They are considered as an important category of new materials having innovative characteristics by combining the specific intrinsic properties of inorganic compounds (semiconductors) with the grafted organic species. This open the way to improved properties and spectacular applications in various and important fields, especially in the environment. In this work, nano materials based-semiconductors were elaborated by chemical route. The obtained surfaces were grafted with organic functional groups. The functionalization process was optimized in order to confer to the hybrid nano material a good stability as well as the right properties required for the subsequent applications. Different characterization techniques were used to investigate the resulting nano structures, such as SEM, UV-Visible, FTIR, Contact angle and electro chemical measurements. Finally, applications were envisaged in environmental area. The elaborated nano structures were tested for the detection and the elimination of pollutants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20materials" title="hybrid materials">hybrid materials</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20silicon" title=" porous silicon"> porous silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=peptide" title=" peptide"> peptide</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20detection" title=" metal detection"> metal detection</a> </p> <a href="https://publications.waset.org/abstracts/10685/functional-nanomaterials-for-environmental-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10685.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">499</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">171</span> Effect of Two Entomopathogenic Fungi Beauveria bassiana and Metarhizium anisopliae var. acridum on the Haemolymph of the Desert Locust Schistocerca gregaria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Bissaad">Fatima Zohra Bissaad</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Bounaceur"> Farid Bounaceur</a>, <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Behidj"> Nassima Behidj</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadjiba%20Chebouti"> Nadjiba Chebouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Halouane"> Fatma Halouane</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahia%20Doumandji-Mitiche"> Bahia Doumandji-Mitiche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of <em>Beauveria bassiana</em> and <em>Metarhizium anisopliae</em> var. <em>acridum</em> on the 5<sup>th </sup>instar nymphs of <em>Schistocerca gregaria</em> was studied in the laboratory.

The chemiresistive module was prepared, characterized, and evaluated for performance. Structural and morphological characterizations of the composite were carried out using FTIR, Raman spectroscopy, and XRD analyses. After exposure to NO and NO₂ gases in both static and dynamic modes, the sensitivity, selectivity, limit of detection, and response time of the sensor were determined at ambient temperature. The resulting sensor showed high sensitivity, selectivity, and reversibility, with a low limit of detection of 1 ppm. A composite of polypyrrole and graphene functionalized with aryl 4-carboxy benzene diazonium salt was synthesized and characterized using FTIR, scanning electron microscopy, transmission electron microscopy, UV-visible, and X-ray diffraction. The PPy-rGOArCOOH composite exhibited a good electrical resistance response to NO₂ at room temperature and showed enhanced NO₂-sensing properties compared to PPy-rGO thin films. The selectivity and stability of the NO₂ sensor based on the PPy/rGO-ArCOOH nanocomposite were also investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conducting%20polymers" title="conducting polymers">conducting polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20treated%20graphene" title=" surface treated graphene"> surface treated graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=diazonium%20salt" title=" diazonium salt"> diazonium salt</a>, <a href="https://publications.waset.org/abstracts/search?q=polypyrrole" title=" polypyrrole"> polypyrrole</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitrogen%20oxide%20sensing" title=" Nitrogen oxide sensing"> Nitrogen oxide sensing</a> </p> <a href="https://publications.waset.org/abstracts/164940/development-of-a-semiconductor-material-based-on-functionalized-graphene-application-to-the-detection-of-nitrogen-oxides-no" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164940.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">168</span> Forensic Entomology in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Taleb">Meriem Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Tail"> Ghania Tail</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zohra%20Kara"> Fatma Zohra Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Djedouani"> Brahim Djedouani</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Moussa"> T. Moussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forensic entomology is the use of insects and their arthropod relatives as silent witnesses to aid legal investigations by interpreting information concerning a death. The main purpose of forensic entomology is to establish the postmortem interval or PMI Postmortem interval is a matter of crucial importance in the investigations of homicide and other untimely deaths when the body found is after three days. Forensic entomology has grown immensely as a discipline in the past thirty years. In Algeria, forensic entomology was introduced in 2010 by the National Institute for Criminalistics and Criminology of the National Gendarmerie (NICC). However, all the work that has been done so far in this growing field in Algeria has been unknown at both the national and international levels. In this context, the aim of this paper is to describe the state of forensic entomology in Algeria. The Laboratory of Entomology of the NICC is the only one of its kind in Algeria. It started its activities in 2010, consisting of two specialists. The main missions of the laboratory are estimation of the PMI by the analysis of entomological evidence, and determination if the body was moved. Currently, the laboratory is performing different tasks such as the expert work required by investigators to estimate the PMI using the insects. The estimation is performed by the accumulated degree days method (ADD) in most of the cases except for those where the cadaver is in dry decay. To assure the quality of the entomological evidence, crime scene personnel are trained by the laboratory of Entomology of the NICC. Recently, undergraduate and graduate students have been studying carrion ecology and insect activity in different geographic locations of Algeria using rabbits and wild boar cadavers as animal models. The Laboratory of Entomology of the NICC has also been involved in some of these research projects. Entomotoxicology experiments are also conducted with the collaboration of the Toxicology Department of the NICC. By dint of hard work that has been performed by the Laboratory of Entomology of the NICC, official bodies have been adopting more and more the use of entomological evidence in criminal investigations in Algeria, which is commendable. It is important, therefore, that steps are taken to fill in the gaps in the knowledge necessary for entomological evidence to have a useful future in criminal investigations in Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=corpse" title=" corpse"> corpse</a>, <a href="https://publications.waset.org/abstracts/search?q=insects" title=" insects"> insects</a>, <a href="https://publications.waset.org/abstracts/search?q=postmortem%20interval" title=" postmortem interval"> postmortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=expertise" title=" expertise"> expertise</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34230/forensic-entomology-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34230.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">407</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">167</span> An Analysis of Methodological Approaches of Ahmed Cevdet and Fatma Aliye towards the Ottoman Historiography in a Comparative Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aysen%20Muderrisoglu%20Esiner">Aysen Muderrisoglu Esiner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As an intellectual, scholar, bureaucrat, and statesman, Ahmed Cevdet Pasha (1822-1895) was the prominent figure of “Tanzimat” (reorganization) reforms of the Ottoman State while his daughter Fatma Aliye (1862-1936) was a novelist, columnist, essayist, and women’s rights activist. His father had numerous books on law, grammar, linguistics, logic, and astronomy, moreover, Aliye accepted as the first female novelist in the Turkish literature and the Islamic world. Even if she was better known as a novelist, she also published some works on philosophy, Islam, poetry. In addition, Aliye who was one of the pioneers of the Ottoman women’s movement, also wrote historical works. Her historical works which titled as Tarih-i Osmaninin Bir Devre-i Mühimmesi Kosova Zaferi-Ankara Hezimeti (An Important Era of the Ottoman History: Kosova Victory-Ankara Defeat), and Ahmed Cevdet Paşa ve Zamanı (Ahmed Cevdet Pasha and His Time) have been generally ignored in the literature. However, Aliye’s works in history field are worth being studied in terms of her methodological approach to the Ottoman historiography. On the other hand, written by Ahmed Cevdet Pasha, such as Tarih-i Cevdet (History of Cevdet), Tezâkir (Memoir), Mâruzat (Reports, the events that took place between 1839-1876, 1890), Kısas-ı Enbiya ve Tevârîh-i Hulefa (Retaliation of the Prophets and the History of Calips), Kırım ve Kafkas Tarihçesi (Crimean and Caucasian History) are the most important works in terms of historiography in the 19th century. In contrast to the traditional methodology, Cevdet Pasha brought a new understanding to the Ottoman historiography by making a synthesis between the traditional and modern methods. In this research, the historical works of these two prominent figures of the Ottoman State will be analyzed in terms of their approaches to the Ottoman historiography while evaluating the following questions: to what extent that their use of local and foreign historical sources and their handling of the historical events differ, or if it is possible to talk about a methodological similarities in terms of historiography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Cevdet%20Pasha" title="Ahmed Cevdet Pasha">Ahmed Cevdet Pasha</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Aliye" title=" Fatma Aliye"> Fatma Aliye</a>, <a href="https://publications.waset.org/abstracts/search?q=historiography" title=" historiography"> historiography</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/129590/an-analysis-of-methodological-approaches-of-ahmed-cevdet-and-fatma-aliye-towards-the-ottoman-historiography-in-a-comparative-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129590.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">257</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">166</span> Application of Forensic Entomology to Estimate the Post Mortem Interval</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Taleb">Meriem Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghania%20Tail"> Ghania Tail</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Zohra%20Kara"> Fatma Zohra Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Djedouani"> Brahim Djedouani</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Moussa"> T.

The main purpose of forensic entomology is to establish the post mortem interval or PMI. Three days after the death, insect evidence is often the most accurate and sometimes the only method of determining elapsed time since death. This work presents the estimation of the PMI in an experiment to test the reliability of the accumulated degree days (ADD) method and the application of this method in a real case. The study was conducted at the Laboratory of Entomology at the National Institute for Criminalistics and Criminology of the National Gendarmerie, Algeria. The domestic rabbit Oryctolagus cuniculus L. was selected as the animal model. On 08th July 2012, the animal was killed. Larvae were collected and raised to adulthood. Estimation of oviposition time was calculated by summing up average daily temperatures minus minimum development temperature (also specific to each species). When the sum is reached, it corresponds to the oviposition day. Weather data were obtained from the nearest meteorological station. After rearing was accomplished, three species emerged: Lucilia sericata, Chrysomya albiceps, and Sarcophaga africa. For Chrysomya albiceps species, a cumulation of 186°C is necessary. The emergence of adults occured on 22nd July 2012. A value of 193.4°C is reached on 9th August 2012. Lucilia sericata species require a cumulation of 207°C. The emergence of adults occurred on 23rd, July 2012. A value of 211.35°C is reached on 9th August 2012. We should also consider that oviposition may occur more than 12 hours after death. Thus, the obtained PMI is in agreement with the actual time of death. We illustrate the use of this method during the investigation of a case of a decaying human body found on 03rd March 2015 in Bechar, South West of Algerian desert. Maggots were collected and sent to the Laboratory of Entomology. Lucilia sericata adults were identified on 24th March 2015 after emergence. A sum of 211.6°C was reached on 1st March 2015 which corresponds to the estimated day of oviposition. Therefore, the estimated date of death is 1st March 2015 ± 24 hours. The estimated PMI by accumulated degree days (ADD) method seems to be very precise. Entomological evidence should always be used in homicide investigations when the time of death cannot be determined by other methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=accumulated%20degree%20days" title=" accumulated degree days"> accumulated degree days</a>, <a href="https://publications.waset.org/abstracts/search?q=postmortem%20interval" title=" postmortem interval"> postmortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=diptera" title=" diptera"> diptera</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34231/application-of-forensic-entomology-to-estimate-the-post-mortem-interval" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34231.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">294</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">165</span> Characterization of the in 0.53 Ga 0.47 as n+nn+ Photodetectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zohra%20Mahi">Fatima Zohra Mahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Varani"> Luca Varani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present an analytical model for the calculation of the sensitivity, the spectral current noise and the detectivity for an optically illuminated In0.53Ga0.47As n+nn+ diode.

The extraction is done by steam distillation of water which brought us a very significant return of 4.65%. The analysis of the essential oil is performed by GC/MS and has allowed us to identify 32 compounds in the oil of D. carota flowering tops of Bouira.

Meshless methods offer special properties to get rid of well-known drawbacks of the FEM. The main objective of Meshless Methods is to eliminate the difficulty of meshing and remeshing the entire structure by simply insertion or deletion of nodes, and alleviate other problems associated with the FEM, such as element distortion, locking and others. In this study, a robust numerical implementation of an Element Free Galerkin Method for an elastoplastic coupled to damage problem is presented. Several results issued from the numerical simulations by a DynamicExplicit resolution scheme are analyzed and critically compared with Element Finite Method results. Finally, different numerical examples are carried out to demonstrate the efficiency of this method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20explicit" title=" dynamic explicit"> dynamic explicit</a>, <a href="https://publications.waset.org/abstracts/search?q=elastoplasticity" title=" elastoplasticity"> elastoplasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=isotropic%20hardening" title=" isotropic hardening"> isotropic hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=meshless" title=" meshless"> meshless</a> </p> <a href="https://publications.waset.org/abstracts/46273/an-implementation-of-meshless-method-for-modeling-an-elastoplasticity-coupled-to-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46273.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">295</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">147</span> Development of MEMS Based 3-Axis Accelerometer for Hand Movement Monitoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Aziz%20Ali%20Manjiyani">Zohra Aziz Ali Manjiyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Renju%20Thomas%20Jacob"> Renju Thomas Jacob</a>, <a href="https://publications.waset.org/abstracts/search?q=Keerthan%20Kumar"> Keerthan Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This project develops a hand movement monitoring system, which feeds the data into the computer and gives the 3D image rotation according to the direction of the tilt and hence monitoring the movement of the hand in context to its tilt.

Maghnite-H+ is a solid catalyst non-toxic. The presence of PEG chains leads to a break in the growth of PCL chains and consequently leads to the copolymer tri-block PCL-PEG-PCL. The objective of this study was to synthesize and characterize of Solid Polymeric Materials. The highly hydrophilic nature of polyethylene glycol has sparked our interest in developing a Solid Polymeric based e-caprolactone and poly (ethylene glycol). PCL and PEG are biocompatible materials. Their ring-opening copolymerization using Maghnite H+ makes to the Solid Polymeric Materials. The morphology and structure of Solid polymeric Materials were characterized by ¹H and ¹³C-NMR spectra and Gel Permeation Chromatography (GPC). This paper developed the application of Maghnite-H+ as an efficient catalyst by an easy-to-handle procedure to get solid polymeric materials. A cationic mechanism for the copolymerization reaction was proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=block%20copolymers" title="block copolymers">block copolymers</a>, <a href="https://publications.waset.org/abstracts/search?q=maghnite" title=" maghnite"> maghnite</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28e-caprolactone%29" title=" poly(e-caprolactone)"> poly(e-caprolactone)</a> </p> <a href="https://publications.waset.org/abstracts/97417/synthesis-of-solid-polymeric-materials-by-maghnite-h-as-a-green-catalyst" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97417.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">167</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">145</span> A Secure Digital Signature Scheme with Fault Tolerance Based on the Improved RSA System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20El-Kamchouchi">H.

In this paper, we propose a secure and efficient digital signature scheme with fault tolerance based on the improved RSA system. The proposed scheme for the RSA cryptosystem contains three prime numbers and overcome several attacks possible on RSA. By using the Chinese Reminder Theorem (CRT) the proposed scheme has a speed improvement on the RSA decryption side and it provides high security also. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20signature" title="digital signature">digital signature</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20tolerance" title=" fault tolerance"> fault tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=RSA" title=" RSA"> RSA</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20analysis" title=" security analysis"> security analysis</a> </p> <a href="https://publications.waset.org/abstracts/51269/a-secure-digital-signature-scheme-with-fault-tolerance-based-on-the-improved-rsa-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51269.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">476</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">144</span> Analysis of the Volatile Organic Compounds of Tillandsia Flowers by HS-SPME/GC-MS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Gonzalez">Alexandre Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Benfodda"> Zohra Benfodda</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20B%C3%A9nim%C3%A9lis"> David Bénimélis</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Xavier%20Fontaine"> Jean-Xavier Fontaine</a>, <a href="https://publications.waset.org/abstracts/search?q=Roland%20Molini%C3%A9"> Roland Molinié</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Meffre"> Patrick Meffre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Volatile organic compounds (VOCs) emitted by flowers play an important role in plant ecology. However, the Tillandsia genus has been scarcely studied according to the VOCs emitted by flowers. Tillandsia are epiphytic flowering plants belonging to the Bromeliaceae family. The VOCs composition of twelve unscented and two faint-scented Tillandsia species was studied. The headspace solid phase microextraction coupled with gas chromatography combined with mass spectrometry method was used to explore the chemical diversity of the VOCs. This study allowed the identification of 65 VOCs among the fourteen species, and between six to twenty-five compounds were identified in each of the species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tillandsia" title="tillandsia">tillandsia</a>, <a href="https://publications.waset.org/abstracts/search?q=headspace%20solid%20phase%20microextraction%20%28HS-SPME%29" title=" headspace solid phase microextraction (HS-SPME)"> headspace solid phase microextraction (HS-SPME)</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20chromatography-mass%20spectrometry%20%28GC-MS%29" title=" gas chromatography-mass spectrometry (GC-MS)"> gas chromatography-mass spectrometry (GC-MS)</a>, <a href="https://publications.waset.org/abstracts/search?q=scentless%20flowers" title=" scentless flowers"> scentless flowers</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20organic%20compounds%20%28VOCs%29" title=" volatile organic compounds (VOCs)"> volatile organic compounds (VOCs)</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA%20analysis" title=" PCA analysis"> PCA analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=heatmap" title=" heatmap"> heatmap</a> </p> <a href="https://publications.waset.org/abstracts/152016/analysis-of-the-volatile-organic-compounds-of-tillandsia-flowers-by-hs-spmegc-ms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152016.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">124</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">143</span> Factors Influencing University Student's Acceptance of New Technology </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Khadra">Fatma Khadra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this research is to identify the acceptance of new technology in a sample of 150 Participants from Qatar University. Based on the Technology Acceptance Model (TAM), we used the Davis’s scale (1989) which contains two item scales for Perceived Usefulness and Perceived Ease of Use. The TAM represents an important theoretical contribution toward understanding how users come to accept and use technology. This model suggests that when people are presented with a new technology, a number of variables influence their decision about how and when they will use it. The results showed that participants accept more technology because flexibility, clarity, enhancing the experience, enjoying, facility, and useful. Also, results showed that younger participants accept more technology than others. <p class="card-text"><strong>Keywords:</strong> <a
