Grounding of the Longitudinal Distance from the Plow Corps to the Center of the Disk Skimmer | Chapter 2 | Innovations in Science and Technology Vol.8

  The theoretical grounding of the longitudinal distance from the plough corps to the centre of the disc skimmer is discussed in this article. The longitudinal distance (I) from the tip of the ploughshare to the centre (Od) of the disc and the determination of the distance (y) of the soil discarding were theoretically substantiated. The angle () of attack, depth (hg) stroke, radius (r) of the sphere, radius (R) of the disc, and angle (k) of the ploughshare installation to the furrow wall are all factors that influence the longitudinal distance.

Study About Size Dimorphism and Directional Selection in Forest Millipedes | Chapter 2 | New Visions in Biological Science Vol.9

 In the diplopod genus Centrobolus, sexual size dimorphism (SSD) has a positive connection with body size. Spirobolida diplopod species can be identified using size criteria. The key components of interspecific variation in diplopod species are length, width, and rings. In six species, interspecific size variation was estimated, and data sets were checked for normality. All of the data that was observed and tested was normal. The goal was to use MEDCALC® to measure and compare intersexual variation (coefficients of variation) in length and width in nine species. There was a considerable directional selection for slender males in C. digrammus, C. inscriptus, and C. silvanus.

Cracking for Low-reinforced RC Members under Uniaxial Tension | Chapter 5 | Emerging Trends in Engineering Research and Technology Vol. 3

Given the random nature of crack formation, research into reinforced concrete members in the context of cracking behavior proves difficult. Therefore, widely accepted methodologies for predicting crack characteristics, e.g. crack width and spacing and number of cracks, have not been developed yet. Furthermore, cracking for members strained until high degrees of elongation, as takes place during earthquakes, has not been investigated before. This experimental work aims to look into the impact, primarily of tensile deformation’s mechanical factor, in terms of cracking behaviour. Four test specimens were strained under uniaxial tensile loading. The degrees of elongation used were equal to 10‰, 20‰, 30‰ and 50‰. Useful conclusions concerning cracking behaviour are derived.
