Soil mechanics

The present paper also includes strength prediction models that consider the influence of curing temperature. In addition, the Thermogravimetry analysis (TGA) used to determine the chemically bound water content in cement-treated soil and the X-ray diffraction (XRD) test to explain the chemical mechanism in cement-treated soil are also mentioned.

The study focuses on answering the question of how to precisely define the high runoff areas in order to propose a suitable soil and water conservation practices and explicit placement of agricultural BMPs. In order to answer the research question, the analogy of combination SCS–CN and STI was proposed.

Pesticides (mainly herbicides, insecticides, and fungicides) are used to chemically combat certain plants, animals, or microorganisms perceived as harmful to agriculture. Due to the fundamental similarities in all living beings, it is challenging to target unwanted species without affecting others, including humans.

Unsaturated soil behaviors characterize the failure mechanisms of geotechnical infrastructures with transient seepage conditions. Therefore, an accurate estimate of the unsaturated groundwater flow is vital in improving hazard management and assessment. This study attempts to develop a numerical scheme for 2-D transient analysis under unsaturated conditions.

The primary objective of this research is to develop an ML-PTF on the extreme gradient boosting (XGB) framework capable of estimating soil compression index with high precision and low effort. Furthermore, advancing the quantitative knowledge of which soil structural indicators determine soil compressibility using correlation analysis.

The study was carried out during 2013-14 in Meerut district of Uttar Pradesh state to focus on the sugarcane growers regarding impact of knowledge on adoption level of IPM practices. The 80 contact farmers were selected as respondents. The study revealed that the maximum knowledge gap was found to be existing in previous crop residues, crop rotation, hand picking of the insect and their destruction, hot air and water treatment, light and pheromone trap, microbial control, use of natural enemies, resistant varieties, biopesticides/ bio-agents, application and dose of different pest etc.

The technological conditions of obtaining the polylactic acid-Vietnamese cassava starch blend on the mix-brabender were investigated. The optimal conditions were: temperature 160o C, reaction time 6 minutes, screw speed 45 r/min., initial material ratio in weight percentage PLA80- PEG10-TB20. Polyethyleneglycol (PEG) as a plasticizer, PN-47 as a distribution agent was used. It showed that the optimal starch content was 20 wt%. Increase in starch content lead to increase in water absorbability and weight loss of the materials.
