Experience and Possibility

This book is concerned with the ontology of the things that we experience, especially in regard to its modal features. Ontology studies the basic categories of beings, including particulars like chairs, properties like being yellow, and relations like being on. But this book focuses specifically on the ontology of the ordinary objects that our sensory experience seems to reveal, for instance blue cars and green trees. It investigates the colors, shapes, and other concrete properties these familiar objects present in experience, their spatial relations, and whatever beyond their concrete properties and relations is required to constitute them as the specific objects that they seem to be. But there is also another aspect of this topic: modality. Modality concerns what is possible and what is necessary, what could be and what must be. The central novelty of the book is an intense focus on the modal aspect of these experienced particulars and properties, and what it can tell us about modality in general. The proper understanding of such properties and relations and such forms of particularity has many implications regarding what is and is not possible. The reality of these sorts of properties, relations, and particularity would involve in surprising ways not merely what would be hence actual but what would be merely possible. And these phenomena support a novel general conception of modality, of the possible and the necessary, according to which the actual and the possible are locally entwined and involve different types of being.

In recent years, Aristotle's treatment of the imagination has become the subject of renewed interest. A pioneering paper by Malcolm Schofield argued that, far from being the rag-bag of widely separate and more or less unrelated concerns that it had previously been generally taken to be, phantasia was, for Aristotle, a ‘loose-knit family concept’ covering all aspects of what Schofield labelled ‘non-paradigmatic sensory experience’. With that conclusion I am more or less in agreement, although only on the condition that ‘sensory’ be given a suitably broad interpretation. My purpose in this paper is to tease out, in a necessarily limited and circumscribed manner, the implications of a proper understanding of Aristotle's developed concept of deliberative imagination, phantasia bouleutikê, for his moral theory and his account of rational action, and to indicate ways in which this is related to his accounts of mental imaging in the rest of the Parva Naturalia.

The article considers the main features of a foreign language lesson in view of the goals and content of the lesson, its complex nature, structure and main types. Considerable attention is paid to the complex nature of work in the classroom, as all elements of language material – phonetic, lexical and grammatical – are interdependent in the implementation of foreign language speech activities. The specifics of goal setting are considered taking into account the features of the lesson, its structure and typology. The purpose of the lesson is a definite reflection of the ultimate goal, a specific part of it. Proper understanding of the purpose of the lesson should be based on a combination of two features of the lesson – language learning and complexity. Each foreign language lesson has a practical, educational and upbringing purpose. The structure of the lesson involves closely interrelated and independent activities of teachers and students, in which the learning process is embodied. The article focuses on the initial stage of a foreign language lesson, which prepares students to implement skills and abilities in various types of speech activities, such as speaking, listening, reading and writing. The beginning of the lesson is one of the constant stages of a foreign language lesson. The initial stage consists of various exercises, mostly oral. It can also be implemented in the form of dialogue between students, in the form of students asking a series of questions on a particular topic addressed to the class. The teacher may also suggest starting the lesson with a story based on familiar and understandable learning material. In addition, individual or frontal control can be performed at the beginning of the lesson. Since a foreign language lesson is a lesson in the development of skills, the stages of communication and consolidation of new knowledge are combined with the performance of various exercises. Lessons of different types, combined for a specific purpose, can form a system of thematic series, within which the objectives of the lessons vary in quantitative and qualitative terms. There are three such systems, namely, the system of lessons aimed at: 1) the development of oral skills and abilities; 2) reading and understanding the text; 3) for the development of both groups of skills. An overview of the typology of foreign language lessons developed and proposed by leading experts in the field of methods of teaching foreign languages is presented in order to emphasize the features of a foreign language lesson.

Numerous concrete and reinforced concrete structures (industrial floors, petrol station or manoeuvring park pavements, elements of sewage system) are subjected to danger of permanent or periodical action of petroleum liquids that often causes the considerable reduction in concrete strength as well as decrease of bond between concrete and steel, which usually results in structure damages. The subject of the paper is estimation of influence of polymer dispersion additive (styrene-acrylic co-polymer and styrene-butadiene latex) onto durability of concrete subjected to action of different types of light liquids. The influence of polymer dispersion additive was confronted with the action of silica fume usually applied for sealing the structure of concrete. In the paper there are presented tests results for different types of light liquids onto such cement-polymer concrete properties as: strength, penetration depth of light liquids into material structure.

AbstractRepresentation and reasoning with qualitative spatial relations is an important problem in artificial intelligence and has wide applications in the fields of geographic information system, computer vision, autonomous robot navigation, natural language understanding, spatial databases and so on. The reasons for this interest in using qualitative spatial relations include cognitive comprehensibility, efficiency and computational facility. This paper summarizes progress in qualitative spatial representation by describing key calculi representing different types of spatial relationships. The paper concludes with a discussion of current research and glimpse of future work.

This paper deals with the possibility of the improvement of pervious concrete properties by incorporation of different types of fibres and studies the effect of short duration vibration of pervious concrete properties in comparison with compaction with wooden lath and hammer. Ten mixtures of pervious concrete were prepared, five of which were compacted with wooden lath and hammer and five by short duration vibration. Density, porosity, permeability and mechanical properties were tested for in hardened pervious concrete specimens. It was concluded that mixtures compacted by short duration vibration had better mechanical properties due to the formation of a viscous layer at the contact surface between the aggregate grain and the cement matrix during the compaction, as well as pore-related properties. The addition of fibres negatively affected porosity and permeability but generally improved mechanical properties of concrete. The positive effect of fibre addition was more emphasised in cases of vibrated mixtures.

The experimental results obtained by studying the influence of different types of fibers on the mechanical properties of fly ash polymer concrete are presented in the paper. The general demand of using wastes found applicability in building material industry because some of them are beneficial in improving concrete properties. The waste additions type fly ash and fibers were incorporated in polymer concrete. The study focused on fibers type glass, polyester, metallic and cellulose. The mechanical properties such as compressive strength, flexural strength and split tensile strength were investigated having in view the type, dosage and length of fibers. The results show that fibers improved mechanical properties in comparison with that of polymer concrete without fibers, the test results being differently influenced by the factors which were considered.

In the last decades, using mineral admixture in concrete became very necessary to improve concrete properties and reduce CO2 emissions associated with the cement production process. Subsequently, more sustainable concrete can be obtained.  Ternary blended cement containing two different types of mineral admixture can achieve ambitious steps in this trend. In this research, the synergic effects of mineral admixtures in ternary blended cement and its effects on concrete fresh properties, strength, durability, and efficiency factors of mineral admixture in ternary blended cement, were reviewed. The main conclusion reached after reviewing many literature pieces is that the concrete with ternary blended cement, depending on types of mineral admixtures used, replacement percentages by weight of cement, and age of concrete, exhibited superior properties than with no mineral admixtures and corresponding binary blended cement concrete.
