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.

Shukla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Degradation of biological samples in terms of macromolecules (DNA, RNA, and protein) are the major challenges in the forensic investigation which misleads the result interpretation. Currently, there are no precise methods available to circumvent this problem. Therefore, at the preliminary level, some methods are urgently needed to solve this issue. In this order, Comet assay is one of the most versatile, rapid and sensitive molecular biology technique to assess the DNA degradation. This technique helps to assess DNA degradation even at very low amount of sample. Moreover, the expedient part of this method does not require any additional process of DNA extraction and isolation during DNA degradation assessment. Samples directly embedded on agarose pre-coated microscopic slide and electrophoresis perform on the same slide after lysis step. After electrophoresis microscopic slide stained by DNA binding dye and observed under fluorescent microscope equipped with Komet software. With the help of this technique extent of DNA degradation can be assessed which can help to screen the sample before DNA fingerprinting, whether it is appropriate for DNA analysis or not. This technique not only helps to assess degradation of DNA but many other challenges in forensic investigation such as time since deposition estimation of biological fluids, repair of genetic material from degraded biological sample and early time since death estimation could also be resolved. With the help of this study, an attempt was made to explore the application of well-known molecular biology technique that is Comet assay in the field of forensic science. This assay will open avenue in the field of forensic research and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comet%20assay" title="comet assay">comet assay</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20degradation" title=" DNA degradation"> DNA degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic" title=" forensic"> forensic</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20biology" title=" molecular biology"> molecular biology</a> </p> <a href="https://publications.waset.org/abstracts/88073/assessment-of-dna-degradation-using-comet-assay-a-versatile-technique-for-forensic-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88073.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">155</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">2428</span> Implementation of an Undergraduate Integrated Biology and Chemistry Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayson%20G.%20Balansag">Jayson G.

This course will prepare students to (1) become interdisciplinary thinkers in the field of biology and (2) collaboratively work with others from multiple disciplines in the future. This paper documents and describes the implementation of the course. The information gathered from reading literature, classroom observations, and interviews were used to carry out the purpose of this paper. The major goal of the iBC course is to align the concepts between Biology and Chemistry, so that students can draw science concepts from both disciplines which they can apply in their interdisciplinary researches. This course is offered every fall and spring semesters of each school year. Students enrolled in Biology are also enrolled in Chemistry during the same semester. The iBC is composed of lectures, laboratories, studio sessions, and workshops and is taught by the faculty from the biology and chemistry departments. In addition, the preceptors, graduate teaching assistants, and studio fellows facilitate the laboratory and studio sessions. These roles are interdependent with each other. The iBC can be used as a model for higher education institutions who wish to implement an integrated biology course. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20biology%20and%20chemistry" title="integrated biology and chemistry">integrated biology and chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=interdisciplinary%20research" title=" interdisciplinary research"> interdisciplinary research</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20biology" title=" new biology"> new biology</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20science%20education" title=" undergraduate science education"> undergraduate science education</a> </p> <a href="https://publications.waset.org/abstracts/76611/implementation-of-an-undergraduate-integrated-biology-and-chemistry-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76611.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">245</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">2427</span> Characterization of Some Bread Wheat Genotypes for Drought Tolerance Using Molecular Markers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beg%C3%BCm%20Terzi">Begüm Terzi</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zlem%20Ate%C5%9F%20S%C3%B6nmezo%C4%9Flu"> Özlem Ateş Sönmezoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Yildirim"> Ahmet Yildirim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drought is the most important factor that limiting the production and productivity of wheat in the world. The yield of wheat, which is one of the most important crop in the world, reduced depend on drought. Researches to minimize effects of drought are one of the most important about breeding of drought resistant varieties. In recent years, benefiting from the drought resistance wild species and rapid advances in molecular biology studies, researches about drought have been accelerated and number of studies were made on molecular plant breeding which included the molecular mechanisms related to drought resistance. The aim of the present study was characterization of some bread wheat lines for drought tolerance which commonly cultivated in different location of Turkey. In this study, registered 9 bread wheat varieties which on the physiological tests about drought tolerance and 10 bread wheat line has been developed by Transitional Zone Agricultural Research Institute were used. SSR, STS, RAPD and SNP markers that associated with drought tolerance were used. The polymorphisms of the markers were determined by screening of two control varieties. For these purpose 40 molecular markers were used and 12 markers of them were polymorphic among the drought tolerance and the drought sensitive varieties. Control varieties were screened using polymorphic markers. All the DNAs on the genotypes will be searched for the presence of QTLs mapped to different chromosomes. Result of the research, the studied genotypes will be grouped according to drought tolerance and will be detected drought tolerance varieties by molecular markers. In addition, the results will be compared also with physiological tests. The drought tolerant wheat genotypes may be used in breeding studies related to drought stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bread%20wheat" title="bread wheat">bread wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20marker" title=" molecular marker"> molecular marker</a>, <a href="https://publications.waset.org/abstracts/search?q=Triticum%20aestivum" title=" Triticum aestivum"> Triticum aestivum</a> </p> <a href="https://publications.waset.org/abstracts/49403/characterization-of-some-bread-wheat-genotypes-for-drought-tolerance-using-molecular-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49403.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">385</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">2426</span> Exploring and Evaluating the Current Style of Teaching Biology in Saudi Universities from Teachers' Points of View</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibraheem%20Alzahrani">Ibraheem Alzahrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Saudi Arabia ministry of higher education has established 24 universities across various cities in the kingdom.

This center has built a teaching and learning biology curriculum that suits the ability of these gifted students. The level of PERMATApintar<sup>®</sup> biology curriculum is basically higher than the national biology curriculum. Here, the foundation students are exposed to the PERMATApintar<sup>®</sup> biology curriculum at the age of as early as 11 years old. This center practices a 4-time-a-year examination system to monitor the academic performances of the students. Generally, most of the time, male students show no or low interest towards biology subject compared to female students. This study is to investigate the association of students’ gender and their academic performances in biology examination. A total of 39 students’ scores in twelve sets of biology examinations in 3 years have been collected and analyzed by using the statistical analysis. Based on the analysis, there are no significant differences between male and female students against the biology academic performances with a significant level of p = 0.05. This indicates that gender is not associated with the scores of biology examinations among the students. Another result showed that the average score for male studenta was higher than the female students. Future research can be done by comparing the biology academic achievement in Malaysian National Examination (Sijil Pelajaran Malaysia, SPM) between the Foundation 3 students (Grade 9) and Level 2 students (Grade 11) with similar PERMATApintar<sup>®</sup> biology curriculum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20performances" title="academic performances">academic performances</a>, <a href="https://publications.waset.org/abstracts/search?q=biology" title=" biology"> biology</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20differences" title=" gender differences"> gender differences</a>, <a href="https://publications.waset.org/abstracts/search?q=gifted%20students" title=" gifted students"> gifted students</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/89501/gender-differences-in-biology-academic-performances-among-foundation-students-of-permatapintar-national-gifted-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89501.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">243</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">2424</span> Thick Disc Molecular Gas Fraction in NGC 6946</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narendra%20Nath%20Patra">Narendra Nath Patra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several recent studies reinforce the existence of a thick molecular disc in galaxies along with the dynamically cold thin disc. Assuming a two-component molecular disc, we model the disc of NGC 6946 as a four-component system consists of stars, HI, thin disc molecular gas, and thick disc molecular gas in vertical hydrostatic equilibrium. Following, we set up the joint Poisson-Boltzmann equation of hydrostatic equilibrium and solve it numerically to obtain a three-dimensional density distribution of different baryonic components. Using the density solutions and the observed rotation curve, we further build a three-dimensional dynamical model of the molecular disc and consecutively produce simulated CO spectral cube and spectral width profile. We find that the simulated spectral width profiles distinguishably differs for different assumed thick disc molecular gas fraction. Several CO spectral width profiles are then produced for different assumed thick disc molecular gas fractions and compared with the observed one to obtain the best fit thick disc molecular gas fraction profile. We find that the thick disc molecular gas fraction in NGC 6946 largely remains constant across its molecular disc with a mean value of 0.70 +/- 0.09. We also estimate the amount of extra-planar molecular gas in NGC 6946. We find 60% of the total molecular gas is extra-planar at the central region, whereas this fraction reduces to ~ 35% at the edge of the molecular disc. With our method, for the first time, we estimate the thick disc molecular gas fraction as a function of radius in an external galaxy with sub-kpc resolution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=galaxies%3A%20kinematics%20and%20dynamic" title="galaxies: kinematics and dynamic">galaxies: kinematics and dynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=galaxies%3A%20spiral" title=" galaxies: spiral"> galaxies: spiral</a>, <a href="https://publications.waset.org/abstracts/search?q=galaxies%3A%20structure" title=" galaxies: structure "> galaxies: structure </a>, <a href="https://publications.waset.org/abstracts/search?q=ISM%3A%20molecules" title=" ISM: molecules"> ISM: molecules</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20data" title=" molecular data"> molecular data</a> </p> <a href="https://publications.waset.org/abstracts/123278/thick-disc-molecular-gas-fraction-in-ngc-6946" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123278.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">144</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">2423</span> Molecular Clustering and Velocity Increase in Converging-Diverging Nozzle in Molecular Dynamics Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeoungsu%20Na">Jeoungsu Na</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaehawn%20Lee"> Jaehawn Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Changil%20Hong"> Changil Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Suhee%20Kim"> Suhee Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A molecular dynamics simulation in a converging-diverging nozzle was performed to study molecular collisions and their influence to average flow velocity according to a variety of vacuum levels.

The result shows that the velocities increased at the nozzle exit as the vacuum level gets higher in that area because less molecular collisions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavitation" title="cavitation">cavitation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20collision" title=" molecular collision"> molecular collision</a>, <a href="https://publications.waset.org/abstracts/search?q=nozzle" title=" nozzle"> nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum" title=" vacuum"> vacuum</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20increase" title=" velocity increase"> velocity increase</a> </p> <a href="https://publications.waset.org/abstracts/61069/molecular-clustering-and-velocity-increase-in-converging-diverging-nozzle-in-molecular-dynamics-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61069.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">431</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">2422</span> Environmental Variables as Determinants of Students Achievement in Biology Secondary Schools in South West Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayeni%20Margaret%20Foluso">Ayeni Margaret Foluso</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20A.%20Omotayo"> K.

Breast cancer shows a unique spread pattern, often affecting bone, liver, lung, and brain. Breast cancer can be categorized into various subtypes according to gene expression patterns, and these subtypes exhibit specific preferences for organs where metastasis occurs. Breast tumors with luminal characteristics have a preference for spreading to the bone, whereas basal-like breast cancer (BLBC) shows a tendency to metastasize to the lungs. Still, the mechanisms behind this particular pattern of metastasis in organs have yet to be fully understood. In this evaluation, we will outline the latest progress in molecular signaling pathways and treatment methods for breast cancer lung metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title="lung cancer">lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer" title=" liver cancer"> liver cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=BLBC" title=" BLBC"> BLBC</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a> </p> <a href="https://publications.waset.org/abstracts/185132/metastasis-of-breast-cancer-to-the-lungs-implications-of-molecular-biology-and-treatment-options" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185132.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">48</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">2420</span> Molecular Junctions between Graphene Strips: Electronic and Transport Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adel%20Belayadi">Adel Belayadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mougari"> Ahmed Mougari</a>, <a href="https://publications.waset.org/abstracts/search?q=Boualem%20Bourahla"> Boualem Bourahla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Molecular junctions are currently considered a promising style in the miniaturization of electronic devices.

In Malaysia, this scenario also draws the attention of Ministry of Education due to the high demand for professionals in STEM industries and for the sake of country development. Intensive researches have been done worldwide to identify the best solution to improve the enrolment of students in science studies. Attitude is being identified as one of the key factors that will influence students’ interest and achievement in academic. Male students are always associated with negative attitudes compared to female students towards the study of Biological science. Hence, this study investigates the attitudes of students towards Biology in the setting of an academic talented institution in Malaysia namely ASASIpintar Pre-University Programme. A total of 84 students were randomly selected from 127 students as the samples of this study. The instrument of Biology Attitude Scale (BAS) from Russell and Hollander (1975) was used to identify the attitudes of samples. Based on the analysis, there was no significant difference in the students’ mean attitude towards Biology subject in this institution between genders with a significant level of p = 0.05. This indicated that gender is not a key factor that influences students’ attitude towards Biology in this study. Future research can be done on other factors that will contribute to the attitude of students towards biology in Malaysia, especially for academically talented students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20talented" title="academic talented">academic talented</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=biology" title=" biology"> biology</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a> </p> <a href="https://publications.waset.org/abstracts/89390/attitude-towards-biology-among-academic-talented-students-in-term-of-gender-case-study-of-asasipintar-pre-university-programme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89390.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">226</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">2418</span> Bioinformatics High Performance Computation and Big Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javed%20Mohammed">Javed Mohammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Right now, bio-medical infrastructure lags well behind the curve. Our healthcare system is dispersed and disjointed; medical records are a bit of a mess; and we do not yet have the capacity to store and process the crazy amounts of data coming our way from widespread whole-genome sequencing. And then there are privacy issues. Despite these infrastructure challenges, some researchers are plunging into bio medical Big Data now, in hopes of extracting new and actionable knowledge. They are doing delving into molecular-level data to discover bio markers that help classify patients based on their response to existing treatments; and pushing their results out to physicians in novel and creative ways. Computer scientists and bio medical researchers are able to transform data into models and simulations that will enable scientists for the first time to gain a profound under-standing of the deepest biological functions. Solving biological problems may require High-Performance Computing HPC due either to the massive parallel computation required to solve a particular problem or to algorithmic complexity that may range from difficult to intractable. Many problems involve seemingly well-behaved polynomial time algorithms (such as all-to-all comparisons) but have massive computational requirements due to the large data sets that must be analyzed. High-throughput techniques for DNA sequencing and analysis of gene expression have led to exponential growth in the amount of publicly available genomic data. With the increased availability of genomic data traditional database approaches are no longer sufficient for rapidly performing life science queries involving the fusion of data types. Computing systems are now so powerful it is possible for researchers to consider modeling the folding of a protein or even the simulation of an entire human body. This research paper emphasizes the computational biology's growing need for high-performance computing and Big Data. It illustrates this article’s indispensability in meeting the scientific and engineering challenges of the twenty-first century, and how Protein Folding (the structure and function of proteins) and Phylogeny Reconstruction (evolutionary history of a group of genes) can use HPC that provides sufficient capability for evaluating or solving more limited but meaningful instances. This article also indicates solutions to optimization problems, and benefits Big Data and Computational Biology. The article illustrates the Current State-of-the-Art and Future-Generation Biology of HPC Computing with Big Data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20performance" title="high performance">high performance</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20computation" title=" parallel computation"> parallel computation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20data" title=" molecular data"> molecular data</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20biology" title=" computational biology"> computational biology</a> </p> <a href="https://publications.waset.org/abstracts/20931/bioinformatics-high-performance-computation-and-big-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20931.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2417</span> Molecular Docking Assessment of Pesticides Binding to Bacterial Chitinases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diana%20Larisa%20Vladoiu">Diana Larisa Vladoiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasile%20Ostafe"> Vasile Ostafe</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Isvoran"> Adriana Isvoran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Molecular docking calculations reveal that pesticides provide favorable interactions with the bacterial chitinases.

In this paper, molecular dynamics (MD) modeling is employed to predict the effect of plasticizer additive on the mechanical properties of key hydrated cement constituent calcium-silicate-hydrate (CSH) at the molecular, nanometer scale level. Due to complexity, still unknown molecular configuration of CSH, a representative configuration widely accepted in the field of mineral Jennite is employed.

The study design was quasi-experimental, which adopted the pre-test, post-test experimental, and control group design. The experimental group was exposed to practical activities, while the control group was taught with the lecture method. A validated instrument, a biology performance test (BPT) with a reliability coefficient of 0.82, was used to gather data which were analyzed using a t-test and paired sample t-test. Two research questions and hypotheses guided the study. The hypotheses were tested at p≤0.05 level of significance. Findings revealed that: there was a significant difference in the academic performance of students exposed to practical activities compared to their counterparts; there was no significant difference in performance between male and female Biology students exposed to practical activities. The recommendation given was that practical activities should be encouraged in the teaching and learning of Biology for better understanding. The Federal and State Ministry of Education should sponsor biology teachers for training and retraining of teachers to improve the academic performance of students in the subject. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biology" title="biology">biology</a>, <a href="https://publications.waset.org/abstracts/search?q=practical" title=" practical"> practical</a>, <a href="https://publications.waset.org/abstracts/search?q=activity" title=" activity"> activity</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/166945/effects-of-practical-activities-on-performance-among-biology-students-in-zaria-education-zone-kaduna-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166945.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">2413</span> Application of Molecular Markers for Crop Improvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monisha%20Isaac">Monisha Isaac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Use of molecular markers for selecting plants with desired traits has been started long back.

It has become obvious that epigenetic alterations represent a further important layer of (de-)regulation of gene activity. For example, aberrant DNA methylation is a hallmark of many cancer types, and methylation patterns were successfully used to subtype cancer heterogeneity. Hence, unraveling the interplay between different omics levels such as genome, transcriptome and epigenome is inevitable for a mechanistic understanding of molecular deregulation causing complex diseases such as cancer. This objective requires powerful downstream integrative bioinformatics methods as an essential prerequisite to discover the whole genome mutational, transcriptome and epigenome landscapes of cancer specimen and to discover cancer genesis, progression and heterogeneity. Basic challenges and tasks arise ‘beyond sequencing’ because of the big size of the data, their complexity, the need to search for hidden structures in the data, for knowledge mining to discover biological function and also systems biology conceptual models to deduce developmental interrelations between different cancer states. These tasks are tightly related to cancer biology as an (epi-)genetic disease giving rise to aberrant genomic regulation under micro-environmental control and clonal evolution which leads to heterogeneous cellular states. Machine learning algorithms such as self organizing maps (SOM) represent one interesting option to tackle these bioinformatics tasks. The SOMmethod enables recognizing complex patterns in large-scale data generated by highthroughput omics technologies. It portrays molecular phenotypes by generating individualized, easy to interpret images of the data landscape in combination with comprehensive analysis options. Our image-based, reductionist machine learning methods provide one interesting perspective how to deal with massive data in the discovery of complex diseases, gliomas, melanomas and colon cancer on molecular level. As an important new challenge, we address the combined portrayal of different omics data such as genome-wide genomic, transcriptomic and methylomic ones. The integrative-omics portrayal approach is based on the joint training of the data and it provides separate personalized data portraits for each patient and data type which can be analyzed by visual inspection as one option. The new method enables an integrative genome-wide view on the omics data types and the underlying regulatory modes. It is applied to high and low-grade gliomas and to melanomas where it disentangles transversal and longitudinal molecular heterogeneity in terms of distinct molecular subtypes and progression paths with prognostic impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrative%20bioinformatics" title="integrative bioinformatics">integrative bioinformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20mechanisms%20of%20cancer" title=" molecular mechanisms of cancer"> molecular mechanisms of cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=gliomas%20and%20melanomas" title=" gliomas and melanomas"> gliomas and melanomas</a> </p> <a href="https://publications.waset.org/abstracts/79700/integrative-omics-portrayal-disentangles-molecular-heterogeneity-and-progression-mechanisms-of-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79700.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">148</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">2411</span> Topological Analysis of Hydrogen Bonds in Pyruvic Acid-Water Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferid%20Hammami">Ferid Hammami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The molecular geometries of the possible conformations of pyruvic acid-water complexes (PA-(H₂O)ₙ = 1- 4) have been fully optimized at DFT/B3LYP/6-311G ++ (d, p) levels of calculation.

Apposite topological and geometrical parameters are considered as primary indicators of H-bond strength. Atoms in molecules (AIM) analysis shows that pyruvic acid can form a ring structure with water, and the molecular structures are stabilized by both strong O-H...O and C-H...O hydrogen bonds. In large clusters, classical O-H...O hydrogen bonds still exist between water molecules, and a cage-like structure is built around some parts of the central molecule of pyruvic acid. The electrostatic potential energy map (MEP) and the HOMO-LUMO molecular orbital (highest occupied molecular orbital-lowest unoccupied molecular orbital) analysis has been performed for all considered complexes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pyruvic%20acid" title="pyruvic acid">pyruvic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=PA-water%20complex" title=" PA-water complex"> PA-water complex</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20bonding" title=" hydrogen bonding"> hydrogen bonding</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT" title=" DFT"> DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=AIM" title=" AIM"> AIM</a>, <a href="https://publications.waset.org/abstracts/search?q=MEP" title=" MEP"> MEP</a>, <a href="https://publications.waset.org/abstracts/search?q=HOMO-LUMO" title=" HOMO-LUMO"> HOMO-LUMO</a> </p> <a href="https://publications.waset.org/abstracts/139309/topological-analysis-of-hydrogen-bonds-in-pyruvic-acid-water-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139309.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">214</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">2410</span> Characterization on Molecular Weight of Polyamic Acids Using GPC Coupled with Multiple Detectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mei%20Hong">Mei Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Liu"> Wei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuemin%20Dai"> Xuemin Dai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yanxiong%20Pan"> Yanxiong Pan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiangling%20Ji">Xiangling Ji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polyamic acid (PAA) is the precursor of polyimide (PI) prepared by a two-step method, its molecular weight and molecular weight distribution not only play an important role during the preparation and processing, but also influence the final performance of PI. However, precise characterization on molecular weight of PAA is still a challenge because of the existence of very complicated interactions in the solution system, including the electrostatic interaction, hydrogen bond interaction, dipole-dipole interaction, etc. Thus, it is necessary to establisha suitable strategy which can completely suppress these complex effects and get reasonable data on molecular weight. Herein, the gel permeation chromatography (GPC) coupled with differential refractive index (RI) and multi-angle laser light scattering (MALLS) detectors were applied to measure the molecular weight of (6FDA-DMB) PAA using different mobile phases, LiBr/DMF, LiBr/H3PO4/THF/DMF, LiBr/HAc/THF/DMF, and LiBr/HAc/DMF, respectively. It was found that combination of LiBr with HAc can shield the above-mentioned complex interactions and is more conducive to the separation of PAA than only addition of LiBr in DMF. LiBr/HAc/DMF was employed for the first time as a mild mobile phase to effectively separate PAA and determine its molecular weight. After a series of conditional experiments, 0.02M LiBr/0.2M HAc/DMF was fixed as an optimized mobile phase to measure the relative and absolute molecular weights of (6FDA-DMB) PAA prepared, and the obtained Mw from GPC-MALLS and GPC-RI were 35,300 g/mol and 125,000 g/mol, respectively. Particularly, such a mobile phase is also applicable to other PAA samples with different structures, and the final results on molecular weight are also reproducible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Polyamic%20acids" title="Polyamic acids">Polyamic acids</a>, <a href="https://publications.waset.org/abstracts/search?q=Polyelectrolyte%20effects" title=" Polyelectrolyte effects"> Polyelectrolyte effects</a>, <a href="https://publications.waset.org/abstracts/search?q=Gel%20permeation%20chromatography" title=" Gel permeation chromatography"> Gel permeation chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=Mobile%20phase" title=" Mobile phase"> Mobile phase</a>, <a href="https://publications.waset.org/abstracts/search?q=Molecular%20weight" title=" Molecular weight"> Molecular weight</a> </p> <a href="https://publications.waset.org/abstracts/173439/characterization-on-molecular-weight-of-polyamic-acids-using-gpc-coupled-with-multiple-detectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173439.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">54</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">2409</span> Integrative Biology Teaching and Learning Model Based on STEM Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narupot%20Putwattana">Narupot Putwattana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Changes in global situation such as environmental and economic crisis brought the new perspective for science education called integrative biology. STEM has been increasingly mentioned for several educational researches as the approach which combines the concept in Science (S), Technology (T), Engineering (E) and Mathematics (M) to apply in teaching and learning process so as to strengthen the 21st-century skills such as creativity and critical thinking. Recent studies demonstrated STEM as the pedagogy which described the engineering process along with the science classroom activities. So far, pedagogical contents for STEM explaining the content in biology have been scarce. A qualitative literature review was conducted so as to gather the articles based on electronic databases (google scholar). STEM education, engineering design, teaching and learning of biology were used as main keywords to find out researches involving with the application of STEM in biology teaching and learning process. All articles were analyzed to obtain appropriate teaching and learning model that unify the core concept of biology. The synthesized model comprised of engineering design, inquiry-based learning, biological prototype and biologically-inspired design (BID). STEM content and context integration were used as the theoretical framework to create the integrative biology instructional model for STEM education. Several disciplines contents such as biology, engineering, and technology were regarded for inquiry-based learning to build biological prototype. Direct and indirect integrations were used to provide the knowledge into the biology related STEM strategy. Meanwhile, engineering design and BID showed the occupational context for engineer and biologist. Technological and mathematical aspects were required to be inspected in terms of co-teaching method. Lastly, other variables such as critical thinking and problem-solving skills should be more considered in the further researches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomimicry" title="biomimicry">biomimicry</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20approach" title=" engineering approach"> engineering approach</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM%20education" title=" STEM education"> STEM education</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning%20model" title=" teaching and learning model"> teaching and learning model</a> </p> <a href="https://publications.waset.org/abstracts/79439/integrative-biology-teaching-and-learning-model-based-on-stem-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79439.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">255</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">2408</span> Molecular Modeling of 17-Picolyl and 17-Picolinylidene Androstane Derivatives with Anticancer Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanja%20Podunavac-Kuzmanovi%C4%87">Sanja Podunavac-Kuzmanović</a>, <a href="https://publications.waset.org/abstracts/search?q=Strahinja%20Kova%C4%8Devi%C4%87"> Strahinja Kovačević</a>, <a href="https://publications.waset.org/abstracts/search?q=Lidija%20Jevri%C4%87"> Lidija Jevrić</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgenija%20Djurendi%C4%87"> Evgenija Djurendić</a>, <a href="https://publications.waset.org/abstracts/search?q=Jovana%20Ajdukovi%C4%87"> Jovana Ajduković</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the molecular modeling of a series of 24 17-picolyl and 17-picolinylidene androstane derivatives whit significant anticancer activity was carried out. Modelling of studied compounds was performed by CS ChemBioDraw Ultra v12.0 program for drawing 2D molecular structures and CS ChemBio3D Ultra v12.0 for 3D molecular modelling. The obtained 3D structures were subjected to energy minimization using molecular mechanics force field method (MM2). The cutoff for structure optimization was set at a gradient of 0.1 kcal/Åmol. Full geometry optimization was done by the Austin Model 1 (AM1) until the root mean square (RMS) gradient reached a value smaller than 0.0001 kcal/Åmol using Molecular Orbital Package (MOPAC) program. The obtained physicochemical, lipophilicity and topological descriptors were used for analysis of molecular similarities and dissimilarities applying suitable chemometric methods (principal component analysis and cluster analysis).

For example, analyses of transcriptomics and proteomics data enable to gain insights into the molecular differences in tissues exposed to diverse stimuli or test items. Whereas the interpretation of endpoints specifically measuring a mechanism is relatively straightforward, the interpretation of big data is more complex and would benefit from comparing results obtained with diverse analysis methods. The sbv IMPROVER project was created to implement solutions to verify systems biology data, methods, and conclusions. Computational challenges leveraging the wisdom of the crowd allow benchmarking methods for specific tasks, such as signature extraction and/or samples classification. Four challenges have already been successfully conducted and confirmed that the aggregation of predictions often leads to better results than individual predictions and that methods perform best in specific contexts. Whenever the scientific question of interest does not have a gold standard, but may greatly benefit from the scientific community to come together and discuss their approaches and results, datathons are set up. The inaugural sbv IMPROVER datathon was held in Singapore on 23-24 September 2016. It allowed bioinformaticians and data scientists to consolidate their ideas and work on the most promising methods as teams, after having initially reflected on the problem on their own. The outcome is a set of visualization and analysis methods that will be shared with the scientific community via the Garuda platform, an open connectivity platform that provides a framework to navigate through different applications, databases and services in biology and medicine. We will present the results we obtained when analyzing data with our network-based method, and introduce a datathon that will take place in Japan to encourage the analysis of the same datasets with other methods to allow for the consolidation of conclusions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data%20interpretation" title="big data interpretation">big data interpretation</a>, <a href="https://publications.waset.org/abstracts/search?q=datathon" title=" datathon"> datathon</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20toxicology" title=" systems toxicology"> systems toxicology</a>, <a href="https://publications.waset.org/abstracts/search?q=verification" title=" verification"> verification</a> </p> <a href="https://publications.waset.org/abstracts/71479/the-systems-biology-verification-endeavor-harness-the-power-of-the-crowd-to-address-computational-and-biological-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71479.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">278</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">2405</span> "Empowering Minds and Unleashing Curiosity: DIY Biotechnology for High School Students in the Age of Distance Learning"</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20Hugo%20Sanchez%20Rodriguez">Victor Hugo Sanchez Rodriguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amidst the challenges posed by pandemic-induced lockdowns, traditional educational models have been disrupted. To bridge the distance learning gap, our project introduces an innovative initiative focused on teaching high school students basic biotechnology techniques. We aim to empower young minds and foster curiosity by encouraging students to create their own DIY biotechnology laboratories using easily accessible materials found at home. This abstract outlines the key aspects of our project, highlighting its importance, methodology, and evaluation approach.In response to the pandemic's limitations, our project targets the delivery of biotechnology education at a distance. By engaging students in hands-on experiments, we seek to provide an enriching learning experience despite the constraints of remote learning. The DIY approach allows students to explore scientific concepts in a practical and enjoyable manner, nurturing their interest in biotechnology and molecular biology. Originally designed to assess professional-level research programs, we have adapted the URSSA to suit the context of biotechnology and molecular biology synthesis for high school students. By applying this tool before and after the experimental sessions, we aim to gauge the program's impact on students' learning experiences and skill development. Our project's significance lies not only in its novel approach to teaching biotechnology but also in its adaptability to the current global crisis. By providing students with a stimulating and interactive learning environment, we hope to inspire educators and institutions to embrace creative solutions during challenging times. Moreover, the insights gained from our evaluation will inform future efforts to enhance distance learning programs and promote accessible science education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DIY%20biotechnology" title="DIY biotechnology">DIY biotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20school%20students" title=" high school students"> high school students</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20learning" title=" distance learning"> distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemic%20education" title=" pandemic education"> pandemic education</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20research%20student%20self-assessment%20%28URSSA%29" title=" undergraduate research student self-assessment (URSSA)"> undergraduate research student self-assessment (URSSA)</a> </p> <a href="https://publications.waset.org/abstracts/170949/empowering-minds-and-unleashing-curiosity-diy-biotechnology-for-high-school-students-in-the-age-of-distance-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170949.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">68</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">2404</span> An Insight into the Conformational Dynamics of Glycan through Molecular Dynamics Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Veluraja">K.

Molecular recognition processes are attributed to their occurrence on the surface of the cell, sequential arrangement and type of sugar molecules present in the oligosaccharide structure and glyosidic linkage diversity (glycoinformatics) and conformational diversity (glycoconformatics). Molecular Dynamics Simulation study is a theoretical-cum-computational tool successfully utilized to establish glycoconformatics of glycan. The study on various oligosaccharides of glycan clearly indicates that oligosaccharides do exist in multiple conformational states and these conformational states arise due to the flexibility associated with a glycosidic torsional angle (φ,ψ) . As an example: a single disaccharide structure NeuNacα(2-3) Gal exists in three different conformational states due to the differences in the preferential value of glycosidic torsional angles (φ,ψ). Hence establishing three dimensional structural and conformational models for glycan (cartesian coordinates of every individual atoms of an oligosaccharide structure in a preferred conformation) is quite crucial to understand various molecular recognition processes such as glycan-toxin interaction and glycan-virus interaction. The gycoconformatics models obtained for various glycan through Molecular Dynamics Simulation stored in our 3DSDSCAR (3DSDSCAR.ORG) a public domain database and its utility value in understanding the molecular recognition processes and in drug design venture will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glycan" title="glycan">glycan</a>, <a href="https://publications.waset.org/abstracts/search?q=glycoconformatics" title=" glycoconformatics"> glycoconformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=oligosaccharide" title=" oligosaccharide"> oligosaccharide</a> </p> <a href="https://publications.waset.org/abstracts/96790/an-insight-into-the-conformational-dynamics-of-glycan-through-molecular-dynamics-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96790.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">137</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">2403</span> Computing Some Topological Descriptors of Single-Walled Carbon Nanotubes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Bahrami">Amir Bahrami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the fields of chemical graph theory, molecular topology, and mathematical chemistry, a topological index or a descriptor index also known as a connectivity index is a type of a molecular descriptor that is calculated based on the molecular graph of a chemical compound.

Topological indices are used for example in the development of quantitative structure-activity relationships (QSARs) in which the biological activity or other properties of molecules are correlated with their chemical structure. In this paper some descriptor index (descriptor index) of single-walled carbon nanotubes, is determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20graph%20theory" title="chemical graph theory">chemical graph theory</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20topology" title=" molecular topology"> molecular topology</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20descriptor" title=" molecular descriptor"> molecular descriptor</a>, <a href="https://publications.waset.org/abstracts/search?q=single-walled%20carbon%20nanotubes" title=" single-walled carbon nanotubes"> single-walled carbon nanotubes</a> </p> <a href="https://publications.waset.org/abstracts/39279/computing-some-topological-descriptors-of-single-walled-carbon-nanotubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39279.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">338</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">2402</span> DNA Based Identification of Insect Vectors for Zoonotic Diseases From District Faisalabad, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zain%20Ul%20Abdin">Zain Ul Abdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirza%20Aizaz%20Asim"> Mirza Aizaz Asim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rao%20Sohail%20Ahmad%20Khan"> Rao Sohail Ahmad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Luqman%20Amrao"> Luqman Amrao</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiaz%20Hussain"> Fiaz Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasooba%20Hira"> Hasooba Hira</a>, <a href="https://publications.waset.org/abstracts/search?q=Saqi%20Kosar%20Abbas"> Saqi Kosar Abbas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The success of Integrated vector management programmes mainly depends on the correct identification of insect vector species involved in vector borne diseases. Based on molecular data the most important insect species involved as vectors for Zoonotic diseases in Pakistan were identified. The precise and accurate identification of such type of organism is only possible through molecular based techniques like “DNA barcoding”. Morphological species identification in insects at any life stage, is very challenging, therefore, DNA barcoding was used as a tool for rapid and accurate species identification in a wide variety of taxa across the globe and parallel studies revealed that DNA barcoding data can be effectively used in resolving taxonomic ambiguities, detection of cryptic diversity, invasion biology, description of new species etc. A comprehensive survey was carried out for the collection of insects (both adult and immature stages) in district Faisalabad, Pakistan and their DNA was extracted and mitochondrial cytochrome oxidase subunit I (COI-59) barcode sequences was used for molecular identification of immature and adult life stage.This preliminary research work opens new frontiers for developing sustainable insect vectors management programmes for saving lives of mankind from fatal diseases. <p class="card-text"><strong>Keywords:</strong> <a
