Colloidal aggregates of small molecules are the most common artifact in early drug discovery, sequestering and inhibiting target proteins without specificity. Understanding their structure and mechanism has been crucial to developing tools to control for, and occasionally even exploit, these particles. Unfortunately, their polydispersity and transient stability have prevented exploration of cer...

Potentially low-cost continuous carbon fibers are produced from solvated mesophase pitch through a patented meltblowing process. The structural evolution and properties of the fibers are characterized by various analytical methods. The meltblown fibers are continuous fibers which are collected into a fibrous web form, and the diameter of the filaments is attenuated by the flow rate of air strea...

This paper surveys recent progress in fiber spinning technology for reducing polarization mode dispersion with the focus on theoretical understanding of fiber spinning mechanism and features of spun fibers, as well as their applications in fiber spin profiles designs. First, a brief introduction to the requirements of fiber PMD for high-speed optical fiber communications systems is given. Furth...

This paper studies the strategic management of information technology in periods of extreme organizational disequilibrium. In such periods, critical business parameters such as industry positioning, competitive strategies, organizational structures, leadership, and business processes change significantly and simultaneously, thus disrupting the very fundamental bases for strategic IT decisions. ...

Spun fibers are increasingly used in telecommunication systems because their polarization-mode dispersion (PMD) is lower than that in unspun fibers. In this paper, we investigate the effects of a periodic spin on the PMD of fibers with randomly varying birefringence. Numerical simulations show that when the spin period is of the same order as or larger than the beat length, the mean differentia...

silver sulfadiazine is used to prevent and treat infections of second- and third-degree burns. it kills a wide variety of bacteria. in this study silver sulfadiazine was used in gelatin based electro-spun nano-fibers with various drug to polymer ratios (0, 5, 10, 15 and 20 %). sem, edx and ftir analysis showed that the continuous, bead-free, fine fibers containing silver sulfadiazine as an anti...

In recent years, garments made of fabrics with elastane are highly preferred. A garment fabric is able to stretch by about 10-30% and recovery immediately after release. the apparel industry, sewing should not prevent from stretching in woven elastane. The elasticity seams consisting elastic very important. 
 this study, it aimed examine permanent elongation properties different stitch typ...

seed protein quality is an important topic in the production of soybean. the quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. in this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using sds-page and scanning densitometry. the results showed that seed storage protein ba...

We show analytically how periodic spinning affects the polarization mode dispersion of a fiber in three different practical regimes that are determined by the values of three length scales: the beat length, the birefringence correlation length, and the spin period. We determine in which limits the spin is effective in reducing the mean differential group delay.
