DOI: 10.1007/s11205-016-1500-5
Abstract: One of the most controversial steps in Composite Indicators (CIs) construction is the selection of one (possibly) best weighting technique. In this paper, we introduce a new endogenous weighting methodology developed in an extended Item… read more here.

DOI: 10.1007/s11356-021-17789-5
Abstract: The relationship between perfluoroalkyl and polyfluoroalkyl substances (PFAS) and cognitive function are inconsistent, and the mixed effects of PFAS on cognitive function are still unclear. We aimed to evaluate the joint effects of PFAS on… read more here.

DOI: 10.1016/j.conbuildmat.2017.05.175
Abstract: Abstract Infrared thermography (IRT) has been used experimentally for concrete delamination detection. The past studies were conducted with limited experimental conditions, which make a difference in delamination detection. As a result, there are inconsistencies in… read more here.

DOI: 10.1016/j.enbuild.2018.07.052
Abstract: Abstract Thermal radiation generated by limited resources is emitted from the surfaces and interpreted as temperature. On the other hand, the limited resources necessitate prevention of energy leakages causing noticeable temperature differences on surfaces. Providing… read more here.

DOI: 10.1016/j.jrmge.2020.05.003
Abstract: Abstract Previous studies show that infrared radiation temperature (IRT) abnormalities are always accompanied by the crack development in rocks under external loads. In this context, experiments were conducted on preflawed sandstone to investigate the infrared… read more here.

DOI: 10.1038/s41440-019-0360-1
Abstract: Exercise guidelines for managing hypertension maintain aerobic exercise as the cornerstone prescription, but emerging evidence of the antihypertensive effects of isometric resistance training (IRT) may necessitate a policy update. We conducted individual patient data (IPD)… read more here.
