Introduction: Series studies have shown that complications vary based on the kind of IUD, and the smaller the size of IUD is the less the complications, such as bleeding and pain, will be. The aim of this study was to determine and to compare complications including bleeding, pain and etc in CU-T 380 A and CU Safe 300 IUDs users, three months after insertion. Materials and Methods: The presen...

BACKGROUND The IUCD, primarily in the form of copper IUD is used by more than 150 million women around the world, making it the most widely used reversible method of contraception. The objective of this study is to do double blind clinical trial to compare the side effects of Copper-T and Cu 375 IUCD in women using contraceptive method and had used no contraception before. METHOD A total of 8...

We observe that ultrathin Fe/Cu(3)Au(001) films in the 6-13 A thickness range, beyond the thickness of pseudomorphism breakdown at room temperature, exhibit a temperature dependent structural phase transition in the range T(c) approximately 345-380 K. In the high temperature state the Fe film becomes pseudomorphic, while breakdown of pseudomorphism reversibly occurs as the system is cooled belo...

In the present work, in-situ metal matrix composites were fabricated through squeeze casting. The copper particles were dispersed with different weight percentages (3%, 6%, 10%, and 15%) into Al-12% Si piston alloy. Also, heat treatments were performed at 380 °C and 450 °C for holding times of 6 and 18 h. The microstructures, X-ray diffractometer (XRD) pattern, hardness, and wear characteristic...
