This paper consists of two conceptually related but independent parts. In the first part we initiate the study of k-SAT instances of bounded diameter. The diameter of an ordered CNF formula is defined as the maximum difference between the index of the first and the last occurrence of a variable. We investigate the relation between the diameter of a formula and the tree-width and the path-width ...

Buried pipes in the modern societies are considered as lifelines with a vital and essential role in the human life cycle. The performance of buried pipes is affected by many factors such as ground surface subsidence. In this paper, the effect of subsidence on pipelines is investigated using a three-dimensional numerical modeling developed in FLAC3D software for four types of most commonly used ...

Background and objective: Gentimicin is an antibiotic from the family of Aminoglycosides used in the treatment of infections resulted from Gram-negative bacteria, the use of which is limited due to its nephrotoxicity. In this study the histological effect of cinnamon on the nephrotoxicity resulted from Gentimicin in rats is investigated because of the Antioxidant properties of cinnamon.Material...

 A brass Vortex Tube (VT) with interchangeable parts is used to determine the optimum cold end orifice diameter, main tube length and diameter. Experim...

Scientific work is devoted to research of stress-strain state PD2-9,5 road slabs, reinforced with identical frames made fiberglass reinforcement and metal A500C the 10th diameter. In order verify hypothesis regarding possibility equal-strength replacement composite a smaller diameter, glass 7th diameter was used reinforce slab. To determine actual bearing capacity, due application uniformly dis...

water shortage is the most important factors on crop production in the world. several methods of deficit irrigation are solutions for reduction of irrigation water. to understand the effects of conventional deficit irrigation and partial root zone drying treatments on yield, yield components and water use efficiency of sunflower (farrokh cultivar), one study was carried out. the research was co...

INTRODUCTION Both inferior vena cava (IVC) diameter and the degree of inspiratory collapse are used in the estimation of right atrial pressure. AIM The purpose of this study is to evaluate the utility of IVC diameter, using echocardiography as a marker of volume overload and the relationship between these parameters and N-terminal pro-B natriuretic peptide (NT-proBNP) in patients with systoli...

Zinnia elegans, an annual flowering plant of the genus Zinnia, is one of the best known zinnias. Present study was conducted to evaluate the effect of different growing media on the growth and flowering of Zinnia elegans. Seven different growth media including coconut compost, silt, soil loam, leaf manure, (leaf manure + silt; 2:1), (coconut compost + soil loam; 1:1) and (leaf...

A low-cost CCD camera system for imaging Coulter orifices ranging in diameter between 20 μm and 2 mm has been developed and tested. The imaging system incorporates a 6X magnifying lens for viewing the required range of Coulter orifices and LEDs (Light emitting diodes) lamp for back illuminating the orifices. Geometric optic calculations using Zemax® for the micro-lens interfaced with the camera...
