The article explains the double objective of democratic ecosocialism. It discusses the objectives of a social economy which are to expand and decommodify universal public services, establish public works programs, introduce a public job guarantee, scale down socially less-necessary forms of production, and reduce excess purchasing power of the rich using wealth taxes and maximum income ratios. Emphasis is given on the need to abolish economic insecurity and for progressive movements to unite.

The article discusses the chemistry and minerals of planet Earth, commenting that the periodic table of the elements is insufficient to categorize the Earth's chemicals in extreme environments and under high pressures, including hydrogen. An overview of the composition of Earth's core, including diamonds, is provided.

Supply demands As presented, the Pressure rides like a very average bike. That's a huge win for the Pressure and, if my own tyre trials proved anything, will begin to unlock this well-conceived frame's true potential, making it a real head turner that's also great fun to ride. The aero-fied Pressure is unashamedly open mould, albeit Cinelli vice-president Fabrizio Aghito says it "isashared project" with the factory that makes it. [Extracted from the article]

The interaction between drill tools and lunar soil played an important role in the field of structure design, performance evaluation, dynamic control, and simulation of lunar autonomous sampler. However, research on the interaction between drill tools and lunar soil is not sufficient to reveal the source of drilling load. Based on the theory of passive earth pressure, it is proposed that the soil mass on the rake face of cutting blade is divided into deposition zone and failure zone according to different soil mass cutting states. Based on the analysis of the contribution from soil mass of deposition zone and failure zone to the total drilling load, a drilling load model for penetrating loosened lunar soil simulant is established. In the end, the drilling load model is verified based on the experimental results of HIT-LS1# lunar soil simulant and HIT-2 drill bit. [ABSTRACT FROM AUTHOR]

The article discusses a study which suggests that earth's water originates from within its mantle where high pressure turns hydrogen and rock into water, causing deep earthquakes. Topics include the use of computer simulation to simulate the reaction of silica or silicon dioxide with liquid hydrogen to form liquid water and silicon hydride, the tendency for water escaping quartz to cause earthquakes, and the possibility for water to be created on other planets in the same way.

The article offers information about the construction of City Rail Link's TBM, operated by the Link Alliance in Auckland.

To date, there is just one possible contender: the Red Planet, a water-free wasteland that boasts no life, an average temperature of -60°C, and less than one per cent of the atmospheric pressure on Earth. The focus on colonising space reminds me of Ancient Greek philosopher Democritus's warning some 2,500 years ago that we should not be "like the dog in Aesop's fable", a hapless creature that loses what he has by chasing something that is not there. For many, there was hope that we might find another habitable planet - somewhere we could move when we had exhausted poor planet Earth. [Extracted from the article]

To get a baseball to curve [on Mars] you would need 130 times as much spin. The rules on Mars may change, and you'll be allowed to have a spin machine on your spacesuit. [Extracted from the article]

The article looks at a report published in "Nature Geoscience" by researcher Arianna Gleason and team on the simulation of conditions in the Earth's inner core by exposing iron foil to extreme pressure and determining its strength, finding that the core metals are relatively weak and nonuniform.

The article looks at a report published in "Nature Geoscience" by geologists Richard Henley and Dion Weatherley on the formation of gold deposits from pressure changes caused by earthquakes. They developed geological models which suggest that earthquakes create cracks in rocks at the speed of sound, causing pressure drops that flash vaporize hydrothermal fluids and promoting the aggregation of soluble minerals such as gold.

My goal is to enhance your movie-going experience, not to be the annoying person who says, "That can't happen." There are movies that get most of their science correct. There's only one flaw in the movie - there's a windstorm on Mars blowing over their rocket ship. [Extracted from the article]

The article highlights the issue about retaining wall products which was featured in an article published in the August 2006 issue of "Landscape Contractor National." Readers claimed that only pinned retaining wall units are specifically designed to properly accommodate earth reinforcement and provide facial stability.

This article discusses how squeezing a common, iron-bearing mineral at the hellish pressures deep within our planet makes the material much stiffer than geophysicists had expected. This response may explain why seismic waves travel particularly fast through some deep zones of rock, say the researchers who performed the experiment. Using vibrations from earthquakes as probes, scientists have detected large volumes of lower-mantle material where seismic waves travel much faster than they do in other mantle areas. Many of those speedups appear at depths of around 2,900 kilometers, says Jung-Fu Lin, a geophysicist at the Lawrence Livermore (Calif.) National Laboratory. Many researchers have proposed that variations in mantle density that result from changes in mineral composition or temperature create those seismic anomalies. One material that the scientists placed in the anvil was magnesiowüstite, a translucent mineral composed of various proportions of iron oxide and magnesium oxide.
