in recent years mobile networks have expanded dramatically, compared with other wireless networks. routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. in this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

In my research I am developing new multiliteracy models for computer interface design. These design models are derived from dynamic, time-based communication structures used in oral communication in Indigenous cultures. The research uses visual patterns to represent the changing semantic structures in an interactive information space where there are numerous networks of associations. These mult...

abstract background: the aim of this study was to compare the effects of the second- and third-generation oral contraceptives on women’s reproductive sexual function. materials and methods: this randomized, double-blind, placebo-controlled clinical trial was conducted on 82 married women of reproductive age in tehran. samples were randomized into the groups receiving second- and third-generatio...

BACKGROUND Since its foundation in 1920, prevention of oral disease has been a priority for the International Association for Dental Research (IADR) and the commitment of the organisation to the subject area is clearly expressed in its mission to improve oral health worldwide. The IADR has a current global membership of almost 11,000 people who share an interest in oral and craniofacial researc...

in the present study, sodium alginate microparticle for oral delivery of furosemide was designed whether the encapsulation into microparticles might improve the oral absorption of this potent loop diuretic. we described preparation of microspheres based on ionotropic gelation method and characterized its physicochemical properties. to acquire an optimum formulation, a generalized regression neu...

BACKGROUND The aim of the study was to quantify the scientific productivity of researchers, organizations, and regions in Spain that publish articles on implantology in dental journals indexed in Journal Citation Reports. MATERIAL AND METHODS A search was conducted among the core collection of Thomson Reuters' Web of Science database, on the basis of its broad thematic and geographic coverage...

The characterization of brain networks contributing to the processing of oral and/or intestinal sugar signals in a relevant animal model might help to understand the neural mechanisms related to the control of food intake in humans and suggest potential causes for impaired eating behaviors. This study aimed at comparing the brain responses triggered by oral and/or intestinal sucrose sensing in ...

BACKGROUND Rural residents have poorer oral health and more limited access to dental services than their city counterparts. In rural communities, health care professionals often work in an extended capacity due to the needs of the community and health workforce shortages in these areas. Improved links and greater collaboration between resident rural primary care and dental practitioners could h...
