The phenotypic plasticity of plant is related to the ability to adapt its anatomy and morpho-functionality to environmental changes and it is expressed mainly by organs used for the uptake of resources, as leaves and roots (Smilauerova et al. 2002). Therefore the complexity and variability of radical system is the outcome of the root adaptation to soil heterogeneity (Waisel et al. 2002). Many a...

While the zebrafish is commonly used for studies of developmental biology and toxicology, very little is known about their osmoregulatory physiology. The present investigation of Na(+) and Cl(-) transport revealed that the zebrafish is able to tolerate extremely low ambient ion concentrations and that this is achieved at least in part by a greatly enhanced apparent uptake capacity and affinity ...

Composting is the best-known processes for biological stabilization of sewage sludge, municipal solid waste and other biodegradable wastes. Prepared compost can be used as a soil conditioner in agricultural applications. However, the presence of non-biodegradable and high level of toxic heavy metals in the compost frequently hinders agricultural land application. Uptake of heavy metals by plant...

Radiolabeled porphyrins are potential tumor avid radiopharmaceuticals because of their impersonation in the human body, ability to complex various radionuclides, water solubility, low toxicity etc. In this work a radiogallium porphyrin complex has been developed. [(67)Ga] labeled 5,10,15,20-tetrakis(3,4-dimethoxyphenyl) porphyrin ([(67)Ga]-TDMPP) was prepared using freshly prepared [(67)Ga]GaCl...

Affinity layers play a crucial role in chemical sensors for the selective and sensitive detection of analytes. Here, we report the use of composite affinity layers containing Metal Organic Frameworks (MOFs) in a polymeric matrix for sensing purposes. Nanoparticles of NH2-MIL-53(Al) were dispersed in a Matrimid polymer matrix with different weight ratios (0-100 wt %) and drop-casted on planar ca...

In this study, water and nutrient uptake from the substrate and responses of the crop to fertigation strategies were analysed. In an experiment and simulation study, the amount and frequency of fertigation and electrical conductivity (EC) of the fertigation water were changed for a tomato crop grown on rockwool. In a climate chamber, tomato plants were grown on rockwool while five different EC ...

Research goal: This article presents the results of a research project aimed at demonstrating effects and benefits using an organic ingredient, hydrogel (Hydro Start), that can improve germination growth Zea mays Solanum lycopersicum seedlings. Materials Methods: Experiments began in April 2022 were conducted greenhouses CREA-OF Pescia (PT) on seeded plants lycopersicum. Seeds placed pots with ...

We studied nutrient uptake in relation to water chemistry, stream hydrodynamics, and ecosystem metabolism in two eutrophic lowland streams located near Berlin, Germany. Ambient nutrient uptake rates ranged from 0.180 to 12.880 g NO3-N m22 d21, from 0.035 to 0.517 g NH4-N m22 d21, and from 0.017 to 0.750 g PO4-P m22 d21. Temporal and spatial variability in nutrient uptake rates within single str...
