In Low and Middle Income Countries (LMIC), resource constrain appears to be a major challenge in implementing the conventional QA system. We designed and implemented a modified LQAS model for QA of malaria parasite (MP) microscopy and RDT in a State Specialist Hospital (SSH) and a University Health Clinic (UHC) in Kano, Nigeria. The capacities of both facilities for MP microscopy and RDT were assessed before implementing a modified LQAS over a period of 3 months. Quality indicators comprising the qualities of blood film and staining, MP positivity rates, concordance rates, error rates (in terms of false positives and false negatives), sensitivity and specificity were monitored and evaluated. Seventy one percent (71%) of the basic requirements for malaria microscopy was available in both facilities, with the absence of certifies microscopists, SOPs and Quality Assurance mechanisms. A daily average of 16 to 32 blood samples were tested with a blood film staining quality of >70% recorded in both facilities. Using microscopy, the MP positivity rates were 50.46% and 19.44% in SSH and UHS respectively, while the MP positivity rates were 45.83% and 22.78% in SSH and UHS when RDT was used. Higher concordance rates of 88.90% and 93.98% were recorded in SSH and UHC respectively using microscopy, while lower rates of 74.07% and 80.58% in SSH and UHC were recorded when RDT was used. In both facilities, error rates were higher when RDT was used than with microscopy. Sensitivity and specificity were higher when microscopy was used (95% and 84% in SSH; 94% in UHC) than when RDT was used (72% and 76% in SSH; 78% and 81% in UHC). It could be feasible to implement an integrated QA model for MP microscopy and RDT using modified LQAS in Malaria Control Programmes in Low and Middle Income Countries that might have resource constrain for parasite-base diagnosis of malaria to justify ACT treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malaria" title="malaria">malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopy" title=" microscopy"> microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20assurance" title=" quality assurance"> quality assurance</a>, <a href="https://publications.waset.org/abstracts/search?q=RDT" title=" RDT"> RDT</a> </p> <a href="https://publications.waset.org/abstracts/44111/modified-lot-quality-assurance-sampling-lqas-model-for-quality-assessment-of-malaria-parasite-microscopy-and-rapid-diagnostic-tests-in-kano-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44111.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">222</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">26464</span> Mesoporous Material Nanofibers by Electrospinning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sh.%20Sohrabnezhad">Sh.

Andersen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A multimodal imaging system, combining spectrally resolved multiphoton microscopy (MPM) and optical coherence microscopy (OCM) is demonstrated. MPM and OCM are commonly integrated into multimodal imaging platforms to combine functional and morphological information. The MPM signals, such as two-photon fluorescence emission (TPFE) and signals created by second harmonic generation (SHG) are biomarkers which exhibit information on functional biological features such as the ratio of pyridine nucleotide (NAD(P)H) and flavin adenine dinucleotide (FAD) in the classification of cancerous tissue. While the spectrally resolved imaging allows for the study of biomarkers, using a spectrometer as a detector limits the imaging speed of the system significantly. To overcome those limitations, an OCM setup was added to the system, which allows for fast acquisition of structural information. Thus, after rapid imaging of larger specimens, navigation within the sample is possible. Subsequently, distinct features can be selected for further investigation using MPM. Additionally, by probing a different contrast, complementary information is obtained, and different biomarkers can be investigated. OCM images of tissue and cell samples are obtained, and distinctive features are evaluated using MPM to illustrate the benefits of the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20coherence%20microscopy" title="optical coherence microscopy">optical coherence microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphoton%20microscopy" title=" multiphoton microscopy"> multiphoton microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodal%20imaging" title=" multimodal imaging"> multimodal imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=two-photon%20fluorescence%20emission" title=" two-photon fluorescence emission"> two-photon fluorescence emission</a> </p> <a href="https://publications.waset.org/abstracts/102337/combined-optical-coherence-microscopy-and-spectrally-resolved-multiphoton-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102337.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">511</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">26462</span> Scanning Electronic Microscopy for Analysis of the Effects of Surfactants on De-Wrinkling and Dispersion of Graphene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kostandinos%20Katsamangas">Kostandinos Katsamangas</a>, <a href="https://publications.waset.org/abstracts/search?q=Fawad%20Inam"> Fawad Inam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Graphene was dispersed using a tip sonicator and the effect of surfactants were analysed.

Especially for transmission electron microscopy (TEM), the problem is even more important due to the complexity of the sample preparation technique and the many variables that can affect the conservation of structures, proper operation of the equipment used and then the quality of the images obtained. Animal tissues being transparent it is necessary to apply a contrast agent in order to identify the elements of their ultrastructural morphology. Several methods of contrastation of tissues for TEM imaging have already been developed. The most used are the “in block” contrastation and “in situ” contrastation. This report presents an alternative technique of application of contrast agent in vivo, i.e. before sampling. By this new method the electromicrographies of the tissue sections have better contrast compared to that in situ and present no artefact of precipitation of contrast agent. Another advantage is that a small amount of contrast is needed to get a good result given that most of them are expensive and extremely toxic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20quality" title="image quality">image quality</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopy%20research" title=" microscopy research"> microscopy research</a>, <a href="https://publications.waset.org/abstracts/search?q=staining%20technique" title=" staining technique"> staining technique</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra%20thin%20section" title=" ultra thin section"> ultra thin section</a> </p> <a href="https://publications.waset.org/abstracts/26993/new-method-to-increase-contrast-of-electromicrograph-of-rat-tissues-sections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26993.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">432</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">26460</span> Morphology Analysis of Apple-Carrot Juice Treated by Manothermosonication (MTS) and High Temperature Short Time (HTST) Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozan%20Kahraman">Ozan Kahraman</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao%20Feng"> Hao Feng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Manothermosonication (MTS), which consists of the simultaneous application of heat and ultrasound under moderate pressure (100-700 kPa), is one of the technologies which destroy microorganisms and inactivates enzymes. Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen as it passes through it. The environmental scanning electron microscope or ESEM is a scanning electron microscope (SEM) that allows for the option of collecting electron micrographs of specimens that are "wet," uncoated. These microscopy techniques allow us to observe the processing effects on the samples. This study was conducted to investigate the effects of MTS and HTST treatments on the morphology of apple-carrot juices by using TEM and ESEM microscopy. Apple-carrot juices treated with HTST (72 0C, 15 s), MTS 50 °C (60 s, 200 kPa), and MTS 60 °C (30 s, 200 kPa) were observed in both ESEM and TEM microscopy. For TEM analysis, a drop of the solution dispersed in fixative solution was put onto a Parafilm ® sheet. The copper coated side of the TEM sample holder grid was gently laid on top of the droplet and incubated for 15 min. A drop of a 7% uranyl acetate solution was added and held for 2 min. The grid was then removed from the droplet and allowed to dry at room temperature and presented into the TEM. For ESEM analysis, a critical point drying of the filters was performed using a critical point dryer (CPD) (Samdri PVT- 3D, Tousimis Research Corp., Rockville, MD, USA). After the CPD, each filter was mounted onto a stub and coated with gold/palladium with a sputter coater (Desk II TSC Denton Vacuum, Moorestown, NJ, USA). E.Coli O157:H7 cells on the filters were observed with an ESEM (Philips XL30 ESEM-FEG, FEI Co., Eindhoven, The Netherland). ESEM (Environmental Scanning Electron Microscopy) and TEM (Transmission Electron Microscopy) images showed extensive damage for the samples treated with MTS at 50 and 60 °C such as ruptured cells and breakage on cell membranes. The damage was increasing with increasing exposure time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MTS" title="MTS">MTS</a>, <a href="https://publications.waset.org/abstracts/search?q=HTST" title=" HTST"> HTST</a>, <a href="https://publications.waset.org/abstracts/search?q=ESEM" title=" ESEM"> ESEM</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a>, <a href="https://publications.waset.org/abstracts/search?q=E.COLI%20O157%3AH7" title=" E.COLI O157:H7"> E.COLI O157:H7</a> </p> <a href="https://publications.waset.org/abstracts/57139/morphology-analysis-of-apple-carrot-juice-treated-by-manothermosonication-mts-and-high-temperature-short-time-htst-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57139.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">285</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">26459</span> Scanning Electrochemical Microscopy Studies of Magnesium-Iron Galvanic Couple</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akram%20Alfantazi">Akram Alfantazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tirdad%20Nickchi"> Tirdad Nickchi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnesium galvanic corrosion plays an important role in the commercialization of Mg alloys in the automobile industry. This study aims at visualizing the electrochemical activity of the magnesium surface being coupled with pure iron in sulfate-chloride solutions. Scanning electrochemical microscopy was used to monitor the chemical activity of the surface and the data was compared with the conventional corrosion results such as potentiodynamic polarization, linear polarization, and immersion tests. The SECM results showed that the chemical reactivity of Mg is higher than phosphate-permanganate-coated Mg. Regions in the vicinity of the galvanic couple boundary are very active in the magnesium phase and fully protected in the iron phase. Scanning electrochemical microscopy results showed that the conversion coating provided good corrosion resistance for magnesium in the short-term but fails at long-term testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=galvanic%20corrosion" title=" galvanic corrosion"> galvanic corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium" title=" magnesium"> magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electrochemical%20microscopy" title=" scanning electrochemical microscopy"> scanning electrochemical microscopy</a> </p> <a href="https://publications.waset.org/abstracts/92833/scanning-electrochemical-microscopy-studies-of-magnesium-iron-galvanic-couple" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92833.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">288</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">26458</span> Effect of Retained Austenite Stability in Corrosion Mechanism of Dual Phase High Carbon Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Handoko">W.

Retained austenite is a meta-stable phase at room temperature, and stability of this phase governs the response of DHCS at different conditions. This research paper studies the effect of RA stability on corrosion behaviour of high carbon steels after they have been immersed into 1.0 M NaCl solution for various times. For this purpose, two different steels with different RA stabilities have been investigated. The surface morphology of the samples before and after corrosion attack was observed by secondary electron microscopy (SEM) and atomic force microscopy (AFM), along with the weight loss and Vickers hardness analysis. Microstructural investigations proved the preferential attack to retained austenite phase during corrosion. Hence, increase in the stability of retained austenite in dual-phase steels led to decreasing the weight loss rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20carbon%20steel" title="high carbon steel">high carbon steel</a>, <a href="https://publications.waset.org/abstracts/search?q=austenite%20stability" title=" austenite stability"> austenite stability</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title=" atomic force microscopy"> atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a> </p> <a href="https://publications.waset.org/abstracts/75437/effect-of-retained-austenite-stability-in-corrosion-mechanism-of-dual-phase-high-carbon-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75437.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">210</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">26457</span> Failure Analysis of a 304 Stainless Steel Flange Crack at Pipeline Transportation of Ethylene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Hasanpour">Parisa Hasanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Borooghani"> Bahram Borooghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Asadi"> Vahid Asadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current research, a catastrophic failure of a 304 stainless steel flange at pipeline transportation of ethylene in a petrochemical refinery was studied.

In case of conventional coatings, Al-Cr and Ti-Al metallic powders were deposited using plasma spray process followed by gas nitriding of the surface which was done in the lab with optimized parameters after conducting several trials on plasma-sprayed coated specimens. The physical vapor deposition process (PAPVD) was employed for depositing nanostructured TiAlN and AlCrN coatings. The field emission scanning electron microscopy (FE-SEM) with energy dispersive X-ray analysis (EDAX) attachment, X-ray diffraction (XRD) analysis, atomic force microscopy (AFM) analysis and the X-Ray mapping analysis techniques have been used to study surface and cross-sectional morphology of the coatings. The surface roughness and micro-hardness were also measured. A good adhesion of the conventional thick TiAlN and AlCrN coatings was found. The coatings under study are recommended for the applications to super-heater and re-heater tubes of the boilers based upon the outcomes of the research work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanostructure" title="nanostructure">nanostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20vapour%20deposition" title=" physical vapour deposition"> physical vapour deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=oxides" title=" oxides"> oxides</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20microscopy" title=" electron microscopy"> electron microscopy</a> </p> <a href="https://publications.waset.org/abstracts/112764/characterization-of-nanostructured-and-conventional-tialn-and-alcrn-coated-astm-sa213-t-11-boiler-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112764.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">140</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">26452</span> Influence of Argon Gas Concentration in N2-Ar Plasma for the Nitridation of Si in Abnormal Glow Discharge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Abbas">K.

Estupinan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Banana pseudostem fiber (BPF) and pineapple leaf fiber (PLF) for their excellent mechanical properties and biodegradability characteristics arouse interest in different areas of research. F In tropical regions, where the banana pseudostem and the pineapple leaf are transformed into hard-to-handle solid waste, they can be low-cost raw material and environmentally sustainable in research for composite materials. In terms of functionality of this type of fiber, an open structure would allow the adsorption and retention of organic, inorganic and metallic species. In general, natural fibers have closed structures on their surface with intricate internal arrangements that can be used for the solution of environmental problems and other technological uses, however it is not possible to access their internal structure and sublayers, exposing the fibers in the natural state. An alternative method to chemical and enzymatic treatment are the processes with the plasma treatments, which are known to be clean, economical and controlled. In this type of treatment, a gas contained in a reactor in the form of plasma acts on the fiber generating changes in its structure, morphology and topography. This work compares the effects on fibers of PLF and BPF treated with cold argon plasma, alternating time and current. These fibers are grown in the regions of Antioquia-Colombia. The morphological, compositional and wettability properties of the fibers were analyzed by Raman microscopy, contact angle measurements, scanning electron microscopy (SEM) and atomic force microscopy analysis (AFM). The treatment with cold plasma on PLF and BPF allowed increasing its wettability, the topography and the microstructural relationship between lignin and cellulose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20plasma" title="cold plasma">cold plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20angle" title=" contact angle"> contact angle</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20fibers" title=" natural fibers"> natural fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman" title=" Raman"> Raman</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=wettability" title=" wettability"> wettability</a> </p> <a href="https://publications.waset.org/abstracts/96909/wettability-properties-of-pineapple-leaf-fibers-and-banana-pseudostem-fibers-treated-by-cold-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96909.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">156</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">26450</span> Atomic Force Microscopy Studies of DNA Binding Properties of the Archaeal Mini Chromosome Maintenance Complex</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amna%20Abdalla%20Mohammed%20Khalid">Amna Abdalla Mohammed Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Pietro%20Parisse"> Pietro Parisse</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Onesti"> Silvia Onesti</a>, <a href="https://publications.waset.org/abstracts/search?q=Loredana%20Casalis"> Loredana Casalis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Basic cellular processes as DNA replication are crucial to cell life.

It was shown that sodium chloride, due to its higher hardness, maintain its morphology during cold compaction, and cause better replication in porous scaffolds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Spacer" title="Spacer">Spacer</a>, <a href="https://publications.waset.org/abstracts/search?q=Titanium%20Scaffold" title=" Titanium Scaffold"> Titanium Scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=Pore%20Morphology" title=" Pore Morphology"> Pore Morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=Space%20Holder%20Technique" title=" Space Holder Technique"> Space Holder Technique</a> </p> <a href="https://publications.waset.org/abstracts/66028/effect-of-the-hardness-of-spacer-agent-on-structural-properties-of-metallic-scaffolds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66028.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">289</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">26448</span> Hybrid Bimodal Magnetic Force Microscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fern%C3%A1ndez-Brito%20David">Fernández-Brito David</a>, <a href="https://publications.waset.org/abstracts/search?q=Lopez-Medina%20Javier%20Alonso"> Lopez-Medina Javier Alonso</a>, <a href="https://publications.waset.org/abstracts/search?q=Murillo-Bracamontes%20Eduardo%20Antonio"> Murillo-Bracamontes Eduardo Antonio</a>, <a href="https://publications.waset.org/abstracts/search?q=Palomino-Ovando%20Martha%20Alicia"> Palomino-Ovando Martha Alicia</a>, <a href="https://publications.waset.org/abstracts/search?q=Gervacio-Arciniega%20Jos%C3%A9%20Juan"> Gervacio-Arciniega José Juan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnetic Force Microscopy (MFM) is an Atomic Force Microscopy (AFM) technique that characterizes, at a nanometric scale, the magnetic properties of ferromagnetic materials. Conventional MFM works by scanning in two different AFM modes. The first one is tapping mode, in which the cantilever has short-range force interactions with the sample, with the purpose to obtain the topography. Then, the lift AFM mode starts, raising the cantilever to maintain a fixed distance between the tip and the surface of the sample, only interacting with the magnetic field forces of the sample, which are long-ranged. In recent years, there have been attempts to improve the MFM technique. Bimodal MFM was first theoretically developed and later experimentally proven. In bimodal MFM, the AFM internal piezoelectric is used to cause the cantilever oscillations in two resonance modes simultaneously, the first mode detects the topography, while the second is more sensitive to the magnetic forces between the tip and the sample. However, it has been proven that the cantilever vibrations induced by the internal AFM piezoelectric ceramic are not optimal, affecting the bimodal MFM characterizations. Moreover, the Secondary Resonance Magnetic Force Microscopy (SR-MFM) was developed. In this technique, a coil located below the sample generates an external magnetic field. This alternating magnetic field excites the cantilever at a second frequency to apply the Bimodal MFM mode. Nonetheless, for ferromagnetic materials with a low coercive field, the external field used in SR-MFM technique can modify the magnetic domains of the sample. In this work, a Hybrid Bimodal MFM (HB-MFM) technique is proposed. In HB-MFM, the bimodal MFM is used, but the first resonance frequency of the cantilever is induced by the magnetic field of the ferromagnetic sample due to its vibrations caused by a piezoelectric element placed under the sample. The advantages of this new technique are demonstrated through the preliminary results obtained by HB-MFM on a hard disk sample. Additionally, traditional two pass MFM and HB-MFM measurements were compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20force%20microscopy" title="magnetic force microscopy">magnetic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title=" atomic force microscopy"> atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetism" title=" magnetism"> magnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=bimodal%20MFM" title=" bimodal MFM"> bimodal MFM</a> </p> <a href="https://publications.waset.org/abstracts/172742/hybrid-bimodal-magnetic-force-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172742.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">72</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">26447</span> Single-Molecule Analysis of Structure and Dynamics in Polymer Materials by Super-Resolution Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroyuki%20Aoki">Hiroyuki Aoki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The physical properties of polymer materials are dependent on the conformation and molecular motion of a polymer chain. Therefore, the structure and dynamic behavior of the single polymer chain have been the most important concerns in the field of polymer physics. However, it has been impossible to directly observe the conformation of the single polymer chain in a bulk medium. In the current work, the novel techniques to study the conformation and dynamics of a single polymer chain are proposed. Since a fluorescence method is extremely sensitive, the fluorescence microscopy enables the direct detection of a single molecule. However, the structure of the polymer chain as large as 100 nm cannot be resolved by conventional fluorescence methods because of the diffraction limit of light. In order to observe the single chains, we developed the labeling method of polymer materials with a photo-switchable dye and the super-resolution microscopy. The real-space conformational analysis of single polymer chains with the spatial resolution of 15-20 nm was achieved. The super-resolution microscopy enables us to obtain the three-dimensional coordinates; therefore, we succeeded the conformational analysis in three dimensions. The direct observation by the nanometric optical microscopy would reveal the detailed information on the molecular processes in the various polymer systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20materials" title="polymer materials">polymer materials</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20molecule" title=" single molecule"> single molecule</a>, <a href="https://publications.waset.org/abstracts/search?q=super-resolution%20techniques" title=" super-resolution techniques"> super-resolution techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=conformation" title=" conformation"> conformation</a> </p> <a href="https://publications.waset.org/abstracts/57901/single-molecule-analysis-of-structure-and-dynamics-in-polymer-materials-by-super-resolution-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57901.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">306</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">26446</span> Self-Assembly of Monodisperse Oleic Acid-Capped Superparamagnetic Iron Oxide Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huseyin%20Kavas">Huseyin Kavas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oleic acid (OA) capped superparamagnetic iron oxide nanoparticles (SPION) were synthesized by a thermal decomposition method.

The effect of the microwave and pH on the crystallite size, morphology, structure, energy band gap and surface area of NiO have been investigated by means of powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet visible spectroscopy (UV-vis) and BET surface area studies. X-ray diffraction studies showed the formation of monophasic and highly crystalline cubic NiO. TEM analysis led to decrease the average grain size of NiO nanoparticles from 16.5 nm to 14 nm on increasing the amount of NaOH. FTIR studies also confirm the formation of NiO nanoparticles. It was observed that on increasing the volume of NaOH, the optical band gap energy (2.85 eV to 2.95 eV) and specific surface area (33.1 to 39.8 m2/g) increases, however the average particles size decreases (16.5 nm to 14 nm). This method may be extended to large scale synthesis of other metal oxides nanoparticles and the present study could be used for the potential applications in water treatment and many other fields. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BET%20surface%20area%20analysis" title="BET surface area analysis">BET surface area analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20microscopy" title=" electron microscopy"> electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20properties" title=" optical properties"> optical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20techniques" title=" X-ray techniques "> X-ray techniques </a> </p> <a href="https://publications.waset.org/abstracts/10258/microwave-synthesis-optical-properties-and-surface-area-studies-of-nio-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10258.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">396</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">26444</span> Physical, Morphological, and Rheological Properties of Polypropylene Modified Bitumen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nioushasadat%20Haji%20Seyed%20Javadi">Nioushasadat Haji Seyed Javadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ailar%20Hajimohammadi"> Ailar Hajimohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser%20Khalili"> Nasser Khalili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The common method to improve the performance of asphalt binders is through modification. The utilization of recycled plastics for asphalt modification has been the subject of research studies due to their environmental and economic benefits over using commercial polymers. Polypropylene (PP) is one of the most available recycled plastics in Australia. Unlike other plastics, its contamination with other plastics during the recycling process is negligible. Therefore, the quality of recycled plastic is high, which makes it a good candidate for road construction applications. To assess its effectiveness for bitumen modification, three different grades of PP were selected. The PP grades were compared for blendability with bitumen, and the best suitable grade was chosen for further studies. The PP-modified bitumen and the base bitumen were then compared through physical and rheological properties. The stability of the PP-modified bitumen at elevated temperatures was measured, and the morphology of the samples before and after the storage stability was characterized by fluorescent microscopy. The results showed that PP had a significant influence on reducing the penetration and increasing the viscosity and the rutting resistance of the virgin bitumen. Storage stability test results indicated that the difference between the softening point of the top and bottom section of the tube sample is below the defined limit, which means the PP-modified bitumen is storage stable. However, the fluorescence microscopy results showed that the distribution of the PP particles in the bitumen matrix in the top and bottom sections of the tube are significantly different, which is an indicator of poor storage stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title="polypropylene">polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20plastic" title=" waste plastic"> waste plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=bitumen" title=" bitumen"> bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20pavements" title=" road pavements"> road pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20stability" title=" storage stability"> storage stability</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescent%20microscopy" title=" fluorescent microscopy"> fluorescent microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a> </p> <a href="https://publications.waset.org/abstracts/152080/physical-morphological-and-rheological-properties-of-polypropylene-modified-bitumen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152080.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">78</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">26443</span> Rapid Biosynthesis of Silver-Montmorillonite Nanocomposite Using Water Extract of Satureja hortensis L. and Evaluation of the Antibacterial Capacities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Sedaghat">Sajjad Sedaghat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, facile and green biosynthesis and characterization of silver–montmorillonite (MMT) nanocomposite is reported at room temperature.

This and other successful applications underlie the growing attention that both basic and applied research are devoting to these systems, and to their unique rheological and flow properties. One of the key research topics is the occurrence of flow instabilities at high shear rates (such as shear banding), with the possibility of appearance of flow induced structures. In this scenario, microfluidics is a powerful tool to get a deeper insight into the flow behavior of a wormlike micellar solution, as the high confinement of a microfluidic device facilitates the onset of the flow instabilities; furthermore, thanks to its small dimensions, it can be coupled with optical microscopy, allowing a direct visualization of flow structuring phenomena. Here, the flow of a widely used wormlike micellar solution through a glass capillary has been studied, by coupling the microfluidic device with μPIV techniques. The direct visualization of flow-induced structures and the flow visualization analysis highlight a relationship between solution structuring and the onset of discontinuities in the velocity profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20instabilities" title="flow instabilities">flow instabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=flow-induced%20structures" title=" flow-induced structures"> flow-induced structures</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%BCPIV" title=" μPIV"> μPIV</a>, <a href="https://publications.waset.org/abstracts/search?q=wormlike%20micelles" title=" wormlike micelles "> wormlike micelles </a> </p> <a href="https://publications.waset.org/abstracts/68641/direct-visualization-of-shear-induced-structures-in-wormlike-micellar-solutions-by-microfluidics-and-advanced-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68641.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">346</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">26441</span> Development of a New Characterization Method to Analyse Cypermethrin Penetration in Wood Material by Immunolabelling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Tapin-Lingua">Sandra Tapin-Lingua</a>, <a href="https://publications.waset.org/abstracts/search?q=Katia%20Ruel"> Katia Ruel</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Paul%20Joseleau"> Jean-Paul Joseleau</a>, <a href="https://publications.waset.org/abstracts/search?q=Daouia%20Messaoudi"> Daouia Messaoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Fahy"> Olivier Fahy</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Petit-Conil"> Michel Petit-Conil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The preservative efficacy of organic biocides is strongly related to their capacity of penetration and retention within wood tissues. The specific detection of the pyrethroid insecticide is currently obtained after extraction followed by chemical analysis by chromatography techniques. However visualizing the insecticide molecule within the wood structure requires specific probes together with microscopy techniques. Therefore, the aim of the present work was to apply a new methodology based on antibody-antigen recognition and electronic microscopy to visualize directly pyrethroids in the wood material. A polyclonal antibody directed against cypermethrin was developed and implement it on Pinus sylvestris wood samples coated with technical cypermethrin. The antibody was tested on impregnated wood and the specific recognition of the insecticide was visualized in transmission electron microscopy (TEM). The immunogold-TEM assay evidenced the capacity of the synthetic biocide to penetrate in the wood. The depth of penetration was measured on sections taken at increasing distances from the coated surface of the wood. Such results correlated with chemical analyzes carried out by GC-ECD after extraction. In addition, the immuno-TEM investigation allowed visualizing, for the first time at the ultrastructure scale of resolution, that cypermethrin was able to diffuse within the secondary wood cell walls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cypermethrin" title="cypermethrin">cypermethrin</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticide" title=" insecticide"> insecticide</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20penetration" title=" wood penetration"> wood penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20retention" title=" wood retention"> wood retention</a>, <a href="https://publications.waset.org/abstracts/search?q=immuno-transmission%20electron%20microscopy" title=" immuno-transmission electron microscopy"> immuno-transmission electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=polyclonal%20antibody" title=" polyclonal antibody"> polyclonal antibody</a> </p> <a href="https://publications.waset.org/abstracts/36690/development-of-a-new-characterization-method-to-analyse-cypermethrin-penetration-in-wood-material-by-immunolabelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36690.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">413</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">26440</span> Elaboration and Characterization of Silver Nanoparticles for Therapeutic and Environmental Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Bouloudenine">Manel Bouloudenine</a>, <a href="https://publications.waset.org/abstracts/search?q=Karima%20Djeddou"> Karima Djeddou</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadjer%20Ben%20Manser"> Hadjer Ben Manser</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Soualah%20Alila"> Hana Soualah Alila</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohmed%20Bououdina"> Mohmed Bououdina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This survey research involves the elaboration and characterization of silver nanoparticles for therapeutic and environmental applications. The silver nanoparticles "Ag NPs" were synthesized by reducing AgNO3 with microwaves. The characterization of nanoparticles was done by using Transmission Electron Microscopy " TEM ", Energy Dispersive Spectroscopy "EDS", Selected Area Electron Diffraction "SEAD", UV-Visible Spectroscopy and Dynamic Light Scattering "DLS". Transmission Electron Microscopy and Electron Diffraction have confirmed the nanoscale, the shape, and the crystalline quality of as synthesized silver nanoparticles. Elementary analysis has proved the purity of Ag NPs and the presence of the Surface Plasmon Resonance phenomenon "SPR". A strong absorption shift was observed in the visible range of the UV-visible spectrum of as synthesized Ag NPs, which indicates the presence of metallic silver. When the strong absorption in the ultraviolet range of the spectrum has revealed the presence of ionic Ag NPs ionic Ag aggregates species. The autocorrelation function measured by the Dynamic Light Scattering has shown a strong monodispersed character of Ag NPs, which is indicated by the presence of a single size population, with a minima and a maxima laying between 40 and 111 nm. Related to other research, our results confirm the performance properties of as synthesized Ag NPs, which allows them to be performing in many technological applications, including therapeutic and environmental ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silvers%20nanoparticles" title="silvers nanoparticles">silvers nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=microwaves" title=" microwaves"> microwaves</a>, <a href="https://publications.waset.org/abstracts/search?q=EDS" title=" EDS"> EDS</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a> </p> <a href="https://publications.waset.org/abstracts/146054/elaboration-and-characterization-of-silver-nanoparticles-for-therapeutic-and-environmental-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146054.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">147</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">26439</span> A Comprehensive Analysis of the Rheological Properties of Polymer Hydrogels in Order to Explore Their Potential for Practical Utilization in Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raana%20Babadi%20Fathipour">Raana Babadi Fathipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogels are three-dimensional structures formed by the interweaving of polymeric materials, possessing the remarkable ability to imbibe copious amounts of water. Numerous methodologies have been devised for examining and understanding the properties of these synthesized gels. Amongst them, spectroscopic techniques such as ultraviolet/visible (UV/Vis) and Fourier-transform infrared (FTIR) spectroscopy offer a glimpse into molecular and atomic aspects. Additionally, diffraction methods like X-ray diffraction (XRD) enable one to measure crystallinity within the gel's structure, while microscopy tools encompassing scanning electron microscopy (SEM) and transmission electron microscopy (TEM) provide insights into surface texture and morphology. Furthermore, rheology serves as an invaluable tool for unraveling the viscoelastic behavior inherent in hydrogels—a parameter crucial not only to numerous industries, including pharmaceuticals, cosmetics, food processing, agriculture and water treatment, but also pivotal to related fields of research. Likewise, the ultimate configuration of the product is contingent upon its characterization at a microscopic scale in order to comprehend the intricacies of the hydrogel network's structure and interaction dynamics in response to external forces. Within this present scrutiny, our attention has been devoted to unraveling the intricate rheological tendencies exhibited by materials founded on synthetic, natural, and semi-synthetic hydrogels. We also explore their practical utilization within various facets of everyday life from an industrial perspective. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheology" title="rheology">rheology</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogels%20characterization" title=" hydrogels characterization"> hydrogels characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelastic%20behavior" title=" viscoelastic behavior"> viscoelastic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=application" title=" application"> application</a> </p> <a href="https://publications.waset.org/abstracts/171982/a-comprehensive-analysis-of-the-rheological-properties-of-polymer-hydrogels-in-order-to-explore-their-potential-for-practical-utilization-in-industries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171982.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">50</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">26438</span> Annealing of the Contact between Graphene and Metal: Electrical and Raman Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Sakavi%C4%8Dius">A.

The developed, highly transparent coatings are produced by a chemical route (sol-gel method) using two silica-based precursors, hexamethyldisilazane and tetraethoxysilane (HMDS/TEOS). The addition of zinc oxide nanoparticles (ZnO NPs) within the gel provides a photocatalytic property to the final coating. The prepared gels were deposited on glass slides using different methods. The properties of the coatings were characterized by optical microscopy, scanning electron microscopy, UV-VIS-NIR spectrophotometer, and water contact angle method. The results show that the obtained coatings are homogeneous and have a hydrophobic character. In particular, after thermal treatment, the HMDS/TEOS@ZnO charged gel deposited on glass constitutes a coating capable of degrading methylene blue (MB) under UV irradiation. Optical transmission reaches more than 90% in most of the visible light spectrum. Synthetized coatings have also demonstrated their mechanical durability and self-cleaning ability. <p class="card-text"><strong>Keywords:</strong> <a
