background: sediments in marine environment have a large capacity in binding with heavy metals; therefore, they are potential pollutants of water resources. the anzali wetland, located in the southern region of the caspian sea, iran, has been consistently threatened by heavy metal pollutants because of urban, agricultural and industrial wastewater inflow. the purpose of this study is to investi...

METAL transfer describes the process of the molten metal movement from the electrode tip to the workpiece in gas metal arc welding (GMAW). A better understanding of the metal transfer process is important for improvements in the quality and productivity of welding. While several distinct modes of the metal transfer have been classified,[1] the globular and spray transfer modes have received att...

The main challenge for the practical application of metal hydride heat pump (MHHP) is the relatively poor system performance, which is mainly caused by the undesirable heat transfer performance of reaction bed. However, there is no significant improvement of system performance when enhancing the effective thermal conductivity (E.T.C) of reaction bed. In order to identify the relationship betwee...

This is a case report involving a single case with severe bone and soft tissue destruction in a young male patient with a 10-year-metal on-metal total hip arthroplasty. Following complete aseptic erosion of the affected hip greater trochanter and abductor muscles, the hip was revised for recurrent instability. Histological examination of the patient's periprosthetic tissues, serological studies...

corophium volutator (pallas) has been recommended by the paris commission as one of the standard species for testing chemical used in offshore oil and gas exploration/production. in the present study, gut contents of corophium volutator have been analysed by electron probe microanalysis (epma) for baso4 and other heavy metal impurities after exposure tto spiked sediments following a standard as...
