Fatigue Testing and Modeling of Bonded Composite Specimens in Mode I, II, and Mixed-Mode I/II Loadings
Authors: Li Gang , Renaud Guillaume , Li Lucy , Liao Min
Published: February 2024

Fatigue debond growth of bonded composite specimens in mode I, mode II, and mixed-mode I/II loadings were studied experimentally and numerically. For the mode I loading, test data sets were analyzed under the linear elasticity condition. For the mode II and mixed-mode loadings, specific test data processing was used to ensure that nonlinear effects that act outside of the cyclic loading range are excluded from the fatigue behavior assessment. An important finding under the mode II and mixed-mode loadings is that the actual loading ratios in the tests varied and were different from the applied displacement ratio. The experimental characterization of the fatigue debond behaviors was complemented with numerically determined correlations between the compliance and debond length under each individual loading. This correlation was used to determine an effective debond length from the compliance determined experimentally. According to the actual loading ratio variation, the fatigue growth behaviors were characterized using Paris’ law. Numerical fatigue analyses using two codes, Abaqus finite element (FE) and AFGROW, were carried out and validated using the developed test database. The details on an FE model setup and analysis strategy for a mixed-mode specimen are presented. Good agreement in the fatigue lives was obtained between the test and numerical analyses for the three types of loading. Also, good agreements in the load versus debond growth length relations were obtained between the test and FE analysis in the mode II and mixed-mode loadings. Reasons for the result discrepancy are discussed. The study shows that the presented analysis procedure is effective. The thorough description of both the used test data processing and numerical analysis procedure fills a knowledge gap in the available literature.

Relatos escolares y construcción del currículum en la formación inicial del profesorado. Bioeducamos.
Authors: Márquez García María Jesús , Prados Megías María Esther , Padua Arcos Daniela
Published: January 2024

Bioeducamos es una propuesta que plantea desarrollar una concepción dialógica e intersubjetiva del conocimiento y del aprendizaje desde dos principios esenciales: la experiencia escolar como principal fuente de conocimiento profesional de los futuros docentes y el aprendizaje desde una construcción colectiva y cooperativa entre alumnado y profesorado. A partir de los relatos escolares del alumnado, en un proceso de intercambio, categorización y sistematización colectiva de los mismos, se dialoga con los textos académicos y científicos para elaborar una visión propia, comprensiva y compartida del currículum formativo y de la realidad de la escuela y del currículum que en ella se desarrolla.

How much space is needed for biodiversity conservation?
Authors: Trifanova M. , Zadorozhna G. , Novitsky R. , Ponomarenko O. , Makhina V. , Khrystov O. , Ruchiy V. , Zhukov O.
Published: January 2024

The EU's 2030 Biodiversity Strategy and the Kunming-Montreal Global Biodiversity Framework call for 30% coverage of land and sea protected areas and strict protection for 10% of land area to prevent and reverse biodiversity loss. Ukraine has declared its aspiration to integrate into the European Union and must back up its statements with action and do everything to achieve such ambitious conservation goals. Like many European countries, Ukraine faces great challenges on this route. The significant level of anthropogenic transformation of the territories makes it very difficult to find new areas to expand the boundaries of the nature reserve fund. The practical steps to create nature reserves are significantly limited by legal mechanisms that guarantee land users' ownership of the relevant land plots. An important task in nature conservation is to develop indicators that can clearly and easily demonstrate the importance of areas for conservation. Such tools are necessary to convince policy makers and land users of the need to protect the relevant areas. The indicators of importance for biodiversity conservation should be scale-independent, as both large areas and small areas are important for conservation. In this article, we consider the case of a project to expand the boundaries of the Dnipro-Orylskiy Nature Reserve by adding five areas directly adjacent to it. The number of species included in the various Red Data Lists was chosen as an indicator of the conservation value of the territory. The species-area relationship was used to assess the role of scale. The number of species on the Red Lists was considered instead of the classical relationship that considers the total number of species in a community. The normalised deviation from the regression relationship was considered as an indicator of the conservation value of the respective area, which is statistically independent of the area of the site. The different Red Lists are compiled according to different criteria, so the indicator of conservation value for each Red List focuses on the relevant conservation aspect. The results of the conservation value assessment can be presented graphically, which clearly demonstrates the role of the respective areas in the maintenance of biological diversity. The proposed algorithm for assessing conservation value can be applied to a wide range of environmental protection tasks. In terms of further research, it is important to assess the role of ecosystem function assessment in the design of protected areas.
Efficacy and clinical potential of phage therapy in treating methicillin-resistant Staphylococcus aureus (MRSA) infections: A review
Authors: Fortaleza Jamil Allen G. , Ong Christian Joseph N. , De Jesus Rener
Published: February 2024

Staphylococcus aureus infections have already presented a substantial public health challenge, encompassing different clinical manifestations, ranging from bacteremia to sepsis and multi-organ failures. Among these infections, methicillin-resistant S. aureus (MRSA) is particularly alarming due to its well-documented resistance to multiple classes of antibiotics, contributing significantly to global mortality rates. Consequently, the urgent need for effective treatment options has prompted a growing interest in exploring phage therapy as a potential non-antibiotic treatment against MRSA infections. Phages represent a class of highly specific bacterial viruses known for their ability to infect certain bacterial strains. This review paper explores the clinical potential of phages as a treatment for MRSA infections due to their low toxicity and auto-dosing capabilities. The paper also discusses the synergistic effect of phage-antibiotic combination (PAC) and the promising results from in vitro and animal model studies, which could lead to extensive human clinical trials. However, clinicians need to establish and adhere to standard protocols governing phage administration and implementation. Prominent clinical trials are needed to develop and advance phage therapy as a non-antibiotic therapy intervention, meeting regulatory guidelines, logistical requirements, and ethical considerations, potentially revolutionizing the treatment of MRSA infections.
Use of malted pulses to formulate gluten-free fresh-egg pasta
Authors: Cimini Alessio , Poliziani Alessandro , Morgante Lorenzo , Moresi Mauro
Published: February 2024

In spite of the fact that legumes are rich in proteins, dietary fibers, and micronutrients, their average per capita consumption is limited because of their lengthy cooking period, unpleasant flavor, low-digestible proteins, and gastrointestinal problems. This study was aimed at assessing the effectiveness of the malting process of three typical pulse seeds of the Italian Latium region (i.e. Gradoli Purgatory beans [GPB]; Onano lentils [OL]; and Solco Dritto chickpeas [SDC]) to minimize their anti-nutrient content and test their use as ingredient in the preparation of gluten-free fresh egg pastas. All these fresh egg pastas were devoid of flatulence-inducing oligosaccharides with low phytate content (0.6–0.80 g/100 g of dry matter, dm), a crude protein content of around 20 g/100 g dm and in vitro glycemic index ranging from 28% to 38%. However, the only fresh egg pasta, including malted GPB flour, exhibited not only a significantly smaller glycemic index (28%±3%) but also a resistant starch–total starch ratio by far greater than the threshold value (14%) specified by the European Commission Regulation 432/2012 to label foods with the health claim indicating improvement in postprandial glucose metabolism.

Aim. To analyze the prevalence of smoking according to the Epidemiology of Cardiovascular Diseases and their Risk Factors in Regions of Russian Federation-3 (ESSE-RF3) study, and compare these data with the previous two stages.

Material and methods. Data from following three cross sections of the ESSE-RF study were used: 2013-2014, 2017, 2020-2022. At the first stage, the prevalence and probability of smoking was assessed according to ESSE-RF3 data in 2020-2022 (n=28628, 35-74 years). At the second stage, an analysis was carried out over time using data from all three ESSE-RF sections (n=43804, 35-64 years).

Results. In the overall ESSE-RF3 sample, the prevalence of smoking was 17,0% (men — 27,7%, women — 7,6%). Smoking probability varies significantly by sex, age, education level and income. Over time, the standardized prevalence of smoking increases from 25,0% in 20132014 to 26,2% in 2017, and then decreases to 21,5% in 2020-2022. Women are characterized by the same direction of trends, while men had consistent decrease in prevalence from 41,3 to 37,0 and 34,3%, respectively. The probability of smoking in 2017, relative to 20132014, decreases only in some socio-demographic categories of the population. In 2020-2022, a decrease in the probability of smoking is typical for both the general sample and all subgroups of the population.

Conclusion. The results obtained characterize the current situation and time trends of the last decade and contain important information on smoking epidemiology in Russia.
The Directionality of Practices in the Definition of “Solidary”, “Anthropophagic”, or “Foreign” Consumption Patterns in the Space
Authors: Costa Breno Giordane dos Santos , Pinto Marcelo de Rezende
Published: February 2024

Abstract In the present paper, we demonstrate that the work developed by the Brazilian geographer Milton Santos is suitable for studies in the field of practices and consumption. When we use the term ‘practice’ we are referring to a specific kind of practice that is found in the strand of theory created by Schatzki’s work. More specifically, with this merge, we created the construct of directionality of practices. Looking at this dimension, the researchers can see the origin of practices and the consequent consumption patterns in the places. As we argue, “solidary” consumption is created by horizontal practices, “foreign” consumption is created by vertical practices, and “anthropophagic” consumption is created by undifferentiated practices. We expect that this paper can also contribute to giving room for Milton Santo’s work in the field of consumption studies.
“Making Sophisticated Lemonade out of Lemons”: Gender and Race in Organizing Everyday Culinary Practices
Authors: Borsatto Andiara Rosa dos Santos , Fantinel Letícia Dias
Published: February 2024

Abstract This article aims to understand the organization of everyday life from the dynamics of gendering and racialization of cooking/eating practices engendered by ordinary managers. To do so, we problematize organization in a procedural and micropolitical ontology that allows to highlight how everyday cracks cross and give rise to practical rearticulations of a tactical and strategic nature. Narratives from ordinary black managers were captured and analyzed using the dialogic narrative technique, in the search for articulating the participating subjects’ voices with those of the authors of the text, the adopted theoretical framework and the readership. Our findings unveil the kitchen as a central organizational space for understanding these ordinary practices (although sometimes invisibilized and silenced), in heterogeneous processes of apprehension of culinary know-how, as well as in dynamic tactical and strategic articulations for survival purposes. Due to the moment in which the field research took place, the narratives describe these articulations amid the impacts caused by the covid-19 pandemic on the daily lives of the managers researched. Empirically, this study contributes by showing the heterogeneity in the organization of practices that constitute ordinary management, and which, in the context of a pandemic, produced narratives that differ from a hegemonic narrative of rupture, but which nevertheless impact on everyday life and give rise to reconfigurations. Theoretically, we contribute by showing how practices articulate apparently opposing repertoires such as private and public, sociability and business in everyday life. We have therefore advanced in understanding the organization of practices as constituents of ordinary management, in particular, from the crossings produced by the categories of race and gender that engender survival tactics and strategies.

Abstract Objective To reflect on the interrelations between Florence Nightingale's Environmentalist Theory and the Ecosystem Theory and their influences on the reparative process of diseases and on the health/disease/care of human beings. Method A theoretical-philosophical reflection on the interrelations between Florence Nightingale's Environmentalist Theory and the Ecosystem Theory, based on authors who discuss this topic. Results Both theories are similar in relation to the search for self-knowledge, self-organization/autopoiesis and the way to visualize the components of reality in human life and its interactions with the environment. Both involve the totality of the environment's biotic and abiotic organisms, and consider that they interrelate, influence, cooperate and interfere in human life. Conclusion and implications for the practice The interrelations between both theories make it possible to construct, in a holistic way, new knowledge about human beings' thinking, seeing, feeling and acting in the universe and of Nursing care, thus apprehending the totality of the needs, and the integration and dynamic balance of being and living healthy.

Some Observations on Cultural Memory, the Hebrew Bible and the History of "Ancient Israel"
Authors: Pfoh Emanuel
Published: February 2024

Cultural memory as an interpretive concept has had in recent years a concrete impact in Hebrew Bible/Old Testament historical studies. Its main contribution has been to discuss how and to what degree the different evocations (memories) found in the biblical narrative relate both to the history of the production of the biblical texts in antiquity and to the history of "ancient Israel" in the southern Levant, especially during the first millennium B.C.E. The present contribution offers some observations on the matter, essentially from the perspective of social anthropology and critical historiography, reviewing the main aspects of the uses of cultural memory in biblical scholarship, while making some epistemological and methodological observations and proposals.
The Narrative Significance of the Role of Abraham in the Identity of the Visitors in Genesis 18-19
Authors: Ndele Michael Chris
Published: February 2024

The identity of the visitor(s) of Abraham and Lot in the Mamre-Sodom story is characterised by ambiguity, which makes it difficult to determine the actual visitor in the narrative. This article therefore employs narrative critical analysis to examine the role of Abraham in relation to the visitor-identity question in the story. Abraham is mentioned in both the Mamre and Sodom accounts and he is arguably the reason for the visit in Gen 18-19. He initiates the departure to Sodom (18:16), he reappears to survey the destruction of Sodom and Gomorrah (19:27) and, lastly, the Sodom episode concludes with him (19:29). Moreover, there seems to be a special relationship between Abraham and the visitor(s) as shown by the verbs מין (18:19), מיןמין (18:19) and מין(19:29). Abraham's significant role throughout the Mamre-Sodom narrative can be seen as a catalyst for identifying the visitor as probably YHWH.
The Joint Reaffirmation of the Davidic Messiah and the Torah of Moses in Deuteronomy 32, As in the Psalter
Authors: Gosse Bernard
Published: February 2024

Proverbs 30:3-5 depends on Job 38-39, hence, the use of the divine name Eloah in Prov 30:5. We note the same in Ps 18:31 but with the substitution of the name of YHWH for Eloah, as part of the messianic Yahwist reaffirmation of the writing of the whole Psalter. In this perspective, Ps 18:32 identifies Eloah with YHWH. In the parallel of 2 Sam 22 to Ps 18, the name Eloah is not repeated, the emphasis being on the relationship between David and the Psalter. Deuteronomy 32 agrees with the overall redaction of the Psalter, which jointly reaffirms the Davidic Messiah and the Torah of Moses, in the general introduction (Ps 1, the Torah and Ps 2, the Messiah), in the first Book, Pss 3-41 (Ps 18, the Messiah and Ps 19, the Torah) and the fifth Book, Pss 107-150 (Ps 119, the Torah and Pss 120-132, the Messiah). Thus as inclusion, Deut 32:2-4 is based on Ps 18:31-32 with the reference to YHWH the ROCK, an allusion to the Temple and its cult, including the performance of the Psalter. The vocabulary of this passage from Ps 18 appears again in the following verses of Deut 32, including the name Eloah in Dt 32:15, 17, its only occurrences in Deuteronomy.

Of the amphibian orders, the Gymnophiona (caecilians) have the lowest number of species and are the least known. We report new information on the morphology, biology, range, and distribution of Ichthyophis kodaguensis, a striped ichthyophiid caecilian from the Western Ghats, India that shows the first evidence of possible sexual-dimorphism in this species. Based on the clutch size, limited range, relatively low fecundity, and agricultural practices in their habitats, we consider that I. kodaguensis is highly threatened when compared to other striped ichthyophiids from the Western Ghats, a biodiversity hotspot.

The Impact of Rotation Model on Minimizing Inflectional Morphemes Errors in English Writing: A Comparative Study of Error Analysis
Authors: Usama Mohammad , Alam Sohaib , Tarai Shashikanta , Banu Sameena
Published: February 2024

The study aims to analyze 12th-grade students’ writing errors related to inflectional morphemes. In addition, the research measures efficacy of the Rotation Model (RM) and the Grammar Translation Method (GTM) in minimizing writing errors among learners of English. Comparative studies are rare to find the effectiveness of two teaching models in the context of error analysis. Eighty-two samples were taken into consideration for randomize sampling. The present research is divided into two groups; the experimental group, consisting of 41 participants, provided with instruction via RM, and the control group, also comprising 41 individuals, being taught through GTM. Pre and post-test treatment data were collected and analyzed with the help of SPSS 22. The results revealed common errors with inflectional morphemes among both groups. Additionally, the mean values for each type of error were significantly minimized due to the post-instruction of RM compared to the GTM. The study’s findings largely devoted to pedagogical improvement among ESL learners’ writing. The findings are reviewed concerning future research directions and instructional strategies.
A New Historicist Reading of John Dos Passos’ Novel The Big Money: Depiction of Children as a “Second Lost Generation”
Authors: Al-Tarawneh Anoud Ziad
Published: February 2024

This article examines the representation of children as a “second lost generation” in John Dos Passos’ novel The Big Money. It explains that the documentary and narrative sections that Dos Passos integrates into the novel explore how children’s position in the 1930s is caught between parents’ care and indifference. Dos Passos clarifies the impact of the American Dream and materialism upon the structuring of this conflicted position. In the novel’s Newsreels, Dos Passos presents a composite of popular songs and news headlines that present children seeking jobs and also departing from their family houses. Alongside the presentation of this phenomenon which resonates with children’s social situation in 1930s, in the narrative sections Dos Passos portrays Juvenile characters as living in families whose main concern is the making of money. To investigate this representation, the article considers the views of historians about the first “lost generation” (the post-World War I generation). It utilizes the “second lost generation” term to describe the juveniles who struggled during the 1930s age of Depression. The article historicizes the position of children in 1930s America. It refers to literary critics’ views about Dos Passos’ modernist and political inclination. The article concludes that Dos Passos’ The Big Money manifests in a modernist form fragmented historical realities about 1930s America’s materialistic thinking, within which children are seen as a second “lost generation”.

Published: February 2024

En proyectos hidroeléctricos se han realizado pocas investigaciones para determinar la composición taxonómica de dípteros de la familia Psychodidae, subfamilia Phlebotominae. En este trabajo se realizó un inventario taxonómico de flebótomos en el área de influencia de la central hidroeléctrica de Ituango, departamento de Antioquia con el fin de actualizar su distribución y resaltar su importancia médica como vectores del protozoo del género Leishmania. Para esto, se realizaron monitoreos entomológicos con trampas CDC y trampas Shannon, en diez municipios de la subregión occidente (Santa Fe de Antioquia, Peque, Olaya, Liborina y Sabanalarga) y de la subregión norte (municipios de Ituango, Briceño, Valdivia, Toledo y San Andrés de Cuerquia). Para la identificación taxonómica se utilizaron las claves de Young y Duncan y Galati. En total se recolectaron 7993 flebótomos, distribuidos en 39 especies según Galati, destacándose seis especies consideradas vectores de especies de Leishmania, que causan la leishmaniasis cutánea. Estas especies fueron Lutzomyia (Trl.) gomezi, Lu. (Hel.) hartmanni, Psychodopygus panamensis, Pintomyia (Pif.) columbiana, Nyssomyia. trapidoi y Ny. yuilli yuilli. Los datos indican que la zona de muestreo es endémica para la leishmaniasis debido a la presencia de vectores transmisores de este parásito. El inventario sobre la distribución de flebótomos servirá de base para estudios posteriores que permitan la implementación de estrategias de vigilancia y control.

Introducción: debido a la pandemia se presentaron desafíos académicos y se recurrió al uso de la simulación virtual para sustituir las experiencias clínicas que se suspendieron, lo que ofreció estrategias de aprendizaje innovadoras y una estandarización de la enseñanza.Objetivo: comparar la percepción y el nivel de satisfacción en la adquisición de conocimientos, habilidades y destrezas mediante la simulación en modalidad presencial y virtual de los estudiantes de medicina.Métodos: estudio transversal analítico que incluyó estudiantes de medicina que recibieron prácticas de simulación virtuales y presenciales. Posterior al aval ético y a la firma del consentimiento se aplicó una encuesta para indagar las características sociodemográficas y académicas del estudiante, las condiciones físicas de la institución, la autoevaluación frente a la adquisición de habilidades técnicas y blandas y la calidad y satisfacción con la simulación clínica.Resultados: se incluyeron 105 estudiantes con mediana de edad de 22 (RIC: 21 - 23 años), quienes manifestaron una mayor adquisición de habilidades técnicas mediante la simulación presencial frente a la virtual. De manera presencial se obtuvo un 85% de dominio de algunos temas en comparación con la virtualidad (65,7%, p < 0,001). Sin embargo, en el escenario de presentación y dosis de medicamentos, el 80% refirió dominio del tema mediante la práctica virtual comparado con el 53,3% en la modalidad presencial (p < 0,001). El desarrollo de habilidades blandas fue similar en ambos escenarios, como fue el caso de resolución de problemas (83,8%), comunicación efectiva (78,1%), entre otros.Conclusiones: la simulación clínica es clave para la formación médica y su aplicación presencial es percibida como la forma más adecuada de emplearla en el entorno educativo.

Authors: Gonzalez Leonardo José , Kalenatic Dusko , Moreno Karol Vivivana
Published: January 2024

This paper presents the implementation of the integral and dynamic methodology in the scheduling and dynamic control of projects. For this purpose and using the above-mentioned methodology, a model which combines activity networks AON (activity on node), CPM, multimode execution and system dynamics is developed. The model is operationalized by developing two separate networks, i.e., a scheduling network on the one hand and the execution network on the other hand, in order to interact through a control loop. The proposal is validated using activity networks with 16 activities selected from MRCPSP of PSPLIB library. The model derived from the methodology has significant advantages in characteristic indicators of the project management. The paper concludes with a proposal of new combinations of tools, which, together with the methodology, can address problems of scheduling and control of projects with greater variability and complexity.
Analysis of the elastic-plastic behavior of pressurized internal cracks in welded joints of low carbon steel pipes
Authors: Fernández Cueto Martín Julián , González Velázquez Jorge Luis
Published: January 2024

It was analyzed the elastic-plastic behavior of areas with pressurized planar internal cracks extending from the pattern metal region in the heat affected zone to the welding metal in welding joints of low carbon pipes subject to internal pressure. Using the ANSYS 8.0[TM] software, three-dimensional simulation of geometrical models of pipes containing the internal pressurized cracks was performed. The finite element method with non linear strain conditions was employed, considering the kinematic hardening rule and the real material properties for every location. The fracture paths and expressions to calculate the pressure in the crack and in the pipe that lead to fracture of the cracked area were obtained.
Study of the physicochemical characteristics of mesoporous carbons obtained by using SBA-16 mesoporous silica as template
Authors: Hoyos Leidy , Mesa Mónica
Published: February 2024

The objective of this work is to determine the porous and chemical characteristics of mesoporous carbons synthesized by using SBA-16 mesoporous silica as template. The evaluation of the ability of adsorbing dyes contributes to the physicochemical characterization of these materials. Two SBA-16 mesoporous silica with different porous characteristics are used as templates and sucrose and ethylene are the sucrose sources. The pore size and volume of the mesoporous carbons can be modulated by the selection of the template. It does not occur for the chemical properties.

Authors: Kalenatic Dusko , Mancera Méndez Luz Helena , Moreno Valbuena Karol Viviana , González Rodríguez Leonardo José
Published: February 2024

This paper presents a logistics planning methodology which integrates four conceptual tools: management services, logistics, project management and system dynamics. This methodology is used to make an integral analysis of the activities carried out by service provider companies across the logistics cycle. The process of service is understood as a succession of projects, which for each activity analyzes the controllable and uncontrollable variables, the renewable and nonrenewable resources and their interactions from a systems perspective. This integration is supported in the system dynamics as a tool for quantitative analysis. The methodology supports the decision-making at the strategic, tactical and operational level to improve coordination between the activities and resource allocation by reducing delays and improving customer perception about quality of service.
Preparation and characterization of Mg-modified zirconias as catalysts for the direct synthesis of dimethyl carbonate (DMC)
Authors: Orrego Romero Andrés , Montes de Correa Consuelo , Bustamante Lodoño Felipe
Published: February 2024

In this work sol-gel zirconia was prepared using H2SO4, HNO3 or HCl as hydrolysis catalysts. Basic and acid sites of synthesized zirconia materials were characterized by XRD, BET, FTIR, CO2- TPD and NH3-TPD. FTIR spectra and TGA confirmed the presence of sulfate in the structure of samples prepared with H2SO4 as hydrolysis catalyst. Different molar ratios of Mg were incorporated by co-gellation on selected zirconia materials in order to improve their basic properties. Mg loading was determined by elemental analysis. The resulting materials were tested for the direct synthesis of dimethyl carbonate (DMC) from methanol and CO2. The addition of Mg to zirconia samples prepared with HCl as hydrolysis catalyst increased their CO2adsorption capacity between 100 and 200°C. However, methanol conversions on these samples were lower than over unmodified zirconia samples.
Surface characterization of borated γ-alumina by using proton affinity distributions

Published: February 2024

Borated aluminas with different boria contents (2, 3, 5 and 8 wt.% B2O3) were prepared to be used as supports for hydrotreating CoMo catalysts. The borated aluminas were characterized by proton affinity distributions (PAD) to obtain information about changes caused by boron introduction in the surface hydroxyl groups. The later being the sites by means of Mo and Co are anchored to the support. Two new peaks, which cannot be attributed to alumina hydroxyl groups, were found in the PAD profiles of borated aluminas. These two new peaks increased with increasing boria loading, even, in the PAD profile of the alumina with 8 wt.% B2O3 almost no other peaks were present. By comparing PAD profiles with FT-IR spectra of both the OH stretching (3900-3400 cm-1) and the skeletal (under 2000 cm-1) regions, it was possible to assign these new peaks to hydroxyls linked to trigonal and tetrahedral borated species, respectively. Thus, it could be inferred that boria OH groupsprogressively replaced alumina ones with increasing boria content forming a cover layer. Trigonal borated species were always predominant, however the relative population of tetrahedral species increased with increasing boria content.

Authors: Duque Carlos , Montes Consuelo , Bustamante Felipe , Ortiz Alejandro
Published: February 2024

This work aimed at simulating two processes for capturing sulfur dioxide from exhaust gases of wet clinker processes. The goal is to present a guide to cement manufacturers when selecting the most appropriate technology for wet processes in order to comply with environmental regulations. The available commercial technologies chosen for desulfurization process were: wet limestone and wet Cement Kiln Dust (CKD) removal processes. A commercial simulator (Aspen Plus v.2006.5) was used. The absorption tower -considered the core of the process- was simulated with an Aspen RadFrac model combined with Aspen RateSep calculations to provide better and more accurate simulation results than a simulation with the traditional equilibrium approach. This combination also allows better estimates for equipment sizing. The convergence issues, both for the absorption of sulfur dioxide and the overall process, were solved using Aspen Plus tools.
Dynamics of the primary production of phytoplankton in tropical lake through the flood pulse
Authors: Montoya Yimmy , Aguirre Néstor
Published: February 2024

Compared to aquatic ecosystems in temperate zones, tropical flood plain lake systems are highly complex, and poorly understood. This work evaluated the variation of primary production and phytoplankton biomass in one station in Escobillitas swamp in the complex of Ayapel system, located in northern Colombia. Primary production presented variation in relation to the flood pulse, as it ranged from 0 (high water ascent in 2007) and 191.6 mgC m-2 d-1 (high water on the decline in 2007) with an average value of 108.6 mgC m-2 d-1. We found the highest gross primary production in high water falling, a condition accompanied by increased algal biomass photosynthetic efficiency, reduction low rates in respiration and the P / B and P / R. ratios. Between consecutive hydrological cycles variations in the patterns of primary production the high water rising in 2006 had a low biomass, high PPB, with the highest photosynthetic efficiency, and low respiration rates; in contrast, for the same period of the hydrological flood pulse in 2007, an increase in biomass and reducing of PPB, photosynthetic efficiency, P / B ratio and respiration were observed. The water system changed between euproductive and oligoproductive, which indicates a high trophic dynamics.

Authors: Serna Montoya Edgar
Published: February 2024

Many papers describe ontological designs but few explain how to design ontology. Moreover, very few focus on applying knowledge management techniques for software maintenance. This paper provides an analysis of several of the ontology’s proposed to address this need, in order that some of their ideas can help software development organizations in similar work, and describes a methodology for structuring an ontology that, besides the area of software maintenance, can be applied in other areas of knowledge.
