Preliminary Study on the use of Sentinel-2A Image for Mapping of Dry Marginal Agricultural Land

The availability of medium resolution satellite imagery (i.e. Sentinel-2A) provides the rapid, low-cost and more accurate mapping. This report presents the use of satellite imagery (Sentinel-2A) for mapping of marginal Agricultural Land in the eastern part of Situbondo Regency. The study area covers three (3) districts, i.e., Arjasa, Jangkar, and Asembagus. This study uses two methods of image classifications (i.e., unsupervised and supervised). Sentinel-2A images for dry seasons of 2018 use for this study. The dry season of this region usually occurs from April to November. Then, 450 ground control point for training areas collected during the fields surveys between June until Octobre 2019. This study also uses multi-band (i.e., 2,3,4,5 and 8A) of the sentinel 2a image. Image treatments use “ Multispect” and SNAP, two open-source image processing software. The procedures include image enhancement, registration, clipping, and classification. The classification consists of pre-processing, processing and post-processing tasks. Then, classification results evaluated by confusion-matrix (overall and kappa accuracy). Furthermore, the thematic maps produce from both unsupervised and supervised classification are then compared to existing thematics maps and statistics data. The unsupervised method use iso-data algorithm and produce five (5) class of land uses, i.e., (1) forestry and plantation; (2) build-up area, (3) irrigated paddy field, (4) non-irrigated rural areas (ladang/tegalan). The unsupervised method did the overall accuracy = 79 % and kappa accuracy = 72%. The supervised methods use maximum-likelihood algorithms and produce six (6) class, i.e., (1) forestry - plantation; (2) urban or build area, (3) irrigated paddy field, (4) non-irrigated rural areas, (5) dry-marginal land and (6) water body. Supervised method provide overall accuracy = 95,8% and kappa accuracy = 93,2%. The result shows the potential use of Sentinel 2A to map dry-marginal agricultural land in the study area.
Tomato juice as a potential replacement for human serum in germ tube test assay

Candida albicans (C. albicans) is the most common opportunistic fungal pathogen often isolated from clinical samples. Traditionally, the differentiation of C. albicans from other Candida species is performed through the germ tube test using human serum. The aim of this study was to assess the use of tomato juice of “Thilina” variety for the differentiation of C. albicans from other non albicans species. This study was carried out using 66 Candida isolates including five Candida standards. Candidal suspension (100 μl) equals to 0.5 McFarland was mixed with 1 ml of fresh human serum and 1 ml of tomato juice, separately. Test tubes were incubated at 37 oC and the observations were made at 15 minute intervals for two hours. The tomato juice exhibited 97% sensitivity, 100% specificity, 97% positive predictive value, 100% negative predictive value and higher positive correlation (R2 > 0.6) in producing results. There was no statistically significant difference (P = 0.05) in the meantime of initial germ tube production when tomato juice was compared with the routine serum medium. For the first time the study strongly suggests that human serum can be replaced by juice of “Thilina” variety of tomato for the differentiation of C. albicans from non albicans species.
A family of transcription factors that limit lifespan: ETS factors have conserved roles in longevity

Increasing average population age, and the accompanying burden of ill health, is one of the public health crises of our time. Understanding the basic biology of the ageing process may help ameliorate the pathologies that characterise old age. Ageing can be modulated, often through changes in gene expression where regulation of transcription plays a pivotal role. Activities of Forkhead transcription factors (TFs) are known to extend lifespan, but detailed knowledge of the broader transcriptional networks that promote longevity is lacking. This study focuses on the E twenty-six (ETS) family of TFs. This family of TFs is large, conserved across metazoa, and known to play roles in development and cancer, but the role of its members in ageing has not been studied extensively. In Drosophila, an ETS transcriptional repressor, Aop, and an ETS transcriptional activator, Pnt, are known to genetically interact with Foxo and activating Aop is sufficient to extend lifespan. Here, it is shown that Aop and Foxo effect a related gene-expression programme. Additionally, Aop can modulate Foxo’s transcriptional output to moderate or synergise with Foxo activity depending on promoter context, both in vitro and in vivo. In vivo genome-wide mRNA expression analysis in response to Aop, Pnt or Foxo indicated, and further experiments confirmed, that combinatorial activities of the three TFs dictate metabolic status, and that direct reduction of Pnt activity is sufficient to promote longevity. The role of ETS factors in longevity was not limited to Pnt and Aop. Knockdown of Ets21c or Eip74EF in distinct cell types also extended lifespan, revealing that lifespan is limited by transcription from the ETS binding site in multiple cellular contexts. Reducing the activity of the C. elegans ETS TF Lin-1 also extended lifespan, a finding that corroborates established evidence of roles of this TF family in ageing. Altogether, these results reveal the ETS family of TFs as pervasive and evolutionarily conserved brokers of longevity.
Protected-Denomination-of-Origin Cocoa Bean: Chain governance and Sustainability Performance

The Protected Denominations of Origin in agricultural goods through recognized chains, have a fundamental economic role. In Ecuador, the pdo cocoa bean certification becomes a protagonist since it presents an opportunity to boost the social performance of smallholders. A substantial amount of research focused only on examining the crop performance of pdo products. However, there is a shift in the agricultural chain perspective towards more sustainable models. In this respect, social, economic, and institutional aspects are consequential and tribute to the agricultural sector development. Also, the current rise of market opportunities at the local and international levels is a driver to support them. This study aimed to analyze socio-economic and governance components to understand the pdo Cocoa Arriba (Theobroma cacao) chain sustainability performance and bring forward potential strategies. Principal Components Analysis was introduced to contribute with relevant insights. The framework applied accounts with a revision of primary and support activities. The investigation clustered pre-production, production, and post-production tiers. Also, it executed the food chain mapping and identification of chain actors. Results stated several viable long-term strategies. Examples of those strategies are the enhancement of national regulation to assist chain actors and the stimulus of young producers and associations empowerment. The main research contribution is the application of governance mechanisms to assess the chain performance comprehensively. Based on the results, our recommendation is to incorporate new indicators to analyze the environmental and institutional components profoundly.
Flexible inkjet printed sensors for behind-the-ear SSVEP EEG monitoring

Steady State Visual Evoked Potentials (SSVEPs) are a characteristic brain pattern that emerge in the Electroencephalogram (EEG) when a light source is flashed at a user. The EEG signal oscillates at the stimulation frequency, and this process forms the basis of many Brain-Computer Interfaces. This paper presents flexible inkjet printed sensors for the recording of SSVEPs. The flexible sensors obtain a capacitive connection to the body with an adhesive layer all the way under the electrode for maintaining a good body contact. The result is that SSVEPs can be recorded from behind a single ear without the need to use a conductive gel to lower the body connection impedance. The behind-the-ear location makes the electrodes very suitable for use in hearables and similar socially discrete wearable sensors for providing long term out-of-the-lab Brain-Computer Interfaces.
Assessing the Relationship Between the Blood-Air Partition Coefficient and Fractional Uptake of Inspired Halothane, Acetone, and Ethanol Vapors in the Airways of the C57BL/6J Mouse

The following series of studies investigates the elimination and uptake trends of halothane, acetone, and ethanol vapors in the airways of C57BL/6J mice. These vapors were chosen because they span a wide range of solubilities, as indicated by their blood-air partition coefficients, and are not associated with any significant airway metabolism or reactivity with tissue substrates in vivo. Mice were exposed to a homogeneous vapor mixture containing a 1:1:1 ratio of halothane, acetone, and ethanol at relative concentrations of approximately 10 ppm. Exposure studies were performed with mice in two states, conscious and deceased, in order to provide control against adsorption to superficial anatomical features. Elimination rates were measured by recording airborne vapor concentrations at discrete intervals via gas chromatography. Decay constants were obtained through log-linear regression analysis, and were used to calculate clearances and fractional uptake ratios. The average clearance per mouse for halothane, acetone, and ethanol vapors was 20.9 ± 1.70 mL/min, 51.9 ± 1.88 mL/min, and 52.2 ± 1.54 mL/min (normalized mean ± standard deviation), respectively. Fractional uptake values for each vapor were, in the same order, 0.238 ± 0.053, 0.589 ± 0.123, and 0.593 ± 0.123. A nonlinear relationship between the blood-air partition coefficient and airway extraction was
Traditional Medicinal Plants Used for the Treatment of Gastrointestinal Diseases in Chiapas, México

: Traditional medicine has strong roots in the Mexican population, particularly in areas where the diversity of species of plants and ethnic groups is higher. Such is the case of the southern Mexican state of Chiapas, home to one of the largest indigenous populations in the country. The primary objective of this work is to summarize information regarding traditional applications of medicinal plants used for the treatment of gastrointestinal disorders in Chiapas, México. The study is based on a review of the literature published in scientific journals, books and reports from national, regional and international organizations, theses, conference papers and other grey literature. A total of 52 medicinal plants, grouped in 23 taxonomic families, in addition to their ethno medical information, popular uses, the part or parts employed and their biological activity are described. This study aims at emphasizing the profound importance of investigating those species of plants that have not been the subject of any pharmacological study, in spite of existing reports on their traditional use.

Composés à base de silicium ultra-divisé pour électrodes négatives d'accumulateur lithium ion

Actuellement, le silicium apparait comme le materiau d'electrode negative le plus prometteur grâce a sa capacite specifique theorique de 3580Ah/g mais presente une expansion volumique jusqu'a +280% lors de l'insertion du lithium qui provoque la pulverisation des particules. La premiere partie de la these consiste a etudier les contraintes engendrees par les fluctuations repetees durant le cyclage a l'aide de la technique d'emission acoustique. Les phenomenes de passivation et d'insertion du lithium sont etudies pour des tailles de particules differentes. Une autre partie s'est focalisee sur la synthese de composite C/Si pour attenuer ces phenomenes de degradation. Plusieurs voies sont envisagees : le silicium sur carbone, le silicium dans une matrice carbonee, ou greffage de silicium et de carbone. La premiere technique est un depot en phase vapeur avec tambour a partir de silane. La synthese de matrice carbonee incorporant des poudres nanometriques de silicium passe par une etape d'atomisation. La methode de greffage consiste a lier le carbone et le silicium grâce a un pont chimique. Le comportement electrochimique des composites est analyse pour chaque technique de synthese.
Dramalek med fortelling. Om å skape rom for kulturell forståelse og identitet hos barn

The article examines how narrative can make room for cultural identity in the kindergarten. On thebasis of Ricoeur’s theory of narrative significance for the formation of cultural identity and understanding, key elements for an art pedagogy focused on the children’s cultural expressions are derived. Thearticle visualizes how interaction is crucial on all levels; between different perspectives in the narrative;between narratives in different cultures; and between the children’s own narratives and the one told. Italso singles out specific techniques (eg. defining space and hotseat) that facilitate dialogue from differentperspectives, and thus the children’s co-creation of significance and identity.
Effects of co-cropping on bioaccumulation of trace elements in Thlaspi caerulescens and Salix dasyclados.

Most phytoremediation technologies are based on the use of selected plant species cropped as in monoculture. Separated (monoculture) and combined (simultaneous) cropping of hyperaccumulator Thlaspi caerulescens and accumulator tree Salix dasyclados were tested in our experiment. We used moderately and highly contaminated soil. Extremely contaminated soil caused progressive mortality of willows planted separately. Combined cropping with T. caerulescens enabled willows to survive. Generally, we determined decreased bioaccumulation of As, Cd, and Pb in both tested species and Zn in willow plants. Combined cropping enhanced bioaccumulation of Zn in T. caerulescens shoots. The remediation efficiency of the individual species in the co-cropping system did not differ from those obtained in separate cropping mode. For As and Pb the negligible effectiveness of phytoextraction was confirmed for both separate and combined cropping of the tested plant species.
Blockchain-Based Data-Preserving AI Learning Environment Model for AI Cybersecurity Systems in IoT Service Environments

Artificial intelligence (AI) has a limitation in that it is only in the passive cognition area, so its operating process is not transparent; therefore, the technology relies on learning data. Since raw data for AI learning are processed and inspected manually to assure high quality for sophisticated AI learning, human errors are inevitable, and damaged and incomplete data and differences from the original data may lead to unexpected outputs of AI learning for which processed data are used. In this context, this research examines cases where AI learning data were inaccurate, in terms of cybersecurity, and the need for learning data management before machine learning through analysis of cybersecurity attack techniques, and we propose the direction of establishing a data-preserving AI system, which is a blockchain-based learning data environment model to verify the integrity of learning data. The data-preserving AI learning environment model is expected to prevent cyberattacks and data deterioration that may occur when data are provided and utilized in an open network for the processing and collection of raw data.
A new record of Wolbachia in the elephant ticks from Thailand

: A new record of Wolbachia has been reported and characterized for the ﬁrst time in ticks associated with the Asiatic elephant, Elephas maximas , in Prachuap Khiri Khan Province, Thailand. It was found in one pool of the Rhipicephalus microplus larvae based on PCR ampliﬁcation and DNA sequencing of the partial 16S rRNA gene. The phylogenetic relationships among the Wolbachia identiﬁed in this study and other 21 Wolbachia from supergroups A–I were inferred through comparison of partial sequences of the 16S rRNA gene. Interestingly, this Wolbachia strain was closely related to those from supergroup A found in Ixodes ricinus ticks. Our ﬁndings warrant further investigation as this Wolbachia has a potential use for the biological control of ticks in this region. We also present a phylogenetic analysis of partial 16S rRNA sequences from this Wolbachia
Linking of Traditional Food and Tourism. The Best Pork of Wielkopolska—Culinary Tourist Trail: A Case Study

Agriculture, food and tourism is combined into offering tourist products in rural areas. The development of local activities combining traditional food and tourism becomes an investment for the future with both the concept of sustainable gastronomy and agriculture sustainability, and helps in the development of local entrepreneurship in rural areas. The European Union has introduced provisions for the protection of traditional and regional food that can be used to create a variety of tourist products. Currently, tourists are looking for unique local products. More and more people travel because of culinary motifs, and local products, dishes and local processors can become an attraction in these places. This paper presents the idea of ‘The Best Pork of Wielkopolska’ culinary trail, which is based on a local product from Wielkopolska, in Poland—the native breed of pig—the Zlotnicka White pig. The rapid development of culinary tourism means that tourists are looking for offers in this area. There are many cooking-related products available in the tourism market, one of which is the culinary trail. Food becomes one of the advantages of places where tourism related to the culture of the region develops. Based on cultural heritage, a variety of tourist products can be created, e.g., culinary trails combining agriculture and food produced in this area with tourism.
Quantifying forest cover at Mount Kenya: Use of Sentinel-2 for a discrimination of tropical tree composites

The aim of the present study is to test ESA’s Sentinel-2 (S2) satellites (S2A and S2B) for an efficient quantification of land cover (LC) and forest compositions in a tropical environment southwest of Mount Kenya. Furthermore, outcome of the research is used to validate ESA’s S2 prototype LC 20 m map of Africa that was produced in 2016. A decision tree that is based on significant altitudinal ranges was used to discriminate four natural tree compositions that occur within the investigation area. In addition, the classification process was supported by Google Earth images, and land use (LU) data that were provided by the local Kenyan Forest Service (KFS). Final classification products include four LC classes and five subclasses of forest (four natural forest subclasses plus one non-natural forest class). Results of the Jeffries-Matusita (JM) distance test show significant differences in spectral separability between all classes. Furthermore, the study identifies spectral signatures and significant wavelengths for a classification of all LC classes and forest subclasses where wavelengths of SWIR and the red-edge domain show highest importance for the discrimination of tree compositions. Finally, considerable differences can be seen between the utilized multi-temporal classification set (total of 39 bands from three acquisition dates) and ESA’s S2 prototype LC 20 m map of Africa 2016. A visual comparison of ESA’s prototype map within the investigation area indicates an overrepresentation of tree cover areas (as confirmed in previous studies) and also an underrepresentation of water. Key words: Tropical tree composites, Mt. Kenya, Sentinel-2, ESA S2 LC 20 m map of Africa.
Ressentis et stratégies des médecins généralistes vis-à-vis de l’obligation de réaliser un électrocardiogramme lors des visites de non contre-indication à la pratique sportive : étude qualitative par entretiens semi-dirigés auprès de 12 médecins généralistes

Introduction : l’electrocardiogramme (ECG) a ete rendu obligatoire pour les licencies de de rugby durant la saison 2017-2018. Cette obligation s’appuie sur la Societe Francaise de Cardiologie qui recommande la realisation d’un ECG tous les 3 ans entre 12 et 20 ans puis tous les 5 ans jusqu’a 35 ans. L’objectif etant le depistage des cardiopathies congenitales et la prevention de la mort subite. Objectif : connaitre les ressentis et les strategies des medecins generalistes vis-a-vis de l’obligation de realiser un ECG lors des VNCI. Materiel et methodes : etude qualitative par entretiens semi-diriges aupres de 12 medecins generalistes (MG). Resultats : 12 entretiens semi-diriges ont ete realises. La VNCI est une consultation primordiale pour la plupart des MG. Elle permet de faire de la prevention aupres d’une population qui consulte peu car en bonne sante. Lors de la saison 2017-2018, certains MG ont ete confrontes a l’obligation de realiser un ECG pour la signature de la licence. Certains l’ont realise sans difficulte, d’autres ont choisi de contourner cette obligation pour ne pas penaliser leurs patients. Devant ce caractere obligatoire, certains medecins decrivent un malaise, un sentiment d’incompetence face a l’interpretation de l’ECG du sportif, ou encore une forme d’illegitimite devant le manque de justification bibliographique. Dans l’hypothese ou cet examen obligatoire se generaliserait, les MG envisagent diverses strategies : lutter contre cette obligation qu’ils jugent injustifiee ; se former a la lecture des ECG ; collaborer avec d’autres acteurs medicaux et paramedicaux et utiliser la teleexpertise comme strategie d’interpretation a distance. Les federations sportives et la CPAM pourraient egalement avoir un role a jouer en cas de generalisation de l’obligation. Conclusion : l’obligation de realiser un ECG lors des VNCI entraine de multiples difficultes et questionnements chez les MG. Cependant, si les benefices de ce depistage sont averes, ils sont prets a s’adapter et proposer differentes strategies pour le realiser.
