The article examines the conditions of production and recognition of scientific cinema in Brazil by comparing three distinct moments and contexts: the first moment takes place in the nineteenth century, and it is related to the contribution of a Brazilian astronomer otherwise little known to Brazilian film scholars, the second addresses Benedito Junqueira Duarte’s voluminous mid-twentieth-century filmography, and the third moment documents recent scientific film experiences within ultra high resolution movies transmitted over photonic networks. Future trajectories for aesthetic concerns and practical issues such as the archiving of ultra high definition cinema are usefully informed by these histories of scientific cinema, even as a current generation of multidisciplinary teams including scientists, filmmakers, computer scientists, and network engineers reinvent, rediscover, and necessarily expand the scientific cinema toward concerns of real time collaboration and teaching.

ABSTRACT Objectives: to develop and validate an obstetric surgical safety checklist for intraoperative care. Methods: this is a methodological study with two phases: integrative review in databases, using selection criteria and descriptors to synthesize the evidence and develop the checklist; checklist content validation, with 37 judges, who answered a Likert-type questionnaire. For analysis, a >85% content validation index was applied. Results: the checklist’s first moment reached a 96.1 content validation index; the second moment, 95.5; the third moment, 98.9. Thus, the validation index of all verifying sections present in the three surgical moments was 97.1. Cronbach’s Alpha value was 95.57%. Conclusions: the checklist items were validated by judges, with improvement of some items and insertion of others.

This article considers issues of authorship and textual development over the generations, focusing on the contributions of the erudite scholar/lama Dudjom Jigdral Yeshe Dorje (bdud ’joms ’jigs bral ye shes rdo rje, 1904–1987, hereafter, Dudjom Rinpoche), to the revelations of Bhutan’s national saint, Pema Lingpa (padma gling pa, 1450–1521), on the tantric deity Vajrak?laya. Dudjom Rinpoche compiled a number of ritual practice texts for this revelation cycle, also writing commentarial instructions on them. Here, two of his compilations are examined in detail, considering how they relate to the original revelation, what they add, and what they neglect, reflecting on what they might tell us about Tibetan approaches to continuing textual production in revelatory traditions. Much of Dudjom Rinpoche’s ‘Ultra Secret Razor Lifeforce’ Framework text for the Major Practice session (sgrub khog) reproduces virtually unchanged his earlier Framework text for the Dudjom tradition ‘Meteoric Iron Razor’, which itself draws on Guru Chöwang’s (chos dbang, 1212–1270) ‘Ultra Secret Razor’, as presented by Terdak Lingpa (gter bdag gling pa, 1646–1714), the founder of Mindroling Monastery in central Tibet. On the other hand, Dudjom Rinpoche’s main Ritual Manual (las byang) for Pema Lingpa’s cycle is more clearly rooted in the Pema Lingpa cycle, but there has been considerable re-working of the phrasing and even of some key visualisations. Some of the significant modifications were already present in an earlier Ritual Manual of the third Sungtrul (gsung sprul) or Pema Lingpa reincarnation, Tsultrim Dorje (tshul khrims rdo rje, 1598–1669), and Dudjom Rinpoche acknowledges this source. In assessing Dudjom Rinpoche’s two texts, various aspects of the productive process are highlighted, such as: the ‘blessings’ of a current generation high status lama connected with the tradition; the needs of the ritual community for familiar textual structures and liturgies; beautiful metrical verses for chanting; the integration of materials from the broader tantric heritage, but also the preservation of some highly individual elements of the revelation.

An output signal from a multi-section wireless relay communication system is equal to the product of the signal envelopes from individual sections. In this paper, a three-sections relay system is considered in the presence of Nakagami-m fading at each section. First, random variable (RV) is formed as the product of three Nakagami-m RVs. For such product, the moments are determined in the closed forms. The first moment is the mean of the signal; the second moment is the average power of the signal, and the third moment is skewness. Then, the Amount of Fading (AoF) is calculated. AoF is a measure of the severity effect of fading in a particular channel model. Besides, all system performance are shown graphically and the parameters influence has been analyzed and discussed.

We engage with David Andolfatto (2018) on the theme. The two approaches are alleged to have converged in regarding banks as creators of money in the process of initiating lending. We synthesise insights from different factions of the French camp of political economy to make the case that heterodoxy is richer than this claim. Money as an asset-liability is the wage fund in the “first moment” of the monetary circuit. The accumulation of capital is the “second moment” in the sequence, recorded in a separate account at the bank or supported by a financial institution. The “third moment” is the closing of the accounts of demands and supplies generated by the first two moments. Régulation Theory is a related internally-consistent conceptual structure which tracks modes of production as they evolve in history. We dwell on the constructive aspects of the programme as scholars stitch together elements of the present and develop an apparatus to grapple with the emerging new regime of production and distribution. The private sector and state are joined and the bank-central bank is a continuum. Finally, the class structure in the heterodox approach goes deeper than agent heterogeneity.

AbstractClosed expressions for the first, second, and (in some cases) the third moment of atomic transition arrays now exist. Recently a method has been developed for getting to very high moments (up to the 12th and beyond) in cases where a “collective” state-vector (i.e. a state-vector containing the entire electric dipole strength) can be created from each eigenstate in the parent configuration. Both of these approaches give exact results. Herein we describe astatistical(or Monte Carlo) approach which requires onlyonerepresentative state-vector |RV> for the entire parent manifold to get estimates of transition moments of high order. The representation is achieved through the random amplitudes associated with each basis vector making up |RV>. This also gives rise to the dispersion characterizing the method, which has been applied to a system (in the M shell) with≈250,000 lines where we have calculated up to the 5th moment. It turns out that the dispersion in the moments decreases with the size of the manifold, making its application to very big systems statistically advantageous. A discussion of the method and these dispersion characteristics will be presented.

The present paper is focused on the extraction of gold from high-grade e-waste, i.e., spent electronic connectors and plates, by leaching and electrowinning. These connectors are usually made up of an alloy covered by a layer of gold; sometimes, in some of them, a plastic part is also present. The applied leaching system consisted of an acid solution of diluted sulfuric acid (0.2 mol/L) with thiourea (20 g/L) as a reagent and ferric sulfate (21.8 g/L) as an oxidant. This system was applied on three different high-grade e-waste, namely: (1) Connectors with the partial gold-plated surface (Au concentration—1139 mg/kg); (2) different types of connectors with some of which with completely gold-plated surface (Au concentration—590 mg/kg); and (3) connectors and plates with the completely gold-plated surface (Au concentration—7900 mg/kg). Gold dissolution yields of 52, 94, and 49% were achieved from the first, second, and third samples, respectively. About 95% of Au recovery was achieved after 1.5 h of electrowinning at a current efficiency of only 4.06% and current consumption of 3.02 kWh/kg of Au from the leach solution of the third sample.

First Moment

Although Belgian diplomats analysed the nazi-regime from the very first moment as intrinsically crimina!, inhuman, dictatorial and revenge seeking, they showed the nazis in 1934-1935 that dialogue was possible.  The nazi-diplomacy, with secrecy as a keystone, permitted some of the most important Belgian politicians and businessmen to meet the.nazi-leaders without being disapproved by public opinion or even parliament.  This resulted in a «practical» way to improve political and above all economical relations between Belgium and nazi-Germany. It can be seen as a Belgian answer to the inability of France and Great Britain to force the Third Reich to respect the international security treaties which were to guarantee the sovereignty of Belgium.

For a Banach space B let P denote the canonical projection of the third dual space of B onto the embedding of the first dual into the third. It is shown that if B = l1 then ‖I-P‖ = 2.This fact shows to be mistaken a current belief in a statement which is equivalent to the statement that for all Banach spaces B the operator I – P is of norm one.
