Authors: Covarrubias Gordillo Carlos Andrés , Medellín Rodríguez Francisco Javier , Ávila Orta Carlos Alberto , Martínez Colunga Juan Guillermo , Cruz Delgado Víctor Javier
Published: May 2022

Después de las primeras décadas de investigación, los avances en el área de la nanotecnología comienzan a reflejarse como productos y dispositivos de uso común en la sociedad. El concepto de nanotecnología y sus principios prometen ser una solución para abordar algunos de los problemas de desarrollo más importantes en el mundo: por ejemplo, el acceso igualitario a fuentes asequibles de energía renovable mediante el aprovechamiento de la energía solar. Sólo en México, 56.4% de las viviendas no tiene acceso a un servicio de agua caliente, el cual trae diversos beneficios que no siempre son valorados por la sociedad en el medio urbano. Actualmente, por medio de la aplicación de la nanotecnología, se han construido calentadores solares de agua de plástico con nanopartículas conductoras, lo que resulta de interés por sus propiedades únicas, como una alta resistencia y tiempo de vida, ligereza, y el ser limpios al contacto con el agua, económicos y con la capacidad de transferir el calor con eficiencia. En este artículo, se aborda el concepto de nanotecnología y su aplicación para fabricar calentadores solares de agua que propician una forma más limpia y asequible de proveer energía, priorizando el desarrollo social y humano de manera igualitaria.

Hegemonía y crisis de hegemonía en Colombia, debate abierto sobre la historia
Authors: Bautista Bautista Sandra Carolina
Published: May 2022

Es poca la bibliografía especializada que aborda el análisis del Estado en Colombia desde la perspectiva gramsciana. El artículo se inscribe en este campo y discute con las posturas que, a partir de la prolongación del conflicto armado, niegan la existencia de hegemonía en este país latinoamericano. Para ello se realiza un análisis histórico entre 1958 y 1991 desarrollando la categoría de proceso hegemónico, entendida como la articulación conflictiva entre momentos de hegemonía estable y momentos de crisis orgánica abierta. Así, aparece la necesidad de comprender la hegemonía y la crisis no tanto como estados puros observables en la realidad que se niegan mutuamente, para asumirlos más bien como flujos históricos configurados en ambos casos por la violencia del conflicto armado.
De la geopolítica y la política en tiempos de caos sistémico: una mirada desde América Latina/Abya Yala
Authors: Licio Caetano do Rego Monteiro Licio , Porto-Gonçalves Carlos Walter
Published: May 2022

El propósito de este artículo es comenzar una discusión sobre el papel de Abya Yala. América Latina en el escenario geopolítico contemporáneo. Con este fin, busca volver a l formación histórica y territorial del continente en sus momentos clave, demostrando la relevancia de la conquista colonial del continente americano para la proyección geopolítica europea en su relación con Asia (siglos XV-XIX) y el peso de esta larga duración al observar la ascensión china y sus repercusiones continentales y globales actuales. Creemos que una mirada geopolítica tradicional, a gran escala y centrada en las grandes potencias económicas y en los estados, debe enfrentarse a otros puntos de vista y escalas que buscan reconocer el papel activo de los grupos / clases sociales en las diferentes relaciones sociales y de poder que marcan y sus escalas, que redefinen los eventos de la geopolítica global. El articulo está dividido en tres partes, a saber, (1) un análisis de la constitución del sistema mundo y de la importancia de la América para comprehender ese sistema, (2) una reinterpretación de la colonialidad que ha sobrevivido al término del colonialismo e (3) a emergencia política de la América /Abya Yala Profunda.
A Multicentric Survey of Indian Medical Students about their Knowledge and Perception on Antimicrobial Stewardship

Published: May 2022

Antimicrobial stewardship (AMS) and appropriate infection prevention practices are essential to decrease the rising trend of antimicrobial resistance (AMR). Good antimicrobial prescribing habits formed early in the medical career can make a paradigm shift in combating the menace of AMR. Scarce data is available about the knowledge and perceptions of Indian undergraduates on AMS. This study was planned to analyse the knowledge, attitude and perceptions (KAP) of Indian medical undergraduates on rational antimicrobial prescribing, so that the lacunae in the training curriculum can be identified and addressed effectively. A cross-sectional questionnaire-based survey was carried out, on the pre-final and final year medical students (6th to 9th semester) from six medical colleges across different states of India. A scoring system was used to rate the knowledge, attitude and perceptions of the respondents as poor, average, or good. A total of 1505 students (83.61%) participated in the survey. Majority of the students (81.7%) from all medical colleges favoured more education on antimicrobials and to incorporate AMS in the undergraduate curriculum through integrated teaching. The results showed that overall, 70.9% students had a “good” score for knowledge on antimicrobial use, whereas only 55% scored “good” for being confident in rational antimicrobial prescribing. Surprisingly, only 56.5% correct responses for knowledge on selection of broad-spectrum antibiotics over narrow-spectrum antibiotics were recorded in our study. Most of the students (79.9%) were conscious that irrational prescribing can result to AMR. On the other hand, 54.9% students believed that the supply of new antimicrobials would take care of AMR eventually. 78.1% of our students believed that they were confident in making the right diagnosis of infection, whereas, 63.7% of respondents believed that they were not confident in identifying the clinical scenarios where antibiotics are not required. Significant association (p<0.05) was seen for both “good” knowledge and perception scores with the higher academic semesters reflecting more clinical exposure in later in course semesters. The study has highlighted the areas of clinical weakness and dilemma regarding prescription of antimicrobials. Efforts to address these issues on basic principles of antimicrobial stewardship, is critical for laying the foundation of successful AMS program and contributing in overcoming the antimicrobial resistance. The study recommends targeted training, articulating fine details of prescribing antimicrobials with real time case scenarios through a multi-disciplinary approach. The Indian undergraduate medical curriculum needs to incorporate early well-structured training on AMS by integrating pharmacology and microbiology teaching with the clinical subjects to ensure appropriate antibiotic prescribing practices by the future prescribers.
Deep Neural Network-based Knee Osteoarthritis Grading Using X-Rays
Authors: Wani Zainab Mushtaq , Saini Dr. Satish
Published: May 2022

Abstract: Osteoarthritis (OA) of the knee is a common cause of activity restriction and physical impairment in elderly people. Early identification and treatment can help delay the progression of OA. Physicians' visual examination rating is objective, varies across interpretation, and is heavily reliant on their expertise. We use two machine learning approaches (CNN) in this article to automatically estimate the severity of knee OA as described by the Kallgren- Lawrence (KL) grading system. To begin, we use a customized one-stage YOLOv2 network to recognize kneecap based on the size of knee joints scattered in X-ray pictures with poor contrast. Second, we use a new customizable arbitrary loss to fine-tune its most famous Cnn architectures, spanning ResNet, VGG, and DenseNet versions, as well as InceptionV3, to categorize the collected knee joint pictures. To be more explicit, we provide a stronger penalty to misrepresentation with a greater difference between the predicted and actual KL grade, driven by the ordinal character of the knee KL grading assignment. The Osteoarthritis Institute (OAI) collection is used to evaluate the basic X-ray pictures. Under the Jaccard index criterion of 0.75, we acquire a mean Jaccard index of 0.858 and a recall of 92.2 percent for knee joint identification. The fine-tuned VGG-19 model with the provided linear loss achieves the greatest generalization ability of 96.7 percent and mean standard deviation (MAE) of 0.344 on the knee KL grading task. Both knee joint identification and knee KL assessment are at the cutting edge of technology Keywords: Osteoarthritis (OA), Deep Learning, X-rays, CNN

Abstract: The automated asset tracking system is designed to track lost or lost property in public and elsewhere. As goods are transported by plane or train from one country to another, there is always a risk of theft or negligence of the goods or luggage in which the proposed system is considered. The automatic property tracking system works with an alarm where the alarm is set via the Arduino UNO board and GPS module. Also, the alarm goes off as soon as the bag is misplaced and goes out some distance. In addition, a map is created where we can track the location of the bag as it travels, as the symbols are lowered in a way that gives us the location of the bag as it moves from the desired location. In this way, the components are used as an Arduino board and GPS Module to track cargo and build a front-end or mobile system to monitor lost property. Keywords: Arduino UNO, GPS module

Authors: Cishahayo Laurent , Yang Qian , Zhu Yueji , Wang Fang
Published: May 2022

Chemical packaging waste from pesticides in agricultural lands may cause chronic environmental pollution and health issues if disposed of inappropriately. Using data collected from 632 banana farmers in China through stratified random sampling, we employed the endogenous switching probit model to estimate the relationship between learning behavior and farmers' environmental awareness, and the treatment effect model to examine the association between environmental awareness and farmers' chemical packaging waste disposal behavior. The results show that farmers who participated (vs. did not participate) in self-learning and social learning had greater awareness of environmental protection. Additionally, farmers with greater (vs. less) environmental awareness tended to dispose of chemical waste at appropriate trash sites, underscoring the positive role of environmental awareness in the management of pesticide packaging waste for promoting sustainable agriculture. Implications of the findings are discussed.
Utopijas koordinātes
Authors:   Jāzepa Mediņa Rīgas Mūzikas vidusskola, Nātriņa Iveta
Published: May 2022

The utopia of modern period as a rational construction is characterized by its “inner” architectonics of thought. It was modelled on Plato’s Politeia. For example, both in Thomas More’s Utopia and Francis Bacon’s New Atlantis, the exposition begins with the story told by an experienced sailor about the adventures on a hitherto unknown, distant island. It is depicted as a special place where good virtues prevail, and life has a different, more excellent quality than amongst the society of that time. At the beginning of modernity, these are the so-called utopias of space, which, instead of the future, describe coexisting societies somewhere else on Earth. They have location pointers, although they lack consistently accurate coordinates. T. More’s remarkable innovation – the concept of utopia – includes two original meanings (a place which does not exist and a good place), which refer directly to a place whose coordinates are not known in a geographical sense. The meaning of utopia includes the always present human dissatisfaction with the current quality of existence, thus looking for alternatives – the places worth searching for. One of the most striking phenomena of utopian discourse is the island of Atlantis. The search for its geographical location has gained not only theoretical but also practical manifestations. It is in the discourse of modern period culture that the utopia of space is born as a genre and there is a marked turn towards the active search for various utopian islands, isolated and lost territories. Such a turn is related to significant changes in culture, creating an impulse to discover new worlds, including mythical utopian constructions in the horizon of expectations (R. Koselleck). George Psalmanazar’s false utopia Formosa (the 18th century), which, according to all fake news criteria, exhausts the spectrum of credibility in the discourse of utopia of space, opening up the scene for the utopia of time, is considered to be the sarcastic end of the era of space utopias.
No kalendāru vēstures

Published: May 2022

Since the 7th century BC, Roman calendar consisted of ten months. The year started in March and the first month of the year was called “Martius”, followed by “Aprilis”, etc. In the 6th century BC, two additional months were added to the calendar: the 11th month called “Januarius” and the 12th called “Februarius”. As of mid-1st century BC, the days in the calendar had drifted out of alignment by 80 days. Julius Caesar, the Roman general and statesman, proposed the reformation of the Roman calendar, based on the designs of Greek astronomers, including Sosigenes of Alexandria. In this calendar, today also known as Julian calendar, January was established as the first month of the year, a month in which during that era the statesmen were elected. During the medieval times, the calendars were not compiled for a single year, instead, the calendars were permanent, designed to function for a long period of time. The first permanent calendar to be used in Riga dates back to 1554, and has been compiled by Tarquinius Schellenberg – the physician to Riga archbishop. However, no copy of this calendar has survived. A copy of a subsequent calendar to be used for Riga in 1565, compiled by physician and astronomer Zacharias Stopius, and printed in Koenigsberg has fortunately been still preserved to date. This calendar is titled Schreibcalender auf das Jahr 1565. The Latvian names for the months in the calendar along with the Latin names were included in the calendar for the first time by Paul Einhorn, a historian and Lutheran pastor, in his historical book published in 1649 under the title Historia Lettica. In this book, he referred to winter month “Janvāris”; candle month “Februāris”, etc. The first Latvian calendar bore the title “Peasant or Latvian Time Book” and the titles subsequently of this calendar changed to “New and Old Latvian Time Book”, “Old and New Latvian Time Book” and “Time Book”, printed in Jelgava, Latvia. The wide range of Latvian calendars can be divided into several groups: generic calendars, local calendars (dedicated to certain cities, towns or districts), Latvian calendars published outside Latvia, specialised calendars, such as those dedicated to literature, jurisdiction, music, trade and manufacturing, children, religions, including specific congregations, farming, medicine, crafts, love and women’s activities, sailing, humour and many more, designed to suit the needs of multiple activities and professions.
VITRINES TECNOLÓGICAS: É POSSÍVEL DEMOCRATIZAR A VISIBILIDADE NAS REDES?
Authors: Benicio Milla , Araújo Ana Júlya , Oliveira Gabriel , Viana Júlia
Published: May 2022

O advento e popularização da internet instituiu uma nova lógica de interação, potencialmente mais democrática por abrigar maior pluralidade de vozes. Embora o ecossistema de mídia tenha se transformado, a revolução tecnológica não tem significado emancipação social: existe uma relação de continuidade entre os novos arranjos no campo da comunicação e forças políticas e econômicas já instituídas. Essa desigualdade parece pautar-se principalmente na dinâmica de visibilidade das plataformas digitais, resultante de uma complexa articulação entre fatores sociais, econômicos, políticos e, é claro, técnicos. A navegação personalizada, cuja melhor representação é o feed de notícias do Facebook, faz com que a presença online esteja condicionada a sistemas de classificação e filtragem que tendem a beneficiar “quem fala mais alto”. Tendo isso em vista, o projeto “Vitrines Tecnológicas: uma inovação a favor dos Institutos Federais” foi criado com o objetivo principal de encorajar iniciativas acadêmicas a buscarem visibilidade em ambientes digitais, bem como estimular a divulgação científica. Assim, o trabalho das Vitrines tem sido transformar conhecimento acadêmico em informação acessível, sob diferentes formatos, para um público de leigos ou para determinados nichos fora do universo acadêmico. A parte fundamental deste trabalho é treinar o olhar do docente para a adequação de seus enunciados na web, bem como formar nossos alunos para uma cultura digital.
Building Contrastive Summaries of Subjective Text Via Opinion Ranking
Authors: Rocha da Silva Raphael , Salgueiro Pardo Thiago Alexandre
Published: May 2022

This article investigates methods to automatically compare entities from opinionated text to help users to obtain important information from a large amount of data, a task known as “contrastive opinion summarization”. The task aims at generating contrastive summaries that highlight differences between entities given opinionated text (written about each entity individually) where opinions have been previously identified. These summaries are made by selecting sentences from the input data. The core of the problem is to find out how to choose these more relevant sentences in an appropriate manner. The proposed method uses a heuristic that makesdecisions according to the opinions found in the input text and to traits that a summary is expected to present. The evaluation is made by measuring three characteristics that contrastive summaries are expected to have: representativity (presence of opinions that are frequent in the input), contrastivity (presence of opinions that highlight differences between entities) and diversity (presence of different opinions to avoid redundancy). The novel method is compared to methods previously published and performs significantly better than them according to the measures used. The main contributions of this work are: a comparative analysis of methods of contrastive opinion summarization, the proposal of a systematic way to evaluate summaries, the development of a new method that performs better than others previously known and the creation of a dataset for the task.
Stochastic Models for Planning VLE Moodle Environments based on Containers and Virtual Machines

Published: May 2022

Moodle Virtual Learning Environments (VLEs) represent tools of a pedagogical dimension where the teacher uses various resources to stimulate student learning. Content presented in hypertext, audio or vídeo formats can be adopted as a means to facilitate the learning. These platforms tend to produce high processing rates on servers, large volumes of data on the network and, consequently, degrade performance, increase energy consumption and costs. However, to provide eficiente sharing of computing resources and at the same time minimize financial costs, these VLE platforms typically run on virtualized infrastructures such as Virtual Machines (VM) or containers, which have advantages and disadvantages. Stochastic models, such as stochastic Petri nets (SPNs), can be used in the modeling and evaluation of such environments. Therefore, this work aims to use analytical modeling through SPNs to assess the performance, energy consumption and cost of environments based on containers and VMs. Metrics such as throughput, response time, energy consumption and cost are collected and analyzed. The results revealed that, for example, a cluster with 10 replicas, occupied at their maximum capacity, can generate a 46.54% reduction in energy consumption if containers are used. Additionally, we validate the accuracy of the analytical models by comparing their results with the results obtained in a real infrastructure.
Long-term grazing exclusion increases ecosystem carbon stock but decreases nitrogen stock in the karst alpine grassland of China
Authors: Yang Shimei , Zhang Tao , He Tengbing , Gao Xiaoye , He Yan , Long Tianyu
Published: May 2022

Grazing management practices are a major factor regulating nutrient
cycling and plant growth in grasslands. However, the response of
long-term grazing regimes to ecosystem carbon and nitrogen accumulation
and plant productivity remains uncertain in karst landscapes. A 17
year-long field experiment, constituting the methods of grazing
exclusion (GE), continuous grazing (CG), mowing and grazing (MG), and
rotational grazing (RG), was conducted to assess the effects of
long-term management measures on plant biomass, ecosystem organic
carbon, and nitrogen stocks in a karst alpine grassland of the
Yunnan-Guizhou Plateau. Our results showed that grazing significantly
reduced the aboveground biomass (CG, MG, and RG) and root biomass (MG
and RG) compared to GE, but there were no differences between the
results obtained using the various grazing methods. The root/shoot ratio
increased by 55.98% in CG and decreased by 52.96% and 37.14% in MG
and RG, respectively, compared to that achieved with GE. Soil organic
carbon (SOC) of GE was higher than that of CG, MG, and RG in each soil
layer, while it was significantly higher at 0–10 cm and 20–30 cm.
Grazing promoted the mean total N content with a significant increase in
CG and RG, and significantly increased total P content in each soil
layer compared to GE. Grazing significantly decreased the C/N and C/P
ratios at each soil depth. GE significantly increased the ecosystem
organic carbon stocks (EOCs) and decreased the ecosystem total nitrogen
stocks (ETNs). Although there were no significant changes among the
grazing methods, the EOCs increased by 22.29% (MG) and 16.31% (RG) and
ETNs increased by 7.76% (RG) when compared to those obtained with CG.
EOSs were positively correlated with SOC, stoichiometry (C: N: P), and
aboveground biomass, while being negatively correlated with TP; ETNs
were positively correlated with N and P, while being negatively
correlated with C/N, C/P, aboveground biomass, and root biomass. Our
results indicate that GE can provide significant improvements in plant
recovery and ecosystem organic carbon storage, whereas RG is beneficial
for promoting both EOCs and ETNs under the condition of pasturing
utilisation in karst grasslands.
THE EFFECT OF ORGANIC SOLVENTS ON THE CELL MEMBRANE OF BURKHOLDERIA CEPACIA ZWS15 AND ITS TRANSFORMATION OF CHOLESTEROL: FOCUSING ON CHOLEST-4-ENE-3,6-DIONE AND CHOLEST-4-EN-3-ONE

Microbial transformation of cholesterol produces various steroid drugs
and intermediates, such as cholest-4-en-3-one (C4EO), which is an
important intermediate of hormone steroidal drugs.
Cholest-4-ene-3,6-dione (CEDO) is another product of cholesterol
biotransformation, with better medicinal value than cholest-4-en-3-one.
It is indicated to improve fat metabolism, resistance to tumors and
essential in the treatment of nerve injuries. This study proceeded using
Burkholderia cepacia ZWS15, which is known to produce enzymes to
transform cholesterol. Organic solvents were chosen to increase the
solubility of the substrate cholesterol and the conversion of the
product, and the organic solvent affects the mechanism of product
conversion and cell membrane permeability. The use of organic solvents
in this study prompted shifts in the composition of fatty acids in the
cell membrane, inducing the production of more unsaturated fatty acids
and reduction of saturated fatty acids. The alkenone products generated
after transformation of cholesterol were isolated.

Published: May 2022

Tacheng tick virus 1 (TcTV-1), emerging tick-borne orthonairoviruses,
was firstly isolated from a tick bite patient in northwestern China.
However, TcTV-1 in livestock, wildlife, and potential vectors was still
unknown. From 2017 to 2021, 1495 samples included 180 engorged adult
female ticks, 180 egg batches, 84 larvae, 896 adult ticks, 148 livestock
blood samples, and 7 spleens from red foxes were collected from 14
counties or cities of southern and eastern Kazakhstan, and northwestern
China. The samples were tested for the presence of TcTV-1 using the
viral L segments by reverse transcriptase–polymerase chain reaction
(RT-PCR). The infection rates of TcTV-1 were 7.78% (14/180), 3.89%
(7/180), and 2.47% (2/84) in engorged adult female Hyalommaasiaticum ticks and their offsprings (eggs and larvae),
respectively. 6.45% (9/148) blood samples of livestock and 14.29%
(1/7) spleen samples of red foxes tested positive to TcTV-1. TcTV-1 was
detected in 13.08% (34/260) adult hard ticks from Kazakhstan and 5.35%
(34/636) ticks from China. This findings suggests that i) the pastured
cattle, sheep, camel and wild red fox act as natural reservoirs for
TcTV-1; ii) TcTV-1 is detected in genera of Hyalomma,
Dermacentor, Rhipicephalus and Ixodes both
originated from northwestern China and southeastern Kazakhstan; and iii)
Hy. asiaticum is a potential vector of TcTV-1 due to its
transovarial transmission.

Modern trends in phytochemical extraction from alternative crops support the use of alternative technologies, such as ultrasound- and microwave-assisted extractions. Considering the reduction of toxic solvents, rapid and effective extraction process, the abovementioned technologies have become the foundation of green chemistry approaches in a wide range of applications. These extractions have not been studied on Satureja kitaibelii Wierzb. ex Heuff, which is a highly potent plant when considering its aromatic and medicinal properties. This preliminary study presents an in vitro evaluation of biological activities of ultrasound- and microwave-assisted extracts of S. kitaibelii, for the first time. Furthermore, it offers a totally green, modern, fast and reproducible method for extraction of phytochemicals from S. kitaibelii herba (Rtanj Mountain, Serbia). This short communication suggests that the applied microwave-assisted extraction, using only water as the solvent, can be a promising approach for obtaining green products with commercial potential.

Landscapes of Postmodernity: Donald Barthelme's Architecture
Authors: Sierra Nicole
Published: May 2022

Exploring Donald Barthelme's literary representations of architecture, this essay traces how the author manipulates architectural history as a means of critiquing modernism and contemporary culture. Despite frequent references to Barthelme's familial relationship to architecture, little has been studied about how this intimacy is encoded in his imaginative writings. Focusing on the short story collections Sixty Stories and Forty Stories, this essay considers the usefulness of architecture as an interart analogy for Barthelme's texts. Seizing on the theories of Fredric Jameson, I argue that Barthelme's works highlight popular displeasure with modernist orthodoxy by using strategies similar to early postmodern architecture.

The results of the study indicate that the difficulties faced by history teachers in character education-based learning are difficulties in including the value of the proposition-based character according to the KD, dominant learning is not interactive, and students' character or behavior is difficult to monitor. On the other hand the competence/skills of teachers need to be improved, and the learning designs made by teachers are still weak in supporting character education. Efforts to answer this challenge can be overcome by increasing teacher understanding/mastery of the concept of character education. So it can be concluded that teachers have challenges in integrating character education in students. The implications of this research can have an impact on students in improving their character for the better.
