Resumo Este estudo tem como objetivo avaliar a influência da adição de esporos de B. subtilis AP91 nas propriedades mecânicas de argamassas. Para tanto, a bactéria B. subtilis AP91 isolada de folhas de arroz da variedade agulha precoce foi utilizada na concentração de 105 esporos/mL em argamassas com traço de 1:3 (em massa) e relação água/cimento (a/c) de 0,63. Os esporos bacterianos foram adicionados de duas diferentes formas: na água de amassamento e por imersão em solução contendo os esporos. A análise por Microscopia Eletrônica de Varredura (MEV) com Sistema de Energia Dispersiva (EDS) mostrou cristais com picos de cálcio, o que possivelmente indica a presença de carbonato de cálcio bioprecipitado. Os resultados obtidos a partir da análise mecânica mostraram que a bioprecipitação de CaCO3 pela bactéria B. subtilis AP91 foi satisfatória, particularmente quando os esporos foram adicionados à água de amassamento, aumentando a resistência à compressão em até 31%. Portanto, conclui-se que a adição de esporos de B. subtilis AP91 na água de amassamento das argamassas induziu a biocimentação, que aumentou a resistência à compressão. A bioprecipitação de carbonato de cálcio pode ter outras consequências benéficas, como o fechamento de poros e fissuras em materiais cimentícios, que poderiam melhorar a durabilidade, embora mais pesquisas neste aspecto ainda sejam necessárias.

Abstract This study aims to evaluate the influence of B. subtilis AP91 spores addition on the mechanical properties of mortars. B. subtilis strain AP91, isolated from rice leaves of the needle variety, which has an early cycle of production, was used at the concentration of 105 spores/mL in mortars with cement-to-sand ratio of 1:3 (by weight) and water-to-cement ratio (w/c) of 0.63. These spores were added in two different ways: in the mixing water and by immersion in a solution containing bacterial spores. Scanning Electron Microscope (SEM) analysis showed crystals with calcium peaks on the EDS, which possibly indicates the presence of bioprecipitated calcium carbonate. The results obtained in the mechanical analysis showed that the bioprecipitation of CaCO3 by B. subtilis strain AP91 was satisfactory, particularly when the spores were added in the mixing water, increasing the compressive strength up to 31%. Thus, it was concluded that the addition of B. subtilis AP91 spores in the mixing water of cement mortars induced biocementation, which increased the compressive strength. This bioprecipitation of calcium carbonate may very well have other advantageous consequences, such as the closure of pores and cracks in cementitious materials that could improve durability properties, although more research is still needed on this matter.

The author's purpose in the present paper is to explore core psychoanalytic concepts that lend support to clinical practice for the members of the International Association of Psychoanalysis of Couple and Family (AIPPF). To achieve this goal the authors have developed a tool that allows to collect information (self-administered questionnaire), briefly presented. The questionnaire requests each member to sort out important concepts in the five following areas: individual psychoanalysis, intersubjective psychoanalysis, group psychoanalysis, family psychoanalysis, couple psychoanalysis, as well as to outline these concepts on three levels: theory, clinic, practice and technique. The sample obtained corresponds to 22 responses which the authors discuss and analyze in detail. In their conclusions, the authors draw attention to the fact that different theoretical orientations are present in couple and family therapy and that the responses to the questionnaire were pondered and on occasion are original and manifest current notions. It can also be observed that current change in family configurations has marked the standpoint concerning certain clinical aspects and links. The authors conclude by highlighting the value of this work to develop new research on more specific aspects, among which several subjected to a more refined approach in recent studies in the institution are mentioned.

En este trabajo los autores se proponen explorar qué conceptos psicoanalíticos centrales que hacen de soporte de la práctica clínica para los miembros de la Asociación Internacional de Psicoanálisis de Pareja y Familia (AIPPF). Para ello los autores han desarrollado un instrumento que permite recolectar la información (cuestionario autoadministrado), que exponen brevemente. En el cuestionario se le solicita a cada miembro que mencione los conceptos de importancia en cinco terrenos: psicoanálisis individual, psicoanálisis intersubjetivo, psicoanálisis de grupo, psicoanálisis de familia, psicoanálisis de pareja, y que especifique dichos conceptos en tres niveles: el de la teoría, el de la clínica, el de la práctica y técnica. La muestra obtenida corresponde a 22 respuestas, que los autores comentan y analizan en detalle. En sus conclusiones, los autores destacan que, respecto de la terapia de pareja y familia, están presentes diferentes orientaciones teóricas, que las respuestas al cuestionario han sido meditadas, y que en ocasiones resultan originales y con un aire de modernidad. También se observa que el cambio en las configuraciones familiares en la actualidad ha dejado una marca en los modos de pensar algunos aspectos de la clínica y de los vínculos. Los autores terminan el trabajo destacando la utilidad de este trabajo para desarrollar nuevas investigaciones sobre aspectos más puntuales, entre los cuales mencionan varios que están siendo objeto de un enfoque más refinado en estudios recientes en la institución.

The results of a study on nematode fauna occurring in wild iguanas (Iguana iguana) from Brazilian Northeast (Alagoas and Maranhão) and Central-west (Goiás and Mato Grosso) areas were presented. Six adult iguanas, three males and three females, were necropsied and the digestive system removed to examination. All the iguana specimens were heavily parasitized. The helminths diagnosed were: Ozolaimus cirratus in the cecum and colon of five iguanas; Ozolaimus megatyphlon in cecum, colon and rectum of three iguanas; and Alaeuris vogelsangi in the small intestine, cecum, colon and rectum of five animals. Two larvae of Ozolaimus sp. were recovered from the pyloric region of the stomach of one iguana. The three diagnosed species of nematodes were reported for the first time in the Brazilian Central-West region.

Descreveu-se o sistema reprodutor feminino em três espécies de mico-leão Leontopithecus (Lesson 1840), cativos: L. rosalia, L. chrysopygus e L. chrysomelas. A vulva está delimitada pelos lábios vulvares menores e com clitóris conspícuo. A superfície do períneo urogenital apresenta elevações papilares mais concentradas nos lábios vulvares, conferindo-lhe aspecto rugoso. O vestíbulo vaginal constitui um tubo muscular de parede espessa que se estende da rima da vulva até o óstio da vagina. A vagina é um tubo muscular alongado e achatado dorsoventralmente, que comunica o vestíbulo vaginal ao colo uterino. O útero piriforme está localizado na porção caudal da cavidade abdominal. Craniolateralmente abrem-se tubas uterinas convolutas e ovários grosseiramente fusiformes de superfície lisa.

It is described the female genital tract of three species of lion tamarin: Leontopithecus rosalia, L. chrysopygus, and L. chrysomelas. Fifteen animals were selected from the Museum of the Center of Primatology of Rio de Janeiro - CPRJ/FEEMA. The vulva is delimited by the labia and has a conspicuous clitoris. The surface of the urogenital perineum has papillary elevations more concentrated in the labia, which results in a rough aspect. The vestibule is a thick-walled muscular tube, extending from the pudendal cleft to the vaginal orifice. The vagina is an elongated and flat muscular tube, which communicates dorsoventrally the vestibulum and the cervix of uterus. The pyriform uterus is located in the caudal portion of the abdominal cavity. Craniolaterally, the convolute uterine tubes open, enveloping the ovaries, which are roughly fusiform with a smooth surface.

For the first time, it was identified a mite in a three-year-old male ostrich that had lost feathers and showed skin irritation. The animal belonged to a flock of 50 birds, located in Baixada Fluminense, in Rio de Janeiro State. After they were fixed in 70% alcohol, clarifyed in lactophenol and mounted in Canada balsam, the mites were identified in the laboratory. They belonged to the Pterolichidae family and Struthioperolichus sculpturatus species (Hirst). The ostrich was treated by ivermectin in dose of 200µg/kg of body weight, with recovery and disappearance of the clinical symptoms. The occurrence of mite infestation by the described species in ostrich should be monitored by professionals and farmers, as they cause fall of feathers and economic losses.

This paper presents the architecture and the VHDL design of the integer Two-Dimensional Discrete Cosine Transform (2-D DCT) used in the H.264/AVC codecs. The forward and inverse 2-D DCT architectures were designed and their synthesis results mapped to Altera FPGAs are presented. The 2-D DCT calculation is performed by exploring the separability property, in such way, each 2-D DCT architecture is divided in two 1-D DCT calculations that are joined through a transpose buffer. The 1-D DCT transforms implemented and herein described are multiplierless, hence optimized shift-add operations are used. The architectures have a dedicated pipeline, optimized to process one input data per clock cycle. These architectures are able to cope with H.264/AVC encoder or decoder requirements targeting High Definition Digital Television (HDTV), with 1920x1080 pixel/frame at 30 frames per second.

In this work we used the Photoacoustic Spectroscopy (PAS) to evaluate the crosslinking of the copolymer from ethylene vinyl trimethoxysilane (EVS) and the grafted vinyl trimethoxysilane (VTS) on low density polyethylene (LDPE). PAS is used for sounding the overtone bands and stretching frequencies combinations of the groupings -Si-OH, =CH2, -CH3 and -CH2 -CH3, in the near and medium infrared range. The samples were typically prepared with 3%, 5% and 7% of catalyst and crosslinked in the temperatures of 70, 80 and 90ºC. Using the overtone bands of -OH groups the PAS shows the optimum combination, pointing a better crosslinking effect for 80ºC and in the range 5% to 7% of catalyst, typically.
