Abstract This chapter provides an overview of the common types defects found in various structural materials and joints aircraft. Materials manufacturing methods (including large-scale production) have been established aircraft industry. However, as will be seen this chapter, during in-service conditions are very across all material types. The include metals, composites, coatings, adhesively bo...

background: the luteal phase defect is a common event following the ovarian stimulation. the aim of the present study was to evaluate the use of human chorionic gonadotropine (hcg) and progesterone hormones to improve the luteal phase defect. materials and methods: 60 mice were superovulated routinely with human menopausal gonadotropin (hmg) (7.5u) and hcg (10u). the mice were mated and divided...

introduction congenital microgastria is an extremely rare anomaly, which is due to failure of gastric development, and causes a tubular stomach with reduced capacity. it is almost always associated with other congenital anomalies. case presentation the patient was a two-month-old boy with microgastria in association with gastroesophageal reflux, tracheomalacia, and limb defect. discussion most ...

lutembacher syndrome refers to the rare combination of a congenital atrial septal defect and acquired mitral stenosis. traditionally, lutembacher syndrome has been corrected by surgical treatment. we describe two patients treated percutaneouly with a combined inoue balloon valvuloplasty and septal defect closure using the amplatzer septal occlusion device.
