Performance Testing of Membrane Electrode Assembly (MEA) with Pt/C Catalyst on PEMFC with Varying Hydrogen Gas Flow Rates has been carried out. MEA was made using a commercial Pt/C catalyst on the cathode combined with a synthetic Pt/C catalyst on the anode and sandwiching a Nafion 212 electrolyte membrane. Tests were carried out with varying hydrogen gas flow rates of 100, 200, 300, and 400 mL…
BSF maggot flour has the highest protein content as well as other ingredients such as carbohydrates, fatty acids, minerals, antimicrobial peptide (AMP), and chitin. BSF maggot flour protein can be utilized by Bifidobacterium bifidum (B. bifidum) to stimulate its growth. The purpose of this study was to determine the potential of BSF maggot flour as a prebiotik by testing its effect, index, and …

This book describes a simplified approach to the modelling and process design of a fixed bed hybrid bioreactor for wastewater treatment. In this work a simplified model for hybrid bioreactor is developed to determine output parameters like exiting substrate concentration in bulk liquid, average substrate flux in the biofilm, effective and total biofilm thickness. The model is based on mass bala…
Backgrounds. Luminal B molecular type breast carcinoma is characterized by ER+, PR+, HER2+/- with high Ki-67 (>20%). The clinicopathological characteristics of luminal B invasive breast carcinoma of no special type varied, from age, menopausal status, parity, and histopathology grade. The aim of this study is to determine the relationship between clinicopathological characteristics with luminal…
