Authors: Datta Debajit , Jamalmohammed Saira Banu
Published: October 2020

Image classification is a widely discussed topic in this era. It covers a vivid range of application domains like from garbage classification applications to advanced fields of medical sciences. There have been several research works that have been done in the past and are also currently under research for coming up with better-optimized image classification techniques. However, the process of image classification turns out to be time-consuming. This work deals with the widely accepted FashionMNIST (modified national institute of standards and technology database) dataset, having a set of sixty thousand images for training a model and another popular dataset of MNIST for handwritten numbers. The work compares several convolutional neural network (CNN) models and aims in parallelizing them using a distributed framework that is provided by the python library, RAY. The parallelization has been achieved over the multiple cores of CPU and many cores of GPU. The work also shows that the overall accuracy of the system is not affected by the parallelization.

Inequality in Pay Ranks Among Factors Impacting Job Satisfaction Among Female Physicians
Authors: Keltgen Jaciel Elizabeth
Published: October 2020

Job satisfaction has fallen among doctors, and beyond lack of pay parity that averages 25%, female physician job satisfiers differ from male colleagues. Health systems can build upon female physicians' confidence in their abilities to communicate with patients, show empathy, build trust, and elicit patient compliance with treatment plans. Systems must attend to work conditions for young and female cohorts, thereby retaining half of the workforce offering critical care to 7.8 billion people. Ordinal logistic regression was used to analyze data gathered in the U.S. by the Center for Studying Health System Change. Data were used to build a predictive statistical model in concert with independent variables linked to generational and job satisfaction literature. This study revealed statistically significant correlations between factors not only by gender, but also by generational membership. Statistically significant factors affecting job satisfaction among female physicians include provision of quality care to all patients, adequate time spent with patients and income.
3 R`s for Women Empowerment
Authors: Vijay Neeraja , Chandani Arti , V. Elumalayan S.
Published: October 2020

Women are no less than men. She herself is on par with a man. WO-MAN empowering is not only a verbal concept; it should be in practical life. She is no less than a man in any work assigned to her. She is always ill-treated as a weaker sex. But in the real life, she is more powerful than a man. Her commitment towards her work is always dedicated. She always tries to prove herself in any task assigned to her. This movement of women empowerment is not a new one. When you look back into the prehistoric period, women were treated as equal warriors, better half to men. They were strong enough in mind and soul. Then when and where did she lose her identity? Why is she treated as a weaker sex? Why she is deprived of her right to respect, recognition, and remuneration in the outer world with reference to her male colleagues? Through this chapter, the author is trying to shed light on the rights of a women, which she is deprived of since ages.
Providing Near-Peer Mentorship to Increase Underrepresented Minority Youth Participation in Computing
Authors: Lee Michael J.
Published: October 2020

Literature shows that mentors and role-models directly affect young students' self-efficacy and motivation to pursue specific academic fields and careers. To explore this further, this chapter describes a free, 9-Saturday programming camp for middle school students with near-peer mentors (first year, college student instructors) and local guest speakers. This camp served 28 underrepresented minority students (17 boys and 11 girls; grades 5-7) from a low-income, urban area. In a pre-camp survey, the middle school students predominately reported not having any role-models or mentors in computing. However, when asked again on the final camp day, these same students indicated developing strong connections with their near-peer mentors and even saw these older students and guest speakers, as role-models. These results highlight the need for young, underrepresented minority students to have more opportunities to interact with potential mentors and role-models, and the importance of providing resources to help develop and nurture these connections.
Female Enrolment in High School Computer Science Courses
Authors: Floyd Steven Paul
Published: October 2020

Jane Margolis and Allan Fisher's book Unlocking the Clubhouse: Women in Computing presented computer education as a clubhouse for boys that was resulting in women and girls being left out of the computer science (CS) loop. This research reveals that now, almost 20 years later, a number of doors, walls, and windows still inhibit certain students from equal access and participation to the computing clubhouse and provides data from Ontario, Canada indicating that females make up only 26%, 21%, and 15.7% of student enrolled in the Grade 10, Grade 11, and Grade 12 high school courses, respectively. Considering the number of initiatives and money related to expanding CS education, including a revision of high school CS curriculum in Ontario and $60 million of additional CanCodes money provided by the federal government, a better understanding of the underrepresentation of females in high school CS is critical.
Educational Robotics for Creating Effective Computer Science Learning for All
Authors: Eguchi Amy
Published: October 2020

President Obama's initiative, “computer science for all,” has been a rallying slogan for promoting computer science in K-12 education. Although the participation of people of color in computer science (CS) has increased in the past several years, it is still drastically low and does not reflect the real picture of our society. This chapter explores how educational robotics as a learning tool can inspire underrepresented minorities including females and students of color to become interested in CS. Supported by Papert's constructionism theory, educational robotics effectively facilitates students' learning of various concepts in CS and STEM. Educational robotics is a learning tool which inspires students' interest in learning. It provides a learning environment that promotes students' learning of various CS concepts and computational thinking skills. Although robots naturally spark students' interests, to make it most effective, teachers are required effortfully to create learning opportunities that are authentic and meaningful for individual students.

Such legal maneuvering may be useful to avoid human responsibility or to further automate businesses. In this chapter, after introducing pathways to AI personhood, consequences of such AI empowerment on human dignity, human safety, and AI rights are analyzed. This chapter per the author emphasizes possibility of creating selfish memes and legal system hacking in the context of artificial entities. Finally, potential solutions for addressing described problems are considered.
Ethical Rationality in AI
Authors: Holst Jonas
Published: October 2020

Taking its starting point in a discussion of the concept of intelligence, the chapter develops a philosophical understanding of ethical rationality and discusses its role and implications for two ethical problems within AI: Firstly, the so-called “black box problem,” which is widely discussed in the AI community, and secondly, another more complex one which will be addressed as the “Tin Man problem.” The first problem has to do with opacity, bias, and explainability in the design and development of advanced machine learning systems, such as artificial neural networks, whereas the second problem is more directly associated with the prospect for humans and AI of becoming full ethical agents. Based on Aristotelian virtue ethics, it will be argued that intelligence in human and artificial forms should approximate ethical rationality, which entails a well-balanced synthesis of reason and emotion.
Steps Toward Real-World Ethics for Self-Driving Cars
Authors: Holstein Tobias , Dodig-Crnkovic Gordana , Pelliccione Patrizio
Published: October 2020

Research on self-driving cars is transdisciplinary and its different aspects have attracted interest in general public debates as well as among specialists. To this day, ethical discourses are dominated by the Trolley Problem, a hypothetical ethical dilemma that is by construction unsolvable. It obfuscates much bigger real-world ethical challenges in the design, development, and operation of self-driving cars. The authors propose a systematic approach that connects processes, components, systems, and stakeholders to analyze the real-world ethical challenges for the ecology of socio-technological system of self-driving cars. They take a closer look at the regulative instruments, standards, design, and implementations of components, systems, and services, and they present practical social and ethical challenges that must be met and that imply novel expectations for engineering in car industry.
Machines and Technological Unemployment
Authors: Moser Elias
Published: October 2020

Recently, economic studies on labor market developments have indicated that there is a potential threat of technological mass unemployment. Both smart robotics and information technology may perform a broad range of tasks that today are fulfilled by human labor. This development could lead to vast inequalities. Proponents of an unconditional basic income have, therefore, employed this scenario to argue for their cause. In this chapter, the author argues that, although a basic income might be a valid answer to the challenge of technological unemployment, it fails to account for some ethical problems specific to future expectations of mass unemployment. The author introduces the proposal of an unconditional basic capital and shows how it can address these problems adequately and avoid objections against a basic income. However, the basic capital proposal cannot replace all redistributive social policies. It has to be interpreted as a supplement to either a basic income or more traditional redistributive policies.

Authors: Bala Shashi , Kumar Raj , Singh Jeetendra , Sharma Sanjeev Kumar
Published: October 2020

This chapter presents the design and simulation analysis nanowire-based FET (NWFET) for best possible Ig-Vgs characteristics. A NWFET is a device in which channel is wire-like structure with diameter or lateral dimension in nanometer (10-9 m) range. Performance analysis has been done for various design and process parameters variation to propose optimized parameter for best performance. Although a lot of focus has been put on homogenous Si based NWFETs, there has been a rising interest in III-V NWFETs. This is mainly due to the excellent carrier transport properties are provided by these materials. NWFETs have ability to suppress SCEs and are also good in suppressing OFF-current (IOFF), because of gate all around (GAA) configuration. Secondly, NWFETs have large ON-current (ION) due to quasi one-dimensional (1D) conduction of NWs, and as a result of low carrier scattering, conduction of NWs-based devices is very large.

Interior Designing in the Urban Environment
Authors: Attiwill Suzie
Published: October 2020

The 21st century is a time of significant change to and in urban environments and cities. The momentous and unrelenting movement of people seeking refuge in cities other than their own; the impact of weather, pandemics, terrorism and war; the effect of technology; and the transformation of concepts such as public and private highlight the urgent need to think differently about cities in relation to inhabitation. It seems appropriate, indeed vital, to bring the expertise, techniques, and concerns of the interior designer and interior architect into the urban realm to attend to how people might inhabit the urban environment. This chapter curates a series of propositions that position the practice of interior design in the urban environment. Each proposition engages a different theoretical framework in relation to the concept of “interior” and, as a consequence, a different methodology.
Towards Interior Architecture Design V4.0
Authors: Arabacioglu Burcin Cem , Karayilanoglu Gamze , Gulel Zeynep
Published: October 2020

In the history of design, it may be remarked that the world is in a new paradigm shift at the level of breaks in the transition to agriculture, industry, and information societies. As in many fields of design, interior design is also evolving in terms of design thinking as well as being subject to change in all processes under the influence of intensive technological development. While information technologies are implicated as aides in the design processes in the early stages of this evolution, they are now used for creating unique design and production approaches. This chapter discusses and re-interrogates the contributions and effects of these developments on the structure of interior design methodologies.
Corporeal Architecture
Authors: Ferreira Maria da Piedade
Published: October 2020

This chapter describes a teaching method, corporeal architecture, which uses performance art and neuroscience to teach interior design and architecture with a focus on embodiment and experience. The method sets new approaches to teach design, as it integrates design, neuroscience, and performance art and brings awareness to the importance of multi-sensory experience. The interaction with design objects at different scales is taken as an opportunity to investigate how the human body relates to space and allow the exploration of affordances through movement. Students are instructed with physical exercises and encouraged to design, build, and perform with objects such as chairs, cabinets and tables, installations, existing buildings, and public spaces. The performances explore narratives which reveal or subvert expectations we have around design objects. The methodology has a background in phenomenology, Maurice Merleau-Ponty and Juhani Pallasmaa; Antonio Damásio in neuroscience; and Oskar Schlemmer, Marina Abramovic, and Stelarc in Performance Art.

An Analysis on Task Migration Strategy of Big Data Streaming Storm Computing Framework for Distributed Processing
Authors: Hu Xiling
Published: October 2020

In this modern era, a large volume of data is generated regularly, which needs to be processed for gaining profits of latent information. The processing of big data is composed of a challenge termed as communication overhead. In order to minimize communication overhead on the premise of various resource constraints, a task migration strategy under heterogeneous storm environment is proposed. The proposed strategy is based on the establishment and demonstration of storm resource constraint model, optimal communication overhead model, and task migration model. Where the source node selection algorithm adds the nodes beyond the threshold to the source node set according to the load of CPU, memory, and network bandwidth of each working node in the cluster and the priority order of various resources. The experiment shows that compared with the existing research, computing storm can effectively reduce the delay and communication overhead between nodes, and the execution overhead is small.
“The Fact That the Author Was Male Instead of Female Provided for an Objective Opinion”
Authors: Waity Julia Ferrara , Vanderminden Jennifer , Robeson Kristin
Published: October 2020

This paper presents an audit-style experiential learning activity intended to gauge students' perceptions of objectivity based on author gender, encourage students to apply the concept of bias to their own learning, and participate in a research study. In this activity, students were unknowingly randomly assigned the same reading on the gender wage gap with either a “male” or “female” author. Although the differences were not statistically significant, student numerical ratings of objectivity were higher when they believed the author was male. The discussion and reflection assignments demonstrated that this exercise provided students with a unique opportunity to evaluate their own biases, engage in discussion about bias, and apply course materials. Written rationale for ratings supported this perception that male authors were more objective. This activity is useful for students in thinking about and discussing the impact of implicit bias.
A Transformer-Based Model for Multi-Track Music Generation
Authors: Jin Cong , Wang Tao , Liu Shouxun , Tie Yun , Li Jianguang , Li Xiaobing , Lui Simon
Published: October 2020

Most of the current works are still limited to dealing with the melody generation containing pitch, rhythm, duration of each note, and pause between notes. This paper proposes a transformer-based model to generate multi-track music including tracks of piano, guitar, and drum, which is abbreviated as MTMG model. The proposed MTMG model is mainly innovated and improved on the basis of transformer. Firstly, the model obtains three target sequences after pairwise learning through learning network. Then, according to these three target sequences, GPT is applied to predict and generate three closely related sequences of instrument tracks. Finally, the three generated instrument tracks are fused to obtain multi-track music pieces containing piano, guitar, and drum. To verify the effectiveness of the proposed model, related experiments are conducted on a pair of comparative subjective and objective evaluation. The encouraging performance of the proposed model over other state-of-the-art models demonstrates its superiority in musical representation.

SEM MITO NEM CAVERNA
Authors: Seabra Pereira Leite Amanda Marilia , Santos Dominique Vieira Coelho dos
Published: October 2020

Criado em 2004, o projeto chamado de “Escola sem Partido” ganhou notoriedade nos últimos anos, sobretudo a partir de 2014, quando recebeu apoio da família Bolsonaro. Apesar da nomenclatura, trata-se de uma proposta conservadora, de direita, e que esconde interesses políticos e partidários. Além disso, ela tem sido interpretada como algo que fere a Constituição Federal, a Lei de Diretrizes e Bases da Educação e o Estatuto da Criança e do Adolescente e, por isso, recebido inúmeras críticas, tanto no âmbito legal quanto no educacional. Além destas tensões, acreditamos que o projeto é um cavalo de Tróia que carrega consigo outros perigos, pois, se implementado, a “Escola sem Partido” poderia representar também uma “Escola sem Sujeito”. Essa é a problemática discutida no artigo. Mobilizando o léxico psicanalítico, sobretudo o conceito de “alienação”, visto sob a ótica das contribuições da psicanálise freud-lacaniana, fazemos uma leitura desse debate, alertando para os riscos de uma fragmentação dos sujeitos envolvidos nos processos de ensino-aprendizagem na Educação Brasileira.

O objetivo desta pesquisa foi investigar o desenvolvimento cognitivo de um grupo de idosos/as, em particular, os procedimentos de formação de possíveis e do necessário, por meio de uma intervenção pedagógica construtivista e intergeracional. Participaram da pesquisa sete idosos/as da Universidade Aberta à Terceira Idade/UEM e quatro alunas do curso de Pedagogia da mesma instituição. A pesquisa foi realizada na modalidade pesquisa participante e organizada com base na teoria piagetiana. Do processo de intervenção pedagógica constaram jogos de regras e atividades-desafio realizadas em grupos intergeracionais. Antes e depois das sessões de intervenção pedagógica aplicaram-se provas operatórias e dilemas de Kohlberg. Os dados produzidos pelos/as participantes evidenciaram desenvolvimento dos esquemas procedimentais de criação de possíveis e do necessário tanto nos dilemas de Kohlberg como nas atividades-desafio analisadas. Conclui-se que o desenvolvimento dos/as idosos/as nessas atividades é decorrente da atualização de seu sistema cognitivo aos níveis encontrados nas provas operatórias que desde o início da pesquisa mostraram-se compatíveis com os mais complexos quanto aos procedimentos de formação de possíveis e do necessário. Essa atualização cognitiva pode ser creditada às condições construtivistas da intervenção pedagógica realizada com os/as participantes da pesquisa que se mostrou fecunda para a educação formal dessa faixa etária.

Published: October 2020

The cocoon of Antheraea pernyi was grown in the laboratory with tropical artificial conditioning. The caterpillar was fed with Lantana camara leaf. They are 3 protocols provided to yield single fiber from the cocoon. The first protocol developed in this work was based on the single fiber drawing directly from the live caterpillar during cocoon stage establishment (forcibly silking). The single fiber was gently pulled and rolled up manually. The second protocol was conducted by degumming the cocoon with boiling in 5%NaoH solution. The cocoon was boiled in 5% NaOH solution and gently stirred. When the fiber was found detached from the cocoon, the boiling process was stopped, and the fiber obtained was washed with water and dried in the oven. The third protocol was simple boiling of the cocoon with water and gently stirring until the cocoon disintegrated to become a fiber. The fiber obtained was washed and dried in the oven. The first protocol by forcibly silking produced fiber with highest tensile strength of average value of 149.251 MPa. The other protocols introduced in this work resulted in lower tensile strength. Alkali treatment provided average tensile strength of 43.833 MPa and boiling in water resulted in tensile strength 52.571 MPa.

Authors: Harnkla Preeyaporn , Chienthavorn Orapin , Akkarachaneeyakorn Khrongkhwan
Published: October 2020

Dentine hypersensitivity (DH) is a common issue among humans caused by the erosion of tooth enamel as a result of chewing and brushing incorrectly. The most effective treatment method is occluding the exposed dentine tubules. Because calcium phosphate is an important mineral and the most common mineral for dentine and orthopaedic application, this study focuses on the synthesis of bioactive gels containing calcium phosphate nanoparticles. The synthesis is performed using water-in-oil emulsion and characterized by the use of TGA, Rheological, TEM, and SEM techniques. This method used oleic fatty acids as an external phase and Tween 20 as surfactant to form water-in-oil nanodroplets. Gelatine was used to form the substance into a gel and increase its stability. The resulting nanoparticles had the same spherical shape and a similar size. Therefore, the varying amounts of gelatin do not affect the particle size. However, viscoelastic properties of gels were found to be changed. The ability of the gel for dentine tubule occlusion was investigated using SEM techniques. After 1 day, it was found that the gels can occlude dentine tubules.

Aedes aegypti is almost completely restricted to human-modified environments, especially urban areas, and rarely invades forests. Ovitraps were utilized in a reserve (Bom Retiro) in Rio de Janeiro state. Eggs of A. aegypti, genetically not differentiable from those of urban mosquitoes, were obtained at a location more than 700 m inside the border of the forest and 900 m away from a trail at the entrance to the forest. The presence of A. aegypti in a primary forest indicates its ability to adapt to sylvatic environments in Brazil, suggesting great potential for the transmission of several arboviruses due to the difficulty in controlling these mosquitoes.
Divisibility of torsion subgroups of abelian surfaces over number fields
Authors: Cullinan John , Yelton Jeffrey
Published: October 2020

Let A be a two-dimensional abelian variety defined over a number field K. Fix a prime number
$\ell $
and suppose

$\#A({\mathbf {F}_{\mathfrak {p}}}) \equiv 0 \pmod {\ell ^2}$
for a set of primes

${\mathfrak {p}} \subset {\mathcal {O}_{K}}$
of density 1. When

$\ell =2$
Serre has shown that there does not necessarily exist a K-isogenous

$A'$
such that

$\#A'(K)_{{tor}} \equiv 0 \pmod {4}$
. We extend those results to all odd

$\ell $
and classify the abelian varieties that fail this divisibility principle for torsion in terms of the image of the mod-
$\ell ^2$
representation.
Surjective isometries of metric geometries
Authors: Beardon A. F. , Minda D.
Published: October 2020

Many authors define an isometry of a metric space to be a distance-preserving map of the space onto itself. In this note, we discuss spaces for which surjectivity is a consequence of the distance-preserving property rather than an initial assumption. These spaces include, for example, the three classical (Euclidean, spherical, and hyperbolic) geometries of constant curvature that are usually discussed independently of each other. In this partly expository paper, we explore basic ideas about the isometries of a metric space, and apply these to various familiar metric geometries.
Квантовая механика стационарных состояний частиц в пространстве-времени классических черных дыр

Рассмотрено взаимодействие скалярных частиц, фотонов и фермионов с гравитационными и электромагнитными полями Шварцшильда, Райсснера-Нордстрeма, Керра и Керра-Ньюмена с нулевой и ненулевой космологической постоянной. Рассмотрено также взаимодействие скалярных частиц, фотонов и фермионов с неэкстремальными вращающимися заряженными черными дырами в минимальной пятимерной калибровочной супергравитации. Проанализировано поведение эффективных потенциалов в релятивистских уравнениях второго порядка типа Шредингера. Во всех случаях установлено существование режима "падения" частиц на горизонты событий. Альтернативой могут являться составные системы без режима "падения" частиц: коллапсары с фермионами, находящимися в стационарных связанных состояниях.

Пусть $R$ - коммутативная комплексная алгебра и $\partial$ - $\mathbb{C}$-линейное дифференцирование в $R$ такое, что все его степени являются $R$-линейно независимыми. Пусть $R[\partial]$ - алгебра дифференциальных операторов с коэффициентами из $R$, а $Psd$ - ее расширение до алгебры псевдодифференциальных операторов. В алгебре $R[\partial]$ найдены приведенные дифференциальные операторы $\mathbf M_n$ порядка $n\ge 2$ без постоянного члена, удовлетворяющий системе уравнений Лакса, которая определяется лежащим в основе строгой иерархии КП разложением алгебры $Psd$ в прямую сумму двух алгебр Ли. Поскольку этот набор уравнений Лакса является аналогом такого разложения для $n$-й иерархии КдФ, он назван строгой $n$-й иерархией КдФ. Данная система имеет минимальную реализацию, и это позволяет показать, что она обладает свойствами однородности. Кроме того, показано, что система совместна, т. е. строго дифференциальные части операторов $M=(\mathbf M_n)^{1/n}$ удовлетворяют условиям нулевой кривизны, которые являются достаточными для вывода уравнений Лакса для $\mathbf M_n$ и, в частности, для доказательства того, что корень $n$-й степени $M$ из $\mathbf M_n$ есть решение строгой иерархии КП тогда и только тогда, когда $\mathbf M_n$ - решение строгой $n$-й иерархии КдФ. Охарактеризовано место решений строгой $n$-й иерархии КдФ среди ранее известных решений строгой иерархии КП.

La dégradation forestière provoque la perte de carbone et contribue indirectement au changement climatique. Afin d’évaluer la contribution du massif forestier de l’Ecole Nationale des Eaux et Forêts (ENEF) à l’atténuation du changement climatique, une étude d’estimation du stock de carbone a été menée. Dans cette étude, la quantité de carbone ligneux a été estimée dans des placettes carrées de 900 m2 pour la savane, 400 m2 pour la plantation de Tectona (P Teck) et 2500 m2 en zone agroforestière (Z Agf). L’équation de type polynomial et le modèle allométrique ont été utilisés pour l’évaluation du stock de carbone. Dans la savane, le carbone stocké dans la biomasse épigée s’élève à 17,66 ± 22,05 tC/ha et celui de la biomasse hypogée ainsi que de la végétation herbacée ont été respectivement de 2,28 ± 2,41 tC/ha et de 1,39 ± 0,61 tC/ha. Au niveau de la plantation de teck et de la zone agroforestière, les quantités de carbone contenues dans la biomasse aérienne ligneuse ont été respectivement de 54,38 ± 12,04 tC/ha et 2,50 ± 3,28 tC/ha contre 7,09 ± 1,40 tC/ha et 0,35 ± 0,42 tC/ha dans les racines. Cette étude contribue à la compréhension de l’apport de la savane, de la plantation et du système agroforestier ; à la séquestration du carbone. Des actions de renforcement du potentiel ligneux de cet écosystème s’imposent pour minimiser la dégradation de ce site à long terme et afin qu’il soit une source durable de séquestration du carbone. .Mots clés : Biomasse, stock de carbone, changement climatique, savane, zone soudanienne, Burkina Faso. Forests degradation causes carbon loss and contributes indirectly to climate change. In order to estimate the contribution of the forest of ENEF (called Ecole Nationale des Eaux et Forêts) forest in the mitigation of climate change, a work based on carbon stock in the forest was implemented. In this study, the quantity of ligneous carbon was estimated in some squares of 900 m 2 for the savannah, 400 m2 for the Tectona plantation (P Teck) and 2500 m2 for the agroforestry area (Z Agf). The equation polynomial and the allometric standard were used to evaluate carbon storage. In savannah, the carbon stocked in above ground biomass was 17.66 ± 22.05 tC/ha. The contribution roots and herbaceous is respectively 2.28 ± 2.41 tC/ha and 1.39 ± 0.61 tC/ha. In teak plantation and agroforestery land, the carbon stocked in AGB was respectively 54.38 ± 12.04 tC/ha and 2.50 ± 3.28 tC/ha. Concerning the roots, it is respectively 7.09 ± 1.40 tC/ha and 0.35 ± 0.42 tC/ha. The actions to strengthen the wood potential of this ecosystem are needed to minimize the degradation of this site in the long term and to be a source of carbon sequestration.Keywords : Biomass, carbon storage, climate change, savannah, soudanian zone, Burkina Faso.
Evaluation des paramètres productifs et quantification d’aflatoxine de sept variétés de maïs (Zea mays L.) testées en Haïti
Authors: De Marinis Pietro , Spada Alberto , Aristil Junior
Published: October 2020

Le maïs est la deuxième céréale la plus consommée en Haïti après le riz. Mais, le rendement (Rdt) national reste faible avec de risque élevé de contamination d’aflatoxines (AF). L’objectif de cette étude est d’évaluer les paramètres productifs de 7 variétés de maïs testées dans une approche participative à Torbeck et quantifier les AF. Deux des variétés proviennent de l’Université des Etudes de Milan (UNIMI), 2 de la Faculté d’Agronomie de l’Université Notre Dame d’Haïti et les 3 autres auprès des planteurs de Torbeck. Les résultats ont révélé que les Rdt maximal (4,36 t/ha) et minimal (3,14 t/ha) ont été détectés sur Tilevy, fournie par les producteurs et R4865, provenant d’UNIMI (p<0,05). La corrélation maximale du Rdt a été notée avec la masse des 100 grains (ρ=0,485) suivie du nombre grains par rang (ρ=0,477). Les concentrations d’AF varient de Comayagua (Max : 7,6 ; moyenne : 5,6±1,8 ppb) à Maquina (Max : 151 ; moyenne : 79,65±72,56 ppb). R4865 provenant d’UNIMI a révélé des taux d’AF < 20 ppb, fixé par la législation américaine. Ainsi, la variété R4865 d’UNIMI peut être donneuse de pollen à Tilevy dans des programmes ayant pour but de produire de grandes quantités de grains de qualité en Haïti.Mots clés: Variétés, maïs, rendement, aflatoxine, Haïti.
