Authors: Poczta Joanna , Almeida Nuno , Rozmiarek Mateusz , Młodzik Maciej , Malchrowicz-Mośko Ewa
Published: May 2021

Running has been very popular for years, especially in organized mass runs. Various running events take place all over the world, at different distances and locations, including charity running events. However, there has not been any research on the social impact of these events on participants to date. This article/paper is an attempt to remedy this situation. The authors conducted their research by the diagnostic survey method using standardized interview technique during the 6th Santa Claus Run organized in Poznan on the day of Santa Claus. A sample of 136 runners: 49 male respondents and 87 female respondents participated in the event voluntarily and completed a questionnaire. Therefore, the main goal of the study was to recognize the relationship between the lifestyles of men and women in the context of participation in a charity running event, in order to evaluate the differences between them. The specific goal was to discern the motives to take part in such kind of an event, as well as to find out what influence the participation in a charity run has on the respondents, both those leading an active and passive lifestyle. The most important result and the only one statistically significant difference in the conducted study was the indication that women have more empathy and participate more often than men in charity runs.

Published: May 2021

Complex systems consist of multiple machines that are designed with a certain extent of redundancy to control any unanticipated events. The productivity of complex systems is highly affected by unexpected simultaneous machine failures due to overrunning of machines, improper maintenance, and natural characteristics. We proposed realistic configurations with multiple machines having several flexibilities to handle the above issues. The objectives of the proposed model are to reduce simultaneous machine failures by slowing down the pace of degradation of machines, to improve the average occurrence of the first failure time of machines, and to decrease the loss of production. An approach has been developed using each machine’s degradation information to predict the machine’s residual life based on which the job adjustment strategy where machines with a lower health status will be given a high number of jobs to perform is proposed. This approach is validated by applying it in a fabric weaving industry as a real-world case study under different scenarios and the performance is compared with two other key benchmark strategies.

Authors: Kim Ji-Myong , Bae Junseo , Son Seunghyun , Son Kiyoung , Yum Sang-Guk
Published: May 2021

This study goals to develop a model for predicting financial loss at construction sites using a deep learning algorithm to reduce and prevent the risk of financial loss at construction sites. Lately, as the construction of high-rise buildings and complex buildings increases and the scale of construction sites surges, the severity and frequency of accidents occurring at construction sites are swelling, and financial losses are also snowballing. Singularly, as natural disasters rise and construction projects in urban areas increase, the risk of financial loss for construction sites is mounting. Thus, a financial loss prediction model is desired to mitigate and manage the risk of such financial loss for maintainable and effective construction project management. This study reflects the financial loss incurred at the actual construction sites by collecting claim payout data from a major South Korean insurance company. A deep learning algorithm was presented in order to develop an objective and scientific prediction model. The results and framework of this study provide critical guidance on financial loss management necessary for sustainable and successful construction project management and can be used as a reference for various other construction project management studies.
Nature Ideas Exchange: Education of Sustainable Business Principles Based on Parallels with Forest Ecosystem
Authors: Macháčková Karolina , Zelený Jiří , Kolářová Dana , Vinš Zbyněk
Published: May 2021

Arne Næss considered nature the best source of knowledge and regarded the economists as morally responsible for the ecological crisis. Therefore, this research focused on students of economic fields at the university level. The experimental group (n = 236) led by a teacher-as-researcher completed a Business Economic course by forest workshops for one semester because the sustainability principles can be very well explained and observed on examples of forest fauna and flora and then applied in managerial practice. Many similarities were found between forest and business principles (optimal growth rate, teamwork, cooperation models, parasitism). This paper aimed to identify if students’ proficiency in applying sustainable mindset from a forest ecosystem to practice increased. The achievement test compared outcomes of the experimental and control group (n = 190) of students. Based on statistical testing, it can be stated that the experimental intervention led to better results compared to the control group. For issues in which no suitable parallel with the forest ecosystem was found and were therefore explained according to the textbook, group (E) did not perform better than group (C). The methodology is based on qualitative and quantitative research, a mixed-methods approach.

Decision-makers, planners and administrators involved in different policy domains at different governance levels face the important challenge of fostering more balanced, sustainable and territorially integrated development. Well-designed, multi-level, multi-sector and multi-actor governance arrangements can play a key role in this process through orchestrating the interplay between different spheres, activities, actors and interests. In this paper, we examine the role of spatial planning in improving the relations between rural, peri-urban and urban areas. We analyse the strengths and limitations of spatial planning and explore the connections with territorial development. The methodology used for this analysis combines regional case studies in seven European locations—Ede, Frankfurt/Rhein-Main, Styria/Graz, Helsinki, Lisbon, Lucca and Mid Wales, with rapid appraisals, the analysis of published data, expert judgement and triangulation. We ask under which conditions spatial planning can induce more balanced, sustainable territorial relations, and look at the contribution planning can make to achieving sustainable development goals. The problem of ineffective (or toothless) plan implementation provides the entry point into the analysis and discussion. We illustrate why mutually beneficial relations between urban, peri-urban and rural communities (and territories) cannot simply be planned. Instead, these relationships need to be supported by strategies, policy instruments and governance arrangements that foster synergies between different actors and activities. The planning process itself needs to become more transparent and participatory. We conclude that the questions addressed in this article in an exploratory fashion merit further research especially as a more sustainable and territorially integrated development is becoming increasingly important in European policy making.

Published: May 2021

The buildings sector is one of the least sustainable activities in the world, accounting for around 40% of the total global energy demand. With the aim to reduce the environmental impact of this sector, the use of renewable energy sources coupled with energy storage systems in buildings has been investigated in recent years. Innovative solutions for cooling, heating, and domestic hot water in buildings can contribute to the buildings’ decarbonization by achieving a reduction of building electrical consumption needed to keep comfortable conditions. However, the environmental impact of a new system is not only related to its electrical consumption from the grid, but also to the environmental load produced in the manufacturing and disposal stages of system components. This study investigates the environmental impact of an innovative system proposed for residential buildings in Mediterranean climate through a life cycle assessment. The results show that, due to the complexity of the system, the manufacturing and disposal stages have a high environmental impact, which is not compensated by the reduction of the impact during the operational stage. A parametric study was also performed to investigate the effect of the design of the storage system on the overall system impact.
A New Sentence-Based Interpretative Topic Modeling and Automatic Topic Labeling
Authors: Kozbagarov Olzhas , Mussabayev Rustam , Mladenovic Nenad
Published: May 2021

This article presents a new conceptual approach for the interpretative topic modeling problem. It uses sentences as basic units of analysis, instead of words or n-grams, which are commonly used in the standard approaches.The proposed approach’s specifics are using sentence probability evaluations within the text corpus and clustering of sentence embeddings. The topic model estimates discrete distributions of sentence occurrences within topics and discrete distributions of topic occurrence within the text. Our approach provides the possibility of explicit interpretation of topics since sentences, unlike words, are more informative and have complete grammatical and semantic constructions inside. The method for automatic topic labeling is also provided. Contextual embeddings based on the BERT model are used to obtain corresponding sentence embeddings for their subsequent analysis. Moreover, our approach allows big data processing and shows the possibility of utilizing the combination of internal and external knowledge sources in the process of topic modeling. The internal knowledge source is represented by the text corpus itself and often it is a single knowledge source in the traditional topic modeling approaches. The external knowledge source is represented by the BERT, a machine learning model which was preliminarily trained on a huge amount of textual data and is used for generating the context-dependent sentence embeddings.
Experimental Disproof of a Manga Character Construction Model
Authors: Matsui Tetsuya , Gunji Yukio-Pegio
Published: May 2021

In prior works, the impression of elements of virtual agents/manga character and the overall impression of virtual agents/manga character were considered completely symmetric. In this work, we conducted a preliminary experiment to develop a system that creates designs of virtual agents depending on a text. In this experiment, the participants read the text and chose the image of an agent and social group that resembled their mental image. We introduced the lattice derived by the rough set induction method to suggest the model to analyze the mental image. In this model, we constructed the lattice from two interpretations to evaluate the complexity of the mental image generation process. As a result, the lattices derived by social groups and appearance were non-Boolean; however, those derived by two kinds of design features were not non-Boolean. This result shows that the mental appearance and social images cannot be combined voluntarily. This result showed that it is not symmetric between each element of virtual agents/manga character and overall virtual agents/manga character.

Published: May 2021

The Paeonia emodi (P. emodi)-mediated iron oxide nanoparticles (Fe2O3 NPs) were screened for in-vitro and in-vivo antibacterial activity against the Staphylococcus aureus (S. aureus) (ATCC #: 6538) and Escherichia coli (E. coli) (ATCC #:15224). The synthesized Fe2O3 NPs were characterized via nitrogen adsorption-desorption process, X-ray diffractometer (XRD), transmission and scanning electron microscopies (TEM and SEM), energy dispersive X-ray (EDX) and Fourier transform infrared (FTIR) spectroscopies. The SBET was found to be 94.65 m2/g with pore size of 2.99 nm, whereas the average crystallite and particles size are 23 and 27.64 nm, respectively. The 4 μg/mL is the MIC that inhibits the growth of E. coli, whereas those for S. aureus are below the detection limit (<1.76 μg/mL). The tolerance limit of the mice model was inspected by injecting different concentration of Fe2O3 NPs and bacteria suspensions. The 14 ppm suspension was the tolerated dose and the concentration above were proved lethal. The most severe infection was induced in mice with injection of 3 × 107 CFUs of both bacteria, while the inoculation of higher concentrations of bacterial suspensions resulted in the mice’s death. The histopathological and hematological studies reveals that the no/negligible infection was found in the mice exposed to the simultaneous inoculation of Fe2O3 NPs (14 ppm) and bacterial suspensions (3 × 107 CFUs).

Published: May 2021

In this paper we present the most recent observations of gravitational waves (GWs) by LIGO and Virgo detectors. We also discuss contributions of the recent Nobel prize winner, Sir Roger Penrose to understanding gravitational radiation and black holes (BHs). We make a short introduction to GW phenomenon in general relativity (GR) and we present main sources of detectable GW signals. We describe the laser interferometric detectors that made the first observations of GWs. We briefly discuss the first direct detection of GW signal that originated from a merger of two BHs and the first detection of GW signal form merger of two neutron stars (NSs). Finally we present in more detail the observations of GW signals made during the first half of the most recent observing run of the LIGO and Virgo projects. Finally we present prospects for future GW observations.
The SuSA Model for Neutrino Oscillation Experiments: From Quasielastic Scattering to the Resonance Region
Authors: Barbaro Maria B. , De Pace Arturo , Fiume Luisa
Published: May 2021

High-precision studies of Beyond-Standard-Model physics through accelerator-based neutrino oscillation experiments require a very accurate description of neutrino–nucleus cross-sections in a broad energy region, going from quasielastic scattering up to deep, inelastic scattering. In this work, we focus on the following processes: quasielastic scattering, two-particle-two-hole excitations, and the excitation of the first (Delta) and second (Roper) resonances of the nucleon. The nuclear model is fully relativistic and includes both one- and two-body currents. We compare our results with recent T2K and MicroBooNE data on carbon and argon targets, and present predictions for DUNE kinematics.
Loperamide Inhibits Replication of Severe Fever with Thrombocytopenia Syndrome Virus
Authors: Urata Shuzo , Yasuda Jiro , Iwasaki Masaharu
Published: May 2021

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease caused by the SFTS virus (SFTSV). SFTS is mainly prevalent in East Asia. It has a mortality rate of up to 30%, and there is no approved treatment against the disease. In this study, we evaluated the effect of loperamide, an antidiarrheal and antihyperalgesic agent, on the propagation of SFTSV in a cell culture system. Methods: SFTSV-infected human cell lines were exposed to loperamide, and viral titers were evaluated. To clarify the mode of action of loperamide, several chemical compounds having shared targets with loperamide were used. Calcium imaging was also performed to understand whether loperamide treatment affected calcium influx. Results: Loperamide inhibited SFTSV propagation in several cell lines. It inhibited SFTSV in the post-entry step and restricted calcium influx into the cell. Furthermore, nifedipine, a calcium channel inhibitor, also blocked post-entry step of SFTSV infection. Conclusions: Loperamide inhibits SFTSV propagation mainly by restraining calcium influx into the cytoplasm. This indicates that loperamide, a Food and Drug Administration (FDA)-approved drug, has the potential for being used as a treatment option against SFTS.

Published: May 2021

Despite research conducted worldwide, there is no treatment specifically targeting SARS-CoV-2 infection with efficacy proven by randomized controlled trials. A chance for a breakthrough is vaccinating most of the global population. Public opinion surveys on vaccine hesitancy prompted our team to investigate Polish healthcare workers’ (HCWs) attitudes towards the SARS-CoV-2 and influenza vaccinations. In-person and online surveys of HCWs: doctors, nurses, medical students, and other allied health professionals (n = 419) were conducted between 14 September 2020 and 5 November 2020. In our study, 68.7% of respondents would like to be vaccinated against COVID-19. The safety and efficacy of COVID-19 vaccinations would persuade 86.3% of hesitant and those who would refuse to be vaccinated. 3.1% of all respondents claimed that no argument would convince them to get vaccinated. 61.6% of respondents declared a willingness to receive an influenza vaccination, of which 83.3% were also inclined to receive COVID-19 vaccinations. Although most respondents—62.5% (262/419) indicated they trusted in the influenza vaccine more, more respondents intended to get vaccinated against COVID-19 in the 2020/2021 season. The study is limited by its nonrandom sample of HCWs but provides a preliminary description of attitudes towards SARS-CoV-2 vaccination.

Published: May 2021

In China, there are two categories of vaccines available from the Chinese Center for Disease Control and associated public health agencies. Extended Program of Immunization (EPI) vaccines are government-funded and non-EPI vaccines are voluntary and paid for out-of-pocket. The government plans to transition some non-EPI vaccines to EPI in the coming years, which may burden public health system capacity, particularly in terms of budget, workforce, supply chains, and information systems. Our study explored vaccinator and caregiver perspectives on introducing non-EPI vaccines into routine immunization and perceived facilitators and barriers affecting this transition. We conducted a qualitative study from a realist perspective, analysing semi-structured interviews with 26 vaccination providers and 160 caregivers in three provinces, selected to represent regional socioeconomic disparities across Eastern, Central, and Western China. Data were analysed thematically, using deductive and inductive coding. Most participants were positive about adding vaccines to the national schedule. Candidate EPI vaccines most frequently recommended by participants were varicella, mumps vaccine, and hand–foot–mouth disease. Providers generally considered existing workspaces, cold-chain equipment, and funding sufficient, but described frontline staffing and vaccine information systems as requiring improvement. This is the first qualitative study to explore interest, barriers, and facilitators related to adding vaccines to China’s national schedule from provider and caregiver perspectives. Findings can inform government efforts to introduce additional vaccines, by including efforts to retain and recruit vaccine programme staff and implement whole-process data management and health information systems that allow unified nationwide data collection and sharing.

This study investigates changes in willingness to vaccinate against COVID-19 and the effect of the extended restrictions in metropolitan Victoria on this change. Longitudinal and repeated cross-sectional data were collected from online surveys distributed in April, between July and August, and December 2020. Australian adults who were ≥18 years old were recruited through email lists, social media networks, and paid Facebook advertisement. Willingness to vaccinate against COVID-19 was self-reported. The results showed that participants were more willing to vaccinate if the vaccine was safe at survey 1 (longitudinal: adjusted OR (aOR) = 1.88, 95%CI = 1.38, 2.56; cross-sectional: aOR = 3.73, 95%CI = 2.55, 5.45) and survey 2 (longitudinal: aOR = 1.54, 95%CI = 1.19, 2.00; cross-sectional: aOR = 2.48, 1.67, 3.67), compared to survey 3. The change in willingness to vaccinate if the vaccine was safe and effective was not significant for those in Metropolitan Victoria; but was for those living in other Australian locations at survey 1 (OR = 2.13, 95%CI = 1.64, 2.76) and survey 2 (OR = 1.62, 95%CI = 1.30, 2.01), compared to survey 3. Willingness to vaccinate even if a vaccine had not been proven safe decreased at survey 3 (OR = 2.02, 95%CI = 1.14, 3.57) for those living in Metropolitan Victoria. In conclusion willingness to vaccinate against COVID-19 decreased over time among Australians, except for those living in metropolitan Victoria, where an additional strict and prolonged lockdown was implemented around the time of survey 2. Either the experience of the lockdown, or the presence of the COVID-19 virus itself had a positive influence on participants’ willingness to vaccinate, even if such a vaccine was not yet proven to be safe and effective.
Fixture for High-Frequency Viscoelastic Transfer Path Analysis in Application to Elastomer Sealing Rings in Electric Motors
Authors: Schnell Michael , Gradtke Marvin , Gauterin Frank
Published: May 2021

In this paper, the frequency response functions of rubber o-rings are investigated. A growing trend is the application of electric motors in vehicle powertrains. Electric motors exhibit a different kind of structural dynamic excitation, compared to conventional internal combustion engines. Especially the excitation frequency is multiple times higher, as in combustion engines. This increased excitation frequency is a novel requirement on materials and their modelling in simulations. For this case, a novel fixture is introduced, which constrains the rubber o-ring components in their designated conditions and which allows to perform a Transfer-Path-Analysis up to a frequency of 6.5 kHz. The evaluation of the results shows a high coherence throughout the considered frequency range, while using a high-frequency miniature shaker. The structural resonances are clearly visible and the signal noise is low. This proves the suitability of the presented fixture, in combination with the high-frequency miniature shaker. The results presented and the fixture itself serve as a basis for further work and developments.

Published: May 2021

To improve knowledge of this matter, the potential application of two gridded meteorological products (GMPs), the China Meteorological Assimilation Driving Datasets for the SWAT model (CMADS) and Climate Forecast System Reanalysis (CFSR), are compared for the first time with data from ground-based meteorological stations over 6 years, from 2008 to 2013, over the Cau River basin (CRB), northern Vietnam. Statistical indicators and the Soil and Water Assessment Tool (SWAT) model are employed to investigate the hydrological performances of the GMPs against the data of 17 rain gauges distributed across the CRB. The results show that there are strong correlations between the temperature reanalysis products in both CMADS and CFSR and those obtained from the ground-based observations (the correlation coefficients range from 0.92 to 0.97). The CFSR data overestimate precipitation (percentage bias approximately 99%) at both daily and monthly scales, whereas the CMADS product performs better, with obvious differences (compared to the ground-based observations) in high-terrain areas. Regarding the simulated river flows, CFSR-SWAT produced “unsatisfactory”, while CMADS-SWAT (R2 > 0.76 and NSE > 0.78) performs better than CFSR-SWAT on the monthly scale. This assessment of the applicative potential of GMPs, especially CMADS, may further provide an additional rapid alternative for water resource research and management in basins with similar hydro-meteorological conditions.
Combined Dispatching of Hydropower and Wind Power Based on the Hedging Theory

Published: May 2021

In order to improve the utilization rate of water resources in the flood season of the reservoir effectively and promote wind power consumption, this paper proposes an optimization model for the combined dispatching of wind power and hydropower based on the hedging theory. First, the conflicting relationship between the water storage benefits of hydropower stations, flood control risks, and the joint output of hydropower and wind power in joint dispatching is studied. The introduction of hedging theory divides the combined dispatching of wind power and hydropower into a two-stage dispatching problem including the decision-making stage and the remaining stage; Second, considering the uncertainty of water forecasting and wind power forecasting, a multi-objective optimal dispatching model of hydropower and wind power based on hedging theory is constructed. This model aims to minimize flood control risks, maximize water storage benefits, and minimize wind power and hydropower combined power output volatility. Finally, the non-dominated sorting genetic algorithm (NSGA2) is used to solve the specific examples. The results show that the model built in the article controls the flood control risk at each time period not to be higher than 1.63 × 10−3 (the flood control standard corresponding to the flood control risk in 50 years is 0.006). Additionally, the water level of the reservoir increased from the flood limit water level (583.00 m) to 583.70 m. It greatly increases the water storage capacity and effectively improves the utilization rate of water resources. At the same time, the optimized scheduling scheme reduced the peak-valley difference of joint output from 125.00 MW to 35.66 MW, and the peak-valley difference was greatly reduced. It effectively improves the volatility of wind power. The validity of the model is verified, and the obtained scheme can provide decision-making for the joint dispatch scheme of hydropower and wind power.

Published: May 2021

The article is meant to analyze the process of internalization of the educational policy in the Russian Federation. Internationalization of the Russian education system is becoming one of the main trends in state policy of the Russian Federation, as evidenced by the recent launch of such programs as "5–100" and "Development of the Export Potential of the Russian System of Education". The authors believe that it is necessary to further align Russian and international educational standards (both Western and Eastern/Asian), create and develop applied bachelor’s degrees, as well as educational programs aimed at achieving the UN sustainable development goals (SDGs), which will be in demand in any country across the world. In this regard, the authors propose a number of measures that would contribute to achieving the strategic goals of the Russian Federation in the area of education services export, including joint programs of Russian, Chinese, Singaporean and Hong Kong universities in natural sciences and information and communication technologies. Taking into account Russia’s world leadership in the development of COVID-19 vaccine and studies related to the eff ective treatment of this disease, it would be advisable to adopt appropriate recommendations for the universities where foreign citizens are studying, explaining the risks of coronavirus infection spread during their studies, the procedure of medical insurance for students and guarantees of Russian universities in case of an appropriate insurance event.

A oftalmologia veterinária abrange o diagnóstico das alterações oculares, perioculares e retrobulbares primárias, e também suas manifestações sistêmicas e secundárias, o que se torna possível a partir da avaliação completa do bulbo ocular, órbita e anexos por meio do exame oftálmico completo e de exames complementares. Dentre os exames de imagens que auxiliam no diagnóstico das afecções oculares, a ultrassonografia está entre os exames de imagem mais utilizados na rotina veterinária, auxiliando na observação de anormalidades retrobulbares e na avaliação das estruturas bulbares na presença de opacificação de meios transparentes, por exemplo. Além da ultrassonografia, existem outras modalidades de exames, dentre eles a tomografia computadorizada, ressonância magnética, angiografia, microscopia especular, tomografia de coerência óptica (OCT) e angiografia por tomografia de coerência óptica (OCT-A).  Em virtude dos avanços tecnológicos na obtenção de imagens, a avaliação globo ocular e das estruturas orbitárias pode ser realizada com maior precisão, o que favorece o diagnóstico e a escolha terapêutica adequada. Objetiva-se com esta revisão enumerar os exames disponíveis, suas principais indicações, bem como sua aplicabilidade e estudos em animais domésticos.
A Case Study on Reducing Setup Time Using SMED on a Turning Line
Authors: ŞAHİN Ramazan , KOLOĞLU Aycan
Published: May 2021

Today, manufacturers must meet customer demands in a shorter time with the best quality and lowest cost to survive in competitive environment. One way to achieve this is to reduce production costs by eliminating waste activities in a production system. Machine adjustment processes are the activities that do not create value, and Single Minute Exchange of Dies (SMED), lean manufacturing tool, has been developed to reduce these activities. In this paper we have performed a case study in a bearing manufacturing company to reduce the machine setup time on turning line using the SMED. The emphasis is given to both transferring internal activities into external ones as many as possible and minimizing the internal ones. The main results attained from the study indicate that the machine setup times were reduced more than 45% for the turning line. Consequently, machine capacities can be significantly increased by the application of SMED method.

This objective is to contribute to internal control of the Requests for Access to Information that are sent to the dependencies, entities, auxiliary bodies, and, escrows that integrate State Public Administration. It also follows up that the Requests are attended to and are fulfilled within the terms established by the Law of Transparency and Access to Public Information for the State of Oaxaca (LGTAIPO). The web system has the following functionalities: a history of requests and responses, it allows the use of different response formats; it generates reports based on a period defined by the user; it allows you to schedule meetings, and it follows up if necessary. In addition, it has a Request, Dependencies module and an internal chat so that they can communicate with each other. The web system was based on the agile development model using Extreme Programming (XP) and the MySql database manager was used.

In this work, an evaluation of the energy in a start-stop process is made by analyzing the generated irreversibilities in a refrigeration system by mechanical vapor compression with R-134a refrigerant at a flow of 1.0 L / s. This system is installed in the LABINTHAP of the SEPI-ESIME-IPN. For this analysis, there is software that captures data on the pressures and temperatures from the refrigerant at the inlet and outlet of the evaporator, compressor, condenser, and expansion valve at oneminute intervals. For the analysis of the generated irreversibilities, the first and second laws of thermodynamics were used. And, in the process evaluation of stopping and starting, it was shown that the compressor sets a trend of higher energy consumption, so a process of regulation of the refrigeration system by mechanical compression of steam is proposed.

Greater amount of energy consumed in wineries is used for cooling and humidifying of the interior, for this reason the correct design of energy efficient wineries has become an important issue for winemaking countries. The purpose of the design of buildings that require less or no energy to achieve controlled conditions of the indoor hygrothermal environment for production and aging of wine, allowed to formulate the objective of this work, which was to evaluate six models of wineries with bioclimatic design located in El Valle de Guadalupe, Baja California from data on thermal performance (indoor temperature and relative humidity) and energy consumption (kWh and degrees-hour), obtained by dynamic thermal simulation. The zone of the study was characterized, based on the review of previous studies optimum temperature ranges were defined for aging and wine production. A basic model of a winemaking building was designed to which bioclimatic strategies were applied. The results obtained allowed to suggest the best bioclimatic design options for this type of buildings.

The history of the brick is the history of civilization, the architecture began when 2 bricks were joined. Brick is an older man-made building material. (W. P. Campbell, 2004 and Sánchez, 2013) he objective of this work is to identify the brick manufacturing production process in the city of Ciudad Juarez through the application of the DMAIC methodology. The research work is based on an exploratory sampling with visits to the most important production areas, specifically at km 20 in Ciudad Juárez Chih. observing the manufacturing process from the mixing of the clays to the firing of the units in the oven. Currently it has been found that the wooden mold only allows to obtain 3 bricks and the mold could be improved to double the production, in addition a table could be adapted that makes it easier for the worker to place the mold without having to bend down. It has been found that there is variability in the dimensions of the bricks between one production and another, verifying the dimensions of the 1st burning in January. Analyzing the production of 500 raw bricks in a 6-hour day, taking 5 products every hour.

Oregano is a plant with many nutritional and medicinal properties; there are also other applications in the chemical industry. In this work, the drying kinetics of oregano leaves are studied using a cabinet-type dryer with and without a forced convention, open sun drying, and indirect solar drying. The samples had an initial moisture content of 80 % and the final content of 9 %. The results indicate that indirect solar drying provides better control of operating conditions and greater protection against temperature effects, producing better quality in the dry product. The time required to reach the equilibrium moisture content in all experiments ranged from 375 to 600 min. The data were also adjusted to various mathematical models, resulting In Weibull, Logarithmic, and Page, which best represent the drying behavior of oregano leaves. The statistics used for indirect solar dryer are R2 of 0.9969, 0.9968, and 0.9945, X2 of 0.0363, 0.0363 and 0.0599 respectively.

Sin importar el tamaño de la empresa, el crédito es fundamental para el crecimiento y modernización productiva. La escasez crediticia puede determinar el fracaso y cierre. Las microempresas generalmente no son sujetas de crédito bancario. Esta insolvencia es cubierta por canales financieros formales e informales, sin embargo, la mayoría de estas alternativas tienen la característica de proporcionar recursos escasos y caros, provocando el nulo crecimiento de estos negocios.
El límite del desarrollo del sistema capitalista

Published: May 2021

Las continuas crisis que se han suscitando a escala internacional han puesto en tela de juicio las "recetas" ortodoxas de crecimiento-desarrollo que pregonan, usando como plataforma operativa a los organismos financieros internacionales, las dominadas economías desarrolladas. Analistas y pensadores contemporáneos publicitan "los logros cortoplacistas" económicos logrados por las aclamadas economías subdesarrolladas en función de la puesta en marcha de prescripciones heterodoxas rotuladas como keynesianas. El ensayo intentará analizar cómo ambas posturas confunden crecimiento con desarrollo y que el verdadero paradigma de desarrollo se debería pensar a partir de un cambio del sistema en su totalidad y no con propuestas correctoras dentro del sistema.
Representaciones de la violencia contra la mujer en la prensa chilena
Authors: Olivares Ramirez Yanira
Published: May 2021

Este artículo se centra en los encuadres que los medios de comunicación le otorgan a sucesos de violencia contra la mujer en Chile. Para ello, la investigación ofrece un análisis de contenido a la prensa escrita chilena, focalizándose en el tratamiento informativo y la cobertura mediática otorgada al feminicidio frustrado en contra de Nabila Rifo, hecho ocurrido el año 2016. Se observó una gran cobertura y relevancia al caso, lo que sugiere un posicionamiento de la violencia contra la mujer en la agenda mediática chilena. No obstante, el tratamiento informativo demostró diversas falencias (rupturas epistemológicas, ausencia de contexto, sobreexposición de la víctima, móviles y justificaciones, exigua incorporación de fuentes especializadas en el tema, escasa información educativa, encuadres morbosos, entre otros). En consecuencia, se propone que, a pesar de la visibilización del tema, el tratamiento informativo en la prensa chilena utiliza enfoques que no incorporan una perspectiva de género, facilitando un segundo espacio de violencia para la víctima.
La extrañeza en la escritura
Authors: Souyris Oportot Lorena
Published: May 2021

El presente artículo intenta poner en tensión el discurso de la institucionalización del saber legitimado bajo designaciones canónicas en el lenguaje. En tal sentido, a través de una  extrañeza en la escritura y a partir de la obra de Maurice Blanchot, se someterá a juicio la violencia normativa inscrita en las retóricas circunscritas en las formas del lenguaje. Todo ello, con el fin de  proponer, a partir de la escritura fragmentaria, una “plusvalía” de la voz narradora que se manifiesta como exceso en la escritura. La idea es, pues, posibilitar la puesta en escena de un "ínter-dit" (entre-decir) como un área que se abre a una estetización de la aporía que no sólo constituye una "poética" del discurso crítico, sino que también se ofrezca a una comprensión inacabada que deconstruya la explicación cerrada.

Manual harvesting of large area fruits is inefficient, which consumes manpower and resources. Mechanized harvesting is the inevitable trend of fruit harvest. Vibration harvesting is one of the important forms in terms of fruit mechanized harvesting. According to the different striking parts of fruit trees, the vibration modes were classified as trunk, crown, and branch types. The harvesting efficiency of fruit is an important index to measure the quality of all fruit harvesting machines. The reduction of fruit damage is considered in the harvesting of vulnerable fruits. In this study, the development of vibration harvesting technologies were studied in terms of vibration mode. The development of fruit damage, harvesting efficiency, and fruit tree modeling were discussed. Finally, the development direction of fruit vibration mechanized harvesting was looked forward. Machinery instead of manpower, fully mechanized harvesting is the inevitable development direction of fruit harvesting.
