Africa is the second continent suffering from soil compaction; studies of this phenomenon must be multiplied in order to overcome problem. Very few have been conducted Tunisia understand compaction, its causes and effect on properties. The research was experimental field at Higher Institute Agronomy Chott Mariam, Sousse, Tunisia. main objective study evaluate different speed tractor compaction ...
Particle breakage during compaction affects behavior and the quality of formed compact. This work conducted a numerical study based on discrete element method (DEM) to investigate effect particle dynamics compact properties, including size density distributions, pore properties. A force-based criterion Apollonian sphere packing algorithm were employed characterize behavior. The structures compa...
fly ash is one of the most plentiful and versatile of the industrial by-products. at present, nearly 150 million tonnes of fly ash is being generated annually in india posing dual problem of environmental pollution and difficulty in disposal. this calls for establishing strategies to use the same effectively and efficiently. however, it is only in geotechnical engineering applications such as t...
Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. Many of the traditional anti-corrosion approaches such as the chromate process are effective but hazardous to the environment and human health. Mefp-1, a protein derived from blu...
the use of heavy machinery in forestry operations such as logging has increased worldwide during the last decades. however, these machines may seriously influence the soil ecosystem as they induce rutting, disturbing the upper soil layers, and soil compaction. severe compaction of soil adversely affects the growth of plants.this study was done by using a penetration resistance experiment in a g...
Mechanistic details of DNA compaction is essential blue print for gene regulation in living organisms.Many in vitro studies have been implemented using several compaction agents. However, these compacting agents may have some kinds of cytotoxic effects to the cells. To minimize this aspect, several research works had been performed, but people have never focused green solvent, i.e. room tempera...
Increased soil compaction resulting from livestock treading and use of heavy machinery is a major environmental hazard often linked to degradation the ecosystem economic services. However, there weak quantitative understanding spatial temporal extent how it modifies properties associated functions. To address this challenge, we developed framework for systematic modelling caused by grazing anim...
During eukaryotic evolution, genome size has increased disproportionately to nuclear volume, necessitating greater degrees of chromatin compaction in higher eukaryotes, which have evolved several mechanisms for genome compaction. However, it is unknown whether histones themselves have evolved to regulate chromatin compaction. Analysis of histone sequences from 160 eukaryotes revealed that the H...
A software for soil compaction analysis (SCAN) has been developed for evaluating the compaction states using the data from the GPS as well as a compactometer attached on the roller. The SCAN is distinguished from other previous software for intelligent compaction (IC) in that it can use the results from various types of GPS positioning methods, and it also has an optimal structure for remotely ...
