Research ArticleOpen accessEvery word in the titleLeveling Process of Total Electron Content (TEC) Using Malaysian Global Positioning System (GPS) DataY. Norsuzila, M. Abdullah, M. IsmailThe signals from the satellites of the Navstar Global Positioning System (GPS) travel through the earth's ionosphere on their way to GPS receivers. However, ionospheric delay is one of the main sources of error in GPS. The magnitude of the ionospheric delay is influenced by the Total Electron Content (TEC) along the radio wave path from a GPS satellite to … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,768 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Reduced- Protein Diets at Constant Total Sulfur Amino Acids: Lysine Ratio on Pullet Development and Subsequent Laying Hen PerformanceFariborz Khajali, M. Faraji, Saeid Karimi DehkordiThe effect of using a low protein regime in pullet development and subsequent layer performance was studied. The experiment consisted of two periods of rearing and laying. Two hundred and sixty Hy-line W36 chicks were used. In the rearing period, dietary protein level and ME content series of the control group used during starter (18-42), grower (43-63) and developer (64-119d) … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,072 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Polarity of Organic Solvents in Coriander Seed Powder (Coriandrum Sativum) Extract is Dependent on their Content of Beta-Carotene, Total Phenolics, Flavonoids, Antioxidants, and Antibacterial PropertiesUcop Haroen, Syafwan, Agus Budiansyah, Kiki KurniawanAttempts to develop alternative antibiotics from herbal plants, especially those originating from spice plants that contain active compounds, are crucial to improve livestock health and support the growth of livestock to reach their genetic potential. This study aims to examine the effects of utilizing different solvent polarities on the solubility of coriander seed secondary metabolite chemicals, which are associated with … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 6 Nov 2025 · 2,338 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Purification Technology and Antioxidant Activity of Total Flavonoids from Sea Buckthorn LeavesJiale Shan, Yang Liu, Pu Zhao et al.China is rich in sea buckthorn (Hippophae rhamnoides L.)resources and a large amount of sea buckthorn fruit is used to extract oil andjuice every year. However, Sea Buckthorn Leaves (SBL), which are full offlavonoids, are discarded as waste. To make full use of resources and turn waste into valuables, theoptimal purification process of flavonoids from SBL was studied and theantioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 27 Aug 2022 · 6,082 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDistribution of Total Mercury in the Sedimentary Environment in Lake Ahémé, Southern Benin (West Africa)Julien Gnonlonfoun Adounkpe, N. B. Nadia Azon, Hermione W. Degila, Peace HounkpeThis study focuses on the spatio-temporal assessment of mercury pollution of the sedimentary environment of Lake Ahémé in southwestern Benin Republic. Sediment samples were taken from 32 sites in July 2018 and then in December 2019, covering the two major climatic seasons of the southern area of the country. Sampling was done according to a grid design of the entire … …American Journal of Environmental Sciences, Vol. 17, Issue 5 · 26 Dec 2021 · 6,902 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAttenuated Total Reflectance-Fourier-Transform Infrared Microspectroscopy a Rapid Method for Microbial Strain CharacterizationMeshref Awad AlruwailiFourier-Transform Infrared (FTIR) spectroscopy and BHI 50CH were used to identify bacteria of the Lactobacillus (L.) at the species level. A previously developed method for measuring FTIR spectra and a strategy for their analysis provided the basis for selecting the FTIR spectra of reference bacterial strains and created a spectral library. The research was launched in which the spectra collected … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 8 Jun 2013 · 7,629 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContribution of Primary Spikes Vs Tillers to Total Deoxynivalenol in Harvested Grain of Wheat and BarleyPravin Gautam, Scott Halley, Jeffrey M. SteinFormation of higher number of tillers is desirable for higher grain yield in both wheat and barley; tillers have delayed physiological development. Studies addressing the contribution of secondary tillers in final DON concentration for wheat and barley are limited. This project aims to improve our understanding of the relationship between FHB symptoms and DON concentration by examining the contribution of … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 25 Jul 2012 · 7,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,240 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleControl Strategy for Discontinuous Conduction Mode Boost Rectifier with Low Total Harmonic Distortion and Improved Dynamic ResponseH.S. AthabDue to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. Problem statement: The line current however, shows considerable distortion when the peak input voltage is close to the output voltage, As a result, the input power factor is poor. This study proposes a simple, low-cost method to reduce the line harmonics. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,424 accessesView PDFCite
