Water is essential to the life of every living organism. The water used by consumer must be safe for preservation his health. objective this study was assess quality well in households city Korhogo. To do this, samples were taken from wells different households. Parameters such as pH, temperature, electrical conductivity and total dissolved solids measured at sampling sites. Nitrates ammonium d...

The topic of the paper is the study of germs of local holomorphisms f between Cn and Cn ′ such that f(M) ⊂ M ′ and df(T cM) = T cM ′ for M ⊂ Cn and M ′ ⊂ Cn generic real-analytic CR submanifolds of arbitrary codimensions. It is proved that for M minimal and M ′ finitely nondegenerate, such germs depend analytically on their jets. As a corollary, an analytic structure on the set of all germs of ...

The aim of this study was to determine the presence of third molar germs in patients with Class II/2 and Class III malocclusions. The study comprised 146 examinees from Zagreb and Istria. Examinees with Class II/2 malocclusions amounted to 77 and those with Class III 69. With regard to development of dentition the examinees were divided into two groups: Group I subjects with early mixed dentiti...

Many authors such as Morgenstern, ROse, Ahrens and N or b e r g have reported about the origin of the permanent tooth germs but the later development of this dentition has not been well illustrated. And there are few, if any, detailed studies concerning the position changes during development of permanent tooth germs. The present author previously (1957) postulated that deciduous tooth germs or...

The study of the geometry of non-isolated hypersurface singularities was begun by Siersma and his students ([11],[12],[9],[10]). The basic examples of such functions defining these singularities are the A(d) singularities and the D(q, p) singularities. The A(d) singularities, up to analytic equivalence, are the product of a Morse function and the zero map, while the simplest D(q, p) singularity...

By applying holomorphic motions, we prove that a parabolic germ is quasiconformal rigid, that is, any two topologically conjugate parabolic germs are quasiconformally conjugate and the conjugacy can be chosen to be more and more near conformal as long as we consider these germs defined on smaller and smaller neighborhoods. Before to prove this theorem, we use the idea of holomorphic motions to ...

In order to elucidate the role of parathyroid hormone-related peptide (PTHrP) in tooth development, we treated tooth germ explants of mouse molars with antisense phosphorothioate-oligodeoxynucleotide (ODN) against PTHrP. Antisense ODN-treatment of the explants resulted in the invasion of the tooth germs by bone. The number of tartrate-resistant acid phosphatase (TRAP)-positive cells around the ...
