Background and aims: New dentin bonding agents and techniques have been developed to reduce microleakage and create higher bond strength. This in-vitro study compared the microleakage of three resin-based adhesives versus a GIC-based adhesive on class V composite restorations.  Materials and Methods: Class V cavities were prepared on the buccal surfaces of 72 sound premolars, randomly assigned ...

the purpose of the present research was to study the effect of cooperative methodology on the social skill development of the primary students. the methodology was quasi-experimental, with pre-test, post-test, and control group. the population of the research was all 486 ‘laleh’ primary school male students in the year of 2009-2010, among whom, 61 four-grade participants were finally chosen. th...

To investigate the effects of different glossing conventions on vocabulary recognition and recall, 158 participants were given a pre-test to make sure that they did not have any prior knowledge of the target words. Reading passages with four different glossing conventions (interlinear, marginal, pre-text, and post-text) were given to eight groups. Four groups received interlingual glosses and f...

a result of dixon‎, ‎evans and smith shows that if $g$ is a locally (soluble-by-finite) group whose proper subgroups are (finite rank)-by-abelian‎, ‎then $g$ itself has this property‎, ‎i.e‎. ‎the commutator subgroup of $g$ has finite rank‎. ‎it is proved here that if $g$ is a locally (soluble-by-finite) group whose proper subgroups have minimax commutator subgroup‎, ‎then also the commutator s...

previous studies have suggested that ketamine, an n-methyl-d-aspartate (nmda) receptor antagonist, provides a pre-emptive analgesic effect and pre-emptive analgesia improves postoperative pain management. the aim of this study was to determine the effict of pre-incisional vs. post-incisional intravenous low dose of racemic ketamine in postoperative pain in children undergoing inguinal hernia re...

‎‎For a finite group $G$ and a subgroup $H$ of $G$‎, ‎the relative commutativity degree of $H$ in $G$‎, ‎denoted by $d(H,G)$‎, ‎is the probability that an element of $H$ commutes with an element of $G$‎. ‎Let $mathcal{D}(G)={d(H,G):Hleq G}$ be the set of all relative commutativity degrees of subgroups of $G$‎. ‎It is shown that a finite group $G$ admits three relative commutativity degrees if a...

in this paper, we consider groups with points which were introduced by v.p. shunkov in 1990. in novikov-adian's group, adian's periodic products of finite groups without involutions and olshansky's periodic monsters every non-unit element is a point. there exist groups without points. in this article we shall prove some properties of the groups with points.

background the imbalance in the t helper (th) 1/th2 and th1/t regulatory (treg) cells-related immune responses plays a key role in pathogenesis of allergic asthma. objectives the aim of this study was to evaluate the effects of cpg-oligodeoxynucleotide (cpg-odn), monophosphoryl lipid a (mpla) and bacillus calmette-guerin (bcg) on the ratio of th1/th2 and th1/treg cells-related parameters in an ...
