Description:

This volume of the International Letters of Natural Sciences presents to readers the latest research in antioxidant activity of Nepeta nuda and phenolic content; ethanol and water extracts of Nepeta nuda subsp. albiflora were prepared and used for biochemical analyses. Also, readers can find research includes improved soil fertility by Combination of inorganic and organic fertilisers from foliar Application of Banana Pseudostem Sap, which will enhance crop productivity while reducing environmental degradation. Results of studies on the content of artificial (137Cs, 90Sr) and natural radionuclides (226Ra, 232Th, 40K) in tissues and organs of various individuals of pumpkinseed Lepomis gibbosus (Linnaeus, 1758) from the Zaporizhzhia (Dnipro) reservoir. Report of amino acids composition of Thryonomys swingerianus (of Liver, Heart and Kidneys). Ivestigation of evaluated levels of heavy metals namely cadmium, lead, and mercury from key aquatic fauna and sediments from seven strategic sections of the Lake Mainit in the Philippines.

ILNS Biostimulation and Overcoming the Abiotic Stresses in Plants

Online since: August 2019

Description: The research articles published in the special issue "Biostimulation and Overcoming the Abiotic Stresses in Plants" provides useful information on the various mechanisms that perform biostimulants on the level of components of the antioxidant defense system, including low molecular weight antioxidants and antioxidant enzymes activities, induced by various biostimulants. We hope this special issue will be interesting and useful for specialists in the area of biostimulation of plants growth.

Description:

This volume of the International Letters of Natural Sciences presents the latest investigations concerned with the evaluation of the amino acid profiles of the male and female innards of samples of spotted porcelain crab (Neopetrolisthes maculatus (H. Milne-Edwards, 1837) as well as estimation of the total hydrocarbon and heavy metals in the body of the West African red mangrove crab (Goniopsis pelli (Herklots, 1851); designing of a new chimeric INaV/N-DPFase protein of Pseudomonas syringae and examination of its binding with Didoprpopyl-Fluorophosphate. There are also presented the comparative analysis of climate-smart technologies as tools for improving water productivity in an enormous water use rice-wheat system of South-Asia and the first report from Neyveli Lignite Formation about the charcoalified wood of Hopenium pondicherriensis (Dipterocarpaceae).
