Research ArticleOpen accessEvery word in the titleEvaluating the Effect of Soil Particle Characterization on Internal Friction AngleArezou Rasti, Hamid Ranjkesh Adarmanabadi, Maria Pineda, Jesse ReinikainenOne of the critical design parameters used in evaluating soil structure is the friction angle, derived from Mohr's Circle failure criterion. The soil friction angle is an engineering parameter estimated in the laboratory to quantify the soil shear strength in geotechnical applications. This paper indicates an experimental study investigating the impact of particle size on different sandy soils shear strength … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 21 Feb 2021 · 8,890 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleThe Characterization of Bacillus thuringiensis from soil habitat of Auky Island, Padaido District in Biak Numfor Regency and Its Toxicity against Mosquito Larva of Anopheles spLantang Daniel, Rampa Ester, Lunga NellyBacillus thuringiensis (Bt) is bacteria that produce protein crystals as an insecticidal against various vector diseases in plants and animals including humans.

Research ArticleOpen accessEvery word in the titleCharacterization of Fungal Communities in Limed and Unlimed Lands Contaminated with Metals: Phospholipid Fatty Acid (PLFA) Analysis and Soil RespirationKassandre Goupil, Kabwe K. Nkongolo, Sabah NasserullaNorthern Ontario (Canada) especially the Greater Sudbury region is highly known for its nickel, copper and other metal deposits. The mining, roasting and smelting of these elements have caused disastrous effects on the vegetation and overall environment. Dolomitic lime which contains calcium and magnesium carbonate was applied to soils from 1980 to 1995 at different locations across Northern Ontario.
