The F1 along with parents of a 4 x 6 line x tester crosses in safflower were studied and seven parameters, i.e., D 2 7 based on 7 characters and D24 based on yield and its 3 direct componenets and mid parent value (MP-Y), F1 mean (F1-Y), relative heterosis (RH-Y), biparental average GCA (MPGCA-Y) and SCA effect (SCA-Y) for yield were estimated. Twenty four selected crosses were studied for segr...

In the past 53 years, many efforts have been contributed to develop and demonstrate properties of reinforced composite materials. The ever-increasing use materials through engineering structures needs proper analysis mechanical response these structures. proposed work, we an exact form Stress components Displacement a Griffith crack at interface Isotropic Orthotropic half-space bounded together...

In this paper, the strain-based and stressbased methods for solving optimal orientation problems of orthotropic materials are studied. Closed form solutions for both methods are derived and classified. The optimal orientation of both shear “weak” and some shear “strong” orthotropic materials may coincide with the major principal stress direction in the stress-based method. Similar results from ...

The Magnetic resonance electrical impedance tomography (MREIT) is a new medical imaging method combining electrical impedance tomography (EIT) and current injection MRI technique. In this paper, we show the uniqueness in MREIT problem with an orthotropic conductivity under the hypothesis that the ratios of conductivities are known. Based on an effective numerical differentiation method and an a...

Received January 2009 Accepted November 2010 INTRODUCTION Ureteropelvic-junction-obstruction (UPJO) occurs in 22% to 37% of ectopic kidneys.(1) Laparoscopic dismembered pyeloplasty (LDP) is an acceptable treatment for UPJO in pediatric patients with orthotropic kidneys.(2,3) Laparoscopic flap techniques have less favorable results than LDP in adult patients with orthotropic kidneys.(3) To our b...

The weakness of existing relationships correlating off-axis modulus of elasticity E� to shear mod­ ulus G12 for wood composite panels is demonstrated through presentation of extensive experimental data. A new relationship is proposed that performs better than existing equations found in the literature. This relationship can be manipulated to calculate the shear modulus G12 of orthotropic specim...

In this paper, a new methodology for identifying numerous elastic parameters of an orthotropic material from a single structural test is presented. At the heart of the methodology is the self-learning algorithm which is to extract various stress-strain relationships from a single structural test and train a neural network with the relationships in finite element framework. The constitutive matr...

INTRODUCTION: The rapid expansion of the at-risk population for pathological fracture has led to increased interest in the ability to predict the mechanical behavior of trabecular bone as it relates to routine nontraumatic loading. A large body of work has established that the mechanical behavior of cancellous bone, particularly stiffness and strength under monotonic loading, is strongly depend...
