The extraradical hyphae of arbuscular mycorrhizal fungi (AMF) one plant root system forage for the soil nutrients and induce colonization nearby plants, which leads to formation common networks (CMNs) that interconnect roots. Inoculation with AMF can increase length, surface area volume seedlings in nutrient-limited karstic soils. Mycorrhizal symbioses secrete glomalin help promoting aggregates...
Abstract This paper describes the relation of noble gas temperature (NGT) and mean annual air (MAAT) soil (MAST) through studying water samples meteorological data from six Hungarian regions. Alluvial plains, hilly mountainous regions were studied to investigate effects geomorphological, hydrogeological micro-climatic conditions. Water collected springs wells fed different aquifers. Comparing N...
Karstic cave systems in Slovenia receive substantial amounts of organic input from adjacent forest and freshwater systems. These caves host microbial communities that consist of distinct small colonies differing in colour and shape. Visible to the naked eye, the colonies cover cave walls and are strewn with light-reflecting water droplets. In this study, the diversity of prokaryotes constitutin...
Sulfidic redoxclines are a suitable niche for the growth and activity of different chemo- and photolithotrophic sulphide-oxidizing microbial groups such as the Epsilonproteobacteria and the green sulfur bacteria (GSB). We have investigated the diversity, abundance and contribution to inorganic carbon uptake of Epsilonproteobacteria in a meromictic basin of Lake Banyoles. CARD-FISH counts reveal...
The marine Lake Rogoznica is a small, karstic habitat with potential anthropogenic influence, situated in the eastern-central Adriatic coast. In this naturally eutrophic, hypoxic and periodically anoxic lake, an investigation of the microplankton community was performed during the 19951998 period when the ecology of the lake was greatly influenced by strong stratification and the appearance of ...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
The research focused on assessing groundwater quality in Jawharkel, Ghanikhel, Chak, Mandukhel, Dawrankhel, Noorkhel, Baba Qala, Sanikhel, Muhkumkhel, and Rasheeddan villages, specifically intended to measure physical chemical parameters the mountainous areas of Chak Karstic Sedimentary Basin District, Wardak Province, located Afghanistan’s central part. analyzed included electric conductivity,...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
