OBJECTIVE To estimate the role of human milk n-6 and n-3 polyunsaturated fatty acids (PUFA) in term infant growth in two African urban populations. DESIGN Observational study. Weight gains at 5 months of age and dietary habits were compared between Congolese infants (n=102) and Burkinabè infants (n=101). Socio-economic status and anthropometry of the mothers were also recorded. SETTING One ...

An n-particle 3-dimensional Wigner quantum oscillator model is constructed explicitly. It is non-canonical in that the usual coordinate and linear momentum commutation relations are abandoned in favour of Wigner’s suggestion that Hamilton’s equations and the Heisenberg equations are identical as operator equations. The construction is based on the use of Fock states corresponding to a family of...

We use the grid consisting of bits of 3n to motivate the definition of 2-adic numbers. Specifically, we exhibit diagonal stripes in the bits of 32 n , which turn out to be the first in an infinite sequence of such structures. Our observations are explained by a 2-adic power series, providing some regularity among the disorder in the bits of powers of 3. Generally, the base-p representation of k...

1 I n t r o d u c t i o n The problem of selecting the element with a given rank in a set of n elements was shown to be solvable in ~9(n) time by Blum et al. in 1973 [2]. This was a surprise to the research community since it was believed that the general selection problem was as difficult as sorting. They showed that the number of comparisons needed for the problem of median finding is at most...

The effects of cigarette smoking on n-3 essential FA metabolism were studied in male and female subjects by fitting the concentration-time curves of the d(5)-labeled plasma fatty acids (FAs) originating from a dose of d(5)-18:3n-3 to a compartmental model of n-3 FA metabolism. For 3 weeks, female (smokers, n = 5; nonsmokers, n = 5) and male (smokers, n = 5; nonsmokers, n = 5) subjects subsisted...

The visibility representation (VR for short) is a classical representation of plane graphs. It has various applications and has been extensively studied. A main focus of the study is to minimize the size of the VR. It is known that there exists a plane graph G with n vertices where any VR of G requires a grid of size at least 2 3n × ( 4 3n − 3) (width × height). For upper bounds, it is known th...

The effects of an increasing proportion of crushed linseed (CL) in combination with varying forage type (grass or corn silage) and forage to concentrate ratio (F:C), and their interactions on milk fatty acid (FA) profile of high-producing dairy cows was studied using a 3-factor Box-Behnken design. Sixteen Holstein and 20 Swedish Red cows were blocked according to breed, parity, and milk yield, ...

We present two noncommutative algebras over a field of characteristic zero that each possesses family actions by cyclic groups order $2n$, represented in $2 \times 2$ matrices, requiring generators degree $3n$.
