Transcription factor GATA-1 was first identified in erythroid cells, but later shown to also be expressed Sertoli cells of the mouse testis. transcription testis initiates from a different exon (exon IT) than mRNA (transcribed IE). To begin address question how expression might differentially regulated and we have cloned determined structure IT promoters both rat genes. The regulatory mechanism(s) controlling synthesis IT-derived investigated by transfection wild-type mutant reporter genes,...

In this study, an algorithm for sorting waste products that is capable of automatically determining the value raw materials during process proposed. The measures sum top surface areas integrated circuits (ICs), memory assemblies, and connectors (which account over 80% resource value) from two-dimensional (2D) digital images printed circuit boards. directly correlated with total value. This continuously identifies characteristics (e.g., color, size, shape) each device performs relatively...

Using computational fluid dynamics software, two-dimensional (2D) and three-dimensional (3D) simulation models for simulating the mosaic embedding iron ore sintering (MEBIOS) process were developed on basis of concept multiply shared space (MUSES) method. When one pellet (diameter: 15 mm) was placed at centre a bed, estimated time variations temperature surface by both 2D 3D simulations similar to corresponding experimental results. The calculated cooling rate comparatively high; however, it...

In order to clarify the mechanism of electrical-tree inception and propagation from a water tree within polyethylene, we have investigated temperature dependence electrical water-tree degradation. samples with area above ca. 5000 mum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , ac voltage increased increasing degradation in high as well room temperature. This is explained by moderation field region tree. less than without tree,...

The authors are developing a thermal jet dryer (TJD), with vertical disc-shaped drying tank, for the purpose of weight and volume reduction solid wastes high water content, such as organic sludges. In order to obtain performance TJD, experiments using three kinds were carried out. following results obtained: (1) Drying depended most on disintegration characteristics sample. (2) There was little influence samples' properties gas–solid multiphase flow in tank. (3) critical feed rate at which...

The authors are developing a thermal jet dryer (TJD) with vertical disc-shaped drying tank for the purpose of reducing volume solid wastes high water content, such as organic sludges. In order to obtain characteristics air-particle multiphase flow in TJD, cold model experiments and computational fluid dynamics (CFD) simulations were conducted. following results obtained: (1) A combined eddy was generated tank, cyclone separator. (2) “Cascading” phenomena occurred particle discharging...

In order to recycle important rare metals (such as tantalum) in the print circuit boards of waste electronic equipment, devices must first be delaminated from board. The are then separated into each device type such capacitors, resistors, thermistors and so on. this study, effect orifices on spherical particles was clarified through numerical simulations airflow air–solid multiphase flow a vertical single-column pneumatic separator. Airflow velocity profiles particle trajectories were...

Persistent organic pollutants (POPs) are very difficult to degrade when present in the environment and finally accumulate human body. Therefore, it is essential develop efficient technologies for removal of POPs from polluted sediments. In this study, authors attempted evaluate potential hexachlorobenzene (HCB; a POP) by using ultrasonic irradiation its combination with other advanced chemical oxidation processes (AOPs) surfactant addition. The average ratios alone UV light were almost...

To recycle important rare metals (such as tantalum) from the printed circuit boards of waste electronic equipment, devices must first be delaminated boards. The are then separated into individual device types. For practical use separation process, authors previously developed a double-tube pneumatic separator. One features this equipment is introduction orifices in column; an air–solid multiphase flow simulation was conducted to clarify its effect. effects on floating characteristics and...
