The new idea presented in the paper is to reverse of an assembly line in order to allow complete disassembly. A generalised Synchronised Hybrid Petri Nets (SHPN) model based control of an assembly/disassembly mechatronics line (A/DML) served by a wheeled mobile robot (WMR) equipped with robotic manipulator (RM) is presented. The approach is a hybrid one, the assembly/disassembly line being the ...

Decision-making methodologies for evaluating a product’s end-of-life options have become a significant area of research. Extensive work has been carried out in the area of product recovery, e.g. module-based disassemblability, reverse logistics, remanufacturing, material recyclability, among others. Some of these methods use graphical representations in the form of disassembly trees and/or netw...

Elongation factor G (EF-G) promotes the translocation step in bacterial protein synthesis and, together with ribosome recycling factor (RRF), the disassembly of the post-termination ribosome. Unlike translocation, ribosome disassembly strictly requires GTP hydrolysis by EF-G. Here we report that ribosome disassembly is strongly inhibited by vanadate, an analog of inorganic phosphate (Pi), indic...

Focal adhesion disassembly is regulated by microtubules (MTs) through an unknown mechanism that involves dynamin. To test whether endocytosis may be involved, we interfered with the function of clathrin or its adaptors autosomal recessive hypercholesteremia (ARH) and Dab2 (Disabled-2) and found that both treatments prevented MT-induced focal adhesion disassembly. Surface labeling experiments sh...

Nowadays, in modern societies, growing activities in construction affairs and their economic development have been resulted construction wastes and so much demolition in the past three decades. Most of these wastes have not been treated and therefore caused severe damages to the environment. In this research, after reviewing construction and demolition management methods and their accesso...

Disassembly of nuclear pore complexes (NPCs) is a decisive event during mitotic entry in cells undergoing open mitosis, yet the molecular mechanisms underlying NPC disassembly are unknown. Using chemical inhibition and depletion experiments we show that NPC disassembly is a phosphorylation-driven process, dependent on CDK1 activity and supported by members of the NIMA-related kinase (Nek) famil...

OBJECTIVE To review our favorable experience with maxillofacial disassembly for exposure and resection of tumors of the skull base. PATIENTS AND METHODS This is a retrospective review of 31 patients from 1997 to 2005 treated by maxillofacial disassembly and includes 22 patients with midface disassembly and 9 patients with mandible with or without midface disassembly. RESULTS Follow-up range...

Stage 14 Drosophila oocytes are arrested in first meiotic metaphase. A cell-free extract of these oocytes catalyzes apparent disassembly of purified Drosophila nuclei as well as of nuclear lamin polymers formed in vitro from isolated interphase lamins. Biochemically, the oocyte extract catalyzes lamin solubilization and phosphorylation as well as characteristic changes in one- and two-dimension...

We explore a new form of view rewrite called view disassembly. The objective is to rewrite views in order to \remove" certain sub-views (or unfoldings) of the view. This becomes pertinent for complex views which may deened over other views and which may involve union. Such complex views arise necessarily in environments as data warehousing and mediation over heterogeneous databases. View disass...

Disassembly is one of the most time-consuming and labor-intensive activities during value recovery end-of-life (EOL) products. The completion time (makespan) disassembling EOL products highly associated with allocation operators, especially in parallel disassembly. In this paper, asynchronous disassembly planning (APDP), which avoids necessity to synchronize tasks manipulators process, studied ...
