Experimental investigation of a highly efficient, low-cost PVC-Rollers Sandwich (PVC-RS) seismic isolation

Experimental PVC Material Challenge in Subjects with Occupational PVC Exposure

BACKGROUND Polyvinyl chloride (PVC) materials have been linked to asthma in several epidemiologic studies, but the possible causal factors remain unknown. PARTICIPANTS We challenged 10 subjects experimentally to degraded PVC products under controlled conditions. All of the subjects had previously experienced respiratory symptoms suspected to be caused by this kind of exposure in their work pl...

PVC Sewer System Seismic Analysis Made Practical

MSC is announcing a new business offering based upon a breakthrough technology. MSC has developed a means by which design engineers or occasional CAE software users can reliably perform complex engineering analysis with the same resultant quality as do the dedicated analysis experts. This breakthrough technology captures the expert’s engineering knowledge and specific process solution methodolo...

Chemical Modification of Pvc

The degradation of PVC at a processing temperature is mostly caused by its abnormal and unsta— ble molecular structures. It has been pointed out that its allyl chloride structures play a significant role as the abnormal and unstable structures. Inasmuch as the allyl chloride struc— tures are markedly more chemically active than the normal structure, the selective chemical treatments are applica...

An Evaluation of the Cost of Incinerating Wastes Containing Pvc

An Efficient PVC-based Handoff Control in Wireless ATM Networks

In this paper, we investigate the issue of extending ATM technology to wireless networks. The PVC(Permanent Virtual Connection)-based handoff scheme is proposed to support the integration of the wireless and wireline networks. Without re-establishing procedure, a mobile connection can be handed over to a new base station through PVC which are reserved for handoff between neighboring mobility-en...
