| 1 | A methodology to determine the elastic properties of anisotropic rocks from a single uniaxial compression test显示文摘This paper introduces a new methodology to measure the elastic constants of transversely isotropic rocks from a single uniaxial compression test.We first give the mathematical proof that a uniaxial compression test provides only four independent strain equations.As a result,the exact determination of all five independent elastic constants from only one test is not possible.An approximate determination of the Young’s moduli and the Poisson’s ratios is however practical and efficient when adding the Saint-Venant relation as the fifth equation.Explicit formulae are then developed to calculate both secant and tangent definitions of the five elastic constants from a minimum of four strain measurements.The results of this new methodology applied on three granitic samples demonstrate a significant stress-induced nonlinear behavior,where the tangent moduli increase by a factor of three to four when the rock is loaded up to 20 MPa.The static elastic constants obtained from the uniaxial compression test are also found to be significantly smaller than the dynamic ones obtained from the ultrasonic measurements. | Morteza Nejati Marie Luise Texas Dambly Martin OSaar | 2019 | Journal of Rock Mechanics and Geotechnical Engineering2019，11，6： | 3 |
| 2 | Transcranial Direct Current Stimulation in ADHD:A Systematic Review of Efficacy,Safety,and Protocol-induced Electrical Field Modeling Results显示文摘Transcranial direct current stimulation(tDCS)is a promising method for altering cortical excitability with clinical implications.It has been increasingly used in neurodevelopmental disorders,especially attention-deficit hyperactivity disorder(ADHD),but its efficacy(based on effect size calculations),safety,and stimulation parameters have not been systematically examined.In this systematic review,we aimed to(1)explore the effectiveness of tDCS on the clinical symptoms and neuropsychological deficits of ADHD patients,(2)evaluate the safety of tDCS application,especially in children with ADHD,(3)model the electrical field intensity in the target regions based on the commonly-applied and effective versus less-effective protocols,and(4)discuss and propose advanced tDCS parameters.Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses approach,a literature search identified 14 empirical experiments investigating tDCS effects in ADHD.Partial improving effects of tDCS on cognitive deficits(response inhibition,working memory,attention,and cognitive flexibility)or clinical symptoms(e.g.,impulsivity and inattention)are reported in10 studies.No serious adverse effects are reported in 747 sessions of tDCS.The left and right dorsolateral prefrontal cortex are the regions most often targeted,and anodal tDCS the protocol most often applied.An intensity of 2 mA induced stronger electrical fields than 1 mA in adults with ADHD and was associated with significant behavioral changes.In ADHD children,however,the electrical field induced by 1 mA,which is likely larger than the electrical field induced by 1 mA in adults due to the smaller head size of children,was sufficient to result in significant behavioral change.Overall,tDCS seems to be a promising method for improving ADHD deficits.However,the clinical utility of tDCS in ADHD cannot yet be concluded and requires further systematic investigation in larger sample sizes.Cortical regions involved in ADHD pathophysiology,stimulation parameters(e.g.intensity,duration,polarity,and electrode size),and types of symptom/deficit are potential determinants of tDCS efficacy in ADHD.Developmental aspects of tDCS in childhood ADHD should be considered as well. | Mohammad Ali Salehinejad Vahid Nejati Mohsen Mosayebi-Samani Ali Mohammadi Miles Wischnewski Min-Fang Kuo Alessio Avenanti Carmelo M・Vicario Michael A.Nitsche | 2020 | Neuroscience Bulletin2020，36，10： | 3 |

| 4 | Evaluation of factors affecting psychological morbidity in emergency medicine practitioners显示文摘BACKGROUND: Assessing and evaluating mental health status can provide educational planners valuable information to predict the quality of physicians' performance at work. These data can help physicians to practice in the most desired way. The study aimed to evaluate factors affecting psychological morbidity in Iranian emergency medicine practitioners at educational hospitals of Tehran.METHODS: In this cross sectional study 204 participants(emergency medicine residents and specialists) from educational hospitals of Tehran were recruited and their psychological morbidity was assessed by using a 28-question Goldberg General Health Questionnaire(GHQ-28). Somatization, anxiety and sleep disorders, social dysfunction and depression were evaluated among practitioners and compared to demographic and job related variables.RESULTS: Two hundreds and four participants consisting of 146(71.6%) males and 58(28.4%) females were evaluated. Of all participants, 55(27%) were single and 149(73%) were married. Most of our participants(40.2%) were between 30–35 years old. By using GHQ-28, 129(63.2%) were recognized as normal and 75(36.8%) suffered some mental health disorders. There was a signifi cant gender difference between normal practitioners and practitioners with disorder(P=0.02) while marital status had no significant difference(P=0.2). Only 19(9.3%) declared having some major mental health issue in the previous month.CONCLUSION: Females encountered more mental health disorders than male(P=0.02) and the most common disorder observed was somatization(P=0.006). | Mehdi Momeni Farshid Fahim Elnaz Vahidi Amir Nejati Morteza Saeedi | 2016 | World Journal of Emergency Medicine2016，7，3： | 2 |
| 5 | Some ecological attributes of malarial vector Anopheles superpictus Grassi in endemic foci in southeastern Iran显示文摘Objective:To determine the bionomics and susceptibility status of the malarial vector Anopheles superpictus(An.superpictus)to different insecticides in the Sistan-Baluchestan province which has the highest malarial prevalence in Iran.Methods:Different sampling methods,in addition to scoring abdominal conditions,were used to define the seasonal activity and endo/exophilic behavior of this species.In addition,the standard WHO susceptibility tests were applied on adult field strains.Results:Most adult mosquitoes were collected from outdoor shelters.The peak of seasonal activity of An.superpictus occurred at the end of autumn.Most larvae were collected from natural and permanent breeding places with full sunlight and no vegetation.Blood feeding activities occurred around midnight.Compared with the abdominal conditions of adult mosquitoes collected indoors,the abdominal conditions of adult mosquitoes collected outdoors were gravid and seniigravid.This species was suspected to be resistant to DDT,but was susceptible to other insecticides.Conclusions:An.superpictus was present in almost all outdoor shelters,and the ratios of gravid,semigravid/unfed,and freshly fed confirmed that this species had a higher tendency to rest outdoors than indoors.This behavior can protect An.superpictus from indoor residual spraying in this malarious area.To the best of our knowledge,this is the first report on the susceptibility status of An.superpictus in Southeastern Iran.We do not suggest the use of DDT for indoor residual spraying in southeast Iran. | Jalil Nejati Hasan Vatandoost Mohammad Ali Oshghi Masud Salehi Ehssan Mozafari Seyed Hasan Moosa-Kazemi | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，12： | 2 |
