Energy dissipators, such as stilling basins, are usually required at the toe of stepped chutes to achieve adequate and safe operation spillway. Stepped chute hydraulics has been extensively studied in last several decades, however, only limited knowledge is available on basin performance below chutes. In particular, effect slope remains unknown, despite being a central design issue. Therefore, ...

Background: Most preclinical studies are carried out on mice. For internal dose assessment of a mouse, specific absorbed fraction (SAF) values play an important role. In most studies, SAF values are estimated using older standard human organ compositions and values for limited source target pairs.Objective: SAF values for monoenergetic photons of energies 15, 50, 100, 500, 1000 and 4000 keV...

Erosion at either dam or spillway foundations, destabilization in riverbanks, and damage the natural environment located downstream of dams spillways represent crucial elements to be taken into account risk assessment hydraulic structures. One main problems is related scouring that water flow may induce boundary spillways. This issue exacerbated case undersized stilling basins, i.e., when a sig...

HET/SAF-B was originally cloned as a nuclear matrix protein that bound to matrix attachment regions and as a transcriptional repressor of the small heat shock protein hsp27. In addition, we have found recently that HET/SAF-B is also a corepressor of estrogen receptor activity. Estrogen receptor has a very well-described role in breast cancer, and aberrant expression of nuclear matrix and heat s...

Serum amyloid A-activating factor-1 (SAF-1) is a zinc finger transcription factor that is activated by many mediators of inflammation including IL-1, IL-6, and bacterial LPS. However, the mechanism of activation is not fully understood. To identify possible activation partners for SAF-1, we used a yeast two-hybrid system that detected interaction between the catalytic subunit of cyclic AMP-depe...

Background: Hydraulic jump is considered the most appropriate option for designers to dissipate energy through stilling basins. Methods: Tests on a screen that produced submerged hydraulic were conducted of water passing beneath vertical gate. Various positions in sudden expanding basin investigated. In comparison no-screen case, effect downstream gate surface profile was also Results: The best...
