In this way,to take one example,the stereocenters
in the terpenoid side chain of tocopherols
could be introduced stereoselectively (Fig.
3),providing an attractive route to these biologically
and economically important fat-soluble
antioxidants,which are the main components of
vitamin E.Despite considerable effort in various
laboratories,no commercially viable stereoselective
total synthesis of (RRR)-tocopherols has
been developed so far (25).

寻求高手汽车专业英语翻译 Bleeding a Power Steering System
Any time you replace or repair a hydraulic component (pump. hoses, and power piston ), you should bleed the system. Bleeding the system assures that all of the air is out of the hoses, the pump, and the gearbox. Air can cause the power steering system to make a BUZZING
sound. The sound will occur as the steering wheel is turned right or left.
To bleed out any air, start the engine and turn the steering wheel fully from side to side. Keep checking the fluid and add as needed. This will force the air into the reservoir and out of the system.

With rear-motor drive, a further distinction is made between rear-engine and mid-enginedesign depending on the position of the engine relative to the axle.
Transaxle design: The term transaxle is a general term for transmission + axle,
referring to a combined transmission and axle drive unit. The concept accordingly applies to front-wheel drive as well as to transmissions with the final drive mounted at the rear axle. The term as used in Germany is more closely circumscribed, and relates only to the. This incongruity of terms between German and English often leads to misunderstandings.

A convenient choice of voltages for many networks is the set of node voltages.Since a voltage is defind as existing between two nodes,it is convenient to select one node in the network to be a reference node or datum node and then associate a voltage or a potential with each of the other nodes.The voltage of each of the non-reference nodes with respect to the reference node is defined to be a node voltage.It is common practice to select polarities so that the node voltages are positive relative to the reference node.For a circuit containing N nodes,there will be N-1 node voltages,some of which may be known,of course,if voltage sources are present.

The return on capital employed would 15%, 14.63% and 14.81%respectively.
This debate will become more important to you when you approach your Third
LEVEL Accounting studies. For Second Level, it is enough to say that it is usual to calculate the profit made during a year as a percentage of the capital employed at the end that year. In this example, then, the usual answer would be 14.63%.
Measuring the return on capital employed is more difficult where the businessman
Not only user his own money but borrows money as well. To illustrate the effect of this, suppose that as well as his own capital, Solly has a loan form his bank amounting to €18,000.He borrowed this at the beginning of Year 7,and will repay it at the end of Year 11. It carries a fixed interest rate of 9%.How does this affect the calculation of the return on capital employed?

Polarization is most important if you are trying to get the maximum performance from the antennas. For best performance you will need to match up the polarization of the transmitting antenna and the receiving antenna. When a signal is transmitted at one polarization but received at a different polarization there exist a great many decibels of loss.

Readily accessible 2-isocyanobiphenyls react with aromatic aldehydes via base promoted homolytic aromatic substitution (BHAS) to give 6-aroylated phenanthridines. Reactions occur via addition of acyl radicals to the isonitrile functionality and subsequent intramolecular BHAS of the intermediate imidoyl radicals. Initiation of the radical chain reaction is best achieved with small amounts of FeCl3(0.4 mol %), and the commercially available and cheap tBuOOH is used as the oxidant.

Loadings in buildings consist of the combined dead and imposed loads which exert a downward pressure upon the soil on which the structure is founded and this in turn promotes a
reactive force in the form of an upward pressure from the soil. The structure is in effect
sandwiched between these opposite pressures and the design of the building must be able to resist
the resultant stresses set up within the structural members and the general building fabric. The
supporting subsoil must be able to develop sufficient reactive force to give stability to the
structure to prevent failure due to unequal settlement and to prevent failure of the subsoil due to
shear. To enable a designer to select, design and detail a suitable foundation he (she) must have
adequate data regarding the nature of the soil on which the structure will be founded and this is
normally obtained from a planned soil investigation programmer.

What do Leonardo da Vinci. Paul McCartney. Napoleon. and John McEnroe have in common? They are all left-handed. Today, about 15 percent of the population arc if handed. But why are peopleleft handed? The answer is the way the brain works. The brain has two halves-the right half and the left hail. The right half controls the left side of the body, and the left controls the right side of the body. So right-handed people have a strong left brain, and left-handed people have a strong right brain. The two halves the brain are about the same size. But each side controls different things. The left side controls language, math and logic. When you memorize the spelling of words, or when you put things in order, you use your left side. The right side of the brain controls you love of art, color and music, It is also good at recognizing faces. This does not mean, that all artists are left-landed and accountants (会计) arc right handed. There arc many exceptions (例外). Some right-handers have a strong right- brain, and some left brain have astrong left brain.
