We present the most relevant works on jet engine design that utilize thermodynamic cycle of detonative combustion. Detonation engines of various concepts, pulse detonation, rotational and engine with stationary detonation wave, are reviewed. Main trends in detonation engine development are discussed. The most important works that carried out…

Engaging undergraduates in the environmental consequences of fossil fuel usage primes them to consider their own anthropogenic impact, and the benefits and trade-offs of converting to renewable fuel strategies. This laboratory activity explores the potential contaminants (both inorganic and organic) present in the raw fuel and solid waste…

Leaving the plains of North Dakota and entering the hills known as the Turtle Mountains, one becomes surrounded by a deciduous forest, spotted with deer stands, fishing holes, mosquito havens, and secret berry-picking spots. It is here that the Turtle Mountain Band of Chippewa Indians (TMBCI) reservation is found. Located on the TMBCI reservation,…

After World War II there was a push to reinvigorate the economies and industries of Western Europe, and to find methods to avoid the outbreak of more wars in the region. As a result, the European Coal and Steel Community (ECSC) was founded in 1952 (European Coal and Steel Community, 2016) an important step towards the full European Union (EU), led…

Taiwan is a densely populated industrialized country with high-polluting industries. In particular, petrochemical, steel, thermal power, and electronics plants consume a high level of energy. Furthermore, vehicle exhaust emissions are a major contributor to pollution. Collectively, these problems have resulted in high levels of greenhouse gas…

Purpose: This paper aims to explore the potential contribution of integrated traffic and parking management strategies to ensure more rational use of available parking spaces and to reduce fuel consumption and greenhouse gas emissions by commuters traveling to the University of Coimbra (UC) main campus. Design/methodology/approach: An integrated…

Purpose: This paper aims to the environmental awareness raising as a key issue of education for sustainable development. Youth Environmental Volunteers Movement in the area of coastal oil response operations in St. Petersburg is presented in this paper as a successful initiative in the field of environmental awareness through universities and city…

We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as "polymer flooding") enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele-Shaw cell pre-saturated with oil, our laboratory model of…

This paper studies the effect of oil wealth on the provision of education in the early 20th century United States. Using information on the location and discovery of major oil fields, I find that oil wealth increased local revenue and education spending. The quality of white teachers increased, and oil-rich counties were more likely to participate…

A television advertisement and a website present an interesting question: can rail company CSX "really" move a ton of freight 468 miles on a gallon of fuel, or is the claim preposterous? Let us examine the claim, first by understanding what is meant, looking at their data, and then converting units to examine the claim quantitatively.

Oman Vision 2040 strives to continue shifting the country from an oil to a non-oil-based economy by emphasizing the value of diversification in HEIs. This study aims to provide in-depth insights into implementing the knowledge economy strategy in Oman's higher education system and uses a case study methodology, draws on thematic analysis, and…

Mounting evidence finds that early life environmental factors increased the probability of autism spectrum disorder. We estimated prospective associations between early life environmental factors and autism spectrum disorder symptoms in children at the age of 2 years in a population-derived birth cohort, the Barwon Infant Study. Autism spectrum…

This article argues that language students and teachers are changemakers and that, in keeping with progressivist philosophy and the bottom-up social paradigm, they can play a powerful role in creating a better world. As our understanding of the world continues to increase, both students and teachers can use this increased understanding to initiate…

Based on classroom management fostering autonomy support and intrinsic motivation, this study examines effects of reciprocal peer-monitoring of learning behaviours on cognitive and affective outcomes. Within our study, 470 German secondary school students between 13 and 16 years of age participated in a multimodal hands- and minds-on exhibition…

Carbon cycle pool-and-flux reasoning is a critical facet of climate literacy. This article begins with discussion of why this type of reasoning is both challenging and important. Results from two studies are reported. The first describes students' approaches to carbon cycle pool-and-flux reasoning. The second describes and reports results from an…
