13. Agricultura de base ecológica em sistemas urbanos: potencialidades, limitações e experiências.
ABSTRACT: Urban agriculture conducted with ecological principles is an alternative to produce healthy food, but it demands planning and suitable technologies. This ecological approach must be based on crop diversity, organnic or mineral fertilizers from natural origin and control of pests and diseases by non-toxic means. Cultivation of different species is t

17. INFLUÊNCIA DO CONTEÚDO DE MATÉRIA SECA E REGULAGENS DE UMA COLHEDORA DE FORRAGEM NOS TAMANHOS DE FRAGMENTOS E NA DENSIDADE DA SILAGEM DE PLANTA INTEIRA DE DOIS HÍBRIDOS DE MILHO (Zea mays L.) 2008 / DRY MATTER CONTENT AND FORAGE HARVESTER SETUP INFLUENCES IN THE PARTICLE SIZE AND BULK DENSITY (Zea mays L.) FOR WHOLE PLANT SILAGE OF TWO HIBRIDS OF CORN
In Brazil, the best dairy farm efficiency levels are obtained in the cities of Castro and Carambeí, State of Paraná. This efficiency was reached due to the animal genetics and the feed management, where the corn whole plant silage has been wide used. To the highest profit of the silage, some stages must be considered. The main stages are the selection of t

18. Effect of additives on feed quality and nutritional value of sugarcane silage. / Qualidade da silagem de cana-de-aÃÃcar elaborada com diferentes aditivos.
The objective of this research was to evaluate the effects of the use of additives on the quality and nutritional value of the sugarcane silage. Sugarcane variety RB-72454, at 18 months of regrowth, was stored for 180 days in experimental concrete silos (500 kg capacity). Treatments were expressed by additives amounts added to sugarcane silage at ensiling (b

19. Cultivares e Ãpocas de corte no rendimento e composiÃÃo mineral do feno de soja [Glycine max (L.) Merrill] / Cultivate and cutting periods in the yield and mineral composition of the soybeanâs hay [Glycine max (L) Merrill]
The annual soybean has been detached among other leguminous plants as being rich in nutrients. Soybeans may be used to feed animals as grain, bran, roller, silage, green plant, as well as hay harvested during the vegetative, flowering, or fruit stages. With the objective of verifying the influence of the cutting periods on the yield and mineral composition o

22. Simulação da cinetica do crescimento de pontos quanticos semicondutores em vidros
The growth kinetics of pontos quânticos (QD) in a vitreous matrix is important because its linear and non linear optical properties depends on their sizes and dispersion. QD s are fabricated by melting the semiconductors elements together with the vitreous matrix. After melting, the glass is submitted to a thermal treatment to lower temperatures, (500- 600�

24. Limitations of lysine-iron-cystine-neutral red broth in the presumptive identification of Salmonella.
Lysine-iron-cystine-neutral red broth performed satisfactorily in the presumptive identification of Salmonella in preenriched food and animal feed samples enriched in tetrathionate-brilliant green broth. Homologous results from selenite-cystine enrichment broths yielded unacceptably high numbers of false negative reactions.
