From mechanics to thermodynamics of hexameric molecular motors
Publication . Pessoa, Victor Hugo de Mello; Sartori, Pablo
"Molecular motors are protein assemblies that convert chemical energy into motion.
This energy conversion can be understood as a transfer between chemical and mechanical
processes, mediated by highly orchestrated conformational changes in protein
structure. These motors are indispensable for all forms of life, sustaining both their
metabolism and spatial organisation. Among them, hexameric ATPases form a broad
and diverse group of molecular machines that play central roles in protein and DNA
manipulation. Despite major advances in biochemistry, biophysics, and structural
biology, the link between conformational changes and energy processing in these proteins
remains poorly understood. This thesis aims to address this gap by integrating
data from protein structures with novel interdisciplinary analytical tools.(...)"

Este artigo propõe que “A Metamorfose”, de Franz Kafka,se constrói em torno de uma sequência motivada de enquadramentos, ou retratos emoldurados, que admite ser lida como um fotolivro avant la lettre. Dessa leitura emerge um tema recorrente, a metalepse, por via do qual Kafka engendra uma leitura psicanalítica do seu próprio texto, que visa sabotar a sua interpretação. Tal procedimento codifica um característico padrão evasivo e uma alegoria do acto da escrita figurada no corpo e nos movimentos de Gregor Samsa. This articleproposes thatFranz Kafka’s “The Metamorphosis”is built on a moti-vated sequence of frames, or framed portraits, which reads as a photobook avant la lettre. From this reading a recurring theme emerges, metalepsis, through which Kafka engenders a psychoanalytic reading of his own text, which aims to sabotage its interpretation. This codifies a characteristic evasive pattern and an allegory of the act of writing for which Gregor Samsa’s body and movements are a trope.
Ulta beauty: global expansion as the key to growth
Publication . Contente, Beatriz Silva; André, Rosário
This report evaluates Ulta Beauty, Inc., a leading U.S. specialty beauty retailer, to determine whether the company represents an attractive investment opportunity at current market valuations. The analysis examines Ulta’s business model, competitive positioning, financial performance, and long-term growth prospects. Using historical financial analysis, peer comparison and valuation methodologies, specifically the Adjusted Present Value (APV) and multiple-based valuation, this report estimates Ulta’s intrinsic value and downside risks. Overall, with a WACC of 9.4% and a terminal growth rate of 4.3%, we estimate a target price of $859 per share for FY2026, implying approximately 43% upside from the reference price and supporting a Buy recommendation
Fotografia e História da Educação
Publication . Cabeleira, Helena Margarida dos Reis; Faculdade de Ciências Sociais e Humanas (FCSH); Universidade Estadual de Maringá
O artigo discute o papel da fotografia enquanto fonte e objeto de investigação em História da Educação e o seu contributo para o estudo das instituições, práticas e cultura material da escola. Procura-se identificar e analisar algumas questões conceptuais e metodológicas envolvidas no uso de imagens enquanto documentos e monumentos históricos, bem como enquanto artefactos dotados de especificidades próprias, destacando os desafios e as potencialidades do seu uso e teorização nas Ciências Sociais, Artes e Humanidades Digitais. Serão apresentados e discutidos exemplos de publicações ou projetos de investigação que, nas últimas duas décadas, contribuíram para a criação, digitalização e divulgação de acervos ou arquivos fotográficos para o ensino e a investigação no contexto Luso-Brasileiro. The article discusses the role of photography as sourceand objectof research in the History of Education, and its contribution to the study of institutions, practices and the material culture of school. It seeks to identify and analyze conceptual and methodological issues involved in the use of images as historical documentsand monuments, and as artifacts endowed with their own specificities, highlighting the challenges and potentialities of their use and theorization in the Social Sciences, Arts and Digital Humanities. Examples of publications or research projects that, in the past two decades, contributed to the creation, digitalization and dissemination of photographic collections or archives for teaching and research in the Luso-Brazilian context, will be presented and discussed.
The BPI case: governance and valuation under caixabank's takeover offer
Publication . Ferreira, Madalena Venda; Pinho, Paulo Soares de
This case study, supported by the corresponding teaching notes, explores the takeover of Banco Português de Investimento (BPI) by CaixaBank, controlled by La Caixa. Focusing on valuation and governance, it follows BPI’s history of failed mergers, ownership fights, and structural flaws that made the bank more susceptible to acquisition. It underscores the bank’s small size, inefficiency, and the increasingly concentrated control held by La Caixa, which raises doubts about the reasonableness of the acquisition price. These topics form a base on which banking consolidation, valuation in small financial markets and governance implications of cross-border transactions can be discussed.
