Solutions and Stability of Generalized Mixed Type QC Functional Equations in Random Normed Spaces
We achieve the general solution and the generalized stability result for the following functional equation in random normed spaces (in the sense of Sherstnev) under arbitrary t-norms: , where for any fixed integer with .</p
Wireless mesh network routing: A comparative survey
Nowadays, the wireless network technology, as a very cheap alternative Very cheap to create associative networks and unified are under development. Although such networks are economically very affordable and are also numerous operational efficiency, including dynamic capability and comfort give and offer to the end user. Among the networks-based infrastructure, a wireless mesh network (as a set of wireless router are taken at strategic locations, providing total connectivity to the network) also provides flexibility for multi-hop. Therefore, how can efficiently these packages through the wireless network arrive to the destination, is a very important problem. Unlike routing wired networks, wireless routing faces with challenges such as interference, among other transfers and channel variable characteristics. In a wireless network, the routing algorithms are divided in numerous categories ranging from algorithms Geographic routing, Geo-Casting, hierarchical, multi-path, based on the remaining energy and hybrid (combination). In this article, Check routing algorithms are discussed
The effect of Quercus brantii gall extract on burn wound healing in rat
Objective(s): The aim of the present study was to evaluate the effect of Quercus brantii galls extract on the rat skin burn wound healing. Materials and Methods: Ethanol extract of the galls of Q. brantii was used to treat the induced burn wounds on the back of 32 Wistar rats divided into 4 groups. The groups were treated by placebo, 1%, 2% and 4% concentration gall extract gels for 14 days and the efficacy of treatment was assessed based on reduction of burn wound area, as well as histological and molecular characteristics. Results: The mean wound surface in the 14th day, in all groups treated by Q. brantii gall extracts were larger than control group and the differences were statistically significant (P=0.043). The mean histological wound healing scores were not statistically different. Analysis of nitric oxide and platelet derived growth factor concentration in wound fluids in the 5th day of study showed that there was not any significant difference between groups (P=0.468 and 0.312 respectively). Fibroblast growth factor (bFGF) concentration in the wound fluids, was significantly higher in group treated with 1% gall extract gel in comparison to the control group (P=0.026). Conclusion: Our results could not prove the significant positive effect of Q. brantii galls extract on the burning wound healing. More studies with more groups treated with different doses of the Q. brantii extract are recommended
