the purpose of this paper was to review the commercially available periodontal dressings, their physical and chemical properties, biocompatibility and therapeutic effects. electronic search of scientific papers from 1956 to 2012 was carried out using pubmed, scopus and wiley interscience search engines using the searched terms periodontal dressing, periodontal pack. numerous in vitro and in viv...

at present, many drugs are used for inhibition of uterine contractions, but the proportions of preterm labors are increasing. although magnesium sulfate is the most commonly prescribed parenteral tocolytic agent, but it’s optimal use has yet to be delineated. in this study a high-dose protocol for magnesium sulfate tocolytic therapy was compared with a low-dose regimen. one hundred patients adm...

objective: maintaining the health of oral tissues is a major goal in dentistry. however, limitations in dental materials, instruments, procedures and medications prevent achievement of this goal. advances in nanotechnology have paved the way to approach this goal. this study reviews the advances on nanotechnology in dentistry. review of literatures: in this review study, google scholar, pubmed,...

background:chronic idiopathic thrombocytopenic purpura (itp) is an autoimmune disorder characterized by a low platelet count due to reduced production and higher destruction of the platelets. therapy is aimed at increasing the patient’s platelet count to safe levels and includes a wide variety of treatments, which has a large impact on the patient’s quality of life. health related quality of li...

multi agent markov decision processes (mmdps), as the generalization of markov decision processes to the multi agent case, have long been used for modeling multi agent system and are used as a suitable framework for multi agent reinforcement learning. in this paper, a generalized learning automata based algorithm for finding optimal policies in mmdp is proposed. in the proposed algorithm, mmdp ...

nine organic substrates viz., rice grains, sorghum grains, wheat grains, millet grains, wheat straw, rice husk, cow dung, sawdust, and poultry manure were used for mass multiplication of trichoderma harzianum. of these,sorghum grains followed by millet grains were the best substrates. the poultry manure appeared to be the most unsuitable substrate, whereas rice grains, wheat grains, wheat straw...

in this paper, the optimal adaptive leader-follower consensus of linear continuous time multi-agent systems is considered. the error dynamics of each player depends on its neighbors’ information. detailed analysis of online optimal leader-follower consensus under known and unknown dynamics is presented. the introduced reinforcement learning-based algorithms learn online the approximate solution...

the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...

fluid invasion from water-based drilling mud (wbdm) into the shale formations causes swelling,high pressure zone near the wellbore wall, and eventually wellbore instability problems duringdrilling operations. for the stability of the wellbore, physical plugging of nanoscale pore throats couldbe considered as a logical approach toward avoiding the fluid invasion into the shale formation. thispap...
