Comparison of Persian Language Fricative Consonants Recognition in Babble Noise in Fourth and Fifth Decades of Life

Generally regular communications are performed in the presence of noise Babble noise imposes a negative impact on the speech signal by its nature Consonants play a vital role in the perception of the word meaning From presented samples sixty adults with normal hearing were assessed in this cross- sectional study Once auditory and speech assessment was performed the recognition of fricative consonants as a consonant-vowel-consonant syllable in babble noise was compared in two age groups of 30-39 and 40-49 years old in signal-to-noise ratios of 0 and -5 In the occurrence of certain vowels in 0 and -5 signal-to-noise ratios there was a significant difference between the two age groups of 30-39 and 40-49 years old considering the recognition score of fricative consonants The recognition score of fricative consonants was affected by age signal-to-noise ratio and concurrent vowel Also the recognition scores of sibilant fricative consonants were greater in the babble noise in two age group

The Comparison of Kashshaf Commentary with Safi and Shawahid Al-Tanzil Commentaries in Terms Of Infallible Imams' Status

Most Shia Commentators such as Feiz Kashani and several Sunni commentators such as Zamakhshari and Haskani have long tried to match some Quranic verses with Holy Prophet's household in their commentaries, based on the traditions related to their occasions of revelation. The present paper seeks to reanalyze such matching in their commentaries. The findings indicate although Zamakhshari have explained the occasions of revelation in details, he has referred and explained only %10 (21 out of 200) of verses related to the virtues of Holy Prophet's household, and very few of infallible Imams' virtues below these verses. He has avoided not only mentioning the verses related to the virtues of the Holy Prophet's household with widely transmitted occasions of revelations, but also analyzing them. On the contrary, Haskani has discussed infallible Imams' virtues and merits through general methods in his Shawahid Al-Tanzil Commentary, using more than 1200 traditions below 210 verses; and Feiz Kashani has explained and clarified infallible Imams' virtues in his Safi Commentary, using particular methods

Sensitivity and specificity of chest computed tomography scan based on RT-PCR in COVID-19 diagnosis

Purpose: COVID-19 is a novel, severely contagious and progressive infection occurring worldwide. The diagnosis of the disease is based on real-time polymerase chain reaction (RT-PCR) and computed tomography (CT) scan, even though they are still controversial methods. Material and methods: We studied 54 patients with suspected COVID-19 and the two mentioned methods were compared with each other. Results: Sensitivity and specificity of the abnormal chest CT scan, ground-glass opacity (GGO), consolidation opacity, and both of GGO and consolidation were also surveyed based on RT-PCR. The results showed that RT-PCR assay was negative in 23 (42.6%) patients and positive in 31 (57.4%) cases. Also, the patients with an abnormal chest CT scan comprised 37 (68.5%). The sensitivity and specificity of abnormal CT scan were 78.6% and 42.3%, respectively, based on the RT-PCR method. Conclusions: Other techniques alongside CT scan and RT-PCR are advocated for accuracy of the COVID-19 diagnosis

The comparison of plasma fibronectin in term and preterm delivery: A cross-sectional, descriptive-analytical study

Background: Preterm delivery is one of the main causes of infant death. Therefore, prediction of preterm delivery may eliminate a large number of prenatal complications. Objectives: The present study aimed to understand if preterm delivery can be predicted by assessing maternal plasma fibronectin concentration. Materials and Methods: Serum samples from 105 pregnant women participating in this study were collected. The plasma fibronectin were measured at 24-28 wk of gestation and again at 32-36 wk of gestation. Unfortunately, only 65 of the 105 pregnant women, returned for the second sampling. The plasma fibronectin was analyzed using ELISA method and its concentration in term and preterm deliveries was compared. The delivery dates of all the women were also recorded. Results: Out of 105 pregnant women, 28 delivered preterm (26.7%). The Plasma fibronectin concentrations in women with preterm delivery were higher than in those who delivered at term (p = 0.001). Accordingly, Plasma fibronectin concentrations were significantly higher in the second serum samples (p = 0.01). Plasma fibronectin concentrations was also higher in obese women and in those suffering from preeclampsia (p = 0.12) and gestational diabetes (p = 0.81). Conclusion: Plasma fibronectin concentrations test could be used as an optional screening test for preterm delivery at 28 to 34 wk of gestation in pregnant women who prefer to avoid vaginal sampling. Key words: Premature birth, Fibronectin, Maternal serum screening tests

Measurement Invariance and Psychometric Analysis of Oxford Happiness Inventory Scale across Gender and Marital Status

Background: The Oxford Happiness Inventory (OHI) is a self-report tool to measure happiness. A brief review of previous studies on OHI showed the lack of evaluation of OHI fairness/equivalence in measuring happiness among identified groups. Methods: To examine the psychometric properties and measurement invariance of the OHI, responses of 500 university students were analyzed using item response theory and ordinal logistic regression (OLR). Relevant measures of effect size were utilized to interpret the results. Differential test functioning was also evaluated to determine whether there is an overall bias at the test level. Results: OLR analysis detected four items across gender and two items across marital status to function differentially. An assessment of effect sizes implied negligible differences for practical considerations. Conclusions: This study was a significant step towards providing theoretical and practical information regarding the assessment of happiness by presenting adequate evidence regarding the psychometric properties of OHI
