metal complexes (i.e. Rh, Ir, Pd, Au, W, Mn) ligated by AuPhos are readily prepared via a straightforward process.

Engineering the local dynamic environment is currently the major approach for preventing fast magnetization loss for single-molecule magnets (SMMs). It is hypothesized that the presence of fewer −CH3 which results in fewer C−H bonds, would reduce excitation energy loss via vibrations, but thus far, no experimental evidence clearly elaborates this effect. Moreover, although Gu and Wu proposed a vibronic barrier model to interpret the Raman process, the relationship between the barriers (\hbar\omega) and the molecular structure has not been explicitly correlated. Here, we use the trifluoromethyl group to systematically substitute the methyl groups in the axial position of the parental bis-butoxide pentagonal-bipyramidal dysprosium(III) SMM - [Dy(OtBu)2(py)5][BPh4]. The resulting complexes - [Dy(OLA)2py5][BPh4] (LA = CH(CF3)2− 1, CH2CF3− 2, CMe2CF3− 3)- show progressively enhanced TBhys (@100 Oe/s) from 17 K (for 3), 20 K (for 2) to 23 K (for 1). As the gradually enhanced averaged vibration energy generated by different axial ligands from 230 cm−1 (for 3), 257 cm−1 (for 2) to 321 cm−1 (for 1) was identified experimentally and theoretically to be the only variant that leads to this improvement, this finding unambiguously reveals, for the first time, the correlation between structural change and the multi two-phonon (Raman) relaxation processes in lanthanide-based SMMs and highlights the importance of controlling the relevant vibrations in building SMMs with higher blocking temperatures.

Published: April 2022

Rotating ring disk electrodes (RRDEs) are a powerful and versatile tool for mechanistically investigating electrochemical reactions at electrode surfaces, particularly in the area of electroanalysis and catalysis. Despite their importance only limited electrode materials (typically glassy carbon, platinum and gold) and combinations thereof are available commercially. In this work we present a method employing 3D printing in conjunction with machined brass components to produce housing which can accommodate any electrode material in e.g. pressed powdered pellet, wafer, rod, foil or vapor deposited onto a conductive substrate, form. In this way the range and usability of RRDEs is extended. This custom DIY approach to producing RRDEs, also enables RRDEs to be produced at a significant fraction of the cost of commercial RRDEs. To illustrate the versatility of our approach, co-planar boron doped diamond (BDD) RRDEs are fabricated for the first time, using the approach described. Experimental collection efficiencies for the redox couple FcTMA+/FcTMA2+ are found to be very close to those predicted theoretically. BDD electrodes serve as an ideal electrocatalyst support due to their low background currents, wide solvent window in aqueous solution and chemical and electrochemical stability in acid and alkali solutions. The BDD RRDE configuration is employed to investigate the importance of surface incorporated non-diamond carbon in BDD on hydrogen peroxide generation via the oxygen reduction reaction in acid solutions.

Published: April 2022

The library website is a task-oriented webpage(s) that requires regular evaluation. However, analyzing the content and aesthetic qualities of a library website is an essential ingredient for its usability testing. Hence, this study evaluated the content qualities and aesthetic features of university library websites in Southwest Nigeria. The study adopted a descriptive survey research design. The unit of analysis comprises undergraduate students from the six selected universities in southwest Nigeria, and their population stood at 99, 939. The study used a simple random sampling technique to select its samples and the sample size for the study is 398. A checklist and questionnaire were used as instruments for data collection. Collected data were analyzed using Statistical Package for Social Sciences (IBM-SPSS) version 21. The result of findings indicated that premium is placed more on aesthetic features than content quality and none of the understudy library websites has features for Frequently Asked Questions (FAQ), list of the new arrivals and space for advert placement. Based on the study analysis, the Kenneth Dike Library website of the University of Ibadan and Covenant University Resource Centre is better in terms of content quality than other university library websites in Southwest Nigeria. Library websites were found to be useful and yet not optimally utilized by the users due to the absence of some content and aesthetic features that tend to improve the usability of the library website. Consequently, the university library needs to prioritize its presence online and as well add features that will engage and elicit feedback from users. They also need to publicize among the users the use of library websites as veritable sources of scholarly information and communication.
