Estimation of the Scale of Food Waste in Hotel Food Services—A Case Study
Authors: Tomaszewska Marzena , Bilska Beata , Tul-Krzyszczuk Agnieszka , Kołożyn-Krajewska Danuta
Published: January 2021

The problem of food waste in food services, which is global and essentially affects the entire world, is a major challenge for the hospitality industry. At the same time, it should be noted that this problem has not been sufficiently studied, which makes it difficult to reduce it effectively. The study was carried out in four hotels in late 2019 and early 2020. In order to determine the scale of food waste, the diary method was used, which consists of systematically recording, for seven days, in forms prepared for workstations, the weight of all food products and unused food, including the stage of the technological process. In the hotels under study, most food was wasted in the serving department, i.e., in the buffet in the dining room or in the form of plate waste (on average 72.55% of wasted food). After taking into account the number of hotel guests served, it was found that in the investigated facilities, an average of 0.046 kg was wasted from each serving offered to guests in the form of plate waste, which constituted 5.8% of its weight. In sum, it should be stated that in order to reduce food waste, it is necessary to educate both food services staff and consumers. Employees should be trained in the proper handling of food. Consumer education, on the other hand, should be directed toward raising awareness of the negative impact of food waste, such as that on the natural environment. In addition, it should indicate what action everyone can take to limit this negative phenomenon, whether at home, in the workplace, or in a food service establishment.
Neutrino Oscillations in Neutrino-Dominated Accretion Around Rotating Black Holes
Authors: Uribe Juan David , Becerra-Vergara Eduar Antonio , Rueda Jorge Armando
Published: January 2021

In the binary-driven hypernova model of long gamma-ray bursts, a carbon–oxygen star explodes as a supernova in the presence of a neutron star binary companion in close orbit. Hypercritical (i.e., highly super-Eddington) accretion of the ejecta matter onto the neutron star sets in, making it reach the critical mass with consequent formation of a Kerr black hole. We have recently shown that, during the accretion process onto the neutron star, fast neutrino flavor oscillations occur. Numerical simulations of the above system show that a part of the ejecta stays bound to the newborn Kerr black hole, leading to a new process of hypercritical accretion. We address herein, also for this phase of the binary-driven hypernova, the occurrence of neutrino flavor oscillations given the extreme conditions of high density (up to 1012 g cm−3) and temperatures (up to tens of MeV) inside this disk. We estimate the behavior of the electronic and non-electronic neutrino content within the two-flavor formalism (νeνx) under the action of neutrino collective effects by neutrino self-interactions. We find that in the case of inverted mass hierarchy, neutrino oscillations inside the disk have frequencies between ∼(105–109) s−1, leading the disk to achieve flavor equipartition. This implies that the energy deposition rate by neutrino annihilation (ν+ν¯→e−+e+) in the vicinity of the Kerr black hole is smaller than previous estimates in the literature not accounting for flavor oscillations inside the disk. The exact value of the reduction factor depends on the νe and νx optical depths but it can be as high as ∼5. The results of this work are a first step toward the analysis of neutrino oscillations in a novel astrophysical context, and as such, deserve further attention.

Published: January 2021

Because the incidence of Merkel cell carcinoma (MCC) has increased significantly during the last 10 years and it is recognized that Merkel cell polyomavirus (MCPyV) and ultraviolet (UV) radiation represent two different etiological inputs sharing clinical, histopathological, and prognostic similar features, although with different prognosis, this study investigated the detection of MCPyV in skin and lymph nodes with histological diagnosis of MCC. Formalin-fixed paraffin-embedded tissue (FFPE) were retrieved from archived specimens and MCPyV non-coding control region (NCCR) and viral capsid protein 1 (VP1) sequences were amplified and sequenced. Results provide an interesting observation concerning the discrepancy between the MCPyV DNA status in primary and metastatic sites: in fact, in all cases in which primary and metastatic lesions were investigated, MCPyV DNA was detected only in the primary lesions. Our data further support the “hit-and-run” theory, also proposed by other authors, and may lead to speculation that in some MCCs the virus is only necessary for the process of tumor initiation and that further mutations may render the tumor independent from the virus. Few point mutations were detected in the NCCR and only silent mutations were observed in the VP1 sequence compared to the MCPyV MCC350 isolate. To unequivocally establish a role of MCPyV in malignancies, additional well-controlled investigations are required, and larger cohorts should be examined.
Investigating the Effects of Agricultural Water Management in a Mediterranean Coastal Aquifer under Current and Projected Climate Conditions
Authors: Pisinaras Vassilios , Paraskevas Charalampos , Panagopoulos Andreas
Published: January 2021

Coastal delta plains are areas with high agricultural potential for the Mediterranean region because of their high soil fertility, but they also constitute fragile systems in terms of water resources management because of the interaction of underlying aquifers with the sea. Such a case is the Pinios River delta plain located in central Greece, which also constitutes a significant ecosystem. Soil and Water Assessment Tool (SWAT) and SEAWAT models were combined in order to simulate the impact of current water resources management practices in main groundwater budget components and groundwater salinization of the shallow aquifer developed in the area. Moreover, potential climate change impact was investigated using climate data from Regional Climate Model for two projected periods (2021–2050 and 2071–2100) and two sea level rise scenarios (increase by 0.5 and 1 m). Modeling results are providing significant insight: although the contribution of the river to groundwater inflows is significant, direct groundwater recharge from precipitation was found to be higher, while capillary rise constitutes a major part of groundwater outflows from the aquifer. Moreover, during the simulation period, groundwater flow from the aquifer to the sea were found to be higher than the inflows of seawater to the aquifer. Regarding climate change impact assessment, the results indicate that the variability in groundwater recharge posed by the high variability of precipitation during the projected periods is increasing the aquifer’s deterioration potential of both its quantity and quality status, the latter expressed by the increased groundwater Cl− concentration. This evidence becomes more significant because of the limited groundwater storage capacity of the aquifer. Concerning sea level rise, it was found to be less significant in terms of groundwater salinization impact compared to the decrease in groundwater recharge and increase in crop water needs.

No era paz, era silencio. El sonido en el paisaje sociosemiótico urbano del “Estallido social” chileno desde los ECDM
Authors: Domingo Daniel
Published: January 2021

Este artículo tiene por objetivo realizar un análisis crítico del discurso multimodal de 11 textos que conforman el paisaje sociosemiótico de Santiago y que hacen referencia al sonido en el contexto del estallido social chileno. Para ello, utilizamos un modelo dinámico de tres niveles de análisis que abarca el texto multimodal sonoro, el paisaje sociosemiótico urbano y el contexto sociopolítico y cultural del “estallido social”, abordado desde los Estudios Críticos del Discurso Multimodal (ECDM). Los resultados indican que el sonido -grito, voz y ruido, es inscrito con una intencionalidad de amenaza y de resistencia en contra del gobierno, de sus instituciones y del modelo neoliberal. El silencio, al contrario, alude a la complicidad con las políticas estatales o es producido debido al miedo a enfrentarse a la represión. Además, el sonido representado visibiliza las demandas específicas de movimientos como el feminismo y los procesos de resistencia cultural y revitalización político-identitaria del pueblo mapuche.
A UTILIZAÇÃO DE REPRESENTAÇÕES CARTOGRÁFICAS EM MATERIAIS DIDÁTICOS DE GEOGRAFIA NO ENSINO FUNDAMENTAL: UMA ANÁLISE DESCRITIVA
Authors: Zucherato Bruno , Henrique Albuquerque Bruna
Published: January 2021

Desde o seu surgimento, a ciência geográfica possui uma grande relação com o ensino escolar, sendo este o maior contato da população em geral com esse domínio do conhecimento. Assim percebe-se que a Geografia Escolar tem uma posição estratégica no meio como a Geografia é percebida e reproduzida em nossa sociedade, isso inclui também a utilização das representações cartográficas e a veiculação desses conteúdos por meio dos materiais didáticos que fazem parte do cotidiano escolar. Com base nessa questão o presente artigo resultado de uma pesquisa realizada durante o primeiro semestre de 2020 como parte das atividades do laboratório de ensino da UFMT Campus Aaraguaia, busca realizar um levantamento quantitativo e uma análise qualitativa de como os mapas são abordados por diferentes livros didáticos de Geografia direcionados a alunos do 6º ano do Ensino Fundamental. Para tanto, foram verificados a proporção entre mapas e páginas dos materiais escolhidos, bem como o contexto de ensino com os quais os mapas foram abordados, o tamanho das representações incluídas, a sua escala e as suas relações com os conteúdos abordados. Para esse levantamento foram escolhidas 3 coleções de Geografia aprovadas pelo PNLD e os resultados mostram que as 3 coleções apresentaram diferenças significativas na maior parte dos parâmetros analisados com base principalmente nas diferenças dos padrões editoriais estabelecidos em cada uma das propostas incluídas e ainda que esses parâmetros em geral não são levados em consideração na escolha dos materiais didáticos feitos pelas escolas e pelos professores nas escolas públicas brasileiras. Ressalta-se ainda que a comunicação cartográfica apresenta grande importância e espaço no ensino de Geografia, reivindicando assim uma maior importância dentro das publicações de materiais didáticos correntes.

Published: January 2021

Polydimethylsiloxane (PDMS)-based mold prepared using a 3D-printed structure is a cost-effective material and tool to fabricate robust microfluidic chips (MCs) without requiring expensive clean room facilities. A capillary-based MC made of PDMS can be attached onto a glass substrate to visualize the chemical reactions in different types of pH buffer solutions (BSs) flowing through microflow channels (MFCs) using terahertz (THz) image sensing technology. In this study, we designed a microfluidic structure with two inlet wells and an outlet well, equipped with a Si:sapphire substrate to visualize the chemical interaction between BSs injected at different pH values (4 and 10) through an MFC. THz imaging maps were captured during the flow of the BSs using a THz chemical microscope, and the fluid dynamics was studied. We determined and plotted the variation in the THz amplitude data with respect to the BS concentration and analyzed the characteristics of the data.

Published: January 2021

We applied hydrogen plasma treatment (HPT) on a titanium oxide/silicon oxide/crystalline silicon heterostructure to improve the passivation performance for high-efficiency silicon heterojunction solar cells. To accelerate the time-intensive process optimization of many parameters, we applied Bayesian optimization (BO). Consequently, the optimization of six process parameters of HPT was achieved by BO of only 15 cycles and 10 initial random experiments. Furthermore, the effective carrier lifetime after HPT on the optimized experimental conditions became three times higher compared with that before HPT, which certifies that BO is useful for accelerating optimization of the practical process conditions in multidimensional parameter space.
High thermal stability and low driven current achieved by vertical domain wall motion memory with artificial ferromagnet

Published: January 2021

To enhance thermal stability while keeping low driven current is difficult in traditional domain wall (DW) motion devices. The increasing of energy barrier for thermal stability inevitably results in the enhancement of driven current. We numerically investigate depinning field (H
depin) and critical current density (J
c) for DW motion as a function of uniaxial magnetic anisotropy (K
u) in vertical DW motion memory with artificial ferromagnet. It is found that H
depin and J
c show different K
u dependence. The results indicate that it is promising to simultaneously achieve high thermal stability and low driven current in artificial ferromagnet based DW motion devices.
Differences between the composition of surface and inner layers of fly ash particles
Authors: Buryan Petr , Sajdl Petr
Published: January 2021

By studying samples from Czech power plants burning brown coal using X-ray photoelectron spectrometry (XPS) have demonstrated differences in the composition of the ashes in their surface and subsurface layers. The main components of the samples were compounds of aluminum, silicon and oxygen - aluminosilicates. Other elements included sulphur, fluorine and in some cases demonstrably calcium, sodium, magnesium, fluorine and iron. The largest part of the carbon compounds present is the so-called "adventitious carbon", contaminating carbon, i.e. hydrocarbons adsorbed on the surface from the atmosphere. Others come from technology including a small amount of carbides. Distribution of sulphur and iron compounds detected using a short time ion etching is in most cases following: sulphur compounds are concentrated on the surface of ash particles while iron compounds are typically concentrated inside. Differences in composition of surface layers were found to be significant as in the surface composition as in theirs depth profiles. Gas evolution was detected in an ash-water reaction test in which the analysis of the gas has shown that it is mainly about hydrogen and carbon dioxide. Another test with water showed the formation of an incrustation and documented the evolution of gases by the formation of bubbles. The released gases can form explosive mixtures with air, which must be taken into account when removing deposits with a water jet.
Cicha bohaterka codzienności. Rzecz o Alojzie Trauguttównie

Published: January 2021

Pamięć o Alojzie Trauguttównie nie polega – jak by się zdawać mogło – wyłącznie na byciu córką naczelnika powstania styczniowego Romualda Traugutta. Pozostawiła po sobie – jako nauczycielka i logopeda, stosująca nowoczesne metody psychologii wychowawczej, jednobrzmiące wspomnienia znających ja ludzi, została zapamiętana bowiem jako jednostka nie tylko arcyużyteczna społecznie, ale i nadzwyczajnie altruistyczna.Artykuł przypomina najważniejsze punkty węzłowe z biografii Trauguttówny, weryfikując lub ponawiając ustalenia poprzedników, w tym Hanny Muszyńskiej-Hoffmannowej, autorki opowieści biograficznej Panna Trau. Przywołuje się fragmenty reminiscencji zawartych w  memuarach uczennic i  współpracownic Trauguttówny jako świadectw jej szczególnej obecności.Trauguttówna byłą także poetką. Niestety, podpisywała swoje wiersze pseudonimami lub publikowała je anonimowo. W artykule próbuje się dokonywać atrybucji wybranych liryków, m.in. z „Bluszczu” i „Biesiady Literackiej”.
Pensamiento oral y verdad en "El Caguamo", de Eraclio Zepeda
Authors: Maldonado Alcocer Maribel
Published: January 2021

En el presente artículo se analiza el cuento “El Caguamo” del escritor mexicano Eraclio Zepeda, desde una perspectiva epistemológica donde se explica el pensamiento y comportamiento de los personajes, considerando que ellos poseen una conciencia primordialmente oral y no occidental o escrita. Este estudio es de naturaleza hermenéutica y corresponde a la teoría de la interpretación literaria, a través de un marco teórico que proviene de la antropología y la etnoficción. En la conclusión se afirma que el actuar de los personajes puede ser comprendido dentro del pensamiento oral, prueba de esto son las características epistemológicas que ellos tienen y desde las cuales interpretan el mundo que les rodea.

Dentro del analisis se considera que los personajes, en especial el protagonista, poseen un pensamiento preponderantemente oral porque sus acciones, determinaciones, reflexiones y juicios corresponden a las psicodinamicas de la oralidad, las cuales Walter Ong describe y clasifica en su libro titulado: Oralidad y escritura. Tecnologías de la palabra. Por lo tanto, se estima que el cuento de Eraclio Zepeda se puede interpretar como una representacion del pensamiento oral, desde la perspectiva de la cultura mestiza; la cual trata de comprender y de explicar este tipo de conciencia, epistemologicamente completa, a traves de la ficcionalizacion de la misma, a las culturas que no son autoctonas, con el fin de mostrar y engrandecer la complejidad y diversidad cultural, social y epistemica que se puede observar en un pais mestizo como Mexico, a traves del lenguaje literario.
Memoria, ficción y multilingüismo en "El boxeador polaco", un cuento de Eduardo Halfon
Authors: Van Hecke An
Published: January 2021

Este artículo propone analizar el cuento ‘El boxeador polaco’ que forma parte de la colección de cuentos, del mismo título, El boxeador polaco (2008), de Eduardo Halfon. En varios de sus libros, que suelen ser una mezcla de lo ficticio y lo autobiográfico, Halfon desarrolla la problemática de la identidad judía. A veces hay un narrador que no se reconoce en ciertas tradiciones judías, pero que al mismo tiempo percibe lo judío como algo que lleva dentro, lo que se observa sobre todo en el respeto y la admiración por el abuelo. Este abuelo es precisamente uno de los dos protagonistas del cuento ‘El boxeador polaco’. Los juegos sutiles entre las dos voces narrativas –del abuelo y del nieto–, y entre los dos tiempos –el actual en Guatemala y el pasado en Auschwitz–, parecen ser estrategias literarias para enfrentarse a la conocida paradoja del trauma: la imposibilidad de hablar sobre un trauma por un lado, y la fuerza de la lengua como herramienta para curar al traumatizado, por otro (Gilmore, Kilby). ¿Cómo pasar a la literatura lo indecible del trauma? El abuelo rompe el silencio de sesenta años en los que no podía recordar aquel pasado doloroso. Cabe examinar en este contexto el carácter multilingüe del cuento, con referencias al yiddish, al alemán y al polaco. Es nuestro objetivo tratar de entender cómo Halfon maneja la difícil relación no solo entre memoria y ficción, sino también entre lengua e identidad.
Releer a los clásicos desde el libro álbum: análisis de Lazarillo
Authors: Rivera Jurado Paula
Published: January 2021

¿Cómo enfrentar al lector en formación a la lectura de aquellas obras que integran el canon histórico-literario de la escuela? Bien es cierto que la lectura de las grandes obras canónicas requiere de cierta madurez lingüística y cognitiva, pero, aun así, existen diversas estrategias didácticas –entre ellas, las adaptaciones- para no privar a niños y adolescentes del goce de los grandes títulos. Así pues, se presenta una reseña sobre la adaptación del clásico Lazarillo de Tormes al libro álbum Lazarillo (2019, Diego Pun Ediciones). El análisis de esta versión moderna y actualizada del pícaro pretende hacer hincapié en el concepto de adaptación como punto de encuentro entre la teoría literaria y la teoría didáctico-cognitiva, poniendo de relieve a las adaptaciones como estrategia de confluencia entre el disfrute de los textos clásicos y la competencia lectora y literaria del alumnado en formación.

Then, the success increased to 20 (100%) students in cycle 2. In other words, all students can achieve learning achievement in cycle 2.
Efektifitas Penggunaan Aplikasi berbasis Android Sebagai Dampak dari Penyebaran Covid-19
Authors: Astuti Natalia Tri
Published: January 2021

The background of this research is distance learning which utilizes media in the form of android-based applications in connection with the global covid-19 pandemic experienced by various countries, one of which is Indonesia. This condition affects the movement of various sectors, including the education sector. After going through several months with this global pandemic condition, with all teaching-learning activities from various levels carried out from home, the use of appropriate methods is a very serious concern. Learning from home is one way that is expected to be able to suppress the spread of covid-19. Many distance learning media are available, so it is necessary to know the effectiveness of using these media to be used in distance learning. The method used in this research was qualitative-quantitative with a sample of 30 students chosen at random with the student record "technology literate". The data collection method was carried out through a questionnaire using electronic media and internet networks. The results of this research indicate that not all android-based applications can be used effectively in distance learning.

Al2O3 layers were deposited onto electrodes by atomic layer deposition. Solubility and electron-transport blocking were tested. Films deposited onto fluorine-doped tin oxide (FTO, F:SnO2/glass) substrates blocked electron transfer to redox couples (ferricyanide/ferrocyanide) in aqueous media. However, these films were rapidly dissolved in 1 M NaOH (≈100 nm/h). The dissolution was slower in 1 M H2SO4 (1 nm/h) but after 24 h the blocking behaviour was entirely lost. The optimal stability was reached at pH 7.2 where no changes were found up to 24 h and even after 168 h of exposure the changes in the blocking behaviour were still minimal. This behaviour was also observed for protection against direct reduction of FTO.
