The research was embarked upon to assess the variability in some physico-chemical properties of soil along a toposequence in Alvan Ikoku Federal College of Education, Owerri, Imo State. Soil samples were collected from two different depths, 0-15 cm and 15-30 cm, at each topographic unit, namely, upper slope, mid slope and bottom slope. A total of 12 samples were used for the study. The, samples collected were air-dried, crushed and sieved in a 2 mm sieve preparatory to...

For present investigation, total 100 surface and 40 profile samples were collected from five mango orchards of Ratnagiri District. An effort had been made to study the influence of soil depth on distribution of various physico-chemical properties. From the data, it could be concluded that the physico-chemical properties of soils of mango orchards characteristically represented typical lateritic soils in the ‘Very High Rainfall Laterite’ (VRL) zone in the Konkan region. For improvement of...

The food industry generates a large amount of wastes or by-products annually around the world from a variety of sources. By-products are the main raw materials for the formulation of functional foods in the food industry. Fruit and vegetable wastes are produced in large quantities in markets and their recovery could be employed for the production of nutraceuticals and functional foods. The food waste can be reduced by extraction of high-value components such as proteins, flavor compounds, and...

A DI Simpsons Tractor Diesel engine was investigated for performance and emissions with three different fuels namely Diesel, WCO (B100) and DWME (B20) blend. The fuel properties have been investigated with ASTM standard testing methods. It was noticed that, the pressure inside the cylinder are 90 bar, 89.29 bar, and 86.35 bar respectively, for Diesel, B100 and B20. Further, it was noticed that B20 blend leads to increase the NOx in exhaust gas.

Abstract — Improving peat soil is difficult but not impossible. Managed correctly, peat can be a highly productive medium for agriculture, but drainage and cultivation can lead to irreversible peat shrinkage. Vegetational changes during the restoration of cutover peatlands leave a legacy in terms of the organic matter quality of the newly formed peat. Current efforts to restore peatlands at a large scale therefore require low cost and high throughput techniques to monitor the evolution of...

The NIST research focuses on measurement of major thermophysical and chemical properties of JP-8, to develop it as a reference fluid. The properties include fluid volatility, density, speed of sound, viscosity and thermal conductivity. In addition, we are assessing the global thermal decomposition of the fluid, primarily to guide our property measurements. The measured properties will be used to develop a predictive surrogate fluid model for real JP-8. Three different samples of JP-8 have been...

A special class of decentralized control problem is discussed in which the objectives of the control agents are to steer the state of the system to desired levels. Each agent is concerned about certain aspects of the state of the entire system. The state and control equations are given for linear time-invariant systems. Stability and coordination, and the optimization of decentralized control are analyzed, and the information structure design is presented.

Recent needs in the non-aerospace industrial sector have revitalized interest in high performance alloys. TAZ-8A has a combination of properties that makes it unique: a high temperature strength, oxidation resistance, abrasion resistance, and exceptional thermal shock resistance. The major drawback for the utilization of this alloy is the relatively high cost compared with the more common iron base alloys. Reduced material consumption and lower costs are possible by using coatings of TAZ-8A on...

A new hybrid surface-integral-finite-element numerical scheme has been developed to model a three-dimensional crack propagating through a thin, multi-layered coating. The finite element method was used to model the physical state of the coating (far field), and the surface integral method was used to model the fatigue crack growth. The two formulations are coupled through the need to satisfy boundary conditions on the crack surface and the external boundary. The coupling is sufficiently weak...
