the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
BACKGROUND A site near Tuskegee, Alabama was examined for vector-host activities of eastern equine encephalomyelitis virus (EEEV). Land cover maps of the study site were created in ArcInfo 9.2 from QuickBird data encompassing visible and near-infrared (NIR) band information (0.45 to 0.72 microm) acquired July 15, 2008. Georeferenced mosquito and bird sampling sites, and their associated land co...
Kurzfassung Im vorliegenden Beitrag wird die Frage der Beeinflussung der Disziplin Wirtschaftsinformatik durch Modethemen aus wissenschaftstheoretischer Sicht näher untersucht. Auf Basis der Literatur werden Thesen bzgl. wissenschaftspraktischer Kennzeichen (Ursprung, langfristige Lerneffekte) und wissenschaftstheoretischer Fragestellungen (begriffliche Kontingenz, Originalität) aufgestellt. Di...
Background & Aim: Heavy metals are including destructive pollutants of environment which important due to adverse physiological effects on living organisms at low concentrations. Aims of performance this study was to measure the concentration of some heavy metals in industrial dust, as well as evaluate and Spatial Distribution the Toxicity Unit indices and Environmental Risk of metals using kri...
Air pollution is overflowing in big cities, especially in areas where pollution sources and the human population are concentrated. Economic growth and industrialization caused the increasing emissions of air polluting. Then, the quantities of polluting have increased dramatically; the evaluation of a suitable method for predicting and monitoring the pollution will be very important. To prevent ...
A simple but novel and applicable approach is proposed to solve the problem of smoothing effect of ordinary kriging estimate which is widely used in mining and earth sciences. It is based on transformation equation in which Z scores are derived from ordinary kriging estimates and then rescaled by the standard deviation of sample data and the sample mean is added to the result. It bears the grea...
This study proposes a novel measurement-based method to predict and model three-dimensional (3-D) path loss in indoor scenarios, which first regresses 28 GHz measurements via median modeling then includes ordinary Kriging interpolate shadowing. The performance of this is evaluated by investigating the spatial structure that follows shadowing through semivariogram, covariance function, correlogr...
Foumban, located in the Noun valley western Cameroon, is a prime location for food production. However, this locality experiencing significant decline productivity due to acidity of its soil. This linked behaviour certain soil properties essential plant growth. The present work aims study pH as function chemical parameters such CEC, organic matter, exchangeable bases, and aluminum map spatial s...
