Abstract Joint research work between the University of Limoges and the State University of New York, Stony Brook, has been carried out on the impact and solidification of plasma sprayed zirconia particles. A measurement device, consisting of a phase doppler particle analyser and a pyrometer, was used to correlate the characteristic parameters of splats to those of the substrate and to the size, velocity and temperature of the impacting particles.

Abstract Within the framework of a scientific collaboration between the University of Limoges, France and the State University of New York, Stony Brook, USA, a joint work has been conducted on microstructure development and properties of plasma-sprayed molybdenum coatings. This first part of the work is devoted to the study of the effect of substrate nature and temperature on splat cooling, solidification and crystalline structure. They were investigated by means of a heat transfer model in the splat and the substrate, and the observation of splats by a scanning electron microscope and an atomic force microscope. The model takes into account melt undercooling, nucleation and crystal growth, as also a possible melting and re-solidification of the substrate. It has the capability to predict the grain size distribution under assumptions that the quality of contact between the splat and the underlying layer is uniform, nucleation takes place only on the substrate surface, crystal grains grow perpendicular to the substrate surface and no grain coalescence occurs during crystal growth.

Abstract This is the second paper of a two part series based on an interdisciplinary research investigation between the University of Limoges, France, and the State University of New York, Stony Brook, USA, aimed at fundamental understanding of the plasma-particle interaction, deposit formation dynamics and microstructure development. In this paper, the microstructure development during plasma spraying of zirconia is investigated from the point of view of deposition parameters and splat formation (part I). Splats and deposits have been produced at Limoges and Stony Brook under controlled conditions of particle parameters and substrate temperatures. The zirconia splat microstructures thus obtained are examined for their shape factors, grain size, crystallographic texture and defects. Further the deposits were analyzed for phases, porosity and mechanical properties in an effort to develop a process-microstructure property relationship. The results suggest a strong role played by the deposition temperature on the microstructure and properties of the deposit.

The Triple Helix framework focuses attention on institutional interactions within innovation systems. In particular, it is important to understand the nature of university–industry interactions such as the translation of university expertise to clinically and commercially viable innovations. This paper examines university and industry collaboration practices in the context of the innovative, entrepreneurial and translational research environment at the Buffalo Niagara Medical Campus (BNMC) and at the University at Buffalo–State University of New York. The findings highlight the importance of funding opportunities and networks. Collaboration predominantly assumes the form of consultancy, contract research and joint research. The benefits of consulting and contract research are increased knowledge production through publications, grant applications and patenting activities among BNMC scientists. Collaboration with industry through joint research is more likely to lead to entrepreneurial outcomes than any other effort to engage industry.

The collaborative networks between university, industry, and government are key sources of innovation, entrepreneurship, and regional economic development. Specifically, studies have focused on how to transfer university expertise to commercially applicable innovation through academic and industry networking. This chapter provides new insight into university and industry collaboration practices from a case study of the Buffalo Niagara Medical Campus (BNMC) and the University at Buffalo-State University of New York in the U.S. The sample of scientists surveyed shows that collaboration is actively pursued by scientists at the consortium. The collaborative networks of scientists, access to federal funding, and infrastructural support through institutional coordination locally contribute to innovative translational research. Joint research, contract research, and consulting agreement are major forms of university-industry collaborative practices. In addition, the collaboration with industry correlates with scientists' academic productivity as well as entrepreneurial outcomes.

The present article is dedicated to the problems of the organization and planning of scientific and research work of students of the University in English classes, gives grounds for the purposes and tasks of such competence-forming activity as part of the “Oriental studies” speciality program, the Russian State University for the Humanities. The article analyzes these competences, as well as forms and methods of their formation and development. The author presents demarcation of scientific knowledge and gives its characteristics: using most general qualities of a subject, objective reasoning, argumentativeness, results verifiability and reproducibility, consistency, practicality, capability to change, anticipating the future, making forecasts, methodological reflection. The author tried to analyze the reflexive component of scientific and research work of students in more detail. The article presents possible reflexive positions in the interaction between the teacher and the student and shows the dynamics of this interaction, i.e. gives a hierarchy of positions which the student can occupy in the educational process depending on how independent they are in their activity. The article also highlights the content of scientific and research work of students of the University in English classes on the basis of work with foreign texts in the macro-discourse for the “Oriental studies” speciality. The given foundations of the organization and content of scientific and research work of students have been regularly used in English language classes, as well as in optional forms of scientific activity. The students have shown good results and passion for this kind of work, which confirms the correctness of this approach.

In 1990 (Fluegeman and Orr) the writers published a short study on known North American cyclocystoids. This enigmatic group is best represented in the United States Devonian by only two specimens, both illustrated in the 1990 report. Previously, the Cortland, New York, specimen initially described by Heaslip (1969) was housed at State University College at Cortland, New York, and the Logansport, Indiana, specimen was housed at Ball State University, Muncie, Indiana. Both institutions recognize the importance of permanently placing these rare specimens in a proper paleontologic repository with other cyclocystoids. Therefore, these two specimens have been transferred to the curated paleontologic collection at the University of Cincinnati Geological Museum where they can be readily studied by future workers in association with a good assemblage of Ordovician specimens of the Cyclocystoidea.
