The observation of small magnetic materials is one of the most important applications of electron holography to material science, because interferometry by means of electron holography can directly visualize magnetic flux lines in a very small area. To observe magnetic structures by transmission electron microscopy it is important to control the magnetic field applied to the specimen in order to prevent it from changing its magnetic state. The easiest method is tuming off the objective lens current and focusing with the first intermediate lens. The other method is using a low magnetic-field lens, where the specimen is set above the lens gap.Figure 1 shows an interference micrograph of an isolated particle of barium ferrite on a thin carbon film observed from approximately [111]. A hologram of this particle was recorded by the transmission electron microscope, Hitachi HF-2000, equipped with an electron biprism. The phase distribution of the object electron wave was reconstructed digitally by the Fourier transform method and converted to the interference micrograph Fig 1.

Irish science fiction is a relatively unexplored area for Irish Studies, a situation partially rectified by the publication of Jack Fennell's Irish Science Fiction in 2014. This article aims to continue the conversation begun by Fennell's intervention by analysing the work of Belfast science fiction author Ian McDonald, in particular King of Morning, Queen of Day (1991), the first novel in what McDonald calls his Irish trilogy. The article explores how McDonald's text interrogates the intersection between science, politics, and religion, as well as the cultural movement that was informing a growing sense of a continuous Irish national identity. It draws from the discipline of Science Studies, in particular the work of Nicholas Whyte, who writes of the ways in which science and colonialism interacted in late nineteenth and early twentieth-century Ireland.

Do So

This essay examines the figure of the pesticide-exposed intersex frog, a canary in the coal mine for public endocrinological health. Through feminist science studies and critical discourse analysis, I explore the fields that bring this figure into being (endocrinology, toxicology, and pest science) and the colonial and racial logics that shape these fields. In so doing, I attend to the multiple nonhuman actors shaping this figure, including the pesky weeds and insects who prompt pesticides’ very existence, “male” frogs who function as test subjects, and systemic environmental racism that disproportionately exposes people of color to environmental toxicants. I encourage careful examination of galvanizing environmental figures like this toxic intersex frog and I offer a method to do so.

Main Components

Numerous studies by Russian scientists and historians of science are devoted to the state science policy in the USSR and its well-known achievements, but not enough attention is paid to the negative, socially repressed aspects of the Soviet science policy. Repressions became one of the main components of the state's scientific and personnel policy in the Stalinist era. The systemic analysis of the development of Soviet science declared in the scientific literature, limited only by its indisputably outstanding achievements, without under-standing the origins, causes and mechanisms of the repressed state apparatus that operated in the same period, sharply reduces the overall picture of the reliability of the study of Soviet science. The purpose of the study is to comprehend the diverse and dramatic practice of state repression in the system of Soviet science, because in the world history of science no other developed country has experienced such large-scale and tragic events in the functioning of the scientific society.

UNSTRUCTURED Objective. The proportion of youth living with HIV/AIDS (YLH) on ART and virally undetectable is low, highlighting significant challenges for reaching the Joint United Nations Program on HIV targets. Increased attention to measurement and monitoring of care engagement highlights a needed framework for assessing progress across the care continuum. To this end, the Cascade Monitoring (CM) study was designed to assess the feasibility of using electronic health records (EHR) for cascade related implementation science outcomes. Methods. EHR data was systematically obtained from multiple clinical sites and utilized to capture the CDC’s four continuum of care measures. Results. The use of EHR data works well for assessing patterns of completed visits. Sites with access to data management resources work more efficiently for CM study purposes. Conclusions. Site data management resources should be a part of the selection process when identifying site partners for clinical studies that plan to use EHR data.
