Toeplitz operators on non-reflexive Fock spaces
Authors: Fulsche Robert
Published: January 2024

We generalize several results on Toeplitz operators over reflexive, standard weighted Fock spaces

F_t^p

to the non-reflexive cases

p = 1, \infty

. Among these results are the characterization of compactness and the Fredholm property of such operators, a well-known representation of the Toeplitz algebra, and a characterization of the essential center of the Toeplitz algebra. Further, we improve several results related to correspondence theory, e.g., we improve previous results on the correspondence of algebras and we give a correspondence theoretic version of the well-known Berger–Coburn estimates.
Диффеоморфизмы Морса-Смейла с неблуждающими точками попарно различных индексов Морса на 3-многообразиях
Authors: Pochinka Olga Vital'evna , Talanova Elena Anatol'evna
Published: January 2024

В настоящей работе мы рассматриваем класс $G$ сохраняющих ориентацию диффеоморфизмов Морса-Смейла $f$, заданных на замкнутом 3-многообразии $M^3$, неблуждающее множество которых состоит из четырех неподвижных точек с попарно различными индексами Морса. Из результатов работ С. Смейла и К. Мейера следует, что все градиентно-подобные потоки с аналогичными свойствами имеют энергетическую функцию Морса с четырьмя критическими точками попарно различных индексов Морса. Это означает, что несущее многообразие $M^3$ для этих потоков допускает разложение Хегора рода 1, и, следовательно, оно гомеоморфно линзовому пространству $L_{p,q}$. Несмотря на простую структуру неблуждающего множества диффеоморфизмов в классе $G$, существуют диффеоморфизмы с дико вложенными сепаратрисами. Согласно результатам В. З. Гринеса, Ф. Лауденбаха, О. В. Починки такие диффеоморфизмы не обладают энергетической функцией, и вопрос о топологии их несущего многообразия остается открытым. Согласно результатам В. З. Гринеса, Е. В. Жужомы и В. С. Медведева $M^3$ гомеоморфно линзовому пространству $L_{p,q}$ в случае локально плоского вложения замыканий одномерных сепаратрис диффеоморфизма $f\in G$. Более того, блуждающее множество диффеоморфизма $f$ содержит по меньшей мере $p$ некомпактных гетероклинических кривых. В настоящей работе аналогичный результат получен для произвольных диффеоморфизмов класса $G$. На каждом линзовом пространстве $L_{p,q}$ построены диффеоморфизмы из класса $G$ с диким вложением одномерных сепаратрис. Такие примеры ранее были известны только на 3-сфере. Также установлено, что топологическая сопряженность диффеоморфизмов класса $G$ с единственной некомпактной гетероклинической кривой полностью определяется эквивалентностью узлов Хопфа, являющихся проекциями одномерных седловых сепаратрис в пространство орбит бассейна стока. Более того, любой узел Хопфа $L$ реализуется таким диффеоморфизмом. В этом смысле полученный результат подобен классификации диффеоморфизмов Д. Пикстона, полученной Х. Бонатти и В. З. Гринесом.

CUSTO DE CAPITAL ESTIMADO PELA ANEEL E SEGUNDO A TEORIA FINANCEIRA PARA O SETOR DE DISTRIBUIÇÃO DE ENERGIA ELÉTRICA: uma análise comparativa
Authors: Bueno Emilene Francisco , Albuquerque Andrei Aparecido de , Carvalho Flávio Leonel de
Published: January 2024

Este estudo teve como objetivo comparar o custo de capital obtido a partir da regulação da ANEEL, para aplicação nas revisões tarifárias do setor durante o triênio 2015-2017, com o custo de capital auferido pelas distribuidoras de energia elétrica, a partir de seis modelos alternativos de cálculo baseados na teoria financeira. Para isso, analisaram-se dados referentes a uma amostra 10 empresas de distribuição de energia elétrica de capital aberto que tiveram seus processos definitivos de revisão tarifária concluídos nesse triênio e, por meio do teste não paramétrico de Wilcoxon para amostra única, avaliou-se a hipótese de igualdade da mediana do custo do capital apurado conforme modelos indicados pela teoria financeira com o custo do capital determinado pela ANEEL. Como principal resultado, constatou-se que a remuneração determinada pela agência é, na maioria dos modelos analisados, superior ao custo do capital calculado. Desse modo, verifica-se que o custo de capital determinado pelo Estado está remunerando os investidores das concessionárias de distribuição de energia elétrica acima do custo de oportunidade do negócio calculado neste estudo, proporcionando uma maior atratividade para os investimentos, porém, onerando os consumidores.

Published: January 2024

As organizações têm manifestado preocupações crescentes sobre o Investimento Socialmente Responsável, uma vez que ele não considera apenas o retorno financeiro, mas pondera as práticas Environmental, Social, Governance (ESG) que são criadas para estabelecer dimensões adicionais do desempenho corporativo, as quais não se limitam a dados financeiros. Essas práticas sustentáveis proporcionam, às empresas, maior competitividade no mercado e maior reconhecimento pelos acionistas, tornando-as diretamente ligadas ao poder inovativo que as organizações possuem. Além disso, a forma pela qual a empresa cuida e gerencia o ambiente natural em que está inserida determina essas práticas ESG, as quais são consideradas como um diferencial no processo de alavancagem no mercado. Desta forma, o objetivo deste estudo é avaliar o efeito das práticas ESG na Inovação em um contexto de empresas brasileiras listadas na Brasil Bolsa Balcão (B3). Para tanto, realizou-se pesquisa descritiva, documental e com uma abordagem quantitativa, por meio da análise dos dados secundários extraídos da Refinitiv Eikon. A amostra da pesquisa correspondeu a 125 empresas listadas na B3 durante o período entre 2016 e 2020. Os resultados apontam uma relação significativa e positiva entre as variáveis ESG e a capacidade de inovação ambiental, como também uma relação positiva e significativa na probabilidade de as empresas apoiarem o Objetivo de Desenvolvimento Sustentável nº 9, Indústria, Infraestrutura e Inovação. Com isso foi possível identificar a necessidade de se propor políticas de apoio à adoção e incentivo das práticas ESG, para, assim, promover uma maior capacidade de inovação às empresas.

Os resultados apontaram que, na Fundação, a mudança institucional de regras e rotinas da contabilidade gerencial deu-se ao longo do seu período de atuação, suscitando em informações mais ágeis e seguras para a tomada de decisão. A mudança da contabilidade gerencial ocorreu sob a influência do isomorfismo coercitivo, mimético e normativo, e foi guiada por racionalidade e eficiência, para legitimação das ações, redução de incertezas e harmonia com as convenções aceitas. No intuito de alcançar legitimidade, as ações da contabilidade gerencial foram adequadas a um padrão de comportamento legal e socialmente aceito, e ao reconhecimento da Fundação como necessária à comunidade. O estudo amplia o entendimento da contabilidade gerencial para prover legitimidade às atividades da organização, no campo institucional do terceiro setor, área negligenciada na literatura contábil. A pesquisa contribui por apresentar evidências empíricas sobre mudanças na contabilidade gerencial ao longo do tempo, sob a influência das pressões isomórficas e das estruturas que lhe conferem legitimidade, no contexto do terceiro setor brasileiro, sugerindo novos estudos.
The role of layered double hydroxides shell in enhancing the adsorption capacity of NaY zeolite for toluene in wet conditions
Authors: Li Yanyao , Yin Tao , Xu Jiawen , Liu Naiwang , Shi Li , Meng Xuan
Published: January 2024

Surface modification of zeolite is known to enhance its adsorption capacity for volatile organic compounds (VOCs). In this study, a hydrophobic adsorbent, NaY@LDHs, with layered double hydroxides (LDHs) as the shell and NaY zeolite as the core, was successfully synthesized. It was found that treating LDHs with ethanol can result in a larger specific surface area and pore volume, enhancing the adsorption performance of toluene under wet conditions. SEM imaging reveals that the LDHs shell grows vertically on the surface of the NaY zeolite. The dynamic adsorption experiment of toluene showed that under humid conditions, NaY@LDHs exhibited a saturated adsorption capacity of 32.42 mg/g, representing a significant 87% increase compared to the parent NaY zeolite. The kinetic results show that the adsorption of toluene on NaY@LDHs is primarily physical adsorption, and other factors influence the adsorption process in addition to intraparticle diffusion. Therefore, the air layer formed by the LDHs shell on the surface of NaY zeolite imparts a hydrophobic effect, making NaY@LDHs a promising material for adsorbing volatile organic compounds in a wet environment.

Published: January 2024

International students’ social transition experiences are often discussed and researched in relation to their experiences on campus and with fellow students. However, international study also involves interactions and connections within students’ local communities beyond formal campus spaces. This paper reports on findings from a recent DAAD-funded research study which focused on the ways international students experience multicultural encounters within their local German communities, using photo-elicitation interviews with 45 students and 6 international office leaders. The study uses a sociological framing of “everyday multiculturalism”, which considered the everyday lived experiences of encountering cultural differences in small, mundane ways throughout our daily lives. The paper concludes with suggestions for practice, reflecting on the ways that DAAD and university staff might embed more holistic supports for international students’ community experiences.

Kekerasan terhadap perempuan adalah setiap tindakan berbasis gender yang dapat mengakibatkan penderitaan pada perempuan baik secara fisik, seksual, maupun mental. Perempuan sering menjadi golongan yang paling lemah sehingga rentan terhadap perilaku kekerasan oleh kaum lelaki. Data tahun 2023 dari KOMNAS perempuan menunjukkan bahwa tindakan kekerasan terhadap perempuan masih sangat tinggi yaitu 339.782 kasus selama tahun 2022. Angka ini lebih tinggi dibandingkan jumlah kasus tahun 2021. Data ini menunjukkan fakta bahwa tindakan kekerasan terhadap perempuan masing sangat besar. Kekerasan yang paling sering dialami oleh perempuan adalah kekerasan seksual, diikuti kekerasan fisik, dan kekerasan emosional. Tindakan kekerasan ini dipengaruhi oleh faktor budaya, ekonomi, sosial, dan kepribadian. Efeknya yang besar terhadap kesejahteraan hidup perempuan, memaksa dilakukannya tindakan pencegahan dan penanganan yang serius dengan kerjasama berbagai pihak yaitu keluarga, sekolah, lembaga pemerintah dan swasta, serta seluruh elemen masyarakat. Redefinisi konsep budaya tentang perempuan sebagai warga kelas dua perlu dilakukan secara serius. Perempuan memiliki hak dan martabat yang sama dengan kaum lelaki.

Published: January 2024

To support the energy transition and maintain the Green Port title, it is necessary to design a Solar Power Plant (PLTS) in the PT Pupuk Kalimantan Timur Port Office Building. In designing a PLTS system, a design analysis is needed that is appropriate to the roof capacity or roof area available on the building and the potential for solar radiation at that location. The stages carried out include selecting a PLTS system, selecting PLTS components, creating a PLTS design using the HelioScope simulator, and calculating investment feasibility. The results of this research show that there is potential for electricity production of 109.8 MWh per year with the construction of PLTS in the PT Pupuk Kalimantan Timur Port Office Building. The appropriate PLTS installation design is PLTS with an On-Grid system, consisting of 158 solar panels with a capacity of 540 Wp (Seraphim 540 BMA HV) and 1 inverter with a capacity of 100 kW (SUN 200–100KTL–M1). The installed capacity of PLTS is 85.3 kWp with a Performance Ratio of 79.6% and specific energy of 1,286.8 kWh/kWp. Investment in the construction of PLTS in the PT Pupuk Kalimantan Timur port office building is feasible with an investment value of IDR 872,515,500,-, IRR of 11.18% (IRR > WACC) and NPV of IDR 8,789,894.50 (NPV>0). The estimated return on capital can be carried out in the 7th year. It is hoped that this research can be a reference for the design and calculation of installing PLTS in the PT Pupuk Kalimantan Timur Port Office Building.

Grapes are grown on an area of 8.5 million hectares on Earth. Most of the world's grape production (60%) is located in the regions of Europe. The largest grape and wine-producing countries include France, Italy, and Spain. Viticulture in the Carpathian basin has a history of 2,000 years. The control of the Fetească regală variety which is a traditional Hungarian variety, the control reached the highest sugar content, with an exceptionally high value, and all three loaded treatments were significantly below this. The evolution of the acid content was exactly the opposite, the control reached the lowest value. In terms of survival, all load levels outperformed the control. In conclusion, in the case of Fetească regală, the bud load had both positive and negative effects on the content values, but it had only a positive influence in terms of yield. On the other hand, based on our observation, a high shoot density developed on the high-stressed stems in the plantation, which prevented the phytotechnical operations from being carried out.

ABSTRACT

 

The objective of the Student Work Program (KKM) activity is to enhance the capacity and skills of the Panamping Village community, Bandung sub-district, in managing the cultivation of Tilapia fish. The work program provides an opportunity for students to gain direct experience in the working world, allowing them to apply the theoretical knowledge acquired during their studies in a real working environment. This KKM activity is participated in by members of fish cultivation groups in the village who have a desire to improve their existing businesses. The challenges faced include the lack of knowledge and skills among the community regarding fish cultivation, especially in plastic ponds, and business planning. Additionally, there is a lack of implementation of good fish cultivation technologies, such as feeding practices, pre-stocking seedling management, all of which can affect fish growth. Moreover, there are no alternative fish rearing facilities, while the demand for tilapia fish is quite high. The method employed in this activity involves an approach that engages members of fish cultivation groups within the village. The implementation of the activity includes the direct provision of 2000 tilapia fish fingerlings. The results of this KKM activity have had a positive impact on the village.
Histological structures of the midguts of adult Rhipicephalus bursa and Rhipicephalus turanicus ticks (Acari: Ixodidae)

Published: January 2024

Ticks play a role in the natural cycle of approximately 200 pathogens and are responsible for the transmission of various pathogens, such as Babesia, Theileria, Borrelia, Rickettsia and Anaplasma, to humans and animals. The midgut of ticks is the first organ to come into contact with tick-borne pathogens during the blood meal. When pathogens are acquired from infected hosts via the blood meal, they are trapped in the lumen of the midgut. The structure and function of the midgut of ticks are very important for understanding the ecology and transmission of tick-borne pathogens; therefore, a more detailed and comprehensive understanding of their biology is required. To this end, this study examined the histomorphology of the midgut of Rhipicephalus bursa Canestrini and Fanzago and R. turanicus Pomerantzev using histological methods, for the first time from Türkiye. In both species, the midgut was found to consist of a pseudostratified epithelium surrounded by a thin muscular layer. However, within their epithelium there are different digestive cells, one of which is a stem cell and the others have different characteristics, such as having more or less granules in their cytoplasm and with a clear cytoplasm.

The progress of the Indonesian interior world is growing rapidly following current trends. Consumers tend to look for furniture with a simple, clean and functional style. One material that is often used for furniture is solid surface material. Solid surface can be combined with wood, iron, rattan and other materials. Considering the increasing number of solid surface manufacturers in Indonesia, competition in the solid surface industry is becoming tight. It requires strong repurchase interest from consumers to survive in the solid surface industry. This research was conducted to analyze the factors that influence solid surface consumers repurchase interest using PLS-SEM. The population of this research is consumers of solid surface performnite. The results of this research are that product quality, price perception, product variety have a significant effect on consumer satisfaction. Product quality, price perception, product variety have a significant effect on repurchase intention. Consumer satisfaction partially mediates the relationship between product quality, price perception, product variety and repurchase intention.

Ipomoea trifida G. Don (2n=2x=30) é considerada a ancestral silvestre mais próxima da batata- doce hexaploide [Ipomoea batatas (L.) Lam. (2n=6x=90] e seu genoma diploide é completamente sequenciado. Este estudo teve como objetivo mapear locos de herança quantitativa (QTL) em uma progênie de 210 irmãos completos de I. trifida, do cruzamento M9×M19 a partir de um mapa genético de alta densidade para a espécie baseado em polimorfismos de único nucleotídeo (SNPs) originados de genotipagem por sequenciamento (GBS). A avaliação fenotípica foi realizada para 188 progênies no Centro Internacional da Batata (CIP) em San Ramón, Peru, em 2016 e 2017, em casa-de-vegetação (delineamento em blocos completos casualizados, quatro repetições) e campo (em delineamento inteiramente casualizado, duas repetições), respectivamente. Os caracteres avaliados incluíram contorno, tipo e número de lóbulos da folha, forma do lóbulo central, número de folhas/planta medido em 12 dias, 30 dias e 58-62 dias, altura de planta medido em 11 dias e 30 dias, diâmetro dos entrenós da vinha, tamanho da folha madura, comprimento do pecíolo, número e peso fresco de raízes do tipo lápis, área foliar, pesos seco, fresco e número de raízes, pesos seco e fresco das vinhas, e superfície total de folhagem por unidade de área do solo. A análise de modelos mistos para cada experimento foi realizada no pacote R sommer v.4.1.2. Para 2016, as herdabilidades variaram de 0,37 a 0,80, e para 2017, as herdabilidades variaram de 0 a 0,43. Correlações em 2016 variaram de –0,37 a 1, e para 2017, de –0,26 a 0,97. Um mapa genético com 15 grupos de ligação e 6.410 SNPs, com comprimento total de 2440,47 cM, foi construído usando o pacote R Onemap v.3.0. Verificou-se a presença de erros de montagem nos cromossomos 2, 3 e 7. O mapeamento de QTL foi realizado usando a abordagem de mapeamento de intervalo composto para cada combinação ano-característica usando o pacote R fullsibQTL v.0.0.901. A procura de QTL foi realizada a cada 1 cM ajustando até dez cofatores por caráter. O tamanho da janela utilizado foi 20 cM, e 1.000 permutações foram realizadas para definir os limites de detecção do QTL a 5% de significância. Ao todo, 99 QTL foram encontrados com LOD score variando de 5,83 a 35,29. Espera-se que os resultados deste estudo possam auxiliar em futuros estudos de I. trifida e programas de melhoramento da batata-doce. Palavras-chave: SNP. Mapeamento por intervalo composto. QTL.

Proteomic profile of seminal plasma and spermatozoa of donkeys of the Pêga breed and its relationship with assisted reproduction
Authors:   , Costa Isabella Cristina Tolêdo Alves
Published: January 2024

Donkeys, along with their hybrids, mules and hinnies, resulting from breeding with mares, have a longstanding tradition of being used for labor-intensive tasks. Historically, these animals played pivotal roles in agriculture, warfare, trade, and transportation. However, with the advent of modernization, this dynamic has shifted. In Europe, these animals have become more popular as pets, and some species even faced the brink of extinction. In contrast, Brazil hosts a significant population of undomesticated donkeys, especially in the Northeast. Recently, the demand for donkeys has seen a resurgence, primarily in China, due to the consumption of their milk and meat. Assisted reproduction would be an advantageous approach, as it is more cost-effective and practical than maintaining animals in the field. However, when cryopreserved, donkey semen suffers a drastic decrease in its fertilization capabilities. The first chapter of this thesis delved into discerning the differences between the proteomic profiles of cryopreserved and non-cryopreserved sperm. In cryopreserved samples, proteins associated with infertility were identified, such as SERPINE2 and SERPINC1, both linked to the loss of sperm capacitation, and PLAU, associated with reduced motility. A high concentration of nucleoporins, related to neurodegenerative diseases, was also observed. In contrast, non-cryopreserved sperm displayed a proteomic profile primarily oriented towards energy production and metabolism, reflecting the energetic demands required for maintaining sperm motility and viability. In the second chapter, the proteomic profile of donkey seminal plasma was explored, emphasizing the identification of potential infertility biomarkers. Compared to existing literature, CRISP3 and HSP1 were identified, proteins previously linked to infertility in stallions. Also, CRISP1, PTP an PKA have potencial as biomarkers. The proteomic profile also highlighted proteins connected to energy production, metabolism, and reproduction, suggesting an influential role of seminal plasma proteins in sperm viability during the reproductive process of donkeys.
