In this study, the effect of flame intrinsic instability on the flame structural characteristics of hydrogen/air mixtures premixed at various equivalence ratios were experimentally investigated from the macroscopic and microscopic perspectives, respectively. The correlation degree and the relative deformation degree were defined to quantitatively study the global flame structural characteristic...
Growth and body height have always been interesting topics in the public opinion. Particularly the stupendous increase of some 15 to 19 cm in final adult height during the last 150 years in most European countries (the “secular trend”), the concomitant changes in body and head proportions, the tendency towards early onset of sexual maturation, the changes in the age when final height is being r...
This paper provides new evidence regarding the impact of the HIV/AIDS epidemic on trend per capita growth in Africa. Panel data from 35 African countries is used to analyze the impact of HIV prevalence on the components of an augmented neo-classical growth model. Results show that HIV prevalence has a significant negative impact on trend per capita growth and its determinants, but only in high ...
PURPOSE To compare the change in ocular axial length of the pseudophakic eye versus the fellow eye in children with bilateral cataracts who had surgery in only one eye. METHODS In this prospective cohort study, 50 eyes of 25 children with bilateral lamellar cataracts were analyzed. A complete ophthalmic examination and evaluation of axial length measurements by contact ultrasound biometry wer...
We study the implications of trend inflation for an economy’s long-run growth rate. To do so, we extend a New Keynesian model to allow for endogenous growth. The defining characteristic of the New Keynesian framework is that inflation and nominal price stickiness together induce relative price dispersion and thus reduce monopoly profits. When the framework is embedded in an endogenous growth mo...
biofertilizers are natural inputs that can be applied as complement or substituent of chemical fertilizers in sustainable agriculture. effects of n and p bio- and chemical fertilizers on growth indices of maize (zea mays l.) was studied on 2008 in shushtar, iran, based an as a factorial experiment based on completely randomized block design with three replications. treatments consisted four lev...
251 specimens of kutum fish caught by bony fish persine on the southern shores of the Caspian Sea (Mazandaran) during the years 2017-2019 were studied to study the growth trend of this species. In this study, maximum estimated length (L∞) and annual growth coefficient (K) of kutum fish were estimated 71.79 cm and 0.13, respectively. The results of natural reproduction of this species in Kheirud...
this study describes the length-weight and length-length relationships for 28 populations of garra ruffa in different basins of iran, including tigris, karkheh, karun, persis and hormuz. the length-weight relationships from most localities are reported here for the first time. for most populations the b value was not significantly different from 3, indicating an isometric growth, in a few, it w...
BACKGROUND Previous studies have suggested that elevated exposure to disinfection by-products (DBPs) in drinking water during gestation may result in adverse birth outcomes. However, the findings of these studies remain inconclusive. OBJECTIVE The purpose of our study was to examine the association between blood biomarkers of late pregnancy exposure to trihalomethanes (THMs) in drinking water...
