Structural damping identification using a recursive Kalman filter

Much research has been done in developing techniques for identifying the structural damping of physical systems. Such techniques are always accompanied by the development of an analytical model of the ideal system and its comparison with experimental data obtained in laboratory. Also, flexible systems are difficult to be modeled, but the authors can use an approximation, supposing that a flexible system, composed by a...

Purification and biochemical characterization of extracellular manganese peroxidase from Ganoderma lucidum IBL-05 and its application

In this study an extracellular manganese peroxidase (MnP) was isolated from culture filtrate of an indigenous fungal strain Ganoderma lucidum IBL-05 under static conditions using wheat bran as substrate. The enzyme was purified by applying successively ammonium sulphate precipitation, dialysis, ion exchange and gel filtration chromatographic techniques. Purification procedure resulted in 3.43-fold purification with...

Effect of magnesium fertilization on some plant nutrient interactions and nut quality properties in Turkish hazelnut (Corylus avellana L.)

Plant nutrient interactions and fertilization is one of the most important factors affecting the quality of hazelnuts. This study aimed to determine the relationships between some plant nutrients and some hazelnut quality criteria and yields. The trial was carried out at Tombul hazelnut orchards in Hazelnut Research Station between 2009 and 2011. The trial was designed as randomized complete blocks of magnesium nutrient...
