2. Introduction
Young's modulus is one of the important materials properties that is related with the bonding force between atoms or ions in materials. That will give a clear explanation why ceramic materials generally have a higher Young's modulus than metallic one. In engineering field, Young's modulus is used for input data that is necessary to analysis the structural change, mechani

1. SPG시스템 이란?
SPG시스템은 프레임이나 구조용 실리콘을 사용하지 않으면서도 탁월한 안전성을 유지하며, 뛰어난 디자인으로 건축물의 자연미를 극대화하고, 개방감과 채광성을 최대한 보장해 준다. SPG시스템은 특수 가공한 볼트를 접시머리 모양으로 가공된 홀에
1. What are anabolic steroids?
(1) Definition and structure of anabolic steroids
Anabolic steroids - or more precisely, anabolic-androgenic steroids are synthetic derivatives of testosterone.
The effects of anabolic-androgenic steroids mimic those of testosterone. Natually synthesized hormones, such as testosterone, are types of lipids. they have a four-ring carbon skeleton and are synthe
