Profession should resist further fragmentation

Should We Perform Semen Analysis, DNA Fragmentation, and Hypo-osmotic Swelling Tests together?

Semen analysis, sperm DNA fragmentation (SDF) and hypo-osmotic swelling test (HOST) are usually performed for the evaluation of sperm fertilizing ability. There are some debates over the necessity of SDF and HOST incorporation in male infertility work-up.Semen of 77 men was evaluated by SDF and HOST through three semen analyses. Sperm parameters were arranged into different categories: <5%, 5-1...

Health and fracking: should the medical profession be concerned?

The use of natural gas that is obtained from high-volume hydraulic fracturing (fracking) may reduce carbon emissions relative to the use of coal and have substantial economic benefits for South Africa. However, concerns have been raised regarding the health and environmental impacts. The drilling and fracking processes use hundreds of chemicals as well as silica sand. Additional elements are ei...

Quasi-Equilibrium Theory of Ionic Fragmentation: Further Considerations

A recent reformulation o f quasi-equilibrium theory is ex tended to several additional classes o f ionic decomposit ions . Formulae for calculating average translational and rotational energies o f the fragments are presented, and kinematic corrections to the formulas are introduced. I l lustrative calculations are compared with experiment, and the interesting possibil ity o f m a x i m a in ra...

Further study on YASS: steganography based on randomized embedding to resist blind steganalysis

We present further extensions of yet another steganographic scheme (YASS), a method based on embedding data in randomized locations so as to resist blind steganalysis. YASS is a JPEG steganographic technique that hides data in the discrete cosing transform (DCT) coefficients of randomly chosen image blocks. Continuing to focus on JPEG image steganography, we present, in this paper, a further st...
