1. Old tools as new support for on farm conservation of different types of maize
ABSTRACT: A germplasm collection should represent the diversity of the target species and the gene pools associated with it. However, it is critical to establish collection plans which ensure such representativeness. At times it is difficult to identify the best strategy for collecting domesticated species that are conserved in situ/on farm, since, in genera

3. Influência da temperatura de molde associada com o uso de fibra de vidro nas propriedades mecânicas e térmicas do nanocompósito (PA6/FV/MMT)
ABSTRACT This work describes the second of a series of studies of the effects of injection molding conditions on the mechanical and thermal properties of Polyamide 6/Glass Fiber/Montmorillonite (PA6/GF/MMT) composites and was motivated by the lack of information about how the processing variables influence on the properties of three-phase composites containi

4. Effect of cantilever length and alloy framework on the stress distribution in peri-implant area of cantilevered implant-supported fixed partial dentures
ABSTRACT Because many mechanical variables are present in the oral cavity, the proper load transfer between the prosthesis and the bone is important for treatment planning and for the longevity of the implant-supported fixed partial denture. Objectives To verify the stress generated on the peri-implant area of cantilevered implant-supported fixed partial d

5. Assessment of cephalometric characteristics in the elderly
This cross-sectional study aimed at assessing the cephalometric characteristics in the elderly, taking into account differences between genders, age ranges, ethnic groups and dental aspects. The sample consisted of 250 elderly subjects of both genders (163 female, mean age: 68 yr.; 87 male: 70.4 yr.). Conventional lateral cephalograms for cephalometric analy

6. Modelo de tomada de decisões em disciplinas vinculadas às ciências da enfermagem: revisando as bases conceituais para formação de novos perfis profissionais. / Decision-making model in technical subjects of nursing: Revising the conceptual basis for the building of new professional profiles.
This research has as an object of study the syllabus of courses related to Nursing Sciences which are part of the curriculum of undergraduate courses and aims to understand how the process of decision making has been aired in these subjects with a focus on the training of nurses. The research is justified by the fact that there is a lack of information about

7. Caracterização da displasia fibrosa em imagens de tomografia computadorizada helicoidal empregando a análise da lacunaridade / Characterization of fibrous dysplasia in helical computed tomography images employing the analysis of lacunarity
Fibrous dysplasia is an alteration of development characterized by replacing normal bone for dense connective tissue and immature trabecular bones, typically found in teenagers and young adults. Genetic modification which involves alpha-Gs protein appears to be the basis of the process. The exact incidence and prevalence are difficult to be established, but

9. Optimization of controlled release primaquine diphosphate tablets / Otimização da liberação de difosfato de primaquina em comprimidos de liberação controlada
The objective of the present work was to produce primaquine diphosphate controlled release tablets based on hydrophilic polymers and use the mixture statistical experimental design (DOE) to optimize drug release. In selecting the components of the formulations, differential scanning calorimetry (DSC) were carried out to verify the compatibility between drug/

10. Desenvolvimento de métodos analíticos para determinação de As, Cd, Ni e Pb em batata e em mandioca produzidas em regiões mineiras empregando espectrometria de absorção atômica em forno de grafite
In this dissertation methods to determine arsenic, lead, nickel and cadmium in food are described, more precisely in potato and manioc, grown in the Minas Gerais state territory in Brazil, which is also known as "Quadrilátero Ferrífero" (an area in the state where mining for ore and other metals is a current major economic activity). In the methods propose

11. Study of the parameters for microhardness test on dentin and enamel bovines, composite resin and amalgam / Estudo de parâmetros para ensaios de microdureza em amálgama de prata, resina composta, dentina e esmalte bovinos
The hardness is a mechanical property utilized to compare restorative materials such as biological tissue and can be defined as the resistance of material for a permanent impression and a number related to the applied force and the surface area. As each material has its own mechanical characteristic, for this study utilized two materials: amalgam and composi

12. Evaluation of simulated bone lesion in the head of the jaw by using multislice computed tomography / Avaliação de lesões ósseas simuladas na cabeça da mandíbula pela tomografia computadorizada multislice
There are limitations for image acquisition using conventional radiography of the temporomandibular joint (ATM) region. Computerized tomography (CT) scan is a better option due to its higher specificity and sensitivity for diagnosis, surgical planning and treatment of bone injuries. The purpose of this study is to evaluate simulated bone injuries of the head
