Kinkasi is one of the oil fields of the DR Congo Coastal Basin.It is essentially formed of two main geological units (A and B) in aluminum lotion the Turonian, each composed of a succession of different horizons (Zones) according to the type of siltstone.These two main units contain 6 Zones.Unit A consists of Z6 and Z5 of Coniacian age, while the r
DMR 249A is a micro-alloyed high strength low alloy (HSLA) steel particularly designed for shipbuilding structures due to its excellent strength-to-weight ratio.In this investigation, the rotating-beam fatigue test was performed on the flux-cored arc welded (FCAW) butt joints of DMR 249A steel.And the fatigue test results compared to mechanical pro
In this study, green round poles of Populus nigra L.var.italica were treated with Celcure by using Tire - Tube method.After felling and sizing trees, thick - end of poles (about 15 cm.) were debarked and a section of tire inner Tube was fastened around the debarked end of read more the fresh - cut poles and bound tightly with rubber bands and wilds
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 read more lossless co
