Nature of Bound Water in Colloidal Systems.
The state of water in colloidal systems is a controversial subject. Discovery of the colloidal state by GRAHAM (18) was followed by extensive studies by VAN BEMMELN (66, 67, 68, 69) and ZSIGMONDY (73, 74). Thermodynamic studies by KATZ (36) indicated significant changes in free energy and heat content in colloidal systemis at low water content. OVERTON (51) concluded that part of the water in a...
متن کاملOrganic nature of colloidal actinides transported in surface water environments.
Elevated levels of (239,240)Pu and 241Am have been present in surficial soils of the Rocky Flats Environmental Technology Site (RFETS), CO, since the 1960s, when soils were locally contaminated in the 1960s by leaking drums stored on the 903 Pad. Further dispersion of contaminated soil particles was by wind and water. From 1998 until 2001, we examined actinide ((239,240)Pu and 241Am) concentrat...
متن کاملThe nature of the colloidal 'glass' transition.
The dynamically arrested state of matter is discussed in the context of athermal systems, such as the hard sphere colloidal arrest. We believe that the singular dynamical behaviour near arrest expressed, for example, in how the diffusion constant vanishes may be 'universal', in a sense to be discussed in the paper. Based on this we argue the merits of studying the problem with simple lattice mo...
متن کاملBound Water in Muscle
1. The amount of free unfrozen water, i.e. water acting as normal solvent, in frog's muscle at temperatures below the initial freezing-point has been calculated from the vapour pressure isotherm of the muscle. 2. Significant amounts of free water are present at -20 degrees C. The total amount of unfrozen water at -20 degrees C. cannot, therefore, be taken as a measure of the bound water in musc...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
