Communicate! Communicate! Communicate!
Published in M. Ann Garrison Darrin, Patrick A. Stadter, Aerospace Project Management Handbook, 2017
As a general topic of communication, project norms should be established for use of e-mail. These should include common practices such as honoring the “chain of command” by adding personnel in the CC list of an e-mail who are intermediate in the management chain between the sender and the recipient. Also, it is good practice to include personnel in the CC list who are named in the body of the e-mail. Sensitive information would be an exception to this convention. Responders to e-mail should be thoughtful of the “reply all” button and only use it if everyone should be aware of the response. Like all communication, e-mail CC lists should include stakeholders appropriate to the level of information being transmitted. That is a subjective decision, but when the sender takes the time to simply consider this, communication is likely to become more effective.

Attar et al. (2013) analyse the magnetic effect on fuel by conducting experiments using permanent magnets of different intensities viz. 2000, 4000 and 6000 Gauss on 4- stroke Petrol Engine (Two Wheeler).The current research emphasis on the impact of permanent magnets on fuel consumptions. Table shows the effect of magnetic field on kilometre run of bike for 1000 ml of fuel consumption (Table 11). Engine specification:a. Type: 1 Cylinder 4- Stroke petrol Engineb. Cooling- air cooledc. Power- 15.4 PSd. Engine Displacement (CC)- 159.7e. Torque- 13.1 NmDue to a magnetisation of fuel, improves the atomisation of the fuel, better mixing ensuring complete combustion or no loss of energy.

In the case of without confinement, the compressive strength variation between cubes strength and cylinders strengths are traditional. The cube compressive strength of mix CSCQ at 28 days is comparable with CSC, CC and CCQ. Compressive strength of CSCQ mix is increased by 7.42% compared with CSC mix. Similarly, compressive strength of CCQ mix is increased by 8.36% compared with CC mix. Cubes and cylinders compressive strength of CC, CCQ, CSC and CSCQ without confinement are presented in Tables 5 and 6, respectively. Compared to river sand, quarry dust has finer particle. It is assumed that this presence of finer particles leads to closer packing between the coarse aggregates and in turn leads to comparatively more density of concrete. This may be the reason for the strength enhancement of concrete while quarry dust is used in place of conventional sand. However, the presence of finer particles of quarry dust also leads to reduction of workability of concrete compared to sand used in concrete production.

The experiments were conducted on a single cylinder, four stroke, water-cooled direct injection diesel engine. The engine displacement was 661 cc, and rated power of the engine was 4.4 kW. Load can be applied on to the engine by means of an eddy current dynamometer. The specifications of the diesel engine are shown in Table 3. The in-cylinder pressure sensor was connected to the piezoelectric transducer. A charge amplifier was used for the pressure sensor and for analysing the combustion pressure. The crank angle position was measured by using a magnetic rotary encoder installed on the engine crankshaft. The cylinder pressure and heat release rate data were recorded and determined by using a data acquisition system. The measuring instruments used in the diesel engine are given in Table 4. An AVL-735 fuel mass flow meter was employed for measuring fuel consumption. An AVL DI GAS 444 N gas analyzer was employed to measure CO, CO2, HC and NOx emissions. Measuring ranges of AVL DI GAS 444 N gas analyzer are given in Table 5. An AVL Smoke Meter 437C was used to measure the smoke opacity. The performance, combustion and emission characteristics of a diesel engine were studied by using B20, B20MWCNT40 fuel samples with and without EGR at a constant speed of 1500 rpm and at five different load conditions (0%, 25%, 50%, 75% and 100%). The experimental set-up is shown in Figure 5. An orifice meter was used to measure the flow rate of the exhaust gas in the diesel engine. The 20% EGR rate was adjusted by using an EGR valve which is arranged at the air inlet passage in a diesel engine.
