Experimental evidence for the relaxation coupling of all longitudinal 7Li magnetization orders in the superionic conductor Li10GeP2S12

This contribution addresses the experimental proof of the relaxation coupling of the 7Li (I = 3/2) longitudinal magnetization orders in the solid-state electrolyte Li10GeP2S12 (LGPS). This effect was theoretically described by Korb and Petit in 1988 but has not yet been shown experimentally. In a 2D-T1/spin-alignment echo (SAE) experiment, the inverse Laplace transformation of the spectral component over two time dimensions revealed the asymmetric course of the spin-lattice relaxation following from the coupling of all longitudinal orders. These observations were supported by Multi-quantum-filter experiments and by simulations of the 2D-T1/SAE experiment with a lithium spin system. Since the asymmetric relaxation effects are directly dependent on the velocities and degrees of freedom of ion motion they could be used especially in fast Li-ion conductors as a separation tool for environments with different mobility processes

Phosphorylation site sequence of smooth muscle myosin light chain (Mr = 20 000)

AbstractThe amino terminal sequence of the myosin light chain (Mr = 20 000) isolated from chicken gizzards was found to be acetyl-Ser-Ser-Lys-Arg-Ala-Lys-Ala-Lys-Thr-Thr-Lys-Lys-Arg-Pro-Gln-Arg-Ala-Thr-Ser(P)-Asn-Val-Phe. This sequence assignment differs from that reported by Maita et al. [(1981) European J. Biochem. 117, 417] in the order of the tryptic peptides. The revised amino acid sequence exhibits greater homology with the phosphorylation site sequences of the regulatory light chains from cardiac and skeletal muscle. Moreover it is now apparent why synthetic peptides corresponding to the previously reported sequence were very poor substrates for the myosin light chain kinase

Development of a Regional Fence Model with Implications for Wildlife Management

Barbed and woven wire fence are ubiquitous features across much of western North America, yet their effects on wildlife have received less attention than those of other anthropogenic features. At this time, no geospatial fencing data is available at broad level scales; potentially making wildlife modeling of vagile species less accurate and conservation planning less reliable at various scales. Here, we model fence density across 13 counties in Montana’s Hi-Line region, based on publicly available GIS data and assumptions created from local, expert knowledge. The resulting fence location and density GIS layers are based on assumptions about where fence locations occur in association to different types of land tenure, land cover and roads. Locations of fences were collected via GPS along random 3.2 km long road transects (n = 738) to assess overall model accuracy. Using a confusion matrix to determine variation between field and modeled fence locations, the total accuracy of the model was 73% and Kappa was .40. Although we found inaccuracies associated with large parcels (>3 contiguous sections) of cultivated agriculture, our model is a promising step towards delineating fencing across the west. These general rules may be used and refined in the other areas based on the regional historical context. This new data may advance both wildlife research and management/mitigation activities. Using the relative density of fences across a region can prioritize conservation efforts at this broad scale. In addition, modeled fence locations provide useful and accurate information at a local scale

The Impact of Socioeconomic Factors on Selected Practices by Small Livestock Producers in Florida

Socioeconomic factors could affect the practices of small livestock producers who produce and sell locally or regionally. Yet, there is limited research on the issue in the Southeastern U.S., for example, Florida. Thus, this study assessed the impact of socioeconomic factors on practices of small livestock producers in Florida. The data were obtained from a sample of seventy producers from several counties in Florida, and were analyzed using descriptive statistics and logistic regression analysis. The results showed that a majority practiced rotational grazing; did not test soil regularly; had parasite problems; did not use veterinary services, and practiced record keeping. Further, the binary logistic regression analyses showed that selected socioeconomic factors had statistically significant effects on selected practices. For instance, gender had a statistically significant effect on soil testing; household income had a statistically significant effect on parasite problem; gender had a statistically significant effect on the use of veterinary services; and farming status, race/ethnicity, education, and household income had statistically significant effects on record keeping. The findings suggest that socioeconomic factors may be important in producers adopting practices.

An Analysis of the Characteristics and Practices of Selected Florida Small Livestock Producers: A Focus on Economics and Marketing

Issues regarding economics and marketing are of importance to small livestock producers, who produce and sell locally or regionally. This study, thus, assessed the characteristics and practices of selected Florida small livestock producers, emphasizing economics and marketing. Data were collected from a convenience sample of seventy small producers from several Florida counties, and were analyzed using descriptive statistics, including chi-square tests. The findings showed that there were many more: full-time producers; producers with at least a two-year/technical degree, and producers with at, least, a $40,000 annual household income. Most had been farming more than fifteen years, on at least 50 acres, and had small herds. Furthermore, very few of them made profits; they mainly sold animals live on-farm or at the auction/stockyard, and many of them kept records. Chi-square tests showed that gender, age, education, and household income had statistically significant effects on selected marketing characteristics. The findings suggest that educational programs that emphasize economic and marketing issues should be taken into consideration when designing programs for small producers in the study area.
