This paper is an attempt to distinguish and discuss the Iranian (as distinct from the Turkish, Arabic and Islamic) elements in the present pattern of kinship and marriage practice in Persia in their historical context. This will entail also a discussion of what can be known of the pre-Islamic Iranian system. Disciplines Anthropology | Social and Behavioral Sciences This journal article is avail...

Conducting research in the acutely ill and injured is important to broaden the scientific foundation of nursing practice for the specialty. Given the nature of acute illness, challenges to the collection of self-report data are numerous, but they are not insurmountable. Attending to these challenges and planning for strategies to enhance the accuracy of data are important tasks for any investig...

Scientific investigation of mechanisms that determine lifespan can be divided into three general approaches. The first approach (the comparative method) began over a century ago comparing species differing greatly in maximum longevity and implicated a role for the speed of metabolism in determining the length of life [1]. The second approach commenced after the 1930s investigated the mechanisms...

BACKGROUND In a prospective study, 498 single faecal samples from children aged under 16 years attending an outpatient clinic in the Angkor Hospital for Children, northwest Cambodia, were examined for Cryptosporidium oocysts and Giardia cysts using microscopy and molecular assays. METHODOLOGY/PRINCIPAL FINDINGS Cryptosporidium oocysts were detected in 2.2% (11/498) of samples using microscopy...

Microtubules are intrinsically dynamic polymers, and their dynamics play a crucial role in mitotic spindle assembly, the mitotic checkpoint, and chromosome movement. We hypothesized that, in living cells, suppression of microtubule dynamics is responsible for the ability of taxol to inhibit mitotic progression and cell proliferation. Using quantitative fluorescence video microscopy, we examined...

Coulomb energy calculations for the lowest 0+ , T = 2 state in A = 16 nuclei allow tight constraints on the masses of the lowest 1/2+ , T = 3/2 state in 15O and 15F, and of the 0+ , T = 2 state in 16F.

The Pierre Auger Observatory, recently completed, has been operational since 2004. As a hybrid experiment, it allows for a wide range of measurements of UHECR-induced extensive air showers (EAS), including measurements of the EAS particle content on ground which is sensitive to high-energy hadronic interactions. We present the results of several independent measurements of the EAS muon content ...

We use a weak-coupling procedure and results of a shell-model calculation to compute the two-proton separation energy of 19Mg. Our result is at the upper end of the previous range, but 19Mg is still bound for single proton decay to 18Na. We also calculate the 2p decay width.
