The Cost

This chapter examines the role of energy in the economic growth of ancient Greece, with particular emphasis on the impact of the cost of transportation. It first considers the different sources of energy in the Greek city-states, including heat generated by the sun, wood, and charcoal, before discussing the question regarding the cost of energy and the economic conditions for using steam engines during the period. It then explains how wind energy contributed to economic development in the ancient Mediterranean world, and especially in the Greek city-states, by dramatically lowering transport costs and transportation cycles. It also explores how connectivity emerged between Mediterranean countries and concludes with an analysis of overland transportation via roads, the role of ships and ports in maritime transportation, navigational techniques and the construction of artificial ports, and projects aimed at digging canals and building portage routes.

Reaffirming America's role as the global engine of scientific discovery and technological innovation has never been more critical. Challenges like climate change, pandemic disease, and resource scarcity demand innovation. Meanwhile, the nation that leads the world in building a clean energy economy that will enjoy a substantial economic and security advantage. That is why the administration is investing heavily in research, improving education in science and math, promoting developments in energy, and expanding international cooperation. This chapter is aimed to provide the introduction of the significant role of STEM education for national security. The chapter will provide an introduction to integrating the awareness training of national security into higher education with the demonstration of the practice of our education module of DHS CFATS in the chemical engineering course of plant safety and security.

The objective of this paper was to review China’s long-term carbon neutral 2060 policy and to compare with Indonesia’s case in term of energy carriers such as Ammonia and Methanol. Topics regarding China and Indonesia's long-term carbon neutral 2060 policy and strategy are important to be discussed because it will open up issues related to the role of primary energy, chemical-energy nexus and the blue energy economy supported by technology innovation, and political will. The energy-chemical nexus on the background of the Ammonia & Methanol industries are the largest sources of CO2 emissions in China, so it will contribute significantly to emission reductions from the energy transition to carbon neutral energy. From the efforts made by China, it can provide information and considerations to Indonesian policy makers and researchers on their efforts regarding resource management optimization to reconcile the tradeoffs on resources protection and development of socioeconomic as well as to ensure a sustainable system.ABSTRAKTujuan dari makalah ini adalah untuk meninjau kebijakan netral karbon jangka panjang Tiongkok 2060 dan membandingkan dengan kasus Indonesia dalam hal pembawa energi seperti Amoniak dan Metanol. Topik mengenai kebijakan dan strategi jangka panjang karbon netral 2060 Tiongkok dan Indonesia penting untuk dibahas karena akan mengangkat isu terkait peran energi primer, perhubungan energi kimia dan ekonomi energi biru yang didukung oleh inovasi teknologi, dan kemauan politik. Hubungan energi-kimia di latarbelakangi industri Amoniak & Metanol adalah sumber emisi CO2 terbesar di Tiongkok, sehingga akan berkontribusi signifikan terhadap pengurangan emisi dari transisi energi ke energi netral karbon. Dari upaya yang dilakukan oleh Tiongkok, dapat memberikan informasi dan pertimbangan kepada pembuat kebijakan dan peneliti Indonesia tentang upaya mereka mengenai optimalisasi pengelolaan sumber daya untuk mempertemukan timbal balik perlindungan sumber daya dan pengembangan sosial ekonomi serta untuk memastikan sistem yang berkelanjutan.

Amputee Gait

Abstract Background: Energy cost minimization has been widely accepted to regulate gait. Optimization principles have been frequently used to explain how individuals adapt their gait pattern. However, there have been rare attempts to account for the role of variability in this optimization process. Motor redundancy can enable individuals to perform tasks reliably while achieving energy optimization. However, we do not know how the goal-irrelevant and goal-relevant variability is regulated.. In this study, we investigated how unilateral transfemoral amputees regulate step and stride variability based on the task to achieve energy economy. Methods: Nine individuals with unilateral transfemoral amputation walked on a treadmill at speeds of 0.6,0.8,1.0,1.2 and 1.4 m/s using their prescribed passive prostheses. We calculated the step-to-step and stride-to-stride variability and applied goal equivalent manifold (GEM) based control to decompose goal-relevant and goal-irrelevant manifold. To quantify the energy economy, the energy recovery rate (R) was calculated based on potential energy and kinetic energy. Comparisons were made between GEM variabilities and commonly used standard deviation measurements. A linear regression model was used to investigate the trade-off between R and GEM variabilities. Results: Our analysis shows greater variability along the goal-relevant manifold compared to the goal-irrelevant manifold (p<.001). Moreover, our analysis shows lower energy recovery rate for amputee gait compared to nonamputee gait (at least 20% less at faster walking speed). We found a negative relationship between energy recovery rate and goal-irrelevant variability. Compared to the standard deviation measurements, the variability decomposed using GEM reflected the preferred walking speed and the limitation of the passive prosthetic device.Conclusion: Individuals with amputation cleverly leverage task redundancy, regulating step and stride variability to the goal equivalent manifold (GEM). This result suggests that task redundancy enables unilateral amputees to benefit from motor variability in terms of energy economy. The differences observed between prosthetic step and intact step support the development of prosthetic leg capable of enhancing positive work during the double support phase and of powered prosthesis controllers that allow for variability along the task space while minimizing variability that interferes with the task goal. This study provides a different perspective on amputee gait analysis and challenge the field to think differently about the role of variability.

Technology and markets are frequently discussed as the key drivers of the transition to low-carbon economy. Little attention is being given to the role of law. Yet policy and technological innovation directed towards low-carbon energy goals can be both supported and constrained by the legal context. The example of Canada shows how legal systems founded on the rule of law constrain ways in which innovation can occur, based on international law, constitutional law, common law, and legislation. However, new energy policies that are implemented by innovative statutes can support and facilitate technological innovation to address the impacts of climate change.
