Fabrication of Defect-Free Cellulose Acetate Hollow Fibers by Optimization of Spinning Parameters
Spinning of cellulose acetate (CA) with the additive polyvinylpyrrolidone (PVP) in N-methyl-2-pyrrolidone (NMP) solvent under different conditions was investigated. The spinning parameters of air gap, bore fluid composition, flow rate of bore fluid, and quench bath temperature were optimized based on the orthogonal experiment design (OED) method and multivariate analysis. FTIR and scanning elec...
متن کاملAkin osteotomy: good staple positioning
Akin osteotomy is a common component of hallux valgus surgery. Holding the osteotomy in good position with a well placed staple can prove difficult. To aid this, a marker pen is used to apply ink to the tip of the proximal limb of the staple (Fig 1). A hole is drilled in the distal bone and the non-inked staple limb is inserted while the osteotomy is held in the desired position. This causes tr...
متن کاملA Tutorial Introduction to STAPLE
Introduction STAPLE is an expectation-maximization algorithm for Simultaneous Truth And Performance Level Estimation. The algorithm considers a collection of segmentations and computes a probabilistic estimate of the hidden, implicit, true segmentation and a measure of the performance level achieved by each segmentation. The source of each segmentation in the collection may be an appropriately ...
متن کاملBiofortification of Staple Food Crops: Six Questions
More than half the world’s population suffers from micronutrient malnutrition. Biofortification of staple food crops is a new public health approach to control vitamin A, iron, and zinc deficiencies in poor countries. Biofortification is the development of micronutrient‐dense staple crops using traditional breeding practices and modern biotechnology. It has multiple advantages: it capitalizes o...
متن کاملKnot spinning
This exposition is intended to provide some introduction to higher-dimensional knots embeddings of Sn−2 in S through spinning constructions. Once our shoe laces, those archetypical hand tools of knot theory, have been turned into spheres, how can we construct and visualize concrete examples of such knots? There are many important ways to construct higher-dimensional knots. If we are interested ...
