Amongst the insecticides applied 0.037% Rogor (674 liters/hectare) proved most effective in controlling Lipaphis erysimi Kalt. The next insecticide in effectiveness was found to be 0.025% Parathion (674 liters/hectare). Diazinon, BHC, Malathion and Nicotine Sulphate showed insufficient effect. Zusammenfassung Freilandversuche zur Bekämpfung der Senfblattlaus Lipaphis erysimi Kalt. (Hom.: Aphid.) Von den zur Anwendung gelangten Insektiziden zeigte Rogor 0,038% (674 **l/ha) die beste Wirkung, gefolgt von 0,025prozentigem Parathion (674 ***l/ha). Unbefriedigend blieben: Diazinon, Gamma BHC, Malathion und Nikotin‐Sulfat.

The leg bone that typically undergos the most deformation is the femur. Failures of the femur neck, which are most frequent among human bone failures due to their length and weight, are a very serious issue for people. However, before using biomaterials in implants or any orthopaedic surgery, the right biomaterials must be chosen based on their mechanical and physical properties in comparison to natural bone. The use of biomaterials in the treatment of orthopaedic-related issues is very crucial. By taking into account the mechanical and physical properties of materials, discussions and comparisons of biomaterials are conducted. In comparison to other materials, biomaterials like SS316L, Ti6Al4V, PMMA, and CoCr alloys, magnesium alloys have been found to be a better substitute.
