1. Resolução de inequações logarítmicas: um olhar sobre a produção dos alunos
This qualitative research was applied to students of 2nd year of high school in a Public School (Osasco-SP), with the goal to investigate procedures used by students in order to solve problems which involved inequality or logarithmic inequation. In order to reach this goal, we elaborated and selected problems which challenged in the students an investigative

2. Estudo da interferometria e polarimetria SAR em povoamentos florestais de eucalyptus SP / Sar interferometry and polarimetry study in eucalyptus sp stands
The present work aims at establishing the relationship between the forest dendrometric parameters as well as volume and biomass from stand implanted forest and the interferometric and radiometric SAR (Synthetic Aperture Radar) image response, using multivariable regression techniques. The SAR images, X and P bands, from OrbiSAR-1 sensor, were acquired from t

3. Suscetibilidades de carga e spin para uma superfície de fermi chata bidimensional
In this work we investigate the charge and spin instabilities of a two-dimensional model (d=2) of strongly interacting electrons in the presence of a at Fermi surface (FS) by using the renormalization group theory (RG). Bearing in mind the strong electronic repulsions in the cuprates superconductors, we try to relate our model to the repulsive Hubbard model

4. Correlations in charged bosons systems. / Correlações em sistemas de bósons carregados
O gás de Bose carregado foi estudado em duas e três dimensões, sendo que no caso bidimensional foram considerados dois tipos distintos de interação: l/r e ln(r). Aplicamos a esses sistemas o método do campo auto-consistente que leva em consideração a interação de curto alcance entre os bosons através de uma correção de campo local. Por meio de c

5. Linkage Analysis of Albuminuria
American Indians have a higher prevalence of albuminuria than the general population, likely resulting from a combination of environmental and genetic risk factors. To localize gene regions influencing variation in urinary albumin-to-creatinine ratio, we performed a linkage analysis and explored gene-by-diabetes, -hypertension, and -obesity interactions in a

6. Effects of molecular crowding on the interaction between DNA and the Escherichia coli regulatory protein TyrR.
Fluorescence quenching has been used to measure quantitatively the effects of sucrose and triethylene glycol on the interaction between the Escherichia coli regulatory protein TyrR and a 30-basepair oligonucleotide containing the strong TyrR box of the TyrR operon. It was observed that the apparent binding constant increased in the presence of co-solutes, th

7. Thermodynamic aspects of the linkage between binding of chloride and oxygen to human hemoglobin
Oxygen isotherms of human hemoglobin measured in distilled water and in solutions of sodium chloride in the concentration range from 0.02 to 3.0 M indicate that the oxygen affinity decreases up to about 1 M salt and then begins to increase. The isotherms obtained in the range from 0.02 to 0.6 M sodium chloride, at 37° and pH 7.4, have been analyzed in terms

8. Hemolytic Interaction of Newcastle Disease Virus and Chicken Erythrocytes. I. Quantitative Comparison Procedure
The extent to which erythrocytes are hemolyzed by Newcastle disease virus is a function of the relative concentrations of both virus and erythrocytes. Under proper conditions, the interaction of a single virus particle with an erythrocyte is sufficient to cause lysis. The extent of hemolysis is directly proportional to virus concentration only when the virus

9. Activation of thin-filament-regulated muscle by calcium ion: considerations based on nearest-neighbor lattice statistics.
We discuss the activation of thin-filament-regulated muscles by calcium ion in terms of a qualitative model based on nearest-neighbor lattice statistics. For the most part, the model takes into account only the essential features of the phenomenon--that there must be an interaction between calcium adsorption to troponin and crossbridge reaction with actin fo

10. Quantitative trait loci on chromosomes 3 and 17 influence phenotypes of the metabolic syndrome
Recent research has emphasized the importance of the metabolic cluster, which includes glucose intolerance, dyslipidemia, and high blood pressure, as a strong predictor of the obesity-related morbidities and premature mortality. Fundamental to this association, commonly referred to as the metabolic syndrome, is the close interaction between abdominal fa

11. Understanding the key factors that control the rate of β-hairpin folding
Both turn sequence and interstrand hydrophobic side-chain–side-chain interaction have been suggested to be important determinants of β-hairpin stability. However, their roles in controlling the folding dynamics of β-hairpins have not been clearly determined. Herein, we investigated the structural stability and folding kinetics of a series of tryptophan z

12. Localization of atherosclerosis susceptibility loci to chromosomes 4 and 6 using the Ldlr knockout mouse model
Atherosclerosis is a complex disease resulting from the interaction of multiple genes. We have used the Ldlr knockout mouse model in an interspecific genetic cross to map atherosclerosis susceptibility loci. A total of 174 (MOLF/Ei × B6.129S7-Ldlrtm1Her) × C57BL/6J-Ldlrtm1Her backcross mice, homozygous for the Ldlr null allele, were fed a Western-type diet
