The need for international planetary cartography planning and cooperation

Cartography is fundamental to planetary science and as such, a lack of appropriate consideration of this foundation can have and has had serious and expensive consequences to both the scientific return from planetary missions and the safety of future lander missions. In this abstract we highlight the need for, and recommend cooperative planning of, such cartographic work at the national and international level. In an effort to support the planetary exploration initiatives of the various spacefaring nations, we detail specific negative consequences of not properly accounting for cartographic constraints during mission planning and execution. We will also pose several unanswered questions that must be addressed before new exploration efforts should commence. To assure the best possible return on space exploration investments, we recommend that the following planetary cartographic issues be considered: 1. Adequate resources for mapping at all stages from mission design through calibration, operations, development of processing algorithms and software, and processing to archiving; 2. Easy access to data sets and metadata from all nations; consistent (or at least well-documented) data formats; consistent cartographic standards; 3. Cooperation and support leading to the joint analysis of data sets from many nations, in turn leading to integration in a single cartographic coordinate framework at known accuracy levels, and the ability to leverage the powerful synergistic value of multiple data sets. Possible actions that could be taken to achieve these goals will also be presented

Inpatient Physical Therapy Management For A Patient With Chronic Pulmonary Complications Secondary To Multiple Lobectomies: A Case Report

Bronchiectasis is a disease defined by abnormal dilation of the bronchi, which is a result of recurrent infections and/or chronic inflammation. A lobectomy is the surgical removal of one lobe of a lung and reduces the symptoms of bronchiectasis. Patients who undergo this surgery are more likely to have long-term pulmonary limitations. There is little to no literature regarding the long term treatment of patients who underwent multiple lobectomies. The purpose of this case report was to describe an appropriate intervention program for an 82-year-old female who suffered from multiple pulmonary complications secondary to multiple lobectomies.https://dune.une.edu/pt_studcrposter/1137/thumbnail.jp

Inpatient Physical Therapy Management For A Patient With Chronic Pulmonary Complications Secondary To Multiple Lobectomies: A Case Report

Background and Purpose: Bronchiectasis is a disease defined by abnormal dilation of the bronchi from recurrent infections and/or chronic inflammation, which can lead to irreversible lung damage. Based upon severity and patient response to conservative treatment, a lobectomy may be required to resolve their symptoms. Though surgery may provide symptom relief and improve overall quality of life, patients are likely to have long-term pulmonary complications. There are several studies regarding the treatment of patients with pulmonary limitations secondary to a lobectomy. However, there is little to no evidence regarding the long-term treatment of patients who have undergone multiple lobectomies. The purpose of this case report was to describe an appropriate intervention program for an 82-year-old female who suffered from multiple pulmonary complications secondary to multiple lobectomies. Case Description: The patient was an 82-year-old female who had multiple lobectomies at age 18 secondary to bronchiectasis. She was admitted to a skilled nursing facility (SNF) with a diagnosis of a chronic obstructive pulmonary disease (COPD) exacerbation. Her primary symptoms included generalized weakness and increased dyspnea. The prescribed intervention program included cardiovascular endurance training, dynamic standing balance activities and bilateral lower extremity (BLE) strengthening. Outcomes: The distance on the 6-Minute Walk Test (6MWT) increased by 36.0 meters (m) (140.8m to 176.8m), dynamic standing balance increased from fair+ to good, BLE strength increased from 3+/5 to 4/5 (fair to good) and ambulation distance improved from 150 ft using a two-wheeled walker (2WW) to 300 ft using a four-wheeled walker (4WW). Discussion: Incorporating cardiovascular endurance training, dynamic standing balance exercises and BLE strength training appeared to have improved this 82-year-old woman’s independence with functional mobility at discharge

New fundamental parameters of the Galactic open clusters Berkeley 26, Czernik 27, Melotte 72, NGC 2479 and BH 37

We have obtained CCD UBVI_{KC} photometry down to V ~ 21.0 for the open clusters Berkeley 26, Czernik 27, Melotte 72, NGC 2479 and BH 37. The latter has never been studied before. Cluster stellar density profiles were obtained from star counts in appropriate-sized boxes distributed throughout the entire observed fields. Based on different measured indices, we estimate the ages of Berkeley 26, Melotte 72 and NGC 2479. On the other hand, we indicate possible solutions for the cluster fundamental parameters by matching theoretical isochrones which reasonably reproduce the main cluster features in their CMDs. In the case of NGC 2479, the cluster E(B-V) and E(V-I) colour excesses and apparent distance modulus were estimated from the fit of the Zero-Age Main Sequence (ZAMS) to the colour-colour and colour-magnitude diagrams, respectively.Comment: MNRAS accepte

NIMASTEP: a software to modelize, study and analyze the dynamics of various small objects orbiting specific bodies

NIMASTEP is a dedicated numerical software developed by us, which allows one to integrate the osculating motion (using cartesian coordinates) in a Newtonian approach of an object considered as a point-mass orbiting a homogeneous central body that rotates with a constant rate around its axis of smallest inertia. The code can be applied to objects such as particles, artificial or natural satellites or space debris. The central body can be either any terrestrial planet of the solar system, any dwarf-planet, or even an asteroid. In addition, very many perturbations can be taken into account, such as the combined third-body attraction of the Sun, the Moon, or the planets, the direct solar radiation pressure (with the central body shadow), the non-homogeneous gravitational field caused by the non-sphericity of the central body, and even some thrust forces. The simulations were performed using different integration algorithms. Two additional tools were integrated in the software package; the indicator of chaos MEGNO and the frequency analysis NAFF. NIMASTEP is designed in a flexible modular style and allows one to (de)select very many options without compromising the performance. It also allows one to easily add other possibilities of use. The code has been validated through several tests such as comparisons with numerical integrations made with other softwares or with semi-analytical and analytical studies. The various possibilities of NIMASTEP are described and explained and some tests of astrophysical interest are presented. At present, the code is proprietary but it will be released for use by the community in the near future. Information for contacting its authors and (in the near future) for obtaining the software are available on the web site http://www.fundp.ac.be/en/research/projects/page_view/10278201/Comment: Astronomy & Astrophysics - Received: 25 November 2011 / Accepted: 27 February 2012 -- 14 pages, 4 figure

The rotation of Io predicted by the Poincar\'e-Hough model

This note tackles the problem of the rotation of Io with the 4-degrees of freedom Poincar\'e-Hough model. Io is modeled as a 2-layer body, i.e. a triaxial fluid core and a rigid outer layer. We show that the longitudinal librations should have an amplitude of about 30 arcseconds, independent of the composition of the core. We also estimate the tidal instability of the core, and show that should be slowly unstable.Comment: arXiv admin note: text overlap with arXiv:1111.301

Human and Robotic Mission to Small Bodies: Mapping, Planning and Exploration

This study investigates the requirements, performs a gap analysis and makes a set of recommendations for mapping products and exploration tools required to support operations and scientific discovery for near- term and future NASA missions to small bodies. The mapping products and their requirements are based on the analysis of current mission scenarios (rendezvous, docking, and sample return) and recommendations made by the NEA Users Team (NUT) in the framework of human exploration. The mapping products that sat- isfy operational, scienti c, and public outreach goals include topography, images, albedo, gravity, mass, density, subsurface radar, mineralogical and thermal maps. The gap analysis points to a need for incremental generation of mapping products from low (flyby) to high-resolution data needed for anchoring and docking, real-time spatial data processing for hazard avoidance and astronaut or robot localization in low gravity, high dynamic environments, and motivates a standard for coordinate reference systems capable of describing irregular body shapes. Another aspect investigated in this study is the set of requirements and the gap analysis for exploration tools that support visualization and simulation of operational conditions including soil interactions, environment dynamics, and communications coverage. Building robust, usable data sets and visualisation/simulation tools is the best way for mission designers and simulators to make correct decisions for future missions. In the near term, it is the most useful way to begin building capabilities for small body exploration without needing to commit to specific mission architectures

The location of Airy-0, the Mars prime meridian reference, from stereo photogrammetric processing of THEMIS IR imaging and digital elevation data

The small crater Airy-0 was selected from Mariner 9 images to be the reference for the Mars prime meridian. Initial analyses in the year 2000 tied Viking Orbiter and Mars Orbiter Camera images of Airy-0 to the evolving Mars Orbiter Laser Altimeter global digital terrain model to update the location of Airy-0. Based upon this tie and radiometric tracking of landers/rovers from Earth, new expressions for the Mars spin axis direction, spin rate, and prime meridian epoch value were produced to define the orientation of the Martian surface in inertial space over time. Since the Mars Global Surveyor mission and Mars Orbiter Laser Altimeter global digital terrain model were completed some time ago, a more exhaustive study has been performed to determine the accuracy of the Airy-0 location and orientation of Mars at the standard epoch. Thermal Emission Imaging System (THEMIS) IR image cubes of the Airy and Gale crater regions were tied to the global terrain grid using precision stereo photogrammetric image processing techniques. The Airy-0 location was determined to be about 0.001° east of its predicted location using the currently defined International Astronomical Union (IAU) prime meridian location. Information on this new location and how it was derived will be provided to the NASA Mars Exploration Program Geodesy and Cartography Working Group for their assessment. This NASA group will make a recommendation to the IAU Working Group on Cartographic Coordinates and Rotational Elements to update the expression for the Mars spin axis direction, spin rate, and prime meridian location
