Design strategies to enhance modern irrigation practices, reduce energy consumption, and improve water use efficiency crop yields are fundamental for sustainability. Concerning Center-Pivot Irrigation Systems, different design procedures aimed at optimizing have been proposed. Recently, following a gradually decreasing sprinkler spacing along the pivot lateral with constant diameter flow rate, ...

www.americanscientist.org W constitutes a dangerous equation? There are two obvious interpretations: Some equations are dangerous if you know them, and others are dangerous if you do not. The first category may pose danger because the secrets within its bounds open doors behind which lies terrible peril. The obvious winner in this is Einstein’s iconic equation e = mc2, for it provides a measure...

Purpose The purpose of this study was to evaluate the dispersion of intravitreally injected solutions and investigate the influence of varying injection techniques. Methods This was a prospective study using enucleated porcine eyes and ultra-high-resolution computed tomography (UHRCT) scanning to visualize iomeprol intravitreal dispersion. Sixty eyes were divided over 12 different groups acco...

To achieve higher blast furnace (BF) main trough availability and to minimize the frequency of reparations is a key concern in steelmaking industry. For this purpose, strategies assess refractory wear are required, which heavily influenced by temperature linings. In work, mathematical model transient behaviour cross-section BF during complete campaign presented. The scope investigate effect tha...

The initial stages of fault development have been recognized in laboratory experiments, but not at seismogenic depths. To fully understand how faults initially develop and begin to evolve, one needs to first recognize and then observe the emerging structure. Recognizing the birth of a fault requires a priori knowledge of the regional tectonics, geologic structure, and seismic history. This info...

Absmct PSK real number codes for the Rayleigh fading channel were proposed in [I]. This paper tabulates the detailed mapping of sc*me simple full-diversity low-delay codes in the original and the manually refined forms. The performance is examined by simulation at various interleaving depths. For the codes considered, the manually refined ones are found to be easy to implement and offer very li...

Given a set P = {p1, . . . , pn} of points and a point q in the plane, we define a function ψ(q) that provides a combinatorial characterization of the multiset of values {|P ∩Hi|}, where for each i ∈ {1, . . . , n}, Hi is the open half-plane determined by q and pi. We introduce two new natural measures of depth, perihedral depth and eutomic depth, and we show how to express these and the well-k...

As vital components of habitat for stream fishes, pools are often monitored to follow the effects of enhancement projects and natural stream processes. Variations of water depth with discharge, however, can complicate monitoring changes in the depth and volume of pools. To subtract the effect of discharge on depth in pools, residual depths can be measured. Residual depth is the difference in de...

results the mean distances between the crestal bone and the implant shoulder in group 1 were 1.01, 1.44, and 1.93 mm at the implant placement time, and at the 6 and 12-month postoperative intervals, respectively. in group 2, these distances were 1.35, 1.20, and 1.41 mm, respectively. there were no significant differences in the marginal bone resorption between the two groups (p > 0.05). conclus...
