В статті проведено аналіз рухової діяльності людини. Встановлено, що управління скорочувальною активністю м'язової клітини здійснюється за допомогою мотонейронів - нервових клітин, тіла яких лежать в спинному мозку, а довгі відгалуження - аксони в складі рухового нерва підходять до м'язів, Біоелектричний вплив, переданий від центральної нервової системи до м'язів, відбивається підвищенням амплітуди в так званих рухових точках - місцях найбільшого скупчення рухомих одиниць. Якщо знімати біопотенціал в місцях розташування рухових точок, то ми можемо отримати вихідні сигнали для управління протезом. Електроміографією є основним методом дослідження нервово-м'язової системи за допомогою реєстрації біоелектричних потенціалів. Електро-міографічні дослідження показують, що амплітуди біопотенціалів варіюються від 5-10 мкВ (м'яз в стані спокою) до 500-1000 мкВ (м'яз в збудженому стані). Основний діапазон частот біопотенціалів, що реєструються поверхневими електродами, становить 20-200 Гц, з максимумом близьким 50 - 100 Гц. Запропоновано структурну схему управління біоелектричним протезом кисті.

Écologie et fiscalité : convergence des luttes ?
Authors: Ollivier-Trigalo Marianne 
Published: December 2019

Le projet de loi de Finances pour 2014 (PLF 2014) a introduit une composante carbone dans la Taxe intérieure sur la consommation des produits énergétiques (TICPE) – appelée aussi contribution climat énergie ou encore taxe carbone. L’inscription de cette mesure dans le PLF 2014 revient au gouvernement, qui s’appuie formellement sur les travaux d’un Comité pour la fiscalité écologique (CFE) sur lesquels nous nous sommes penchée afin d’appréhender dans quelles conditions l’introduction de l’assiette carbone dans la TICPE a été élaborée. Sur cette base empirique (nombreux écrits du CFE et entretiens réalisés auprès de membres du comité), l’objet de cet article est de mettre en lumière une interdépendance entre fiscalité et politique énergétique que donne à voir le résultat de ces travaux, concrétisé par le vote de la réforme de la TICPE. Notre analyse met en lumière comment les membres du CFE ont dû s’accommoder des règles et formats imposés par la fiscalité. Ces règles fiscales se retrouvent en effet dans le choix de passer par la TICPE qui répond à une double injonction : d’une part, l’injonction de rendement – une taxe est avant tout une recette ; d’autre part, l’injonction de ne pas créer de nouvelle taxe. Le choix de réformer la TICPE comporte plusieurs caractéristiques porteuses de sens de politique publique. La mobilisation d’un instrument fiscal a conduit à s’appuyer sur des arguments de basculement de la fiscalité – une transition fiscale. Dans le même temps, se concentrer sur la consommation des énergies fossiles en introduisant la prise en considération des émissions de CO2 (y compris des carburants) a induit des échanges sur la recherche de sobriété en énergie – une transition énergétique. Bien entendu, la réalité ne choisit pas, mais au contraire, mixe les deux orientations, les rendant interdépendantes.

L‘adoption des stratégies individuelles de lutte face au changement climatique est un enjeu majeur aussi bien sur le plan scientifique et environnemental que sur le plan sociétal. Cet article étudie dans quelle mesure les perceptions des populations ainsi que les contextes territoriaux peuvent être des barrières et/ou des leviers d’action face au changement du climat. La démarche s’appuie sur une étude comparée entre les communes de Lille et de Chauny, deux territoires proches sur le plan climatique, mais différents sur le plan géographique et socio-économique. Les résultats démontrent une diversité de perceptions et des stratégies de lutte que l’on peut attribuer à deux facteurs clés : le contexte géographique et les variables socioéconomiques des personnes enquêtées. Au niveau des perceptions du changement climatique, on constate une diversité liée au ressenti individuel des personnes enquêtées ; à leur niveau d’étude et à l’influence des principales sources d’information. Sur le plan des stratégies de lutte, des corrélations significatives existent entre les mesures adoptées et les niveaux de vie des populations enquêtées. Sur nos deux sites d’études, l’essentiel des mesures mises en avant va dans le sens de l’atténuation du changement climatique. Par ailleurs, le développement de ces actions d’atténuation est plus manifeste à Lille qu’à Chauny. Un des facteurs explicatifs de cette différence notable renvoie au contexte territorial et économique des deux sites.

Published: December 2019

A partir da LDB 9.394/96, que garante um ensino inclusivo com igualdade de condições, permanência e aprendizagem para todos os alunos, novos documentos surgiram como a Lei 10.436/2002, garantindo às pessoas com surdez o direito ao uso da Língua Brasileira de Sinais – Libras como meio legal de comunicação e expressão, necessitando, portanto, a oferta de uma educação bilíngue e capacitação de professores. O objetivo do presente estudo foi analisar as Propostas Pedagógicas dos cursos sobre surdez na formação continuada de professores do ensino fundamental e médio de uma Diretoria de Ensino de uma cidade do interior paulista. O estudo se definiu pela abordagem qualitativa utilizando como fonte de informações a análise documental dos arquivos da área de Educação Especial dessa Diretoria. Os resultados mostraram que foram oferecidos no período de 2003 a 2017, oito (8) cursos sendo 5 denominados Introdução à Língua Brasileira de Sinais- Libras e três (3) referentes a Curso Básico de Libras com uma carga horária de 30 horas teoria/prática, ministrados no período noturno, uma vez por semana durante três meses para um grupo de Diretores, Coordenadores Pedagógicos e Professores do Ensino Fundamental e Médio, somando 30 participantes em cada curso. Denotou-se uma insuficiência dos cursos voltados para essa área, destacando como pontos positivos a utilização de referenciais teóricos de grande reconhecimento, bem como uma série de materiais ilustrados para conduzir as aulas num contexto de dinamicidade visando reflexões sobre a perspectiva bilíngue na escola inclusiva.

Abstract. The present study investigates and compares the ground and in-flight
performance of three miniaturized aerosol absorption sensors integrated
on board small-sized Unmanned Aerial Systems (UASs). These sensors were
evaluated during two contrasted field campaigns performed at an urban site,
impacted mainly by local traffic and domestic wood burning sources (Athens,
Greece), and at a remote regional background site, impacted by long-range
transported sources including dust (Cyprus Atmospheric Observatory, Agia
Marina Xyliatou, Cyprus). The miniaturized sensors were first intercompared at the ground-level
against two commercially available instruments used as a reference. The
measured signal of the miniaturized sensors was converted into the
absorption coefficient and equivalent black carbon concentration (eBC). When
applicable, signal saturation corrections were applied, following the
suggestions of the manufacturers. The aerosol absorption sensors exhibited
similar behavior against the reference instruments during the two campaigns,
despite the diversity of the aerosol origin, chemical composition, sources,
and concentration levels. The deviation from the reference during both
campaigns concerning (eBC) mass was less than 8 %, while for the absorption
coefficient it was at least 15 %. This indicates that those sensors that
report black carbon mass are tuned and corrected to measure eBC more accurately than the absorption coefficient. The overall potential use of miniature aerosol absorption sensors on board
small UASs is also illustrated. UAS-based absorption measurements were used
to investigate the vertical distribution of eBC over Athens up to 1 km above
sea level during January 2016, exceeding the top of the planetary boundary
layer (PBL). Our results reveal a heterogeneous boundary layer concentration
of absorbing aerosol within the PBL intensified in the early morning hours
due to the concurrent peak traffic emissions at ground-level and the fast
development of the boundary layer. After the full development of the PBL,
homogenous concentrations are observed from 100 m a.g.l. to the PBL top.

Abstract. The majority of aerosol data are obtained from daytime measurements, and
there are few datasets available for studying nighttime aerosol
characteristics. In order to estimate the aerosol optical depth (AOD) and
the precipitable water vapor (PWV) during the nighttime using the moon as a
light source, a sky radiometer (POM-02, Prede Ltd., Japan) was modified. The
amplifier was adjusted so that POM-02 could measure lower levels of input
irradiance. In order to track the moon based on the calculated values, a
simplified formula was incorporated into the firmware. A new position sensor
with a four-quadrant detector to adjust the tracking of the Sun and moon was
also developed. The calibration constant, which is the sensor output for the
extraterrestrial solar and lunar irradiance at the mean Earth–Sun distance,
was determined by using the Langley method. The measurements for the Langley
calibration were conducted at the National Oceanic and Atmospheric
Administration/Mauna Loa Observatory (NOAA/MLO) from 28 September 2017 to
7 November 2017. By assuming that the correct reflectance is proportional to the
reflectance estimated by the Robotic Lunar Observatory (ROLO) irradiance
model, the calibration constant for the lunar direct irradiance was
successfully determined using the Langley method. The ratio of the
calibration constant for the moon to that of the Sun was often greater than
1; the value of the ratio was 0.95 to 1.18 in the visible and near-infrared
wavelength regions. This indicates that the ROLO model often underestimates
the reflectance. In addition, this ratio depended on the phase angle. In
this study, this ratio was approximated by a quadratic equation of the phase
angle. By using this approximation, the reflectance of the moon can be
calculated to within an accuracy of 1 % or less. In order to validate the estimates of the AOD and PWV, continuous
measurements with POM-02 were conducted at the Japan Meteorological
Agency/Meteorological Research Institute (JMA/MRI) from January 2018 to May 2018,
and the AOD and PWV were estimated. The results were compared with the
AOD and PWV obtained by independent methods. The AOD was compared with that
estimated by the National Institute for Environmental Studies (NIES) High
Spectral Resolution Lidar measurements (wavelength: 532 nm), and the PWV was
compared with the PWV obtained from a radiosonde and the Global Positioning
System. In addition, the continuity of the AOD (PWV) before and after
sunrise and sunset in Tsukuba was examined, and the AOD (PWV) of AERONET and
that of POM-02 at MLO were compared. In the results, the daytime and
nighttime AOD (PWV) measurements are shown to be statistically almost
equivalent. The AODs (PWVs) during the daytime and nighttime for POM-02 are
presumed to have the same degree of precision and accuracy within the
measurement uncertainty.

Published: December 2019

Context.—
Bilateral mastectomy for chest masculinization is one of the gender-affirming procedures for transmasculine individuals.

Objective.—
To optimize gross handling protocols and assess histopathologic findings in transmasculine breast tissue specimens.

Design.—
We identified all gender-affirming mastectomies from 2015 to 2018. We sequentially identified reduction mammoplasty (RM) cases for macromastia from the same period as control. Significant findings were defined as atypical ductal or lobular hyperplasia (ADH, ALH), ductal or lobular carcinoma in situ (DCIS, LCIS), or invasive carcinoma.

Results.—
Significant findings were present in 6 of 211 gender-affirming mastectomies (2.8%) as follows: ADH (n = 5) and LCIS together with ALH (n = 1). By comparison, 19 of 273 RM specimens (7%) yielded significant findings as follows: ALH (n = 11), ADH (n = 4), LCIS (n = 2), DCIS (n = 1), and invasive lobular carcinoma (n = 1). In the gender-affirming group, 142 transmen underwent androgen therapy before surgery, of whom 2 had significant pathologic findings. Thirty and 41 individuals had a family history of breast cancer in the gender-affirming and RM group, of whom 1 and 3 individuals had significant pathologic findings, respectively.

Conclusions.—
Our study demonstrates that we handle transmasculine mastectomy specimens by examining 2.8 times more slides on average than for RMs, with a 2.5 times lower rate of significant pathologic findings. Prior family history of breast cancer or the use of androgen therapy before surgery in gender-affirming individuals did not increase the risk of identifying significant breast lesions. We recommend submitting 4 tissue blocks per mastectomy for individuals undergoing gender-affirming breast surgery.
Post-natal development of EEG responses to noxious stimulation in pigs (Sus scrofa) aged 1-15 days

Published: December 2019

AbstractThis study examined electroencephalographic (EEG) indices of acute nociception in pigs (Sus scrofa) aged 1, 5, 7, 10, 12 and 15 days, post-natal. Ten pigs per age were anaesthetised with halothane in oxygen and maintained at a light plane of anaesthesia. EEG was recorded bilaterally using a five-electrode montage. Following a 10-min baseline period, tails were docked using side-cutter pliers and recording continued for a further 5 min. Changes in the median frequency (F50), 95% spectral edge frequency (F95) and total power (PTOT) of the EEG were used to assess nociception. Tail-docking at one day of age induced no significant changes in the EEG spectrum. A typical nociceptive response, characterised by an increase in F50 and decrease in PTOT was evident at ten days of age, with five and seven day old pigs exhibiting responses in either F50 or PTOT only. Pooling of data into ≤ 7 days of age and > 7 days of age revealed F50 was higher overall in the older group. Whilst PTOT decreased after docking in both groups, this response was larger and more prolonged in the older group. F95 increased after docking in the older pigs only. Overall, these data provide evidence of an increase in cortical responsiveness to noxious stimulation with increasing post-natal age, suggesting there may be qualitative differences in pain perception between age groups. Further, the data provide some support for current recommendations that tail-docking and other painful husbandry procedures be performed within seven days of birth in order to minimise their impact on animal welfare.
Redefining human-animal relationships: an evaluation of methods to allow their empirical measurement in zoos
Authors: Patel F , Whitehouse-Tedd K , Ward SJ 
Published: December 2019

AbstractScientific studies of human-animal interactions (HAIs) and how these develop into human-animal relationships (HARs) now represent some of the most significant contributions to animal welfare science. However, due to the current definition of HAR, studies have only been able to measure HAIs and infer its impact on HARs and animal welfare. Here, we redefine HARs as a series of repeated HAIs between two individuals known to each other, the nature of which is influenced by their historical HAIs and where consideration to the content, quality and the pattern of the interactions is also vital. With a new definition, it is now feasible to empirically measure HARs, however, first, it is important to evaluate current methods utilised in animal industries to allow standardisation across HAR research in zoos. Here, we review the current methods that have been used to assess HAIs in animals and determine their overall suitability for measuring HARs and their use in a zoo environment. Literature searches were conducted using the search terms ‘human-animal’ AND ‘interaction’, ‘human-animal’ AND ‘relationship’, ‘human-animal’ AND ‘bond’. Subsequently, ‘zoo’, ‘companion’, ‘agriculture’, ‘laboratory’ and ‘wild’ were added to each combination yielding five potential methods to evaluate. These methods were assessed according to a panel of indicators including reliability, robustness, practical application and feasibility for use in a zoo environment. Results indicated that the methods utilising ‘latency’, ‘qualitative behaviour assessment’ and the ‘voluntary approach test’ were potentially viable to assess HARs in a zoo environment and could subsequently contribute to the assessment of welfare implications of these HARs for the animals involved. These methods now require empirical testing and comparisons within a zoo environment.
