This paper deals with an inspection of defects including corrosion and leakage by Acoustic Emission (AE) in an oil tank floor. In contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in AE method in order to inspection. In this research AE investigation and AE source location is presented in detail. The resul...

The filamentous fungus Neurospora crassa is a model laboratory organism, but in nature is commonly found growing on dead plant material, particularly grasses. Using functional genomics resources available for N. crassa, which include a near-full genome deletion strain set and whole genome microarrays, we undertook a system-wide analysis of plant cell wall and cellulose degradation. We identifie...

Neurospora crassa colonizes burnt grasslands and metabolizes both cellulose and hemicellulose from plant cell walls. When switched from a favored carbon source to cellulose, N. crassa dramatically up-regulates expression and secretion of genes encoding lignocellulolytic enzymes. However, the means by which N. crassa and other filamentous fungi sense the presence of cellulose in the environment ...

BACKGROUND Economical production of fuels and chemicals from plant biomass requires the efficient use of sugars derived from the plant cell wall. Neurospora crassa, a model lignocellulosic degrading fungus, is capable of breaking down the complex structure of the plant cell wall. In addition to cellulases and hemicellulases, N. crassa secretes lytic polysaccharide monooxygenases (LPMOs), which ...

Most common tumors of the spleen are hematologic and lymphoid malignancies. Non-lymphoid and non-hematologic tumors of the spleen are very rare, the most common of which are vascular tumors. This group of tumors in the spleen is composed of heterogeneous tumors such as hemangioma, angioendothelioma (AE), littoral cell angioma, and angiosarcoma. There are several histologic forms of AE such as e...

Two kynureninase activities are known in Neurospora crassa, one of which (kynureninase I) is inducible, the other (kynureninase II) being constitutive. A method is described for the isolation of low-kynureninase mutants of N. crassa. When grown on an inducer, the mutants show significantly less kynureninase I activity compared with wild type, whereas constitutive kynureninase II activity is una...

Background: Artichoke extract (AE), containing natural antioxidant compounds, can be considered as a good source of antioxidant potential. OBJECTIVES: The aim of this study was to evaluate antioxidant abilities of AE on broiler meat quality. METHODS: 200 Ross chicken broilers were divided into five equal groups and received 100, 200, 300, and 500 mg/liter of AE in drinking water and pure water ...
