Influence of roof slope on timber consumption in plane trusses design

The growing world consumption of wood in civil construction is evident, especially in structural roofing systems. Despite being from a renewable source, its rational and intelligent use is of vital importance in the execution of structural designs. Because it is a system that is recognized worldwide in the design of trussing roof structures, there are several empirical assumptions for structural calculation. To reduce timber consumption, some tile manufacturers suggest a 10% (6°) slope between chords. However, after simulations of 11 slopes with angles from 5° to 15°, the timber consumption was inversely proportional to the slope, reaching a 90% difference between extreme angles. The method used to obtain the results was software designed according to the routines prescribed by the new draft standard of ABNT NBR 7190 (2021). Considering a prefabricated truss with 5 cm thickness sections, the design criterion was that of minimum height, increasing by 0.10 cm until all checks were satisfied. Finally, the minimum angle after which no strengthening is required on the bars was 10°.

Rice as a Determinant of Vietnamese Economic Sustainability

This paper aims to examine the rice industry in Vietnam during the period 1997–2017, focusing its production and export. The total area of Vietnam is 33.121 million hectares, out of which 39.25% consists of agricultural land. The agricultural sector adds up to 24% of the gross domestic product (GDP), 20% of the total exports and over 70% of the total employment. Vietnam’s economy is highly dependent on the agricultural sector, specifically rice production, which constitutes 30% of the country’s total agricultural production value. While its production at first aimed to ensure food security in the country, to date, Vietnam is one the world’s largest exporters. While extensive research has explored the rice industry, studies looking at the production through the use of fertilizers, external factors such as the exporting price of other countries and world consumption rates are still lacking. Given the complexity of the topic, data were analyzed through descriptive, econometric and quantitative methods. For production and export analyses, two and four hypotheses were derived and examined, respectively, all based on economic theory. The model consisted of two equations: (i) the paddy production is impacted by rice’s yield and fertilizer use and (ii) in addition to internal factors, the growth of exporting rice in Vietnam depends also on external factors such as Thailand’s rice export price and world consumption rates. Based on the model, a dynamic forecasting method was employed, using the previous forecast values of the dependent variables to compute the future ones. Findings showed that 98% of Vietnam’s rice production is explained through the yield and fertilizer usage and 83% of Vietnam’s rice export is explained by the production, the price in Vietnam and Thailand and the consumption levels around the world. When it comes to forecasting, an 8% growth is predicted with a peak in quantity produced, with 49,461 thousand tons in 2023, yet with difficulties when it comes to exporting. The research predicts a stagnation in exports.

COVID-19 and Catastrophe Capitalism

Since the late twentieth century, capitalist globalization has increasingly adopted the form of interlinked commodity chains controlled by multinational corporations, connecting various production zones, primarily in the Global South, with the apex of world consumption, finance, and accumulation primarily in the Global North. COVID-19 has accentuated as never before the interlinked ecological, epidemiological, and economic vulnerabilities imposed by capitalism.

Emotion Tracking

Previous literature has examined the significance of emotional consumer experiences increasingly pursued by consumers. However, the current knowledge of emotional responses in real-time and real-world consumption settings is still limited. Emotions have previously been measured with observation, self-report, and physiological methods. Digitalization and technological development have, however, advanced these methods as individuals now engage in various self-tracking practices. The chapter introduces emotion tracking as an additional means for measuring emotions. One application, the Emotion Tracker®, was tested by students (n=19) who tracked their emotions (n=617) related to various consumer experiences and reported their user experiences in research diaries. Emotion tracking facilitated real-time and real-world emotion measurement by partly combining the strengths and diminishing the weaknesses of traditional methods. The future of emotion measurement is likely to lie in the combination of subjective and objective self-tracking practices embedded in individuals' everyday lives.

World market of coking coals within the period of 2000–2017 and tendencies of its further development

Data on mining and consumption of coking coals quoted, including China, Australia, Russia, USA and India. It was shown, that China, taking the first place in the world on those indices, keeps a policy of coals mining and consumption cutting. The China authorities set a task to cut coal mining by 500 mt within 3–5 years beginning from 2016, by mines closing and reducing of working days number at coal-mining plants (from 330 down to 276 a year). At Ukraine in 2017 only 5.2 mt of coking coals were mined, relating to the 2000 level it constitutes only 18.8%. A cardinal reduction of coking coals production from 18.9 mt in 2000 down to 2.4 mt in 2017 observed in Germany. The world consumption of coking coals from 2000 through 2017 increased more than two-folds. However, beginning from 2014, a decreasing trend observed. China is the leader in coking coals consumption. The consumption of them increased in 2017 comparing with 2000 more than five-folds. South Korea takes the fifth place by coking coals consumption. The volume of its consumption increased from 2000 through 2017 by factor 1.9. Ukraine, USA and Germany decreased consumption of coking coals within the period under consideration by 44.3, 38.7 and 40.1% correspondently. The coal world export by end of 2017 comparing with 2000 increased by factor 1.7. By results of 2017, Australia exported 62% of the world coking coal trade volume. USA are the second big exporter of coking coals. The export of coals from the USA in 2017 increased comparing with 2000 by 68%.
