This relatively widespread use of VBScript is not because of many special merits of VBScript-several useful features of the full Visual Basic, such as strong typing, extended error trapping and the ability to pass a variable number of parameters to a subroutine have been removed-but mainly because, apart from being easy to learn, royalties need not be paid to Microsoft by implementers as long as the VBScript trade mark is acknowledged.

The maximum possible range, typically beyond 7, 000 yards, was beyond useful shrapnel combat ranges for normal field guns due to loss of accuracy and the fact that at extreme range the projectiles descended relatively steeply and hence the " cone " of bullets covered a relatively small area.

Its combination of low raw material cost, relatively simple processing, and a useful temperature range make it currently the best compromise among the various competing materials.

This unit is useful because it scales with clock frequency and thus allows relatively slow interconnects such as T1 to be compared to higher-speed internet backbone links such as OC-192.

In making useful applications of technology to domains such as healthcare, it is helpful to discriminate between problems which are very, very hard ( such as deep understanding of pathophysiology as it relates to genetic and various environmental influences ) and problem which are relatively easier, such as following the status of negotiations between a patient and a health care provider.

Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it requires significant operator skill and can only be accomplished at relatively low speeds.

11, 982 is inherently difficult due to the large number of aces and other small cards high in the stack, as well as the high cards being relatively evenly distributed among the stacks, requiring one to use many of the cells to get to any useful cards.

At the scale where humans exist and interact with the universe, Newtonian mechanics remain useful, and make relatively accurate predictions ( e. g. calculating the trajectory of a bullet ).

Even a queueing model based on the Poisson process that does a relatively poor job of mimicking detailed system performance can be useful.

A useful feature of C. elegans is a relatively straightforward method to disrupt the function of specific genes by RNA interference ( RNAi ).

It has the same food energy as proteins, but because it is so intensely sweet, relatively little of it is needed to sweeten a food product, and is thus useful for reducing the number of calories in a product.

Using sensors and pumps, a relatively small amount of energy ( i. e. that used to power a pump and controller ) can harvest a far larger amount of available thermal energy by switching on as soon as a useful temperature differential becomes present.

It is resistant to corrosion, the case head can be drawn and work hardened to make useful cases for modern metallic cartridges working at relatively high pressure, and the neck and body portion are easily annealed to make the case ductile enough to allow reforming so that it can be reloaded many times.

It is this relatively high energy which makes gamma rays useful in radiography but potentially hazardous to living organisms.

Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, providing useful clues to the human past, including prehistoric trade.

Most people prefer to engage with programs that are human-like, and this gives chatbot-style techniques a potentially useful role in interactive systems that need to elicit information from users, as long as that information is relatively straightforward and falls into predictable categories.

Because diabatic processes, which can change PV and entropy, occur relatively slowly in the atmosphere, PV is useful as an approximate tracer of air masses over the timescale of a few days, particularly when viewed on levels of constant entropy.

Critics have objected to GMOs on several grounds, including tampering with nature, ecological concerns, economic concerns raised by the fact these organisms are often subject to intellectual property law, whether food produced from GMOs should be banned or labelled, whether such food is safe, and whether GM crops are useful to address the world's food needs.

Both these methods are useful as they are either cheaper or free, effective, safe and feature low thermal inertia transfer methods, meaning the chemist does not have to wait for a bath to cool down after use.

In cases where the individual cannot be kept safe, hospitalization may be useful, though the value of this practice for individuals not mentally ill is disputed by proponents of investigative or recreational use of psychoactive compounds.

In July, 1837, the Society reported that " the conclusion to which we have been led by this course of enquiry is that the establishment of a medical School for the education of the Indians of the presidency in Medical Science, to the extent of qualifying Indians to become useful and safe practitioners of medicine.

To identify the minimum safe hematocrit desirable for a given patient the following equation is useful:

TraficOK is really useful to drivers, providing them with warnings and alternative routes when problems on the planned itinerary are spotted, based on the safe alternative routes calculated by the application to avoid the traffic events.

Students of both fields learn to design comfortable, safe, and useful indoor spaces, from downtown penthouses to high school classrooms.

On Oddworld: Abe's Exoddus, the quicksave function is accessible at any time during play through the pause menu and is useful to use it in safe spots so that in the occasion that you die in the next dangerous part of a level it is not necessary to repeat a relatively long section of playing to try it again, however, because it's possible to quick save when you are cornered or otherwise bound to lose, and because you can't quick save on more than one location some strategy is needed to know when it is useful and safe to quick save.

It is also the period when the majority of mine reclamation is completed, making the land safe and useful again.

Subsequently, the bridge was deemed safe for the time being, but would need substantial repairs and retrofitting in order to ensure motorist safety, and to extend its useful service life if replacement was found not to be a viable option in the near future.

* Offer customers personal service and useful safe, quality products

His obituary noted that " his taste was a little theatrical, and his talent not good enough to redeem it ... it is safe to say that he will be best remembered, not by them, but by his good work at the Academy Schools and by his administrative services to the body of which he was a useful member ... the exacting taste of the present day asks for something less conventional than his rather superficial battle scenes.

A dinghy is useful to avoid the need for expensive dock or slip space, so owners of small yachts compromise by carrying a small rigid dinghy or deflated inflatable, or by towing a larger dinghy.

Criteria with regards to hemodynamic compromise or respiratory failure are not useful clinically because these symptoms often do not arise in neonates until death is imminent and unpreventable.

This is a typical example of contradicting requirements where the filter design process may try to find a useful compromise.

Such compromise editions are particularly useful for early music, where the interpretation of the musical notation of long ago often poses difficulties.

Such control is particularly useful in cornering, to avoid unwanted upshifts or downshifts that could compromise the vehicle's balance or traction.

Interlaced video has been a useful compromise for decades due to its ability to display motion smoothly while reducing recording and transmission bandwidth.

Instead the Quasi-Delay-Insensitive model is the smallest compromise model yet capable of generating useful computing circuits.
