2. Microwave Assisted Synthesis of Thiocarbamoylpyrazoles and Application as an Alternative Latent Fingermark Developers
Fingerprints are unique to each individual, contributing to human identification in forensic cases. The powder technique being widely used is considered one of the most important in latent fingermarks analysis. In this sense, the present work aimed to synthesize 1-thiocarbamoyl-4,5-dihydro-1H-pyrazoles and apply them as powder agents to develop latent finger

4. Les figures du décorateur français au XXe siècle, une histoire de mots et de pratiques
RESUMO A evolução semântica da palavra “decorador” revela os processos identitários em jogo na construção das figuras de artistas. No alvorecer do século XX na França, os novos valores desse termo têm origem na afirmação do estatuto de artista criador e na consagração da síntese das artes. Uma figura ideal de artista decorador ganha forma,

5. Titanium Dioxide Nanoparticles: Synthesis, X-Ray Line Analysis and Chemical Composition Study
TiO2 nanoparticleshave been synthesized by the sol-gel method using titanium alkoxide and isopropanolas a precursor. The structural properties and chemical composition of the TiO2 nanoparticles were studied usingX-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy.The X-ray powder diffraction pattern confirms that the particl

6. Analysis and Design of a GaAs Monolithic Tunable Polyphase Filter in S/C Bands
AbstractThis paper proposes a new topology of a 2-Stages Active Polyphase Filter (APPF) in MMIC GaAs technology. This new topology, named “radial”, allows a greater balancing of output signals phases and amplitudes, over the actual APPF’s at the state of the art. In this paper an ex-novo study is shown and synthesis formulas for the APPF are provided.

7. Advances in Computed Tomography Evaluation of Skull Base Diseases
Introduction Computed tomography (CT) is a key component in the evaluation of skull base diseases. With its ability to clearly delineate the osseous anatomy, CT can provide not only important tips to diagnosis but also key information for surgical planning. Objectives The purpose of this article is to describe some of the main CT imaging features that c

8. Evolution of Minimally Invasive Approaches to the Sella and Parasellar Region
Introduction Given advancements in endoscopic image quality, instrumentation, surgical navigation, skull base closure techniques, and anatomical understanding, the endonasal endoscopic approach has rapidly evolved into a widely utilized technique for removal of sellar and parasellar tumors. Although pituitary adenomas and Rathke cleft cysts constitute the

10. Adicção a drogas e funcionamentos limites: suas expressões e convergências no Rorschach / Drug Addiction and Borderline Personality: their expressions and convergences at Rorschach
The drug addiction is characterized through the use of a substance, to which the power of functioning as the only mean capable of bringing relief to the anguish states internally lived by an individual is attributed. There is no consensus regarding the gathering of chemically dependent patients in a specifically addictive structure, however, in spite of the

11. The role of Ca2+/calmodulin-dependent protein kinase II and calcineurin in TNF-α-induced myocardial hypertrophy
We investigated whether Ca2+/calmodulin-dependent kinase II (CaMKII) and calcineurin (CaN) are involved in myocardial hypertrophy induced by tumor necrosis factor α (TNF-α). The cardiomyocytes of neonatal Wistar rats (1-2 days old) were cultured and stimulated by TNF-α (100 μg/L), and Ca2+ signal transduction was blocked by several antagonists, including

12. Effect of ball to powder weight ratio on the mechanochemical synthesis of MoSi2-TiC nanocomposite powder
MoSi2-TiC nanocomposite powders were successfully synthesized with different ball to powder weight ratios (BPR) by ball milling of Mo, Si, Ti and graphite elemental powders. Formation of this composite was studied by X-ray diffraction (XRD). Morphology and microstructure of the milled powders were monitored by scanning and transmission electron microscopy (S
