Effect of Cd Additive on the Hardness and Tensile Properties of Al-Mg-Si Alloy

The aim of this paper is to study the effect of adding Cd element to aluminum alloy series (6000) on the mechanical properties (hardness & ultimate tensile strength ) which have been studied  .A permanent  mold casting method was used for preparing the specimens of alloys by adding Cd at (0.1,0.3,0.5)% wt . to (Al-Mg-Si ) alloy. Heat treatment homogenous alloy ingots were carried out at (550ºC) for (24 hours) .These heat treatments for all specimens were conducted after cutting the ingots to the required dimensions ,solution heat treatment at (500ºC) for (1 hour) and then quenching in the water at room temperature. Then natural aging was carried out at room temperature for (90 days) ,whilst with in this period the hardness of alloys were measured at subsequent equal interval . The artificial aging for the prepared alloys was carried out, at (160and 180) ºC for an interval ranging between (5 mins. & 35 hours) .The Vickers  hardness and ultimate tensile strength were measured .The hardness and ultimate tensile strength of Cd alloys have relative improvements  by natural aging. Keywords: Cd element, (Al-Mg-Si ) alloy, homogenous, artificial& natural aging

An electronic infrastructure for research and treatment of the thalassemias and other hemoglobinopathies: The Euro-Mediterranean ITHANET project

Hemoglobin (Hb) disorders are common, potentially lethal monogenic diseases, posing a global health challenge. With worldwide migration and intermixing of carriers, demanding flexible health planning and patient care, hemoglobinopathies may serve as a paradigm for the use of electronic infrastructure tools in the collection of data, the dissemination of knowledge, the harmonization of treatment, and the coordination of research and preventive programs. ITHANET, a network covering thalassemias and other hemoglobinopathies, comprises 26 organizations from 16 countries, including non-European countries of origin for these diseases (Egypt, Israel, Lebanon, Tunisia and Turkey). Using electronic infrastructure tools, ITHANET aims to strengthen cross-border communication and data transfer, cooperative research and treatment of thalassemia, and to improve support and information of those affected by hemoglobinopathies. Moreover, the consortium has established the ITHANET Portal, a novel web-based instrument for the dissemination of information on hemoglobinopathies to researchers, clinicians and patients. The ITHANET Portal is a growing public resource, providing forums for discussion and research coordination, and giving access to courses and databases organized by ITHANET partners. Already a popular repository for diagnostic protocols and news related to hemoglobinopathies, the ITHANET Portal also provides a searchable, extendable database of thalassemia mutations and associated background information. The experience of ITHANET is exemplary for a consortium bringing together disparate organizations from heterogeneous partner countries to face a common health challenge. The ITHANET Portal as a web-based tool born out of this experience amends some of the problems encountered and facilitates education and international exchange of data and expertise for hemoglobinopathies.
