Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 905-911 doi: 10.1007/s11783-015-0786-x

Abstract: nano-silicon (Si) and common Si on lead (Pb) toxicity, uptake, translocation, and accumulation in the riceThe results showed that Si application alleviated the toxic effects of Pb on rice growth.Pb concentrations in rice grains treated with common Si and nano-Si decreased by 21.3%–40.9% and 38.6%growth, preventing Pb transfer from rice roots to aboveground parts, and blocking Pb accumulation inrice grains, especially in high-Pb-accumulating rice cultivars and in heavily Pb-polluted soils.

Shear design of high strength concrete prestressed girders

Emad L. LABIB,Hemant B. DHONDE,Thomas T. C. HSU,Y. L. MO

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 4,   Pages 373-387 doi: 10.1007/s11709-014-0087-7

Abstract: Normal strength prestressed concrete I-girders are commonly used as the primary superstructure components in highway bridges. However, shear design guidelines for high strength PC girders are not available in the current structural codes. Recently, ten 7.62 m (25 feet) long girders made with high strength concrete were designed, cast, and tested at the University of Houston (UH) to study the ultimate shear strength and the shear concrete contribution ( ) as a function of concrete strength ( ). A simple semi-empirical set of equations was developed based on the test results to predict the ultimate shear strength of prestressed concrete I-girders. The UH-developed set of equations is a function of concrete strength ( ), web area ( ), shear span to effective depth ratio ( / ), and percentage of transverse steel ( ). The proposed UH-Method was found to accurately predict the ultimate shear strength of PC girders with concrete strength up to 117 MPa (17000 psi) ensuring satisfactory ductility. The UH-Method was found to be not as overly conservative as the ACI-318 (2011) code provisions, and also not to overestimate the ultimate shear strength of high strength PC girders as the AASHTO LRFD (2010) code provisions. Moreover, the proposed UH-Method was found fairly accurate and not exceedingly conservative in predicting the concrete contribution to shear for concrete strength up to 117 MPa (17000 psi).

A Standard for the Commissioning Process

William L. Gillis,Elizabeth A. Cudney

Frontiers of Engineering Management 2015, Volume 2, Issue 1,   Pages 39-51 doi: 10.15302/J-FEM-2015006

Abstract: The demand for commissioning services for new-building construction projects is experiencing rapid growth. Commissioning (Cx) is touted as being a quality-focused process for ensuring the owner’s project requirements (OPR) are met by design, final construction, and the operations of a building. To an owner this is just what is needed to receive a perfect building at occupancy. However, as many owners have realized, the Cx process does not guarantee the completed building will be what was expected. It should be pointed out that this is typically not caused by the Cx process, but the Cx process should or could have identified, in the early phases of the project, many of the issues that made it through to the completed building. There are a number of reasons why the Cx services received may not be optimal. Often it is poor communication and the transfer of knowledge between project teams. Cx should and can facilitate both communication and the transfer of knowledge from phase to phase. An adaptation of the quality function deployment (QFD) four-phase model can accomplish this by filling the gaps among the major Cx activities and provide a standard approach to the process. The four-phase model effectively links each of the Cx activities to each other and back to the OPR, providing a method for improved communication and knowledge transfer. This paper investigates some potential reasons for inconsistent Cx services, presents an argument for the need of a Cx standard, and proposes a potential standard.

Quality Function Deployment Implementation in Construction: A Systematic Literature Review

Cudney,William L. Gillis

Frontiers of Engineering Management 2016, Volume 3, Issue 3,   Pages 224-230 doi: 10.15302/J-FEM-2016036

Abstract: The construction of new buildings represents a significant investment. The goal of new building construction is to maximize value and minimize cost while staying on time and within budget. Translating customer requirements into engineering terms for new construction design is vital for a construction project to be successful. Quality function deployment has been successfully used in product development to capture the voice of the customer and translate it into engineering characteristics. Quality function deployment then carries these parameters into production and service to ensure the voice of the customer is being met with the final product. The house of quality, a tool within quality function deployment, can provide a means for comparison of owner’s project requirements and the proposed design, along with identifying how the design decisions impact meeting customer requirements and green building requirements. Quality function deployment can effectively link the project phases through design and construction and into operations and maintenance to ensure the owner’s project requirements are met with the final building. This research identifies and categorizes studies of quality function deployment applications in construction. The research method used is a systematic literature review from databases related to quality function deployment in the construction industry published in the periodicals through 2016. The principal findings of implementations, practices, and integrated approaches are then summarized. This article intends to propel further research of quality function deployment in the construction sector.

Antifungal and antibacterial functions of medicinal leech recombinant destabilase-lysozyme and its heated-up derivative

PAVLOVA, L. L. ZAVALOVA, I. P. BASKOVA

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 2,   Pages 203-209 doi: 10.1007/s11705-012-1277-2

Abstract: Antifungal activity of recombinant medicinal leech destabilase-lysozyme (rec.Dest-Lys) was investigated by using fungi: , and , including yeasts and . Its antibacterial activity was investigated on gram-negative bacteria . These activities were assessed by radial agar diffusion assay, and scanning and transmission electron microscopy. Therefore, destabilase-lysozyme not only is endo-isopeptidase and lysozyme, but also has antifungal and antibacterial activities. Muramidase activity of rec.Dest-Lys disappeared after heat-treating at 90°C for 50 min without the loss of its antimicrobial activity. Furthermore we showed for the first time that the heated-up derivative of rec.Dest-Lys exhibited more potent activities against the above enumerated fungi and gram-negative bacteria than original protein.
