Towards an ethics of denaturalization: Nudity in the theatre of Marcio Abreu
Este ensaio pretende investigar a nudez no teatro de Marcio Abreu e da companhia brasileira de teatro como estratégia crítica para desestabilizar comportamentos naturalizados no teatro. As peças Descartes com lentes, Isso te interessa?, PROJETO bRASIL e Nós serão brevemente abordadas como exemplos em que a nudez aparece como artifício de elaboração formal que pode convocar o corpo do espectador à presença e à atenção e sua mente a elaborar sobre as coisas do teatro e sobre as coisas do mundo.This paper intends to investigate nudity in the theatre of Marcio Abreu and companhia brasileira de teatro as a critical strategy to destabilize naturalized behaviors in the theatre. Four plays – Descartes com lentes, Isso te interessa?, PROJETO bRASIL and Nós – will be briefly analyzed as examples of how nudity is used as an artifice of formal elaboration which may summon the spectator’s body to an estate of presence and attention and summon their mind to elaborate on theatre and consequently on the world

Repetição e diferença: dispositivos e mediações no teatro de Christiane Jatahy
The article concerns the work of Brazilian stage director ChristianeJatahy in five performances (four theatre plays and an opera), aimingto analyze her stagings regarding the ideas of system, device, mediationand repetition. Through an investigation of her dramaturgical operations,I try to identify procedures adopted to destabilize repetitionin the theatre, such as the creation of counter-devices, the work withsystems in the creative process of a scenic dramaturgy that is alsoan actor’s dramaturgy, as well as the relation between theatre andcinema.O artigo aborda o trabalho da encenadora brasileira Christiane Jatahyem cinco espetáculos (quatro peças de teatro e uma ópera), com o propósitode analisar as encenações a partir das ideias de sistema, dispositivo,mediação e repetição. Através da análise de suas operaçõesdramatúrgicas, procuramos identificar procedimentos adotados como objetivo de desestabilizar a repetição no teatro, como a criação decontradispositivos, o trabalho com os sistemas para a criação de umadramaturgia cênica e atorial, além da relação entre teatro e cinema
Human Alignment of Large Language Models through Online Preference Optimisation
Ensuring alignment of language models' outputs with human preferences is
critical to guarantee a useful, safe, and pleasant user experience. Thus, human
alignment has been extensively studied recently and several methods such as
Reinforcement Learning from Human Feedback (RLHF), Direct Policy Optimisation
(DPO) and Sequence Likelihood Calibration (SLiC) have emerged. In this paper,
our contribution is two-fold. First, we show the equivalence between two recent
alignment methods, namely Identity Policy Optimisation (IPO) and Nash Mirror
Descent (Nash-MD). Second, we introduce a generalisation of IPO, named IPO-MD,
that leverages the regularised sampling approach proposed by Nash-MD.
This equivalence may seem surprising at first sight, since IPO is an offline
method whereas Nash-MD is an online method using a preference model. However,
this equivalence can be proven when we consider the online version of IPO, that
is when both generations are sampled by the online policy and annotated by a
trained preference model. Optimising the IPO loss with such a stream of data
becomes then equivalent to finding the Nash equilibrium of the preference model
through self-play. Building on this equivalence, we introduce the IPO-MD
algorithm that generates data with a mixture policy (between the online and
reference policy) similarly as the general Nash-MD algorithm. We compare
online-IPO and IPO-MD to different online versions of existing losses on
preference data such as DPO and SLiC on a summarisation task

INFLUENCE OF SUBSTRATE AND CONTAINER VOLUME ON THE QUALITY OF Cabralea canjerana (Vell.) Mart. SEEDLINGS IN NURSERY AND FIELD
A utiliza\ue7\ue3o de mudas de qualidade \ue9 fundamental para o
estabelecimento de plantios florestais, o que \ue9 alcan\ue7ado por
meio de t\ue9cnicas adequadas desde a fase de viveiro. Assim, este
trabalho teve por objetivo investigar a influ\ueancia de diferentes
composi\ue7\uf5es de substratos e do volume de recipiente (tubetes)
no crescimento de mudas de canjerana ( Cabralea canjerana ), no
viveiro e no campo. Em viveiro foram avaliadas tr\ueas
composi\ue7\uf5es de substratos \ue0 base de turfa (100% turfa,
turfa + 20% casca de arroz carbonizada (CAC) e turfa + 40% CAC)
combinadas com dois tamanhos de tubetes (100 e 280 cm3). Foram
realizadas mensalmente, durante 330 dias, mensura\ue7\uf5es do
di\ue2metro do coleto (DC) e da altura (H), e foi calculada
tamb\ue9m a rela\ue7\ue3o H/DC. Aos 330 dias foram avaliadas as
massas secas radicular, a\ue9rea e total e o \uedndice de qualidade
de Dickson. Os mesmos tratamentos foram avaliados em campo, durante um
per\uedodo de 360 dias, e foi mensurado a cada 90 dias, o DC e a H, e
calculada a H/DC. No viveiro e em campo, os experimentos foram
conduzidos com delineamento experimental de blocos ao acaso, com quatro
repeti\ue7\uf5es. Mudas de canjerana podem ser produzidas em
substrato composto por 60% de turfa e 40% de casca de arroz carbonizada
sem preju\uedzo do seu crescimento em campo, tendo em vista a
economia que representa no viveiro. O uso do tubete de 280 cm3
proporcionou somente crescimento superior das mudas na fase de plantio,
sendo que o di\ue2metro do coleto e a massa seca radicular
expressaram o melhor desempenho.The use of quality seedlings is essential for the establishment of
forest plantations, which is achieved through the use of appropriate
techniques from the nursery. Thus, this study aimed to investigate the
influence of substrate composition and volume of container (tubes) in
the growth of seedlings of canjerana ( Cabralea canjerana ), in the
nursery and field. In nursery, three compositions of peat substrates
were evaluated (100% peat, peat + 20% rice hulls (RH) and peat + 40%
RH) and combined with two sizes of containers (100 and 280 cm3).
Measurements of root collar diameter (DC) and height (H) were performed
monthly during 330 days, and the ratio H/DC was also calculated. At 330
days, the root, air and total dry masses and Dickson\u2019s quality
index were assessed. The same treatments were evaluated in the field
during a period of 360 days and DC and H were measured and H/DC was
calculated in every 90-day period. In the nursery and field experiments
were carried out with experimental design of random blocks, with four
replications. Seedlings of canjerana can be produced in a substrate
composed of 60% peat and 40% of rice hulls without harming its growth
in the field, with a view that the economy is in nursery. The tube of
the tube in the size 280 cm3 only provided superior growth of seedlings
during the field phase, where seedlings produced in these containers
expressed a better performance in relation to root collar diameter and
root dry mass

Affinity purification of bacterial outer membrane vesicles (OMVs) utilizing a His-tag mutant
To facilitate the rapid purification of bacterial outer membrane vesicles (OMVs), we developed two plasmid constructs that utilize a truncated, transmembrane protein to present an exterior histidine repeat sequence. We chose OmpA, a highly abundant porin protein, as the protein scaffold and utilized the lac promoter to allow for inducible control of the epitope-presenting construct. OMVs containing mutant OmpA-His6 were purified directly from Escherichia coli culture media on an immobilized metal affinity chromatography (IMAC) Ni-NTA resin. This enabling technology can be combined with other molecular tools directed at OMV packaging to facilitate the separation of modified/cargo-loaded OMV from their wt counterparts. In addition to numerous applications in the pharmaceutical and environmental remediation industries, this technology can be utilized to enhance basic research capabilities in the area of elucidating endogenous OMV function
Acidente botrópico em um canino: abordagem terapêutica – relato de caso / Botropic accident in a canine: therapeutic approach – case report
Acidentes com a serpente do gênero Bothrops são muito comuns em animais de companhia, devido a agressividade destas serpentes e a curiosidade dos pequenos animais, principalmente caninos. Estes animais peçonhentos possuem uma toxina que produz um efeito anticoagulante, vasculotóxico e nefrotóxico causando sinais clínicos graves em animais de companhia. Este trabalho tem como objetivo relatar um acidente botrópico em um canino fêmea sem raça definida, de dez anos de idade, pesando 19kg, apresentando sangramento na cavidade oral e dispneia. Logo no atendimento emergencial foi coletado exames de sangue e, ao eritrograma, evidenciou-se considerável trombocitopenia. Inicialmente foi realizado terapia de suporte com oxigenioterapia e fluidoterapia. Foi administrado soro antiofídico polivalente, sendo este essencial para melhora do quadro do paciente. Além disso, foi administrado analgésicos devido alto grau de algia do paciente. A antibioticoterapia realizada também foi indispensável no tratamento devido áreas necrosadas causadas pela picada, além de infecções secundárias. A administração de corticosteroides e pré infusão de soro antiofídico reduz reações imediatas, como dispneia, tosses, náuseas, pruridos e urticaria. Pode se concluir que a conduta clínica e terapêutica utilizada, baseada nos sinais clínicos apresentados e resultados de exames de sangue mostrou-se eficiente. O soro antiofídico polivalente foi capaz de neutralizar o veneno inoculado e a associação terapêutica utilizada foi fundamental para a melhora significativa do animal.
