1. Effect of α/β Forging on Microstructure and Texture Inhomogeneity in a Ti-1023 Forged Disk
The microstructure and texture distribution of a Ti-1023 forged disk were investigated by scanning electron microscopy and synchrotron-based high-energy X-ray diffraction. The finite element method was used to simulate temperature and strain distribution in order to investigate the relationship of the α/β forging process with microstructure and texture dis

2. Avaliação e triagem da acuidade visual em escolares da primeira infância
Resumo Objetivo: Identificar a prevalência de alterações visuais em crianças de cinco anos em escolas públicas de Curitiba-PR. Métodos: As escolas foram selecionadas aleatoriamente dentro do município de Curitiba. As crianças com cinco anos completos em 2017 foram avaliadas com a tabela de Snellen, através de distância mínima correta para nitide

3. EBSD Analysis of Orientation Gradients Developed near Grain Boundaries
The local misorientation and orientation gradient development near grain boundaries (GBs) are analyzed in a deep drawing quality steel sheet (AKDQ) subjected to interrupted tensile tests in a notched sample. The microstructure is studied using electron backscatter diffraction (EBSD) with subgrain-level spatial resolution. The evolution of misorientation accu

4. DNA fingerprinting based on SSR amplification profiles for Piper species identification (Piperaceae)
ABSTRACT DNA fingerprinting based on SSR amplification profiles was applied to native species of Piper from the Atlantic Forest to compare the utility of this type of molecular marker with the morphological characters traditionally applied in Piper taxonomy and identification. Fifty-one SSR markers developed for four species of Piper native to Asia and Mesoa

5. Morphological, Structural and Optical Properties of ZnO Thin Films Deposited by Dip Coating Method
Zinc oxide (ZnO) thin films were deposited on glass substrat by dip coating technique. The effects of sol aging time on the deposition of ZnO films was studied by using the field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and optical transmission techniques. The morphology of the films strongly dep

6. Sharpness of Muqattash-Yahdi problem
Let ψ denote the psi (or digamma) function. We determine the values of theparameters p, q and r such that ψ(n) ≈ ln(n + p) -
is the best approximations. Also, we present closer bounds for psi function, which sharpens some known results due to Muqatt

7. COMINUIÇÃO SELETIVA DE MINERAIS DE DIFERENTES MOABILIDADES / COMINUIÇÃO SELETIVA DE MINERAIS DE DIFERENTES MOABILIDADES
O presente trabalho visa à melhoria da separação entre a calcita e o quartzo, explorando as diferenças na moabilidade através de um modelo matemático. O presente trabalho, através da clássica equação de Rosin-Rammler, mostra as mudanças no comportamento do minério quando submetido à operação de moagem. O estudo do parâmetro de agudez de Rosin

8. Analysis of polymerization time on abrasive wear of dental resins
An evaluation was made of the abrasive wear of six composite thermofixed dental resins subjected to different polymerization times. The method of evaluation was based on sharpness measurements to quantify the abrasive wear resistance of the resins. To this end, a test bench was built, consisting of a rotating porcelain cylinder that wears out a resin-coated

9. Association between the phonological awareness and the temporal processing in childrens with cleft lip and palate / Associação entre consciência fonológica e processamento temporal em crianças com fissura labiopalatina
Persons with cleft lip and palate presents alterations in the auditory sharpness by a big period of his lives, or by all life, because the constant tube dysfunction, that causes otitis media, stopping like this an adequate reception of the sounds of the speak. Influence of the otitis media during the childhood is one of the characteristics that is associated

10. No man is an island: John Donne e a poética da agudeza na Inglaterra no século XVII / No man is an island: John Donne and the poetics of wit in England in the early 17th century
This Ph.D. thesis examines the poetry of John Donne (1572-1631) in the light of the representative practices in the learned circles of 17th century courts. Presuming that there was an effective presence of a rhetorical institution at that time, which conditioned poetical production, I have adopted a critical methodology that displaces the classificatory limi

11. Double diffraction white light imaging without intermediary elements / Imagem por dupla difração com luz branca sem elementos intermediarios
We present the analysis of the formation of images by diffractive elements using white light by performing ray-tracing through main directions. The first system we describe is composed of two diffraction gratings and a slit, the second by two bi-dimensional spiral elements and a hole aperture, generating ortoscopic (natural relief) images. From this we had f

12. Do espírito da coisa: um cálculo de graça
This thesis proposes an understanding of the operations that are involved in a psychoanalytic trajectory by means of the sharpness and the effects produced by the Witz, understood, here, as witty and spirituous trace . In this perspective, the Witz generates a possibility of knowingtodo with the nonsense, without intending to refuse its condition of being im
