Indoor corrosion failures of aluminum-finned copper-tube evaporator coils, and also in some systems without aluminum fins, is a menacing issue in the heating, ventilation, and air conditioning (HVAC) industry. Extensive laboratory testing has verified the development of a reproducible screening method to assess suspected contaminants of producing premature failures of copper tube resulting from...

India is one of the largest automotive industries in the world and one of the fastest growing globally. Now all automakers are concentrating on India for the promising growth in the sector. So competition in this industry is very high. Hence, there is a need to focus more on product development. The development of the product needs to be started from conceptual design with low cost, high perfor...

Higher-powered electronics are being integrated into automobiles rapidly. With these electronics comes a problem of how to cool this equipment economically. Heatsink costs have not benefited nor adapted to the high volume nature of automotive electronics. Specially shaped heatsinks are much more efficient for a given size than aluminum extrusion-based ones, most prevalent used in automobiles. H...

Climate policy regarding perfluorocarbons (PFCs) may have a significant influence on investment decisions in the production of primary aluminum. This work demonstrates an integrated analysis of the effectiveness and likely economic consequences of different climate policy options. In our study we first compare atmospheric observations to the available estimates of PFC emissions for the baseline...

INTRODUCTION Patients with hand disorders frequently experience difficulties opening peelable packaging. PURPOSE To investigate the forces patients can apply to tear tabs and to compare the results with normative data to make recommendations for the industry and clinical practice. STUDY DESIGN Descriptive, cross-sectional. METHODS One hundred patients with hand disorders were studied. The...

Laser cutting has been investigated for a number of aluminum±synthetic laminates, newly developed materials for the aeronautic and automotive industry. The materials consist of alternating aluminum and synthetic layers. It is shown that these materials can be cut at the same speed as homogeneous aluminum alloys, although some damage on the synthetic layers has to be accepted. Based on these exp...

You are to be congratulated on publishing the very thought-provoking article by P. 0. Ganrot, entitled "Metabolism and Possible Health Effects of Aluminum" (1). After reviewing a substantial part of the extensive literature, Ganrot analyzes it carefully and shows that an element of the properties of aluminum will indeed prejudice normal function if it reaches sensitive parts of the organism. Hi...

This work reports on the viability of the electroflocculation (EF) process for chemical oxygen demand (COD), turbidity and color removal from a raw effluent originated from a particular textile industry related to hemp manufacture. Firstly, the following operational parameters were optimized: current density; initial pH; electrolysis time; material of the electrode (iron, aluminum or iron-alumi...

Recycling aluminum alloys has been shown to provide major economic benefits, as a result it is appropriate for the aluminum industry and the United States as a whole to identify, develop, and implement all technologies that will optimize the benefits of recycling. This paper will focus primarily alloy design for optimizing the reuse of recycled metal; this is both the most forward looking as we...
