In 2005 a Greek and American interdisciplinary team investigated two ship wrecks off the coast of Chios dating to the 4th-century B.C. and the 2nd/lst century. The project pioneered archaeological methods of precision acoustic, digital image, and chemical survey using an autonomous underwater vehicle (AUV) and in-situ sensors, increasing the speed of data acquisition while decreasing costs. The AUV recorded data revealing the physical dimensions, age, cargo, and preservation of the wrecks. The earlier wreck contained more than 350 amphoras, predominantly of Chian type, while the Hellenistic wreck contained about 40 Dressel 1C amphoras. Molecular biological analysis of two amphoras …

Bernadette Marshall

In this edition we will cover the most cost effective choices of reference materials when ordering patent drawings. The type of reference material you supply your draftsperson directly influences the price you pay for patent drawings. Reference material comes in many forms and the better you are at identifying the most useful reference materials, the less you will pay for drawings. It's not complicated and with the following tips I hope you will save money on your next set of patent drawings.

Best Source For Patent Drawing Rules & Regulations, Bernadette Marshall

Bernadette Marshall

It is with great pleasure that I announce something new from NBG-Drafting and Design. This is our first Newsletter - Special Edition; In this edition we will cover our preferred sources for patent drawing rules & regulations. Finding resources for information regarding patent drawing rules can be frustrating. Much of the information refers to out-of-date methods, like hand drawings using ink pens on board. It is hard to imaging creating any type of mechanical/technical drawings today without the use of CADD (software application for computer aided design and drafting). Most skilled patent draftspersons today are practicing in CADD.

The Role Of The Law In The Availability Of Public Transit And Affordable Housing In Atlanta’S West End, Elliott Lipinsky

ELLIOTT LIPINSKY

The Federal Transit Administration (FTA) is a branch of the U.S. Department of Transportation that administers federal funds and provides technical assistance for the support of locally operated public transit systems. MARTA / Atlanta metro area are part of FTA Region IV (the Southeast). FTA would be involved, for instance, in financing the federal grant monies discussed above. But actual regulation of operations (i.e., what MARTA does each day, or what MARTA will plan to do regionally) is more closely regulated by Georgia agencies.

Until recently, the Atlanta metropolitan area had no powerful central agency to coordinate regional transit. The …

Pyrite. History, Chemistry, And Metallurgy, Fathi Habashi

Fathi Habashi

The Book covers the history of pyrite - - how it was a strategic mineral necessary for the production of elemental sulfur needed for making gunpowder for military purposes and for the production of SO2 needed for making sulfuric acid for the chemical industry. Now its presence is a nuisance in tailings ponds. The book also covers the processing of pyrite containing gold, its chemistry and technology, the processing of pyrite cinder for the production of a variety of metals, and its behaviour towards autotrophic microorganisms.
