1. Factor structure of the Dimensional Yale-Brown Obsessive-Compulsive Scale in a large sample of adults with obsessive-compulsive disorder
Objectives: Although the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a widely used instrument for assessing different obsessive-compulsive symptom dimensions, its factor structure has never been studied in a Brazilian population. Thus, we aimed to assess the goodness-of-fit indexes and factor loadings of two higher-order models of the DY-B

2. Introducing care management to Brazil’s alcohol and substance use disorder population
Brazil has a sizable alcohol and substance use disorder (ASUD) population, yet there are considerable gaps in treatment access and retention. ASUD, a chronic medical condition, is highly comorbid with medical and behavioral health disorders. This indicates a need for more targeted interventions in order to achieve health care integration (a major goal of Bra

3. Adsorption of acid blue 1 on activated carbon produced from the wood of Ailanthus altissima
Carbon prepared from the wood of Ailanthus altissima, at 400 and 800ºC was used to adsorb acid blue 1 from aqueous solution at 10ºC and 45ºC. Characterization by XRD, SEM, EDS and FTIR shows that the surfaces contain functional groups like carboxyl which disappear at 800 ºC and thus favor the exposure of more porous structural surfaces which enhance the

4. Ordem-desordem: uma avaliação estrutural do Ba(ZrxTi1-x)O3 / Order-disorder: an evaluation structural of Ba(ZrxTi1x)O3
This work have as aim, the synthesis of ceramic powders of Ba(ZrxTi1x)O3 (x = 0, 0.25, 0.50, 0.75 and 1) by the polymeric precursor method and investigate the degree of structural order-disorder of these systems by different characterization techniques, such as: thermogravimetric analysis (TA), differential thermal analysis (DTA), X-ray diffraction (XRD), Ra

5. Fate of extended states and origin of localized states in quantum Hall regime / Destino dos estados estendidos e origem dos estados localizados no regime de efeito Hall quantico
Esse trabalho é dedicado ao estudo de dois problemas de interesse atual em sistemas quânticos de baixa dimensionalidade. Ambos são relacionados ao processo de localização eletrônica no regime Hall quântico. O primeiro problema diz respeito ao destino dos estados estendidos no limite de baixos campos magnéticos ou forte desordem, onde ocorre a transi�

6. Lattice models of disorder with order
This paper describes the use of simple lattice models for studying the properties of structurally disordered systems like glasses and granulates. The models considered have crystalline states as ground states, finite connectivity, and are not subject to constrained evolution rules. After a short review of some of these models, the paper discusses how two par

7. La hostilidad y su relación con los trastornos cardiovasculares
One of the most highly developed fields in the Health Psychology area is that of the aspects involved in causing cardiac disease. Within the more thoroughly studied psychological constructs is the hostility one, component of the type A behavior pattern. Different ways of referring to this construct and of measuring it have been developed. This article analyz

8. Heuristic approach to the critical dynamics of the Ising model
We discuss order-disorder phase transitions of classical and quantum Ising models on the basis of the Ginzburg-Landau-Wilson free-energy action and a modification of a scaling method proposed by Thompson. The two-time critical relaxation scenario, driven by thermal and quantum fluctuations, respectively, is given in terms of the slow-down critical exponent o

9. A unified theory of carcinogenesis based on order–disorder transitions in DNA structure as studied in the human ovary and breast
Fourier transform-infrared/statistics models demonstrate that the malignant transformation of morphologically normal human ovarian and breast tissues involves the creation of a high degree of structural modification (disorder) in DNA, before restoration of order in distant metastases. Order–disorder transitions were revealed by methods including principal

10. Using animal models to determine the significance of complement activation in Alzheimer's disease
Complement inflammation is a major inflammatory mechanism whose function is to promote the removal of microorganisms and the processing of immune complexes. Numerous studies have provided evidence for an increase in this process in areas of pathology in the Alzheimer's disease (AD) brain. Because complement activation proteins have been demonstrated in vitro

11. Space–time thermodynamics of the glass transition
We consider the probability distribution for fluctuations in dynamical action and similar quantities related to dynamic heterogeneity. We argue that the so-called “glass transition” is a manifestation of low action tails in these distributions where the entropy of trajectory space is subextensive in time. These low action tails are a consequence of dynam

12. Neural correlates of idiographic goal priming in depression: goal-specific dysfunctions in the orbitofrontal cortex
We used functional magnetic resonance imaging (fMRI) to determine whether depressed (vs non-depressed) adults showed differences in cortical activation in response to stimuli representing personal goals. Drawing upon regulatory focus theory as well as previous research, we predicted that depressed patients would manifest attenuated left orbitofrontal cortex
