DGAT1 is considered to be the key enzyme in controlling the synthesis of triglycerides in adipocytes. This enzyme catalyzes the final step of triglyceride synthesis (transform triacylglycerol (DAG) into triacylglycerol (TAG). A total of 20 DGAT1 gene sequences and corresponding amino acids belonging to 4 species include cattle, goats, sheep and yaks were analyzed, and the differentiation within and among the species was also studied. The length of the DGAT1 gene varies greatly, from 1527 to 1785 bp, due to deletion, insertion, and stop codon mutation resulting in elongation. Observed genetic diversity was higher among species than within species, and Goat had more polymorphisms than any other species. Novel amino acid variation sites were detected within several species which might be used to illustrate the functional variation. Differentiation of the DGAT1 gene was obvious among species, and the clustering result was consistent with the taxonomy in the National Center for Biotechnology Information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DGAT1gene" title="DGAT1gene">DGAT1gene</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatic" title=" bioinformatic"> bioinformatic</a>, <a href="https://publications.waset.org/abstracts/search?q=ruminnants" title=" ruminnants"> ruminnants</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnology%20information" title=" biotechnology information"> biotechnology information</a> </p> <a href="https://publications.waset.org/abstracts/29456/bioinformatics-analysis-of-dgat1-gene-in-domestic-ruminnants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29456.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">491</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> Reducing Total Harmonic Content of 9-Level Inverter by Use of Cuckoo Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Enayati">Mahmoud Enayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirous%20Mohammadi"> Sirous Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a novel procedure to find the firing angles of the multilevel inverters of supply voltage and, consequently, to decline the total harmonic distortion (THD), has been presented. In order to eliminate more harmonics in the multilevel inverters, its number of levels can be lessened or pulse width modulation waveform, in which more than one switching occur in each level, be used. Both cases complicate the non-algebraic equations and their solution cannot be performed by the conventional methods for the numerical solution of nonlinear equations such as Newton-Raphson method. In this paper, Cuckoo algorithm is used to compute the optimal firing angle of the pulse width modulation voltage waveform in the multilevel inverter. These angles should be calculated in such a way that the voltage amplitude of the fundamental frequency be generated while the total harmonic distortion of the output voltage be small. The simulation and theoretical results for the 9-levels inverter offer the high applicability of the proposed algorithm to identify the suitable firing angles for declining the low order harmonics and generate a waveform whose total harmonic distortion is very small and it is almost a sinusoidal waveform. <p class="card-text"><strong>Keywords:</strong> <a
