Research ArticleOpen accessIn the author namesA Clean-Green Synthesis of Platinum Nanoparticles Utilizing a Pernicious Weed Lantana (Lantana Camara)Musthafa O. Mavukkandy, Sudip Chakraborty, Tasneem Abbasi, Shahid A. AbbasiA rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 23 Feb 2016 · 10,447 accessesView PDFCite
Research ArticleOpen accessIn the author namesApplication Specific Integrated Circuits Design and Implementation of Rademacher and Walsh FunctionsA. Abbasi, A. R.M. Alamoud, S. A. AbbasiThe orthogonal functions, specially the Rademacher and Walsh functions are being increasingly used in Digital Signal Processing (DSP). Today’s DSP applications require fast processing time in order to meet the challenges of the real time systems. State-of-the-art implementation technologies are therefore being used. This study describes the design and implementation of Rademacher and Walsh functions targeted to the state-of-the-art Cell … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 7 Jan 2014 · 7,340 accessesView PDFCite
Research ArticleOpen accessIn the author namesGenetic Polymorphism Exon 9-11 at the Leptin Gene Receptor in Breeder Hens of Mazandaran Native FowlsHossein Ali Abbasi, Shahabodin Gharavysi, Rohullah AbdullahpourProblem statement: Leptin a 16 kD protein synthesized by white adipose tissue and involved in regulation of feed intake, energy balance, fertility and immune function. In order to evaluate the leptin gene receptor polymorphism, we have used a Restriction Fragment Length Polymorphism (RFLP) method. Approach: Blood samples were collected from randomly chosen 100 native fowls breeding station of Mazandaran. The … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 17 Sep 2011 · 7,700 accessesView PDFCite
Research ArticleOpen accessIn the author namesDetection of Polymorphism at the Insulin Like Growth Factor-I Gene in Mazandaran Native Chicken using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism MethodHossein Ali Abbasi, Mohsen KazemiProblem statement: Molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in chickens. The Insulin like Growth Factor-I (IGF1) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. Approach: In the present study polymorphism of the promoter and 5' untranslated region of IGF-1 gene of Mazandaran … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 8 Aug 2011 · 7,627 accessesView PDFCite
Research ArticleOpen accessIn the author namesStudy of the Effects Irrigation Water Sanity and pH on Production and Relative Absorption of some Elements Nutrient by the Tomato PlantHossein Afshari, Shahram Ashraf, Abdol Ghaffar Ebadi et al.Problem statement: This study was conducted to examine the effects of irrigation water pH and Salinity on the growth and absorption of P, Na, Ca, K by tomato. Approach:The study includes two Salinity and pH factors and is consisted from 12 treatment and three repetitions. Tomato seeding grown in foam trays were transplanted in the joune 2010 to bags filled … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,695 accessesView PDFCite
Research ArticleOpen accessIn the author namesVHDL Modeling, Simulation and Prototyping of a Novel Arbitrary Signal Generation SystemS. A. Abbasi, A. R.M. Alamoud, J.M. Al ShahraniProblem statement: Arbitrary signal generators play an important role in many applications. Several different techniques utilizing both analog and digital approaches are being used for the generation of periodic signals. However, all of them suffer from many drawbacks. In this study, we present modeling, simulation and prototyping of a novel periodic arbitrary signal generation system using FPGAs. The proposed system … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,755 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffect of Impact Level and Fruit Properties on Golden Delicious Apple BruisingArzhang Javadi, Ebrahim Ahmadi, Mohammad Hossein Abbaspour-Fard et al.Problem Statement: Bruise damage is a major cause of fruit quality loss. Bruises occur under dynamic and static loading when stress induced in the fruit exceeds the failure stress of the fruit tissue. Statistical bruise estimation models were constructed to calculate Golden Delicious apple bruise volume with respect to fruit properties. Approach: The regression models were built based upon impact … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,259 accessesView PDFCite
Research ArticleOpen accessIn the author namesAsymptotic Distribution of Coefficients of Skewness and KurtosisNarges AbbasiProblem statement: In literature, a classic method which has been used to recognize the distribution so far is the measurement of its skewedness and kurtosis. However, there remains a question: how would these measurements work for skewed normal distribution when the size of the sample is large? Approach: This research aimed to determine the asymptotic distribution of skewedness and kurtosis … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 9,582 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Tillage Methods on Soil Fragmentation in Loamy-Clay SoilsYousef Abbaspour-Gilandeh, Vali Rasooli Sharabiani, Ahmad KhalilianProblem statement: Soil fragmentation is a primary aim in tillage in order to create a favorable soil environment for crop growth.
