Validation of the Brazilian versions of two inventories for measuring oral health-related quality of life of edentulous subjects

'Objectives: To analyse the validity of the Brazilian versions of OHIP-EDENT and GOHAI as assessment tools of edentulous subjects' OHRQoL. Background: Inventories for measuring oral health-related quality of life (OHRQoL) are important in clinical studies regarding oral rehabilitation. However, there is a need for comprehensive validation after translation into different cultural settings. Materials and methods: The sample comprised of 100 complete denture wearers (29 men, 71 women, mean age of 65.2 +/- 9.9 years). The associations between each OHRQoL inventory and other variables served as measurements of construct validity. Data analysis comprised the Spearman correlation test as well as multiple regression using the OHRQoL inventories as dependent variables and the other scales as determinants. Results: Both OHRQoL inventories showed good correlation with denture satisfaction, whereas lower correlation coefficients were found among the inventories and the HAD subscales. Denture satisfaction alone explained 48% and 39% of the variance found for the OHIP-EDENT and GOHAI, respectively, as assessed by multiple regression. A smaller effect was found for OHIP-EDENT. Conclusion: Both OHIP-EDENT and GOHAI showed good construct validity for measurement of OHRQoL of edentulous subjects.

Differential expression of HIF-1α in CD44+CD24-/low breast ductal carcinomas

Abstract Background Cancer stem cell (CSC) hypothesis postulates that tumors are maintained by a self-renewing CSC population that is also capable of differentiating into non-self-renewing cell populations that constitute the bulk of tumor. Stem cells renewal and differentiation can be directly influenced by the oxygen levels of determined tissues, probably by the reduction of oxidative DNA damage in hypoxic regions, thus leading to a friendlier microenvironment, regarding to clonal expansion and for resistance to chemotherapeutic regimens. Furthermore, there have been strong data indicating a pivotal role of hypoxic niche in cancer stem cells development. There are evidence that hypoxia could drive the maintenance of CSC, via HIF-1α expression, but it still to be determined whether hypoxia markers are expressed in breast tumors presenting CD44+CD24-/low immunophenotype. Methods Immunohistochemical analysis of CD44+CD24-/low expression and its relationship with hypoxia markers and clinical outcome were evaluated in 253 samples of breast ductal carcinomas. Double-immunolabeling was performed using EnVision Doublestain System (Dako, Carpinteria, CA, USA). Slides were then scanned into high-resolution images using Aperio ScanScope XT and then, visualized in the software Image Scope (Aperio, Vista, CA, USA). Results In univariate analysis, CD44+CD24-/low expression showed association with death due to breast cancer (p = 0.035). Breast tumors expressing CD44+CD24-/low immunophenotype showed relationship with HIF-1α (p = 0.039) and negativity for HER-2 (p = 0.013). Conclusion Considering that there are strong evidences that the fraction of a tumour considered to be cancer stem cells is plastic depending upon microenvironmental signals, our findings provide further evidence that hypoxia might be related to the worse prognosis found in CD44+CD24-/low positive breast tumors.

The antinociceptive effect of electroacupuncture at different depths of acupoints and under the needling surface

Background The stimulation of acupoints along the meridians, but not the non-acupoints outside of the meridians, produces analgesia. Although the acupoint is defined at the body surface, the exact location of the acupoints is not known. This study aims to examine whether the intensity and duration of the analgesic effect of electroacupuncture (EA) at the Zusanli (ST36) and Sanynjiao acupoints (SP6) change according to the depth of the stimulation. Methods Ninety-six male Wistar rats classified as responders were arbitrarily allocated into 16 groups of six rats each. Six groups received EA with uninsulated acupuncture needles (type I) or needles that were immersed in varnish and had the varnish circularly peeled 0.2 mm from the tip (type II), 0.2 mm at 3 mm (type III) or 5 mm (type IV) from the tip, or 0.2 mm at 5 and 1 mm from the tip (type V), or EA sham for 20 min. Five groups received injection of formalin into the acupoint bilaterally at 5 mm or 1 mm deep into ST36, 5 mm below ST36 but inserting the needle at 45° to the skin surface, or 5 mm deep into non-acupoints. The remaining groups received intraplantar injection of saline, 1% or 2.5% formalin. The analgesic effects were measured by the rat tail-flick test. Results The bilateral stimulation of ST36 and SP6 by uninsulated or insulated needles produced analgesia in the rat tail-flick test. The stronger and longer lasting effects occurred after EA with the types I and V needles, or injection of formalin 5 mm deep into ST36. The remaining needles produced weaker and shorter lasting effects. Slow analgesic effect also occurred after formalin injection at 1 mm or 5 mm below ST36 by inserting the needle at 45° to the skin surface. Conclusion The experimental results suggest that the efficacy of the EA stimulation depends on the spatial distribution of the current density under the needling surface rather than only the acupoint or the depth of needling.

Influence of palatoplasty on occlusion of patients with isolated cleft palate

OBJECTIVE: This study compared the dental arch morphology of adult patients with isolated cleft palate in order to verify the influence of palatoplasty on occlusion. METHODS: Cast models of 77 patients, 30 males and 47 females, with an average age of 21 years and no syndromes were taken. They were in the permanent dentition and had not undergone orthodontic treatment. The sample was divided into non-operated and operated patients, the latter having been submitted to palatoplasty at a mean age of 2.2 years. RESULTS: Almost 80% of the sample exhibited sagittal discrepancies in the inter-arch relationship, with a Class II malocclusion prevailing (59.74%) followed by Class III (20,78%), regardless of palatoplasty. Transverse analysis showed a 23% incidence of posterior crossbite also not influenced by palatoplasty. Intra-arch relationship indicated that constriction and crowding on the upper arch were more frequent in the operated group (p=0.0238 and p=0.0002, respectively), showing an influence of palatoplasty on its morphology. The predominant morphological characteristics in patients with isolated cleft palate were a Class II malocclusion, upper dental arch constriction and upper and lower anterior crowding. CONCLUSION: The influence of palatoplasty was restricted to constriction and crowding of the upper dental arch, with no interference from the extension of the cleft, except for the upper crowding, which occurred more in patients with complete cleft palates.

Letteratura e realia. Le espressioni culturo-specifiche nelle traduzioni italiane della Wendeliteratur

Il presente lavoro affronta il problema della traduzione dei termini culturo-specifici nella letteratura contemporanea di lingua tedesca ambientata nella DDR. L’analisi della produzione narrativa della Wendeliteratur consente di osservare come il lessico e le espressioni tipiche della DDR vengano utilizzati nelle opere letterarie in funzione citazionale per denotare e connotare la realtà della Germania dell’Est. Attraverso un approccio integrato che coniuga i contributi teorici degli studi sulla traduzione con gli aspetti della pratica traduttiva il lavoro indaga il tema dei realia attraverso una presentazione delle ricerche esistenti, propone una classificazione specifica per i realia della DDR e procede a una ricognizione delle strategie e dei procedimenti traduttivi concreti, che consente di evidenziare le diverse scelte adottate dai traduttori. Attraverso un’analisi ermeneutica dei testi e lo strumento dell’isotopia come indicatore di coerenza le traduzioni italiane delle opere della Wendeliteratur sono oggetto di un’analisi critica. I risultati dell’analisi vengono infine utilizzati come riferimento per la traduzione dei realia nel racconto di F.C. Delius, Die Birnen von Ribbeck.

Entstehung und Dynamik des Keratinfilament-Netzwerks

Das zytoplasmatische Zytoskelett besteht aus drei Filamentsystemen, die aus Aktin, Tubulin und Intermediärfilamentproteinen aufgebaut sind und dreidimensionale Netzwerke ausbilden. Das Intermediärfilamentsystem, dem vor allem mechanische Stabilisierungsfunktionen zugesprochen werden, unterscheidet sich von den anderen durch seine Fähigkeit, spontan aus seinen Polypeptiduntereinheiten ohne weitere Kofaktoren zu polymerisieren und durch seinen unpolaren Aufbau. Es ist bis heute unbekannt, wie Intermediärfilamentnetzwerke in vivo moduliert werden und wie ihre Anordnung in den Kontext des Gesamtzytoskeletts koordiniert wird. Am Beispiel der epithelialen Intermediärfilamentproteine, den Keratinen, sollte daher untersucht werden, wie und wo neue Intermediärfilamente entstehen, welche Bedeutung den anderen Filamentsystemen bei dem Netzwerkaufbau und –Turn-Over zukommen und wie die Netzwerkbildung gesteuert wird. Zur Beantwortung dieser Fragestellungen wurden Zellklone hergestellt, die fluoreszierende Keratine synthetisieren. In der Zelllinie SK8/18-2, deren gesamtes Netzwerk aus derartigen Chimären aufgebaut ist, konnten anhand von mikroskopischen Zeitrafferaufnahmen der Fluoreszenzmuster Keratinfilamentvorläufer (KFP) identifiziert und deren Dynamik direkt in lebenden Zellen verfolgt werden. Es konnte gezeigt werden, dass die KFP in einem Plasmamembran-nahen Bereich entstehen, in dem sie zuerst als punktförmige Partikel detektiert werden. Nach einer initialen, sphäroidalen Wachstumsphase elongieren die Partikel zu kleinen Filamentstückchen. Diese können miteinander fusionieren und werden über ihre Enden in das periphere Netzwerk integriert. Der Wachstumsprozess ist gekoppelt an eine kontinuierliche, langsame Bewegung in Richtung auf das Zellzentrum. Diese Motilität sistiert vollständig nach pharmakologisch induziertem Abbau der Aktinfilamente. In Zeitraffer-aufnahmen kann jedoch in derartig behandelten Zellen ein wesentlich schnellerer Transport, der in verschiedene Richtungen verläuft und durch lange Ruhephasen unterbrochen wird, beobachtet werden. Dieser Modus, der gelegentlich auch in unbehandelten Zellen gefunden wurde, ist abhängig von intakten Mikrotubuli. Erst durch Zerstörung der Aktinfilamente und der Mikrotubuli erlischt die Motilität der KFPs vollständig. Bei der Suche nach Regulatoren der Keratinnetzwerkbildung wurde die p38 MAPK als zentraler Faktor identifiziert. Erstmals konnte eine direkte räumliche und zeitliche Korrelation zwischen einer spezifischen Enzymaktivität durch Nachweis der phosphorylierten p38 MAPK, der daraus folgenden Phosphorylierung eines Keratins, hier Serin 73 des Keratin 8, und der daraus resultierenden Veränderung des Netzwerkaufbaus, d. h. der Ausbildung von Keratingranula, nachgewiesen werden. Diese koordinierten Veränderungen wurden in unterschiedlichen Stresssituationen in verschiedenen Zellsystemen und in Zellen mit mutierten Keratinen beobachtet. Genetische (shRNA) und pharmakologische Manipulationen der p38 MAPK-Aktivität deuten auf einen engen kausalen Zusammenhang hin.

Reti di contratti e reti di imprese

Il lavoro di ricerca prende le mosse da una premessa di ordine economico. Il fenomeno delle reti di impresa, infatti, nasce dalla realtà economica dei mercati. In tale contesto non può prescindere dal delineare un quadro della situazione- anche di crisi- congiunturale che ha visto coinvolte specialmente le imprese italiane. In tale prospettiva, si è reso necessario indagare il fenomeno della globalizzazione, con riferimento alle sue origini,caratteristiche e conseguenze. Ci si sofferma poi sulla ricostruzione dogmatica del fenomeno. Si parte dalla ricostruzione dello stesso in termini di contratto plurilaterale- sia esso con comunione di scopo oppure plurilaterale di scambio- per criticare tale impostazione, non del tutto soddisfacente, in quanto ritenuto remissiva di fronte alla attuale vis espansiva del contratto plurilaterale. Più convincente appare lo schema del collegamento contrattuale, che ha il pregio di preservare l’autonomia e l’indipendenza degli imprenditori aderenti, pur inseriti nel contesto di un’operazione economica unitaria, volta a perseguire uno scopo comune, l’“interesse di rete”, considerato meritevole di tutela secondo l’ordinamento giuridico ex art. 1322 2.co. c.c. In effetti il contratto ben si presta a disegnare modelli di rete sia con distribuzione simmetrica del potere decisionale, sia con distribuzione asimmetrica, vale a dire con un elevato livello di gerarchia interna. Non può d’altra parte non ravvisarsi un’affinità con le ipotesi di collegamento contrattuale in fase di produzione, consistente nel delegare ad un terzo parte della produzione, e nella fase distributiva, per cui la distribuzione avviene attraverso reti di contratti. Si affronta la materia della responsabilità della rete, impostando il problema sotto due profili: la responsabilità interna ed esterna. La prima viene risolta sulla base dell’affidamento reciproco maturato da ogni imprenditore. La seconda viene distinta in responsabilità extracontrattuale, ricondotta nella fattispecie all’art. 2050 c.c., e contrattuale.

Unconventional superconductivity of the heavy fermion compound UNi 2 Al 3

The heavy fermion compound UNi2Al3 exhibits the coexistence of superconductivity and magnetic order at low temperatures, stimulating speculations about possible exotic Cooper-pairing interaction in this superconductor. However, the preparation of good quality bulk single crystals of UNi2Al3 has proven to be a non-trivial task due to metallurgical problems, which result in the formation of an UAl2 impurity phase and hence a strongly reduced sample purity. The present work concentrates on the preparation, characterization and electronic properties investigation of UNi2Al3 single crystalline thin film samples. The preparation of thin films was accomplished in a molecular beam epitaxy (MBE) system. (100)-oriented epitaxial thin films of UNi2Al3 were grown on single crystalline YAlO3 substrates cut in (010)- or (112)-direction. The high crystallographic quality of the samples was proved by several characterisation methods, such as X-ray analysis, RHEED and TEM. To study the magnetic structure of epitaxial thin films resonant magnetic x-ray scattering was employed. The magnetic order of thin the film samples, the formation of magnetic domains with different moment directions, and the magnetic correlation length were discussed. The electronic properties of the UNi2Al3 thin films in the normal and superconducting states were investigated by means of transport measurements. A pronounced anisotropy of the temperature dependent resistivity ρ(T) was observed. Moreover, it was found that the temperature of the resistive superconducting transition depends on the current direction, providing evidence for multiband superconductivity in UNi2Al3. The initial slope of the upper critical field H′c2(T) of the thin film samples suggests an unconventional spin-singlet superconducting state, as opposed to bulk single crystal data. To probe the superconducting gap of UNi2Al3 directly by means of tunnelling spectroscopy many planar junctions of different design employing different techniques were prepared. Despite the tunneling regime of the junctions, no features of the superconducting density of state of UNi2Al3 were ever observed. It is assumed that the absence of UNi2Al3 gap features in the tunneling spectra was caused by imperfections of the tunnelling contacts. The superconductivity of UNi2Al3 was probably suppressed just in a degraded surface layer, resulting in tunneling into non superconducting UNi2Al3. However, alternative explanations such as intrinsic pair breaking effects at the interface to the barrier are also possible.

The Dynamics of Passive Torsional Fatigue Test Rigs: Innovative Applications of Universal Joints

The dynamics of a passive back-to-back test rig have been characterised, leading to a multi-coordinate approach for the analysis of arbitrary test configurations. Universal joints have been introduced into a typical pre-loaded back-to-back system in order to produce an oscillating torsional moment in a test specimen. Two different arrangements have been investigated using a frequency-based sub-structuring approach: the receptance method. A numerical model has been developed in accordance with this theory, allowing interconnection of systems with two-coordinates and closed multi-loop schemes. The model calculates the receptance functions and modal and deflected shapes of a general system. Closed form expressions of the following individual elements have been developed: a servomotor, damped continuous shaft and a universal joint. Numerical results for specific cases have been compared with published data in literature and experimental measurements undertaken in the present work. Due to the complexity of the universal joint and its oscillating dynamic effects, a more detailed analysis of this component has been developed. Two models have been presented. The first represents the joint as two inertias connected by a massless cross-piece. The second, derived by the dynamic analysis of a spherical four-link mechanism, considers the contribution of the floating element and its gyroscopic effects. An investigation into non-linear behaviour has led to a time domain model that utilises the Runge-Kutta fourth order method for resolution of the dynamic equations. It has been demonstrated that the torsional receptances of a universal joint, derived using the simple model, result in representation of the joint as an equivalent variable inertia. In order to verify the model, a test rig has been built and experimental validation undertaken. The variable inertia of a universal joint has lead to a novel application of the component as a passive device for the balancing of inertia variations in slider-crank mechanisms.

Surface patterning with colloidal monolayers

This thesis focuses on the controlled assembly of monodisperse polymer colloids into ordered two-dimensional arrangements. These assemblies, commonly referred to as colloidal monolayers, are subsequently used as masks for the generation of arrays of complex metal nanostructures on solid substrates.rnThe motivation of the research presented here is twofold. First, monolayer crystallization methods were developed to simplify the assembly of colloids and to produce more complex arrangements of colloids in a precise way. Second, various approaches to colloidal lithography are designed with the aim to include novel features or functions to arrays of metal nanostructures.rnThe air/water interface was exploited for the crystallization of colloidal monolayer architectures as it combines a two-dimensional confinement with a high lateral mobility of the colloids that is beneficial for the creation of high long range order. A direct assembly of colloids is presented that provides a cheap, fast and conceptually simple methodology for the preparation of ordered colloidal monolayers. The produced two-dimensional crystals can be transformed into non-close-packed architectures by a plasma-induced size reduction step, thus providing valuable masks for more sophisticated lithographic processes. Finally, the controlled co-assembly of binary colloidal crystals with defined stoichiometries on a Langmuir trough is introduced and characterized with respect to accessible configurations and size ratios. rnSeveral approaches to lithography are presented that aim at introducing different features to colloidal lithography. First, using metal-complex containing latex particles, the synthesis of which is described as well, symmetric arrays of metal nanoparticles can be created by controlled combustion of the organic material of the colloids. The process does not feature an inherent limit in nanoparticle size and is able to produce complex materials as will be demonstrated for FePt alloy particles. Precise control over both size and spacing of the particle array is presented. rnSecond, two lithographic processes are introduced to create sophisticated nanoparticle dimer units consisting of two crescent shaped nanostructures in close proximity; essentially by using a single colloid as mask to generate two structures simultaneously. Strong coupling processes of the parental plasmon resonances of the two objects are observed that are accompanied by high near-field enhancements. A plasmon hybridization model is elaborated to explain all polarization dependent shifts of the resonance positions. Last, a technique to produce laterally patterned, ultra-flat substrates without surface topographies by embedding gold nanoparticles in a silicon dioxide matrix is applied to construct robust and re-usable sensing architectures and to introduce an approach for the nanoscale patterning of solid supported lipid bilayer membranes. rn

Traduzione del primo canto dell'inferno dantesco in arabo

In this thesis, I have chosen to translate from Italian into Arabic Canto I of the Inferno, from Dante Alighieri’s epic poem the Divine Comedy (La Divina Commedia) because it’s a masterpiece in both Italian and world literature. Also I have selected it for its artistic value and the universal themes that it depicts. In fact, my purpose in translating this great work into Arabic is to extol the cultural and universal aspects that can be common to human beings everywhere. My paper is written in Arabic and has six sections: A brief introduction on Dante’s life, an introduction to the Divine Comedy, a summary of Canto 1 of the Inferno and its analysis, Canto I of the Inferno in Italian, its translation into Arabic and finally a comment on the translation. The first part -a summary of Dante’s life was presented. The second part of my paper is an introduction to the Divine Comedy, the allegorical epic poem, consisting of three parts: The Inferno (Hell), Purgatorio (Purgatory), and Paradiso (Paradise). The third part is a summary and analysis of Canto 1 of the Inferno, Dante’s most renowned verses. The analysis of Canto highlights the everlasting conflict of man– sinning and giving in to temptation but then trying to repent and search for his soul’s salvation. He reflects on sin, existence, truth, God, love and salvation in his struggle through the dark and gloomy forest which symbolizes conflict and temptations man may succumb to. The influence of Christianity and the Middle ages here shows his commitment to religion and faith. Moreover, his meeting of Virgil, who guides him to the mountain during his journey to salvation, reflects the positive impact of Virgil’s philosophy on Dante. The fourth part presents the Italian version of Canto 1 of the Inferno. The fifth section of my paper is the translation of Canto 1 of the Inferno from Italian to Arabic. Translating an excerpt of Dante’s masterpiece was not an easy task: I had to consult several critique texts besides the Italian source text with explanations, and also some English versions to overcome any translation difficulties. As a student of translation, my goal was to be faithful in relaying to the Arabic audience the authenticity of Dante’s work, his themes, passions and aesthetic style. Finally, I present a conclusion including a comment on the translation and the bibliography of the sources I have consulted.

Internazionalizzazione e traduzione: Un'esperienza presso l'azienda TR Turoni S.R.L.

This dissertation was conducted within the project Language Toolkit, which has the aim of integrating the worlds of work and university. In particular, it consists of the translation into English of documents commissioned by the Italian company TR Turoni and its primary purpose is to demonstrate that, in the field of translation for companies, the existing translation support tools and software can optimise and facilitate the translation process. The work consists of five chapters. The first introduces the Language Toolkit project, the TR Turoni company and its relationship with the CERMAC export consortium. After outlining the current state of company internationalisation, the importance of professional translators in enhancing the competitiveness of companies that enter new international markets is highlighted. Chapter two provides an overview of the texts to be translated, focusing on the textual function and typology and on the addressees. After that, manual translation and the main software developed specifically for translators are described, with a focus on computer-assisted translation (CAT) and machine translation (MT). The third chapter presents the target texts and the corresponding translations. Chapter four is dedicated to the analysis of the translation process. The first two texts were translated manually, with the support of a purpose-built specialized corpus. The following two documents were translated with the software SDL Trados Studio 2011 and its applications. The last texts were submitted to the Google Translate service and to a process of pre and post-editing. Finally, in chapter five conclusions are drawn about the main limits and potentialities of the different translations techniques. In addition to this, the importance of an integrated use of all available instruments is underlined.

Molecular genetic causes of columnar growth in apple (Malus x domestica)

The columnar growth habit of apple is interesting from an economic point of view as the pillar-like trees require little space and labor. Genetic engineering could be used to speed up breeding for columnar trees with high fruit quality and disease resistance. For this purpose, this study dealt with the molecular causes of this interesting phenotype. The original bud sport mutation that led to the columnar growth habit was found to be a novel nested insertion of a Gypsy-44 LTR retrotransposon on chromosome 10 at 18.79 Mb. This subsequently causes tissue-specific differential expression of nearby downstream genes, particularly of a gene encoding a 2OG-Fe(II) oxygenase of unknown function (dmr6-like) that is strongly upregulated in developing aerial tissues of columnar trees. The tissue-specificity of the differential expression suggests involvement of cis-regulatory regions and/or tissue-specific epigenetic markers whose influence on gene expression is altered due to the retrotransposon insertion. This eventually leads to changes in genes associated with stress and defense reactions, cell wall and cell membrane metabolism as well as phytohormone biosynthesis and signaling, which act together to cause the typical phenotype characteristics of columnar trees such as short internodes and the absence of long lateral branches. In future, transformation experiments introducing Gypsy-44 into non-columnar varieties or excising Gypsy-44 from columnar varieties would provide proof for our hypotheses. However, since site-specific transformation of a nested retrotransposon is a (too) ambitious objective, silencing of the Gypsy-44 transcripts or the nearby genes would also provide helpful clues.

Traduzione tecnica e internazionalizzazione d'impresa: Il caso di Technologica S.r.l.

This dissertation is part of the Language Toolkit project which is a collaboration between the School of Foreign Languages and Literature, Interpreting and Translation of the University of Bologna, Forlì campus, and the Chamber of Commerce of Forlì-Cesena. This project aims to create an exchange between translation students and companies who want to pursue a process of internationalization. The purpose of this dissertation is demonstrating the benefits that translation systems can bring to businesses. In particular, it consists of the translation into English of documents supplied by the Italian company Technologica S.r.l. and the creation of linguistic resources that can be integrated into computer-assisted translation (CAT) software, in order to optimize the translation process. The latter is claimed to be a priority with respect to the actual translation products (the target texts), since the analysis conducted on the source texts highlighted that the company could streamline and optimize its English language communication thanks to the use of open source CAT tools such as OmegaT. The work consists of five chapters. The first introduces the Language Toolkit project, the company (Technologica S.r.l ) and its products. The second chapter provides some considerations about technical translation, its features and some misconceptions about it. The difference between technical translation and scientific translation is then clarified and an overview is offered of translation aids such as those used for computer-assisted translation, machine translation, termbases and translation memories. The third chapter contains the analysis of the texts commissioned by Technologica S.r.l. and their categorization. The fourth chapter describes the translation process, with particular attention to terminology extraction and the creation of a bilingual glossary based on a specialized corpus. The glossary was integrated into the OmegaT software in order to facilitate the translation process both for the present task and for future applications. The memory deriving from the translation represents a sort of hybrid resource between a translation memory and a glossary. This was found to be the most appropriate format, given the specific nature of the texts to be translated. Finally, in chapter five conclusions are offered about the importance of language training within a company environment, the potentialities of translation aids and the benefits that they would bring to a company wishing to internationalize itself.
