Preliminary Engineering Geology Report of Dam Sites on the East Fork of the Muscatatuck River in Scott, Jennings, and Jefferson Counties, Indiana
Preliminary engineering geology investigations have been made
of four proposed dam sites and their reservoir areas in the valley
of the East Fork of the Muscatatuck River and its tributaries, Big
Camp and Big Graham Creeks, in northern Scott County, southern
Jennings County, and western Jefferson County, Ind. In this report
the geologic column of the area has been divided, according to engineering
characteristics, into five units. The bedrock consists
of (in ascending order) unit 1, the Osgood Formation and the Laurel
Limestone of Silurian age; unit 2, the Waldron Shale and the Louisville
Limestone of Silurian age and the Geneva Dolomite and the
Jeffersonville Limestone of Devonian age; unit 3~ the North Vernon
Limestone of Devonian age; and unit 4~ the Devonian portion of the
New Albany Shale. These rocks are overlain at most places by
unit 5, the unconsolidated materials that range in character from
red residual limestone soils to glacial till.
The bedrock formations stratigraphically below the North
Vernon Limestone (units 1 and 2) are essentially sound rock and
offer few problems to dam and reservoir construction except the
possibility of a small amount of leakage. The Jeffersonville Limestone
(the top formation of unit 2) includes a gray limestone bed
that contains a few solution channels, but otherwise it is sound rock.
Most of the solution channels and sinkholes in the area have been
formed in the North Vernon Limestone (unit 3), and serious leakage
from the reservoir probably would occur through this formation if
it were not extensively grouted. The New Albany Shale (unit 4)
weathers quickly where it is exposed at the surface, and spillways
on the New Albany Shale must be designed to prevent the rapid erosion
of the shale under the attack of running water. The red residual
limestone soils (of unit 5) have high liquid limits, but these
materials would make a satisfactory impermeable clay core of an
earth dam. The other unconsolidated materials (glacial till, outwash
silt and sand, and loess) overlying the bedrock are thin but
sufficient in quantity to provide fill material for earth dams. Quarries
could be opened in the limestone formations at any of the dam
sites to supply concrete aggregate and fill material
Patellofemoral Pain in Female Ballet Dancers: Correlation With Iliotibial Band Tightness and Tibial External Rotation
Review of the literature reveals that ballet dancers have a high incidence of idiopathic patellofemoral pain. Twenty-four female ballet dancers were subjects in a study of the relationship between: 1) iliotibial band (ITB) tightness and patellofemoral pain, and 2) ITB tightness and degrees of tibial external rotation used in the dance demi-plie. Dancers were initially assessed by questionnaire to determine if any had knee pain. Twelve subjects mel the study criteria for patellofemoral pain, and 12 dancers without knee pain served as controls for the study. Iliotibial band tightness was measured (Ober test), and degrees of tibial external rotation used during knee flexion (demi-plie) in standing were measured in both legs of all 24 subjects (48 legs). Chi-square analysis of the collected data revealed that there was an association between ITB tightness and patellofemoral pain in the dancers. Data analysis using the Wilcoxon Rank Sum test revealed that the degree of tibial external rotation used by dancers with iliotibial band tightness was significantly greater than those without ITB tightness. This study confirms the assumption that ITB tightness in dancers may be a contributing factor to patellofemoral pain. Follow-up study is indicated to determine if the preservation or restoration of functional ITB length is effective in the prevention and/or treatment of patellofemoral pain in ballet dancers
Spanning Properties of Theta-Theta-6
We show that, unlike the Yao–Yao graph YY6, the Theta–Theta graph ΘΘ6 defined by six cones is a spanner for sets of points in convex position. We also show that, for sets of points in non-convex position, the spanning ratio of ΘΘ6 is unbounded

An adaptable urban dwelling
Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1980.MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH.Includes bibliographical references.Adaptability in this Thesis refers to the inherent capacity of a dwelling, to accommodate changing spatial and economic requirements over time. The adaptable dwelling is intended to respond to change as a fundamental condition of the human life-cycle, and offers choices to its inhabitants when changes occur. The adaptable dwelling is intended to provide an alternative to either moving as a result of change or to tolerating a space/need mis-match. Adaptability inevitably requires some overprovision of space and/or services within the dwelling which, in turn, requires increased expenditures. Thus, a major obstacle to providing adaptable housing - quite aside from strictly architectural concerns - is an economic one. A major contention of this Thesis is that adaptability will be realized only when it is built within an economic framework that will support/justify the necessary overprovision of space and/or services. The proposed economic framework in this Thesis is based on the notion of income-generation. The dwelling is conceived as a collection of areas that the inhabitants can combine - and continuously recombine - in a variety of ways such that the inhabitants can rent to others those areas which they do not need for themselves at any given time. In this way, overprovided space and/or services can generate operating income for the inhabitant which can offset the additional expenditures required for adaptability. The architectural intent of this Thesis is to design prototypical adaptable dwellings based on these social and economic notions. The adaptable dwelling is designed to function usefully as a residence for one, two or three families - at the option of the controlling inhabitant. A dwelling conceived and designed in this manner has a significant potential for adaptability within a supportive economic framework.by John A. Winslow.M.Arch
