1. Comparison of two asymmetric headgear force systems: A finite element analysis
Resumo Objetivo: o objetivo desse estudo foi usar o método de elementos finitos 3D para avaliar o efeito no padrão de deslocamento dos molares em resposta ao uso de aparelhos extrabucais com diferentes forças assimétricas. Métodos: foram confeccionados 25 aparelhos extrabucais (AEB) com diferenças, entre os lados direito e esquerdo, quanto ao compri

2. ASPECTOS TÉCNICOS E OPERACIONAIS DO USO DE MICROTURBINAS CONECTADAS AOS SISTMAS ELÉTRICOS PARA GERAÇÃO DISTRIBUÍDA DE ENERGIA / TECHNICAL AND OPERATIONAL ASPECTS OF THE USE OF MICROTURBINES CONNECT TO THE ELECTRICAL SYSTEM FOR DISTRIBUTED ENERGY GENERATION
The considerable increase in energy demand has increased the interest in reducing costs, improving reliability, quality and stability of power generation systems. The connection of distributed generation (DG) can be used as a strategic element to improve the voltage levels in power system. Microturbines (MT) have certain advantages over other models of GD, s

3. Motor de indução bifásico em rede de alimentação bifásica simétrica com condutor de retorno
The main task of this work is to provide a contribution to help a more deep understanding on the operation of the asymmetrical twophase induction motor with return for applications in places where a possibility of a two-phase network feeding exists. important contributions where obtained with the help of a time domain dynamic model for symmetrical and asymme

4. Modelo e analise do motor de indução bifasico assimetrico com o estator conectado em T
This dissertation has the aim of determining a mathematical model for asymmetrical two-phase induction motor with T-connected stator windings and to investigate some properties such as free acceleration, steady-state torque-speed characteristic and steady-state currents. This motor is designed to operate from supply of two phases and neutral, and a particula

5. Quantitative Imaging of Single Live Cells Reveals Spatiotemporal Dynamics of Multistep Signaling Events of Chemoattractant Gradient Sensing in DictyosteliumD⃞V⃞
Activation of G-protein-coupled chemoattractant receptors triggers dissociation of Gα and Gβγ subunits. These subunits induce intracellular responses that can be highly polarized when a cell experiences a gradient of chemoattractant. Exactly how a cell achieves this amplified signal polarization is still not well understood. Here, we quantitatively measur

6. Low-frequency characteristics of intracellularly recorded receptor potentials in guinea-pig cochlear hair cells.
Intracellular receptor potentials were recorded from inner and outer hair cells in response to low-frequency tones, from the basal, high-frequency region of the guinea-pig cochlea. The receptor potentials recorded from inner hair cells are asymmetrical about the resting membrane potential with the depolarizing phase, which corresponds to rarefaction in sound

7. Growth patterns in euconodont crown enamel: implications for life history and mode-of-life reconstruction in the earliest vertebrates.
Euconodonts were the first vertebrates to produce a mineralized skeleton. It is concluded that the minor increments in the crown enamels of Protopanderodus varicostatus and Drepanodus robustus are probable homologues of the cross striations in hominoid enamel, although they are much more variable in thickness and represent daily to weekly growth. Major incre

8. Probing the ethanol-induced chain interdigitations in gel-state bilayers of mixed-chain phosphatidylcholines.
Using high-resolution differential scanning calorimetry (DSC), we have studied the effects of ethanol concentrations, [EtOH], on the main phase transition temperatures (T[m]) of the following mixed-chain phosphatidylcholines (PCs): C(15):C(17)PC, C(17):C(15)PC, and C(12):C(20)PC. These lipids have a common molecular weight; however, their apparent acyl chain

9. Subunit Topology of Two 20S Proteasomes from Haloferax volcanii
Haloferax volcanii, a halophilic archaeon, synthesizes three different proteins (α1, α2, and β) which are classified in the 20S proteasome superfamily. The α1 and β proteins alone form active 20S proteasomes; the role of α2, however, is not clear. To address this, α2 was synthesized with an epitope tag and purified by affinity chromatography from reco

10. In Vitro Low-Level Resistance to Azoles in Candida albicans Is Associated with Changes in Membrane Lipid Fluidity and Asymmetry
The present study tracks the development of low-level azole resistance in in vitro fluconazole-adapted strains of Candida albicans, which were obtained by serially passaging a fluconazole-susceptible dose-dependent strain, YO1-16 (fluconazole MIC, 16 μg ml−1) in increasing concentrations of fluconazole, resulting in strains YO1-32 (fluconazole MIC, 32 μg
