Crushed Stone Aggregate Resources of Indiana
Indiana Geological Survey Bulletin 42-HMineral aggregate is an aggregation of mineral material, such as
crushed rock, expanded shale, perlite, sand and gravel, shells, or slag.
It is sometimes bound with such material as cement or asphalt or is
sometimes not bound for use as filter stone, flux stone, railroad
ballast, riprap, or road metal. Crushed limestone and dolomite, sand
and gravel, slag, perlite, and expanded shale are the main natural and
fabricated aggregates currently used in Indiana. Some aggregate, such
as sand and gravel, requires little or no processing and can be used
almost as it is mined, but rock must be crushed and sorted into
various desired sizes before it can be used. Many types of rocks can
be used for crushed stone aggregate, but limestone and dolomite are
used exclusively in Indiana (pl. 1). In this report crushed stone is
synonymous with crushed limestone and dolomite.
Each type of aggregate has a distinct advantage with respect to
cost and availability or to a specific use for which one type is more
suited than another. The advantages of crushed limestone and
dolomite are that they can be crushed and sized to meet most specifications,
the materials are clean and angular and bind well with
cementing mixtures, a uniform lithologic composition can be maintained
with little or no selective quarrying in many areas, and they
are available at low cost in most counties in Indiana. Crushed stone
is one of Indiana’s most important mineral commodities, ranking
third in annual value behind coal and cement. During 1969 crushed
stone production in Indiana totaled 25, 516,000 tons and was valued
at $34,418,000.Indiana Department of Natural Resource
Geology for Environmental Planning in Marion County, Indiana
Marion County is the center of a large and rapidly growing urban-industrial complex in the heartland of Indiana. The boundaries of the county and of Indianapolis, the state capital, are the same as a result of the UNIGOV concept. The rapid growth of Indianapolis and its suburbs makes effective land-use planning important for Marion County. This report is designed to provide information, based on the geologic setting of the area, that can be used for effective and environmentally sound development of the county
Neglected diseases of neglected populations: Thinking to reshape the determinants of health in Latin America and the Caribbean
BACKGROUND: People living in poverty throughout the developing world are heavily burdened with neglected communicable diseases and often marginalized by the health sector. These diseases are currently referred to as Neglected Diseases of Neglected Populations. The neglected diseases create social and financial burdens to the individual, the family, the community, and the nation. DISCUSSION: Numerous studies of successful individual interventions to manage communicable disease determinants in various types of communities have been published, but few have applied multiple interventions in an integrated, coordinated manner. We have identified a series of successful interventions and developed three hypothetical scenarios where such interventions could be applied in an integrated, multi-disease, inter-programmatic, and/or inter-sectoral approach for prevention and control of neglected diseases in three different populations: a slum, an indigenous community, and a city with a mix of populations. SUMMARY: The objective of this paper is to identify new opportunities to address neglected diseases, improve community health and promote sustainable development in neglected populations by highlighting examples of key risk and protective factors for neglected diseases which can be managed and implemented through multi-disease-based, integrated, inter-programmatic, and/or inter-sectoral approaches. Based on a literature review, analysis and development of scenarios we visualize how multiple interventions could manage multiple disease problems and propose these as possible strategies to be tested. We seek to stimulate intra- and inter-sectoral dialogue which will help in the construction of new strategies for neglected diseases (particularly for the parasitic diseases) which could benefit the poor and marginalized based on the principle of sustainability and understanding of key determinants of health, and lead to the establishment of pilot projects and activities which can contribute to the achievement of the Millennium Development Goals
