It is at least two decades since the conventional robotic manipulators have become a common manufacturing tool for different industries, from automotive to pharmaceutical. The advances in manipulators and sensors have given robots the opportunity to become useful for more and more applications. Engineers have taken advantage of the extra mobility of the advanced robots to make them work in constrained environments, ranging from limited joint motions for redundant manipulators to obstacles in the way of mobile (ground, marine, and aerial) robots . However, the incorporation some of these abilities and capacities that are already being used in land, have not made their way to the sea domain. This Abstract describes the project consisting in the design, development and manufacture of a prototype manipulator arm for ROVs introducing innovative fabrication technologies. The work has been done collaboratively among ACSM Maritime Agency SL, CIMA Group and the University of Vigo.

chemical analysis, equipment design, mass spectrometry, and equipment performance
A fast and straightforward method to prototype microfluidic chip systems for dead-volume-free hyphenation to electrospray-ionisation mass spectrometry is presented. The developed approach based on liquid-phase lithography provides an inexpensive and reliable access to microfluidic chips for MS coupling which can be manufactured in any laboratory with low technical demands. The rapid prototyping approach enables the seamless integration of capillaries serving as electrospray emitters with negligible dead volume. The high versatility of the presented prototyping method and the applicability of a variety of chip-based devices in different fields of lab-on-a-chip technology are established for analytical separations by means of chip-electrochromatography–MS and for continuous-flow synthesis using microreactor technology with MS detection.

rapid prototyping, agriculture safety and health, job training program development, Education, PROGRAMMES, PROGRAMME, and PROGRAMAS
Summary(En) 8 tables 13ill., 28 ref. The purpose of this study was to develop a job training program that can deliver knowledge and skill necessary for agricultural safety and health manager. A new program development model applying rapid prototyping(RP) approach to the basic ISD model was established to develop the program. Then, a textbook for learners, a manual for instructors, additional learning material were produced based on the model. The major conclusions of this study were as follows. First, this study suggested a new type of program development model that combines RP model and linear ISD model that can apply opinion of participants to compensate the defect of traditional ISD model. Second, the material was developed by applying opinion of stakeholders of program development. By developing a prototype, interim finding, the users could evaluate it at first hand. Therefore, the materials contain the content knowledge, skill, tools(KST) that agriculture safety and health managers need when they perform the job. Also various types of activities were developed so that can the learners can apply the learned contents to the job. Third, the instructors' manual and supplementary material was developed based on learners' text book. The instructors' manual is a guidance that contains the details such as learning contents, procedure and methods so that standard lectures could be delivered regardless of who teaches. Also, supplementary material is the material contains intensified knowledge and skill related to the contents of learners' textbook, so that the instructors can check them with ease.

extracellular matrix, umbilical cord, stem cells, biomimetics, phenotype, and blood
OBJECTIVE: To investigate the expansion of hematopoietic stem/progenitor cells (HSPCs) from umbilical cord blood using extracellular matrix (ECM) protein-coated three-dimensional hierarchical scaffolds. RESULTS: The expansion of HSPCs was evaluated through total nucleated cell (TNC) expansion, immuno-phenotypic analysis, and clonogenic ability. After 7 days of culture, three-dimensional cultures with fibronectin-coated scaffolds achieved the highest fold increase in TNCs (164 ± 6.9 fold) and the highest CD45⁺CD34⁺ (35 %) and CD34⁺CD38⁻ (32 %) ratios. CONCLUSION: Three-dimensional hierarchical scaffolds were coated with ECM protein to simulate a biomimetic environment or niche, and had a significant effect on the expansion potential of HSPCs without changing their phenotype.
In this paper we propose to explore different dedicated hardware solutions in terms of area-speed trade-offs for computing-oriented fuzzy logic systems in the algorithmic abstraction level that fulfil the application requirements applying high level synthesis techniques. The main benefits of this proposal are the capability of selecting the best implementation for any application not being tied down to a predefined architecture, the use of the required number of hardware units and the reduction of the design cycle time. The results obtained in the control of a maximum power point of a photovoltaic plant are presented as an example.

Chemically functionalized carbon nanotubes (CNTs) are promising materials for sensing of gases and volatile organic compounds. However, the poor solubility of carbon nanotubes hinders their chemical functionalization and the subsequent integration of these materials into devices. This manuscript describes a solvent-free procedure for rapid prototyping of selective chemiresistors from CNTs and graphite on the surface of paper. This procedure enables fabrication of functional gas sensors from commercially available starting materials in less than 15 min. The first step of this procedure involves the generation of solid composites of CNTs or graphite with small molecule selectors—designed to interact with specific classes of gaseous analytes—by solvent-free mechanical mixing in a ball mill and subsequent compression. The second step involves deposition of chemiresistive sensors by mechanical abrasion of these solid composites onto the surface of paper. Parallel fabrication of multiple chemiresistors from diverse composites rapidly generates cross-reactive arrays capable of sensing and differentiating gases and volatile organic compounds at part-per-million and part-per-thousand concentrations.

biological development, biodegradability, mechanical properties, cutting, stainless steel, and annealing
Biodegradable stents are considered to be a recent innovation, and their feasibility and applicability have been proven in recent years. Research in this area has focused on materials development and biological studies, rather than on how to transform the developed biodegradable materials into the stent itself. Currently available stent technology, the laser cutting-based process, might be adapted to fabricate biodegradable stents. In this work, the fabrication, characterization and testing of biodegradable Fe–Mn stents are described. A standard process for fabricating and testing stainless steel 316L stents was referred to. The influence of process parameters on the physical, metallurgical and mechanical properties of the stents, and the quality of the produced stents, were investigated. It was found that some steps of the standard process such as laser cutting can be directly applied, but changes to parameters are needed for annealing, and alternatives are needed to replace electropolishing.
