Introduction The main objective of the RataMine is to provide ap plication development interface to develop knowledge discovery applications on the top of large databases. Current database systems have been designed mainly to support business applications. The success of SQL capitalized on a small number of primitives which are sufficient to support a vast majority of ap plications today. Unfor...

N the medaka (Oryzius Zutipes) , an oviparous cyprinodont fish, the normal I sex-chromosome constitution is XX for female and XY for male (AIDA 1921). A series o€ our previous experiments have convincingly demonstrated that a heterotypic (atypical) sex hormone administered prior to and passing through the stage of gonadal sex differcntiation induces a complete reversal in sex differentiation. I...

The growth of aquaculture sector in Kenya has been anchored on farmed Nile tilapia Oreochromis niloticus. Different strains the species exist with unknown quality due to lack stock improvement programmes coupled by variations breeding and management practices different hatcheries. seeds supplied farmers have not exhibited good performance resilience changing climate. There is need validate fish...

Several new times of minimum light recorded with photoelectric means have been gathered for the early-type eccentric eclipsing binaries YY Sgr (P = 2. d63, e = 0.16), V523 Sgr (2. d32, 0.16), V1647 Sgr (3. d28, 0.41), V2283 Sgr (3. d47, 0.49) and V760 Sco (1. d73, 0.03). The O − C diagrams are analyzed using all reliable timings found in the literature and improved values for the elements of th...

In natural populations of platyfish, Xiphophorus maculatus, there are three sex chromosomes--W, X, and Y. Females may have one of three genotypes: WY, WX, or XX, and males may have either XY or YY. The W chromosome can be considered a modified X that blocks the male-determining function of the Y. The platyfish may represent an evolutionary stage at which female heterogamety arises through a sin...

A systematic analysis of nucleon-nucleon scattering amplitudes is available up to a laboratory energy $$3$$ GeV in case the $$pp$$ system and $$1.2$$ for $$pn$$ . At higher energies there only incomplete experimental information on elastic scattering, whereas data are very scarce. We apply spin-dependent Glauber theory calculate spin observables $$pd$$ at – $$50$$ GeV/c using literature paramet...
