Densidades e manejo químico da tiririca na produtividade de cana-de-açúcar

Em dois experimentos instalados e conduzidos a campo, foram avaliados os efeitos de densidades da tiririca e do seu controle químico na produtividade da cana-de-açúcar (var. SP 86042). No primeiro, três densidades foram estudadas: baixa (58 a 246), média (318 a 773) e alta (675 a 1.198 manifestações epígeas m-2). As reduções na produção foram de 13,5, 29,3 e 45,2% em relação à testemunha sem tiririca, respectivamente. No segundo experimento, foram testados os herbicidas sulfentrazone (0,8 kg ha-1), imazapic (0,105 kg ha-1) e flazasulfuron (0,150 kg ha-1), em pré-emergência, além da mistura de trifloxysulfuron-sodium + ametryne e Agral® (1,5 kg ha-1 + 0,20%), halosulfuron + Aterbane® (0,105 kg ha-1 + 0,25%) e flazasulfuron + Aterbane® (0,150 kg ha-1 + 0,25%), em pós emergência. Nesta área, a variação de densidade foi de 66 a 154 plantas m-2. Aos 90 dias após o plantio (DAP), as porcentagens de controle foram de 79,6; 70,6; 30,3; 84,8; 89,1; e 61,1%, respectivamente, para os herbicidas testados. A redução na produtividade foi de 16,4% entre as testemunhas infestada e capinada e de 11,9 e 6,0% onde se aplicou o flazasulfuron em pós e pré-emergência, respectivamente.

Sorologia Anti PGL-1 e risco de ocorrência de hanseníase em área de alta endemicidade do Estado de São Paulo: quatro anos de seguimento

Os testes sorológicos para diagnóstico de hanseníase, usando o glicolipídeo-fenólico-1 (PGL-1), considerado antígeno específico do M. leprae, têm aberto algumas possibilidades de estudo do comportamento epidemiológico desta doença. Algumas questões, como tempo de latência da doença, infecção subclínica e importância do contato intra-domiciliar (contatos) no controle da endemia, puderam ser melhor analisadas usando este instrumental. Este estudo teve por objetivo verificar a existência de associação entre a situação sorológica e a ocorrência de hanseníase. Foram seguidas, durante 4 anos, 6.520 pessoas com idade igual ou superior a 5 anos, submetidas no início do seguimento ao teste sorológico Anti PGL-1, pertencentes ao universo de 7.416 habitantes da área urbana de um município paulista caracterizado por elevada endemicidade de hanseníase. Foi identificado um grupo de 590 indivíduos soropositivos (9,0 %). Foram diagnosticados, no período, 82 casos novos de hanseníase, 26 no grupo de soropositivos (441 casos novos/10.000 indivíduos) e 48 no de soronegativos (81/10.000). Entre os que não fizeram sorologia, surgiram 8 casos novos (89/10.000). Procurou-se controlar, na análise, a condição de contato, dado que a taxa de soropositividade padronizada por idade e sexo era de 9,61% no grupo de contatos e 7,65% no de não-contatos. Tomando-se os não-contatos soronegativos como o grupo de não expostos, foram calculados os riscos relativos de adoecimento no período, a partir das taxas de detecção padronizadas por idade, resultando no seguinte: os contatos ID soropositivos apresentaram a taxa de 1.704/10.000, 27 vezes maior que a dos não-expostos, igual a 63/10.000; os não-contatos soropositivos e os contatos soronegativos apresentaram taxas, respectivamente, de 274 e 198/10.000, ambas maiores que as dos não-expostos e iguais entre si. A soropositividade associou-se à elevação de 8,6 vezes do risco de hanseníase entre os contatos e de 4,4 entre os não-contatos. Na situação epidemiológica estudada, caracterizada por elevada endemicidade de hanseníase, 50% dos casos novos surgiram entre os não-contatos soronegativos, ou seja, sem fonte de infecção conhecida. Portanto, o teste anti-PGL-1 usado revela-se, na prática, de pouca aplicabilidade. Resta estudar ainda o comportamento da sorologia anti-PGL-1 em áreas de média e baixa endemicidade para que se possa tirar conclusões mais consubstanciadas sobre sua utilidade no controle da endemia. Recomenda-se o aprofundamento das pesquisas sorológicas e de outras que aprimorem o diagnóstico precoce da infecção subclínica, inclusive para detecção de formas paucibacilares, para se ampliar as possibilidades de influir no controle endêmico.

Ophiuroidea das regiões Antártica e Subantártica: 2. Variação em Gorgonocephalus chilensis ( Philippi) (Echinodermata, Ophiuroidea, Gorgonocephalidae)

Foram examinados 198 exemplares de Gorgonocephalus chilensis das regiões antártica e subantartica, tendo-se em vista a variação de caracteres morfológicos externos. Foi constatada uma grande variação nas características morfológicas externas, que parece independer de localização geográfica.

Brachytherapy using gold-198 foils in treatment of mouth tumors: case report

The authors presents a clinical case treated with brachytherapy performed with special mold of gold-198 disc, with the purpose of evaluating the distribution of radiation dose, the viability of manufacturing the radioactivity prosthesis and its operational cost. In despite of being only one case, we can conclude that the prosthesis with gold-198 foils can be manufactured in acrylic with thickness thinner than those ones with cylinder of cesium-137, resulting lower operational costs, besides permitting better distribution of radiation dose on the lesion.

Esthetic influence of negative space in the buccal corridor during smiling

The purpose of this study was to measure and verify the esthetic influence of the bilateral spaces between maxillary teeth and lip corners, called negative space (NS), during smile. The sample was comprised of 60 smile photographs obtained from 60 individuals (30 men and 30 women) aged 18 to 25 years old. Two orthodontists and two lay people evaluated these pictures regarding esthetics by a visual analogue scale. In each picture, the right and left NS were measured in millimeters and in proportion to the smile width (SW). Data were analyzed for statistical significance (P = .05). The mean NS of the sample was 6.68 ± 1.99 mm, and the NS proportion in relation to the SW was 9.6 ± 2.56%, for both sides of the arch. No significant asymmetries were observed between the right and left sides. The NS was significantly larger in men than in women when measured in millimeters (P = .028) (7.08 ± 2.24 mm in men vs 6.28 ± 1.62 mm in women), but the NS proportion to the SW was similar (9.94 ± 2.24% in men vs 9.26 ± 1.61% in women). When the 12 individuals with the smallest NS in proportion to SW were compared with the 12 individuals with the largest NS in proportion to SW, there was no statistical difference regarding the esthetic evaluation (P = .11). It was concluded that the NS did not influence the esthetic evaluation of smile photographs in the sample in this study, for both orthodontists and lay people. © 2006 by The EH Angle Education and Research Foundation, Inc.

A semi-automatic method for indirect orientation of aerial images using ground control lines extracted from airborne laser scanner data

This paper presents a method for indirect orientation of aerial images using ground control lines extracted from airborne Laser system (ALS) data. This data integration strategy has shown good potential in the automation of photogrammetric tasks, including the indirect orientation of images. The most important characteristic of the proposed approach is that the exterior orientation parameters (EOP) of a single or multiple images can be automatically computed with a space resection procedure from data derived from different sensors. The suggested method works as follows. Firstly, the straight lines are automatically extracted in the digital aerial image (s) and in the intensity image derived from an ALS data-set (S). Then, correspondence between s and S is automatically determined. A line-based coplanarity model that establishes the relationship between straight lines in the object and in the image space is used to estimate the EOP with the iterated extended Kalman filtering (IEKF). Implementation and testing of the method have employed data from different sensors. Experiments were conducted to assess the proposed method and the results obtained showed that the estimation of the EOP is function of ALS positional accuracy.

Brucella ovis REO 198 natural and experimental infection in Santa Inês rams from Brazil

B. ovis pathogenicity was evaluated in experimentally inoculated and naturally infected rams. Ten animals were submitted to simultaneous conjunctival and intrapreputial inoculation with 2x109 CFU/ mL of B. ovis REO 198. After that, animals underwent physical examination and blood samples were collected for serology every week. Positive serology results started to be observed in the 3rd week, with fluctuations in titers. Clinical changes began in the 5th week after inoculation and were associated with positive serology in the acute phase of the disease. Presence of B. ovis in semen and urine culture was intermittent. Three non-inoculated animals showed natural infection. B. ovis was shed twice in semen of one serology-negative animal. The study underscored the pathogenic characteristics of B. ovis REO 198 in Santa Inês rams, as well as the importance of animals as potential sources of infection.

Les Salles de Ressouces Multifonctionnelles: un recous pour les écoles inclusives au Brésil

In the 90s, the Brazilian Secretariat of the Special Education Department has expanded the democratization of education and pupils’ access to schooling, by redefi ning the operation of special education services. With this inclusion policy, the education system has been restructured. An important action, conducted during the period de 2005 to 2010, was to propose, deploy and implement Multifunctional Resources Rooms (Sala de recursos multifuncionais, or SRM), from two different types (type I and II). The challenge was to promote educational inclusion, in a program entitled Inclusive Education: the right to diversity. In a seek for new identity of teacher training and professional practice in special education, the great educational innovation is to better articulate the work of “ordinary“ and specialized teachers, via the SRM, and to develop collective and participatory actions between common spaces and support spaces. In this context, the school and the family represent an important source of partnership.

Análise retrospectiva de 61 casos de paracoccidioidomicose diagnosticados na Faculdade de Odontologia de Araçatuba/ UNESP

Paracoccidioidomycosis is a systemic mycosis which requires prolonged treatment. It is highest prevalence in Latin America, with different endemic areas in Brazil. In this study the aim was to characterize clients suffering from mucocutaneous paracoccidioidomycosis by analysis of histopathological examinations of 61 adult patients diagnosed with mucocutaneous paracoccidioidomycosis treated at the Dental School of Araçatuba, from January 1989 to December 2004. It was observed that the disease occurred in 91.81% (56) men and 8.19% (5) women, more prevalent (78.68%) in whites, aged 40 to 59 years (62.9%) and the profession linked to agriculture in 17 patients (27.86%). All patients had oral manifestations, in multiple sites, but it was most prevalent in the oral mucosa (31.42%) and alveolar ridge (17.14%). The dentist as an integral member of the health services, must know the clinical manifestations of paracoccidioidomycosis to achieve early diagnosis and thereby to improve the quality of life of patients.
