objective: extraction of premolars is believed to affect the eruption of third molars. this comparative study aimed to assess the change in angulation of third molars following first/second premolar extraction versus non-extraction orthodontic treatments. methods: this historical cohort study was conducted on patients assigned to three treatment groups: extraction of mandibular first premolars ...

There is emerging evidence for multifarious neurological manifestations of coronavirus disease 2019 (COVID-19), but little known regarding whether they reflect structural damage to the nervous system. Serum neurofilament light chain (sNfL) a specific biomarker neuronal injury. We measured sNfL concentrations 29 critically ill COVID-19 patients, 10 non–COVID-19 and 259 healthy controls. After ad...

background: some coincidental disorders with migraine have been introduced that may have role in its pathogenesis or aggravation. in this study we determined the relative frequency of hyperlipidemia as a coincidental disorder in patients affected by migraine. methods: a total of 102 migraine-affected patients according to international headache society (his) criteria and 103 control subjects ad...

Today, various structural and non-structural solutions are used to control and reduce the negative effects of floods in investigation and executive projects. But what is certain is that the optimal solution to minimize flood damage is a combination of structural and non-structural methods (planning and response measures). It is essential to provide these solutions in a metropolis like Tehran be...

Finite projective (lattice) geometries defined over rings instead of fields have recently been recognized to be of great importance for quantum information theory. We believe that there is much more potential hidden in these geometries to be unleashed for physics. There exist specific rings over which the projective spaces feature two principally distinct kinds of basic constituents (points and...

The study objective was to compare qualitatively the clinical features of patients with electrical status epilepticus in sleep with focal versus generalized sleep potentiated epileptiform activity. We enrolled patients 2 to 20 years of age, studied between 2001 and 2009, and with sleep potentiated epileptiform activity defined as an increase of epileptiform activity of 50% or more during non-ra...

Abstract This study investigates and compares born global (BG) firms non-BG in Malaysia. We employed the multigroup analysis technique with structural equation models to test six hypotheses determine differences similarities between two proposed of BG across a wide range industries. The reveals antecedents marketing capabilities for BGs versus non-BGs, indicating that performance enabling mecha...

nowadays, due to the competitive conditions of global market, corporations try to outsource their extraneous processes to third-party suppliers. so, selecting a proper supplier play a significant role in organization success. the supplier selection problem can be viewed as a group decision-making problem with multiple criteria. since in previous researches the inter relationship between criteri...
