Gravitational radiation from instabilities in rotating compact stars
Authors:   , Houser Janet Lynn , Centrella Joan M.
Published: March 2023

We present 3D numerical simulations of the non-axisymmetric dynamical bar mode instability in a rotating star, as well as the resulting gravitational radiation (calculated in the quadrupole approximation). This instability may operate during the collapse of rapidly rotating stellar cores or in white dwarfs spun up by accretion. Using a smoothed particle hydrodynamics (SPH) code, we have investigated the effects of the stiffness of the polytropic equation of state, and the randomness of the initial state on the gravitational wave quantities, growth rate, and pattern speed of the bar mode instability. The star is modeled as a polytrope with indicies n = 1.5, n = 1.0, and n = 0.5 and initially possesses T_rot/|W| ~ 0.30, where T_rot is the rotational kinetic energy and |W| is the gravitational potential energy of the entire system. The conclusion of this analysis shows that all models deform into a bar shape and shed mass in the form of a two-armed spiral pattern which transports angular momentum out of the core into the envelope via gravitational torques. For the softer equations of state, the system evolves toward a nearly axisymmetric state consisting of a dense core and surrounding uniform quasi-Keplerian tenuous disk with the system T_rot/|W| [less than or equal to] 0.26. A randomly generated initial model expels only ~5% of its original mass and only ~19% of its original angular momentum. However, a cooled initial model expels ~9% and ~30% of its original mass and angular momentum, respectively. We also find that a typical neutron star will radiate from ~0.1% to ~0.31% of its mass and ~0.7% to ~2.0% of its angular momentum in the form of gravitational radiation depending on the randomness of the initial state. As the equation of state stiffens, a typical neutron star will radiate from ~0.31% to ~0.67% of its mass and ~2.0% to ~5.6% of its angular momentum in the form of gravitational waves. The characteristic frequency of these waves will range from ~1kHz to ~5kHz, depending on the radius when the instability occurs, and the dimensionless amplitude will be h ~ 4.0 x 10^-22 at the distance of the Virgo Cluster.
The communications performance of single-carrier and multi-carrier quadrature amplitude modulation in RF carrier phase noise
Authors:   , Howald Robert L. , Kesler Stanislav B.
Published: March 2023

Multi-carrier modulations have generated strong interest recently because of the challenging characteristics of important contemporary channels. While the idea of partitioning spectrally using orthogonal frequency division multiplexing (OFDM) was developed over thirty years ago, its implementation as a practical solution to a communications system problem is much more recent due to advances in digital signal processing and VLSI. Implementation has brought about a simultaneous increase in developing analysis that allow the performance characteristics of the approach to be understood in practical channels. Example channels where OFDM is being strongly considered are data communications over CATV channels and wireless applications such as digital terrestrial broadcasting. Widespread consideration of OFDM as a primary transport mechanism has occurred to date only for high speed data over the twisted pair channel. In this application, the technology is referred to as the Asymmetric Digital Subscriber Line (ADSL). Unlike that application, however, CATV and wireless systems represent RF channels. As such, one important characteristic of each is the phase jittery nature of low-cost, high frequency synthesized carriers. The research will present unique results indicating how these impairments degrade the OFDM system. The approach taken is to model the untracked jitter variation as a lowpass process, note the breakdown of traditional assumptions associated with single carrier modulations, and proceed with analytical solutions from this practical model. The single carrier solutions required are developed, including solutions for slow and rapid phase noise for standard and offset 16-QAM. Results for 64-QAM are also developed, and can be easily extended to any rectangular constellation, such as 256-QAM or 1024-QAM. A comparison of the various simplifying analysis assumptions is made to contrast with exact performance curves when phase noisy RF channels are encountered. A straightforward technique to improve link margin on phase-noise limited, slow jitter channels is presented. Finally, system design guidelines are developed for the difficult moderately varying jitter situation, critical for multi-carrier systems that rely on multiple subchannels of individually low symbol rate.
Computational issues in the design of robust nonlinear controllers
Authors:   , Hu Shr-Shiung , Chang Bor-Chin
Published: March 2023

Just like the algebraic Riccati equations (AREs) or inequalities (ARIs) in the linear H[infinity] control theory, the Hamilton-Jacobi equations (HJEs) or inequalities (HJIs) play an essential role in the nonlinear H[infinity] control theory. In this thesis, a successive algorithm for finding an approximate solution of HJE is proposed. Using the existing nonlinear H[infinity] controller formulas, a numerical difficulty could be encountered when a critical assumption is not satisfied. We propose modified nonlinear H[infinity] controller formulas to eliminate the numerical difficulty. The proposed nonlinear H[infinity] controller is identical to the existing nonlinear H[infinity] controller if the assumption is satisfied, and its linear version will be the same as that designed by conventional linear H[infinity] approaches. An important application of the modified nonlinear H[infinity] controller formulas is the H[infinity] approximate input/output (I/O) linearization problem, which essentially is a nonlinear H[infinity] control problem without satisfying the critical assumption. Like the feedback I/O linearization, the H[infinity] approximate I/O linearization modifies a nonlinear system so that its I/O relationship resembles that of a linear system. However, the H[infinity] approximate I/O linearization can handle more general problem since it does not require minimum phase plant or full state feedback. The linearization technique together with [mu]-synthesis is used to design a robust nonlinear controller. An inverted pendulum control problem and a nonminimum phase longitudinal flight control problem are employed to illustrate the design of robust nonlinear controllers.
An Exploratory Study on the Deaths of Despair in Korea
Authors:   Research Institute For Life And Culture Sogang University, kwon jin , Min Hye young , Kang Sun Kyoung
Published: March 2023

This study is an exploratory study that introduced the overall empirical and theoretical discussions on the concept of despair that began in the United States, and applied them to Korean society. It is important and urgent to apply the concept of hopeless death in a Korean context to the concept that seems to have accumulated influence over a long period of time, although it is somewhat unfamiliar. As a result of examining theoretical discussions on the derivation of the concept of despair and previous studies on despair conducted in the United States and Europe, many scholars agreed that socioeconomic changes lead to cumulative deprivation and unhealthy behavior. On the other hand, there was an important discovery in that countries such as Germany did not have a pattern of despair due to a stable social security system compared to the United States. Based on statistics on the cause of death or social survey data in Korea, the rate of suicide, drinking, and drug deaths over the past decade reached 12.4% of the total death data. Dangerous drinking and suicidal thoughts were on the decline, but negative responses to social isolation and overall life conditions were increasing. Based on this empirical analysis, diagnosis and policy implications for Korean society related to despair were discussed.

Online learning has been running in Indonesian universities due to the COVID-19 outbreak. Online learning has become a challenge to both parties, lecturers, and students with special needs. The use of several online platforms for learning has not provided accessibility for students who are blind and deaf. To pursue friendly learning in inclusive classrooms for blind and deaf students, then we need a facility that supports learning for blind and deaf students. The purpose of the study is to develop a learning model that can be used for online learning using an interactive website. The interactive Web-Based Learning Model is an innovative learning model which is designed for special needs students to access online learning more effectively. The procedure used in this interactive web-based learning model is that every blind and deaf student can access learning through various devices connected to their cell phone or laptop to make the learning process two-way and effective. The research was conducted using the research & development method which consists of the stages of producing a model product and then validating and testing the model. The result of this study is an online learning model using a website that can present learning material from lecturers in the form of pages that all the menus can be read directly by blind students through a screen reader on their devices (user friendly) and they can send assignments via voice note options. The website is equipped with videos accompanied by subtitles so that it has accessibility to deaf students. This model consists of the following stages: 1) Planning which includes needs analysis and content analysis, 2) The learning process through an interactive website containing structured learning material, interactive learning through video and discussion features, 3) Evaluation includes test and non-test in the form of process and result in analysis.

Authors: TAŞ Sevinç , YAVUZ Ayşe
Published: March 2023

The Covid-19 epidemic that occurred in 2019 prevented education from continuing face to face. Various searches were conducted as part of this procedure that can be used effectively in online education. As a result, the GeoHepta mobile application was created to help students study the 7th grade mathematics course subjects using the ADDIE design methodology. Activities using dynamic mathematics software that students may use interactively were created as part of the content of the built mobile application. Students were also given the opportunity to complete online evaluation using Web 2.0 tools after learning the lesson's topics. The research was performed by 7th-grade students in a secondary school in the Central Anatolia Region in the second term of the 2020-2021 academic year, utilizing a mobile application in the distance education process. A quasi-experimental design was used to conduct the study. The “Mobile Application Usability Scale” was involved in the analysis to assess the usability of the mobile application after the experimental group had been educated. As a result of the research, it was established that the GeoHepta mobile application is "usable" by the students, and their attitudes about the mobile application are good. Participants' opinions on the mobile application's style, colour, control, typeface and hierarchy are also "useful". The "control" function of the mobile application received the greatest score, while the "aesthetic" aspect of the mobile application received the lowest grade.

This Expert Council focuses on the meta-analysis of studies on the risk of atrial fibrillation (AF) in patients taking omega-3 polyunsaturated fatty acids (PUFA) and of data on the omega-3 PUFA treatment in patients with cardiovascular and kidney diseases.

The major statements of the Expert Council: the meta-analysis of AF risk in patients taking omega-3 PUFA showed an increased risk of this arrhythmia. However, it should be taken into account that the risk of complications was low, and there was no significant increase in the risk of AF when omega-3 PUFA was used at a dose of ≤1 g and a standard dose of the only omega-3 PUFA drug registered in the Russian Federation, considering all AF episodes in the ASCEND study.

At the present time, according to Russian and international clinical guidelines, the use of omega-3 PUFA can be considered in the following cases: • for patients with chronic heart failure (CHF) with reduced left ventricular ejection fraction as a supplement to the basic therapy (2B class of recommendations according to the 2020 Russian Society of Cardiology guidelines (RSC) and the 2022 AHA / ACC / HFSA guidelines); • for patients with hypertriglyceridemia (>1.5 mmol/l) as a part of combination therapy (IIb class of recommendations and B level of evidence according to the 2021 European guidelines on cardiovascular disease prevention, etc.); • for adult patients with stage 3-4 chronic kidney disease (CKD), long-chain omega-3 PUFA 2 g/day is recommended for reducing the level of triglycerides (2C class of recommendations). Data on the use of omega-3 PUFA for other indications are heterogenous, which can be partially explained by using different form and doses of the drugs.
Lipid-lowering Eeficacy and Safety of High Doses of Atorvastatin and Rosuvastatin
Authors: Susekov A. V.
Published: March 2023

Administration of high doses of atorvastatin 80 mg/day and rosuvastatin 40 mg/day is a part of a standard algorithm for the treatment of patients at high and very high cardiovascular risk. This treatment allows reducing atherogenic low-density lipoprotein cholesterol (LDL-C) by approximately 50 % and decreasing the risk of cardiovascular diseases. Results of prospective studies with atorvastatin and rosuvastatin demonstrated a significant (45–55 %) decrease in LDL-C and triglycerides (11–50 %). This article focuses on analysis of evidence-based retrospective database for atorvastatin and rosuvastatin in prospective studies; reviewing a retrospective database of the VOYAGER study, including subgroups of patents with type 2 diabetes mellitus or hypertriglyceridemia; evaluation of the variability of the hypolipidemic response; and analysis of the risk for development of cardiovascular diseases and their complications with the statin treatment. Rosuvastatin at the highest daily dose of 40 mg/day was superior to atorvastatin 80 mg/day by the capability for decreasing LDL-C. Both statins showed a great variability in the degree of reducing triglycerides and exerted a minimal effect on high-density lipoprotein cholesterol. According to results of completed studies, rosuvastatin 40 mg/day also was superior to high doses of atorvastatin by tolerability and safety.
Reassessing Constructions in the ARTEMIS Parser
Authors: Cortés Rodríguez Francisco , Mairal Usón Ricardo
Published: March 2023

The aim of this study is to reexamine the status of constructions in ARTEMIS (Automatically Representing TExt Meaning via an Interlingua-based System), a Natural Language Understanding prototype that seeks to provide the syntactic and semantic structure of a given fragment in a natural language. The architecture of ARTEMIS has been designed to conform to the tenets of the Lexical Constructional Model (LCM), a theory in which constructions are a central tool for the linguistic description of languages. However, since ARTEMIS is a computational device, there are many formalization requirements which involve the adaptation of the LCM, a process which necessarily leads to reconsidering several issues, as are: (i) what counts as a constructional structure; (ii) how constructions contribute to parsing operations in ARTEMIS; and (iii) the location and the format of constructional patterns.

Published: March 2023

We report a case of Omenn syndrome due to a novel mutation of the gene DCLRE1C(Artemis). He was referred to our hospital with a complaint of protracted diarrhea, erythematoexfoliative rash, urinary tract infection, pneumonia, and failure to thrive. He was 2 months old. At the first sight, the diagnoses of Omenn syndrome, graft versus host disease (GVHD), Netherton syndrome, and Atopic dermatitis came to mind. Laboratory evaluation showed lymphopenia, eosinophilia, high IgE, and whole-exome sequencing revealed a mutation of the DCLRE1C gene. After obtaining blood samples, he received broad-spectrum antibiotics, antifungals, antiviral, prophylaxis for pneumocystis Jirovecii pneumonia, and Intravenous immunoglobulin. He expired owing to delayed referral and overwhelming sepsis before receiving bone marrow transplantation. In every neonate infant presenting with erythematoexfoliative skin rash, refractory infection, and lymphopenia, Omenn syndrome should be considered.
Bacteriophage Therapy as an Alternative to Antibiotics: A Dead End or A Solution?
Authors: Rismanbaf Amirhossein
Published: March 2023

Antibiotic resistance has been around for years and could lead to a serious crisis in the near future. If the problem of antibiotic resistance is not solved, antimicrobial resistance is predicted to increase, killing 10 million people annually by 2050 (more than the number of cancer deaths), and costing the global economy approximately $100 trillion USD, because of this, it will need the rapid development of alternative therapies. This issue prompted scientists to find a solution; the use of bacteriophages as an alternative to antibiotics is one of these tactics. In this review article, I will first focus on bacteriophages from various aspects and then, by analyzing the available information, I will try to answer the following questions:

Given the meager standard clinical data and characteristics of bacteriophages, is bacteriophage therapy a safe and reliable method?
Given the short time left before the antibiotic resistance crisis, is it cost-effective to invest in bacteriophage?
Are bacteriophages a double-edged sword? (Besides being used to treat bacterial diseases in the future, do bacteriophages have the potential to become a human virus in the future?)

Authors: Sadeghi-Shabestari Mahnaz , Naderpoor Masoud , Farzipour Samira , Dastranji Azar
Published: March 2023

Background: Adenoidal hypertrophy (AH) is a common disorder in pediatric population with severe complications due to nasal air way obstruction. Adenoidectomy is a choice treatment for children with severe symptoms due to AH; however, it is accompanied by several side effects such as complication of surgery and emotional distress. We evaluated the efficacy of intranasal corticosteroid therapy in size and symptoms of Adenoid Hypertrophy especially in atopic patients.
Methods: In this clinical trial 45 children aged 2 to 14 years old with AH were enrolled. All of them underwent 8-week course of intranasal Fluticasone therapy and their symptoms before and after treatment were scored and compared by questionnaires. Also they were divided into Atopic and non- Atopic groups based on history, physical examination and positive skin prick test. Then the two groups were compared after the treatment according to their response to therapy.
Results: After 8 weeks’ treatment with intranasal corticosteroid, improvement in all symptoms score of AH including (Snoring, Sleep Apnea, Mouth breathing and Nasal congestion) was statistically significant (P = 0.000). The improvement in clinical symptoms of AH after treatment was observed in 92% of atopic patients in comparison with non-atopic patients was 50%, which was also statistically significant (P = 0.024).
Conclusion: Our study demonstrated that 8-week intranasal corticosteroid was associated with a decrease in size of AH and all symptoms of obstruction. As a result, it can be suggested that intranasal corticosteroid therapy can prevent adenoidectomy especially in atopic patients.

Introduction: The anterior open bite is a multifactorial malocclusion and a challenge between orthodontists. Based on the origin, divided in two types as dental and skeletal, and appear in the anterior or posterior segments, (unilateral or bilateral). Dental open-bite in the most of patients have environmental etiologic factor such as oral habits, tongue trust, mouth breathing, large tongue. In skeletal type, excessive vertical growth of the maxilla is etiologic factor and accompany with downward-backward rotation of the mandible.Case Report: The case was a 27 years woman with an anterior open bite and unilateral impacted upper canine and congenital missing of lower 2nd premolar in the left side and retained 2nd lower deciduous molar and upper canine in the left side.

The extracted teeth were right lower 2nd premolar and left 2nd deciduous molar and 1st premolars in upper arch. As recommended advancement genioplasty for correction chin deficiency the patient refused it. Conclusion: In this technique we used Orthodontic treatment alone instead of Orthognathic surgery for open bite correction.
Features of Behaviorism in Second Language Acquisition (SLA): An Empirical Excerpt from Applied Linguistics View
Authors: L. Estremera Dr. Michael
Published: March 2023

Three decades thereabouts when Skinner proposed his behaviorist theory in the context of L1 acquisition exploiting sociolinguistic approach specifically. Subsequently, there have been dearth of studies conducted validating the claims of behaviorism in the field of applied linguistics. Thus, RQ1 highlights the principles of behaviorism towards L2 competence with tantamount research assumption. Taking into account the data presented, it reveals that there practically are features of behaviorism which contributed to the successful L2 acquisition by the L2 learners. This involves reward, habit formation as well stimulus-response linguistic processes leading to the acceptance of the first assumption. Reward fosters positive attitude to further explore the unknown. It leads to an affirmative language attitude necessary to discover the full details of the L2 learning. RQ2 delineates the possible linguistic factors that are contributory to the collective L2 performance during the investigation time frame. Primary linguistic factors could have been the minimal L2 exposure of the students to the target language due to transition phase which forced the students to switch codes occasionally to complete the cycle of communication. This study is valuable to the learners and teachers of ESL/EFL worldwide as it offers some pedagogical implications necessary to understand the learning pace, lexical index, comprehensible input (CI), and language attitude of L2 learners. EFL teachers could likewise provide appropriate teaching materials and communicative activities to bring the students to a high level of competence by degrees.

BNCC e suas concepções político-pedagógicas para a educação e educação física: algumas aproximações
Authors: Monteiro Jorge Henrique de Lima , Magalhães Carlos Henrique Ferreira
Published: March 2023

Este artigo tem como objetivo identificar as possíveis teorias pedagógicas que fundamentam o documento BNCC em sua proposta geral e na especificidade da educação física, além das determinações dessas concepções para a prática escolar. As análises ocorreram por meio da técnica de categorização e interpretação hermenêutica-dialética. A partir disso, cogitamos que a BNCC apresenta fortes aproximações com a concepção construtivista de aprendizagem, ao priorizar a construção de capacidades subjetivas, como a busca pelo “aprender a aprender”, “ser autônomo” e “protagonista”. Para a especificidade da educação física, identificamos a relação com a teoria crítico-emancipatória, ao objetivar o desenvolvimento de competências e com a utilização do termo “cultura corporal de movimento”, ao considerar os elementos constitutivos da educação física. Assim, concluímos que o documento BNCC prioriza o desenvolvimento da sociedade, a partir da construção de sujeitos flexíveis, individualistas e (in)capazes de alterar sua realidade, determinando um processo de esvaziamento de conteúdo a ser apropriado historicamente pelos alunos, sendo isso a materialização atual de um movimento iniciado na década de 1990, com políticas neoliberais, pós-modernas e neoconservadoras.

Published: March 2023

As experiências sociorrelacionais promovidas no ambiente escolar e o modo como podem mobilizar a subjetividade de estudantes com deficiência intelectual, contribuindo para a aprendizagem escolar, instituíram o propósito deste artigo. A pesquisa teve aporte teórico na perspectiva histórico-cultural do desenvolvimento humano, a partir das contribuições de Vygotsky em relação à defectologia, e na teoria da subjetividade, desenvolvida por González Rey. Por meio da metodologia construtivo-interpretativa realizou-se a pesquisa com duas participantes do terceiro ano do ensino fundamental em classe inclusiva de uma escola pública do Distrito Federal. A produção das informações ocorreu em um projeto de pesquisa-ação e contou com instrumentos favorecedores da expressão das participantes, como dinâmicas conversacionais, recursos imagéticos e caderno de memórias. Mediante o processo interpretativo das informações, reconhecemos que a qualidade das experiências sociorrelacionais no contexto escolar podem promover algum nível de emergência do sujeito em estudantes com deficiência intelectual como expressão do movimento da subjetividade, possibilitando a mobilização da aprendizagem escolar.

Buscou-se identificar e relacionar as ocorrências de violência que envolvem estudantes e professores, as estratégias utilizadas por esses professores para o enfrentamento do bullying e as suas crenças e percepção de autoeficácia para intervir nesse problema. Em estudo transversal, com abordagem analítica, realizado em 2018, com 46 professores de Guaiúba, Ceará, Brasil, foram aplicados três questionários para investigação da violência escolar e das práticas, crenças e percepção de autoeficácia dos docentes diante do bullying. Os dados foram analisados por meio de estatística descritiva e inferencial. Identificou-se que existe prevalência significativa de violências que envolvem professores e estudantes nas escolas investigadas. Professores que foram autores de bullying na infância concordam mais com crenças normativas (p=0,04) e de aprendizagem (p=0,03), enquanto professores que foram vítimas acreditam que as estratégias de esquiva são inadequadas (p=0,02). Portanto, é necessária a identificação das percepções, crenças e do histórico de envolvimento em bullying de professores para a construção de programas mais eficazes de enfrentamento da violência escolar.
Discourses regarding the sustainability and environmental considerations in physical planning of second homes in Norwegian mountain destinations: a comparison between governmental documents, research literature and the general media
Authors: Tjørve Even , Tjørve Kathleen M. C.
Published: March 2023

The neoliberal trend in spatial planning seemingly causes the loss of control of spatial plans for destination developments in the mountain regions of southern Norway. The predominant local discourse, as seen in local newspapers and other media, was originally positive to the development of second homes. Changes in development plans have, as in the Skeikampen-destination case, incited strong counter-discourses based on concerns for pasture rights, nature values, and access, in addition to sustainability in general. These discourses create a perception of reality in stark contrast to the central- government discourse, as found in the plan and building act, and governmental documents.
Towards a sustainable management model of the “Festa dos Tabuleiros”

Published: March 2023

The key goal of this conceptual paper is the creation of a sustainable management model of the Festa dos Tabuleiros (FT) event that provides a quality experience to the visitors without threatening the social, cultural and environmental integrity of the territory. Action research methodology has been used to improve the way the Tomar municipality organises and promotes the FT. In order to establish this model, it is necessary to determine the agents and relationships that underlie the production system of this event, aiming to improve the quality of its offer and the experience it provides to visitors as well as the sustainability of its production and consumption processes. In this sense, the development of the model will be based on four tasks: (1) stock-taking, interpreting and exhibiting cultural resources; (2) identifying, involving, analysing and educating stakeholders; (3) benchmarking of good practices in event sustainability; and (4) managing and monitoring the model. Hence, this paper aims to contribute to the safeguarding of the FT and to the sustainable development of the municipality and the region. This intent is achieved through the creation of a sustainable tourist-cultural management model that promotes the study, protection, enhancement, and dissemination of this event, as well as the creation of efficient and innovative solutions in an integrated way.
Effets de la dose et fractionnement de l'azote sur l'acidité d'un Histosol et le rendement en riziculture
Authors: Soro Nahoua Christophe , Koné Brahima , Soumaila Yeo
Published: March 2023

L’azote est indispensable en riziculture alors que la fertilisation azotée est soumise à des pertes en milieu inondé. Elle peut modifier l’acidité du sol tendant à une dégradation des sols et une faible efficience agronomique. C’est pourquoi, la gestion de la fertilisation azotée doit être rationnelle spécialement sur Histosol (tourbe) qui mérite préservation. C’est dans un tel contexte que cette étude a été réalisée pour identifier l’interaction optimale de la dose (0, 80, 100, 120 kg ha-1) et du fractionnement (0, 1, 2, 3 et 4) de l’azote dans un dispositif split-plot utilisant la variété de riz WITA9. La dose d’azote a eu des effets significatifs (P<0,05) sur le rendement en grain (RDG) du riz et le pH du sol. Un parallélisme a été noté pour les courbes de tendance du pHeau et du RDG permettant d’identifier la dose l’optimal à 80 kg N ha-1 pour le RDG (5,1 t ha-1) et le pH (4,6). Aussi, 4 fractions de la dose ont été meilleures selon l’efficience agronomique. Une régression du pH selon le nombre de fraction de l’azote a permis de prédire 5 fractions comme l’optimale pour le pH (4,8) du sol. La dose 80 kg N ha-1 appliquée en cinq fractions a été recommandée pour une riziculture durable, spécialement sur Histosol.

Rapid human population growth, increased demand for land, overexploitation and the degradation of local natural resources have led to serious socio-economic and environmental challenges in Machakos County, Kenya, East Africa. This has led to a drastic reduction in tree cover in arid and semiarid areas over the years. To reverse this trend it is important to understand the socio-economic factors that determine household tree planting and cover retention in Machakos County. Based on a structured questionnaire targeting 412 respondents as well as focus group discussions and key informants, we assessed the determinants of tree planting cover retention using a logistic regression model. The study found that socioeconomic variables that significantly influenced tree cover adoption in Machakos County in Kenya included gender (p=0.011), household size (p=0.030), and title deed ownership (p=0.023). The respondents used tree products to enhance their socio-economic resilience. In total, 58 different types of tree species were planted or retained on the farms. The major tree species included Eucalyptus saligna, Grevillea robusta, Mangifera indica, Persea americana, Croton megalocarpus, and Terminalia brownie. Based on our findings we recommend more involvement of women and youth in tree planting activities in Matungulu Sub-county.

Published: March 2023

The present paper attempts to find the impact of the rural infrastructural facilities on agricultural growth in India. It analyzes the trends in rural infrastructure variables and value of output from agriculture sector over the study period 1990-19 to 2017-18. Compound annual growth rates (CAGR) have been worked out to find the changes in area, production and yield of agriculture output. To investigate the relationship between infrastructure variables and value of agricultural output the regression analysis has been used. In present study the rural infrastructure includes irrigation facilities, fertilizer consumption, primary agricultural credit societies, electric supply, agricultural markets, and road network in rural areas. Study finds that there is significant impact of irrigation, fertilizer consumption, credit, regulated agricultural markets and road infrastructure on agricultural output. The impact of electric pump, tractors and village electrification has not found statistically significant. It implies that infrastructure facility like roads, irrigation and electricity have a more direct effect on agriculture growth than personal infrastructure like electrical pumps and tractors. This finding validates the conclusion regarding positive and significant relationship between rural infrastructure and agriculture growth in India.

L’utilisation des déchets urbains comme fertilisants organiques peut être à l’origine d’une contamination du sol en éléments traces métalliques. Le maïs, l’une des céréales les plus consommées au Burkina Faso, pourrait accumuler ces éléments toxiques et provoquer des problèmes sanitaires à l’homme à travers leur consommation. Pour évaluer le potentiel de translocation du maïs, un essai est mis en place dans le périmètre maraicher de Sakabi, dans la commune de Bobo Dioulasso. Pour ce faire, des parcelles ont été confectionnées et organisées selon un dispositif en bloc complètement randomisé avec six répétitions. Des doses croissantes de 20, 40 et 60 tonnes de déchet par hectare ont été apportées dans les différentes parcelles pour constituer les traitements. Les échantillons de sol et la biomasse végétale ont été prélevés pour déterminer les teneurs en éléments traces métalliques. Les résultats des analyses montrent que les sols sont contaminés en métaux lourds et ont contribué à la translocation de ces derniers dans les différents organes du maïs. Les facteurs de translocation sont supérieurs à 1 dans tous les organes exception faite pour les tiges donc les valeurs sont comprises entre 0,5-0,8 et 0,76-0,93 respectivement pour le cadmium et le cuivre. En outre la corrélation de Pearson a montré une forte relation entre les teneurs en métaux lourds dans les différents organes. Lorsque le cadmium dans le sol augmente de 1 mg il y a une forte probabilité qu’il augmente de 0,22 mg dans les racines, 1,33 mg dans les tiges, 0, 31 mg dans les feuilles et 0,56 mg dans les grains. De même, au niveau du cuivre, il peut augmenter de 2,56 mg, 0,28 mg, 0,57 mg respectivement pour les racines, tiges et feuilles pour une augmentation de 1 mg de Cu dans le sol. Au niveau du plomb, il y a une forte probabilité que les teneurs dans les feuilles et dans les grains augmentent respectivement de 6,84 mg et 5,81 mg pour une augmentation de 1 mg de plomb dans le sol. Pour le cas du zinc, il peut augmenter de 0,61 mg, 0,17 mg, 0,15 mg respectivement pour les tiges, feuilles et grains pour une augmentation de 1 mg dans le sol.
Effet in Vitro des Extraits d’Algues [Sargassum natans (Børgesen) Børgesen et Sargassum fluitans (Børgesen) Børgesen, Sargassaceae] sur le Fusarium, Agent Pathogène de la Fusariose asculaire de la Tomate (Solanum lycopersicum L., Solanaceae)

La tomate occupe une place très importante dans la vie socio-économique de la population ivoirienne. Elle est une source importante de revenus pour les producteurs. Cependant, Fusarium sp. est parmi les champignons telluriques les plus agressifs causant la maladie de la fusariose chez la tomate. Pour lutter contre ce pathogène les agriculteurs utilisent généralement des méthodes de lutte chimique. Cette lutte n’est pas sans effet secondaire. Elle a des répercussions sur la santé humaine et animale ainsi que sur l’environnement. Afin d’assurer une meilleure production, de réduire l’incidence et la sévérité des maladies de la tomate particulièrement de la fusariose vasculaire en Côte d’Ivoire et de protéger l’environnement et la santé des populations, des bio-fongicides à base des extraits d’algues Sargassum natans et Sargassum fluitans ont été testés in vitro sur la croissance mycélienne de Fusarium sp. Un échantillonnage d’organes de tomate symptomatiques dans la localité de Songon suivi d’isolement au laboratoire ont permis d’obtenir des souches de Fusarium sp. Des tests d’inhibition de la croissance mycélienne par les bio-fongicides Callifert spécial maraichage et le mélange des extraits d’algues à l’adjuvant Cawet max se sont avérés efficaces, avec un taux d’inhibition de 100 % aux concentrations de 20 et 30 %. Par contre, l’extrait d’algues seul s’est montré moins efficace à la concentration 30 %.
Cartografía social participativa como metodología de investigación territorial
Authors: Bonfá Neto Dorival , Suzuki Júlio César
Published: March 2023

La cartografía social participativa contribuye con la comprensión de los referentes constituidos por los sujetos, así como los significados que los constituyen sobre todo desde sus relaciones con el territorio. Así, durante el trabajo de campo centrado en las actividades de pesca artesanal, a partir de talleres participativos con alumnos de la escuela municipal de Bahía Solano (Chocó, Colombia), con debates, elaboración de mapas y entrevistas, se busca analizar la construcción del territorio y las territorialidades tradicionales afrocolombianas en el Pacífico, a partir de su relación con prácticas y conocimientos tradicionales involucrados sobre todo con la pesca, a menudo ocultos en mapas oficiales. Se advirtió, entonces, que las visiones y los mapas construidos por niños y jóvenes, entre 13 y 18 años, de la comunidad pesquera de Bahía Solano revelaron la conciencia social y cultural de estos sujetos, pues en gran medida perciben muchas de las territorialidades en las que se insertan y la relación con las actividades tradicionales.

Remote sensing is a cost-effective method to monitor soil health. Compared with conventional monitoring station networks, it has improved spatial representativeness and no interference with farming activities. For the last few decades, microwave remote sensing has been tested on satellites for global soil moisture monitoring. A number of experimental and theoretical studies were conducted to further develop both active and passive microwave soil moisture remote sensing techniques at regional and farm scales. The recent development shows the potential of regular soil moisture remote sensing with a high resolution and high accuracy. In the future, P-band soil moisture remote sensing, deep learning, UAV techniques are expected to have a high sensitivity and high-resolution soil moisture at the farm scale.

Numerous studies referred to in this book and in other publications have examined the relationship between a proximal sensor, or remote sensing with crop yield and other attributes of interest to precision agriculture. Combining data from two or more sensors tends to increase the relationship between sensor readings and crop attributes. Crop canopy height, active-optical sensor readings, remote sensing data, and weather data have been combined to increase predictability of crop attributes. The fusion of these data requires the use of appropriate statistical tools. Description of several of these tools is provided in this chapter.
