In this paper we introduce a novel routing protocol for efficiently broadcasting packets in vehicular ad hoc networks, while limiting multiple copies of the same packet and avoiding collisions. In high congested traffic scenarios, the increase of packet collisions and medium contentions among vehicles, affects the intervehicular communications and causes a degradation of Quality-of-Service (QoS...

We prove the existence of SRB measures for diffeomorphisms where a positive volume set of initial conditions satisfy an “effective hyperbolicity” condition that guarantees certain recurrence conditions on the iterates of Lebesgue measure. We give examples of systems that do not admit a dominated splitting but can be shown to have SRB measures using our methods.

BACKGROUND A decoction composed of Adenanthera pavonina L. and Thespesia populnea L. is currently being used in the treatment of cancer patients. METHODS Lactate Dehydrogenase (LDH) release, (3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) MTT, and Sulforhodamine B (SRB) assays were carried out to study cytotoxicity and anti-proliferative activity against the HEp-2 cells, 24 h...

Introduction Anaerobic treatment processes for biodegradation of hazardous materials have increasingly been gaining attention in environmental applications. Microbial processes utilizing sulfate reducing bacteria (SRB), in particular, have found potential applications in variety of treatment processes such as flue gas desulfurization [1,2], gypsum reclamation [3], sulfur recovery from sulfitdsu...

The marine snail Littorina saxatilis exhibits extreme morphological variation between and within geographical regions and represents an excellent model for assessing local adaptation. Previous studies support the hypothesis of parallel evolution in sympatry of two morphologically different ecotypes (named as RB and SU) that co-inhabit different habitats from Galician rocky shores (NW Spain), an...

The vertical distribution of sulfate-reducing bacteria (SRB) in photosynthetic biofilms from the trickling filter of a sewage treatment plant was investigated with oligonucleotide probes binding to 16S rRNA. To demonstrate the effect of daylight and photosynthesis and thereby of increased oxygen penetration, we incubated two 4-mm-thick biofilm samples in darkness or exposed to light at natural ...
