One of the most valid and efficient models of long rod projectile penetration in homogeneous targets is Tate and Alekseevskii’s (A&t) model. Based on Tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. The proposed collision speed-penetration depth diagrams are developed using Tate’s model. In this way, va...

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...

Abstract The foundation is the part of a building that rests on ground. net safe bearing capacity ( q ns ) significant factor in design. There are several ways published previous studies to determine capacity, however choosing best method governs stability structure when it loaded beyond its capacity. emphasis this concern investigated and presented paper by comparing shallow foundations determ...

Agriculture land shows soil compaction problems due to long-term agricultural cultivation activities. Soil indicator can be seen from the value of penetration resistance at different depths (0 - 60 cm). This research aimed determine coffee plantation ages with and analyze relationship between physical characteristics productivity. The survey activities include observation minipits, measuring 0-...

In-situ soil assessment such as field compaction can often be a helpful approach in help determining suitability for certain crops. In this study, an was conducted to characterize the Soil Penetration Resistance (SPR) planted sago palm (Metroxylon spp.) plantation at different growth of rosette and trunking stages under mineral soils ecosystem. SPR in-situ would provide beneficial guideline sit...

There is little empirical evidence to indicate that dairy cow live weight affects the extent of soil damage at the hoof-soil interface during grazing on poorly drained permanent grassland. In the present study the impact of Holstein-Friesian (HF) dairy cows with a mean (±standard deviation) live weight of 570 (±61) kg were compared with Jersey × Holstein-Friesian (JX) with a mean live weight of...
