1. INFLUENCE OF INTERFACIAL FORCES ON THE MIXTURE PREDICTION OF AN ANAEROBIC SEQUENCING BATCH REACTOR (ASBR)
AbstractIn the operation of bioreactors, the fluid movement promotes mixing between sludge and substrate. The dynamics of this system are complex, and the interaction between the phases is difficult to evaluate accurately. In this work, Computational Fluid Dynamics is applied to simulate a pilot-scale anaerobic sequencing batch reactor, using a three-dimensi

2. TRIHALOMETANOS EM ÁGUA POTÁVEL E RISCOS DE CÂNCER: SIMULAÇÃO USANDO POTENCIAL DE INTERAÇÃO E TRANSFORMAÇÕES DE BÄCKLUND
We briefly investigated the well-known correlation of trihalomethanes, present in fresh water, with cancer hazard in humans. A transient alternative method of chemical simulation using Bäcklund Transformations and Quantum Mechanics is presented. Finally, the method was applied to simulate the interaction between Trichloridemethane and Alanine - as well as i

3. Fine-tuning of defensive behaviors in the dorsal periaqueductal gray by atypical neurotransmitters
This paper presents an up-to-date review of the evidence indicating that atypical neurotransmitters such as nitric oxide (NO) and endocannabinoids (eCBs) play an important role in the regulation of aversive responses in the periaqueductal gray (PAG). Among the results supporting this role, several studies have shown that inhibitors of neuronal NO synthase or

4. Novel regulatory SNPs in the promoter region of the TNFRSF18 gene in a Gabonese population
Parasites are accountable for driving diversity within immune gene families. We identified and investigated regulatory single nucleotide polymorphisms (SNPs) in the promoter regions of the tumor necrosis factor receptor superfamily member 18 (TNFRSF18) gene by direct sequencing in a group of male Gabonese individuals exposed to a wide array of parasitic dise

5. Biphasic haustorial differentiation of coffee rust (Hemileia vastatrix race II) associated with defense responses in resistant and susceptible coffee cultivars.
The objective of this study was to assess whether defence responses in coffee (Coffea arabica) were linked to a specific developmental stage of the rust fungus Hemileia vastatrix. Histological observations in compatible and incompatible highyielding Brazilian coffee cultivars showed that the fungus produced ?pioneer? haustoria in adjacent and subsidiary stom

7. Análises moleculares das vias de sinalização de morte celular originadas no retículo endoplasmático / Molecular analyses of cell death pathways signalling originated in the endoplasmic reticulum
Abiotic and biotic stresses are responsible for major losses in agricultural productivity world wise. Therefore, the understanding of mechanisms of plant stress response and adaptation to such conditions should provide the foundation for engineering plant stress tolerance and hence maximizing the yield of crops growing under adverse environmental conditions.

8. Análise da expressão de regiões da proteína Circumsporozoíta de Plasmodium sp. em Aedes aegypti infectado por Plasmodium gallinaceum. / Expression analyses of Plasmodium sp. Circumsporozoite protein regions in Plasmodium gallinaceum infected Aedes aegypti.
Transgenic mosquitoes that impair malaria transmission can be an alternative control but currently an effective line is not available. A better understanding of mosquito interaction with pathogens is very important to improve refractory transgene design. Circumsporozoite protein (CSP) has two conserved domains that could be involved in spz penetration into m

9. NUMERICAL STUDY OF THE INTERACTION BETWEEN A SUPERSONIC JET AND PLANAR SURFACE / ESTUDO NUMÉRICO DA INTERAÇÃO ENTRE UM JATO SUPERSÔNICO E UMA SUPERFÍCIE PLANA
I in this work a study of the interaction between a supersonic jet and a planar surface is presented, with the aim to analyze the behavior of the velocity, pressure and temperature flowfield. This study finds its motivation in the process of thermal spallation of hard rocks, which may result from the interaction between a high pressure and high temperature j

10. InteraÃÃo transitÃria entre transformadores de potencial capacitivos e linhas de transmissÃo: uma contribuiÃÃo para minimizar falhas
Coupling capacitor voltage transformers (CCVT) are widely used in power systems for monitoring, protection relays and control aplications. Failure of this equipment may cause unexpected outages of transmission lines (TL), which may result in severe penalties as imposed by the regulatory agency of the government. This fact requires speeding maintenance proced

11. Numerical analysis of the tunnelling with emphases in the ground-support interaction in shotcrete at early ages / Análise numérica de escavações subterrâneas com ênfase na interação entre o maçiço e o suporte em concreto projetado a baixas idades
This thesis presents a numerical analysis of the ground/support interaction, considering the transient behavior of the shotcrete while the gradual loading of the support occurs, due to progressive advance of the excavation face. The numerical analyses were carried out according to the finite elements method in tunnelling with circular section, under various

12. Study of purinergic receptors in glial cells from dorsal root ganglia. / Estudo dos receptores purinérgicos em células gliais do glânglio da raiz dorsal.
Purinergic receptors are expressed and play role in the sinalization between neurons and glia. In dorsal root ganglia the soma of the sensory neurons is surrounded by a layer of satellite glial cells, whose function is unclear. There are evidences that ATP is released by neurons to act on receptors in satellite cells. So far, the nature of the purinergic rec
