This paper focuses on Deep-Seated Gravitational Slope Deformations (DSGSDs) identified in the Molise region (Italy), along central-southern sector of Apennines chain. These phenomena were detected and mapped through a combination aerial-photo interpretation, morphological analyses, field surveys, integrated satellite SAR interferometry (InSAR). The obtained general map is organized different se...

Background: Photo-damaged skin is characterized not only by wrinkles and creases but also by epidermal and dermal atrophy, rough skin texture, irregular pigmentation, talengiectasis , laxity and enlarged pores. There is growing interest in the development of noninvasive methods to treat photo-damaged skin. Intense Pulsed Light (IPL), a non-coherent, broadband, pulsed light source is effective i...

  Optogalavanic technique has been used widely in laser spectroscopy. In this paper we have presented the results of an experimental three- step photo- excitation of Gd atom, using optogalvanic technique. Three tunable dye laser pulses were applied to excite the Gd atom in a three-step photo – excitation process. The optogalvanic signal was used to monitor the laser wavelength and efficiency of...

The problems of photo aesthetic and photo quality are similar, but not exactly the same. In photo aesthetic assessment, we seek photos that looks beautiful to people. The aesthetic score of a photo can be affected by the photo’s color tone, composition, layout, and etc. In photo quality assessment, we seek photos that are in high quality. The quality score of a photo can be affected by shake, b...

Abstract. Nowadays, there are many methods and techniques for the documentation restoration of historic structures historical artifacts that commonly used due to their completeness, accuracy fastness. The use advanced 3D measurement technologies, by either using terrestrial or aerial means acquiring digital data, has become an efficient reliable tool. Within this context, study focuses on combi...

Entanglement in fishing gear is a significant threat to many cetaceans. For the 2 largest species, blue whale Balaenoptera musculus and fin B. physalus , reports of entangled individuals are rare, leading assumption that entanglements not common. Studies interaction with fisheries other species often rely on presence scars from previous entanglements. Here, scar detection rates were first exami...
