In this paper, the authors present new indices for estimating technical change, return to scale, and TFP growth, as well as its decomposition. These indices, Modified General Index (MGI), Generalized Modified General Index (GMGI), and General Time Trend index (GTTI), are generalization of General Index approaches. These approaches were used for productivity decomposition of Iran's barely produc...

The effective earth radius can transform the curved ray path into a straight line, and modified refractive index spherical ground plane. Using them simplify propagation modeling of electromagnetic waves in atmosphere, so they are widely used calculation long-range wave, adopted by ITU Recommendations IEEE Standards. In this paper, upon employing simple geometric methods, we provide general form...

let g be a connected simple (molecular) graph. the distance d(u, v) between two vertices u and v of g is equal to the length of a shortest path that connects u and v. in this paper we compute some distance based topological indices of h-phenylenic nanotorus. at first we obtain an exactformula for the wiener index. as application we calculate the schultz index and modified schultz index of this ...

Agovernmentshouldusesocialmediaforcommunicatingwithitscitizen.Theengagement index score is one of the methods for assessing the rate of governmental success in using social media as a tool in establishing interactive relationships with its citizen. In general, the engagement index score is obtained by calculating the number of posts, number of likes and comments, and so forth on a single social...

Background: Musculoskeletal disorders, like Low Back Pain (LBP) are associated with impaired lumbopelvic motor control. The current study aimed to investigate the effect of modified Pilates exercises on pain, disability, and lumbopelvic motor control in patients with chronic LBP. Methods: In this randomized controlled single-blind clinical trial, 30 chronic patients with chronic LBP were selec...

Background According to EU legislation, genetically modified plants (GM plants) should follow a scientific assessment of any risk that they may pose to human and animal health, including an allergenicity assessment. According to the EFSA guidance, the allergenicity assessment of GM plants is structured into the assessment of i) the newly expressed proteins and ii) the whole GM plant. For the la...

soil contamination significantly reduces environmental quality and affects human health. to investigate and assess the effects of land use on the concentrations of some heavy metals in surface soils of golestan province, 227 soil samples (0-60 cm) were collected from three types of land uses including agricultural lands, natural, and industrial areas. the total metals and metalloids (cr, se, as...
