Síntese e caracterização dos 3-(benzo[c][1,2,5]calcogenodiazol-5- il)-5-(ariletinil)1,2,4-oxadiazóis derivados de (z)-n’- hidroxibenzo[c][1,2,5]calcogenodiazóis-5-carboximidamida e dos ácidos 3-arilpropiólicos
(Universidade Federal de Santa Maria, 2023-05-31)
The importance of heterocycle chemistry has grown in recent years, enabling the
connection among many interdisciplinary areas of science, standing out in synthetic organic
chemistry, mainly in the pharmaceutical area, ...
Análise da anisotropia orbital de populações de galáxias em aglomerados
(Universidade Federal de Santa Maria, 2023-07-28)
In this work we analyze the velocity anisotropy profiles β(r) of the star-forming (SF), transition
(T), AGN, and quiescent (Q) galaxy populations belonging to gaussian clusters in
order to study the impact of a galaxy’s ...
Método de baixo custo para reutilização de máscaras N95 através de recarga eletrostática
(Universidade Federal de Santa Maria, 2023-07-28)
Due to the Covid-19 pandemic, a disease caused by the Sars-CoV-2 virus, the
use of personal protective masks has increased dramatically. The World Health
Organization (WHO) recommends the PFF2 model, equivalent to the ...
O áxion em condições extremas: matéria de quarks quente e magnetizada, meios densos e estrelas compactas
(Universidade Federal de Santa Maria, 2023-07-31)
We investigate the phase diagram of quantum chromodynamics by means of the Nambu-
Jona-Lasinio effective model, including the axion - a particle which emerges as a solution
of the strong charge-parity (CP) problem and ...
Termodinâmica e transições de fase existentes na matéria de quarks com desbalanceamento quiral
(Universidade Federal de Santa Maria, 2023-07-01)
In this dissertation, we have used effective models, such as the Nambu-Jona-Lasinio (NJL)
and the Polyakov–Nambu–Jona-Lasinio (PNJL) to describe and study the Quantum Chromodynamics (QCD) phase diagram with chiral imbalance. ...
Detecção de intrusões em dispositivos de rede com o filtro de pacote Berkeley
(Universidade Federal de Santa Maria, 2023-08-04)
Modern intrusion detection systems are commonly developed using machine learning
algorithms and feature selection. However, the computational cost of these algorithms limits
the ability to respond immediately to intrusions. ...
Modelo para predição de ações e inferência de situações de risco em ambientes sensíveis ao contexto
(Universidade Federal de Santa Maria, 2015-07-31)
The availability of low cost sensors and mobile devices allowed many advances in
research of ubiquitous and pervasive computing area. With the capture of contextual data provided
by the sensors attached to these devices ...
Efeitos do momento magnético anômalo na matéria de quarks
(Universidade Federal de Santa Maria, 2023-07-28)
This work aims to investigate the effect of anomalous magnetic moment (AMM) of quarks in
the NJL and PNJL two-flavor models at finite temperature, chemical potential, and magnetic
field. To achieve this, we employed the ...
Elementos de geometria analítica: uso do aplicativo GrafEq na reprodução de obras de arte
(Universidade Federal de Santa Maria, 2015-07-16)
Desenvolvimento de sistema FI-CVG-ICP-MS para determinação de mercúrio em peixe
(Universidade Federal de Santa Maria, 2023-06-26)
Mercury (Hg) is a toxic element that can accumulate in the environment and in the food chain due to its biomagnification and bioaccumulation. A high concentration of Hg in the human body can lead to health complications, ...
