introduction iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. this type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. materials and methods in this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...

Iron deposits in the human brain are characteristic of normal aging but have also been implicated in various neurodegenerative diseases. Among nonhuman primates, strepsirhines are of particular interest because hemosiderosis has been consistently observed in captive aged animals. In particular, the cheirogaleids, because of their small size, rapid maturity, fecundity, and relatively short life ...

The state of Wisconsin has a proud mining history. From the historic lead/zinc mines in the state’s southwest to the iron mines of its north, much has been written of Wisconsin’s mineral wealth and its role in the development of our nation (LaBerge, 1994). So when strong opposition to mining emerged in northern Wisconsin in the 1980’s, I think many of us Michigan geologists looked on with a mix...

In areas where mining encroaches on a previously mined area, the historic mine plans do not always provide accurate information regarding the extent of historic and existing developments. Mining into old workings may result in hazards such as flooding of advancing workings. The development of infrastructure over old workings may also be undesirable, especially in areas that are susceptible to s...

Today, real world time series data sets can take a size up to a trillion observations and even more. Data miners’ task is it to detect new information that is hidden in this massive amount of data. While well known techniques for data mining in cross sections have been developed, time series data mining methods are not as sophisticated and established yet. Large time series bring along problems...

An iron loaded liver from a 40 year old man with occult haemochromatosis was transplanted into a 19 year old woman with acute liver failure secondary to a paracetamol overdose. Increased parenchymal hepatic iron was found in a liver specimen at biopsy undertaken because of mild rejection 30 days after transplantation. After transplantation the patient had two episodes of liver rejection confirm...

We previously demonstrated elevated brain iron levels in myelinated structures and associated cells in a hemochromatosis Hfe (-/-) xTfr2 (mut) mouse model. This was accompanied by altered expression of a group of myelin-related genes, including a suite of genes causatively linked to the rare disease family 'neurodegeneration with brain iron accumulation' (NBIA). Expanded data mining and ontolog...

Mining, as defined by Stocks and Down is the ‘removal of minerals from their natural geological environment and their transport to the point of processing or use1’. As so defined mining has, in one form or another, been providing essential raw materials for tens of thousands of years. Although metal ores were first mined in southern Africa (south of 15°S) approximately 2 000 years ago, minerals...

The collapse of the Fundão dam in Brazil caused one biggest environmental disasters. One challenges was how to manage tailings so that affected areas could be reused. This study aimed verify whether applying different irrigation depths Xaraés grass grown with iron mining would affect shoot and root dry masses. experiment set up a randomized design five (40%, 60%, 80%, 100%, 120% crop evapotrans...
