Fatigue testing a plurality of test specimens and method

Described is a fatigue testing apparatus for simultaneously subjecting a plurality of material test specimens to cyclical tension loading to determine the fatigue strength of the material. The fatigue testing apparatus includes a pulling head having cylinders defined therein which carry reciprocating pistons. The reciprocation of the pistons is determined by cyclical supplies of pressurized fluid to the cylinders. Piston rods extend from the pistons through the pulling head and are attachable to one end of the test specimens, the other end of the test specimens being attachable to a fixed base, causing test specimens attached between the piston rods and the base to be subjected to cyclical tension loading. Because all the cylinders share a common pressurized fluid supply, the breaking of a test specimen does not substantially affect the pressure of the fluid supplied to the other cylinders nor the tension applied to the other test specimens

Analyzing the Implementation of Nutrient Management Plans by Farmers: Implications for Extension Education

We conducted case studies on four Connecticut dairy farms to evaluate how well farmers implemented their nutrient management plans (NMPs). Our findings can help Extension educators develop programs to improve NMPs and NMP adoption by farmers. We identified three educational topic areas that would likely increase NMP understanding and acceptance: (a) soil testing protocol, results interpretation, and nutrient recommendations; (b) manure fertilizer-equivalent value, proper application, and effective distribution; and (c) costs and benefits of substituting on-farm manure for purchased commercial fertilizer. A new adaptive nutrient management program presents a timely opportunity for cost-effective and collaborative on-farm education efforts by Extension and the Natural Resources Conservation Service

How primary care can contribute to good mental health in adults.

The need for support for good mental health is enormous. General support for good mental health is needed for 100% of the population, and at all stages of life, from early childhood to end of life. Focused support is needed for the 17.6% of adults who have a mental disorder at any time, including those who also have a mental health problem amongst the 30% who report having a long-term condition of some kind. All sectors of society and all parts of the NHS need to play their part. Primary care cannot do this on its own. This paper describes how primary care practitioners can help stimulate such a grand alliance for health, by operating at four different levels - as individual practitioners, as organisations, as geographic clusters of organisations and as policy-makers

Influence of Time of Application of Nitrogen Fertilizer on Corn Yields

Soil moisture conditions can have a large effect on crop responses to nitrogen fertilization. Kentucky\u27s usual climatic pattern of periods of heavy rainfall and relatively warm temperatures during the winter and spring seasons influences expected yield responses of corn to applied nitrogen. If nitrogen fertilizer is applied in late winter or early spring, some of it may be lost before the plants have made sufficient growth to take up appreciable quantities. The amount of loss that might be expected will be influenced by the amount of rainfall, temperature, amount of organic matter and drainage of the soil
