Caryological studies were carried out on ten species of the genus Suaeda belonging to 27 samples of different populations in Iran. Important chromosome features including numbers, lengths, centromere locations and caryotypes were studied. All the species have basic chromosome numbers of x=9. Chromosome counts of S. acuminata (C.A.Mey.) Moq. (2n=18), S. aegyptiaca (Hasselq.) Zoh., (2n=l8)...

Four new dicaffeoylquinic acid derivatives and two known 3-caffeoylquinic acid derivatives were isolated from methanol extracts using the aerial parts of Salicornia herbacea. The four new dicaffeoylquinic acid derivatives were established as 3-caffeoyl-5-dihydrocaffeoylquinic acid, 3-caffeoyl-5-dihydrocaffeoylquinic acid methyl ester, 3-caffeoyl-4-dihydrocaffeoylquinic acid methyl ester, and 3,...

We investigate the effects of the institutional settings of the US health care system on individuals' life-cycle medical expenditures. Health is a form of general human capital; labor turnover and labor-market frictions prevent an employer-employee pair from capturing the entire surplus from investment in an employee’s health. Thus, the pair underinvests in health during working years, thereby ...

This work presents preliminary results about the use of TerraSAR-X imagery for mapping intertidal habitats (oyster parks, seagrass meadows of Zostera noltii, sediments) along coastal lagoons (Arcachon lagoon, France). The combination of SAR and optical data appears to be useful to improve the discrimination of the various sediment and vegetation covers into classification schemes. Unlike optica...

In the last talk of this conference, Joanne Walters-Wayland will discuss a continuum of minimizable properties of sublocales of a (completely regular) locale. By that is meant a property P such that above any dense sublocale S of a locale L there is a least sublocale having property P. Such properties induce a contraction of the lattice of prenuclei of the frame, i.e., an order-preserving map w...
