    Notes: We investigate the problem of generation of maximally compact lattice chains which are useful in understanding folding of model proteins. The term, maximally compact chain, refers to a lattice self-avoiding walk that visits every lattice site. Generation of a representative sample of compact conformations is extremely difficult by conventional simulation methods such as static growth methods or dynamic Monte Carlo techniques. Growing a random walk is ineffective for generating long walks in a compact shape because a large number of walks are rejected due to overlap (attrition). In the interest of an unbiased sample, one needs to enumerate all possible compact conformations that are realizable or produce a representative sample, the former of which is intractable for long chains. In this paper a method is proposed for generation of compact chains on a lattice based on a mathematical programming approach. The method, which we refer to as the Hamiltonian path generation method, generates a random sample of lattice filling self-avoiding walks. A detailed description of a randomized generation algorithm is presented, which is effective for producing a static sample of compact lattice chains. There is a statistical evidence of fair generation of conformations from the conformational space using this scheme. This method generates a compact conformation on a 60×60×60 cubic lattice in forty minutes on a Sparc-2 workstation. © 1995 American Institute of Physics.

    Notes: This paper concerns configurational sampling methods for dense single chains for use in the study of low energy states of heteropolymers. The efficiency of current sampling techniques decreases with increasing density and breaks down completely when the volume fraction of the solvent approaches zero. Methods proposed for dense multichain systems are also ineffective for single chain conformational sampling. We propose a new elementary Monte Carlo move for dense single chains which generates new configurations by breaking and patching the chain. The effectiveness of this method is studied by testing its ability to identify global energy minima for maximally compact lattice chains. The algorithm is able to determine the ground state for a HP model protein of length 48 in around 37 000 steps. Computational results are presented for compact lattice chains of length up to 1000 on a 10×10×10 cubic lattice. © 1997 American Institute of Physics.

    Description / Table of Contents: Résumé On rend compte des études expérimentales sur le béton frais et le béton durci confectionnés avec des granulats de latérite qui sont abondants sur la côte sud-ouest de l'Inde. On a constaté que la proportion de 5/1 de latérite par rapport au sable de rivière donnait un béton d'ouvrabilité et de compactibilité satisfaisantes. On a confectionné plusieurs mélanges dont les rapports eau/ciment allaient de0,40 à0,60 et les rapports granulat/ciment de4 à6. On a étudié diverses propriétés, telles que l'ouvrabilité du béton jeune, les résistances en compression, flexion et traction, ainsi que le module d'élasticité du béton durci, sur cubes, cylindres et prismes. Les essais ont montré que l'ouvrabilité du béton à granulat de latérite, exprimée en résultats d'essais d'affaissement ou d'essais “vébé”, diminue avec l'augmentation du rapport granulat/eau. La résistance à la compression, qui va de 5 à 10 N/mm2 s'est révélée beaucoup plus faible que celle du béton à granulat de gravier ou de granit concassé, pour les proportions de granulat et les rapports eau/ciment considérés dans cette étude. La résistance en flexion du béton à granulat de latérite était de 20% de la résistance en compression, tandis que le rapport moyen de résistance en traction par fendage aux résistances en flexion et en compression était respectivement de 0,10 et de 0,47.
    Notes: Abstract The paper presents the results of tests conducted on fresh and hardened concrete using laterite as aggregate. Several mixes of laterite aggregate concrete were made with varying watercement and aggregate-cement ratios to study the properties like workability, compressive, flexural, tensile strength and Modulus of elasticity. The tests indicate that the workability decreases with increasing aggregate-water ratio. The compressive strength of laterite aggregate concrete is considerably lower than that of gravel or crushed granite aggregate concrete, while the average ratio of cylinder to cube strength compared favourably with that for normal aggregate concrete, for the range of aggregate and water-cement ratios covered in this investigation.
