Using deep exposures (∼ 10 s) with the ROSAT HRI, we have performed fluxlimited surveys for X-ray sources in the vicinity of the Hyades-age open stellar clusters NGC 6633 and IC 4756, detecting 31 and 13 sources respectively. Our primary aim is to search for so-far unrecognised cluster members. We propose identifications or classifications (cluster member, field star, extragalactic field object...

The only extraterrestrial life detection experiments ever conducted were the three which were components of the 1976 Viking Mission to Mars. Of these, only the Labeled Release experiment obtained a clearly positive response. In this experiment C radiolabeled nutrient was added to the Mars soil samples. Active soils exhibited rapid, substantial gas release. The gas was probably CO2 and, possibly...

In the conditions of war russia against Ukraine, which began on February 24, 2022, Ukrainian universities are playing roles that were not characteristic them in peacetime. To greatest extent, this concerns university’s third mission, serving society and responding to its urgent needs. The purpose study is identify characterize new meaningful directions for implementing mission university post-w...

Shocks and discontinuities in space plasmas have received much attention in both theoretical studies and spacecraft data analyses. The advent of multi-spacecraft missions, such as ISEE, have provided for a vast improvement of experimental information available on these structures. The ESA CLUSTER, multi-spacecraft mission presents the community with a unique opportunity to investigate these str...

The interaction of the solar wind with the Earth magnetosphere generates a broad variety of plasma waves through different mechanisms. The four Cluster spacecraft allow one to determine the regions where these waves are generated and their propagation directions. One of the tools which takes full advantage of the multi-point capabilities of the Cluster mission is the wave telescope technique wh...

Using current methods, it is virtually impossible to determine the impact of a cyber attack on the attainment of mission objectives. Do we know which mission elements are affected? Can we continue to operate and fulfill the mission? Should we wait for recovery? Can we salvage part of the mission? Since it is currently so difficult for humans to comprehend the mission impact of a cyber incident,...

To meet its objective of reducing operations costs without incurring a corresponding increase in risk, NASA is seeking new methods to automate mission operations. This paper examines the state of the art in automating ground operations for space missions. A summary of available technologies and methods for automating mission operations is provided. Responses from interviews with several space m...

Purpose – The purpose of this paper is to assess the records system of a Turkish public university, using the example of Hacettepe University in order to develop records management programs in Turkish universities. Design/methodology/approach – A survey method is used in this research; data are gathered through literature reviews, legal analysis, questionnaires, and interviews. Analyzing the in...

This study examines the influence of different types of structural assurance on consumer purchasing intentions in business-to-consumer (B2C) electronic commerce. Prior research findings regarding how different types of structural assurance impact consumer purchasing intentions has been limited. Based on the institution-based trust theory, perceived trust theory and the psychological contract th...
