BACKGROUND Routine administration of supplemental oxygen to parturients undergoing Caesarean section under spinal anaesthesia has been criticised in recent times. OBJECTIVES To assess the need for routine supplementary oxygen in healthy women undergoing Caesarean section under spinal anaesthesia in resource challenged setting and establish the efficacy of administration of oxygen at 4L/min. ...

Results of a new analysis of the K+K− photoproduction at two photon energies Eγ = 4 GeV and 5.65 GeV with a particular emphasis on the S-wave production are presented. We show that the proper treatment of all the helicity components of the Sand P -waves enables one to eliminate the reported discrepancies in the extraction of the Swave photoproduction cross section from experimental data.

Let 1 < p ̸= 2 < ∞, ε > 0 and let T : lp(l2) into → Lp[0, 1] be an isomorphism Then there is a subspace Y ⊂ lp(l2), (1 + ε)-isomorphic to lp(l2), such that: T|Y is an (1+ ε)-isomorphism and T (Y ) is Kp-complemented in Lp [0, 1], with Kp depending only on p. Moreover, Kp ≤ (1 + ε)γp if p > 2 and Kp ≤ (1 + ε)γp/(p−1) if 1 < p < 2, where γr is the Lr norm of a standard Gaussian variable.

To describe the log-likelihood computation in our model, let us consider a two scale pyramid for the moment. Given a (vectorized) j × j image I , denote by l = d(I) the coarsened image, and h = I − u(d(I)) to be the high pass. In this section, to simplify the computations, we use a slightly different u operator than the one used to generate the images displayed in Figure 3 of the paper. Namely,...

Using a recent result of Batson, Spielman and Srivastava, We obtain a tight estimate on the dimension of lp , p an even integer, needed to almost isometrically contain all k-dimensional subspaces of Lp. In a recent paper [BSS] Batson, Spielman and Srivastava introduced a new method for sparsification of graphs which already proved to have functional analytic applications. Here we bring one more...

Let E → C be an elliptic surface, defined over a number field k, let P : C → E be a section, and let l be a rational prime. We bound the number of points of low algebraic degree in the l-division hull of P at the fibre Et. Specifically, for t ∈ C(k) with [k(t) : k] ≤ B1 such that Et is non-singular, we obtain a bound on the number of Q ∈ Et(k) such that [k(Q) : k] ≤ B2, and such that lQ = Pt, f...

Abercrombie's formula: P = A X M/(L + M) (P = average number of nuclear points per section; A = crude count; M = thickness of section; L = particle size. Explanation: "Ideal points" would be found in only one tissue section each. Particles of finite size will be cut on...

Abstract A measurement of the Z production cross-section in collisions at Large Hadron-electron Collider (LHeC) is presented for comparison to that International Linear (ILC). The total depends strongly on polarization initial and final beams electron beam energy E_{e} ; proton was set E_{p} = 7 TeV. results show \rightarrow l^{-}l^{+}e^{-} LHeC much larger than ILC.
