This article presents a comprehensive survey of routing protocols proposed for routing in Vehicular Delay Tolerant Networks (VDTN) in vehicular environment. DTNs are utilized in various operational environments, including those subject to disruption and disconnection and those with high-delay, such as Vehicular Ad-Hoc Networks (VANET). We focus on a special(More)
Argininosuccinate lyase (ASL), the fourth enzyme of the urea cycle, belongs to a group of liver enzymes appearing in the late foetal period in the rat. Several hormones, including glucocorticosteroids and insulin have been implicated in the control of the development of this enzyme activity. In this study, the cloned cDNA was used to measure the relative(More)
Expression of the hepatic enzyme argininosuccinate lyase (ASL), one of the urea cycle enzymes, was analyzed during the perinatal period in the rat. To this end, ASL was purified, an ELISA assay was established to quantify the enzyme protein and a cDNA clone was used to measure the amount of specific mRNA in the liver in various stages of development. During(More)
Vehicular Delay-Tolerant Networks (VDTNs) are composed of mobile nodes (vehicles) that communicate with each other wirelessly and using store carry and forward paradigm to forward data despite intermittent connectivity. A serious threat against routing process in such context is the non-cooperation of nodes. Some of them misbehave because they are(More)
During the perinatal period, the activity of the urea-cycle enzyme argininosuccinate lyase (ASL) is regulated by glucocorticoids, glucagon and insulin. In this study, the effects of glucagon and cyclic AMP (cAMP) analogues were examined on the synthesis of ASL and on the level of its corresponding mRNA in cultured foetal hepatocytes.
