the Doce River rise in the southeast-east area (SE-E) of the Iron Quadrangle‚ located in south-central portion (C-S) of the state of Minas Gerais (Figure 1). The Iron Quadrangle is historically known as a rich auri-ferriferous province and is a classic region of the world Precambrian geology (Dorr‚ 1959). Its designation results from the area’s planimetric features‚ with a surface area of around 7‚000 km2‚ comprising the most important iron mines of Minas Gerais (Barbosa‚ 1968) and amongst the most

The discovery of copper does not have an exact date. Copper is said to be a prehistoric element. This element was said to be first discovered around 8000BC. The ancient civilizations started to take the copper out of the ore they found around 4000BC. This is when copper started to be put to good use. Early civilizations discovered that copper is malleable and is sharp. They realized they could make copper into tools and weapons. This was easier than the stone that they were originally using. This

Towards the end of Bernhard Schlink’s best-known novel‚ The Reader‚ the narrator is pondering his future after taking his state exam in law. He has just seen his former lover‚ Hanna Schmitz‚ convicted of war crimes: she had been a concentration camp guard‚ something he hadn’t known when she seduced him as a 15-year-old boy. None of the roles he saw played out in court appeals to him: ‘Prosecution seemed to me as grotesque a simplification as defence‚ and judging was the most grotesque oversimplification

Copper has been used in cookware because of its good thermal conductivity. In Eastern and Western cooking traditions‚ copper cookware sets were popular because they provided the best conductivity‚ and therefore the most even heating and cooking. Copper pots and pans were a staple of the colonial kitchen and have withstood the test of time to remain popular in the professional and home kitchen alike. Copper cookware sets will typically include a saut� pan‚ frying pan and a sauce pan. These are essential

description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric iron must have a design

Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser
