Atmospheric Ionic Deposition in Tropical Sites of Central Sulawesi Determined by Ion Exchange Resin Collectors and Bulk Water Collector
(Water, Air, & Soil Pollution, 2012)In the light of global change, the necessity to monitor atmospheric depositions that have relevant effects on ecosystems is ever increasing particularly for tropical sites. For this study, atmospheric ionic depositions ... -
On the temperature dependence of H-U iso in the riding hydrogen model
(Acta Crystallographica Section A Foundations and Advances, 2014)The temperature dependence of H-Uiso in N-acetyl-l-4-hydroxyproline monohydrate is investigated. Imposing a constant temperature-independent multiplier of 1.2 or 1.5 for the riding hydrogen model is found to be inaccurate, ... -
The optical properties and quantum chemical calculations of thienyl and furyl derivatives of pyrene.
(Physical chemistry chemical physics : PCCP, 2015-09-21)A detailed electrochemical, photophysical and theoretical study is presented for various new thienyl and furyl derivatives of pyrene. Their optical properties are described based on UV-VIS absorption and both steady-state ... -
Influencia de los paleosuelos en los procesos exógenos modernos en la porción noreste de la Cuenca de México
(Boletín de la Sociedad Geológica Mexicana, 2015)Dada la importancia que revisten los suelos en los procesos que ocurren en la zona crítica (zona de interacción entre agua, suelo, aire, organismos), en este trabajo presentamos la distribución temporal y espacial de una ... -
Willy Stoffregen – An early pioneer of advanced ionospheric and auroral research
(History of Geo- and Space Sciences, 2014)We sketch the eventful life of Willy Stoffregen and summarise his engineering and scientific achievements. -
Isotope signatures and hydrochemistry as tools in assessing groundwater occurrence and dynamics in a coastal arid aquifer
(Environmental Earth Sciences, 2016)Groundwater from the La Paz arid coastal aquifer in Baja California, Mexico, is essentially the only source of drinking water for the local population and tourists, as well as irrigation water for agricultural needs. The ... -
Metallic iron for water treatment: Healing a research community
(Journal of New Developments in Chemistry, 2014)Despite two decades of intensive research on using metallic iron (Fe0) for environmental remediation and water treatment, basic concerns about their efficiency still prevail. This communication presents the basic idea of ... -
Water Remediation by Metallic Iron: Much Ado About Nothing - As Profitless as Water in a Sieve?

Degradation of Root Community Traits as Indicator for Transformation of Tropical Lowland Rain Forests into Oil Palm and Rubber Plantations.
(PloS one, 2015)Conversion of tropical forests into intensely managed plantations is a threat to ecosystem functions. On Sumatra, Indonesia, oil palm (Elaeis guineensis) plantations are rapidly expanding, displacing rain forests and ... -
Geochemical/hydrochemical evaluation of the geothermal potential of the Lamongan volcanic field (Eastern Java, Indonesia)
(Geothermal Energy, 2015)Magmatic settings involving active volcanism are potential locations for economic geothermal systems due to the occurrence of high temperature and steam pressures. Indonesia, located along active plate margins, hosts ... -
An optimised whole mount in situ hybridisation protocol for the mollusc Lymnaea stagnalis
(BMC Developmental Biology, 2015)Abstract Background The ability to visualise the expression of individual genes in situ is an invaluable tool for developmental and evolutionary biologists; it allows for the characterisation of gene function, gene regulation ... -
Isotope Dating of the Potash and Rock Salt Deposit at Bamnet Narong, NE-Thailand
(Open Journal of Geology, 2016)Bamnet Narong is located in northeastern Thailand (Chaiyaphum Province). It is the largest salt mine in the country and has been mined for decades. The landscape in this part of Thailand is characterised by a low plateau, ... -

Atmospheric CO2 fertilization effects on biomass yields of 10 crops in northern Germany
(Frontiers in Environmental Science, 2015)The quality and quantity of the influence that atmospheric CO2 has on crop growth is still a matter of debate. This study's aim is to estimate if [CO2] will have an effect on biomass yields at all, to quantify and spatially ... -
Zygomycetes in Vesicular Basanites from Vesteris Seamount, Greenland Basin - A New Type of Cryptoendolithic Fungi.
(PloS one, 2015)Fungi have been recognized as a frequent colonizer of subseafloor basalt but a substantial understanding of their abundance, diversity and ecological role in this environment is still lacking. Here we report fossilized ... -
Aqueous contaminant removal by metallic iron: Is the paradigm shifting?
(Water SA, 2011)Chemical reduction has long dominated the thinking about the mechanism of aqueous contaminant removal in the presence of metallic iron (e.g. Fe0/H2O systems). However, a large body of experimental evidence indicates that ... -
