OPTIMASI FORMULA HAIR TONIC MIKROEMULSI BIOTIN (VITAMIN B7) DENGAN METODE FACTORIAL DESIGN

Klasifikasi Data Cardiotocography Dengan Integrasi Metode Neural Network Dan Particle Swarm Optimization

Backpropagation (BP) adalah sebuah metode yang digunakan dalam training Neural Network (NN) untuk menentukan parameter bobot yang sesuai. Proses penentuan parameter bobot dengan menggunakan metode backpropagation sangat dipengaruhi oleh pemilihan nilai learning rate (LR)-nya. Penggunaan nilai learning rate yang kurang optimal berdampak pada waktu komputasi yang lama atau akurasi klasifikasi yan...

Biotin: the forgotten vitamin.

When one heats the yolk, changes occur in the fragile elements that serve to support the vital life force within the egg. The egg yolk, in many ways, is not very different from your own cells. Once your temperature goes above 105 degrees you will start to suffer serious health problems. Similarly, heating the yolk above 105 degrees will also start to cause structural changes in many of the high...

Relationships between Biotin and Vitamin B12. Effects of Biotin and Vitamin B12 on Folic Acid Metabolism.

1. The effects of dietary biotin compared with vitamin B(12) on the total content and on the distribution of the various folate derivatives in the liver of rats given a biotin-free diet have been studied. The effect of both vitamins on the conversion in vitro of folic acid into citrovorum factor in the same experimental conditions was also examined. 2. In biotin-treated rats as well as in vitam...

Isolation of Biotin (vitamin H) from Liver*

In the course of our work on the isolation of vitamin H, the antiegg white injury factor, it began to be suspected that vitamin H might be identical with biotin, a yeast growth factor, which had been isolated as the methyl ester from egg yolk by Kijgl and Tennis (2), and with coenzyme R, a growth and respiration factor for rhizobia (3). All the evidence we were able to adduce, experimentally an...
