Abstract
The aim of this study is to show the influence of using compliant interlayers as crack arresters for three-dimensional (3-D)-printed polymeric structures. To investigate the effectiveness of compliant interlayers, specimens consisting of a stiff and brittle matrix and thin compliant interlayers were printed. The results of these polymeric composites were compared to pure matrix material samples. To generate specimens, a commercially available material extrusion-based desktop 3-D-printer was used. Additively manufactured samples were tested in both impact as well as fracture mechanical tests. The application of a compliant interlayer as crack arrester showed high potential in both types of test. Instrumented Charpy impact tests according to EN ISO 179-2 revealed an increase of notched impact strength from 5.0 ± 0.1 kJm−2 to 25 kJm−2 (energy up to Fmax) and 136 ± 2.6 kJm−2 (total energy during testing), respectively. This indicates an increase of roughly 725% and 2,720%, while the maximum force during testing remained almost unchanged at approximately 200 N. Interestingly, the exact position as well as the number of compliant interlayers did not show a significant influence on the results. Therefore, tests that are more detailed were conducted on specimens including only a single interlayer. Further tests consisted of J-integral testing on specimens with aforementioned single compliant interlayers. Crack resistance (J-R curves) were generated using the multi-specimen approach and evaluation according to the protocol of the European Structural Integrity Society. Although a special data-shifting procedure has to be applied to interpret results more clearly, J-integral values showed a significant increase of 250 % at the interface between materials compared to the pure matrix material.
Ubiquitin and Ubiquitin-Like Proteins in the Critical Equilibrium between Synapse Physiology and Intellectual Disability
Authors: Folci Alessandra , Mirabella Filippo , Fossati Matteo 
Published: July 2020

AbstractPosttranslational modifications (PTMs) represent a dynamic regulatory system that precisely modulates the functional organization of synapses. PTMs consist in target modifications by small chemical moieties or conjugation of lipids, sugars or polypeptides. Among them, ubiquitin and a large family of ubiquitin-like proteins (UBLs) share several features such as the structure of the small protein modifiers, the enzymatic cascades mediating the conjugation process, and the targeted aminoacidic residue. In the brain, ubiquitination and two UBLs, namely sumoylation and the recently discovered neddylation orchestrate fundamental processes including synapse formation, maturation and plasticity, and their alteration is thought to contribute to the development of neurological disorders. Remarkably, emerging evidence suggests that these pathways tightly interplay to modulate the function of several proteins that possess pivotal roles for brain homeostasis as well as failure of this crosstalk seems to be implicated in the development of brain pathologies. In this review, we outline the role of ubiquitination, sumoylation, neddylation, and their functional interplay in synapse physiology and discuss their implication in the molecular pathogenesis of intellectual disability (ID), a neurodevelopmental disorder that is frequently comorbid with a wide spectrum of brain pathologies. Finally, we propose a few outlooks that might contribute to better understand the complexity of these regulatory systems in regard to neuronal circuit pathophysiology.

Students use social media for social activities more than learning but studies on the proficiency for learning has been less researched. This study therefore assessed the undergraduate students’ proficiency’ level of utilizing social media for learning in Nigeria. The study employed the quantitative research method. Four hundred and fifty (450) respondents were randomly sampled across universities in Nigeria on which a structured questionnaire was administered on the students. The research questions were answered using mean, while t-test statistic was used to test the two hypotheses. Results of the research revealed that the proficiency level of undergraduates on the utilization of social media for learning was high and there was no significant difference between male and female undergraduates' utilization and undergraduates' proficiency towards the utilization of social media for learning. The study concluded that undergraduate students have good proficiency level on the utilization of social media for learning.

Multifuncionalidad de la vida campesina en contextos de conflictos ambientales y construcción de paz en la Amazonía colombiana.
Authors: Arias Sara Camila 
Published: July 2020

Las dinámicas extractivas en la Amazonía colombiana fueron frenadas parcialmente por la dinámica de guerra presente en el país, con el cese al fuego, aunado a la insuficiente presencia estatal y las persistentes condiciones de desigualdad social y también la continuidad de otros actores armados, esta área es escenario de economías extractivas e ilegales, al tiempo que permanece siendo fuente de supervivencia para las comunidades campesinas que han habitado esas tierras durante décadas y se han aproximado a una forma de relacionamiento equilibrada con el ecosistema.
Ante este contexto de conflictividad el Estado ha decidido criminalizar cualquier tipo de intervención, incluyendo la de las comunidades locales históricamente asentadas allí, y también ampliar las áreas protegidas, lo cual se ha acompañado de la militarización de su protección, que se conecta con la judicialización a quienes sean considerados actores de deforestación. A pesar de esta nueva dinámica de conflicto, ya no armado, sino social y ambiental, las comunidades campesinas y las personas en proceso de reincorporación le apuestan a la construcción de paz, defendiendo su territorialidad, impulsando diferentes proyectos productivos que hacen sinergia en el contexto de la multifuncionalidad de la vida campesina de la que ahora forman parte.
La incorporación de la Hacienda “El Murciélago” en el territorio del Parque Nacional Santa Rosa: un proyecto geopolítico (1978-1986)
Authors: Madriz-Sojo Gabriel , Díaz Bolaños Ronald 
Published: July 2020

El presente trabajo visibiliza el territorio del Sector Murciélago del Parque Nacional Santa Rosa no solamente como una zona protegida, con remanentes de bosque tropical seco y especialmente relevante por su resguardo de los ecosistemas del Pacífico Seco costarricense; sino también como un espacio de poder, que condicionado por su situación limítrofe con Nicaragua y el contexto geopolítico centroamericano e internacional, vio reconfiguradas sus prácticas humanas desarrolladas durante el período de estudio. Esto debido a cambiantes disposiciones de las élites políticas nacionales: desde una inicial tendencia conservacionista con la expropiación hacendaria durante la administración Carazo Odio (1978-1982), a una intensificación militar y transgresión ambiental durante la administración Monge Álvarez (1982-1986), continuada pero gradualmente dirimida durante el primer año de la administración Arias Sánchez (1986-1990). A través de un análisis documental de fuentes de archivo, hemerográficas, secundarias y mapas el artículo desarrolla un recorrido histórico de los principales procesos de aprovechamiento, uso y redistribución territorial del espacio señalado, contribuyendo a la desmitificación de discursos oficiales respeto a los proyectos de conservación del Estado costarricense. Finalmente, ésta concluye que la estricta aplicación de las políticas de conservación dentro de la zona estudiada se vio constreñida por una variable agenda política de seguridad nacional, una canalización de demandas de grupos sociales, inconstantes flujos presupuestarios debido a la crisis económica de inicios de la década de 1980 y una denotada desidia institucional en la gestión del parque.

Háttér és célkitűzésa vizsgálat a lassú, ún. K-életstratégia és a nehézségekkel szembeni ellenálló képesség, valamint a szorongásérzékenység lehetséges összefüggéseit tárja fel. Evolúciós, pozitív és klinikai pszichológiai területeket ötvöző vizsgálatunk megközelítésmódja újdonságnak számít. Célunk a reziliencia és a K-stratégia közötti összefüggések vizsgálata.Módszera papír-ceruza alapú tesztekkel végzett vizsgálatban hozzáférhetőségi egyetemista mintavételezés során 674 személy vett részt, önkéntes alapon. A résztvevők által kitöltött kérdőívcsomag a Connor–Davidson Reziliencia Kérdőívet, az Életstratégia Kérdőívet és a Szorongásérzékenység Indexet tartalmazták.EredményekA korrelációs és lineáris regressziós statisztikai elemzések igazolták, hogy pozitív kapcsolat figyelhető meg a lassú életstratégia és a reziliencia között. A szorongásérzékenység ugyanakkor negatív összefüggést mutat az említett változókkal. A nemi különbségek szintén megmutatkoznak, bár a minta jellemzői miatt ezek további vizsgálata szükséges.KövetkeztetésekAz eredményeink alapján elmondható, hogy a fiatal felnőttek esetén gyenge, ám szignifikáns kapcsolat áll fenn a K-életstratégia és a reziliencia között. Az életstratégiához tartozóan a reziliens személyek intim és tartós partnerkapcsolatokra törekednek, emellett kognitív szinten jellemzőjük az előrelátás, a tudatos és következetes tervezési képességek kibontakoztatása. A szorongásérzékenység bár helyenként statisztikailag szignifikáns kapcsolatot mutat a fenti változókkal, ezek mértéke sok esetben igen alacsony. A nemi különbségek releváns szempontként jelenhetnek meg, ám ezek tisztázásához a minta további bővítése szükséges.

Published: July 2020

Háttér és célkitűzésekA nevetségessé válástól való félelem (gelotofóbia) eddig kevéssé kutatott jelenség volt a pszichológiában. Kutatásunkban a nevetségessé válástól való félelmet az önbecsülésen és a negatív megítéléstől való félelmen keresztül vizsgáltuk meg. Azt feltételeztük, hogy az alacsony önbecsülés a negatív megítélésen keresztül együtt jár a nevetségessé válástól való félelemmel.MódszerAz online kérdőíves kutatásban 666 fő vett részt (239 férfi, 427 nő). A résztvevők egy 3 kérdőívből álló tesztcsomagot kaptak, mely tartalmazta a gelotofóbiát mérő Geloph-15 kérdőívet (Boda-Ujlaky, Proyer és Ruch, 2012), a Rosenberg Önértékelés Skálát (Sallay, Martos, Földvári, Szabó és Ittzés, 2014) és a Félelem a Negatív Megítéléstől Skálát (Perczel-Forintos és Kresznerits, 2017).EredményekAz önbecsülés szignifikáns közvetett kapcsolatban van a nevetségessé válástól való félelemmel. A negatív megítéléstől való félelemnek mediáló szerepe van a gelotofóbia és az önbecsülés között. A demográfiai változókat tekintve a nőkre jellemzőbb a nevetségessé válástól való félelem, mint a férfiakra.KövetkeztetésAz önbecsülésnek a negatív megítéléstől való félelem aspektusa az, ami gelotofóbiához vezethet.

Objetivo: Descrever características da alimentação dos participantes da coorte NutriNet Brasil imediatamente antes e na vigência da pandemia de COVID-19.
Métodos: Os dados deste estudo provêm de coorte de adultos criada para investigar prospectivamente a relação entre alimentação e morbimortalidade por doenças crônicas não-transmissíveis no Brasil. Para este estudo, foram selecionados os primeiros participantes (n=10.116) que responderam por duas vezes questionário simplificado sobre sua alimentação no dia anterior, a primeira ao ingressar no estudo, entre 26 de janeiro e 15 de fevereiro de 2020, e a segunda entre 10 e 19 de maio de 2020. O questionário indaga sobre o consumo de marcadores de alimentação saudável (hortaliças, frutas e leguminosas) e não saudável (alimentos ultraprocessados). Comparações de indicadores baseados no consumo desses marcadores antes e na vigência da pandemia são apresentadas para o conjunto da população estudada e segundo sexo, faixa etária, macrorregião de residência e escolaridade. Testes qui-quadrado e testes t foram utilizados para comparar proporções e médias, respectivamente, adotando-se p <0,05 para identificar diferenças significantes.
Resultados: Para o conjunto dos participantes, identificou-se aumento modesto, porém estatisticamente significante, no consumo de marcadores de alimentação saudável e estabilidade no consumo de marcadores de alimentação não saudável. Esse padrão favorável de mudanças na alimentação com a pandemia se repetiu na maior parte dos estratos sociodemográficos. Padrão menos favorável de mudanças, com tendência de aumento no consumo de marcadores de alimentação saudável e não saudável foi observado nas macrorregiões Nordeste e Norte e entre pessoas com menor escolaridade, sugerindo desigualdades sociais na resposta à pandemia.
Conclusões: Caso confirmada, a tendência de aumento no consumo de alimentos ultraprocessados nas regiões economicamente menos desenvolvidas e nas pessoas com menor escolaridade preocupa, pois o consumo desses alimentos aumenta o risco de obesidade, hipertensão e diabetes, cuja presença aumenta a gravidade e a letalidade da COVID-19.

Authors: Dobrokhotova Ju. E. , Kalimatova D. M. , Ilyina I. Yu. 
Published: July 2020

Aim: to assess the effectiveness of using dienogest in combination with postoperative interventions in patients with endometriosis.Materials and methods. There were enrolled 102 patients with signs of external endometriosis underwent examination and surgical treatment, subdivided into 2 groups: 67 – main group (after surgical treatment, received dienogest 2 mg/day for 6 months), 35 – comparison group received no hormone therapy in the postoperative period. Surgical treatment included removal of endometrioid ovarian cysts, endometriosis foci on the pelvic peritoneum and sacral uterine ligaments. Course of the early postoperative period (up to 1 month after the intervention) as well as the long-term dynamics of the disease manifestations (3, 6, 12 and 15 months later) were assessed.Results. Dienogest was administered after surgical treatment due to endometriosis that reduced the severity of dyspareunia and intensity of chronic pelvic pain by 3.5- and 2-fold, respectively. The probability of achieving control over uterine bleeding 6 month after the onset of treatment due to endometriosis manifested with metrorrhagia showed that combination treatment (consisting of dienogest) was 3.19-fold higher compared to surgical treatment alone (OR = 3.19; 95 % CI = 1.70–11,0; p < 0,05). Recovery of normal menstrual cycle in 63 (94.0%) women of the main group was established 1.5–2 months after completing of hormonal treatment, while in the comparison group pain and dysmenorrhea relapsed in some patients at the 6-month follow-up. Decreased libido as a side effect in patients who treated with dienogest was observed in 2 (3.0 %) women.Conclusion. Dienogest was highly effective in the combination treatment of patients with verified endometriosis that resulted in reduced severity of pain and metrorrhagia. The drug was featured by low level of side effects. Thus, a combination treatment of endometriosis containing dienogest at a dose of 2 mg/day applied during postoperative period allows to reduce the severity of the disease clinical manifestations and improve treatment outcome.
Has True Romance Disappeared in Consumer Society? A Morinian and Baudrillardian Reflection of the Acute Crisis of Simulation
Authors: Moser Keith 
Published: July 2020

ABSTRACTIn the context of the transdisciplinary philosophy of Edgar Morin and Jean Baudrillard, this essay delves into the gap between image and reality that has further problematized the elusive quest for love and companionship living in a technologized world. Both thinkers persuasively maintain that it is becoming increasingly difficult for the postmodern subject to establish any kind of meaningful affective bond with another person due to the proliferation of idealistic images of romance that bombard us from all sides in the digital age. According to Morin and Baudrillard, celebrities play an important hegemonic role in the transmission of pervasive hyperreal fiction denoting utopian signs of love that stand in for true romance in the collective imagination of the consumer citizen. In a post‐Marxist landscape in which the incessant reproduction of commercial simulacra is paramount for the survival of the capitalist paradigm, these unconventional philosophers and sociologists explain that simulated reality is the most oppressive and effective form of social control ever conceived.
