Design and modeling of an integrated flywheel magnetic suspension for kinetic energy storage systems
The paper presents a novel configuration of an axial hybrid magnetic bearing (AHMB) for the suspension of steel flywheels applied in power-intensive energy storage systems. The combination of a permanent magnet (PM) with excited coil enables one to reduce the power consumption, to limit the system volume, and to apply an effective control in the presence of several types of disturbances. The electromagnetic design of the AHMB parts is carried out by parametric finite element analyses with the purpose to optimize the force performances as well as the winding inductance affecting the electrical supply rating and control capability. Such investigation considers both the temperature dependence of the PM properties and the magnetic saturation effects. The electrical parameters and the force characteristics are then implemented in a control scheme, reproducing the electromechanical behavior of the AHMB-flywheel system. The parameter tuning of the controllers is executed by a Matlab/Simulink code, examining the instantaneous profiles of both the air-gap length and the winding ampere-turns. The results of different dynamic tests are presented, evidencing the smooth air-gap changes and the optimized coil utilization, which are desirable features for a safe and efficient flywheel energy storage
Radon mitigation during the installation of the CUORE decay detector
CUORE - the Cryogenic Underground Observatory for Rare Events - is an
experiment searching for the neutrinoless double-beta () decay
of Te with an array of 988 TeO crystals operated as bolometers at
10 mK in a large dilution refrigerator. With this detector, we aim for a
Te decay half-life sensitivity of y
with 5 y of live time, and a background index of
counts/keV/kg/y. Making an effort to maintain radiopurity by minimizing the
bolometers' exposure to radon gas during their installation in the cryostat, we
perform all operations inside a dedicated cleanroom environment with a
controlled radon-reduced atmosphere. In this paper, we discuss the design and
performance of the CUORE Radon Abatement System and cleanroom, as well as a
system to monitor the radon level in real time.Comment: 10 pages, 6 figures, 1 tabl

Getting beyond peeing and pronouns: living non-binary gender in higher education
Non-binary people make up just over half the UK trans population and younger people are more likely to identify as non-binary than those over 35. Despite this increasing recognition, non-binary identities and experiences continue to be widely misunderstood. Similarly, if university trans inclusion policies focus solely on models of binary or medical transition, they will not fully address the needs of non-binary students. In the context of an increased focus on the participation and success of marginalized social groups in higher education, and a social and political backlash against equality, diversity and inclusion work, questions of how non-binary students thrive in universities are pressing. Non-binary inclusion and experiences in higher education have received little dedicated attention. This article draws on data from the largest survey to date of non-binary students in the United Kingdom and begins to fill those gaps. We highlight the prominence in the survey of issues around ‘peeing’ and ‘pronouns’ in the lived experiences of non-binary students and demonstrate the detrimental impact of the lack of recognition on students’ learning and lives at university. We conclude universities must get beyond ‘peeing and pronouns’ to reimagine higher education as an accessible and inclusive space

Identification of glyphosate-tolerant soybean plants through germination test
Objetivando reduzir o tempo necessário para verificar a presença do gene de tolerância ao herbicida glyphosate (RR), através da aplicação do produto em plantas de soja, ou o custo envolvido na verificação via análise de DNA, em sementes viáveis, realizou-se pesquisa para desenvolver metodologia para identificação de sementes de soja tolerantes a glyphosate em teste de germinação padrão. Foram usadas sementes de seis genótipos sensíveis a glyphosate e de 12 genótipos tolerantes. Os tratamentos foram: aplicação em pulverização cotiledonarlfoliar de solução de glyphosate, na concentração de 8960 mgll, em volume de 100 Ilha de calda (equivalente a 2 g/ha), no quinto dia do início do teste de germinação; aplicação de glyphosate na água de embebição do papel de germinação, nas concentrações de O, 280, 560, 1120,2240,4480,6720 e 8960 mgll. As unidades experimentais foram rolos de papel germiteste, contendo 50 sementes, com oito repetições, totalizando 400 sementes, exceto no tratamento de pulverização foliar, que foram 25 sementes em linha, semeadas no terço superior do papel de germinação. O papel de germinação foi pesado e acrescentou-se solução de glyphosate, nas concentrações estudadas, em volume equivalente a três vezes o peso do papel. O período de avaliação foi de oito dias. Os parâmetros avaliados foram a percentagem de plântulas normais, anormais e mortas. O estudo evidenciou que é possível identificar a presença de sementes de soja tolerantes a glyphosate (RR) pelo teste de germinação em laboratório e que a dose de glyphosate a ser usada no teste é 280 mg/l na água de embebição do substrato de germinação.Since DNA tests are relatively expensive and time-consuming for the detection of the presence of the gene in plant materiais confering glyphosate tolerance to soybean, an experiment was carried out with the objective of developing a rapid and simple laboratory test for identifying glyphosate-tolerant soybean seeds, through standard seed germination tests. Seeds from six susceptible and twelve glyphosate-tolerant genotypes were used. The treatments consisted of cotiledonar/foliar spray of a glyphosate solution at the concentration of 8960 mg/l with 100 Ilha spray volume (equivalent to 2 g/ha) on the fifth day from the beginning of the germination test and soaking of the germination paper with glyphosate solutions at the concentrations of 0, 280, 560, 1120,2240,4480,6720, and 8960 mgll. The experimental units consisted of roIled germtest paper containing 50 seeds, replicated 8 times, except for the foliar spray treatment where 25 seeds were lined on the first third ofthe germtest paper. The germtest paper was weighed and the glyphosate solutions were added according to the treatments, in volume equivalent to three times the paper weight. Percentage of normal, abnormal and dead seedlings was assessed for eight days, by which time germination had ceased. This research demonstrated that it is possible to detect the presence of glyphosate-tolerant soybean seeds by the lab germination test using glyphosate at the rate of280 mg!liter ofthe imbibition water.
