The Perfect AREMA Ballast. AREMA Ballast (4, 4a, 5) is also known as ballast stone, railroad ballast, walking ballast, mainline ballast, shortline ballast, and yard ballast, This material is used primarily for railroads as mainline ballast or cross walk the purpose of AREMA Ballast is to improve drainage. Ordovician Dolomitic Limestone is the perfect source material.

Traditionally, precious stones were the Big Four gemstones — diamonds, emeralds, rubies, and sapphires. Semiprecious stones were everything else. Today, gemologists don't use these terms because they imply that some gems are better or worth more than others. In fact, some socalled semiprecious stones would be worth far more than so ...

The gastropod shell is part of the body of a gastropod or snail, a kind of shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium gastropods appear shellless but may have a remnant within the mantle, or the shell is reduced such that the body cannot be .

 · Polycaprolactone (PCL) was reinforced with natural fibres as they not only permit a substantial reduction of the material costs, but also play a role as reinforcement in mechanical properties. This work was focused on the estimation of mechanical and thermal behaviour based on PCL and Pine Cone particles (PCP) filler at different weight percentages (0, 5, 10, 15, 30 and 45 wt%). Tests results ...

 · The stone technology of the Middle Paleolithic is characterized by a variety of concepts and methods of core reduction. Most of the concepts for flake and blade production follow the principle of predetermination of the blanks, which is achieved by the configuration and preparation of the reduction face and striking platform or by the choice of the direction of .

Cone: The cones resemble with the male cones except in some definite aspects. A single ring of 410 flowers or ovules is present just above each collar (Fig. ). Only a few of the ovules develop into mature seeds (Fig. ). In the young condition, there is hardly any external difference between and male cones.

 · Situated off the northern coast of Honduras, the island of Roatan in the Carribean is a paradise for snorkelling and diving enthusiasts. Teeming with vibrant fishes and magnificent corals, the island is home to sunsoaked white sand beaches, warm tropical waters, and the second largest reef system in the world.

This cut maximizes a gemstone's natural light dispersion, bending light rays toward the center of a stone and the reflecting them out again to produce fire and brilliance. The briolette cut is actually a double rose cut with an elongated coneshaped upper crown and rounded pavilion covered with triangular or rectangular facets.

Cone snails use a radula tooth as a harpoonlike structure for predation. Each of these harpoons is a modified tooth, primarily made of chitin and formed inside the mouth of the snail, in a structure known as the toxoglossan radula. (The radula in most gastropods has rows of many small teeth, and is used for grasping at food and scraping it into the mouth.)
