Thus, in this study we investigated the mechanisms related to anti-obesity activity in-vitro. The HP was fractionated, and effect on the triglyceride (TG) content was evaluated in 3T3-L1 and HepG2 cells. Comprehensive spectroscopic analyses were used to identify the structure of the active compound. The dose dependent effect of active constituent on the TG content, and the gene expressions related to adipogenesis, fatty acid catabolism, energy expenditure, lipolysis and lipogenesis (20 μg/mL) were examined in-vitro. Furthermore, higher dosage of pteryxin (50μg/mL) was tested against 20μg/mL in 3T3-L1 adipocytes. The mRNA were subjected to SOLiD next generation sequencer and the obtained data were analyzed by Ingenuity Pathway Analysis (IPA). The active constituent was identified as pteryxin, a known compound in PJT. However, its biological activities against obesity have not been reported previously. Pteryxin dose dependently suppressed TG content in both 3T3-L1 adipocytes and HepG2 hepatocytes (P < 0.05). Sterol regulatory element-binding protein-1 (SREBP1 c), Fatty acid synthase (FASN), and acetyl-CoA carboxylase-1 (ACC1) were downregulated in pteryxin-treated adipocytes (by 18.0, 36.1 and 38.2%; P < 0.05, respectively) and hepatocytes (by 72.3, 62.9 and 38.8%, respectively; P < 0.05) indicating its suppressive effects on fatty acid synthesis. The hormone-sensitive lipase (HSL), a lipid catabolising gene was upregulated (by 15.1%; P < 0.05) in pteryxin-treated adipocytes suggesting improved lipolysis. Concordantly, the adipocyte size marker gene, paternally expressed gene1/mesoderm specific transcript (MEST) was downregulated (by 42.8%; P < 0.05), further accelerating the lipolytic activity. The upregulated trend of uncoupling protein 2 (UCP2; by 77.5%; P < 0.05) reflected the improved energy expenditure due to pteryxin. The 50μg/mL dosage of pteryxin completely suppressed PPARγ, MEST, SREBP 1C, HSL, Adiponectin, Fatty Acid Binding Protein (FABP) 4, and UCP’s in 3T3-L1 adipocytes. The IPA suggested that pteryxin at 20μg/mL and 50μg/mL suppress obesity in two different pathways, whereas the WNT signaling pathway play a key role in the higher dose of pteryxin in preadipocyte stage. Pteryxin in PJT play the key role in regulating lipid metabolism related gene network and improving energy production in vitro. Thus, the results suggests pteryxin as a new natural compound to be used as an anti-obesity drug in pharmaceutical industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obesity" title="obesity">obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=peucedanum%20japonicum%20thunb" title=" peucedanum japonicum thunb"> peucedanum japonicum thunb</a>, <a href="https://publications.waset.org/abstracts/search?q=pteryxin" title=" pteryxin"> pteryxin</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20science" title=" food science"> food science</a> </p> <a href="https://publications.waset.org/abstracts/26176/anti-obesity-effects-of-pteryxin-in-peucedanum-japonicum-thunb-leaves-through-different-pathways-of-adipogenesis-in-vitro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26176.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">453</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">8</span> Endothelin Cells and Its Molecular Biology and Microbiology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chro%20Kawyan">Chro Kawyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Endothelin-1 (ET-1), the principal individual from the newfound mammalian endothelin group of organically dynamic peptides, was initially distinguished as a 21 buildup powerful vasoconstrictor peptide in vascular endothelial cells. However, it has since been demonstrated to have a wide range of pharmacological activities in tissues both inside and outside the cardiovascular system. Additionally, peptides that have a striking resemblance to ET-1 have been identified as the primary toxic component of snake venom. In addition, late examinations have proposed that warm blooded creatures, including people, produce three unmistakable individuals from this peptide family, ET-1, ET-2 and ET-J, which might have various profiles of organic action and may follow up on particular subtypes of endothelin receptor. Masashi Yanagisawa and Tomoh Masaki survey the ongoing status of the organic chemistry and sub-atomic science of endothelin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thelin" title="thelin">thelin</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiology" title=" microbiology"> microbiology</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20biology" title=" molecular biology"> molecular biology</a>, <a href="https://publications.waset.org/abstracts/search?q=cell" title=" cell"> cell</a> </p> <a href="https://publications.waset.org/abstracts/172519/endothelin-cells-and-its-molecular-biology-and-microbiology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Development Process and Design Methods for Shared Spaces in Europe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazuyasu%20Yoshino">Kazuyasu Yoshino</a>, <a href="https://publications.waset.org/abstracts/search?q=Keita%20Yamaguchi"> Keita Yamaguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshihiko%20Nishimura"> Toshihiko Nishimura</a>, <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Kawasaki"> Masashi Kawasaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shared Space, the planning and design concept that allows pedestrians and vehicles to coexist in a street space, has been advocated and developed according to the traffic conditions in each country in Europe. Especially in German/French-speaking countries, the "Meeting Zone," which is a traffic rule combining speed regulation (20km/h) and pedestrian priority, is often applied when designing shared spaces at intersections, squares, and streets in the city center. In this study, the process of establishment and development of the Meeting Zone in Switzerland, France, and Austria was chronologically organized based on the descriptions in the major discourse and guidelines in each country. Then, the characteristics of the spatial design were extracted by analyzing representative examples of Meeting Zone applications.

A non-isothermal forming for CFRTP can shorten its cycle time to less than 1 minute. In this paper, the textile reinforcement FE model which the authors proposed in a previous work is extended to the CFRTP model for non-isothermal forming simulation. The effect of thermoplastic is given by adding shell elements which consider thermal effect to the textile reinforcement model. By applying Reuss model to the stress calculation of thermoplastic, the proposed model can accurately predict in-plane shear behavior, which is the key deformation mode during forming, in the range of the process temperature. Using the proposed model, thermoforming simulation was conducted and the results are in good agreement with the experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20fiber%20reinforced%20thermoplastic" title="carbon fiber reinforced thermoplastic">carbon fiber reinforced thermoplastic</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-impregnated%20textile%20composite" title=" pre-impregnated textile composite"> pre-impregnated textile composite</a>, <a href="https://publications.waset.org/abstracts/search?q=non-isothermal%20forming" title=" non-isothermal forming"> non-isothermal forming</a> </p> <a href="https://publications.waset.org/abstracts/12983/forming-simulation-of-thermoplastic-pre-impregnated-textile-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12983.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">429</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">5</span> CT-Scan Transition of Pulmonary Edema Due to Water-Soluble Paint Inhalation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Kanazawa">Masashi Kanazawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Takaaki%20Nakano"> Takaaki Nakano</a>, <a href="https://publications.waset.org/abstracts/search?q=Masaaki%20Takemoto"> Masaaki Takemoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomonori%20Imamura"> Tomonori Imamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamiko%20Sugimura"> Mamiko Sugimura</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshitaka%20Ito"> Toshitaka Ito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: We experienced a massive disaster due to inhalation of water-soluble paint. Sixteen patients were brought to our emergency room, and pulmonary edema was revealed on the CT images of 12 cases. Purpose: Transition of chest CT-scan findings in cases with pulmonary edema was examined. Method: CT-scans were performed on the 1st, 2nd, 5th, and 19th days after the inhalation event. Patients whose pulmonary edema showed amelioration or exacerbation were classified into the improvement or the exacerbation group, respectively. Those with lung edema findings appearing at different sites after the second day were classified into the changing group. Results: Eight, one and three patients were in the improvement, exacerbation and changing groups, respectively. In all cases, the pulmonary edema had disappeared from CT images on the 19th day after the inhalation event. Conclusion: Inhalation of water-soluble paints is considered to be relatively safe. However, our observations in these emergency cases suggest that, even if pulmonary edema is not severe immediately after the exposure, new lesions may appear later and existing lesions may worsen. Follow-up imaging is thus necessary for about two weeks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CT%20scan" title="CT scan">CT scan</a>, <a href="https://publications.waset.org/abstracts/search?q=intoxication" title=" intoxication"> intoxication</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20edema" title=" pulmonary edema"> pulmonary edema</a>, <a href="https://publications.waset.org/abstracts/search?q=water-soluble%20paint" title=" water-soluble paint"> water-soluble paint</a> </p> <a href="https://publications.waset.org/abstracts/74622/ct-scan-transition-of-pulmonary-edema-due-to-water-soluble-paint-inhalation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74622.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">173</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">4</span> Isolation, Identification and Characterization of the Bacteria and Yeast from the Fermented Stevia Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asato%20Takaishi">Asato Takaishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Nasuhara"> Masashi Nasuhara</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayuko%20Itsuki"> Ayuko Itsuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenichi%20Suga"> Kenichi Suga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stevia (Stevia rebaudiana Bertoni) is a composite plant native to Paraguay. Stevia sweetener is derived from a hot water extract of Stevia (Stevia extract), which has some effects such as histamine decomposition, antioxidative effect, and blood sugar level-lowering function. The steviol glycosides in the Stevia extract are considered to contribute to these effects. In addition, these effects increase by the fermentation. However, it takes a long time for fermentation of Stevia extract and the fermentation liquid sometimes decays during the fermentation process because natural fermentation method is used. The aim of this study is to perform the fermentation of Stevia extract in a shorter period, and to produce the fermentation liquid in stable quality. From the natural fermentation liquid of Stevia extract, the four strains of useful (good taste) microorganisms were isolated using dilution plate count method and some properties were determined. The base sequences of 16S rDNA and 28S rDNA revealed three bacteria (two Lactobacillus sp. and Microbacterium sp.) and one yeast (Issatchenkia sp.). This result has corresponded that several kinds of lactic bacterium such as Lactobacillus pentosus and Lactobacillus buchneri were isolated from Stevia leaves. Liquid chromatography/mass spectrometory (LC/MS/MS) and High-Performance Liquid Chromatography (HPLC) were used to determine the contents of steviol glycosides and neutral sugars. When these strains were cultured in the sterile Stevia extract, the steviol and stevioside were increased in the fermented Stevia extract. So, it was suggested that the rebaudioside A and the mixture of steviol glycosides in the Stevia extract were decomposed into stevioside and steviol by microbial metabolism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fermentation" title="fermentation">fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=lactobacillus" title=" lactobacillus"> lactobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=Stevia" title=" Stevia"> Stevia</a>, <a href="https://publications.waset.org/abstracts/search?q=steviol%20glycosides" title=" steviol glycosides"> steviol glycosides</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a> </p> <a href="https://publications.waset.org/abstracts/62007/isolation-identification-and-characterization-of-the-bacteria-and-yeast-from-the-fermented-stevia-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62007.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">564</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">3</span> A Linear Regression Model for Estimating Anxiety Index Using Wide Area Frontal Lobe Brain Blood Volume</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Kaburagi">Takashi Kaburagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Takenaka"> Masashi Takenaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosuke%20Kurihara"> Yosuke Kurihara</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Matsumoto"> Takashi Matsumoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Major depressive disorder (MDD) is one of the most common mental illnesses today. It is believed to be caused by a combination of several factors, including stress. Stress can be quantitatively evaluated using the State-Trait Anxiety Inventory (STAI), one of the best indices to evaluate anxiety. Although STAI scores are widely used in applications ranging from clinical diagnosis to basic research, the scores are calculated based on a self-reported questionnaire. An objective evaluation is required because the subject may intentionally change his/her answers if multiple tests are carried out. In this article, we present a modified index called the “multi-channel Laterality Index at Rest (mc-LIR)” by recording the brain activity from a wider area of the frontal lobe using multi-channel functional near-infrared spectroscopy (fNIRS). The presented index aims to measure multiple positions near the F<sub>pz</sub> defined by the international 10-20 system positioning. Using 24 subjects, the dependencies on the number of measuring points used to calculate the mc-LIR and its correlation coefficients with the STAI scores are reported. Furthermore, a simple linear regression was performed to estimate the STAI scores from mc-LIR. The cross-validation error is also reported. The experimental results show that using multiple positions near the Fpz will improve the correlation coefficients and estimation than those using only two positions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frontal%20lobe" title="frontal lobe">frontal lobe</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20near-infrared%20spectroscopy" title=" functional near-infrared spectroscopy"> functional near-infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=state-trait%20anxiety%20inventory%20score" title=" state-trait anxiety inventory score"> state-trait anxiety inventory score</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/67667/a-linear-regression-model-for-estimating-anxiety-index-using-wide-area-frontal-lobe-brain-blood-volume" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67667.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">250</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">2</span> Cytogenetic Characterization of the VERO Cell Line Based on Comparisons with the Subline; Implication for Authorization and Quality Control of Animal Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fumio%20Kasai">Fumio Kasai</a>, <a href="https://publications.waset.org/abstracts/search?q=Noriko%20Hirayama"> Noriko Hirayama</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Pereira"> Jorge Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Azusa%20Ohtani"> Azusa Ohtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Iemura"> Masashi Iemura</a>, <a href="https://publications.waset.org/abstracts/search?q=Malcolm%20A.%20Ferguson%20Smith"> Malcolm A.

The VERO genome was sequenced in 2014; however, its cytogenetic features have not been fully characterized as it contains several chromosome abnormalities and different karyotypes coexist in the cell line. In this study, the VERO cell line (JCRB0111) was compared with one of the sublines. In contrast to 59 chromosomes as the modal chromosome number in the VERO cell line, the subline had two peaks of 56 and 58 chromosomes. M-FISH analysis using human probes revealed that the VERO cell line was characterized by a translocation t(2;25) found in all metaphases, which was absent in the subline. Different abnormalities detected only in the subline show that the cell line is heterogeneous, indicating that the subline has the potential to change its genomic characteristics during cell culture. The various alterations in the two independent lineages suggest that genomic changes in both VERO cells can be accounted for by progressive rearrangements during their evolution in culture. Both t(5;X) and t(8;14) observed in all metaphases of the two cell lines might have a key role in VERO cells and could be used as genetic markers to identify VERO cells. The flow karyotype shows distinct differences from normal. Further analysis of sorted abnormal chromosomes may uncover other characteristics of VERO cells. Because of the absence of STR data, cytogenetic data are important in characterizing animal cell lines and can be an indicator of their quality control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VERO" title="VERO">VERO</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20culture%20passage" title=" cell culture passage"> cell culture passage</a>, <a href="https://publications.waset.org/abstracts/search?q=chromosome%20rearrangement" title=" chromosome rearrangement"> chromosome rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20cells" title=" heterogeneous cells"> heterogeneous cells</a> </p> <a href="https://publications.waset.org/abstracts/32913/cytogenetic-characterization-of-the-vero-cell-line-based-on-comparisons-with-the-subline-implication-for-authorization-and-quality-control-of-animal-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32913.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">416</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">1</span> Focus on the Bactericidal Efficacies of Alkaline Agents in Solid and the Required Time for Bacterial Inactivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hakimullah%20Hakim">Hakimullah Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiharu%20Toyofuku"> Chiharu Toyofuku</a>, <a href="https://publications.waset.org/abstracts/search?q=Mari%20Ota"> Mari Ota</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayuko%20Suzuki"> Mayuko Suzuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Miyuki%20Komura"> Miyuki Komura</a>, <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Yamada"> Masashi Yamada</a>, <a href="https://publications.waset.org/abstracts/search?q=Md.%20Shahin%20Alam"> Md.

Alkaline agents are well known for their strong and long term antimicrobial capacities and most frequently are applied at farms for control and prevention of biological hazards. However, inadequate information regarding such materials’ capacities to inactivate pathogens and their improper applications fail farmers to achieve the mentioned goal. Thus, this requires attention to further evaluate their efficacies, under different conditions and in different ways. Here in this study we evaluated bactericidal efficacies of food additive grade of calcium hydroxide (FdCa(OH)2) powder derived from natural calcium carbonates obtained from limestone (Fine Co., Ltd., Tokyo, Japan), and bioceramic powder (BCX) derived from chicken feces at pH 13 (NMG environmental development Co., Ltd., Tokyo, Japan), for their efficacies to inactivate bacteria in feces. [Materials & Methods] Chicken feces were inoculated by 100 µl Escherichia coli and Salmonella Infantis in falcon tubes, individually, then FdCa(OH)2 or BCX powders were individually added to make final concentration of 0, 5, 10, 20 and 30% (w/w) in total weight of 0.5g, followed by properly mixing and incubating at room temperature for certain periods of time, in a dark place. Afterwards, 10 ml 1M Tris-HCl (pH 7.2) was added onto them to reduce their pH, in order to stop powders’ activities and to harvest the remained viable bacteria, whereas using normal medium or dW2 to recover bacteria increases the mixture pH, and as a result bacteria would be inactivated soon; therefore, the latter practice brings about incorrect and misleading results. Samples were then inoculated on DHL agar plates in order to calculate colony forming units (CFU)/ml of viable bacteria. [Results and Discussion] FdCa(OH)2 powder at 10% and 5% required 3 hr and 6 hr exposure times, respectively, while BCX powder at 20% concentrations required 6 hr exposure time to kill the mentioned bacteria in feces down to lower than detectable level (≤ 3.6 log10 CFU/ml). This study confirmed capacities of FdCa(OH)2 and BCX powders to inactivate bacteria in feces, and both materials are environment friendly materials, with no risk to human or animal’s health. This finding helps farmers to properly apply alkaline agents in appropriate concentrations and exposure times in their farms, in order to prevent and control infectious diseases outbreaks and to enhance biosecurity. Finally, this finding may help farmers to implement better strategies for infections control in their livestock farms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20inactivation" title="bacterial inactivation">bacterial inactivation</a>, <a href="https://publications.waset.org/abstracts/search?q=bioceramic" title=" bioceramic"> bioceramic</a>, <a href="https://publications.waset.org/abstracts/search?q=biosecurity%20at%20livestock%20farms" title=" biosecurity at livestock farms"> biosecurity at livestock farms</a>, <a href="https://publications.waset.org/abstracts/search?q=chicken%20feces" title=" chicken feces"> chicken feces</a> </p> <a href="https://publications.waset.org/abstracts/49905/focus-on-the-bactericidal-efficacies-of-alkaline-agents-in-solid-and-the-required-time-for-bacterial-inactivation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49905.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">440</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
