    Safety Talk and Check to Prevent Pesticide Toxicity Among Farmer

    Full text link
    The problem at informal sector in particular for farmer when used the pesticides. In Sumber Mufakat village the farmers always use the pesticides without using the safety equipment and have direct contact with the pesticides exposure. The purpose of this research was to apply the safety talk and check method as prevention method to solve the pesticides toxicity that asses from safety and health of pesticide use behaviour. This preventive intervention research was using Participatory Action Research (PAR) design.The data collected by observation, quetionaire, and health check list. The population was all holticultura farmers in Sumber Mufakat village that divide in nine farmer's group. The sample collected by using proportional random sampling. The data will analyze by using qualitative descriptive. The result showed that the implication of safety talk and check method could prevent of pesticide exposure that present from safety and health of pesticides use behaviour. To support the action of safety talk method needed to develop one community that care about the farmers with government endorsement. The check method was very helpful the farmers to identify and predict their health. Both of it could be to cultivate the farmer in safety of pesticide used and early discovery of health symptom cause pesticide used

    A Semicoarsening Multigrid Algorithm for SIMD Machines

    A semicoarsening multigrid algorithm suitable for use on single instruction multiple data (SIMD) architectures has been implemented on the CM-2. The method performs well for strongly anisotropic problems and for problems with coefficients jumping by orders of magnitude across internal interfaces. The parallel efficiency of this method is analyzed, and its actual performance is compared with its performance on some other machines, both parallel and nonparallel

    Citation: McCullough, William Andrews. Bacteria- their relation to disease. Senior thesis, Kansas State Agricultural College, 1898.Morse Department of Special CollectionsIntroduction: He who has the privilege of laying out home grounds should consider the work as an art - for it demands quite as much in the way of aesthetic feeling, creative power and executive skill as does the art of sculpture and painting. This is the art which creates beautiful cornposition upon the surface of the ground. We are the painters with the earth as our canvas. It differs from the other arts, in that it uses the same materials as nature herself, as been said: - "This is an Art Which does mend Nature; change it rather but "The Art itself is nature". We see man producing many effects which, under favorable conditions nature herself might have produced without the aid of man. Home should stand for harmony, order, neatness and contentment. In order to have these we must study our surroundings and the materials we have to work with

    Reinventing spacetime on a dynamical hypersurface

    Full text link
    In braneworld models, Space-Time-Matter and other Kaluza-Klein theories, our spacetime is devised as a four-dimensional hypersurface {\it orthogonal} to the extra dimension in a five-dimensional bulk. We show that the FRW line element can be "reinvented" on a dynamical four-dimensional hypersurface, which is {\it not} orthogonal to the extra dimension, without any internal contradiction. This hypersurface is selected by the requirement of continuity of the metric and depends explicitly on the evolution of the extra dimension. The main difference between the "conventional" FRW, on an orthogonal hypersurface, and the new one is that the later contains higher-dimensional modifications to the regular matter density and pressure in 4D. We compare the evolution of the spacetime in these two interpretations. We find that a wealth of "new" physics can be derived from a five-dimensional metric if it is interpreted on a dynamical (non-orthogonal) 4D hypersurface. In particular, in the context of a well-known cosmological metric in 5D5D, we construct a FRW model which is consistent with the late accelerated expansion of the universe, while fitting simultaneously the observational data for the deceleration parameter. The model predicts an effective equation of state for the universe, which is consistent with observations.Comment: References added to the Introduction, and Abstract modified.

    Evolutionary Tracks of Trapped, Accreting Protoplanets: the Origin of the Observed Mass-Period Relation

    Full text link
    The large number of observed exoplanets (≳\gtrsim 700) provides important constraints on their origin as deduced from the mass-period diagram of planets. The most surprising features in the diagram are 1) the (apparent) pile up of gas giants at a period of ∼500\sim 500 days (∼1\sim1 AU) and 2) the so-called mass-period relation which indicates that planetary mass is an increasing function of orbital period. We construct the evolutionary tracks of growing planets at planet traps in evolving protoplanetary disks and show that they provide a good physical understanding of how these observational properties arise. The fundamental feature of our model is that inhomogeneities in protoplanetary disks give rise to multiple (up to 3) trapping sites for rapid (type I) planetary migration of planetary cores. The viscous evolution of disks results in the slow radial movement of the traps and their cores from large to small orbital periods. In our model, the slow inward motion of planet traps is coupled with the standard core accretion scenario for planetary growth. As planets grow, type II migration takes over. Planet growth and radial movement are ultimately stalled by the dispersal of gas disks via photoevaporation. Our model makes a number of important predictions: that distinct sub-populations of planets that reflect the properties of planet traps where they have grown result in the mass-period relation; that the presence of these sub-populations naturally explains a pile-up of planets at ∼1\sim 1 AU; and that evolutionary tracks from the ice line do put planets at short periods and fill an earlier claimed "planet desert" - sparse population of planets in the mass-semi-major axis diagram.Comment: 20 pages, 11 figures, 9 tables; accepted for publication in ApJ. No change in our conclusions while more discussion is added for supporting the importance of planet trap
