The economics of farm accidents and safety in New Zealand agriculture

This report presents an economic analysis of farm accidents in New Zealand. Presently, the social costs of farm accidents are not well understood: their monetary importance to the farmer, hence the nation,has thus far not been quantified in a way meaningful to safety policy makers. Information about the relative magnitude of social costs resulting from accidents on farms is necessary to establish the potential social benefits attributable to safety. Such information is required if safety expenditures are to be rationally allocated to priority needs

Experimental Design for the LATOR Mission

This paper discusses experimental design for the Laser Astrometric Test Of Relativity (LATOR) mission. LATOR is designed to reach unprecedented accuracy of 1 part in 10^8 in measuring the curvature of the solar gravitational field as given by the value of the key Eddington post-Newtonian parameter \gamma. This mission will demonstrate the accuracy needed to measure effects of the next post-Newtonian order (~G^2) of light deflection resulting from gravity's intrinsic non-linearity. LATOR will provide the first precise measurement of the solar quadrupole moment parameter, J2, and will improve determination of a variety of relativistic effects including Lense-Thirring precession. The mission will benefit from the recent progress in the optical communication technologies -- the immediate and natural step above the standard radio-metric techniques. The key element of LATOR is a geometric redundancy provided by the laser ranging and long-baseline optical interferometry. We discuss the mission and optical designs, as well as the expected performance of this proposed mission. LATOR will lead to very robust advances in the tests of Fundamental physics: this mission could discover a violation or extension of general relativity, or reveal the presence of an additional long range interaction in the physical law. There are no analogs to the LATOR experiment; it is unique and is a natural culmination of solar system gravity experiments.Comment: 16 pages, 17 figures, invited talk given at ``The 2004 NASA/JPL Workshop on Physics for Planetary Exploration.''

Cows Are Good Bean Market

Dairy cows will produce more butterfat on a ration in which whole (cracked) soybeans provide the protein supplement than on an ordinary ration of mixed grains which uses such a protein supplement as soybean oilmeal

Why Does Second-Cutting Red Clover Hay Slobber Animals

For years, farmers have noticed the slobbering of animals after feeding second-cutting red clover hay. Severity of this effect, however, has varied from year to year. Questions asked many times are what causes the slobbering and what can be done about it? To get the answers available, let\u27s go back about 37 years into something which appears to be totally unrelated to slobbering and follow research which has been done on a fungus, which causes a disease of red clover

Socially Disorganized Rural Communities

The article talks about the social disorganization of rural communities in the U.S. It is stated that family farming has been on the decline for decades, with the numbers of farmers dropping by 16 million since 1950 and farms decreasing by over 4 million during the past century. It is inferred that a part of a community\u27s history and way of life are being forfeited when local business are closing. According to the author, the theory of social disorganization emphasizes social integration and stability as necessary conditions for community. It offers some of the disadvantages of disorganized communities, such as the lack of collective efficacy

Evaluation of Egg Incubation Methods and Larval Feeding Regimes for North American Burbot

Incubation methods and larval feeding regimes were investigated for North American burbot Lota lota maculosa over 2 years. Three upwelling incubators were tested: 6.0‐L McDonald‐type jars, 2.0‐L pelagic egg jars, and 1.2‐L Imhoff cones. Larvae were allocated to five feeding regimes in year 1 (trial 1) and three feeding regimes in year 2 (trial 2). In trial 1, a live diet (marine rotifers Brachionus plicatilis and brine shrimp Artemia spp.) was administered from 11 d posthatch (dph) until introduction of a commercial diet at 21, 31, or 41 dph; the fourth treatment applied the commercial diet exclusively starting at 11 dph, and the fifth treatment used only the live diet. Trial 2 examined (1) exclusive use of live feed beginning at 16 dph; (2) use of live feed at 16–50 dph, which was combined with commercial feed at 31–50 dph, and use of only the commercial diet at 51–76 dph; and (3) use of the live diet at 16–50 dph, the addition of frozen brine shrimp at 31–50 dph, and use of the commercial diet at 51–76 dph. Approximate stocking densities for feeding trials were 25 larvae/L in trial 1 and 250 larvae/L in trial 2. Survival and total lengths (TLs) were measured at 52 dph in trial 1 and at 76 dph in trial 2. Incubation trials showed that Imhoff cones or pelagic egg jars significantly improved embryo survival relative to McDonald jars. Larvae fed a live diet for an extended time had significantly higher survival and TLs in both trials. Introduction of a commercial diet at 31 or 41 dph after live‐diet feeding was successful. This study provides a basis for further development of burbot aquaculture
