(Universidade Federal de Santa Maria, 2017-12-13)
This paper presents the development of a Management Information Systems (MIS) prototype using data from mobile devices. The proposal involved the development of an application for product consultation and elaboration of a ...
Um protocolo de eleição tolerante a falhas e instabilidades para controladores SDN
(Universidade Federal de Santa Maria, 2017-12-11)
Software Defined Networks provide an overview of the network with
greater management flexibility. However, it ends up making the controller a single
point of failure and also susceptible to Distributed Denial of Service ...
Máquinas moleculares sintéticas: tetraalquil[2]rotaxanos como modelo no estudo de interações intramoleculares e intermoleculares
(Universidade Federal de Santa Maria, 2017-07-26)
This work presents the study of intramolecular and intermolecular interactions in tetraalkylsuccinamide[2]rotaxanes. These compounds have two submolecular components interlocked being obtained through a supramolecular ...
Determinação de hidrocarbonetos policíclicos aromáticos, níquel e vanádio em frações ácidas, básicas e neutras de asfaltos virgens e envelhecidos
(Universidade Federal de Santa Maria, 2017-08-15)
Asphalt cement (AC) is a dark-colored binder material, consisting of a mixture of naturally occurring petroleum hydrocarbons or obtained from distillation, which contains small fractions of sulfur, nitrogen, oxygen and ...
Síntese e caracterização estrutural de novos compostos organocalcogenoxanos contendo ítrio(III)
(Universidade Federal de Santa Maria, 2017-07-26)
This work describes the synthesis and structural characterization of new organochalcogenoxanes polymer and clusters compounds containing yttrium(III) ion. The synthetized compounds have structure of unidimensional coordination ...
Estrutura supramolecular de cristais multicomponentes derivados do ácido salicílico e do ibuprofeno
(Universidade Federal de Santa Maria, 2017-03-17)
This work presents the study of multicomponent crystals formed by salicylic acid (AS) with 1,2-Phenylenediamine (FEN) and 3-Amino-1,2-4-1H-triazole (TRIA) as amines; and rac-ibuprofen (IBU) with 3-amino-5-methyl-1H-pyrazole ...
Síntese e caracterização de 1,3,4-oxadiazolil-1,2,4-oxadiazóis derivados de ácidos acrílicos 3-substituídos
(Universidade Federal de Santa Maria, 2017-02-24)
A series of 1,3,4-oxadiazolyl-1,2,4-oxadiazoles was synthesized through a one-pot condensation-cyclization reaction between 3-substituted acrylic acids and 5-aryl-1,2,4-oxadiazolyl-1,2,4-oxadiazoles, and were characterized ...

(Universidade Federal de Santa Maria, 2017-03-03)
During the rainy season (october-march) over the southeast of Brazil there is a band of convective nebulosity that extends generally from the south of the Amazon to the southwest Atlantic ocean, known as the South Atlantic ...
Autoassociação de amidas aromáticas: abordagem supramolecular e mecanismos de cristalização
(Universidade Federal de Santa Maria, 2017-07-21)
This work presents the use of N-phenylamides as models for the study of self-association and intermolecular interactions. Obtaining the crystal of N-phenyltrifluoroacetamide allowed its diffraction and inclusion in the ...
Adsorção de cluster de ouro em materiais bidimensionais
(Universidade Federal de Santa Maria, 2017-07-31)
In this work, we studied the interaction of Au34 gold cluster with different two-dimensional
materials. Au clusters, differently of their macroscopic form, are chemically reactive. Their
use requires substrates. The ...
