introduction: dentine hypersensitivity (dh) is characterized by a short sharp pain arising from the exposed dentine, in response to a thermal, evaporative, tactile, osmotic or chemical stimulus. the aim of this study was to evaluate the efficacy of nd:yag laser therapy and desensitizing gel (sensikin®, laboratorios kin s.a., barcelona, spain) in treatment of dentine hypersensitivity. methods: a...

Classic techniques for proving termination require the identification of a measure mapping program states to the elements of a well founded domain and to show that this measure decreases with each iteration of a loop in the program. This is a global termination condition — there is a single measure which must be shown to decrease over all of the loops in the program. In this abstract we look at...

for these devices. But the macro layer of a network can be expanded to go a long way. In the near-term, the smartphone challenge is not about providing the capacity to cope with subscriber datausage, but is related to how the signaling system is configured. To build the networks that will cope with long-term predictions requires a new approach to network construction, heterogeneous networks – m...

S tem cell research—and investment into it—has been largely inspired by the hope of using stem cells to regenerate, repair or replace damaged tissue or even whole organs. Stem cell-based therapies promise to eventually solve the problems associated with conventional organ transplantation: notably tissue rejection, a shortage of donors and the poor quality of donor organs. A much improved knowle...

introduction: mass production of natural enemies has been considered a necessity for biological control programs. most beneficial insects have a relatively short shelf-life, so suppliers do not have a sufficient number of biocontrol agents. the development of storage techniques for biocontrol agents provides flexibility and efficiency in mass production. cold storage by prolonging insect develo...

salinity is one of the most important widespread abiotic stresses which causes toxic and nutritional effects as well as loss of water absorption ability by plants. plants respond to salinity with morphological changes. due to high susceptibility of chickpea to salt stress, some physiological and morphological responses occur following the stress in this plant. thus, different concentrations of ...
