The challenges of an aging population require the adoption of inhome and medical technologies to complement the traditional caregiver model. Adoption of such technologies is, however, impinged by privacy concerns. This study investigates a four dimensional framework that explains the tradeoffs between functionality and privacy as constructed by older adults. The four dimensions constitute perce...
Sufficient deformability can be achieved in concrete while maintaining segregation resistance either by using a chemical viscosity-modifying admixture (VMA) or increasing the fine content concrete. Using VMA, initial cost of self-compacting (SCC) increases, making it unsuitable for general construction. As result, alternative methods lowering SCC must investigated. In this study, we assess effe...
Autogenous shrinkage may be a critical issue concerning the use of limestone-calcined clay-cement (LC3) in high-performance concrete and 3D printable cementitious materials, which have relatively low water to binder (W/B) ratio. Adding an internal curing agent, i.e., superabsorbent polymer (SAP), could viable solution this context. However, employing SAP (without adding additional water) also i...
Abstract Climate action around the world has shifted to potential of global warming contribution from design and construction infrastructures, especially those in demand for concrete. Concrete production use have been identified as contributing >5% world’s greenhouse gas (GHG) emissions. The main aim this research work is critically study net-zero sustainability potentials that can lever...
Sex-biased demography, in which parameters governing migration and population size differ between females and males, has been studied through comparisons of X chromosomes, which are inherited sex-specifically, and autosomes, which are not. A common form of sex bias in humans is sex-biased admixture, in which at least one of the source populations differs in its proportions of females and males ...
clopidogrel, an inhibitor of platelet aggregation, selectively inhibits the binding of adenosine diphosphate (adp) to its platelet receptor and the subsequent adp-mediated activation of the glycoprotein gpiib/iiia complex, thereby inhibiting platelet aggregation. oral bioavailability of clopidogrel is very low (less than 50%), due to its poor water solubility. the aim of this investigation was ...
Admixture occurs when individuals from parental populations that have been isolated for hundreds of generations form a new hybrid population. Currently, interest in measuring biogeographic ancestry has spread from anthropology to forensic sciences, direct-to-consumers personal genomics, and civil rights issues of minorities, and it is critical for genetic epidemiology studies of admixed populat...
When previously isolated populations meet and mix, the resulting admixed population can benefit from several genetic advantages, including increased genetic variation, the creation of novel genotypes and the masking of deleterious mutations. These admixture benefits are thought to play an important role in biological invasions. In contrast, populations in their native range often remain differe...
