in this research, we investigate the influence of profit management on the long-term performance of ipos in tehran stock exchange. the ipos in 1378 to 1384 are used as our sample and their long-term return in a three-year period after the ipo are calculated. we start calculating the return from the first day after the month in which the financial statement of ipo is published. discretionary cur...
Document summarizes a procedure to establish pay factors for asphalt concrete pavement construction using performance models for fatigue and rutting based on the analysis of accelerated pavement tests from the Caltrans Heavy Vehicle Simulator (HVS) and the WesTrack accelerated pavement performance test program. Results of the performance-based approach are compared with pay factors determined b...
Researchers performed a before-and-after analysis of speeds to determine the short-term and long-term effectiveness of an experimental transverse-bar pavement marking treatment at the “Plainfield Curve” on I-43/94 in Milwaukee, Wisconsin. The experimental transverse pavement marking treatment was installed in both the northbound and southbound lanes in early September 2006 and each treatment se...
Permeable pavement (PP) is used worldwide to mitigate surface runoff in urban areas. Various studies have examined the factors governing the hydrologic performance of PP. However, relatively little is known about the relative importance of these governing factors and the long-term hydrologic performance of PP. This study applied numerical models—calibrated and validated using existing experimen...
Pavement condition evaluation is a significant part of a good pavement management system for effective maintenance, rehabilitation, and reconstruction decision-making. One of the key components of pavement condition evaluation is the quantification of pavement distresses data. Cracking is the main form of early pavement distresses. Cracking of pavement affects road condition, driving comfort, t...
bioaccumulation and depuration of copper in the kidney and liver of a freshwater fish, capoeta fusca
background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...
objective: successful bonding of a dental implant to bone, which was referred to as osseointegration by branemark has been well documented. however, long-term prognosis of an implant depends on adequate maintenance and long-term care. an effective maintenance program is required to preserve the health of peri-implant tissues. several techniques have been suggested for this purpose but it is not...
