the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
The aim of this study was to record the length-weight relationship and condition factor of A. maculatus from Persian Gulf coastal waters. The specimens were collected on a monthly basis from April to March 2013. Overal 766 specimens were caught. Size and weight of collected fish ranged between 13/2-48 cm and 31.2-1820 gr. The Condition of the growth fish was allometrically negative with b val...
This study examined whether the effectiveness of virtual reality (VR) in science education could be enhanced by providing students with relevant information about VRâs usefulness before a lesson. On basis expectancyâvalue theory, we manipulated studentsâ perceived VR using video priming presenting biology We then assessed how intervention affected presence, interest lesson, and learning a...
condition factor of fish species is very important parameter for understanding fish biology and pathology. for that purpose, we sampled 120 fish individuals from the sava river at four locations (posavina region), where most of them belongs to the cyprinidae family while the others belonging to the families: percidae, siluridae, ameiuridae, esocidae and gobiidae. in total fish sample we found t...
The precise quantitation of activated factors in human factor IX concentrates has been accomplished with the use of recently developed, specific assays for factors IXa, Xa, and thrombin. The assay for factor IXa, which measures the initial rate of 3H-factor-X activation, was shown to be specific for factor IXa in the concentrates. Activated factor IX concentrates contained 1.0-2.3 microgram/ml ...
