modified bituminous materials can bring real benefits to highway maintenance/construction, in terms of better and longer lasting roads, and savings in total road life castings. this paper present the effect of there novel modifier as precipitated calcium carbonate (pcc) and two type of nanoclay on rheological properties of bitumen binder. various blends of modifier and bitumen were selected and...

The timing of the disappearance of the snow cover in spring, or snow melt day (SMD), is a key parameter controlling the carbon dioxide balance between the northern mire and heath ecosystems and the atmosphere. We present a simple method for the determination of the SMD using a satellite-based surface albedo product (SAL). The method is based on the local change of albedo from higher wintertime ...

A common and high-performance practice when carrying out euclidian reconstruction from two cameras is to rst calibrate both cameras thanks to a pair of images of a calibration object. However, it remains di cult to accurately determine the intrinsic parameters of each camera and we know their value have a signi cant e ect on Euclidian reconstruction. Moreover, the calibration issued from a sing...

PURPOSE To analyze whether rebamipide (REB) and carteolol hydrochloride (CH) protect against UVB-induced corneal damage in mice. METHODS BALB/c mice topically pretreated with REB (1 and 10 mM) or CH (1, 10, and 100 mM) were exposed to ultraviolet (UV) B light at 416 micro W/cm(2). To evaluate corneal damage, mire irregularity was graded, and the haze index was estimated by using digitized cor...
