LANDSAT (ERTS) used as a basis for geological volcanological mapping in the central Andes

LANDSAT images of the central Andes (N-Chile, W-Bolivia) were effectively used for volcanological mapping of an area about 160,000 km. The map shown exhibits more and better details than the older small scale geological maps of that area. Even on a scale of 1:1,000,000 details greater than 200 m in size are recognizable. The interpretation of LANDSAT images makes it possible to establish relative age sequences of strato-volcanoes. Finally, the images will also be helpful in prospecting for mineral deposits and geothermal sources

Statistical mapping of sheet aiquile SE-20-9 (national map) making use of ERTS images

New possibilities of remote sensing by means of satellites to do research on natural resources are reported. These images make it possible to carry out integrated studies of natural resources in the shortest time possible and with small investments. Various maps and a complete description of each are included. With the use of these satellites, scientists can hopefully plan development projects at the national level

Autonomous space processor for orbital debris

This work continues to develop advanced designs toward the ultimate goal of a GETAWAY SPECIAL to demonstrate economical removal of orbital debris utilizing local resources in orbit. The fundamental technical feasibility was demonstrated last year through theoretical calculations, quantitative computer animation, a solar focal point cutter, a robotic arm design and a subscale model. During this reporting period, several improvements are made in the solar cutter, such as auto track capabilities, better quality reflectors and a more versatile framework. The major advance has been in the design, fabrication and working demonstration of a ROBOTIC ARM that has several degrees of freedom. The functions were specifically tailored for the orbital debris handling. These advances are discussed here. Also a small fraction of the resources were allocated towards research in flame augmentation in SCRAMJETS for the NASP. Here, the fundamental advance was the attainment of Mach numbers up to 0.6 in the flame zone and a vastly improved injection system; the current work is expected to achieve supersonic combustion in the laboratory and an advanced monitoring system

System, Device, and Method for Determination of Intraocular Pressure

A system for determination of intraocular pressure includes: an intraocular pressure sensor; a light source illuminating the sensor with one or more wavelengths of light; and a detector that measures emitted light from the sensor. The sensor includes a substrate member, a spacer member, and a flexible membrane, which define a sealed cavity. The flexible membrane moves in response to intraocular pressure changes. A device for measuring intraocular pressure includes: the sensor; an anchoring member attached to the sensor for immobilizing the sensor in an eye; and a protective member attached to the anchoring member and covering the sensor to prevent contact between the flexible membrane and the eye. A method for determination of intraocular pressure includes: placing the sensor in an eye; illuminating, with a light source, the sensor with one or more wavelengths of light; and detecting, with a detector, a resultant light that contains information about intraocular pressure

An Exploration of Critical Care Professionals\u27 Strategies to Enhance Daily Implementation of the Assess, Prevent, and Manage Pain; Both Spontaneous Awakening and Breathing Trials; Choice of Analgesia and Sedation; Delirium Assess, Prevent, and Manage; Early Mobility and Exercise; and Family Engagement and Empowerment: A Group Concept Mapping Study

OBJECTIVES: The goals of this exploratory study were to engage professionals from the Society for Critical Care Medicine ICU Liberation Collaborative ICUs to: 1) conceptualize strategies to enhance daily implementation of the Assess, prevent, and manage pain; Both spontaneous awakening and breathing trials; Choice of analgesia and sedation; Delirium assess, prevent, and manage; Early mobility and exercise; and Family engagement and empowerment (ABCDEF) bundle from different perspectives and 2) identify strategies to prioritize for implementation. DESIGN: Mixed-methods group concept mapping over 8 months using an online method. Participants provided strategies in response to a prompt about what was needed for successful daily ABCDEF bundle implementation. Responses were summarized into a set of unique statements and then rated on a 5-point scale on degree of necessity (essential) and degree to which currently used. SETTING: Sixty-eight academic, community, and federal ICUs. PARTICIPANTS: A total of 121 ICU professionals consisting of frontline and leadership professionals. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A final set of 76 strategies (reduced from 188 responses) were suggested: education (16 strategies), collaboration (15 strategies), processes and protocols (13 strategies), feedback (10 strategies), sedation/pain practices (nine strategies), education (eight strategies), and family (five strategies). Nine strategies were rated as very essential but infrequently used: adequate staffing, adequate mobility equipment, attention to (patient\u27s) sleep, open discussion and collaborative problem solving, nonsedation methods to address ventilator dyssynchrony, specific expectations for night and day shifts, education of whole team on interdependent nature of the bundle, and effective sleep protocol. CONCLUSIONS: In this concept mapping study, ICU professionals provided strategies that spanned a number of conceptual implementation clusters. Results can be used by ICU leaders for implementation planning to address context-specific interdisciplinary approaches to improve ABCDEF bundle implementation

The effect of laser shock peening on hardness and microstructure in a welded marine steel

Residual stress is generally considered as the main criterion in laser shock peening for enhancement of fatigue life. However, changes in material hardness, microstructure and surface roughness can also affect component performance. These three aspects are investigated in this paper for welded marine steel samples subjected to laser peening. After laser peening an increase in hardness was seen across the weld and parent metal, with the local hardness dependent upon the initial hardness of the region before peening. The increase was relatively higher for the weld metal which had lower initial hardness. The local surface displacement profiles reflected the number of laser peening layers applied, and the peening also affected the distortion of the specimen after welding

Brainwaves and Sound Synchronization in a Dance Performance

In a previous work (Lucchiari and Folgieri, 2015) we considered communication among young people. New digital-natives do not communicate in a traditional way, but they choose different means and ways. It is not a surprising conclusion that a large part of digital-natives considers obsolete both Web sites\u2019 structure and Internet navigation modes, learning instruments and paradigms and communication tools, choosing, instead, fast and immediate media like mobile phone communication, social networking and so on (Croitoru et al. 2011). Notwithstanding we could think they lack of communication skills, actually, they communicate with each other much more than ever done, using not only the verbal language, but also images, videos, sounds, and especially emotions. We named this phenomenon telepatheia or, better, sympateia, meaning that they seem to keep in contact independently by the mean. Of course, on our intention, this does not mean that we are observing a new organic evolution, but surely a kind of evolution can be traced: an era in which human and machines are evolving, influencing one each other, determining a specific kind of communication strongly influenced and related to technology. In this paper, starting from our previous studies and from our concept of \u201csympateia\u201d, we performed a new experiment related to brain rhythms synchronization. Through our experiment, described in the following chapter, We want to explore the communication mechanisms of telepathy (in the ancient Greek assumption of \u201ctelepatia\u201d\uf020that is [tele]=\u201ddistance\u201d and [pateia]=\u201demotion, feeling\u201d). This does not mean that we are trying to make humans telepathic, but we aim to deeply understand communication mechanisms among humans through human-computer interaction BCI devices. This means to change the point of view of brain and Information Technology researches, stressing the point of view of self-understanding of the own brain
