Learning as movements in interspace

My research issues (in rearch project for PhD-degree, named Drama in School) concern how learning takes place in drama education in compulsory school. One part is to explore and problematize approaches to learning (in and through drama). In this paper will the concept learning be discussed by using a thought derived from Deleuze and Guattari’s nomad philosophy. They describe learning as a movement in the interspace. Focus is on process and inquiry, not on achievement of predetermined skills and competences.

Performances of single and two-stage pulse tube cryocoolers under different vacuum levels with and without thermal radiation shields

Single and two-stage Pulse Tube Cryocoolers (PTC) have been designed, fabricated and experimentally studied. The single stage PTC reaches a no-load temperature of similar to 29 K at its cold end, the two-stage PTC reaches similar to 2.9 K in its second stage cold end and similar to 60 K in its first stage cold end. The two-stage Pulse Tube Cryocooler provides a cooling power of similar to 250 mW at 4.2 K. The single stage system uses stainless steel meshes along with Pb granules as its regenerator materials, while the two-stage PTC uses combinations of Pb along with Er3Ni/HoCu2 as the second stage regenerator materials. Normally, the above systems are insulated by thermal radiation shields and mounted inside a vacuum chamber which is maintained at high vacuum. To evaluate the performance of these systems in the possible conditions of loss of vacuum with and without radiation shields, experimental studies have been performed. The heat-in-leak under such severe conditions has been estimated from the heat load characteristics of the respective stages. The experimental results are analyzed to obtain surface emissivities and effective thermal conductivities as a function of interspace pressure.

陕北何家集区延长组长4＋5－长6储层特征研究

Abstract： Hejiaji area lies on eastern part of Shanbei Slope in Ordos Basin and the primary oil-bearing bed is Chang 4＋5 and Chang 6 of Yanchang Formation. It is indicated that the sedimentary facies and reservoir characteristics restricted the hydrocarbon accumulation regularity by the geological information. Therefore, Applied with outcrop observation，core description, geophysical logging interpretation, thin section determination, Scanning Electron Microscope, reservoir lithology and physical property analysis and other analytic machinery, the sedimentary facies ,micro-characteristic and master control factors on hydrocarbon reservoir of Yanchang Formation in Hejiaji area are studied deeply by means of sedimentology，reservoir geology and petroleum geology and provide a reliably reference for later prospect . Delta facies are identified in Hejiaji area and of which distributary channels in delta plain microfacies controlled the distribution of sand bodies and accumulation of oil and gas.The distribution of sand bodies distributed from northeast to southwest are dominated by sedimentary facies . It was shown that the sandstones are medium to granule arkose，which the mud matrix is r and including，calcite，the content of matrix is lower and that mostly are cements which are mainly quartz and feldspar overgrowths and chlorite films, in the second place are hydromica and ferrocalcite. All the sandstones have entered a period of late diagenetic stage in which the dominant diagenesis types in the area are compaction, cementation and dissolution. Remnant intergranular porosity and feldspar dissolved pore are main pore types which are megalospore and medium pore. Medium-fine throat, fine throat and micro-fine throat are the mainly throat type. Pore texture can be classified as megalospore and fine throat type, medium-pore and micro-fine throat type mainly, and they are main accumulate interspace in research region. The reservoir of Yanchang Formation in Hejiaji area is low- pore and low- permeability in the mass which have strong heterogeneity in bed, interbedded and plane. Studying the parameter of pore and permeability comprehensively and consulting prevenient study results of evaluation of reservoir, the reservoir is classifiedⅡ，Ⅲ and Ⅳ three types in which the Ⅱand Ⅲ can be divided into Ⅱa and Ⅱb, Ⅲa and Ⅲb respectively. Ⅱb and Ⅲa are the main reservoir type in Hejiaji area which are about 72.73％and 80％percent of whole reservoir and effective reservoir respectively.

Le dialogue des juges entre la Cour européenne des droits de l’homme et la Cour interaméricaine des droits de l’homme

Cette étude a pour but de présenter le dialogue entre les juges de la Cour européenne des droits de l’homme (CEDH) et de la Cour interaméricaine des droits de l’homme (CIADH), deux Cours régionales supranationales, visant toutes deux à garantir le respect des droits fondamentaux. Le dialogue est étudié à travers l’analyse du contentieux portant sur l’intégrité de la personne humaine et sur la protection des droits économiques et sociaux. Ce sujet se rattache au contexte de mondialisation qui vient transformer les relations de pouvoir et révèle l’émancipation des juges dans la régulation transgouvernementale. Le présent mémoire conclut que le dialogue vise à établir une cohérence entre les systèmes afin de faire prévaloir une vision commune des droits de l’homme à travers la constitution d’un espace euro-américain, tel un réseau d’échange informel. Néanmoins, le dialogue est limité par certains facteurs contextuels liés aux réalités contrastées des deux systèmes régionaux ainsi que par la volonté des acteurs étatiques.

Compressive deformation and damage of Mg-based metallic glass interpenetrating phase composite containing 30-70 vol% titanium

Mg-based metallic glass interpenetrating phase composites (IPCs) containing 30-70 vol% titanium was fabricated in this study. The effects of reinforced phase volume fraction and interspace on the mechanical properties were investigated systematically. With increasing the volume fraction of titanium, the fracture strength and strain increased up to 1860 MPa and 44%, respectively. The results showed that the critical volume fraction (around 40%) of Ti metal should be required for significantly improving plasticity of IPC. Decreasing the interspace of the titanium phase could lead to enhancement of yield and fracture strength. The deformation behavior and strengthening mechanisms were discussed in detail.

The idea of Rome in Fascist art and architecture : the decorative program of the Palazzo dei Congressi in EUR, Rome

This paper engages with the notion of interspace by examining an understudied and unpublished cycle of mosaics and frescoes destined for the main hall of the Palazzo dei Congressi in Rome’s south-western suburb of EUR, a major building project by Roman architect Adalberto Libera. It first provides a socio-historical and aesthetic background to the building of EUR as Rome’s international exposition of 1942, which aimed to celebrate the achievements of Italian (and fascist) civilisation. It then focuses on the concept of Romanità (or Roman-ness) as a mythical and idealised past that was engaged on a number of levels as a teleological foundation for the advent (and eternity) of fascist rule. This past was adopted, interpreted and made manifest at the urban scale in the master plan of EUR, at the architectural scale in the buildings and at the interior scale in the decorative programs incorporated in each. It argues that the Palazzo dei Congressi allows us to gain further insight into the notion of interspace as it exemplifies this on a number of physical, symbolic and temporal levels. Physically, in the urban space, architectural form and interiors; symbolically, in the content and compositional layout of the mosaics; and temporally, in the use of historical elision and conflation between mythical pasts and idealised present.

O lugar no espaço: de Martin Heidegger para Eduardo Chillida

In preparing the book Art and Space - originally titled Die Kunst und der Raum (1969) - together with the work of Eduardo Chillida, and devote the text written to the sculptor, Heidegger seems to see in the works of Chillida some of his key themes rescued and reunited. This fusion of content and thought was revealed in his dialogue, at another moment, with the poetry of Friedrich Hölderlin. This dissertation aims to present some of the fundamental concepts in Heidegger's work, especially space, place and art; as well as explain the dialogue between these concepts and the works and thoughts of the sculptor Eduardo Chillida. Amongst the main points of this convergence of thought between the philosopher and the sculptor, we can find: the definition of art; the relationship of world and earth; the thinking about the place of art nowadays; and the meanings of interspace, to incorporate and make the space positive

Efeitos da administração subaracnóidea de grandes volumes de lidocaína a 2% e ropivacaína a 1% sobre a medula espinhal e as meninges: estudo experimental em cães

JUSTIFICATIVA E OBJETIVOS: A injeção de grandes volumes de anestésico local no espaço subaracnóideo, após punção dural acidental, é complicação da anestesia peridural. O objetivo desta pesquisa foi investigar as possíveis alterações clínicas e histológicas desencadeadas por grandes volumes de lidocaína a 2% e ropivacaína a 1%, simulando injeção subaracnóidea acidental, em cães. MÉTODO: Vinte e um cães foram distribuídos aleatoriamente em 3 grupos, que receberam por via subaracnóidea: G1 - cloreto de sódio a 0,9%; G2 - lidocaína a 2% e G3 - ropivacaína a 1%. A punção subaracnóidea foi realizada no espaço intervertebral L6-L7. O volume de anestésico local administrado foi de 1 ml para cada 10 cm de distância entre a protuberância occipital e o espaço lombossacral (5 - 6,6 ml). Após 72 horas de observação clínica os animais foram sacrificados e foi removida a porção lombossacral da medula para exame histológico, por microscopia óptica. RESULTADOS: Nenhum animal do G1 apresentou alterações clínicas ou histológicas da medula espinhal. Foram observados dois casos de necrose do tecido nervoso em G2, porém mudanças clínicas, em somente um desses cães e em outros dois animais que não apresentaram alterações histológicas. Foi encontrada necrose focal do tecido nervoso medular em um animal de G3. Todos os animais de G3 permaneceram clinicamente normais. CONCLUSÕES: Conclui-se que grandes volumes de lidocaína a 2% determinaram alterações clínicas e histológicas mais intensas que os de ropivacaína a 1%.

O cultivo de yacon no Brasil

O yacon (Polymnia sonchifolia Poep. Endl.) é uma espécie da família Asteraceae que apresenta um complexo sistema subterrâneo. Suas raízes tuberosas e rizóforos contêm grandes quantidades de frutose e glicose livres, além de fruto-oligossacarídeos do tipo inulina como carboidrato de reserva. Vem despertando interesse principalmente por suas propriedades medicinais, sendo utilizado como auxiliar no tratamento contra diabetes e colesterol. Foi introduzido no Brasil por volta de 1989, porém somente em 1994 iniciaram-se os primeiros cultivos comerciais. Atualmente é cultivado na região de Capão Bonito (SP), a partir de rizóforos pesando de 60 a 80 g. Estes são plantados em canteiros de 0,30 - 0,40 m de altura por 1,0 m de base, em um espaçamento de 1,00 x 0,90 m. O pH do solo é ajustado para 6,0 e a fertilização básica é realizada com NPK + Zn, de acordo com análise e a recomendação utilizada para batata doce. Posteriormente são aplicados 40 kg.ha-1 de N em duas parcelas. A irrigação é feita por aspersão e a colheita realizada entre os 8 e 10 meses após o plantio, obtendo-se um rendimento médio de 80 t.ha-1 de raízes e 1 t.ha-1 de folhas desidratadas. Tanto as raízes como as folhas podem ser consumidas frescas ou desidratadas em estufas com ventilação forçada, à temperatura máxima de 50°C, para se evitar a degradação dos carboidratos de reserva e das substâncias do metabolismo secundário.

Cauda equina syndrome after spinal tetracaine: Electromyographic evaluation-20 years follow-up

CAUDA equina syndrome (CES) has long been recognized as a rare complication of spinal anesthesia.(1) CES has been described after administration of spinal anesthetics with lidocaine(2) and bupivacaine.(3) In 1991,(4) CES was reported after continuous spinal anesthesia with 1% tetracaine. In 1980, at our university hospital, six adult female patients underwent perineal gynecologic surgery using a spinal anesthetic of 2 ml tetracaine, 1.2%, in 10% glucose. The concentration of the injected tetracaine was unknown by the anesthetists. In all cases, lumbar puncture was performed at the L3-L4 interspace with a disposable spinal needle while the patients were in the sitting position. CES was first diagnosed 72 h or later postoperatively; previous diagnosis was not possible because patients had an indwelling urethral catheter. The diagnosis of CES was confirmed in all patients. During the past year, after institutional approval and informed consent, clinical, magnetic resonance imaging, electromyographic examinations, and conduction studies were performed in three of the above patients. Examinations were not possible on the other three patients because one had recently died, another could not be located, and the third refused to participate. T1 and T2 magnetic resonance image readings were obtained with Gadolinium contrast from a 0.5 Tesla General Electric apparatus (General Electric, Tokyo, Japan). Bilateral sensory and motor conduction studies of the sciatic nerve branches were obtained using a two-channel Nihon-Kohden Neuropack 2 (Nihom-Kohden Corporation, Tokyo, Japan). Electromyography was performed in accordance with conventional techniques.(5,6)

Efeitos de diferentes doses de tenoxicam sobre a medula espinhal e as meninges. Estudo experimental em caes

Background and Objectives. The analgesic actions of nonsteroidal anti-inflammatory drugs (NSAID) result from the inhibition of the peripheral synthesis of prostaglandins. In spite of the emphasis on the peripheral action, several studies have shown the potential central action of such drugs. In rats, NSAID doses insufficient to block pain when systemically administered were effective when intrathecally injected. This effect could be mediated by interaction with descending serotoninergic ways together with neurotransmission modulation of glycine or N-methyl-D-aspartate receptors. Our goal was to study the effect of different tenoxican doses in the histology of dogs spinal cord and meninges. Methods. Thirty two dogs (7 to 17 kg) were randomly distributed in four groups: G1 - Control with distilled water (DW); G2 - 2 mg tenoxican diluted in DW; G3 - 4 mg tenoxican diluted in DW; G4 - 10 mg tenoxican diluted in DW in a constant volume of 1 ml. Anesthesia was induced with etomidate and fentanyl and dural puncture was performed with a 25G spinal needle in interspace L6-7. Animals were observed for 72 hours and subsequently euthanized by electrocution. Lumbar and sacral spinal cord segments were removed for further histologic examination. Results. All animals were clinically normal during the observation period and there has been no histologic alteration of the nervous system and meninges. Conclusions. In our experimental model intrathecal tenoxican doses up to 10 mg have not triggered nervous tissue or meningeal injuries in dogs.

The effects of thoracic epidurally administered drugs on urethral sphincter function in women: a pooled analysis

OBJECTIVES Thoracic epidural analgesia (TEA) has been shown to inhibit detrusor activity in patients undergoing open renal surgery, resulting in clinically relevant post-void residuals. However, the impact of different epidural drug mixtures on urethral sphincter function is not completely elucidated. DESIGN Pooled analysis of an open observational study and a double-blind randomized trial. SETTING Single tertiary centre. SUBJECTS Twenty-eight women without lower urinary tract symptoms and post-void residual <100 mL, who underwent open renal surgery with TEA. METHODS Pooling results in three groups with different epidural regimens (7 with bupivacaine 0.125%, 8 with bupivacaine 0.125% and fentanyl 2 μg/mL, and 13 with bupivacaine 0.1% plus fentanyl 2 μg/mL and epinephrine 2 μg/mL). All women underwent urethral pressure measurements before TEA and during TEA 2-3 days postoperatively. All patients received a TEA placed at the insertion site interspace T 8-9. RESULTS Maximum urethral closure pressure at rest decreased significantly during TEA with bupivacaine alone (median 70 cm H2 O [interquartile range 66-76] to 43 [43-65], P = 0.031) and with bupivacaine/fentanyl/epinephrine (75 cm H2 O [68-78] to 56 [52-75], P = 0.028), whereas with bupivacaine/fentanyl, no significant change could be detected (74 [51-88] vs 67 [46-70], P = 0.156). In all groups, functional profile length at rest was not influenced during TEA. CONCLUSION TEA with bupivacaine and the addition of fentanyl and epinephrine appears to decrease maximum urethral closure pressure at rest in women. The addition of fentanyl alone to bupivacaine may reduce this effect. Thus, the TEA effect on urethral sphincter function seems to depend on the drug mixture administered.

Quantification of Mitral Regurgitation with Multiple Jets: In Vitro Comparison of Two-dimensional PISA techniques

Purpose: Traditionally, the proximal isovelocity surface area (PISA) is based on the assumption of a single hemisphere (hemispheric PISA), but this technique has not been validated for the quantification of mitral regurgitation (MR) with multiple jets. Methods: The left heart simulator was actuated by a pulsatile pump at various stroke amplitudes. The regurgitant volume (Rvol) passing through the mitral valve phantoms with single and double regurgitant orifices of varying size and interspace was quantified by a flowmeter as reference technique. Color Doppler 3-D full-volumes were obtained, and Rvol were derived from 2-D PISA surfaces on the basis of hemispheric and hemicylindric assumption with one base (partial hemicylindric PISA) or 2 bases (total hemicylindric PISA). Results: 72 regurgitant volumes (Rvol range: 8 to 76 ml/beat) were obtained. Hemispheric PISA Rvol correlated well with reference Rvol by one orifice (R²=0.97; bias -2.7±3.2ml), but less by ≥ one orifice (R²=0.89). When a fusion of two PISAs occured, addition of two hemispheric PISA overestimated Rvol (bias 9.1±12.2ml, fig.1), and single hemispheric PISA underestimated Rvol (bias -12.4±4.9ml). If an integrated approach was used (hemispheric in single orifice, total hemicylindric in two non-fused PISAs and partial hemicylindric in two fused PISAs), the correlation was R²=0.95, bias -1.6±5.6ml (fig.2). In the ROC analysis, the cutoff to detect ≥ moderate-to-severe Rvol (≥45ml) was 42ml (AUC 0.99, sens. 100%, spec. 93%). Conclusions: In MR with two regurgitant jets, the 2-D hemicylindric assumption of the PISA offers a better quantification of Rvol than the hemispheric assumption. Quantification of MR using 2-D PISA requires an integrated approach that considers number of regurgitant orifices and fusion of the PISAs.
