Design optimization of cruciform specimens for biaxial fatigue loading
Baptista, Ricardo; Cláudio, Ricardo; Reis, L.; Guelho, I.; Freitas, M.; Madeira, J. F. A.Com o apoio RAADRI. ; In order to correctly assess the biaxial fatigue material properties one must experimentally test different load conditions and stress levels. With the rise of new in-plane biaxial fatigue testing machines, using smaller and more efficient electrical motors, instead of the conventional hydraulic machines, it is necessary to reduce the specimen size and to ensure that the specimen geometry...

Claudio Ricardo de OliveiraINTRODUCTION: The incisional hernia (IH) is one of the most frequent complications after laparotomy, causing high rates of re-operations. Advances in suture material, in the guidelines for incisions, in the techniques of closure and use of dentures (screens), have failed in the elimination of this surgical complication. In this context, advances in the understanding of biological and structural changes of colla...

Claudio Ricardo AugustoThe objective of this study was to investigate the possibility of the appropriation of the concept of first degree functions to students of 3 rd grader of high school, from an intervention of education subsidized by technological tools. With this objective in mind, the study intends to answer the following question of research: What are the contributions to the education of relative concepts of first degree fun...
Calibration of a capacitance probe in a Paleudult
Silva,Cláudio Ricardo da; Andrade Júnior,Aderson Soares de; Alves Júnior,José; Souza,Antonio Barros de; Melo,Francisco de BritoThe use of capacitance sensors is one of the methods used to quantitatively measure soil water contents (theta, m³ m-3). Sensors provide readings at desired depths and time intervals. A capacitance probe (Diviner 2000) was calibrated for a Rhodic Paleudult from the Piaui State, Brazil. Six access tubes were installed in a 5 × 2 m grid arrangement. Three moisture levels (saturated, moist and dry) were used...
An application of management methodologies to a continous production manufactur...
Claudio Ricardo Monteiro PintoAtualmente o aumento da competitividade industrial e da concorrência, está gerando uma busca constante de produtos inovadores e de baixo custo. Alguns seguimentos industriais também tem sentido o poder das commodities , onde grande parte dos custos envolvidos nos processos, principalmente matérias-primas, não são de controle da empresa dificultando e reduzindo a sua margem de atuação frente a concorrência. Exis...
Water relations and photosynthesis as criteria for adequate irrigation manageme...
Silva,Cláudio Ricardo da; Folegatti,Marcos Vinícius; Silva,Tonny José Araújo da; Alves Júnior,José; Souza,Claudinei Fonseca; Ribeiro,Rafael VasconcelosIrrigation scheduling based on soil moisture status is one of the most useful methods because of its practicality and low cost. The effects of available soil water depletion on evapotranspiration (ETc), transpiration (E), leaf water potential at predawn (psiP) and midday (psiM), stomatal conductance (gs) and net CO2 assimilation (A) in lime 'Tahiti' trees (Citrus latifolia) were evaluated to improve irrigation ...

Cláudio Ricardo da SilvaWater and physiologic relations in acid lime trees under water stress were studied with the following purposes: (a) to verify the seasonal effect of evapotranspiration and the crop coefficient in non-stressed trees by weighing lysimeter; (b) to determine the critical soil water depletion for evapotranspiration, gas exchange as well as the leaf water potential during a stage of growing of the trees and (c) to de...
The sexual behaviour of Panstrongylus megistus (Hemiptera: Reduviidae): an expe...
Pires,Herton Helder Rocha; Lorenzo,Marcelo Gustavo; Lazzari,Claudio Ricardo; Diotaiuti,Liléia; Manrique,GabrielThe factors affecting the sexual behaviour of Panstrongylus megistus were studied under laboratory conditions. A general description of mating behaviour is presented for this species. The effect of the time elapsed after the first imaginal feeding on the mating frequency, the motivation of males to mate and the rejection behaviour by females, were analyzed. We also determined the number of copulas accepted by f...
Corpos na arena: um olhar sobre prática das artes marciais combinadas
Claudio Ricardo Freitas NunesEsta pesquisa de cunho etnográfico, realizada em três academias de lutas, localizadas na cidade de Porto Alegre-RS, no período de dezembro/02 a julho/04, registrou o envolvimento de sujeitos na prática de uma luta, em que são combinados diversos golpes de distintas artes marciais com técnicas de boxe, denominada de Mixed Martial Arts. A partir do referencial teórico que compreende o corpo como uma construção hi...
Temporal change of the aggregation response in Triatoma infestans
Figueiras,Alicia Nieves Lorenzo; Lazzari,Claudio RicardoAdults and larvae of Triatoma infestans spend daylight hours assembled in shaded places. An assembling factor has been demonstrated in the excrement of this species. We analysed different aspects of the dynamics of the response of bugs. Recently fed insects do not aggregate around faeces. They start to show a significant assembling response from the 8th hour after feeding onwards. Just deposited faeces do not e...
