Abstract: The advantages of Nannochloropsis oculata include fast growing and high oxygen production. The amount of oxygen production is higher than the dissolved oxygen saturation value of air in water. Therefore, this study aimed to build a photosynthetic fixed-biofilm microbial fuel cell (P-FMFC) system, which compare different growth period of N. oculata as the cathode, and performing power generation. The results showed that:(1) The dissolved oxygen of P-FMFC is 15 mg/L under steady state is better than control (7.1 mg/L); (2) Electricity generation was enhanced significantly with sufficient oxygen as the terminal electron acceptor in the P-FMFC system. Oxygen was provided via photosynthesis with N. oculata in the cathode chamber (3)The growth rate of N. oculata was intended 0.00754 hr-1 when in close circuit, higher than the open circuit 0.00680 hr-1.

Abstract: Brick masonry is one of the earliest types of structures erected by man. Masonry has been used as a load bearing material for centuries. It is the most common type of structures in many countries. It is very weak in resisting earthquake hence the parameters of masonry unit to resist lateral load needs to be known.To find shear and tensile properties of brick masonry unit no standard procedures are introduced in ASTM and ACI. The shear and tensile properties between brick and mortar interface are closely presented in this paper. The objective of this paper is not to develop standard procedure of finding shear and tensile properties of masonry unit rather to develop a preliminary method to find the shear and tensile properties of masonry unit.Various works have been done about compressive strength of mortar. But few works are done about tensile and shear strength of mortar. The shear and tensile strength of mortar between three brick masonry unit are closely studied at various loading co
