Effects of grazing adaptation on intake, ruminal fermentation, blood metabolites, and body weight change in dairy cows after turning out to pasture in early spring
No full textThis study investigated the effect of adaptation to grazing in early spring on herbage intake, ruminal fermentation parameters, blood metabolite concentrations, and body weight change in dairy cows. The experiment was conducted on eight rumen-cannulated non-lactating cows in the early spring period. Four cows were adapted to grazing by stocking for 4 hr for 1 week (ADP group). The other cows were kept in a barn during the period (CON group). Then, both groups of cows were stocked together throughout a day on a 1 ha pasture for 3 weeks (experimental period). In the first week of the experimental period, compared to the CON group, the ADP group had a higher herbage intake, ruminal NH3-N and total VFA concentration, and blood urea concentration, but the NEFA concentration was lower in the ADP group (p < .01). During the subsequent weeks, there were little differences in ruminal fermentation parameters and blood metabolites. Cows in the ADP group maintained their body weight, but cows in the CON group lost 60 kg of body weight in the first week of the experimental period
Bound wave release induced by short wave breaking-true or false?
No full textIt is widely assumed that incident bound long waves are released during short wave breaking, subsequently propagating to the shore as a free wave. Statements asserting this release are either unattributed, or loosely attributed to Longuet-Higgins and Steward (1962). However, the author is unaware of convincing evidence of such release of bound long waves as a result of short wave breaking, while there appears to be strong evidence to the contrary. The author's interpretation is that Longuet-Higgins and Steward (1962) suggest that the bound wave will decay in amplitude following short wave breaking. This is in agreement with a number of author's date sets and some data from other recent data sets, including field observations of strong nearshore dissipation of long waves. A surf beat similarity parameter is also suggested, which distinguishes different regimes of surf beat generation

Case study on the public / private relationship in high-density low-rise residential areas of central Tokyo
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Architecture, 2012.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (p. 114-116).This thesis starts with the interest in the undefined open spaces of high-density low-rise (HDLR) residential areas in Tokyo. In these spaces, one can witness numerous examples of overlapping public and private uses. For example, public streets are often appropriated as private gardens by a subtle but prominent gesture by residents to place many potted plantations on the street. These phenomenons contribute to the vitality and safety of the neighborhood, as well as reflecting an effective use of space in a limited inner-city environment. The aim of this thesis is to propose a housing development strategy that nourishes these qualities of the HDLR residential environment. The proposal seeks to provide an alternative to prevailing high-rise developments, to allow for more flexibility between public and private spaces. This thesis is a hypothetical and academic exercise, which builds up on premises based on current statistics and characteristics of the project site. The design maintains and starts with the inherited urban fabric of the HDLR site, and proposes an individual renewal process of houses that collectively metamorphosize into an environment with greater sharing of public and private space. This neighborhood will continue to evolve as the population and lifestyles of residents change in the future.by Saki Mizuguchi.S.M
