How cell fate decisions of stem and progenitor cells are regulated by their microenvironment or niche is a central question in stem cell and regenerative biology. Although functional analysis of hair follicle epithelial stem cells by gene targeting is well established, the molecular and genetic characterization of the dermal counterpart during embryonic morphogenesis has been lacking because of...

The emergence of technology mediated learning has translated the primitive mode of learning into an enhanced technological mode where learning is not restricted to a particular geographical location, space, time etc. There is more on a new wave of learning strategies and approaches to motivate online learners to engage in learning process tailored through learning paths that lead to successful ...

In this paper, Exp-function and (G′/G)expansion methods are presented to derive traveling wave solutions for a class of nonlinear space-time fractional differential equations. As a results, some new exact traveling wave solutions are obtained.

Oestrous synchronization involves synchronization of ovarian follicular turnover, new wave emergence, and finally induction of ovulation. The final step can be synchronized by the parenteral administration of either GnRH or oestradiol benzoate. This study investigated corpus luteum and follicular emergence after ovulation had been induced by the administration of either GnRH or oestradiol benzo...

Over recent years the electronics manufacturing industry has seen a shift away from wave soldering towards reflow soldering [1]. However, although wave soldering is indeed mature (first used during the 1950’s [eg 2]), there is still significant activity with novel process development to match [3]. This paper concerns a new type of noclean liquid flux for wave soldering that is based on water [4...

The physical conditions in the inner parsec of accretion disks believed to orbit the central black holes in active galactic nuclei can be probed by imaging the absorption (by ionized gas in the disk) of background emission from a radio counterjet. We report high angular resolution VLBI observations of the nearby (∼ 40 Mpc) radio galaxy NGC 4261 that confirm free-free absorption of radio emissio...

cconcerning the emer gence of substantial changes in major cities within the past two decades and its relationship to a set of ideas which envisage the emergence of a new urban era, this article will try to examine the different aspects of the new urban policies as a necessary response to a new national and international economy. cconcerning the emer gence of substantial changes in major cities...

in this work, we successfully construct the new exact traveling wave solutions ofthe generalized sinh–gordon equation by new application of the homogeneousbalance method. the idea introduced in this paper can be applied to othernonlinear evolution equations.
