Local man whose son served in World War I and died at home while on leave
The Bach Family Looks at 1938
Farmer James Bach opened the lid of his mail box and took quick inventory of the daily deposit the carrier left on his morning rounds. A beautiful illustrated seed catalogue, with its gaudy cover page consulting the first sign of spring, the daily newspaper, the farm magazine, a card from cousin Egbert in Detroit, who, dissatisfied with the life of his rural boyhood home had sought employment in an automobile factory, and a letter from the county agent enclosing an invitation to attend a 1938 Farm Outlook meeting was the mail. Mr. Bach submitted to the temptation to read Egbert\u27s card, although it was addressed to another member of the family. (See more in text.
Winter vs. Summer Dairying
Debate: ‘Resolved, That winter dairying is more profitable than summer dairying under present conditions in South Dakota.
Purebred Dairy Bulls Pay
Reports on the merits of dairy breeding circuits and the specific activities of two North Dakota areas (Flasher and New Salem) that have successfully implemented the program
Two Basic Dairy Feeds
Discusses the two general types of feed for dairy cows, leguminous roughage and succulent roughage
More Cows or More Care?
Encourages dairy farmers to evaluate the cost effectiveness of their herd by comparing output to the cost of care. A smaller herd is more efficient
Common Questions About Cow Testing Associations
Provides answers to the most frequently asked questions farmers had about cow testing associations. The main goal of cow testing was to ensure that the farmer was using their limited resources in a way that would increase profitability. The trained testers would visit each farm every month and evaluate the feed and milk production
Dairy Breeding Circuits on the Great Plains
Focuses on the importance of selecting quality dairy cows and bulls to breed high yielding dairy cows
Overproduction of cosmic superstrings
We show that the naive application of the Kibble mechanism seriously
underestimates the initial density of cosmic superstrings that can be formed
during the annihilation of D-branes in the early universe, as in models of
brane-antibrane inflation. We study the formation of defects in effective field
theories of the string theory tachyon both analytically, by solving the
equation of motion of the tachyon field near the core of the defect, and
numerically, by evolving the tachyon field on a lattice. We find that defects
generically form with correlation lengths of order M_s^{-1} rather than H^{-1}.
Hence, defects localized in extra dimensions may be formed at the end of
inflation. This implies that brane-antibrane inflation models where inflation
is driven by branes which wrap the compact manifold may have problems with
overclosure by cosmological relics, such as domain walls and monopoles.Comment: 31 pages, 16 figures, JHEP style; References added; Improved
