This article aims to investigate the abbreviations used on chats by web-surfers between 15 and 20 years old. The material consists of two virtual conversations of about 60 minutes each. We believe that this linguistic process occurs due to the physical distance that separates affectively the web-surfers by modifying already said utterances in written practices characterized by short time of interaction. This abbreviation process, known as a characteristic of the so called internetês, is not considered as a simple attempt to cut the words, but as a resource that presents linguistics' regularity. Therefore, the theory of phonological syllable is used as a tool in order to verify the process that forms possible abbreviations used on chats. It is believed that, based on the study of the syllable structure, the choice of the graphemes abbreviation may be assessed based on the writing heterogeneity, since the writer might not only use oral/spoken practices but also literate/written ones so as to produce utterances that emerge in the contemporaneity.

Reflexõs sobre a linguagem do ambiente chat no Teletandem sob a perspectiva da natureza heterogênea da escrita

This paper aims at discussing the characteristics of computer mediated language within a foreign language teaching and learning environment enabled by the use of synchronic writing resources – chat. The present research is based on (i) theoretical principles about the use of technologies and the teaching-learning of foreign languages in the scope of the Teletandem Brazil Project: Foreign languages for all – Projeto Teletandem Brasil: línguas estrangeiras para todos (TELLES, 2005); (ii) studies on the characteristics of the language within chat interactions; (iii) different theoretical perspectives on the relationship between spoken and written language, emphasizing the constitutive heterogeneity of writing perspective (CORRÊA, 1997, 1998, 2001); and (iv) some relevant concepts related to Prosodic Phonology field (NESPOR; VOGEL, 1986). Is being taken as research data, the written production of a Brazilian student (finishing a Licentiate in Literature) interacting with an American student (in Religious Studies) through Windows Live Messenger. The data were collected during a five-month period, during which the participants interacted through chat, totalizing 12 interactions in English and in Portuguese. During the analysis, a particular attention was given to the messages’ fragmentation, the use (or not) of punctuation signs and abbreviations within the Brazilian participant’s production, in order to discuss the representations she built of her writing, her interlocutor, herself and on the teaching-learning process of a foreign language.

Catalogue of the type material of Neriidae (Diptera, Schizophora) in the collection of the Museum fur Naturkunde Berlin, Germany

The Diptera collection of the Natural History Museum Berlin holds one of the most important collections of Neriidae. In this paper, the type specimens (holotypes, lectotypes, paratypes, paralectotypes, syntypes) of this historical collection are listed. 28 species-group taxa are dealt with. A lectotype designation is made for the species Brachantichir purpusianus Enderlein, 1922 in order to fix the identity of the name. Holotypes are recognized by monotypy of the species Chaetomeristes bullatus Enderlein, 1922; Chaetomeristes peruanus Enderlein, 1922; Derocephalus angusticollis Enderlein, 1922; Glyphidops limbatus Enderlein, 1922; Longina abdominalis Wiedemann, 1830; Loxozus clavicornis Enderlein, 1922; Oncopsia mexicana Enderlein, 1922; Paranerius fibulatus Enderlein, 1922; Telostylinus dahli Enderlein, 1922; Telostylus latibrachium Enderlein, 1922; and Telostylinus luridus Enderlein, 1922. Syntypes are labelled and listed for Brachantichir robusta Enderlein, 1922; Nerius terebratus Enderlein, 1922; Odontoloxozus punctulatus Enderlein, 1922; Telostylinus apicalis Enderlein, 1922; Telostylinus obscuratus Enderlein, 1922; and Telostylinus ornatipennis Enderlein, 1922. The account concludes with geographic and taxonomic summaries; an appendix listing the abbreviations, localities, and collectors cited in the text; and a bibliography.

Die Abschrift als Schreibszene. Der ›Nuwe Parzifal‹ in der Handschrift Rom, Biblioteca Casanatense, Mss. 1409

The Codex Biblioteca Casanatense 1409 which has for a long time been neg- lected in Parzival scholarship, transmits German translations of three continuations of Chre ́tien de Troyes‘ Roman de Perceval ou Le Conte du Graal together with the last two books (XV/XVI) of Wolfram von Eschenbach’s Parzival. This article supports the for- merly casually made assumption that the Casanatense manuscript is in fact a direct copy of Codex Donaueschingen 97, the so called Rappoltsteiner Parzifal. As is to be shown, marks in the Donaueschingen codex, as well as significant copying errors in the Casanatense text and its treatment of initials suggest a direct relationship of the two witnesses. The notion of ,writing scene‘ (Schreibszene) with its implications of linguistic semantics, instrumentality, gesture and self reflection, proposed in modern literary scholarship, can help to understand peculiarities of the copying process in the Casanatensis, such as the numerous conceptual abbreviations and the adaptations in the handling of headings. In the final part of the article, the hypothesis is corroborated, that the copy of the Casa- natensis might have been produced in the surroundings of Lamprecht von Brunn (ca. 1320–1399), bishop of Strasburg and Bamberg, and counsellor of the emperor Charles IV.

Nerve Transfers for Persistent Traumatic Peroneal Nerve Palsy: The Inselspital Bern Experience

BACKGROUND Patients in whom conventional peroneal nerve repair surgery failed to reconstitute useful foot lift need to be evaluated for their suitability to undergo a concomitant tendon transfer procedure or nerve transfers. OBJECTIVE To report our first clinical experience with nerve transfers for persistent traumatic peroneal nerve palsy. METHODS Between 2007 and 2013, 8 patients were operated on for foot drop after unsuccessful nerve surgery. Six patients without fatty degeneration of the anterior tibial muscle and proximal lesion of the peroneal nerve were oriented for tibial to peroneal nerve transfer. In the other 2 cases where the anterior and lateral compartments were destructed, the anterior tibial muscle function was reconstructed with a neurotized lateral gastrocnemius transfer. For each patient, we graded postoperative results using the Bureau of Meteorology Research Centre scheme and the Ninkovic assessment scale. RESULTS Of the 6 patients who underwent nerve transfer of the anterior tibial muscle, 2 patients had excellent results, 1 patient had good results, 1 patient had fair results, and 2 patients had poor results. Of the 2 patients that underwent neurotized lateral gastrocnemius transfer, 1 patient achieved excellent results after tenolysis, whereas 1 patient achieved poor results. After the nerve transfer, 5 patients did not wear an ankle-foot orthosis. Four patients did not limp. Four patients were able to walk barefoot, navigate stairs, and participate in activities. CONCLUSION Early clinical results after tibial to peroneal nerve transfer and neurotized lateral gastrocnemius transfer appear mixed. The results of nerve transfer seem, on the whole, less reliable than the literature reports on tendon transfer. ABBREVIATIONS EMG, electromyographyNAP, nerve action potential.

The Risk of Seizure After Surgery for Unruptured Intracranial Aneurysms: A Prospective Cohort Study.

BACKGROUND We aimed to identify a group of patients with a low risk of seizure after surgery for unruptured intracranial aneurysms (UIA). OBJECTIVE To determine the risk of seizure after discharge from surgery for UIA. METHODS A consecutive prospectively collected cohort database was interrogated for all surgical UIA cases. There were 726 cases of UIA (excluding cases proximal to the superior cerebellar artery on the vertebrobasilar system) identified and analyzed. Cox proportional hazards regression models and Kaplan-Meier life table analyses were generated assessing risk factors. RESULTS Preoperative seizure history and complication of aneurysm repair were the only risk factors found to be significant. The risk of first seizure after discharge from hospital following surgery for patients with neither preoperative seizure, treated middle cerebral artery aneurysm, nor postoperative complications (leading to a modified Rankin Scale score >1) was <0.1% and 1.1% at 12 months and 7 years, respectively. The risk for those with preoperative seizures was 17.3% and 66% at 12 months and 7 years, respectively. The risk for seizures with either complications (leading to a modified Rankin Scale score >1) from surgery or treated middle cerebral artery aneurysm was 1.4% and 6.8% at 12 months and 7 years, respectively. These differences in the 3 Kaplan-Meier curves were significant (log-rank P < .001). CONCLUSION The risk of seizures after discharge from hospital following surgery for UIA is very low when there is no preexisting history of seizures. If this result can be supported by other series, guidelines that restrict returning to driving because of the risk of postoperative seizures should be reconsidered.

Geochemistry of basement clasts from sediment core CRP-3 in the ross Sea, Antarctica

Distribution patterns and petrographical and mineral chemistry data are described for the most representative basement lithologies occuring as clast in the c. 824 m thick Tertiary sedimentary sequence at the CRP-3 drillsite. These are granule to bolder grain size clasts of igneous and metamorphic rocks. Within the basement clast assemblage, granitoid pebbles are the predominant lithology. They consist of dominant grey biotic-bearing monzogranite, pink biotite-hornblende monzogranite, and biotite-bearing leucomomonzgranite. Minor lithologies include: actinolite-bearing leucotonalite, microgranite, biotite-hornblende quartz-monzonitic porphyr, and foliated biotic leucomonzogranite. Metamorphic clasts include rocks of both granitic and sedimentary derivation. They include mylonitic biotic orthogneiss, with or without garnet, muscovite-bearing quartzite, sillimanite-biotite paragneiss, biotite meta-sandstone, biotite-spotted schist, biotite-clacite-clinoamphibole meta-feldspathic arenite, biotite-calcite-clinozoisite meta-siltstone, biotite±clinoamphibole meta-marl, and graphite-bearing marble. As in previous CRP drillcores, the ubiquitous occurence of biotite±hornblende monzogranite pebbles is indicative of a local provenance, closely mirroring the dominance of these lithologies in the on-shore basement, where the Cambro-Ordovician Granite Harbour Intrusive Complex forms the most extensively exposed rock unit.

Análisis de salto vertical repetido en jugadores de baloncesto

Con el propósito de analizar los cambios de la fuerza máxima explosiva en relación a la ejecución de series de salto vertical repetido (SVR) con periodos cortos de recuperación pasiva en jugadores de baloncesto, se evaluaron 12 deportistas en un protocolo de cuatro series (S) de 15-s de saltos verticales con 10-s de recuperación entre S. Se midieron la altura de salto inicial (ASI) y final (ASF) de cada S; se utilizó ANOVA de una vía con post hoc de Bonferroni para el análisis de las diferencias ASF-ASI por S y una prueba t de Student para analizar el índice de fatiga (IF) por serie. Se encontró que la diferencia ASF-ASI fue progresivamente incremental desde la S1 hasta la S4 (-2,8 6,2 cm, -6,8 4,9 cm, -8,4 5,6 cm y -9,3 5,9 cm, respectivamente), aunque la diferencia fue mayor solo en S4 con respecto a S1 (p=0,014). Es posible que los períodos de recuperación entre cada S influyeron en el mantenimiento de la fuerza muscular explosiva (FME) durante los primeros 45-s de saltos, sin embargo, la suma de estas ejecuciones generó un aumento de la fatiga al final de la prueba. La FME puede ser afectada por la suma de ejecuciones de SVR aun con la inclusión de períodos cortos de recuperación entre series. La relación trabajo-recuperación en baloncesto es un factor que debe considerarse para planificar el entrenamiento en jugadores de baloncesto.

Products of chlorophyll diagenesis from DSDP Leg 57 Holes

Tetrapyrrole pigments isolated from sediments retrieved during Leg 57 include pheophytin-a, a myriad of chlorins, free-base deoxophylloerythroetioporphyrin (DPEP), as well as copper and nickel porphyrins. Their richness, both qualitatively and quantitatively, in chlorin tetrapyrroles affords a relatively complete study on the early diagenesis of chlorophyll. Our studies, coupled with those in the preceding chapter by Louda et al., point out the influence of pre- and postdepositional environments upon the mode of chlorophyll diagenesis. Formation of tetrapyrroles, collectively called "petroporphyrins," is seen to occur in only a limited set of environmental conditions (see Baker and Palmer, 1978). The more generalized route of chlorophyll diagenesis, at least in the ocean, results in removal of tetrapyrrole pigment, from the fossil record. Late diagenetic products, metalloporphyrins, are found to represent an extremely minor component of the tetrapyrrole assemblage in sediments studied from the Japan Trench. The products of chlorophyll diagenesis isolated from Japan Trench sediments allow expansion of previous diagenetic schemes (Baker and Palmer, 1978; Triebs, 1936) and indicate directions for future studies.
