Infrared and Ultraviolet Observations of VIRGOHI 21 and NGC 4254's Outer Disk

We present the results of Spitzer and Galex observations of gas/dust and star formation activities in the extreme outer disk of Virgo galaxy NGC 4254 and its surrounding regions. These observations were motivated in part by the potential existence of a “dark galaxy” in the vicinity. In the intergalactic VIRGOHI 21 region where the free-floating HI gas is found, neither UV nor mid-IR shows corresponding emission, thus providing stringent upper limits on the stellar mass and star formation rate in these clouds.On the other hand, we find clearly discernible excess ultraviolet emission in parts of the extended disk of NGC 4254, which is yet unseen in the optical and infrared. These UV emission appears different from the so-called “XUV disks” of other nearby galaxies in both their distribution pattern and physical origin, which we suggest is directly related to the gas concentration of VIRGOHI 21

Seamless metal-clad fiber-reinforced organic matrix composite structures and process for their manufacture

A metallic outer sleeve is provided which is capable of enveloping a hollow metallic inner member having continuous reinforcing fibers attached to the distal end thereof. The inner member is then introduced into outer sleeve until inner member is completely enveloped by outer sleeve. A liquid matrix member is then injected into space between inner member and outer sleeve. A pressurized heat transfer medium is flowed through the inside of inner member, thereby forming a fiber reinforced matrix composite material. The wall thicknesses of both inner member and outer sleeve are then reduced to the appropriate size by chemical etching, to adjust the thermal expansion coefficient of the metal-clad composite structure to the desired value. thereby forming a fiber reinforced matrix composite material. The wall thicknesses of both inner member and outer sleeve are then reduced to the appropriate size by chemical etching, to adjust the thermal expansion coefficient of the metal-clad composite structure to the desired value. The novelty of this invention resides in the development of a efficient method of producing seamless metal clad fiber reinforced organic matrix composite structures

Individualism and the role of the individual in British and French socialism : the early years, 1800-1848

Ph.D. University of Kansas, History 1969Individualism is a topic which·has received but scant treatment by modern scholars, although it is a subject which has prompted a great deal of commentary within the socialist movement itself. There has not been thus far any scholarly attempt to treat this topic as it relates to the Utopian Socialists or the early nineteenth century. The role of' the individual in the writings of' this school of socialist thought is a relatively untouched area of investigation. Although researchers have examined many sources for the term “ individualism,” none of them have used the numerous dictionaries of the period, 1800•1848, to explain their findings further. And, no study has sought to place both of these problems, the origins and history of individualism and the role of the individual, together into one project. As will be developed in the text, these two problems were interrelated for the six thinkers treated below.· As·the title indicates, this study has attempted to gather and digest the major thoughts of early nineteenth century British and French socialists on but one main subject:· individualism and the role of' the individual. Specifically this effort involves consideration of several questions. How did each thinker contribute toward the meaning of' the term “individualism” as it finally appeared about mid-century?· In what ways did they view the role of the individual not only under the existing social order, but in their respective alternatives to that order? As writers they faced the dilemma of indicating the rights due to both the collective social body and of each individual in it. How does one secure both the blessings of mankind, and yet realize the wealth drawn from individual spontaneity? What is, therefore, the true social contract? Furthermore, to what extent were these various intellectuals influenced in their decisions by their own national experiences? Clio was subjected to a great many pressures in order to “prove” a number of vastly different social programs. Never, in fact, was there such a pressing concern for the rights of the most numerous and the poorer elements in society. All of the thinkers examined here--Owen, Fourier, Saint-Simon, Proudhon, Cabet and Blanc--were agreed that the existing system of property relations generated and perpetuated a ·morally evil and inefficient social system. Western industrialization had brought, or was .bringing, a social order based upon dehumanization and automatism. Thus, the key question was, to quote Louis Blanc again "how to change it?" Their persistent love of humanity led such intellectuals to seek out the real, not necessarily the true, laws· of nature and history. Such laws, they assumed, existed a priori in the universe. It is the thesis of this study that, although the term individualism was used by a number of critics, the application of this term to specific social conditions which ought to be changed came from the pens of the six Utopian Socialists treated here. It was they who provided the main connotations given to individualism by various dictionaries. For this reason, only passing attention has been given to the various schools founded on their behalf. Within the chronological and geographical framework of this study, the writings of the six thinkers examined here constitute the most important sources in the early socialist movement

An investigation into the trial of a Nazi war criminal : Joachim Von Ribbentrop at Nuremberg, Germany, 1945-1946

It bu been eighteen years since the holocaust of World War II ended, and perhaps It ls now possible for a new generation of young historians to approach the Hitler era of German history minus much of the Immediate post war bitterness. Much has been written which has attempted to explain the conditions which caused the rile of Nazi Germany, but much remains o be written about the personalities within It. This report was written In the hope that by examining one of these men in his last days, and on trial for his life, a little more will be added which may help In explaining more about this era

A Perceptional Investigation into The Adoption of Timber Bridges

Perceptions of major bridge materials by four distinct groups of decision-makers were investigated within five geographic regions of the United States. Timber was rated lowest in perceived performance within each group and region. Timber was compared to prestressed concrete, steel, and reinforced concrete on eight preselected attributes. Timber was rated lowest on the attributes of low maintenance, easy to design, long life, and high strength. Only on the attribute of easy to construct did the rating for wood exceed the rating for reinforced concrete. On no attribute did timber rate higher than prestressed concrete. Highway officials who have participated in the Timber Bridge Initiative program rated timber as a bridge material statistically higher in overall performance than those highway officials who have not participated in the program
