    Determination of Insect Infestation in Food: A Semiautomated Calorimetric Analysis for Uric Acid with Immobilized Uricase (1981)

    Notes: A semiautomated differential calorimetric procedure for the determination of uric acid is reported. Samples are treated with hydrochloric acid, incubated at 55–60°C in a water bath, and neutralized with sodium hydroxide. Uric acid is extracted with sodium acetate and is determined with phosphotungstic acid as the color reagent. Uric acid is destroyed with uricase, and the calorimetric analysis is repeated for a blank measurement. The reaction specificity of uricase and its immobilization in a nylon coil contribute to the reliability of the method, which permits analysis of 30 samples/hr. Recovery studies and analyses of actual samples show that uric acid can serve as a chemical index of insect infestation in a variety of foods. The sensitivity of the method is approximately 5 μg uric acid/g of sample and is adequate to ascertain objectionable levels of stored product insect excreta contamination in food products.

    Notes: Inactivation kinetics of Clostridium perfringens strains NCTC 8238 and NCTC 8798 vegetative cells were evaluated in autoclaved ground beef after growth at constant (37, 41, 45, or 49°C) or linearly rising temperatures (4.0, 6.0, or 7.5 C°/hr) representative of long-time, low-temperature (LTLT) cooking. Inactivation temperatures of 55, 57, 59, 60, and 61°C were used. D values and z values were determined. For strain NCTC 8798 cells grown at 45°C, the average D59°C was 7.2 min and the zD was 3.8 C°. Both strains exhibited greater heat resistance after growth at higher constant temperatures. Also, NCTC 8798 was more heat resistant than NCTC 8238. With linearly rising temperature, terminal growth temperatures appeared dominant in resistance to inactivation. These data will permit predictions of growth and survival of C. perfringens during LTLT cooking of beef roasts.

    Mapping Police Organizational Change: From a Mechanistic Toward an Organic Model (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Criminology 20 (1982), S. 0 
    Details
    ISSN: 1745-9125

    Topics: Law
    Notes: Community police organizations have been the focus of substantial research since the 1960s. Recommendations from this research have frequently suggested some degree of reform. This reform effort has been directed in part at the oragnizational design of police departments, emphasizing movement away from a mechanistic to more of an organic approach. This article describes mechanistic and organic model constructs and relates them to both continuum and matrix change perspectives and a change problem-intervention strategy typology. The matrix and typology are used to “map” the change process associated with team policing, which is one example of attempts to make police organizations more organic.

    CREATING MEANINGFUL STAKEHOLDER INVOLVEMENT IN WATERSHED PLANNING IN PIERCE COUNTY, WASHINGTON (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 38 (2002), S. 0

    Notes: : Since 1989, the government of Pierce County, Washington, has prepared four watershed action plans. The watersheds cover almost 800,000 acres and include about 600,000 residents and diverse land uses, from the city of Tacoma to Mount Rainier National Park. The primary purpose of these plans was to address water quality impacts from nonpoint sources of pollution and to protect beneficial uses of water. Pierce County has experienced problems such as shellfish bed closures and the Federal Clean Water Act Section 303(d) listing of local water bodies as a result of declining water quality. Pierce County achieved improvements by engaging diverse groups of stakeholders in generating solutions to nonpoint sources of water pollution through our watershed planning process. Using participatory methods borrowed from private industry, Pierce County was able to reach consensus, build trust, maximize participation, facilitate learning, encourage creativity, develop partnerships, shorten time frames for the planning processes, and increase the level of commitment participants had to implementing the plans. As a result, the earliest plans have a high rate of voluntary implementation. This indicates that the process and methodology used to develop watershed plans has a significant, if not critical, impact on their success.

    Differential regulation by exercise of BDNF and NT-3 in rat spinal cord and skeletal muscle (2001)
    Oxford, UK : Blackwell Science Ltd
    European journal of neuroscience 13 (2001), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: We have investigated the impact of neuromuscular activity on the expression of neurotrophins in the lumbar spinal cord region and innervating skeletal muscle of adult rats. Rats were exercised on a treadmill for 1 day or 5 consecutive days and euthanized at 0, 2 or 6 h after the last bout of exercise. By Day 1, there was no clear evidence of an increase in brain-derived neurotrophic factor (BDNF) mRNA in the spinal cord or the soleus muscle. By Day 5, there was a significant increase in BDNF mRNA in the spinal cord at 2 h post-training, and the soleus muscle showed a robust increase between 0 and 6 h post-training. Immunoassays showed significant increases in BDNF protein in the soleus muscle by training Day 5. Immunohistochemical analyses showed elevated BDNF levels in motoneuron cell bodies and axons in the ventral horn. Neurotrophin-3 (NT-3) mRNA was measured to determine whether selected neurotrophins respond with a selective pattern of induction to neuromuscular activity. In the spinal cord, there was a progressive post-training decrease in NT-3 mRNA following a single bout of training, while there was a significant increase in NT-3 mRNA at 2 h post-training by Day 5. The soleus muscle showed a progressive increase in NT-3 mRNA by Days 1 and 5 following training. These results show that neuromuscular activity has specific effects on the BDNF and NT-3 systems, and that repetitive exercise affects the magnitude and stability of these responses.

    Effect of tillage, cover crop and crop rotation on the composition of weed flora in a sandy soil (2002)

    Notes: The development of integrated weed management strategies requires knowledge of mechanisms that influence compositional changes in weed flora. A 9-year study was initiated in 1988 at Delhi, Canada, on a loamy sand soil to evaluate the effect of tillage systems [conventional (CT) and no-till (NT)] and cover crops (only in NT) on weed density, species composition and associations, and crop yield in a winter wheat (Triticum aestivum L.)/bean/winter wheat rotation. Three bean types: soyabean (Glycine max L. Merr.), white bean (Phaseolus vulgaris L.) and kidney bean (P. vulgaris L.) were included. The NT system included variations: rye (Secale cereale L.) or maize (Zea mays L.) cover crop, volunteer wheat disked after harvest and wheat stubble. Data were collected in 1994, 1995 and 1996. Tillage systems, cover crops and crop type had differential effects on weed densities, species composition and associations. Weed densities were not affected by tillage or cover crops in wheat but, in the beans, densities were greater in the CT than in the NT systems. Various associations of weed species with tillage system, cover crop and crop type were observed. Crop yields were not affected by tillage type or cover crop, except that soyabean yields were highest in plots with cover crops.
