A model for direct dragline casting in a dipping coal-seam
(SOUTH AFRICAN INST MINING METALLURGY, 2004)
This article introduces a computer model, which emphasizes panel design for draglines deployed in direct side-casting mode. The study covers flat and inclined coal-seam conditions with the dragline operating along the ...
Could prolactin receptor gene polymorphism play a role in pathogenesis of breast carcinoma?
(LIBRAPHARM, 2004)
Objective: Constitutive activation of various hormone and growth factor receptors is newly recognised as a common cause of tumour development. This study investigated the presence of any mutation or polymorphism of prolactin ...
Preparation and thermomechanical characterization of poly(vinyl chloride) blends compatible with terpolymer-containing maleic anhydride
(JOHN WILEY & SONS INC, 2004)
In this study, I aimed to change the thermomechanical characteristics of poly(vinyl chloride) (PVC), which is widely used in commercial areas. Copolymers containing maleic anhydride (MA) units are commonly used to obtain ...
