13. Limiting factors in cost systems implementation in medium size enterprises: a case study / Fatores limitantes em implementações de sistemas de custos em empresas de porte médio: um estudo de caso
In the current companies competitive environment, it is necessary that they use tools to keep their continuity. The Strategic Cost Management is one of these devices and, therefore, a cost system is necessary to guide the managers decision of an organization, which starts to demand faster more elaborated information. These systems implementation, which are m

14. Envelhecimento acelerado e avaliação da qualidade fisiológica de sementes de trigo acondicionadas em diferentes embalagens e armazenadas em ambiente natural em Ibitirama-ES
The wheat is a grassy one, whose seeds present high germination. These works had had as objective to study the germination, the vigor and the storage of wheat seeds. In the study of the accelerated aging and experiment casualizado was lead in the completely randomized design, with four replications of 25 seeds. The temperatures (41, 43, 45C) and the adequate

15. A turbulent bed contactor: energetic efficiency for particle collection
Particle collection experiments were conducted in a fluidizing irrigated bed to evaluate the performance of mobile packings: 38 x 50 mm plain oblate spheroids 38 mm ID plain spheres and alternative perforated spheres with a 38 mm ID and 10% and 25% free areas were used as fluidizing media in a 0.264 m diameter and 1.20 m high turbulent bed contactor (TBC).

16. From binary codes to lattices and spherical codes / De codigos binarios a reticulados e codigos esfericos
In this work it is presented through examples a connection between inary codes, lattices and spherical codes. A brief introduction to coding theory, properties and examples is included in the first chapter. In Chapter 2 lattices are approached with focus on the quotient of lattices, graphs on flat tori and connections with circulant graphs. An introduction t

17. Changes in the chemical and physico-chemical characteristics of the guava juice (Psidium guajava L.) during processing. / ALTERAÃÃES DAS CARACTERÃSTICAS QUÃMICAS E FÃSICO-QUÃMICAS DO SUCO DE GOIABA (Psidium guajava L.) DURANTE O PROCESSAMENTO
Fruit juices are important vitamin sources, mineral salts, organic acids and fibers, and including in the diet of the population, they can help to keep people healthy. During the stages of juice processing, some modifications in the fruit compounds can happen, affecting its sensorial and nutritional properties. Researches on the effects of processing on the

18. Avaliação da secagem, torrefação e estabilidade da castanha de pequi (Caryocar brasiliense Camb.) / Evaluation of drying, roasting chestnuts, and stability of pequi (Caryocar brasiliense Camb.)
Pequi (Caryocar brasiliense Camb.) possesss in its interior eatable chestnut little explored. In this study it was objectified to evaluate the drying process, toasting and the stability of the chestnut during 180 days in three different packings. Seeds supplied for the Association of Improvement of Fruits of the Open pasture, located in the city of Damianóp

19. Calculation of the longevity of tomato seeds / Equacionamento da longevidade de sementes de tomate
The longevity is the period of time where the seeds are kept viable. Its extremely important for the storage analysis, the forecast of the viability loss of the seeds when comparing with differents storage conditions. The present work had as objective: to equate the initial quality of the seeds (Ki) of tomato in function of the initial tests of germination a

20. Dense packings
Dense packings of granular systems are of fundamental importance in the manufacture of hard ceramics and ultra strong concrete. We generalize the reversible parking lot model to describe polydisperse dynamic packings. The key ingredient lies in the size distribution of grains. In the extreme case of perfect filling of spherical beads (density one), one has A

21. Spherical codes with cyclic symmetries / Codigos esfericos com simetrias ciclicas
Euclidean spherical codes with symmetries are orbits of finite orthogonal matrix groups. These codes are also known as group codes. ln this work, the commutative group codes in even dimensions are viewed on flat tori, which are submanifolds of the sphere. Also, if the matrix group is cyclic, the generated code lies on a knot which wraps around a torus. If th

23. Avaliação fisico-quimica e microbiologica de linguiça Toscana porcionada e armazenada em diferentes embalagens, sob condições em estocagem similares as praticadas em supermercado. / Microbiological and physicist-chemistry evaluation of Toscana sausage stored in different packings in the supermarket.
The re-packaging of food products is a very common procedure in the supermarket, especially in meat products, although the quality and safety of these products can be seriously endangered. Taking into account this situation, the objective of this work was to evaluate the physical, chemical and microbiological quality of Toscana sausage packaged in the superm

24. Novas fases estacionárias à base de sílica para cromatografia líquida de alta eficiência
The present work reviews recent advances in the preparation of new reversed phase packing materials such as sterically protected, bidentate, hybrid organic-inorganic and monolithic phases and phases containing embedded polar groups. The bonding chemistry involved in the preparation of these phases as well as their advantages over conventional C8 and C18 reve
