The partnership: Space shuttle, space science, and space station

An overview of the NASA Space Station Program functions, design, and planned implementation is presented. The discussed functions for the permanently manned space facility include: (1) development of new technologies and related commercial products; (2) observations of the Earth and the universe; (3) provision of service facilities for resupply, maintenance, upgrade and repair of payloads and spacecraft; (4) provision of a transportation node for stationing, processing and dispatching payloads and vehicles; (5) provision of manufacturing and assembly facilities; (6) provision of a storage depot for parts and payloads; and (7) provision of a staging base for future space endeavors. The fundamental concept for the Space Station, as given, is that it be designed, operated, and evolved in response to a broad variety of scientific, technological, and commercial user interests. The Space Shuttle's role as the principal transportation system for the construction and maintenance of the Space Station and the servicing and support of the station crew is also discussed

Preparation and Stability of Diphenyl Amine Hydronitrate

In connection with certain proposed studies the question of the preparation of diphenyl amine hydronitrate, or diphenyl ammonium nitrate, arose. A search of the literature revealed no record of this substance. The nearest equivalent reported was the perchlorate salt of diphenyl amine (Ber. 43, 1085-86. 1910). This compound was obtained upon treatment of a carbon tetrachloride solution of the amine with 70% perchloric acid added dropwise

Lambs Put OK On Silage

In lamb feeding trials here at Iowa Station during the past winter, we had two main objectives in mind: (1) To find whether it would pay to feed lambs corn silage and \u27alfalfa hay instead of hay and (2) whether one can and should push lambs up to a good feed of shelled corn and hold them at that level, or whether the amount of corn should be shifted from time to time in accordance with the appetite of the lambs to keep them on full feed

Report & Recommendations Legal Scholar Team

The Report’s Recommendations for next steps reflect and incorporate the multiple experiences, false starts, insights, frustrations and new beginnings that represent the various ways that diversity works within the different sectors of the legal profession. We have included Recommendations that are already being used as well as some that are ambitious and aspirational. Within each of the four sectors of the profession, the recommendations are broadly categorized, but not prioritized. We recognize that every individual or organization will have its own priorities based on its unique circumstances. We do encourage the Report’s users to select and prioritize recommendations for next steps that they can implement in their own environments

Decentralized Adaptive Control for Collaborative Manipulation of Rigid Bodies

In this work, we consider a group of robots working together to manipulate a rigid object to track a desired trajectory in $SE(3)$. The robots do not know the mass or friction properties of the object, or where they are attached to the object. They can, however, access a common state measurement, either from one robot broadcasting its measurements to the team, or by all robots communicating and averaging their state measurements to estimate the state of their centroid. To solve this problem, we propose a decentralized adaptive control scheme wherein each agent maintains and adapts its own estimate of the object parameters in order to track a reference trajectory. We present an analysis of the controller's behavior, and show that all closed-loop signals remain bounded, and that the system trajectory will almost always (except for initial conditions on a set of measure zero) converge to the desired trajectory. We study the proposed controller's performance using numerical simulations of a manipulation task in 3D, as well as hardware experiments which demonstrate our algorithm on a planar manipulation task. These studies, taken together, demonstrate the effectiveness of the proposed controller even in the presence of numerous unmodeled effects, such as discretization errors and complex frictional interactions

Functional forms of competence: Interviewing

Citation: Huffcutt, A. I., Culbertson, S. S., & Riforgiate, S. E. (2015). Functional forms of competence: Interviewing. In A. F. Hannawa & B. H. Spitzberg (Eds.), Communication Competence (Vol. 24) (pp. 431-448). Boston: De Gruyer Mouton.Employment interviews are ubiquitous in the workplace, providing a necessary step in the hiring process and influencing organizational composition and applicant employment. Research pertaining to professional interviewing is frequently conducted outside of the communication discipline, yet the nature of the interview interaction is highly communicative. The purpose of this chapter is to develop a solid foundation for understanding communication in employment interviews by utilizing the concept of communication competence as a theoretical basis. Specifically, we address aspects of communication effectiveness and appropriateness in employment interviews, including how they vary according to the degree of their standardization. For instance, both parties (interviewer and interviewee) have the goal of reducing uncertainty, although the nature of those goals differ (e.g., organizational perspectives regarding potential interviewee performance verses interviewee perceptions of job fit and the likelihood of being offered the job). Directions for future research are presented, including a pressing need for research examining how the two parties adjust communication during the interaction based on perceptions of the other’s communication behaviors

Soybean and alfalfa hays for wintering pregnant ewes

Since the soybean acreage has increased in Iowa and the Corn Belt, the determination of the economic feeding value of this plant deserves attention. Alfalfa and clover have long been considered good legume hays for sheep. Because of the increase in soybean production, which involves a greater volume of soybean hay, the question naturally arises as to how this legume hay compares in feeding value with clover and alfalfa. With this question in mind four lots of pregnant ewes were experimentally fed on soybean and alfalfa hays and certain combinations of these two hays. The results secured are reported herein

Dispute Resolution in the Provincial Courts of the Third Dynasty of Ur.

This dissertation is an investigation of dispute resolution as practiced in the two best-documented provinces of the strongly centralized state of the Third Dynasty of Ur (Ur III, ca. 2100-2000 BCE), Umma and Lagash. This southern-Mesopotamian state left tens of thousands of administrative documents reporting on a variety of economic and administrative activities, and this project focuses on approximately 370 of them, in particular those identified by the Sumerian term ditila (“case closed”) that record the outcome of dispute proceedings. The corpus utilized for this undertaking consists both of ditila-documents analyzed by Adam Falkenstein in his 1956 treatment of the topic, as well as many that have been identified or published since then. Previous studies of these documents have viewed them as evidence of “law” and as sources for the study of Sumerian linguistics. The approach adopted in this dissertation, however, views the texts as limited administrative summaries of procedures, and, inspired by studies in the anthropology of law, mines them for evidence of social groupings, mobility, and competition among provincial elites and their associates within the 38-year window covered by the texts. The study shows that, in spite of long-standing images of the Ur III state as a static, despotic entity, there were differences between the two provinces and changes in the nature of courts over time. The findings of other recent studies that have noted variations in administrative organization among the provinces are corroborated, while it is also demonstrated that there were regional differences in the organization and execution of disputing practices. The latter point indicates that there was not a centrally legislated, uniformly applied body of laws overarching the state, and thus challenges the idea of an Ur III “legal system.” Moreover, it is argued that the resolution system at work in these provinces was in constant flux, subject to both local political changes as well as currents of competition among urban, provincial elites. Disputing was engaged by a number of elite families, who participated both as disputants and court officials, in order to secure and transform status and negotiate their political standing within the community.Ph.D.Near Eastern StudiesUniversity of Michigan, Horace H.
