Policy and Organizational Considerations for Improving Transfer of University Research Information and Effecting Availability of Expertise to State Agencies
No full textThe troubled state of financing of the Water Resources Research Center (WRRC) precipitated a review of the WRRC, its role, its relation to other water resources units or programs in the University, its administrative structure and its financing. An ad hoc committee appointed by
the University Vice President reported back with its reommendations on
the role of WRRC, in research, in coordination, and in communication and
outreach.
The ad hoc report was supportive of the need for strengthening and
financially supporting an expanded role for WRRC.
The University administration sensing a need for developing a coordinate
mission for Natural Resources on its various colleges and campuses
took action to set up a structure for that purpose. This consisted of
appointing an Executive Council, a technical advisory committee and four
resources sub-committees of which the Water Resources Subcommittee was one.
The Water Resources Subcommittee if activated will probably set
the goals and define the future role and authority of not only WRRC but
also of other water Centers in the University.Water Resources Research CenterBlake, G.R.. (1984).

The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Letter dated 26 June 1967 from G. R. Blake to colleagues in the Soil Science Society of America
No full textLetter dated 26 June 1967 from G. R. Blake to colleagues in the Soil Science Society of America, including Lorenzo A. Richards, on the decision by the editorial boards of the society to use the metric system exclusively in its publications, and seeking opinion on the use of a table of conversion factorsUNIVERSITY O^Fi rmesotcL INSTITUTE OF AGRICULTURE DEPARTMENT OF SOIL SCIENCE • ST. PAUL, MINNESOTA 55101 June 26, 1967 TO: Various Colleagues in SSSA FROM: G.R. Blake RE: Agronomy Journal Editorial Boards of the Soil Science Society of America have chosen to use the metric system exclusively in our publications. The question was considered in the last meeting of the Agronomy Journal Editorial Board whether or not for some of our readers it would be wise to include a compact conversion table to be printed in the Journal (perhaps on the inside cover page). I was asked to make suggestions for further consideration by the board. I have enclosed a possible table of conversion factors. I would greatly appreciate your suggestions on it. Specifically I would appreciate your comments on the following questions: (You can write on this sheet and return it if you wish.) 1. Is the list too long or too short? 2. Do you have other conversion factors to suggest? 3. Do you feel that some of those on the enclosed table could be omitted? 4. Do you have suggestions for the format of such a table? 5. Do you consider it necessary or desirable to categorize units of length, units of area, units of volume, etc.? If not, it would perhaps be best to arrange the metric units alphabetically. 6. Any other comments or suggestions you may wish to make on the value or need of such a readers guide will be appreciated. They will then be presented to the Agronomy Journal.editorial board for consideration. / 6 Jb^c^cc-, CP 7 With best personal regards CONVERSION FACTORS To convert column 1 into column 2 multiply by Column 1 To convert column Column 2 2 into column 1 multiply by Length 0.621 1.094 0.394 0.039 0.386 247.1 100.0 2.471 0.00973 2.838 0.0284 1.057 kilometer, meter, m centimeter, millimeter, 2 kilometer , 2 kilometer^, kilometer , hetare, ha 3 3 meter , m hectoliter, liter, 1 liter, 1 km cm mm Area km km2 km2 Volume hi mile, mi yard, yd inch, in inch, in 2 2 mile , mi haeccrtea,r aec,r hea acre, acre acre-inch bushel, bu bushel, bu quart (liqu: 1.609 0.914 2.54 25.4 2.590 0.00405 0.010 0.405 102.8 0.352 35.24 0.946 Mass 1.102 2.205 0.035 ton (metric) kilogram, kg gram, g ton (english) 0.9072 pound, lb 0.454 ounce (avdp), oz 28.35 Pressure 14.22 0.968 0.9807 kgs/cm2 kgs/cm kgs/cm^ lbs/inch , psi 0.0703 atmospheres, atmos 1.033 bar * 1.0197 Yield 0.446 0.891 264.2 0.87 2.119 ton (metric)/ha kg/ha kiloliters/min, kl/min hectoliters/ha hl/ha liters/sec 1/sec ton (english)/acre 2.240 lb/acre 1.12 gallons/minute, gpm 0.00379 bu/acre 1.15 ft /min 0.472 Temperatures C + 32 Centigrade, --17.8° 0° 20° 37° 100° C Fahrenheit, F 0° 32° 68° 98.6° 212° (F-32
Spectral properties of Andreev reflection from quantum turbulence in 3He-B: What do they tell about turbulent fluctuations?
No full textOne of the experimental techniques developed to measure quantum turbulence at low temperatures in 3He-B utilizes the Andreev reflection of thermal quasiparticle excitations from quantized vortices and vortex structures. We present the results of theoretical, numerical, and experimental study of Andreev scattering from quantum turbulence in 3He-B. We analyze the spectral properties of the Andreev reflection and compare these with the spectral properties of superfluid turbulence, and discuss the physical mechanisms responsible for the scaling of spectral densities. Finally, we discuss the relation between our findings and related observables in ordinary turbulence
Plangebied Blake Beemd 14 te Soerendonck, gemeente Cranendonck; archeologisch vooronderzoek: een bureauonderzoek en inventariserend veldonderzoek (verkennend booronderzoek).
No full textIn opdracht van B en W Architecten heeft RAAP begin oktober 2018 een archeologisch vooronderzoek uitgevoerd in de vorm van een bureauonderzoek en inventariserend veldonderzoek (verkennend booronderzoek) voor het plangebied Blake Beemd 14 te Soerendonck in de gemeente Cranendonck. Volgens het bestemmingsplan rust op het plangebied een dubbelbestemming “waarde archeologie”, wat betekent dat alleen bouwwerken tot 100 m2 zijn toegestaan. In het plangebied is de bouw van een landbouwschuur gepland met een omvang van 1300 m2, zodat archeologisch onderzoek nodig is.
Uit het bureauonderzoek blijkt dat het plangebied ligt op de flank van het beekdal van de Buulder Aa, met hoge zwarte enkeerdgronden op de hogere gronden en lage enkeerdgronden met moerig materiaal in het dal. In het beekdal zijn op meerdere plekken resten van een kasteel gemeld, waarvan één melding van muurresten en houten palen direct ten zuiden van het plangebied. De andere melding betreft kasteel De Burgskens, circa 600m zuidoost van het plangebied, aan de zuidzijde van het dal. Ook de studie van historisch kaartmateriaal bevestigt de ligging van het plangebied in het beekdal, getuige de aanwezige beemden. Zowel ten oosten als ten westen van het plangebied liep een oude weg die het beekdal kruiste. Aanwijzingen voor een kasteel in de onmiddellijke buurt van het plangebied zijn op de historische kaarten niet gevonden. Dit in tegenstelling tot de locatie van De Burgskens, waar op de historische kaarten grachten staan opgetekend. Die grachten zijn ook op de huidige hoogtekaarten nog herkenbaar. In het plangebied is niets wat wijst op (historische) vergravingen.
Op basis van het bureauonderzoek werd voor het plangebied bovendien een verwachting uitgesproken voor bewoningsresten uit zowel de periode van jager-verzamelaars als uit de landbouwers periode. In het beekdal zouden dan lokaal afvaldumps of jachtactiviteiten te verwachten zijn. Daarnaast werden in de omgeving van het plangebied resten van beekovergangen en (zie hoger) een verondersteld kasteel verwacht.
Uit het veldonderzoek is gebleken dat de bodem te nat is voor bewoningsresten. Het plangebied ligt volledig in het beekdal. Desondanks ontbreken moerige lagen en is de bovengrond 40 cm verploegd tot aan de C-horizont, zodat geen (intacte) afvaldumps of jachtresten meer worden verwacht. Voorts is uit het onderzoek gebleken dat de beekovergangen en muurresten van het veronderstelde kasteel buiten het huidige plangebied liggen, tenminste 100 meter zuidelijker tegen de Buulder Aa. Op basis van de studie van het historisch kaartmateriaal, de kenmerken van het vondstmateriaal ter hoogte van het veronderstelde kasteel en de ligging zo dicht bij de weg en de beek, is bovendien niet ondenkbaar dat de eerder aangetroffen resten aan een historische beekovergang gerelateerd moeten worden en niet aan een kasteel.
Aangezien in het onderzochte plangebied geen archeologische resten meer worden verwacht en de toekomstige bodemverstoring bovendien maar zeer beperkt is (< 50 m2 aan totaal poer-oppervlak), ziet RAAP vanuit archeologisch oogpunt geen verdere restricties ten aanzien van de bouw van de landbouwschuur
