The study of the nervous system is increasing in Veterinary Medicine. Transcranial ultrasonography (TCUS) has the advantage of being a non-invasive and low cost method compared to computerized tomography (CT) and Magnetic Resonance Imaging (MRI). The temporal bone has been used as an acoustic window in TCUS in humans. This study aimed to correlate transcranial ultrasonographic images obtained through the temporal and occipital window with healthy dog's encephalic anatomy, and to standardize the technique. 37 adult mongrel dogs were used: 30 animals in vivo, in order to perform USTC screening and seven dog corpses for brain section as well as USTC planes. Data analysis was accomplished by the non parametric Wilcoxon test. Results obtained indicate that TCUS (in dorsal and oblique planes) is a viable method for brain evaluation in dogs weighting up to 10kg without anesthesia.

The objectives of this study were to describe the potential for nitrogen retention by two techniques: comparative slaughter and nitrogen balance; compare the adjusted models for each technique and estimate the maintenance requirement for pullets. Assays were performed during 14 to 28, 56-70 and 98 to 112 days of age, using 168 pullets. The design was completely randomized with seven treatments and eight replications. Treatments consisted of protein levels ranging from 75 to 435gkg-1 of dry matter. The variables were collected by comparative slaughter and nitrogen ingested and deposited in nitrogen balance technique intake and nitrogen excretion. The intercept of the exponential relationship between ingested and excreted nitrogen was considered a requirement for maintenance. The adjusted models were compared by using the maximum likelihood ratio. The techniques described differently compared the requirement for maintenance of nitrogen. For comparative slaughter requiring maintenance was estimated at 342, 372 and 543mg/kgPC0,67 and for nitrogen balance was 342, 225 and 284mg/kgPC0,67 for the period of 14 to 28, 56-70 and 98 to 112 days of age, respectively.

Functional grammar currently has a great acceptance in linguistics, mainly because it can enlighten grammatical facts' motivation in the structure of a text. From its emergence, the tradition of studying grammar by grammar has come to an end. Demonstrative pronouns, for instance, have begun to be viewed as efficient tools of text cohesion, used to resume terms from previous clauses. This task, however, ends up leaving an endless trail of black boxes. How is it possible to explain the origin of demonstratives' anaphoric functioning if they are originally used to indicate things or people relative to the interlocutors' spatial position? This work aims at showing that Cognitive Linguistics arises just as an option for opening those black boxes. This article focuses on one of its themes - the conceptual blending theory - to support this possibility. Firstly, it was necessary to integrate the cognitive model into the complexity theory, according to Bybee (2010) and Castilho (2009), who understand language as a complex adaptive system. After that, a brief updated description on the conceptual blending theory is made and its application in some grammatical facts of the Brazilian Portuguese language is suggested under the morphological and syntactic levels.

Techniques of image capture have advanced along with the technologies of information and communication and unthinkable numbers of information available and imagery are stored in digital environments. The objective of this study is point out difficulties found in the construction of imagetic representations of digital resources using the instruments available for the treatment of descriptive information. The results we have the mapping of descriptive elements to digital images derived from analyzing of the schemes to guide the construction of descriptive records (AACR2R, ISBD, Graphic Materials, RDA, CDWA, CCO) and the conceptual model FRBRer. The result of this analysis conducted the conceptual model, Functional Requirements for Digital Imagetic Data RFDID to the development of more efficient ways to represent the use of imagery in order to make it available, accessible and recoverable from the data persistence descriptive, flexibility, consistency and integrity as essential requirements for the representation of the digital image.

This study was aimed to analyze a procedure that makes the description of pictures in printed text from a book that promotes accessibility for blind people. In addition, the study was aimed to analyze the reformulations suggested by the judges and the index of agreement between researcher and judges. The descriptions were submitted to judges to evaluate the content of the material. The results were obtained through the analysis of two assessments: 1) agreement rate ‒ between the researcher and judges A and B, and between judge A and judge B and 2) analysis of the suggested reformulation. In quantitative terms, the results indicated that the material described achieved a high reliability. In qualitative terms, the reliability achieved represents the quality of the material offered, with well structured descriptions where writing meaning is equivalent to image information, fulfilling the purpose to present in printed text the elements represented in the pictures, effectively conveying their meaning.

Os carrapatos são ectoparasitas hematófagos de grande importância epidemiológica, pois são vetores de muitos patógenos. Esses animais pertencem ao Filo Arthropoda, Classe Arachnida, Subclasse Acari, são classificados em três famílias: Ixodidae, Argasidae e Nutalliellidae, apresentam ampla distribuição geográfica e podem parasitar grande variedade de vertebrados, inclusive o homem. O carrapato da espécie Amblyomma cajennense, popularmente conhecido como carrapato-estrela, carrapato do cavalo ou rodoleiro, tem grande importância médica por ser vetor da bactéria Rickettsia rickettsii, causadora da febre maculosa brasileira (FMB), que pode levar o hospedeiro a óbito. Apesar das crescentes pesquisas com esses animais, ainda existem lacunas na literatura acerca de alguns de seus processos reprodutivos. Dessa forma, esse trabalho teve por objetivo estudar o desenvolvimento dos testículos dessa espécie por meio da descrição da morfologia e histologia dos testículos de indivíduos em jejum e alimentados, identificando a dinâmica do processo de espermatogênese e se a alimentação influencia nesse processo. Os resultados obtidos mostraram que os testículos são estruturas pares e tubulares arranjadas dorsolateralmente no opistossoma, sendo que a região proximal está conectada às vesículas seminais pelos ductos deferentes, semelhante ao observado em outras espécies de ixodídeos. Associado ao aparelho genital masculino encontra-se um complexo de glândulas acessórias multilobuladas. Foi constatado que a alimentação tem papel fundamental no desenvolvimento do sistema reprodutor, visto que nos indivíduos em jejum as vesículas seminais e o complexo de glândulas acessórias foram menores e menos desenvolvidos do que nos animais alimentados. Além disso, as espermátides alongadas, precursoras dos espermatozoides no trato reprodutor... (Resumo completo, clicar acesso eletrônico abaixo)
