IMPACT OF SIBSHIP SIZE, BIRTH ORDER, AND SEX COMPOSITION ON SCHOOL ENROLLMENT IN URBAN TURKEY [PDF]

open access: yes
This paper investigates the effects of sibship size, birth order and sibling sex composition on children’s school enrollment in urban Turkey. Moreover, we examine how the effects of these variables vary by household income and the gender of the children.

Ciliates in the plankton of the shallow zone of the Rybinsk Reservoir in spring: long-term changes in the community structure and the contribution of ciliates to the formation of the total biomass of the plankton community

open access: yesТрансформация экосистем
In spring (April 28‒May16, 2022) plankton of the shallow-water zone of the Rybinsk Reservoir, the biomass of large, predatory ciliates with symbiotic algae was 5‒8 times lower than that in the periods of late April‒May of 1971 and 1977, and their share ...

Matrix invariants of composite size

open access: yesJournal of Algebra, 1992
Let \(k\) be any field and \(n\geq 1\). Then \(\text{PGL}_ n(k)\) has a natural embedding in \(GL_{n^ 2} (k)\) as the group of automorphisms of \(M_ n(k)\), and one can consider the homogeneous space \(H(n)=GL_{n^ 2}(k)/ \text{PGL}_ n(k)\). This space \(H(n)\) has been proved to be rational for \(n=2,3\) and 4 by \textit{E. Formanek} [J.

Electrochemiluminescent Metallopolymer−Nanoparticle Composites: Nanoparticle Size Effects

open access: yesAnalytical Chemistry, 2011
Metallopolymer-gold nanocomposites have been synthesized in which the metal complex-Au nanoparticle (NP) mole ratio is systematically varied by mixing solutions of 4-(dimethylamino) pyridine protected gold nanoparticles and a [Ru(bpy)(2)PVP(10)](2+) metallopolymer; bpy is 2,2'-bipyridyl and PVP is poly-(4-vinylpyridine). The impact of changing the gold

Hinting at primary composition using asymmetries in time distributions [PDF]

open access: yes, 2005
Evidence of azimuthal asymmetries in the time structure and signal size have been found in non-vertical showers at the Pierre Auger Observatory. It has been previously shown that the asymmetry in time distributions offers a new possibility for the ...
