Development of Tools for Creating Parallel Data Mining Algorithms
Authors: Karshiyev Zaynidin  , Sattarov Mirzabek
Published: February 2024

The purpose of this work is to develop tools for building parallel data mining algorithms for execution in a distributed environment. A formal model of a data mining algorithm is proposed, characterized by a representation of the algorithm in the form of a set of independent operations that change the state of the knowledge model and structural blocks that allow modifying the structure of the algorithm, including for parallel execution. A method is proposed for creating parallel algorithms for data mining, in contrast to existing ones, using a decomposition of the algorithm into thread-safe functional blocks and allowing parallelization, both by changing the structure of the parallel algorithm and by configuring its execution. A methodology is proposed for parallelizing data mining algorithms, which differs from those known in that the proposed method of creating parallel data mining algorithms taking into account the characteristics of a distributed environment is applied to sequential analysis algorithms. To create parallel data mining algorithms, software templates built on the basis of a formal model and separating the implementation of the algorithm from distributed execution tools are proposed. A library of parallel data mining algorithms has been developed for execution in a distributed environment, including the proposed templates.

Published: February 2024

The Final Year Project Presentation or FYPP is an essential academic oral presentation for tertiary students across various university courses and fields. Despite its importance, there exists a notable lack of comprehensive understanding about the genre, particularly about the conclusion section. This study aimed to investigate engineering students' perception of the good characteristics of the conclusion section in FYPP. A questionnaire survey was administered to a sample of 33 engineering students, who identified the following features as important components of the conclusion section: a summary of the final year project, presentation of overall findings, references to previous research, discussion of issues related to the final year project, restatement of the objective/focus, specific results, interpretation of results, significance of the results, limitations, counter-arguments, and an explanation of the final year project. The study reveals that students are aware of the various elements that make up the conclusion section and suggests that this knowledge can help them improve their FYPPs. By better understanding the genre expectations and characteristics, engineering students can present their final year project findings more effectively and demonstrate their mastery of the discipline.

Understanding First Nations exposure and sensitivity to economic and ecological change in Canada
Authors: Natcher David , Ingram Shawn , Bogdan Ana-Maria , Rahman HM Tuihedur
Published: February 2024

First Nations in Canada engage in a form of mixed economic production that includes the complementary integration of subsistence (eg hunting, fishing, gathering, sharing) and wage-earning sectors. The flexibility of mixed economies has long enabled First Nations to optimise the use and allocation of household assets (eg time, labour, income) during times of economic and ecological change. In this study, we relied on the disaggregation of household (N=1268) data to measure the extent to which First Nations households in the Peace River region of British Columbia and Alberta engage in the mixed economy. We found that 24% (N=303) of First Nations households participate at an above average level in wage-earning and subsistence harvesting and are involved in relatively dense food sharing networks. These households are in the most optimal position to respond to economic or ecological changes by exploiting the range of household assets at their disposal. Conversely, 29% (N=368) of households participate in both wage-earning and subsistence harvesting at below average levels and are largely excluded from food sharing networks. These households may be most sensitive to even modest exposure. The results of this research offer a fine scale analysis of household characteristics that can be used by First Nations governments for targeted interventions to alleviate household exposure to economic and ecological change.

Host relationships and biological notes of Cassidinae beetles (Coleoptera, Chrysomelidae) in Qiannan Prefecture, Guizhou, China
Authors: Yang Chaokun , Liao Chengqing , Xu Jiasheng , Dai Xiaohua
Published: February 2024

The faunal composition, host relationships and biological information of the subfamily Cassidinae (Coleoptera, Chrysomelidae) remain poorly known in many Chinese regions. Based on the seven-year field survey, faunal composition and host associations of Cassidinae beetles were systematically compiled for Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. In particular, through direct field observations, detailed biological information, such as life history and behavioural features and host plants were first recorded for 56 species of Cassidinae beetles. We have tripled the number of Cassidinae species in Qiannan. Sixty-nine species of Cassidinae beetles belonging to 17 genera and eight tribes were identified, of which 38 species are newly recorded in Guizhou and 56 are newly recorded in Qiannan. The tribes Leptispini and Notosacanthini were newly recorded in Guizhou. The genera Thlaspidosoma Spaeth, Downesia Baly, Klitispa Uhmann, Platypria Guérin-Méneville, Leptispa Baly and Notosacantha Chevrolat were recorded in Guizhou for the first time. A total of 61 species, 37 genera and 17 families of host plants were collected. Lardizabalaceae and Araliaceae were new host plant families for Cassidinae worldwide. Quantitative food web analysis indicated that Cassidinae species in Qiannan mainly feed on Poaceae, Rosaceae, Convolvulaceae and Lamiaceae. Callispini and Leptispini only feed on monocots, Aspidimorphini, Basiprionotini, Cassidini and Notosacanthini only feed on dicots, while Hispini feed on both monocots and dicots. The feeding patterns and corresponding damage marks of Cassidinae were quite diverse. In addition, the pupal mine-making behaviour of Dactylispa excisa (Kraatz, 1879), D. similis Chen et T’an, 1985 and D. uhmanni Gressitt, 1950 are worth further study. Although preliminary, our field survey is an essential step in understanding Cassidinae behaviour and Cassidinae-plant interactions.
Points, trames, chemins. Sur les pas de rescapés arméniens du génocide de 1915
Authors: Kunth Anouche
Published: February 2024

Voir apparaître les traces de la persécution au cours de déplacements migratoires, c’est ce que propose cette étude de cas, fondée sur l’examen des trajectoires de migrants arméniens originaires de l’Empire ottoman, privés de leur nationalité par la Turquie kémaliste au début des années 1920, contraints à l’exil. Tournant le dos à un monde disparu, ils émigrent des ports de Méditerranée orientale vers une Europe occidentale en quête de main-d’œuvre, ou vers les Amériques. Ces départs, en raison des formalités qu’ils requièrent, ont conduit les réfugiés arméniens à faire des déclarations aux autorités dont il reste quelques mots dans une liste ou un formulaire. De sorte qu’une documentation administrative, conçue pour identifier les personnes et contrôler les passages aux frontières, en vient à délivrer des indices de la destruction génocidaire qui a frappé les Arméniens ottomans durant la Première Guerre mondiale. Le suivi des itinéraires agit donc comme le révélateur d’un passé violent et invite à une réflexion méthodologique sur l’emploi, par l’historien, de sources ordinaires sans rapport direct avec les persécutions dont il entend traiter.
Refaire famille en migration après la Shoah. Les Juifs polonais et les organisations internationales au sortir de la guerre
Authors: Chopard Thomas
Published: February 2024

Dans le sillage de la Seconde Guerre mondiale et de la Shoah, les survivants juifs de Pologne ont entamé une importante migration à travers l’Europe, passant notamment par les camps de personnes déplacées d’Allemagne, d’Autriche et d’Italie. À rebours d’un regard souvent de surplomb de ces populations juives en migration, cet article entend combiner différentes échelles – générale, collective et individuelle – en mobilisant les archives des organisations internationales et humanitaires supervisant ces migrations. En entreprenant de retracer l’évolution des individus, des groupes et des familles juives originaires de Lubartów, dans la région de Lublin, cet article étudie la façon dont les configurations familiales ont déterminé en partie les trajectoires migratoires. Mais aussi, en retour, comment la migration elle-même a marqué une évolution rapide des groupes familiaux en insistant sur quatre aspects : les retrouvailles avec les proches, la création de nouveaux liens, la natalité et la substitution à l’absence de famille d’autres formes de solidarité marquées notamment par le sionisme. Cette approche par différentes échelles permet notamment d’offrir un regard critique sur un certain nombre de phénomènes particulièrement valorisés par les travailleurs humanitaires de l’époque et souvent repris tels quels par l’historiographie.
Es spukt ! La spectralité théâtrale dans Carolus Stuardus (1663) d’Andreas Gryphius
Authors: Gabaude Florent
Published: February 2024

In diesem Artikel soll die Allgegenwart des Gespenstischen in Andreas Gryphius‘ Trauerspiel Carolus Stuardus herausgestellt und seine verschiedenen Aspekte untersucht werden, insbesondere die Erscheinungsform und die dramaturgische Funktionalität der Wiedergängerfiguren. Der Geist verhüllt sich mit Maske, um die Wahrheit der vergangenen und zukünftigen Geschichte sowie die Heuchelei und Eitelkeit der Menschen zu offenbaren. Hinter dem Rückgriff auf ein dem Zeitgeist entsprechendes Thema, das die Flugschriften-Literatur füllt, verbirgt sich auch die Angst vor den politischen Umwälzungen im Europa des 17. Jahrhunderts und vor der Revolte der Unterschicht. Unter Bezugnahme auf die von Derrida geprägte Definition wird zudem der Begriff der Spektralität auf eine metaphorische Ebene gehoben, um die memorialen Mechanismen historischer Kontinuität und Brüche zu beleuchten.

La Fontaine paresseux ? Formes et fonctions d’un lieu commun du discours critique ( xvii e - xix e siècle)
Authors: Fortin Damien
Published: February 2024

On le reconnaît volontiers, celui que la vulgate critique a baptisé du surnom condescendant de « Bonhomme » aurait été un paresseux. Voilà la légende tenace qui enveloppe la vie et l’œuvre de La Fontaine. Cette image sculptée par ses contemporains avant la publication de son œuvre et assumée par le poète dans ses vers, les biographes et les critiques la reprennent volontiers pour la présenter comme une clef de compréhension de l’homme et de l’écrivain. La présente contribution prend pour objet d’étude les discours critiques formulés et diffusés au cours des XVII e , XVIII e  et XIX e  siècles en vue de dégager les enjeux d’un lieu commun de la critique lafontainienne autour duquel s’articulent le récit d’une vie et la lecture d’une œuvre.
Les lieux de la paresse
Authors: Moreau Isabelle
Published: February 2024

La présente analyse propose de localiser les manifestations discursives concurrentes d’une paresse associée aux « ruelles » à partir d’une étude croisée de trois textes adressés au public des honnêtes gens – le Traité de la paresse de Courtin, les conversations « De l’oisiveté » et « De la paresse » de Madeleine de Scudéry, et le Temple de la paresse attribué à Pellisson. La mise en série des lieux de la paresse permet alors de faire émerger les enjeux sociaux et politiques que cristallise cette notion.
Reprise externe d’une PME : engagement social, sociétal et environnemental du repreneur comme facteurs de construction de sens en période post-reprise
Authors: Mouhli Karim , Mazari Lyes
Published: February 2024

La responsabilité sociétale des entreprises (RSE) et la reprise d’entreprise apparaissent comme deux défis majeurs auxquels sont confrontées les PME françaises (Mazari et al ., 2019), cet article suggère de s’intéresser aux pratiques de RSE initiées par les repreneurs externes de PME. Il propose d’explorer le potentiel d’un mode de management orienté RSE comme un facilitateur de construction de sens post-reprise. Plus précisément, nous cherchons à déterminer si l’introduction d’un mode de gestion RSE favorise la compréhension par les salariés du changement causé par l’arrivée d’un nouveau dirigeant, et si oui, par quels moyens. Les résultats mettent en évidence différents facteurs attachés à un engagement RSE du repreneur comme facilitateurs de la construction de sens autour de son projet par les salariés. À partir des facteurs informationnels, organisationnels et stratégiques mis au jour nous avons élaboré un modèle fondé sur le processus de sensemaking comme condition et soutien à l’émergence d’un nouveau système d’actions organisées.

Jacks Start Abroad
Authors: Gillman Sally A.
Published: February 2024

Jacks Start Abroad (JSA) students, from five different cohorts 2016-2019, traveled abroad on academic programs specifically designed for first-year students before beginning their first semester at South Dakota State University (SDSU). Students were assessed with the modified global perspectives inventory using a pre- and post-test model. In addition, the 2017 cohorts to Ireland and Germany were assessed with an additional pre- and post-test model that focused on travel efficacy, intercultural knowledge development, and interest in the pursuit of more international education or employment. Overall, students participating in the Jacks Start Abroad programs demonstrated increases in all of the dimensions measured. Although the authors observed similar changes in students during conversations and actions during and after the programs, the goals to expose students to cultural differences and contexts were documented in writing assignments where students compared/contrasted their new world views of their JSA destination and their home country.

Authors: Kumar P. Senthil
Published: February 2024

To determine the optimal value and solution for balanced and unbalanced intuitionistic fuzzy transportation problems (UBIFTPs), two different approaches are proposed in this chapter. Additionally, the parameters of the proposed problems are considered to be triangular intuitionistic fuzzy numbers (TIFNs). Two efficient methods, namely method-I (named linear programming method) and method-II (named PSK method), are presented. Both of them are used to solve the proposed problems. The ideas of these two methods are illustrated with the help of simple examples, and their relevant computer programming is presented. From software such as RStudio, LINGO, RGui, and MATLAB, the obtained solutions for the proposed problems are compared and analyzed with the solutions obtained by the proposed methodologies and already existing methodologies. The unique or superior results, discussions, advantages, and disadvantages of the proposed methods are all presented. Finally, the author's future work is mentioned.
Revolution Towards DC Microgrids
Authors: Maurya Rinki , Sharma Priya , Singh Ashutosh Kumar , Prakash Surya
Published: February 2024

A DC microgrid is a decentralized electricity system that uses direct current (DC) power for distribution and consumption. It is an alternative to the traditional alternating current (AC) microgrid, which is the dominant electrical distribution system used in most parts of the world. The adoption of DC microgrids has been gaining momentum in recent years due to their numerous advantages over AC microgrids, including improved energy efficiency, reduced power loss during transmission, and the ability to integrate renewable energy sources more easily. In this chapter, the authors review the technical and economic benefits of all types of possible grids and microgrids and discuss the challenges and opportunities associated with their deployment. Overall, the analysis suggests that the transition to DC microgrids is a promising approach for addressing the energy challenges of the 21st century and could play a significant role in the ongoing energy transition.

Authors: Kaliannan Kalaiselvi , Deepa Thilak K. , Bhuvaneswari R. , Prakash U. M. , Kumaresan K. , Selvan Shitharth
Published: February 2024

This chapter introduces a novel approach for the prediction of breast cancer and Parkinson's disease. The authors propose an ensemble of E-WNNs to enhance the accuracy and robustness of predictive models. To predict breast cancer from complicated medical data, the E-WNN ensemble uses wavelet transforms in neural networks. The ensemble's networks' structure and attributes are adjusted using evolutionary algorithms to develop a powerful forecasting framework. To predict Parkinson's disease, they employ E-WNN to study clinical assessments and patient history. They fine-tune ensemble members to discover small patterns that reflect disease progression, leading to a more accurate diagnosis. They evaluate the ensemble's performance in terms of classification accuracy, sensitivity, and specificity, highlighting its potential as a valuable tool for early detection and diagnosis of breast cancer and Parkinson's disease. In this study of medical predictive modeling, evolutionary algorithms and wavelet modification transformations are used to make disease prediction systems more accurate and reliable.

Published: February 2024

Neuron degeneration in the human brain causes Parkinson's disease (PD). The technique employed for detecting early PD is based on a parametric analysis of acoustic sounds. Machine learning methods such as SVM, KNN, decision tree, and random forest are used in a significant manner. When compared to machine learning, deep-learning (DL) algorithms always produce greater results. DL algorithms are utilized to assess the patient's voice record. In this work, the authors introduce the MAYFLY optimization algorithm, a nature-inspired metaheuristic optimization technique. The approach utilizes convolutional neural networks (CNNs) coupled with bi-directional gated recurrent units (BiGRUs) to leverage the temporal and spatial features of biomedical data. Experimental evaluations reveal that the proposed approach produces better accuracy of 98.31% and better precision rate (98.78%). These results demonstrate the potential of the MAYFLY-based CNN-BiGRU model in differentiating PD patients from healthy individuals.

Published: February 2024

Digital transformation across human activity has emerged as a critical evolutionary trend. It has not only led to the emergence of neo-business models but has disrupted traditional industries like automobile manufacturers and stakeholders. A ripple effect is visible in the distribution phase of the automobile value chain due to the rapidly evolving needs of automobile customers, awareness and access to digital platforms, and the need to enhance customer lifetime value by manufacturers. In this chapter, the digitalization of automobile distribution has been discussed in three aspects – customer acquisition, retail experience, and customer life-cycle management. Digitalization has not only helped automobile dealers reduce their customer acquisition costs but also driven higher customer engagement and satisfaction. As more customers become tech-savvy and digitally aware, automobile dealers and manufacturers will need to quickly adapt to the new normal of digitalization in order to remain relevant to customers, innovate sustainable business models, and unlock customer lifetime value.

Published: February 2024

Purslanes are frequently used in Brazil as potted plants and for landscaping because of their beautiful colored flowers. Despite their commercial importance, the genetic diversity within ornamental purslane remains largely unknown. Thus, a complete characterization of ornamental purslane resources is essential for its utilization since genetic variability is indispensable for the efficient development of new cultivars. This study aimed to evaluate genetic variability and recommend accessions to start a genetic breeding program for purslane (Portulaca umbraticola). Twenty purslane accessions were collected in public places in Areia City and Santa Rita City, Paraiba State, Brazil. The experiment was conducted in a greenhouse. An entirely randomized experimental design with 20 accessions and 5 replicates was utilized. Plants were evaluated for quantitative and qualitative traits. Data were submitted to analysis of variance and grouped by Scott–Knott’s criteria (p ≤ 0.05). The accessions were grouped using Tocher’s method based on the generalized Mahalanobis distance. Principal component analysis was also used to analyze the genetic divergence. There were significant differences (p ≤ 0.05) for all evaluated traits except for internode distance, plant height, and leaf length. The Scott–Knott criteria clustered the accessions into two groups for all traits except days to flowering (five groups). Tocher’s grouping based on Mahalanobis distance allowed the accessions to be separated into eight clusters. The genetic diversity observed in this study was supported by the consonance between the Tocher cluster method and the PC analyses. The traits that most contributed to genetic divergence among accessions were days to flowering (70.37%), flower length (6.10%), leaf width (3.89%), branch number (3.57%), and stem length (3.36%). Considering the criteria for use in outdoor spaces, wider plants with several large colored flowers, thicker stems, greener leaves, and earliness were interesting. Accessions 5, 7, 13, 14, 16, 18, and 20 should be selected as parents for further breeding programs. However, if the objective is to produce potted plants, dwarf plants with bigger leaves are desired, and accession 1 should be selected. This will create greater variability in segregating populations, which will increase the overall quality of ornamental use of this species. For those accessions with no reproductive verticils but with other excellent attributes, for example, high chlorophyll content breeding strategies, such as induced mutations or protoplast fusion, can be used.
Genetic diversity for agronomic and bromatological traits in forage cactus
Authors: Jesus Mariana Santos de , Passos Adriana Rodrigues , Diniz Rafael Parreira
Published: February 2024

This work aimed to estimate the genetic diversity in accessions of Opuntia ficus-indica collected in 13 regions of the semiarid region of Bahia. A total of 65 accessions were evaluated in a randomized complete block design, with three replications, at the Rio Seco experimental station belonging to the State University of Feira de Santana, Amélia Rodrigues-BA. Characterization of the accessions was made through the evaluation of 17 descriptors, namely 11 agronomic and six bromatological. The average Euclidean distance was used to estimate the genetic diversity among accessions. The shortest distances were obtained for accessions from the same collection site while the largest were observed in accessions 54 and 62 (10.32 DE) and 63 and 3 (10.22 DE). The analysis of canonical variables indicated cladodes total number (CTN), plant width (PW), CL, plant height (PH), ether extract (EE), and dry weight (DW) for discard as they presented the lowest contribution of the data set variation. Principal component analysis and K-means method were used to establish the clusters, and the formation of four groups was indicated. The first two principal components captured 52.5% of the total variation present in accessions. The descriptors with the greatest contribution to the variation observed in O. ficus-indica were total cladode photosynthetic area (TCPA), cladode area (CA), and cladodes width (CW). There is divergence between cactus forage accessions collected in the semiarid region of Bahia. This information will allow the use of these materials for the formation of segregating populations in the genetic improvement program of the State University of Feira de Santana. The accessions of groups III and IV should be explored by the forage cactus breeding program, as they presented greater productive potential.

Published: February 2024

Popcorn (Zea mays L. everta) is a specialty crop with a higher aggregate economic value than that of common maize. In Brazil, national literature is still incipient and contradictory in terms of plant population management and water requirements. Furthermore, the interaction between these factors has not been reported, despite the increasing cultivation of popcorn. The objective of this trial was to determine whether agricultural traits and popping expansion from hybrid IAC 125 could be affected by plant density and levels of irrigation water, in addition to determining the significance level of the interaction between both factors. We investigated five plant populations (40,000, 55,000, 70,000, 85,000, and 100,000 plants ha-1) and five different levels of water depth in 2014/2015 [574.86 (without supplementary irrigation), 609.86, 644.86, 679.86 (control), and 714.86 mm] and 2015/2016 [857.4 (without supplementary irrigation), 867.26, 886.60, 916.78 (control), and 959.81 mm] using a complete block design with split-plot, comprising a main plot (for plant populations) and subplot (for water depth), with six replicates for each set. We found increasing linear effects from grain yield under population density and levels of water depth, but this interaction was not significant. Moreover, the popping expansion for the main effects and the interaction between plant populations and water depth, were not significant.

Combinations between crop intercropping and forage production in a no-tillage system are not well established for environments under low water retention and soil fertility conditions. Our study aimed to evaluate the potential interactions between soybean-grass intercropping with residual nitrogen in a no-tillage system. The experimental design was a randomized block with four replications in a subdivided plot scheme. The main plots in the summer season were: 1) soybean monoculture; 2) soybean - Aruana Guinea grass (Megathyrsus maximus cv. Aruana) intercropping, and 3) soybean - Congo grass (Urochloa ruziziensis cv. Comum) intercropping. The subplots were the nitrogen rates of 0, 50, 100, and 150 kg ha-1, applied as side-dressing in maize and grasses during the autumn-winter season. Here, the results of the summer seasons are shown. To do so, the parameters evaluated were soybean agronomic traits, dry biomass production, and macronutrient concentrations of plants intercropped. The main effects and interactions were studied. Our findings showed that soybean-Aruana Guinea grass intercropping is an alternative to no-tillage system implementation. Moreover, residual nitrogen from the autumn-winter season directly interfered with the dry biomass production of grasses intercropped with soybeans in the summer season. In short, the systems studied seem suitable for implementing a no-tillage system, which aims to neutralize degraded pastures and produce forage for ensilage. Despite the changes in macronutrient concentrations within the intercropping system and residual nitrogen, and among intercropped crops over the years, Congo grass intercropped with soybeans in the summer season showed great capacity for phosphorus, potassium, and magnesium cycling.

Although acerola (Malpighia emarginata DC.) is a tropical fruit of high interest due to its high ascorbic acid content and attractive sensory attributes, fruit production is characterized by high genetic variability. Additionally, the use of new biometric tools for acerola breeding is scarce. This study aimed to estimate genetic parameters and the coefficient of repeatability, as well as determine the optimal number of fruits for quality trait analyses in different acerola genotypes, using different approaches. Twenty-three (Experiment I) and thirty-five (Experiment II) genotypes were evaluated in a randomized block design with four replicates and three plants per plot. Twenty fruits per plant were harvested and evaluated for the following quality traits: diameter, mass, skin color (lightness, chroma and hue), firmness, soluble solids (SS), titratable acidity (TA), SS/TA ratio, and ascorbic acid content. The genetic parameters and the coefficient of repeatability were estimated for each experiment using classical and Bayesian methods. Both approaches achieved similar results on estimating variance components, genetic parameters and the coefficient of repeatability. Genetic parameters showed favorable conditions for acerola selection. The coefficient of repeatability was high for all acerola quality traits. A total of 17 fruits are required for the effective selection of acerola genotypes with an accuracy of 95%.

The Spodoptera frugiperda, is one of the most deleterious pests of popcorn and the identification of resistant genotypes is determinant in breeding programs. The objective of this study was to select popcorn genotypes resistant to S. frugiperda and the key traits related to the identification of resistance. The popcorn varieties UEM J1, Composto Márcia, Arachida, Composto Gaúcho, and Zapalote Chico (resistant check) were evaluated in a completely randomized design with 100 replications. The experimental unit consisted of one Petri dish, containing plant material and a caterpillar The following traits were evaluated: larval stage duration (LSt), food intake weight(IW), final larva weight (FW), mean larva weight (MW), feces (F), assimilated (A) and metabolized food weight (M), relative consumption rate (RCR), relative metabolic rate (RMR), relative growth rate (RGR), conversion efficiency of ingested food (CEI), apparent digestibility (AD), conversion efficiency of digested food (CED), and leaf area consumed (LAC). The diagnosis of multicollinearity, analysis of canonical variables, genetic divergence, hierarchical clustering, factor analysis and canonical correspondence analysis were carried out to perform multivariate analysis. After the multicollinearity test, the traits FW, IW, RCR, AD, and LAC were maintained for further analysis. The traits IW, FW and AD were determinant in the resistance by antixenosis expressed by the varieties Zapalote Chico and Arachida, for the varieties Composto Gaúcho and Composto Márcia the determining characteristics were RCR and LAC and for the variety UEM J1 the variable LAC showed greater importance. Variety Arachida was considered resistant to S. frugiperda by antixenosis and can be used in the future as a source of favorable alleles to breed resistant popcorn hybrids. The traits relative consumption rate, apparent digestibility and leaf area consumed were considered key traits in the identification of resistance against S. frugiperda in popcorn genotypes.

This study aimed to evaluate the nutrient intake, milk production, and production costs of dairy goats fed diets containing the rations with cactus cladodes (Opuntia stricta or Nopalea cochenillifera) associated with silage (Sorghum bicolor) or Tifton hay (Cynodon spp). Twelve pluriparous Saanen and Anglo Nubiana goats (42.25 ± 5.48 kg) at eight weeks of lactation were used. Treatments lasted 60 days, consisting of four periods of 15 days, distributed in three Latin square (4×4) with four diets. The treatments represented by diets with different associated feed: SSOP (Sorghum Silage + Opuntia); THOP (Tifton hay + Opuntia); SSNO (Sorghum Silage + Nopalea); and THNO (Tifton hay + Nopalea), in addition to concentrate in all diets. There were differences (p < 0.05) for the intakes of DM, OM, with higher values observed for goats fed the diets THNO, THOP, and SSNO, and for CP, NDF and ADF were higher for THNO and SSNO diets. Similar behavior occurred for voluntary and total water intake. The milk production and feed efficiency did not differ (p > 0.05). Costs with food, milk revenue, and gross revenue were not influenced by diets (p > 0.05). The Opuntia or Nopalea cactus cladodes genotypes associated with sorghum silage or tifton hay can be used to feed dairy goats in the semiarid region.

The current study evaluates the effect of partial or total replacement of fish meal with Haematococcus pluvialis microalgae, cultivated in an NPK culture medium, on the growth performance of Macrobrachion amazonicum shrimp post-larvae. Four diets were formulated: control (without microalgae), 25, 50 and 100% H. pluvialis replacement. Only crude protein weight gain showed no interaction and was not selected for principal components analysis. The 25% fishmeal replacement in the diet was not effective, being similar to the control. However, the complete replacement of fishmeal with H. pluvialis promoted elevated survivability, length, weight and protein retention, making it the most relevant treatment for M. amazonicum post-larvae. Therefore, it is possible to completely replace fishmeal with the microalgae H. pluvialis in the diet of M. amazonicum shrimp, which improves growth performance.

Twenty-four lambs between four and five months of age were divided into sex classes: uncastrated males, castrated males and females, eight for each treatment, with an average body weight of 27.00 ± 3.13 kg. dry matter and water intakes were higher for uncastrated males (p < 0.001). final body weight, body weight at slaughter, average daily gain and cold carcass weight were greater for uncastrated, intermediate for castrated and lower for females (p < 0.05). hot and cold carcass yields were higher for castrated males and females, respectively. (p < 0.05). based on principal component analysis, twenty-five variables were selected out of thirty-two, in some of the seven principal components generated, summarizing 21.87% data dimension. Discriminant analysis identified greater discrimination power for body weight at slaughter, thorax width, thorax depth, fatness, dry matter intake and hot carcass weight. All lambs were classified into their respective sex classes. Therefore, uncastrated males have performed better than castrated ones and both showed higher performance than females. Females and castrated males showed higher carcass yield. Discriminant analysis indicated heterogeneity between sex classes.
