Abstract: Hemangioma of the thyroid gland is a rare diagnosis and less than 35 cases have been previously published in literature. The pathogenesis unknown but it suggested to be developmental anomaly which associated with an incapability angioblastic mesenchyma form canals. On microscopic examination, should distinguished from reactive endothelial hyperplasia, angiosarcoma or hemangiosarcoma. ...

Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...

The variability in travel times is a very important feature in determining the arrival of the passenger at the destination within a given travel time threshold and can be noted as one of the most important characteristic for travel time reliability that is an increasing concern of travelers, because it allows travelers to make better use of their own time. In this paper reliability in multimoda...

increasing water distribution uniformity in micro irrigation systems has been an important subject in applied researches. despite considerable progress in emitters’ construction, some research reports refer to their incapability in water distribution uniformity. in order to achieve greater uniformity in micro irrigation, it is necessary to manufacture emitters with low variation in manufacturin...
