Exploring Antimalarial Activity of Chalcone Derivatives through QSAR
Abstract: Background: The core structure of chalcones contains a reactive α,β-unsaturated system within the aromatic rings, which plays a key role in mediating various biological effects. These effects include enzyme inhibition, anticancer activity, anti-inflammatory properties, as well as antibacterial, antifungal, antimalarial, antiprotozoal, and anti-filarial actions.Modifying the structure by introducing substituent groups to the aromatic ring can enhance potency, reduce toxicity, and expand their range of pharmacological actions.Methods: A total of twenty-seven …

Prediction Of Compression Index For Lateritic Soil Using Transformed Variable
Abstract: The information on the compression index of a soil is vital in geotechnical design, but its determination is expensive and time consuming. Most models relating compression index and basic soil properties are usually based on soil types. This work seeks to develop a model relationship between compression index and basic soil properties for lateritic soils. Selective transformation method which involves testing some general functional forms, to choose the model that …

Studies on Removal of Coomassie Brilliant Blue R250(CBB) dye Usingligninas Adsorbent
Abstract: Coomassie brilliant blue R-250 (CBB), an organic dye present in wastewater effluent, affects environment by reducing the photosynthetic activity in aquatic ecosystems. CBB must be eliminated from effluent as a result. In the present study, lignin was utilized as a low-cost bio adsorbent for the removal of CBB dye employing an adsorption technique in order to minimize pollution caused by CBB dye. By studying the effect of several parameters includes …
