The present study examines the relationship between different roles in cyberbullying behaviors (cyberbullies, cybervictims, cyberbullies-victims, and uninvolved) and self-reported digital piracy. In a region of central Spain, 643 (49.3% females, 50.7% males) students (grades 7-10) completed a number of self-reported measures, including cyberbullying victimization and perpetration, self-reported...
today the term globalization is associated with concepts such as unity of economies and societies, the merging of civilizations, of manufacturing and trading companies with banks, change of customs’ policies, increase of trading relations, development of cultural and diplomatic relations, worries of developing countries. globalization is in the best interests of a country if that country has fu...
Consumer grade digital cameras are widely used for close range photogrammetric applications because of the convenience of digital images and the low cost of capture and reproduction. Since the introduction of digital cameras in the 1980s, there has been a strong divide between relatively inexpensive, low resolution, compact digital cameras, and relatively expensive, high resolution, professiona...
a survey on the abundance and diversity of fish larvae along the iranian waters of the oman sea, extending from hormuz strait to gowatr bay, was carried out in 2009 (before and post monsoon). fish larva were collected by a bongo net (300 µ mesh size) and temperature, salinity, dissolved oxygen, ph, chlorophyll-a, clarity, nitrate, nitrite, silicate and sulfate by oceanic data recorder (ctd) and...
there are various methods and models for land evaluation. these methods are classified according to the number of used resources. the best resources capabilities or potentials and land use can be found by analyzing one of the main resources, in the lands close relations to ecologic resources exist. soil has a great potential for introducing the studied region specifications. hence, it challenge...
Iran National Digital Library of Medicine was launched in 2008 by Shahid Beheshti University of Medical Sciences in order to supply English language scientific resources for the Universities of Medical Sciences throughout the country. The Library could be accessed via www.inlm.org. Given the academic definition for national and digital libraries, it seems that the services and resources offered...
Background and Aims: Accurate diagnosis of vertical root fracture (VRF) is a fundamental importance in endodontics. Because of poor prognosis of VRF, digital radiographs with two horizontal angles have limitations in VRF detection. Also, Gutta-percha can produce artifacts that impair CBCT scan accuracy. The aim of this study was to compare accuracy of CBCT and digital radiography system in vert...
In this paper, a new approach using gradient optimization algorithm for delay locked loop (DLL) is provided. Among the salient features of this structure, the proposed DLL can be quickly locked and can be used as a high-frequency circuit. In this novel architecture a digital signal processor (DSP) is used instead of phase detector, charge pump and loop filter. In digital transmitters to select ...
metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...
In the architectural design, designers are focused on the early stages of the design process or conceptual design. The ultimate goal of this stage is to find a solution for an existing problem, investigate design space, or explore an idea. This stage conventionally begins with sketches and diagrams to explore ideas and solutions; the ambiguity and vagueness of conventional freehand sketching ca...
