By screening for mutations that perturb the invagination of the vulva of the Caenorhabditis elegans hermaphrodite, we have isolated 25 mutations that define eight genes. We have named these genes sqv-1 to sqv-8 (squashed vulva). All 25 mutations cause the same vulval defect, an apparent partial collapse of the vulval invagination and an elongation of the central vulval cells. Most sqv mutations...

the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

Photo 1: The inset shows a Dianthus pavonius flower infected with the Microbotryum. anthers of plant are covered in dark brown teliospores. background setup floral arrays that were used to test pollinator observations. Three triangular blocks set up 15 tubes two cut virgin flowers per tube. Within block, all one type: diseased, healthy hermaphrodite, or female. We observed number visits each bl...

in this paper, some results of the chebyshev type integral inequality for the pseudo-integral are proven. the obtained results, are related to the measure of a level set of the maximum and the sum of two non-negative integrable functions. finally, we applied our results  to the case of comonotone functions.

True hermaphrodite is one of the rarest variety of disorders of sexual differentiation (DSD) and represents only 5% cases of all. A 3-year-old child presented with left sided undescended testis and penoscrotal hypospadias. Chordee correction was performed 18 months back, elsewhere. At laparotomy Mullerian structures were present on left side. On right side testis was normally descended into the...

Sexually dimorphic plants provide an excellent opportunity for examining the differences in the extent of their defense against herbivores because they exhibit sex-related differences in reproductive investment. Such differences enable comparison of the sex with high reproduction expenses with the sex that expends less. The more costly sex is usually also better defended against herbivores. Gen...

In Cnidaria, a separation between soma and germline remains unclear. In this work, we studied the origin of germinal cells and determination of the sexual phenotype in Clytia hemisphaerica and Clytia sp. Colonies of C. Hemisphaerica were cultivated and the medusae liberated by each colony raised until maturity. Two hermaphrodite colonies were obtained, liberating male and female medusae. These ...
