Creep-cyclic plasticity and creep-fatigue damage interaction of a welded flange are studied considering both the thermo-mechanical load welding residual stress (WRS). The presence WRS was found to have minimal effect on shakedown ratcheting curves, though distribution changes considerably in WRS. is predominant for initial cycles after which it relaxes so that at steady state creep-cyclic respo...

Woven fabrics prove to be a very convenient fibre reinforcement when prepreg layers have to be draped on to double curvature moulds. The process of draping causes the angle between the warp and weft yarns to vary over the product with this double curvature. As a result, the thermomechanical properties of the fibre reinforced composite material show a corresponding distribution. These thermo-ela...

In order to achieve active confinement in concrete elements, researchers have recently employed smart materials called shape memory alloys (SMA). Several empirical relationships been widely used predict the behavior of confined concrete. To develop more accurate relations for predicting actively with SMA spirals, it is necessary obtain new determining peak compressive stress and corresponding s...

Integrated positron emission tomography combined with plain computed tomography is commonly employed as the diagnostic tool for patients presenting with lung opacities. This technology is non-invasive and does not put the patient at risk of contrast reaction. We report a case of a man who presented with fever, septicaemia, and a left apical lung opacity on chest radiography. His positron emissi...

Sensor technologies have been actively employed in structural health monitoring (SHM) to evaluate structural safety. To provide stable and real-time monitoring, a practical wireless sensor network system (WSNS) based on vibrating wire strain gauges (VWSGs) is proposed and applied to a building under construction. In this WSNS, the data measured from each VWSG are transmitted to the sensor node ...

Gene expression patterning is crucial for environmental nutritional responses such as the nitrogen response in Escherichia coli. The nitrogen response is primarily regulated by the expression of glutamine synthetase (GS), which catalyzes the sole reaction of glutamine formation, by cis-logic regulatory circuits. Here, by removing the entire corresponding operator and promoter regions required f...

mapping based on total concentrations of micronutrients may be useful in fertility management including fertilizer and/or wastewater application. the aims of this work were to (1) investigate the spatial distribution of total concentrations of copper (cu), zinc (zn), manganese (mn) and iron (fe); (2) to select the suitable spatial estimator; and (3) to understand the effect of wastewater irriga...

the revival of chalcolithic sites have a particular importance in tracing the settlement patterns of the region, in the aegis of special biological features and replacing in environmental elements. by depicting the special features, the characteristics of plain of hamedan and its strength in northern plain (kaboodarhang) must be hinted. this plain is determined as a joint fund between central z...

Since columns are the most important elements of the structures, failure of one column in a critical location can cause a progressive collapse. In this respect, the repair and strengthening of columns is a very important subject to reduce the building failure and to keep the columns capacity. Twenty columns with different parameters is tested and analysis. Eleven typical confined reinforced con...
