Analysis of the marginal abatement cost curve for ammonia emissions: addressing farm system heterogeneity
Authors: Ogunpaimo O.R. , Buckley C. , Hynes S. , O’Neill S.
Published: December 2024

Agriculture is responsible for 99.4% of ammonia (NH3) emissions in the Republic of Ireland and the country has failed to comply with limits set down by the European Union National Emissions Ceiling Directive (NECD) for 9 of the last 11 reporting years. Hence, there exists an urgent need to reduce NH3 emissions to control air pollution and moderate other related environmental and health hazards. This study carries out farm-level marginal abatement cost curve analysis across different farm typologies in the Republic of Ireland. The study also addresses the interactions amongst the considered abatement options and explores the presence of farm system heterogeneity. This allows an assessment as to whether it is sub-optimal to adopt a mitigation measure across different farm systems. Findings indicate that the measures examined in this study are effective in abating NH3 emissions at varying levels across the different farm typologies. Ammonia mitigation measures such as liming, switching to protected urea and a crude protein reduction in livestock diets were primarily cost-saving while the increased clover measure moved between cost-saving and cost-positive depending on the farm system type. The presence of heterogeneity across the farm typologies was generally supported in this study, highlighting that optimal policy design should be tailored to reflect farms’ characteristics. Furthermore, a lower abatement potential was reported for the combined implementation of selected mitigation measures compared to the sum of individual measures due to interaction effects.
Les perceptions des professionnels(les) de la gestion des ressources humaines à l’égard de l’usage de l’intelligence artificielle pour l’embauche d’un personnel diversifié
Authors: Deschênes Andrée-Anne , Beaudry Catherine , Sanni Yaya Mouhamadou
Published: December 2024

Le recours aux systèmes d’intelligence artificielle (IA) dans les pratiques de recrutement et de sélection du personnel s’avère un moyen innovant pour favoriser l’embauche inclusive d’un personnel diversifié. L’IA permettrait aux organisations de s’affranchir de certains biais inconscients qui sont susceptibles de teinter le processus de dotation, puisqu’elle repose sur une prise de décision qui se veut objective. Cet article s’intéresse à la perception des professionnels(les) de la gestion des ressources humaines (PGRH) quant à l’utilisation des systèmes d’IA et aux pratiques inclusives d’embauche du personnel sous la lentille de la gestion de l’équité, de la diversité et de l’inclusion dans les milieux de travail. Prenant appui sur des données qualitatives (17 participants(es) à trois groupes de discussion), l’article s’appuie sur une recherche menée auprès de PGRH au Québec. Les résultats montrent que plusieurs barrières au recrutement et à la sélection d’un personnel diversifié persistent au sein des organisations, parmi lesquelles se trouvent la prédominance de genre dans certains secteurs et l’absence d’une culture organisationnelle inclusive. Si l’IA peut s’avérer utile et facilitante dans le processus, notamment pour le traitement d’un grand volume de candidatures, le jugement professionnel demeure préconisé pour tendre vers un processus d’embauche inclusif et la diversification de la main-d’oeuvre. L’utilisation encore timide des systèmes d’IA repose sur des craintes et sur une certaine méfiance à son égard, et des biais qu’elle est aussi susceptible d’engendrer. Les résultats confirment donc l’écart entre la place occupée par les outils de l’IA dans les pratiques de GRH et l’état des connaissances scientifiques.
Prendre soin et apprendre à dire non : les apports de la permaculture pour repenser la participation aux décisions en économie sociale et solidaire
Authors: Michaud Valérie , Pinard-L'Abbée Mylène
Published: December 2024

Étant donné leurs valeurs, mission et gouvernance démocratique, les organisations de l’économie sociale et solidaire sont des milieux suscitant naturellement l’engagement et la participation. Or, la participation est paradoxale : malgré ses nombreux avantages (pour l’individu, l’organisation, la société), elle peut parfois être forcée et générer des effets moins positifs, entre autres, du stress et de l’épuisement. De récents travaux témoignent de problèmes croissants d’épuisement professionnel, de souffrance et de précarité en économie sociale et solidaire, de surcroît en contexte de besoins énormes et de ressources (humaines, financières) limitées. Comment, dès lors, s’assurer que ces organisations démocratiques soutiennent la participation aux décisions d'une manière qui nourrisse, n’épuise pas et, un pas plus loin, régénère les personnes? Nous suggérons que la permaculture pourrait offrir des pistes de réponse à cette question. À partir des vignettes d’observations issues d’une recherche-action menée auprès d’une coopérative de solidarité, nous montrons comment la mobilisation des règles d’éthique et principes de la permaculture génère de nouvelles perspectives pour réfléchir au comment et au pourquoi de la participation à différentes décisions. L’article permet de suivre la coopérative dans cette expérimentation et de voir comment elle en vient à dire non à un projet qui s’inscrit pourtant dans sa mission, tout en y contribuant, en prenant en compte le bien-être de l’organisation ET des personnes. Trois apports potentiels de la permaculture sont dégagés : 1) l'importance de prendre soin des humains; 2) les renoncements conscients; 3) la « communification » du travail et la création de sens.

Robust depth map refining using color image
Authors: Kondratyev Sergey B. , Antoshchuk Svitlana G. , Hodovychenko Mykola A. , Ustenko Serhii A.
Published: December 2024

Depth maps are essential for various applications, providing spatial information about object arrangement in a scene. They play
a crucial role in fields such as computer vision, robotics, augmented and virtual reality, autonomous systems, and medical imaging.
However, generating accurate, high-quality depth maps is challenging due to issues like texture-copying artifacts, edge leakage, and
depth edge distortion. This study introduces a novel method for refining depth maps by integrating information from color images,
combining structural and statistical techniques for superior results. The proposed approach employs a structural method to calculate
affinities within a regularization framework, utilizing minimum spanning trees (MST) and minimum spanning forests (MSF). Superpixel segmentation is used to prevent MST construction across depth edges, addressing edge-leaking artifacts while preserving
details. An edge inconsistency measurement model further reduces texture-copying artifacts. Additionally, an adaptive regularization
window dynamically adjusts its bandwidth based on local depth variations, enabling effective handling of noise and maintaining
sharp depth edges. Experimental evaluations across multiple datasets show the method's robustness and accuracy. It consistently
achieves the lowest mean absolute deviation (MAD) compared to existing techniques across various upsampling factors, including
2×, 4×, 8×, and 16×. Visual assessments confirm its ability to produce depth maps free of texture-copying artifacts and blurred edges,
yielding results closest to ground truth. Computational efficiency is ensured through a divide-and-conquer algorithm for spanning
tree computations, reducing complexity while maintaining precision. This research underscores the importance of combining
structural and statistical information in depth map refinement. By overcoming the limitations of existing methods, the proposed
approach provides a practical solution for improving depth maps in applications requiring high precision and efficiency, such as
robotics, virtual reality, and autonomous systems. Future work will focus on real-time applications and integration with advanced
depth-sensing technologies.

Published: December 2024

A ceramic compound was prepared by mixing calcium carbonate in a mole ratio to nanoscale titanium dioxide powder using the method of manufacturing powders, in addition to mixing and grinding for long hours up to 72 hours in the presence of non-ionic water. After which the powder was extracted and then it was dried at a temperature of 100 oC for 4 hours, and then it was treated at 800 oC in a convection oven at 10 oC of heat for every 2 minutes. An X-ray diffraction test of the ceramic powder was performed before adding the synthesized bone protein that was prepared from cow bones. Scanning electron microscopy and energy dispersion spectrometry were also performed before and after adding the BMP. The results of the examination showed a big difference in the properties of the compound in terms of the atomic structure, as new compounds of bone components were introduced into the atomic structure, and the results were interpreted through the practical intensity of examining the body fluid-like solution (SBF).
Evaluation of cellulase effect on the refining process of softwood bleached kraft pulp
Authors: Park Sung Gyu , Tak Ji Hyun , Lee Ji Young , Shin Kyoung Sik , Park Se Il
Published: December 2024

As interest in the use of eco-friendly enzymes increases in the paper industry, an energy-intensive industry, the development of a wide range of enzyme application technologies is required. This study evaluated the effects of cellulase on the refining efficiency, fiber properties, and sheet strength of softwood bleached kraft pulp (Sw-BKP). The pulp was enzyme-dosed with cellulase for 6 h and refined using a laboratory beater for 15 min. The freeness and physical properties of the Sw-BKP fibers were analyzed. The pulp freeness decreased linearly as the refining time and enzyme dosage increased, indicating that the cellulase promotes refining efficiency by inducing fiber shortening and internal fibrillation during refining. Handsheets were prepared from 15-min refined enzyme-dosed and non-enzyme-dosed Sw-BKP. The strengths of the enzyme-dosed handsheets were lower than those of the non-enzyme-dosed handsheets because fiber shortening due to the cellulase activity was dominant during the refining. Therefore, cellulase effectively reduces refining energy consumption. However, it is essential to determine the correct enzyme dosage and refining time to balance the desired refining energy reduction with the resulting paper strength.
CONFUSION OF SUBJECTIVITY: BETWEEN TRAUMA AND (OVER)PASSION
Authors: KOZACHYNSKA Viktoriia
Published: December 2024

Purpose is to discover the continuity of explications of subjectivity in the moduses of the structure of affectedness as constitutive for its heterogeneous nature. Theoretical and methodological basis are the principles of the phenomenological description of subjective experience, the means of historical and philosophical analysis, hermeneutical methods of understanding and interpretation. Methodological background is the idea of subjectivity as transcendent in immanent, which is a framework for the non-classical image of a man. The logic of the work is motivated by a shift from a situation of passivity to subjectivity, which is affected by the own history and gains the constitutive experience of trauma, hetero-(auto)affectedness or (over)passion. In the newest French phenomenological and (post)phenomenological studies vulnerable subjectivity, constituting in the moduses of structure of affectedness, is formed due to the exceptional experience of trauma, hetero-(auto)affectedness or (over)passion, which irreversibly (re)creates subjectivity “in spite of itself”. That is, the formation of subjectivity is disturbed by an exceptional experience, which, irrevocably denying the foundations of the subject’s existence, constitutes him “against himself”.

If the heteroaffected subjectivity of J. Lacan and E. Levinas is a passiveness principally, since the traumatic experience of passive “patience”, destroying the narcissistic ideas of subject about yourself, constitutes the subject “against his will”, then in (post)phenomenological research (M. Henri – A. Maldine) explicated between a trauma and an (over)passion subjectivity is formed in the structures of auto-affectedness, which connects passive acceptance of affect with active responsiveness – the response to affect. The continuity of explications of subjectivity in the moduses of the structure of affectedness – from the situation of passiveness to subjectivity, which gains the experience of trauma, hetero-(auto)affectedness or (over)passion, justifies the constitutiveness of affectedness for the heterogeneous nature of subjectivity.
EXPERIENCE OF BEING: ORIGIN, PARADIGMATIC POTENTIAL, WAYS AND MEANS OF CULTURAL RECEPTION
Authors: SOLONKO Leonid
Published: December 2024

The article is devoted to the experience of being; it suggests that the experience of being is the basis of human subjectivity and is responsible for ensuring the connection between man and the universe. Intuitions born in the process of being experience are used by a person to solve existential problems. Being experience in its immediacy was revealed to man in the epoch of transition from primitive communal relations to class society. The discursive comprehension of the being experience undertaken by ancient philosophy led to the development of the concept of being.

Similarities in the descriptions of basis experience found in the texts of philosophers and religious mystics across diverse traditions, suggests the presence of a fundamental, invariant experience of being at the core of human spirituality. While interpreted differently in philosophical and religious contexts, this experience serves as the foundation for all conceptions of being, At the intersection of the intuitive experience of being and its discursive comprehension, the cultural category of being is formed.

The second part of the article is devoted to the analysis of the main mechanisms of being experience, which are responsible for the unfolding of the space of human activity and the experience of unity between man and the world. Particular attention is paid to the minimal phenomenal experience, and the possibility of identity between the minimal phenomenal experience and the being experience is considered. This idea is supported by Thomas Metzinger's research on minimal phenomenal experience (MPE).

Ultimately, it is proved that the experience of being is the experience of direct unity between the individual and being. This feature allows us to realise our identity with the world and participate in the self-actualisation of being.
ALIENATION OF RATIONALITY: THREATS, CHALLENGES AND THINKING POSTHUMANISM
Authors: VYSHYNSKYI Sviatoslav
Published: December 2024

The article is devoted to the problem of artificial intelligence and the challenges of “smart technologies”, which threaten the autonomy of human mind and the existence of human itself. The author states the crisis situation of contemporary culture, the existential fatigue of humanity, which manifests itself in the intention to delegate one’s own subjectivity, will and rationality to external actors – namely the Internet, artificial intelligence, and robotics. The article discovers the alienation of the fundamental quality of a thinking person – intelligence – and the threat of human enslavement in the world of the near future, governed by autonomous technologies. In addition to delegating rationality to machines, there is also a tendency to transfer goal-setting to “intelligent technology”, which is gradually endowed with the ability for self-learning and self-programming, and therefore may not align its tasks with human intentions. This problem is traced back to the origins of philosophical thinking and the earliest mentions of artificial beings in mythology, theology, fiction and scientific theory, that proves eternal human strife for creation and replication of human traces in natural environment. Humanization and rationalization of outer world thus is thought as an integral feature of human activity, but it also means constant and continuing alienation of human mind due to its openness and incompleteness, that puts mankind at risk – yet therefore defines humanity as a “risky” way of being. The author considers a scenario of the doubling of reality, in which digital algorithms, computer programmes and robotics may conquer, supplant or replace the world of nature and the human world, bypassing the latter as a less effective evolutionary step. In contrast to this, the author raises the question of what is mind, what is thinking and what is a human being – and whether consciousness, reduced to corporeality, sensuality or rationality, can serve as a model for reproduction. And whether a person is capable of creating a new life without love?
THE PHILOSOPHICAL-ANTHROPOLOGICAL IDEA OF THE WORLD AS A THEORETICAL PROGRAM: THE BEING OF THE COGNITIVE RELATION
Authors: SHALASHENKO Hennadii
Published: December 2024

The article examines some features of the philosophical-anthropological approach to the cognitive activity of a person, which is presented in it primarily as the «of-being-relationship» of a person to his world. The peculiarities of this approach to cognition are primarily due to the following. All contemporary philosophical trends, such as the transcendental-critical approach, evolutionary theory, existentialism, or various representatives of the linguistic turn, always come from the (cognitive) achievements of culture (intentional, intersubjectively constituted, immersed in the specifics of the subjectivity of consciousness, language, etc. ) and from there they try to investigate the factors enabling the subject's achievements; or, like the evolutionary theory, ultimately level out the essential difference in the principle of organization of human life, limiting it to the adaptive self-preservation of the organism. The philosophical-anthropological approach is based on the laws of the organic as a prerequisite for all cultural formations, from the vital process, and precisely from its fateful breakthrough for the human figure, from which it tries to derive the cognitive relationship as one of the mediators, which contributes to overcoming this gap and restoring the vital cycle in the human world. Accordingly, the cognitive relationship acts as a relationship that emerges in the very being, woven into the specific functionality of a living being, a person. And reflexively decisive here is not "exclusively" the internal status of the subject-object-splitting of the fact of knowledge, but its, so to speak, fully cognitively capable presence as an essential relation. The being of cognition does not arise, it only "does not disappear"; it "accompanies" the entire process of anthropogenesis, during which only an increase in the intensity of the unity of being is observed. As a conclusion, it would be appropriate to demand: scientific thinking, by its type of organization and objective intent, must resort to methodological and conceptual self-criticism, and pay attention precisely to the substantive importance of its anthropological foundations, that is, not simply to certain personal or community circumstances in which a scientist or the scientific community work, and on the anthropic principle as an internal principle, on the basis of which the constitutive interpretation of knowledge as such takes place.
ESTIMATING THE LEVEL OF TROPOSPHERIC ABSORPTION AT MICROWAVE FREQUENCIES AND OPERATIONAL PARAMETERS OF PERTINENT AERONOMIC AND RADIO ASTRONOMICAL INSTRUMENTS IN THE "MAXIMUM CONFIDENCE" TECHNIQUE

Subject and Purpose. The work has been aimed at the development and practical implementation of a new method for processing the results of aeronomic and radio astronomical observations that are performed with the help of a total-power radiometer for a variety of elevation angles of the objects. The method proposed makes it possible evaluating the absorption coefficient in the troposphere and current basic parameters of the measuring system. The subject of research is the tropospheric zenith opacity , the scattering coefficient of the antenna system, and noise temperature of the radio receiver together with the antenna.
Methods and Methodology. The method is based on a new approach to mathematical processing of the observational results. In contrast to the widely used dual-parameter least squares method, we propose to vary one of the parameters, while determining its most probable value as such corresponding to minimal mean square deviations as functions of the parameter’s value. The estimates obtained within this procedure are regarded as the most probable values of the atmospheric absorption constant (troposphere opacity in the zenith direction), the scattering coefficient of the antenna system, and the noise temperature of the radio receiver (together with the antenna). The technique proposed has been named the "maximum confidence" method.
Results. The method developed was first demonstrated and verified on a mathematical model. The same way the experimental data obtained in the 3-mm range of wavelengths, with different receivers and meteorological circumstances were processed. The effectiveness of the "maximum confidence" method proposed by the authors has been proven.
Conclusions. A new method of processing the data of aeronomic observations allows us to increase the accuracy of measurements of the tropospheric zenith opacity. In addition, it gives possibility to determine the scattering coefficient of the antenna and to monitor the noise temperature of the radio receiver. The latter has its own importance as a method of determining the parameters of the receiving system during real operation rather than separately on specialized measuring stands.

Published: December 2024

Thermodynamic response functions, namely, the isothermal compressibility, the thermal pressure coefficient, and the thermal expansion coefficient, are calculated for a many-particle system interacting through a modified Morse potential. These calculations are based on an equation of state previously derived for a cell fluid model in the grand canonical ensemble. The calculated quantities are presented graphically as functions of the density and the effective chemical potential.
Las narrativas del arte en Colombia. Construcción y uso de un concepto historiográfico, 1850-1930
Authors: Cruz Juan Pablo
Published: December 2024

Objetivo: evaluar, en términos de discurso, las reflexiones desarrolladas por José Manuel Groot, Alberto Urdaneta y Roberto Pizano en torno a la producción visual colonial, con el fin de rastrear los orígenes del concepto de arte aplicado a la producción visual del periodo colonial y utilizado hoy como parte de la reflexión historiográfica. Metodología: Lo anterior se realiza siguiendo los planteamientos hechos por la llamada historia conceptual, a partir de la cual se asume que la idea de arte asociada a la producción visual colonial se presenta como un constructo propio del siglo XIX, cuyo resultado fue la subversión del lugar de producción de la pintura de los siglos XVI y XVII. Originalidad: Este estudio se distancia de quienes aún hoy asumen la producción visual de los siglos XVI y XVII como producto artístico, legible a la luz del aparataje institucionalizado por el academicismo y las reflexiones estéticas vinculadas a la filosofía y la historia del arte propias de los siglos XVIII y XIX. En esta medida, introduce una reflexión útil en relación con la lectura y la correcta comprensión, no solo del llamado “arte colonial”, sino también de los procesos de construcción y resignificación del pasado llevados a cabo en el siglo xix en Colombia. Conclusiones: la producción visual colonial, concebida originalmente como fabricación mecánica, terminó convertida, gracias a la mirada de hombres como Groot, Urdaneta y Pizano, en un producto estético, un arte que, bajo la mirada del siglo XIX, representaba parte de la civilización heredada del mundo hispánico que debía hacer parte del ser cultural de la nación. Bajo este supuesto, se plantea la necesidad de reevaluar los métodos utilizados por la historia del arte para observar los objetos del pasado, acercando sus metodologías a las de la historia conceptual o el constructivismo histórico empleadas en la historiografía tradicional desde la década de 1970.

El libro Soberanías enfrentadas. Transiciones políticas del municipio de Quito entre 1813 y 1830, del profesor Santiago Cabrera Hanna, producto de su tesis de doctorado en Historia, indaga acerca del tema de las “soberanías enfrentadas” en los territorios que hacían parte del llamado Reino de Quito durante el proceso revolucionario e independentista, que aquí va desde los cambios de la monarquía española (1813-1822) a la formación de los Estados nacionales colombiano (1822-1830) y ecuatoriano (1830). A través de esta obra, el autor busca mostrar cuáles eran las entidades políticas que reclamaban la soberanía y los conflictos entre estas; para ello, analiza los cambios que se fueron dando en la coyuntura de dicho periodo, en la organización de la representación política local, provincial, departamental y nacional, y sus consecuencias.

Sobre la disfluencia textual. Un estudio para un diálogo en ciernes
Authors: Rivero García Marisol , Garone Gravier Marina , Martínez Marroquín Rebeca
Published: December 2024

Esta investigación se centra en analizar las fuentes disfluentes en el diseño, específicamente desde la perspectiva tipográfica. El objetivo es confirmar la validez de investigaciones previas sobre disfluencia tipográfica realizadas en países de habla inglesa (Eitel, Kühl, Scheiter y Gerjets, 2014; Lehmann, Goussios y Seufert, 2016; Thompson e Ince, 2013, por mencionar solo algunos ejemplos), aplicándolas al contexto sociocultural de Ciudad de México y Madrid. La hipótesis plantea que la legibilidad de una fuente tiene una influencia determinante en la recepción, retención y recuerdo de un mensaje. A través de experimentos cuantificables, se busca comprobar esta hipótesis, argumentando a favor del uso de fuentes menos legibles como herramienta consciente para generar un impacto cognitivo en el lector y mejorar la memorización del mensaje. Con este estudio podemos decir más claramente que las variables de disfluencia pueden afectar de manera variable a distintas poblaciones, dependiendo de su marco sociocultural o experiencias vivenciales en momentos y lugares geográficos específicos.

Published: December 2024

Los árboles mentales son un método de graficación del proceso de investigación y creación en diseño que esta consignado en el libro: Árboles Mentales, método de graficación del pensamiento complejo (Arenas, 2019). El presente trabajo explica la implementación pedagógica en el aula de los árboles mentales, y describe las implicaciones didácticas en la construcción de estos en cada uno de sus pasos, que van desde la investigación compleja de cualquier tema hasta la concreción del proceso creativo a manera de producto, servicio o experiencia de diseño. Los pasos metodológicos son seis: pregunta movilizadora, nodos de investigación, cruces para la creación, terminales como determinantes de diseño, rutas de definición e intervención de diseño. Este trabajo explica los alcances del proceso de enseñanza y aprendizaje en cada uno de sus pasos, entendiendo que lo importante es enseñar con la emoción de quien aprende. Se realizó una prueba piloto en la Universidad Nacional de Colombia (Sede Palmira) que consistió en recoger 15 árboles mentales realizados por estudiantes de la carrera de Diseño Industrial. Adicionalmente, se recogieron testimonios, en formato video, que giraron en torno a tres preguntas relacionadas con el proceso: ¿cuál es la relevancia de la implementación metodología de los árboles mentales a nivel cognitivo?, ¿qué dificultades y beneficios afrontó en la implementación metodología de los árboles mentales? y ¿cuál es la importancia de los árboles mentales para la creación de productos o servicios de diseño?
Improvement of growth and productivity in potato (Solanum tuberosum L.) crop by using biostimulants
Authors: Medina Avendaño Jenifer Dayanne , Pinzón-Sandoval Elberth Hernando , Torres-Hernández David Fernando
Published: December 2024

In Colombia, potato cultivation has significant social and economic importance for the population; however, rising input costs and low yields have led to a decline in the areas planted in the country. Biostimulants are substances or microorganisms that can enhance yield by improving the physiological processes of the plants. In Colombia, there are few studies evaluating their efficiency on potato productivity. Therefore, the aim of this research was to assess the effect of biostimulant applications on the growth and productivity of potato (Solanum tuberosum L.) variety ‘CIP 39’ under the conditions of the municipality of Paipa, Boyacá department. A completely randomized design was used, with four treatments corresponding to commercially registered biostimulants with an active hormonal ingredient, seaweed extract (SWE), or carboxylic acids, and a control. Variables such as fresh and dry weight of roots, shoots, and total biomass, leaf area index (LAI), yield by quality, and total yield were evaluated. The application of biostimulants resulted in improved physiological response of the plants. The SWE-based biostimulant exhibited a better balance in terms of fresh and dry biomass, as well as in LAI, leading to a significant increase in quality and yield. This indicates that the application of biostimulants can be an alternative to increase productivity in this production system.

Published: December 2024

The composition of the substrates in the vegetable seedbed phase is important for subsequent transplanting. The aim of this study was to evaluate the use of dry mass of the invasive aquatic plants Pistia stratiotes L. and Eichhornia crassipes (Mart.) Solms as a substrate mixed with Red Ferralitic soil for seedbeds of tomato and pepper. To plant tomato and pepper seeds, 300 alveoli were prepared with a mixture of Red Ferralitic soil with different proportions of dry mass of P. stratiotes (0.5% and 1.0%) and E. crassipes (2.0% and 4.0%). At 28 and 40 d after sowing, 30 seedlings per treatment were selected and the average length and diameter of the stem and primary root (cm) were measured. The Dickson quality index was determined in order to select the best treatment. The average stem length was greater in seedlings treated with P. stratiotes (0.5%) and E. crassipes (2.0%) and the diameter was greater in tomato seedlings treated with P. stratiotes (1.0%) and pepper seedlings with P. stratiotes (0.5%); this showed significant differences from the rest of the treatments. The maximum length and diameter of the primary root varied between treatments for both vegetables. The best treatments for the initial growth of tomato and pepper were those when Red Ferralitic soil and dry mass of P. stratiotes (0.5% and 1.0%) and E. crassipes (2.0%) were used as a mixed substrate.

Geo-electric techniques for estimating and mapping the electro-geohydraulic properties of the shallow aquifer within the Nsukka Formation in eastern Nigeria
Authors: Ibuot Johnson Cletus , Obiora Daniel , Ekpa Moses , Omeje Emmanuel
Published: December 2024

This study, employing Vertical Electrical Sounding (VES), was carried out within parts of Nsukka Formation located in southeastern Nigeria in order to determine the subsurface properties that aid in characterizing the subsurface. The study covers parts of Nsukka, Enugu Ezike, Obukpa and Eha Alumona in Enugu State, characterized by undulating terrain and a tropical climate with distinct wet and dry seasons. Twenty-one sounding data were acquired, and the measured data were quantitatively and qualitatively interpreted to determine the geoelectrical parameters. The interpreted resistivity curves revealed five geoelectric layers with different generic curve types. The secondary parameters estimated from modeled equations and their spatial distributions are displayed in the contour maps generated with Origin software. The estimated parameters - longitudinal conductance, transverse resistance, transverse resistivity, longitudinal resistivity, anisotropy, porosity, hydraulic conductivity, permeability, formation factor, and tortuosity-vary across the study area within the following ranges: 0.01 - 0.54, 373.90 - 11375.00, 109.56 - 5402.14, 108.72 - 4046.87, 1.01 - 1.88, 0.276 – 0.314, 0.187 – 3.509 m/day, 1.02E-5 - 9.32E-6 mD, 3.092 – 3.780, and 0.200 – 1.021, respectively. The variation of these parameters may be influenced by the heterogeneous nature of the subsurface. The regression analysis reveals the mutual relationships and correlation between the different parameters when plotted against each other. The results from this study are very promising, and demonstrate the efficacy of the geophysical approach in characterizing the subsurface for sustainable groundwater management and protection. The deployment of geo-electric indices in this study is to ensure adequate characterization of the subsurface.
Using potential field derivatives in the arctangent function to estimate the edges and relative depths of potential field sources

Several filtering methods have been introduced to estimate the edges of potential field sources. The selection of the appropriate technique depends on the type of data and the target. Among filtering techniques, phase-based filters are the most widely used methods due to the flexibility of their design, but they do not provide information on the source depth. In this study, some novel filtering approaches are proposed, highlighting the edge of adjacent sources with different intensities by initially removing the regional anomalies. These approaches generate low amplitude anomalies over the deep sources, and higher amplitude anomalies over the shallow sources, providing information on relative depths of the sources. To evaluate the designed approaches, synthetic and real data from the Finnmark area of North Norway were used. The results were compared with those obtained from other approaches. These results showed that the proposed approaches considerably simplify the interpretation of the anomaly maps with higher efficiency and broader interpretation scope than the classical techniques.

The paper deals in with the evidence probably related to a bronze workshop discovered along the Pannonian limes, at Dunaújváros (Hungary), an ancient Roman auxiliary fort with an associated civil settlement known as Intercisa. Such evidence raises the issue if the workshop was under the military command inside or outside the fort.

Rescue excavations were carried out in 1962 and 1967. In the 1970s, a late Roman building was discovered with 19 furnaces filled with glass, bronze and iron slag under it. Metal slag and half-melted bronze fragments were found in furnaces No. 7 and No. 10. The existence and density per square meter of such objects led to the interpretation of the site as a workshop district. The coin finds and the terra sigillata fragments allow the life of this district to be dated to the 2nd–3rd century AD.

Some years later other excavations were carried out on an area of 800 m2 about a 200 m distance from the workshop district. Among other finds a pit (1983/9) was brought to light in the area containing huge amounts of terra sigillata and pottery, as well as other objects, among them a bronze statuette of Mars Ultor also thrown in for waste disposal. This find comes as no surprise in military forts, but this iconography remains unique in Intercisa, while fragments probably belonging to bronze imperial statues come from the camp (Visy, 1983). Thanks to comparisons with other statuettes of the same kind the changing interpretation of such iconography in the provinces is discussed and its importance for the military fort analyzed as well.

The concept of waste to wealth which is the transformation of waste from an exhausted utility to a valuable commodity as a mechanism for effective solid waste management is yet to be properly utilized in Mubi north local government area of Adamawa state. The objectives included to identify the challenges facing waste market operation in Mubi North Local Government area. Questionnaires were distributed to 200 people. The numbers of respondents were evenly distributed on gender basis within the age group of 20-80 years. The result of the research revealed that 96% of the respondents are concerned about the volume of waste presently generated in the local government. 86% responded positively as they are supportive of waste recycled products especially for plastic/polythene products. 10% gave negative responds as they were of the opinion that recycle products may not be durable and efficient. 10% of the respondents are uncertain. 10% shows poor responds. 5% gave high negative responds. 95% indicate lack of sensitization and enlightenment on need for proper sorting before disposal. Participation in the waste market operation: 77% gave positive response, 10% gave negative responds and 13% of the respondents were uncertain. Those who responded saw the job as demanding, which can be attributed to the present perception of the job. Those who responded positively have been involved in the waste market operation indirectly as they have in so many occasions sold household recoverable waste in exchange for other useful items or money. This people would be encouraged more if government provides certain incentives necessary to make the market lucrative.

Chemical modification of coconut shell using acetic anhydride has been investigated. Batch mode experiments were carried out to study the effects of time, temperature and catalyst on extent of acetylation. The kinetic data obtained at different temperatures were analysed with pseudo first-order, second-order and intra-particle diffusion model. The experimental data fitted very well the pseudo first-order kinetic model. Thermodynamic models used enabled the evaluation of activation energy, heat of acetylation, critical temperature, critical degree of acetylation, heat capacity, entropy changes, Gibbs free energy and showed that under standard conditions that the acetylation of coconut shell occurs spontaneously. Chemical characterization by FTIR, X-ray diffraction (XRD) and Scanning electron microscope (SEM) showed clear evidence of acetylation. Swellability studies showed that the raw coconut shell had its swelling capacity reduced after treatment indicating a considerable increase in hydrophobicity, and thereby enhancing its potentials for use in oil spill remediation.

The results indicated that the study water was polluted and could only be suitable for drip and sprinkler irrigation if filtered at two levels: before and after storage to avoid blockage of emitters, since the water was highly turbid with high content of suspended particles. The physio-chemical parameters such as turbidity, Ph, conductivity and chlorine were within the World Health Organization standard for irrigation with wastewater. The trace metals such as copper, zinc, iron and manganese were below World Health Organization standard for irrigation with wastewater and also below the Environmental Protection Agency of Ghana standard. This indicates that the trace metals concentration in wastewater at Zagyuri has insignificant risk to soil and vegetable crops produced. Disc filtration can effectively reduce the concentration of suspended solids, colloidal matter, and certain dissolved constituents.

A window to new opportunities?

In this article we examine the present and future roles of archives and archivists in relation to contemporary institutional pressures to entrepreneurialise. We investigate them where they meet the public, where the information sector meets entertainment in a reading of the Swedish reality-TV show It’s in the Walls, where archives play a prominent role. We claim that the most likely archival entrepreneur would be a go-between, communicating the value of archives. In our exploration of what such go-between entrepreneurs might look like, we conceive of seven different possibly productive, possibly problematic, roles in which ALM-professionals, that is all who are working with the materials and matters of the institutions of Archives, Libraries and Museums could be cast. Focusing specifically on archival professionals, we name these, in the (entrepreneurial) spirit of a playful inquiry: The Entertainer, the Expert, the Explorer, the Emotion Facilitator, the Educator, The Evidence Provider, and the Knowledge Organiser. The TV show in our analysis serves as a window through which may be spotted new opportunities and we aim to contribute to a critical discussion of what the introduction of initiatives and discourses of entrepreneurship might do in, and to, the everyday lives and roles of ALM-professionals.
