The adaptive significance of avian eggshell architecture
'University of Sheffield Conference Proceedings', 2019Co-Authors: Jackson DuncanAbstract:The avian eggshell plays a critical role in reproduction, providing the primary defence for the developing embryo against the outside world. The aim of this thesis is to understand how and why eggshell microstructure varies. I focus on one particular species, the common guillemot, which incubates its egg in a harsh environment – an exposed dirty, wet rock ledge – without a nest. I also make comparisons with other members of its family, the Alcids. Across Alcids, eggshell thickness increases with adult (parental) body mass. I find eggshells are thicker at the equator in Alcid species that lay more elongate eggs and those that incubate their egg(s) on rock. A putative consequence of enhanced shell thickness at the equator (and potentially pointed end) is that fewer pores are able to form there, and as a result, the thinner blunt end may require a higher pore density to satisfy gas exchange demands. In common guillemot eggs pore density is indeed negatively related to shell thickness. I find that total pore number relates to egg size – but not incubation period – across the Alcids. As eggshell pores are open channels from the outside into the egg, they pose a risk if they allow foreign matter to enter the eggshell. I show that shell Accessory Materials on common guillemot eggs provide protection, preventing foreign Material from entering and blocking pores. I suggest that eggshells with a rough surface, particularly at the equator, may be better able to keep shell Accessory Material adhered to the shell, minimising the impact of abrasion from hard rock substrates. Intriguingly, I also show that surface microstructure relates to eggshell colour and pattern. Overall, these findings provide a detailed insight into how eggshell structure varies within and between individuals and species, with important implications for our understanding of avian eggshell function

The effects of interior design made with digital visualization tools and applications on users perceptional performance
Nilay ÖZSAVAŞ ULUÇAY, 2021Co-Authors: Ömer Koyuncu, Mehmet Lütfi Hidayetoğlu, Bahattin Ali Türkmenoğulları, Kemal YıldırımAbstract:This study focuses on designs produced by using digital visualization tools and the effects of this applications on the perceptional performance of users. The aim of this study is to determine the differences between the space visuals produced by using digital techniques and the new appearances emerged after their applications, after the applications and also to designate the reasons of these differences. For this purpose, ten different locations which are designed and produced by interior architecture offices operating in Konya were selected. The experiment was carried out with 148 university students and ensured this subjects to evaluate the perceptual differences between digital and real spaces. As a result of the research, it has been found that the most frequently used effects (wide angle, light intensity and lighting) and design preferences (reinforcement / Accessory, Material / surface coating and color) are mostly prefered to show the spaces more effectively when producing space images with digital techniques. It is determined that the spaces where visualizations are made cannot have the same perceptual effect after they are actually applied. However, it was seen that individuals taking undergraduate education evaluated the real and digital spaces more negatively than the individuals who received an associate degree education and the individuals evaluated the spaces more critically as the training period increased. In addition, it is determined that women evaluate places more negatively than men

student brain strengthening health care product
2015Co-Authors: Wang ShizhunAbstract:The present invention discloses a student brain strengthening health-care product which includes salmon, eggs, garlic, walnuts, pineapples, blackberries, carrots, sunflower seeds and Accessory Materials. Every 100 grams of the brain strengthening health-care product contains the components as follows: 2%-4% salmon, 6%-10% eggs, 1%-3% garlic, 2%-6% walnuts, 6%-10% pineapples, 5%-8% blackberries, 3%-8% carrots, 4%-10% sunflower seeds and 45%-60% Accessory Materials; and the Accessory Material consists of beans and oats. The student brain strengthening health-care product is made into powder and packaged, and is suitable for the consumption of students at 6-18 years old. The beneficial effects of the health-care product are that the health-care product can improve the supply of nutrients in the brain and promote glucose transfer into brain energy, and can strengthen body and brain, improve learning and memory ability, maintain the health and vitality of brains, and is suitable for brain needing student stage.
