Summer aspect of phytoplankton communities in some Montenegrin lakes: Are there changes after more than two decades?

Summer aSpect of phytoplankton communitieS in Some montenegrin lakeS: are there changeS after more than two decadeS?

Qualitative and quantitative phytoplankton compositions of 10 Montenegrin lakes were investigated in the summer of 2007. The obtained results were compared with a previous study-period that was undertaken two decades ago. In the first period, diatoms numerically dominated the phytoplankton community in all studied lakes, while in the second period, the same was observed only in three of the ten...

There are no Barker arrays having more than two dimensions

Davis, Jedwab and Smith recently proved that there are no 2-dimensional Barker arrays except of size 2×2. We show that the existence of a (d+1)-dimensional Barker array implies the existence of a d-dimensional Barker array with the same number of ±1 elements. We deduce that there are no Barker arrays having more than two dimensions, as conjectured by Dymond in 1992.

Determinants of Quality of Life in the Caregivers of Iranian War Survivors with Bilateral Lower-Limb Amputation after More than Two Decades

Background: Providing care to a disable relative at home exposesthe caregiver to a potentially higher risk of physical and mentalproblems. We measured health-related quality of life (HRQOL) andits determinants among the caregivers of the Iranian survivors of theIran-Iraq war (1980–1988) with bilateral lower-limb amputation.Methods: Data were collected from 464 individuals comprisingwar-related ...

More than two decades of Apc modeling in rodents.

Mutation of tumor suppressor gene adenomatous polyposis coli (APC) is an initiating step in most colon cancers. This review summarizes Apc models in mice and rats, with particular concentration on those most recently developed, phenotypic variation among different models, and genotype/phenotype correlations.

When some are more equal than others.
