factor of Gram-negative bacteria. It is a complex, structurally het- erogeneous mixture due to variations in number, type, and position of its simplest units: fatty acids and monosaccharides. Thus, LPS structural characterization by traditional mass spectrometry (MS) methods is challenging. Here, we describe the benefits of field asymmetric ion mobility spectrometry (FAIMS) for analysis of intact R-type lipopolysaccharide complex mixture (lipooligo- saccharide; LOS). Structural characterization was performed using Escherichia coli J5 (Rc mutant) LOS, a TLR4 agonist widely used in glycoconjugate vaccine research. FAIMS gas phase fractionation improved the (S/N) ratio and number of detected LOS species. Additionally, FAIMS allowed the separation of overlapping isobars facilitating their tandem MS characterization and un- equivocal structural assignments. In addition to FAIMS gas phase fractionation benefits, extra sorting of the structurally related LOS molecules was further accomplished using Kendrick mass defect (KMD) plots. Notably, a custom KMD base unit of [Na-H] created a highly organized KMD plot that allowed identification of interesting and novel structural differences across the different LOS ion families, i.e., ions with different acylation degrees, oligosaccharides composition, and chemical modifications. Defining the composition of a single LOS ion by tandem MS along with the organized KMD plot structural network was sufficient to deduce the composition of 181 LOS species out of 321 species present in the mixture. The combination of FAIMS and KMD plots allowed in-depth characterization of the complex LOS mixture and uncovered a wealth of novel information about its structural variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipopolysaccharide" title="lipopolysaccharide">lipopolysaccharide</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20mobility%20MS" title=" ion mobility MS"> ion mobility MS</a>, <a href="https://publications.waset.org/abstracts/search?q=Kendrick%20mass%20defect" title=" Kendrick mass defect"> Kendrick mass defect</a>, <a href="https://publications.waset.org/abstracts/search?q=Tandem%20mass%20spectrometry" title=" Tandem mass spectrometry"> Tandem mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/173086/structural-elucidation-of-intact-rough-type-lipopolysaccharides-using-field-asymmetric-ion-mobility-spectrometry-and-kendrick-mass-defect-plots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173086.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9859</span> Urinary Volatile Organic Compound Testing in Fast-Track Patients with Suspected Colorectal Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Godwin%20Dennison">Godwin Dennison</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20E.%20Boulind"> C.

A large number of invasive tests are presently performed for reassurance. We investigated the feasibility of urinary volatile organic compound (VOC) testing as a potential triage tool in patients fast-tracked for assessment for possible CRC. Methods: A prospective, multi-centre, observational feasibility study was performed across three sites. Patients referred on NHS fast-track pathways for potential CRC provided a urine sample which underwent Gas Chromatography Mass Spectrometry (GC-MS), Field Asymmetric Ion Mobility Spectrometry (FAIMS) and Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) analysis. Patients underwent colonoscopy and/or CT colonography and were grouped as either CRC, adenomatous polyp(s), or controls to explore the diagnostic accuracy of VOC output data supported by an artificial neural network (ANN) model. Results: 558 patients participated with 23 (4.1%) CRC diagnosed. 59% of colonoscopies and 86% of CT colonographies showed no abnormalities. Urinary VOC testing was feasible, acceptable to patients, and applicable within the clinical fast track pathway. GC-MS showed the highest clinical utility for CRC and polyp detection vs. controls (sensitivity=0.878, specificity=0.882, AUROC=0.884). Conclusion: Urinary VOC testing and analysis are feasible within NHS fast-track CRC pathways. Clinically meaningful differences between patients with cancer, polyps, or no pathology were identified therefore suggesting VOC analysis may have future utility as a triage tool.

The present work describes estimation of field dependent mobility (FDM) parameters and the threshold voltage of an OTFT using a simple, easy to fabricate two terminal asymmetric capacitive test structure using admittance measurements. Conventionally, transfer characteristics are used to estimate the threshold voltage in an OTFT with field independent mobility (FIDM). Yet, this technique breaks down to give accurate results for devices with high contact resistance and having field dependent mobility. In this work, a new technique is presented for characterization of long channel organic capacitor (LCOC). The proposed technique helps in the accurate estimation of mobility enhancement factor (γ), the threshold voltage (V_th) and band mobility (µ₀) using capacitance-voltage (C-V) measurement in OTFT. This technique also helps to get rid of making short channel OTFT or metal-insulator-metal (MIM) structures for making C-V measurements. To understand the behavior of devices and ease of analysis, transmission line compact model is developed. The 2-D numerical simulation was carried out to illustrate the correctness of the model. Results show that proposed technique estimates device parameters accurately even in the presence of contact resistance and field dependent mobility. Pentacene/Poly (4-vinyl phenol) based top contact bottom-gate OTFT’s are fabricated to illustrate the operation and advantages of the proposed technique. Small signal of frequency varying from 1 kHz to 5 kHz and gate potential ranging from +40 V to -40 V have been applied to the devices for measurement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacitance" title="capacitance">capacitance</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility" title=" mobility"> mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=organic" title=" organic"> organic</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film%20transistor" title=" thin film transistor"> thin film transistor</a> </p> <a href="https://publications.waset.org/abstracts/94974/estimation-of-mobility-parameters-and-threshold-voltage-of-an-organic-thin-film-transistor-using-an-asymmetric-capacitive-test-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94974.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9857</span> Saturation Misbehavior and Field Activation of the Mobility in Polymer-Based OTFTs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Giraudet">L.

Experimental evidence of the field activation of the mobility is given for disordered semiconductor based TFTs, when reducing the gate length. Saturation misbehavior is observed simultaneously. Advanced transport models have been implemented in a quasi-2D numerical TFT simulation software. From the numerical simulations it is clearly established that field activation of the mobility alone cannot explain the saturation misbehavior. Evidence is given that high longitudinal field gradient at the drain end of the channel is responsible for an excess charge accumulation, preventing saturation. The two combined effects allow reproducing the experimental output characteristics of short channel TFTs, with S-shaped characteristics and saturation failure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobility%20field%20activation" title="mobility field activation">mobility field activation</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=OTFT" title=" OTFT"> OTFT</a>, <a href="https://publications.waset.org/abstracts/search?q=saturation%20failure" title=" saturation failure "> saturation failure </a> </p> <a href="https://publications.waset.org/abstracts/19411/saturation-misbehavior-and-field-activation-of-the-mobility-in-polymer-based-otfts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19411.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">520</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9856</span> Development of Ultrasounf Probe Holder for Automatic Scanning Asymmetric Reflector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabilah%20Ibrahim">Nabilah Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Mohd%20Zaini"> Hafiz Mohd Zaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Wan%20Fatin%20Liyana%20Mutalib"> Wan Fatin Liyana Mutalib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ultrasound equipment or machine is capable to scan in two dimensional (2D) areas.

Asymmetric rolling is a very effective way to create ultrafine-grained structures of metals and alloys. Since the asymmetric rolling is a continuous process, it has great potential for industrial production of ultrafine-grained structure sheets. Basic principles of asymmetric rolling are described in detail in scientific literature. In this work finite element modeling of asymmetric rolling and metal forming processes in multiroll gauge was performed. Parameters of the processes which allow achieving significant values of shear strain were defined.

With the help of computational and graphical results the effects of Brownian motion, thermophoresis, Dufour, Soret, and Grashof numbers (thermal, concentration, nanoparticles) on peristaltic flow patterns with double-diffusive convection are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofluid%20particles" title="nanofluid particles">nanofluid particles</a>, <a href="https://publications.waset.org/abstracts/search?q=peristaltic%20flow" title=" peristaltic flow"> peristaltic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20fluid" title=" Jeffrey fluid"> Jeffrey fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20channel" title=" asymmetric channel"> asymmetric channel</a>, <a href="https://publications.waset.org/abstracts/search?q=different%20waveforms" title=" different waveforms"> different waveforms</a> </p> <a href="https://publications.waset.org/abstracts/71169/peristaltic-transport-of-a-jeffrey-fluid-with-double-diffusive-convection-in-nanofluids-in-the-presence-of-inclined-magnetic-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71169.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">381</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9853</span> Asymmetric Information and Composition of Capital Inflows: Stock Market Microstructure Analysis of Asia Pacific Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farid%20Habibi%20Tanha">Farid Habibi Tanha</a>, <a href="https://publications.waset.org/abstracts/search?q=Hawati%20Janor"> Hawati Janor</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Jahanbazi"> Mojtaba Jahanbazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to examine the effect of asymmetric information on the composition of capital inflows. This study uses the stock market microstructure to capture the asymmetric information. Such an approach allows one to capture the level and extent of the asymmetric information from a firm’s perspective. This study focuses on the two-dimensional measure of the market microstructure in capturing asymmetric information. The composition of capital inflows is measured by running six models simultaneously. By employing the panel data technique, the main finding of this research shows an increase in the asymmetric information of the stock market, in any of the two dimensions of width and depth. This leads to the reduction of foreign investments in both forms of foreign portfolio investment (FPI) and foreign direct investment (FDI), while the reduction in FPI is higher than that of the FDI. The significant effect of asymmetric information on capital inflows implicitly suggests for policymakers to control the changes of foreign capital inflows through transparency in the level of the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capital%20flows%20composition" title="capital flows composition">capital flows composition</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20information" title=" asymmetric information"> asymmetric information</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20market%20microstructure" title=" stock market microstructure"> stock market microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20portfolio%20investment" title=" foreign portfolio investment"> foreign portfolio investment</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20direct%20investment" title=" foreign direct investment "> foreign direct investment </a> </p> <a href="https://publications.waset.org/abstracts/28871/asymmetric-information-and-composition-of-capital-inflows-stock-market-microstructure-analysis-of-asia-pacific-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28871.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">364</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9852</span> Nonreciprocal Optical Effects in Plasmonic Nanoparticle Aggregates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ward%20Brullot">Ward Brullot</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Verbiest"> Thierry Verbiest</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nonreciprocal optical effects, such as Faraday rotation or magnetic circular dichroism, are very useful both for fundamental studies as for applications such as magnetic field sensors or optical isolators. In this study, we developed layer-by-layer deposited 20nm thick plasmonic nanoparticle aggregates consisting of gold, silver and magnetite nanoparticles that show broadband nonreciprocal asymmetric transmission. As such, the optical transmittance, or absorbance, depends on the direction of light propagation in the material, which means that looking from one direction or the other, more or less light passes through the sample. Theoretical analysis showed that strong electric quadrupole fields, which are electric field gradients, occur in the aggregates and that these quadrupole fields are responsible for the observed asymmetric transmission and the nonreciprocity of the effect. Apart from nonreciprocal asymmetric transmission, also other effects such as, but not limited to, optical rotation, circular dichroism or nonlinear optical responses were measured in the plasmonic nanoparticle aggregates and the influences of the intense electric quadrupole fields determined. In conclusion, the presence of strong electric quadrupole fields make the developed plasmonic nanoparticle aggregates ideal candidates for the study and application of various nonreciprocal optical effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20transmission" title="asymmetric transmission">asymmetric transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20quadrupoles" title=" electric quadrupoles"> electric quadrupoles</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle%20aggregates" title=" nanoparticle aggregates"> nanoparticle aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=nonreciprocity" title=" nonreciprocity"> nonreciprocity</a> </p> <a href="https://publications.waset.org/abstracts/33791/nonreciprocal-optical-effects-in-plasmonic-nanoparticle-aggregates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33791.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">424</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9851</span> Asymmetric Warfare: Exploratory Study of the Implicit Defense Strategy of the People's Republic of China in 2012-2016</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Victoria%20Alvarez%20Maga%C3%B1ini">María Victoria Alvarez Magañini</a>, <a href="https://publications.waset.org/abstracts/search?q=Lautaro%20Nahuel%20Rubbi"> Lautaro Nahuel Rubbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to different theories, the hegemonic war between the United States and the People's Republic of China seems to be imminent. However, nowadays, it is clear that China's conventional military capacity is inferior to that of the United States. Nevertheless, the conditions that in the past were considered to be an indicator of validity in asymmetrical warfare, at present, in a possible asymmetric war scenario, are no longer considered to be taken as such. The military capacity is not the only concept that represents the main indicator of victory. The organisation and the use of forces are also an essential part of it. The present paper aims to analyze the Chinese Defense Strategy in relation to the concept of asymmetric warfare in the face of a possible war with the United States. The starting point will be developed on the basis of application of the theory which corresponds to the concept aforementioned making focus on recent developments of the People’s Republic of China in the field of non-conventional defense. A comparative analysis of the conventional forces of both powers/countries will also be carried out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20warfare" title="asymmetric warfare">asymmetric warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a>, <a href="https://publications.waset.org/abstracts/search?q=United%20States" title=" United States"> United States</a>, <a href="https://publications.waset.org/abstracts/search?q=hegemonic%20warfare" title=" hegemonic warfare"> hegemonic warfare</a> </p> <a href="https://publications.waset.org/abstracts/75287/asymmetric-warfare-exploratory-study-of-the-implicit-defense-strategy-of-the-peoples-republic-of-china-in-2012-2016" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75287.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9850</span> VANETs Geographic Routing Protocols: A survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Karimi">Ramin Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of common highly mobile wireless ad hoc networks is Vehicular Ad Hoc Networks. Hence routing in vehicular ad hoc network (VANET) has attracted much attention during the last few years. VANET is characterized by its high mobility of nodes and specific topology patterns. Moreover these networks encounter a significant loss rate and a very short duration of communication. In vehicular ad hoc networks, one of challenging is routing of data due to high speed mobility and changing topology of vehicles. Geographic routing protocols are becoming popular due to advancement and availability of GPS devices. Delay Tolerant Networks (DTNs) are a class of networks that enable communication where connectivity issues like sparse connectivity, intermittent connectivity; high latency, long delay, high error rates, asymmetric data rate, and even no end-to-end connectivity exist. In this paper, we review the existing Geographic Routing Protocols for VANETs and also provide a qualitative comparison of them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicular%20ad%20hoc%20networks" title="vehicular ad hoc networks">vehicular ad hoc networks</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility" title=" mobility"> mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20routing" title=" geographic routing"> geographic routing</a>, <a href="https://publications.waset.org/abstracts/search?q=delay%20tolerant%20networks" title=" delay tolerant networks"> delay tolerant networks</a> </p> <a href="https://publications.waset.org/abstracts/34821/vanets-geographic-routing-protocols-a-survey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34821.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">520</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9849</span> Fast-Forward Problem in Asymmetric Double-Well Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iwan%20Setiawan">Iwan Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bobby%20Eka%20Gunara"> Bobby Eka Gunara</a>, <a href="https://publications.waset.org/abstracts/search?q=Katshuhiro%20Nakamura"> Katshuhiro Nakamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The theory to accelerate system on quantum dynamics has been constructed to get the desired wave function on shorter time.

The continuously developing segment involves a variety of affected issues such as public and economic sectors. Beside the changes in mobility the state of environment had also changed in the last period. Alternative mobility as a separate category and the idea of its widespread appliance is such a new field that needs to be studied deeper. Alternative mobility implies finding new types of propulsion, using innovative kinds of power and energy resources, revolutionizing the approach to vehicular control. Including new resources and excluding others has such a complex effect which cannot be unequivocally confirmed by today’s scientific achievements. Changes in specific parameters will most likely reduce the environmental impacts, however, the production of new substances or even their subtraction of the system will cause probably energy deficit as well. The aim of this research is to elaborate the environmental impact matrix of alternative mobility and cognize the factors that are yet unknown, analyse them, look for alternative solutions and conclude all the above in a coherent system. In order to this, we analyse it with a method called ‘the system of systems (SoS) method’ to model the effects and the dynamics of the system. A part of the research process is to examine its impacts on the environment, and to decide whether the newly developed versions of alternative mobility are affecting the environmental state. As a final result, a complex approach will be used which can supplement the current scientific studies. By using the SoS approach, we create a framework of reference containing elements in which we examine the interactions as well. In such a way, a flexible and modular model can be established which supports the prioritizing of effects and the deeper analysis of the complex system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20mobility" title=" alternative mobility"> alternative mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20model" title=" complex model"> complex model</a>, <a href="https://publications.waset.org/abstracts/search?q=element%20analysis" title=" element analysis"> element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multidimensional%20map" title=" multidimensional map"> multidimensional map</a> </p> <a href="https://publications.waset.org/abstracts/57727/multidimensional-approach-to-analyse-the-environmental-impacts-of-mobility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57727.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">324</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9846</span> Mobility Management via Software Defined Networks (SDN) in Vehicular Ad Hoc Networks (VANETs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bilal%20Haider">Bilal Haider</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Aadil"> Farhan Aadil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Vehicular Ad hoc Network (VANET) provides various services to end-users traveling on the road at high speeds. However, this high-speed mobility of mobile nodes can cause frequent service disruptions. Various mobility management protocols exist for managing node mobility, but due to their centralized nature, they tend to suffer in the VANET environment. In this research, we proposed a distributed mobility management protocol using software-defined networks (SDN) for VANETs. Instead of relying on a centralized mobility anchor, the mobility functionality is distributed at multiple infrastructural nodes. The protocol is based on the classical Proxy Mobile IP version 6 (PMIPv6). It is evident from simulation results that this work has improved the network performance with respect to nodes throughput, delay, and packet loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SDN" title="SDN">SDN</a>, <a href="https://publications.waset.org/abstracts/search?q=VANET" title=" VANET"> VANET</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility%20management" title=" mobility management"> mobility management</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/147701/mobility-management-via-software-defined-networks-sdn-in-vehicular-ad-hoc-networks-vanets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147701.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9845</span> Influence of UV/Ozone Treatment on the Electrical Performance of Polystyrene Buffered Pentacene-Based OFETs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lin%20Gong">Lin Gong</a>, <a href="https://publications.waset.org/abstracts/search?q=Holger%20G%C3%B6bel"> Holger Göbel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, we have investigated the influence of UV/ozone treatment on pentacene-based organic field effect transistors (OFETs) with a bilayer gate dielectric. The OFETs for this study were fabricated on heavily n-doped Si substrates with a thermally deposited SiO2 dielectric layer (300nm). On the SiO2 dielectric a very thin (≈ 15nm) buffer layer of polystyrene (PS) was first spin-coated and then treated by UV/ozone to modify the surface prior to the deposition of pentacene. We found out that by extending the UV/ozone treatment time the threshold voltage of the OFETs was monotonically shifted towards positive values, whereas the field effect mobility first decreased but eventually reached a stable value after a treatment time of approximately thirty seconds. Since the field effect mobility of the UV/ozone treated bilayer OFETs was found to be higher than the value of a comparable transistor with a single layer dielectric, we propose that the bilayer (SiO2/PS) structure can be used to shift the threshold voltage to a desired value without sacrificing field effect mobility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer%20layer" title="buffer layer">buffer layer</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20field%20effect%20transistors" title=" organic field effect transistors"> organic field effect transistors</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20voltage" title=" threshold voltage"> threshold voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%2Fozone%20treatment" title=" UV/ozone treatment"> UV/ozone treatment</a> </p> <a href="https://publications.waset.org/abstracts/41415/influence-of-uvozone-treatment-on-the-electrical-performance-of-polystyrene-buffered-pentacene-based-ofets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41415.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9844</span> Computer Software for Calculating Electron Mobility of Semiconductors Compounds; Case Study for N-Gan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emad%20A.%20Ahmed">Emad A.

In the past, asymmetric powers of errors in the conditionally heteroskedastic models have been used to capture this effect. Our model is using the gamma difference representation of the generalized Laplace distributions that efficiently models the asymmetry. It has one additional natural parameter, the shape, that is used instead of power in the asymmetric power models to capture the strength of a long-lasting effect of shocks. Some fundamental properties of the model are provided including the formula for covariances and an explicit form for the conditional distribution of 'bad' and 'good' news processes given the past the property that is important for the statistical fitting of the model.

Because of their improved electrical conductivity and narrower band gap, transition metal selenide-based nanostructures have piqued the interest of many researchers in this field. Based on this concept, we present a simple anion exchange hydrothermal synthesis method for synthesizing manganese and nickel based selenide (Mn/NiSe2) nanostructure for use in all-solid-state asymmetric supercapacitors. According to the comprehensive physicochemical characterizations, the material has lowly crystalline properties, a distinct porous microstructure, and a significant bonding contact between the metal and the selenium. The electrochemical investigations of the Mn/NiSe2 electrode material revealed supercapacitive charge discharge properties, excellent electro-kinetic reversibility, and minimal charge transfer resistance (Rct). Furthermore, the all-solid-state asymmetric supercapacitor device assembled using Mn/NiSe2 as positive electrode, nitrogen doped reduced graphene oxide (N-rGO) as negative electrode, and PVA-KOH gel as electrolyte/separator exhibit good redox behaviour, excellent charge-discharge properties with negligible voltage (IR) drop, and lower impedance characteristics. The solid state asymmetric supercapacitor device (Mn/NiSe2||N-rGO) demonstrated the power density of ultra-capacitors and the energy density of rechargeable batteries. Conclusively, the Mn/NiSe2 has been proposed as a potential outstanding electrode material for the next generation of all-solid-state asymmetric supercapacitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anion%20exchange" title="anion exchange">anion exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20supercapacitor" title=" asymmetric supercapacitor"> asymmetric supercapacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitive%20charge-discharge" title=" supercapacitive charge-discharge"> supercapacitive charge-discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20drop" title=" voltage drop"> voltage drop</a> </p> <a href="https://publications.waset.org/abstracts/168493/hierarchical-manganese-and-nickel-selenide-based-ultra-efficient-electrode-material-for-all-solid-state-asymmetric-supercapacitors-with-extended-energy-efficacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168493.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9840</span> Near Infrared Spectrometry to Determine the Quality of Milk, Experimental Design Setup and Chemometrics: Review </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meghana%20Shankara">Meghana Shankara</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyadarshini%20Natarajan"> Priyadarshini Natarajan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Infrared (IR) spectroscopy has revolutionized the way we look at materials around us. Unraveling the pattern in the molecular spectra of materials to analyze the composition and properties of it has been one of the most interesting challenges in modern science. Applications of the IR spectrometry are numerous in the field’s pharmaceuticals, health, food and nutrition, oils, agriculture, construction, polymers, beverage, fabrics and much more limited only by the curiosity of the people. Near Infrared (NIR) spectrometry is applied robustly in analyzing the solids and liquid substances because of its non-destructive analysis method. In this paper, we have reviewed the application of NIR spectrometry in milk quality analysis and have presented the modes of measurement applied in NIRS measurement setup, Design of Experiment (DoE), classification/quantification algorithms used in the case of milk composition prediction like Fat%, Protein%, Lactose%, Solids Not Fat (SNF%) along with different approaches for adulterant identification.

Although infrared photodetectors based on layered 2D narrow bandgap semiconductors have shown admirable advantages compared with those based on conventional compounds, which typically suffer from expensive cryogenic operations, it is still urgent to develop a simple but effective strategy to further reduce the dark current. Herein, a tellurium (Te) based infrared photodetector is reported with a specifically designed asymmetric electrical contact area. The deliberately introduced asymmetric electrical contact raises the electric field intensity difference in the Te channel near the drain and the source electrodes, resulting in spontaneous asymmetric carrier diffusion under global infrared light illumination under zero bias. Specifically, the Te-based photodetector presents promising detector performance at room temperature, including a low dark current of≈1 nA, an ultrahigh photocurrent/dark current ratio of 1.57×10⁴, a high specific detectivity (D*) of 3.24×10⁹ Jones, and relatively fast response speed of ≈720 μs at zero bias. The results prove that the simple design of asymmetric electrical contact areas can provide a promising solution to high-performance 2D semiconductor-based infrared photodetectors working at room temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetrical%20contact" title="asymmetrical contact">asymmetrical contact</a>, <a href="https://publications.waset.org/abstracts/search?q=tellurium" title=" tellurium"> tellurium</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20current" title=" dark current"> dark current</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20photodetector" title=" infrared photodetector"> infrared photodetector</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/185792/asymmetrically-contacted-tellurium-short-wave-infrared-photodetector-with-low-dark-current-and-high-sensitivity-at-room-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185792.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">51</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9837</span> Erasmus+ Program in Vocational Education: Effects of European International Mobility in Portuguese Vocational Schools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Carlos%20Bronze">José Carlos Bronze</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlinda%20Leite"> Carlinda Leite</a>, <a href="https://publications.waset.org/abstracts/search?q=Ang%C3%A9lica%20Monteiro"> Angélica Monteiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The creation of the Erasmus Program in 1987 represented a milestone in promoting and funding international mobility in higher education in Europe. Its effects were so significant that they influenced the creation of the European Higher Education Area through the Bologna Process and ensured the program’s continuation and maintenance. Over the last decades, the escalating figures of participants and funds instigated significant scientific studies on the program's effects on higher education. More recently, in 2014, the program was renamed “Erasmus+” when it expanded into other fields of education, namely Vocational Education and Training (VET). Despite being now running in this field of education for a decade (2014-2024), its effects on VET remain less studied and less known, while the higher education field keeps attracting researchers’ attention. Given this gap, it becomes relevant to study the effects of E+ on VET, particularly in the priority domains of the Program: “Inclusion and Diversity,” “Participation in Democratic Life, Common Values and Civic Engagement,” “Environment and Fight Against Climate Change,” and “Digital Transformation.” This latter has been recently emphasized due to the COVID-19 pandemic that forced the so-called emergency remote teaching, leading schools to quickly transform and adapt to a new reality regardless of the preparedness levels of teachers and students. Together with the remaining E+ priorities, they directly relate to an emancipatory perspective of education sustained in soft skills such as critical thinking, intercultural awareness, autonomy, active citizenship, teamwork, and problem-solving, among others. Based on this situation, it is relevant to know the effects of E+ on the VET field, namely questioning how international mobility instigates digitalization processes and supports emancipatory queries therein. As an education field that more directly connects to hard skills and an instrumental approach oriented to the labor market’s needs, a study was conducted to determine the effects of international mobility on developing digital literacy and soft skills in the VET field. In methodological terms, the study used semi-structured interviews with teaching and non-teaching staff from three VET schools who are strongly active in the E+ Program. The interviewees were three headmasters, four mobility project managers, and eight teachers experienced in international mobility. The data was subjected to qualitative content analysis using the NVivo 14 application. The results show that E+ international mobility promotes and facilitates the use of digital technologies as a pedagogical resource at VET schools and enhances and generates students’ soft skills. In conclusion, E+ mobility in the VET field supports adopting the program’s priorities by increasing the teachers’ knowledge and use of digital resources and amplifying and generating participants’ soft skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erasmus%20international%20mobility" title="Erasmus international mobility">Erasmus international mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20literacy" title=" digital literacy"> digital literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20skills" title=" soft skills"> soft skills</a>, <a href="https://publications.waset.org/abstracts/search?q=vocational%20education%20and%20training" title=" vocational education and training"> vocational education and training</a> </p> <a href="https://publications.waset.org/abstracts/187577/erasmus-program-in-vocational-education-effects-of-european-international-mobility-in-portuguese-vocational-schools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187577.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">32</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9836</span> Chiral Diphosphine Ligands and Their Transition Metal Diphosphine Complexes in Asymmetric Catalysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shannen%20Lorraine">Shannen Lorraine</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Maragh"> Paul Maragh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tara%20Dasgupta"> Tara Dasgupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamaluddin%20Abdur-Rashid"> Kamaluddin Abdur-Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> (R)-(4,4',6,6'-tetramethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (R-Ph-Garphos), and (S)-(4,4',6,6'-tetramethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (S-Ph-Garphos) are novel, nucleophilic, chiral atropisomeric ligands. The research explored the synthesis of chiral transition metal complexes containing these ligands and their applications in various asymmetric catalytic transformations. Herein, the transition metal complexes having ruthenium(II), rhodium(I) and iridium(I) metal centres will be discussed. These are air stable complexes and were characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. Currently, there is an emphasis on 'greener' catalysts and the need for 'green' solvents in asymmetric catalysis. As such, the Ph-Garphos ligands were demethylated thereby introducing hydroxyl moieties unto the ligand scaffold. The facile tunability of the biaryl diphosphines led to the preparation of the (R)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (R-Ph-Garphos-OH), and (S)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (S-Ph-Garphos-OH) ligands. These were successfully characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. The use of the Ph-Garphos and Ph-Garphos-OH ligands and their transition metal complexes in asymmetric hydrogenations will be reported.

This makes the provision of infrastructure and network of mobility an effective element in the urban conservation. Sustainable urban conservation projects consider the high density of activities, the need for a good quality access system to the transit system, and the importance of the configuration of the mobility network by identifying the best way to connect the different districts of the urban area through a complex unique system that helps the synergic development to achieve a sustainable mobility system. A sustainable urban mobility is a key factor in maintaining the integrity between socio-cultural aspects and functional aspects. This paper illustrates the mobility aspects, mobility problems in historic districts, and the needs of the mobility systems in the first part. The second part is a practical analysis for different mobility plans. It is challenging to find innovative and creative conservation solutions fitting modern uses and needs without risking the loss of inherited built resources. Urban mobility management is becoming an essential and challenging issue in the urban conservation projects. Depending on literature review and practical analysis, this paper tries to define and clarify the guidelines for mobility management in historic districts as a key element in sustainability of urban conservation and development projects. Such rules and principles could control the conflict between the socio–cultural and economic activities, and the different needs for mobility in these districts in a sustainable way. The practical analysis includes a comparison between mobility plans which have been implemented in four different cities; Freiburg in Germany, Zurich in Switzerland and Bray Town in Ireland. This paper concludes with a matrix of guidelines that considers both principles of sustainability and livability factors in urban historic districts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20mobility" title="sustainable mobility">sustainable mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20mobility" title=" urban mobility"> urban mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility%20management" title=" mobility management"> mobility management</a>, <a href="https://publications.waset.org/abstracts/search?q=historic%20districts" title=" historic districts"> historic districts</a> </p> <a href="https://publications.waset.org/abstracts/94329/guidelines-for-sustainable-urban-mobility-in-historic-districts-from-international-experiences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9834</span> Systematic Literature Review and Bibliometric Analysis of Interorganizational Employee Mobility Determinants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iva%20Zdrili%C4%87">Iva Zdrilić</a>, <a href="https://publications.waset.org/abstracts/search?q=Petra%20Do%C5%A1enovi%C4%87%20Bon%C4%8Da"> Petra Došenović Bonča</a>, <a href="https://publications.waset.org/abstracts/search?q=Darija%20Aleksi%C4%87"> Darija Aleksić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the boundaryless career, with its emphasis on cross-employer movements, was introduced as a new paradigm of career development, inter-organizational employee mobility has been increasing. Although this phenomenon may have positive implications for individual careers and destination organizations, the consequences for the source organizations losing workers are less clear. The aim of this paper is thus to develop a comprehensive typology of possible inter-organizational employee mobility determinants. Since the most common classification differentiates between mobility determinants at different levels (i.e., economic, organizational, and individual), this paper focuses on building a comprehensive multi-level typology of inter-organizational mobility determinants across diverse sectors and industries. By using a structured literature review approach and bibliometric analysis, the paper reveals both intricate relationships between different mobility determinants and the complexity of inter-organizational networks and social ties. The latter appears as both a mobility determinant (at the organizational and individual level) and a mobility effect. Indeed, inter-organizational employee mobility leads to the formation of networks between source and destination organizations. These networks are practically based on the social ties between mobile employees and their colleagues and, in this way, they close the "inter-organizational employee mobility - inter-organizational network/ties" circle. The paper contributes to the career development literature by uncovering hitherto underexplored diverse determinants of intra- and inter-sectoral mobility as well as the conflicting results of the existing studies on some factors (e.g., inter-organizational networks and/or social ties) that appear both as a mobility determinant and a mobility effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter-organizational%20mobility" title="inter-organizational mobility">inter-organizational mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20ties" title=" social ties"> social ties</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-organizational%20network" title=" inter-organizational network"> inter-organizational network</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20transfer" title=" knowledge transfer"> knowledge transfer</a> </p> <a href="https://publications.waset.org/abstracts/150860/systematic-literature-review-and-bibliometric-analysis-of-interorganizational-employee-mobility-determinants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150860.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9833</span> Chiral Ruthenium Aminophosphine and Phosphine Iminopyridine Complexes: Synthesis and Application to Asymmetric Hydrogenation and Transfer Hydrogenation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Littlelet%20N.%20Scarlet">Littlelet N.

The unique combination of soft phosphorus (P) and hard nitrogen (N) centres affords a variety of transition metal complexes as potential pre-catalysts for synthetically useful reactions. Herein three ligand systems will be reported; two bidentate ligands - (S)-8-(diphenyl-phosphino)-1,2,3,4-tetrahydronaphthalen-1-amine, (S)THNANH2, and (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylethylamine, (RcSp)PPFNH2 - and a tridentate (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylimino-pyridine, (RcSp)PPFNNH2 ligand; the latter prepared from the condensation of selected ferrocene aminophosphines with pyridine-2-carboxaldehyde. Suitable combinations of these aminophosphine ligands with ruthenium precursors have afforded highly efficient systems for the asymmetric hydrogenation and transfer hydrogenation of selected ketones in 2-propanol. The Ru-(S)THNANH2 precatalyst was the most efficient in the asymmetric hydrogenation of selected ketones with 100% conversions within 4 hours at a catalyst loading of 0.1 mol%. The Ru-(RcSp)PPFNNH2 precatalyst was the most efficient in the asymmetric transfer hydrogenation of the ketones with conversions as high as 98% with 0.1 mol% catalyst. However, the enantioselectivities were generally low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aminophosphine" title="aminophosphine">aminophosphine</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20hydrogenation" title=" asymmetric hydrogenation"> asymmetric hydrogenation</a>, <a href="https://publications.waset.org/abstracts/search?q=homogeneous%20catalysis" title=" homogeneous catalysis"> homogeneous catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ruthenium%20%28II%29" title=" ruthenium (II)"> ruthenium (II)</a>, <a href="https://publications.waset.org/abstracts/search?q=transfer%20hydrogenation" title=" transfer hydrogenation"> transfer hydrogenation</a> </p> <a href="https://publications.waset.org/abstracts/70318/chiral-ruthenium-aminophosphine-and-phosphine-iminopyridine-complexes-synthesis-and-application-to-asymmetric-hydrogenation-and-transfer-hydrogenation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70318.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9832</span> Asymmetric Synthesis and Biological Study of Suberosanes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Kousara">Mohammad Kousara</a>, <a href="https://publications.waset.org/abstracts/search?q=Fran%C3%A7oise%20Dumas"> Françoise Dumas</a>, <a href="https://publications.waset.org/abstracts/search?q=Rama%20Ibrahim"> Rama Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%ABlle%20Dubois"> Joëlle Dubois</a>, <a href="https://publications.waset.org/abstracts/search?q=Jo%C3%ABl%20Raingeaud"> Joël Raingeaud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Suberosanes are a small group of marine natural sesquiterpenes discovered since 1996 by Boyd, Sheu and Qi from three gorgonians. Their skeleton was previously found in quadranes produced by the terrestrial fungus Aspergillus terreus. Up to date, eleven suberosanes are described from which (-)-suberosanone and (-)-suberosenol A are reaching the picomolar cytotoxicity level on human solid tumors cell lines. Due to their impressive cytotoxic properties and their limited availability, we undertook an asymmetric synthesis of the most active members of this family in order to get insight into their absolute configurations and their biological properties. The challenge of their synthesis is the regio- and stereoselective elaboration of the compact bridged tricyclic skeleton with up to five all adjacent asymmetric centers, including a central quaternary carbon one. Our strategy is based on an aza-ene-synthesis key step which is regio-and stereo-controlled by the choice of a chiral amine enantiomer. it approach is concise and flexible, the enantiopur ABC tricyclic intermediate that have been synthesized being the common precursor of suberosanes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=suberosanes" title="suberosanes">suberosanes</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20synthesis" title=" asymmetric synthesis"> asymmetric synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=sesquiterpenes" title=" sesquiterpenes"> sesquiterpenes</a>, <a href="https://publications.waset.org/abstracts/search?q=quadranes" title=" quadranes"> quadranes</a> </p> <a href="https://publications.waset.org/abstracts/172533/asymmetric-synthesis-and-biological-study-of-suberosanes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9831</span> Numerical Investigation Including Mobility Model for the Performances of Piezoresistive Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Beddiaf">Abdelaziz Beddiaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we present an analysis based on the study of mobility which is a very important electrical parameter of a piezoresistor and which is directly bound to the piezoresistivity effect in piezoresistive pressure sensors. We determine how the temperature affects mobility when the electric potential is applied. For this, a theoretical approach based on mobility in a p-type Silicon piezoresistor with that of a finite difference model for self-heating is developed. So, the evolution of mobility has been established versus time for different doping levels and with temperature rise provoked by self-heating using a numerical model combined with that of mobility. Furthermore, it has been calculated for some geometrical parameters of the sensor, such as membrane side length and thickness. Also, it is computed as a function of bias voltage. It was observed that mobility is strongly affected by the temperature rise induced by the applied potential when the sensor is actuated for a prolonged time as a consequence of drifting in the output response of the sensor. Finally, this work makes it possible to predict their temperature behavior due to self-heating and to improve this effect by optimizing the geometric properties of the device and by reducing the voltage source applied to the bridge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sensors" title="Sensors">Sensors</a>, <a
