A Study of The Characterization of Purified Fly Ash from Xi’an Linyuan Silica Limited
Authors: Kamara Saidu , Foday Jr Edward Hingha , Wang Wei
Published: July 2023

Coal is a well-known source of electric power generation all over the globe. Pulverized coal combustion and fluidized coal bed combustion are the two conventional methods involved in the combustion of coal in thermal power plants. Pulverized coal combustion is operated at >14000C while the fluid bed is operated at a temperature between 850-9000C. The first two reactions are the main reactions in the coal combustion process and they are exothermic reactions. CO2 and CO are the first two combustion products. The inorganic minerals in coal are released as waste products in the combustion plants in which fly ash made a large part of the waste materials. Fly ash is formed due to the incomplete combustion of coal. The fly ash from both methods contains SiO2, Al, etc, which are significant constituents. High-grade coal has a higher SiO2 than the low grade. An experiment was conducted by preparing four samples of fly ash heated at 5000C, 6000C, 7000C, and 8000C, and one unheated sample to investigate the chemical composition of the fly ash obtained from Xi’an Linyuan Silica Limited and to prove its suitability as raw material for the fabrication of refractory composites. SEM, EDS, XRD, and FTIR characterization were done on all five samples to determine the chemical parameters of the fly ash. According to the result and analysis of the four characterizations, it was discovered that the fly ash used in this research contains SiO2. SEM/EDS morphological analysis reveals the presence of spherical and a few geometrical crystalline-shaped structures known as cenospheres. Cenospheres are important components for the synthesis of refractory composites. The EDS micrographs show the percentages of silicon and oxygen in the fly ash. The FTIR results show Si-O-Si stretching in all the fly ash prepared samples. In the XRD, it was discovered that the fly ash was purely SiO2.

U težnji da se poveća produktivnost rada, smanje troškovi proizvodnje i humanizira rad, proizvodnja u oblasti iskorišćavanja šuma pretrpjela je u posljednje vrijeme znatne tehnološko-organizacione promjene koje su direktno uslovljene uvodjenjem savremenih mehanizovanih sredstava za rad u tehnološki proces proizvodnje. Mašinski rad, u poredjenju s manuelnim, neuporedivo je lakši, produktivniji i jeftiniji, ali pod uslovom da se ugradjeni mašinski kapaciteti iskoriste na odgovarajući način. Nedovoljno iskorišćavan je mašinskih kapaciteta dovodi do naglog povećanja jediničnih troškova i dovodi u pitanje ekonomičnost proizvodnje. Da bi se ugradjeni kapaciteti mašina dovoljno i rentabilno iskoristili, potrebno je obezbijediti kontinuirani rad mašina i bez znatnijih vremenskih gubiataka, što, s obzirom na specifičnosti proizvodnje u iskorišćavanju šuma (nehomogenost objekta rada, varijabilnost uslova rada, raštrkanost predmeta rada na relativno velikoj površini i dr.), nije ni lako ni jednostavno postići. Stoga se problem šumske mehanizacije kao najznačajnijeg faktora racionalizacije rada svodi na pitanje načina njene primjene i stepena iskorišćenja.

Da bismo došli do odgovarajućih saznanja potrebni su nam dugoročni, planski i sistematski postavljeni i vodjeni ogledi s vrstama koje karakteriše brz rast i dobar kvalitet drveta, u različitim stanišnim uslovima i omjerima smjese. Jedna od vrsta drveća u kojoj su sjedinjene navedene odlike jeste evropski ariš (Larix decidua Mili.). Medjutim, evropski ariš ima veoma širok prirodni areal vrlo raznolikih ekoloških uslova, a posebno klimatskih. U takvim uslovima izdiferenciralo se mnogo rasa (populacija) i ekotipova. Da bi se provjerile proizvodne mogućnosti te vrlo važne ekonomske vrste u našim uslovima, prof. Pintarić je u sklopu internacionalnog ogleda evropskog ariša,kojim rukovodi prof. Schober , postavio 1961. godine jedan dugoročni ogled sa raznim provenijencijama evropskog ariša u Rakovici (Batalovo brdo) kod Sarajeva. Ogled se nalazi u pojasu montane bukove šume na nadmorskoj visini 635 m, na mjestu gdje je posječena bukova "niska" šuma.

U uslovima robno-novčane privrede potreba za ostvarivanjem e- nomskih principa u poslovanju privrednih organizacija u šumarstvu sve više dolazi do izražaja s ciljem ekonomske stabilizacije ove važne privredne oblasti i, u vezi s tim, što potpunijeg obavljanja njene funkcije u okviru proširene društvene reprodukcije. Medjutim, odgovarajućom analizom dolazi se do saznanja da je akumulativna i reproduktivna sposobnost šumarstva još uvijek nedovoljna za vodjenje proširene reprodukcije i , da u tom pogledu šumarstvo znatno zaostaje za drugim privrednim oblastima. Zato je ta problematika aktuelna i veoma značajna za radne kolektive.Mogućnosti za njihovo djelovanje su široke ali su u tom otvorena mnoga pitanja s obzirom na prirodu reprodukcije u šumarstvu i nedovoljnu istraženost njene ekonomske komponente.

U toj ekonomskoj problematici šumarstva svakako značajno mjesto zauzima kompleks pitanja iz područja investicija, a medju njima posebno pitanje pravilnog njihovog usmjeravanja.Imajući to u vidu obradili smo ovaj zadatak sa željom da razjašnjenju tog pitanja damo svoj doprinos.

Published: July 2023

We explored the annual risks of mild and severe preeclampsia (PE) among nulliparous women. Using the National Health Information Database of South Korea, 1,317,944 nulliparous women who gave live births were identified. Mild PE increased from 0.9% in 2010 to 1.4% in 2019 (P for trend=0.006), while severe PE decreased from 0.4% in 2010 to 0.3% in 2019 (P=0.049). The incidence of all types of PE (mild and severe) showed no linear change (P=0.514). Adjusted odds ratio (OR) of severe PE decreased in 2013 (0.68; 95% confidence interval [CI]: 0.60, 0.77) and beyond compared to that in 2010, while the OR of mild PE increased in 2017 (1.14; 95% CI: 1.06, 1.22) and beyond. Mild PE was found to be less likely to progress to the severe form since 2010; however, the overall risk of PE among women did not change.

La educación inclusiva ha marcado como estándar de calidad la atención a las personas con diferencias. Toda persona es diferente en alguna de las siguientes dimensiones: cognitiva, psicológica, físicomotora o sociocultural. La práctica actual a nivel internacional insta a las instituciones educativas a considerar en su operatividad los siguientes principios de la inclusión: (a) acceso de toda persona a todo lugar (independientemente de sus diferencias), (b) actitud de colaboración al trabajar con personas diferentes, (c) intervención temprana para obtener mejores resultados, (d) capacitación para la intervención con personas con diferencias y (e) adecuación de contenidos, equipos e infraestructura para la atención a personas con diferencias. El diagnóstico de los lineamientos de inclusión es una de las estrategias que permiten, tanto a la institución como al personal educativo y a las familias, identificar fortalezas y áreas de posibilidad en el crecimiento hacia el nivel ideal de inclusión. Este trabajo presenta el diseño y las características técnicas de un instrumento que ayuda a las instituciones educativas en dicho diagnóstico. Para el diseño y validación del instrumento se siguieron varias etapas, desde el fundamento teórico, pasando por la elaboración de los reactivos, su validez de contenido a través de 10 expertos, su validez de constructo con un Análisis Factorial Exploratorio y Confirmatorio. El resultado final es un modelo de Inclusión Educativa con cuatro ámbitos compuesto por 21 reactivos y que explican un 73.3% de la varianza. Esta estructura factorial mostró un ajuste bueno, estabilidad buena con adecuada confiabilidad, validez convergente y validez discriminante.

Published: July 2023

En el campo de la educación, el aprendizaje colaborativo, el learning-by-doing y la evaluación entre pares se han convertido en estrategias pedagógicas ampliamente reconocidas y utilizadas. Estas estrategias, cuando se aplican adecuadamente, pueden brindar numerosos beneficios al estudiantado. El objetivo final de este artículo se centra en examinar la efectividad de la evaluación entre pares y del aprendizaje colaborativo en un contexto con metodología learning-by-doing en la materia “Gestión de las Organizaciones” del Grado de Inteligencia Artificial de la Universidade da Coruña. Asimismo, se busca observar cómo esto puede contribuir al empoderamiento del alumnado en su propio proceso de aprendizaje. Con ese fin, se desarrolló una actividad que implicaba la formación de equipos para crear un plan de empresa. De esta manera, el estudiantado tuvo la oportunidad de aplicar de manera concreta los conocimientos sobre matemáticas financieras y gestión empresarial adquiridos en la materia. A la luz de los resultados obtenidos, se puede afirmar que el alumnado valoró la actividad, en general, de manera positiva. Además, se ha observado una diferencia significativa entre mujeres y hombres en cuanto a la percepción de utilidad de la actividad y aprovechamiento para su futuro profesional, con una percepción más favorable por parte de las mujeres. También es destacable que el estudiantado se sintió motivado con la experiencia y la gran mayoría superó la materia. En definitiva, al combinar estas estrategias, se generó un entorno de aprendizaje dinámico en el cual el alumnado participó activamente en actividades prácticas y desempeñó un papel activo en la evaluación y retroalimentación del trabajo de sus compañeros y compañeras. Esta sinergia promueve un aprendizaje más profundo, colaborativo y autónomo, ya que el alumnado no solo adquiere conocimientos, sino que también desarrollan habilidades críticas de análisis, comunicación y trabajo en equipo.

Published: July 2023

El desarrollo de la competencia motriz en la primera infancia y el trabajo de psicomotricidad se ha convertido en el eje principal del desarrollo humano. Este estudio tiene como principal objetivo conocer la opinión del profesorado que imparte la sesión de psicomotricidad en centros educativos de Educación Infantil. Se indaga sobre qué entienden por psicomotricidad, cómo perciben la competencia motriz de los niños y cómo gestionan la clase de psicomotricidad. Para ello se ha realizado una entrevista semiestructurada a un total de 9 docentes de Educación Infantil de diferentes centros educativos distribuidos por España. Los resultados indican que los maestros y maestras relacionan la psicomotricidad con el movimiento corporal y la mente. A su vez, en la puesta en práctica de sus sesiones le dan prioridad al trabajo de ciertos componentes de la psicomotricidad (esquema corporal, estructuración espacial y aprendizaje globalizado) frente a otros (equilibrio, control postural o lateralidad). Hay que comentar que ante cualquier conflicto surgido entre el alumnado la mayoría opta por establecer un puente de mediación. Con relación a la competencia motriz de los niños percibida por los docentes, estos afirman que ha empeorado con el paso de los años y que el juego en la calle ha desaparecido. Se concluye la necesidad de aumentar el número de horas de psicomotricidad en los centros educativos, tanto a nivel escolar como extraescolar y la formación específica sobre este ámbito en el profesorado que la imparte a fin de mejorar la competencia motriz de los niños y niñas.

Published: July 2023

Universities are a context where actions are being taken to develop sustainable skills that will allow the achievement of the SDGs, with sustainability being incorporated into campus management and curriculum. Consequently, this study analyzes the level of SDG knowledge and perception of future early childhood education and primary school teachers. The aim is to give visibility to the impact of university curricula on their training. A quantitative methodology is chosen that uses a questionnaire which collects both sociodemographic information and other information specifically linked to the SDGs (knowledge level, training contexts and the need to incorporate the SDGs into the study plans of the degrees). The analysis of the results has been carried out using the Excel program. The most notable results are the lack of training and knowledge in terms of SDGs, as well as doubts regarding the incorporation of the SDGs into the undergraduate curriculum. For this reason, it is concluded that current education curricula are not meeting their objectives of promoting knowledge and practical application of the SDGs in future teachers. Consequently, it is necessary to revise the curricula so that they promote sustainability from theory and practice, promote training in teaching about the SDGs among university professors and promote spaces among future teachers where good SDG practices in compulsory education are shared.

En los niveles educativos preescolar y básica primaria no hay docentes Licenciados en educación física como expone en la carta internacional de la Unesco y el Ministerio de Educación Nacional. En la presente investigación se indagarán las estrategias que usan los docentes rurales para el área de la educación física, ya que son docentes de otras áreas del conocimiento. Se usó el paradigma naturalista, con un enfoque cualitativo cuyo método fue el etnográfico, por medio de técnicas de recolección e instrumentos pertinentes y una técnica de análisis de datos a necesidad. Los resultados dictan que los docentes solicitan que esta asignación académica se le sea dada al profesional encargado para llevar a cabo el proceso educativo desde las necesidades del área. En conclusión, el licenciado en educación física también debe estar en los niveles de formación del preescolar y básica primaria que apoye la transversalización solicitada por la comunidad.

Eğri Disk Kararsızlığı: Analitik Öngörüler ve Nümerik Simülasyonlar
Authors: DOĞAN Suzan
Published: July 2023

Hem kuramsal modeller hem de gözlemsel bulgular astrofiziksel toplanma disklerinin genellikle eğri bir yapı sergilediğine işaret etmektedir. Eğri disk dinamiğine ilişkin analitik incelememize göre, kritik eğrilik değerine ulaşan diskler kararlılığını koruyamaz. Yoğunluğun ve eğriliğin anti-difüzyonu formunda beliren kararsızlık, diskin halkalara ayrılmasına neden olur. Bu çalışmada, kararsızlık analizinden elde ettiğimiz analitik öngörüleri test etmek amacıyla, dönen bir kara delik etrafında Lense - Thirring etkisi nedeniyle presesyon yapan disklerin kararlılığına ilişkin yüksek çözünürlüklü ve 3-boyutlu hidrodinamik simülasyonlar yapıldı. Diskin açısal momentum vektörü ile kara deliğin spin vektörü arasındaki açı (eğiklik), kalınlık ve viskozitenin eğri disk evrimi üzerindeki etkileri araştırıldı. Simülasyon sonuçlarına göre, (i) eğikliği büyük olan diskler kararsız kalmaya daha eğilimlidir; (ii) viskozitesi düşük diskler daha küçük eğrilik değerlerinde kararsız kalmaktadır; (iii) kalınlık, eğri disk evriminde belirleyici rol üstlenmektedir. Bu sonuçlar, kararsızlık analizinden türettiğimiz analitik öngörüleri doğrulamaktadır. Disklerde parçalanma süreci, toplanma oranlarını dramatik bir biçimde değiştiren ve X-ışın çiftleri ile Etkin Gökada Özeklerinde kısa zaman ölçeklerinde gözlenebilir özellikleri açıklama potansiyeli taşıyan bir süreç olarak karşımıza çıkmaktadır.

Authors: Inga Macancela Ana Paulina
Published: July 2023

Introducción: El primer estudio retrospectivo realizado en el lugar donde inició la pandemia COVID-19 no reporta manifestaciones cutáneas en los pacientes. Posterior hubo un reporte de 0,2% luego 4,9% y 20,4% de afecciones dermatológicas presentes en contagiados por la enfermedad, sin embargo, siempre se consideraban inespecíficas e inusuales, por lo que es notorio que no se estudió la dermatología en pacientes contagiados. Objetivo: analizar las manifestaciones cutáneas que se presentan en pacientes infectados por COVID-19 mediante una revisión sistemática Métodos: esta investigación detalla las manifestaciones cutáneas de los primeros estudios realizados desde el año 2020 mediante la selección por criterios de inclusión y exclusión. Resultados: dependen de varios factores y es posible encontrar lesiones tipo pseudo-sabañones, lesiones vasculo-purpúricas, urticaria, rash, maculopapular, lesiones acrales con eritema, livedo y necrosis, no obstante, existe un factor clave y es que muchas veces se podía confundir las manifestaciones cutáneas con las reacciones adversas provocados por medicamentos utilizados para combatir la enfermedad. Pese a los resultados obtenidos en esta revisión, en los niños no se puede definir los mismos determinantes ya que en ellos no se reportan dichas manifestaciones que ofrezcan datos de importancia, solo existen reportes de eccemas maculopapular eritematosos, no pruriginosos en cuello y tronco, urticaria. Conclusiones: al tener un primer contacto con un paciente contagiado por COVID-19 se debe realizar un abordaje completo e integral del paciente ya que existen numerosas manifestaciones que orientan al diagnóstico y no se debe pasar inadvertido la dermatología en un paciente infectado.

This study aims to evaluate the effects of service quality, security, and price perception on consumer trust and purchasing decisions on Tokopedia. Additionally, this study also aims to examine the mediating role of consumer trust in the relationship between the variables of service quality, security, price perception, and purchase decisions. The research was conducted in Yogyakarta using the snowball sampling method to select a sample of Tokopedia customers. A total of 250 respondents participated in the study. Data collection was carried out through questionnaires using a Likert scale of 1-5. Data analysis was performed using the Partial Least Squares (PLS) method with Smart PLS 3.3.3 software. The results showed that the security variable and price perception significantly influenced consumer trust, while service quality had a significant negative relationship with purchasing decisions. However, the variables of service quality, security, and price perception did not have a significant influence on purchasing decisions. Consumer trust was found to mediate the effects of security and price perception on purchasing decisions, but it was unable to mediate the effect of service quality. Overall, Tokopedia needs to improve communication regarding service quality, ensure a high level of security, consider other factors that influence purchasing decisions, and continue to build consumer trust.

TRIMETHOPRIM-SULFAMETHOXAZOLE FOR PNEUMOCYSTIS JIROVECII PNEUMONIA PROPHYLAXIS AMONG HIV-POSITIVE PATIENTS IN THE ERA OF EARLY ANTIRETROVIRAL THERAPY INITIATION

Published: July 2023

Background: Trimethoprim-Sulfamethoxazole (TMP-SMX) is currently recommended for the primary prevention of Pneumocystis jirovecii pneumonia (PCP) among HIV-positive patients whose CD4 count is less than 200 cells/mm3. However, adverse drug reactions (ADR) have been reported among some patients. In the era of early antiretroviral therapy (ART) initiation, the prevalence of PCP has gradually decreased. Therefore, to avoid unnecessary ADR, TMP-SMX might be less beneficial when the patient receives early ART initiation.

Objectives: The study aimed to evaluate the incidence of PCP, all-cause mortality, CD4 count at 6 months after ART, other opportunistic infections (OIs), and ADRs among HIV-positive patients receiving early ART initiation with and without TMP-SMX for PCP prophylaxis.

Methods: This retrospective cohort study was conducted in Ratchaburi Hospital between January 2014 and February 2022. HIV-positive patients with an initial CD4 count <200 cells/mm3 or <14% and receiving early ART initiation within 2 weeks after HIV diagnosis were investigated. Patients with and without TMP-SMX prophylaxis were analyzed in terms of baseline characteristics, the incidence of PCP, all-cause mortality, other OIs and ADRs from TMP-SMX. The ratio of TMP-SMX vs. no TMP-SMX groups was 2:1.

Results: In total, 230 HIV-positive patients presenting an initial CD4 count <200 cells/mm3 or <14% were included in this study. All patients received early ART initiation within 2 weeks after HIV diagnosis and showed good adherence. The incidence of PCP in the TMP-SMX prophylaxis group was 2 of 153 cases (1.31%) and in the no prophylaxis group was 3 of 77 cases (3.89%), OR 0.329; 95% CI, (0.053 – 1.998); p=0.226. CD4 count at 6 months after ART initiation significantly increased in the no prophylaxis group (277.4 vs. 179.5 cells/mm3; mean difference 97.92; 95% CI of difference, (65.15-130.69); p <0.001). All-cause mortality and other bacterial and OIs did not differ between the two groups. All adverse events from TMP-SMX were minor rashes, 13 of 153 cases (8.5%).

Conclusion: Among HIV-positive patients receiving early ART initiation, the incidence of PCP revealed no difference between with and without TMP-SMX prophylaxis. All-cause mortality and rate of OI were also comparable between the 2 groups.
