The paper presents a logboat found by an expedition from the University of Warsaw in Lake Lubanowo (northwestern Poland) during underwater archaeological survey 2020. It is first made beech wood (Fagus sylvatica) registered area Poland. conventional radiocarbon date 2350±30 BP; thus, vessel may be attributed to Jastorf or Pomeranian culture, as it was border between territories both units. Only...

The paper presents a dynamic model illustrating the swing of mobile machine on wheeled chassis equipped with loader crane and anchor outriggers during loading unloading operations. regards interaction effect outrigger anchoring device weak soil within system “load – devices soil”. Possible variants single multiple step compaction changes in its deformation characteristics area implementation ar...

The Americanjoumal a/Occupational Therapy T he proXimal interphalangeal (PIP) joint is particularly susceptible to acute ligamentous injury, and such an injury can result in swelling without ligament laXity, collateral ligament laXity and disruption, or a partial or complete avulsion of the volar plate with or without bony involvement. Many articles have been written about methods for treatment...

The forward kinematics of the Stewart–Gough platform is vital for high-precision positioning and sensing in six degrees freedom. In this paper, solving converted to searching best posture corresponding input outrigger length vectors by inverse kinematic calculation. simulated annealing (SA) process embedded into particle swarm optimization (PSO) improve convergence speed overcome local converge...

Proximal interphalangeal (PIP) flexion contracture is a common complication following hand injuries and conditions. This study investigated the treatment outcome of 20 subjects with PIP flexion contracture who followed a dynamic splinting program using either a Capener or low-profile outrigger. The splint applied a 250-g force to the distal end of the middle phalanx. Each patient was instructed...
