Mustard greens are low in calories and fats and rich in dietary fiber. They are rich in potassium, manganese, iron, copper, calcium, magnesium and low in sodium. It is very rich in antioxidants and Phytonutrients. For the optimization of process variables (moisture content and mustard leave powder), the experiments were conducted according to central composite Face Centered Composite design of RSM. The mustard leaves powder was replaced with composite flour (a combination of rice, chickpea and corn in the ratio of 70:15:15). The extrudate was extruded in a twin screw extruder at a barrel temperature of 120°C. The independent variables were mustard leaves powder (2-10 %) and moisture content (12-20 %). Responses analyzed were bulk density, water solubility index, water absorption index, lateral expansion, hardness, antioxidant activity, total phenolic content and overall acceptability. The optimum conditions obtained were 7.19 g mustard leaves powder in 100 g premix having 16.8 % moisture content (w.b). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extrusion" title="extrusion">extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=mustard%20leaves%20powder" title=" mustard leaves powder"> mustard leaves powder</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a> </p> <a href="https://publications.waset.org/abstracts/33021/utilization-of-mustard-leaves-brassica-juncea-powder-for-the-development-of-cereal-based-extruded-snacks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33021.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">545</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">56</span> Evaluation of Non-Destructive Application to Detect Pesticide Residue on Leaf Mustard Using Spectroscopic Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazmi%20Mat%20Nawi">Nazmi Mat Nawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhamad%20Najib%20Mohamad%20Nor"> Muhamad Najib Mohamad Nor</a>, <a href="https://publications.waset.org/abstracts/search?q=Che%20Dini%20Maryani%20Ishkandar"> Che Dini Maryani Ishkandar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted to evaluate the capability of spectroscopic methods to detect the presence of pesticide residues on leaf mustard.

Fiber extraction from the stalks was the main challenge faced during the processing of stalks to ropes. Thus, an investigation on the extraction procedures of corn (<em>Zea mays</em> L.) stalk under biological and chemical retting was undertaken. Results indicated significant differences among percent fiber yield as affected by the retting methods used with values of 15.07%, 12.97%, 11.60%, and 9.01%, for dew, water, chemical (1 day after harvest and15 days after harvest), respectively, with the corresponding average extracting duration of 70, 82, 89, and 94 minutes. Physical characterization of the developed corn stalk geotextile net resulted to average mass per unit area of 806.25 g/m<sup>2</sup> and 241% water absorbing capacity. The effect of corn stalk geotextile net in mitigating soil erosion was evaluated in a laboratory experiment for 30<sup>o</sup> and 60<sup>o</sup> inclinations with three treatments: bare soil (A<sub>1</sub>), corn stalk geotextile net (A<sub>2</sub>) and combined cornstalk geotextile net and vegetation cover (A<sub>3</sub>). Results revealed that treatment A<sub>2 </sub>and A<sub>3</sub> significantly decreased sediment yield and an increase in terms of soil loss reduction efficiency.

These raw materials contain large amounts of polysaccharides, in particular hemicelluloses, celluloses, and lignins, which if efficiently extracted, can be utilised for the development of a range of added value products with potential applications in agriculture and food packaging sectors. The aim of this study was to characterise fractions extracted from sorghum bran and stalk with regards to their physicochemical properties that could determine their applicability as food-packaging materials. A sequential alkaline extraction was applied for the isolation of cellulosic, hemicellulosic and lignin fractions from sorghum stalk and bran. Lignin content, phenolic content and antioxidant capacity were also investigated in the case of the lignin fraction. Thermal analysis using differential scanning calorimetry (DSC) and X-Ray Diffraction (XRD) revealed that the glass transition temperature (T<sub>g</sub>) of cellulose fraction of the stalk was ~78.33 <sup>o</sup>C at amorphous state (~65%) and water content of ~5%. In terms of hemicellulose, the T<sub>g</sub> value of stalk was slightly lower compared to bran at amorphous state (~54%) and had less water content (~2%). It is evident that hemicelluloses generally showed a lower thermal stability compared to cellulose, probably due to their lack of crystallinity. Additionally, bran had higher arabinose-to-xylose ratio (0.82) than the stalk, a fact that indicated its low crystallinity. Furthermore, lignin fraction had T<sub>g </sub>value of ~93 <sup>o</sup>C at amorphous state (~11%). Stalk-derived lignin fraction contained more phenolic compounds (mainly consisting of <em>p</em>-coumaric and ferulic acid) and had higher lignin content and antioxidant capacity compared to bran-derived lignin fraction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%20extraction" title="alkaline extraction">alkaline extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=bran" title=" bran"> bran</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose" title=" cellulose"> cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=hemicellulose" title=" hemicellulose"> hemicellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=lignin" title=" lignin"> lignin</a>, <a href="https://publications.waset.org/abstracts/search?q=stalk" title=" stalk"> stalk</a> </p> <a href="https://publications.waset.org/abstracts/58219/characterisation-of-fractions-extracted-from-sorghum-byproducts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58219.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">299</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">51</span> Screening of Different Native Genotypes of Broadleaf Mustard against Different Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisha%20Thapa">Nisha Thapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%20Prasad%20Mainali"> Ram Prasad Mainali</a>, <a href="https://publications.waset.org/abstracts/search?q=Prakriti%20Chand"> Prakriti Chand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Broadleaf mustard is a commercialized leafy vegetable of Nepal. However, its utilization is hindered in terms of production and productivity due to the high intensity of insects, pests, and diseases causing great loss. The plant protection part of the crop’s disease and damage intensity has not been studied much from research perspectives in Nepal. The research aimed to evaluate broadleaf mustard genotypes for resistance against different diseases. A total of 35 native genotypes of broadleaf mustard were screened at weekly intervals by scoring the plants for ten weeks. Five different diseases, such as Rhizoctonia root rot, Alternaria blight, black rot, turnip mosaic virus disease, and white rust, were reported from the broad leaf mustard genotypes. Out of 35 genotypes, 23 genotypes were found with very high Rhizoctonia Root Rot severity, whereas 8 genotypes showed very high Alternaria blight severity. Likewise, 3 genotypes were found with high Black rot severity, and 1 genotype was found with very high Turnip mosaic virus disease incidence. Similarly, 2 genotypes were found to have very high White rust severity. Among the disease of national importance, Rhizoctonia root rot was found to be the most severe disease with the greatest loss. Broadleaf mustard genotypes like Rato Rayo, CO 1002, and CO 11007 showed average to the high level of field resistance; therefore, these genotypes should be used, conserved, and stored in a mustard improvement program as the disease resistance quality or susceptibility of these genotypes can be helpful for seed producing farmers, companies and other stakeholders through varietal improvement and developmental works that further aids in sustainable disease management of the vegetable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genotype" title="genotype">genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=disease%20resistance" title=" disease resistance"> disease resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhizoctonia%20root%20rot%20severity" title=" Rhizoctonia root rot severity"> Rhizoctonia root rot severity</a>, <a href="https://publications.waset.org/abstracts/search?q=varietal%20improvement" title=" varietal improvement"> varietal improvement</a> </p> <a href="https://publications.waset.org/abstracts/160605/screening-of-different-native-genotypes-of-broadleaf-mustard-against-different-diseases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160605.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">80</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">50</span> A Comparison of Sulfur Mustard Cytotoxic Effects on the Two Human Lung Origin Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Jost">P.

Except for the skin, respiratory tract is one of the important routes of exposure. The elucidation and understanding of the mechanism of toxicity of SM have been effort intensive research. The multiple targets character of SM caused cellular damage resulted in activation of many different mechanisms which contribute to cellular response and participate in the final cytopathology effect. In our present work, we compared time-dependent changes in sulfur mustard exposed adult human lung fibroblasts NHLF and lung epithelial alveolar cell line A-549. Cell viability (MTT assay, Calcein-AM assay, and xCELLigence - real-time cell analysis), apoptosis (flow cytometry), mitochondrial membrane potential (Δψm, flow cytometry), reactive oxygen species induction (DC and cell cycle distribution (flow cytometry) were studied. We observed significantly decreased mitochondrial membrane potential and subsequent induction of apoptosis correlating with decreased cellular viability in the sulfur mustard exposed cells. In low concentrations, sulfur mustard-induced S-phase cell cycle arrest, on the other hand, high concentrations, cell cycle phase distribution of sulfur mustard exposed cells resembled cell cycle phase distribution of control group, which implies nonspecific cell cycle inhibition. Epithelial cells A-549 was found as more sensible to sulfur mustard toxicity.

The following quantitative traits were studied: the number of leaves per stalk, length of leaves from the middle belt of the stalk, and yield of green leaf mass per stalk and per hectare. The trial was set up in the experimental field of Scientific Tobacco Institute - Prilep, using a randomized block design with four replications in the period 2018-2019. Traditional cultural practices were applied during the growing season of tobacco in the field. The aim of this work was to study the mode of inheritance of the quantitative traits, to detect heterosis in the F1 generation, and to assess its economic viability. Analysis of variance determined statistically significant differences in traits between parents and their hybrids in the two-year investigation. The most common way of trait inheritance is partial-dominant, then intermediate. The negative heterotic effect on the number of leaves per stalk has P 76/86 x P 66 9 7. The hybrids MV-1 x Adiyaman, P 76/86 x Basma-Djebel, P 76/86 x P 66 9 7, and Basma-Djebel x P 66 9 7 have a positive heterotic effect on the length of the leaves. Oriental hybrids, where one of the parents is variety P 66 9 7, have positive heterosis in the yield of green leaf mass per stalk. The investigation provides very useful guidance for future successive selection activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dominance" title="dominance">dominance</a>, <a href="https://publications.waset.org/abstracts/search?q=heterosis" title=" heterosis"> heterosis</a>, <a href="https://publications.waset.org/abstracts/search?q=inheritance" title=" inheritance"> inheritance</a>, <a href="https://publications.waset.org/abstracts/search?q=tobacco." title=" tobacco."> tobacco.</a> </p> <a href="https://publications.waset.org/abstracts/164376/heterothic-effect-of-some-quantitative-traits-in-f1-diallel-hybrids-of-various-tobacco-types" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164376.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">74</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">48</span> Determination of Morphological Characteristics of Brassica napus, Sinapis arvensis, Sinapis alba and Camelina sativa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bet%C3%BCl%20G%C4%B1d%C4%B1k">Betül Gıdık</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadul%20%C3%96nemli"> Fadul Önemli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Brassicaceae (Cruciferae) is an important family of plants that include many economically important vegetable production, industrial oilseed, spice, fodder crop species and energy production.

It is difficult to investigate a theoretical method for defining cutting properties of plants stalks because the cutting process is complex. Thus, it is necessary to set up an experimental approach to determine cutting parameters for a single stalk. To measure the shear force, shear energy and shear strength of plant stalk, a special impact cutting tester was fabricated. It was similar to an Izod impact cutting tester for metals but a cutting blade and data acquisition system were attached to the end of pendulum's arm. The apparatus was included four strain gages and a digital indicator to show the real-time cutting force of plant stalk. To measure the shear force and also testing the apparatus, two plants’ stalks, like buxus and privet, were selected. The samples (buxus and privet stalks) were cut under impact cutting process at four loading rates 1, 2, 3 and 4 m.s<sup>-1</sup> and three internodes fifth, tenth and fifteenth by the apparatus. At buxus cutting analysis: the minimum value of cutting energy was obtained at fifth internode and loading rate 4 m.s<sup>-1</sup> and the maximum value of shear energy was obtained at fifteenth internode and loading rate 1 m.s<sup>-1</sup>. At privet cutting analysis: the minimum value of shear consumption energy was obtained at fifth internode and loading rate: 4 m.s<sup>-1</sup> and the maximum value of shear energy was obtained at fifteenth internode and loading rate: 1 m.s<sup>-1</sup>. The statistical analysis at both plants showed that the increase of impact cutting speed would decrease the shear consumption energy and shear strength. In two scenarios, the results showed that with increase the cutting speed, shear force would decrease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buxus" title="Buxus">Buxus</a>, <a href="https://publications.waset.org/abstracts/search?q=Privet" title=" Privet"> Privet</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20cutting" title=" impact cutting"> impact cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20energy" title=" shear energy"> shear energy</a> </p> <a href="https://publications.waset.org/abstracts/109634/an-efficient-approach-for-shear-behavior-definition-of-plant-stalk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109634.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">125</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">46</span> Computational Modelling of pH-Responsive Nanovalves in Controlled-Release System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomilola%20J.%20Ajayi">Tomilola J. Ajayi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A category of nanovalves system containing the α-cyclodextrin (α-CD) ring on a stalk tethered to the pores of mesoporous silica nanoparticles (MSN) is theoretically and computationally modelled. This functions to control opening and blocking of the MSN pores for efficient targeted drug release system. Modeling of the nanovalves is based on the interaction between α-CD and the stalk (p-anisidine) in relation to pH variation. Conformational analysis was carried out prior to the formation of the inclusion complex, to find the global minimum of both neutral and protonated stalk. B3LYP/6-311G**(d, p) basis set was employed to attain all theoretically possible conformers of the stalk. Six conformers were taken into considerations, and the dihedral angle (θ) around the reference atom (N17) of the p-anisidine stalk was scanned from 0° to 360° at 5° intervals. The most stable conformer was obtained at a dihedral angle of 85.3° and was fully optimized at B3LYP/6-311G**(d, p) level of theory. The most stable conformer obtained from conformational analysis was used as the starting structure to create the inclusion complexes. 9 complexes were formed by moving the neutral guest into the α-CD cavity along the Z-axis in 1 Å stepwise while keeping the distance between dummy atom and OMe oxygen atom on the stalk restricted. The dummy atom and the carbon atoms on α-CD structure were equally restricted for orientation A (see Scheme 1). The generated structures at each step were optimized with B3LYP/6-311G**(d, p) methods to determine their energy minima. Protonation of the nitrogen atom on the stalk occurs at acidic pH, leading to unsatisfactory host-guest interaction in the nanogate; hence there is dethreading. High required interaction energy and conformational change are theoretically established to drive the release of α-CD at a certain pH. The release was found to occur between pH 5-7 which agreed with reported experimental results. In this study, we applied the theoretical model for the prediction of the experimentally observed pH-responsive nanovalves which enables blocking, and opening of mesoporous silica nanoparticles pores for targeted drug release system. Our results show that two major factors are responsible for the cargo release at acidic pH. The higher interaction energy needed for the complex/nanovalve formation to exist after protonation as well as conformational change upon protonation are driving the release due to slight pH change from 5 to 7. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanovalves" title="nanovalves">nanovalves</a>, <a href="https://publications.waset.org/abstracts/search?q=nanogate" title=" nanogate"> nanogate</a>, <a href="https://publications.waset.org/abstracts/search?q=mesoporous%20silica%20nanoparticles" title=" mesoporous silica nanoparticles"> mesoporous silica nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=cargo" title=" cargo"> cargo</a> </p> <a href="https://publications.waset.org/abstracts/99386/computational-modelling-of-ph-responsive-nanovalves-in-controlled-release-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99386.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">123</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">45</span> Detection of Mustard Traces in Food by an Official Food Safety Laboratory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clara%20Tramuta">Clara Tramuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucia%20Decastelli"> Lucia Decastelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisa%20Barcucci"> Elisa Barcucci</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Fragassi"> Sandra Fragassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Samantha%20Lupi"> Samantha Lupi</a>, <a href="https://publications.waset.org/abstracts/search?q=Enrico%20Arletti"> Enrico Arletti</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Bizzarri"> Melissa Bizzarri</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Manila%20Bianchi"> Daniela Manila Bianchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introdution: Food allergies occurs, in the Western World, 2% of adults and up to 8% of children. The protection of allergic consumers is guaranted, in Eurrope, by Regulation (EU) No 1169/2011 of the European Parliament which governs the consumer's right to information and identifies 14 food allergens to be mandatory indicated on the label. Among these, mustard is a popular spice added to enhance the flavour and taste of foods. It is frequently present as an ingredient in spice blends, marinades, salad dressings, sausages, and other products. Hypersensitivity to mustard is a public health problem since the ingestion of even low amounts can trigger severe allergic reactions. In order to protect the allergic consumer, high performance methods are required for the detection of allergenic ingredients. Food safety laboratories rely on validated methods that detect hidden allergens in food to ensure the safety and health of allergic consumers. Here we present the test results for the validation and accreditation of a Real time PCR assay (RT-PCR: SPECIALfinder MC Mustard, Generon), for the detection of mustard traces in food. Materials and Methods. The method was tested on five classes of food matrices: bakery and pastry products (chocolate cookies), meats (ragù), ready-to-eat (mixed salad), dairy products (yogurt), grains, and milling products (rice and barley flour). Blank samples were spiked starting with the mustard samples (Sinapis Alba), lyophilized and stored at -18 °C, at a concentration of 1000 ppm. Serial dilutions were then prepared to a final concentration of 0.5 ppm, using the DNA extracted by ION Force FAST (Generon) from the blank samples. The Real Time PCR reaction was performed by RT-PCR SPECIALfinder MC Mustard (Generon), using CFX96 System (BioRad). Results. Real Time PCR showed a limit of detection (LOD) of 0.5 ppm in grains and milling products, ready-to-eat, meats, bakery, pastry products, and dairy products (range Ct 25-34). To determine the exclusivity parameter of the method, the ragù matrix was contaminated with Prunus dulcis (almonds), peanut (Arachis hypogaea), Glycine max (soy), Apium graveolens (celery), Allium cepa (onion), Pisum sativum (peas), Daucus carota (carrots), and Theobroma cacao (cocoa) and no cross-reactions were observed. Discussion. In terms of sensitivity, the Real Time PCR confirmed, even in complex matrix, a LOD of 0.5 ppm in five classes of food matrices tested; these values are compatible with the current regulatory situation that does not consider, at international level, to establish a quantitative criterion for the allergen considered in this study. The Real Time PCR SPECIALfinder kit for the detection of mustard proved to be easy to use and particularly appreciated for the rapid response times considering that the amplification and detection phase has a duration of less than 50 minutes. Method accuracy was rated satisfactory for sensitivity (100%) and specificity (100%) and was fully validated and accreditated. It was found adequate for the needs of the laboratory as it met the purpose for which it was applied. This study was funded in part within a project of the Italian Ministry of Health (IZS PLV 02/19 RC). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergens" title="allergens">allergens</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=mustard" title=" mustard"> mustard</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20PCR" title=" real time PCR"> real time PCR</a> </p> <a href="https://publications.waset.org/abstracts/144177/detection-of-mustard-traces-in-food-by-an-official-food-safety-laboratory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144177.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">44</span> Toxicological Risk Analysis in Different Crops and Vegetables Exposed to High Fluoride-Contaminated Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pankaj%20Kumar">Pankaj Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite few works reported about fluoride enrichment in the groundwater, no studies have done on exposure analysis for biological components in Patan district, Gujarat, Western India.

Spinach and Mustard leaves, Cauliflower, Wheat grains, Amaranth seed, Radish, and Garlic grown in the potentially fluoride contaminated area. Result shows that the order for fluoride accumulation among different analyzed plants are spinach (63.3 mg/kg) > mustard (48.9 mg/kg) > cauliflower (41.1 mg/kg) > radish (35.7 mg/kg) > garlic (33.2 mg/kg) > amaranth seed (26.7 mg/kg) > wheat (22.5 mg/kg). Fluoride concentration was highest in leafy vegetable, whereas the lowest was in wheat grains. Finally, estimated daily intake (EDI) and hazard index (HI) were calculated for local consumers of different age group, where it was found that young people (4-15 years) are at the highest risk of fluorosis.

The soil of the experimental site was Endocalcari-Endohypogleyic Cambisol (CMg-n-w-can). The research was designed to identify the effects of dry matter and nitrogen accumulated in the above-ground biomass of various catch crops grown after winter wheat on soil mineral nitrogen variation during the autumn and spring period in the presence of intensive leaching complex. Research was done in the soil differing in humus status in the organic and sustainable cropping systems by growing various plant mixtures as catch crops: narrow-leafed lupine (Lupinus angustifolius L.) and oil radish (Raphanus sativus var. Oleifera L.), white mustard (Sinapis alba L.) and buckwheat (Fagopyrum exculentum Moench.) and white mustard as a sole crop. All crop and soil management practices have shown optimal efficiency in late autumn – stubble breaking, catch crops and straw used during the post-harvest period of the main crops, reduced Nmin migration into deeper (40–80 cm) soil layer. The greatest Nmin reduction in the 0–40 cm soil layer during the period from late autumn to early spring was identified in the sustainable cropping system having applied N30 for the promotion of straw mineralization and with no catch crops cultivation. The sustainable cropping system, having applied N30 for straw mineralization and growing white mustard in combination with buckwheat as catch crops, Nmin difference in the spring compared with its status in the autumn in the soil low and moderate in humus was lower by 70.1% and 34.2%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20nitrogen" title="soil nitrogen">soil nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=catch%20crops" title=" catch crops"> catch crops</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20and%20sustainable%20farming%20systems" title=" ecological and sustainable farming systems"> ecological and sustainable farming systems</a>, <a href="https://publications.waset.org/abstracts/search?q=Cambisol" title=" Cambisol"> Cambisol</a> </p> <a href="https://publications.waset.org/abstracts/84386/the-dynamic-of-n-in-clay-loam-cambisol-in-alternative-farming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84386.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">259</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">42</span> Correlation between Resistance to Non-Specific Inhibitor and Mammalian Pathogenicity of an Egg Adapted H9N2 Virus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chung-Young%20Lee">Chung-Young Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Se-Hee%20Ahn"> Se-Hee Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Gu%20Choi"> Jun-Gu Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Youn-Jeong%20Lee"> Youn-Jeong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyuk-Joon%20Kwon"> Hyuk-Joon Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Hong%20Kim"> Jae-Hong Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A/chicken/Korea/01310/2001 (H9N2) (01310) was passaged through embryonated chicken eggs (ECEs) by 20 times (01310-E20), and it has been used for an inactivated oil emulsion vaccine in Korea. After sequential passages, 01310-E20 showed higher pathogenicity in ECEs and acquired multiple mutations including a potential N-glycosylation at position 133 (H3 numbering) in HA and 18aa-deletion in NA stalk. To evaluate the effect of these mutations on the mammalian pathogenicity and resistance to non-specific inhibitors, we generated four PR8-derived recombinant viruses with different combinations of HA and NA from 01310-E2 and 01310-E20 (rH2N2, rH2N20, rH20N2, and rH20N20). According to our results, recombinant viruses containing 01310 E20 HA showed higher growth property in MDCK cells and higher virulence on mice than those containing 01310 E2 HA regardless of NA. The hemagglutination activity of rH20N20 was less inhibited by egg white and mouse lung extract than that of other recombinant viruses. Thus, the increased pathogenicity of 01310-E20 may be related to both higher replication efficiency and resistance to non-specific inhibitors in mice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avian%20influenza%20virus" title="avian influenza virus">avian influenza virus</a>, <a href="https://publications.waset.org/abstracts/search?q=egg%20adaptation" title=" egg adaptation"> egg adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=H9N2" title=" H9N2"> H9N2</a>, <a href="https://publications.waset.org/abstracts/search?q=N-glycosylation" title=" N-glycosylation"> N-glycosylation</a>, <a href="https://publications.waset.org/abstracts/search?q=stalk%20deletion%20of%20neuraminidase" title=" stalk deletion of neuraminidase"> stalk deletion of neuraminidase</a> </p> <a href="https://publications.waset.org/abstracts/74841/correlation-between-resistance-to-non-specific-inhibitor-and-mammalian-pathogenicity-of-an-egg-adapted-h9n2-virus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74841.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">287</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">41</span> The Preliminary Exposition of Soil Biological Activity, Microbial Diversity and Morpho-Physiological Indexes of Cucumber under Interactive Effect of Allelopathic Garlic Stalk: A Short-Term Dynamic Response in Replanted Alkaline Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Ali">Ahmad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Imran%20Ghani"> Muhammad Imran Ghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Haiyan%20Ding"> Haiyan Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhihui%20Cheng"> Zhihui Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Iqbal"> Muhammad Iqbal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aims: In recent years, protected cultivation trend, especially in the northern parts of China, spread dynamically where production area, structure, and crops diversity have expanded gradually under plastic greenhouse vegetable cropping (PGVC) system. Under this growing system, continuous monoculture with excessive synthetic fertilizers inputs are common cultivation practices frequently adopted by commercial producers. Such long-term cumulative wild exercise year after year sponsor the continuous cropping obstacles in PGVC soil, which have greatly threatened the regional soil eco-sustainability and further impose the continuous assault on soil ecological diversity leading to the exhaustion of agriculture productivity. The aim of this study was to develop new allelopathic insights by exploiting available biological resources in the favor of sustainable PGVC to illuminate the continuous obstacle factors in plastic greenhouse. Method: A greenhouse study was executed under plastic tunnel located at the Horticulture Experimental Station of the College of Horticulture, Northwest A&F University, Yangling, Shaanxi Province, one of the prominent regions for intensive commercial PGVC in China. Post-harvest garlic residues (stalk, leaves) mechanically smashed, homogenized into powder size and incorporated at the ratio of 1:100; 3:100; 5:100 as a soil amendment in a replanted soil that have been used for continuous cucumber monoculture for 7 years (annually double cropping system in a greenhouse). Results: Incorporated C-rich garlic stalk significantly influenced the soil condition through various ways; organic matter decomposition and mineralization, moderately adjusted the soil pH, enhanced the soil nutrient availability, increased enzymatic activities, and promoted 20% more cucumber yield in short-time. Using Illumina MiSeq sequencing analysis of bacterial 16S rRNA and fungal 18S rDNA genes, the current study revealed that addition of garlic stalk/residue could also improve the microbial abundance and community composition in extensively exploited soil, and contributed in soil functionality, caused prosper changes in soil characteristics, reinforced to good crop yield. Conclusion: Our study provided evidence that addition of garlic stalk as soil fertility amendment is a feasible, cost-effective and efficient resource utilization way for renovation of degraded soil health, ameliorate soil quality components and improve ecological environment in short duration. Our study may provide a better scientific understanding for efficient crop residue management typically from allelopathic source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=garlic%20stalk" title="garlic stalk">garlic stalk</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20community%20dynamics" title=" microbial community dynamics"> microbial community dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20growth" title=" plant growth"> plant growth</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20amendment" title=" soil amendment"> soil amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-plant%20system" title=" soil-plant system"> soil-plant system</a> </p> <a href="https://publications.waset.org/abstracts/93430/the-preliminary-exposition-of-soil-biological-activity-microbial-diversity-and-morpho-physiological-indexes-of-cucumber-under-interactive-effect-of-allelopathic-garlic-stalk-a-short-term-dynamic-response-in-replanted-alkaline-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93430.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">134</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">40</span> Micromorphological Traits and Essential Oil Contents of Valeriana tuberosa L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nada%20Bezi%C4%87">Nada Bezić</a>, <a href="https://publications.waset.org/abstracts/search?q=Valerija%20Dunki%C4%87"> Valerija Dunkić</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonija%20Markovina"> Antonija Markovina</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirko%20Ru%C5%A1%C4%87i%C4%87"> Mirko Rušćić </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Valeriana is a genus of the well-known medicinal plant of Valerianacea family and growing wild in the sub-Mediterranean area.

Suitability of the pure cultures like Klebsiela pneumonia, C. freundii, B. coagulan, etc. and mixed acidogenic cultures for the biohydrogen production was already studied. The characteristics of organic wastes play a critical role in biohydrogen production. The choice of an appropriate combination of complementary organic wastes can vastly improve the bioenergy generation besides achieving the significant cost reduction. Suitability and economic viability of using the groundnut deoiled cake (GDOC), mustard deoiled cake (MDOC), distillers’ dried grain with soluble (DDGS) and algal biomass (AB) as a co-substrate were studied for a biohythane production. Results show that maximum gaseous energy of 20.7, 9.3, 16.7 and 15.6 % was recovered using GDOC, MDOC, DDGS and AB in the two stage biohythane production, respectively. Both GDOC and DDGS were found to be better co-substrates as compared to MDOC and AB in terms of hythane production, respectively. The maximum cumulative hydrogen and methane production of 150 and 64 mmol/L were achieved using GDOC. Further, 98 % reduction in substrate input cost (SIC) was achieved using the co-supplementation procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biohythane" title="Biohythane">Biohythane</a>, <a href="https://publications.waset.org/abstracts/search?q=algal%20biomass" title=" algal biomass"> algal biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=distillers%E2%80%99%20dried%20grain%20with%20soluble%20%28DDGS%29" title=" distillers’ dried grain with soluble (DDGS)"> distillers’ dried grain with soluble (DDGS)</a>, <a href="https://publications.waset.org/abstracts/search?q=groundnut%20deoiled%20cake%20%28GDOC%29" title=" groundnut deoiled cake (GDOC)"> groundnut deoiled cake (GDOC)</a>, <a href="https://publications.waset.org/abstracts/search?q=mustard%20deoiled%20cake%20%28MDOC%29" title=" mustard deoiled cake (MDOC)"> mustard deoiled cake (MDOC)</a> </p> <a href="https://publications.waset.org/abstracts/71721/potentiality-of-biohythane-process-for-the-gaseous-energy-recovery-from-organic-wastes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71721.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">200</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">38</span> In vitro Analysis of the Effect of Supplementation Oils on Conjugated Linoleic Acid Production by Butyvibrio Fibrisolvense</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20D.%20Ravindra">B.

Kathirvelan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Some micronutrients in food (milk and meat), called ‘functional food components’ exert beneficial effects other than their routine nutrient function and conjugated linoleic acid (CLA) is an unsaturated fatty acid of ruminant origin, an example of this category. However, recently the fear of hypercholesterolemia due to saturated fats has led to the avoidance of dietary fat especially of animal origin despite its advantages such as lowering blood cholesterol, immuno-modulation and anticarcinogenic property due to the presence of CLA. The dietary increase of linoleic acid (LA) and linolenic acid (LNA) is one of the feeding strategies for increasing the CLA concentration in milk. Butyrivibrio fibrisolvens is the one potential rumen bacteria, which has high potential to isomerize LA to CLA. The study was conducted to screen the different oils for CLA production, selected based on their LA concentration. Butyrivibrio fibrisolvens culture (strain 49, MZ3, 30/10) were isolated from the rumen liquor of fistulated Buffalo (age ≈ 3 years; weight ≈ 250 kg) were used in in-vitro experiments, further work was carried out with three oils viz., sunflower, mustard and soybean oil at different concentration (0.05, 0.1, 0.15, 0.2, 0.25 and 0.3 g/L of media) to study the growth of bacteria and CLA production at different incubation period (0, 8, 12, 18, 24, 48, 72 h). In the present study, growth of the bacteria was decreased linearly with increase in concentration of three oils. However, highest decrease in growth was recorded at the concentration of 0.30 g of three oils per litre of the media. Highest CLA production was 51.96, 42.08 and 25.60 µg/ml at 0.25 g and it decreased to 48.19, 39.35 and 23.41 µg/ml at 0.3 g supplementation of sunflower, soybean, and mustard oil per litre of the media, respectively at 18 h incubation period. The present study indicates the Butyrivibrio fibrisolvens bacteria involves in the biohydrogenation process, and LA rich sunflower meal can be used to improve the CLA production in rumen and thereby increasing the CLA concentration of milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Butyrivibrio%20fibrisolvens" title="Butyrivibrio fibrisolvens">Butyrivibrio fibrisolvens</a>, <a href="https://publications.waset.org/abstracts/search?q=CLA" title=" CLA"> CLA</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower%20oil" title=" sunflower oil"> sunflower oil</a> </p> <a href="https://publications.waset.org/abstracts/79780/in-vitro-analysis-of-the-effect-of-supplementation-oils-on-conjugated-linoleic-acid-production-by-butyvibrio-fibrisolvense" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79780.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">374</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">37</span> Performance of Growing Rahaji Bulls Fed Diets Containing Similar Concentrates and Different Crop Residues in a Semi-Arid Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Husaini%20Sama">Husaini Sama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was conducted, in a 120 - day’s trial, to monitor the performance of growing Rahaji bulls fed different crop residues.

It serves as a source of power (hydroelectricity), irrigation, and flood control. The potential of this lake is getting worse by the presence of aquatic plants (Eichhornia crassipes) that grows wild, and it can make the lake covered by the cumulation of rotten E. crassipes. This cumulation causes the sediment formation which has high organic material composition. Sediment formation will be lead into a shallowing of the lake and affect water’s quality. The deposition of organic material produces methane gas and hydrogen sulfide, which in rain would turn the water muddy and decompose. Decomposition occuring in the water due to microbe activity in lake's water. The shallowing of Rawa Pening Lake not only will physically can reduce water discharge, but it also has ecologically major impact on water organism. The condition of Rawa Pening Lake peats can not be considered as unimportant issue. One of the solutions that can be applied is by using the peats as a compound materials on growing horticultural crops because the organic materials content on the mineral soil is low, particularly on an old soils. The horticultural crops required organic materials for growth promoting. The horticultural crops that use in this research is mustard cabbage (Brassica sp.). Using Rawa Pening's peats as the medium of plants with high organic materials that also can ameliorate soil’s physical properties, and indirectly serves as soil conditioner. Research will be focus on the peat’s contents and mustard cabbage product’s content. The contents that will be examined is the N-available, Ca, Mg, K, P, and C-organic. The analysis of Ca, Mg, and K is use soil base saturation measurement method and extracting soil is use NH4OAC solution.

A study was carried out to evaluate the physical characteristics of chopped date palm stalks (fronds and leaflets). These properties are necessary to apply normal design procedures such as pneumatic conveying, fluidization, drying, and combustion. The mechanical treatment by cutting, crushing or chopping and briquetting processes are the primary step and the suitable solution for solving this problem and recycling these residuals to be transformed into useful products. So the aim of the present work to get a high quality for agriculture residues such as date palm stalks (fronds), date palm leaflets briquettes. The results obtained from measuring the mechanical properties (average shear and compressive strength) for date palm stalks at different moisture content (12.63, 33.21 and 60.54%) was (6.4, 4.7 and 3.21MPa) and (3.8, 3.18 and 2.86MPa) respectively. The modulus of elasticity and toughness were evaluated as a function of moisture content. As the moisture content of the stalk regions increased the modulus of elasticity and toughness decreased indicating a reduction in the brittleness of the stalk regions. Chopped date palm stalks (palm fronds), date palm leaflets having moisture content of 8, 10 and 12% and 8, 10 and 12.8% w.b. were dandified into briquettes without binder and with binder (urea-formaldehyde) using a screw press machine. Quality properties for briquettes were durability, compression ratio hardness, bulk density, compression ratio, resiliency, water resistance and gases emission.

D. farinae is often swarm over powder products (e.g. wheat flour), because it feeds on starch or protein that are included in them. Eating powder products which are mixed D.farinae causes various allergic symptoms. Therefore, the creation of food additive agents with high safety and control of mite effect is required. Fatty acid salts and spices are known that have pesticidal activities. This study describes the effects of fatty acid salts and spices against Dermatophagoides farinae. Materials and Methods: Potassium salts of 9 fatty acids (C4:0, C6:0, C8:0, C10:0, C12:0, C14:0, C18:1, C18:2, C18:3) were prepared by mixing the fatty acid with the appropriate amount of KOH solution to a concentration of 175 mM and pH 10.5. C12Cu and C12Zn were selected as other fatty acid salts. Cayenne pepper, habanero, Japanese pepper, mustard, jalapeno pepper, curry aroma and cinnamon were selected as spices. D. farina, have been cultured in laboratory. To rear the mites, double-soled dishes containing of sterilized food were put on the big plastic container (30.0 × 20.0 × 20.0cm) which had 100% ammonium nitrate solution in the bottom. Plastic container was placed on incubator at 25 °C and 64 % relative humidity (RH) under dark condition. Sterilized food composed of dried bonito flakes and dried yeast (Ebios), 1:1 by weight. The antiproliferative method, sample and medium culture were mixed in double-soled dish and kept at 25 °C and 64 % RH. Decrease rates were determined 1 week and 4 week after treatment under microscope. D. farina was considered to be dead if appendages did not move when prodded with a pin. Results and Conclusions: The results show that the fatty acids potassium showed no antiproliferative effects against D. farinae. On the other hand, Japanese pepper, mustard, curry aroma and cinnamon were effective to decrease propagative rate (over 80 %) after treatment for 1 week against D. farina. Japanese pepper, curry aroma and cinnamon were effective to decrease propagative rate (approximately 100 %) after treatment for 4 weeks against D. farina. Especially, Japanese pepper and cinnamon showed the fasted and the most consecutive antiproliferative effects. These results indicate that Japanese pepper and cinnamon have high antiproliferative effects against D. farina and suggest spices will be used as a food additive agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid%20salts" title="fatty acid salts">fatty acid salts</a>, <a href="https://publications.waset.org/abstracts/search?q=spices" title=" spices"> spices</a>, <a href="https://publications.waset.org/abstracts/search?q=antiproliferative%20effects" title=" antiproliferative effects"> antiproliferative effects</a>, <a href="https://publications.waset.org/abstracts/search?q=dermatophagoides%20farinae" title=" dermatophagoides farinae"> dermatophagoides farinae</a> </p> <a href="https://publications.waset.org/abstracts/49384/effects-of-fatty-acid-salts-and-spices-on-dermatophagoides-farinae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49384.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">234</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">33</span> Social Data Aggregator and Locator of Knowledge (STALK)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashmi%20Raghunandan">Rashmi Raghunandan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjana%20Shankar"> Sanjana Shankar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakshitha%20K.%20Bhat"> Rakshitha K.

This project will greatly reduce the need for unnecessary manual analysis of large and diverse social media profiles by filtering out and combining the useful information from various social media profiles, eliminating irrelevant data. It differs from the existing social media aggregators in that it does not provide a consolidated view of various profiles. Instead, it provides consolidated INFORMATION derived from the subject’s posts and other activities. It also allows analysis over multiple profiles and analytics based on several profiles. We strive to provide a query system to provide a natural language answer to questions when a user does not wish to go through the entire profile. The information provided can be filtered according to the different use cases it is used for. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20network" title="social network">social network</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook" title=" Facebook"> Facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=Linkedin" title=" Linkedin"> Linkedin</a>, <a href="https://publications.waset.org/abstracts/search?q=git" title=" git"> git</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a> </p> <a href="https://publications.waset.org/abstracts/37509/social-data-aggregator-and-locator-of-knowledge-stalk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37509.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">444</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">32</span> The Environmental Impact of Wireless Technologies in Nigeria: An Overview of the IoT and 5G Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Powei%20Happiness%20Kerry">Powei Happiness Kerry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introducing wireless technologies in Nigeria have improved the quality of lives of Nigerians, however, not everyone sees it in that light.

Some of the proven biological activities of mushroom extracts are antioxidant, antimicrobial, immunomodulatory, cholesterol lowering activity by inhibiting a key cholesterol metabolism enzyme i.e. 3-hydroxy-3-methyl-glutaryl CoA reductase (HMGCR), angiotensin I-converting enzyme (ACE) inhibition. Application of novel extraction technologies like pulsed electric field (PEF) and high power ultrasound offers clean, green, faster and efficient extraction alternatives with enhanced and good quality extracts. Sequential PEF followed by ultrasound assisted extraction (UAE) were applied to recover bioactive enriched fractions from industrial white button mushroom (Agaricus bisporus) stalk waste using environmentally friendly and GRAS solvents i.e. water and water/ethanol combinations. The PEF treatment was carried out at 60% output voltage, 2 Hz frequency for 500 pulses of 20 microseconds pulse width, using KCl salt solution of 0.6 mS/cm conductivity by the placing 35g of chopped fresh mushroom stalks and 25g of salt solution in the 4x4x4cm3 treatment chamber. Sequential UAE was carried out on the PEF pre-treated samples using ultrasonic-water-bath (USB) of three frequencies (25 KHz, 35 KHz and 45 KHz) for various treatment times (15-120 min) at 80°C. Individual treatment using either PEF or UAE were also investigation to compare the effect of each treatment along with the combined effect on the recovery and bioactivity of the crude extracts. The freeze dried mushroom stalk powder was characterised for proximate compositional parameters (dry weight basis) showing 64.11% total carbohydrate, 19.12% total protein, 7.21% total fat, 31.2% total dietary fiber, 7.9% chitin (as glucosamine equivalent) and 1.02% β-glucan content. The total phenolic contents (TPC) were determined by the Folin-Ciocalteu procedure and expressed as gallic-acid-equivalents (GAE). The antioxidant properties were ascertained using DPPH and FRAP assays and expressed as trolox-equivalents (TE). HMGCR activity and molecular mass of β-glucans will be measured using the commercial HMG-CoA Reductase Assay kit (Sigma-Aldrich) and size exclusion chromatography (HPLC-SEC), respectively. Effects of PEF, UAE and their combination on the antioxidant capacity, HMGCR inhibition and β-glucans content will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B2-glucan" title="β-glucan">β-glucan</a>, <a href="https://publications.waset.org/abstracts/search?q=mushroom%20stalks" title=" mushroom stalks"> mushroom stalks</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed%20electric%20field%20%28PEF%29" title=" pulsed electric field (PEF)"> pulsed electric field (PEF)</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound%20assisted%20extraction%20%28UAE%29" title=" ultrasound assisted extraction (UAE)"> ultrasound assisted extraction (UAE)</a> </p> <a href="https://publications.waset.org/abstracts/65769/sequential-pulsed-electric-field-and-ultrasound-assisted-extraction-of-bioactive-enriched-fractions-from-button-mushroom-stalks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65769.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">292</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">30</span> Improving Utilization of Sugarcane by Replacing Ordinary Propagation Material with Small Chips of Sugarcane Planted in Paper Pots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Garcia">C.

This would be a more sustainable solution, reducing labor costs and avoiding pollution with plastic. We compared the establishment of plants from nodes taken from three different part of the sugarcane plant. The nodes were planted in plastic and paper pots. There was no significant difference between plants established in the two pot types. Nodes from different part of the stalk had different sprouting capacity. Nodes from the top parts sprouted significantly better than nodes taken from the middle or nodes taken closed to the ground in two experiments.

In addition, the increasing development of technologies for energy biomass conversion parallel to the advancement of research in biotechnology and engineering has enabled new opportunities for exploitation of biomass. Agricultural residues offer great potential for energy use, and Brazil is in a prominent position in the production and export of agricultural products such as banana and rice. Despite the economic importance of the growth prospects of these activities and the increasing of the agricultural waste, they are rarely explored for energy and production of new materials. Brazil products almost 10.5 million tons/year of rice husk and 26.8 million tons/year of banana stem. Thereby, the aim of this study was to analysis the potential of biomass residues for energy production and applications in new materials. Rice husk (specify the type) and banana stem (specify the type) were characterized by physicochemical analyses using the following parameters: organic carbon, nitrogen (NTK), proximate analyses, FT-IR spectroscopy, thermogravimetric analyses (TG), calorific values and silica content. Rice husk and banana stem presented attractive superior calorific (from 11.5 to 13.7MJ/kg), and they may be compared to vegetal coal (21.25 MJ/kg). These results are due to the high organic matter content. According to the proximate analysis, biomass has high carbon content (fixed and volatile) and low moisture and ash content. In addition, data obtained by Walkley–Black method point out that most of the carbon present in the rice husk (50.5 wt%) and in banana stalk (35.5 wt%) should be understood as organic carbon (readily oxidizable). Organic matter was also detected by Kjeldahl method which gives the values of nitrogen (especially on the organic form) for both residues: 3.8 and 4.7 g/kg of rice husk and banana stem respectively. TG and DSC analyses support the previous results, as they can provide information about the thermal stability of the samples allowing a correlation between thermal behavior and chemical composition. According to the thermogravimetric curves, there were two main stages of mass-losses. The first and smaller one occurred below 100 °C, which was suitable for water losses and the second event occurred between 200 and 500 °C which indicates decomposition of the organic matter. At this broad peak, the main loss was between 250-350 °C, and it is because of sugar decomposition (components readily oxidizable). Above 350 °C, mass loss of the biomass may be associated with lignin decomposition. Spectroscopic characterization just provided qualitative information about the organic matter, but spectra have shown absorption bands around 1030 cm-1 which may be identified as species containing silicon. This result is expected for the rice husk and deserves further investigation to the stalk of banana, as it can bring a different perspective for this biomass residue. <p
