Agroecological substantiation of technologies for growing grain crops in the conditions of the Southern Steppe of Ukraine
Authors: Drobitko Аntonina , Kachanova Tetiana
Published: January 2024

Agroecological substantiation of cereal crops cultivation technologies becomes especially relevant in conditions of insufficient moisture, as it requires sustainable and efficient agro-production systems that ensure high yields and preserve natural resources. The aim of the study is to determine the impact of nitrogen fertilisation on the growth and development of winter wheat in an arid climate. To achieve this goal, a field study was conducted at the fields of the Educational and Research Centre of Mykolaiv National Agrarian University to study mineral nutrition and the impact of different nitrogen rates on the structure and quality of winter wheat grain yield. The study found that increasing nitrogen fertiliser rates has a positive impact on crop growth and yield. The application of higher nitrogen rates, in particular N60 and N80 in spring fertilisation, increases plant height by 3.8 and 4.6 cm, respectively, compared to N30. In addition, a double increase in nitrogen fertiliser rates resulted in a 3.5% increase in the number of productive stems and a 13.6% increase in the weight of 1,000 seeds. Mineral fertilisers also had a significant impact on winter wheat yields, with Р30К30+N60 and Р30К30+N80 yielding 51.8 and 49.3 c/ha, respectively. The results of laboratory studies confirmed that nitrogen fertilizers in an increased amount lead to a decrease in the starch content in winter wheat grains, while simultaneously increasing the protein content. Correlation analysis showed a tendency to increase the yield of winter wheat with higher application of nitrogen fertilizers, however, in order to avoid deterioration of the quality of crop products, it is important to follow the recommendations. The practical significance of the obtained results lies in optimizing the cultivation of grain crops, as well as increasing their yield in conditions of limited water resources and the threat of drought

Al director de la escuela secundaria en el sistema educativo mexicano le corresponde organizar el funcionamiento del centro escolar para lograr los objetivos institucionales, articular la organización, la planificación, la gestión de los recursos, el seguimiento de las actividades educativas, las relaciones con la comunidad educativa, entre otras acciones. No obstante, en ocasiones, debido a la carga laboral las tareas administrativas se delegan en la figura del subdirector de gestión y las labores pedagógicas en la figura del subdirector académico. En este estudio se argumenta la necesidad de que el líder se implique en todas las actividades del equipo docente, para motivar y potenciar el trabajo colaborativo de su equipo; particularmente se propone la metodología de proyectos a través del enfoque STEAM (Ciencia, tecnología, ingeniería, artes y matemáticas).  El objetivo es analizar la influencia de este liderazgo directivo en el trabajo colaborativo desde la visión del equipo docente que participa en proyectos STEAM. La metodología en la que se fundamenta este estudio es de corte cuantitativo con un alcance descriptivo y con un diseño no experimental transaccional – descriptivo.
ROLE OF INTERPRETATIVE REMARKS IN CLINICAL BIOCHEMISTRY-A PERSPECTIVE OF MEDICAL BIOCHEMIST
Authors: KANDASWAMY SELVAKUMAR , MURALIDHARAN SUGANTHI , NATARAJAN MEDHAVI
Published: January 2024

It is a professional requirement for clinical biochemists to provide Interpretative Remarks (IR). Few clinical labs give any comments at all, and the majority of laboratories just employ pre-written remarks on the report. In addition to physicians, other medical professionals, and occasionally even patients themselves, seek laboratory experts for guidance on data interpretation. The quality of interpretative remarks is impacted by the unavailability of the patient's medical record, restricted communication with the doctors, and a lack of professional experience. The purpose of this paper is to highlight how crucial it is to provide interpretive commentary in the context of responsibility for medical biochemists. In a similar vein, this paper offers guidance to those who offer interpretations.

Published: January 2024

The study assesses the level of heavy metals in some aquatic insects, lethocerus species, and Hydrophilus piceus (Great silver water beetles) found in river Gashua.  The insects and soil samples found in the river were randomly collected, processed, and analysed for heavy metals using atomic absorption spectrophotometry (AAS).  There’s no significant difference in the soil samples and the aquatic insects: Lethocerus species and Hydrophilus picueus.  The results also showed that the range of the concentrations of heavy metals found in the three samples in the order of their abundance as Mn > Pb > Cu > Ni > Cd and 0.03-1.71mg/kg  > 0.03-1.15mg/kg  > 0.05-0.54 mg/kg >  0.05-0.28 mg/kg  > 0.05-0.28 mg/kg respectively.  The results were compared to acceptable levels set by the FAO/WHO to see if the heavy metal levels in the insects were safe.  Assessment of the heavy metals in the soil and aquatic insects gives an idea of how heavy metals are transferred within a food chain and shows the level of bioaccumulation of the metals in aquatic insects.  The implications of the selected heavy metals found in the area's soil and aquatic insects were identified and discussed.  Practices that will reduce heavy metal pollution rates are encouraged among the inhabitants.  It was recommended that assessing the heavy metals concentration in the soil and the aquatic insects should be a routine to prevent excessive accrual in the food chain.

Authors: Pasati Yohanes Dwi Penta
Published: January 2024

The purpose of this study is to comprehend the basic guidelines of priestly formation in which priesthood candidates purify their vocation motivation and align it with the priestly vision, which isbased on a theological vision of Christ as the High Priest. This theological vision of Christ as the High Priest is then elaborated specifically in a rule of life for the priesthood candidates. This rule of life is constructed based on six aspects of formation: personality, spirituality, community, intellectual, pastoral, and vocation. After interpreting the theological vision, the priesthood candidates are invited to develop their vocation together in a community of priesthood candidates where they are invited todevelop themselves together in various fields of skills. This is what is called managerial activity, which even in formation, the elements of management affect the lives of the priesthood candidates. Based on this, the priestly formation is based on a formation guideline contained in the Ratio FundamentalisInstitutionis Sacerdotalis formation document. The goal of priestly formation is for the candidates to realize their future identity as priests of Christ. Therefore, in order to achieve this goal, priesthood candidates engage themselves in various activities that lead to the goal of formation. In the management term, this cycle is referred to as management functions. The management function itself consists of planning, organizing, implementing, supervising, and evaluating.
Takut akan Tuhan sebagai Awal Kebijaksanaan
Authors: Bala Gabriel
Published: January 2024

True Christian leadership comes from the Lord Jesus Himself. In Jesus, a Christian leader will lead the people entrusted to him with values and virtues that come from God himself. One of those values and virtues is the "fear of the Lord". Proverbs itself says that the "fear of the Lord" is the beginning of wisdom (1:7). Wisdom itself is one of the virtues that a leader must possess. Thus, if one wants to be a wise leader, then there must be the "fear of the Lord" within him. With this "fear of the Lord", a Christian leader will try to involve God in every decision. He will think about whether his decisions are good for everyone or not. In this article, the author will explore the spirit of Christian leadership according to Proverbs 1:7. What kind of "fear of the Lord" is meant in this book and how to apply it in daily life, so that this "fear of the Lord" can also become the spirit and spirit of Christian leaders.

Authors: Orlando Gabriel , Senger Hermes , Naldi Murilo
Published: January 2024

Many applications, require finding a dataset’s k-Nearest Neighbors Graph (kNNG), crucial for many Machine Learning tasks like clustering and anomaly detection. However, its computation can be costly due to the complexity of finding all kNN for every data point. To address this issue, scalable approximated algorithms have been proposed to speed up the kNNG and maintain its quality. This paper presents an adaption of NNDescent using multi-GPU and an experimental comparison of distributed and parallel approximate kNNG algorithms in GPUs, assessing their scalability, computational cost, and solution quality. Our goal is to identify the most efficient method without significant accuracy loss, enabling faster techniques and handling large datasets.

Authors: Morais Caio Von Rondow , Penha Jeronimo , Nacif José A. , Ferreira Ricardo
Published: January 2024

Full-crossbar interconnections offer high parallel bandwidth, simple routing, and performance. However, their cost is prohibitive. Multistage networks have emerged as a cost-effective alternative, reducing the cost to O(n log(n)). This study addresses the challenges posed by large networks with 256 connections, where the configuration space expands exponentially. We present an approach that efficiently handles routing by reducing the extra stages. We reduce network cost by a factor of 2×. Our approach enables graph routing with up to 214 operators within the 256-connection multistage network, doubling performance compared to previous multistage CGRA frameworks.

Published: January 2024

The knapsack problem is a classic and fundamental optimisation problem that serves as a subproblem in various optimisation algorithms. Thus, it is of great importance that we manage to solve several instances of the knapsack problem in a fast and efficient way. In this work we present a parallel algorithm, based on dynamic programming, that can take advantage of parallelism as more knapsacks need to be solved. The algorithm makes use of fine-grained data parallelism and is easily mapped to GPU accelerators. Extensive experiments with diverse datasets demonstrate the superiority of the proposed algorithm, achieving relevant speedups compared to a serial algorithm.
Bwjoin: A Blockwise GPU-based Algorithm for Set Similarity Joins
Authors: Quirino Rafael D. , Quirino André M. , Ribeiro Leonardo A. , Martins Wellington S.
Published: January 2024

Set similarity joins play a pivotal role in diverse fields, ranging from modern database management systems to near-duplicate detection and even galaxy cluster analysis in cosmology. However, due to their quadratic nature, these operations have been associated with substantial computational costs. To tackle this challenge, parallel solutions have been developed in recent years, spanning algorithms for distributed and shared memory architectures, as well as massively parallel systems like GPU accelerators. In this paper, we propose a new GPU-based algorithm, using the prefix-filtering technique, that harnesses the power of blockwise parallelism, achieving better performance than its competitors, especially for high threshold similarity joins in big datasets.
Impact of a dynamic Allocation Policy for Resource and Job Management Systems in deadline-oriented Scenarios
Authors: Linnert Barry , De Rose Cesar Augusto F. , Heiss Hans-Ulrich
Published: January 2024

As High Performance Computing (HPC) becomes a tool used in many different workflows, Quality of Service (QoS) becomes increasingly important. In many cases, this includes the reliable execution of an HPC job and the generation of the results by a certain deadline. The Resource and Job Management System (RJMS or simply RMS) is responsible for receiving the job requests and executing the jobs with a deadline-oriented policy to support the workflows. In this paper, we evaluate how well static resource management policies cope with deadline constrained HPC jobs, and explore two variations of a dynamic policy in this context. Our preliminary results clearly show that a dynamic policy is needed to meet the requirements of a modern deadline-oriented RMS scenario.

Published: January 2024

Platform-aware programming is a usual practice of HPC performance engineering programmers that is becoming more challenging due to the increasing heterogeneity of parallel computing platforms. In this paper, it is proposed a structured approach to platform-aware programming based on three concepts: platform typing, multiple dispatch, and feature detection. It has been implemented and evaluated through a proof-of-concept prototype built in Julia. It is evidenced that structured platform-aware programming provides better modularity and ease of maintenance with minor performance overhead.

Kollektives Unrecht und individuelle Schuld
Authors: Beinder Tobias
Published: January 2024

In international criminal law, an individualistic narrative prevails. System injustice is attributed solely to the behavior of individuals. This is a useful fiction through which normative conflict management is to be made possible. It relies on the isolation of the individual perpetrator and thus - as in "normal" criminal law - on the individual attribution of the acts. What remains unconsidered in this technique of isolation is that the international offender acts in conformity within a collective context of action. The question arises as to what effect this collective dimension has on the guilt of the individual. Individual imputation seems too reductionist to address collective injustice. But how can we avoid the individual becoming a scapegoat for deeds that would be inconceivable without the collective background in the first place? This is also a question of distributive justice.

Published: January 2024

Příspěvek seznamuje s výsledky povrchového průzkumu a geodeticko-topografického zaměření zaniklé středověké vesnice Zábdiší (k. ú. Drozdov), která náležela roku 1336 k panství hradu Žebrák. Celkem bylo zjištěno a zdokumentováno 29 antropogenních tvarů reliéfu představujících relikty obytných a hospodářských staveb. Sídelní forma byla interpretována jako návesní s devíti až deseti usedlostmi. Nálezy pozdně středověké až raně novověké keramiky získané povrchovými sběry zpřesňují dobu založení a zániku vesnice v intervalu od konce 13. do počátku 16. století. Pozornost je věnována také širšímu zázemí vesnice (extravilán), kde pomocí dat leteckého laserového skenování (LiDAR) a pozemního ověření byly identifikovány pozůstatky plužin, úvozů a milířišť. Ves je studována v širším sídelním kontextu panství hradu Žebrák, přičemž byly nově upřesněny polohy dalších dvou zaniklých vsí.

Na českomoravském pomezí, na katastru obce Rohozná, se nachází reduta obdélníkového půdorysu s bastiony v rozích. Středem opevnění prochází cesta, která byla zjevně i důvodem výstavby opevnění a kterou tato fortifikace kontrolovala. V článku jsou prezentovány jednak dosud známé informace k lokalitě a jednak dosud nepublikované výsledky menšího archeologického výzkumu realizovaného roku 2008. Opevnění je zakresleno na Müllerově mapě Čech z roku 1720, a je zde označeno jako Alte Schanz. Na základě kontextu událostí v regionu je předložena hypotéza, že fortifikace byla vybudována císařskou armádou někdy v období od března 1645 do léta (respektive zimy) roku 1647, v reakci na přítomnost švédské posádky v nedaleké Jihlavě.
Slovenská literatúra a kultúra v českej publicistike Františka Votrubu (1909–1918)
Authors: Dana Hučková
Published: January 2024

Czech-Slovak reciprocity was an integral part of the personal life program of František Votruba (1880–1953), which began in his his early youth, when he decided to leave his native Bohemia and move to Slovakia for work. In 1902, he came to Ružomberok to participate in the the publication of the newspaper Slovenské listy, which the publisher Karol Salva published in 1897–1900 to promote Czech-Slovak reciprocity. In the middle of 1903, he accepted Milan Hodža’s offer to contribute to the the publication of the political newspaper Slovenský týždenník, newly founded by Hodža; he moved from Ružomberok to Budapest, where he lived until the beginning of 1911. He later joined of the “group of Pest residents”, which co-created a new form of Slovak politics and culture. Through Hodža, Votruba became acquainted with the Slovak agrarian movement. He identified with the opinion that support for the Slovak national program should be sought among the Slovak farmers; the Agrarian movement should support them by solving their economic and social problems. Votruba added to that principal program his own ideas: the farmers’ need for education and culture through popular and educational texts. From the end of the first decade of the 20th century until the war years, he published in Czech periodicals, informing the Czech public about Slovak political, economic, cultural and literary conditions; furthermore, he reminded Czech readers of the importance of Czech activities for the dynamism of Slovak life, suggesting tasks for Slovakia. His goal was to promote the efforts of the first and second generation of the Hlasist movement and their magazines Hlas, Slovenský obzor and Prúdy. His interpretation of the relationship between Slovaks and Czechs were creating a historical narrative and a myth.
L’universel en psychomécanique du langage
Authors: Xiong Peiyao
Published: January 2024

Le questionnement sur la notion d’universel et celle de commun concerne largement les recherches linguistiques, littéraires, géographiques et philosophiques ; néanmoins, la question se pose de savoir comment nous comprenons lesdites notions en psychomécanique du langage de Gustave Guillaume. Dans cette présente étude, nous allons accorder une attention toute particulière à la notion d’universel du point de vue psychosystématique : en premier lieu, nous étudierons les mouvements d’universalisation et ceux de singularisation que conçoivent les architectures de la langue française ; en second lieu, nous éluciderons la consubstantialité de l’universel et du singulier au prisme de la logique ainsi que de la philosophie ; en troisième lieu, nous chercherons à redéfinir, mutatis mutandis, l’universel et le singulier qu’impliquent les mouvements mentaux tout en profitant des principes Yin-Yang. Qui dit universel dit singulier, l’apport guillaumien desdites notions dans la psychomécanique du langage enrichit bel et bien les analyses sur nos mécanismes mentaux, ce qui nous permet d’observer, de manière cognitive, les mécanismes du langage dans leur profondeur.
Deleuze face à Platon. Usages stratégiques du commun et de l’universel
Authors: Piat Alexis
Published: January 2024

L’œuvre de Gilles Deleuze constitue l’une des tentatives les plus abouties pour penser hors de l’universalisme, au profit d’une définition de la philosophie comme effort de création. Pour autant, un tel effort ne cesse de rencontrer l’universel sur sa route : comme puissance de mise en mouvement de la pensée, comme condition du partage de celle-ci et comme exigence pour elle de s’appuyer sur une certaine objectivité. Cet article entend établir dans quelle mesure il est possible de faire fonds sur la critique deleuzienne de l’universalisme tout en dépassant ces difficultés. À cette fin, il s’attache notamment à l’étude d’exemples issus des œuvres de Platon, cible principale de la critique deleuzienne de l’universalisme.
Les politiques linguistiques et l’immigration au xxie siècle : langue commune ou langue universelle ?
Authors: Edeleva Yulia , Chateau-Smith Carmela
Published: January 2024

Pour les Nations Unies, la langue est un « Instrument de communication orale et écrite propre aux membres d’une même communauté linguistique », mais la migration modifie les communautés. En 1887, l’espéranto fut proposé comme langue internationale ; en 1940, une langue contrôlée, le BASIC, limitait l’anglais à un lexique de 850 mots. Dès 1960, on recherchait des universaux linguistiques. En 2009, on voyait les langues comme des systèmes adaptatifs complexes et on développait le système Facile à Lire et à Comprendre (FALC). En 2020, le Cadre européen commun de référence (CECR) pour les langues évolue pour intégrer ces développements, notamment l’accessibilité. Le rôle du CECR dans les instructions officielles concernant le niveau de langue à atteindre pour obtenir le statut de résident est étudié pour trois pays géographiquement et économiquement proches : l’Allemagne, la France et le Royaume-Uni. Adapter certains documents administratifs selon les critères du FALC pourrait étayer le développement linguistique des migrants apprenants.
Qu’y a-t-il de commun dans le concept de communication ? L’exemple des bulletins scolaires au sein des relations École-familles
Authors: Monin Isabelle
Published: January 2024

L’étymologie commune du verbe communiquer et du nom communication, issus du verbe latin communicare, illustre la polysémie du terme, qui peut signifier : « avoir part », « partager », « participer », « être en rapport mutuel, en communion avec quelqu’un », « transmettre », etc. En d’autres termes, cette origine indique que la communication est une action, celle d’informer, tout en prenant en compte son destinataire – ou sa cible, que l’on considère comme de connivence ou susceptible de le devenir. Cet article tentera de mettre en évidence ce que nous pourrions isoler de commun dans la communication, en prenant pour exemple le genre du bulletin scolaire et assimilés, genre de discours qui conjugue individu singulier, pluriel et systémique, sans pour autant s’affranchir de la notion de personne.
La fabrique du commun
Authors: Le Quéau Pierre
Published: January 2024

La contribution propose une réflexion sur le rapport entre le commun et l’universel à partir de la distinction opérée par Cornélius Castoriadis entre l’instituant et l’institué. Elle montrera la dynamique de cette activité instituante, en laquelle consiste finalement le commun, en s’appuyant sur le matériau d’une enquête en cours réalisée au sein d’ateliers autonomes implantés dans la région grenobloise. La pratique à l’œuvre dans ces ateliers participe à la refondation continue de l’universel.
