tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

We find an explicit expression of the Tutte polynomial of an $n$-fan. We also find a formula of the Tutte polynomial of an $n$-wheel in terms of the Tutte polynomial of $n$-fans. Finally, we give an alternative expression of the Tutte polynomial of an $n$-wheel and then prove the explicit formula for the Tutte polynomial of an $n$-wheel.

Bump mapping is a technique that represents the detailed parts of an object surface, such as the skin of a peanut, using the geometry mapping without complex modeling. However, the hardware implementation for bump mapping is very expensive, because a large amount of per pixel computations, including the normal vector shading, is required. In this paper, we propose an effective bump mapping algo...

This approach is equivalent to asking the question, what position, z(t), would the maximum likelihood decoder choose given the noisy bump of activity I(t)? This idea is illustrated in figure 1. Here the red line corresponds to bump at the location of the actual stimulus, U(x(t)). This is then corrupted by noise to give the noisy input profile shown in grey (note that this example uses a high no...

The reminiscence bump is a robust finding in the autobiographical memory literature: Adults recall more events from the second and third decades of life than from other periods. Berntsen and Rubin (2004; Rubin & Berntsen, 2003) proposed a life script account of the reminiscence bump. We extend the life script account by taking a theory-based, life span developmental approach, proposing a life s...

Introduction. The goal of this study was to research the association of femoral bumps and herniation pits with the overlap-ratio of the cross-over sign. Methods. Pelvic X-rays and CT-scans of 2925 patients with good assessment of the anterior and the posterior acetabular wall and absence of neutral pelvic tilt were enrolled in the investigation. Finally pelvic X-rays were assessed for the prese...

OBJECTIVE We describe a series of patients with a previously unreported sonographic finding, the chorionic "bump," which is an irregular, convex bulge from the choriodecidual surface into the first-trimester gestational sac. The pregnancy outcome is investigated in this series of patients and compared with the general population and infertility first-trimester control groups. METHODS We prosp...
