—Mobile Ad Hoc networks (MANETs) are susceptible to having their effective operation compromised by a variety of security attacks. For example, misbehaving nodes can cause general network disruption by not forwarding packets on behalf of other nodes in the network. Nodes may misbehave either because they are malicious and deliberately wish to disrupt the(More)
We have studied the effects of the vasoactive agents phorbol 12-myristate 13-acetate (PMA) and vasopressin (VP) on phosphatidylcholine metabolism in cultured rat glomerular mesangial cells. PMA and VP stimulate the incorporation of [3H]choline into phosphatidylcholine and the release of [3H]choline into the culture medium. VP, but not PMA, also increases(More)
A macroscopic study of the so-called temporomandibular joint of omnivorous mammals (pigs), carnivores (dogs and cats), rodents (rabbits and rats), and herbivores (cows, sheep, and goats) revealed the existence of two left and right temporomandibular articular complexes, each made up of a condylomeniscal and a meniscotemporal joint on either side, as in(More)
We have previously shown that arginine vasopressin (AVP) causes a rapid (5-10 min) contractile response in cultured mesangial cells plated onto slippery substrata such as poly(hydroxyethyl methacrylate)-coated dishes. This contraction is associated with an increase in the levels of inositol trisphosphate (InsP3), diacylglycerol and prostaglandin E2 (PGE2).(More)
The effects of two herbicides used wide-spread, isoproturon (phenylurea) and terbutryn (triazine), on growth, dry weight, elemental composition, photosynthetic pigments and protein content, and cell volume assayed by flow cytometry in the freshwater microalgae Chlorella vulgaris were studied. Different parameters for algal activity show widely different(More)
Mobile Ad Hoc networks (MANETs) are susceptible to having their effective operation compromised by a variety of security attacks. Nodes may misbehave either because they are malicious and deliberately wish to disrupt the network, or because they are selfish and wish to conserve their own limited resources such as power, or for other reasons. In this paper,(More)
Agents known to elevate intracellular cyclic AMP (cAMP) in cultured mesangial cells (e.g., isoproterenol with and without isobutylmethylxanthine (MIX] inhibit vasopressin-induced contraction. Since contraction of these cells in response to vasopressin is accompanied by release of inositol trisphosphate and increased intracellular ionized calcium, we wanted(More)
Wireless ad hoc networks provide the communications platform for new technologies and applications, such as vehicular ad hoc networks or wireless mesh networks. However, their multihop wireless nature makes them inherently unreliable and vulnerable, since their overall performance depends on the cooperative packet forwarding behavior of each individual(More)
Devices in a mobile ad hoc network (MANET) may misbehave by dropping packets that are forwarded in the network, for example because they are malicious and deliberately intend to disrupt the network or because they are selfish and wish to conserve their own limited resources such as power. In this paper, we present a mechanism that enables the detection of(More)
