Abstract Background: Analysis of cerebrospinal fluid (CSF) parameters helps clinicians identify patients with central nervous system (CNS) disease. In previous literature, reference values for CSF may be based on patients who were not truly healthy, other species, or outdated information. In the present study, we performed lumbar puncture in patients requiring spinal anesthesia by a reasonable indication to evaluate CSF parameters in healthy adults. Methods: All patients between the ages of 20 and 70 years scheduled for elective orthopedic or urologic surgery requiring spinal anesthesia were enrolled in this study. We measured electrolytes and gas tension analysis in CSF and whole blood samples in adult humans. Results: A total of 28 patients were included with an average age of 44.2 years. The pH of blood and CSF were both neutral, but it was slightly lower in blood. The concentration of Na+ in blood was slightly lower compared with that in CSF. There were significantly higher levels of K+ and Ca2+ in the blood compared with CSF. Significantly lower levels of Cl- and Mg2+ in the blood were observed compared with CSF. The glucose level of CSF was about half of that in blood. Conclusions: We provided updated reference values for various solutes in blood and CSF in adults. Although normal CSF constituents are quite similar to that of blood, there is still a small difference in normal values between them. Analysis of CSF parameters and relevant paired blood samples is highly informative, helping clinicians diagnose a variety of CNS diseases. Trial registration: This present study was approved by the Institutional Review Board of Chang Gung Medical Foundation, Taiwan (approval number: 201600122A3), and is registered under Clinical Trials Registry (ClinicalTrials.gov Identifier: NCT03725709).

Abstract While post-migrant generation Moroccans from Europe often are able to converse competently enough in Moroccan languages to bargain in shops during visits to Morocco, many report that they are not given the ‘local’, ‘right’ prices because they are ‘smelled’ as outsiders. During fieldwork following these diasporic visitors in Morocco, several participants strategically shopped for goods with a ‘local’ friend or family member who might negotiate on their behalf for the ‘right’ price. This strategy was seen as a way to circumvent or ameliorate the ways the diasporic client might be negatively categorized as an outsider, especially in terms of his or her language use. Yet, examining these events in recorded detail indicates that diasporic clients are often bargaining for themselves as competent speakers, but are sometimes not able to skillfully bargain politely. In these moments, proxy bargainers intervene when debate and tension increases during bargaining and diasporic visitors do not adequately perform politeness – specifically by deploying religious speech – to soften and minimize tension. Analysis of these interactions indicates how diasporic branching of linguistic practice contrasts communicative skills of mobile populations with subtle, place-based competences, and how the mismatch between these can negatively mark diasporic visitors.

A Cable-Driven Robotic Arm (CDRA) possesses a number of advantages over the conventional articulated robotic arms, such as lightweight mechanical structure, high payload, fault tolerance, and most importantly, safe manipulation in the human environment. As such, a mobile manipulator that consists of a mobile base and a CDRA can be a promising assistive robot for the aging or disabled people to perform necessary tasks in their daily life. For such applications, a CDRA is a dexterous manipulator that consists of a number of cable-driven joint modules. In this chapter, a modular design concept is employed in order to simplify design, analysis, and control of CDRA to a manageable level. In particular, a 2-DOF cable-driven joint module is proposed as the basic building block of a CDRA. The critical design analysis issues pertaining to the kinematics analysis, tension analysis, and workspace-based design optimization of the 2-DOF cable-driven joint module are discussed. As a modular CDRA can be constructed into various configurations, a configuration-independent kinematic modeling approach based on the Product-of-Exponentials (POE) formula is proposed. The effectiveness of the proposed design analysis algorithms are demonstrated through simulation examples.

In this work, we report the synthesis of eco-friendly detergent from crude palm oil and titania. Crude palm oil was converted into methyl ester sulfonate through esterification, transesterification and followed by sulfonation process. As-produced methyl ester sulfonate was characterized with Fourier transformed infrared spectroscopy (FTIR), gas chromatography-mass spectroscopy (GC-MS), liquid chromatography mass spectroscopy (LCMS) and surface tension analysis. Detergents were synthesized by dispersing titania nanoparticles into methyl ester sulfonate solution, forming a nanofluid. Stability and detergency of the nanofluidic detergents were then evaluated. The results showed that the nanofluid detergents were stable in the presence of 0.1 wt % titania and the photocatalytic activity of titania nanoparticles improved the ability of nanofluidic detergents to remove dirt as well as degrading the surfactant residues in the laundry waste stream.

Abstract In the US Pacific Northwest and other mountainous regions, cable yarding using portable steel towers is a common harvesting system in steep terrain. These systems are expensive and can be unsafe if improperly rigged. For both economic and safety considerations, configurations are used that ensure that the system can sustain the forces applied during yarding operations. We present a computer-based application, GuylinePC, for evaluating the guyline and anchor loads resulting from an applied load. Our model extends the usability and scope of a model previously developed by other researchers. Specifically we (1) provide a more modern graphical user interface, (2) use optimization methods to determine equilibrium states, and (3) illustrate the capability of the program to be used in design. We briefly discuss the analytical model and software application and present a design problem. The program is intended to improve a forest engineer's understanding of cable yarding systems.
