1. INSIGHT INTO THE CONFORMATIONAL SPACE OF N-BENZYL-N-(FURAN-2-YLMETHYL)ACETAMIDE BY NMR SPECTROSCOPY AND DFT CALCULATIONS
In this study, the conformational behavior of N-benzyl-N-(furan-2-ylmethyl) acetamide in chloroform was addressed by using a combined experimental/theoretical strategy using NMR spectroscopy and quantum chemical calculations. The 1H and 13C one-dimensional NMR spectra, as well as the two-dimensional HSQC-DEPT and HMBC-DEPT NMR spectra, evinced the presence o

2. The use of molecular spectra simulation for diagnostics of reactive flows
Abstract: The C2* radical is used as a system probe tool to the reactive flow diagnostic, and it was chosen due to its large occurrence in plasma and combustion in aeronautics and aerospace applications. The rotational temperatures of C2* species were determined by the comparison between experimental and theoretical data. The simulation code was developed by

3. Estudo da dinâmica de acréscimo e perda de massa na estrela T Tauri clássica V354 Mon.
The main goal of this work is to characterize the mass accretion and ejection processes of the classical T Tauri star V354 Mon, a member of the young stellar cluster NGC 2264. In March 2008, photometric and spectroscopic observations of this object were obtained simultaneously with the CoRoT satellite, the SOPHIE échelle spectrograph at the Observatoire de

4. Simulação de espectros do radical C2* para estudos de combustão / Simulation of C2* radical spectra for combustion studies
The diagnostics of particular species in combustion processes is the key for the development of combustion devices, such as burners, chambers, etc. and also to the understanding of these processes through the study of chemical reaction mechanisms with the aid of mathematical models. One of the diagnostic techniques employed with great success is the emission

8. Estudos estruturais de histatina-5 e seu análogo, TOAC0-histatina-5: interação com metais e sistemas biomiméticos / Structural studies of Histatin-5 and its analogue, TOAC0-Histatin-5: interaction with metals and biomimetic systems
The mechanism of action of histatin-5 (Hst-5), an antifungal antimicrobial peptide from human saliva is not completely clarified. Circular dichroism (CD), fluorescence, and electron paramagnetic resonance (EPR) were used to examine the conformational behavior of Hst-5 and its analogue containing the paramagnetic amino acid TOAC at the N-terminus (TOAC0-Hst-5

9. Simulação de espectros de ressonância paramagnética eletrônica (RPE) através do programa NLSL
EPR users often face the problem of extracting information from frequently low-resolution and complex EPR spectra. Simulation programs that provide a series of parameters, characteristic of the investigated system, have been used to achieve this goal. This work describes the general aspects of one of those programs, the NLSL program, used to fit EPR spectra

11. On the interaction of Bovine Serum Albumin (BSA) with cethyltrimethyl ammonium chloride surfactant: Electron Paramagnetic Resonance (EPR) study
Electron paramagnetic resonance (EPR) has been used to monitor the interaction of bovine serum albumin (BSA) with cationic cethyltrimethylammonium chloride (CTAC) at pH 7.0. EPR results using 5-DSA and 16-DSA nitroxide spin labels show that in the presence of BSA the EPR spectra are composed of two label populations, one contacting the protein and a second o
