Science and technology studies (STS) and critical cartography are both asking questions about the ontological fixity of maps and other scientific objects. This paper examines how a group of NASA computer scientists who call themselves The Mapmakers conceptualizes and creates maps in service of different commitments. The maps under construction are those of alien Mars, produced through partnersh...

We use the COBE 8 Differential Microwave Radiometers (DMR) 4-year sky maps to model Galactic microwave emission at high latitudes (|b| > 20 •). Cross-correlation of the DMR maps with Galactic template maps detects fluctuations in the high-latitude microwave sky brightness with the angular variation of the DIRBE far-infrared dust maps and a frequency dependence consistent with a superposition of...

By studying algae reports from different localities of the country during the past 87 years, about 6000 records information including 2567 species and infra-specifics were analyzed and distribution maps were drawn. The algae studies in the Iranian islands of the Persian Gulf, especially around Bushehr and the Khark Island by Borgesen (1930), the oldest available document is used in this study. ...

in recent years, the topic of desertification has been discussed in different ways in scientific areas. this event occurred globally, regionally and nationally and many steps were taken to stop it. desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. the identification of sensitive regions and prevention ...

This paper studies some properties of F-biharmonic maps between Riemannian manifolds. By considering the first variation formula of the F-bienergy functional, F-biharmonicity of conformal maps are investigated. Moreover, the second variation formula for F-biharmonic maps is obtained. As an application, instability and nonexistence theorems for F-biharmonic maps are given.

Can a computer system create raw data for writing the history of science? More than 40 years ago, a report about ,,The use of citation data in writing the history of science" was published (Garfield, Sher & Torpie, 1964). It concludes (p. 33), ,,it is felt that citation analysfs has been demonstrated to be a valid and valuable means of creating accurate historical descriptions of scientific fie...

Based on the premise that concept map represent an important and relevant tool for the educational process for meaningful learning of scientific concepts, the purpose of this paper is to describe and analyze a specific educational experience involving classes on ‘reptiles’ for 7th graders (15 years old in average) at a secondary school. Due to the specificity of the educational area and to the ...

viewed as a mechanical profiling technique that generates three-dimensional maps of surfaces by scanning a sharp probe attached to a cantilever over a surface. The forces that act between the tip of the cantilever and the sample are used to control the vertical distance. AFM’s potential to reach atomic resolution was foreseen in the original scientific publication2 but, for a long time, the spa...
