1. Lactose, sucrose or maltose were administered to rats by gavage together with 32PO4, and blood 32P was determined. 2. PO4 uptake into blood was increased only when lactose and PO4 were administered into the gut. 3. Weaned male rats were fed on a control diet or a diet containing 30, 60 or 120 g lactose/kg. After a 5 d period of adaptation, a 6 d P balance was carried out. After a further 24 ...

Pyridoxal-PO* binds to pepsinogen in a reaction in which the stoichiometry is highly dependent on the conformation of the protein. When pepsinogen is in its native conformation, pyridoxal-PO4 forms Schiff bases with the (r-NH2 group of Leul and the e-NH2 group of LysZS8. When the protein is mildly denatured and assumes a more extended conformation, pyridoxal-PO4 can react with the t-NH2 groups ...

According to the well-known Doob’s lemma, the expected number of crossings of every fixed interval (a,b) by trajectories of a bounded martingale (Xn) is finite on the infinite time interval. For such a random sequence (r.s.) with an extra condition that Xn takes no more than N, N < ∞, values at each moment n ≥ 1, this result was refined in Sonin (1987) by proving that inside any interval (a,b) ...

Absorptive corrections to the one pion exchange and measurability of the small-x pion structure function at HERA Abstract We compare the absorptive corrections to the one pion exchange in pp → Xn and ep → e ′ Xn reactions. It is shown that the absorption is stronger in the case of pp collision. The difference in strength of the absorption for the pp → Xn and ep → e ′ Xn reactions breaks the fac...

In this paper, we consider the nonlinear difference equation xn 1 f xn−l 1, xn−2k 1 , n 0, 1, . . . , where k, l ∈ {1, 2, . . . } with 2k / l and gcd 2k, l 1 and the initial values x−α, x−α 1, . . . , x0 ∈ 0, ∞ with α max{l − 1, 2k − 1}. We give sufficient conditions under which every positive solution of this equation converges to a not necessarily prime 2-periodic solution, which extends and ...

A redesign method for discretizing a continuous-time controller is proposed. The resulting hybrid control system, for example with continuous-time plant and discrete-time controller, is stable, and performance including the system's inter-sampling behaviour can be optimized by approximating some chosen reference transfer function of the continuous-time control system. In order to obtain a tract...

the unitary cayley graph xn has vertex set zn = {0, 1,…, n-1} and vertices u and v areadjacent, if gcd(uv, n) = 1. in [a. ilić, the energy of unitary cayley graphs, linear algebraappl. 431 (2009) 1881–1889], the energy of unitary cayley graphs is computed. in this paperthe wiener and hyperwiener index of xn is computed.

BACKGROUND The interaction between Ca-HAP and Pb(2+) solution can result in the formation of a hydroxyapatite-hydroxypyromorphite solid solution [(PbxCa1-x)5(PO4)3(OH)], which can greatly affect the transport and distribution of toxic Pb in water, rock and soil. Therefore, it's necessary to know the physicochemical properties of (PbxCa1-x)5(PO4)3(OH), predominantly its thermodynamic solubility ...

Studies investigating the effect of increasing CO2 levels on the phosphorus cycle in natural waters are lacking although phosphorus often controls phytoplankton development in many aquatic systems. The aim of our study was to analyse effects of elevated CO2 levels on phosphorus pool sizes and uptake. The phosphorus dynamic was followed in a CO2-manipulation mesocosm experiment in the Storfjärde...
