The objective of the work is to present some researches regarding composits. The aim is motivated by the new materials such as composites and structural concepts, sandwich construction that have resulted in lighter structural designs with superior performance. There are presented and discussed the types of matrix materials, sandwich construction, failure modes in sandwich structures and design considerations. It is not possible to cover every aspect of this vast subject. The purpose here is to impart the basic knowledge so that the people involved in the structural repairs will have better understanding of the processes.

Our results were obtained by examining subjects without renal pathology, aged 26-83 on a General Electric - Voluson 730 Expert ultrasound. The left kidney length was found between 56.98-122.90 mm, for female being 56.98-110.60 mm, and for male 84.73-122.90 mm. The length of the right kidney was between 55.50-125.0 mm, for female being 55.50-108.40 mm, and for male 62.04-125.0 mm. The width of the left kidney in the renal hillum was found to be between 15.54-41.10 mm, for female being between 15.54-31.0 mm, and for male between 16.19-41.10 mm. The thickness of the left kidney in the renal hillum was found to be between 40.0-75.80 mm, with the female being 44.02-71.02 mm, and the male between 40.0-75.80 mm. The right kidney thickness in the renal hillum was found to be between 41.67-82.36 mm, for female being between 41.67-60.27 mm and for male 43.89-82.36 mm.
