Naturaleza y hormigón. Espai Verd

<p>Espai Verd, obra del estudio de arquitectura CSPT bajo la dirección de Antonio Cortés Ferrando, es una singular edificación de arquitectura modular en el espacio, situada en el barrio de Benimaclet, Valencia. Data de principios de la década de los 80, y fue realizada mediante el sistema de cooperativa de propietarios. El concepto principal, del que parte el proyecto, es el de materializar viviendas con jardín individual, dispuestas en un edificio plurifamiliar en altura. Consecuentemente, la principal característica de la obra es la integración de la naturaleza como parte intrínseca de la edificación y el necesario desarrollo de un sistema constructivo capaz de albergar la vegetación, donde destaca el empleo de hormigón visto, tanto in situ como prefabricado. El diseño fue influenciado por las tendencias arquitectónicas propias de la época, el brutalismo y las megaestructuras, además de contar con numerosos referentes particulares como obras de Moshe Safdie, Ricardo Bofill y José Antonio Coderch, entre otros. El texto expone algunas de las estrategias y decisiones realizadas en este proyecto que condicionan el aspecto formal del edificio y, a su vez, ponen de manifiesto la estrecha relación entre naturaleza y hormigón para Espai Verd<em>.</em></p>

Central nervous system vascular diseases in ophthalmology clinic

Central nervous system vascular disease can be combined with a variety of ocular signs, such as orbital pain, flash, visual field defects, vision loss, eye muscle paralysis. Therefore, some patients were first diagnosed in ophthalmology, including aneurysm rupture, arterial dissection, cerebral apoplexy and other critical nervous system diseases that need rapid treatment. If the doctors didn't know enough, the diagnosis and treatment might be delayed. Most of the vascular diseases of the central nervous system related to ophthalmology have clinical manifestations that cannot be explained by ophthalmology. In the face of chronic conjunctivitis, unexplained visual field defect or cranial nerve paralysis with local ineffective treatment, it is necessary to broaden the thinking of differential diagnosis. To understand the characteristics of vascular diseases of the central nervous system that are prone to ocular manifestations can provide references for the clinical diagnosis and treatment of ophthalmology.

Les représentations de la Révolution de 1917 dans le discours officiel en Russie contemporaine : le rôle de la doxa dans les stratégies discursives.


 
 
 Depuis la perestroïka, les représentations de la Révolution russe de 1917 ont subi des changements profonds, renversant le mythe révolutionnaire soviétique. Les dirigeants politiques russes des années 2000 font un usage sélectif de ces représentations transformées dans leurs stratégies discursives. Cet article interroge la façon dont la révolution est traitée dans l’espace communicatif du Kremlin, après la rupture avec la mythologie soviétique et au moment de la recherche d’une certaine continuité avec l’époque soviétique. En effet, le concept de révolution, avec des références aux événements et figures du moment révolutionnaire, est réactualisé dans le discours politique russe contemporain dès avant les « révolutions de couleur » dans l’espace postsoviétique. Ces bouleversements réduisant la distance entre l’usage du soft power et du hard power inquiètent le pouvoir russe et l’incitent à chercher des instruments d’autolégitimation dans la mémoire historique, en particulier dans celle des révolutions de 1917. Les représentations du moment révolutionnaire dans le discours du pouvoir russe contemporain s’appuient sur la doxa héritée de l’époque de la perestroïka. Cependant, certains éléments de cette doxa sont utilisés pour défendre le paradigme évolutionniste qui constitue le fondement de la légitimité du pouvoir. Cette étude montre ainsi comment les dirigeants russes contemporains parviennent à inscrire dans leurs stratégies d’autoreprésentation et d’argumentation les divers éléments constitutifs des nouvelles représentations de la révolution. L’article interroge la place des représentations de la révolution dans les procédés rhétoriques et discursifs de légitimation de Soi et de délégitimation de l’Autre.
 
 

Performatividade, assujeitamento e silenciamento do “eu gay”: reflexões entre docência e diversidade sexual

A discussao e possibilidade de inclusao da tematica diversidade sexual na formacao educacional irrompem na possibilidade de se pensar outras formas de desejos e intencionalidades relacionados a vivencia da sexualidade, adquiridas enquanto uma (trans)formacao cultural e social voltada ao construto de referenciais e metodologias proprias ao entendimento das diferencas de relacoes afetivos-sexuais no espaco formativo educacional. O objetivo deste ensaio cientifico se ambasa na necessidade de analisar de que forma a docencia e diversidade sexual se articulam para construir e significar performances de genero, e de como essa construcao se aproxima ou influencia o fazer educativo no espaco da escola e da universidade. As reflexoes que ressalto neste artigo apontam que a escola em sua funcao de formacao para cidadania, emancipacao, direitos e deveres ainda nao contornou o retrocesso do preconceito estrutural. Por isso, tanto a educacao basica como superior descumprem em certa medida a transformacao da realidade dos sujeitos que nelas se inserem.

Design and experiment evaluation of furrow compaction device with opener for maize

The double-disc opener of maize precision seeder is an important component which affects sowing quality. After the double-disc opening operation, there will be many unfavorable phenomena such as a W-shaped bottom with pointed ridge, returning soil to furrow, loose and rough furrow sidewall, and large soil blocks in the furrow bottom. These phenomena often cause the problems of poor sowing depth consistency and seed spacing uniformity. In order to solve the above problems, the furrow compaction device with opener was designed to compact and reshape the original seed furrow, eventually forming a smooth and flat V-shaped seed furrow. Through theoretical calculations and kinematic analysis, the main structural parameters of the device were limited to a small range: the spring stiffness coefficient k=0.96-4.19 N/mm and the angle of the furrow compaction wheel φ=30°-60°. In the soil-bin experiment, the rotary combination design was adopted to study the effects of the parameters of the furrow compaction device with opener on the seeds location variation. The regression model of two factors with respect to each indicator was established in the Design-Expert software, revealing the effects of two factors on the indicators. Finally, the optimal structural parameters obtained were: the spring stiffness coefficient k=4.0 N/mm, and the angle of furrow compaction wheel φ=42.4°. The field test was carried out to verify the effect of the furrow compaction device with opener on the performance of precision seeder. The results showed that the average values of the sowing depth variable coefficient, the lateral deviation and the seed spacing variable coefficient respectively were 5.77%, 5.1 mm and 9.54% in the treatment of the furrow compaction device with opener. All indicators were superior to the traditional double-disc opener. This research can provide references for the design of furrow opening device and maize precision seeder.

Design and experiment of a high-clearance self-propelled sprayer chassis

A large high-clearance self-propelled sprayer chassis was designed according to the requirements of the sprayer’s driving operation and the overall goal. The structural characteristics and working principle of the chassis drive system, suspension system, track adjustment system, and frame were analyzed. A finite element analysis of the frame was carried out under four extreme conditions: full load bending, full load torsion, full load emergency braking and full load emergency turning. Under these four conditions, the maximum stress values of the frame were 149.45 MPa, 219 MPa, 151.44 MPa, and 123.27 MPa respectively, and the maximum strain values were 1.12 mm, 2.22 mm, 0.95 mm, and 1.16 mm respectively. A theoretical analysis of the stability, steering ability, and obstacle navigation of the sprayer chassis was conducted. The results showed that the upper angle θlim, lower angle θ׳lim and lateral limit tumbling angle φlim of the sprayer chassis were 50.1°, 30.0° and 35.3° respectively. The minimum turning radius of the chassis was 5816 mm, and the minimum turning width was 4113 mm. The maximum obstacle crossing heights of the front and rear wheels were 466 mm and 457 mm. The theoretical analysis showed that the designed chassis met the field management operations of large plots. A field experiment of the high-clearance self-propelled sprayer chassis at full load was conducted. The experimental results were consistent with the theoretical analysis results. The sprayer chassis not only good handling stability but also good ride comfort. The results of this study provide references for the design of high-clearance self-propelled sprayer chassis.

More infantie a tergo corporis emendari: violencia y disciplina en los ámbitos escolares hispanos (siglos IV-XII)

Este artículo parte de la consideración del ius puniendi aplicado de forma comparativa en las categorías de discípulo/escolar y siervo, tal y como aparece en el Liber Iudiciorum, VI, 5, 8, regulando el castigo para ambas categorías sociales, como forma de disciplina. La consideración de la infancia como una época irracional de la formación del individuo conlleva el derecho al castigo físico con la misma legitimidad que los propietarios a sus esclavos. A partir de esta idea motriz se establecerán las principales referencias sobre la evidencia del castigo físico escolar y doméstico infantil en el mundo hispano altomedieval desde el Peristefanon de Prudencio (s. IV) hasta los recuerdos de Ordoño de Celanova (s. XII).

Formononetin induces apoptosis of PC-3 human prostate cancer cells via regulating long noncoding RNA H19 and the mitochondrial apoptosis pathway

Background: Prostate cancer is a life-threating disease with high incidence and mortality in male. Formononetin, the main active component of some natural products, has been hypothesized as a promising anticancer agent in previous studies. Objectives: We investigated the toxic effects and potential molecular mechanism of formononetin in PC-3 prostate cancer cells to further understand the pharmacological effects of formononetin and provide more references for intensive research. Materials and Methods: PC-3 cells were incubated with different doses of formononetin for 24 h or 48 h. After that, cell viability was measured by Cell Counting Kit-8, and apoptosis was analyzed by Hoechst 33258 stains. The expression levels of tumor-related factors such as long noncoding RNA (LncRNA) H19, Bax, and Bcl-2 were determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blot methods. Subsequently, PC-3 cells were infected with a lentiviral vector to overexpress or knock down H19, and then, the expression of insulin-like growth factor-1 receptor (IGF-1R) mRNA was measured by RT-qPCR. Results: Formononetin significantly inhibited the viability of PC-3 cells and promoted apoptosis in a time-dose-dependent manner. We observed that the expressions of lncRNA H19 and Bcl-2 were significantly downregulated compared with the untreated group, while an opposite pattern was observed for Bax. According to the results of gene interaction experiments, IGF-1R may be a downstream target of H19 in PC-3 cells. Conclusion: Our results present evidence that formononetin induced apoptosis of PC-3 cells by regulating lncRNA H19 and the mitochondrial apoptosis pathway. Furthermore, we put forward the hypothesis that formononetin has an interference effect on the H19/IGF-1R pathway, which remains to be further confirmed.

Progress in localization of pulmonary nodules

With the development of CT and the popularization of health examination, the detection rate of small pulmonary nodules has been improved. Some small pulmonary nodules could be malignant nodules. Surgical resection is the preferred treatment. Therefore, it is an important task for thoracic surgeons to accurately locate pulmonary nodules during surgery and remove nodules accurately on the premise of maximum protection of lung function. At present, the core of preoperative auxiliary localization of pulmonary nodules is the implantation of markers. The commonly used clinical localization methods include hook wire localization, microcoil localization, methylene blue puncture injection localization and biological glue localization. In this paper, the development status, application scope, advantages and disadvantages of existing localization methods are briefly reviewed, which can provide references for clinical application and follow-up research.
