Authors: Racedo Niebles Francisco Juan , Pérez Gamboa Alfredo , Pérez Panza Juan Camilo
Published: September 2021

An experimental and theoretical study of the non-linear optical properties of two derivatives of 1-Aryl-3-(4-Methoxyphenyl)-5-(Benzo(d)(1,3)Dioxol-5-yl)-2H-pirazolines was carried out. Pyrazolines based on the excitation power of the laser, to establish its potential use in the photonics industry 1. These compounds already synthesized and characterized by UV-vis spectroscopy, in THF as a solvent, were submitted to readings in the Z-scan system to determine different optical parameters, such as the non-linear refractive index (η2), the absorption coefficient nonlinear (β) and third order electronic susceptibility (X (3)). For these measurements, a Cd Nd: YAG laser emitting at 532 nm, a focus of a 10 cm lens, a 1 mm iris and a cell with a length of 1 mm were used; To support the experimental results, quantum mechanical calculations were performed with the calculation level M06-2X / 6-31 G (2d). This study allowed to correlate the molecular design with the optical properties.
A comprehensive examination of ACE-2 receptor and prediction of spike glycoprotein and ACE-2 interaction based on in silico analysis of ACE-2 receptor
Authors: Özgentürk Nehir Özdemir , Aktaş EMRE
Published: September 2021

ACE-2 receptor plays a vital role not only in the SARS-CoV-induced
epidemic but also in some diseases. Studies have been carried out on the
interactions of ACE-2- SARS-CoV proteins. However, comprehensive
research has not been conducted on ACE2 protein by using bioinformatic
tools. The present study especially two places, G104 and L108 points,
which are effective in protecting the structure of the ACE-2 protein,
play a critical role in the biological functioning of this protein, and
play an essential role in determining the chemical-physical properties
of this protein, and play a crucial role for ACE-2 protein-SARS CoV
surface glycoprotein, were determined. It was also found that the G104
and L108 regions were more prone to possible mutations or deletions than
the other ACE-2 protein regions. Moreover, it was determined that all
possible mutations or deletions in these regions affect the
chemical-physical properties, biological functions, and structure of the
ACE-2 protein. Having a negative GRAVY value, one transmembrane helix, a
significant molecular weight, a long-estimated half-life as well as most
having unstable are results of G104 and L108 points mutations or
deletions. Finally, it was determined that LQQNGSSVLS, which belong to
the ACE-2 protein, may play an active role in binding the spike protein
of SARS-CoV. All possible docking score results were estimated. It is
thought that this study will bring a different perspective to ACE-2
_SARS-CoV interaction and other diseases in which ACE-2 plays an
important role and will also be an essential resource for studies on
ACE-2 protein.

Published: September 2021

El cacao (Theobroma cacao L.) es uno de los cultivos representativos del departamento del Meta (Colombia), cuyos granos son aprovechados en la industria chocolatera. El almacenamiento es un punto de control ya que en él pueden presentarse fenómenos de deterioro que afectan su calidad. Durante este ocurren variaciones de temperatura y humedad relativa que provocan pérdidas en las propiedades fisicoquímicas y organolépticas de los granos a causa de su capacidad higroscópica, facilitando el crecimiento de hongos. Por tanto, en este trabajo se pretendió determinar condiciones de temperatura y humedad relativa con el fin de buscar prolongar la vida útil de granos de cacao deshidratado durante su periodo de almacenamiento. Para ello se construyeron isotermas de adsorción a temperaturas de 25, 30 y 35 °C para el rango de αw entre 0.146 y 0.891. Donde se obtuvieron isotermas de tipo II por tener forma de “S” o por ser tipo sigmoidea. Estas se ajustaron a modelos matemáticos comúnmente aplicados en alimentos. El ajuste de los modelos se evaluó con aquel que presentara una raíz del error cuadrado medio (RMSE) más aceptable y un coeficiente de correlación (R2) cercano a 1. En función de los cuales, se observó que el modelo propuesto por Smith presentó el mejor ajuste de los datos experimentales. Los resultados obtenidos permitieron proponer que a condiciones de humedad relativa superior al 51.4% e igual y/o inferior al 58.9% y a temperatura de 25°C, se prolongaría la vida útil de los granos de cacao deshidratados manteniendo estándares de calidad durante el proceso de almacenamiento.
Women's Age of First Exposure to Internet Pornography Predicts Sexual Victimization

Increases in the availability and accessibility of Internet pornography have led growing numbers of children to become consumers of sexually explicit media. Research has identified negative behavioral and attitudinal outcomes associated with Internet pornography use in childhood and adolescence, but few studies have examined sexual victimization as a correlate. The current study aimed to examine the association between age of first Internet pornography exposure and sexual victimization. Data from 154 undergraduate women yielded several important findings. Women who viewed Internet pornography unintentionally at a younger age reported more sexual victimization. Specifically, compared to women who were first unintentionally exposed to Internet pornography at age 14 or older, women with unintentional first Internet pornography exposure before the age of 14 reported more childhood sexual abuse, sexual abuse in adulthood, and more instances of sexual coercion and aggression. Women with younger age of unintentional Internet pornography exposure also reported more interpersonal sexual objectification than women who had never viewed Internet pornography at all. Age of first intentional exposure to Internet pornography was not related to women’s self-reported experiences of objectification, although this may be because women’s intentional exposure tended to happen at older ages. Overall, the results of this study suggest that women’s unintentional Internet pornography exposure at a young age may contribute to a potentially harmful sexual socialization. Early Internet pornography exposure in childhood should be considered a potential risk factor for women’s sexual victimization.
Folkeretten og 11. september – et vannskille?
Authors: Hellestveit Cecilie , Nystuen Gro
Published: September 2021

11. september-angrepene og USAs svar utfordret folkerettens regler. Basert på et argument om selvforsvar, lanserte Bush-administrasjonen en global krig mot terrorisme, med fangeleirer, bruk av tortur og utenomrettslige henrettelser. Essayet gir en oversikt over tre folkerettslige hovedproblemstillinger som oppsto i årene etter 2001. Folkerettens regimer om samarbeid for å motarbeide terror var for svake, FN-pakten gav lite klare regler om staters selvforsvarsrett mot ikke-statlige aktører på fremmed jord, og angrepene utfordret folkerettens todeling mellom krig og rettshåndhevelse (humanitærrett og menneskerettigheter). Essayet gjør opp status for hvordan folkeretten utviklet seg på disse områdene etter 2001, og tar stilling til om dette gir grunnlag for å betegne 11. september som et vannskille i folkeretten.
Abstract in English:International Law and 9/11 – a Watershed?The 9/11 attacks and the US global response was a challenge to international law. Based on an argument of self-defense, the Bush-administration launched a global war on terror, established prison-camps, opened up for torture and engaged in targeted killings. The essay provides an overview of the main challenges that arose after 9/11 from the perspective of international law. The international regime for prevention of terrorism was weak, it was unclear to what extent the UN Charter provided states with an independent right to self-defense against non-state actors in foreign states, and the attacks challenged the dichotomy between war and crime (humanitarian law and human rights). The essay analyses how these areas of international law have evolved after 2001 and concludes by assessing whether 9/11 can be deemed a watershed in the development of international law.
Analyzing Optimism Bias, Risk Perception and Behavioral Outcomes in the Context of COVID-19 in the Autonomous University of Queretaro’s Community: A Pilot Study
Authors: Roman Orozco Oscar San
Published: September 2021

Background: The coronavirus pandemic is a major health crisis that presents new and unprecedented challenges, including challenging how individuals deal with risk. Individuals’ perceptions and behavioral responses to the outbreak are essential determinants of the spread of COVID-19. Understanding individuals’ perceived risk provides insight into their engagement in preventive behavior. Optimism bias plays a significant role in the perceptions of those who underestimate their risk compared to others with similar risk. Objective: This pilot study aims to determine the level of optimism bias, risk perception and risk response for COVID-19 among a convenience sample from the UAQ community - and to analyze the relationship among behavioral outcomes and information seeking intentions with the previous indicators - in order to propose a model of behavior of residents of Queretaro that will be tested in a further study. Methods: This study used a cross-sectional survey designed on the Qualtrics platform. The survey was distributed to the UAQ community through an online platform: The Universidad Autonoma de Queretaro’s (UAQ) official Facebook page. Out of 1048 responses received, a total of 810 valid responses were included in the multivariate linear regression analyses to determine the relationship between optimism bias, risk perception, information seeking intentions, and behavioral outcomes. Results: Results showed that among this population, of which the majority had no previous conditions and did not contract COVID-19, there was a low level of optimism bias. The low levels of optimism bias are associated with a higher level of risk perception. These findings were also associated with high levels of information seeking intentions, specifically receiving information from relatives with public health or medical knowledge. The results show that among this population, fear was a significant determinant impacting safer decision-making and efforts to reduce exposure. Age and education of this population are also important factors to consider when analyzing the results of this study. Conclusion: The study findings indicate that decreased optimism bias is associated with increased risk perception which strengthens individuals’ motivation to take precautionary measures and preventive action during the COVID-19 pandemic. Further research is needed to expand on the theory and test the proposed model as well as inform policy decisions and public health campaigns to stop the spread of COVID-19.

Authors: Reksodiputro Mirta Hediyati , Koento Trimartani , Manunggal Dwi Wahyu
Published: September 2021

Auricular defects must be treated early and properly because they may interfere with facial symmetry. Retroauricular skin is an ideal flap source for a non-reduction reconstruction procedure of the upper, middle, and lower auricular defects. Auricular reconstruction aims to achieve good anthropometric and aesthetic ear unit. The purpose of this case report is to present a reconstruction of auricular defects using the rectroauricular flap that results in a favorable aesthetic and normal anthropometric dimensions of the auricular. We report a case of auricular defect caused by post-excision of keloid located in the helical and antithetical area of the middle third of the right auricular, using a retroauricular flap. Normal values of the auricular’s anthropometric measurements were achieved, followed by a complete aesthetic ear unit. Retroauricular flaps are suitable for reconstructing partial auricle defects in the helical rim, temporal area, and conchae.
Keywords: auricular defect, retroauricular flap, aesthetic ear unit, auricular anthropometry.

Published: September 2021

IntroductionAssisted reproductive technologies (ART), such as in-vitro fertilisation (IVF), have revolutionised the treatment of infertility, with an estimated 8 million babies born worldwide. However, the long-term health outcomes for women and their offspring remain an area of concern. Linking IVF treatment data to long-term health data is the most efficient method for assessing such outcomes.
ObjectivesTo describe the creation and performance of a bespoke population-based data linkage of an ART clinical quality registry to state-based and national administrative datasets.
MethodsThe linked dataset was created by deterministically and probabilistically linking the Australia and New Zealand Assisted Reproduction Database (ANZARD) to New South Wales (NSW) and Australian Capital Territory (ACT) administrative datasets (performed by NSW Centre for Health Record Linkage (CHeReL)) and to national claims datasets (performed by Australian Institute of Health and Welfare (AIHW)). The CHeReL's Master Linkage Key (MLK) was used as a bridge between ANZARD's partially identifiable patient data (statistical linkage key) and NSW and ACT administrative datasets. CHeReL then provided personal identifiers to the AIHW to obtain national content data. The results of the linkage were reported, and concordance between births recorded in ANZARD and perinatal data collections (PDCs) was evaluated.
ResultsOf the 62,833 women who had ART treatment in NSW or ACT, 60,419 could be linked to the CHeReL MLK (linkage rate: 96.2%). A reconciliation of ANZARD-recorded births among NSW residents found that 94.2% (95% CI: 93.9--94.4%) of births were also recorded in state/territory-based PDCs. A high concordance was found in plurality status and birth outcome (≥99% agreement rate, Cohen's kappa ranged: 0.78--0.98) between ANZARD and PDCs.
ConclusionThe data linkage resource demonstrates that high linkage rates can be achieved with partially identifiable data and that a population spine, such as the CHeReL's MLK, can be successfully used as a bridge between clinical registries and administrative datasets.

Published: September 2021

Este estudo teve como objetivo compreender a prática de um professor iniciante, tomando como objeto de análise o seu plano de aula. Especificamente buscou-se identificar e analisar no plano de aula a sua trajetória pedagógica de construção, a fundamentação teórica e os desafios desse processo. Optou-se por um relato de experiência de estudo exploratório e autoetnográfico, em que as representações são postas em discussão a partir do exercício de análise crítica de um plano de aula. Esse plano de aula foi dissecado em quatro ações: descrever, informar, confrontar e reconstruir. Como resultado, observou-se a descoberta de uma contradição pedagógica que se define por uma concepção crítica da Educação Física, mas que se revela travestida de traços de tradicionalismo, esportivismo e comportamentalismo emoldurado por um discurso crítico. A partir dessa compreensão, torna-se possível reconstruir a prática e os conteúdos na Educação Física sob outro olhar.

Nowadays, the use of heat pumps (HP) of air split-conditioners in air conditioning and heating systems of small industrial, public and residential facilities is becoming more common. It is known that the nominal heat capacity of HP of air split-conditioners is given in catalogs or reference literature under standard outdoor temperature conditions, namely: outdoor air temperature +7oС, indoor air temperature +21oС. At the same time, manufacturers of air split-conditioners do not ensure that, regardless of the size of heating capacity, all air split-conditioners have the same internal temperature conditions, namely: the evaporation temperature of the refrigerant and its condensation temperature. In this case, the thermodynamic efficiency, which can be best assessed by the exergetic output-input ratio (OIR) of different heating capacity of HP of air split-conditioners, is different; this, in our opinion, is incorrect. However, today there is a lack of mathematical models of bringing the operation of air split-conditioners HP to the similar internal temperature conditions, which will allow us to obtain the same exergetic OIR for different heating capacity of HP. To create the mathematical model of bringing the operation of HP of air split-conditioners to the equal internal temperature conditions, we have proposed them, namely: the evaporation temperature of the refrigerant +0.7oC and its condensation temperature +40oC. Taking these temperatures on the basis of the heat balances of the HP evaporator and HP condenser of air split-conditioners, we obtained the dependences for calculating air flow rates on the evaporator and condenser, which respectively maintain the proposed temperatures.

Authors: An Hee-Su , Kim Deok-Ju
Published: September 2021

Objectives: The aim of this study was to investigate the effect of daily living dual-task training focused on improving attention and executive function of the upper extremities, cognitive function, and quality of life in stroke patients. Methods: We included 30 stroke patients who were hospitalized between July 2020 and October 2020. They were divided into experimental and control groups through randomization. The experimental group performed 20 minutes of dual-task training and received 10 minutes of conventional occupational therapy, while the control group performed 20 minutes of single-task training and received 10 minutes of conventional occupational therapy. Both groups underwent their respective rehabilitation for 30 minutes per session, 5 times per week for 5 weeks. Results: Both groups showed significant improvements in upper extremity function, cognitive function, and quality of life; the experimental group showed higher results for all items. A significant between-group difference was observed in the magnitude of the changes. Conclusion: In stroke patients, dual-task training that combined attention and executive function with daily living activities was found to be meaningful, as it encouraged active participation and motivation. This study is expected to be used as a foundation for future interventions for stroke patients.

A COVID-19 szinte egyik pillanatról a másikra mindenki életét megváltoztatta. Az egész világ felbolydult, hirtelen zárultak le a határok, szűntek meg légi-, és egyéb közlekedési eszközök járatai, alakultak ki karanténos helyzetek, zártak be üzletek, álltak le termelő-, és szolgáltató vállalatok, jutottak a teljes ellehetetlenülés helyzetébe eddig virágzó ágazatok. Becsukódtak a képzési intézmények ajtajai – a bölcsődéktől a felsőoktatásig –, az egészségügyi – és segítő rendszerek leterheltsége az elviselhetetlenség határait súrolta, családok, emberek életét hozta nehéz helyzetekbe, beszűkítve – minden tekintetben – életterüket, létezésük hétköznapi feltételrendszereit. Ez a katasztrófahatás kvázi „gordiuszi csomót” jelent a cégeknek. A megváltozott helyzetben új stratégiák születtek, értékké vált a kreativitás, az intuíció, a sokszor kényszer szülte igényből fakadó diszruptív innováció, a közösség és a család. Jelen munkám egy olyan, a járvány első hónapjaitól megkezdett (2020 decemberével lezárt) kutatás eredményeiről szól, amely során azt vettük górcső alá, hogy szorongatott helyzeteikben a cégek milyen válaszokat adtak a kihívásokra, miképp formálódott a szervezeti magatartásuk, és ki, hogyan és milyen stratégiákkal igyekeztek védekezni, felszínen maradni.

Recovery experiences during vacation and their association with job stressors and health
Authors: Hächler Pascale , Pereira Diana , Achim Elfering
Published: September 2021

Vacations offer opportunities for recovery from work-related stress. However, little is known about the impact of job stressors on recovery experiences during vacation, such as psychological detachment and relaxation. This study investigated detachment and relaxation to mediate the influence of job stressors prior to vacation on recovery during vacation. A total of 136 employees from various occupations completed a questionnaire on their ability to relax and mentally detach from work during a recent vacation. Participants rated perceived time pressure and social exclusion at work prior to their vacation as well as any psychosomatic health complaints or sleep problems during vacation. The results of bootstrap mediation analysis confirmed the mediating role of recovery experiences. The association between job stressors and sleep problems was fully mediated by detachment and relaxation, whereas the association between social exclusion and psychosomatic complaints was fully mediated by relaxation. Furthermore, relaxation partially mediated the association between time pressure and psychosomatic complaints. Not only should the ability of employees to relax and mentally detach be fostered, but job stressors should be reduced in order to allow employees to reach optimal recovery during vacation.

Authors: Castro Barea Josefa , Castro Zamudio Serafina
Published: September 2021

Hay estudios que avalan una relación significativa entre el riesgo de padecer un Trastorno de la Conducta Alimentaria (TCA) y el consumo de tabaco como medida de control del apetito. El objetivo de este estudio es analizar la asociación entre el consumo de tabaco y actitudes y comportamientos presentes en la anorexia y bulimia nerviosas. El diseño del estudio es observacional analítico de casos y controles. La muestra estuvo constituida por 300 participantes de ambos sexos, de entre 12 y 20 años de edad, que respondieron a los siguientes instrumentos de evaluación: EAT-26, EDI-II, BULIT-R y un cuestionario adaptado sobre comportamientos, actitudes y opiniones hacia el tabaco. Se categorizaron las variables cuantitativas continuas y se agruparon a los participantes en grupos sintomáticos y asintomáticos. En el grupo sintomático, se constató que en la variable “haber fumado diariamente, al menos un cigarrillo, durante seis o más meses en la vida” se obtuvo una diferencia estadísti-camente significativa χ² (1, N = 300) = 7.536, p< .01, y de magnitud baja (V = .159), en el EAT-26. Para el BULIT-R en esta misma variable se alcanzó una diferencia estadís-ticamente significativa χ²(1, N = 300) = 8.740, p< .01, y de magnitud baja (V= .171). Para la variable “consumo diario actual de cigarrillos” se alcanzó una diferencia estadística-mente significativa χ² (2, N = 300) = 15.561, p< .01, y de magnitud baja (V = .228), en el EAT-26. Para el BULIT-R en esta misma variable se obtuvo una diferencia estadís-ticamente significativa χ² (2, N = 300) = 6.237, p< .05, y de magnitud baja (V = .144). Los resultados constatan la relación existente entre el consumo de tabaco y grupos sin-tomáticos afines a los TCA.
Satisfacción vital y su relación con otras variables psicosociales en población española residente en Alemania
Authors: Vallejo-Martín Macarena , Moreno Jiménez María del Pilar
Published: September 2021

Este estudio analiza qué variables psicosociales están relacionadas con la satisfacción vital en población española residente en Alemania. Para ello se consideran las siguientes: apoyo social, autoestima, satisfacción laboral y apego e identidad con el lugar. Se tienen en cuenta también factores sociodemográficos, en concreto: empleo, conocimiento del alemán, ingresos mensuales recibidos y clase social percibida. Con una muestra de 206 personas, los resultados muestran un nivel medio o medio-alto en las variables psicosociales consideradas y correlaciones significativas entre ellas. Respecto a los factores sociodemográficos, no se muestran diferencias significativas en satisfacción vital por el hecho de tener empleo, pero sí para el resto de factores en sentido ascendente. Entre ellos, aquel de mayor efecto es la clase social percibida. Los resultados también indican que satisfacción laboral intrínseca, clase social percibida, apego al lugar y autoestima son variables predictivas de satisfacción vital, explicando un 55.5% de la varianza. Según lo anterior, se observan diferencias con otros estudios sobre satisfacción vital en población inmigrante.
¿Estrellas o constelaciones? Implicaciones de los estudios cognitivos para el modelo dimensional de la emoción
Authors: Olivera-La Rosa Antonio , Arango Tobón Olber Eduardo , Martí Noguera Juan José
Published: September 2021

Uno de los principales debates dentro del estudio de la psicología de la emoción concierne a la concepción de las emociones como constructos psicológicos unificados (categoriales/discretos) en contraposición con el enfoque di-mensional del episodio emocional. En este marco, el modelo dimensional de Russell (2003) destaca en el panorama académico al constituir una propuesta integradora que da cuenta de una serie de problemas históricos del ámbito de estudio. Con este fin, se realiza una aproximación analítica a dicho modelo y se argumenta su viabilidad. El presente artículo tiene como objetivo revisar la evidencia empírica a favor de cuatro hipótesis que sostiene el modelo dimensional de Russell: (1) Existe una primacía temporal de los afectos básicos frente a los componentes más cognitivos en el desarrollo de la emoción, (2) los cambios afectivos percibidos facilitan la accesibilidad del material hedónicamente congruente, (3) la mente humana puede atribuir erróneamente la experimentación de un determinado core affect al estímulo incorrecto, y (4) la experimentación de los componentes dimensionales facilita la ocurrencia de respuestas cognitivas congruentes. Se concluye que la combinación de componentes dimensionales inespecíficos, tanto de tipo puramente afectivo como de carácter más “cognitivo” constituyen ocasionalmente los prototipos emocionales. En consecuencia, se propone que el modelo dimensional de Russell (2003) constituye una alternativa integradora de gran potencial para abordar el estudio de la naturaleza de la emoción.

Se presentan los antecedentes de la técnica y se discuten algunas cuestiones metodológicas que es necesario considerar para diseñar una investigación empleando el modelo de CPL, como los diferentes tipos de aparatos disponibles, las diferentes fases del protocolo y sus posibles variaciones, el tipo de diseño (sesgado vs. no sesgado) o la necesidad de considerar los efectos del tiempo. Posteriormente se discuten algunas cuestiones a tener en cuenta a la hora de interpretar los datos obtenidos, como qué es lo que aprende el animal, la presentación de la variable dependiente, la influencia de la novedad, el aprendizaje dependiente de estado, la inhibición latente, los efectos motores y cognitivos de las drogas o la comparación con los datos provenientes del modelo de la autoadministración de drogas. Se exponen las principales aplicaciones, ventajas y limitaciones de la técnica y se finaliza con algunas propuestas para superar las principales críticas que ha recibido este modelo.
Fortalezas psicológicas y diferencias de sexo en adolescentes
Authors: Reyes Martín Sara , Ferragut Marta
Published: September 2021

El presente estudio examina las fortalezas psicológicas propuestas por el Modelo VIA (Values In Action) en adolescentes, y sus relaciones con la felicidad y la salud mental, considerando las diferencias de sexo. La muestra estuvo constituida por 117 estudiantes de bachillerato (μ =16.90, σ =.81) de Málaga, quienes completaron el Cuestionario de Fortalezas Humanas (VIA-120), el Cuestionario de Salud General (GHQ-12) y el Ítem único de Felicidad. Los resultados muestran un predominio de las fortalezas incluidas en el valor de humanidad, en detrimento de las de templanza y la fortaleza espiritualidad. Se hallaron correlaciones moderadas entre todas las fortalezas del valor trascendencia con la felicidad y la salud mental, encontrándose la correlación más fuerte entre dichas variables con la fortaleza optimismo. Por otro lado, se han observado en los varones medias superiores a las mujeres en vitalidad, prudencia, autorregulación y optimismo. El estudio corrobora que las fortalezas son recursos psicológicos que favorecen otras características positivas, siendo el sexo una variable que influye en los resultados.
¿Psicología positiva para afrontar la radicalización y el terrorismo? Un análisis del discurso de Obama en el Cairo
Authors: Moyano Manuel , Bermúdez Manuel I. , Ramírez Antonia
Published: September 2021

Desde los atentados terroristas del 11S, el afrontamiento de la radicalización y el terrorismo yihadista por parte de las sociedades occidentales ha estado en primera línea de la agenda política interior y exterior. Durante este tiempo, se ha evidenciado la influencia que pueden desempeñar los dirigentes políticos en su interacción con las instituciones, la ciudadanía y las organizaciones terroristas. En la presente investigación se realiza un estudio de caso del discurso pronunciado por Barack Obama el 4 de junio de 2009 en la Universidad de El Cairo (“A New Beginning”). Para ello se examina su contenido y estructura interna utilizando como referente teórico-conceptual la clasificación de virtudes y fortalezas delimitada por Peterson y Seligman (2004) en el marco de la Psicología Positiva. Este discurso supuso un punto de inflexión en las relaciones entre Estados Unidos y el mundo árabo-musulmán, pudiendo considerarse un genuino ejercicio de comunicación positiva cuyas implicaciones están aún por determinar, dado que sigue ejerciendo influencia en la política interior y exterior de la administración Obama. Se concluye que, en un mundo globalizado y en red donde los riesgos y adversidades requieren abordajes innovadores, es necesaria más que nunca una comunicación social capaz de promover virtudes y fortalezas asociadas al optimismo, la esperanza, la confianza, la resistencia o la vitalidad

OBJECTIVE

To compare mineral types of naturally occurring uroliths in ferrets (Mustela putorius furo) from North America, Europe, and Asia and to identify potential risk factors associated with cystine urolithiasis in ferrets.

SAMPLES

1,054 laboratory submission records of uroliths obtained from ferrets between January 1, 2010, and December 31, 2018.

PROCEDURES

For this cross-sectional study, the medical records databases at 4 diagnostic laboratories were searched for records of submissions of uroliths obtained from ferrets. Data collection included submission date; ferret sex, neuter status, and age; receiving laboratory and continent; and urolith mineral type. Regression analyses were performed to identify variables associated with cystine uroliths.

RESULTS

Of the 1,054 urolith submissions, 1,013 were from North America, with 92.6% (938/1,013; 95% CI, 90.8% to 94.1%) cystine uroliths, and 41 were from Europe and Asia, with only 26.8% (11/41; 95% CI, 15.7% to 41.9%) cystine uroliths. Median age was 2.0 years for ferrets with cystine urolithiasis versus 4.0 years for those with other types of uroliths. Submissions were more likely cystine uroliths for ferrets in North America versus Europe and Asia (adjusted OR [aOR], 59.5; 95% CI, 21.4 to 165.6), for ferrets that were younger (aOR, 0.67; 95% CI, 0.58 to 0.77), or for submissions in 2018 versus 2010 (aOR, 21.1; 95% CI, 5.1 to 87.9).

CONCLUSIONS AND CLINICAL RELEVANCE

Results indicated that the proportion of submissions that were cystine uroliths dramatically increased in North America between 2010 and 2018. There is an urgent need to determine underlying causes and mitigate cystine urolithiasis in ferrets.

Published: September 2021

OBJECTIVE

To evaluate the efficacy of ethylene oxide (EtOH) sterilization of 4 different waterproof camera cases and the ability of those sterilized cases to maintain a sterile barrier for intraoperative camera use.

SAMPLE

3 action cameras, 1 smartphone, and associated waterproof cases.

PROCEDURES

Cases were inoculated by immersion in medium containing Staphylococcus pseudintermedius, Escherichia coli, and Pseudomonas aeruginosa and then manually cleaned and subjected to EtOH sterilization. Cameras were disinfected, loaded into sterile cases, and sterilely operated for 2 hours. Samples were collected from cases after inoculation, EtOH sterilization, camera loading, and 1 and 2 hours of operation and from all cameras after 2 hours of operation. Procedures were repeated twice, followed by an additional challenge round wherein cameras were purposefully contaminated prior to loading. All samples underwent bacterial culture.

RESULTS

All cases were successfully sterilized, and loading of nonsterile cameras into sterile cases caused no contamination when cameras had been disinfected beforehand. Nonpathogenic environmental contaminants were recovered from 6 of 64 culture samples and 2 of 4 room samples. During the challenge round, only the postload sample for 1 case yielded E coli, suggesting sterile glove contamination; however, postload, 1-hour, and 2-hour samples for the GoPro case yielded E coli and S pseudintermedius, suggesting major contamination.

CONCLUSIONS AND CLINICAL RELEVANCE

Results suggested that the evaluated cases can be safely sterilized with EtOH and used for image acquisition by aseptically prepared surgeons when cameras are disinfected prior to loading. Except for the GoPro camera, camera use did not jeopardize sterile integrity.

Published: September 2021

The article reports on the results of the numerical and the laboratory tests to determine the effect of concrete damages near support areas in compressed zone of the reinforced concrete beams on their residual bearing capacity of inclined sections. According to the experimental plan, 15 single-span freely supported experimental samples with dimensions of 100×200×1200 mm made with different artificial damages within the shear span aν (1d, 2d, and 3d) were tested. The numerical test of prototypes was performed in software complex LIRA-SAPR 2017. The results of laboratory and numerical experiments showed good convergence regarding the bearing capacity, however, the nature of the fracture in samples B11-B14 did not match. Empirical - conducting laboratory experiments on samples using modern methods of measurement; numerical modelling – using software complex LIRA-SAPR 2017; analysis and statistical processing of the obtained research results; comparison of the obtained results; abstraction; generalization; deduction; formulation of the main conclusions and recommendations. The analysis found that the bearing capacity decreases with increased area of damage and shear span. Conducting the calculations in software complex LIRA-SAPR allows to predict the work elements and determine the bearing capacity with good accuracy, but in comparison with the real data there still are some differences in the character of destruction.
Rethinking niche tourism: The example of backpacking
Authors: Richards Greg
Published: September 2021

This conceptual paper re-evaluates the concept of niches in tourism markets. As many regions are now attempting to address niche markets in tourism as a development strategy, understanding of the dynamics of niche markets is crucial. Current approaches are often limited to seeing niche markets as simple subsectors of larger consumer markets. We argue for a broader view of market niches as forms of social rituals involving both consumers and producers with a mutual focus of attention. Based on the work of Randall Collins we examine how interaction rituals are produced and maintained, and how these are also reflected in niche markets, such as backpacking. We illustrate the how backpacking produces a mutual focus of attention and boundaries to outsiders, helping to sustain the niche over the longer term. This analysis has implications for producers hoping to tap into niche markets, as they too need to become part of the niche community.

Published: September 2021

Modified concretes and fiber concretes for rigid pavements have been investigated. Four-factor experiment was conducted. The amount of Portland cement, polypropylene fiber, metakaolin and polycarboxylate superplasticizer varied in the experiment. All mixtures had the same mobility S2.

The active mineral additive metakaolin increases the compressive strength of concrete and its tensile strength in bending. The amount of metakaolin at the level of 15.20 kg/m3 is rational. Due to a decrease in W/C with an increase in the amount of superplasticizer Coral ExpertSuid-5 to 0.9.1%, the compressive strength of concrete increases by 5.7 MPa, the tensile strength in bending increases by 0.5.0.6 MPa. Due to the introduction of polypropylene fiber, the tensile strength of concrete in bending increases by 0.6.0.9 MPa, the frost resistance of concrete increases by 50 cycles. Due to the use of a rational amount of superplasticizer and metakaolin, the frost resistance of concretes and fiber concretes concrete increases by 50-100 cycles. The use of a rational amount of modifiers and fiber reduces the abrasion of concretes by 40.45%.

The developed modified fiber concretes of rigid pavements, depending on the amount of Portland cement, have compressive strength from 55 MPa to 70 MPa, tensile strength in bending from 8 MPa to 9.5 MPa, frost resistance from F350 to F450, abrasion from 0.30 to 0.40 g/cm2. Such strength, frost resistance and abrasion resistance allow the use of fiber concretes in pavements with the greatest load and ensures high durability of the material and corresponds to the directions and tasks of the state scientific and technical program “National Transport Strategy of Ukraine for the period up to 2030”
