Development and application of an electrical conductivity transfer function, using diatoms from lakes in the Urals, Russia

Diatom Taxonomic Composition as a Biological Indicator of the Ecological Health and Status of a River Basin under Agricultural Influence

“…In genus level, stations in the Group-3 are located in the negative direction of axis 1, which are included in the arrows of EC, COD and TP. EC is an index of the total ionic concentration in rivers and had an effect on the diatoms community assembly, with individual diatoms showing affinity for particular ions under effect of herbicide contaminate rivers [36].The effects of EC on the distribution of diatom taxonomic composition have been reported by recent studies in rivers [37], lakes [38] and wetlands [39] during warm seasons. Pestryakova et al recorded that diatom composition changed significantly along conductivity gradients in cold lake [40].…”

Dataset of diatom abundances and diatom-inferred total phosphorus and electrical conductivity for Lake Tavatui (Middle Urals, Russi) over the last 11.7 cal ka BP

“…Quantitative reconstructions of lake water parameters were obtained based on the diatom inference models developed by simple weighted averaging and weighted averaging partial least squares methods. For electrical conductivity reconstructions, a transfer function developed using a 72-lake regional diatom dataset was applied [5] . For total phosphorus reconstructions, a combined TP diatom dataset from the European Diatom Database Initiative (EDDI) [ 6 – [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] ] was used.…”

Sediment Mikrobiyal Yakıt Hücrelerinde Bakır ve Grafit Katot Elektrotların Kullanımı

“…Daha önceki çalışmalarla kıyaslandığında, sediment mikrobiyal yakıt hücrelerinin elektriksel güç çıkışlarını arttırmak için grafit, titanyum, titanyum oksit gibi malzemeler kullanmak yerine bakır katot malzemesinin kullanılmasının daha doğru bir strateji olduğu apaçık ortaya çıkmıştır. Önceki çalışmalarda sediment malzemenin, elektriksel iletkenliği 55-3780 µS/cm, PH değeri 6.91-9.4, toplam çözünmüş katı 120-1400 mg/L, tatlı sudaki tuzluluğu 0-0.5 ppt ve kuru kütle yoğunluğu en fazla 1.6 g/cm 3 olarak ifade edilmiştir [13][14][15][16]. Tablo 1'deki verilerin önceki çalışmalarla uyumlu olduğu ve kullanılan sediment malzemesinin sediment esaslı mikrobiyal yakıt hücreleri için uygun bir organik malzeme olduğu anlaşılmaktadır.…”
