Terrestrial Oceans And Lunar Maria by G.F. Makarenko

About the Book
Both the Earth and the Moon have been repeatedly involved in episodes of volcanic activity induced by the heating of the interior of the two planets. Before the onset of each epoch of outpourings of lava that filled volcanic seas, arcuate and ring-shaped mountain chains encircled these seas in different regions of the planets.

The Moon is a “simplified model” of the Earth. Reviewing the structures of the Earth and the Moon simultaneously, we shall better understand the origins and compositions of the mountain ranges of the Pacific coast and see why the Atlantic-type oceans are not surrounded by mountains, and what is common in the structure of the volcanic floor of terrestrial oceans and lunar maria.

The book is intended for a wide circle of geologists, geographers, and astronomers and will also be of interest to those who are specializing in the geology of the Earth and the Moon.

About the Author

Galina Makarenko graduated from the Moscow Geological Exploration Institute named after Sergo Ordzhonikidse as an engineer-geologist. She is currently a member of the geological faculty at Moscow State University, where she conducts scientific research in the areas of geotectonics and volcanism. In addition to her research, she teaches general geology and trains both students and post-graduate students.
For many years, Makarenko participated in scientific expeditions in regions of ancient volcanism, with her candidate thesis dedicated to the geology of these areas. Her expeditions to Kamchatka and the Kuril Islands focused on comparing ancient volcanoes with active ones. Her doctoral thesis is centered on the extensive sheets of volcanic rocks found on the Earth’s continents and oceans.

She has published three monographs and numerous articles. Today, the author is actively engaged in collecting new data in the field of comparative planetology.

An Arms Dealer Joins Silicon Valley’s Military Boom

#Arms #Dealer #Joins #Silicon #Valleys #Military #Boom For years, Will Somerindyke sold weapons of war around the world: artillery shells to Ukraine, grenades to U.S.-backed rebels in Syria. With relationships with dozens of top military buyers, he quickly turned his company Regulus Global into one of America’s major international arms dealers. Now, as Silicon Valley investors swarm to back multi-billion dollar…

Planning for cities with linear skylines

Shown below are some of the cities around the globe that have linear skylines. While these can be visually impressive, especially when set as a backdrop against the coastline or mountains, they also can be challenging from a planning and infrastructure perspective, unless they are adapted properly to address this unique urban landform.

Bear in mind, that linear skylines are not just a coastal or narrow valley phenomenon. Las Vegas is perfect example of an inland city with a very linear skyline that resulted in part due to how the city developed as a desert oasis along a single major corridor. Other examples may result from topographic settings like narrow mountain valleys, river valleys, peninsulas, or islands.

The length of linear skylines can tend to dissuade walking, as the distances between sites can be intimidating. Furthermore, if the focus is too concentrated, primary streets that run the length of the skyline, such as the Las Vegas Strip, can become overwhelmed by traffic and people.

That is why it is important to have viable and efficient alternatives — light rail, buses, bicycling routes, trollies, or as Las Vegas has developed, a monorail line. Safe crossings of busy thoroughfares is also needed. As the image are shows, overpasses or tunnels for pedestrians may be necessary. Otherwise, crosswalks must be set up to allow time for safe movement across the avenues.

In some ways, a linear design can be efficient when it comes to utilities, because they can be focused in a narrower area. However, they must constructed of sufficient size and scale to handle the concentrated needs for water, sewer, electricity, gas, etc. Otherwise, the streets and roads may be constantly torn up to increase capacity. Utility managers will also need to address verticality of the service area, to assure water pressure and other services are maintained at their highest levels.

Another important factor to consider is public safety, particularly from fire-fighting and emergency response standpoints. By their very nature, linear skylines tend to be more dense and as a result taller. This is very evident from the photos provided below. How public safety services address the inherently denser and taller structures is critically important for assuring public safety is always a top priority for avoiding potential tragedies.

Another factor to consider for tourist-oriented linear skyline is the variations between on and off-season. Any and all planning efforts will need to take this into account as the extent of impacts can fluctuate greatly over a calendar year.

What is likely to be the most linear (and perhaps vertical) skyline of them all is the controversial 106 mile long, new city of Neom being constructed in Saudi Arabia (see images above and below. How this project will eventually turn out and whether it will achieve the stated goals of livability and sustainability remains to be seen. If it is successful, it may be a defining development for the future. Otherwise, it could be a precautionary tale to avoid excepting very specialized circumstances.

As has been noted throughout this post, linear skylines can have their challenges. How effectively these are addressed will help determine whether or not the infrastructure and services can meet the concentrated demand. At the same time, the opportunities are not quite as apparent. To this retired planner, ambitious individual developments that are overly lengthy or excessively vertical may not achieve their “lofty” goals. Similarly, it remains to be seen how efficient and effective such a narrow, dense and lengthy urban form can be.

Peace!
