1. Temporal progress and spatial patterns of quiescent diseases in guava influenced by sanitation practices
ABSTRACT: Postharvest diseases are a major problem in guava crops as the symptoms normally appear during fruit ripening. This study aimed to detect and characterize the temporal dynamics and spatial patterns of the most important guava diseases in orchards with and without removal of crop residues as a sanitation practice. The experiment was conducted in an

2. Genetic variability of Bipolaris sorokiniana isolates using URP-PCR
Spot blotch disease, caused by Bipolaris sorokiniana, is one of the major diseases of wheat and is responsible for large losses of wheat crops worldwide. We used polymerase chain reaction (PCR) with universal rice primers (URP) for molecular characterization of 60 monosporic B. sorokiniana isolates from Brazil and other countries, and evaluated the diversity

3. Genotyping and drug resistance patterns of Mycobacterium tuberculosis strains observed in a tuberculosis high-burden municipality in Northeast, Brazil
OBJECTIVES: This study has used a combination of clinical information, spoligotyping, and georeferencing system to elucidate the genetic diversity of the Mycobacterium tuberculosis isolates circulating in a TB-prevalent municipality of Northeast Brazil. METHODS: A total of 115 M. tuberculosis strains were isolated from pulmonary tuberculosis patients from Ja

4. Optimized microlens-array geometry for Hartmann-Shack wavefront sensor: design, fabrication and test
The Hartmann-Shack (H-S) wavefront sensor is now deployed in many different fields, from astronomy to industrial inspection, where the quality of optical media or components can be measured by the distortions (wavefront aberrations) they impart on a wavefront transmitted or reflected by them. In ophthalmology, this sensor is a core component of major aberrom

5. Phylogenetic diagnosis and expanded description of the genus Mazarunia Kullander, 1990 (Teleostei: Cichlidae) from the upper Mazaruni River, Guyana, with description of two new species
We expand the description of the genus Mazarunia Kullander, 1990, explore morphological diagnostic characters for the genus and for its sister-group relationship with Guianacara Kullander & Nijssen, 1989 in a phylogenetic context, expand the description of M. mazarunii and describe two new species. Mazarunia can be diagnosed by the combination of numerous an

6. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns

7. Characteristics of masticatory muscles in children with unilateral posterior crossbite
The aim of this study was to detect possible differences in the EMG (electromiography) activity, chewing rate (CR), cycle duration (CD) and preferred chewing side (PCS) between children with and without unilateral posterior crossbite. Thirty-seven children aged from 7 to 10 years were selected from the clinic of the Department of Pediatric Dentistry, Piracic

8. Análise proteômica das respostas agudas e crônicas ao exercício de endurance no músculo esquelético de ratos / Proteomic investigation of the acute and chronic changes in rat skeletal muscle in reseponse to endurence exercise
In the present work the acute and chronic changes in rat skeletal muscle in response to endurance exercise were investigated by proteomic analysis. The results are presented in two separated studies. In the first study gastrocnemius muscle were sampled from control non exercised animals and from animals exercised to exhaustion in an incremental manner in a t

10. Desenvolvimento de métodos de detecção precoce de infecções quiescentes de Colletotrichum spp. em mamão / Development of early detections methods of quiescent infections of Colletotrichum spp. on papaya fruits
The objetives of this study were to evaluate the methods, maturation age, temperature effect, distribution and sample size to detect quiescent infection of Colletotrichum spp. (Glomerella cingulata) on papaya fruits. At first, different methods to detect quiescent infections on immature fruits were assessed: sodium hipoclorite (1,5%), paraquat (6 ml/L a.i.),

11. Desenvolvimento de descritores de imagens para reconhecimento de padrões de plantas invasoras (folhas largas e folhas estreitas)
In Brazil, the development of tools for weeds recognition, capable of aiding risk detection and decision making on the fieldwork is still embryonic. This masters thesis presents the development of a pattern recognition system that recognizes weeds and gives the occupation percentage of wide and narrow leaves in an agricultural production system, with digital

12. Oito ciclos de seleÃÃo recorrente visando à resistÃncia à mancha-angular no feijoeiro / Eight cycles of recurrent selection aimed at resistance to angular leaf spot in common bean
This work was carried out with the objective of evaluating both the genetic progress after eight cycles of phenotypical recurrent selection for resistance to angular leaf spot in bean plants and the indirect responses for both productivity and grain types. The base population was obtained from partial diallelic crossing of seven carioca-type grain lines (Car
