No human data was found on teratogenicity or reproductive effects of Dicamba (NPIC‚ 2012). The chart (NPIC‚ 2012) below contains the toxicity classification for Dicamba regarding the acute oral‚ inhalation‚ dermal‚ primary eye irritation‚ and primary skin irritation effects. It is important to note that not a lot of information is available regarding the chronic toxicity of Dicamba in humans‚ the U.S. EPA has not found any evidence regarding Dicamba disrupting the Endocrine system‚ and Dicamba is

Results GWC program participation might contribute to STEM identity‚ but that effect might differ across GWC levels that indicate participants’ prior experience in computer science. Furthermore‚ the effect of program participation might differ across race as well. In order to measure the differences in STEM identity over time by GWC level and race‚ a 2X2x4 mixed design repeated measures ANOVA was conducted. Time was the within-subjects variable with two levels (pre and post). GWC level (beginner

Considering the support for both context-dependant memory and state-dependant memory‚ it is reasonable to theorize that there should be an effect of music-dependent memory as well. Music-dependant memory then‚ is an extension of both context-dependant memory and state-dependant memory that assumes that it is easier for an individual to recall information while listening to the same music that was playing when the individual encoded the information. This is especially potent when you consider the

The analysis for the Bilingual Education Attitudes Survey theorizes that items in the survey have a strong correlation‚ which demonstrates evidence for construct validity. Measuring both the convergent and discriminant validity supports this theory because in Table 1‚ there is a very strong positive correlation between the first administration (r= .91) and a strong positive correlation with the second administration (r= .86)‚ in relation to the previously validated bilingual education scale.

For Acidic hydrolysis‚ SAC was found to be well susceptible to acid hydrolysis with 0.05 M HCl at 40 ˚C for 30 min caused about 8% reduction in the peak area of SAC (Fig.4a). While this mild condition didn’t affect VAL. While‚ nearly 27% was the reduction in SAC’s peak area when subjected to alkaline hydrolysis. This considerable decline in the peak area of SAC when subjected to 0.01 M NaOH at 40°C for 30 min revealed degradation products peaks appeared at 3.339 and 9.482 minutes (Fig.4b) and they
