چکیده
1.1 Simple derivation of GBLUP Models for genomic selection are abundant. However, most of them rely (yet not all; [1] ) in a hierarchical formulation in which SNP markers (or haplotypes) have additive effect on the trait of interest [2]. We will focus here in models including biallelic SNP markers. Thus, n markers will have n effects, a1 ... an. Although markers have 2 alleles, a single effect can be defined for each marker according to the notion of substitution effect [3]. For ease of development, substitution effects are centered around 0. Expressions for the values of different genotypes can be found in Falconer [3], and they are (these will be referred to as “allele coding”):

Single Step and Non-Catalytic Process for Formaldehyde Production from Methane using Microchannel Reactor: Theoretical Analysis
Conventionally, methane is reformed into syngas, and subsequently converted into C1-oxygenates (methanol and formaldehyde). A novel option is the catalyst-free single-step conversion of methane to C1-oxygenates. This study presents a comprehensive model of methane partial oxidation to formaldehyde as an intermediate chemical species in methane oxidation process using microreactor. The dependenc...
متن کاملDesign of single-sampling inspection-plan approach by mathematical programming and linear assignment method
This study proposes a new approach for single-sampling plan by determining sample size and acceptance number. The proposed approach is based on a two-step methodology. In the first step: quality management step, different single sampling inspection plans were generated by running an optimization model for different possible acceptance numbers. While, in the second step: Multi-Attribute Decision...
متن کاملSolving systems of nonlinear equations using decomposition technique
A systematic way is presented for the construction of multi-step iterative method with frozen Jacobian. The inclusion of an auxiliary function is discussed. The presented analysis shows that how to incorporate auxiliary function in a way that we can keep the order of convergence and computational cost of Newton multi-step method. The auxiliary function provides us the way to overcome the singul...
متن کاملTheoretical study of catalytic reduction of CO2 with H20 by BOC-MP method
Bond-Order Conservation-Morse Potential (BOC-MP) method is used to carry out the calculationon the CO2+ H20 system. One of the best catalysts for methanol synthesis in catalytic reductionof CO2 with H2O is Cu/ZnO/A1203 whose surface is supported by with some amount of Pd orGa. Reduction of CO2 with H20 on Cu will result in methanol formation; while on Ni will lead tomethane formation. In the me...
متن کاملTheoretical Study of Addition Reaction of Carbene and Zigzag Single-walled Carbon Nanotube
The reaction mechanism between (H2C) and (7, 0), zigzag single-walled carbon nanotubes(ZSWCNTs) on two different orientation of C-C have been studied by semi empirical AM!method. The activation barriers of (H2C) adding to (7, 0) ZSWCNT are computed and compared.The effects of diameters of zigzag SWCNT on their binding energies were studied
