TL;DR: In this paper, the most effective coordination factors were ranked based on the relative importance index (RII) such as Scheduling, Quality assurance plan, and all parties participation in plans, which have fulfilled the research gap and provided better management and higher performance for project parties.
Abstract: Construction projects performance requires improvement to fulfil the complexity of the stakeholders’ needs and expectations. Coordination process is proposed as an efficient solution for weak performance of construction projects. Therefore, coordination factors are vital in ensuring a successful implementation of all project phases. This study aimed to identify and prioritise coordination factors that influence the performance of building projects in Malaysian context. A vast body of literature on coordination process was reviewed and resulted in 53 coordination factor. Three rounds of Delphi technique were conducted. The most effective coordination factors were ranked based on the Relative Importance Index (RII) such as Scheduling (RII = 0.97), Quality assurance plan (RII = 0.93), and all parties’ participation in plans (RII = 0.89). These coordination factors have fulfilled the research gap and provided better management and higher performance for project parties. The results offer insightful perspectives to define the most effective coordination factors, for addressing the dependency between project tasks and the parties to enhance project performance.

TL;DR: In this article, the authors used expandable graphite, ammonium polyphosphate, melamine, and boric acid to construct an intumescent fire-retardant coating.
Abstract: Intumescent coating is an insulating material designed to decrease heat transfer to a substrate structure. The coating presented in this research article was based on expandable graphite, ammonium polyphosphate, melamine, and boric acid. Bisphenol A epoxy resin BE-188 was used as a binder with ACR hardener H-2310 polyamide amine. Different formulations were developed to study the effect of expansion and heat shielding after fire testing. The coating was tested at 950°C for 1 h. The results show that the coating was stable and well bonded with the substrate. The coating was characterized with thermogravimetric analysis (TGA, Parkin Elmer, Norwalk, CT, 06859, USA), Fourier transform infrared (FTIR, Nicolet 400 D Shimadzu spectrometer) spectroscopy, X-ray diffraction (XRD, Bruker D8 advance Diffracto meter, Bruker Germany), and scanning electron microscopy (SEM, Carl Zeiss Leo 1430VP, UK). The morphology of char was studied by SEM on the coating after fire testing. XRD and FTIR spectroscopy showed the presence of graphite, boron phosphate, boron oxide, and sassolite in the residual char. TGA (Pyris 1, manufactured by Parkin Elmer, Norwalk, CT, 06859, USA) and differential thermal gravimetric analysis (DTGA) showed that boric acid enhanced the residual weight of the intumescent fire-retardant coating. © 2012 Wiley Periodicals, Inc.

TL;DR: In this paper, a review of recent technological advancements and major problems in polymeric membranes is reported, and techniques to overcome the major problems of polymeric polymers are reviewed, including cross-linking and thermal treatment.
Abstract: Removal of CO2 from natural gas is necessary to purify the gas and to enhance its calorific value. Membrane technology is an efficient technique for CO2 removal due to its ease of operation and low cost. Polymeric membranes exhibit excellent separation performance which is affected by plasticization and swelling in the membrane. Recent technological advancements and major problems in polymeric membranes are reported in this review. Separation performance of polymeric membranes is highlighted in terms of permeability and selectivity. Moreover, techniques to overcome the major problems in polymeric membranes are reviewed. Commonly, cross-linking and thermal treatment are used to minimize the effect of plasticization and swelling in the membrane. For future perspectives, there is a need to find more efficient methods to overcome these problems.
