Study on circulating characteristics of circulating fluidized bed
Authors: Yu Sijin , Liu Shaobei
Published: February 2024

Based on the Euler-Euler two-fluid model, the circulating fluidized bed was simulated using the computational fluid dynamics (CFD) method. The physical model of the circulating turbulent fluidized bed had an inner diameter of 76mm and a height of 2000mm. The circulating material consisted of class B particles, with an initial bed material mass (Mp) of 0.188kg. Air was uniformly introduced at a velocity of 0.3m/s at the bottom of the riser, and secondary air was introduced at a velocity of 0.9m/s at the secondary air inlet. Numerical simulations were conducted to study the gas-solid flow characteristics of the entire circuit. The turbulent bed, fast bed particle concentration, material circulation rate, and pressure drop gradient were analyzed to evaluate the performance of the entire circuit. The results showed that the particle concentration at the bottom of the riser was higher in the overall circuit flow, and a turbulent state could be achieved at low gas velocities. The particle concentration in the transport bed was low, indicating good gas-solid interaction. Strong backmixing occurred at the connection between the return valve and the turbulent bed. Additionally, there was intense gas-solid reaction at the secondary air inlet.

Published: February 2024

Perfect cleaning and shaping is the key to successful root canal treatment. Therefore, a careful understanding of the internal anatomy and structure of the root canal system is an important factor when performing cleaning and cosmetic procedures. Mandibular premolars are among the most complicated teeth to treat with root canals due to their abnormal root canal anatomy. Furthermore, it varies in different ethnic groups. Therefore, it is needed to evaluate and search for an abnormal root canal anatomy in a failed root canal. In light of these observations, this case report provides a case of previously root canal treated mandibular first premolar tooth which was failed due to different root canal patterns. The tooth was subjected to re-root canal treatment and after completion of the therapy, the tooth was symptomless and patient was referred to the Department of Prosthodontics for a full veneer crown.

Authors: Ladia Jade Brylle T.
Published: February 2024

The alarming rise of COVID – 19 positive cases forced the Philippines to suspend the teaching and learning process in the traditional face-to-face delivery modality. It is very evident that the rapid change in learning delivery mode significantly increase academic demand and workload. In the study conducted by Talidong & Toquero (2020), Negative effects of the above-mentioned challenges manifest on how educators and parents, as well as learners, fully embrace the new landscape of education. Hence, the purpose of this research was to explore the perception of the parents on the implementation of distance learning at BPES that served as a basis to improve its implementation on the coming academic year. The present study employ the quantitative research model anchored on the survey-model. The results obtained from the online survey for each areas of concern (1) that parents struggled adjusting to online learning environment, (2) parents agree (x̄ = 3.59) that they are adjusting to changing study environment, (3) parents partially agree (x̄ = 2.89) that their children were unable to interact with teachers and (4) parents partially agree (x̄ = 3.12) that teachers give unclear instructions.These results present the following opportunities for BPES as it continues to provide quality education despite the pandemic.
An Efficient Ontology Based Machine Learning for Classifying High Definition Satellite Images (Chandrayaan-3)
Authors: Karahari Chandrakanth Rathod
Published: February 2024

The analysis of satellite images to determine the kind of land, forest cover, plant type, and other aspects of a particular image has become a standard practice. Object-based image classification for land-cover mapping with remote-sensing data has received a lot of interest in recent years. Several researches have looked into a range of sensors, feature extraction, classifiers, and other important elements throughout the last decade. These data, however, have yet to be gathered into a complete reference on the implications of different guided object-based land-cover categorization methods. To solve this issue, we provide an ontology-based conceptual UKNN classification algorithm in this study. We create an 18-field database from the rit18 database's qualitative and quantitative data in this research. Instead of unexplainable characteristics provided by a CNN, this proposed study uses an ontology-based methodology framework to enable picture classification using features extracted from hyper spectral image data. The image is initially given a Gaussian filter. The suggested UNet K nearest neighbours (UKNN) classifier is utilised to translate the ontology components into image-based parameters, which are then used to improve the classification process. When a typical support vector machine (SVM) is compared to UKNN, we find that UKNN outperforms SVM in classification accuracy

Published: February 2024

This study focuses on the root causes for dropping out of the Technical School Leaving Certificate and then suggests to school administration, students and their parents, stakeholders, and further research for the action they need to apply to minimize student dropout from Technical School Leaving Certificate level education. This study was carried out based on an in-depth interview to analyze the cause and process of dropout. The study found different root factors of dropout students, such as - attitude problems, mismatch of curriculum and learning objectives, high expectations, physically disabled, weakness of school administration respect and recognition, laziness, and lack of motivation. On the other hand, dropouts include increased expectations, respect and honor, learning objectives and curricula, physical disabilities, and administrative carelessness. In addition, students are affected by staff behavior, working environment, working mode, and curriculum design, which need to be improved for the school administration and industry to lower the dropout rate.
Presence and Function of Roof Ventilation in Housing Estates in the Humid Tropics
Authors: Kindangen Jefrey I.
Published: February 2024

Traditional Indonesian and Dutch colonial buildings often include an attic for ventilation and natural lighting. However, most Manado homes have corrugated zinc roofs and no attic ventilation. Zinc-roofed building roof ventilation and thermal comfort in Griya Paniki Indah, Taman Mapanget Raya, and Kharisma Koka housings are studied. We created two test cells with and without roof ventilation. A vented ceiling cools the test cell by 1.2 °C during the day. Modern, simple homes with unventilated roofs dominate the three residential districts. All responders reported daytime and nighttime discomfort or excessive temperatures. Residents were striving hard to control the room's environment due to these conditions. Air conditioning, fans, windows, and ventilation are used daily. Thus, attic ventilation benefits must be publicised. This improves building and household energy efficiency and thermal comfort.
Fonética del Himno Nacional del Perú traducido al quechua del Collao: Tratamiento en consonantes eyectivas
Authors: Valdez Luna Pool Kevin
Published: February 2024

El Himno Nacional del Perú traducido al quechua del Collao es una obra que se ejecuta con regularidad en eventos protocolares del país; sobre todo, en la región sur-andina por cantantes profesionales, coros e instituciones públicas y privadas. Esta traducción, sin embargo, presenta dificultades para su pronunciación debido a los fonemas ajenos al español que regularmente son pronunciados con imprecisión, o presenta dificultad técnica, al momento de ejecutarse, entre los no quechuahablantes. La obra se convierte, entonces, en una falencia comunicativa en su interpretación e, incluso, cambia el significado del texto que se recita. El presente estudio aborda el análisis fonético del Himno Nacional del Perú traducido al quechua del Collao con énfasis en la ubicación de los fonemas extraños al idioma español, y con especial atención a los fonemas eyectivos o glotales eyectivos. Estos últimos son explicados en su forma de funcionamiento mecánico sonoro y se dan las pautas necesarias para poder ser ejecutadas a partir de las posibilidades técnicas de los intérpretes. Se han empleado herramientas informativas para contextualizar el trabajo, tales como los antecedentes musicales del Himno Nacional del Perú, los estudios fonéticos sobre el quechua del Collao y la influencia que tienen estos dentro de la ejecución vocal. A continuación, se ha procedido a analizar fonéticamente el Himno Nacional del Perú en el idioma quechua para poder ubicar las consonantes eyectivas. Estas se han contrastado entre tres ejecuciones diferentes y se ha hecho un consenso de los fonemas alófonos que pudieran existir dentro de estas tres ejecuciones para dar una transcripción más acertada de la ejecución sonora. Finalmente, con el análisis hecho, una entrevista realizada a una ejecutante y basándonos en los estudios previos de fonética y canto, se concluye que las consonantes eyectivas causan una fatiga a nivel glotal que podrían perjudicar al cantante a nivel fonético y físico fonatorio durante la realización de su ejecución. Sin embargo, estas consonantes deben ser ejecutadas con la claridad necesaria para ser entendibles por el público oyente, y es responsabilidad del cantante poder encontrar un equilibrio de acuerdo con sus capacidades físicas fonatorias.
La consolidación de la escena de la cueca urbana en Chile y la reactivación de un antiguo circuito musical
Authors: Rohner Stornaiuolo Fred
Published: February 2024

El siguiente artículo propone que en el proceso de consolidación de la cueca urbana en Santiago y Valparaíso (Chile) al iniciarse el siglo XXI, la desaparición de algunos de los referentes más antiguos de la performance de esta variante de la cueca chilena obligó a los nuevos actores y a los nuevos músicos a reactivar los circuitos musicales del siglo XIX por los que este género musical había viajado y se había asentado en Perú y en Chile.
El sentido de patria en dos canciones populares peruanas del siglo XX
Authors: Martínez Espinoza Marino
Published: February 2024

El siguiente texto analiza el sentido de patria que subyace en dos canciones populares peruanas del siglo XX, el vals “Contigo Perú”, de Augusto Polo Campos (Puquio 1932-Lima 2018), y el wayno “Viva la patria”, de Carlos Falconí (La Mar 1937, Huamanga, 2022). Si bien ambas composiciones ocupan temporalidades diferentes y fueron escritas en contextos distintos, el propósito de este artículo es afinar una mirada crítica a través del análisis discursivo sobre el paradigma de patria que construye un sector del criollismo a partir de una retórica del entusiasmo y la unidad de los peruanos en torno de un ideal de integración al Estado-nación, frente al de los músicos andinos, que no solo se sitúa lejos de esa narrativa romantizada sino que expresa frustración y amargura desde su propia experiencia social signada por la práctica de una violencia estructural e histórica en el contexto de la colonialidad, que se concentró especialmente durante el conflicto armado interno.

Un número significativo de mis composiciones ha sido elaborado usando la serie de Fibonacci como elemento estructurador y organizador del discurso musical. Este artículo intenta ser un acercamiento a los procesos compositivos desarrollados por mí a lo largo de más o menos cuatro décadas y converge en el análisis formal de una de las obras más emblemáticas de mi actividad creadora: Algunos poemas de Brindisi para voz, clarinete, violín, chelo y piano, sobre poemas del escritor veracruzano Fernando Ruiz Granados, compuesta en 1994 para el Ensamble Bartók de Chile. En esta partitura, el uso de la mencionada serie numérica incide de modo elocuente en diversos parámetros musicales: ritmo, melodía, armonía, textura y forma.
Transformaciones de la cumbia en la costa norte del Perú en las dos primeras décadas del siglo XXI
Authors: Burgos Segura Oscar Jeanluck , Ñopo Olazábal Víctor Hugo
Published: February 2024

La cumbia ha pasado por distintas transformaciones en la costa norte peruana y mucho se ha escrito sobre sus aspectos históricos y su impacto social. Para su mejor comprensión, es necesario abordar el fenómeno musical en sí mismo. Por ello, el objetivo de esta investigación fue identificar las influencias y características de la cumbia de esta región, a través del análisis comparativo y el paradigma de investigación sobre las artes de tres piezas musicales representativas de este género musical, interpretadas por las agrupaciones Agua Marina, Grupo 5 y Armonía 10. El diseño de investigación estuvo conformado por la aplicación de entrevistas, la transcripción de las grabaciones y el análisis musical comparativo. Los resultados mostraron que la armonía de las piezas, eminentemente tonales, era acórdica con pocas tensiones y bordaduras. Los temas se orientan hacia la melancolía, la decepción, el amor o una historia. Algunas agrupaciones utilizan exclusivamente instrumentos virtuales y electrónicos y, otras, vientos metal con un tratamiento heredado de la salsa. Estos resultados muestran que la cumbia de la costa norte de Perú tiene fuerte influencia colombiana y de géneros caribeños. También se encontraron patrones referentes a la lambada y de compás compuesto, como en el caso del género emergente llamado merequetengue.

Published: February 2024

Este estudio explora las actitudes y comportamientos de maestros hacia cuestiones ambientales y políticas, revelando la complejidad en su postura ética. La investigación se llevó a cabo en tres centros de educación básica del municipio Quevedo, Ecuador. Los datos se recolectaron mediante la aplicación de 115 encuestas a maestros, con preguntas de opción múltiple con escala Likert. Las respuestas de las preguntas fueron analizadas con un Análisis de componentes principales (APC). Previo al análisis, se ejecutaron las pruebas confirmatorias de Kaiser-Meyer-Olkin (KMO) y esfericidad de Bartlett. Los hallazgos de este estudio sugieren que los maestros confían en la capacidad humana para resolver los problemas ambientales y una preferencia por sistemas de gobierno representativos, con una ética influenciada por valores religiosos. Los valores políticos de los maestros guardaron una correlación entre políticas económicas procrecimiento empresarial y actitudes restrictivas hacia la inmigración. Respecto a la gestión y comportamiento ambiental, se observó una actitud favorable hacia prácticas energéticas sostenibles y la conmemoración de días ambientales. Estos hallazgos resaltan la importancia de considerar las actitudes y comportamientos ambientales de los maestros, en la formulación planes de educación ambiental integral, que consideren enfoques antropocéntricos y ecocéntricos para fomentar una sociedad equilibrada con valores ambientales.

Published: February 2024

Hablar sobre la realización profesional en el mundo actual es fundamental, debido a las demandas y desafíos que enfrentan los profesionales en estos tiempos. Si bien los problemas relacionados con la realización profesional pueden variar de un individuo a otro, de un campo laboral a otro o de una nación a otra, existen tendencias y dificultades generales que impactan a un porcentaje considerable de profesionales a nivel mundial. Algunos de estos problemas incluyen la competencia en el mercado laboral, dado que existe una amplia cantidad de profesionales calificados, lo que en ocasiones dificulta que las personas encuentren empleo que se ajuste a sus aptitudes o competencias. Además, los cambios tecnológicos destacan como agentes que pueden provocar que ciertas destrezas profesionales queden desactualizadas con el tiempo. Asimismo, el estrés y dificultades en la salud mental son preocupaciones comunes entre los trabajadores, como consecuencia de las exigencias laborales, con un posible impacto negativo en su bienestar emocional y físico. Un aspecto adicional relevante es la automatización y la inteligencia artificial, las cuales están reemplazando algunas tareas y puestos de trabajo, lo que plantea desafíos en términos de reubicación laboral y adaptación a nuevas funciones.
Dansk statsborgerskab: en gave der ikke er givet
Authors: Olsen Tore Vincents
Published: February 2024

For strammerne i diskussionen om tildeling af dansk statsborgerskab er statsborgerskabet ikke en menneskeret eller noget, man kan gøre sig berettiget til ved at indfri et bestemt sæt af krav. Det er en gave eller et privilegium, som tildeles udlændinge på baggrund af folketingsmedlemmernes gode vilje, hvis og når sidstnævnte føler sig overbeviste om, at førstnævnte genuint bekender sig til de danske værdier og ikke udgør en trussel for demokratiet. I forsvaret for demokratiet og de liberale frihedsrettigheder skal lovgiverne kunne agere suverænt og suspendere alle principper. Derved gentager strammernes position det militante demokratis dilemma: Transformerer forsvaret af demokratiet det til dets modsatte?
Citizens’ choice of daycare provider: A conjoint experiment
Authors: Damgaard Peter Rasmussen , Hjortskov Morten , Holm Jakob Majlund
Published: February 2024

In modern welfare states, citizens’ choice of service providers is consequential for both service quality and the design of public services. Politicians and other central decision makers have a substantial interest in understanding how different factors affect citizens’ choice of service and how citizens make trade-offs between these factors. Using a conjoint experiment on a representative sample of Danish citizens, we study the importance of different organizational factors in the choice of daycare provider. Our results show that all included factors have meaningful effects on the propensity to choose a given provider. However, information about public vs. private ownership does not seem to have an impact on service choice. Additionally, we study whether having a high proportion of staff with pedagogical education can offset the negative impact of a poor staff to child ratio – this turns out not to be the case.
Parliamentary negotiations in Denmark
Authors: Skjæveland Asbjørn
Published: February 2024

Negotiation theory tells us how we should negotiate if we want to negotiate wisely. We learn how to make the cake larger and how to get as big a bite as possible. Negotiations are key in politics. Even so, not many scientific studies apply the negotiation theory framework to legislative negotiations, including Danish legislative negotiations. On the other hand, there is a literature that describes actual legislative negotiations in Denmark. To what extent do the negotiations literature and the described real-life negotiations match each other? Danish politicians can learn from negotiation theory to varying degrees, and negotiation theory can learn from Danish legislative negotiations. The dominant role of the minister in parliamentary negotiations substantially reduces the complexity problems normally associated with multiparty negotiations.

Published: February 2024

Bu çalışma, farklı dönemlerde alınan lavanta (Lavandula x intermedia Emeric ex Loisel) çeliklerine IBA uygulaması ile birlikte farklı yetiştirme ortamlarındaki köklenme durumlarını belirlemek üzere Aralık 2020, Temmuz 2021 yıları arasında serada yürütülmüştür. Deneme; tesadüf bloklarında bölünen bölünmüş parseller deneme desenine göre 4 tekrarlamalı olarak kurulmuştur. Ana parsellere çelik alma dönemi (sonbahar ve ilkbahar), alt parsele IBA (0 ve 1000 mg/l) uygulamaları, en alt parsellere ise farklı köklendirme ortamları (%100 torf; %75 torf + 25 pomza; %50 torf + %50 pomza; %25 torf +%75 pomza; %100 pomza) yerleştirilmiştir. Köklenme oranı (%), çelik başına kök sayısı (adet/çelik), en uzun kök boyu (cm) ölçümleri yapılmıştır. Köklendirme ortamlarına göre en fazla köklenme %89.5 ile torf ortamlarından elde edilmiştir. Çeliklerin alındığı dönemler bakımından ise ilkbahar çeliklerinde %88.6, sonbahar çeliklerinde ise %78.4 oranında köklenme tespit edilmiştir. Hormon uygulaması bakımından köklenme oranı ise IBA uygulanan çeliklerde ortalama %88.2 olurken, hormon uygulanmayan çeliklerde %78.4 olmuştur. Üçlü interaksiyon ortalama değerlerine göre, denemede en yüksek köklenme oranı (%96.0) ilkbaharda alınan ve hormon (IBA) uygulanan çeliklerin, %75 torf + 25 pomza ve %50 torf + %50 pomza ortamına dikilmesiyle elde edilmiştir. En düşük köklenme oranı (% 64.0) ise sonbahar döneminde alınan, hormon uygulanmamış çeliklerin, %100 pomza ortamına dikilmesiyle elde edilmiştir. Ölçülen ortalama en uzun kök boyu (9.55 cm) ilkbaharda alınan ve hormon uygulanmış çeliklerin, %50 torf + %50 pomza ortamına dikilmesiyle elde edilmiştir. Her ne kadar ilkbahar çeliklerinde en iyi sonuçlar alınmış olsa da sonbahar çelikleriyle de tatmin edici miktarda köklenme sağlanabileceği bunun sonucunda da lavanta bitkisinde sonbahar çelikleriyle de üretimin yapılabileceği belirlenmiştir. Özellikle yetiştiricilikte sadece torf ortamının yerine %25 veya %50 oranında pomza ilavesi yapılan ortamların da uygun olduğu tespit edilmiştir.

The Influence of the Translation Tradition on the Construction of Identity: Analysis of the English Translation of Amereida
Authors: Mattioli Virginia
Published: February 2024

This article raises two clusters of decolonial questions. The first is the cluster around the discourse or idea of an 'invention' of America in Amereida, the second includes questions regarding the possibility of a decolonial translation of Amereida. More precisely, the second cluster focuses on how to translate the linguistic multiplicity and multiplicity of ideas present in Amereida in a decolonial way that rejects monological unification and affirms an epistemic and ontological multiplicity. In the article, I try to reveal the coloniality of the epic given that revealing its coloniality is the first step to decolonize.
Amereida: An Ever-Expanding Archive
Authors: Johanson María Teresa
Published: February 2024

The journey of Amereida and the poem Amereida can be read as a project of poetic refoundation of the American continent, which is the foundation of the Open City. They also form the basis of an aesthetic, political and formative project in full force and originate an extensive archive. This article analyzes different dimensions of Amereida in relation to a vast archive of writings, images, displacements and supports in intermediate formats. From this perspective, it is proposed that Amereida exceeds the idea of the archive associated with the preservation of memory to expose a performative condition (Taylor) integrated to the utopian dimension (Groys) with an open character that is projected to the present day. Following these orientations, this article analyzes displacement and travel writing as an archive-repertoire with a performative and digital character. Likewise, the poem Amereida is interpreted as a poetics that reactivates the archive of Latin American literature, at the same time that it elaborates a new literary and visual cartography of the continent. Finally, it addresses the utopian impulse of the foundation of the Open City, from which new media archives derive from gender perspectives. The integration of these dimensions projects the actuality of Amereida and its power to shape an expanding archive.

Published: February 2024

O Estado de Goiás tem recebido um número expressivo de migrantes segundo dados do IBGE (2010). O objetivo deste artigo é, por meio de uma pesquisa bibliográfica, analisar historicamente as políticas públicas voltadas à ocupação e migração para o estado. Os resultados mostram que entre 1970 a 1980 a migração teve fortes influências de políticas públicas de desenvolvimento e agrícolas, de 1980 a 1990 houve apenas um reflexo das políticas anteriores, e de 1990 até 2015 o expressivo crescimento econômico de Goiás é apontado como o principal motivador da migração para a região. O que surge então, nesse novo contexto, é a necessidade de se elaborar políticas públicas que atendam as demandas sociais dessa população de migrantes.
Radiological Risk Assessment of Soil Using RESRAD-OFFSITE Code in Communities around Indorama Fertilizer Company Eleme, Port-Harcourt, Rivers State, Nigeria
Authors: Furo Evelyn V. , I.A. Hart  , Ononugbo Chinyere P.
Published: February 2024

Anthropogenic activities around a fertilizer company can cause elevation in the concentration of naturally-occurring radioactive materials (NORMs) within surrounding soils, as a result of effluent discharge or heaping of rocks used as raw materials. The aim of this study was to evaluate the human risk associated with exposure to NORMs in soils from communities around Indorama Fertilizer Company Eleme, Port-Harcourt, Rivers State, Nigeria. A sodium-iodide doped with thallium [NaI(TI)] detector was used to measure activity concentrations of these NORMs in 22 soil samples within the study area. The residual radioactivity (RESRAD) offsite modeling program(version 4.0) was then used to estimate the radiation doses and the cancer morbidity risk of uranium-238 (238U), thorium-232 (232Th) and potassium-40 (40K) for hypothetical resident farmer scenario. According to the RESRAD prediction, the maximum total effective dose equivalent (TEDE) during 100 years was found to be 2.82 x 10-5 mSvy-1 at year 12, while the maximum total excess cancer morbidity risk for all the pathways was 3.52E-08 at year 6. Therefore, results obtained from the RESRAD-OFFSITE code in this study has shown that the health risk from effluent discharge within the study area is within acceptable levels according to international standards.

Sugarcane is a clonally propagated crop and genetic improvement involves crossing of diverse species of Saccharum clones. Identification of desirable cross combination is one of the essential steps in the development of superior varieties. This study was conducted with an objective of identification of best cross combination based on their ability to produce superior clones by contributing desirable traits and suitability of a parental stock as “FEMALES” or “MALES” based on their ability to transmit positive genes to progeny. Sixteen biparental crosses with minimum of 20 progenies were screened for NMC (≥10) and HR Brix (≥20 units) in first clonal selection. The significance of parental stocks performance in cross combination was tested using “t‟ test assuming unequal variance. Progenies obtained from Co 06015, Co 0241 and Co 8347 recorded 20.99%, 20.82% and 20.81% of HR Brix, while Co 0209, Co 06015 and Co 94008 recorded 14.23, 12.76 and 11.88 of mean NMC when they used as male in crossing. Clones derived from Co 99006, Co 0403 and Co 06002 showed 20.93%, 20.82% and 20.81% of HR Brix, whereas Co 07010, Co 99006 and 2007-285 recorded 13.68, 12.21 and 11.40 mean NMC when they were used as female in crossing. Crosses viz., Co 99006 x Co 06015, Co 0403 x Co 0241, 2007-285 x Co 0209 and Co 94005 x Co 86011 has contributed 63%, 32%, 30% and 28% desirable selections respectively. The clones Co 06015 and Co 99006 are proven male and female can be used abundantly in crossing for the development of superior clones. The clones Co 8347, Co 0241, Co 0209 and Co 94008 are best males, whereas Co 0403, Co 06002, Co 07010 and 2007-285 are best females need to be crossed extensively for the development of superior varieties combining quality and cane yield traits.

Published: February 2024

This paper investigates the digital transformation of libraries in the Indian context, employing a systematic review and quantitative analysis of existing literature. The inclusion criteria encompass scholarly articles, conference papers, and reports published between 2010 and 2023, with a focus on quantitative analyses of digital transformation in libraries. The findings reveal a substantial increase in government funding, driving a 40% rise in digitization projects across universities. Notable success stories include Radio Frequency Identification (RFID) implementations, yielding efficiency gains and reduced book losses. However, challenges persist in balancing physical and digital resources, as evidenced by a 30% decline in physical book checkouts. Cultural nuances impact user preferences, necessitating strategic content acquisition policies. The study also highlights the importance of addressing the digital divide through targeted digital literacy initiatives. As Indian libraries navigate this complex terrain, a synthesis of qualitative and quantitative insights provides a roadmap for an inclusive and dynamic future.

Control, 50% NPK, 100% NPK, 150% NPK, 100% NPK+ZnSO4@ 10kgha-1,100% NP, 100% N, 100% NPK + FYM @5t ha-1, 50% NPK+BGA@ 10kg ha-1 and 50% NPK + GM @40kg ha-1. The results showed that the physical properties like total porosity, gravimetric and volumetric moisture content, hydraulic conductivity, infiltration rate, water stable aggregates and mean weight diameter of the soil were increased, while the bulk density was reduced significantly with the 100% NPK FYM treatment over all other treatments. However, the use of imbalanced (100% N and 100% NP) fertilizer, super optimal (150% NPK) and sub optimal (50% NPK) rate of inorganic fertilizer as compared to the unfertilized control showed significant effect on the physical properties of soil. Integrated nutrient management practice including FYM and recommended dose of NPK showed as best treatment with respect to growth and yield parameters like plant height, no. of tillers and no. of grains as compare to other treatments. The grain (5065 kg ha-1) and straw (7075 kg ha-1) yield of rice was registered higher in 150% NPK treatment followed by 100% NPK FYM treatment (4855 kg ha-1 and 6565 kg ha-1) and lowest in control treatment (2350 kg ha-1 and 2680 kg ha-1).

Background: Malaria is one of the most important public health and life-threatening parasitic infections caused by the protozoan parasite- Plasmodium. The WHO Global technical strategy for malaria 2016–2030, updated in 2021, provides a technical framework for all malaria-endemic countries. It is intended to guide and support regional and country program as they work towards malaria control and elimination.

Objectives: This study assessed the prevalence of malaria in toddlers in a tertiary health facility in developing countries between January and December 2021.

Methodology: The study involved the use of patient’s case notes, A total of 104 case notes were selected using simple random technique. A checklist was generated from the collection of data. Data was analyzed using the statistical package for scientific solution (SPSS) software version 21.0. for descriptive statistics. The Chi square test was used to test for associations. The level of significance was set as P < 0.05.

Results: It was discovered that Half (50%) of the toddlers were 2years old, a little above half (52.9%) were male and the mean age was 2.31 with a standard deviation of 3.02. studies. On the financial implication of malaria treatment study revealed that 76.9% spent between ₦1500 -  ₦1900 and artesunate was the most common antimalarial used and most children spent up to 3 days on admission

Conclusion: Findings from this study reveals that the prevalence is common among toddlers especially in 2years old. The average amount spent on antimalarial purchase is relatively fair based on the drugs the patients can afford. The highest prevalence was seen in July (62%) and the least prevalence was seen in January (30%).

This work describes scanning electron microscope and XRD characterization of untapped clay deposits in Itu Local Government Area Akwa Ibom State and its potentials as raw material for petroleum refining. The structure and morphology of the raw kaolin clay and metakaolin were analyzed using XRD and SEM. The XRD data indicates 48.0 % quartz, 30.0% kaolinite, 3.0 % chlorite, 16.0 % illite and 2.0% albite in the raw kaolin and 68.3 % quartz, 17.3 % orthoclase, 5.9 % muscovite, 1.8 % illite , 6.68 %, albite in the metakaolin from Ikot Uso Akpan and 16.2 % kaolinite, 67.0% quartz, 2.5 % muscovite, 5.5 % orthoclase, 1.4 % chlorite, and 7.0 % albite were revealed in  Ekim Itam raw kaolin. 66.0 % quartz, 10.0 % muscovite, 15.0 % orthoclase, 5.0 % illite, 5.0 % albite were recorded in the metakaolin. The XRD results confirmed the presence of quartz and alumina mineral phases from both kaolin deposits. Calcination at 1000oC increased the crystalline structure of the metakaolin and did not significantly modify surface morphology of the kaolin indicating stability of kaolin structure, one the desired property of a good zeolite. The SEM results indicated heterogeneous size and spongy like porous shape. There was no significant change in the surface morphology of the heterogeneous size calcined kaolin compared with untreated kaolin.  The SEM results of the metakaolin kaolin also indicated cubic crystalline structure with well-defined edges. With adequate modification the studied kaolin could be a promising raw material for synthesis of zeolite suitable for bio and fossil fuel processing.

Published: February 2024

Keterampilan literasi dan karakter merupakan salah satu keterampilan abad 21 yang sangat diperlukan. Namun, pada faktanya kondisi literasi anak di Indonesia masih sangat rendah. Terkhusus di Surabaya, tingkat minat baca masyarakatnya ada di angka 64,7%. Namun, angka ini masih dirasa kurang dan belum tersebar di seluruh wilayah Surabaya. Khususnya di lingkungan yang kurang mendapatkan perhatian lebih mengenai hal ini. Seperti di lingkungan Gang Dolly Surabaya, masih didapati anak-anak usia dini yang tidak memiliki literasi bahasa dan karakter yang baik. Selain itu, tidak semua orang tua memiliki kesadaran akan pentingnya keterampilan ini untuk dimiliki anak mereka sejak dini. Melihat pentingnya melatih keterampilan literasi dan karakter sejak dini, maka diadakanlah program pengabdian masyarakat (PkM) yang dirancang dan dilakukan untuk menolong para orang tua dan juga anak usia dini untuk mengembangkan kemampuan literasi dan karakter sejak dini. Tahapan yang dilakukan dalam kegiatan ini adalah melakukan persiapan dengan melakukan riset mengenai pentingnya keterampilan literasi bahasa dan karakter anak sejak dini dan cara mengembangkannya. Setelah itu dilakukanya kegiatan survei dan percakapan dengan pihak PAUD dan Ketua RT di Gang Dolly. Setelah menemukan permasalahan dan usulan kegiatan, maka tim PkM melakukan persiapan kegiatan. Kegiatan pun akhirnya diadakan dua kali pertemuan yang berisikan materi mengenai pentingnya bercerita kepada anak-anak dan memperkenalkan cara praktis orang tua untuk nantinya dapat meningkatkan kemampuan literasi dan karakter anak. Kegiatan ini meliputi kegiatan parenting class dan kegiatan bersama anak-anak yaitu kegiatan bercerita, menggambar, dan juga melakukan aktivitas pendukung lainnya. Kegiatan ini dilakukan pada dua tempat yang berbeda di Gang Dolly Surabaya, yaitu PAUD Cahaya Bunda dan TK Hati Bapa. Selain memberikan materi dan kegiatan pada orang tua dan anak, program pengabdian masyarakat ini juga memberikan fasilitas penunjang literasi bahasa anak berupa pojok baca untuk kedua lembaga PAUD di sana. Setelah kegiatan berlangsung, tim melakukan evaluasi akan kegiatan tersebut kepada para peserta dan pengelola PAUD yang ada. Hasilnya menunjukkan bahwa kegiatan ini memberikan dampak kesadaran pada orang tua dan pendidik PAUD akan pentingnya keterampilan literasi dan karakter anak meningkat. Anak-anak juga mendapatkan exposure akan kegiatan yang mengembangkan keterampilan literasi yang menyenangkan.
Spinning the stories of our lives
Authors: Marsh Elizabeth J. , Tversky Barbara
Published: June 2004

The way people talk about past events can affect the way they remember them (Tversky & Marsh, 2000). The current research explores how people naturally talk about events from their own lives. Participants recorded what, when, and how they told others about events from their lives. In general, participants talked about recent emotional events, and told them primarily to peers in order to convey facts and/or to entertain. Not all distorted retellings were regarded as ‘inaccurate.’ Participants labeled 61% of their retellings as distorted (containing exaggerations, omissions, minimizations, or additions) but only 42% of their retellings as inaccurate. Social context shaped the stories people told: they changed stories for different audiences; they exaggerated to entertain and simplified to inform. People construct stories as they retrieve and use memories in a social context. Copyright © 2004 John Wiley & Sons, Ltd.
Delaying execution of intentions: overcoming the costs of interruptions
Authors: McDaniel Mark A. , Einstein Gilles O. , Graham Thomas , Rall Erica
Published: June 2004

In real‐world settings, execution of retrieved intentions must often be briefly delayed until an ongoing activity is completed (delayed‐execute prospective memory tasks). Further, in demanding work settings, the ongoing activity itself can be interrupted. Experiment 1 examined the effects of the delay length (5, 15, 40 s), the presence of an interruption within that delay, and the length of the interruption on prospective memory performance. Delay length did not significantly affect performance, but interruptions produced significant decrements in performance relative to a delay alone. The length of the interruptions (10 vs. 20 s) did not significantly affect performance. Experiment 2 replicated the negative effects of interruptions, and found that these effects could be overcome with a simple external mnemonic. We suggest that in demanding work environments where interruptions are likely, external cues are advisable, especially where prospective memory failures have critical consequences.

Timing moderates the effects of repeated suggestive interviewing on children's eyewitness memory
Authors: Melnyk Laura , Bruck Maggie
Published: June 2004

The relative role of the timing and repetition of misinformation on the accuracy of children's recall was examined in two experiments. Kindergarten children participated in a magic show and about 40 days later had a memory test. Between the magic show and the memory test, the children were suggestively interviewed either one time in a relatively ‘early’ interview (temporally closer to the magic show than the memory test) or a relatively ‘late’ interview (closer to the memory test than the magic show), or in both suggestive interviews. The timing of the suggestive interviewing was manipulated so that the interview was temporally distant from the event or memory test or temporally close to the event or memory test. Repeated interviewing heightened misinformation effects only when the children received the two interview sessions temporally close to the event and memory test.

Chemie: auf zu neuen Zielen – Gedanken zur Zukunft der Chemie
Authors: Whitesides George M.
Published: June 2004

Sind Überlegungen zur Zukunft relevant oder dienen sie nur der Zerstreuung? Regelmäßig werden wichtige Grundüberzeugungen aufgrund wissenschaftlicher Erkenntnisse verworfen, mit oft tiefgreifenden Folgen für die Gesellschaft. Falsche Annahmen lassen sich im Nachhinein leicht ausmachen, aber lassen sie sich auch in der Gegenwart erkennen, und lassen sich aus der Erkenntnis Schlussfolgerungen für die Zukunft ziehen? Dieser Essay diskutiert gesellschaftlich akzeptierte Annahmen und das Potenzial der Naturwissenschaften, sie zu widerlegen.
Preparation and properties of methyl methacrylate and fluoroacrylate copolymers for plastic optical fiber cladding
Authors: Choi Dong‐il , Yeom Eun Hee , Park Min , Kim Jun Kyung , Kim Byoung Chul
Published: June 2004

Copolymers of methyl methacrylate (MMA) and fluoroacrylate (FA), with different FA content (0–100 wt %), were prepared by bulk polymerization. The chemical structure was identified by 1H‐NMR and other physical properties were measured by DSC, Abbé refractometer, X‐ray diffractometry, polarized optical microscopy, and DMA. The copolymers were confirmed as random copolymers by Fineman–Ross analysis and first‐order Markov statistics. Increasing the FA content from 0 to 100 wt % decreased the refractive index from 1.492 to 1.368. Copolymers with FA content higher than 70 wt % crystallized and led to low transparency and poor thermal properties. On the other hand, copolymers with FA content lower than 70 wt % was thermally stable (Tg was as high as 60°C) and transparent. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 2082–2089, 2004
