In this paper, the design and testing of a novel valve for intuitive spatial control soft or continuum manipulators are presented. The is based on style hydraulic flapper valve, but with simultaneous three pressure feed points, which can be used to drive antagonistically arranged actuators positioning robots. variable orifices in rotationally symmetric radial pattern allow an inline mounting co...

Pelvic soft tissue sarcomas are rare tumors often presenting larger than other soft tissue sarcomas and can extend into the thigh through various anatomic routes. Surgical resection is the main modality of curative treatment. En bloc tumor excision with wide, negative margins may reduce the risk of local recurrence. Soft tissue sarcomas extending through the obturator foramen create unique chal...

Unstable pelvic ring disruptions result from high energy trauma and often are associated with multiple concomitant injuries (1–3). Hemorrhage, head injury, pelvic soft tissue trauma (open fractures), and primary system complications are responsible for high mortality rates (4–6). If the patient is hemodynamically unstable the primary goals are to control airways, to establish adequate ventilati...

The title compound, C(21)H(28)O, was isolated from the cytotoxic lipid extract of the Fidjian soft coral Nephthea sp. The steroid showed inhibitory activity to human colon adenocarcinoma SW480 cells (IC(50) = 2.5 µg ml(-1)). The mol-ecular structure indicates that the A ring is almost planar (r.m.s. deviation = 0.032 Å), the B and C rings adopt chair conformations and the five-membered D ring i...

the main purpose of this paper is to introduce and study new classes of soft closed sets like soft regular generalized b-closed sets in soft topological spaces (brie y soft rgb-closed set) moreover, soft rg-closed, soft gpr-closed, soft gb-closed, soft gsp-closed, soft g-closed, soft gb-closed, and soft sgb-closed sets in soft topological spaces are introduced in this paper and we investigat...

This work evaluates the impact of winding system on accuracy soft magnetic material (SMM) characterisation using ring shaped specimen by means finite element simulations. The quantified correlations are validated through measurements. In addition, gained insights discussed and hand guidelines for design said presented.

in this work, we introduce notion of connectedness on fuzzy soft topological spaces and present fundamentals properties. we also investigate effect to fuzzy soft connectedness. moreover, c_i-connectedness which plays an important role in fuzzy topological space extend to fuzzy soft topological spaces.

INTRODUCTION High energy tibial plateau fractures along with calcaneal fractures individually produce several challenges for the orthopaedic surgeon. The principles of bony reconstruction include anatomic reduction and rigid internal fixation of intra-articular fractures and accurate restoration of the coronal, sagittal and transverse mechanical axes. Due to the tenuous nature of the soft tissu...

let r be an associative ring with unity. an element a in r is said to be r-clean if a = e+r, where e is an idempotent and r is a regular (von neumann) element in r. if every element of r is r-clean, then r is called an r-clean ring. in this paper, we prove that the concepts of clean ring and r-clean ring are equivalent for abelian rings. further we prove that if 0 and 1 are the only idempotents...
