It seems likely, moreover, that with an increase in the rate of saving in mortgage lending institutions, interest rates on residential mortgages may move somewhat lower through the spring of next year, although the increased ease in residential mortgage lending may occur primarily in other terms than interest rate, e.g., easier downpayment and amortization terms.

However, in the Coulomb field of a nucleus the translational invariance is broken and single-photon annihilation may occur.

Interactions between alcohol and certain antibacterials may occur and may cause side-effects and decreased effectiveness of antibacterial therapy.

Cross-resistance to several antibacterials may also occur when a resistance mechanism encoded by a single gene conveys resistance to more than one antibacterial compound.

This may occur several times, until gamonts are produced, forming gametes that fuse to create new cysts.

As audio signals may be electronically represented in either digital or analog format, signal processing may occur in either domain.

These antidepressants typically have fewer adverse effects than the tricyclics or the MAOIs, although such effects as drowsiness, dry mouth, nervousness, anxiety, insomnia, decreased appetite, long-term weight gain and decreased ability to function sexually may occur.

Adhesion, the attachment between adhesive and substrate may occur either by mechanical means, in which the adhesive works its way into small pores of the substrate, or by one of several chemical mechanisms.

When subjected to loading, debonding may occur at different locations in the adhesive joint.

Although aluminium has a low gastrointestinal absorption, accumulation may occur mainly in the presence of renal insufficiency.

There is a risk of a benzodiazepine withdrawal and rebound syndrome after continuous usage for longer than two weeks, and tolerance and dependence may occur if patients stay under this treatment for longer.

This is simple enough, but several more points of interest may be mentioned as relevant.

Amadee may have owed this partly to his relationship with the king, but Othon, who at sixty seems still to have been a simple knight, merited his position solely by his own character and ability.

To those of my readers who find many of my opinions morally, or politically, or sociologically antiquated ( and I have reason to know that there are some such ), I would like to say what I have already hinted, namely, that some of my opinions may indeed be subject to some discount on the simple ground that I am no longer young and therefore incapable of being youthful of mind.

You may dress it up with any number of accessories or keep it as simple as you choose.

As shown earlier, the highly anxious individual may be superior in his memorizing of simple elements.

But his is still a simple life relatively free of the female presence or influence, and he must go far, even though he may go fast, for sophisticated pleasures.

Assistive technology devices can be simple, or " low-tech ", or they may use highly advanced technology, with some even using computers.

Assistive technology for sports may also be simple, or advanced.

Amateur astronomers also use star charts that, depending on experience and intentions, may range from simple planispheres through to detailed charts of very specific areas of the night sky.

The practical definition may lead to confusion with the definition of a coulomb ( i. e., 1 amp-second ), but in practical terms this means that measures of a constant current ( e. g., the nominal flow of charge per second through a simple circuit ) will be defined in amperes ( e. g., " a 20 mA circuit ") and the flow of charge through a circuit over a period of time will be defined in coulombs ( e. g., " a variable-current circuit that flows a total of 10 coulombs over 5 seconds ").

Most narrowly, one may consider numbers explicitly defined in terms of polynomials, exponentials, and logarithms – this does not include algebraic numbers, but does include some simple transcendental numbers such as e or log ( 2 ).

They may preside over a simple prayer service such as the Liturgy of the Hours which they are obliged to say with their community, speak about Scripture to their community, and give certain types of blessings not reserved to the clergy.

The latter resembles a sort of roll pastry whose main dough ingredient is either butter or fat and which may be simple or stuffed with dulce de leche, milk, jam, crema pastelera, or quince or apple jelly, among other fillings.

Level I, or associative learning, may be defined as retention of input and rote memorization of simple facts and skills.

Metal samples from large grained alloys may be simple to fabricate, particularly from wire samples, with hand-electropolishing techniques giving good results.

Intended for use in both training and daily activities like walking or performing chores, this simple measuring device may offer a solution for reducing obesity.

However, simple husbandry changes and practical midge control measures may help break the livestock infection cycle.

Although the butterfly effect may appear to be an esoteric and unlikely behavior, it is exhibited by very simple systems: for example, a ball placed at the crest of a hill may roll into any of several valleys depending on, among other things, slight differences in initial position.

In simple terms, trade deficits are paid for out of foreign exchange reserves, and may continue until such reserves are depleted.

Such computers are more versatile in that they do not need to have their hardware reconfigured for each new program, but can simply be reprogrammed with new in-memory instructions ; they also tend to be simpler to design, in that a relatively simple processor may keep state between successive computations to build up complex procedural results.

In simple craters, the original excavation cavity is overlain by a lens of collapse breccia, ejecta and melt rock, and a portion of the central crater floor may sometimes be flat.

Rough simulations of optical properties may be additionally employed: a simple calculation of the ray from the object to the point of view is made.

For I am not as simple as I may seem.
