to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...

Internal iliac artery (IIA) shows frequent variations in its branching pattern. We saw variations in the branching pattern of right IIA in a male cadaver. The IIA divided into anterior and posterior divisions. The branches of the anterior division included umbilical artery, inferior vesical artery, obturator artery. The other branches arose from posterior trunk such as iliolumbar, lateral s...

This paper presents the results of a numerical study aimed at assessing effectiveness an innovative steel modular retrofit system on improving in-plane lateral capacity unreinforced masonry (URM) load-bearing structures. The investigated solution consists frames fastened to external surface piers through chemical anchors. Distinct element models are built and calibrated against experimental dat...

background: in this experimental study, the radiographic and biomechanical characteristics of osteoperforated rabbit tibia during bone repair period were investigated. materials and methods: using dental drills, 2 mm holes were drilled at the mid-shaft of right tibia in 12 new zealand white rabbits. the left tibia was intact and selected as the control. x-rays of the left and right tibias were ...

When compared to traditional reinforced concrete constructions on level surfaces, buildings situated hills with slopes require additional consideration, particularly when seismic loading is an important factor. In hilly slopes, the ground-level columns of structures have different heights due nature slope, which leads a short column effect. This paper represents experimental and analytical inve...

Variation in equine hoof conformation between farriery interventions lacks research, despite associations with distal limb injuries. This study aimed to determine linear and angular hoof variations pre- and post-farriery within a four to six week shoeing/trimming interval. Seventeen hoof and distal limb measurements were drawn from lateral and anterior digital photographs from 26 horses pre- an...

BACKGROUND The major objective of the present study is to investigate the differences in the load and strain changes in the intertrochanteric region of human cadaveric femora between the loss of medial or lateral wall and after treatment with proximal femoral nail antirotation (PFNA). METHODS After measuring the geometry of the proximal femur region and modeling the medial or lateral wall def...
