Interiors and furnishings designed by Miguel Fisac for the CSIC
[ES] Conocida y fotografiada parte de la producción de Miguel Fisac relacionada con el mobiliario para el CSIC, no había sido estudiada hasta ahora en su conjunto. Se recogen cronológicamente los diferentes estilos utilizados para los distintos espacios, las motivaciones expresadas por el propio arquitecto, su estado actual y las consideraciones que puedan permitir su inclusión en el Patrimonio Artístico del CSIC y la declaración de alguna de ellas, como la “librería científica” como Bien de Interés Cultural.[EN] Although Miguel Fisac’s designs for the furnishings in the Spanish Council for Scientific Research are well known and widely photographed, they had not, to date, been studied as a whole. This chronological review of the styles used to create different spatial effects describes both the author’s motivations as explained by the architect himself and the present condition of the furnishings. Considerations in support of their inclusion in the Council’s Artistic Estate are discussed, advocating —in the case of the “Scientific Library”— the award of Asset of Cultural Interest status.Peer reviewe
Перспективы нефтегазоносности нижнеюрских резервуаров на основе комплексной интерпретации данных геотермии и бурения в Нюрольской мегавпадине (Томская область)
Объектом исследования является нефтематеринская тогурская свита и резервуары нижнеюрского нефтегазоносного комплекса.
Цель работы – выполнение оценки перспектив нефтегазоносности нижнеюрских отложений Нюрольской мегавпадины на базе палеотектонических реконструкций и палеотемпературного моделирования, картирование плотности первично-аккумулированных тогурских нефтей, определение первоочередных объектов для постановки геолого-разведочных работ.
Работа выполнена на основе геолого-геофизических данных, полученных при бурении глубоких скважин и лабораторных исследований керна с использованием публикаций по теме исследования и фондовым материалам.Object of research is the oil source togur suit and Lower Jurassic oil and gas oil and gas bearing complex.
Work objective is to estimate lower Jurassic oil and gas potential of Nurolka mega depression using paleotectonic reconstructions and modeling, mapping of initially accumulated oil resources containing in togurskaya suit, determining premium objects for geological exploration.
During research we analyzed publications and library materials. Geological and geophysical data obtained by well drilling and core analysis were also systematized and used in that work
Chronic Multi-Electrode Electromyography in Snakes
Knowledge about body motion kinematics and underlying muscle contraction dynamics usually derives from electromyographic (EMG) recordings. However, acquisition of such signals in snakes is challenging because electrodes either attached to or implanted beneath the skin may unintentionally be removed by force or friction caused from undulatory motion, thus severely impeding chronic EMG recordings. Here, we present a reliable method for stable subdermal implantation of up to eight bipolar electrodes above the target muscles. The mechanical stability of the inserted electrodes and the overnight coverage of the snake body with a sleeping bag ensured the recording of reliable and robust chronic EMG activity. The utility of the technique was verified by daily acquisition of high signal-to-noise activity from all target sites over four consecutive days during stimulus-evoked postural reactions in Amazon tree boas and Western diamondback rattlesnakes. The successful demonstration of the chronic recording suggests that this technique can improve acute experiments by enabling the collection of larger data sets from single individuals
Distributed delays stabilize neural feedback systems
We consider the effect of distributed delays in neural feedback systems. The
avian optic tectum is reciprocally connected with the nucleus isthmi.
Extracellular stimulation combined with intracellular recordings reveal a range
of signal delays from 4 to 9 ms between isthmotectal elements. This observation
together with prior mathematical analysis concerning the influence of a delay
distribution on system dynamics raises the question whether a broad delay
distribution can impact the dynamics of neural feedback loops. For a system of
reciprocally connected model neurons, we found that distributed delays enhance
system stability in the following sense. With increased distribution of delays,
the system converges faster to a fixed point and converges slower toward a
limit cycle. Further, the introduction of distributed delays leads to an
increased range of the average delay value for which the system's equilibrium
point is stable. The enhancement of stability with increasing delay
distribution is caused by the introduction of smaller delays rather than the
distribution per se.Comment: 7 pages, 4 figure
Перспективные направления и проблемные вопросы стратегического партнерства России, Монголии и Китая во внешнеэкономической и таможенной сфере
В силу исторических и геополитических традиций и тенденций развития Россия, Монголия и Китай на протяжении длительного периода являются стратегическими партнерами в сфере внешнеэкономической деятельности и таможенного дела. В статье анализируются историко-правовые аспекты и перспективные направления развития экономического и таможенного партнерства трех стран в 21 веке в условиях глобализации и международной интеграции
A Visual Pathway Links Brain Structures Active during Magnetic Compass Orientation in Migratory Birds
The magnetic compass of migratory birds has been suggested to be light-dependent. Retinal cryptochrome-expressing neurons and a forebrain region, “Cluster N”, show high neuronal activity when night-migratory songbirds perform magnetic compass orientation. By combining neuronal tracing with behavioral experiments leading to sensory-driven gene expression of the neuronal activity marker ZENK during magnetic compass orientation, we demonstrate a functional neuronal connection between the retinal neurons and Cluster N via the visual thalamus. Thus, the two areas of the central nervous system being most active during magnetic compass orientation are part of an ascending visual processing stream, the thalamofugal pathway. Furthermore, Cluster N seems to be a specialized part of the visual wulst. These findings strongly support the hypothesis that migratory birds use their visual system to perceive the reference compass direction of the geomagnetic field and that migratory birds “see” the reference compass direction provided by the geomagnetic field
