Le phénomène Proto-Élamite et la construction archéologique de la révolution proto-urbaine en Iran du Sud-Ouest
Authors: Naccaro Hugo 
Published: December 2017

Le tournant des IVe et IIIe millénaires avant J.-C. en Iran du sud-ouest est marqué par une révolution majeure : celle de l’apparition de l’État et de l’écriture. Elle est plus précisément la période d’aboutissement de la révolution proto-urbaine, résultat d’un long processus, commencé dès le Ve millénaire.Le terme « proto-élamite » a été, dans un premier temps, une dénomination issue de la philologie. Il permettait de définir une écriture différente de la tradition sud mésopotamienne qui apparaît à la toute fin du IVe millénaire en Iran du sud-ouest. Cette dénomination a par la suite acquis une connotation archéologique (période, culture et « civilisation »). À partir du modèle d’expansion proto-urbaine sud mésopotamien dit d’ « Uruk » (IVe millénaire), le terme proto-élamite a également permis de désigner un phénomène de même nature en Iran entre 3300/3100 et 2800/2600 av. J.-C.. Ces deux phénomènes (Uruk et proto-élamite) sont nettement différenciés : chronologie, culture matérielle, écriture, originalité artistique. Cependant ils sont indubitablement liés. De nouvelles découvertes et recherches poussent aujourd’hui différentes écoles à remettre en cause la construction archéologique du « phénomène Proto-Élamite ». En effet, l’emploi de cette terminologie a été utilisé afin de désigner une théorique généralisation de la « révolution urbaine » sur une aire géographique très importante et sur un temps relativement court. Cette construction permet d’illustrer les bouleversements radicaux dans l’évolution des sociétés iraniennes à cette période, visibles au travers des restes archéologiques. Cependant elle pose de nombreux problèmes méthodologiques.L’objet de cet article est de tester l’existence du concept du « phénomène proto-élamite » comme « phénomène proto-urbain » en Iran du sud-ouest. Nous aborderons ainsi son historiographie complexe, son analogie fragile avec le phénomène urukéen, en nous appuyant sur nos recherches en stratigraphie urbaine et sur le matériel.
Om die Rubicon oor te steek: Oopmaak van die hekke in die Nederduitsch Hervormde Kerk van Afrika/Crossing the Rubicon: Opening of gates in the Netherdutch Reformed Church in Africa
Authors: Van Eck Ernest 
Published: December 2017

On the occasion of the 500 year commemoration of the Reformation and the centenary celebration of the Faculty of Theology HTS Centenary Volume Two is dedicated to the Netherdutch Reformed Church in Africa (NRCA), the oldest partner of the theological faculty at the University of Pretoria – with grateful recognition to what the NRCA contributed to the practice of critical theology in South Africa over the past 100 years and its support of HTS Theological Studies as title owner for 73 years. HTS Centenary Volume Two takes the form of a compendium of the most important documents that preceded and followed the ‘crossing of the Rubicon’ in the NRCA, as well as the publication of three special collections, namely ‘100 jaar Hervormde Teologie’ (edited by Wim Dreyer), ‘Hervormde teoloë in gesprek’ (edited by Christo van der Merwe), and ‘Kerkhervorming 1517–2017’ (edited by Natie van Wyk).By geleentheid van die 500 jaar herdenking van die Reformasie en die eeufees van die Fakulteit Teologie van die Universiteit van Pretoria, word HTS se Eeufeesbundel Volume Twee opgedra aan die Nederduitsch Hervormde Kerk van Afrika (NHKA), die oudste kerklike vennoot van die teologiese fakulteit aan die Universiteit van Pretoria – uit dankbare erkenning vir wat die NHKA tot die beoefening van kritiese teologie in die afgelope 100 jaar in Suid Afrika bygedra het en vir die ondersteuning van HTS Teologiese Studies as titeleienaar vir 73 jaar. HTS se Eeufeesbundel Volume Twee neem die vorm aan van ’n kompendium van die belangrikste dokumente wat die ‘oorsteek van die Rubicon’ in die NHKA voorafgegaan en opgevolg het, sowel as die publikasie van drie spesiale kolleksies, te wete ‘100 jaar Hervormde Teologie’ (onder redakteurskap van Wim Dreyer), ‘Hervormde teoloë in gesprek’ (onder redakteurskap van Christo van der Merwe), en ‘Kerkhervorming 1517–2017’ (onder redakteurskap van Natie van Wyk).
Die toets van ekstrakte uit <i>Sutherlandia frutescens</i> (Fabaceae) op <i>Mycobacterium smegmatis</i> in die behandeling van tuberkulose
Authors: Mabusa Itumeleng H. , Howard Rachmond , Masoko Peter 
Published: December 2017

Sutherlandia frutescens (L) R. Br. bevat verskeie essensiële bioaktiewe verbindings met farmakologiese aktiwiteit waarvoor daar kliniese bewyse bestaan. Sutherlandia word vir mense met tuberkulose voorgeskryf, maar niemand weet nog watter verbindings in hierdie plant Mycobacterium tuberculosis en die werking daarvan teenwerk nie. Hierdie studie het ten doel om te bepaal of S. frutescens antimikobakteriese verbindings bevat. Bogrondse dele van S. frutescens is gedroog, gemaal en met etanol:metanol [1:1] (vol./vol.) en water onttrek. Die chemiese profiel is bepaal deur hoëverrigting vloeistofchromatografie-massaspektrometrie en dunlaag-chromatografie te gebruik. Die dunlaagchromatografie is in butanol:asynsuur:water (BAW) [21:6:3], chloroform:metanol:water:mieresuur (CMWM1) [60:15:2:1] en CMWM2 [21:9:1:0.3] ontwikkel. Die kwalitatiewe anti-oksidant-aktiwiteit is bepaal deur 2.2 difeniel-2-pikrielhidrasiel (DFPH) te gebruik. Die antimikobakteriese aktiwiteit van die plantekstrakte is bepaal deur mikro-verdunning en bio-outografiese metodes teen Mycobacterium smeagmatis te gebruik. Ons het lae antimikobakteriese aktiwiteit teen M. smegmatis in die bio-outogramme waargeneem. Die profiele van die hoëverrigting vloeistofchromatograpfie-massaspektrometrie het meer verbindings in die etanolekstrakte as in die waterekstrakte aangedui. Die gemiddelde waardes vir minimum inhibeerderkonsentrasie vir al die ekstrakte was 0.61 mg/mL. Die DCM:MeOH (1:1) ekstrak het die laagste minimum inhibeerderkonsentrasie-waarde, naamlik 0.28 mg/mL gehad. Die resultate het getoon dat die plant verder vir moontlike antimikobakteriese agente ondersoek kan word. Lae aktiwiteit is waargeneem, waarskynlik as gevolg van stadig vermeerderende bacilli en nie-vermeerderende organismes. Die studie bied voorlopige wetenskaplike ondersteuning vir die tradisionele medisinale gebruik van hierdie plant.

Version 2 of the IASI NH3 neural network retrieval algorithm: near-real-time and reanalysed datasets
Authors: Van Damme Martin , Whitburn Simon , Clarisse Lieven , Clerbaux Cathy , Hurtmans Daniel , Coheur Pierre-François 
Published: December 2017

Abstract. Recently, Whitburn et al.(2016) presented a neural-network-based algorithm for retrieving atmospheric ammonia (NH3) columns from Infrared Atmospheric Sounding Interferometer (IASI) satellite observations. In the past year, several improvements have been introduced, and the resulting new baseline version, Artificial Neural Network for IASI (ANNI)-NH3-v2.1, is documented here. One of the main changes to the algorithm is that separate neural networks were trained for land and sea observations, resulting in a better training performance for both groups. By reducing and transforming the input parameter space, performance is now also better for observations associated with favourable sounding conditions (i.e. enhanced thermal contrasts). Other changes relate to the introduction of a bias correction over land and sea and the treatment of the satellite zenith angle. In addition to these algorithmic changes, new recommendations for post-filtering the data and for averaging data in time or space are formulated. We also introduce a second dataset (ANNI-NH3-v2.1R-I) which relies on ERA-Interim ECMWF meteorological input data, along with surface temperature retrieved from a dedicated network, rather than the operationally provided Eumetsat IASI Level 2 (L2) data used for the standard near-real-time version. The need for such a dataset emerged after a series of sharp discontinuities were identified in the NH3 time series, which could be traced back to incremental changes in the IASI L2 algorithms for temperature and clouds. The reanalysed dataset is coherent in time and can therefore be used to study trends. Furthermore, both datasets agree reasonably well in the mean on recent data, after the date when the IASI meteorological L2 version 6 became operational (30 September 2014).

D’àngels i dimonis. Anàlisi d’una seqüència del programa iconogràfic de la moralització enciclopèdica de la fin’amors en el Breviari d’Amor de Matfré Ermangaud
Authors: Martines Vicent 
Published: December 2017

Resum: En el present treball parem esment a 3 il·luminacions del Breviari d’Amor de Matfré Ermengaut, a més de ser eloqüents –valga la sinestèsia: imatges que són eloqüents— justament d’aqueixa vocació d’Ermengaud en pro de la cristianització de la fin’amors. Estableixen una mena de seqüència en el concert de diàleg entre història natural, història sagrada i atenció a l’amor, als amadors a fi i efecte que estableix qui és el receptor concret de l’obra, qui el model a seguir (els àngels) i qui a defugir (el dimoni), i quin és l’àmbit d’actuació del «maligne»: la societat cortés, ecosistema de la fin’amor. Paraules clau: Breviari d’amor, enciclopedisme medieval, text i imatge, fin’amor, càtars, moralitazió Abstract: This paper analyzes three illuminations of Matfré Ermengaud´s Breviari d'Amor which represent the author´s attempt to Christianize the concept of fin'amors. In particular, they establish a connection among natural history, sacred history and love and lovers and allow us to study who is the recipient of Ermengaud's work. In addition, they serve us to study the author´s injunctions on the model to be followed (angels), the model to reject (demons), and the sphere of action of «the evil»: courtly society and the ecosystem of fin´amors.

Authors: Granell Sales Francesc 
Published: December 2017

Resum: L’article pretén adverar de quina manera es configurava i s’identificava la figura del rei en Jaume a la Festa de l’Estendard, la commemoració anual de la conquesta cristiana de la ciutat de Mallorca, mitjançant l’anàlisi dels elements visuals i retòrics planificats per al desenvolupament d’aquella. Cal parar atenció, concretament, a dos d’aquests elements: el portaestandard que anava a cavall ben abillat amb armadura i altres objectes i l’eloqüent prèdica –coneguda com el Sermó de la Conquesta– que pronunciava un clergue acreditat per a tal funció. Paraules clau: Jaume I, imatge règia, festes de la Baixa Edat Mitjana, iconografia del poder, Regne de Mallorca Abstract: This paper attempts to discuss the manner in which the image of king James I was customized and established in the Festa de l’Estendard, the annual commemoration ceremony of the christian conquest of the city of Mallorca. We will do so through an analysis of the visual and rhetorical elements planned for the unfolding of the ritual. One should focus particular attention on two of these elements: the standard bearer on horseback well attired in armour and other objects and the speech known as the «Sermó de la Conquesta» delivered by a cleric.

Conversaçiones de Música a finals del segle XVI: el cas de l’acadèmia de Joan de Borja i Castro
Authors: Escrivà-Llorca Ferran 
Published: December 2017

Resum: Aquest article s’insereix dins del conjunt d’investigacions sobre la Cort dels Habsburgs. L’estudi de les acadèmies musicals és poc conegut. A partir d’algunes investigacions sobre acadèmies literàries, l’article focalitzarà en l’acadèmia musical que Joan de Borja i Castro tenia a Madrid. En aquest sentit, si el mecenatge literari cortesà ja és un tema amb múltiples variants, l’aproximació al patrocini d’altres activitats artístiques, com el cas de la música, ho és encara més. En les següents pàgines s’aprofundirà en les diverses facetes erudites de Joan de Borja amb el fil conductor de les acadèmies, com a centre d’intel·lectualitat, de creació i promoció cultural i també personal. Per aquesta acadèmia van passar alguns dels personatges del món musical ibèric més important de l’època com Francisco Guerrero o Tomás Luis de Victoria. Aquest article pretén mostrar la importància d’aquesta acadèmia com un punt neuràlgic del mecenatge musical de les darreres dècades del segle XVI. Paraules clau: Joan de Borja, Borja, acadèmies, Habsburgs, Música, Madrid Abstract: This work is part of the research on The Court of Habsburg in Modern Era. The study of music academies is not quite known. From few works on literary academies, this article will focus on the music academy that of Juan de Borja i Castro hold in Madrid. In this way, if the courtly literary patronage is already an issue with multiple variants, the approach to other artistic activities, such as the music, it is even more. In the following pages, it will delve into the various aspects of erudition of Juan de Borja with the thread of the academies, as a centre of intellectual, creative and cultural promotion and personal. Some of the most important composers of the Iberian World of that time, such as Francisco Guerrero or Tomás Luis de Victoria, were involved in this academy. The article aims to show the relevance of this cenacle as a focal point of the musical patronage in the last decades of the 16th century Spain.

Les revistes bilingües a la Tortosa de la II República
Authors: Gombau Domingo M. Carme 
Published: December 2017

Resum: Enmig d’un panorama periodístic escrit exclusivament en castellà, sorgeix el primer rotatiu escrit íntegrament en català a Tortosa: La Veu de Tortosa. El succeeix La Veu de la Comarca en la voluntat de «desvetllar la consciència catalanista de la comarca tortosina». Tots dos rotatius representen la introducció del regionalisme a les terres de l’Ebre i del catalanisme conservador, en una ciutat on predominaren els partits dinàstics espanyols durant la primera dècada del segle xx. Després del silenci de la dictadura primorriverista, apareix un setmanari homònim del de principis de segle com a plataforma de difusió d’un partit comarcal afí al de la Lliga Regionalista. En contrapartida, la revista Vida Tortosina, primer, i el quinzenari Acció, després, esdevenen els òrgans d’expressió d’Acció Catalana i representen un moderat nacionalisme d’esquerres. Regionalistes i nacionalistes pretenien fer front a la força política majoritària a Tortosa amb l’establiment de la ii República, els republicans marcel·linistes. Paraules clau: terres de l’Ebre, premsa comarcal, catalanisme, actituds lingüístiques Abstract: In the middle of a journalistic circuit written exclusively in Spanish, comes the first newspaper written entirely in Catalan in the city of Tortosa: La Veu de Tortosa. This one is followed by La Veu de la Comarca which has the firm intention of «awake the Catalan consciousness of the district of Tortosa». Both newspapers represent the introduction of regionalism in Terres de l’ Ebre and the Catalan language in a zone dominated throughout the first decade of the twentieth century by Spanish dynastic parties. After the silence of the dictatorship of Primo de Rivera appears a homonymous weekly as a diffusion platform of a district party related to the Lliga Regionalista. In counterpart, the magazine Vida Tortosina first, and the biweekly Acció after, become organs of expression of Acció Catalana and represent a moderate progressive nationalism. Regionalists and nationalists tried to fight the greatest political force in Tortosa with the establishment of the II Republic, the «marcel·linistes» Republicans.

Radioisotopes
Authors: Starovoitova Valeriia 
Published: December 2017

Radioisotopes, also called radionuclides, are unstable atoms that spontaneously decay to more stable elements or other atoms by emission of matter or energy. Radioisotopes are routinely used to determine the ages of materials, for diagnostics and treatment of diseases, for nondestructive evaluation of materials, for the tracking of groundwater or air flow, for food sterilization, and for many other applications.
This article summarizes the nuclear physics properties of radioisotopes and the various radiation particles, including the concepts of half‐life, decay constant, angular momentum, and parity. The modes of nuclear decay and the accompanying radiation are described, as are combined nuclear and atomic processes, and atomic decays and corresponding radiations. Applications for science, medicine, and industry uses of various isotopes are discussed and their production methods are described.
Reactor Technology
Authors: Mann Uzi 
Published: December 2017

Chemical reactor technology is concerned with the selection, design, and operation of a chemical reactor– an equipment unit in a chemical process where chemical transformations (reactions) take place to generate a desirable product at a specified production rate, using a given chemistry.The reactor type (configuration) and its operating conditions are selected to achieve objectives, such as maximizing the profit of the process, and minimizing the generation of pollutants, while satisfying design and operating constraints, including safety, controllability, availability of raw materials, etc. A chemical reactor plays a pivotal role in the operation and economics of the entire process because its performance affects other units in the process such as separation units, utilities, etc.In this article, design considerations of typical reactor configurations and the underlying physical and chemical principles are discussed. Common engineering practices that are applied during chemical reactor development are reviewed. These include experimental reactors, selection of reactor type and configuration, selection of operating conditions, and diagnostics of existing reactors. Examples of industrial reactors are described.
