BACKGROUND Cobeljić et al. recently reported a numeric table method to provide precise rotational osteotomy which is a well established orthopaedic procedure. The numeric table requires four pages in length that is rather inconvenient during performing an osteotomy operation. METHODS We thus develop our own method by summarizing the data of the four-page table into a small ruler, which is eas...

The RSA-768 (270 decimal digits) was factored by Kleinjung et al. on December 12, 2009, while the RSA-704 (212 decimal digits) was factored by Bai et al. on July 2, 2012. The RSA-200 (663 bits) was factored by Bahr et al. on May 9, 2005, while he RSA-210 (696 bits) was factored by Propper on September 26, 2013. In this paper the author will discuss an estimation method to approach the lower/upp...

A prominent feature of comparative life histories in fish (and other indeterminate growers) is the approximate invariance across species of certain dimensionless numbers made up from reproductive and timing variables. The two best known are the age at maturity (alpha) divided by the average adult lifespan (E), and the proportion of a body mass given to reproduction per year (c) multiplied by E....

Humans prioritize the processing of threats over neutral stimuli; thus, not surprisingly, the presence of threats has been shown to alter performance on both perceptual and cognitive tasks. Yet whether the quantification process is disrupted in the presence of threat is unknown. In three experiments, we examined numerical estimation and discrimination abilities in adults in the context of threa...

BACKGROUND A comparison has been made of the development of mouse zygotes in either one-step or two-step culture systems. METHODS Embryo culture, blastocyst cell counts and embryo transfer were done. RESULTS No significant differences were observed in the proportions of blastocysts, rates of hatching, numbers of cells in the inner cell mass (ICM) and trophectoderm (TE) that developed in pro...

using haploid technique in breeding of sugar beet as an allogamous plant will facilitate breeding efforts. in this method,a pure line with a desirable genotype can be achieved by unfertilized ovule culture. therefore ovule culture was done from populations with numbers: 27621, 27624, 27626 and 27629. young flowering stems were collected and ovules were isolated from the flower buds after steril...
