Production of CO2 Hydrates in Aqueous Mixtures Having (NH4)2SO4 at Different Concentrations; Definition of Consequences on the Process Evolution, Quantification of CO2 Captured and Validation of Hydrates Production as Technique for Ammonium Removal from Waste Water
Authors: Gambelli Alberto Maria , Rushani Xhino , Pezzolla Daniela , Rossi Federico , Gigliotti Giovanni
Published: June 2023

Carbon dioxide hydrates were formed in fresh water and in aqueous mixtures containing ammonium sulfate, at concentrations equal to 1.9, 6.3, and 9.5 wt%. The moles of hydrates formed were compared, to define the inhibiting strength of the electrolyte solution and the dependence of inhibition from concentration. The addition of salt strongly inhibited the process and the number of hydrates produced passed from 0.204–0.256 moles, obtained in fresh water, to 0.108–0.198 moles, obtained at the lowest concentration tested. The further addition of salt still lowered the production of the hydrates; at the highest concentration tested, only 0.092–0.177 moles were obtained. The pressure-temperature evolutions of the hydrates were then discussed and compared with the ideal process and with the experimental results obtained in demineralised water. Finally, further samples of CO2 hydrates, produced in the presence of 9.5 wt% salt in the aqueous phase (corresponding to 1.5 wt% NH4+), were recovered and dissociated in a separated environment. The liquid phase, resulting from their dissociation, was subjected to spectrophotometric analyses. Its NH4+ content was measured and compared with the initial concentration in water. Therefore, it was possible to quantify the capability of the system to remove the (NH4)2SO4 from the water (involved in hydrate formation) and to concentrate it in the remaining liquid phase. Considering the portion of water involved in hydrates formation, the concentration of ammonium passed from 1.5 wt% to 0.38–0.449 wt%.
A Systemic Material Innovation Study of the Current State and Future Possibilities for Circular Polyester
Authors: Hornbuckle Rosie , Goldsworthy Kate , Knight Laura
Published: June 2023

This paper focuses on the current state and future potential of the most prevalent synthetic fibre, polyester, as a circular textile. The aim is to reveal areas for intervention in the current system that might lead the transition to circular polyester in the future. A qualitative Systemic Material Innovation (SMI) study was undertaken to reveal barriers and opportunities to achieving circular polyester from a holistic perspective. Interviews were conducted with 20 industry experts, including co-designing NOW and FUTURE eco-system maps for circular polyester, and a roadmap for transition. Analysis and synthesis of the data revealed that ‘design for reuse and recycling’ is seen as central to realising circular polyester, in particular replacing elastane and ‘fleece’. Inaction by brands, the lack of granular post-use data, appropriate collection practices, and the low-cost of conventional polyester were also highlighted as barriers. Improved understanding of the life cycle impacts and actions amongst all stakeholders was seen as a key opportunity that might be leveraged through dialogue with other stakeholders. Six actions for industry and research are recommended. Data visualisation is used to translate the findings and operationalise the findings for a broad range of stakeholders in the polyester eco-system.

Published: June 2023

The development of sustainable building materials and construction to decrease environmental pollution in both production and operational stages of the materials’ life cycle is appealing to great interest in the construction industries worldwide. This study evaluated the negative effect of temperature up to 1000 °C on the compressive strength and microstructure of fly ash and petroleum sludge ash (PSA) geopolymer mortar. A sodium silicate and sodium hydroxide mixture is used as an activator. The synthesized mortar was investigated using X-ray Diffraction (XRD), Fourier Transformation Infrared Spectroscopy (FTIR), Mercury Intrusion Porosimetry (MIP), and Field Emission Scanning Electron Microscopy (FESEM). As the temperature increased, the compressive strength of the geopolymer mortar decreased. The strength degradation is due to the damage to microstructure because of the temperature-induced dehydroxylation, dehydration thermal incompatibility between geopolymer aggregate and paste of geopolymer mortar at high temperatures. With an increase in temperature, the cumulative pore volume increased. The FESEM image showed the decomposition of the geopolymer matrix started at a temperature of 600 °C. Incorporating PSA in geopolymer mortar could result in an eco-friendly and sustainable environment that may reduce the problems associated with sludge disposal.

Published: June 2023

The emergence of smart cities has addressed many critical challenges associated with conventional urbanization worldwide. However, sustainable traffic management in smart cities has received less attention from researchers due to its complex and heterogeneous nature, which directly affects smart cities’ transportation systems. The study aimed at addressing traffic-related issues in smart cities by focusing on establishing a sustainable framework based on the Internet of Things (IoT) and Intelligent Transportation System (ITS) applications. To sustain the management of traffic in smart cities, which is composed of a hybridized stream of human-driven vehicles (HDV) and connected automated vehicles (CAV), a dual approach was employed by considering traffic as either modeling- and analysis-based, or/and the decision-making issues of previous research works. Moreover, the two techniques utilized real-time traffic data, and collected vehicle and road users’ information using AI sensors and ITS-based devices. These data can be processed and transmitted using machine learning algorithms and cloud computing for traffic management, traffic decision-making policies, and documentation for future use. The proposed framework suggests that deploying such systems in smart cities’ transportation could play a significant role in predicting traffic outcomes, traffic forecasting, traffic decongestion, minimizing road users’ lost hours, suggesting alternative routes, and simplifying urban transportation activities for urban dwellers. Also, the proposed integrated framework adopted can address issues related to pollution in smart cities by promoting public transportation and advocating low-carbon emission zones. By implementing these solutions, smart cities can achieve sustainable traffic management and reduce their carbon footprint, making them livable and environmentally friendly.

Authors: Bai Lifen , Yang Binbin , Yuan Shichong
Published: June 2023

The spread and persistence of the global COVID-19 pandemic has caused online education to gradually become the “new normal” in higher education, and a comprehensive and systematic study of the online course learning of college students in the context of the normalization of online teaching is urgently needed. Higher education is the main stage of cultivating innovative talents, and the evaluation of collaborative education through science and education in the context of online education is also a key content. Therefore, this study established a hierarchical evaluation system based on the Analytic Hierarchy Process (AHP), including three second-level evaluation factors and fifteen third-level evaluation factors. Then, a judgment matrix for each level of evaluation factor was constructed and passed the consistency test. Finally, the weights of each factor were determined, and the feasibility and effectiveness of this method in online learning quality evaluation were verified through a case study. The evaluation results indicate that the cultivation of online learning ability for local college students is more important than online course resources and the online learning environment. In order to promote the realization of educational equity, it is not only necessary to focus on improving students’ academic performance, but also to find ways to enhance students’ learning abilities. In addition, the cultivation of communication and collaboration abilities between teachers and students is an important way to improve the quality of online learning for college students in the process of online learning for college students.
Open Government Data and the Urban–Rural Income Divide in China: An Exploration of Data Inequalities and Their Consequences
Authors: Tan Lu , Pei Jingsong
Published: June 2023

Amidst excitement for the data revolution’s potential benefits, concerns mount over its negative impact as unequal data distribution, access, and use widen disparities between individuals and groups, highlighting the urgent need for advanced theoretical and empirical frameworks. This study investigated the impact of open government data (OGD) on the urban–rural income divide in China. Our theoretical analysis shows that the nonrival nature of data initially widens the urban–rural income divide before eventually mitigating it, resulting in an inverted U-shaped relationship. Using a multiperiod difference-in-differences specification, we found that OGD widened the urban–rural income divide between 2010 and 2019. Furthermore, cities with initially wider urban–rural income divides experienced a greater impact from OGD in expanding this divide. These findings provide valuable insights in the role of open data in addressing income inequality, and contribute to our understanding of data inequalities in the context of the data revolution.
Effects of Support Friction on Mixed-Mode I/II Fracture Behavior of Compacted Clay Using Notched Deep Beam Specimens under Symmetric Fixed Support

Published: June 2023

This paper investigates the effects of support friction on mixed-mode I/II fracture behavior of compacted clay using notched deep beam (NDB) specimens under symmetric fixed support. Numerical models of 330 NDB specimens were established considering the crack inclination angle, crack length, support span, and support friction coefficient, and the normalized fracture parameters (YI, YII, and T*) of NDB specimens were calibrated. The numerical results showed that the values of YI, YII, and T* decreased at different degrees after considering the support friction. Notably, the support friction coefficient could significantly change the loading pattern at the crack tip. To verify this phenomenon, 12 compacted clay NDB specimens were prepared, and a mixed-mode I/II fracture test was performed under fixed support conditions; the phenomenon of asymmetric crack propagation was studied. The test data were processed using the numerical calibration results of YI, YII, and T* with and without consideration of friction. Afterward, the test data were compared and analyzed by combining the generalized maximum tangential stress (GMTS) and the maximum tangential stress (MTS) criteria. The analysis indicated that the real fracture characteristics of compacted clay NDB specimens could not be reflected when conducting mixed-mode I/II fracture tests under symmetric fixed support conditions if the test results were analyzed by YI, YII, and T* without considering support friction, as in previous studies.
Black String Solutions in Rainbow Gravity
Authors: Dárlla Roberta , Brito Francisco A. , Furtado Job
Published: June 2023

In this paper, we studied black string solutions under the consideration of rainbow gravity. We analytically obtained the solution for four-dimensional black strings in terms of the functions f(E/Ep) and g(E/Ep) that sets the energy scale where the rainbow gravity becomes relevant. We also obtained the Hawking temperature for the black string, from which we can see that the rainbow functions play the role of increasing or decreasing the Hawking temperature for a given horizon radius depending on the choice of such rainbow functions. We computed the entropy, specific heat and free energy for the black string. The entropy and specific heat exhibit a rainbow dependence, whereas the free energy is not modified by the rainbow functions. Finally, we studied the effects of rainbow gravity in the orbits of massive and massless particles around a black string. We could verify that neither massive nor massless particles exhibit stable orbits around a black string in the scenario of rainbow gravity for any configuration of rainbow functions.
The Roles of the 5′ and 3′ Untranslated Regions in Human Astrovirus Replication
Authors: Wildi Nicole , Seuberlich Torsten
Published: June 2023

Astroviruses are small nonenveloped single-stranded RNA viruses with a positive sense genome. They are known to cause gastrointestinal disease in a broad spectrum of species. Although astroviruses are distributed worldwide, a gap in knowledge of their biology and disease pathogenesis persists. Many positive-sense single-stranded RNA viruses show conserved and functionally important structures in their 5′ and 3′ untranslated regions (UTRs). However, not much is known about the role of the 5′ and 3′ UTRs in the viral replication of HAstV-1. We analyzed the UTRs of HAstV-1 for secondary RNA structures and mutated them, resulting in partial or total UTR deletion. We used a reverse genetic system to study the production of infectious viral particles and to quantify protein expression in the 5′ and 3′ UTR mutants, and we established an HAstV-1 replicon system containing two reporter cassettes in open reading frames 1a and 2, respectively. Our data show that 3′ UTR deletions almost completely abolished viral protein expression and that 5′ UTR deletions led to a reduction in infectious virus particles in infection experiments. This indicates that the presence of the UTRs is essential for the life cycle of HAstV-1 and opens avenues for further research.

Published: June 2023

In the frame of SARS-CoV-2 infection, studies regarding cytokine profiling of mucosal-related samples are scarce despite being the primary infection sites. The objective of this study was to compare the nasal and fecal inflammatory profiles of elderly individuals living in a nursing home highly affected by COVID-19 (ELD1) with those of elderly individuals living in a nursing home with no cases of SARS-CoV-2 infection (ELD2) and, also, with those of healthy SARS-CoV-2-negative younger adults (YHA). BAFF/TNFSF13B, IL6, IL10 and TNF-α (immunological hallmarks of SARS-CoV-2 infection) were the only immune factors whose concentrations were different in the three groups. Their highest concentrations were achieved in the ELD1 group. Nasal and fecal concentrations of a wide number of pro-inflammatory cytokines were similar in the ELD1 and ELD2 groups but higher than those found in the YHA samples. These results reinforce the hypothesis that immunosenescence and inflammaging rendered the elderly as a highly vulnerable population to a neo-infection, such as COVID-19, which was evidenced during the first pandemic waves.

Published: June 2023

Karst groundwater is the main water source for domestic, industrial, and agricultural needs in Xingtai City, North China. The objective of this study was to comprehensively access changes in the hydrochemical characteristics and evolution of karst groundwater in response to rapid urbanization. Water samples from the late 2010s and the 1970s were compared utilizing statistical analysis, hydrochemical diagrams, and inverse simulation technology. The total dissolved solids (TDS), total hardness (TH), NO3−, and Fe contents were significantly higher in the more recently obtained karst groundwater samples. Further, the dominance of HCO3-Ca-type water decreased, with new types emerging, relative to 1970s karst groundwater. Abnormal TDS, TH, SO42−, NO3−, and Cl− concentrations can be attributed to sewage discharge and fertilizer. Two groundwater discharge areas around the center of Xingtai City and Yangfan Town in the south of the study area were the most significantly affected by human activities. However, inverse modeling indicated that the dissolution of gypsum and halite, as well as cation-exchange processes, occurred in the groundwater paths during both periods. Recent increases in ion concentrations of karst groundwater in the study area have caused carbonate minerals to dissolve, resulting in a further increase of ion concentrations. The hydrochemical response and evolution of karst groundwater requires further study.

Published: June 2023

Studying and understanding the complexity and interactions of different factors influencing stream sediment quality is necessary for the development of successful water quality management strategies. This study aims to evaluate the level of contamination by potentially toxic elements (PTEs) (As, Co, Cr, Cu, Mn, Ni, Pb, V, Zn) of the stream sediments of the Nile River. During the spring of 2019, river sediments were sampled at 23 sites along the Nile River. For each sample, one aliquot was digested in aqua regia and analyzed by ICP-MS for pseudo-total concentration, while for another aliquot, sequential extraction procedures were applied to determine chemical speciation. Compositional data analysis (CoDa) and k-means were applied to recognize the contribution of natural and anthropogenic sources, while pollution indices (EF, RAC) and sediment quality guidelines (SQGs) were applied to assess the ecological risk to biotic species. The results reveal that elements such as Cr, Mn, V and Fe, found in high concentrations in almost all samples (Cr up to 739 mg/kg, Mn up to 1942 mg/kg, V up to 507 mg/kg, Fe up to 98,519 mg/kg), have a natural origin, while the concentrations of Cu (up to 69 mg/kg), Ni (up to 88 mg/kg), Co (up to 42 mg/kg) and As (up to 9.8 mg/kg) are linked to both natural and anthropogenic processes. Sequential extraction shows that Mn, Co, Ni and, in some sites, Cu and Zn, are the most bioavailable elements. These elements present a high risk of toxicity, while the remaining elements imply a low-to-moderate risk.
O mundo, o global e o planetário humanismo de Edward W. Said na era do Antropoceno
Authors: Ribeiro Sanches Manuela
Published: June 2023

Edward W. Said – celebrado ou vilipendiado como um dos “pais fundadores” do campo disciplinar que viria a ser designado de estudos pós-coloniais – sempre recusou rótulos, fiel ao elemento crítico que, segundo ele, deveria assistir a toda a prática intelectual que nunca deveria estar desligada do mundo. A sua (in)tempestividade, patente no modo como esse seu estar-no-mundo não equivalia a um estugar do passo pelas mais recentes modas intelectuais, nomeadamente a sua insistência na leitura de autores heterodoxos, estranhos aos novos cânones descolonizadores, ecoa em particular nos seus últimos escritos, ao mesmo tempo em que se mantém apegado a um humanismo crítico. Como pensar as relações e as disjunções entre o mundo, o global e o planetário (Chakrabarty), considerando a (in)tempestividade do humanismo crítico de Said na era do Antropoceno?
Gerindo identidades marginalizadas entre conhecimento local e cultura global - o ambientalismo como recurso: exemplos da sociedade árabe em Israel
Authors: Sela-Sheffy Rakefet , Stella Marcello
Published: June 2023

A crítica do Orientalismo traz à cena o desempoderamento das culturas locais pela visão ocidental, que, impondo conceitos irrelevantes a um conjunto de contextos, silencia seus meios próprios de vida e sistemas de valores. Contudo, acaba permitindo também um outro tipo de olhar, por uma perspectiva oposta. Ressaltando a criatividade social, suas reações aos repertórios não locais, as culturas locais rejeitam ou incorporam certos elementos para reconstrução de sua própria vitalidade. Tal criatividade social manifesta-se em lutas simbólicas incessantes sobre as identidades locais. Um vetor central dessas lutas é a tensão entre conservação cultural – o uso de uma herança local ou adesão a cânones locais – e a mudança cultural – a adaptação ou ajuste do novo e a transformação das modas. Interligadas na construção da identidade, essas duas dinâmicas se intensificam em situações de tensão étnica e nacional. Neste artigo, portanto, discuto as formas em que as identidades locais são negociadas e transformadas através da valorização ou contestação de repertórios existentes e da intermediação de novos repertórios, como contingentes às lutas de poder dos grupos.

В Республике Беларусь первые эпидемиологические (неинфекционные) регистры появились после аварии на Чернобыльской атомной станции, когда мониторинг здоровья населения стал проводиться повсеместно с целью наиболее раннего выявления особенностей динамики заболеваемости. До 1988 г. в Республике Беларусь не было регистра болезней крови. Белорусский республиканский регистр болезней крови начал создаваться в июле 1988 г. (письмо Министерства здравоохранения Республики Беларусь № 22-3/82дсп от 20.07.1988) в рамках выполнения союзной программы С-27. Регистр содержит персонифицированную информацию о каждом пациенте с гемобластозами начиная с 1979 г. Однако на настоящее время используемая модель формирования базы данных регистра устарела и не отвечает современным требованиям в решении задач, направленных на совершенствование методов диагностики и лечения гематологических пациентов, и не позволяет учитывать материальные и экономические ресурсы, затрачиваемые на лечение каждого пациента. Разработка и внедрение информационно-аналитической системы «Республиканский эпидемиологический регистр пациентов с гематологическими заболеваниями» позволили автоматизировать процесс сбора, накопления, обработки и представления информации по каждому случаю гематологического заболевания, осуществлять планирование оказания специализированной гематологической помощи взрослому населению страны.

First epidemiological (non-infectious) registries appeared in the Republic of Belarus after the accident at the Chernobyl nuclear power plant, when public health monitoring began to be carried out everywhere to identify early characteristics of the incidence dynamics. The registry of blood diseases did not exist in the Republic of Belarus before 1988. The Belarusian republican registry of blood diseases began to be created in July 1988 (letter of the Ministry of Health of the Republic of Belarus No. 22-3/82dsp, July 20, 1988) as a result of the C-27 scientific program. The registry contains personalized information about each patient with hematological malignancies, starting from 1979. However, the currently used model of the registry database does not meet modern requirements for improving the methods of diagnosis and treatment of hematological patients, and does not allow analyzing material and economic resources spent on each patient. Development and implementation of the information and analytical system "Republican epidemiological registry of patients with hematological diseases" made possible automatized collection, accumulation, processing and presentation of information on each case of a hematological pathology, as well as planning of specialized hematological medical care to the adult population of the country.

ВПЛИВ ВКРАЙ ВИСОКИХ ЧАСТОТ НА ПАРОДОНТОПАТОГЕНИ У ХВОРИХ НА ХРОНІЧНИЙ ГЕНЕРАЛІЗОВАНИЙ ПАРОДОНТИТ
Authors: Дєньга О.В. , Пиндус В.Б.
Published: June 2023

Пародонтит – це запальне захворювання, ініційоване специфічними видами бактерій, які колонізують область між поверхнею зуба та краєм ясен. Це захворювання викликає руйнування опорних тканин зуба, включаючи сполучну тканину та альвеолярну кістку, і може призвести до втрати зуба. Мета дослідження. Дослідження присвячене вивченню впливу вкрай високих частот на кількість пародонтопатогенів в зразках пародонтальних кишень пацієнтів з хронічним генералізованим пародонтитом за допомогою методу полімеразної ланцюгової реакції у реальному часі. Матеріали та методи. У дослідженні взяли участь 10 хворих на хронічний генералізований пародонтит початкової, 1 та 2 стадії (середній вік – 47 років). В якості патогенетичної терапії використовували вплив вкрай високих частот. Випромінювач вкрай високих частот прикладався безпосередньо на слизову оболонку ясен у проекції верхівок коренів зубів. Тривалість процедури становила 3-4 хвилини для кожного поля впливу. Наявність та кількість пародонтопатогенів Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Porphyromonas endodontalis, Treponema denticola, Tannerella forsythia, Prevotella intermedia та Fusobacterium nucleatum визначали методом полімеразної ланцюгової реакції у реальному часі. Серед парадонтопатогенів, що вивчалися, найбільшою кількісною присутністю відрізнявся A. actinomycetemcomitans: > 90 % всіх бактерій зразка у 60 % зразків вмісту пародонтальних кишень хворих на генералізований пародонтит. Застосування ВВЧ достовірно знизило кількість P. endodontalis в зразках, що дозволяє рекомендувати ВВЧ в якості одного за методів комплексного лікування хронічного генералізованого пародонтиту.
ОСОБЛИВОСТІ ЛІКУВАННЯ КАНДИДОЗНОГО СТОМАТИТУ НА ТЛІ СОМАТИЧНОЇ ПАТОЛОГІЇ
Authors: Фесенко В.І. , Степанова С.В.

Мета дослідження. Вивчення ефективності лікувального комплексу до складу якого входить CANDIVAC у хворих з проявами кандидозного ураження СОПР з рецидивуючим перебігом на тлі хронічного вірусного гепатиту В в фазі реплікації. Методи дослідження. Cпостереженню підлягали хворі на хронічний вірусний гепатит В (ХВГВ) в фазі реплікації, у яких було діагностовано мікроскопічно та лабораторно 4 випадки кандидозного стоматиту впродовж останніх 12 місяців. Встановлення діагнозу рецидивуючого перебігу кандидозного стоматиту обґрунтовували на підставі клінічних проявів, шляхом мікроскопічного та бактеріологічного дослідження патологічного матеріалу з вогнища ураження. Контроль ефективності терапії проводилось безпосередньо перед призначенням CANDIVAC в складі комплексної терапії та через 21 днів після початку лікування, а також повторювався у віддалені строки 9 та 12 місяців. Наукова новизна. Динаміка суб’єктивних скарг та мікробіологічного дослідження показала позитивні зміни в перебігу лікування, а саме: уже через 21 день лікування у 64 % обстежених відзначалось зникнення симптомів захворювання, а також спостерігалась відсутність збудника інфекції в мазках зі СО рота та в кишечнику. Звертає увагу той факт, що у осіб з ХВГВ в яких фаза реплікації продовжувалась не більше 2 років реєструвався більш ефективний вплив лікувального комплексу. Аналіз ефективності диспансеризації через 9 та 12 місяців після введення CANDIVAC показав значне покращення в оцінці суб’єктивних скарг та мікробіологічних показників. В той час у пацієнтів ХВГВ фаза реплікації у яких була тривалістю більше 5 років зниження обсіменіння слизової рота та кишечника було менш ефективне. Висновки.

Stability of the implants is based on its endurance, which is very important for further decision and prognosis. For creation of hydrophilic surface were instilled the different methods of treatment. At the same time, the efficiency of photoactivation method and its perspectives for the increasing of the implant stability is not yet enough researched and needs the special attention. The aim of the study is to assess the stability of two groups of implants, evaluated either by the grit blasting processing and acid etching alone, or with additional photoactivation, using resonance frequency analysis (RFA). 101 implants of 56 patients (20 men and 36 women) were studied, 53 of them were treated with grit blasting processing and acid etching, and 48 with photo activation. The Implant stability quality (ISQ) was measured using the RFA method on the day of the implant set, and after 2, 8 and 16 weeks for each implant. For statistical analysis was used software package Statistica 10.0 for Windows, with following calculating M (arithmetic mean) and m (error of the arithmetic mean). Differences at p<0.05 were signed considered probable. After 8 weeks, higher indices of the stability of the implant were established in the group where photoactivation was applied (for 4,1 points ISQ, p<0,05). After 16 weeks, the implant stability quality factor was likely to be higher after the photoactivated surface of the implant (3,9 points ISQ, p<0,05). When comparing the stability ratio of the upper-jaw and lower-jaw implants in each group, both groups showed a higher coefficient of stability of the implant for the lower jaw than for the upper-jaw implants at each stage of observation (p<0,05). The average ISQ value was higher in implants with super hydrophilic surface, treated with a photocatalytic effect than in those, who did not receive such treatment, i.e. photoactivation of the surface of the implant promotes osteointegration by increasing the hydrophilic surface. Keywords: implant's stability, implant stability quality, photoactivation, resonance-frequency analysis.

A thorough investigation of the underlying immunopathogenetic pathways is required in order to create effective therapeutic methods for the complex clinical cases of patients with an autoreactive immune system that can harm the organism. Currently, the most commonly used therapeutic alternatives have severe side effects and reduced effectiveness after long-term treatment of patients with autoimmune diseases. The secretome of mesenchymal stem cells (MSCs-secretome) does, however, contain compounds with potential therapeutic applications, a promising new clinical strategy for treating the aforementioned patients. The data presented in this review summarizes information from experimental research and a small amount of clinical practice knowledge. It also raises fundamental questions regarding the role of modern, innovative therapies in helping autoimmune patients.

Pigs are meat-producing livestock that are widely raised in the community, as one of animal protein source for the human body. Pork can be processed into various kind of food, one of which is pork jerky. Jerky can be made using sliced ​​or ground pork. Jerky can be dried traditionaly (sun dried) or more advanced way (oven dried). The purpose of this study was to determine the effect of different drying methods on the organoleptic quality of pork jerky. The results based on paired t-test analysis showed that there was no significant difference (P>0,05) between the smell, texture and acceptability of pork jerky with different drying treatments. Meanwhile, the analysis of the color and taste of pork jerky showed a significant difference (P<0,05) between the two treatments. Although statistically there are differences between two drying treatments, the average number show a very small the differences. In conclusion, both oven-dried and sun-dried pork jerky are acceptable and suitable for consumption.
Transparencia y participación ciudadana: del dicho al hecho
Authors:   , Furnari Diego Martín
Published: June 2023

La presente investigación se desarrolla en el marco del Doctorado en Comunicación de la Universidad Nacional de La Plata. La misma busca analizar las estrategias de transparencia y participación ciudadana en las áreas de presupuesto participativo y seguridad ciudadana, y sistematizar los rasgos característicos de las estrategias de comunicación (tanto en lo relativo a la comunicación gubernamental como a la electoral) desplegadas en los municipios de Berisso, La Plata y Avellaneda; y, por otro lado, comparar tales rasgos entre el período 2011-2015 y el período 2015-2019. Se propone reflexionar, a partir del análisis de un corpus de información vinculado a los conceptos transparencia y participación ciudadana, respecto del rol los mismos ocupan como estrategias discursivas y políticas en ciertos contextos territoriales. Dada la multiplicación que este tipo de propuestas, acciones y transformaciones tuvieron y tienen en muchos de los Estados actuales, se vuelve indispensable profundizar y diversificar los análisis al respecto. Se parte del supuesto según el cual esas iniciativas responden, en primer lugar, a la existencia de una necesidad de legitimación por parte de los gobiernos o alianzas electorales y, por el otro, a una demanda social en virtud de cierto hartazgo de los modos de relacionamiento tradicionales entre gobernantes y gobernados.

El artículo parte de la necesidad de sistematizar los estudios sobre el ciberacoso a jóvenes y adolescentes a través de las redes sociales. El alcance de la investigación es exploratorio y el objetivo fue realizar una revisión de literatura para determinar las principales tendencias que sobre este hecho social y delictivo. La metodología se organizó por estrategia de búsqueda en las bases de datos Redalyc, Latindex, DOAJ y ERIH PLUS, con un cierre temporal de 15 años (2007-2022). La muestra analizada fue de 25 papers bajo los criterios de inclusión establecidos. Las categorías establecidas fueron: acoso en redes sociales; contenido pornográfico no consensuado, sexting, grooming o training; y, discursos de odio. Los resultados evidencian un incremento de estas prácticas en los últimos años como consecuencia de la proliferación del tiempo dedicado a internet por los jóvenes y adolescentes, el avance de las tecnologías de la información y las comunicaciones (TICs) y el refinamiento de las prácticas delictivas para burlar controles. Sobre todo, ello tiene alta repercusión en poblaciones de jóvenes y adolescentes vulnerables.

La Fundación Juan March (Madrid, 1955) institucionalizó un importante programa de mecenazgo que incluía becas para estudios en el extranjero en distintas áreas. Dentro de las ayudas dedicadas a música, entre 1962 y 1966 se concedieron seis para la realización de cursos sobre el método Orff en Salzburgo. Este trabajo pretende aproximarse al papel de la Fundación en la recepción del Orff-Schulwerk en el territorio español, además de esclarecer la filosofía, contenido y estructura de las acciones formativas desarrolladas. La principal fuente empleada han sido las memorias de prácticas generadas por los beneficiarios tras sus estancias. El análisis revela el papel pionero de la institución en la introducción de esta propuesta pedagógica renovadora en la España franquista, matizando ideas previas al respecto. La posterior propagación del Orff-Schulwerk en España supondrá un giro radical en la educación musical básica en consonancia con los postulados liberales de la nueva Ley.

Pademi covid-19 telah mengganggu proses pembelajaran secara konvensional. Maka diperlukan solusi untuk menjawab permasalahan tersebut. Pembelajaran secara daring adalah salah satu alternatif yang dapat mengatasi masalah tersebut. Tujuan penelitian adalah untuk memperoleh gambaran pelaksanaan pembelajaran daring di Sekolah Dasar Islam Majlis Tafsir Al-Qur’an Karawang sebagai upaya menekan penyebaran covid-19 di Sekolah Dasar. Subjek penelitian adalah siswa sekolah dasar kelas 6. Data dikumpulkan dengan wawancara melalui zoom cloud meeting. Analisis data dilakukan menggunakan teknik analisis interaktif Miles & Huberman. Hasil penelitian menunjukkan bahwa: (1) Siswa telah memiliki fasilitas-fasilitas dasar yang dibutuhkan untuk mengikuti pembelajaran daring; (2) pembelajaran daring memiliki fleksibilitas dalam pelaksanaannya dan mampu mendorong munculnya kemandirian belajar dan motivasi untuk lebih aktif dalam belajar; dan pembelajaran jarak jauh mendorong munculnya perilaku social distancing dan meminimalisir munculnya keramaian siswa sehingga dianggap dapat mengurangi potensi penyebaran Covid-19 di lingkungan sekolah dasar. Lemahnya pengawasan terhadap siswa, kurang kuatnya sinyal di daerah pelosok, dan mahalnya biaya kuota adalah tantangan tersendiri dalam pembelajaran daring. Meningkatkan kemandirian belajar, minat dan motivasi, keberanian mengemukakan gagasan dan pertanyaan adalah keutungan lain dari pembelajaran daring.
