Past, Present and Future Molecular Approaches to Improve Yield in Wheat

This chapter addresses the development and use of molecular markers for yield enhancement in wheat. Since their key goal for breeding is to maximize yield, extensive efforts have been made toward the improvement of yield. Agronomic traits related to yield, yield-related, disease resistance, and abiotic stresses are considered to be quantitative traits (QTLs), also known as complex traits, because they are controlled by numerous genes and are affected by environmental factors. Researchers have been studying such traits in the past decades for the development of molecular markers which can be used in various wheat breeding studies mainly involving restriction fragment length polymorphism (RFLP), simple sequence repeat (SSR), single nucleotide polymorphism (SNP), random amplified polymorphic DNA (RAPD), and amplified fragment length polymorphism (AFLP). Furthermore, the advent of next-generation sequencing (NGS) has accelerated the discovery of agronomically important genes. All of the technologies have enabled great advances for increasing the productivity of wheat. Here, the past history of first-generation sequencing, present status of second-generation sequencing, and future potential of translational genomics linked to the yield will be discussed

The Biblical Approach to Church Growth Through Personal Evangelism

The greatest commandment of the Lord is preaching the gospel all over the world. It is the duty of all Christians to preach the gospel to the world. If we are negligent about it, we may lose God\u27s blessings. When we study the way Jesus preached the gospel, we see that He personally met people individually and called them to become His disciples. Those who met Jesus personally became evangelists themselves, proclaimed God\u27s Word, and expanded the church. Jesus built the church so that it would do His work after He left this earth. Therefore, it is the mission of the church to go out and preach the gospel. To carry out this mission the author\u27s church held Evangelism Mobilization Sunday, through which every church member could participate in evangelism and realize the importance of training. With the example of Sung Dong church members, this thesis shows the close relationship between personal evangelism and church growth

Free Vibration of Layered Circular Cylindrical Shells of Variable Thickness Using Spline Function Approximation

Free vibration of layered circular cylindrical shells of variable thickness is studied using spline function approximation by applying a point collocation method. The shell is made up of uniform layers of isotropic or specially orthotropic materials. The equations of motions in longitudinal, circumferential and transverse displacement components, are derived using extension of Love's first approximation theory. The coupled differential equations are solved using Bickley-type splines of suitable order, which are cubic and quintic, by applying the point collocation method. This results in the generalized eigenvalue problem by combining the suitable boundary conditions. The effect of frequency parameters and the corresponding mode shapes of vibration are studied with different thickness variation coefficients, and other parameters. The thickness variations are assumed to be linear, exponential, and sinusoidal along the axial direction. The results are given graphically and comparisons are made with those results obtained using finite element method

Einstein Structure of Squashed Four-Spheres

It is known that the moduli space of Einstein structures is an isolated point so that an Einstein structure has no infinitesimal Einstein deformations. We examine the rigidity of the Einstein structure by considering deformations of the round four-sphere $\mathbb{S}^4$. We show that any deformation of the round four-sphere $\mathbb{S}^4$ causes it to deviate from the Einstein structure, except trivial deformations at most only changing the size of the sphere.Comment: v2: 22 pages, 1 figure, references adde
