Introduction We have all heard the old joke of school being all about the three “R’s”, Reading ‘Ritin and ‘Rithmatik, but because of increasing class sizes and reported lack of instruction time, writing has been passed over for the more “important” subjects. The advent of computers and the increasing ease of word processing have given teachers the ultimate excuse, but most beginning composition...

Row hammer attacks exploit electrical interactions between neighboring memory cells in high-density dynamic random-access memory (DRAM) to induce memory errors. By rapidly and repeatedly accessing DRAMs with specific patterns, an adversary with limited privilege on the target machine may trigger bit flips in memory regions that he has no permission to access directly. In this paper, we explore ...

The chert gravels are a by-product of sand mining in the south Israel; reserves amount to tens millions tons and continue grow. attempts their comminution for production aggregates by conventional mechanical methods have not yet been successful due high abrasiveness, as well flaky form fracturing. This study was motivated need find an alternative method rock that would ensure aggregate line wit...

In the construction industry, non-destructive testing (NDT) methods are gaining more popularity for their ability to examine the in-situ component properties without damaging the structure. One of the most common NDTs for measuring the concrete compressive strength on site is the Rebound Hammer Test. Using the rebound value obtained from the test hammer, the concrete compressive strength can be...

Abstract The slope instability was one of the common problems along road that connects Gutane Migiru town to Fincha sugar factory, Western Ethiopia. effect problem intense mostly; during rainy season, triggers different modes rock failure. As a result, frequently damaged and blocked by failed in turn hinders traffic activities. Thus, this study aimed at stability analyses critical sections usin...

Introduction: This study aims to determine the amount of hand-arm vibration transmitted from heavy electric destruction tools and the effect of using chisel with different lengths and shapes when demolishing concrete surfaces. Material and Methods: To evaluate the magnitude of hand-arm vibration on the left and right handles of two powerful electric demolition hammers commonly applied in Irani...
