Geometric Effect of Asperities on Shear Mechanism of Rock Joints

Three-dimensional tracking of changes of asperities is one of the most important ways to illustrate shear mechanism of rock joints during testing. In this paper, the changes of the role of asperities during different stages of shearing are described by using a new methodology for the characterization of the asperities. The basis of the proposed method is the examination of the three-dimensional roughness of joint surfaces scanned before and after shear testing. By defining a concept named ‘tiny window’, the geometric model of the joint surfaces is reconstructed. Tiny windows are expressed as a function of the x and y coordinates, the height (z coordinate), and the angle of a small area of the surface. Constant normal load (CNL) direct shear tests were conducted on replica joints and, by using the proposed method, the distribution and size of contact and damaged areas were identified. Image analysis of the surfaces was used to verify the results of the proposed method. The results indicated that the proposed method is suitable for determining the size and distribution of the contact and damaged areas at any shearing stage. The geometric properties of the tiny windows in the pre-peak, peak, post-peak softening, and residual shearing stages were investigated based on their angle and height. It was found that tiny windows that face the shear direction, especially the steepest ones, have a primary role in shearing. However, due to degradation of asperities at higher normal stresses and shear displacements, some of the tiny windows that do not initially face the shear direction also come in contact. It was also observed that tiny windows with different heights participate in the shearing process, not just the highest ones. Total contact area of the joint surfaces was considered as summation of just-in-contact areas and damaged areas. The results of the proposed method indicated that considering differences between just-in-contact areas and damaged areas provide useful insights into understanding the shear mechanism of rock joints.Hydro-Québec (FONCER-INFRA Grant

Ferromagnetic semiconductor single wall carbon nanotube

Possibility of a ferromagnetic semiconductor single wall carbon nanotube (SWCNT), where ferromagnetism is due to coupling between doped magnetic impurity on a zigzag SWCNT and electrons spin, is investigate. We found, in the weak impurity-spin couplings, at low impurity concentrations the spin up electrons density of states remain semiconductor while the spin down electrons density of states shows a metallic behavior. By increasing impurity concentrations the semiconducting gap of spin up electrons in the density of states is closed, hence a semiconductor to metallic phase transition is take place. In contrast, for the case of strong coupling, spin up electrons density of states remain semiconductor and spin down electron has metallic behavior. Also by increasing impurity spin magnitude, the semiconducting gap of spin up electrons is increased.Comment: 10 pages and 9 figure

Modelling extreme precipitation projections under the effects of climate change: case study of the Caspian Sea

Abstract Climate change is expected to alter climate extremes. This paper evaluates future changes in extreme precipitation events over the Caspian Sea, where the changes are noticeable due to its geographical location and remoteness from the ocean. Using bias-corrected data from the Coupled Model Intercomparison Project Phase 6 and extreme value analysis, this study shows increased precipitation from 18.48 mm/month in 1980–2014 to 19.50–19.82 mm/month in 2015–2100, depending on the climate scenario. Additionally, extreme events in the future are projected to increase over the sea due to climatic changes, depicting the emergence of droughts/floods that could occur more frequently in the region.Abstract Climate change is expected to alter climate extremes.

Development of a perceptually uniform physical scale for visual assessment of specular gloss

Measuring gloss, visually or instrumentally, has been a challenge in many manufacturing and service industries. However, there exists no standardized method for visual evaluation of equidistance specular gloss. This study aimed to design and prepare a psychometric visually equispaced specular gloss scale for the visual measurement of gloss or any other geometric appearance attribute. To this end, a series of lithographically printed black papers, with different levels of gloss from low to high, were prepared to constitute a visually uniform specular gloss scale. Fourteen observers visually quantified the scale in a unidirectional illumination at three different geometries. Analyzing the results shows that the 60° geometry can quantify the equivalent specular gloss efficiently. A uniform specular gloss scale was prepared by assessing the prepared scale visually under the unidirectional illumination at the 60° geometry. Such a visually uniform specular gloss scale could be employed to develop a standard visual evaluation method of specular gloss in all related industries.submittedVersio

Effects of dietary Kemin multi-enzyme on growth, body composition and some blood biochemical factors of Carassius auratus

Exogenous multi-enzyme supplementations can eliminate the effects of antinutritional factors and improve the growth performance of aquatic animals. The purpose of this study was to investigate utilizing Kemin multi-enzyme supplementation in the diet and its effects on growth factors, body composition, and some blood biochemical parameters in Carassius auratus gibelio. The experiment was conducted in a completely randomized experimental design with 5 treatments and 3 replications. The Kemin at 4 levels of 0, 250, 500, 750, and 1000 mg/kg was added to the diet and given the experimental diets to fishes for 8 weeks and growth factors, Weight growth percent (WGP), specific growth rate (SGR), feed conversion ratio (FCR), Condition factor (CF), Protein efficiency ratio (PER) were studied. Body composition and blood biochemical factors (glucose, total protein, albumin, cholesterol, and triglyceride) were measured and evaluated. Different treatments of CF were not significantly different from each other (P> 0.05). But WGP, SGR, FCR and PER, the enzyme levels of 500, 750, and 1000 mg/kg were significantly different from the control group (P 0.05). Based on the results of this study, it seems that Kemin multi-enzyme supplementation diets can improve the growth and FCR in Carassius auratus gibelio

Integrin-Specific Stimuli-Responsive Nanomaterials for Cancer Theranostics

Background: Cancer is one of the leading causes of death worldwide.

Methods: Stimuli-responsive nanoparticles have shown great capacity to be used as a powerful strategy for cancer treatment, diagnostic, as well as theranostic. Nanocarriers are not only able to respond to internal stimuli such as oxidative stress, weakly acidic pH, high temperature, and the high expression of particular enzymes, but also to external stimuli such as light and paramagnetic characteristics to be exploited. Results: In this work, stimulus-responsive nanocarriers functionalized with arginine-glycine-aspartic acid (Arg-Gly-Asp) sequence as well as mimetic sequences with the capability to recognize integrin receptors are analyzed. Conclusions: This review highlights the progress that has been made in the development of new nanocarriers, capable of responding to endogenous and exogenous stimuli essential to combat cancer

Analysis and Simulation of Small Signal Model of Virtual Synchronous Generator in Microgrid System

Microgrids based on distributed generation sources are connected to the main power grid through power electronic converters that have low mechanical inertia and damping, so the dynamic characteristics of the power system must be improved simultaneously with the integration of renewable energy sources for stability. Virtual synchronous generators are one of the effective methods for integrating renewable energy systems into the power grid. In order to have a behavior similar to that of a real synchronous generator when changed or disturbed by a virtual synchronous generator, the control operation is performed in the power electronic converter of the distributed generation unit. In this paper, the characteristics of two droop methods and a virtual synchronous generator for controlling active and reactive powers are compared using the small signal model and the state space model. The evaluation between these two different control strategies is performed using simulation results in the MATLAB environment. Also, the characteristics of the synchronous generator due to changes in the moment of inertia and damping coefficient are shown. Integrating the virtual synchronous generator in the microgrid, in addition to reducing frequency and voltage deviations, also improves stability.</p
