\u27It\u27s Just What You Do:\u27 Exploring Relationships Between Young-Adult Grandchildren and their Grandfathers

The grandparent role is a dynamic and often ambivalent relationship requiring simultaneous navigation of “being there” and “not interfering” in the lives of grandchildren (Mason, May, & Clarke, 2007). These relationships change as grandchildren mature and can result in new grandparent-grandchild connections based on communication, intimacy, and mutual respect (Sheehan & Petrovic, 2008). Utilizing a sample of grandfathers and young-adult grandchildren (N = 32), this study investigated the impact that grandfathers have on their young-adult grandchildren. Utilizing a life course perspective, we asked: a) How do grandfathers invest in the futures of their young-adult grandchildren? b) How do young-adult grandchildren recognize and receive their grandfather’s investments in their futures? Results suggest that grandfathers emphasized their grandparenting role but undervalued their contributions to their grandchildren. Grandfathers and grandchildren also did not always agree on the transmissions intended and received. When asked to recall meaningful memories of grandfathers, young-adult grandchildren were more likely to remember instances of shared hobbies, interests, and personal connection. Findings have implications for understanding and strengthening the ties between grandfathers and their grandchildren

High temperature optical absorption investigation into the electronic transitions in sol–gel derived C12A7 thin films

Optical absorption into 6 mm thick sol–gel derived films, annealed at 1300 °C of 12CaO·7Al2O3 calcium aluminate binary compound on MgO〈100〉 single crystal substrates was studied at temperatures ranging from room temperature to 300 °C. Experimental data were analysed in both Tauc and Urbach regions. The optical band gap decreased from 4.088 eV at 25 °C to 4.051 eV at 300 °C, while Urbach energy increased from 0.191 eV at 25 °C to 0.257 eV at 300 °C. The relationship between the optical band gap and the Urbach energy at different temperatures showed an almost linear relationship from which the theoretical values of 4.156 and 0.065 eV were evaluated for the band gap energy and Urbach energy of a 12CaO·7Al2O3 crystal with zero structural disorder at 0 K

Function and failure of the fetal membrane : modelling the mechanics of the chorion and amnion

The fetal membrane surrounds the fetus during pregnancy and is a thin tissue composed of two layers, the chorion and the amnion. While rupture of this membrane normally occurs at term, preterm rupture can result in increased risk of fetal mortality and morbidity, as well as danger of infection in the mother. Although structural changes have been observed in the membrane in such cases, the mechanical behaviour of the human fetal membrane in vivo remains poorly understood and is challenging to investigate experimentally. Therefore, the objective of this study was to develop simplified finite element models to investigate the mechanical behaviour and rupture of the fetal membrane, particularly its constituent layers, under various physiological conditions. It was found that modelling the chorion and amnion as a single layer predicts remarkably different behaviour compared with a more anatomically-accurate bilayer, significantly underestimating stress in the amnion and under-predicting the risk of membrane rupture. Additionally, reductions in chorion-amnion interface lubrication and chorion thickness (reported in cases of preterm rupture) both resulted in increased membrane stress. Interestingly, the inclusion of a weak zone in the fetal membrane that has been observed to develop overlying the cervix would likely cause it to fail at term, during labour. Finally, these findings support the theory that the amnion is the dominant structural component of the fetal membrane and is required to maintain its integrity. The results provide a novel insight into the mechanical effect of structural changes in the chorion and amnion, in cases of both normal and preterm rupture
