Ring-linear blends composed of complexes bearing multiple rings are promising candidates for soft devices, and understanding the penetration linear chains into is essential enhancing their mechanical properties. Coarse-grained molecular dynamics simulations ring-linear bonded or polycatenanes two three were performed revealing conformations in blends. To investigate relationship between ring po...
A local anaesthetic block of branches of the greater auricular and auriculotemporal nerves was used to facilitate the extraction of retained butterfly backs and ear-ring studs. A total of 28 ear blocks were performed on 26 patients. Two patients required bilateral ear blocks, and 17 earlobes were infected. Complete analgesia was obtained in 25 cases, and two patients complained of tolerable dis...
in this work, we define a fuzzy soft set theory and its related properties. we then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.
PURPOSE Evaluate contact lenses fitting after intracorneal ring implantation for keratoconus, its visual acuity and comfort. METHODS Retrospective study of patients undergoing contact lenses fitting, after intracorneal ring for keratoconus. The criterion for contact lens fitting was unsatisfactory visual acuity with spectacle correction as referred by the patients. All patients were intoleran...
in this paper, based in the l ukasiewicz logic, the definition offuzzifying soft neighborhood structure and fuzzifying soft continuity areintroduced. also, the fuzzifying soft proximity spaces which are ageneralizations of the classical soft proximity spaces are given. severaltheorems on classical soft proximities are special cases of the theorems weprove in this paper.
A novel norditerpenoid, horiolide (1), has been isolated from an Indian Ocean soft coral of the genus Sinularia. The structural elucidation was achieved by a study of its spectral characteristics. This compound is structurally characterized by a new carbon skeleton having one six-membered cyclohexane ring bearing an isopropylene moiety, a carbonyl group, and one seven-membered ring attached to ...
A molybdenum/silicon multilayer-coated 1:1 ring-field optic with a numerical aperture of 0.0835 is used to carry out soft-x-ray projection imaging with undulator radiation at 12.9 nm. An ideal optic of this type should be able to image 0.1-µm features with a contrast exceeding 90% at this wavelength. The useful resolution of our ring-field optic is experimentally found to be approximately 0.2 µ...
The aluminium ring pulls associated with the latest designs of drinks cans can be relatively easily detached from their mounting on the top of the can and subsequently aspirated. Their small size predisposes them to lodge as foreign bodies (FBs) in the throat. The similarity of atomic number between soft tissue (7.5) and aluminium (13) makes detection of these FBs difficult on soft tissue radio...
A 48-year-old man accidently swallowed the ring pull from a soft drink can. He complained of pain in his chest. Chest radiographs were normal. A metal detector emitted a strong response when passed across the front of his chest. Oesophagoscopy was carried out and the ring pull was successfully removed. We recommend the wider use of metal detectors by accident and emergency (A&E) department staf...
