Effet de la fertilisation organique à base de litière foliaire de Jatropha curcas L. et Jatropha gossypifolia L. sur la culture de tomate (Lycopersicon esculentum Mill.) à Guider (Nord/Cameroun)
Authors: Anguessin Benjamine , Mapongmetsem Pierre Marie , Ibrahima Adamou , Fawa Guidawa 
Published: June 2021

La baisse de la fertilité des sols due à la mauvaise gestion des terres et l’utilisation excessive des engrais chimiques a motivé le regain d’intérêt dans la recherche de fertilisants organiques respectant l’environnement pour un développement durable. Pour évaluer l’efficacité agronomique des litières de Jatropha sur la production de la tomate, une étude a été conduite en champs dans des pots de 20 cm de diamètre. Le dispositif expérimental est un bloc de Fischer randomisé avec un total de 64 pots (4 traitements x 4 répétitions x 4 unités expérimentales). Les résultats ont montré que les litières de Jatropha curcas et Jatropha gossypifolia ont amélioré la croissance et le développement (le diamètre et la ramification de la tige, le nombre de feuille et de fruits ainsi que la masse des fruits) de la tomate par rapport au témoin. La litière de Jatropha curcas a induit une large amélioration de la masse des fruits (33,09 g) par rapport aux autres traitements : le témoin (19,99 g), la litière de Jatropha gossypifolia (20,44 g) et l’engrais chimique (24,02 g). Pour une culture dont on aimerait avoir des gros fruits l’utilisation des fertilisants organiques à base des litières de Jatropha curcas pourrait être conseillée.Mots clés : Fertilisant organique, Litière, Jatropha curcas, Jatropha gossypifolia, Nord-Cameroun.

English Title: Effect of organic fertilization based on leaf litter of Jatropha curcas L. and Jatropha gossypifolia L. on the tomato crop (Lycopersicon esculentum Mill.) in Guider (North Cameroon)The decline in soil fertility due to poor land management and excessive use of chemical fertilizers has induced new interest in the quest for environmentally friendly organic fertilizers for sustainable development. To assess the agronomic effectiveness of Jatropha litter on tomato production, a study was conducted in the field in pots of 20 cm in diameter. The experimental set-up is a randomized Fischer block with a total of 64 pots (4 treatments x 4 repetitions x 4 experimental units). The results showed that the litters of Jatropha curcas and Jatropha gossypifolia improved the growth and development (the diameter and branching of the stem, the number of leaves and fruits as well as the mass of the fruits) of the tomato compared to the witness. Jatropha curcas litter induced a large improvement in fruit mass (33.09 g) compared to other treatments: the control (19.99 g), Jatropha gossypifolia litter (20.44 g) and chemical fertilizer (24.02 g). For a crop from which we would like to have larger fruits, the use of organic fertilizers based on Jatropha curcas litter could be recommended.Keywords: Organic fertilizer, Litter, Jatropha curcas, Jatropha gossypifolia, North Cameroon.
Essai de gobetage des mycéliums de Pleurotus cystidiosus à Kinshasa en R.D. Congo
Authors: Kabamba Serge , Nzemoti Gregory , Mbadu Victorine 
Published: June 2021

Il a été montré que les fortes pluies et chaleurs réduisaient les rendements du Pleurotus cystidiosus. La présente étude visait à trouver une méthode de culture pouvant limiter les chutes de rendement de Pleurotus cystidiosus en saisons humides et chaudes. Deux techniques à savoir celle de la culture sur étagère et du gobetage ont été utilisées comme traitement appliqué chacun à un échantillon de 30 sachets de substrat ensemencé. Les moyennes des températures étaient de 28,2 °C pour la saison des pluies et de 25,5 °C pour la saison sèche L’analyse de la variance a révélé une différence hautement significative (p≤0,0000) entre le rendement obtenu avec la culture à l’étagère et celui obtenu avec le gobetage. Cette différence n’a été constatée que pendant la période des fortes chaleurs. Les moyennes des rendements sont respectivement de 378,8 ± 39,5 g en saison de pluies et de 474,3g ± 50,1 g en saison sèche pour la culture à l’étagère et 638,7 ± 64,8 g en saison des pluies et 531,3 ± 94,03 g en saison sèche pour le gobetage. Donc, le gobetage peut sauvegarder le rendement de Pleurotus cystidiosus pendant les périodes de fortes pluies et les plus chaudes de l’année.Mots clés : Myciculture, rendement, température, substrat, pleurote.

English Title: Casing test of Pleurotus cystidiosus mycelia in Kinshasa in D.R. CongoHeavy rains and heat have been shown to reduce the yields of Pleurotus cystidiosus. The aim of this study was to find an appropriate method to cultivate Pleurotus cystidiosus by preventing its fall in yield during high temperatures season of the year. Two techniques, namely that of the cultivation on the shelf and the casing, were used as treatment each applied to a sample of 30 bags of inoculated substrate. The average temperatures were 28.2 °C for the rainy season and 25.5 °C for the dry season. Analysis of variance revealed a highly significant difference (p≤0.0000) between the yield obtained with the culture on the shelf and that obtained with the casing. This difference was only seen during the hot weather. The average yields were respectively 378.8 ± 39.5 g in the rainy season and 474.3 g ± 50.1 g in the dry season for shelf cultivation and 638.7 ± 64.8 g in the rainy season and 531.3 ± 94.03 g in the dry season for casing. These results suggest that casing can safeguard the yield of Pleurotus cystidiosus during the hottest periods of the year.Keywords: Myciculture, yield, temperature, substrate, pleurotus.

Analysis of a Support Base Stand using Finite Element Analysis
Authors: Muhammad A. , Shanono I.H. 
Published: June 2021

In this paper, deformation, Von-Mises stress, and failure analysis were carried out on a base stand using ANSYS workbench. The structural design was carried out using SolidWorks software and then imported into the ANSYS workbench for analysis. The investigation is performed using four different materials, i.e., structural steel, aluminum alloy, carbon fiber, and copper alloy, with an applied loading force of 1000 N at the tip of the structure. This technique highlights a complete reaction of the structure to the loading force, therefore providing room for structural optimization to reduce the risk of unexpected failure and unnecessary material wastage. The results obtained were compared and analyzed to identify the best material capable of withstanding the subjected force. Based on the Von-mises result, Carbon fiber has the highest possible maximum stress value of 4.70e+07 Pa, followed by structural steel, then Copper alloy. At the same time, the aluminium alloy has the least minimum Von-Mises. Structural steel is the very best option based upon the analysis outcomes. Its factor of safety is above unity in all the designs, which indicates that the structure has been over-designed. For that reason, it is suggested that the structure needs to be enhanced.

Nonintrusive Method for Induction Motor Equivalent Circuit Parameter Estimation using Chicken Swarm Optimization (CSO) Algorithm
Authors: Aminu M. , Abana M. , Pallam S.W. , Ainah P.K. 
Published: June 2021

This paper presents a nonintrusive method for estimating the parameters of an Induction Motor (IM) without the need for the conventional no-load and locked rotor tests. The method is based on a relatively new swarm-based algorithm called the Chicken Swarm Optimization (CSO). Two different equivalent circuits implementations have been considered for the parameter estimation scheme (one with parallel and the other with series magnetization circuit). The proposed parameter estimation method was validated experimentally on a standard 7.5 kW induction motor and the results were compared to those obtained using the IEEE Std. 112 reduced voltage impedance test method 3. The proposed CSO optimization method gave accurate estimates of the IM equivalent circuit parameters with maximum absolute errors of 5.4618% and 0.9285% for the parallel and series equivalent circuits representations respectively when compared to the IEEE Std. 112 results. However, standard deviation results in terms of the magnetization branch parameters, suggest that the series equivalent circuit model gives more repeatable results when compared to the parallel equivalent circuit.

İslam Eserlerinde Kullanılan Altıgen Tabanlı Geometrik Desenlerin Çözümlenmesine Yönelik Yeni Bir Yaklaşım
Authors: ERYILMAZ Halil İbrahim , SELİMGİL Bahar 
Published: June 2021

Geometrik süslemeler tarihin hemen her döneminde kullanılmıştır. İslam eserlerinde Emevi, Abbasi, Karahanlı, Gazneli ve Büyük Selçuklu dönemlerinde geliştirilmiş, coğrafi bölge ve kullanılan malzemenin türüne bağlı olarak bu alanda farklı biçimlerde ortaya çıkmıştır. İran bölgesinde özellikle tuğla malzemeyle uygulanan kompozisyon biçimleri, Anadolu'ya taşındığında daha çok taş malzemeyle uygulanmıştır. Taşın yanında ahşap ve çinide de geometrik motifler önemli örneklerle zenginleşerek devam ettirilmiştir. Bezemenin her alanında hemen her malzemeyle uygulanmış olan geometrik kompozisyonlar bitkisel, yazı ve figürlü kompozisyonlar ile birlikte, Selçuklu, beylikler ve Osmanlı devirleri boyunca varlığını kesintisiz olarak sürdürmüştür.
İslam eserlerinde kullanılan geometrik desenler kare, beşgen, altıgen, yedigen, sekizgen, dokuzgen, ongen, on altıgen, yirmi dörtgen, daire gibi birbirinden farklı geometrik şekillerden oluşur. Konumuzla ilgili yapılmış herhangi bir envanter çalışması olmadığı için bazı kaynak kitaplardan ve internet sayfalarından elde edilen verilerden hareketle Fas, Hindistan, İran, İspanya, Mısır, Özbekistan, Suriye, Türkiye ile İngiltere’deki bazı müze ve kütüphanelerde tespit edilen toplam 223 eserdeki 39 farklı geometrik desen, 13 grup halinde incelenmiştir. Çalışmamızın sınırları gereği kronoloji, coğrafi konum ya da kullanılan malzeme farkı gözetilmeksizin sadece altıgen tabanlı geometrik desenler şekil bakımından incelenmiştir. Bu desenleri daha pratik olarak çizmek için tarafımızdan altıgen tabanlı yeni bir ızgara sistemi oluşturulmuştur. Bahsi geçen yeni yaklaşım budur. Ayrıca birbirine benzer ya da birbirinin varyasyonu kabul edilebilecek desenler gruplandırılmış, ortaya konulan yeni ızgara vasıtasıyla desenlerin çizimleri gösterilmiştir. Makalenin sınırları gereği detaylı desen analizi yapılamamıştır. Sadece desenlerin ızgaraya yerleşme biçimi gösterilmiştir.

Humanoid Robot Enhancing Social and Communication Skills of Autistic Children: Review
Authors: Yousif Mohammed 
Published: June 2021

Autism is a neurological disease that affects people’s social, communicational and mental abilities. This makes it difficult for them to express themselves and integrate seamlessly with other people and society as a whole. With the number of autism cases steadily increasing, researchers and caretakers alike around the world are working on finding a teaching technique to help with the therapy and education of autistic children. Due to the number of resources and expertise that are required for this operation, it has proven to be quite difficult to find such a teaching technique. The results of our literature survey also show that the USA has the most research in this field, followed by England and Spain. The aim of this paper is to study the interaction of autistic children with the humanoid robot NAO. Therefore, we developed different interactive activities and materials for testing the children’s attitude and engagement. After careful observation and experimenting, it was found that the children were much more engaged and excited during the lessons that involved the robot. This can be attributed to its simple and toy-like nature, which makes the lessons more fun and exciting. The children were also more responsive, absorbed more information overall and were even willing to learn new subjects that they previously avoided.

Im Territorialstaat Württemberg waren die Rahmenbedingungen und Voraussetzungen komplexer als in anderen Regionen Deutschlands. Württembergische Städte zählten nicht zu den besonders produktiven Druckzentren. Mit der 1477 gegründeten Universität Tübingen bestand ein institutionell fassbarer Kreis von Autoren und Leserschaft für wissenschaftliche Literatur. Daher verwundert es, dass selbst hier zunächst nur von 1498 bis 1501 und dann in einzelnen Jahren zu Beginn des 16. Jahrhunderts gedruckt wurde. Tübingen war in dieser Frühphase eine temporäre Durchgangsstation für Drucker, die mehrmals im Lauf ihres Lebens den Wirkungsort wechselten.

Published: June 2021

A quarta revolução industrial, Industria 4.0, carrega consigo o legado de assegurar a evolução humana, de forma a dispor ferramentas que podem auxiliar os tomadores de decisão em diversos campos, como: maior controle, desempenho e produtividade em todo o ciclo de vida de um projeto. Desta forma, o objetivo deste trabalho é analisar a relação entre a indústria 4.0 e a gestão de projetos por meio de análises de literatura, identificando os principais impactos das novas tecnologias no gerenciamento de projetos atual. Para a metodologia utilizou-se de um estudo bibliométrico e uma análise de conteúdo, utilizando a base de dados da Scopus. Através das análises foi possível classificar os documentos em seis pilares principais da Indústria 4.0 em relação ao gerenciamento de projetos: internet das coisas, sistemas cyber-físicos, big data, automação, inteligência artificial e computação em nuvem, assim como, observar como as novas tecnologias desenvolvem-se quanto ao gerenciamento de projetos. Além disso, nos dois últimos anos, notou-se um crescimento na quantidade de publicações sobre o tema revelando oportunidades para futuras pesquisas. Ademais, pode-se perceber que o setor privado promove o desenvolvimento de diferentes pesquisas de gerenciamento, como também, melhoramento dos sistemas já existentes com a implementação de computação em nuvem e internet das coisas, contribuindo assim, para a teoria sobre o tema. Percebe-se que os desafios para a implementação da Indústria 4.0 variam de acordo com cada país, devendo-se levar em consideração: o estágio de desenvolvimento das bases industriais, origem dos principais investidores e a existência de políticas públicas que incentivem o desenvolvimento de pesquisas sobre o tema, desta forma este estudo contribui para a prática organizacional quanto a comunidade em geral.
