`The Very Beautiful Principles Of Natural Philosophy': Michael Faraday, Paper Marbling And The Physics Of Natural Forms, Robert Pepperell
LASER Journal
In 1854, Michael Faraday wrote to thank the author who had sent him a book on the art of paper marbling. In the letter, Faraday referred to `the very beautiful principles of natural philosophy' involved in the process of dropping ink on thickened water. What are the `beautiful principles' that Faraday referred to, and how are they involved in the art of paper marbling? Here I consider some of the physical processes that occur in paper marbling and how the patterns that emerge represent `dissipative structures' that are governed by fundamental principles of nature, in particular the tendency for physical …

Bring On The Heat, Renée Stoute
Bring On The Heat, Renée Stoute
The Journal of International Relations, Peace Studies, and Development
According to the World Economic Forum, in retaliation to European Union sanctions and embargoes, Russia cut EU gas flows by around 80% between May and October 2022 (WEF, 2022). The EU, in turn, has had to not only reduce energy consumption within the public and private sectors but has also scrambled to find energy alternatives to compensate for its energy shortcomings. However, due to the EU’s rejection of Russian oil and gas, there are now opportunities to embrace more sustainable energy alternatives quicker than previously expected. This could lead to a faster transition towards the use of cleaner and more …

Energy And Climate Change Issues Around Csudh, Alex E. Perez, Tara B. Jones, Raju Bista, Parveen K. Chhetri
CSU Journal of Sustainability and Climate Change
Climate change is posing significant challenges to California’s energy sector. Extreme weather events (heat and cold) may pressure existing infrastructure. Many studies have indicated that extreme climate events would impact the energy system by affecting peak electricity demand. However, very few studies have been conducted to understand how disadvantaged communities (DACs) will be impacted. Because of unequal access to energy infrastructure (electricity generation and battery storage), DACs are more vulnerable to power outages due to the rising number of significant weather events caused by climate change. To address the issue of how DACs are disproportionately affected by climate change-related energy …

Geothermal Energy And Its Impacts On The Environment, Aditi Gorthy, Nathan Tran, Laureen Pierre-Louis
Mako: NSU Undergraduate Student Journal
From the multitude of energy sources that we have developed throughout the eons, renewable energy or “clean energy” has been on the rise to combat global warming and climate change which burning nonrenewable sources of energy have contributed to. Before geothermal energy is used as part of the mainstream energy sources some aspects must be analyzed and resolved. Unfortunately, geothermal power plants still release pollutants, such as carbon dioxide and sulfur dioxide, into the environment and cause general environmental disruptions due to drilling and changes in land formations. Recent and future studies have been and should be conducted to find …

Pollution Emissions And Economic Growth In Asia Through The Lens Of The Environmental Kuznets Curve, Brian Jason H. Ponce, Yolanda T. Garcia, Gideon P. Carnaje, Agham C. Cuevas
Journal of Economics, Management and Agricultural Development
The nonlinear relationship of pollution emissions with economic growth alongside energy consumption variables was examined to test the Environmental Kuznets Curve (EKC) hypothesis using a panel sample comprising 34 Asian economies from 2001 to 2013. Panel Autoregressive Distributed Lag models in the forms of Pooled Mean Group and Mean Group models were estimated and tested against one another using the Hausman test. For robustness checks, the same econometric techniques were applied to disaggregated panel groups based on income classifications. The study reveals that, while the EKC hypothesis holds in Asia, the findings were not robust across the disaggregated panel groups. …

Climate Change Curricula In Alberta, Canada: An Intersectional Framing Analysis, Greg Lowan-Trudeau
Northwest Journal of Teacher Education
This article is comprised of a climate change-focused framing analysis of proposed revisions to Alberta, Canada’s K-6 curriculum as an ideologically motivated manifestation of curricular epistemicide. Eisner’s three curricula—the explicit, implicit, and null—and scholarship related to intersectional climate and environmental justice, education, and communication provide the theoretical framework. This inquiry concludes with a critical discussion of and possible alternatives to the revised curriculum with further consideration of the implications for those involved with similar endeavours in other jurisdictions across Canada and around the world.

Mining Energy Consumption As A Function Of Ore Grade Decline: The Case Of Lead And Zinc, Ricardo Magdalena, Alicia Valero, Jose-Luis Palacios, Antonio Valero
Journal of Sustainable Mining
Demand for raw materials is increasing exponentially. To satisfy that demand, more minerals need to be mined from the Earth’s crust. As a result, minerals are being exhausted, and ore grades decline. Lower ore grade mines also mean more energy, which in turn entails fossil fuel emissions and more climate change. This paper estimates the specific energy for the beneficiation process of metals lead and zinc as case studies. The evaluation is performed with specialized software, HSC Chemistry which assesses the specific energy for every stage: comminution, flotation, and refining. Different scenarios have been established to simulate the behavior of …

Multi-Objective Dynamic Programming Algorithm Of Energy-Efficient Scheduling For Tow-Train, Xinyan Zhang, Yuqing Zhou
Journal of System Simulation
Abstract: To balance the performance and energy consumption of the mixed-model assembly lines effectively, a multi-objective energy-saving scheduling method for the tow-train is proposed. The energy-saving objective is introduced into the traditional material handling scheduling model for the tow-train and a multi-objective mixed integer programming model is constructed with two objective functions of minimizing the maximum line-side inventory and the total energy consumption. A forwards multi-objective dynamic programming based on the time window and dominance rules is presented to obtain the Pareto solutions: the definition for new states is given to obtain the Markov property, the time window and dominance …

Forecasting Localized Weather-Based Photovoltaic Energy Production, Kevin Chang, Afreen Siddiqui, Robert Slater
SMU Data Science Review
Photovoltaic (PV) power system performance can vary from nominal specifications when put in application, making it difficult to accurately estimate real power generation at a localized level. As the usage and efficiency of PV systems has increased in recent years, the amount of power contributed to the national power grid from solar irradiation has also increased significantly. However, solar power installations are subject to variances in efficiency and output, driven by differences in system size, local weather, and atmospheric condition changes. With a significant install base in today's world, combined with extensive solar irradiance and meteorological data, the variables exist …

Sodium Borohydride For The Near-Future Energy: A ''Rough Diamond'' For Turkey, Ümi̇t Bi̇lge Demi̇rci̇
Turkish Journal of Chemistry
Boron-based materials are potential solutions in the field of energy. They have been regarded as hydrogen storage materials, liquid fuels of direct liquid-fed fuel cells (DLFCs), electrolytes of battery, and/or energetic substances. A typical example is sodium borohydride (NaBH$_{4}$. In sodium hydroxide-stabilized aqueous solutions, it is seen as an efficient H$_{2}$ generator or a performing fuel of DLFCs. Actually, it plays a wider role; it is also the precursor of several boron-based materials of interest in the field of energy. In other words, it is indirectly considered for other energy applications, i.e. solid electrolytes of all solid-state batteries and hypergolic …

Protecting The Environment: Awareness And Responsibility, Susan E. Mason, James J. Winkelman
Journal of Vincentian Social Action
Protecting the environment is not only the right thing to do, it is the smart thing to do, in terms of both short-term and long term business goals. Green businesses can realize immediate financial benefits from environmental sustainability and energy conservation, and there are branding benefits associated with developing and maintaining a reputation for integrity and social responsibility. All participants first answered demographic questions and then responded to a ten-item questionnaire, which was a modified version of Simpson’s (1998) environmental awareness questionnaire. In conclusion, the study revealed gender, age, and political affiliation difference in environmental awareness.

Public Land & Resources Law Review
Holding that the widespread effects of environmental regulation on the coal industry constituted sufficient importance, the Northern District of West Virginia ordered the Environmental Protection Agency to conduct analysis on employment loss and plant reduction resulting from regulatory effects. In admonishing the EPA’s inaction, the court ruled that the Agency had a non-discretionary duty to evaluate employment and plant reduction. Furthermore, the court held that the EPA’s attempt to put forth general reports in place of required evaluations was an invalid attempt to circumvent its statutory duty.

Electrical Efficiency Of A Solar Cell, Johnnie Cairns
Electrical Efficiency Of A Solar Cell, Johnnie Cairns
Undergraduate Journal of Mathematical Modeling: One + Two
Our goal was to determine the electrical efficiency of a solar cell, specifically a CuInGaSe2 solar cell. Solar cells work by converting energy from the sun in the form of photons to electrical energy in the form of electrons. However, the solar energy converted into electrical energy is limited by a property of solar cells called the quantum efficiency. The quantum efficiency of a solar cell is the fraction of photons hitting the cell that are converted into electrons; quantum efficiency varies as a function of wavelength. Another key component which also varies as a function of wavelength is spectral …
