TL;DR: The Scar That Binds as mentioned in this paper examines the central metaphors of the Vietnam War and their manifestations in American culture and life, and discusses an ideology of unity that has emerged through widespread rhetorical and cultural references to the war.
Abstract: In The Scar That Binds, Keith Beattie examines the central metaphors of the Vietnam War and their manifestations in American culture and life. Blending history and cultural criticism in a lucid style, this provocative book discusses an ideology of unity that has emerged through widespread rhetorical and cultural references to the war. A critique of this ideology reveals three dominant themes structured in a range of texts: the "wound," "the voice" of the Vietnam veteran, and "home." The analysis of each theme draws on a range of sources, including film, memoir, poetry, written and oral history, journalism, and political speeches.

TL;DR: A chimaerid holocephalian, Chimaera zangerli sp nov, was described from both palatine tooth plates, two tooth plate fragments, and part of the chondrocranium in a nodule from the Maastrichtian of Antarctica as mentioned in this paper.
Abstract: A chimaerid holocephalian, Chimaera zangerli sp nov, is described from both palatine tooth plates, two tooth plate fragments, and part of the chondrocranium in a nodule from the Maastrichtian of Antarctica Possibly the oldest known chimaerid, C zangerli sp nov exhibits a tooth plate which is a morphological intermediate between that of the Jurassic Ganodus and the Oligocene C rupeliensis The presence of C zangerli sp nov before the end of the Cretaceous is evidence of the early evolution of the Chimaeridae, considered the most derived of the chimaeroid fishes

TL;DR: A ground-based atmospheric lidar system that utilizes a holographic optical telescope and scanner has been developed and successfully operated to obtain atmospheric backscatter profiles as discussed by the authors, using a volume phase reflection HOE.
Abstract: A ground-based atmospheric lidar system that utilizes a holographic optical telescope and scanner has been developed and successfully operated to obtain atmospheric backscatter profiles The Prototype Holographic Atmospheric Scanner for Environmental Remote Sensing is built around a volume phase reflection holographic optical element (HOE) This single optical element both directs and collimates the outgoing laser beam as well as collects, focuses, and filters the atmospheric laser backscatter while offering significant weight savings over existing telescope mirror technology Conical scanning is accomplished as the HOE rotates on a turntable sweeping the 12 mrad field of view around a 42° cone During this technology demonstration, atmospheric aerosol and cloud return signals have been received in both stationary and scanning modes The success of this program has led to the further development of this technology for integration into airborne and eventually satellite Earth-observing scanning lidar telescopes

TL;DR: In this article, the authors used hydrazine and tetrakis-(dimethylamido)titanium precursors for the low temperature chemical vapor deposition of TiN thin films between 50°C and 200°C at growth rates between 5 to 35 nm/min.
Abstract: Hydrazine and tetrakis-(dimethylamido)titanium have been used as precursors for the low temperature chemical vapor deposition of TiN thin films between 50°C and 200°C at growth rates between 5 to 35 nm/min. At hydrazine to TDMAT ratios of 50:1 and 100:1 the resulting films show an increase in the Ti:N ratio with increasing deposition temperature. They contain 2% carbon, and varying amounts of oxygen up to 36% as a result of diffusion after air exposure. The low temperature growth is improved when hydrazine-ammonia mixtures containing as little as 1.9% hydrazine are used. Their Ti:N ratio is almost 1:1 and they contain no carbon or oxygen according to RBS. The TiN films grown from pure hydrazine or the hydrazine-ammonia mixture have some crystallinity according to x-ray diffraction and their resistivity is on the order of 104µω cm. The low temperature growth is attributed to the weak N–N bond in hydrazine and its strong reducing ability. In these films, the Ti:N ratio is approximately 1:1.

TL;DR: A strange convergence is taking place between the roles of programmers and end-users, where professional programmers are now end users of complex IDEs (Integrated Development Environments) similar to tools for non-programmers.
Abstract: End-User Programming has not lived up to expectations: today's computer world is dominated by "fatware" programs with hundreds of features, not simple applications built by the users themselves. Yet a strange convergence is taking place between the roles of programmers and end-users. Professional programmers are now end users of complex IDEs (Integrated Development Environments) similar to tools for non-programmers. On the other end of the scale, end users of major applications are gradually eased into real programming by extensive customization, macro recorders, "wizards", and GUI builders. In between are the informally-trained software professionals we call "blended-user programmers" who configure computers and networks, control industrial machines, and build active Web pages and business applications. Like conventional programmers, they are paid to program full-time, and develop skills in a variety of tools. Like end-users, their knowledge is applied and experimental rather than theoretical. Many started as end users, but moved into these software careers instead of becoming "gurus" or "gardeners" [1] who help other users.

TL;DR: In this paper, the decomposition of tetrakis(dimethylamino)titanium (TDMAT) was studied in a high-temperature flow reactor (HTFR) by molecular beam mass spectrometry (MBMS).
Abstract: Tetrakis(dimethylamino)titanium (TDMAT) is an important precursor for TiN, TiCN, and TiSiN thin films in chemical vapor deposition. In order to better understand how the gas phase chemistry influences the formation of these films, the decomposition of TDMAT has been studied in a high-temperature flow reactor (HTFR) by molecular beam mass spectrometry (MBMS). Two kinetic regimes have been observed as a function of temperature. Rate expressions and mechanistic implications will be presented. Further studies are in progress to identify the gas phase species relevant to the decomposition mechanism of TDMAT.
TL;DR: In this paper, a fractional factorial design was used to study the effects of deposition temperature, C:Ti input, H: Ti input, reactor pressure, and total mass flow on TiC film composition.
Abstract: TiC and Ti-W-C films have been produced by chemical vapor deposition (CVD). A fractional factorial design was used to study the effects of deposition temperature, C:Ti input, H:Ti input, reactor pressure, and total mass flow on TiC film composition. Statistical models were developed for both titanium at.% and C:Ti in the film. It was found that the most significant affect on titanium at.% was the interaction of temperature, pressure and total mass flow. The most important affect on the C:Ti in the deposited film was the interaction C:Ti input, H:Ti, and total mass flow. Ti-W-C films have been deposited at 1050°C at various (TiCl 4 +W(CO) 6 )/CH 4 inlet ratios ranging from 0.53 to 1.01. The characterization of the films revealed that the changes in deposition rate, crystallinity, film orientation, and morphology of various Ti-W-C compositions were affected by (TiCl 4 +W(CO) 6 )/CH 4 inlet ratios.
TL;DR: In this article, the extent of silane reactivity was dependent upon the relative amounts of Ti(NMe2)4 and NH3 and each TDMAT molecule activated multiple silane molecules.
Abstract: Silane activation, predominantly in the gas phase, has been observed during the chemical vapor deposition of Ti-Si-N thin films using Ti(NMe2)4, tetrakis(dimethylamido)titanium, silane, and ammonia at 450°C, using molecular beam mass spectrometry. The extent of silane reactivity was dependent upon the relative amounts of Ti(NMe2)4and NH3. Additionally, each TDMAT molecule activates multiple silane molecules. Ti-Si-N thin films were deposited using similar process conditions as the molecular beam experiments, and RBS and XPS were used to determine their atomic composition. The variations of the Ti:Si ratio in the films as a function of Ti(NMe2)4 and NH3 flows were consistent with the changes in silane reactivity under similar conditions.
