Congress mandated the establishment of the National Cave and Karst Research Institute in October 1998 to further the science of speleology by facilitating research, to enhance public education, and to promote environmentally sound cave and karst management. Considerable progress has been made during the tenure of the Interim Director (2000-2002) toward making the Institute operational. The scop...

Human activities and natural factors determine the hydrogeochemical characteristics of karst groundwaters their use as drinking water. This study assesses 14 water sources in Apuseni Mountains (NW Romania) potential sources. As shown by Durov Piper diagrams, chemical composition waters is typical it dominated HCO3− Ca2+, having a circumneutral to alkaline pH total dissolved solids ranging betwe...

Jatijajar Village which is included in the Gombong karst area accordance with Minister of Energy and Mineral Resources Decree No. 3043 K / 40 MEM 2014 confirmed by Kebumen Regency Regional Regulation 23 2012 concerning RTRW for 2011 - 2013. Karst a landscape karstification process carbonate rock (CaCO3) deposited after passing through available geological space time. has distinctive hydrologica...

A new challenge which the world will face in near future is the reduction of water resources regarding to global climate changes. Climate change is one of the phenomena which will threats future of the universe. Iran locates in an arid and semi-arid region and has limited water resources. Based on global and Intergovernmental Panel on Climate Change (IPCC) board database and the statistics of s...

The spectrin membrane skeleton is a ubiquitous cytoskeletal structure with several cellular roles, including the maintenance of cell integrity, determination of cell shape and as a contributor to cell polarity. We have isolated mutations in the gene encoding &bgr ;Heavy-spectrin in Drosophila, and have named this essential locus karst. karst mutant individuals have a pleiotropic phenotype chara...

Considering the important roles of carbonate rock fraction in karst rocky desertification areas and their potential for indicating damage to vegetation, improved knowledge is desired to assess the application of spectroscopy and remote sensing to characterizing and quantifying the biophysical constituents of karst landscapes. In this study, we examined the spectra of major surface constituents ...

The worsening of groundwater quality is a huge problem for some regions, especially where a karst aquifer system is the most important water resource because of the deficiency of a well-developed superficial water supply. In this study the chemical quality of a deep aquifer of the Salento peninsula (Southern Italy), where a shallow aquifer and an extensive deep aquifer are exploited as a source...
