Microorganisms have the ability to secrete enzymes when they are grown in the presence of certain substrates. Amylases are among the most important industrial enzymes and are of great significance in biotechnological studies. Bacteria belonging to the gen... see more

The clogging in the Submerged Entry Nozzle (SEN), responsible for controlling the steel flow in continuous casting, is one of the main problems faced by steelmaking process, since it can increase the frequency of interruptions in the operation for the mai... see more

Pectinases are the group of enzymes that degrade pectin. This study was conducted with the aim of isolation of efficient pectinase producing pectinolytic fungi from the decomposing mango peels using extracted mango peels pectin as a growth substrate under... see more

Asam sitrat merupakan salah satu bahan tambahan makanan minuman yang paling sering digunakan para produsen, karena mudah didapatkan dan keamanannya bagi kesehatan. Namun kebutuhan para produsen terhadap asam sitrat tersebut belum dapat tercukupi sepenuhny... see more

 The expensive price of glucoamylase is due to the high cost of enzyme production. Utilization biomass is expected to be an alternative raw material to reduce the cost of producing enzymes without reducing the quality of the product. Aspergillus awam... see more

This paper presents an experimental study on wave reflection from submerged rectangular objects (shelves) in a 2-D laboratory flume. Preliminary tests using resistive wire probes and an acoustic Doppler anemometer were first conducted to confirm that a pi... see more

The purpose of the present study was to analyze the performance of reinforced concrete with 28-day compressive strength of 25 MPa and cement content of 300 kg/m³ used in caissons sustaining two wharfs on the Mediterranean coast. The caissons studied are p... see more

Underwater acoustic power around a submerged body in shallow water was investigated using the Boundary Element Method (BEM). The model domain simulated a nearshore environment with shallow water conditions. The seabed was assumed flat and sound velocity w... see more

EComposite hardfacings produced by Plasma Transferred Arc Welding (PTAW) and Submerged Arc Welding (SAW) possess a good combination of hardness, wear resistance and fracture toughness, thus providing high wear resistance. Although they cannot substitute a... see more
