Ground-Water Conditions in Arkansas River Valley in the Vicinity of Hutchinson, Kansas
This report presents the results of an investigation of the geology and ground-water conditions near Hutchinson, Kansas. The investigation was made with special reference to the possibility of developing ground water of good chemical quality for municipal supply.
The report contains a map showing the areal geology and water-table contours, logs of 40 test holes and wells, and results of mechanical analyses and determinations of permeability of samples of the water-bearing materials penetrated by the test drill. The coefficient of permeability for most of the samples tested ranged from 1,000 to 15,000 (Meinzer\u27s units). The chemical character of the ground waters in this area, as shown by analyses of 63 samples of water collected from test holes and wells, varies widely. In places the ground water is contaminated by intrusion of salt water from streams and industrial wastes. Several maps and graphs illustrating the quality of the ground water are included.
Estimates of the quantity of water available for pumping in the several parts of the area are based on studies of recharge from precipitation, yield of wells, and physical properties of the water-bearing materials. Large quantities of water are available in most parts of the area, and the quantity and quality of the water in each of several sub-areas is discussed. The area along the border of the sand dunes at the edge of Arkansas River Valley north and east of Hutchinson appears most promising for the development of a supply of water of chemical quality suitable for municipal use
Ground-Water Conditions in the Neosho River Valley in the Vicinity of Parsons, Kansas
This report presents the results of an investigation of the ground-water conditions in the Neosho river valley near Parsons, Kansas, which was made with special reference to the possibility of developing a supply of water for the Kansas Ordnance Plant. A geological reconnaissance of a part of the valley was supplemented by test drilling and by a pumping test.
It was found that the physical characteristics and thickness of the water-bearing materials comprising the alluvium are quite variable. In general the alluvium is about 35 feet thick. The upper 10 to 30 feet consists of silt and clay and the lower part, ranging in thickness from a few inches to 15 feet, consists of poorly sorted sand and gravel.
Neosho river receives water from the ground-water reservoir which in turn receives recharge from precipitation. Some recharge is supplied to the alluvium by Neosho river in times of flood. In 1942 the water table was less than 10 feet below land surface in most parts of the valley.
A pumping test was made, and from the data obtained it was computed that the alluvium has a coefficient of permeability of about 420 and a specific yield of about 20 percent. It is concluded that during periods of normal precipitation a supply of about 200,000 gallons of water daily can be developed in the Neosho valley from several wells properly distributed within an area of about 1 square mile. It is believed that the pumping rate of each well should not exceed 50 gallons a minute.
The ground water in the alluvium is very hard and contains a considerable amount of iron but it is low in chloride. The hardness is almost all carbonate hardness, so that both hardness and iron can be removed by relatively simple and inexpensive treatment
Understanding customers' holistic perception of switches in automotive human–machine interfaces
For successful new product development, it is necessary to understand the customers' holistic experience of the product beyond traditional task completion, and acceptance measures. This paper describes research in which ninety-eight UK owners of luxury saloons assessed the feel of push-switches in five luxury saloon cars both in context (in-car) and out of context (on a bench). A combination of hedonic data (i.e. a measure of ‘liking’), qualitative data and semantic differential data was collected. It was found that customers are clearly able to differentiate between switches based on the degree of liking for the samples' perceived haptic qualities, and that the assessment environment had a statistically significant effect, but that it was not universal. A factor analysis has shown that perceived characteristics of switch haptics can be explained by three independent factors defined as ‘Image’, ‘Build Quality’, and ‘Clickiness’. Preliminary steps have also been taken towards identifying whether existing theoretical frameworks for user experience may be applicable to automotive human–machine interfaces
Galaxy Morphology - Halo Gas Connections
We studied a sample of 38 intermediate redshift MgII absorption-selected
galaxies using (1) Keck/HIRES and VLT/UVES quasar spectra to measure the halo
gas kinematics from MgII absorption profiles and (2) HST/WFPC-2 images to study
the absorbing galaxy morphologies. We have searched for correlations between
quantified gas absorption properties, and host galaxy impact parameters,
inclinations, position angles, and quantified morphological parameters. We
report a 3.2-sigma correlation between asymmetric perturbations in the host
galaxy morphology and the MgII absorption equivalent width. We suggest that
this correlation may indicate a connection between past merging and/or
interaction events in MgII absorption-selected galaxies and the velocity
dispersion and quantity of gas surrounding these galaxies.Comment: 6 pages; 3 figures; contributed talk for IAU 199: Probing Galaxies

Tourism Impacts and Rankings: Methodological Myth vs. Economic Inquiry
Data, in the travel and tourism industry, has been used to inflate economic projections. The driving force behind the use of this type of information is political processes. This article explores this issue and its ramifications upon the nature of research
The Convention Bureau and the Leisure Business
The viability of the convention bureau and the nature of clientele it competes for constitute a unique part of the overall travel, tourism and leisure markets. To effectively participate in this market requires a basic understanding of the characteristics of the industry that make it viable. This includes a socio-economic analysis of the area served by the convention bureau and-the characteristics of the convention attendee. The interface of these variables can indicate the potential of different markets. This paper is purposed with detailing a specific case study incorporating these analyses
