Abstract:
The effect of changes the volume oxygen concentration in the air on the combustion process are showed. Suggested the model for calculating the current concentration of oxygen in air depending from the main meteorological parameters – temperature, absolute pressure and relative humidity. Performed the experimental studies of the daily/seasonal changes of volume oxygen concentration in the air on the basis of direct and indirect measurements. Performed a metrological evaluation of results, confirmed the adequacy of the proposal model. Proposed a formula for calculating the air excess ratio base

The growing e-commerce industry and online shopping is increasing the demand for transportation services world-wide. This expanding industry is beneficial for the economic aspects of society, but the transportation of packages is also causing major environmental impacts along the supply chain. The environmental impact of waste and emissions attributed to the manufacturing and shipment of packages are concluded by many scholars, stressing the importance of sustainable alternatives and innovations. Environmental concerns perceived by customers, governments and other stakeholders are increasingly

Abstract:
In this essay I have estimated what impact the Swedish air passenger tax that was introduced in Sweden on April 1st in 2018 has had on passenger numbers in Sweden. The tax was introduced to lower demand for air travel within the public and thus, decrease the aviation industry´s greenhouse gas emissions as aviation contributes through these emissions to a large extent to climate change and is expected to have an even greater impact in the future as the number of air travels are expected to grow continuously. Besides that the emissions from aviation have this large negative impact on the climate

This thesis examines the use of norms by British and Brazilian actors in the aid/cooperation regime in the 21st century. Using a constructivist approach, this research analyses actors’ agency in asymmetric international and domestic environments, in which different norms, dissimilar identities, and opposing interests coexist. This research argues that, regardless of the discourses and theories surrounding the differentiation between North-South and South-South aid/cooperation, British and Brazilian actors use norms to achieve their own goals at the domestic and international levels.
