The animal care facilities act (1993)

"The 'Animal Care Facilities Act' passed by the state of Missouri, became effective Aug. 28, 1992. Under this act, a person who operates a shelter, kennel or breeding facility must be licensed. Each facility that houses or maintains dogs and cats, whether permanently for boarding or breeding, even if owned by the same individual, must be licensed. Organizations that provide for the adoption of dogs or cats also must arrange for these animals to be sterilized at the time of adoption or within a designated period of time soon after."--First page.Jeanette L.

Aerogel keystones: extraction of complete hypervelocity impact events from aerogel collectors

In January 2006, the Stardust mission will return the first samples from a solid solar-system body since Apollo, and the first samples of contemporary interstellar dust ever collected. Although sophisticated laboratory instruments exist for the analysis of Stardust samples, techniques for the recovery of particles and particle residues from aerogel collectors remain primitive. Here we describe our recent progress in developing techniques for extracting small volumes of aerogel, which we have called ``keystones,'' which completely contain particle impacts but minimize the damage to the surrounding aerogel collector. These keystones can be fixed to custom-designed micromachined silicon fixtures (so-called ``microforklifts''). In this configuration the samples are self-supporting, which can be advantageous in situations in which interference from a supporting substrate is undesirable. The keystones may also be extracted and placed onto a substrate without a fixture. We have also demonstrated the capability of homologously crushing these unmounted keystones for analysis techniques which demand flat samples.Comment: 17 pages, 11 figures, submitted to Meteoritics and Planetary Scienc

How To Tell What Political Processes People Want? Measuring Citizens’ Process Preferences in Surveys

This paper focuses on the operationalization of citizens’ preferences concerning how political decisions should be made. Recent research suggests that process preferences are a relevant predictor of the level of confidence citizens have in political institutions. However, there is no standardized scale for the measurement of such preferences. Hence, the aim of this paper is to present the development and validation of a multi-dimensional scale measuring citizens’ preferences concerning political decision-making processes. Based on existing research, a theoretical derived model with three dimensions and 16 indicators is tested. Those items were evaluated using confirmatory factor analysis (CFA) in structural equation modeling (SEM) and validated on another independent sample. The results indicate that process preferences consist of three factors: consensus-orientation, competition, and the efficiency of political decision-making processes. Moreover, further studies confirmed the cultural equivalence of the scale and its invariance as regards two different objects of assessment (parliament, government)

The effect of aqueous alteration and metamorphism in the survival of presolar silicate grains in chondrites

Relatively small amounts (typically between 2-200 parts per million) of presolar grains have been preserved in the matrices of chondritic meteorites. The measured abundances of the different types of grains are highly variable from one chondrite to another, but are higher in unequilibrated chondrites that have experienced little or no aqueous alteration and/or metamorphic heating than in processed meteorites. A general overview of the abundances measured in presolar grains (particularly the recently identified presolar silicates) contained in primitive chondrites is presented. Here we will focus on the most primitive chondrite groups, as typically the highest measured abundances of presolar grains occur in primitive chondrites that have experienced little thermal metamorphism. Looking at the most aqueously altered chondrite groups, we find a clear pattern of decreasing abundance of presolar silicate grains with increasing level of aqueous alteration. We conclude that the measured abundances of presolar grains in altered chondrites are strongly biased by their peculiar histories. Scales quantifying the intensity of aqueous alteration and shock metamorphism in chondrites could correlate with the content in presolar silicates. To do this it would be required to infer the degree of destruction or homogenization of presolar grains in the matrices of primitive meteorites. To get an unbiased picture of the relative abundance of presolar grains in the different regions of the protoplanetary disk where first meteorites consolidated, future dedicated studies of primitive meteorites, IDPs, and collected materials from sample-return missions (like e.g. the planned Marco Polo) are urgently required.Comment: 15 pages, 3 figures, published in PASA as part of the Proceedings of the 2008 Torino Conference "The Origin of the Elements Heavier than Iron

Infectious causes of infertility in sows (1993)

Any time a sow farrows prematurely, there is the fear that additional litters will be lost. An abortion rate of less than 2 percent is considered an acceptable level in most herds. Premature farrowing usually results from nutritional, genetic or environmental stresses, but the exact cause is often unknown. This publication addresses several infectious causes of infertility and abortion in sows along with some preventive measures

Herd management for disease prevention (1993)

Disease control is only one facet of a successful management program. Treatment of disease is not as effective or as economical as prevention. Many outbreaks of disease in swine herds can be avoided by using management practices that include strict sanitation and immunization programs

Controlling ultrafast currents by the non-linear photogalvanic effect

We theoretically investigate the effect of broken inversion symmetry on the generation and control of ultrafast currents in a transparent dielectric (SiO2) by strong femto-second optical laser pulses. Ab-initio simulations based on time-dependent density functional theory predict ultrafast DC currents that can be viewed as a non-linear photogalvanic effect. Most surprisingly, the direction of the current undergoes a sudden reversal above a critical threshold value of laser intensity I_c ~ 3.8*10^13 W/cm2. We trace this switching to the transition from non-linear polarization currents to the tunneling excitation regime. We demonstrate control of the ultrafast currents by the time delay between two laser pulses. We find the ultrafast current control by the non-linear photogalvanic effect to be remarkably robust and insensitive to laser-pulse shape and carrier-envelope phase
