Mass Scale Production

Context: Although the mass-transport system Transmilenio provides audio information for travelers’ guidance, this is not helpful enough to blind users who are not able to transit easily within the system. For these reason, portable guidance devices are needed to improve the level of autonomy of the visually impaired people while using the transport system.Method: A review of aid devices to improve the level of autonomy of people with visual impairment was conducted so as to define the most practical technology for building an affordable device usable in the city of Bogotá. Subsequently, the functional modules of the device were defined, including file storage, sound reproduction, user interface and satellite geolocalization and location. Once built, the operation of the device was tested with 10 volunteers in condition of visual impairment who were oriented with the device between two main stations of one Transmilenio line; a final statistical study was conducted on the operation and usability perception of the device by the users.Results: 100% of the users were able to reach their destination successfully in the pilot test. In regards to the usability perception, users highlighted features such as sound indications for setting the device and orientation guidance throughout the journey. On the other hand, one of the main difficulties found was to correctly identify the bus approaching the stop and similarly locating the corresponding boarding door, as multiple bus routes may alight in the same door.Conclusions: The device was built incorporating low-cost technologies intended to make it affordable in an eventual mass—scale production. Likewise, a discreet design was chosen so as to lessen the risk of robbery, which unfortunately is a frequent issue in the Transmilenio system due to overcrowding of buses and stations. Additionally, we remark that the prototype can be made smaller by using special—purpose circuit boards. Policy-makers may take into account these considerations for an eventual wide implementation as part of governments’ plans for mobility inclusion in mass-transport systems for disabled people, in comparison with other alternatives such as smart cell phonesLanguage: Spanish.

Biological sources of bacteria ,fungi, and plants are playing a major role in the reduction of metallic nanoparticles such as gold, as it attributed as an eco-friendly and contributed in application in nanotechnology. This study include the biological synthesis of gold nanoparticles using the culture supernatant of local Serratia spp. isolate. Gold(III) chloride trihydrate ( HAuCl2) in concentration1× 10-³ M added to supernatant separately. Their respective supernatants were examined for ability to produce gold nanoparticles, The events happend was in a dark place at 37Cº. After 24 h, it was observed that the color of the solutions turned from pale yellow to dark purple. The gold nanoparticles were characterized by: UV-Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR) to ensure presence of different functional groups, respectively ,X-Ray Diffraction Analysis (XRD), finaly,scanning electron microscopy (FE-SEM) to determined AuNPs size and shape. Results: The gold nanoparticles were approximatly uniform in size 57.17 nm , triangle in shape and FTIR spectra revealed the presence of various functional groups in the gold nanoparticles which were also present in the bacterial extract. Conclusion: The current approach suggests that rapid synthesis of nanoparticles would be feasible in developing a biological process for mass scale production of gold nanoparticles.

ABSTRACTA large effort has been undertaken since nearly 2 years by 14 research institutes (the “Crystal Clear” collaboration, CERN RD project 18), in order to develop and investigate new dense, radiation hard and fast inorganic scintillators suitable for very good resolution electromagnetic calorimeters to be built at the new high luminosity accelerators. Other fields of interest like nuclear physics, gamma ray astronomy, medical imaging (PET), safety systems and non destructive industrial applications are also rapidly growing. Progress on cerium fluoride will be reviewed with some comments about mass scale production and cost considerations. The pro's and con's of potentially cheaper solutions based on fluoride glasses or lead compounds will be discussed. Finally some attractive candidates will be mentioned for low energy gamma ray applications.

Isolating cellulose from citrus processing waste without employing chemicals has so far been an unfulfilled goal of chemical research applied to the valorization of a widely available biowaste, annually totaling >100 million tonnes. We have applied hydrodynamic cavitation using a Venturi-type reactor for the extraction of all valued bioproducts of industrial citrus processing waste in water only, directly on a semi-industrial scale. After reporting the discovery of IntegroPectin in the soluble fraction of the aqueous extract, we now report the isolation of a cellulosic material in the water-insoluble fraction of cavitated lemon and grapefruit processing waste. Named “CytroCell”, the material is cellulose of low crystallinity, high porosity, good water holding capacity and good dispersibility in water. These properties open the route to mass-scale production of a useful functional material from a cheap and abundant biowaste.
