Henna leaves (lawsonia inermis) is one of the natural ingredients used to color the skin. It is used as a natural coloring skin which is not used because people tend to choose instant henna. To optimize the use of henna leaves, the author uses mordan lemon and charcoal adsorbent as a generator for the color of henna leaves. This study aims to see the effect of the use of lemon mordan and charcoal adsorbent toward the result of henna leaves color. This research is using experimental method. The subject of the study is the hand’s skin called palm where the samples were taken from 3 students who were treated by 3 different henna leaves. The result showed that, obtained colors (hue) produced on the coloring of the skin using the leaves of a boyfriend without mordan namely 4 panelists or 66.67% stated apricots, 1 panelist or 16.67% stated Carrot and 1 panelist or 16.67 % declares Ocher. The color of the henna leaves without using mordans, namely apricot orange. The results of the panelist's assessment of coloring using the henna leaves with lemon mordan 5 panelists or 83.33% stated Squash, 1 panelist or 16.67% stated Ginger and the direction of the resulting color is dark orange. While the color result of using henna leaves with lemon mordans and charcoal adsorbent 6 panelists or 100% declared Bronze, color direction resulted was copper orange. It proves that there is an effect of using lemon mordan and charcoal adsorbent on skin coloring using henna leaves. Based on the normality testing that has been done, it is obtained that the data is normally distributed. The homogeneity testing that has been done is obtained that the three data have the same variant (homogeneous). Based on the ANOVA test obtained Fcount of 4.375, while the value of Ftable is 3.34. thus Fcount> Ftable (4.375> 3.34) this proves that the hypothesis that reads there is no difference in the results of dark bright colors (value) on skin coloring using henna leaves without the use of mordan, using mordan lemon, and mordan lemon (citrun) with charcoal adsorbent rejected. For further research it is recommended to examine the effect of using mordan alum on the results of henna leaf color. Keywords: henna, mordant , adsorben

Two of the biggest challenges in building models for detecting emotions from electroencephalography (EEG) devices are the relatively small amount of labeled samples and the strong variability of signal feature distributions between different subjects. In this study, we propose a context-generalized model that tackles the data constraints and subject variability simultaneously using a deep neural network architecture optimized for normally distributed subject-independent feature embeddings. Variational autoencoders (VAEs) at the input level allow the lower feature layers of the model to be trained on both labeled and unlabeled samples, maximizing the use of the limited data resources. Meanwhile, variational regularization encourages the model to learn Gaussian-distributed feature embeddings, resulting in robustness to small dataset imbalances. Subject-adversarial regularization applied to the bi-lateral features further enforces subject-independence on the final feature embedding used for emotion classification. The results from subject-independent performance experiments on the SEED and DEAP EEG-emotion datasets show that our model generalizes better across subjects than other state-of-the-art feature embeddings when paired with deep learning classifiers. Furthermore, qualitative analysis of the embedding space reveals that our proposed subject-invariant bi-lateral variational domain adversarial neural network (BiVDANN) architecture may improve the subject-independent performance by discovering normally distributed features.

The overlapping of the sciences is made the subject of much rhetorical writing now-a-days, and its appreciation is one of the most prominent signs of the modern development of the doctrine of Continuity which has been so fruitful in the Philosophy of Discovery. The boundary-line which once separated the geologist and ethnologist has in consequence of this development entirely disappeared, and every one now admits as a postulate that between the two sciences there is a stretch of neutral ground belonging to neither exclusively, and where the students of each must of necessity reap if their harvest is to be complete. Not only so, but it is beginning to be seen that the methods and the directions of the arguments in each science being more or less different—the one partaking much more of the historical, and the other of the experimental method—that it is well that where they overlap the results of each should be closely compared, and thus not only secure a double modicum of certitude, but also suggest fresh veins of untried material where we may put in our mattock with renewed hope of solving some apparently hopeless problems.
