NDT is mainly discussed as an engineering technology to detect, classify and size material imperfections, called material defects. Lattice defects and microstructure inhomogeneities like vacancies, dissolved atoms dislocations and precipitations are normally not discussed as defects but they are influence parameters which mainly predict the macroscopic properties, the physical properties as wel...
Background and Objective: Aging like many complex traits is the result of interaction between genome and environmental factors and epigenetic mechanisms as a central connector links these two markers. So far, investigations on age-related characteristics and biomarkers predicting survival and risk of death have been carried out, none of which led to an overall consensus among the researchers. I...
We present an effective time approach to predict long and short time rheological behavior of soft glassy materials from experiments carried out over practical time scales. Effective time approach takes advantage of relaxation time dependence on aging time that allows time-aging time superposition even when aging occurs over the experimental time scales. Interestingly, experiments on a variety o...
Nowadays, in addition to materials and components of asphalt mixtures that are bitumen, aggregates and mineral fillers, other materials known as additives or modifiers are also used. These compounds include wide range of organic, inorganic, industrial, and natural materials used in order to reduce deficiencies, to improve the physical properties and to modify some mechanical properties o...
Objectives: The beliefs and perceptions regarding aging have an important effect on the well-being of the elderly population. A self-regulation model is one of the useful theoretical models to explain the role of perceptions and beliefs about aging in determining the health outcomes of elderly people. The aim of this study was to determine the relationship between aging-related perception ...
Objectives This study aimed to analyze the relationship personality traits (neuroticism and extraversion) and self-efficacy with aging depression in retiree male teachers in Harsin City, Iran. Methods & Materials The present study followed a cross-sectional descriptive correlation method. In this research, a total of 173 retiree male teachers in Harsin were selected by random sampl...
Objectives In recent decades, it has become important to approach aging issues from the point of view that can ensure older adults’ Quality of Life (QoL). As a result, countries have adopted a positive perspective with regard to aging, including active aging. The fact is that indigenous understanding of active aging is an unavoidable necessity for every society. Thus, the current study&rs...
food safety is considered as an important world concern. the detection of pathogen and toxic materials in food has an important role in public health care. in recent years, the applications of microbial biosensor have been developed as a new approach for toxicity control. luminescent microbial biosensor is an appropriate biological tool for protection of natural environment. this type of biosen...
