Published: November 2021

The form of a given case settlement may be specified directly in a provision of substantive law or result indirectly, i.e. through the existence of an administrative and legal relationship determining a change in the legal situation of an individual (granting a specific right or obligation). In the second case, it is justified to apply the presumption of the form of an administrative decision, approved of in the doctrine and judicature. However, such a regulation should be introduced into the provisions of the Code of Administrative Procedure.

Published: November 2021

ABSTRACT Background: Although epilepsy is primarily known as a cortical disorder, there is growing body of research demonstrating white matter alterations in patients with epilepsy. Objective: To investigate the prevalence of white matter hyperintensities (WMH) and its association with seizure characteristics in patients with epilepsy. Methods: The prevalence of WMH in 94 patients with epilepsy and 41 healthy controls were compared. Within the patient sample, the relationship between the presence of WMH and type of epilepsy, frequency of seizures, duration of disease and the number of antiepileptic medications were investigated. Results: The mean age and sex were not different between patients and healthy controls (p>0.2). WMH was present in 27.7% of patients and in 14.6% of healthy controls. Diagnosis of epilepsy was independently associated with the presence of WMH (ß=3.09, 95%CI 1.06-9.0, p=0.039). Patients with focal epilepsy had higher prevalence of WMH (35.5%) than patients with generalized epilepsy (14.7%). The presence of WMH was associated with older age but not with seizure characteristics. Conclusions: WMH is more common in patients with focal epilepsy than healthy controls. The presence of WMH is associated with older age, but not with seizure characteristics.

ABSTRACT Background: self-limited epilepsy with centrotemporal spikes, previously considered benign focal childhood epilepsy with centrotemporal spikes show clinical signs of involvement of Rolandic areas, mainly lower area, which may affect the planning and execution of motor sequences. Objective: This study aimed to evaluated oral praxis in children with self-limited epilepsy with centrotemporal spikes and compare to the age-matched control group. Methods: This was a descriptive study with 74 children with self-limited epilepsy with centrotemporal spikes, with the classical forms according to International League Against Epilepsy, and between 4 and 15 years of age, selected from the child neurology outpatient clinic of the Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo, São Paulo, Brazil, and 239 age-matched and educational level-matched (convenience sampling) control children. All children were submitted to the battery of oral volitional movements, which consisted of 44 tests for oral movement (tongue, lip, cheek, jaw, and palate) and 34 phonemes and consonant cluster tasks, with simple and sequenced oral movements. Results: The mean age and standard deviation (SD) of children with epilepsy was 9.08 years (SD 2.55) and of controls 9.61 years (SD 3.12). The results showed significant differences between the groups with a poorer performance of children with epilepsy compared to children without epilepsy in simple and particularly in sequenced movements. Conclusion: These findings can be attributed to the genetically determined immaturity of cortical structures related to motor planning in children with self-limited epilepsy with centrotemporal spikes.

Published: November 2021

ABSTRACT Chickpea growth and yield are related to the balanced supply of N. In weathered soils, this factor depends on the biological activity of growth-promoting bacteria, the presence of diazotrophic bacteria, and the management of nitrogen fertilization. In this regard, this study aimed to evaluate the efficiency of inoculation with a mix of Bacillus spp. and N levels on chickpea cultivation. Two experiments were carried out: area 01, characterized by shortest cultivation time and area 02, with the longest cultivation time. For both studies, the experimental design was in randomized blocks with four replications arranged in a 2 x 6 factorial consisting of the absence or presence of the mix of Bacillus spp. (1 x 107 CFU per mL) from root isolates and six N levels: 0, 25, 50, 75, 100, and 125 kg ha-1. The chickpea production and yield characteristics were evaluated. In the area 01, inoculation with the mix of Bacillus spp. did not interfere with grain yield, whereas the application of lower N levels (25 kg ha-1) increased the dry mass of branches, grains, total dry mass, and yield (4.17 t ha-1). In contrast, in the area 02, nitrogen fertilization increased the chlorophyll index but did not interfere with the remaining production variables, whereas inoculation with Bacillus spp. increased chickpea yield by 4%, resulting in a grain harvest of 4.16 t ha-1. Therefore, inoculation of chickpea seeds with the mix of Bacillus spp. is recommended in soils with long-time cultivation of agricultural species.

Buscou-se mapear a rede de cuidados em Saúde Mental em uma Unidade de Saúde da Família (USF) de Salvador, Bahia, Brasil, traçando as relações do cuidado para compreender as convergências e controvérsias da abordagem psicossocial na Atenção Primária à Saúde. A cartografia, fundamentada na Teoria do Ator-Rede, acompanhou vivências de quatro pessoas com histórico de sofrimento psíquico por meio do diário de campo, de observação participante, entrevistas semiestruturadas e pesquisa documental. Analisaram-se: situação de agudização do sofrimento; relação entre pessoas da equipe de saúde; construção da responsabilização familiar; e embate entre agenciamento e determinação. Os elementos emergentes convergiram para o intuito de elaborar meios possíveis de lidar com o adoecimento, na relação consigo e com o outro, em vez de priorizar a adequação a uma norma social do que é o ser saudável.
Marcadores de infecciones transmisibles vía transfusional: el caso del banco de sangre de la Escuela de Microbiología de la Universidad de Antioquia, 2015-2016
Authors:   Universidad Cooperativa de Colombia, Cardona-Arias Jaiberth Antonio , Flórez-Duque Jenniffer
Published: November 2021

Este libro de investigación tiene como objetivo estimar la seroprevalencia de marcadores de infección transmisibles vía transfusional y sus factores asociados en donantes que asisten al banco de sangre de la Escuela de Microbiología de la Universidad de Antioquia, en el periodo 2015-2016. Los estudios previos en nuestro medio presentan limitaciones relacionadas con el hecho de no poder extrapolarse a la población de esta investigación, dado que no tienen en cuenta los nuevos marcadores de infección que se incluyeron en el 2014 para la tamización en bancos de sangre; no se hacen análisis desagregados por subgrupos de interés en términos sociodemográficos y hematológicos. Se realizó un estudio descriptivo transversal, en el cual se estimó la seroprevalencia global de infecciones transmisibles en el banco de sangre, así como la prevalencia específica de vih, htlv, vhb, vhc, T. pallidum y T. cruzi. La seroprevalencia global de infecciones fue de 3,39%, que en términos epidemiológicos puede considerarse una ocurrencia baja, aunque desde el punto de vista de la medicina transfusional se podría considerar alto, dado que esta proporción representa un elevado número de donantes diferidos y unidades de sangre descartadas, a lo que podrían sumarse las implicaciones que esta cifra tiene para el banco de sangre y su proceso de selección de donantes. Este estudio presenta múltiples ventajas, como trabajar con datos poblacionales, exponer la magnitud de la ocurrencia de infecciones que no se incluyen rutinariamente en los programas de vigilancia epidemiológica activa de Colombia e identificar grupos con mayor ocurrencia de infecciones. A su vez, tiene ventajas de los estudios descriptivos como: generar hipótesis, estudiar simultáneamente varios eventos y varios factores de exposición, permitir la investigación de infecciones de larga duración o desarrollo lento, y orientar acciones de planeación y administración de servicios de salud.
Preparation and Characterization of Biocompatible Membranes Based on TiO2 Nanoparticul
Authors: TAŞKIN ÇAKICI Gülşen
Published: November 2021

In this study, biocompatible composite membranes of sodium alginate/hydroxypropyl methylcellulose (NaAlg/HPMC) based on nano-titanium dioxide (n-TiO2) were prepared. Regarding the preparation processes of these membranes, the amount of citric acid [5%, 15%, 30% (w/w)] added to the NaAlg/HPMC blend, the crosslinker type (glutaraldehyde, acetone/water with glutaraldehyde, CaCl2), and the amount of n-TiO2 [5%, 15%, 20% (w/w)] were studied and optimum conditions were determined. When the equilibrium swelling values were examined, it was observed that the one with the least swelling was the CaCl2 crosslinked membrane. Fourier Transform Infrared (FTIR) Spectroscopy, Differential Scanning Calorimetry (DSC), and Scanning Electron Microscopy (SEM) were used to characterize the modified crosslinked membranes. The FTIR analysis results showed the formation of hydrogen bonds between the hydroxyl groups of the HPMC and NaAlg polymer chains. The DSC analysis showed the existence of single glass transition temperature (Tg) which indicated the compatibility and physical interaction between the NaAlg and HPMC polymer chains for NaAlg / HPMC mixtures.

Verseghy Ferencet a Martinovics-összeesküvésben való részvétel vádjával 1794. december 11-én tartóztatták le. A mozgalom leleplezésének ekkorra már híre ment az érintettek körében, akiknek módjuk nyílt arra, hogy minden olyan írásukat megsemmisítsék, amelynek tartalmát terhelőnek ítélték. Feltehetően Verseghy is így tett, hisz csupán egy vékony köteg őrzi az elfogatásakor tőle lefoglalt iratokat. Hogy mégis volt mit elkobozni tőle, két körülményre utalhat. Részint arra, hogy ő talán későn értesült: nem volt lehetősége teljességre törekvően eljárni. Részint arra, hogy az el nem égetett írásokat nem tekintette magára nézve terhelőnek. Hogy végül minek is köszönhetik fennmaradásukat e szövegek, arra évszázados távolból aligha derülhet már fény. Teljesen bizonyos azonban, hogy ha egykori birtokosuknak nem is, a 18. század iránt érdeklődőknek feltétlenül hasznos, hogy e források nem váltak pernyévé. E dolgozat arra vállalkozik, hogy közülük az egyiket górcső alá véve kísérletet tegyen közelebbről is szemügyre venni a régi századvég eleddig csupán néhány utalásból ismert szellemi közösségét, a pesti olvasótársaságot.

Characterization of Human Astrocyte Senescence
Authors:   , Crowe Elizabeth Patricia , Sell Christian , Torres Claudio A.
Published: November 2021

Aging is a major risk factor for cognitive decline and neurodegenerative disease. A key feature of the basic biology of aging is cellular senescence. Cellular senescence is classically defined as an essentially irreversible proliferative growth arrest that is telomere-based, but it can also be induced prematurely by stressors. Senescent cells undergo widespread changes in gene expression, demonstrate an altered, pro-inflammatory secretion pattern, accumulate in tissues during aging and at sites of age-related pathologies in the periphery and it is thought that senescent cells contribute to an age-related decline in tissue function and tumor formation. However, little is known about the potential for central nervous system (CNS)-derived cell types to undergo senescence or their relevance to aging-related cognitive decline and neurodegenerative disease. Given that astrocytes are a highly abundant population of glial cells that perform myriad of complex functions in the CNS in order to maintain homeostasis, the loss of astrocyte function or the gain of neuroinflammatory function as a result of senescence could have profound implications for aging brain and neurodegenerative disorders including AD. We found that human astrocytes exhibit classic biomarkers of the senescent phenotype in vitro in response to exhaustive replication, oxidative stress, and amyloid-beta. To better understand senescence-associated changes in astrocytes at the molecular level, we investigated global changes in the astrocyte transcriptome using a whole transcriptome sequencing method (RNA-seq) following the induction of oxidative stress-induced senescence. Senescent astrocytes downregulate the expression of brain-enriched genes involved in neuronal differentiation and development suggesting a loss of differentiated function in these cells. In addition, senescent astrocytes acquire an inflammatory phenotype indicative of the senescence-associated secretory phenotype (SASP), which seems to be regulated by p38MAPK. In order to begin to establish the physiologic relevance of astrocyte senescence to aging brain and AD, we examined post-mortem frontal cortex for biomarkers of senescence and for glial fibrillary acidic protein (GFAP) to identify astrocytes and found that during aging and AD there is a significant increase in population of senescent astrocytes. Overall, these studies suggest that senescent astrocytes are a component of the age-related neurodegeneration.

Void Hunting
Authors: Paustian John B.
Published: November 2021

Karst environments are characterized by voids, i.e. sinkholes and conduits of varying size that arise from the active
dissolution of carbonate rock by acidic groundwater. These voids, whether air-, water-, or soil-filled, can be difficult
to image using near-surface geophysical methods due to the limited investigation depths of most active-source methods. In
addition, due to the significant effort it takes to collect active-source data, investigators are often unable to monitor
spatio-temporal variations in the subsurface. The ability to detect, image, and monitor subsurface voids improves the
understanding of processes that create and transform voids, a vitally important insight across a variety of scientifc
disciplines and engineering applications, including hydrogeology, geotechnical engineering, planetary science and even
issues of national security. Using a 54-element nodal array (1C and 3C sensors), I image the subsurface of the USF GeoPark
with ambient noise surface wave tomography. I also use complementary active-source geophysical datasets (e.g. 2D ERT)
collected at the GeoPark to constrain and/or validate the tomography results. I address two research questions with
this study: (1) How do ambient seismic methods complement active-source near-surface methods? (2) Can ambient noise
tomography resolve voids in the karst environment? In this thesis, I discuss my answers to these questions and present
the current state of surface wave methods in the karst environment, including the feasibility for utilizing ambient
noise methods to monitor spatio-temporal changes in sinkhole and conduit formation. In addition to the ability to use
seismic methods for temporal monitoring, ambient noise provides lower frequencies than what are achievable with active-source
seismic methods. Using frequencies from 5-28 Hz, ambient noise tomography is able to image deeper into the subsurface (up to
100 m at 5 Hz) than previous active-source seismic studies at the GeoPark field site. This study yields a more robust and
simple method to image voids in covered karst environments and a long-term installation of ambient seismic nodes enables
future investigations of spatio-temporal variations in void structures.
Application of in situ and ex situ Characterization of Atomic Layer Deposition Processes for Gallium Phosphide and Sodium Fluoride
Authors: Kuraitis Sara Rose
Published: November 2021

Atomic layer deposition (ALD) is a vapor deposition technique for synthesizing thin films with nanometer thickness control.
ALD films are deposited on a substrate surface in a cyclic layer-by-layer fashion utilizing alternating doses of highly
reactive chemical precursors. Precursors are selected to undergo self-limiting chemical reactions with the surface, and
desired film thickness is achieved by varying the number of ALD cycles accordingly. Optimization of ALD process parameters
and precursor chemistry enables conformal coating of arbitrary substrate geometries, including high aspect ratio features
such as trenches. In the decades since its introduction, ALD has been used for applications across many industries,
including semiconductor device manufacturing, emerging battery technologies, and optoelectronics.

In this work, I present investigation of two previously reported chemistries for ALD of gallium phosphide (GaP), as well
as improvements made to a custom ALD reactor to facilitate better process control and characterization. I also present a
new process for thermal ALD of sodium fluoride (NaF), with potential applications in electrode coatings for sodium-ion
batteries. To my knowledge, this is the first report of NaF ALD. Finally, I summarize obstacles which may be addressed
in future studies that build upon this work.
Local Ecological Knowledge Exchange of Steelhead
Authors: Weisenfluh Mikaela A.
Published: November 2021

Local ecological knowledge (LEK) has been researched in the past to examine how it can aid and support
scientific ecological knowledge (SEK). SEK is often seen as the preferred and superior type of knowledge when
dealing with environmental changes. However, both of these types of knowledge are not segregated within individuals
but are dependent on age, experience with the fishery, experience with a scientific organization, and/or perception
of changes in the environment based on lived experiences. Interactions between LEK and SEK users is valuable to the
conservation that is needed to protect these fish species and is dependent on how well these groups are sharing their
knowledge and communicating with one another. For this study, I have examined the exchange of knowledge on steelhead
trout within Idaho between anglers, Idaho Fish & Game, and the Office of Species Conservation. If these three groups
are sharing SEK and LEK effectively, despite generational and organizational differences, then the variation between
groups should be low. In addition to the exchange of knowledge, I have looked at communication, the meaning behind
each group’s knowledge, and how age and experience play a factor into their perception of change. Of those that
responded to the questionnaire, there were 26 angler respondents, 21 Idaho Fish & Game respondents, and 6 Office of
Species Conservation respondents. Statistical tests indicated that there was a significant difference in LEK scores
between groups, and there was low communication between the Office of Species Conservation and anglers. There was a
significant difference in where these groups reported that most of the mortality for steelhead occurred, and age and
experience did not have an impact on LEK scores. These results indicate that there is variation between groups’ LEK
which could be due to variations in LEK between groups. How groups define local can cause variation between groups’ LEK.
Into the Unknown

Published: November 2021

Mental health disorders (MHD) are a rising, yet stigmatized, topic. With statistics reporting that one in five
adults in the United States will be afflicted by a MHD in their lifetime, researchers have begun exploring the
behavioral nuances that emerge from interactions of these individuals with persuasive technologies, mainly social
media. Yet, there is a gap in the analysis pertaining to a persuasive technology that is part of their everyday lives:
search engines (SE). Each day, users with MHD embark on information seeking journeys using SE. Every step of the search
process for better or worse has the potential to influence a searcher’s state of mind. In this thesis work, we empirically
investigate what subliminal stimulus SE present to these vulnerable individuals during their searches. We do so by utilizing

Modeling and Analyzing Users' Privacy Disclosure Behavior to Generate Personalized Privacy Policies
Authors: Mehdy A.K.M. Nuhil
Published: November 2021

Privacy and its importance to society have been studied for centuries. While our understanding and continued theory
building to hypothesize how users make privacy disclosure decisions has increased over time, the struggle to find a
one-size solution that satisfies the requirements of each individual remains unsolved. Depending on culture, gender,
age, and other situational factors, the concept of privacy and users' expectations of how their privacy should be
protected varies from person to person. The goal of this dissertation is to design and develop tools and algorithms
to support personal privacy management for end-users. The foundation of this research is based on ensuring the
appropriate flow of information based on a user's unique set of personalized rules, policies, and principles. This
goal is achieved by building a context-aware and user-centric privacy framework that applies insights from the users'
privacy decision-making process, natural language processing (NLP), and formal specification and verification
techniques. We conducted a survey (N=401) based on the theory of planned behavior (TPB) to measure the way users'
perceptions of privacy factors and intent to disclose information are affected by three situational factors embodied
by hypothetical scenarios: information type, recipients' role, and trust source. To help build usable privacy tools,
we developed multiple NLP models based on novel architectures and ground truth datasets, that can precisely recognize
privacy disclosures through text by utilizing state-of-the-art semantic and syntactic analysis, the hidden pattern of
sentence structure, tone of the author, and metadata from the content. We also designed a methodology to formally model,
validate, and verify personalized privacy disclosure behavior based on the analysis of the users' situational decision-making
process. A robust model checking tool (UPPAAL) is used to represent users' self-reported privacy disclosure behavior by an
extended form of finite state automata (FSA). Further, reachability analysis is performed for the verification of privacy
properties through computation tree logic (CTL) formulas. Most importantly, we study the correctness, explainability,
usability, and acceptance of the proposed methodologies. This dissertation, through extensive amounts of experimental
results, contributes several insights to the area of user-tailored privacy modeling and personalized privacy systems.
Collagen XI Impact on Structure and Function of the Vertebrate Inner Ear in a Zebrafish Model
Authors: Hardy Makenna
Published: November 2021

The ear is essential to maintaining balance and hearing; both of which can be linked to one another and significantly impact a
person’s quality of life. Although aging and damage are more common reasons for hearing loss, congenital ear defects still have
a considerable impact on our population. The function of the ear can be affected by structural deformities to the ear and its
components which results in hearing loss. Mutations and single nucleotide polymorphisms in the gene encoding Collagen XI alpha
one chain (COL11A1) protein can play a role in hearing and balance dysfunction in humans as seen in disorders such as Stickler
Type 2 and Marshall Syndrome, and nonsyndromic hearing loss deafness autosomal dominant 37 (DFNA37). Due to its transparency,
external fertilization, the zebrafish model system was used to create a COL11A1 zebrafish counterpart (Col11a1a) knockdown and
knockout genetic model. This research highlights the importance of Col11a1a in the development and structure of the inner ear
as a whole including the hair cells, kinocilia, and otolith formation. Studying the development and structural changes of the
inner ear can provide insight into hearing loss and potential interventions.
A Framework for Unity

Colombia’s civil war, the longest war in modern history, finds itself at an inflection point in which either peace can slowly be attained or war can consume the country again. This article lays out a plan for a peace deal between the Colombian government and the agrarian Marxist ELN, taking the 2015 peace deal between the government and the leftist FARC as a point of reference. Despite a conservative administration that is hostile to peace currently in power, there are several tangible opportunities that make the next few months ripe for peace. The election of Joe Biden, the COVID-19 pandemic, and the growing unpopularity of the conservative approach to war can all facilitate the ELN coming to the negotiation table. This article lays out an ELN peace deal focused on agrarianism, inclusiveness, illegal drugs, and victims’ rights, and concludes with short-, mid-, and long-term goals to achieve peace.

Background: Metacarpal fractures comprise approximately 35.5% of cases in daily emergencies, mostly due to road traffic accidents, fall, and assault. The main goal of treatment is to achieve the strong bony union without any functional disability. Aim of the study was evaluation of functional outcome of metacarpal fractures managed by operative techniques and to compare the efficacy of different operative techniques.Methods: A total of 50 patients managed by various operative techniques by using k-wires, screws and plates. Functional outcome was assessed by using total active movement (TAM) and disabilities of the arm, shoulder and hand (DASH) scoring system at 6th week, 3rd month and at 6th month.Results: A total 47 fractures united and three fractures mal-united at the time of final assessment. Overall excellent and good results were achieved in 94% cases.Conclusions: Our finding suggests that open reduction and internal fixation with k-wire is most preferable method among all other operative techniques.
Gastric duplication cyst: rare cause of upper gastrointestinal bleeding in a young adult, with a review of literature
Authors: Loong Philip Ding Hsin , Fan Ling Li , Ramasamy Umasangar
Published: November 2021

Duplication cyst along the alimentary canal is a congenital anomaly which is rare and usually incidentally found at endoscopy or radiological imaging. It can develop anywhere along the alimentary canal with only 4% occurrence in the stomach. Only few cases of gastric duplication cysts were reported to be symptomatic along with its complications. Diagnostic modalities include oesophageo-gastroduodenoscopy (OGDS), endoscopic ultrasound (EUS), computerized tomography (CT) scan and magnetic resonance imaging (MRI). However, the best option to confirm the diagnosis is complete resection of the lesion. We are reporting about a teenage girl whereby she presented with sudden episodes of hematemesis, which led to a syncopal attack. She also complained of intermittent central abdominal pain for a month prior to her presentation. Physical examination was unremarkable. However, her blood investigation showed a significant drop in hemoglobin. The patient had an endoscopy during which a submucosal lesion at the greater curvature was identified and the provisional diagnosis we had was a gastrointestinal stromal tumor (GIST). CT scan of the abdomen was also done showing an endoluminal cystic gastric lesion measuring approximately 2×2×2 cm. The lesion was confined to the stomach with no local infiltration of the adjacent structures. Decision was made to proceed with a laparoscopic wedge resection after outweighing the risk and benefits of surgery. Gastric duplication cyst is a rare anomaly. Despite its rarity, it should be included as a differential when we encounter a submucosal lesion due to its tendency for malignant transformation and other complications.

A widespread increase in the prevalence of fungal infections has been documented in recent decades. Candida albicans infections, which are frequently refractory and linked with high morbidity and mortality, place a significant burden on public health, despite the fact that existing antifungal medicines are restricted and associated with toxicity. Fungi are one of the most underappreciated killers, as evidenced by the fact that Amphotericin B and other commercially available antifungal therapies are still recognized as gold standards. The majority of commonly used antifungal medications have toxicity, effectiveness, and cost disadvantages. As a result of these limitations, there is a growing demand for the development of a novel antifungal medication treatment that acts selectively on new targets while having the fewest adverse effects. Natural goods, whether as pure phytocompounds or regulated plant extracts, give prospects for the development of lead compounds that may subsequently be turned into diverse synthetic medications with the appropriate alterations. These herbs can also be used as a component of a herbal synthetic combination, lowering the minimum required dose of the synthetic medicine (when taken singly) and reducing the risk of adverse effects. The goal of this research is to reduce the minimum required concentrations of today's antifungal medications by mixing them with a few less well-known herbal extracts while maintaining their efficacy.
Ensino de Relações Internacionais na Modalidade a Distância: Original Article a Experiência do Curso de Administração Pública Semipresencial
Authors: Neto Francisco Daniel
Published: November 2021

O presente trabalho tem como objetivo principal analisar as ferramentas integrativas no desenvolvimento do Ensino a Distância (EaD) na disciplina de Relações Internacionais, no âmbito do curso semipresencial de Administração Pública da Universidade Federal Fluminense (UFF), que é oferecido em parceria com o Centro de Educação a distância do Rio de Janeiro (CEDERJ). Tal análise faz-se necessária devido à expansão do EaD no Brasil como ferramenta de inclusão educacional e, especialmente no espaço em questão, de consolidação de canais dialógicos de ensino voltados para as Relações Internacionais. Que possuem um caráter interdisciplinar e abrangente, além de agregar ao conteúdo programático da disciplina, diversos campos do conhecimento formativo dos gestores públicos sob a perspectiva da esfera internacional. Para isto, foi aplicado o mesmo questionário semiestruturado para os alunos participantes da disciplina no primeiro semestre dos anos de 2017 e 2019. Neste sentido, é possível verificar que a disciplina de Relações Internacionais (RI) do curso de Administração Pública semipresencial oferece instrumentos virtuais padrões do sistema Moodle/CEDERJ, como as Atividades a distância (ADs) e outros instrumentos padrões (quadro de avisos, sala de tutoria, entre outros), além de alguns instrumentos adicionais como: o uso de chats, e a adoção de vídeos, textos e blogs como materiais complementares. De maneira geral, os alunos consideram que a disciplina é bastante interativa. No entanto, espaços fundamentais, como a sala de tutoria ainda não são percebidos como efetivos para a promoção de diálogos e a construção de novos conhecimentos.

Fault diagnosis with states estimation in PV systems
Authors: Plazas Rosas Ramiro Alejandro , Franco Mejia Édinson , Orozco Gutiérrez Martha Lucía
Published: November 2021

The photovoltaic systems are electrical, electronic, and mechanical elements. These systems also face different environmental and operating conditions susceptible to failure. In addition, photovoltaic systems can be the only source of electricity generation, and an affectation on the energy supply can harm the community. In many places, photovoltaic systems are the only source of energy because they are not part of what is known in Colombia as the National Interconnected System (SIN). Which comprises the direct connection between large generators (hydroelectric and/or thermal plants) and consumers. In fact, PV system damage would affect food refrigeration or everyday things like charging a cell phone. Therefore, it is necessary to register, monitor the operation elements of PV systems, and develop strategies that allow the diagnosis to detect faults. In this work, we propose a fault-diagnosis using the PV systems measurements that is, power converter, photovoltaic panels with also mathematical models to determine the deviation between the estimated and measured signals as voltages and currents.
Dual gate material (Au and Pt) based double-gate MOSFET for high-speed devices
Authors: Gowthaman Naveenbalaji , Srivastava Viranjay M
Published: November 2021

Aluminium Gallium Arsenide (AlGaAs) is a semiconductor material used in the latest design of double heterostructure laser diodes. This semiconductor is mostly available in the arbitrary alloy form between Gallium Arsenide and Aluminium Arsenide. It is derived from the Tri-MethylGallium (TMG/TMGa), and Arsine (AsH3), both the chemicals are pyrophoric and toxic. The resistance is less between source and drain contacts in the case of AlGaAs so that it has been proposed as a material to grow contacts on Indium Phosphide (InP) layer. The AlGaAs uses an ion implantation model for a design purpose which lowers the thermal power while the operation of the device. The parasitic capacitance has to be taken care of while designing a device using this material since the capacitance affects much in the AlGaAs based devices. The average velocity of the electrons has been observed to be increased by 14.63 % in the Au-gate (gate-1) and Pt-gate (gate-2) material-based Double-Gate (DG) MOSFET compared to the Silicon-based DG MOSFET. This paves the way for higher electron mobility, in turn, it can be used in highfrequency device manufacturing. The proposed material can be used in high-speed hybrid applications such as HEMTs and radiofrequency devices for long-haul communication.
