this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

The molecular and cellular mechanisms that regulate ageing are currently under scrutiny because ageing is linked to many human diseases. The nutrient sensing TOR pathway is emerging as a key regulator of ageing. TOR signaling is complex affecting several crucial cellular functions and two such functions, which show clear effects on ageing, are protein synthesis and autophagy. In this article we...

Aging societies worldwide propose a significant challenge to the model and organisation of the delivery of healthcare services. In developing countries, communicable and non-communicable diseases are affecting how the ageing population access healthcare; this could be due to varying reasons such as geographical barriers, limited financial support and poor literacy. New information and communica...

Fractures associated with osteoporosis are a significant public health risk, and one that is likely to increase with an ageing population. However, many osteoporotic vertebral fractures present on images do not come to clinical attention or lead to preventative treatment. Furthermore, vertebral fracture assessment (VFA) typically depends on subjective judgement by a radiologist. The potential u...

Due to highly constrained ageing infrastructure, current electricity networks will not be able to handle an increased amount of generation; particularly that from intermittent renewable resources deployed within distribution networks. In order to efficiently control this increased generation, decentralised autonomous control is the only viable solution; due to the computational complexities tha...

At least two types of ageing processes affect digital records: media ageing and semantic ageing. We argue that the main challenges for digital preservation arise from semantic ageing, that is, the evolution of data formats. The article analyzes a type of document that is particularly vulnerable to semantic ageing: the digital maps produced by researchers on built heritage which combine spatial ...

As the population of world is increasing, and even more concentrated in urban areas, ensuring public safety is becoming a taunting job for security personnel and crowd managers. Mass events like sports, festivals, concerts, political gatherings attract thousand of people in a constrained environment, therefore adequate safety measures should be adopted. The ageing of the population further incr...

Osteoporotic fractures are associated with significant morbidity, mortality and public health costs, and will increase with an ageing population. Many osteoporotic vertebral fractures (VF) present on images do not come to clinical attention or lead to fracture prevention treatment. Furthermore, DXA vertebral fracture assessments (VFA) are often reported subjectively by a radiologist or other cl...

This paper analyzes the adjustment of consumption expenditures if the subjective mortality hazard increases after a shock. The life-cycle model with mortality risk implies an upward adjustment of consumption expenditures as a response to such a shock. I use data from the Survey of Health, Ageing and Retirement in Europe (SHARE) to test this implication. In each survey wave, the mortality hazard...

This study explored the effect of contrastive phrase resynthesis instruction ongaining the teachability hypothesis stages in self-paced versus time-constrained oralproduction and recognition. Three groups (i.e., 23 learners) of high beginner femalelearners in an English language institute were randomly selected from a cohort oflearners. One group received contrastive metalinguistic instruction ...
