Desain Filter Aktif Dengan Skema Fuzzy Logic Controller Untuk Mereduksi Harmonisa

Harmonics are known as one of the causes of decline in the quality of the electrical power system, which can cause a negative impact on electronic equipment. Harmonics reduction that has been achieved with the passive filters is not quite satisfactory, thus development of active filters is required. This research proposes the use of parallel active filter design using a three-level inverter with the scheme of Fuzzy Logic Controller (FLC) that is used to reduce harmonics. The use of three stages Multilevel Inverter (MLI) on parallel active filter has several advantages that are lowering harmonic distortion and reducing stress switching. From the simulation results, it was obtained that three parallel active filters were capable of reducing the level of harmonic currents and voltages at the source; THDi before installation of the filter was equal to 26,16% and can be lowered to 2,42%. While THDv was reduced from 0,45% to 0,17%. Fifth-order harmonics is the most disturbing harmonic component, in which the value of IHDi beforeinstalling the filter is equal to 21,44% and reduce to 1,2% after the installation of the active filter

Pengaruh Jarak Tanam Terhadap Pertumbuhan Dan Hasil Tanaman Padi (Oryza Sativa L.) Pada Pola Jarak Tanam Yang Berbeda Dalam Sistem Tabela

The study aimed to find plant spacing for better growth and yield of wetland rice crops under direct seeded planting system. The study was arranged in a Randomized Block design with two factors i.e. two different spatial plantings and three kinds of Jajar Legowo patterns. The plant spacing of 25 cm x 25 cm with Jajar Legowo pattern of 2:1 produced highest grain yield (8.21 ton ha-1) followed by the plant spacing of 20cm x 20cm with Jajar Legowo pattern of 3:1 (7.21 ton ha-1). Jajar Legowo pattern of 3:1 resulted in better plant height (74.80cm), similarly plant spacing of 25cm x 25 cm also had same plant height, more tiller number (30.69) and panicles per clump, longer panicle length and more grain number

SCREENHOUSE EVALUATION OF GROUNDNUT GENOTYPES FORNITROGEN FIXATION AND MAIZE VARIETIES FOR NITROGENUPTAKE EFFICIENCY

Phosphorus is important in the symbiotic association with the bacteria rhizobium, there by fixing atmospheric nitrogen. Due to low availability of the fertility status of most savannah soils, the objectives of this research were therefore; to estimate biological nitrogen fixation by the groundnut genotypes under low and high phosphorus conditions and to determine the nitrogen uptake efficiency of some selected maize varieties. To achieve these objectives, a potted experiment was conducted in the screenhouse of the Department of Soil Science, Ahmadu Bello University Samaru, Zaria. The treatments consisted of a combination of five genotypes of groundnut namely; (Samnut 10, Samnut 11, Samnut 21, Samnut 22 and Samnut 23) and three varieties of maize (TZE, TZEE, and Obatampa). The groundnut genotypes had 60kg P2O5 ha-1 (13.2 mgP/kg soil) and 0kg P2O5 ha-1 (0 mgP/kg soil), the maize varieties had 75 kg P2O5 ha-1 (16.5 mgP/ kg soil) and 0 kg P2O5 ha-1 (0 mgP/ kg soil) levels. The treatments were repeated three times and laid down in a Completely Randomised Design. There was no significant difference in the amount of atmospheric nitrogen fixed by the groundnut genotypes. However, Phosphorus application significantly increased nitrogen fixation compared to the control, therefore 60kg P2O5 ha-1 is concluded for higher nitrogen fixation in the soil.The effect of maize varieties in relation to nitrogen uptake efficiency was significant statistically, this result shows that the varieties that grow and develop extra early takes up more nitrogen faster than the late varieties and early varieties

A Comparative Analysis on the Innate Immune Responses of <i>Cirrhinus mrigala</i> Challenged with <i>Pseudomonas aeruginosa</i> and <i>Fusarium oxysporum</i>

Microbes are the most significant ubiquitous pathogens that cause serious infections in freshwater fish, leading to tremendous economic losses. The present study was designed to investigate the extent of changes in cytokine expression, hemato-biochemical parameters, and tissue histology of Cirrhinus mrigala (C. mrigala) challenged with Pseudomonas aeruginosa (P. aeruginosa) and Fusarium oxysporum (F. oxysporum). Fish were divided into three major groups: control, P. aeruginosa-challenged, and F. oxysporum-challenged. The infection in both challenge assays was allowed to progress until 7 days post infection. Upregulated expression of TNF-α and IL-1β was found in blood, gills, livers, and kidneys of the challenged fish. Significant differences were noted in hematological parameters of challenged fish. Alanine aminotransferase, aspartate aminotransferase, and alkaline aminotransferase levels also showed significant differences in infected and control groups. An increase in serum albumin and globulin and a decrease in total protein were noted in infected groups as compared to the control group. Severe histological alterations were noted in gill, liver, and kidney tissues of the infected groups as compared to control. The order of histological alteration index for P. aeruginosa challenge was liver &gt; kidney &gt; gills, and for F. oxysporum challenge it was kidney &gt; liver &gt; gills. These changes in fish infected by P. aeruginosa and F. oxysporum can be used as an effective and subtle index to monitor the physiological and pathological conditions of fish

Determination of Saturated Hydrocarbon from Nigerian Crude Oil from Selected Oil Wells: A Comparative Study

The saturated hydrocarbons were isolated from the crude oil samples by the use of SARA separation and column chromatography methods. The fractions obtained were identified using GC-MS. The result shows that the saturated hydrocarbons presence in the samples indicate that all the samples spectra indicated the presence of Trans-decalin-2-methyl, Dodecane, Tridecane, Tetradecane, Pentadecane, Hexadecane, Octadecane, Nonadecane and Eicosane, all at a minimum quality of correlation of 70%.  The result of the GC-MS indicated that sample D has the highest number of saturated hydrocarbons presence in a minimum quality of % correlation of 70% and sample E has the lowest amount of saturated hydrocarbons. Keywords: Crude oil drilling, GC-MS, Sara analysis, Saturated hydrocarbons, Trans-decalin-2-methy

Compound-Specific Radiocarbon Analysis by Elemental Analyzer–Accelerator Mass Spectrometry: Precision and Limitations

[EN]We examine instrumental and methodological capabilities for microscale (10−50μg of C) radiocarbon analysisof individual compounds in the context of paleoclimate and paleoceanography applications, for which relatively high-precisionmeasurements are required. An extensive suite of data for14C-free and modern reference materials processed using differentmethods and acquired using an elemental-analyzer−accelerator-mass-spectrometry (EA-AMS) instrumental setup at ETHZurich was compiled to assess the reproducibility of specific isolation procedures. In order to determine the precision, accuracy,and reproducibility of measurements on processed compounds, we explore the results of both reference materials and threeclasses of compounds (fatty acids, alkenones, and amino acids) extracted from sediment samples. We utilize a MATLAB codedeveloped to systematically evaluate constant-contamination-model parameters, which in turn can be applied to measurementsof unknown process samples. This approach is computationally reliable and can be used for any blank assessment of small-sizeradiocarbon samples. Our results show that a conservative lower estimate of the sample sizes required to produce relativelyhigh-precision14C data (i.e., with acceptable errors of 0.5, a precision of 2% can be achieved for alkenone and fatty acid samples containing≥15 and 10μg of C, respectivel
