An updated list of Serbian diatom flora – new recorded taxa
(Serbian Biological Society, 2018)
Diatoms are a widespread group of organisms with well-known ecological preferences. Knowledge of their diversity is of great importance for assessing the environmental status of different aquatic ecosystems. The present ...
Uncertainty of using habitat fidelity in biomonitoring based on benthic diatoms - the Raška River case study
(Springer, 2018)
Epilithic diatoms are frequently recommended for river biomonitoring, while much less emphasis is placed on epiphytic communities.
This study considers use of epiphytic and epilithic diatom communities from the Raška River ...
Changes in the diatom community structure and impact on water quality from 2005-2017 - Great Lake (Lurë National Park, Albania)
(Institute of Botany and Botanical Garden 'Jevremovac', 2018)
Great Lake is the largest of the 6 lakes situated in the eastern part of Lura Mountain in the Lurë National Park. Samples were collected in July 2005, June and August 2013 and August 2017. In 2005 and August 2013 epiphytic ...
How do newly-described diatom species affect biomonitoring? – An example of Gomphonema paratergestinum vs. G. tergestinum
(Berlin : Botanic Garden and Botanical Museum, Berlin Freie Universität Berlin, 2018)
Over the past decade a great number of new diatom taxa was described, as well as re-definitions and delimitations of taxa from different species complexes have been performed. The reasons for the constant increase in the ...
Diatoms on the carapace of European pond turtle (Emys orbicularis L.) in Vojvodina
(Institute of Botany and Botanical Garden 'Jevremovac', 2018)
Epibiotic diatoms inhabiting the carapace of European pond turtle (Emys orbicularis Linnaeus, 1758) are examined between May and July 2017 from three locations in Vojvodina (Serbia): Special nature reserve „Deliblatska ...
Proposal for determining the minimum volume of the reservoir for characteristic compressed gases based on the concept of maximum work / Predlog za određivanje minimalne zapremine rezervoara za karakteristične komprimovane gasove na bazi koncepta maksimalnog rada
(Proceedings of 49th International HVAC&R Congress and Exhibition, 2018)
Starting from the main relation for closed thermodynamic systems for maximum work of reverse processes, a general model for determining the minimum volume of the tank containing compressed ideal gases, nitrogen and oxygen, ...
Silicon Thin-Film Solar Cells Approaching the Geometric Light-Trapping Limit: Surface Texture Inspired by Self-Assembly Processes
(American Chemical Society (ACS), 2018)
A new device design of microcrystalline silicon thin-film solar cell allows for approaching the geometric light-trapping limit. The solar cell is based on triangular textured surfaces in combination with optimized front ...
Nanophotonic design of perovskite/silicon tandem solar cells
(Royal Society of Chemistry, 2018)
The perovskite material system allows for the realization of perovskite/silicon tandem solar cells with high energy conversion efficiencies at low cost. To realize such solar cells, the device geometry, the device processing, ...
Corrodive cracks from flux residuals after brazing of thin leaves at an artistic desk lamp / Korozione pukotine od zaostalog topitelja posle lemljenja tankih listova na jednoj umetničkoj stonoj lampi
(Engineering Society for Corrosion, 2018)
Making of an artistic piece usually includes a number of different technologies. It implies that for understanding of eventually present irregularities one should knows a lot of technical details. Brazing technology is one ...
