    Let MM be a smooth compact surface, orientable or not, with boundary or without it, PP either the real line R1R^1 or the circle S1S^1, and Diff(M)Diff(M) the group of diffeomorphisms of MM acting on C∞(M,P)C^{\infty}(M,P) by the rule h⋅f↦f∘h−1h\cdot f\mapsto f \circ h^{-1}, where h∈Diff(M)h\in Diff(M) and f∈C∞(M,P)f \in C^{\infty}(M,P). Let f:M→Pf:M \to P be a Morse function and O(f)O(f) be the orbit of ff under this action. We prove that πkO(f)=πkM\pi_k O(f)=\pi_k M for k≥3k\geq 3, and π2O(f)=0\pi_2 O(f)=0 except for few cases. In particular, O(f)O(f) is aspherical, provided so is MM. Moreover, π1O(f)\pi_1 O(f) is an extension of a finitely generated free abelian group with a (finite) subgroup of the group of automorphisms of the Reeb graph of ff. We also give a complete proof of the fact that the orbit O(f)O(f) is tame Frechet submanifold of C∞(M,P)C^{\infty}(M,P) of finite codimension, and that the projection Diff(M)→O(f)Diff(M) \to O(f) is a principal locally trivial S(f)S(f)-fibration.Comment: 49 pages, 8 figures. This version includes the proof of the fact that the orbits of a finite codimension of tame action of tame Lie group on tame Frechet manifold is a tame Frechet manifold itsel

    B553: Consumer Packages for Maine Mcintosh Apples

    Get PDF
    Three kinds of consumer packages for apples were developed for testing in the 1955-56 marketing season. In developing these packages, the authors modified the jumble-pack, polyethylene package in a way that would protect the fruit from most of the bruising and still maintain almost complete visibility of the fruit. One consumer package developed was a long narrow polyethylene bag, another was a polyethylene bag with a divider insert, and the third package had a cell partition placed in a similar plastic bag. All three packages were well accepted by consumers in the Portland market.https://digitalcommons.library.umaine.edu/aes_bulletin/1085/thumbnail.jp

    New empirical fits to the proton electromagnetic form factors

    Get PDF
    Recent measurements of the ratio of the elastic electromagnetic form factors of the proton, G_Ep/G_Mp, using the polarization transfer technique at Jefferson Lab show that this ratio decreases dramatically with increasing Q^2, in contradiction to previous measurements using the Rosenbluth separation technique. Using this new high quality data as a constraint, we have reanalyzed most of the world e-p elastic cross section data. In this paper, we present a new empirical fit to the reanalyzed data for the proton elastic magnetic form factor in the region 0 < Q^2 < 30 GeV^2. As well, we present an empirical fit to the proton electromagnetic form factor ratio, G_Ep/G_Mp, which is valid in the region 0.1 < Q^2 < 6 GeV^2
