The Significant Structure Theory Applied to Amorphous and Crystalline Polyethylene

The significant structure theory applied to liquid oxygen.

The significant structure theory applied to a mesophase system.

The significant structure theory of liquids is extended to the mesophase system with p-azoxyanisole as an example. This compound has two different structures, a nematic phase and an isotropic phase, in its liquid state. In this study the nematic phase is treated as subject to a second volume and temperature-dependent degeneracy formally like that due to melting. The isotropic phase is treated a...

Non-Gaussian behavior of crystalline and amorphous phases of polyethylene

We report on measurements of the incoherent elastic neutron-scattering intensity Iel(Q) of polyethylenes with degrees of crystallinity 0.46 and 0.96 in a wide Q ~length of scattering vector! range from 0.4 to 6.2 Å to observe the deviation from the Gaussian behavior. The non-Gaussian behavior was observed in both the amorphous and the crystalline phases. The non-Gaussian behavior in the theoret...

The significant structure theory of liquids applied to the shock compression of argon.

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
