In certain sections of the state of Indiana sources of recognized ag­ gregates for use in bituminous construction are very few, and the trans­ portation of aggregates to the job site from remote locations becomes necessary. Often the distance over which the aggregate must be moved is considerable, and the importation involves the expenditure of a size­ able sum of money, which it would be desir...

The CHORUS experiment was designed to search for νμ → ντ oscillation by detecting the decay topology of the τ in charged current (CC) ντ events. The detector was exposed to the Wide Band Neutrino Beam of the CERN SPS during the years 1994-1997. About 106νμ CC events were collected in the nuclear emulsion target. Up to now, about 170,000 νμ events have been located and analysed. The speed of the...

One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator surface, which may result in total flashover. The LC characteristics are affected by parameters such as nature and severity of pollution. Loca...

the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

For several years, the bituminous laboratory of the Joint High­ way Research Project has been concerned with the testing of bitu­ minous-aggregate mixtures and with the development of knowledge that would lead to an understanding of the properties of bituminous mixtures as satisfactory paving materials. At the Thirty-Eighth Annual Road School, a paper entitled, “Role of the Laboratory in the De...
