<p>I teach Natural Sciences in a Liceo Artistico, a type of secondary school in Italy. It is designed to give students the skills to progress to any university, but specifically devoted to art related topics.<br>During my career I have been following the national educational standard of the Ministero dell’Istruzione, dell’Università e della Ricerca of my Country.<br>During the years students are involved in meaningful hands-on activities   such as the study of the rocks in the country, preparation of easy chemical reactions and observations through a microscope of vegetal and animal organisms. These last ones are very interesting in a Liceo Artistico where many topics focus on the study of the morphology.<br>The theory confirms what the students learn during the practical activities, furthermore it is important to acquire a correct scientific terminology as well as to be able to express scientific issues.<br>I teach during the year the following main topics:<br>Science of Earth: the Solar System, the two motions of the Earth, structures of the Earth surface (rivers, lakes, glaciers, oceans and seas), the Earth’s Spheres, the movement of lithospheric plates.<br>Biology: the characteristics and functions of living organisms especially the cells and the biodiversity. The Evolution, Mendel’s genetic laws, organism-environment relationship in order to valorize and to maintain the biodiversity. Chemistry: state of matter, classification of matter, the Mendeleev’s Periodic Table, the main chemical reactions, atomics models, chemical bonds, chemical nomenclature.<br>The extra-curricular course proposal of my school (POFT-Piano dell’Offerta Formativa Triennale) includes my project whose title is “Science and creativity”. The achievement is to create a link between scientific subjects and the art ones in order to approach knowledge which appear distant but have really many points to share.<br>Every year some classrooms study different topics such as the Nanoparticles, Biomimetic and this year the Adaptations of the animals.<br>After a scientific conference, plastic models and graphic drawings will be realised by the students, who starting from the scientific reality, can express their creativity.<br>During the years I organize some educational visits for example to the Botanic Garden as well as to the countryside; in this way the students have opportunities to create an e-book with texts and photographs.<br>For instance two years ago my classroom created an e-book with botanical cards and the following year another one with the title “Rocce a Milano” where students took pictures and texts about this topic.<br>Many classrooms and teachers are involved in this project for example Plastic and Drawing teachers, as well as Multimedia teachers. I manage to gather the interested teachers and to realize the projects.<br>With our productions we participate in competitions and we are sometimes selected.</p>

Purpose. The article is devoted to the classification of demonological images in the views of the Tuvans based on the materials gathered during field studies. The mythology associated with evil spirits is subject to transformation. It is a dynamic, ever-changing process. Therefore, the publication of new field materials on this topic will help to clarify the existing ideas about the mythology of the Tuvan ethnos and its evolution. Results. The work gives a general description of evil spirits and their habitats, as well as functional and semantic characteristics, which are reflected in ritual practices and popular knowledge. For the Tuvans, most places inhabited by evil spirits are ambivalent, that is, sacred and forbidden at the same time, as well as transboundary. The results of our studies show that certain places are considered by the Tuvans as sacred due to their ideas about the strength of the earth itself, as well as their beliefs about the existence of spirit masters of the area. Conclusion. In general, the study revealed common and specific features in the anthropology of space, its development, taking into account the management of the economy and the traditional way of life of the Tuvans.

Rational use of natural resources and control over their recovery, as well as over destruction due to natural and technogenic causes, is currently one of the most urgent problems of the humanity. Forests are no exception. Multispectral images from Earth’s satellites are most often used for monitoring changes in forest planting. This is due to the fact that merging images taken in certain spectra makes it possible to recognize vegetation containing chlorophyll quite well. It also allows to detect changes in the level of chlorophyll, which shows the differences between healthy and damaged plants. Large areas of planted forests create the need to process huge amounts of data, which is difficult to do manually. One of the most important stages of image processing is the classification of objects in these images. This paper deals with various classification methods used to solve the problem of classifying images of remote sensing of the Earth. As a result, it was decided to evaluate the accuracy of classification methods on various vegetation indices. In the course of the study, the evaluation algorithm was determined, as well as one of the options for analyzing the results obtained. Conclusions were made about the work of classification methods on different vegetation indices.

The article describes the use of a multi-version approach to improve the accuracy of the classification of images when solving the problem of image analysis for Earth remote sensing. The implementation of this approach makes it possible to reduce the classification error and, consequently, to increase the reliability of processing remote sensing data. A practical study was carried out in a multi-version real-time execution environment, which makes it possible to organize image processing on board of an unmanned vehicle. The results confirm the effectiveness of the proposed approach.

The use of remote sensing techniques allows obtaining information about processes that occur on the surface of the Earth. In the aspects of fire protection and forest protection, it is important to know a burnt area which was created as a result of a fire of the soil cover or a total fire. The knowledge of this area is necessary to assess losses. Remote sensing techniques allow obtaining images in various spectral ranges. Remote sensing satellites offer multi-band data. Mathematical operations that operate on values coming from different spectral ranges allow determining various remote sensing indicators. The manuscript presents the possibility of using the NDVI (Normalized Difference Vegetation Index) to classify the burnt area. The NDVI is relatively easy to obtain because it operates in the spectral ranges from 630 up to 915 nm, and is obtainable with one detector only. Thus, it can be obtained without any major problems using unmanned aerial vehicles, regardless of time and cloudiness, as is the case when acquiring satellite images. The manuscript describes experimental research and presents the results.

This article explores the texts and visual representations of the ‘saints of the bowels’ in order to establish an anthropological classification of aching bellies in early-modern France. A web of symbols is found in the materiality of the viscera. Thus, this article argues that representations of the belly as cave-like mirrors some images of the bowels of the earth. The “Saints of the Entrails”, St Erasmus and St Mammes, and Saint Elmo, all of whom were eviscerated during their martyrdom, represented many popular beliefs of rural communities who conflated images of the soil and images of the belly.

The true test of the classification adopted for European sedimentary formations is to endeavour to apply it in distant parts of the earth. It will then be seen whether the classification in question is real, or whether it is founded on local and accidental peculiarities of the rocks in a particular region.
