  • This paper presents in situ tests which were performed on both single piles and pile groups, loaded to failure, with the aim of studying the pile group effect of piles embedded in multi-layered foundation. Strain gauges were installed along the shaft of 10 m long steel pipe piles, with a diameter of 143 mm. The influence of loose sand layers on the group effect in case of friction piles was evaluated. The experimental results indicated that the influence of sand layers was evident, and the group factor was calculated to be 1.237.

  • In this paper, a model is presented for predicting the transport of an environmental pollutant from the source to and through the soil. The model can predict the deposition of an environmental pollutant on the soil surface due to the pollutant being loaded on dust particles, which are later deposited on the soil surface.

  • Vertical distribution of DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) and its correlation with several physico-chemical properties of soils in fifteen orange orchards of Tamenglong district, Manipur was studied. Most of the upper soil layer had higher DTPA-extractable micronutrient cations (Fe, Cu, Mn and Zn) content than the lower horizons. In the profiles, the value of DTPA- extractable micronutrients (Fe, Cu, Mn and Zn) ranged from 18.62 to 45.12 mg kg-1 , 0.12 to 1.26 mg kg-1 , 3.42 to 44.33 mg kg-1 and 0.16 to 1.36 mg kg-1 , respectively.

  • Đất là loại vật liệu tự nhiên có khả năng lọc, hấp phụ các chất ô nhiễm. Do đó sử dụng vật liệu có nguồn gốc từ đất sẽ có khả năng xử lý nước thải và làm sạch môi trường. Nghiên cứu đã thực hiện đánh giá khả năng xử lý nước thải sinh hoạt tại nguồn phân tán bằng kỹ thuật phối trộn các tầng vật liệu có nguồn gốc từ đất (Multiple soil layering/MSL).

  • The first important question is “What is a Web application”? Although most people have an intuitive notion of what comprises a Web-enabled application, rarely do we think about its scope and complexity. Web applications are typically multi-layered entities that include code and data residing in many places within the enterprise (see Figure 1) that can be accessed directly or indirectly from the Internet. Some parts of the application are typically developed in house are unique to the enterprise while others are purchased from an external vendor (e.g.

  • Spices like black pepper, cardamom, tree spices such nutmeg, cinnamon, clove are perennials and ginger and turmeric are grown annually. Most of them are propagated by vegetative methods. Non- availability of quality planting material is one of the important production constraints that affect the area expansion or gap filling programmes. Each crop requires specific techniques and handling to produces for planting material production from proven mother plants. The black pepper cuttings collected from mother plant are further multiplied by employing suitable rapid multiplication techniques.
