The alpaca is the most important fiber producer of the South American camelid species, and is an important source of income for the Andean communities. Nowadays, fiber diameter is considered the main selection objective in alpaca populations throughout the world. However, fiber diameter increases with the age of the animals, and it would be preferable to select those animals that maintain a thi...

in this work, cofe2o4 nanoparticles have been prepared by co-precipitation technique. the synthesized cofe2o4 nanoparticles were applied in the preparation of cofe2o4/polyacrylonitrile fiber nanocomposites by the electrospinning process. the prepared nanoparticles and nanofibers were characterized using the scanning electron microscopy (sem) and x-ray diffraction methods. the results manifested...

introduction: post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. recently fiber reinforced composite posts (frc post) have been used in the treatment of endodontically treated teeth. because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...

objective(s): in this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  materials and methods: paclitaxel (ptx) loaded polylactic acid (pla) nanofibers were prepared by electrospinning. the effects of process parameters, such as ptx concentration, tip to collector distance, voltage, temperature and flow rate...

Peripheral nerve cross sections were analyzed for the variation in peripheral nerve histograms obtained along a single short segment of cat saphcnous nerve. Individual myelinatcd fibers in one fasciclc were traced through nine sequential sections. Two mean fiber diameter histograms were obtained from the sequential cross sections : a “mean fiber diameter histogram” constructed from the arithmet...

This study was conducted to investigate the hair production and fleece characteristics of hair goats in Fars province. The material of the study included a total data of 84 hair goats, which were between kids and adult in male and female goats, respectively. The overall average for fleece weight, fiber length, staple lengths, washing yield, hair fiber diameter, of fiber diameter, breaking force...
