LABCON - Laboratory Job Control program

Computer program LABCON controls the budget system in a component test laboratory whose workload is made up from many individual budget allocations. A common denominator is applied to an incoming job, to which all effort is charged and accounted for

Hadamard inverses, square roots and products of almost semidefinite matrices

Let A = (aij) be an n × n symmetric matrix with all positive entries and just one positive eigenvalue. A◦(−1) = ( 1) is positive semidefinite. aij Bapat proved then that the Hadamard inverse of A, given by We show that if moreover A is invertible then A ◦(−1) is positive definite. We use this result to obtain a simple proof that with the same hypotheses on A, except that all the diagonal entries of A are zero, the Hadamard squar

Sport Commitment and Purchase Intentions of Intercollegiate Boxing Coaches and Participants

The current study analyzed the sport commitment and purchase intentions of club level intercollegiate boxers and coaches. Participants at United States Intercollegiate Boxing Association ( USIBA) member institutions ( N = 155) completed an online survey answering questions regarding their sport commitment and future equipment purchase intentions. Multivariate analysis discovered significant sport commitment differences among boxers and coaches, Wilk\u27s Lambda =.838, F ( 7, 125) = 3.46,

Letter, Vinnie Ream to Mrs. Nealy, January 26, 1870

This handwritten letter, dated January 26, 1870, is written from Vinnie Reams to Mrs. Nealy. The letter mentions the Lincoln statue that Reams is sculpting and his pleasure at the model of it being so highly regarded by his friends and neighbors. The letter goes on to describe some of his other artistic endeavors and invites her to write to him often. A note identifying Vinne Reams as a sculptor is written in pencil along the left edge of the firs page of the letter. A typed transcript of the letter is included.https://scholarsjunction.msstate.edu/fvw-manuscripts-hoxie/1000/thumbnail.jp

Pathways of genetic adaptation: multistep origin of mutants under selection without induced mutagenesis in Salmonella enterica.

In several bacterial systems, mutant cell populations plated on growth-restricting medium give rise to revertant colonies that accumulate over several days. One model suggests that nongrowing parent cells mutagenize their own genome and thereby create beneficial mutations (stress-induced mutagenesis). By this model, the first-order induction of new mutations in a nongrowing parent cell population leads to the delayed accumulation of visible colonies. In an alternative model (selection only), selective conditions allow preexisting small-effect mutants to initiate clones that grow and give rise to faster-growing mutants. By the selection-only model, the delay in appearance of revertant colonies reflects (1) the time required for initial clones to reach a size sufficient to allow the second mutation plus (2) the time required for growth of the improved subclone. We previously characterized a system in which revertant colonies accumulate slowly and contain cells with two mutations, one formed before plating and one after. This left open the question of whether mutation rates increase under selection. Here we measure the unselected formation rate and the growth contribution of each mutant type. When these parameters are used in a graphic model of revertant colony development, they demonstrate that no increase in mutation rate is required to explain the number and delayed appearance of two of the revertant types

Solid-state N.M.R. studies of platinum and tin compounds

High-resolution solid-state N.M.R. studies of dilute spins are now possible using cross-polarisation and MAS techniques. A systematic evaluation has been undertaken to determine their applicability to spin-½ metal nuclei, in particular (^195)Pt and (^119)Sn. In addition, an extensive (^13)C and (^31)p solid-state N.M.R. study has been carried out on a selection of Pt(II) complexes, supplying information on isotropic (scalar) coupling constants and shielding anisotropy. The majority of (^119)Sn and (^195)Pt spectra exhibit a multitude of spinning sidebands due to the large shielding anisotropy present. The tin systems under study have been of type R(_3)SnX (where R = Alkyl, phenyl and X = F, OH, CI); some are shown to be polymeric in the solid-state with penta-coordinate tin present. Where possible, correlations with X-ray crystallographic data and solution-state N.M.R. studies are giving. The interactions present in Pt(IV) compounds containing directly bonded quadrupolar nuclei have been studied and imply motional activity present in the solid- state. A more comprehensive study of these effects is given for two tin systems (Ph(_3)SnCl and (NH(_4))(_2)SnCl(_6)), whereby observed splittings can be accounted for by a combination of (^119)Sn-Cl dipolar and scalar coupling. The interplay of tensor properties between spin-½ nuclei, namely (1) dipolar coupling, (11) indirect (scalar) coupling and (111) shielding anisotropy is explored in solid-state (^195)pt-(^31)p and (^119)sn-(^19)f systems. The theory for such tensorial interplay is given for an AX(_2) system
