HGIS: A Healthcare-Oriented Approach to Geographic Information Systems
2019The healthcare sector is rapidly changing to incorporate new technologies Antoni that enable the collection of unprecedented amounts of data. New paradigms such as mobile and smart healthcare are founded on these new technologies, such as the IoT, and the data they collect are no longer only medical but, instead, they refer to contextual information ...

The reaction Hg+I2→HgI+I revisited
The Journal of Chemical Physics, 1983The crossed molecular beam study of Mayer et al. (1977) on the subject reaction is revisited. The present work employs a different beam configuration and thus kinematic framework, and a larger range of relative translational energies is covered (i.e., from the threshold of 1.15 to 3.75 eV).

The Yellow Polymorphs of Mercuric Iodide (HgI2)
Helvetica Chimica Acta, 2003AbstractHgI2 crystallizes under ambient conditions from various solvents and by sublimation into three concomitant polymorphs whose colors are red, orange, and yellow. The orange and yellow phases are metastable and transform into the red phase when touched. A phase transition from red to yellow occurs at 400 K.

Blue-violet HgI/HgI2laser with wide-band optical pumping by a linearly stabilized surface discharge
Soviet Journal of Quantum Electronics, 1986A description is given of the first photodissociation laser utilizing the B–X electronic transition in mercury iodide (λ = 442, 443, 444 nm) with wide-band optical pumping of HgI2 vapor by thermal radiation from a plasma. The pump source was a linearly stabilized surface discharge with a brightness temperature Tb ≈ 25kK in the ultraviolet part of the ...

Digital Resources: HGIS de las Indias
2020HGIS de las Indias is an open-access Spanish-language database and web platform on the temporal and spatial developments in the territorial organization and settlements of all Spanish America (from Nutka to the Malvinas) during the reign of the Bourbon dynasty until the eve of the independence movements (1701–1808).

Journal of Physics D: Applied Physics, 1990
Electron impact dissociative excitation of HgI2 molecules producing the B2 Sigma +1/2 state of HgI has been studied in the case of low energy electrons. Using the most intense band of the (B2 Sigma +1/2-X2 Sigma +1/2) system of the HgI radical at 444 nm, emission cross sections have been measured in the electron energy range 1-100 eV.

Emission Cross-Sections of HgI Radicals and Hg Atoms
Spectroscopy Letters, 1990Abstract Emission bands of the (B-X) system of HgI-radicals and mercury atomic lines during transitions from various excited levels to lower levels have been observed due to collisions of N+ and N+ 2 ions and HgI2 molecules. By using the integrated intensity of these emissions, HgI2 vapor density and the charge particle density, emission cross-sections

Towards Human-Game Interaction (HGI)
As serious games, as well as entertainment games, evolve along a continuum ranging from analog to digital, including hybrid solutions, the design and role of game interfaces have become increasingly complex and central to the player experience. This position paper proposes a conceptual shift, considering the interface not merely as a structural or ...Brunella Botte +3 more

The history of cities and historical geographic information system (HGIS)
2017Research in humanities can benefit from the use of digital sources and tools. On the one hand, scholars can utilize the increasing number of digital reproductions of original sources from archives, which means that documents with optimal definition are readily available for consultation.
