Systems and Methods for Radar Data Communication
- Miller, Brad; Bunch, Brian; Szeto, Roland
A radar information processing system is operable to process high bandwidth radar information received from a radar system into low bandwidth radar information that may be communicated to a low bandwidth connection coupled to an electronic flight bag (EFB). An exemplary embodiment receives radar information from a radar system, the radar information communicated from the radar system at a first bandwidth; processes the received radar information into processed radar information, the processed radar information configured for communication over a connection operable at a second bandwidth, the second bandwidth lower than the first bandwidth; and communicates the radar information from a...

Systems and Methods of Laser Texturing of Material Surfaces and Their Applications
- Nayak, Barada K.; Gupta, Mool C.
The surface of a material is textured and by exposing the surface to pulses from an ultrafast laser. The laser treatment causes pillars to form on the treated surface. These pillars provide for greater light absorption. Texturing and crystallization can be carried out as a single step process. The crystallization of the material provides for higher electric conductivity and changes in optical and electronic properties of the material. The method may be performed in vacuum or a gaseous environment. The gaseous environment may aid in texturing and/or modifying physical and chemical properties of the surfaces. This method may be used...
Chemochromic Detector for Sensing Gas Leakage and Process for Producing the Same
- Tate, LaNetra Clayton; Captain, Janine E.; Roberson, Luke B.; Williams, Martha K.
A chemochromic sensor for detecting a combustible gas, such as hydrogen, includes a chemochromic pigment and a textile polymer. The textile material includes a chemochromic pigment operably responsive to a combustible gas. The combustible gas sensing textile material can be made by melt spinning, solution spinning, or other similar techniques. In a preferred embodiment carbon nanotubes are used with the textile material which will increase the material strength and alter the thermal and/or electrical properties. These textiles woven into fabrics can provide garments not only with hydrogen sensing capabilities but the carbon nanotubes will allow for a range of sensing...

Business models for electronic open access journals and disciplinary differences : a proposal
- Gumiero, Katiúcia Araujo; Costa, Sely Maria de Souza
Reports results of a research that aimed at studying the use of business models in the context of open access electronic scholarly journals publishing. Additionally, the work approaches disciplinary differences, particularly in
terms of three issues, namely required publication speed, funding and features that involve the edition of a scholarly journal. In this context, the study aimed at proposing a model that allows identifying required elements to design business models appropriated to open access scholarly journals publishing. Along with identifying the elements, the study looked at the relationships between these elements and differences found between knowledge fields. Based on a bibliographic...
The impact of computer usage on scholarly communication among social scientists
- Costa, Sely Maria de Souza; Meadows, Jack
An examination has been made of the effects of using information
technology on the communication of research by
social scientists in Brazil. Two disciplines were studied –
economics and sociology – via both interviews and a questionnaire
survey. A small sample of UK social scientists was
also interviewed. The results indicate that major changes in communication
habits are occurring. These are already well advanced for
informal communication and are beginning to appear for
formal communication. Differences have been found
between economists and sociologists, with the former more
active in their use of electronic facilities. Along with such
discipline-related differences, the developments also appear
to be influenced, in part, by pressures from the...
Histological and ultrastructural analysis of cryopreserved sheep preantral follicles
- Santos, Regiane R.; Rodrigues, Ana Paula Ribeiro; Costa, Sonia Helena Furtado; Silva, José Roberto Viana; Matosa, Maria H.T.; Lucci, Carolina Madeira; Báo, Sônia Nair; Hurk, Rob Van Den; Figueiredo, José Ricardo
The aim of this study was to verify the histological and ultrastructural characteristics of sheep preantral follicles after exposure of ovarian tissue to cryopreservation in glycerol (GLY), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO) in order to determine the optimum method to store sheep ovarian tissue for later experimental or clinical use. Each ovarian pair from five mixed-breed ewes was divided into 17 fragments. One (control) fragment was immediately fixed for routine histological and ultrastructural studies and the remaining (test) fragments were randomly distributed in cryotubes, equilibrated at 20 °C/20 min in 1.8 mL of minimal essential medium...

- Celestino, Juliana Jales de Hollanda; Santos, Regiane Rodrigues dos; Lopes, Cláudio Afonso Pinho; Martins, Fabrício Sousa; Matos, Maria Helena Tavares; Melo, Mônica Aline Parente; Báo, Sônia Nair; Rodrigues, Ana Paula Ribeiro; Silva, José Roberto Viana; Figueiredo, José Ricardo de
Bovine preantral follicles within ovarian fragments were exposed and cryopreserved in absence or presence of 1.5 M glycerol (GLY), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO), undergoing a previous cooling at 20 °C for 1 h (protocol 1) or at 4 °C for 24 h (protocol 2) in 0.9% saline solution. At the end of each treatment, preantral follicles were classified as non-viable/viable when they were stained/not stained with trypan blue, respectively. To confirm viability staining, ultra-structure of the follicles was evaluated by transmission electronic microscopy (TEM). Data were compared by Chi-square test (P < 0.05). The storage...

Constituents of an Extract of Cryptocarya rubra Housed in a Repository with Cytotoxic and Glucose Transport Inhibitory Effects#
- Ren, Yulin; Yuan, Chunhua; Qian, Yanrong; Chai, Hee-Byung; Chen, Xiaozhuo; Goetz, Michael; Kinghorn, A. Douglas
A new alkylated chalcone (1), a new 1,16-hexadecanediol diester (2), and eight known compounds, were isolated from a dichloromethane-soluble repository extract of the leaves and twigs of Cryptocarya rubra collected in Hawaii. The structures of the new compounds were determined by interpretation of their spectroscopic data, and the absolute configurations of the two known cryptocaryanone-type flavonoid dimers, (+)-bicaryanone A (3) and (+)-chalcocaryanone C (4), were ascertained by analysis of their electronic circular dichroism and NOESY NMR spectra. All compounds isolated were evaluated against HT-29 human colon cancer cells, and, of these, (+)-cryptocaryone (5) was found to be potently cytotoxic toward...
Nanopatterned Graphene on a Polymer Substrate by a Direct Peel-off Technique
- Chen, T. L.; Ghosh, D. S.; Marchena, M.; Osmond, J.; Pruneri, Valerio
: A graphene (Gr) on a polyimide (PI) polymer
film (Gr−PI film), obtained by a direct peel-off technique, is
proposed and investigated. Thanks to its high transparency,
electrical conductivity, mechanical strength, and chemical
durability, the Gr−PI film is an ideal substrate for flexible
electronic and optoelectronic devices, including transistors, lightemitting
diodes, and plasmonic antennas. It is obtained using a
straightforward method. After spin coating and curing a PI film
on Gr previously grown on Cu, one can separate the Gr−PI film
from the Cu foil thanks to the difference in the adhesive energy
between the Gr−Cu and Gr−PI interfaces. The resulting Gr−PI
film shows an average electrical sheet resistance ranging from...

Tunable beam displacer
- Luis José, Salazar-Serrano; Valencia, Alejandra; Perez Torres, Juan
We report the implementation of a tunable beam displacer, composed of a polarizing beam splitter (PBS) and two mirrors, that divides an initially polarized beam into two parallel beams whose separation can be continuously tuned. The two output beams are linearly polarized with either vertical or horizontal polarization and no optical path difference is introduced between them. The wavelength dependence of the device as well as the maximum separation between the beams achievable is limited mainly by the PBS characteristics.
