Productivity of the groundnut grown under the optimum water availability was 113.7 g dry podsplant this was 21.5 g 23.3 higher than that of the plant grown under the suboptimum soil moisture condition. This result was due more to higher seed yield rather than to bigger seed size and seedpod weight ratio.

Sep 20, 2017 Optimization of cutting operations in quarrying and processing of building stones leads to certain reductions in operational costs. Despite the developments of cutting technology and employment of more efficient cutting machines, there is still a need to optimize a series of operational parameters the cutting direction is one of them. In order to optimize the cutting direction parameter in ...
A quarry is an excavation or pit, usually open to the air from which quarry resources are obtained, usually rocks found on or below the ground surface. Quarry plays a big role in the construction industry. Some form of quarrying is carried out in
Optimum fragmentation of rocks during blasting is pivotal for the productivity of mining and civil engineering systems. Extensive studies on the ubiquitous fragmentation phenomena in nature and artificial processes have attested to the dominant control of the effective dimensionality and material brittleness on the size distribution of fragments.

In most cases, the productivity rate is influenced by the degree of fragmentation. To obtain well-fragmented rock by blasting, explosive energy must be well distributed throughout the rock. To be effective in rock blasting, this energy must be applied at the proper millisecond delay interval to allow for optimum rock movement.
