A compendium of physical observations from JOINT-I : vertical sections of temperature, salinity and sigma-t from R/V GILLISS data and low-pass filtered measurements of wind and currents
During February, March and April 1974, the interdisciplinary Coastal
Upwelling Ecosystems Analysis experiment known as JOINT-I took place over
the continental shelf and slope near Cabo Corveiro in the NW African upwelling
region. As part of the field program, Oregon State University
made a series of repeated hydrographic surveys from R/V GILLISS along
latitudes 21°2O'N and 2l°4O'N (Fig. 1). The more northerly line was the
site of the current meter mooring and meteorological buoy array maintained
during the same period by Oregon State University in cooperation with the
Deutsches Hydrographisches Institut, Hamburg. This report contains the
complete set of contour plots of hydrographic section and anchor station
data obtained by OSU. The low-pass filtered time series of current and
wind measurements from each OSU mooring are also included

Effects of tidal-forcing variations on tidal properties along a narrow convergent estuary
A 1D analytical framework is implemented in a narrow convergent estuary that is 78 km in length (the Guadiana, Southern Iberia) to evaluate the tidal dynamics along the channel, including the effects of neap-spring amplitude variations at the mouth. The close match between the observations (damping from the mouth to ⌠30 km, shoaling upstream) and outputs from semi-closed channel solutions indicates that the M2 tide is reflected at the estuary head. The model is used to determine the contribution of reflection to the dynamics of the propagating wave. This contribution is mainly confined to the upper one third of the estuary. The relatively constant mean wave height along the channel (<â10% variations) partly results from reflection effects that also modify significantly the wave celerity and the phase difference between tidal velocity and elevation (contradicting the definition of an âidealâ estuary). Furthermore, from the mouth to ⌠50 km, the variable friction experienced by the incident wave at neap and spring tides produces wave shoaling and damping, respectively. As a result, the wave celerity is largest at neap tide along this lower reach, although the mean water level is highest in spring. Overall, the presented analytical framework is useful for describing the main tidal properties along estuaries considering various forcings (amplitude, period) at the estuary mouth and the proposed method could be applicable to other estuaries with small tidal amplitude to depth ratio and negligible river discharge.info:eu-repo/semantics/publishedVersio
The Compound Action Potential in Subjects Receiving a Cochlear Implant
The compound action potential (CAP) is a purely neural component of the cochleaâs response to sound, and may provide information about the existing neural substrate in cochlear implant (CI) subjects that can help account for variance in speech perception outcomes

A compilation of observation[s] from moored current meters, thermographs, and wind instrument. Vol. 4. Peru continental shelf March-April 1969
A summary of moored instrument measurements over the continental
shelf of Peru is presented. Measurements of variables were made in an
upwelling zone between Pisco and San Juan, from 28 March to 9 April, 1969.
Time series of temperature and horizontal current and wind velocities were
obtained at several depths and locations by an array of moored, recording
instruments. Supplementary hydrographic and drogue measurements were
also made
Construction of Precision sMDT Detector for ATLAS Muon Spectrometer Upgrade
This paper describes the small-diameter monitored drift-tube detector
construction at the University of Michigan as a contribution to the ATLAS Muon
Spectrometer upgrade for the high-luminosity Large Hadron Collider at CERN.
Measurements of the first 30 chambers built at Michigan show that the drift
tube wire position accuracy meets the specification of 20 microns. The
positions of the platforms for alignment and magnetic field sensors are all
installed well within the required precision. The cosmic ray test measurements
show single wire tracking resolution of 100 +- 7 microns with an average
detection efficiency above 99 %. The infrastructure, tooling, techniques, and
procedures for chamber production are described in detail. The results from the
chamber quality control tests of the first 30 constructed chambers are
reported.Comment: 35 pages, 41 figure
Population policies and education: exploring the contradictions of neo-liberal globalisation
The world is increasingly characterised by profound income, health and social inequalities (Appadurai, 2000). In recent decades development initiatives aimed at reducing these inequalities have been situated in a context of increasing globalisation with a dominant neo-liberal economic orthodoxy. This paper argues that neo-liberal globalisation contains inherent contradictions regarding choice and uniformity. This is illustrated in this paper through an exploration of the impact of neo-liberal globalisation on population policies and programmes. The dominant neo-liberal economic ideology that has influenced development over the last few decades has often led to alternative global visions being overlooked. Many current population and development debates are characterised by polarised arguments with strongly opposing aims and views. This raises the challenge of finding alternatives situated in more middle ground that both identify and promote the socially positive elements of neo-liberalism and state intervention, but also to limit their worst excesses within the population field and more broadly. This paper concludes with a discussion outling the positive nature of middle ground and other possible alternatives

Current meter data from the Samoan Passage experiment : world ocean circulation experiment current meter array PCM-11 : September 1992-February 1994
The Samoan Passage experiment was designed to determine the northward transport of abyssal water through the Samoan Passage (l0°S, 170°W). This topographic constriction forms the major connection for deep (>4000 m) interbasin flow between hemispheres in the Pacific (Figure 1). This report presents current meter data from the six subsurface moorings deployed in the Samoan Passage in September 1992 and recovered February 1994.
The six subsurface moorings were deployed along a transect in the Samoan Passage (Figure 2). A total of twenty-seven current meters were attached, each measuring horizontal current and temperature, with the upper two meters on each mooring measuring pressure. All instrumentation was recovered. Instrument 5872, the top meter on mooring two experienced an electronic board failure after 5 days and stopped recording data. The pressure sensor on instrument 4412, 2990 m on mooring 1, abruptly changed levels several times, and the temperature record from instrument 5856, 2970 m on mooring six, malfunctioned after 9 months. The compass on instrument 7769 (4900 m on mooring three) failed its post-cruise calibration. It appears that the failure occurred approximately one-fourth of the way through the deployment. Because the data are vector-averages, both speed and direction are suspect. The quality of the remaining records was excellent.
The Samoan Passage current meter array contributes to the World Ocean Circulation experiment and is identified by that program as PCM-11
Traditional beliefs and practices in the postpartum period in Fujian Province, China: a qualitative study
<p>Abstract</p> <p>Background</p> <p><it>Zuo yuezi </it>is the month postpartum in China associated with a variety of traditional beliefs and practices. We explored the current status of <it>zuo yuezi </it>from social, cultural and western medical perspectives.</p> <p>Methods</p> <p>We interviewed family members (36) and health workers (8) in Fujian Province, selecting one rural and one rapidly developing urban county. We asked about their traditional beliefs and their behaviour postpartum. We used a framework approach to identify main themes. We categorised reported behaviour against their probable effects on health, drawing on Western standards.</p> <p>Results</p> <p>Respondents reported that <it>zuo yuezi </it>was commonly practiced in urban and rural families to help the mother regain her strength and protect her future health. <it>Zuo yuezi </it>included: dietary precautions, such as eating more food and avoiding cold food; behavioural precautions, such as staying inside the home, avoiding housework and limiting visitors; hygiene precautions, such as restricting bathing and dental hygiene; and practices associated with infant feeding, including supplementary feeding and giving honeysuckle herb to the infant. Respondents reported that the main reasons for adhering to these practices were respect for tradition, and following the advice of elders. Categorised against Western medical standards, several <it>zuo yuezi </it>practices are beneficial, including eating more, eating protein rich food, avoiding housework, and daily vulval and perineal hygiene. A few are potentially harmful, including giving honeysuckle herb, and avoiding dental hygiene. Some women reported giving infants supplementary feeds, although <it>zuo yuezi </it>emphasises breast feeding.</p> <p>Conclusion</p> <p><it>Zuo yuezi </it>is an important ritual in Fujian. In medical terms, most practices are beneficial, and could be used by health staff to promote health in this period. Further research on reported potentially harmful practices, such as supplements to breast feeding, is needed.</p
