“…The combination of thyme EO (at 0.4, 0.8 and 1.2%) and nisin (at 500 or 1000 IU/g) decreases Listeria monocytogenes population below the acceptable level (2 log cfu/g) and displayed strong antibacterial activity than the individual usage of EO or nisin in minced fish meat during storage period (4°C for 12 days) [41]. Samy Selim [42] studied the effect of eucalyptus, juniper, mint, rosemary, sage, clove and thyme oils on vancomycin-resistant Enterococci (VRE) and E. coli O157:H7 in minced beef meat and observed that sage and thyme oil exhibit strong antimicrobial activity against the tested microorganism.…”

Safe and hygienic food is a requirement for a healthy society. The problem of food-borne outbreaks has built a challenge against the food and health regulatory authorities to control the pathogenic microorganisms. Chemical preservative has created some health problems in foods, so the recent trend is towards the use of natural antimicrobials in foods. Plants are valuable source of bioactive molecules exhibiting antimicrobial activities. The plant antimicrobial compounds have diverse chemical nature such as alkaloids, phenolics, terpenes, terpenoids, flavonoids, essential oil, etc. Many plant antimicrobials possess antimicrobial activity against pathogens and spoilage microorganisms. But variation in effectiveness of these compounds against microorganisms in laboratory system and in real food systems is major determinant in their food use. Several plant extract or purified compounds are part of human diet since thousands of years. Although some plant compounds enjoy the status of generally recognised as safe (GRAS), typical toxicological information of their use in food is not available. So the improvement in cost-effective isolation and toxicological information of these compounds is helpful in their use as biopreservative in foods.

“…As for time-independent problems, the widely used GRS algorithms are the variance-based method 27 and the moment independent-based method. 28 It is worth noting that not only the reliability, but also any response, including maximum stress and displacement, robustness, 29,30 etc., can be considered as the target of sensitivity analysis. Based on the variance-based method, Wei et al 31 deduced the TD-LRS index and TD-GRS index according to the envelop function method, and successfully applied the proposed method to screen out the important input variables for a four-bar mechanism and a rack and pinion steering linkage mechanism, respectively.…”

The sensitivity index plays a critical role in the design of product and is used to quantify the impact degree of the uncertainty of the input variable to the uncertainty of the interest output. This paper presents a new local reliability sensitivity method and a global reliability sensitivity analysis method of time-dependent reliability problems. Firstly, according to the Poisson's assumption-based first-passage method, the local reliability sensitivity index is directly obtained by calculating the partial derivative of the failure probability to the distribution parameters of input random variable. Then, the moment-independent global reliability sensitivity index of the time-dependent problems is derived based on the concept of moment-independent. Finally, the efficiency and accuracy of the proposed method are verified with the reference results of Monte Carlo simulation.

“…Fewer studies deal with the interaction between earthquake and blast load. Abdollahzadeh and Faghihmaleki [18] evaluated the robustness of a seismic designed RC structure under blast load with deterministic, probabilistic and risk-based methods but did not investigated the influence of seismic demand. The latter risk-based approach has been developed in [19] considering a multi-hazard analysis for seismic and blast critical events.…”

Fragility Curves for RC Structure under Blast Load Considering the Influence of Seismic Demand

The complex characteristics of explosion load as well as its increasingly high frequency in the civil environment highlight the need to develop models representing the behavior of structures under blast load. This work presents a probabilistic study of the performance of framed reinforced concrete buildings designed according to the current Italian NTC18 and European EC8 technical standards. First, a simplified single degree of freedom model representing the structural system under blast load has been developed. Then, a probabilistic approach based on Monte Carlo simulation analysis highlighted the influence of seismic demand on the behavior of Reinforced Concrete RC buildings subjected to blast load.
