EOR method evaluation is performing for petroleum gravity, stone type, and tank humectant and tank localities conditions for liquid injection. When the water inject to the tank the interaction could be performed in different ways, if the is humectant, penetrated water canexit petroleum from tank, which is because of capillary absorption. The studies have been done on the tube lines, land and the metal workforces that are related to the oil and gas industries, shows that in most cases, weld lines and edge of a sharp regions has been influencing on location of corrosion and eroding of effective thickness of coating film. In this study we studied EOR methods for dense oil recovery from mold in the breakage tanks. Analyze and comparison of recovery with capillarity of salty water, polymeric solution and hot water on different sample of rocks showed high recovery of dense row oil in the EOR methods, and it is more detected in the diluted row oil. Oil (diluted) can recover by water injection in the sand stone condition and with chemical matter and thermal methods.

The benefits of risk management in projects are huge. You can gain a lot of money if you deal with uncertain project events in a proactive manner. The result will be that you minimize the impact of project threats and seize the opportunities that occur. This allows you to deliver your project on time, on budget and with the quality results your project sponsor demands. Also your team members will be much happier if they do not enter a "firefighting" mode needed to repair the failures that could have been prevented. In this paper we identified six common risk factors that could impact a project. Some factors are obvious, but some are not and it is important to identify them all. You are encouraged to review them all when planning for project risks. Also In this paper we describe common schedule risk factors. We give you some tools to identify risk and lower its impact, thereby saving your projects from schedule slips.

The importance of project management has become more and more significant today especially in today's market situation. The current economy and downturn as well as highly competitive market have made our market changed totally. For his reason in this paper about the effect of different factor to project successes has discussed. And the advantage and disadvantage of each factor has shown.

In order to manufacture any product at desired quality of machining, optimum parameters are to be selected for machining. The aim of the present work is to optimization of the process parameters (Cutting Speed, Feed, Depth of cut) for machining the Bearing cap having interrupted cuts. Computer Aided Mass Balancing (CAMB) methodology is used for determining the counterweight for rotary fixture. The performance characteristics are studied by using the orthogonal array, signal-to-noise ratio, and the ANOVA from Taguchi method for interrupted cuts of boring operation and effect of Cutting force for balanced and unbalanced rotary fixture.

This paper will deal with the developed wing for the Flying Bike in order to provide the maximum lift in a short takeoff and also to maintain the coefficient of lift for smooth landing, for this the development is carried out with the NACA 4 Digit Airfoil series concept on considering Flat Bottom Airfoil as already in use for sail planes and A-18 Airfoil for Small wind turbines, which have significant results on various models of airfoil but the appropriate one is to be chosen among the symmetrical and flat bottomed airfoil for the best flying concept with minimum drag and maximum speed in air. Also we find airfoil everywhere like in wings, tail surfaces (vertical fin and horizontal stabilizer), Propellers and turbofans, helicopters rotors, compressors and turbines, wind turbines, hydrofoils wing like devices which can lift the water boat above water.

The thermal power plants are used to generate power. The thermal power plants are designed based on required conditions, but actually inlet conditions are not as per the designed conditions. Variations in the power outputs from power plant are always a matter of disputes. So correction curves for power and heat rate are generated. In this paper, the thermodynamic analysis of 120MW thermal power plant has been done at a different inlet pressure (123.14 bar) and at different inlet temperatures (507.78°C, 517.78°C, 527.78°C, 537.78°C, 547.78°C, 557.78°C, 567.78°C). The correction curves for power and heat rate have been generated for the combined effect of inlet pressure and different inlet temperatures. These curves indicate that if inlet conditions vary then power output and heat rate also vary.

The thermal power plants are designed based on required conditions (like quality of steam, pressure and temperature of steam e.t.c.), but actually inlet conditions are not as per the design conditions. In practical situations, when power plants are installed there are lots of constraints. This tends to reduce or increase output power and heat rate of thermal power plants. These constraints are leakages, installation errors etc. So due to these conditions, the designed power and heat rate are never achieved. Due to these variations in the power output from plants, it is always a matter of disputes. So the correction curves for power and heat rate are generated for pressure drop in extraction line 5, as a parameter at different conditions. These curves indicate that if operating conditions are vary, then power output and heat rate also vary. This paper deals with the generation of the correction curves for 120 MW thermal power plant by using computer aided software for pressure drop in extraction line 5.

The concept of paper begin with a review of the salient theory and available body of literature of SCM in terms of responsibility, manufacturing practices, competitive advantages, SCM practices and overall performance of company. As the study composed of surveys of 92 manufacturing companies nearby Bhopal and in-depth interviews is discussed and their findings shared. Various statistical tools are used for the analysis of collected data. Their reliability and content are checked using reliability analysis. The discussion of findings and their implications, and concluded with some suggestions for future research.

Visco- Elastic Plates are being increasingly used in the aeronautical and aerospace industry as well as in other fields of modern technology. To use them a good understanding of their structural and dynamical behavior is needed. In the modern technology, the plates of variable thickness are widely used in engineering applications. The present work is to develop for the use of research workers in space technology, mechanical sciences and nuclear energy where certain components of the structure have to operate under the elevated temperature. The aim of present paper is to study the bi-linearly thermal effect on vibration of visco-elastic square plate whose thickness varies parabolically in x-direction. A frequency equation is derived by using Rayleigh-Ritz technique. Two modes of frequency are calculated by the latest computational software for the various values of taper parameter and thermal gradient.

Instrumented cadaveric knees were used to address the interaction between unopposed quadriceps muscle forces (QMF), ground reaction force (GRF), and strain in anterior cruciate ligament (ACL) through in-vitro simulation of a vertical jump-landing process. The objective of this research was to evaluate the effect of unopposed QMF, low knee flexion angle, joint conformity and constant GRF on the ACL strain. Fourteen cadaveric knees were mounted in a custom made dynamic loading simulator. The strain on the anteromedial bundle of the ACL was measured using a Differential Variable Reluctance Transducers (DVRT) sensor. Also, an I-Scan pressure transducer was used to measure the contact pressure and area in the tibiofemoral joint. During landing phase, the peak pressure on the lateral compartment is very high compared with the medial compartment. During landing phase, both the contact area and pressure increases in the tibiofemoral joint. The induced joint conformity caused by contact pressure has been justified. The results show that unopposed quadriceps muscle forces coupled with ground reaction force at low knee flexion angle cannot cause ACL injury. Joint compressive loads induced by large muscle forces and GRF introduces the joint conformity, and it produces the primary restraint against anterior tibial translation at low flexion angles.
