Table 4.2 System suitability results for Lamivudine, Zidovudine and Nevirapine Parameters Lamivudine Zidovudine Nevirapine Retention time 2.327 2.864 5.608 Area 212473 338930 228426 USP Plate count 2715.09 3350.07 4979.51 USP Tailing 1.38 1.32 1.18 4.3.1.2 Linearity A linear correlation coefficient factor was obtained between the concentrations of Lamivudine, Zidovudine and Nevirapine versus the peak area. The calibration curves were linear for concentrations between 15-150 µg/mL. The linearity…

A0130036Y Method 1: Box Plot The question asks if Road Handling is part and parcel of Practicality, i.e. whether road handling is an essential component influencing/affecting another data group, practicality. Thus, road handling is taken to be the independent variable, x, and is ranked from the lowest to the highest score. The data is split into 5 groups, Group 1 and 5 containing the lowest-ranked and highest-ranked road handling scores, respectively. Group 1 2 3 4 5 Median 4.58 4.585 4.455…

causes the Y. On the other hand, if the independent variable X does not help to predict Y, then the coefficients on the lags of X will all be zero in the reduced form Y equation. 7. Empirical results 7.1 Optimal lag length selection tests Before testing for the relationship among the selected variables, the optimal lag length is determined. The current study uses three different information criterion procedures, Akaike information criterion (AIC), Schwarz information criterion (SBIC) and…

Study Site We conducted this study at the Scientific Station at Las Joyas (Estación Cientifica Las Joyas) (19o35’20.7”N, 104o15’52.1”W) in the Sierra de Manantlán Biosphere Reserve, Jalisco, Mexico. Elevation reaches about 2400m above sea level. The forests transition from dry-deciduous, pine-oak, and cloud, as the elevation increases. Study Species We studied a white flowered plant with green berries and un-toothed leaves (most likely Solanum schlechtendalianum) from the genus Solanum, as it…

dependent variables and the various scaling variables as the independent variables. Then the p value will be evaluated in order to determine whether the correlation between the variables are significant and we can falsify the null hypothesis and accept the alternative hypothesis that there is a relationship between the body structure and jumping performances of the toads. Toad Gender Mass (g) Body size (mm) Muscle length (mm) Muscle circumference(mm) Max. Jump (mm) 1 M 19 67 20 20 250 2 M 21.5…

The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this…

Life after High School This investigation was to find the change in future aspiration of high school seniors in the US after 9/11. The suggestion was that the economic impact of the attack would cause fewer childten to have the means to enroll in college. However some where divided on the impact it would have on enlistment as wether it would increase due to patriotistic sentiment or decrease with them rise in probability of actual engagement. An unidentified polling organization arranged…

The results of analysis on table 1 presented the demographic characteristics of cattle farmers in the study area. A large proportion were male (95.9%) than the female (4.1%), which is an indication that male participated more than female in the awareness and the use of crop residue urea feeding technology. The findings also revealed that majority (40 – 50 years) of cattle farmers are in their middle ages which implies that age was an important variable as it reflects the physical strength for…

When it comes to individual, everyone has different levels of ability to deal with memory. In reality, you will find many women complaining that their husbands or boyfriends tend to forget their birthdays and anniversaries; and men always explain that they have bad memories. So, is it true that women have a better memory than men? Dose gender affect memory? The evidence shows that gender dose affect memory. In fact, men and women are equally affected by short-term memory loss. Nevertheless,…

Caffeine Impact on Goldfish Metabolism Introduction Metabolism is a process that enable organisms to maintain their life. Metabolism can be measured in numerous parameters. Within this experiment in order to measure the metabolism rate by determined the level of dissolved oxygen. Goldfish is an example of poikilotherm that are organisms that are influenced by the environment surrounding them. Thus, the manipulation of surrounding can influence the metabolism rate due them being ectotherms.…
