    Abstract Security has always been a vital research topic since the birth of web application. A great deal of research has been conducted to determine the ways of identifying and classifying security issues or goals However, in the recent years, it has been noticed that high secure web applications have less durability; thus reducing their business continuity. High security features of a web application are worthless unless they provide effective services to the user and meet the standards of commercial viability. Hence, there is a need to bridge the gap between security and durability of the… More >

    Abstract Security is an important component in the process of developing healthcare web applications. We need to ensure security maintenance; therefore the analysis of healthcare web application's security risk is of utmost importance. Properties must be considered to minimise the security risk. Additionally, security risk management activities are revised, prepared, implemented, tracked, and regularly set up efficiently to design the security of healthcare web applications. Managing the security risk of a healthcare web application must be considered as the key component. Security is, in specific, seen as an add-on during the development process of healthcare web… More >

    Durable Aroma Finishing of Wool Fabric with Microencapsulated Vetiver Essential Oil and Assessment of its Properties

    SHALINI RUKHAYA*, NEELAM M. ROSE, SAROJ YADAV

    Journal of Polymer Materials, Vol.38, No.3-4, pp. 179-190, 2021, DOI:10.32381/JPM.2021.38.3-4.1

    Abstract The present study was conducted to develop aroma wool fabric using microencapsulated vetiver essential oil without deteriorating the fabric properties. SEM analysis of the treated wool fabric depicted adhesion of numerous microcapsules of spherical shape and FTIR analysis indicated presence of different functional groups on the fabric. The aroma treatment improved most of the tested physical properties of wool fabric. Aroma treated fabric displayed good antimoth efficacy in terms of weight reduction (7.57%) and moth mortality (40%). Treated wool fabric also exhibited antibacterial activity with 63.45 and 61.37 percent reduction in bacterial growth against S. More >

    Effect of Alkaline Electrolyzed Water on Performance Improvement of Green Concrete with High Volume of Mineral Admixtures

    Guibin Liu1, Meinan Wang2, Qi Yu1, Qiuyi Li2, Liang Wang2,*

    Journal of Renewable Materials, Vol.9, No.11, pp. 2051-2065, 2021, DOI:10.32604/jrm.2021.015398 - 04 June 2021

    Abstract The strength and durability of concrete will be significantly reduced at high volume of mineral admixture, and the poor early strength of concrete also still needs to be solved. In this investigation, a highly active alkaline electrolyzed waters was used as mixing water to improve the early strength and enhance the durability of green concrete with high volume mineral admixture, the influences of alkaline electrolyzed water (AEW) on hydration activity of mineral admixture and durability of concrete were determined. The results showed that compared with natural tap water, AEW can accelerate early hydration process of… More > Graphic Abstract

    Effects of Freeze-Thaw Cycles on Physical and Mechanical Properties of Glulam Exposed to Outdoor Environment

    Ruyuan Yang1, Haitao Li2,*, Assima Dauletbek1,2, Mahmud Ashraf2,4, Rodolfo Lorenzo3, Youfu Sun1, Yuehong Wu1

    Journal of Renewable Materials, Vol.9, No.7, pp. 1293-1307, 2021, DOI:10.32604/jrm.2021.015296 - 18 March 2021

    Abstract This paper presents an experimental investigation to identify suitable indices to assess durability of glulam when subjected to freeze-thaw cycles in an exposed enviroenment. In this study, two types of glulam specimens were tested for their performance when subjected to different levels of aging due to freezing and thawing. Effect of aging treatment on various parameters including thickness swelling rate, static bending strength, elastic modulus, shear strength, and peeling rate of adhesive layer were studied. Obtained results showed that freeze-thaw aging treatment did not affect the water-resistance of the specimens as measured by thickness swelling… More >

    Abstract An offshore long-span continuous rigid-frame bridge is taken as an example to study the effect of degradation of bond-slip behavior on the seismic performance of bridges in an offshore environment during a service period. On the basis of a numerical simulation analysis using the OpenSeeS platform, the influence of durability degradation of concrete carbonization, steel corrosion, and degradation of bond-slip performance is considered collectively using incremental dynamic analysis method to examine the time-varying seismic fragility of the offshore bridge. Results show that when bond slip is considered, the exceedance probability of the bridge components and the… More >

    Effect of Reinforcement Corrosion Sediment Distribution Characteristics on Concrete Damage Behavior

    Fenghua Yuan1, Qing Zhang1,*, Xiaozhou Xia1

    CMC-Computers, Materials & Continua, Vol.58, No.3, pp. 777-793, 2019, DOI:10.32604/cmc.2019.04182

    Abstract Reinforcement corrosion directly affects the mechanical behavior of reinforced concrete structures. An electric corrosion test was conducted on a reinforced concrete test specimen, and a finite element model of the reinforcement corrosion damage was established. In addition, the damage behavior of reinforced concrete under different corrosion sediment distribution characteristics and different corrosion rates was studied. It was noted that when corrosion sediments are in a “semiellipse+semicircle” distribution, the results of numerical calculation are consistent with those obtained experimentally, reflecting the damage characteristics of reinforced concrete test specimens. Further, the results showed that the distribution characteristics… More >

    Structural Durability & Health Monitoring, Vol.12, No.1, pp. 51-63, 2018, DOI:10.3970/sdhm.2018.012.051

    Abstract Diffusion behavior of chloride ion in reinforced concrete under bending moment was studied by taking the ratio of bending moment to ultimate flexural capacity as load level indicator. The function relationship between load level and chloride ion diffusion coefficient was established, based on that the limit state equation of the chloride ion critical concentration and chloride ion concentration on surface of the steel bar was established. Then by applying Monte-Carlo method the corrosion probability of reinforcement under different load levels in splash zone was calculated. Calculation results demonstrated that compared with the durability reliability index More >
