Bibliófilas, sim! Breves apontamentos sobre duas bibliotecas de mulheres brasileiras: Women Collectors, yes! Brief notes on two Brazilian Women´´ s Libraries

ResumoO colecionismo de livros por mulheres é a tônica deste artigo. Para tanto, foram feitas reflexões à luz de autores, como: Quentin-Bauchart (1886), Roberts (1895), Cim (1901), Darnton (1992), Courceles e Júlian (1999), Azevedo (2010), Palma Peña (2013), Bessone (2014), Hastings (2014) e Melo (2018). Do ponto de vista metodológico, foi realizado o estudo de dois casos: a bibliófila paraense Annunciada Chaves e a bibliófila gaúcha Salete Maccalóz, cujas trajetórias serão analisadas segundo os seguintes aspectos: do nascimento e morte; formação; inserção social e interesse pelos livros até o destino de suas bibliotecas; características de suas bibliotecas, ilustrando peculiaridades bibliofílicas. Para conclusão, nosso objetivo é modesto, qual seja, contribuir para expandir de algum modo a temática no sentido de a não causar tanto estranhamento, a termos como: “Bibliófila”; “Biblioteca de Mulher”; “Mulheres e Colecionismo” etc. Palavras-chave: Bibliofilia feminina. Colecionismo. Patrimônio bibliográfico. AbstractThe collection of books by women is the keynote of this article. For this, reflections were made in the light of authors, such as: Quentin-Bauchart (1886), Roberts (1895), Cim (1901), Darnton (1992), Courceles and Júlian (1999), Azevedo (2010), Palma Peña (2013), Bessone (2014), Hastings (2014) and Melo (2018). From a methodological point of view, the study of two cases was carried out: the Paraense bibliophile Annunciada Chaves and the Gaúcha bibliographer Salete Maccalóz, whose trajectories will be analyzed according to the following aspects: from birth and death, training, social insertion and interest in books until the destination of their libraries, characteristics of their libraries, illustrating the bibliographic characteristics. In conclusion, our objective is modest, that is, to contribute to expand the theme in some way so as not to cause such strangeness as words: “Bibliophile”; “Women's Library”; “Women and Collecting” etc. Keywords: Women Collectors.

Cadmium uptake, translocation and tolerance in the hyperaccumulator Arabidopsis halleri

Arabidopsis halleri is a well-known zinc (Zn) hyperaccumulator, but its status as a cadmium (Cd) hyperaccumulator is less certain. Here, we investigated whether A. halleri can hyperaccumulate Cd and whether Cd is transported via the Zn pathway. Growth and Cd and Zn uptake were determined in hydroponic experiments with different Cd and Zn concentrations. Short-term uptake and root-to-shoot transport were measured with radioactive Cd-109 and Zn-65 labelling. A. halleri accumulated > 1000 mg Cd kg(-1) in shoot dry weight at external Cd concentrations >= 5 mu m>, but the short-term uptake rate of Cd-109 was much lower than that of Zn-65. Zinc inhibited short-term Cd-109 uptake kinetics and root-to-shoot translocation, as well as long-term Cd accumulation in shoots. Uptake of Cd-109 and Zn-65 were up-regulated, respectively, by low iron (Fe) or Zn status. A. halleri was much less tolerant to Cd than to Zn. We conclude that A. halleri is able to hyperaccumulate Cd partly, at least, through the Zn pathway, but the mechanisms responsible for cellular Zn tolerance cannot detoxify Cd effectively

Domestic dogs (Canis familiaris) grieve over the loss of a conspecific.

Behavioural reactions towards a dead conspecific have been observed rarely in wild canids and there is no documented scientific evidence of grief in pet dogs. A quantitative analysis of grief-related responses in both dogs and owners was conducted, using the validated online Mourning Dog Questionnaire. The survey was completed by 426 Italian adults who had owned at least two dogs, one of whom died while the other was still alive. This research aims to explore whether, how and what a dog may experience over the loss of a companion dog. Multiple logistic regression indicates that both a friendly or parental relationship between two dogs but also the fact that dogs used to share food and the owner's grief and anger are principal predictors of negative behavioural changes. According to dog owners' answers, the surviving dog after the death of the companion dog changed both in terms of activities ("playing", "sleeping", and "eating") and emotions (fearfulness), which occurred as a function of the quality of the relationship between the two animals. By contrast, the time the two dogs had spent together had no effect on the behaviours of surviving dog. Owner perceptions about their dog's reactions and emotions were not related to the memory or suffering of the event that tended to diminish over time. These findings indicate that a dog may show grief-related behavioural and emotional patterns when a close conspecific dies, with aspects of the latter possibly related to the owner's emotional status

Abordagem teórico-reflexiva da estratégia de ensino 4E X 2 e sua interface com a Teoria Metacognitiva

Ensaio teórico reflexivo sobre a abordagem metacognitiva de uma estratégia de ensino. 4E X 2 corresponde a uma proposta de instrução por investigação criada por pesquisadores da Clemson University College Education nos EUA na qual 4E significa: Engajar, Explorar, Explicar e Estender e o X2, significa Avaliar e Refletir. O objetivo deste trabalho é apresentar e descrever a 4E X 2 e relacionar seus procedimentos e constructos com a teoria e estratégias de ensino metacognitivo. A descrição detalhada dos procedimentos de aplicação da estratégia fornece subsídios para sua utilização por professores do ensino básico, enquanto sua análise explicita a conexão com a teoria metacognitiva e estratégias de ensino metacognitivas. Observamos aspectos positivos na forma pragmática como os templates e protocolos são apresentados, verificamos interfaces entre a estratégia e as componentes conhecimento do conhecimento e do controle executivo autorregulador, assim como, os procedimentos de aplicação apresentam-se compatíveis com as definições das funções das estratégias de ensino metacognitivo. Este estudo reforça a importância da aproximação da produção do contexto acadêmico com o ambiente escolar, onde o principal objetivo sempre será a reprodução possível destas teorias na prática do dia a dia do professor

The holographic principle

There is strong evidence that the area of any surface limits the information content of adjacent spacetime regions, at 10^(69) bits per square meter. We review the developments that have led to the recognition of this entropy bound, placing special emphasis on the quantum properties of black holes. The construction of light-sheets, which associate relevant spacetime regions to any given surface, is discussed in detail. We explain how the bound is tested and demonstrate its validity in a wide range of examples. A universal relation between geometry and information is thus uncovered. It has yet to be explained. The holographic principle asserts that its origin must lie in the number of fundamental degrees of freedom involved in a unified description of spacetime and matter. It must be manifest in an underlying quantum theory of gravity. We survey some successes and challenges in implementing the holographic principle.Comment: 52 pages, 10 figures, invited review for Rev. Mod. Phys; v2: reference adde

Traços de personalidade e comportamentos agressivos: O papel mediador da vingança

This study aims to verify the mediating role of revenge in the relationship between personality traits and aggression. The participation of 218 people, aged between 18 and 69 years (M=27.84; SD=10.37), mostly female and with incomplete higher education. Participants responded to the Big Five inventory, Buss-Perry aggression questionnaire and revenge scale. As a result, only kindness and neuroticism showed significant correlations with aggression factors and revenge. Regarding mediation, in kindness it was observed that the models of mediation are not adjusted to the data for physical, verbal aggression and hostility; In neuroticism, there was a partial mediation in all types of aggression. It is understood that the results contribute to the understanding of what mechanisms underlie aggressive behaviors, especially when taking into account personality traits and vengeful attitudes.Este estudo tem por objetivo verificar o papel mediador da vingança na relação entre traços de personalidade e agressão. Contou-se com a participação de 218 pessoas, com idades entre 18 e 69 anos (M=27,84; DP=10,37), a maioria do sexo feminino e com ensino superior incompleto. Os participantes responderam ao inventário dos Big Five, questionário de agressão Buss-Perry e escala de vingança. Como resultados, apenas a amabilidade e o neuroticismo apresentaram correlações significativas com os fatores da agressão e com a vingança. Acerca dos modelos de mediação, o modelo da amabilidade não obteve um bom ajuste de dados para predizer a agressão física, agressão verbal e hostilidade; para o neuroticismo, houve uma mediação parcial em todos os tipos de agressão. Entende-se que os resultados contribuem para a compreensão de quais mecanismos estão subjacentes aos comportamentos agressivos, sobretudo quando se leva em conta os traços de personalidade e as atitudes vingativas

Giant primary adrenal hydatid cyst presenting with arterial hypertension: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>A primary hydatid cyst of the adrenal gland is still an exceptional localization. The adrenal gland is an uncommon site even in Morocco, where echinococcal disease is endemic.</p> <p>Case presentation</p> <p>We report the case of a 64-year-old Moroccan man who presented with the unusual symptom of arterial hypertension associated with left flank pain. Computed tomography showed a cystic mass of his left adrenal gland with daughter cysts filing the lesion (Type III). Despite his negative serology tests, the diagnosis of a hydatid cyst was confirmed on surgical examination. Our patient underwent surgical excision of his left adrenal gland with normalization of blood pressure. No recurrence has occurred after 36 months of follow-up.</p> <p>Conclusion</p> <p>There are two remarkable characteristics of this case report; the first is the unusual location of the cyst, the second is the association of an adrenal hydatid cyst with arterial hypertension, which has rarely been reported in the literature.</p
