The work described in this paper is to demonstrate the productiveness of implementing Last Planner System to improve construction planning process in an Institutional building construction project in India. The Last Planner System (LPS) has been implemented on construction projects to increase work flow reliability, improve productivity, greater collaboration with field personnel and sub contractors, and completing the project within the stipulated duration and carrying out smooth workflow. Consequently, this research centered on improving building construction processes in India, reports the findings from the implementation of the Last Planner System on an Institutional building construction projects in India. The initial state of production plan reliability within the project was observed to be highly unreliable with a high degree of variability. However as the implementation commenced, production plans were stabilized with an improved reliability in the schedules. The results from this study demonstrate that although an Institutional building construction process is a linear process, a number of benefits were still recorded in terms of improving construction planning and organizing processes, during the implementation. © Research India Publications.

Nickel(II) and zinc(II) complexes were synthesized from bidentate isomeric pyridyl tetrazole ligands such as 2-(1-vinyl-1H-tetrazol-5-yl)pyridine (L1), N,N-dimethyl-3-(5-(pyridin-2-yl)-1H-tetrazol-1-yl)propan-1-amine (L2), 2-(2-vinyl-2H-tetrazol-5-yl)pyridine (L3), N,Ndimethyl-3-(5-(pyridin-2-yl)-2H-tetrazol-2-yl)propan-1-amine (L4). All the complexes were characterized in the light of elemental analysis, FTIR, UV-visible and magnetic studies. The spectroscopic data suggested that, the ligands act as neutral and monobasic bidentate ligands and form octahedral complexes with general formula [M(L1-4)2Cl2] (M = Ni(II) and Zn(II). The isomeric pyridyl-tetrazole derivative ligands and their Ni(II) and Zn(II) complexes have also been screened for their antibacterial (Bacillus subtilis, Staphylococcus aureus, Proteus vulgaris) and antifungal activities (Aspergillus Niger, Candida albicans) by MIC method.

A novel series of Co(II) complexes of the type Co(L1)Cl2 (1), Co(L2)Cl2 (2), Co(L3)Cl2 (3), Co(L4)Cl2 (4) were prepared with biologically active isomeric pyridyl-tetrazole ligands such as N, N-dimethyl-2-[5-(pyridin-2-yl)-1H-tetrazol-1-yl]ethanamine (L1), N, N-dimethyl-2-[5-(pyridin-2-yl)-2H-tetrazol-1-yl]ethanamine (L2), 2-[5-(pyridin-2-yl)-1H-tetrazol-1-yl]ethanol (L3), 2-[5-(pyridin-2-yl)-2H-tetrazol-2-yl]ethanol (L4) and CoCl2.H2O. in 1:1 metal ligand ratio. These complexes were characterised by elemental analysis, UV-Vis, IR, 1H, 13CNMR and mass spectral studies. EPR spectra of 1-4 cobalt complexes are characteristic of square planar geometry, DNA binding studies were carried by UV-Vis absorption, viscosity and thermal denature studies revealed that each of these complexes are avid binders of calf thymus DNA. The nucleolytic cleavage activities of complexes were carried on double stranded pBR322 circular plasmid DNA by using a gel electrophoresis experiment under various conditions, where cleavage of DNA takes place by oxidative free radical mechanism (·OH).

Mobile Ad-Hoc Network is widely used network. It has many applications like military applications, search and rescue operations, conferences, law enforcement, etc. Most of these applications use multicasting protocol in Mobile Ad-Hoc Network (MANET). Initially Conventional flat multicasting protocols were used. A team affinity model has been used in this protocol wherein the multicast tree consists of teams, rather than individual nodes, and proved scalable and efficient for large scale mobile ad hoc networks. But it has some drawbacks (i.e.) Conventional flat multicasting protocols does not scale well to network size and are not suitable for team multicasting in large scale mobile ad hoc networks. In order to overcome these key problems of scalability to large membership as well as network size and fault tolerance to link/node failures. We propose a new protocol namely Fault Tolerant Hierarchical Multicast Routing Protocol (denoted as FTHMRP) which aims to develop a hierarchical multicast routing protocol based on hypercube architecture for team multicast with fault tolerance. FTHMRP constructs a hierarchy of team leaders and provides fault tolerant multicasting for data sensitive large scale mobile ad hoc networks. Simulation study shows that, FTHMRP provides efficient and reliable multicast compared with the application of a flat multicast scheme (ODMRP) that does not exploit team coordinated motion. © 2013 IEEE.
