15. Influência da composição de substrato do recife na atividade e distribuição de peixes zoobentívoros no arquipélago de Fernando de Noronha, Pernambuco / The influence of substratum composition on the activity and distribution of benthic carnivorous reef fishes of the Fernando de Noronha Archipelago
Reefs provide shelter and food for several fish species and, thus, there may be a correlation between the abundance and behaviour of fishes and the reef bottom composition-Physical factors, such as water movement and depth, may also have a profound impact in species distribuiton and activity on reefs. Here, the possible relationship between the distribution

16. Propagación in vitro de plantas adultas de Vaccinium meridionale (Ericaceae)
Using stem apex as primary explants, a micropropagation protocol of Vaccinium meridionale was established. During establishment phase the effect of the MS/3, WPM, AND and Kyte media, supplemented with 2-iP plus IAA or BA plus IAA was studied. During microshoot proliferation the effect of MS/3 liquid, solid and double phase (the liquid phase in a solidified p

17. Crecimiento inicial de Palo de Rosa (Aniba rosaeodora Ducke) en distintos ambientes de fertilidad
Studies of nutritional requirements are of great importance for identifying the most important nutrients in physiologic development and seedling growth. A greenhouse pot experiment was conducted at INPA to evaluate the mineral nutritional demands and the effects of macronutrient omission in the plant growth of Aniba rosaeodora Ducke. The following treatments

18. Substratum quality indicators for revegetated areas monitoring: study directed to the sand mining. / Indicadores da qualidade do substrato para monitoramento de áreas revegetadas: estudo dirigido à mineração de areia.
Mining is an agent of significant changes in soil properties. Successful land rehabilitation depends on restoring those characteristics in natural soils or establishing a suitable substratum for plant growth using available materials such as waste rock or mineral tailings. A process for monitoring the quality of the substratum in mine-affected areas was deve

21. Effect of denture cleansers on Candida species biofilms formed on the surface of differents materiais used in dentures base / Efeito de limpadores quimicos sobre biofilmes de Candida formados sobre a superficie de materiais para base de proteses removiveis
Candida denture biofilm is considered the the primary aetiological agent for the development of oral candidosis, which is the most common fungal oral infection in humans. Although, for patients with limited motor capacity, chemical cleansing with immersion in denture cleansers has been shown to be effective in controlling Candida biofilm accumulation, limite

22. Obtenção de células de Salmonella resistentes a desidratação para o preparo de material de referência / Attainment of resistant cells of Salmonella the dehydration for the preparation of material of reference
Programs of control and management of the quality in laboratories, the necessity of standardization of the analysis methods and repeatability of the experimental data have stimulated the increase of the use of Reference Material (RM) in the microbiological analyses. Considering that the stages of preparation and storage of the MR are stress processes that ca

23. Produção de minitubérculos de batata-semente básica em vaso e hidroponia, em função de doses de nitrogênio / Producing minitubercules of the basic potato-seed in either pot and hydroponics as function of nitrogen doses
New propagation techniques have been proposed for production of the basic potato-seed (Solanum tuberosum L.), such as the propagation by sprout, hydroponics and planting in pots containing substratum. Those new techniques represent an important progress in the potato productive process. In the available literature, there are few studies relating the effect o

24. Association of hypotalamic POMC, NPY and IRS2 with feeding behavior in norma and overweight Wistar rats / Associação do PMOC, NPY e IRS2 hipotalâmicos com padrões de comportamento alimentar em ratos wistar normais e sobrepeso
The feeding behavior of a specie is determined by a group of phylogenetic, ontogenetic, and epigenetic features, and regulated by internal and external factors to the organism. The natural phenomena that govern life in our planet are mainly periodic, and the food stocks is not an exception. Each harvest is followed by a time between harvests, and this rhythm
