Abstract:
ABSTRACT The efficacy of some bio-rational insecticides against tea looper complex, Hyposidra spp. was evaluated at two different locations of Dooars tea plantations, West Bengal. The results indicated that all the insecticides were effective in reducing the looper population to a significant level. However, in comparison to other insecticides, neem based insecticides could not give the desired level of control. Among the different treatments, diflubenzuron 25 WP @ 700g/ha caused maximum reduction of loopers over control in both the sprayings at both the locations [Location I: 66.91% and 65.54% reduction of loopers at 7 days after 1st and 2nd spraying respectively) and Location II: 68% and 50.85% reduction of loopers at 7 days after 1st and 2nd spraying respectively)] and appeared to be the best treatment against loopers. Bt-k @ 1000 mL/ha was the next best treatment for suppressing looper population at 7 days after 1st spraying (64.44% and 67.81% reduction of loopers at Location I and II respectively) which was at par with recommended insecticide deltamethrin 2.8 EC @ 200 mL/ha (65.14% and 62.16% reduction of loopers at Location I and II respectively). However, in 2nd spraying, its efficacy was declined. Both the doses of Neem based insecticides recorded 31-49% reduction of loopers after 1st spraying but this was reduced only to 9-17% after 2nd spraying, Thus, in consideration of the performance of the insecticides, diflubenzuron @700 g/ha and Bt-k @ 1000 mL/ha could be included in the IPM package of looper.

Abstract:
ABSTRACT Caterpillars of three major geometrid species such as, Hyposidra talaca, H. infixaria and Buzura suppressaria frequently attack tea plantations of sub-Himalayan plains of Terai and the Dooars region. The feeding activity of these pests often leads to heavy defoliation of tea bushes almost throughout the year. A clear understanding of the morphological diversity of these sympatric species is necessary at all life stages in order to contemplate their management strategies. Field observations indicated that amongst the loopers there is a dominance of H. talaca and H. infixaria at different seasons compared to the third species, B. suppressaria. Although a clear morphological difference of the adult moths of three concerned species was evident along with their distinct morphometry and weights, the larval instars of the congeners of Hyposidra were difficult to distinguish. However, a significant difference was observed in their development periods, which were 55 days for H. talaca and 48 days for H. infixaria. A clear distinction of the concerned species based on morphometrics and weight of pupa was also evident. In recent past, loopers have assumed the status of severe pest of tea in the sub- Himalayan plains mainly due to invasion of the two species of Hyposidra that have joined B. suppressaria in sharing the tea leaves as their ideal host. The newer pest species of Hyposidra otherwise known to occur on forest and fruit plants have of late turned to be a major defoliator of tea.

Abstract:
This study was carried out in eight districts of Nepal to explore the pests, pesticides and other agro-chemicals used in high value crops viz. tea, coffee, honey and vegetables (tomato and brinjal). The study carried out districts for tea were Jhapa and Illam, whereas for vegetables Bara and Kavre. Similarly, honey was studied in Chitwan and Nawalparasi, whereas coffee in Gulmi and Lalitpur. The results revealed that different type of pests were found to be problematic in high value crops production. Loopers were the major pests in tea, borers in coffee, fruit fly in vegetables and mites in beekeeping. Different pesticides and some other agro-chemicals have been found to be used for pest management. Additionally, pesticide residues analysis for selected pesticides was carried out using GC-MS technique. The result of analysis showed that non of pesticides was found at the detection level of 0.7 parts per million. DOI: http://dx.doi.org/10.3126/jfstn.v7i0.10608 J. Food Sci. Technol.

Abstract:
The main objective of the present study was to meticulously document the non-chemical approaches to tea pest management employed by small tea growers in the Dibrugarh and Tinsukia districts of Assam. In response to the constraints imposed by the COVID-19 pandemic, the research team resorted to telephonic interviews, utilizing a well-structured questionnaire to gather information from these tea growers. Through this method, the study successfully captured and documented the specific practices, materials, techniques, and methods utilized by these growers in their ongoing battle against tea pests. The study brought to light a diverse array of non-chemical methods that have been embraced by tea growers in this region. These practices, deeply rooted in traditional knowledge, demonstrated their remarkable effectiveness in pest management. What makes these findings particularly significant is the potential they hold for future scientific investigations. These traditional techniques, when subjected to rigorous validation and refinement, could find broader application in large-scale tea pest management initiatives, offering a more sustainable and eco-friendlier alternative to conventional chemical methods. A noteworthy aspect of these non-chemical practices is the sourcing of ingredients. These materials were found to be locally available and abundant, derived from both plant and animal origins. This accessibility not only ensures the practicality of these methods but also highlights their compatibility with the local ecosystem. Importantly, these traditional practices were identified as crucial tools in combating infestations by various pests, including the red spider mite (Oligonychus coffeae), tea mosquito bug (Helopeltis theivora), and looper caterpillar (Buzura suppresseria). In conclusion, this study focused on the valuable task of gathering insights into the non-chemical pest management methods practiced by small tea growers in the Dibrugarh and Tinsukia districts of Assam. Despite the adversities posed by the pandemic, the telephonic interviews proved to be a robust means of collecting invaluable information about these practices. The study not only underscored the efficacy of these traditional methods but also emphasized their potential for further scientific exploration and subsequent integration into broader tea pest management strategies. This presents a promising and environmentally friendly path forward for the tea industry in this region and beyond.

Abstract:
The study was undertaken on insect, mite and nematode species diversity in Bangladesh Tea Research Institute (BTRI) main farm, Baraoora and Phulcherra tea estates in Sreemangal, Bangladesh from the period of 2014 to 2015. The study was done through direct field observations, sweeping net, food trap, sticky trap, light trap and Baermann Funnel method. A total of 71 insect, mite and nematode species was recorded belonging to 45 families under 14 orders. Among these, 25.35% species were foliar insects and mites, 26.76% soil insects and nematodes, 21.13% beneficial insects and 26.76% butterflies. All the foliar and soil insects, mites and nematodes were found as recognized pests of tea. The highest number of individuals among foliar pest was the red spider mite (Oligonychus coffeae) and the lowest number was the coffee red borer (Zeuzera coffeae). Of the soil pests, 77.47% species were termites, 14.33% nematodes, 4.86% field cricket, 2.63% mole cricket and 0.72% cockchafer grub. Regarding the soil pests, live wood termite (Microtermes obesi) was the highest and dagger nematode (Xiphinema sp.) was the lowest in number. One species of foliar insect, looper caterpillar (Hyposidra infixaria) and three species of nematodes, viz. reniform nematode (Rotylenchulus sp.), ring nematode (Criconemoides sp.) and dagger nematode (Xiphinema sp.) were recorded for the first time as tea pest in Bangladesh. In case of beneficial insects, 81.49% species were predators, 16.73% parasitoids and 1.78% parasites. Lady bird beetle (Micraspis discolor) was the highest in number and anthocorids (Anthocoris sp.) were the lowest. Nineteen species of butterflies were found. Of the observed butterflies, lemon emigrant (Catopsilia pomona) was the highest and large oakblue (Arhopala amantes) was the lowest in number. According to pest status, tea mosquito bug, red spider mite, thrips, looper caterpillar, live wood termites, root knot nematode and root lesion nematode were major, and the rest of those were occasionally regarded as minor pest. The population of most of the pest species was higher in peak cropping season (April-November), whereas the lowest population was recorded in off season (December-February). According to diversity indices, the diversity of foliar pest was higher than the other groups and the foliar pest was more evenly distributed in comparison to soil, beneficial insects and butterflies.J.

Abstract:
Considering classical open string solutions with a null polygonal contour at the boundary of AdS3, the geometric problem of minimal surfaces related to gluon scattering amplitudes at strong coupling is developed and solved in a set of TBA-like integral equations. Their form resembles that of a TBA system whose free energy yields the dynamic contribution to the area. The corresponding set of functional relations, the so called Y-system, is derived and extensively analyzed in the cases of octagon and decagon together with the set of integral equations. Useful rewrites of the latter establish the connection with a particular class of HSG models and allow us to identify their Y-system (related to a universal TBA) with the one derived in AdS3 when the algebra level k is set to 2. A useful insight that clarifies how to properly reduce to the An series is offered. Thanks to a well defined change of reference frame, whose mathematical structure has been studied in detail, the dynamic part of the remainder function coincides with the extremum of the Yang-Yang functional for the modified TBA equations. Explicit examples have been treated in terms of Y-functions and pseudo-energies, extrapolating useful links with several works concerning null WLs, Hitchin systems and integrable perturbations of CFTs corresponding to Gk-parafermions.

Abstract:
Nous nous intéressons aux lacets markoviens définis dans le cadre de la théorie des chaînes de Markov à temps continu sur un espace d'états discret. Ce sujet a notamment été étudié par Le Jan [LJ11] et Sznitman [Szn12]. En contraste avec ces références, nous ne supposerons pas la symétrie de la chaîne et nous intéresserons plutôt au cas infini. Tous les résultats sont présentés en termes de générateur de semi-groupe. En comparaison avec [LJ11], certaines preuves ont été détaillées ou améliorées.Nous fournissons par ailleurs quelques résultats sur les amas de boucles (voir [LJL12] dans le cas symétrique). Nous traitons notamment l'exemple du cercle discret. Nous étudions aussi les arbres couvrants définit par l'algorithme de Wilson dans le cas asymétrique.Dans la dernière partie, nous considérons la proportion des lacets couvrants l'espace. En utilisant la limite du spectre, nous donnons une expression générale de la limite de cette proportion pour une suite de graphes. Comme une application, nous donnons deux exemples concrets dans lesquels une transition de phase apparaît.

Abstract:
In this thesis, we present a Thread-Level Speculation (TLS) framework whose main feature is to speculatively parallelize a sequential loop nest in various ways, to maximize performance. We perform code transformations by applying the polyhedral model that we adapted for speculative and runtime code parallelization. For this purpose, we designed a parallel code pattern which is patched by our runtime system according to the profiling information collected on some execution samples. We show on several benchmarks that our framework yields good performance on codes which could not be handled efficiently by previously proposed TLS systems.

Abstract:
E calcul autonome vise à concevoir des logiciels qui prennent en compte les variations dans leur environnement d'exécution. Les boucles de rétro-action (FCL) fournissent un mécanisme d'auto-adaptation générique, mais leur intégration dans des systèmes logiciels soulève de nombreux défis. Cette thèse s'attaque au défi d'intégration, c.à.d. la composition de l'architecture de connexion reliant le système logiciel adaptable au moteur d'adaptation. Nous proposons pour cela le langage de modélisation spécifique au domaine FCDL. Il élève le niveau d'abstraction des FCLs, permettant l'analyse automatique et la synthèse du code. Ce langage est capable de composition, de distribution et de réflexivité, permettant la coordination de plusieurs boucles de rétro-action distribuées et utilisant des mécanismes de contrôle variés. Son utilisation est facilitée par l'environnement de modélisation ACTRESS qui permet la modélisation, la vérification et la génération du code. La pertinence de notre approche est illustrée à travers trois scénarios d'adaptation réels construits de bout en bout. Nous considérons ensuite la manipulation de modèles comme moyen d'implanter ACTRESS. Nous proposons un Langage Spécifique au Domaine interne qui utilise Scala pour implanter une famille de DSLs. Il permet la vérification de cohérence et les transformations de modèles. Les DSLs résultant ont des propriétés similaires aux approches existantes, mais bénéficient en plus de la souplesse, de la performance et de l'outillage associés à Scala. Nous concluons avec des pistes de recherche découlant de l'application de l'IDM au domaine du calcul autonome.

Abstract:
Les applications de flux de données sont des cibles importantes de l'optimisation de programme en raison de leur haute exigence de calcul et la diversité de leurs domaines d'application: communication, systèmes embarqués, multimédia, etc. L'un des problèmes les plus importants et difficiles dans la conception des langages de programmation destinés à ce genre d'applications est comment les ordonnancer à grain fin à fin d'exploiter les ressources disponibles de la machine.Dans cette thèse on propose un "framework" pour l'ordonnancement à grain fin des applications de flux de données et des boucles imbriquées en général. Premièrement on essaye de paralléliser le nombre maximum de boucles en appliquant le pipeline logiciel. Après on merge le prologue et l'épilogue de chaque boucle (phase) parallélisée pour éviter l'augmentation de la taille du code. Ce processus est un pipeline multidimensionnel, quelques occurrences (ou instructions) sont décalées par des iterations de la boucle interne et d'autres occurrences (instructions) par des iterationsde la boucle externe. Les expériences montrent que l'application de cette technique permet l'amélioration des performances, extraction du parallélisme sans augmenter la taille du code, à la fois dans le cas des applications de flux des donnée et des boucles imbriquées en général.

Abstract:
Les Robots Parallèles à Câbles (RPC) sont considérés comme des manipulateurs parallèles avec des câbles flexibles au lieu de liens rigides. Un RPC se compose d'un bâti, d'une plate-forme mobile et de câbles les reliant l'un à l'autre. Les RPC sont réputés pour leurs performances avantageuses par rapport aux robots parallèles classiques en termes d’espace de travail en translation, de reconfigurabilité, de capacité de charge utile importante et de performances dynamiques élevées. Cependant, l'amplitude de rotation de la plateforme mobile des RPC est généralement limitée en raison des collisions de types câble/câble et câble/plateforme mobile. L'objectif de cette thèse est ainsi de concevoir, d'analyser et de prototyper des RPC hybrides ayant à la fois un grand espace de travail en translation et un grand espace de travail en orientation en utilisant des boucles de câbles. Ce travail de recherche présente le développement de trois RPC hybrides adaptés aux tâches nécessitant de grands espaces de travail en orientation et en translation comme le balayage tomographique, les dispositifs d'orientation de caméras et l'inspection
Cable-Driven Parallel Robots (CDPRs) also noted as wire-driven robots are parallel manipulators with flexible cables instead of rigid links. A CDPR consists of a base frame, a moving-platform and a set of cables connecting the moving-platform to the base frame. CDPRs are well-known for their advantageous performance over classical parallel robots in terms of translation workspace, reconfigurability, payload capacity and high dynamic performance. However, most of the CDPRs provide limited amplitudes of rotation of the moving-platform due to cable/cable and cable/moving-platform collisions. The objective of this thesis is to design, analyze and build hybrid CDPRs to enlarge the orientation workspace in addition to their large translation workspace by exploiting cableloops. This research work presents development of three hybrid CDPRs with drastically augmented orientation workspace suitable for tasks requiring large orientation and translational workspaces like tomography scanning, camera-orienting devices, visual surveillance and inspection

Full text
Abstract:
Le but initial de cette thèse était d'étudier les espaces de superlacets, version géométrique des espaces de supercordes en Physique. Le point de départ était alors d'étendre les résultats de classifications de l'article de Oleg Mokhov : Symplectic and Poisson structures on loop spaces of smooth manifolds, and integrable systems au cadre de la supergéométrie. Dans cet article l'auteur établit une classification des formes symplectiques locales homogènes d'ordre 0, 1 et 2 sur l'espace des lacets LM = C1(S1;M) à partir d'objets géométriques sur la variété différentiable M. Dans cette thèse, on remplace la variété M par une supervariété Mpjq et le cercle S1 par un supercercle S1jn et l'on étudie l'espace des morphismes de supervariétésMor(S1jn;Mpjq). Dans les deux premières parties, l'on définit les structures géométriques classiques et super des espaces de superlacets. Pour ce faire, l'on se restreint aux deux supercercles S1j1 et en s'inspirant des travaux sur LM, l'on détermine une structure de variété de Fréchet des espaces de superlacets SLM = Mor(S1j1;M). Puis l'on introduit la structure super qui nous a semblé la plus naturelle sur SLM en terme de faisceaux. Afin de pouvoir travailler en coordonnées, l'on introduit la structure super par un autre point de vue en considérant l'espace de superlacets SLM comme le foncteur de points SLM. De plus, en interprétant les calculs de Mokhov en terme de jets, ceci nous permet d'une part d'apporter une justification rigoureuse aux-dits calculs et d'autre part, d'obtenir une généralisation directe des méthodes de calculs en coordonnées ("à la physicienne"). Le troisième chapitre expose les résultats de classification obtenus. Comme dans le cas classique, on obtient un théorème de dépendance limitée de l'ordre des jets qui interviennent dans les formes d'ordre 0 et 1. Puis, on obtient une classification des formes d'ordre 0 au moyen de formes différentielles sur la supervariété Mpjq. Une classification des formes homogènes d'ordre 1 et 2 au moyen de métriques Riemaniennes et de connexions sur Mpjq. Enfin le quatrième chapitre est consacré à la généralisation des résultats d'un autre article de O. Mokhov : Complex homogeneous forms on loop spaces of smooth manifolds and their cohomology groups. De par la présence de la variable impaire, on précise tout d'abord la définition des formes homogènes locales sur SLM, puis on démontre que muni de la différentielle extérieure, l'espace des formes homogènes sur SLM d'ordre m 2 N donné définit un complexe. On calcule alors complètement les espaces de cohomologie pour les ordres m = 0 et 1, partiellement pour les ordres 2 et 3 et on explicite ainsi les formes symplectiques exactes obtenues au troisième chapitre.

Full text
Abstract:
Cette thèse s'articule autour des espaces de modules de représentations de carquois arbitraires, c'est-à-dire possédant d'éventuelles boucles. Nous obtenons trois types de résultats. Le premier concerne la base canonique de Lusztig, dont la définition est étendue à notre cadre, notamment en introduisant une algèbre de Hopf généralisant les groupes quantiques usuels (i.e. associés aux algèbres de Kac-Moody symétriques). On démontre au passage une conjecture faite par Lusztig en 1993, portant sur la catégorie de faisceaux pervers qu'il définit sur les variétés de représentations de carquois.Le second type de résultats, également inspiré par le travail de Lusztig, concerne la base semi- canonique et la variété Lagrangienne nilpotent de Lusztig. Pour un carquois arbitraire, on définit des sous-variétés de représentations semi-nilpotentes Λ(α), et nous montrons qu'elles sont Lagrangiennes. La démonstration repose sur l'existence de fibrations affines partielles entre diverses composantes de Λ(α), contrôlées par une combinatoire précise. Nous définissons une algèbre de convolution de fonctions constructibles sur ⊔Λ(α), et montrons qu'elle possède une base formée de fonctions quasi- caractéristiques des composantes irréductibles des Λ(α). La structure combinatoire qui se dégage ici est analogue à celle obtenue sur les faisceaux pervers de Lusztig, et fait apparaître des opérateurs plus généraux que ceux décrits par les cristaux de Kashiwara.Le troisième thème considéré est celui des variétés carquois de Nakajima, dont l'étude géomé- trique menée ici permet, conjointement avec ce qui est fait précédemment, de donner une définition de cristaux de Kashiwara généralisés. On définit à nouveau des sous-variétés Lagrangiennes, ainsi qu'un produit tensoriel sur leurs composantes irréductibles, comme fait dans le cas classique par Nakajima.

Abstract:
Oxides form a class of material which covers almost all the spectra of functionalities : dielectricity, semiconductivity, metallicity superconductivity, non-linear optics, acoustics, piezoelectricity, ferroelectricity, ferromagnetism...In this thesis, crystalline oxides have beenintegrated on the workhorse of the semiconductor industry, the silicon, by Molecular Beam Epitaxy (MBE).The first great interest of the epitaxial growth of crystalline oxides on silicon consists in the application of "high-k" dielectric for future sub-22nm CMOS technology. Gadoliniumoxide was explored in detail as a promising candidate of the alternative of SiO2. The pseudomorphic epitaxial growth of Gd2O3 on Si (111) was realized by identifying the optimal growth conditions. The Gd2O3 films show good dielectric properties and particularly an EOTof 0.73nm with a leakage current consistent with the requirements of ITRS for the sub-22nmnodes. In addition, the dielectric behavior of Gd2O3 thin films was further improved by performing PDA treatments. The second research interest on crystalline oxide/Si platform results from its potential application for the "More than Moore" and "Heterogeneous integration" technologies. TheSrTiO3/Si (001) was intensively studied as a paradigm of the integration of oxides on semiconductors. The crystallinity, interface and surface qualities and relaxation process of the STO films on silicon grown at the optimal conditions were investigated and analyzed. Several optimized growth processes were carried out and compared. Finally a "substrate-like" STO thin film was obtained on the silicon substrate with good crystallinity and atomic flat surface. Based on the Gd2O3/Si and SrTiO3/Si templates, diverse functionalities were integrated on the silicon substrate, such as ferro-(piezo-)electricity (BaTiO3, PZT and PMN-PT),ferromagnetism (LSMO) and optoelectronics (Ge). These functional materials epitaxially grown on Si can be widely used for storage memories, lasers and solar cells, etc.

Nous montrons que la mesure des fluctuations thermiques des ressorts permet de déterminer précisément leur raideur à condition d'utiliser un modèle qui prend en compte la forme des modes et la méthode de détection. A l'aide de nouvelle méthodes d'analyse des courbes de rétraction, nous étudions la conformation de polymères et de copolymères adsorbés, ainsi que l'interaction spécifique entre un complexe du nickel (Ni-NTA) et l'acide aminé histidine. Nous mettons en évidence des comportements inattendus en présence de liens multiples et nous en proposons une interprétation basée sur un équilibre entre formations et ruptures des liaisons. Nous présentons des premiers résultats expérimentaux concernant la transition conformationnelle de la polylysine sous étirement.

Abstract:
This concluding chapter brings together the evidence gathered in the ten case studies. It concentrates on two key questions. First, what ignites growth within a country? Then once growth is ignited how is it maintained? The framework highlights that how the political settlement and rent space interact determines the deals space in which elites operate. Feedback loops, both positive and negative, exist within the case studies analysed. Transnational factors such as commodity price movements on international markets, the role of foreign donors, foreign direct investment, and neighbourhood effects can all have a significant impact on transitions between growth episodes. Implications for development policy are considered.

Abstract:
Now fully revised and updated with the latest imaging techniques and technology and covering even more conditions than before, this new edition of The ESC Textbook of Cardiovascular Imaging provides extensive coverage of all cardiovascular imaging modalities, and is produced in collaboration with the European Association of Cardiovascular Imaging with contributions from specialists across the globe and edited by a distinguished team of experts. It not only discusses the principles of individual modalities but also clearly demonstrates the added value each technique can bring to the treatment of all cardiac diseases. Richly illustrated with colour figures, images, and tables and using a wealth of newly available evidence to link theory to practice, it demonstrates how these techniques can be used in the diagnosis of a range of cardiovascular diseases. Learning how to apply them in practice is made easy with videos and imaging loops online, and it contains information on cutting-edge technical developments in echocardiography, CT, CMR and hybrid imaging, as well as imaging's current role in cardiac interventions, such as identifying cardiac structures, helping to guide procedures and exclude possible complications. The application of imaging modalities in conditions such as valvular and coronary heart disease, heart failure, cardiomyopathies, peri-myocardial disease, adult congenital heart disease and aortic disease, is also extensively considered.

Abstract:
AbstractHere we turn to the strategies that young people use to prevent chemical harms, not just those related to single chemicals but also those related to the feedback loops and compounding effects generated by the multiplicity of chemicals in daily life. Chemical Futures takes as an example youth activists in France, the Générations Cobayes, and their mobilization against endocrine-disrupting chemicals. We examine what contributes to the relative invisibility of toxic risk, pointing especially to the role of corporations in generating uncertainty about scientific evidence. The ChemicalYouth project engaged in a range of collaborative, youth-led projects that demonstrate the many ways youth may be engaged in “harm reduction from below.” We suggest that a ChemicalYouth 2.0 project might involve a wider range of researchers, advisors, and laboratories, to make more visible the multiple toxicities that make up young people’s everyday lives. Finally, we argue that governments should team up with youth and complement their efforts with “harm reduction from above” initiatives to regulate unsafe chemicals and support youths’ efforts to observe the effects of chemicals on their bodies and share information with others.

Abstract:
AbstractIn light of the escalating pace and heightened intensity of contemporary climate change and human interventions, a more systematic and comprehensive approach to research has become imperative for the realization of the Sustainable Development Goals (SDGs) within dryland regions. In 2017, a collaborative research consortium comprising experts from diverse nations proposed the Global Dryland Ecosystem Programme (Global-DEP). This initiative was designed to address the intricate challenges inherent in the diverse and fragile social-ecological systems (SESs) of drylands. Drawing from a synthesis of preceding studies on dryland SESs and insights garnered from extensive regional consultations, the consortium crafted the conceptual framework of Global-DEP, with SESs as its fundamental underpinning. Key elements of the frame-work encompass driving forces, impacts, feedback loops, and scale. The team identified four pivotal themes: (1) dryland SES dynamics and driving forces, (2) dryland SES structure and functions, (3) dryland ecosystem services and human well-being, and (4) ecosystem management and sustainable livelihoods in drylands. The intricate interconnections among these themes were meticulously examined to delineate 12 critical research priorities. Anchored upon this conceptual framework and the identified research imperatives, the Global-DEP science plan was formulated. This plan is poised to expedite actionable interdisciplinary research within dryland SESs, tailored to the regional and cultural nuances of these areas. The final aim is to bolster dryland research endeavors, catering to the requirements of land practitioners and policymakers, while effectively contributing to the attainment of SDGs in drylands.

Abstract:
In the agriculture industry, pest infestation is a significant challenge that is complicated by the nonlinear relationship with environmental factors. Given the effectiveness of machine learning models in simulating such complex nonlinear phenomena, the authors opted to employ them in the modelling of the life cycle of tea pests, which impact several other crops as well. Accordingly, multiple machine learning models were developed to forecast the occurrence of tea pest looper infestations. They utilized data for just two readily available parameters—temperature and rainfall—to investigate whether predictive models of good quality can be created even with limited data, particularly for small tea growers. After analyzing the various models generated, they discovered that neural network models can produce accurate predictions even with a restricted data set. Therefore, they are optimistic that new age technologies such as machine learning can benefit many small farmers in India who lack access to various technologies and, as a result, have limited data.

Abstract:
This chapter describes a two-semester software engineering course that is taught in a computer science program at the University of Texas at El Paso. The course is distinguished from other courses in that it is based on the Affinity Research Group (ARG) philosophy that focuses on the deliberate development of students’ team, professional and technical skills within a cooperative environment. To address the challenge of having to teach professional and team skills as well as software engineering principles, approaches, techniques, and tools in a capstone course, the authors have defined an approach that uses a continuum of instruction, practice, and application with constructive feedback loops. The authors hope that the readers will benefit from the description of the approach and how ARG components are incorporated into the course.

Abstract:
The chapter discusses pedagogical methods and tools that promote individual growth in collaborative school learning processes, emphasizing applied educational research at Europe’s largest real lab, The University School Dresden, with 800 students, 50 teachers, and multidisciplinary scientists. Daily activities involve quick feedback loops, continuous testing, and method/tool refinement for impactful learning. This chapter explores (a) “Learning paths” for guiding individual development, (b) the “Logbook” for planning personalized learning, and (c) the “Lapbook” for project-based activities with peers. These methods align with cultural-historical theory’s view of learning and development. This chapter spotlights tools developed by the research team to enhance self-regulated learning, vital for cultural-historical theory-based learning environments. Initial evidence suggests that (a) tools should align with student development and (b) teachers need continuous professionalization for optimal utility.

Abstract:
Navigating the shift towards blended learning in Higher Education (HE) provides opportunities for enhancing language teaching in the classroom. This paper will present a Technology-Enhanced Learning (TEL) -based project which aims to create a more collaborative and interactive classroom using open access file sharing services which focuses on developing collaborative writing practices and enhancing feedback loops. Using a Synchronous Computer-Mediated Communication (SCMC) approach to co-creating texts, students participated in a series of related in-class group writing tasks where feedback was recorded digitally. Both a survey and focus group were used to assess students’ experience and use of the texts and feedback created. Results revealed a positive response to the use of SCMC for collaborative writing stemming from easier text manipulation and greater discussion of both textual and linguistic features, which is crucial to collaborative writing.

Abstract:
Abstract Midway through the week, the JVC Jazz Festival kicked into life at a sedate homage to Charlie Parker’s romance with strings, when the featured soloist, James Moody, bounded into an exultant “Cherokee,” shaking off the ensemble like a great swan beating the wet from its wings. He soared, dove, and crested. The rhythm section floated him on the song’s hammered harmonies, inspiring him on his tear while the resting chamber players looked slightly glazed with wonder. When he finally looped the last loop into a mocking shave-and-a-haircut finish, the crowd levitated. We talk about bop as though every postwar jazzman who plays changes with a beat enjoys equal access to its mysteries, but in fact few can essay the music’s curvy melodic purity and drive of 50 years ago, when it was mint, daring, and not a little unbelievable. Though Moody was one of the first to augment and even parody the style, he never lost the knack—he just doesn’t go for broke that often. Moody was also one of the first to record with strings, two years after Parker; the subject in 1951 was “Cherokee” and he didn’t do much with the piece that Parker had made his personal anthem. When Moody finally put his mark on the song in the 1960s, he adapted it as a virtuoso shimmered with warmth and seemed to shave 30 years off Brubeck, most of whose best music was achieved in company with saxophonists of Moody’s stature.

Full text
Abstract:
Local, state and federal regulations in the United Sates tend to favor NSCR as the emissions control technology of choice for lower output internal combustion (IC) engines. The technology can achieve extremely low emissions levels for NOx, CO and total hydrocarbons (THC). Theoretically an end user can add it on to any rich burn engine at relatively low cost and the technology scales down to the smallest IC engines. While superficially a "simple and proven" technology, NSCR control is in fact extremely complex, far more complex than the control of lean burn engines. The underlying problems with NSCR control are well documented. Using a systems approach an AETC/HOERBIGER team analyzed each component of the system and identified the core problems and possible solutions. Ultimately the team identified the need for a fully integrated system utilizing linear sensors and actuators. The team then theorized such a system could be controlled by an off the shelf PLC with typical PI control loops. Based on this conclusion HOERBIGER developed an integrated NSCR system utilizing linear sensors and actuators and controlled by an off the shelf PLC. Called the Advanced Richburn Control (ARC), HOERBIGER installed the system on six KVG-410 engines operating in pipeline compression and recorded performance for a year. Those results confirmed the system satisfied the performance requirements and validated the design concept. This report has a related webinar.
