Nevertheless, immobilized enzymes generally suffer from reduced activities compared to their soluble counterparts. One major factor leading to activity loss is the intrinsic hydrophobic property of the supporting material surface, which could result in the conformational change/confinement of enzymes. We report a strategy of utilizing flexible poly (ethylene oxide) (PEO) moieties as to improve the surface hydrophilicity of solid supports used for enzyme immobilization. DNA modifying enzymes were covalently conjugated to PEO-coated magnetic-beads. Kinetics studies proved that the activities of the covalently-immobilized DNA modifying enzymes were greatly enhanced by the PEO modification on the bead surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immobilized%20enzymes" title="immobilized enzymes">immobilized enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=biocatalysis" title=" biocatalysis"> biocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28ethylene%20oxide%29" title=" poly(ethylene oxide)"> poly(ethylene oxide)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20modification" title=" surface modification"> surface modification</a> </p> <a href="https://publications.waset.org/abstracts/79716/improvement-on-the-specific-activities-of-immobilized-enzymes-by-polyethylene-oxide-surface-modification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79716.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">308</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">1026</span> Video Stabilization Using Feature Point Matching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shamsundar%20Kulkarni">Shamsundar Kulkarni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Video capturing by non-professionals will lead to unanticipated effects.

Due to its intrinsic rail-to-rail voltage transition, the input sides are inevitably disturbed. It can possible disturb the stabilities of the reference voltage levels.

The overall objective of this research is a strain improvement technology for efficient industrial enzymes production. The new way of filamentous fungi cultivation method has been developed. Such technology prolong producers’ cultivation period up to 60 days and create the opportunity to obtain enzymes repeatedly in every 2-3 days of fungal cultivation. This method is based on immobilizing enzymes producers with solid support in submerged conditions of growth. Immobilizing has a range of advantages: Decreasing the price of the final product, absence of foreign substances, controlled process of enzyme-genesis, ability of various enzymes simultaneous production, etc. Design of proposed technology gives the opportunity to increase the activity of immobilized cells culture filtrate comparing to free cells, growing in periodic culture conditions.

Peat is considered to be in the category of problematic soil, which is not suitable for construction, due to its high compressibility, high moisture content, low shear strength, and low bearing capacity. Since this kind of soil is generally found in many countries and different regions, finding desirable techniques for stabilization of peat is absolutely essential. The purpose of this paper is to review the various techniques applied for stabilizing peat soil and discuss outcomes of its improved mechanical parameters and strength properties. Recognizing characterization of stabilized peat is one of the most significant factors for architectural structures; as a consequence, various strategies for stabilization of this susceptible soil have been examined based on the depth of peat deposit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peat%20soil" title="peat soil">peat soil</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=depth" title=" depth"> depth</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a>, <a href="https://publications.waset.org/abstracts/search?q=unconfined%20compressive%20strength%20%28USC%29" title=" unconfined compressive strength (USC)"> unconfined compressive strength (USC)</a> </p> <a href="https://publications.waset.org/abstracts/36737/peat-soil-stabilization-methods-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36737.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">573</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">1021</span> The Increasing of Unconfined Compression Strength of Clay Soils Stabilized with Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%CC%87%20Si%CC%87nan%20So%C4%9Fanci">Ali̇ Si̇nan Soğanci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cement stabilization is one of the ground improvement method applied worldwide to increase the strength of clayey soils. The using of cement has got lots of advantages compared to other stabilization methods. Cement stabilization can be done quickly, the cost is low and creates a more durable structure with the soil. Cement can be used in the treatment of a wide variety of soils. The best results of the cement stabilization were seen on silts as well as coarse-grained soils. In this study, blocks of clay were taken from the Apa-Hotamış conveyance channel route which is 125km long will be built in Konya that take the water with 70m3/sec from Mavi tunnel to Hotamış storage. Firstly, the index properties of clay samples were determined according to the Unified Soil Classification System. The experimental program was carried out on compacted soil specimens with 0%, 7 %, 15% and 30 % cement additives and the results of unconfined compression strength were discussed. The results of unconfined compression tests indicated an increase in strength with increasing cement content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cement%20stabilization" title="cement stabilization">cement stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=unconfined%20compression%20test" title=" unconfined compression test"> unconfined compression test</a>, <a href="https://publications.waset.org/abstracts/search?q=clayey%20soils" title=" clayey soils"> clayey soils</a>, <a href="https://publications.waset.org/abstracts/search?q=unified%20soil%20classification%20system." title=" unified soil classification system."> unified soil classification system.</a> </p> <a href="https://publications.waset.org/abstracts/35636/the-increasing-of-unconfined-compression-strength-of-clay-soils-stabilized-with-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35636.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">422</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">1020</span> The Effect of Scapular Stabilization Exercises on Chronic Neck Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amany%20Mohamed">Amany Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Balbaa"> Alaa Balbaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdoline%20Mishel"> Magdoline Mishel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Pain in the neck or scapular region is one of the most frequent symptoms in cervical radiculopathy, which is commonly caused by degenerative process in the spine.

The objectives are to establish a nexus between cation exchange capacity of the soil, the alkaline forming compounds in CCA and percentage CCA addition to soil beyond which no more improvement in strength properties can be achieved; and to propose feasible chemical reactions to explain the chemical stabilization of the lateritic soil with CCA alone. The lateritic soil, as well as CCA of pozzolanic quality Class C were separately analysed for their metallic oxide composition using the X-Ray Fluorescence technique. The cation exchange capacity (CEC) of the soil and the CCA were computed theoretically using the percentage composition of the base cations Ca<sup>2+</sup>, Mg<sup>2+</sup> K<sup>+</sup> and Na<sup>2+</sup> as 1.48 meq/100 g and 61.67 meq/100 g respectively, thus indicating a ratio of 0.024 or 2.4%. This figure, taken as the theoretical amount required to just fill up the exchangeable sites of the clay molecules, compares well with the laboratory observation of 1.5% for the optimum level of CCA addition to lateritic soil. The paper went on to present chemical reaction equations between the alkaline earth metals in the CCA and the silica in the lateritic soil to form silicates, thereby proposing an extension of the theory of mechanism of soil stabilization to cover chemical stabilization with pozzolanic ash only. The paper concluded by recommending further research on the molecular structure of soils stabilized with pozzolanic waste ash alone, with a view to confirming the chemical equations advanced in the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cation%20exchange%20capacity" title="cation exchange capacity">cation exchange capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20cob%20ash" title=" corn cob ash"> corn cob ash</a>, <a href="https://publications.waset.org/abstracts/search?q=lateritic%20soil" title=" lateritic soil"> lateritic soil</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20stabilization" title=" soil stabilization"> soil stabilization</a> </p> <a href="https://publications.waset.org/abstracts/43830/physicochemistry-of-pozzolanic-stabilization-of-a-class-a-2-7-lateritic-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43830.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">248</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">1017</span> Comparative Analysis of Enzyme Activities Concerned in Decomposition of Toluene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayuko%20Itsuki">Ayuko Itsuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Sachiyo%20Aburatani"> Sachiyo Aburatani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, pollutions of the environment by toxic substances become a serious problem. While there are many methods of environmental clean-up, the methods by microorganisms are considered to be reasonable and safety for environment. Compost is known that it catabolize the meladorous substancess in its production process, however the mechanism of its catabolizing system is not known yet. In the catabolization process, organic matters turn into inorganic by the released enzymes from lots of microorganisms which live in compost. In other words, the cooperative of activated enzymes in the compost decomposes malodorous substances. Thus, clarifying the interaction among enzymes is important for revealing the catabolizing system of meladorous substance in compost. In this study, we utilized statistical method to infer the interaction among enzymes. We developed a method which combined partial correlation with cross correlation to estimate the relevance between enzymes especially from time series data of few variables. Because of using cross correlation, we can estimate not only the associative structure but also the reaction pathway. We applied the developed method to the enzyme measured data and estimated an interaction among the enzymes in decomposition mechanism of toluene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enzyme%20activities" title="enzyme activities">enzyme activities</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20analysis" title=" comparative analysis"> comparative analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=compost" title=" compost"> compost</a>, <a href="https://publications.waset.org/abstracts/search?q=toluene" title=" toluene"> toluene</a> </p> <a href="https://publications.waset.org/abstracts/2728/comparative-analysis-of-enzyme-activities-concerned-in-decomposition-of-toluene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2728.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">273</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">1016</span> Success Rate of Endotracheal Intubation Using Inline Stabilization with and without Cervical Hard Collar; A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Welawat%20Tienpratarn">Welawat Tienpratarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaiyaporn%20Yuksen"> Chaiyaporn Yuksen</a>, <a href="https://publications.waset.org/abstracts/search?q=Kasamon%20Aramvanitch"> Kasamon Aramvanitch</a>, <a href="https://publications.waset.org/abstracts/search?q=Karn%20Suttapanit"> Karn Suttapanit</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Mankong"> Yahya Mankong</a>, <a href="https://publications.waset.org/abstracts/search?q=Nussareen%20Yaemluksanalert"> Nussareen Yaemluksanalert</a>, <a href="https://publications.waset.org/abstracts/search?q=Sansanee%20Meesawad"> Sansanee Meesawad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction : Application of a rigid cervical collar may interfere with the laryngeal view, and potentially lead to failed endotracheal intubation (ETI). This study aimed to compare intubation success rates while performing inline stabilization with and without cervical hard collar. Methods : This randomized prospective comparative study included paramedics working in the Department of Emergency Medicine, Ramathibodi Hospital, Mahidol University, Bangkok, Thailand to compare the success rates of endotracheal intubation on manikin using inline stabilization with and without cervical hard collar. Results : 125 participants were evaluated; 63 in the rigid cervical collar and 62 in the non-cervical hard collar group. The rate of successful intubation was significantly higher using manual stabilization without cervical hard collar (61 (96.8%) vs. 55 (88.7%); p=0.048). The time required to successfully perform intubation was also shorter, with manual stabilization only (14.1 ±20.9 vs. 18.9±29.0; p = 0.081). Conclusion : It seems that, removal of the rigid cervical collar during ETI in patients with suspected traumatic spine injury could increase the intubation success rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ntubation" title="ntubation">ntubation</a>, <a href="https://publications.waset.org/abstracts/search?q=Intratracheal" title="Intratracheal">Intratracheal</a>, <a href="https://publications.waset.org/abstracts/search?q=Spinal%20Injuries" title="Spinal Injuries">Spinal Injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=Multiple%20trauma" title="Multiple trauma">Multiple trauma</a> </p> <a href="https://publications.waset.org/abstracts/142888/success-rate-of-endotracheal-intubation-using-inline-stabilization-with-and-without-cervical-hard-collar-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142888.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">126</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">1015</span> Production of Lignocellulosic Enzymes by Bacillus safensis LCX Using Agro-Food Wastes in Solid State Fermentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abeer%20A.%20Q.%20Ahmed">Abeer A.

Lignocellulose, such as agro-food wastes, is a suitable equivalent to petroleum for fine chemicals and fuels production. The complex structure of lignocellulose, however, requires a variety of enzymes in order to degrade its components into their respective building blocks that can be used further for the production of various value added products. This study aimed to isolate bacterial strain with the ability to produce a variety of lignocellulosic enzymes. One bacterial isolate was identified by 16S rRNA gene sequencing and phylogenetic analysis as Bacillus safensis LCX found to have CMCase, xylanase, manganese peroxidase, lignin peroxidase, and laccase activities. The enzymes production was induced by growing Bacillus safensis LCX in solid state fermentation using wheat straw, wheat bran, and corn stover. The activities of enzymes were determined by specific colorimetric assays. This study presents Bacillus safensis LCX as a promising source for lignocellulosic enzymes. These findings can extend the knowledge on agro-food wastes valorization strategies toward a sustainable production of fuels and chemicals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20safensis%20LCX" title="Bacillus safensis LCX">Bacillus safensis LCX</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20valued%20chemicals" title=" high valued chemicals"> high valued chemicals</a>, <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20enzymes" title=" lignocellulosic enzymes"> lignocellulosic enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20fermentation" title=" solid state fermentation"> solid state fermentation</a> </p> <a href="https://publications.waset.org/abstracts/64985/production-of-lignocellulosic-enzymes-by-bacillus-safensis-lcx-using-agro-food-wastes-in-solid-state-fermentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64985.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1014</span> Influence of Heliotropium Undulatum on Hepatic Glutathione Conjugating Enzymes System in Acetylhydrazide-Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Ameddah">S.

They have excellent features like high activity, specificity and selectivity, and can catalyze under mild and environment friendly conditions. Epoxy-activated supports are almost-ideal ones to perform very easy immobilization of proteins and enzymes at both laboratory and industrial scale. The activated epoxy supports (chitosan/alginate, Eupergit C) may be very suitable to achieve the multipoint covalent attachment of proteins and enzymes, therefore, to stabilize their three-dimensional structure. The enzyme is firstly covalently immobilized under conditions pH 7.0 and 10.0. The remaining groups of the support are blocked to stop additional interaction between the enzyme and support by mercaptoethanol or Triton X-100. The results show support allowed obtaining biocatalysts with high immobilized protein amount and hydrolytic activity. The immobilization of lipases on epoxy support may be considered as attractive tool for obtaining highly active biocatalysts to be used in both aqueous and anhydrous aqueous media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immobilization%20of%20enzymes" title="immobilization of enzymes">immobilization of enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20supports" title=" epoxy supports"> epoxy supports</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20multipoint%20covalent%20attachment" title=" enzyme multipoint covalent attachment"> enzyme multipoint covalent attachment</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20lipases" title=" microbial lipases"> microbial lipases</a> </p> <a href="https://publications.waset.org/abstracts/9260/immobilization-of-enzymes-and-proteins-on-epoxy-activated-supports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9260.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">388</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">1010</span> Effect of Cement Amount on California Bearing Ratio Values of Different Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayse%20Pekrioglu%20Balkis">Ayse Pekrioglu Balkis</a>, <a href="https://publications.waset.org/abstracts/search?q=Sawash%20Mecid"> Sawash Mecid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to continued growth and rapid development of road construction in worldwide, road sub-layers consist of soil layers, therefore, identification and recognition of type of soil and soil behavior in different condition help to us to select soil according to specification and engineering characteristic, also if necessary sometimes stabilize the soil and treat undesirable properties of soils by adding materials such as bitumen, lime, cement, etc. If the soil beneath the road is not done according to the standards and construction will need more construction time. In this case, a large part of soil should be removed, transported and sometimes deposited. Then purchased sand and gravel is transported to the site and full depth filled and compacted. Stabilization by cement or other treats gives an opportunity to use the existing soil as a base material instead of removing it and purchasing and transporting better fill materials. Classification of soil according to AASHTOO system and USCS help engineers to anticipate soil behavior and select best treatment method. In this study soil classification and the relation between soil classification and stabilization method is discussed, cement stabilization with different percentages have been selected for soil treatment based on NCHRP. There are different parameters to define the strength of soil. In this study, CBR will be used to define the strength of soil. Cement by percentages, 0%, 3%, 7% and 10% added to soil for evaluation effect of added cement to CBR of treated soil. Implementation of stabilization process by different cement content help engineers to select an economic cement amount for the stabilization process according to project specification and characteristics. Stabilization process in optimum moisture content (OMC) and mixing rate effect on the strength of soil in the laboratory and field construction operation have been performed to see the improvement rate in strength and plasticity. Cement stabilization is quicker than a universal method such as removing and changing field soils. Cement addition increases CBR values of different soil types by the range of 22-69%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=California%20Bearing%20Ratio" title="California Bearing Ratio">California Bearing Ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20stabilization" title=" cement stabilization"> cement stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=clayey%20soil" title=" clayey soil"> clayey soil</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/68673/effect-of-cement-amount-on-california-bearing-ratio-values-of-different-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68673.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">397</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">1009</span> Optimizing Cellulase Production from Municipal Solid Wastes (MSW) Following a Solid State Fermentation (SSF) by Trichoderma reesei and Aspergillus niger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jwan%20J.%20Abdullah">Jwan J.

This paper describes the optimisation of SSF on municipal solid waste (MSW) for the production of cellulase enzyme. Production of cellulase enzymes was optimised by Trichoderma reesei or Aspergillus niger for temperature, moisture content, inoculation, and period of incubation. Also, presence of minerals, and alternative carbon and nitrogen sources. Optimisation revealed that production of cellulolytic enzymes was optimal when using Trichoderma spp at 30°C with an incubation period of 168 hours with a 60% moisture content. Crude enzymes produced from MSW, by Trichoderma were evaluated for the saccharification of MSW and compared with activity of a commercially available enzyme, results demonstrated that MSW can be used as inexpensive lignocellulosic material for the production of cellulase enzymes using Trichoderma reesei. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SSF" title="SSF">SSF</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20hydrolysis" title=" enzyme hydrolysis"> enzyme hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=municipal%20solid%20waste%20%28MSW%29" title=" municipal solid waste (MSW)"> municipal solid waste (MSW)</a>, <a href="https://publications.waset.org/abstracts/search?q=optimizing%20conditions" title=" optimizing conditions"> optimizing conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20hydrolysis" title=" enzyme hydrolysis "> enzyme hydrolysis </a> </p> <a href="https://publications.waset.org/abstracts/26580/optimizing-cellulase-production-from-municipal-solid-wastes-msw-following-a-solid-state-fermentation-ssf-by-trichoderma-reesei-and-aspergillus-niger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26580.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">555</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">1008</span> Effect of Nano-SiO2 Solution on the Strength Characteristics of Kaolinite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ziaie%20Moayed">Reza Ziaie Moayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Rahmani"> Hamidreza Rahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, with developments in science and technology, there is an excessive potential for the use of nanomaterials in various fields of geotechnical project such as soil stabilization.

The major problem of these products, mainly the acidic ones, is phase separation which occurs during formulation and storage due to the aggregation of caseins at low pH Short-chain inulin (CLR), long-chain inulin (TEX), native inulin (IQ) and Long-chain inulin (TEX) and short-chain inulin (CLR) combined in different proportions (2o:80, 50:50, and 80:20) were added (2-10 %) to sourcherry juice-milk mixture and their stabilization mechanisms were studied with using rheological and microstructural observations. Stevioside as a bio-sweetener and sugar-replacer was added at last step. Finally, sensory analyses were taken place on stabilized samples. According to the findings, TEX stabilized the mixture at concentration of 8%. MIX and IQ reduced phase separation at high concentration but had not complete effect on stabilization. CLR did not effect on stabilization. Rheological changes and inulin aggregates formation were not observed in CLR samples during the one month storage period. However TEX, MIX and IQ samples formed inulin aggregates and became more thixotropic, elastic and increased the viscosity of mixture. The rate of the inulin aggregates formation and viscosity increasing was in the following order TEX > MIX > IQ. Consequently the mixture which stabilized with inulin and sweetened with stevioside had the prebiotic properties which may suggest to diabetic patients and children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prebiotic" title="prebiotic">prebiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=inulin" title=" inulin"> inulin</a>, <a href="https://publications.waset.org/abstracts/search?q=casein" title=" casein"> casein</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=stevioside" title=" stevioside"> stevioside</a> </p> <a href="https://publications.waset.org/abstracts/9535/the-effects-of-inulin-on-the-stabilization-and-stevioside-as-sugar-replacer-of-sourcherry-juice-milk-mixture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9535.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">274</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">1006</span> Assessment of Diagnostic Enzymes as Indices of Heavy Metal Pollution in Tilapia Fish</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justina%20I.%20R.%20Udotong">Justina I.

Three different sets of fishes treated with lead (Pb), iron (Fe) and copper (Cu) were used for the study while a fourth group with no heavy metal served as a control. Fishes in each of the groups were exposed to 2.65 mg/l of Pb, 0.85 mg/l of Fe and 0.35 mg/l of Cu in aerated aquaria for 96 hours. Tissue fractionation of the liver tissues was carried out and the three diagnostic enzymes (AST, ALT, and ALP) were estimated. Serum levels of the same diagnostic enzymes were also measured. The mean values of the serum enzyme activity for ALP in each experimental group were 19.5±1.62, 29.67±2.17 and 1.15±0.27 IU/L for Pb, Fe and Cu groups compared with 9.99±1.34 IU/L enzyme activity in the control. This result showed that Pb and Fe caused increased release of the enzyme into the blood circulation indicating increased tissue damage while Cu caused a reduction in the serum level as compared with the level in the control group. The mean values of enzyme activity obtained in the liver were 102.14±6.12, 140.17±2.06 and 168.23±3.52 IU/L for Pb, Fe and Cu groups, respectively compared to 91.20±9.42 IU/L enzyme activity for the control group. The serum and liver AST and ALT activities obtained in Pb, Fe, Cu and control groups are reported. It was generally noted that the presence of the heavy metal caused liver tissues damage and consequent increased level of the diagnostic enzymes in the serum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diagnostic%20enzymes" title="diagnostic enzymes">diagnostic enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20activity" title=" enzyme activity"> enzyme activity</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=tissues%20investigations" title=" tissues investigations"> tissues investigations</a> </p> <a href="https://publications.waset.org/abstracts/31272/assessment-of-diagnostic-enzymes-as-indices-of-heavy-metal-pollution-in-tilapia-fish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31272.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">290</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">1005</span> Bioactivity of Peptides from Two Mushrooms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Farzaneh">Parisa Farzaneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Azade%20Harati"> Azade Harati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mushrooms, or macro-fungi, as an important superfood, contain many bioactive compounds, particularly bio-peptides. In this research, mushroom proteins were extracted by buffer or buffer plus salt (0.15 M), along with an ultrasound bath to extract the intercellular protein. As a result, the highest amount of proteins in mushrooms were categorized into albumin. Proteins were also hydrolyzed and changed into peptides through endogenous and exogenous proteases, including gastrointestinal enzymes. The potency of endogenous proteases was also higher in Agaricus bisporus than Terfezia claveryi, as their activity ended at 75 for 15 min. The blanching process, endogenous enzymes, the mixture of gastrointestinal enzymes (pepsin-trypsin-α-chymotrypsin or trypsin- α-chymotrypsin) produced the different antioxidant and antibacterial hydrolysates. The peptide fractions produced with different cut-off ultrafilters also had various levels of radical scavenging, lipid peroxidation inhibition, and antibacterial activities. The bio-peptides with superior bioactivities (less than 3 kD of T. claveryi) were resistant to various environmental conditions (pH and temperatures). Therefore, they are good options to be added to nutraceutical and pharmaceutical preparations or functional foods, even during processing. <p class="card-text"><strong>Keywords:</strong> <a
