The lower mass limit on the lightest supersymmetric particle, using ALEPH data up to 188.6 GeV

The lightest srpersymmetric particle (LSP) is expected to be stable, massive and neutral. Direct searches for supersymmetric particles in the context of the minimal supersymmetric extension to the standard model have been performed with the ALEPH detector. Using about 175pb-1 of data with centre-of-mass energies near 189GeV a limit on the mass of the LSP of M_LSP>32.3GeV/c2 at 95% confidence can be derived, assuming R-parity is conserved.The lightest srpersymmetric particle (LSP) is expected to be stable, massive and neutral.

The 1947 Iowa corn yield test

The Iowa corn yield test is conducted annually to provide impartial comparable performance records on a relatively large number of hybrid combinations. Each hybrid tested is ranked by a performance score based on yield, dry matter content of grain, lodging\u27 resistance and the percentage of ears held on the stalks. In view of the present world food need, it is important that farmers plant hybrids adapted to their particular locality. The information. presented gives a reliable estimate of the relative performance of a considerable number of hybrids when grown in different areas of Iowa

The 1955 Iowa corn yield test

This bulletin reports the results of the thirty-sixth annual Iowa Corn Yield Test. Similar tests have been conducted by the Iowa Crop Improvement Association in cooperation with the Iowa Agricultural Experiment Station since 1920. The purpose of these tests is to provide information\u27 to help Iowa farmers select the hybrids best adapted for their areas. More than 100 companies sell closed-pedigree hybrid seed com in Iowa. Other individuals and companies produce and sell only open-pedigree hybrids. With so many hybrids available, it isn’t easy to choose the ones best adapted to a particular farm or location. The function of the Iowa Com Yield Test is to help make this task easier

The 1948 Iowa corn yield test

This bulletin presents the results of the 1948 Iowa Corn Yield Test. The purpose of the test is to determine the value of hybrids for all parts of Iowa. In 1948 there were 326 entries. The state was divided into four sections and these sections were divided into 12 districts. You will find a map in the bulletin showing the division of the state and approximate location of the cooperating farms where the hybrids were tested. The test is open to all producers of hybrid corn seed. In addition to the entries made by seed producers, the Iowa Corn and Small Growers’ Association entered 10 of the most widely grown hybrids in each section of Iowa. These 10 were determined by a survey of farmers throughout the state. In the back of the bulletin, you’ll find an index listing the hybrids tested in 1948. The index also lists the tables showing the performance of each entry

The 1950 Iowa corn yield test

Each year Iowa farmers are faced with the problem of choosing adapted hybrids for their farms. The appearance of the seed in the bag is an inadequate measurement of value. The real test of value comes from an unbiased measure of performance of hybrids that are offered for sale. The purpose of the Iowa Corn Yield Test is to give you this kind of information. This test is not a “contest” . There are no prizes or awards. It is a test to measure differences among hybrids. W e hope the data presented in this bulletin will help you to select the best adapted hybrids available for planting in 1951. The Iowa Corn Yield Test is conducted annually by the Iowa Corn and Small Grain Growers’ Association in cooperation with the Iowa Agricultural Experiment Station
