Background. Reports of retained colorectal foreign bodies (CFBs) are no longer considered uncommon. We present a case where a retained CFB was retrieved using a modified TAMIS technique using standard instruments and trocars. Case Report. A 52-year-old man presented with a CFB. We report our technique of extraction with standard laparoscopic instruments without specialized access platforms. Con...

Operational variables of a mineral processing circuit are subjected to different variations. Steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. In thispaper, a dynamic simulator containing some of the major equipment of mineral processing...

The timing system of the proton accelerator of the PEFP requires synchronization between the accelerator and the multipurpose beam lines. The system is based on an event distribution system that broadcasts the timing information globally to all the equipment. Fast I/O hardware of the timing system is to distribute appropriate timing signals to accelerator systems, including the Injector, RFQ, D...

a few years after the implementation of computerize maintenance management systems (cmms), showing the analysis results of the collected data in these systems is necessary and important for continuing the usage of these systems. equipment downtime and cost data can identify patterns of equipment faults and equipment costs. it can also show deficiencies in the implementation of maintenance syste...

Introduction: Repetitive strain injuries are one of the most prevalent problems in occupational diseases. Repetition, vibration and bad postures of the extremities are physical risk factors related to work that can cause chronic musculoskeletal disorders. Repetitive work on a computer with low level contraction requires the posture to be maintained for a long time, which can cause muscle fatigu...

The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...
