background: the aim of the present study was to investigate the quality of root canal obturation performed by 6th year undergraduate dental students at the dental school, university of mashhad, iran. materials and methods: a random 200 sample records of patients who received endodontic treatment at the dental school, university of mashhad between 2009 and 2010 was investigated. the quality of r...

The ratios ${R}_{\ensuremath{\tau}/P}\ensuremath{\equiv}\mathrm{\ensuremath{\Gamma}}(\ensuremath{\tau}\ensuremath{\rightarrow}P{\ensuremath{\nu}}_{\ensuremath{\tau}}[\ensuremath{\gamma}])/\mathrm{\ensuremath{\Gamma}}(P\ensuremath{\rightarrow}\ensuremath{\mu}{\ensuremath{\nu}}_{\ensuremath{\mu}}[\ensuremath{\gamma}])$ ($P=\ensuremath{\pi}$, $K$) provide sensitive tests of lepton universality $|{...

Gas leaks are a significant problem since they may have disastrous effects on infrastructure, human health, and greenhouse gas emissions, among other things. A method for early detection alerting of is required to reduce these dangers. In this project, we suggest low-cost efficient cloud-based Internet Things (IoT) leak system usage in residential, commercial, industrial contexts. An Arduino Un...

A candidate triple strange pentaquark state, ${P}_{csss}$, is investigated through its strong decay channel ${P}_{csss}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}J/\ensuremath{\psi}$. To calculate the relevant coupling constants, two possible interpolating currents with spin-parity ${J}^{P}={\frac{1}{2}}^{\ensuremath{-}}$ are used. Though chosen for state under consi...

In this paper we defined the concept of module amenability of Banach algebras and module connes amenability of module dual Banach algebras.Also we assert the concept of module Arens regularity that is different with [1] and investigate the relation between module amenability of Banach algebras and connes module amenability of module second dual Banach algebras.In the following we studythe...

Glucagon-like peptide-1(7-36NH2) (GLP-1) and peptide YY(3-36NH2) (PYY(3-36NH2)) are cosecreted from the intestine in response to nutrient ingestion. Peripheral administration of GLP-1 or PYY(3-36NH2) decreases food intake (FI) in rodents and humans; however, the exact mechanisms by which these peptides regulate FI remain unclear. Male C57BL/6 mice were injected (ip) with exendin-4(1-39) (Ex4, a...

The internet of things (IoT) has a significant impact on increasing the efficiency and quality electricity in large power systems. Smart voltage current monitoring systems (SVCMS) have been developed using novel method. Using an Arduino Uno microcontroller Wi-Fi module, integrated SVCMS design measures sensor findings sends processed data to Android phone. In order communicate, global for mobil...

RESULTS: Mean follow-up was 14.2 7.8 months. Preoperative uncorrected distance visual acuity (UDVA) was counting fi ngers in all patients. Mean fi nal logMAR (Snellen equivalent) UDVA and corrected distance visual acuity (CDVA) were 0.15(20/28) 0.13 and 0.11(20/26) 0.10, respectively. The improvements in UDVA and CDVA were statistically signifi cant (P .0001 and P .002, respectively). All patie...
