A Distributed Clustering Scheme for Wireless Sensor Networks
Clustering is a promising solution to conserve sensor
energy levels and to organize tasks among nodes. This paper
presents a distri buted energy efficient protocol to cluster wireless
sensor networks ...
Indirect synthesis of Bis-2PhIndZrCl2 Metallocene catalyst used for ethylene polymerization
Bis(2-PhInd)ZrCl2 was simply synthesized indirect via the intermediating bis(2-PhInd)ZrMe2 compound from
2-Phenylindene and four equivalents of MeLi. The final product was achieved by use of halogenating agent
(HCl).This method...
Synthesis of Stereoblock Elastomeric Poly(propylene)s Using a (2-PhInd)2ZrCl2 Metallocene Catalyst in the Presence of Co-Catalyst Mixtures: Study of Activity and Molecular Weight
The effect of adding various aluminumalkyls (R¼Et, i-Bu) on the polymerization of propylene is studied using a (2-PhInd)2ZrCl2 pre-catalyst. A mild deactivating effect is found upon addition of TIBA, whereas TEA shows a sharp deactivating effect...
دیالکتیک ذهن و عین نقدی تحلیلی بر رمان آینه های دردار گلشیری
دیالکتیک ذهن و عین، یعنی به رسمیت شناختن توأمان متافیزیک و واقعیت؛ بدینصورت که هر معرفتی ناشی از مبادلۀ دو جریان ذهن و تجربه است. این دیدگاه فلسفی که قابل توجه فیلسوفان غربی و شرقی بوده، به عرصۀ نظریهپردازی در حوزۀ نقد ...
