In this study, two goals are followed. First, by means of the Generalized Differential Quadrature (GDQ) method, parametric analysis on the vibration characteristics of three-parameter Functionally Graded (FG) beams on variable elastic foundations is studied. These parameters include (a) three parameters of power-law distribution, (b) variable Winkler foundation modulus, (c) two-parameter elasti...

Advances in chemical genetics in the past few years have permitted the formulation of a consistent hypothesis concerning the chemical nature of the "primary" genetic material.1 This material is considered to consist of nucleic acid (usually deoxyribosenucleic acid) and to contain genetic information in a code of prescribed nucleotide sequences. The information is believed to be preserved during...

Several fertility clinics in the United States are experimenting with ooplasm transfer. This technique is hypothesized to enhance fertility in women who have failed conventional in vitro fertilization due to poor embryo development. It involves injection of cellular material (cytoplasm or ooplasm) from a donor egg into the mother’s unfertilized egg prior to fertilization in vitro. The transferr...

Reliable and efficient material transport is one of the basic requirements that affect productivity in industry. For that reason, in this paper two approaches are proposed for the task of intelligent material transport by using a mobile robot. The first approach is based on applying genetic algorithms for optimizing process plans. Optimized process plans are passed to the genetic algorithm for ...

objective(s): short tandem repeat (str) loci are the most informative dna genetic markers for attempting to individualize biological material for application in paternity and forensic cases. materials and methods: blood samples were collected and the total genomic dna was extracted. the dna samples were used for genotyping vwa and tpox str loci using pcr and polyacrylamide gel electrophoresis. ...

garlic (allium sativum .l) has been and is clonally propagated, because it does not produce seed under standard conditions. knowledge of plant recourses genetic diversity can be a first and most important step in achieving breeding program purposes. because of its high accuracy and reproducibility among different genetic diversity assessment techniques amplified fragment length polymorphism (af...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...
