Utilización del patrón wrapper para traducir a lenguaje java los algoritmos escritos en lenguaje c que usan punteros y sus implicaciones educativas
Authors: Vera-Contreras Milton Jesús
Published: July 2021

El presente documento muestra a estudiantes y profesores la posibilidad de utilizar el lenguaje Java como herramienta para el aprendizaje de la programación en sustitución al tradicional lenguaje C. Se centra en el problema particular del uso de punteros en la implementación de algoritmos en C al intentar migrarlos a Java [1, 2, 3]. Muestra, mediante la utilización del patrón estructural Wrapper [4], que los algoritmos implementados en C son fácilmente traducibles a lenguaje Java [2] sin modificaciones considerables en la codificación. Finalmente sugiere implicaciones del uso de Java como lenguaje en el aprendizaje de la programación. Se pretende ir    mucho más allá del acto investigativo y de la escritura del artículo, persiguiendo   sembrar la importancia de   arriesgarse a escribir, de   proponer ideas, de crear y   recrear la ciencia y la tecnología. En ocasiones, el estudiante y el profesor   consideran como obvias [5] ciertas cosas dentro del acto educativo, el salón de clase, las cuales encierran, como en éste caso,  situaciones ocultas que sólo    con el tiempo se reflejan, situaciones que bien pueden ser tomadas por objeto de estudio de una investigación. Muchas de las ideas enunciadas en el presente artículo pretenden   ser objeto de   estudio    en una propuesta de semillero de   investigación, llamado ALGOMÁTICA [6], donde se busca conjugar el formalismo y la praxis de la programación de computadores, fomentando un espíritu investigativo al tiempo que se gestan situaciones propicias para crear ciencia y tecnología.Palabras Clave: Programación de Computadores; Programación Orientada a Objetos; Lenguaje Java; Patrones de Software; ALGOMÁTICA
Transgenicos: un reto a la evolucion
Authors: Camargo Omar
Published: July 2021

Los organismos multuicelulares de muchas clases y grados de complejidad aparecieron en los ultimos 600 millones de años y ahora llenan virtualmente todos los ambientes habitables de la tierra .Hace un poco mas de 1.500 millones de años aparecieron por primera vez sobre la tierra los eukariotes ,los cuales se desarrollaron de formas procarioticas ,unicas habitantes del planeta hasta entonces .Los cambios evolutivos en los organismos originados a traves de la seleccion natural y las mutaciones neutras trajeron consigo el desarrollo de estrictas barreras naturales que impiden la entrada de un gen foraneo al exclusivo pool genetico que caracteriza cada especie , asi como la entrada deADN foraneo a cualquier celula .                                        La biotecnologia de los trasgenicos a traves de su principal herramienta ,la ingenieria genetica , ha transgredido estas antiquisimas  barreras naturales ,facilitando el intercambio de genes entre celulas ,individuos ,especies , incluso entre procariotes y eukariotes.Un gen modificado de cualquier organismo (trasgen), el cual puede terner una parte de un gen viral, otra parte de un gen bacteriano y otra parte de un gen de mamifero por ejemplo  ,puede ser producido en el laboratorio e introducido en un grupo de organismos (bacterias,levaduras ,mamiferos...)quienes lo integraran  a su propio genoma y lo expresaran.                    Las aplicaciones e implicaciones de esta biotecnologia estan teniendo y tendran un profundo impacto en los campos investigativo ,biomedico y comercial .Los costos ,las perspectivas futuras y algunas consideraciones bioeticas tambien seran aspectos que se trataran en el presente articulo.Palabras clave: biotecnología, ingeniería genetica, transgene, evolución.

Estudio de un modelo de ventilación para un tunel de flujo vehicular
Authors: Acevedo-Peñaloza Carlos Humberto
Published: July 2021

El objetivo principal del estudio es determinar si el modelo de ventilacion axial sin introduccion de aire fresco es adecuado para mantener los niveles decontaminacion en el tunel dentro de los limites permisibles para el ser humano ,para un caso critico de flujo vehicular.Para realizar el estudio se utilizan dos modelos, uno computacional y uno experimental a escala .Para el modelo computacional se utiliza el software de elementos finitos ANSYS-FLOTRAN con el cual se simula tanto el tunel real como el prototipo . El modelo experimental es construido cumpliendo la similitud geometrica ;para el caso de la similitud dinamica se lleva el flujo a regimen turbulento para observar el comportamiento de este cualitativamente y compararlo con el modelo experimental.                                                                                                                Los resultados obtenidos con los modelos muestran que , en cada tramo de ventilacion , se presenta recirculacion local cerca del ventilador .En cada zona de recirculacion se presentan dos puntos de estancamiento en los cuales los trazadores utilizados se acumulan.                                                                                                Segun el alcance de las pruebas realizadas se concluye que el sistema de ventilacion propuesto es cualitatvamente bueno, sin embargo amerita un estudio profundo para analizar cuantitativamente el impacto de la recirculacion en la concentracion de contaminantes.Palabras clave: Simulación, contaminación, elementos finitos, túnel.

Authors: Vasquez-Quijano Adiel Alberto , Chacon-Rangel Jhollman , Caballero-Chaparro Margarita
Published: July 2021

Los probióticos son aquellos microorganismos vivos que, al ser agregados como suplemento en la dieta, afectan en forma beneficiosa el desarrollo de la flora microbiana no patógena en el intestino y estimulan las funciones protectoras del sistema digestivo. En este trabajo se presentan resultados con respecto a la caracterización de la flora intestinal anaerobia predominante en aves adultas sanas del municipio de Los Patios. Se identificaron, con género y especie, 24 bacterias, 9 de las cuales no se han reportado en la literatura internacional. Se preparó un probiótico con estos microorganismos y se evaluó frente a descargas de Salmonella resultando un Factor de Protección (FP) >17.83. Se prepararon probióticos con las 24 bacterias identificadas y la flora aerobia obtenida de cada una de las granjas en estudio, se evaluó el FP y se obtuvieron resultados que mostraron un aumento promedio del FP de 54.95%. Los resultados indican que la eficiencia de un probiótico está dada por el tipo de flora aerobia y anaerobia que pueda contener.Palabras Clave: Probiótico; anaerobios; aerobios; Factor de Protección; aves adultas sanas.

Direito ao esquecimento versus liberdade de expressão
Authors: Landim de Souza Gisele
Published: July 2021

O direito ao esquecimento, reconhecido neste artigo como direito da personalidade, é matéria constitucional ainda pouco tratada no âmbito jurídico, mas que desperta muitas dúvidas e discussões. Isso ocorre porque o tema coloca o intérprete do direito diante de constante impasse entre o direito à privacidade e o direito à informação, à comunicação e à liberdade de expressão. Este artigo busca aprofundar o estudo desse assunto à luz do direito comparado e dos critérios de ponderação de valores. Para compreensão do tópico, foram analisadas decisões emblemáticas proferidas em cortes internacionais, bem como no Superior Tribunal de Justiça. Ao examinar em conjunto decisões nacionais e internacionais que versam sobre o mesmo pano de fundo, é possível notar aumento do reconhecimento do direito ao esquecimento nos ordenamentos jurídicos. Esse fator contribui para a evolução na jurisprudência sobre a temática, o que se faz indispensável, sobretudo em decorrência dos avanços da internet e do amplo acesso aos meios digitais pela população mundial. Como metodologia, foram utilizadas a análise documental e expositiva da jurisprudência internacional e nacional e a literatura sobre a técnica de ponderação. Na conclusão, sustenta-se a impossibilidade de sobreposição do direito ao esquecimento ou da liberdade de expressão e de informação sem a análise atenta do caso concreto, o que exige sensibilidade e atuação personalizada do aplicador do direito utilizando a ponderação de valores, de forma a não suprimir por completo qualquer dos direitos envolvidos.
O processo à luz de Kafka
Authors: Santos Adriana
Published: July 2021

O presente estudo, no campo do direito processual penal em articulação com a filosofia, analisa os reflexos do romance Der Process, de Franz Kafka, no procedimento criminal. Utiliza, na leitura e na interpretação do texto, o método fenomenológico, com auxílio de outras disciplinas, principalmente a história do direito. O percurso narrativo trata dos principais atores processuais em sentido estrito e aborda, no espectro amplo, os efeitos sociais do processo. Kafka descreve, de forma universal e atemporal, situações absurdas, em que eleva, por meio da literatura, a discussão ao patamar filosófico. A vivência pela personagem principal de deturpações e mazelas procedimentais de consequências trágicas expõe a fragilidade desse instrumento, carente de atividade humana para sua concretização. Fica demonstrado, ao final, que a maior das garantias consiste no fiel cumprimento do procedimento previsto. Em conclusão, com o objetivo de manter a paz social, o homem, diante de conflito de interesses, criou o processo como solução, cabendo à sociedade discutir incessantemente o sistema jurídico-processual e zelar pelo processo justo.
Potential Crucial Role of COX-1 and/or COX-2 Inhibition, NSAIDs or Aspirin Triggered Lipoxins and Resolvins in Amelioration of COVID-19 Mortality
Authors: Kelleni Mina
Published: July 2021

Aspirin has been recently suggested to be independently associated with
reduced risk of mechanical ventilation, ICU admission and in-hospital
mortality of COVID-19. However, we claim that the molecular
interpretation of these important results was not scientifically valid,
and we provide our academic interpretation that is also basing on our
real-life practice using non-steroidal anti-inflammatory drugs in
management of COVID-19 and we suggest that inhibition of COX-1 and/or
COX-2 enzymes might play a lifesaving role in COVID-19 management, and
we further discuss the potential of aspirin triggered lipoxins and
resolivns in the same context.

Favipiravir is one of the repurposed antiviral medications for the
treatment of SARS-CoV-2 infection. Since the dosing regimen is a
prominent factor for the success of the antiviral therapy, this
prospective observational study aimed to characterize the
pharmacokinetic characteristics of favipiravir in COVID-19 patients.
Adult patients (n=21) hospitalized for mild to moderate COVID-19 with a
positive RT-PCR test, and assigned for favipiravir treatment were
included. Favipiravir was administered for 5 days, with a loading dose
of 3200 mg and a 1200 mg/day maintenance dose. Serial blood samples were
collected on Day-2 and Day-4 of the therapy. Laboratory findings of the
patients and in-hospital mortality were assessed. Favipiravir
concentrations exhibited high variations and a significant decrease
during the treatment of COVID-19. The median favipiravir trough
concentration (C0-trough) on Day-2 was 21.26 µg/mL whereas it decreased
significantly to 1.61 µg/mL on Day-4, the area under the concentration
versus time curve decreased from 345.6 µg.h/mL to 108.6 µg.h/mL,
respectively. Gender seems significant to affect favipiravir
concentrations. Day-2-C0-trough of female patients was significantly
higher than male patients. Of the 5 patients that died, 4 were male with
a significant increase in ferritin levels from Day-0 to Day-5 compared
to surviving patients. In addition, there was a significant decrease in
D-dimer and CRP levels in the surviving patients. Our findings indicate
that favipiravir concentrations show significant changes during the
treatment of COVID-19. Therapeutic drug monitoring may best guide dose
adjustments in patients that do not respond to treatment with
favipiravir.

Authors: Eşki Aykut , Öztürk Gökçen Kartal , Turan Caner , Özgül Semiha , Gülen Figen , Demir Esen
Published: July 2021

Objective: To determine whether high-flow nasal cannula oxygen (HFNCO)
provided enhanced respiratory support in bronchiolitis than low-flow
oxygen (LFO). Methods: We conducted a prospective, randomized controlled
trial in children between 1-24 months diagnosed with moderate-to-severe
bronchiolitis requiring oxygen therapy. Participants received LFO via
face mask (6-10 L/min) or HFNCO (2 L*kg/min). Primary outcomes were the
time that heart rate (HR) and respiratory rate (RR) return to their
normal range for age and the time that baseline clinical respiratory
score (CRS) regress to a lower severity score. Secondary outcomes were
changes in HR, RR, and CRS over time, length of stay (LOS), duration of
oxygen requirement, treatment failure, and adverse event (AE). Results:
Eighty-seven children were enrolled (48 in LFO; 39 in HFNCO). The time
that HR and RR baseline values reached their normal range for age was
shorter in HFNCO therapy (2.0h [1.0-4.0] vs. 12.0h [2.0-24.0]
and 4.0 h [2.0-12.0] vs. 24.0 h [4.0-48.0], respectively;
P< .001); additionally, the improvement in CRS emerged more
quickly in children treated with HFNCO (2.0 h [1.0-4.0] vs. 4.0 h
[2.0-24.0]; P = .003). While the duration of oxygen requirement
(19.0 h [4.0-30.0] vs. 29.5 h [14.0-45.7]; P = .009) and
treatment failure (3% vs. 21%) was statistically lower in children who
received HFNCO, there were no differences in LOS and AE between groups.
Conclusion: HFNCO may provide enhanced respiratory support with a
notable improvement in HR, RR, and CRS than LFO. Comprehensive studies
are needed to assess the clinical efficacy of HFNCO therapy.

Nonlinear time-varying fatigue reliability analysis based on improved toughness exhaustion model
Authors: Gao Kai , Liu Gang
Published: July 2021

The state function based on fatigue accumulation model has a great
influence on accuracy of fatigue reliability analysis of components. A
nonlinear fatigue accumulation model considering the interaction of
loads is proposed in this paper. By introducing the square ratio of
front and back loads as the new load interaction factor into the
conventional toughness exhaustion model, thus it is improved to reflect
the load sequence and interaction effect simultaneously. Moreover, the
fatigue state function based on proposed model is constructed, which is
analyzed by the probability density evolution method. The time-varying
fatigue reliability curve is obtained by analyzing the generalized
density evolution equation. The proposed model are verified using four
experimental data, and results shows that the predication residual life
fraction such obtained is more accurate. And accuracy and efficiency of
the proposed time-varying fatigue reliability analysis method is
validated using multi-level loading experimental data.

Authors: Tuncay Burcu , Arı Selma , Arı Hasan , Camcı Sencer , Melek Mehmet , BOZAT Tahsin
Published: July 2021

Objective:The aim of this study is to evaluate the effect of iohexol as
a contrast agent on the anticoagulant activity of oral factor Xa
inhibitors. Methods:The study included 65 people who underwent contrast
computerized tomography (CT). Patients in group 1 were using rivaroxaban
(20 patients), patients in group 2 were using apixaban (20 patients),
patients in group 3 were using edoxaban (20 patients), and group 4 was
the control group (5 volunteers). Iohexol (60ml) was used as a contrast
agent. Two tubes were used to collect 2 ml of blood from the patients at
4 hours after the drug dose (rivaroxaban, apixaban, or edoxaban) and 1
hour after the contrast CT (CT was performed 3 hours after the drug was
taken). In the control group, at any time and 1 hour after contrast CT,
2 tubes of 2 ml of blood were collected. The anticoagulant properties of
rivaroxaban, apixaban, and edoxaban were evaluated using anti-factor Xa
levels. Results:The anti-factor Xa level was increased after using the
contrast agent in the rivaroxaban group (0.66±0.32U/ml vs.
0.67±0.32U/ml; p=0.01) and the edoxaban group (0.74±0.35 U/ml vs.
0.76±0.36 U/ml; p=0.006). However, there was no significant difference
in the apixaban group (0.66±0.33U/ml vs. 0.66±0.32U/ml; p=0.21) and
control group (0.02±0.01U/ml vs. 0.03±0.01U/ml; p=0.33). Conclusion:The
anticoagulant properties of rivaroxaban and edoxaban tended to increase
significantly, but there was no statistically significant difference in
the anticoagulant properties of apixaban with contrast agent. The
increasing is too small so that these laboratory results need to
validate with larger clinical trials(NCT04611386).

Background: Data regarding ventricular tachycardia (VT) or premature
ventricular complex (PVC) ablation following MVS is limited.) CA can be
challenging given perivalvular substrate in the setting of mitral
annuloplasty or prosthetic valves. Objective: To investigate the
characteristics, safety, and outcomes of radiofrequency catheter
ablation (CA) in patients with prior mitral valve surgery (MVS) and
ventricular arrhythmias (VA). Methods: We identified consecutive
patients with prior MVS who underwent CA for VT or PVC between January
2013- December 2018. We investigated the mechanism of arrhythmia,
ablation approach, peri-operative complications, and outcomes. Results:
In our cohort of 31 patients (77% men, mean age 62.3±10.8 years, left
ventricular ejection fraction 39.2±13.9%) with prior MVS underwent CA
(16 VT; 15 PVC). Access to the left ventricle was via transseptal
approach in 17 patients, and a retrograde aortic approach was used in 13
patients. A combined transseptal and retrograde aortic approach was used
in one patient, and a percutaneous epicardial approach was combined with
trans-septal approach in 1patient. Heterogenous scar regions were
present in 94% of VT patients and scar-related reentry was the dominant
mechanism of VT. Clinical VA substrates involved the peri-mitral area in
6 patients with VT and 5 patients with PVC ablation. No
procedure-related complications were reported. The overall
recurrence-free rate at 1-year was 72.2%; 67% in the VT group and 78%
in the PVC group. No arrhythmia-related death was documented on
long-term follow-up. Conclusion: CA of VAs can be performed safely and
effectively in patients with MVS

Published: July 2021

The use of electronic cigarettes (e-cigarette) and vaping devices
started as a potential aid for cessation and reducing the harmful
consequences of cigarette smoking, mainly in the adult population. Today
e-cigarette use is highly increasing in vulnerable populations,
especially young and pregnant women, due to the misconception of its
harmless use. Despite the growing acknowledgment in e-cigarette as a
potential harmful device, and due to mixed information found concerning
its beneficial aid for smokers, along with an insufficient clinical
study done in human models, it is important to further evaluate the
possible benefits and risks of non-combusting, vaping nicotine or
non-nicotine delivery devices. In this review we tried to summarize the
latest updated information found in the literature, concentrating mainly
in the variety of adverse effects of e-cigarette use and its
contribution for recent and future health concerns.

Published: July 2021

This research was conducted to explore the management strategy of LPD in Pedawa Customary Village in suppressing NPLs. The research method applied in this research was descriptive qualitative method. Data were obtained through in-depth interviews, observation and study of documents which were then analyzed byanalysis interactive model from Milesand Huberman (1967). The results show that the occurrence of NPL problems in LPD decreases after the implementation of nunda tetegenan sanctions as an ancient tradition in Pedawa Customary Village. Nunda tetegenan consists of 3 levels, namely social sanctions, customary sanctions and witness sanctions. This nunda tetegenan sanction does not prohibit village manners from carrying out their obligations as religious people to carry out their yad activities, but rather delaying the right manners to acquire customary witnesses, postponing negen kena-kenaan banten piodalan but still being able to offer other offerings, and delaying the right to obtain services from Customary Villages.

In order to get the maximum income from Motor Vehicle Tax, it is necessary to have compliance from the taxpayer itself. The level of taxpayer compliance can be affected by the existence of tax sanctions as a preventive effort to curb and deter taxpayers and tax offenders. However, large accumulated tax sanctions often make people with limited income not paying their obligations. Therefore, this study aimed to investigate the effectiveness of tax sanctions on taxpayer compliance with taxpayer income levels as a moderating variable. This research was a quantitative study which used multiple linear regression analysis method with 100 individual taxpayers as the sample. The data were collected using a closed-ended questionnaire with Likert scale. The results show that motor vehicle tax sanctions provide 12.4% effectiveness on taxpayer compliance, while the income level of taxpayers is not a moderating variable that affects the relationship between tax sanctions and taxpayer compliance.
