Surface reconstruction: Surface reconstruction refers to the process by which atoms at the surface of a crystal assume a different structure than that of the bulk. Surface reconstructions are important in that they help in the understanding of surface chemistry for various materials, especially in the case where another material is adsorbed onto the surface.Chorion (egg): The chorion is the outermost membrane around the embryo in mammals, birds and reptiles. It develops from an outer fold on the surface of the yolk sac, which lies outside the vitteline envelope and is developed by the follicle cells while the egg is in the ovary.Nordli's Cabinet: Nordli's Cabinet governed Norway between 15 January 1976 and 4 February 1981. The Labour Party cabinet was led by Odvar Nordli.Biocell Center: Biocell Center is an international company specializing in the cryopreservation and private banking of amniotic fluid stem cells. The company is headquartered in Italy with several international locations and is involved with numerous partnerships and research studies of amniotic fluid stem cells,.Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Congenital amputation: Congenital amputation is birth without a limb or limbs, or without a part of a limb or limbs.Decidual reaction: The decidual reaction is the changes in the endometrium of the uterus that prepare it for implantation of an embryo. These changes are observed in each menstrual cycle and enhanced after implantation.Placenta: The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply, fight against internal infection and produce hormones to support pregnancy. The placenta provides oxygen and nutrients to growing babies and removes waste products from the baby's blood.Premature rupture of membranes
