Chenille Yarn

This study examines the twist design of chenille yarns from theoretical consideration. Four kind of chenille yarns were selected for practice validation. The results indicate that there was little deviation between the twist under theoretical approach and the actual tested values; linear density of centre yarn and pile yarn, pile yarn density have significant effects on the twist design of chenille yarns.

Recently we have developed a form of polarization microscopy that forms images using optical properties that have previously been limited to macroscopic samples. This has given us a new window into the distribution of structure on a microscopic scale. We have coined the name differential polarization microscopy to identify the images obtained that are due to certain polarization dependent effects. Differential polarization microscopy has its origins in various spectroscopic techniques that have been used to study longer range structures in solution as well as solids. The differential scattering of circularly polarized light has been shown to be dependent on the long range chiral order, both theoretically and experimentally. The same theoretical approach was used to show that images due to differential scattering of circularly polarized light will give images dependent on chiral structures. With large helices (greater than the wavelength of light) the pitch and radius of the helix could be measured directly from these images.

AbstractThe toxic leadership refers to destructive behaviours and leaders’ personal characteristics which cause serious damage to the subordinates and organizations. Still, what is toxic for the military in one country can be good in another one, given the cultural differences. This article wants to emphasize, from a theoretical approach, the main characteristics and effects of toxic leadership within the military organization.

<p>Protein folding is strictly related to the determination of the backbone dihedral angles and depends on the information contained in the amino acid sequence as well as on the hydrophobic effect. To date, the type of information embedded in the amino acid sequence has not yet been revealed. The present study deals with these problematics and aims to furnish a possible explanation of the information contained in the amino acid sequence, showing and reporting rules to calculate the backbone dihedral angles φ. The study is based on the development of mechanical forces once specific chemical interactions are established among the side chain of the residues in a polypeptide chain. It aims to furnish a theoretical approach to predict backbone dihedral angles which, in the future, may be applied to computational developments focused on the prediction of polypeptide structures.</p>
