Subsidence is an inevitable consequence of mining, however the effects of subsidence depend on the type of deposit, the geological conditions, in particular the nature and structure of the overlying rocks or soils, the mining method and any mitigative action Unfortunately, subsidence can have serious effects on surface structures, buildings, services and communications, and can damage agricultural land through the disruption of drainage and alteration of gradient.
Completely different meanings even occur in different branches of physiology, e. As a student, it is easy to despair! But the meanings of words are very precise in science: This glossary is for browsing in, testing yourself, and learning about words that catch your eye.
Stop and read wherever you may have doubts or interest. Also of course it is a place to look up words you come across and don't understand. But it is very selective. You need both an English dictionary and a scientific or medical dictionary too. Many words that you think you understand OK, you may find aren't used quite how you thought!
This glossary concentrates on words that often cause confusion, especially in the basic sciences physics, chemistry and mathematics that are the foundation of physiology.
You don't need to understand everything, but the more you understand, the easier it will be to learn more. You are often expected in exams to explain the meanings of words: Click or email to a. It is usually simpler and clearer to say 'horizontal axis', since most people have to stop to think which axis 'abscissa' means.
As an aid to memory: Note that all parts of a rotating object are accelerating except on the axiseven if the rotation is steady: Acceleration is detected in man largely by the labyrinths.
Acclimation is sometimes used specifically to mean adaptation to a single changed factor as under laboratory conditions. Used in several senses: Attenuation or absence of a response when a stimulus is applied slowly e.
NB this is distinct from adaptation, but is often seen in the same systems. Adjustment of focus of the eye. Cumulative toxins are ones that are absorbed but not excreted, for which it is the total dose over a prolonged period that matters rather than the level of exposure at any one time.
Accuracy is limited firstly by the ability of a measuring system to distinguish different conditions resolution and secondly by its ability to relate the conditions correctly to a standard calibration. The two considerations must not be confused. A high resolution instrument giving stable readings and sensitive to small changes may nevertheless be completely inaccurate if not adequately calibrated.
Accuracy cannot usually be greater than the resolution of a measurement, except in special circumstances e. An acidotic condition may be capable of being restored to normal acid-base balance by increasing respiratory ventilation to reduce the CO2 content of the body respiratory acidosisor it may require retention or injection of HCO3- metabolic acidosis.
Disturbances are lessened in the short term by numerous pH buffer systems. Influences affecting blood pH are altered absorption, metabolism and respiration, and disturbances affecting the control systems.
Action potentials occur spontaneously or as all-or-none or frequency coded reactions to stimulation. Sodium spikes are brief ca. A compound action potential is an extracellular recording of the combined effect of action potentials in many cells. A catalyst reduces the activation energy.
This requires energy, and can occur by linkage of carrier mediated transport to a process providing energy, such as the hydrolysis of ATP or the downhill movement of another substance.THE LANGUAGE OF FANDOM.
Like a lot of subcultures, fandom members speak their own vernacular that can sound utterly impenetrable to outsiders.
|Determining Sites of Unsaturation||Thus, to minimize the effect of the force on an object involved in a collision, the time must be increased. And to maximize the effect of the force on an object involved in a collision, the time must be decreased.|
|Cheat Sheet||Because practitioners of the statistical analysis often address particular applied decision problems, methods developments is consequently motivated by the search to a better decision making under uncertainties.|

|Strategies||Comparing the values in rows 1 and 2, it can be seen that a doubling of the net force results in a doubling of the acceleration if mass is held constant. Similarly, comparing the values in rows 2 and 4 demonstrates that a halving of the net force results in a halving of the acceleration if mass is held constant.|
The purpose of this page is to provide resources in the rapidly growing area of computer-based statistical data analysis. This site provides a web-enhanced course on various topics in statistical data analysis, including SPSS and SAS program listings and introductory routines.
Topics include questionnaire design and survey sampling, forecasting techniques, computational tools and demonstrations. Introduction. In this lesson you will learn how to write equations of quantities which vary inversely.
Graphs of inverse relationships will be modified to show a linear relationship.; Definitions. Quantities vary inversely if they are related by the relationship.; Another way to express this is.
Proportional Relationships Understand that a relationship between two variables, x and y, is proportional if it can be expressed in the form y/x=k or y=kx.
Distinguish proportional relationships from other relationships, including inversely proportional relationships (xy=k or y=k/x). Words in science are often used in different ways from ordinary English. Completely different meanings even occur in different branches of physiology, e.g.
for the word "accommodation". Inversely Proportional Problems There are also many situations in our daily lives that involve inverse proportion.
For example, the number of days required to build a bridge is inversely proportional to the number of workers.
