This paper assesses the impact of climate change on novel repair Ferrycarrig Bridge, a reinforced concrete (RC) marine bridge Ireland’s south-east coast. Five unique solutions were applied to seven crosshead beams Bridge during works in 2007. The two under examination herein involved replacement around sides with either 100% Ordinary Portland Cement (OPC) or which 60% cement was made up Ground ...

The coupling effect of bending load and salt spray erosion during the service a sea-crossing bridge accelerates deterioration durability concrete dramatically reduces load-carrying capacity bridge. effects nanoparticles on marine exposed to loads were studied. In this paper, nano-SiO2 nano-Fe2O3 mixed into plain concrete. Free chloride ions (Cl−) titrated at different depths using four-point lo...

Oscillators are kernel components of electrical and electronic circuits. Discussion of history, mechanisms and design based on Barkhausens observation. Discussion of a Wien Bridge oscillator based on the question: Why does this circuit oscillate ?

this paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. we define various factors which are affecting the inventory cost by using the shortage costs. an intention of this paper is to study the inventory modelling through fuzzy environment. inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...

Monitoring, assessing, and understanding the structural health of large infrastructures, such as buildings, bridges, dams, tunnels, and highways, is important for urban development and management, as the gradual deterioration of such structures may result in catastrophic structural failure leading to high personal and economic losses. With a higher spatial resolution and a shorter revisit perio...

This study investigates the deterioration process and mechanism of reinforced concrete (RC) slabs in road bridges under dry stagnant water (wet) conditions. Previous studies used a simple-plate model (SPM) to predict fatigue life RC decks by considering conservative assumptions for safer assessment different environmental processes. To obtain more detailed analysis clarify result mechanism, ful...

Two studies examined the associations between life regrets and indicators of quality of life across the adult life span. Given that opportunities to undo regrets decline with age, regret intensity was expected to be inversely associated with subjective well-being and health among older adults. In addition, the research explored protective factors that have the potential to reduce older adults' ...

Abstract In this paper the relationship between the use of abortion and contraception among married women in a society experiencing uronid decline in fertility is analysed using data from the Korean National Fertility Survey of 1974. The level and pattern of abortion before and after modern contraceptives became widely available are described, and the implications of the changing patterns of ...
