This study describes the lexical classification of compounds in Berom and, specifically, examines the semantics of nominal compounds with N-V constituents. The study relied on a data set of 200 compounds that were drawn from Bere Naha (a newsletter publication in Berom). Contrary to the nominalization process in defining the lexical class of compounds in languages, the study revealed that verbal and adjectival classes of compounds are also attested in Berom and N-V nominal compounds have an agentive or locative interpretation that is not solely determined by the meaning of the constituents of the compound but by the context of the usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=berom" title="berom">berom</a>, <a href="https://publications.waset.org/abstracts/search?q=berom%20compounds" title=" berom compounds"> berom compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=nominal%20compound" title=" nominal compound"> nominal compound</a>, <a href="https://publications.waset.org/abstracts/search?q=N-V%20compounds" title=" N-V compounds"> N-V compounds</a> </p> <a href="https://publications.waset.org/abstracts/171026/lexical-classification-of-compounds-in-berom-a-semantic-description-of-n-v-nominal-compounds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171026.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">2356</span> Radio Labeling and Characterization of Cysteine and Its Derivatives with Tc99m and Their Bio-Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Ashfaq">Rabia Ashfaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Iqbal"> Saeed Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Atiq%20ur%20Rehman"> Atiq ur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Irfanullah%20Khan"> Irfanullah Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An extensive series of radiopharmaceuticals have been explored in order to discover a better brain tumour diagnostic agent. Tc99m labelling with cysteine and its derivatives in liposomes shows effective tagging of about 70% to 80 %. Due to microscopic size it successfully crossed the brain barrier in 2 minutes which gradually decreases in 5 to 15 minutes. HMPAO labelled with Tc99m is another important radiopharmaceutical used to study brain perfusion but it comes with a flaw that it’s only functional during epilepsy. 1, 1 ECD is purely used in Tc99m ECD formulation; because it not only tends to cross the blood brain barrier but it can be metabolized which can be easily entrapped in human brain. Radio labelling of Cysteine with Tc99m at room temperature was performed which yielded no good results. Hence cysteine derivatives with salicylaldehyde were prepared that produced about 75 % yield for ligand. In order to perform it’s radio labelling a suitable solvent DMSO was selected and physical parameters were performed. Elemental analyser produced remarkably similar results for ligand as reported in literature. IR spectra of Ligand in DMSO concluded in the absence of SH stretch and presence of N-H vibration. Thermal analysis of the ligand further suggested its decomposition pattern with no distinct curve for a melting point. Radio labelling of ligand was performed which produced excellent results giving up to 88% labelling at pH 5.0. Clinical trials using Rabbit were performed after validating the products reproducibility. The radiopharmaceutical prepared was injected into the rabbit. Dynamic as well as static study was performed under the SPECT. It showed considerable uptake in the kidneys and liver considering it suitable for the Hypatobilliary study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marcapto%20compounds" title="marcapto compounds">marcapto compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=99mTc%20-%20radiolabeling" title=" 99mTc - radiolabeling"> 99mTc - radiolabeling</a>, <a href="https://publications.waset.org/abstracts/search?q=salicylaldicysteine" title=" salicylaldicysteine"> salicylaldicysteine</a>, <a href="https://publications.waset.org/abstracts/search?q=thiozolidine" title=" thiozolidine"> thiozolidine</a> </p> <a href="https://publications.waset.org/abstracts/44640/radio-labeling-and-characterization-of-cysteine-and-its-derivatives-with-tc99m-and-their-bio-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44640.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">344</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">2355</span> Investigation of Mutagenicity and DNA Binding Properties of Metal-Free and Metallophthalocyanines Containing α-Napththolbenzein Groups on the Peripheral Positions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meltem%20Bet%C3%BCl%20Sa%C4%9Flam">Meltem Betül Sağlam</a>, <a href="https://publications.waset.org/abstracts/search?q=Halil%20I%CC%87brahim%20G%C3%BCler"> Halil İbrahim Güler</a>, <a href="https://publications.waset.org/abstracts/search?q=Aykut%20Sa%C4%9Flam"> Aykut Sağlam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, phthalocyanine compounds containing α-naphtholbenzeinunits have been synthesized.

The analysis revealed that the repertoire of possible semantic relations between the two nouns in Arabic NN compounds reproduces that in English NN compounds and that, therefore, the main difference is in headedness (right-headed in English, left-headed in Arabic). Adopting RM allows productive and idiosyncratic elements to interweave with each other naturally. Semantically transparent compounds can be stored in memory or produced and understood online, while compounds with different degrees of semantic idiosyncrasy are stored in memory. Furthermore, the predictable parts of idiosyncratic compounds are captured by general schemas. In compounds, such schemas pick out the range of possible semantic relations between the two nouns. Finally, conducting a cross-linguistic study of the systematic patterns of possible conceptual relationships between compound elements is an area worthy of further exploration. In addition, comparing and contrasting compounding in Arabic and Hebrew, especially as they are both Semitic languages, is another area that needs to be investigated thoroughly. It will help morphologists understand the extent to which Jackendoff’s repertoire of semantic relations in compounds is universal. That is, if a language as distant from English as Arabic displays a similar range of cases, this is evidence for a (relatively) universal set of relations from which individual languages may pick and choose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptual%20semantics" title="conceptual semantics">conceptual semantics</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=compounds" title=" compounds"> compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=arabic" title=" arabic"> arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=english" title=" english"> english</a> </p> <a href="https://publications.waset.org/abstracts/156865/the-conceptual-relationships-in-nn-compounds-in-arabic-compared-to-english" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156865.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">100</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">2351</span> The Relations of Volatile Compounds, Some Parameters and Consumer Preference of Commercial Fermented Milks in Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suttipong%20Phosuksirikul">Suttipong Phosuksirikul</a>, <a href="https://publications.waset.org/abstracts/search?q=Rawichar%20Chaipojjana"> Rawichar Chaipojjana</a>, <a href="https://publications.waset.org/abstracts/search?q=Arunsri%20Leejeerajumnean"> Arunsri Leejeerajumnean</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of research was to define the relations between volatile compounds, some parameters (pH, titratable acidity (TA), total soluble solid (TSS), lactic acid bacteria count) and consumer preference of commercial fermented milks. These relations tend to be used for controlling and developing new fermented milk product. Three leading commercial brands of fermented milks in Thailand were evaluated by consumers (n=71) using hedonic scale for four attributes (sweetness, sourness, flavour, and overall liking), volatile compounds using headspace-solid phase microextraction (HS-SPME) GC-MS, pH, TA, TSS and LAB count. Then the relations were analyzed by principal component analysis (PCA). The PCA data showed that all of four attributes liking scores were related to each other. They were also related to TA, TSS and volatile compounds. The related volatile compounds were mainly on fermented produced compounds including acetic acid, furanmethanol, furfural, octanoic acid and the volatiles known as artificial fruit flavour (beta pinene, limonene, vanillin, and ethyl vanillin).

The bio-compounds in the treated leaves have potential functions as antitumor, antioxidants, antihistaminic, anti-ovarian cancer, anti-inflammatory, antiarthritic, hepatoprotective, antihistaminic, haemolytic 5-α reductase inhibitor, nt, immune-stimulant, diuretic, antiandrogenic, and anaemiagenic. Alkaloids and polyphenols were retained at the rate of 81.34-98.50% using oil: aqueous mixture while aqueous recorded the rate of 33.47-41.46%. Most of the essential amino acids were retained at a rate above 90% through the aid of oil. The process is scalable and could be employed for domestic and industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20amygdalina%20leaf" title="V. amygdalina leaf">V. amygdalina leaf</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-compounds" title=" bio-compounds"> bio-compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-aqueous%20mixture" title=" oil-aqueous mixture"> oil-aqueous mixture</a>, <a href="https://publications.waset.org/abstracts/search?q=amino%20acids" title=" amino acids"> amino acids</a> </p> <a href="https://publications.waset.org/abstracts/147830/prevention-of-biocompounds-and-amino-acid-losses-in-vernonia-amygdalina-duringpost-harvest-treatment-using-hot-oil-aqueous-mixture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147830.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">146</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">2348</span> Hybrid Molecules: A Promising Approach to Design Potent Antimicrobial and Anticancer Drugs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blessing%20Atim%20Aderibigbe">Blessing Atim Aderibigbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A series of amine/ester-linked hybrid compounds containing pharmacophores, such as ursolic acid, oleanolic acid, ferrocene and bisphosphonates, were synthesized in an attempt to develop potent antibacterial and anticancer agents.

The vapor in the air can react with material in the system and generate solid uranium compounds. These solid uranium compounds continue to accumulate and attached to the production equipment and pipeline of system, which not only affects the operation reliability of production equipment and give off radiation hazard as well after system retired. Therefore, it is necessary to select a reasonable method to remove it. Through the analysis of physicochemical properties of solid uranium compounds, halogenated fluoride compounds are selected as a cleaning agent, which can remove solid uranium compounds effectively. This paper studied the related chemical reaction under the condition of static test and results show that the selection of high fluoride halogen compounds can be removed solid uranium compounds completely.

The results showed that the AO contents played a key role in the thermal stabilities of the CB/HDPE compounds—the higher the AO content, the higher the thermal stabilities. Although the CaSt-containing compounds were slightly superior to those with ZnSt in terms of the thermal stabilities, the remaining solid residue of CaSt after heated to the temperature of 600 °C (mainly calcium carbonate (CaCO3) as characterized by the X-ray diffraction (XRD) technique) seemed to catalyze the decomposition of CB in the HDPE-based compounds. Hence, the quantification of CB in the CaSt-containing compounds with a muffle furnace gave an inaccurate CB content—much lower than actual value. However, this phenomenon was negligible in the ZnSt-containing system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=stearate" title=" stearate"> stearate</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20black" title=" carbon black"> carbon black</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title=" polyethylene"> polyethylene</a> </p> <a href="https://publications.waset.org/abstracts/13017/effects-of-additives-on-thermal-decompositions-of-carbon-blackhigh-density-polyethylene-compounds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13017.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">363</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">2341</span> Separation and Purification of Oligostilbenes Using HPLC with Dereplication Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurhuda%20Manshoor">Nurhuda Manshoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Fazirulrahman%20Fathil"> Mohd Fazirulrahman Fathil</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Hakim%20Jaafar"> Muhammad Hakim Jaafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Amirul%20S.%20A.%20Jalil"> Mohd Amirul S.

This liquid oil mixture contains various kind of useful compounds such as benzoic aromatic compounds and phenolic compounds. These compounds are widely used as raw material for insecticides, dyes, medicines, perfumes, coloring matters, and many others. The coal tar was collected by pyrolysis process of coal obtained from PT Kaltim Prima Coal and Arutmin-Kalimantan. The experiments typically occurred at the atmospheric pressure in a laboratory furnace at temperatures ranging from 300 to 550oC with a heating rate of 10oC/min and a holding time of 1 hour at the pyrolysis temperature. Nitrogen gas has been used to obtain the inert condition and to carry the gaseous pyrolysis products. The pyrolysis transformed organic materials into gaseous components, small quantities of liquid, and a solid residue (coke) containing fixed amount of carbon and ash. The composition of gas which is produced from the pyrolysis is carbon monoxide, hydrogen, methane, and other hydrocarbon compounds. The gas was condensed and the liquid containing oil/tar and water was obtained. The Gas Chromatography-Mass Spectroscopy (GC-MS) was used to analyze the coal tar components.

Application of agricultural residues is mainly cheap, and available resources are receiving increased attention. Walnut green husk is one of the agricultural residues that is considered as natural compounds with biological properties because of phenolic compounds. In this study, maltodextrin 10% was used for microencapsulation of walnut green husk extract. At first, the extract was examined to consider extraction yield, total phenolic compounds, and antioxidant activation. The results showed the extraction yield of 81.43%, total phenolic compounds of 3997 [mg GAE/100 g], antioxidant activity [DPPH] of 84.85% for walnut green husk extract. Antioxidant activity is about 75%-81% and by DPPH. At the next stage, microencapsulation was done by spry-drying method. The microencapsulation efficiency was 72%-79%. The results of SEM tests confirmed this microencapsulation process. In addition, microencapsulated and free extract was more effective on gram-positive bacteria’s rather than the gram-negative ones. According to the study, walnut green husk can be used as a cheap antioxidant and antimicrobial compounds due to sufficient value of phenolic compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopolymer" title="biopolymer">biopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=microencapsulation" title=" microencapsulation"> microencapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=spray-drying" title=" spray-drying"> spray-drying</a>, <a href="https://publications.waset.org/abstracts/search?q=walnut%20green%20husk" title=" walnut green husk"> walnut green husk</a> </p> <a href="https://publications.waset.org/abstracts/98739/preparation-and-characterization-of-maltodextrin-microcapsules-containing-walnut-green-husk-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98739.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">161</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">2336</span> Pharmacological Active Compounds of Sponges and a Gorgonian Coral from the Andaman Sea, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patchara%20Pedpradab">Patchara Pedpradab</a>, <a href="https://publications.waset.org/abstracts/search?q=Kietisak%20Yoksang"> Kietisak Yoksang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosin%20Pattanamanee"> Kosin Pattanamanee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In our ongoing search for pharmacological significant of compounds from marine organisms, we investigated the active constituents of two sponges (Xestospongia sp., Halichondria sp.) and a gorgonian coral (Juncella sp.) from the Andaman Sea, Thailand.

Various parts of the plant are reported for their medicinal value due to presence of anthraquinones, phenolic compounds, emodin, β-sitosterol, and chrysophanol. Therefore a sensitive analytical procedure using UHPLC-ESI-MS/MS was developed and validated for simultaneous quantification of five phenolic compounds in leaf, stem and root extracts of Cassia tora. Rapid chromatographic separation of compounds was achieved on Acquity UHPLC BEH C18 column (50 mm×2.1 mm id, 1.7µm) column in 2.5 min. Quantification was carried out using negative electrospray ionization in multiple-reaction monitoring mode. The method was validated as per ICH guidelines and showed good linearity (r2 ≥ 0.9985) over the concentration range of 0.5-200 ng/mL. The intra- and inter-day precisions and accuracy were within RSDs ≤ 1.93% and ≤ 1.90%, respectively.

Two Trichoderma spp. were isolated from the leaves of Schefflera leucantha grown in Thailand and later identified as T. afroharzianum MFLUCC19-0090 and T. afroharzianum MFLUCC19-0091. Both in vitro and in vivo dual culture volatile assays were used to study the effects of the produced volatile compounds on mycelial growth. In vitro results showed that the volatile compounds produced by T. afroharzianum MFLUCC19-0090 significantly inhibited the growth of F. oxysporum, while the volatile compounds produced by T. afroharzianum MFLUCC19-0091 significantly inhibited the growth of F. proliferatum. The effectiveness of Trichoderma-derived volatile compounds in inhibiting the mycelial growth of the selected pathogens in the inoculated, fresh chili samples was further demonstrated in vivo. The volatile profiles of both Trichoderma spp. were characterized using gas chromatography-mass spectrometry. Seventy-three volatile compounds were detected from both strains. Among the major volatile compounds detected, phenyl ethyl alcohol was found to possess the strongest antifungal activity against both pathogens. The results support the possibility of using volatile compounds produced by T. afroharzianum MFLUCC19-0090 and T. afroharzianum MFLUCC19-0091 as alternative fumigants for preventing Fusarium rot of fresh chilies during the post-harvest period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title="antifungal activity">antifungal activity</a>, <a href="https://publications.waset.org/abstracts/search?q=biocontrol" title=" biocontrol"> biocontrol</a>, <a href="https://publications.waset.org/abstracts/search?q=endophytic%20fungi" title=" endophytic fungi"> endophytic fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=post-harvest" title=" post-harvest"> post-harvest</a> </p> <a href="https://publications.waset.org/abstracts/149845/the-biofumigation-activity-of-volatile-compounds-produced-from-trichoderma-afroharzianum-mflucc19-0090-and-trichoderma-afroharzianum-mflucc19-0091-against-fusarium-infections-in-fresh-chilies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149845.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">164</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">2331</span> Design and Facile Synthesis of New Amino Acid Derivatives with Anti-Tumor and Antimicrobial Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Sabry%20Othman">Hoda Sabry Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Randa%20Helmy%20Swellem"> Randa Helmy Swellem</a>, <a href="https://publications.waset.org/abstracts/search?q=Galal%20Abd%20El-Moein%20Nawwar"> Galal Abd El-Moein Nawwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> N-cyanoacetyl glycine is a reactive polyfunctional precursor for synthesis of new difficult accessible compounds including pyridones, thiazolopyridine and others.

VOCs emissions from both samples were collected at different stages of decomposition starting at day 0, day 1, day 3, day 5, day 7, day 10, day 12 and day 14. It was analyzed using TD-GC/MS. Findings showed that various VOCs were released during decomposition of food waste. Compounds produced were influenced by time, temperature and the physico-chemical characteristics of the compounds. The most abundant compound released was dimethyl disulfide. Potential health risk of exposure to this compound is represented by hazard ratio, HR, calculated at 1.6 x 1011. Since HR equal to or less than 1.0 is considered negligible risk, this indicates that the compound posed a potential risk to human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=volatile%20organic%20compounds" title="volatile organic compounds">volatile organic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=decomposition%20process" title=" decomposition process"> decomposition process</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20risk" title=" health risk"> health risk</a> </p> <a href="https://publications.waset.org/abstracts/39703/volatile-organic-compounds-from-decomposition-of-local-food-waste-and-potential-health-risk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39703.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">2329</span> Effect of Brewing on the Bioactive Compounds of Coffee</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ceyda%20Dadali">Ceyda Dadali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ye%C5%9Fim%20Elmaci"> Yeşim Elmaci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coffee was introduced as an economic crop during the fifteenth century; nowadays it is the most important food commodity ranking second after crude oil. Desirable sensory properties make coffee one of the most often consumed and most popular beverages in the world. The coffee preparation method has a significant effect on flavor and composition of coffee brews. Three different extraction methodologies namely decoction, infusion and pressure methods have been used for coffee brew preparation. Each of these methods is related to specific granulation (coffee grind) of coffee powder, water-coffee ratio temperature and brewing time. Coffee is a mixture of 1500 chemical compounds. Chemical composition of coffee highly depends on brewing methods, coffee bean species and roasting time-temperature. Coffee contains a wide number of very important bioactive compounds, such as diterpenes: cafestol and kahweol, alkaloids: caffeine, theobromine and trigonelline, melanoidins, phenolic compounds. The phenolic compounds of coffee include chlorogenic acids (quinyl esters of hidroxycinnamic acids), caffeic, ferulic, p-coumaric acid. In coffee caffeoylquinic acids, feruloylquinic acids and di-caffeoylquinic acids are three main groups of chlorogenic acids constitues 6% -10% of dry weight of coffee. The bioavailability of chlorogenic acids in coffee depends on the absorption and metabolization to biomarkers in individuals. Also, the interaction of coffee polyphenols with other compounds such as dietary proteins affects the biomarkers. Since bioactive composition of coffee depends on brewing methods effect of coffee brewing method on bioactive compounds of coffee will be discussed in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioactive%20compounds%20of%20coffee" title="bioactive compounds of coffee">bioactive compounds of coffee</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=coffee%20brew" title=" coffee brew"> coffee brew</a>, <a href="https://publications.waset.org/abstracts/search?q=effect%20of%20brewing" title=" effect of brewing "> effect of brewing </a> </p> <a href="https://publications.waset.org/abstracts/81620/effect-of-brewing-on-the-bioactive-compounds-of-coffee" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81620.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">196</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">2328</span> Synthesis and Characterisation of Bio-Based Acetals Derived from Eucalyptus Oil </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kirstin%20Burger">Kirstin Burger</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Watts"> Paul Watts</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicole%20Vorster"> Nicole Vorster </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green chemistry focuses on synthesis which has a low negative impact on the environment. This research focuses on synthesizing novel compounds from an all-natural Eucalyptus citriodora oil. Eight novel plasticizer compounds are synthesized and optimized using flow chemistry technology. A precursor to one novel compound can be synthesized from the lauric acid present in coconut oil. Key parameters, such as catalyst screening and loading, reaction time, temperature, residence time using flow chemistry techniques is investigated. The compounds are characterised using GC-MS, FT-IR, 1H and 13C-NMR techniques, X-ray crystallography. The efficiency of the compounds is compared to two commercial plasticizers, i.e. Dibutyl phthalate and Eastman 168. Several PVC-plasticized film formulations are produced using the bio-based novel compounds. Tensile strength, stress at fracture and percentage elongation are tested. The property of having increasing plasticizer percentage in the film formulations is investigated, ranging from 3, 6, 9 and 12%. The diastereoisomers of each compound are separated and formulated into PVC films, and differences in tensile strength are measured. Leaching tests, flexibility, and change in glass transition temperatures for PVC-plasticized films is recorded. Research objective includes using these novel compounds as a green bio-plasticizer alternative in plastic products for infants. The inhibitory effect of the compounds on six pathogens effecting infants are studied, namely; Escherichia coli, Staphylococcus aureus, Shigella sonnei, Pseudomonas putida, Salmonella choleraesuis and Klebsiella oxytoca. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-based%20compounds" title="bio-based compounds">bio-based
