The open neighborhood of a vertex $v$ of a graph $G$ is the set $N(v)$ consisting of all vertices adjacent to $v$ in $G$. For $Dsubseteq V(G)$, we define $overline{D}=V(G)setminus D$. A set $Dsubseteq V(G)$ is called a super dominating set of $G$ if for every vertex $uin overline{D}$, there exists $vin D$ such that $N(v)cap overline{D}={u}$. The super domination number of $G$ is the minimum car...

Uspanteko is an endangered Mayan language spoken by up to 6000 people in the Guatemalan highlands. We provide overview of phonetics and phonology Uspanteko, focussing on phenomena which are common languages and/or typologically interesting. These include glottalised consonants (ejectives, implosives, glottal stop), uvular consonants, vowel length contrasts, syllable structure, stress, lexical t...

Phonological alternation poses problems for spoken word recognition. In Mandarin Tone 3 sandhi, a Tone 3 syllable changes to a Tone 2 syllable when followed by another Tone 3 syllable. A traditional phonological account assumes that the initial syllable of Mandarin disyllabic sandhi words is Tone 3 (T3) underlyingly, but becomes Tone 2 (T2) on the surface. In an auditory–auditory priming lexica...

Enlargement of Lie super algebra B(0, 1) was given firstly. Then nonlinear super integrable couplings of the super classical Boussinesq hierarchy based upon this enlarged matrix Lie super algebra were constructed secondly. And its super Hamiltonian structures were established by using super trace identity thirdly. As its reduction, special integrable couplings of classical Boussinesq hierarchy ...

decreasing water loss and increasing the irrigation times are basic methods to develop agriculture, success in natural recourse projects, minimize the stress to planted bushes in natural fields and increase the productivity of soil and water sources. the use of super absorbent is one of these strategies to achieve these goals. the main purpose of this research was to study the effect of super a...

amikacin has been shown to irreversibly suppresscochlear activity.the aim of this study is to assess the incidence of amikacinototoxicity in multidrug-resistant tuberculosis patients and riskfactors associated withthis ototoxicity.in this cross-sectional study, 41 patientswith multidrug-resistant tuberculosis (mdr-tb) were included.all patients received fixed dose of intravenous amikacin(500 mg...

rhododendron dauricum l. is an ancient chinese traditional herb. the pharmacological effects of r. dauricum extract have been shown in chronic tracheitis. the aim of this study was to investigate the cardiovascular effects of rhododendron dauricum l. flavonoids (rf) on rats and its mechanisms. this study was performed in isolated vascular rings and a rat model of myocardial infarction and isola...

introduction: the hallmark of vitiligo is the disappearance of melanocytes from the skin due to an as yet unidentified mechanism. the presence of melanocytes in the auditory apparatus suggests that this system could possibly be affected by vitiligo, which targets the melanocytes of the whole body and not just the skin.the purpose of this study was to assess the incidence of auditory alterations...
