Currently, wood waste in the form of a dissected crown on the ground and the root fraction of the tree's biomass in the ground remain in felling areas, becoming potentially dangerous combustible materials in the event of forest fires, as well as obstacles to reforestation activities, and possible foci of infections. Shredding wood waste into wood chips will solve the problem of their disposal by using fuel chips as an additional source of heat energy. In the present work, the influence of design and operational parameters of milling machines with a modernized hydraulic system and equipped with active working bodies on the process of shredding wood waste is established. The annual economic effect from the introduction of the developed complex of wood waste shredding machines and economic indicators from the use of fuel chips are given. This publication is intended for undergraduates and postgraduates engaged in scientific research in the field of forestry mechanization.

This chapter examines the parameters and structure of Salvador's sex tourism industry. Drawing on ethnographic interviews with tour guides and tourism industry workers, it explores the complexities of tourism, race, and sexuality in Salvador. The chapter begins by considering issues of class as they relate to Italian tourists. It then discusses the ways in which sex tourism has been defined and understood in academic scholarship, in the popular media, in government anti–sex tourism campaigns, and by interviewees. It also probes how the Brazilian government defines sex tourism as a manifestation of child sexual exploitation and assesses the perspectives of tour guides and tourism industry workers about how sex tourism operates in Salvador. Finally, it presents case studies that illustrate how Italian men are constructed as the quintessential sex tourists as well as how discourses of class status distinguish who may be considered a sex tourist.

The book offers a new outlook on social, cultural and educational work with young people. It is the perspective of social pedagogy: a theoretical and practical perspective that has been developing in continental Europe over the last 150 years. Social pedagogy poses a way of acting that places young people at the center of socio-educational work, putting their decisions and actions into value. It aims to accompany them in their life process of personal construction within the framework of the community in which they live. The book is organized into three large blocks of chapters. The introduction aims to prepare readers for the social pedagogy approach to work with young people. It briefly outlines its current situation in the world and, relate it to the main professions in which it is embodied in different socio-cultural contexts: social pedagogy, social education, and social work. The first block presents the framework and socio-pedagogical, theoretical, and practical parameters in which work with young people takes place in Europe and Latin America. The second block of chapters deals with youth policies and the training and professionalization of educators and those who work with young people. The last block focuses on some socio-educational practices with young people that include youth justice, social inclusion process, youth participation in digital life or transition to adult life. The book is based on a wide perspective of young people from cultural diversity. All the contributions of this book are based on research and practical experiences.

This book has a very specific target audience: singers and teachers in the vocal field. As a result of his experience as a singing teacher and researcher, he presents readers with an alternative vocal training model aimed at working the high region of male medium voices. To follow this path, we approached issues such as the main common technical difficulties encountered by baritones, aspects of vocal classification, aspirated vocal parameters and vocal physiology. Finally, we discussed possible signs of effectiveness of using a vocalize model that works with falsetto emission to facilitate access to head register notes in male middle voices.

This book develops a new theory of multi-parameter singular integrals associated with Carnot–Carathéodory balls. The book first details the classical theory of Calderón–Zygmund singular integrals and applications to linear partial differential equations. It then outlines the theory of multi-parameter Carnot–Carathéodory geometry, where the main tool is a quantitative version of the classical theorem of Frobenius. The book then gives several examples of multi-parameter singular integrals arising naturally in various problems. The final chapter of the book develops a general theory of singular integrals that generalizes and unifies these examples. This is one of the first general theories of multi-parameter singular integrals that goes beyond the product theory of singular integrals and their analogs. This book will interest graduate students and researchers working in singular integrals and related fields.

Small-handedness continues to be overlooked, discounted, or else treated as a stigmatized disability to the present day. Chapter 1 provides the reader with a historical context for understanding the nature of small-handedness and its impact upon piano playing. Topics include the evolving history of the piano and its relationship to small-handedness, the physiological parameters of hand size, the demographics of small-handedness, and pedagogical and gender biases. The innovation of ergonomically scaled piano keyboards (ESPKs) is briefly addressed. Small-handedness is explored as a risk factor for the development of playing-related injury, and the role of the piano teacher in working with small-handed students is discussed.

This monograph is a continuation of the monograph by V.V. Sadovnikov. Lateral interaction. Moscow 2006. Publishing house "Anta-Eco", 2006. ISBN 5-9730-0017-6. In this work, the foundations of the theory of heterogeneous catalysis and the theory of chemisorption are more easily formulated. The book consists of two parts, closely related to each other. These are the theoretical foundations of heterogeneous catalysis and chemisorption. In the theory of heterogeneous catalysis, an experiment is described in detail, which must be carried out in order to isolate the stages of a catalytic reaction, to find the stoichiometry of each of the stages. This experiment is based on the need to obtain the exact value of the specific surface area of the catalyst, the number of centers at which the reaction proceeds, and the output curves of each of the reaction products. The procedures for obtaining this data are described in detail. Equations are proposed and solved that allow calculating the kinetic parameters of the nonequilibrium stage and the thermodynamic parameters of the equilibrium stage. The description of the quantitative theory of chemisorption is based on the description of the motion of an atom along a crystal face. The axioms on which this mathematics should be based are formulated, the mathematical apparatus of the theory is written and the most detailed instructions on how to use it are presented. The first axiom: an atom, moving along the surface, is present only in places with minima of potential energy. The second axiom: the face of an atom is divided into cells, and the position of the atom on the surface of the face is set by one parameter: the cell number. The third axiom: the atom interacts with the surrounding material bodies only at the points of minimum potential energy. The fourth axiom: the solution of the equations is a map of the arrangement of atoms on the surface. The fifth axiom: quantitative equations are based on the concept of a statistically independent particle. The formation energies of these particles and their concentration are calculated by the developed program. The program based on these axioms allows you to simulate and calculate the interaction energies of atoms on any crystal face. The monograph is intended for students, post-graduate students and researchers studying work and working in petrochemistry and oil refining.

This text is grounded in Barba’s lived experience as a dancer trained in Quito and Brussels. He begins by examining an instance in which a dance is said to look old-fashioned even though it has been recently created. When this judgment occurs across continental boundaries, Barba notes that from a Eurocentric and historicist perspective, working outside the parameters of the so-called centers for contemporary dance can be perceived as traveling back in time. This dismissal of a particular dance, or even of an entire dance tradition, as not really contemporary when identified from within the borders of European modernity is examined and questioned. To navigate through the varied hetero-temporalities enacted in and through different geo-cultural locations, the concepts of historicism (Dipesh Chakrabarty), denial of coevalness (Johannes Fabian), and temporal discrimination (Rolando Vázquez) are applied to this situation of dance and danced reenactment.

Computational design is aimed at supporting automating design processes using computational techniques. However, some classes of design tasks involve criteria that are difficult to handle only with computers. For example, visual design tasks seeking to fulfil aesthetic goals are difficult to handle purely with computers. One promising approach is to leverage human computation; that is, to incorporate human input into the computation process. Crowdsourcing platforms provide a convenient way to integrate such human computation into a working system. In this chapter, we discuss such computational design with crowds in the domain of parameter tweaking tasks in visual design. Parameter tweaking is often performed to maximize the aesthetic quality of designed objects. Computational design powered by crowds can solve this maximization problem by leveraging human computation. We discuss the opportunities and challenges of computational design with crowds with two illustrative examples: (1) estimating the objective function to facilitate the design exploration by a designer and (2) directly searching for the optimal parameter setting that maximizes the objective function.

Any straightforward attempt to capture the interactive relationships between size scales within a complexly layered material such as a bar of steel encounters immediate descriptive obstacles sometimes called the “tyranny-of-scales problem.” These obstacles trace not only to the unmanageable number of descriptive parameters required for such a task but to the fact that the localized models that capture the material’s scale-centered behaviors most effectively are syntactically inconsistent with one another. The innovations of modern multiscalar modeling have surmounted these barriers by developing descriptive architectures that implement clever forms of “divide and conquer” tactics. The tremendous effectiveness of these innovations offers great insight into the workings of practical language in general.

Hard coal mining is characterised by features that pose numerous challenges to its current operations and cause strategic and operational problems in planning its development. The most important of these include the high capital intensity of mining investment projects and the dynamically changing environment in which the sector operates, while the long-term role of the sector is dependent on factors originating at both national and international level. At the same time, the conditions for coal mining are deteriorating, the resources more readily available in active mines are being exhausted, mining depths are increasing, temperature levels in pits are rising, transport routes for staff and materials are getting longer, effective working time is decreasing, natural hazards are increasing, and seams with an increasing content of waste rock are being mined. The mining industry is currently in a very difficult situation, both in technical (mining) and economic terms. It cannot be ignored, however, that the difficult financial situation of Polish mining companies is largely exacerbated by their high operating costs. The cost of obtaining coal and its price are two key elements that determine the level of efficiency of Polish mines. This situation could be improved by streamlining the planning processes. This would involve striving for production planning that is as predictable as possible and, on the other hand, economically efficient. In this respect, it is helpful to plan the production from operating longwalls with full awareness of the complexity of geological and mining conditions and the resulting economic consequences. The constraints on increasing the efficiency of the mining process are due to the technical potential of the mining process, organisational factors and, above all, geological and mining conditions. The main objective of the monograph is to identify relations between geological and mining parameters and the level of longwall mining costs, and their daily output. In view of the above, it was assumed that it was possible to present the relationship between the costs of longwall mining and the daily coal output from a longwall as a function of onerous geological and mining factors. The monograph presents two models of onerous geological and mining conditions, including natural hazards, deposit (seam) parameters, mining (technical) parameters and environmental factors. The models were used to calculate two onerousness indicators, Wue and WUt, which synthetically define the level of impact of onerous geological and mining conditions on the mining process in relation to: —— operating costs at longwall faces – indicator WUe, —— daily longwall mining output – indicator WUt. In the next research step, the analysis of direct relationships of selected geological and mining factors with longwall costs and the mining output level was conducted. For this purpose, two statistical models were built for the following dependent variables: unit operating cost (Model 1) and daily longwall mining output (Model 2). The models served two additional sub-objectives: interpretation of the influence of independent variables on dependent variables and point forecasting. The models were also used for forecasting purposes. Statistical models were built on the basis of historical production results of selected seven Polish mines. On the basis of variability of geological and mining conditions at 120 longwalls, the influence of individual parameters on longwall mining between 2010 and 2019 was determined. The identified relationships made it possible to formulate numerical forecast of unit production cost and daily longwall mining output in relation to the level of expected onerousness. The projection period was assumed to be 2020–2030. On this basis, an opinion was formulated on the forecast of the expected unit production costs and the output of the 259 longwalls planned to be mined at these mines. A procedure scheme was developed using the following methods: 1) Analytic Hierarchy Process (AHP) – mathematical multi-criteria decision-making method, 2) comparative multivariate analysis, 3) regression analysis, 4) Monte Carlo simulation. The utilitarian purpose of the monograph is to provide the research community with the concept of building models that can be used to solve real decision-making problems during longwall planning in hard coal mines. The layout of the monograph, consisting of an introduction, eight main sections and a conclusion, follows the objectives set out above. Section One presents the methodology used to assess the impact of onerous geological and mining conditions on the mining process. Multi-Criteria Decision Analysis (MCDA) is reviewed and basic definitions used in the following part of the paper are introduced. The section includes a description of AHP which was used in the presented analysis. Individual factors resulting from natural hazards, from the geological structure of the deposit (seam), from limitations caused by technical requirements, from the impact of mining on the environment, which affect the mining process, are described exhaustively in Section Two. Sections Three and Four present the construction of two hierarchical models of geological and mining conditions onerousness: the first in the context of extraction costs and the second in relation to daily longwall mining. The procedure for valuing the importance of their components by a group of experts (pairwise comparison of criteria and sub-criteria on the basis of Saaty’s 9-point comparison scale) is presented. The AHP method is very sensitive to even small changes in the value of the comparison matrix. In order to determine the stability of the valuation of both onerousness models, a sensitivity analysis was carried out, which is described in detail in Section Five. Section Six is devoted to the issue of constructing aggregate indices, WUe and WUt, which synthetically measure the impact of onerous geological and mining conditions on the mining process in individual longwalls and allow for a linear ordering of longwalls according to increasing levels of onerousness. Section Seven opens the research part of the work, which analyses the results of the developed models and indicators in individual mines. A detailed analysis is presented of the assessment of the impact of onerous mining conditions on mining costs in selected seams of the analysed mines, and in the case of the impact of onerous mining on daily longwall mining output, the variability of this process in individual fields (lots) of the mines is characterised. Section Eight presents the regression equations for the dependence of the costs and level of extraction on the aggregated onerousness indicators, WUe and WUt. The regression models f(KJC_N) and f(W) developed in this way are used to forecast the unit mining costs and daily output of the designed longwalls in the context of diversified geological and mining conditions. The use of regression models is of great practical importance. It makes it possible to approximate unit costs and daily output for newly designed longwall workings. The use of this knowledge may significantly improve the quality of planning processes and the effectiveness of the mining process.

This book reconstructs the first two decades of the feminist magazine Time and Tide, founded in 1920 by Lady Margaret Rhondda and other women who had been involved in the women’s suffrage movement. Unique in establishing itself as the only female-run general-audience intellectual weekly in what press historians describe as the ‘golden age’ of the weekly review, Time and Tide both challenged persistent prejudices against women’s participation in public life and played an instrumental role in redefining women’s gender roles and identities in the interwar period. Drawing on extensive new archival research the book recovers the contributions to this magazine of both well- and lesser-known British women writers, editors, critics and journalists and explores a cultural dialogue about literature, politics and the arts that took place beyond the parameters of modernist ‘little magazines’. Offering insights into the history and workings of this periodical that no one has dealt with to date, the book makes a major contribution to the history of women’s writing and feminism in Britain between the two world wars. The book is organised chronologically in three parts, tracing Time and Tide’s evolution from its ‘Early Years’ as an overtly feminist magazine (1920-28), to its ‘Expansion’ and rebranding in the late 1920s as a more general-audience weekly review (1928-35), and, finally, to its ‘Reorientation’ in the mid-1930s in response to a world in crisis (1935-39).
