The aim of this work was to study the influence of vitamin E (2mM) on capacitation and acrosome reaction of crossbred cattle bull spermatozoa. Fresh semen suspended in TALP medium (pH 7.4) was divided into four equal fractions. All fractions; control (containing TALP + spermatozoa) and the experimental [treated / untreated with ferrous ascorbate (FeAA – 150 μM FeSO4 : 750 μM ascorbic acid); sup...

The site of sperm capacitation, the agents and mechanisms causing capacitation and acrosome reaction (AR) in vivo are not well understood. The female reproductive tract has been reported to play a key role during capacitation and AR. Some experiments were carried out on the capacitation and AR of hamster epididymal spermatozoa in the estrogen and progesterone dominated uterus (estrous and diest...

O estudo buscou identificar as representações sociais dos consumidores de cafés especiais na Cafeteria Escola CafEsal da Universidade Federal Lavras (UFLA), a partir do diálogo entre concepções teóricas Consumer Culture Theory (CCT) e Teoria das Representações Sociais (TRS). A pesquisa seguiu uma abordagem qualitativa com coleta dados via formulários uso Técnica Associação Livre Palavras (TALP)...

The “Meaning” system has been developed within the framework of the Meaning European research project1 . It is a combined system, which integrates several supervised machine learning word sense disambiguation modules, and several knowledge– based (unsupervised) modules. See section 2 for details. The supervised modules have been trained exclusively on the SemCor corpus, while the unsupervised m...

Este estudo analisou as representações sociais do trânsito para motoristas brasileiros. Participaram 110 pessoas, com idades entre 19 e 62 anos (M = 27,9; DP 9,44), de diferentes regiões Brasil. Os sujeitos responderam a um questionário sociodemográfico teste associação livre palavras (TALP) os estímulos indutores “motociclistas”, “pedestres” “engarrafamento”. resultados demonstraram que motori...

BACKGROUND Bone metastases are devastating events resulting in disruption of local bone remodeling processes. Physiological bone turnover has a circadian rhythm. No data are available on the circadian pattern of bone turnover markers in patients with bone metastases. METHODS Twenty post-menopausal women with breast cancer (BC) at first disease relapse and at least one bone metastasis were con...

This paper describes TALPtuples, the 2006 Ngrambased statistical machine translation system developed at the TALP Research Center of the UPC (Universitat Politècnica de Catalunya) in Barcelona. Emphasis is put on improvements and extensions of the system of previous years, being highlighted and empirically compared. Mainly, these include a novel and much more efficient word ordering strategy ba...

Background: Nowadays, cryoprotectant-free vitrification of human sperm in large or small volumes facilitated storage and use of human sperm for long time. However, this procedure was not successful in farm animals. The main finding in the studies is higher sensitivity of these kinds of sperm to sucrose osmolarities. Preliminary studies showed a reversible effect of sucrose on goat epididymal sp...

This paper describes TALPtuples, the 2007 N -gram-based statistical machine translation system developed at the TALP Research Center of the UPC (Universitat Politècnica de Catalunya) in Barcelona. Emphasis is put on improvements and extensions of the system of previous years. Mainly, these include optimizing alignment parameters in function of translation metric scores and rescoring with a neur...

This paper reports translation results for the “Exploiting Parallel Texts for Statistical Machine Translation” (HLT-NAACL Workshop on Parallel Texts 2006). We have studied different techniques to improve the standard Phrase-Based translation system. Mainly we introduce two reordering approaches and add morphological information.
