Abstract:

The results of multiyear studies of biogenic element concentrations in the Barguzin River mouth and the Barguzin Bay are presented. The key role of the water outflow dynamics in seasonal and interannual changes in concentrations of biogenic elements and organic carbon in the river and their inflow to the bay is confirmed. The spatial distribution of biogenic element concentrations in the bay depends on seasonal hydrological and geophysical conditions and on the activity of phytoplankton development. It is shown that under low-water conditions in the bay, the concentration of mineral compounds

Biogenic amines are a group of low molecular weight nitrogenous organic compounds that have an important physiological role in cell proliferation, differentiation, and signal transduction. Also, certain biogenic amines act as an important biomarker for the detection of neuroendocrine and cardiovascular disorders in humans. Besides this, the abundance of biogenic amines in food is recognized as a toxin and anti-nutritional element that have several health implications.

Abstract. ‘Sclerites’, described from the surfaces of conodont elements in bedding-plane assemblages by Rhodes and Austin (1985), are shown to be indentations of bladed minerals on the conodont element apatite. Such minerals are seen coating moulds from which conodont elements have been removed, and are identified tentatively as Kaolinite. The recognition of inorganically-produced surface patterns on conodont elements, developed within low thermal régimes, is considered relevant in the light of recent studies of biogenic and metamorphic surface features.

The applications of biogenic lubricating greases to machine elements play important roles in the reduction of friction energy and minimizing wear in a tribological contact, as well as the prevention of environmental pollution.

Model greases were examined using a ball on a disc tribometer at a constant normal force to investigate the friction and wear process according to Fleischer’s energetic wear model.

The geochemistry of dolomite in part of the Thanagazi Formation in the Mesoproterozoic Alwar Basin has been studied employing major and trace elements, including rare earth elements (REEs) to understand their provenance and paleoweathering conditions. In the current study, two distinct types of dolomites were identified viz. amorphous and crystalline. Various geochemical discriminants such as SiO2 vs Al2O3 and CaO vs MgO indicate that the dolomites were originated from sedimentary sources with substantial metasomatic and biogenic contributions.

This thesis investigates how benthic fluxes of phosphorus (P), nitrogen (N), and silicon (Si) change upon oxygenation of anoxic soft bottoms in the brackish, eutrophicated Baltic Sea. Direct measurements in situ by benthic landers demonstrated that fluxes of dissolved inorganic P (DIP) from anoxic bottom sediments in the Eastern Gotland Basin are higher than previously thought (Paper I). It is argued that the benthic DIP flux has a much larger influence on the DIP inventory in the Baltic proper than the external sources. Similarly, benthic fluxes of DIP and dissolved inorganic N (DIN) from ano

Abstract:

The Black Sea, with its oxic, suboxic and anoxic layers, provides a unique environment for studying how biological and geochemical processes affect the composition of particulate matter. The elemental composition of particles in the Black Sea is controlled by their origin and sources. Particles from rivers are dominated by aluminosilicate material that has compositions similar to the earth&rsquo<br>s crust. In general this material is relatively unreactive. Biological processes in the upper oxic and suboxic layers of the water column result in enrichments of elements which used as nutrients. C

Abstract:

The uptake of biogenic elements by spring barley (Hordeum vulgare L.) is significantly influenced by soil moisture, particularly in the arid conditions of Southern Ukraine. Water availability plays a critical role in the solubility of nutrients, their mobility, and the efficiency of root system uptake. Insufficient moisture reduces nutrient availability, disrupts metabolic processes, and negatively affects plant growth and productivity. Understanding the complex relationship between soil moisture content and nutrient uptake is essential for optimizing agronomic practices and improving crop yie

Abstract:

Vistula Lagoon is the second largest lagoon in the Baltic Sea with maximum depth 5.2 m and average depth 2.7 m. Water volume and area are 2.3 km3 and 838 km2. Lagoon is connected with the Baltic Sea by single inlet 400 m wide and 10-12 m deep. Sediment budget estimation were made using literature sources, results of field measurements (hydrology, suspended sediment content, upper layer sediment structure, direct measurements of sedimentation in summer and winter conditions). The budget for terrigene and biogenic components of sediments were made, considering their contributions from the rivers

Abstract:

Lake Arakhley is located within the Lake Baikal basin in Eastern Siberia, Russia. The area is characterized by continental subarctic climate with considerate diurnal temperature range, long cold dry winters and short hot summers with more precipitation occurring during the latter half of the summer. Climatic shifts in high water years and low water years result in morphometric changes in the lake and in the chemical and physical parameters of the ecosystem. During low water years, concentrations of ammonium nitrogen and nitrite nitrogen are decreased, whereas nitrate concentration increases. H
