Under the global climatic changes and anthropogenic impacts on environment, information about characteristics specific features of soils in remote regions as Antarctica is valuable could be used references. This study focuses analyses original data physico-chemical composition micromorphological structure Cryosols, collected 2019 from sampling area Bulgarian Antarctic Base “St. Kl. Oh...

the purpose of this study was comparison of applicability of tertiary treatment of tehran domestic sewage with organic and inorganic coagulants or a combination of them. the far test procedure was applied utilizing: alum, polyelectrolyte wt 2600, anionic polyelectorlyte wt 3000, and nonionic polyelctrolyte wt 2690 as organic coagulants (products of calgon). the combination of lime with each of ...

Zanthoxylum nitidum (Roxb.) DC (Rutaceae), called Tez-mui in Assamese, is a large prickly shrub, and its stem bark is ethnomedicinally prescribed in North-East India for treatment of various disease conditions like toothache, gingivitis, fever, colic vomiting, diarrhoea and cholera. Scientific parameters are not yet available to identify the exact plant material and to ascertain its quality and...

Integration of new natural fibers in polymer composites field can contribute to increase the production of natural reinforcements and expand their use into new applications. In the present work, new cellulosic fibers were extracted from Lygeum spartum L. plant using an eco-friendly method. The morphological, physico-chemical, thermal and mechanical properties of L. spartum L. fibers were report...

Hydroxyapatite nanoscale particles (nHA) were prepared by wet chemical precipitation using four different synthesis methods. Differences in physico-chemical properties including morphology, particle-size, and crystallinity were investigated following alteration of critical processing parameters. The nanoparticles were also studied using X-ray diffraction (XRD), Fourier Transform infrared spectr...

In the course of our continuing search for antifungal antibiotics from microbial sources, we found an antifungal antibiotic against phytopathogenic fungi, especially Alternaria sp. from Actinomycete strain NPO-101. In the present report, we describe fermentation, isolation, physico-chemical properties, structure elucidation, and biological activities of NP-101A. The producing organism, strain N...
