Geometric and spectral properties of causal maps
Authors: Curien Nicolas , Hutchcroft Tom , Nachmias Asaf
Published: August 2020

We study the random planar map obtained from a critical, finite variance, Galton–Watson plane tree by adding the horizontal connections between successive vertices at each level. This random graph is closely related to the well-known
causal dynamical triangulation
that was introduced by Ambjørn and Loll and has been studied extensively by physicists. We prove that the horizontal distances in the graph are smaller than the vertical distances, but only by a subpolynomial factor: The diameter of the set of vertices at level

n

is both

o(n)

and

n^{1-o(1)}

. This enables us to prove that the spectral dimension of the infinite version of the graph is almost surely equal to 2, and consequently the random walk is diffusive almost surely. We also initiate an investigation of the case in which the offspring distribution is critical and belongs to the domain of attraction of an

\alpha

-stable law for

\alpha \in (1,2)

, for which our understanding is much less complete.
Juan Luis Vives (1492–1540) in njegov priročnik De institutione feminae Christianae
Authors: Ješovnik Martina , Movrin David
Published: August 2020

Med humanisti, kot so Tomaž More, Erazem Rotterdamski ter Guillaume Budé, se v poljudnih prikazih redko znajde Juan Luis Vives, čeprav je po njihovem mnenju veljal za vodilnega misleca svojega časa. Toda tudi to se počasi spreminja, po zaslugi nemških raziskovalcev pedagogike in empirične psihologije se je v 19. stoletju zanimanje zanj spet prebudilo in slednjič dobilo podobo v doslej najobsežnejši biografiji, ki jo je leta 1970 objavil Carlos Noreña. Čeprav se še zgodi, da Vives ostane spregledan celo v kateri od preglednih razprav o humanizmu, je v zadnjih desetletjih zanimanje za tega humanista izrazito naraslo. Članek ponuja vpogled v življenje tega humanista, njegov čas in opus. Osrediščen je na vzgojni priročnik za ženske z naslovom De institutione feminae christianae, napisan za hčer takratnega angleškega monarha Henrika VIII. in njegove prve žene Katarine Aragonske.
Aproximaciones a un nuevo perfil feminicida: una mirada a los cambios y las transiciones
Authors: Barboza Tello Marco Leon Felipe , Montag Doreen
Published: August 2020

Desde una perspectiva comprehensiva y contextualizada se realiza un abordaje inicial del confinamiento a raíz de la pandemia, y de sus implicancias en materia de violencia contra las mujeres, para luego describir las masculinidades en proceso de transformación, indicando que los maltratadores ocasionales e imprevisibles, los espacios citadinos, las masculinidades melodramáticas, la reputación masculina y la agencia feminicida en ascenso de las ex parejas, son rasgos prevalecientes de los actuales feminicidios, y por ello deberían ser considerados en la elaboración de un perfil feminicida.
Grandes religiones y nuevos movimientos religiosos ante la pandemia de covid-19
Authors: De León Azcárate Juan Luis
Published: August 2020

Desde el reconocimiento de que la dimensión religiosa/espiritual ayuda a la persona a dar sentido a su vida y a afrontar las situaciones de crisis, tal como parece refrendar una abundante literatura del campo de las ciencias de la salud, este artículo describe y analiza algunas de las respuestas más significativas dadas por las instituciones y líderes de las grandes religiones y de algunos nuevos movimientos religiosos ante la actual pandemia provocada por el COVID-19. Los diversos medios de comunicación y las páginas web oficiales han informado de cuál ha sido su respuesta. El repaso de estas fuentes y evidencias sugiere que, en líneas generales, los líderes e instituciones de las grandes tradiciones religiosas han seguido las recomendaciones de la Organización Mundial de la Salud y de las autoridades sanitarias, lo que ha facilitado que miles de millones de creyentes en todo el mundo tuvieran un comportamiento responsable ante la pandemia. Además, han propiciado campañas de solidaridad con los colectivos más vulnerables. Sin embargo, también debe reconocerse que, aunque minoritarias si se tiene en cuenta su número de seguidores, hay formas de religiosidad y espiritualidad que, especialmente al comienzo de la pandemia, ofrecieron pautas negativas de afrontamiento que favorecieron la propagación del virus.

Authors: KOKOÇ Melda , ERSÖZ Süleyman
Published: August 2020

Under 21st century conditions, engineering education should focus not only on professional skills such as design, manufacture, and maintenance but also on soft skills, which play an important role in supporting career advancements, such as communication, interpersonal relations, and teamwork. In other words, it is an obligation for engineers to be competent in their own discipline. In addition to its own discipline, it will be a plus to be able to work with individuals from other disciplines and to exchange information seamlessly in the work environment. In this context, graduation as a T-shaped engineer with sensitive skills that will enable this acquisition will be prominent in career planning. The aim of this study is to introduce the T-shaped term that is not yet widespread in Turkey and to investigate soft skills forming the horizontal component of the T-shaped engineer. In line with the purpose of the research, studies on the soft skills that engineers must acquire, the program outcomes determined by the accreditation boards, and job ads are analyzed. In addition to the determination of soft skills, suggestions compiled from the literature are presented for higher education institutions to train their students as T-shaped engineers.

Authors: Barros Alves Bruno Adriano
Published: August 2020

O ano de 1837 em Pernambuco marca a subida de Francisco do Rego Barros (Barão da Boa Vista) ao poder e junto a ele o seu projeto político de modernizar a província via melhoramentos urbanos. Nesse momento a historiografia destaca que diversas obras foram projetadas ou orçadas principalmente na capital e diversos trabalhadores estrangeiros foram contratados. Contudo, a proposta do Barão de reformulação da Repartição de Obras Públicas (ROP) não foi bem aceita por todos, servindo posteriormente de munição para os opositores e impactando de maneira significante nas eleições e movimentos insurrecionais que se sucederam. Nesse sentido, o presente artigo tem por objetivo analisar alguns dos embates políticos entre conservadores, governistas e liberais praieiros em torno da ROP da Província de Pernambuco presentes no Diário de Pernambuco e no Diário Novo.

INFLUENCE OF NANOPARTICLES OF $ \mathrm{CuO} $ ON THE STABILITY AND CONDUCTIVITY OF BLM
Authors: Torosyan A.L. , Ananyan G.V. , Arakelyan V.B.
Published: August 2020

This study aims to provide arguments for an increase in the stability of bilayer lipid membranes (BLM) in an electrical field in presence of $ \mathrm{CuO} $ nanoparticles. Moreover, the sustainability of BLM becomes more stable with increasing of nanoparticles concentration. It is shown that an increase in the stability of BLM in an electrical field is mainly due to an increase in the coefficient of linear tension of the edge of a pore, which is forming in BLM. It is shown as well, that the presence of nanoparticles of $ \mathrm{CuO} $ in the solution surrounding BLM leads to a decrease in the conductivity of the BLM.

Published: August 2020

Microwave stripline resonators of rectangular and double rectangular shapes for non-invasive sensing have been designed and investigated experimentally and numerically. The resonator of single rectangular shape has had a resonance at about 4.32 GHz for $ S_{21} $ and the resonator of double rectangular shape has had resonances at about 3.5 GHz for $ S_{21} $ and 5.85 GHz for $ S_{11} $. The simulation results for the sensitivity of the single rectangular and double rectangular resonators were -0.023 dB/(mg/dL) (glucose concentration) and 0.0143 dB/(mg/dL) (NaCl concentration), respectively. The electromagnetic field distribution of the resonators was visualized and compared using computer simulation software HFSS. The obtained data have shown the accuracy of resonators as a non-invasive sensor for biophysical applications.
SOME RESULTS ON REGULAR EXPRESSIONS FOR MULTITAPE FINITE AUTOMATA
Authors: Grigoryan T.A.
Published: August 2020

We consider sets of word tuples accepted by multitape finite automata. We use the known notation for regular expressions that describes languages accepted by one-tape automata. Nevertheless, the interpretation of the "concatenation" operation is different in this case. The algebra of events for multitape finite automata is defined in the same way as for one-tape automata. It is shown that the introduced algebra is a Kleene algebra. It is also, shown that some known results for the algebra of events accepted by one-tape finite automata are valid in this case too.
TRANSFER OF LOADS FROM A FINITE NUMBER OF ELASTIC OVERLAYS WITH FINITE LENGTHS TO AN ELASTIC STRIP THROUGH ADHESIVE SHEAR LAYERS
Authors: Kerobyan A.V.
Published: August 2020

This article deals with the problem of an elastic infinite strip, which is strengthened along its free boundary by a finite number of finite overlays with different elastic characteristics and small constant thicknesses. The interaction between the strip and the overlays is mediated by adhesive shear layers. The overlays are deformed under the action of horizontal forces. The problem of determination of unknown stresses acting between the strip and overlays are reduced to a system of Fredholm integral equations of the second kind for a finite number of unknown functions defined on different finite intervals. It is shown that in the certain domain of variation of the characteristic parameter of the problem this system of integral equations in Banach space may be solved by the method of successive approximations. Particular cases are discussed and the character and behaviour of unknown shear stresses are investigated.

INFLUENCE OF ZINC OXIDE NANOPARTICLES ON BILAYER LIPID MEMBRANE PROPERTIES
Authors: Torosyan A.L. , Ananyan G.V. , Arakelyan V.B.
Published: August 2020

The effect of zinc oxide nanoparticles ($ \mathrm{ZnO} $) on the stability and conductivity of the bilayer lipid membrane (BLM) in solution was studied. It has been shown that $ \mathrm{ZnO} $ nanoparticles increase the stability of BLM in an electric field, and BLM becomes more stable with increasing their concentration. The increase in the stability of BLM in an electrical field is mainly due to the increase in the coefficient of linear tension of the pore edge, which is forming in BLM. It is also shown, that the presence of $ \mathrm{ZnO} $ nanoparticles in the solution surrounding BLM leads to a decrease in the BLM conductivity.

The key factors affecting the severity of COVID-19 include advanced age and respiratory failure requiring mechanical ventilation (MV). Mortality rates estimated for mechanically ventilated patients with SARS-CoV-2-induced respiratory failure are 76.4% in the 18-65 age group and 97.2% in individuals over 65 years. At present, extracorporeal membrane oxygenation (ECMO) remains a life-saving method of choice. It is essentially a lung bypass system for direct oxygenation of the blood. It is an invasive and costly procedure performed only at specialized medical care facilities. China, USA, Germany, France and Israel have already launched large-scale research and clinical studies of non-invasive approaches to improving the efficacy of oxygen therapy in patients with complicated viral pneumonia, such as hyperbaric oxygen therapy (HBOT). HBOT is a well-established treatment for anaerobic and aerobic infections accompanied by soft tissue necrosis, carbon monoxide poisoning, stubborn wounds, including non-healing diabetic ulcers, complications of radiation therapy, stroke sequelae, brain injuries, decompression sickness, and other conditions. The use of HBTO in patients with viral infection, pulmonary edema and pneumonia is supported by the laws of physics and clinical/physiological effects in response to the exposure of elevated air pressure and hyperoxic environment.  This review provides rationale for using hyperbaric oxygenation therapy in patients with SARS-CoV-2-induced viral pneumonia and presents the first data on the beneficial effects of HBTO in Chinese patients with COVID-19 complications.

Weeds are undesirable plants because they can compete with the oil palm. Weed growth can reduce the production of bunches by 20%. Weeds are not only due to competition against nutrients but also produce allelopathic substances that are toxic to oil palm. Inventory and find out the dominance of weed species is needed in the management of effective weed control. The study aims to determine the diversity of weeds in different areas of planting year. This study used a sampling method carried out on two mature areas (18 years and 8 years) and an immature area (1 year), with the direct observation method. Every planting area is made of 2 large plots with a size of 20 m x 60 m at interrow of palm, then inside there are made 6 small plots with a size of 2 x 2 m. Data were analyzed with SDR (Summed Dominance Ratio) value to determine the dominant weed species. The diversity of weeds from each area is varied, there are 29 species of weeds and 20 families, nevertheless, there are 5 species of weeds found in all areas of study; O. nodusa, Poaceae; C. kyllingia, Cyperaceae; A. comressus, Poaceae; P. Niruri, Phyllanthaceae; A. spinous, Amaranthaceae. The dominant weeds in the immature area are E. indica, Poaceae while in the mature areas are O. nodosa, Poaceae.

One of the goals of the state as mandated by the Constitution NRI Year 1945 is to promote the general welfare. As mandated by the constitution, the government is obliged to meet the objectives of the country. In addition Article 28 paragraph 1 of the Constitution NRI 1945 also gives the right to every person to live in physical and spiritual prosperity, as a human right. One form of the welfare of society is the availability of infrastructure and facilities to support each activity. The realization of infrastructure facilities such example is building. On one hand the government does not have the funds to provide the building, but the government owns the land. Therefore, the government can invite investors and cooperation for the procurement of the building by using the System Build, Operate and Transfer

Women in the National Academy of Medicine of Venezuela. Recent advances towards gender equality, Goal 5 of the UN 2030 Agenda for Sustainable Development
Authors: Cruz Lilia
Published: August 2020

Para conocer cómo la Academia Nacional de Medicina de Venezuela (ANM) avanza para lograr la igualdad de género entre sus miembros, establecida como meta No 5 en la Agenda 2030 de la Organización de las Naciones Unidas (ONU) para el Desarrollo Sostenible, realizamos un análisis cuantitativo del proceso de incorporación de la mujer a la institución y a sus órganos de dirección. Dos lapsos fueron comparados: los primeros 110,5 años, desde la fundación de la Academia en abril de 1904 hasta el 12 de noviembre de 2014, y los últimos 5,5 años, entre el 13 de noviembre de 2014 y el 16 de junio de 2020. Durante los 110,5 primeros años, 472 hombres y 14 mujeres (2,9 %) fueron elegidos. En los últimos 5,5 años fueron incorporados 17 hombres y 7 mujeres (29,2 %). La representación porcentual de la mujer en la ANM en la actualidad es la siguiente: Individuos de Número (IN): 13,5 %, Miembros Correspondientes Nacionales (MCN): 28 %, Miembros Correspondientes Extranjeros (MCE): 3 %, Invitados de Cortesía: 24 %. En la Junta Directiva electa el 2 de junio de 2020 para el bienio 2020-2022, hay 2 mujeres entre 5 personas (40 %): vicepresidente (Isis Nezer) y tesorero (Lilia Cruz) mientras que en el bienio precedente hubo una sola mujer. Ha habido progreso considerable desde 1981, cuando una mujer fue electa por primera vez en la ANM, especialmente en los últimos 5,5 años, pero la corporación se encuentra muy lejos de lograr la igualdad de género. Es necesario trabajar específicamente para alcanzar el objetivo propuesto por la ONU.

Published: August 2020

COVID-19 es una enfermedad respiratoria aguda,causada por un nuevo coronavirus SARS-CoV-2. El 11 de marzo de 2020, la OMS declaró al COVID-10 como pandemia. La rapidez con la cual se ha abordado la pandemia de COVID-19 ha sido posible gracias a la producción de conocimiento científico con publicación inmediata, y resultados en tiempo real y comunicando por redes sociales. La fisiopatología de COVID-19 es compleja y en la actualidad no se comprende plenamente. En este sentido, en el presente estudio analizamos distintos aspectos relacionados con la entrada del SARS-Cov-2 a las células del huésped humano a través de su unión al receptor de la ACE2 (por sus siglas en inglés, angiotensin converting enzyme 2), la respuesta inflamatoria exacerbada o tormenta de citocinas y factores que contribuyen a un mayor contagio por personas infectadas denominadas supertransmisores. Tópicos que son esenciales para comprender y afrontar la COVID-19.
La glomerulonefritis aguda pos-estreptocóccica en América Central, América del Sur y países del Caribe
Authors: Rodriguez-Iturbe Bernardo
Published: August 2020

Este trabajo analiza la glomerulonefritis aguda posestreptocóccica (GNAPE) en las regiones de América Central, América del Sur y región del Caribe. La incidencia de la enfermedad en general parece haber disminuido pero los datos revelan resultados muy variables. Las epidemias de GNAPE se han descrito en varios países y los reportes de casos esporádicos y del pronóstico a largo plazo son aislados. La información disponible es escasa y fragmentaria y por ello es importante diseñar estrategias que permitan detectar la aparición de epidemias, identificar el subtipo del esreptococo causal, la incidencia de la GNAPE en las consultas y emergencias de nefrología pediátrica y el pronóstico a largo plazo de la enfermedad.

Introducción: La inactividad física es un problema de salud pública asociado a enfermedades crónicas no transmisibles. Determinar la prevalencia general y por esferas de inactividad física, y su asociación con factores cardiometabólicos. Métodos: Estudio transversal que incluyó 2 230 individuos adultos de ambos sexos de la ciudad de Maracaibo. Para la evaluación de la actividad física se aplicó la versión larga del Cuestionario internacional de actividad física, definiéndose la inactividad física como <600 MET-minutos/semana, se realizó un análisis de regresión logística multivariante para cada dominio. Resultados: La mayor prevalencia de inactividad física fue en la esfera de transporte (80,3 %), seguida de la esfera de trabajo (79,9 %), ocio (76,8 %) y hogar (47,9 %). En las 3 primeras esferas la inactividad física fue más frecuente en mujeres y la mayoría de sujetos fueron inactivos en 3 o 4 esferas simultáneamente. Las variables asociadas con inactividad física en ocio fueron el sexo femenino, edad >30 años, grupo étnico arábigo-asiático y estatus de exfumador; en la esfera transporte fueron el sexo femenino, sobrepeso y obesidad; en la esfera trabajo fueron el sexo femenino, edad ≥50 años, estatus educativo de secundaria, condición laboral de empleado y diabetes mellitus tipo 2; en la esfera hogar fueron el sexo masculino, estrato socioeconómico II-IV y la condición laboral de empleado. Conclusión: Existe una alta prevalencia de inactividad física en los habitantes de la ciudad de Maracaibo, por lo que es necesaria la promoción del ejercicio.

Authors: Álvarez-Maestre Annie Julieth
Published: August 2020

El estrés como síndrome psicopatológico muestra una prevalencia entre 1 % y 2 % de la población mundial. Las condiciones normales de la vida diaria pueden convertirse en un agente amenazante cuando el individuo no tiene los recursos psicológicos y físicos para responder a la situación. El estrés vocacional es la respuesta de tensión e incomodidad a los estímulos y demandas derivados del desarrollo vocacional. Esto incluye la decisión vocacional, la pérdida del empleo, la percepción de autoeficacia, las tensiones entre el estudio, el trabajo y la familia, entre otros. En este artículo de investigación, se utilizó la metodología documental de investigación de revisión narrativa; como resultado se mostró la relevancia que una orientación profesional efectiva se relaciona como una estrategia preventiva a la posibilidad de desarrollar distrés profesional. Lograr que el proceso de orientación vocacional se convierta en el contexto en el que se proporciona al individuo un repertorio de herramientas cognitivo-conductuales esenciales para la toma de decisiones, la resiliencia, la autoestima, la autoeficacia y la madurez vocacional, las cuales se establecen como factores de protección contra el riesgo de enfermedades mentales y psicofisiológicas. Este escrito contribuye a la prevención del trastorno mental de posible aparición en las dimensiones del estudio y el trabajo, entendiendo sus beneficios para la mitigación de los factores de riesgo, de acuerdo con las recomendaciones de la Organización Mundial de la Salud.

La promoción y la protección de la salud son esenciales para el bienestar humano y para un desarrollo socioeconómico sostenido. Así lo reconocieron hace más de 30 años los firmantes de la Declaración de Alma-Ata, Kazajstán, quienes señalaron que la Salud para Todos contribuiría a mejorar tanto la calidad de vida como la paz y la seguridad en el mundo. En este trabajo se registra como los países de América latina y Europa invierten sus sistemas de financiación para avanzar con mayor rapidez hacia la cobertura universal donde se muestran los montos totales de recaudación para el sistema, en el cual está incluida la contribución de las empresas, los trabajadores y el estado. Los sistemas de seguridad social de los Estados deben ofrecer cobertura para las siguientes nueve ramas principales de la seguridad social: atención de salud, enfermedad, vejez, desempleo, accidentes laborales, prestaciones familiares, maternidad, discapacidad, sobrevivientes y huérfanos. De estas áreas, en el presente trabajo se discute lo referente a vejez, invalidez y sobrevivientes; salud y maternidad; accidentes de trabajo; desempleo y prestaciones familiares.

La inflamación y la hipercolesterolemia son considerados factores de riesgo involucrados en la patogénesis de las enfermedades cardiovasculares. La grelina y sus receptores están presentes en el miocardio y la vasculatura, donde ejercen funciones cardioprotectoras y antiinflamatorias. El péptido C es un producto de la proinsulina que juega un papel fisiológico en diferentes tipos de células y tiene propiedades pro y antiinflamatorias. Sin embargo, el mecanismo que involucra a estos péptidos en condiciones de inflamación de bajo grado es complejo y aún no se conoce bien. En el presente estudio, evaluamos los niveles plasmáticos de grelina, péptido C, mediadores inflamatorios y proteína C reactiva (PCR) en un grupo de sujetos voluntarios venezolanos hipercolesterolémicos y con sobrepeso. Los sujetos se dividieron en dos grupos según su colesterol total: control e hipercolesterolémicos. Después del ayuno nocturno, se determinaron parámetros clínicos en muestras de sangre venosa: glicemia en ayunas, colesterol total, HDLc, triglicéridos y PCR. Los niveles de citocinas, quimiocinas y factores de crecimiento se evaluaron mediante análisis multiplex de microesferas. Nuestros hallazgos demostraron que los pacientes hipercolesterolémicos muestran niveles significativamente más altos de PCR, grelina y péptido C. El colesterol se correlacionó positivamente con IL-2, IL-8, IFN-γ, eotaxina, grelina, VEGF, MCP-1, TNF-α, bFGF, G-CSF, PCR y péptido C. La grelina se correlacionó negativamente con IL-8, IL-4, IL- 6, IL-17 y RANTES. El péptido C se correlacionó positivamente con eotaxina, y INF-γ, y marcadores de diabetes como insulina, leptina, PAI-1, resistina, grelina, visfatina, adiponectina y adipsina. Mientras, el péptido C se correlacionó negativamente con IL-4, IL-5, IL-7, IL-10, e IL-13. Estos datos indican que en la población venezolana estudiada, en los pacientes hipercolesterolémicos subyacen alteraciones en grelina, péptido C, citocinas inflamatorias, moléculas de adhesión, quimiocinas y marcadores de diabetes.
