Peralkaline Granitic Rocks
The Lower Jurassic (ca. 177 Ma) Bokan Mountain granitic complex, located on southern Prince of Wales Island, southernmost Alaska hosts a high-grade uranium-thorium deposit with past production. The complex is a circular body (~3 km in diameter) which intruded Paleozoic granitoids as well as metasedimentary and metavolcanic rocks of the Alexander Terrane of the North American Cordillera.

Remote Sensing in Wind Erosion Studies
Remote sensing (RS) has revolutionized field data collection processes and provided timely and spatially consistent acquisition of data on the terrestrial landscape properties. The study of wind erosion involves a range of research techniques, such as laboratory and field measurements, modelling, and the use of remote sensing (RS) technologies.

Influence of Smart Cities on Carbon Emission Intensity
The concept of “smart cities” plays a positive role in the overall green and sustainable development of a nation. However, it is still debated whether smart cities can restrain the carbon emission intensity at the micro-level and promote the green transformation of enterprises.

National Association of Manufacturers
The National Association of Manufacturers (NAM) is an advocacy group headquartered in Washington, D.C., United States, with additional offices across the country. It is the nation's largest manufacturing industrial trade association, representing 14,000 small and large manufacturing companies in every industrial sector and in all 50 states. Jay Timmons has led the organization as President and CEO since 2011. A 2018 article by Business Insider described the NAM as "a behemoth in the US capital, receiving unfettered access to the White House and top lawmakers on Capitol Hill." In 2018, House Ways and Means Chairman Kevin Brady commented that passage of the Tax Cuts and Jobs Act would not have happened without leadership from the National Association of Manufacturers. President Donald Trump addressed the NAM board in 2017.

The Development Process of DAUE
Driving analysis of urban expansion (DAUE) is usually implemented to identify the driving factors and their corresponding driving effects/mechanisms for the expansion processes of urban land, aiming to provide scientific guidance for urban planning and management. DAUE is defined to cover all related driving effect/relationship/mechanism research on urban expansion and includes the employed analysis methods within them, i.e., correlation analysis, regression analysis, causal analysis, and so on.

Nanostructured Metal Oxide-Based Acetone Gas Sensors
Acetone is a well-known volatile organic compound that is widely used in different industrial and domestic areas. However, it can have dangerous effects on human life and health. Thus, the realization of sensitive and selective sensors for recognition of acetone is highly important. Among different gas sensors, resistive gas sensors based on nanostructured metal oxide with high surface area, have been widely reported for successful detection of acetone gas, owing to their high sensitivity, fast dynamics, high stability, and low price.

Edible Insects in European Society
Entomophagy has a long and rich history in human culture. In fact, insects have been a part of human diets for thousands of years, with evidence of their consumption found in prehistoric archaeological sites. Throughout history, entomophagy has been a common practice in many cultures, particularly in parts of Africa, Asia, Latin America, and Oceania. In some societies, insects were considered a delicacy and were reserved for special occasions, while, in others, they were a staple food source. The roots of entomophagy vary depending on culture and region, but common reasons include the nutritional benefits of insects, their abundance and accessibility, and the cultural and religious significance of certain species. While the practice of entomophagy has declined in some parts of the world due to the influence of Western culture and industrialization, it continues to be important in many societies. Despite its long history and potential benefits, entomophagy has faced cultural and social stigmas in many parts of the world. However, recent efforts have been made to promote entomophagy as a sustainable and nutritious food source and to challenge cultural biases against insect consumption.

Steamboat Springs (Nevada)
Steamboat Springs is a small volcanic field of rhyolitic lava domes and flows in western Nevada, located south of Reno. There is extensive geothermal activity in the area, including numerous hot springs, steam vents, and fumaroles. The residential portions of this area, located mostly east of Steamboat Creek and south of modern-day SR 341, are now known simply as Steamboat. The state of Nevada has a Steamboat Springs Historical Marker (#198) situated along the eastern shoulder of the busy Carson–Reno Highway (US 395 Alt.), approximately 1.65 miles (2.66 km) south of the Mount Rose Junction (the intersection with SR 341 and SR 431). There were once several mineral spas operating here along Steamboat Creek, with at least one still in business called Steamboat Hot Springs Healing Center & Spa. The water from the springs contains many minerals including: calcium carbonate, magnesium, sodium sulfate, carbon dioxide, lithia, soda and silica.

Lava Tubes' Radar Observation on Moon and Mars
Lava tubes are tunnel–like structures within lava flows and can vary in diameter, length, and shape. Due to the Moon and Mars both having low–gravity environments, the lava tubes on these celestial bodies can have volumes that are 1–3 orders of magnitude larger than those found on Earth.
