"Management of rhizoctonia bare patch in the South Australian mallee using a modified direct drilling system, deep-banded urea, and sowing time in relation to the break in the season."

Abstract:
Tillage experiments in the South Australian mallee, over 8 years (1990–97), have demonstrated that cultivation directly below the seed at sowing controls rhizoctonia bare patch as effectively as 1 or 2 cultivations prior to sowing. When combined with a short chemical fallow and the use of press-wheels, this modified direct drilling technique can yield as well as, or better than, conventional farming systems. The combination of modified direct drilling and deep-banded urea increases the control of the disease in the first 2 weeks after the break in the season. In the first 2 weeks after the break, deep banding urea at sowing is more likely to increase yield, than modified direct drilling with urea broadcast at tillering, when both treatments are compared with standard direct drilling. In a reduced tillage system, a cultivation 6–11 days after the break in the season may be more effective in reducing bare patch than a cultivation at other times after the break.

Abstract:
Reduced-tillage practices have allowed leafy spurge to infest cropland. The reduction in leafy spurge infestation and winterhardiness by fall tillage, N application, or herbicide treatment was evaluated. Cultivating leafy spurge twice each fall for 3 yr provided complete control. Cultivation followed by N application at 225 kg ha−1reduced the stand by 85% after 3 yr, whereas N applied alone had little effect. Picloram plus 2,4-D at 0.6 plus 1 kg ha−1reduced the infestation to 65% of the untreated control after 2 yr but then the infestation declined rapidly to 1% after a third application. Leafy spurge cold tolerance decreased as root depth increased. The GR50and LT50, the temperatures required to reduce total dry weight and survival, respectively, by 50% varied by root depth and treatment. For example, the LT50and GR50for untreated leafy spurge averaged −19 and < −20 C for crowns, respectively, compared to the −16 and −18 C for roots from 0 to 15 cm deep and −13 and −12.5 C for roots from 15 to 30 cm deep. The GR50and LT50temperature after 2 yr of treatment was reduced to 0 C by two cultivations in fall or picloram plus 2,4-D. Carbohydrate content was not a good indicator of winterhardiness. Cultivation reduced the leafy spurge root system faster than herbicide treatment especially at the 15- to 30-cm depth.

Abstract:
The influence of agricultural methods and soil and climatic conditions on soybean cultivation in the southern regions of the Amur Region was researched. Schemes of two-factor experiments to study the effectiveness of deepening the arable layer of soil during crop cultivation in 2014–2016 included the following options. Factor A – tillage: autumn – disk plowing or cultivation; spring disk plowing or cultivation; summer – inter-row cultivation with or without para-plowing. The options were combined in different ways, whereby the option of soil tillage with a disc harrow in autumn and spring was taken as control. Factor B: sowing with seeders SZ-5.4 and SP-3.6 L with row spacing (options – 15, 45 and 60 cm) with various tillage systems. In 2017–2018 experiments were carried out according to the following schemes. Factor A – tillage: in autumn tillage depth at 0.12 m with a disc harrower PM-8; in spring, before sowing – at 0.10 m (cultivator Case Tiger Mate 225 – control); autumn – tillage depth at 0.28 m (cultivator Lemken Karat 9/400); spring, before sowing – at 0.10 m (Case Tiger Mate 225). Factor B – seeding units included Amazon DMC 9000 (control); Amazon DMC 1200, Case Pro Disk 500 AFS, John Deer 1890, Lemken Solitair 12, Horsch Pronto 9 DC, Tom’ 12, SP-3.6 L. Deep autumn cultivation, in contrast with disk plowing, ensures a more favorable waterair regime for plants and an increase in soybean yield. Seeding units Case Pro Disk 500 AFS, John Deer 1890, Amazon DMC 9000 and SP-3.6 L used in combination with Lemken Karat 9/400 + Case Tiger Mate 255 machines for deepening the arable layer provided an increase in soybean yield by 25.0–38.3% compared to soil tillage with discs. It is recommended to use wide-span seeding units for soybean cultivation in large and medium-sized farms in fields with subdued relief in accordance with high-intensity technology. It is advisable to use SP-3.6 L seeder with a seed shoe for organic crop production in small-scale agricultural enterprises.

Abstract:
The incidence of rhizoctonia patch was reduced by both intensity and depth of cultivation on a fine white sand near Gibson, W.A. When seed was direct drilled with a triple disc drill, 13.3% of the plot area was covered with patches compared with 16.1% following a tined combine seeder. Direct drilling with a modified tined combine seeder which cultivated 10-cm deep while seeding at 3-cm depth had 6.2% patch and was as effective, in reducing patch area, as the best pre-seeding cultivation treatment of 2 scarifying (6.6%). Deep ripping to a depth of 27 cm with an Agrowplow before scarifying and seeding reduced the incidence of patch to only 2.1%. The area of patch and wheat grain yield were inversely correlated (P< 0.001) and accounted for 32% of the variation. Effects (other than rhizoctonia) on grain yield due to the cultivation treatments are suggested. Cultivation directly below the seed placement with the modified combine increased wheat plant growth and grain yield. Deep ripping further increased above-ground dry matter, and grain yield was 58% greater than the yield from direct drilling with the triple disc drill.

Abstract:
A three-section tillage unit has been developed that allows several operations to be performed in one pass: slotting to a depth twice as deep as cultivation, cultivation, crushing the soil and harrowing. At the same time, the grip width of the chopper and harrow of the first and third sections is equal to the width of three cultivating points, and the second base section is five, the operation of the unit with the proposed arrangement of working units improves the quality of the soil treatment. The design of a universal cultivating point of a new sample is presented, containing a chisel located in the bow and slotting machines in the form of two disks with teeth. Using the proposed universal cultivator point of a new sample provides improved soil cultivation by achieving more stable cultivator progress, increasing the unhindered access of irrigation water to the underlying layers of the root zone of plants, improving the water-air regime of the soil environment, increasing the operational reliability of the slotting machine and reducing the consumption of fuels and lubricants to 15 % A promising direction in the development of combined units with removable working units is the creation of combined working units for both sowing seeds, applying mineral fertilizers and herbicides, with the aim of conducting direct sowing of row crops in both dotted and combined ways. The combination of tillage operations with the placement of several working units on one rack allows you to reduce the number of frames in the unit while reducing the metal consumption of the structure by 10 ... 15%, which leads to an increase in the economic efficiency of the tillage unit.

Abstract:
Under the new situation, it is urgent to strengthen the cultivation of the legal consciousness of young college students, which makes the research on the cultivation and promotion of college students’ legal quality and legal knowledge become very important. This article is aimed at studying the cultivation and promotion of college students’ legal quality and legal knowledge based on deep learning. This article first analyzes the legal quality and legal knowledge level of college students by proposing a questionnaire survey method, interview method, and interdisciplinary research method and establishes an explanatory structure model of the factors affecting the legal quality of college students; secondly, it introduces the basic theories of deep learning and explains its practical application; finally, the training rules of neural network are constructed through experiments, and the stage method of legal quality training based on BP neural network is introduced in detail. Considering that virtual reality technology has recently penetrated into the game industry and other fields, we have reason to believe that it will find ways to enter the legal knowledge training industry. The experimental results of this article show that the cultivation and improvement of college students’ legal quality and legal knowledge based on deep learning can reduce the momentary confusion and impulsiveness of college students. Among them, more than 80% of college students who know a little about the Constitution account for more than 80%, which also shows the importance of cultivating and improving the laws and regulations of college students. The results show that the method is accurate and fast.

Abstract:
With a strong demand for aquatic products, seaweed is a promising application in a wide range of areas, such as food, medicine and energy. Kenya is seen as a country with great potential of expanding its seaweed industry, and by inspiration from the widespread production of algaes at Zanzibar, improvements and adaptations can be made to fit Kenya. One of the places with proper environmental conditions is Shimoni, situated in the south coast of Kenya, and the purpose of this report is to assist on the expansion of seaweed farming in Shimoni, by assessing the possibilities of deep-water cultivations at site, and mediate strengths, weaknesses, opportunities and threats with the technique. In addition, another purpose is also to map out important stakeholders for starting up and expanding the system. The methods SWOT-analysis and stakeholder mapping have been carried out by literature studies and interviews with local scientists. Results have shown that deep-water techniques are less demanding on the environment than cultivations in the intertidal area and may support the local environment if proper conditions are provided for. Seaweed cultivations have large potential as an additional livelihood opportunity in coastal communities, given that adjustments to changes in market prices and environmental conditions can be met. However, deep water methods require larger initial costs than the ones carried out in the intertidal, hence political and technical support may be crucial for launching the system. These processes may be implemented iteratively as business opportunities arise. In conclusion, field research covering non-expected local aspects is further recommended.
Den globala efterfrågan av havsbaserade produkter ökar, och tycks inte mattas av. Algindustrin ses som ett lovande område att kunna bemöta detta behov på grund av sitt breda användningsområde. Mat, medicin och energi är bara några exempel på vad råvaran kan användas till. Kenya ses som ett land med stor potential att expandera sin nuvarande algindustri. Med inspiration av den närliggande storproducenten Zanzibar kan förbättringar och anpassningar göras för att passa in i Kenya. Ett område med bra miljöförutsättningar är Shimoni, beläget i södra Kenya, vilket är området denna rapport fokuserar på. Syftet med rapporten är att utvärdera möjligheterna för att utvidga algodlingar i området genom att studera potentialen hos djupvattenodling. Detta genom att analysera styrkor, svagheter, möjligheter och hot med den specifika tekniken. Syftet är vidare att kartlägga viktiga aktörer som kan ha betydelse vid en uppstart och expandering av odlingarna. Metoderna SWOT-analys och aktörskartläggning har gjorts med litteraturstudier och intervjuer med lokala forskare, som grund. Resultat har visat att djupvattentekniker är mindre påfrestande på miljön än odlingar belägna närmare strandkanten, och kan vara uppbyggande för den lokala miljön om rätt tekniker används. Algodling har en stor potential som en kompletterande sysselsättning i kustområden, om marknadspriset på råvaran höjs och att en viss miljöstandard upprätthålls. Dock så kräver djupvattenodlingar större initiala kostnader än tekniker som placeras vid lägre vattenstånd, vilket gör att politiskt och tekniskt stöd är avgörande för en möjlig uppbyggnad. Detta kan ske stegvis i takt med att nya affärsmöjligheter uppdagas. Slutligen rekommenderas fältstudier för att studera lokala aspekter som kan förekomma, vilka skiljer sig från litteraturen.

Abstract:
La plupart de la diversité biologique est en réalité microbienne. L'arbre phylogénétique des eucaryotes comprend plusieurs grands supergroupes monophylétiques, dont les Opisthokonta. Ce groupe comprend deux branches, les Holozoa, qui inclut les animaux, et les Holomycota, qui regroupe les champignons et leurs parents unicellulaires. Bien que les champignons multicellulaires soient bien connus, nos connaissances sur la diversité des champignons unicellulaires et de leurs parents phylogénétiques restent limitées. Cette fraction unicellulaire comprend plusieurs lignées zoosporiques (par exemple chytrids) au sein des champignons, mais aussi une variété de lignées liées aux champignons classiques : les nucleariids, les rozellids, les aphelids et les microsporidies. Cependant, les relations phylogénétiques de ces lignées entre elles et avec les champignons restent à établir solidement. Les arbres phylogénétiques des gènes d'ARNr 18S environnementaux montrent une grande diversité d'Holomycota unicellulaires dans la plupart des écosystèmes terrestres. Cependant, le signal phylogénétique de ce gène est limité et ne permet pas de résoudre la plupart des relations phylogénétiques profondes. Au cours des dernières années, les techniques à haut débit ont permis de séquencer des centaines de nouveaux génomes et transcriptomes. Cela a permis de réaliser des études phylogénomiques multi-gènes, qui augmentent le signal disponible pour résoudre les relations évolutives. Néanmoins, la plupart de ces génomes correspondent à des espèces fongiques faciles à cultiver, souvent avec un intérêt particulier pour l'homme. Actuellement, les approches de type « omique » à partir des cellules uniques se révèlent comme potentiellement utiles pour étudier les eucaryotes unicellulaires non cultivés, en permettant de reconstruire des analyses phylogénétiques robustes d'une grande diversité environnementale à l'aide de données génomiques et transcriptomiques. Au cours de mon travail de doctorat, j'ai appliqué des approches de « cellule unique » pour obtenir des informations phylogénétiques à partir de lignées Holomycota divergentes, clarifier les relations phylogénétiques entre les champignons et ses proches parents et inférer l'évolution de leurs traits. Plus précisément, j'ai utilisé cette approche pour :1) Générer des données génomiques et transcriptomiques pour les nucleariids et mieux reconstruire les relations internes dans le clade et les caractères présents dans leur ancêtre. Nos résultats confirment que les genres de protistes à thèque Pompholyxophrys et Lithocolla sont en effet des nucleariids et branchent avec Nuclearia, Parvularia et Fonticula. La reconstruction d'une phylogénie robuste de ce groupe nous a permis d’inférer les traits (par exemple pas de flagelle) ancestraux du groupe. 2) Séquencer et analyser de manière comparative le génome de Metchnikovella incurvata, pour confirmer sa position relativement basale dans Microsporidia et déterminer les synapomorphies du clade. L'analyse phylogénomique du metchnikovellid Metchnikovella incurvata a confirmé que des Metchnikovellidae branchent à la base des Core-Microsporidia. Nous avons également confirmé que leur profil métabolique était plus similaire à celui des Core-microsporidia, tous deux ayant réduit de manière similaire leurs gènes / fonctions. 3) Générer des données génomiques pour Amoeboradix gromovi et Sanchytrium tribonematis, qui forment le clade des sanchytrides, une nouvelle lignée de champignons zoosporiques identifiée récemment, et résoudre leur position phylogénétique. L'étude des deux génomes de sanchytrids a clarifié leur placement au sein des Fungi en tant que nouvelle groupe frère des Blastocladiomycota. Des analyses génomiques comparatives montrent que leur métabolisme est réduit par rapport aux lignées apparentées. En particulier, le système flagellaire est fortement réduit par rapport à d'autres Holomycota, avec 4 événements indépendants de perte de flagelle dans le clade
Despite the astonishing diversity of plants, animals and macroscopic fungi, most eukaryotic diversity is actually microbial. The eukaryotic tree comprises several large monophyletic supergroups. One of these groups is the Opisthokonta, which encompasses two branches, Holozoa, including animals, and Holomycota, grouping Fungi and their unicellular relatives. While multicellular fungi are well known, knowledge on the diversity of unicellular Fungi and their phylogenetic relatives is still poor. This unicellular fraction includes several zoosporic lineages (e.g. Chytridiomycota and Blastocladiomycota) within Fungi, but also a variety of lineages related to the classical core Fungi: nucleariids, rozellids, aphelids and Microsporidia. However, the phylogenetic relationships of these lineages among them and with classical Fungi remain to be solidly established. Molecular phylogenetic trees of 18S rRNA genes retrieved from environmental studies have showed a wide diversity of unicellular holomycotans in almost all environments on Earth. However, the phylogenetic signal of this gene is limited and does not allow robustly resolving most deep phylogenetic relationships. During past years, high-throughput techniques have allowed sequencing hundreds of new genomes and transcriptomes. This has made possible to carry out multi-gene phylogenomic studies, which increase the available signal to resolve evolutionary relationships. Nevertheless, most sequenced genomes correspond to easy-to-culture fungal species, often with particular interest for humans (e.g. parasites, plant symbionts, yeast). Recently, single-cell omics has become a potential useful approach to study uncultured unicellular eukaryotes, making it possible to reconstruct robust phylogenetic analyses of a wide environmental diversity using genomic and transcriptomic data. During my PhD work, I have applied single-cell techniques to get phylogenetic information from divergent holomycotan lineages, clarify phylogenetic relationships among fungi and their close relatives and infer trait evolution. More specifically, I have used this approach to: 1) Generate genomic and transcriptomic data for nucleariids and better reconstruct inner relationships in the clade and the characters present in the nucleariid ancestor. Our results confirm that the cover-bearing unicellular genera Pompholyxophrys and Lithocolla are indeed nucleariids and branch together with Nuclearia, Parvularia and Fonticula. The reconstruction of a robust phylogeny for the group allowed us to infer the traits (e.g. no flagellum, glycocalyx, no cover) already present in their ancestor. 2) Sequence and comparatively analyze the genome of Metchnikovella incurvata, to confirm its relatively basal position within Microsporidia, and determine synapomorphies for the clade. Phylogenomic analysis of the metchnikovellid Metchnikovella incurvata confirmed that Metchnikovellidae branch at the base of Core-Microsporidia. We also confirmed their metabolic profile to be more similar to Core-microsporidia, being both similarly reduced in genes/functions. 3) Generate genomic data for Amoeboradix gromovi and Sanchytrium tribonematis, which form the newly described zoosporic fungal clade of sanchytrids, and resolve their phylogenetic position. The study of the two sanchytrid genomes clarified their placement within Fungi as a new clade sister to Blastocladiomycota. Comparative genomics showed that their metabolic composition was reduced in comparison with related lineages. This reduction was especially important in their flagellar toolkit when compared with other Holomycota, confirming 4 independent flagellum loss events in the clade

Abstract:
Cultivating Democracy is the first study of its kind of the world’s largest democracy that shows how the values of republicanism are essential for successful democratic practice. In 1950, after independence, India constituted itself as a sovereign democratic republic. While democracy indicated the character of the vertical representative nature of the relationship between citizens and state, the term republic outlined the horizontal relationship of fraternity between people and an active engagement by citizens. The discussion of Indian politics in this book thereby attends to both its institutional form and its democratic culture and shows how the project of democracy is incomplete unless it is also accompanied by a continual cultivation of active citizenship of republicanism. This book is an anthropological study of the relationship of formal political democracy and the cultivation of active citizenship in one particular rural setting in India, studied from 1998 to 2013. It draws on deep ethnographic engagement with the people and social life in two villages, both during elections and in the time in between them, to show how these two temporalities connect. The analysis shows how an agrarian village society produces the social imaginaries required for democratic and republican values. The ethnographic microscope on a single paddy growing setting allows us to examine how the various social institutions of kinship, economy, and religion are critical sites for the continual civic cultivation of cooperation, vigilance, redistribution, inviolate commitment, and hope—values that are essential for democracy.

Abstract:
This chapter studies how novels circulate among readers between the eighteenth and the early nineteenth centuries. The circulation of texts was plainly central to the broader culture of this period as well as to the social history of its literature. In fact, it performed many important functions in a rapidly changing environment. The mechanisms employed provided ample opportunities for sociability, for the cultivation and display of politeness, and even for genuine philanthropy. They also gave scope for the determined pursuit of self-improvement, for personal education, and, not least, for deep inward satisfaction. In all of this the novel was a crucial factor—helping, as it also benefited from, these vital transformational processes. Above all, its extraordinary cultural and commercial success between 1750 and 1820 confirms much about the scale and sophistication of the methods by which texts were now becoming available to readers.

Full text
Abstract:
Community structure refers to the taxonomic types of microbes and their relative abundance in an environment. This chapter focuses on bacteria with a few words about fungi; protists and viruses are discussed in Chapters 9 and 10. Traditional methods for identifying microbes rely on biochemical testing of phenotype observable in the laboratory. Even for cultivated microbes and larger organisms, the traditional, phenotype approach has been replaced by comparing sequences of specific genes, those for 16S rRNA (archaea and bacteria) or 18S rRNA (microbial eukaryotes). Cultivation-independent approaches based on 16S rRNA gene sequencing have revealed that natural microbial communities have a few abundant types and many rare ones. These organisms differ substantially from those that can be grown in the laboratory using cultivation-dependent approaches. The abundant types of microbes found in soils, freshwater lakes, and oceans all differ. Once thought to be confined to extreme habitats, Archaea are now known to occur everywhere, but are particularly abundant in the deep ocean, where they make up as much as 50% of the total microbial abundance. Dispersal of bacteria and other small microbes is thought to be easy, leading to the Bass Becking hypothesis that “everything is everywhere, but the environment selects.” Among several factors known to affect community structure, salinity and temperature are very important, as is pH especially in soils. In addition to bottom-up factors, both top-down factors, grazing and viral lysis, also shape community structure. According to the Kill the Winner hypothesis, viruses select for fast-growing types, allowing slower growing defensive specialists to survive. Cultivation-independent approaches indicate that fungi are more diverse than previously appreciated, but they are less diverse than bacteria, especially in aquatic habitats. The community structure of fungi is affected by many of the same factors shaping bacterial community structure, but the dispersal of fungi is more limited than that of bacteria. The chapter ends with a discussion about the relationship between community structure and biogeochemical processes. The value of community structure information varies with the process and the degree of metabolic redundancy among the community members for the process.

Full text
Abstract:
Idiocy, once understood as a mark of divine disfavor, is later medicalized under a variety of seemingly scientific classifications, culminating in a eugenic-era fear of the “menace of the feebleminded” and the widespread institutionalization to which it gave rise. In literature and in music, representations of idiocy have generally fallen into a small number of types: the Holy Fool and the Sentimental Idiot; the Wild Child and the Natural Man; the Village Idiot (often played for laughs); and the Eugenic Idiot (simultaneously pitiable and a feared source of violence, possibly sexual in nature). Modernist music represents idiocy in its tendency toward simplification in all domains; its static, nondevelopmental character; its deliberate cultivation of disfluency and inarticulateness; its interest in generic incongruity; its pleasure in low humor; and above all its deep interest in the childlike, the folk, and the primitive (including the racial primitive). As in modernist literature, musical representations of idiocy enable the sorts of compositional innovations that are widely understood as defining musical modernism.

Abstract:
Mystagogical education of the teaching staff in the contemporary civilizatory metamorphose deals with the deep transformations which the civilization passes through, considering the sociological, environmental, political, economic and technological aspects. It deals with human being in this complex relationship analyzing the possible consequences of this process and, in the same way, it points alternative to a right assimilation and the convenience in this new world that rises up result of the metamorphosical process. The main indication remains in comprehending the adoption of mystagogical attitude by the teaching staff and in the formation of the educators. When the subject is the education task intending to overcome its utilitaristic function and preparation for the transactional environment, it suggests that the education points supportive and mystical alternatives in the teaching / learning. It proposes the cultivation and the preparation of the integrator people which teaching condition gets over the technical and the professional perspective, being firstly mystagogos (mystic educators) i.e, people teaching more with their lives and examples than words and contents. The text suggests that the educator’s task is to value the relationship between ourselves, others, the world and the supernatural. The searching points that more than technically prepared teachers, the mystic takes in account the human dimension considering all the potentiallities of the human being to develop himself under professional, intellectual, emotional, spiritual and social point of view.

Abstract:
An orbitally induced increase in summer insolation during the last glacial-interglacial transition enhanced the thermal contrast between land and sea, with land masses heating up compared to the adjacent ocean surface. In North Africa, warmer land surfaces created a low-pressure zone, driving the northward penetration of monsoonal rains originating from the Atlantic Ocean. As a consequence, regions today among the driest of the world were covered by permanent and deep freshwater lakes, some of them being exceptionally large, such as the “Mega” Lake Chad, which covered some 400 000 square kilometers. A dense network of rivers developed.What were the consequences of this climate change on plant distribution and biodiversity? Pollen grains that accumulated over time in lake sediments are useful tools to reconstruct past vegetation assemblages since they are extremely resistant to decay and are produced in great quantities. In addition, their morphological character allows the determination of most plant families and genera.In response to the postglacial humidity increase, tropical taxa that survived as strongly reduced populations during the last glacial period spread widely, shifting latitudes or elevations, expanding population size, or both. In the Saharan desert, pollen of tropical trees (e.g., Celtis) were found in sites located at up to 25°N in southern Libya. In the Equatorial mountains, trees (e.g., Olea and Podocarpus) migrated to higher elevations to form the present-day Afro-montane forests. Patterns of migration were individualistic, with the entire range of some taxa displaced to higher latitudes or shifted from one elevation belt to another. New combinations of climate/environmental conditions allowed the cooccurrences of taxa growing today in separate regions. Such migrational processes and species-overlapping ranges led to a tremendous increase in biodiversity, particularly in the Saharan desert, where more humid-adapted taxa expanded along water courses, lakes, and wetlands, whereas xerophytic populations persisted in drier areas.At the end of the Holocene era, some 2,500 to 4,500 years ago, the majority of sites in tropical Africa recorded a shift to drier conditions, with many lakes and wetlands drying out. The vegetation response to this shift was the overall disruption of the forests and the wide expansion of open landscapes (wooded grasslands, grasslands, and steppes). This environmental crisis created favorable conditions for further plant exploitation and cereal cultivation in the Congo Basin.

Full text
Abstract:
AbstractIn light of the experience of the past three decades—1989 to 2020—the civil society appears as a fragile institution that seems capable of giving rise to the overthrow of dictators as well as to their ready installation; to engender movements of solidarity and inclusion as well as of hatred and violence. To understand what allows these different tendencies to arise from within the civil society requires that we move past a pre-occupation with the structural and socio-economic dimension of the civil society and recover a conception of the civil society as an inherently moral institution. In this regard, the tradition of social analysis pioneered by Alexis de Tocqueville remains singularly instructive. The cultivation of civility, we can learn, is not an automatic by-product of tamed markets, limited government, and vibrant associational life—necessary and important though these are. The dispositions needed to maintain the civil society do not arise with causal necessity even where associations flourish, markets are tamed, and institutions are well-designed. By facing more squarely the deep moral fault-lines of the civil society we can develop a keener sense of the countervailing forces needed to keep the project of the civil society on track.

AbstractThis chapter introduces a study carried out in the context of the transformation of the Lithuanian education system towards inclusive education, with the aim of revealing the educational factors that contribute to students becoming knowledgeable and resourceful expert learners in the universal design for learning (UDL) approach. The UDL framework was chosen as a systematic reasoning instrument for the teacher and the school, aiding in achieving the development of expert learner qualities in every student in the general education context and ensuring the quality of inclusive education. The chapter briefly introduces the theoretical approach of the research, the context of Lithuanian education and the school where the research took place, which is relevant for the interpretation of the results, and other important methodological aspects. The research data show that applying the UDL approach helped the teachers to modify the educational process in order to develop in students the qualities of knowledgeable and resourceful expert learners. The results, presented in a structured manner in the chapter, reveal the process and contributing educational factors to students’ becoming actively perceiving, self-directed, knowledge-creating and co-creating learners and learners constructing their own deep comprehension. The research data reveal the methods used by the teachers to recognise and overcome the barriers in cultivating these qualities in their students. We also identified the emerging changes in teachers’ dispositions when applying the UDL approach and designing lessons aimed at promoting the qualities of knowledgeable and resourceful expert learners.

Abstract:
Abstract The mushroom cultivation is an important smart agriculture in Taiwan. This study uses the deep learning object detection method to inspect the cap flaws or positional imperfection in the automatic production of the mushroom PP-bag packaging. This study uses the UR robotic arm and integrated 3D vision module, and uses the extra positioning axis to achieve the purpose of multi-positioning inspections by robot arm. Projecting the structured LED light sources to the object to be inspected has the advantages of a larger identification ranges and complex objects detection. A duallens CMOS industrial camera is used to capture images, and a 3D point cloud image of a basket of PP-bag packages is created by software calculation, which can obtain detailed information on the appearance of the whole basket of PP-bag packages. Deep learning is performed by the training set with labelling, and the image recognition such as the cap flaws in the PP-bag package or positional shift is performed after the training is completed. In this paper, the image data is divided into four sets of datasets, and the same training parameters are used for individual training. With images of dataset1 and the ambient illumination level of 200 lm to 800 lm, the matching score is up to 0.989. The clamping force and the opening degree are adjusted by the variable jaws. The clamping force of the jaws is maintained at 20 N to prevent the clamping force from damaging the dimensions of the PP-bag package and existing holes inside it, making the product unusable. Using the variable jaws and repeating 30 times of clamping experiments, the hole diameter inside the PP-bag package can still be maintained within around 25 mm, which can meet the needs of the mushroom PP-bag packaging.

Full text
Abstract:
The overall objectives of the project were: (a) To measure and study in situ the effect of irrigation with reclaimed sewage effluents on redox processes and related chemical dynamics in soil profiles of agricultural fields. (b) To study under controlled conditions the kinetics and equilibrium states of selected processes that affect redox conditions in field soils or that are effected by them. Specifically, these include the effects on heavy metals sorption and desorption, and the effect on pesticide degradation. On the basis of the initial results from the field study, increased effort was devoted to clarifying and quantifying the effects of plants and water regime on the soil's redox potential while the study of heavy metals sorption was limited. The use of reclaimed sewage effluents as agricultural irrigation water is increasing at a significant rate. The relatively high levels of suspended and, especially, dissolved organic matter and nitrogen in effluents may affect the redox regime in field soils irrigated with them. In turn, the changes in redox regime may affect, among other parameters, the organic matter and nitrogen dynamics of the root zone and trace organic decomposition processes. Detailed data of the redox potential regime in field plots is lacking, and the detailed mechanisms of its control are obscure and not quantified. The study established the feasibility of long-term, non-disturbing monitoring of redox potential regime in field soils. This may enable to manage soil redox under conditions of continued inputs of wastewater. The importance of controlling the degree of wastewater treatment, particularly of adding ultrafiltration steps and/or tertiary treatment, may be assessed based on these and similar results. Low redox potential was measured in a field site (Site A, KibutzGivat Brenner), that has been irrigated with effluents for 30 years and was used for 15 years for continuous commercial sod production. A permanently reduced horizon (Time weighted averaged pe= 0.33±3.0) was found in this site at the 15 cm depth throughout the measurement period of 10 months. A drastic cultivation intervention, involving prolonged drying and deep plowing operations may be required to reclaim such soils. Site B, characterized by a loamy texture, irrigated with tap water for about 20 years was oxidized (Time weighted average pe=8.1±1.0) throughout the measurement period. Iron in the solid phases of the Givat Brenner soils is chemically-reduced by irrigation. Reduced Fe in these soils causes a change in reactivity toward the pesticide oxamyl, which has been determined to be both cytotoxic and genotoxic to mammalian cells. Reaction of oxamyl with reduced-Fe clay minerals dramatically decreases its cytotoxicity and genotoxicity to mammalian cells. Some other pesticides are affected in the same manner, whereas others are affected in the opposite direction (become more cyto- and genotoxic). Iron-reducing bacteria (FeRB) are abundant in the Givat Brenner soils. FeRB are capable of coupling the oxidation of small molecular weight carbon compounds (fermentation products) to the respiration of iron under anoxic conditions, such as those that occur under flooded soil conditions. FeRB from these soils utilize a variety of Fe forms, including Fe-containing clay minerals, as the sole electron acceptor. Daily cycles of the soil redox potential were discovered and documented in controlled-conditions lysimeter experiments. In the oxic range (pe=12-8) soil redox potential cycling is attributed to the effect of the daily temperature cycle on the equilibrium constant of the oxygenation reaction of H⁺ to form H₂O, and is observed under both effluent and freshwater irrigation. The presence of plants affects considerably the redox potential regime of soils. Redox potential cycling coupled to the irrigation cycles is observed when the soil becomes anoxic and the redox potential is controlled by the Fe(III)/Fe(II) redox couple. This is particularly seen when plants are grown. Re-oxidation of the soil after soil drying at the end of an irrigation cycle is affected to some degree by the water quality. Surprisingly, the results suggest that under certain conditions recovery is less pronounced in the freshwater irrigated soils.
