This paper introduces a first-order method for solving optimal powered descent guidance (PDG) problems, that directly handles the nonconvex constraints associated with the maximum and minimum thrust bounds with varying mass and the pointing angle constraints on thrust vectors.This issue has been conventionally circumvented via lossless convexificat
Projection Screens The aim of the report was to present the circulation of BVDV (bovine viral diarrhea virus) in the cattle population and determine the cause of the failure of vaccination failure leading to the birth of the PI (persistently infected) calf.The case study was carried out at the BVDV-free animal breeding center and cattle farm, where
2-Keto-3-deoxy-octonate (KDO) is an essential constituent of lipopolysaccharide (LPS) that forms the outermost leaflet of Gram-negative bacterial outer membrane.LPS is mainly composed of lipid A, O-antigen and a core oligosaccharide.Two molecules of KDO are present per one molecule of LPS.A proper level of LPS is required to maintain the outer memb
Low-alloyed TRIP steels are well known since the beginning of the 21st century and used for automotive applications to ensure the passive safety.However, although their behaviour is fully investigated at a monotonous behaviour, the case of cyclic loading is not well studied.The present work describes in detail the heterogeneous-microstructure evolu
