Origin of mesosiderites as a natural consequence of planet formation

The mineral composition of mesosiderites is described and a theory of the origin and evolution of these meteorites is presented. It is suggested that the asteroid parent body of the mesosiderites also formed in the inner solar system, perhaps just within the orbit of Mars. As a result of close planetary encounters, some bodies that formed near Earth or Venus were gravitationally perturbed into non-circular orbits; a few such bodies passed through the mesosiderite region at high relative velocities, colliding with and destroying a few of the native asteroids. Olivine-rich silicate mantles shattered into small pieces, but the stronger metal cores remained as large fragments. Much of the debris remained in circular orbits and accreted to the basaltic regoliths of intact native asteroids at low relative velocities. The large core fragments that collided with the crust greatly enriched restricted regions of the surface in metal. These localized regions were the mesosiderite progenitors; they accounted for only about 1% of the surface area of the parent bodies

The British and Irish Ruling Class 1660-1945 Vol. 2

The book provides a comprehensive reference source for the governing class of Great Britain and Ireland from Oliver Cromwell to Winston Churchill, and offers a deep pool of data to support analysis of social, political, economic, and cultural history in the British Isles over the course of more than four centuries

Evaluation of the Effect of High Oil Corn Diets on Lamb Performance

The availability of corn varieties with higher oil content may offer an advantage as feed stuffs for various species and classes of livestock. Higher oil content increases the energy density in the feed stuff, potentially leading to improved performance and/or efficiency of gain. Additional benefits suggested are dust reduction, reduced energy for processing and improved palatability. Most research to date has been with swine and poultry diets. The object of these trials was to evaluate the effect of high oil corn com pared to normal corn in pre-weaning and post-weaning diets for lambs

Empowering and assisting natural human mobility: The simbiosis walker

This paper presents the complete development of the Simbiosis Smart Walker. The device is equipped with a set of sensor subsystems to acquire user-machine interaction forces and the temporal evolution of user's feet during gait. The authors present an adaptive filtering technique used for the identification and separation of different components found on the human-machine interaction forces. This technique allowed isolating the components related with the navigational commands and developing a Fuzzy logic controller to guide the device. The Smart Walker was clinically validated at the Spinal Cord Injury Hospital of Toledo - Spain, presenting great acceptability by spinal chord injury patients and clinical staf

A Comparison of Fall vs Spring Lambing Performance of Hampshire and Columbia Ewes (Progress Report)

Seasonality of lamb production continues to be a major hurdle for the sheep industry. The lack of a continuous supply of fresh lamb impacts both the processing and retail segments of the industry. The seasonal fluctuation in supply and quality results in sporadic buying patterns by consumers and ultimately less shelf space and therefore less product in the meat case. Often lamb cuts are not available in retail outlets or only on a seasonal basis making sustained consumption levels difficult. In many cases seasonal production also results in inefficient use of facilities, labor and management for the producer. This study was initiated to evaluate the effectiveness of selection for fall lambing in a population of purebred Hampshire and Columbia sheep

Fall Lambing Performance of Purebred Columbia and Hampshire Ewes

This study was initiated to evaluate the performance of purebred Columbia and Hampshire ewes selected for a September-October once a year lambing system in a effort to provide a more continuous supply of lambs to the market

Constrained Molecular Dynamics Simulations of Atomic Ground-States

Constrained molecular dynamics(CoMD) model, previously introduced for nuclear dynamics, has been extended to the atomic structure and collision calculations. Quantum effects corresponding to the Pauli and Heisenberg principle are enforced by constraints, in a parameter-free way. Our calculations for small atomic system, H, He, Li, Be, F reproduce the ground-state binding energies within 3%, compared with the results of quantum mechanical Hartree-Fock calculations.Comment: 3 pages, 2 figure

Radiative corrections for (e,e′p) reactions at GeV energies

A general framework for applying radiative corrections to (e,e′p) coincidence reactions at GeV energies is presented, with special emphasis to higher-order bremsstrahlung effects, radiation from the scattered hadron, and the validity of peaking approximations. The sensitivity to the assumptions made in practically applying radiative corrections to (e,e′p) data is extensively discussed. The general framework is tested against experimental data of the 1H(e,e′p) reaction at momentum transfer values larger than 1.0 (GeV/c)^2, where radiative processes become a dominant source of uncertainty. The formulas presented here can easily be modified for any other electron-induced coincidence reaction
