Lethbridge Herald {Newspaper} - 1974-01-15,Lethbridge, Alberta »—THl HTHBHIPQt HIRALP—Tu—dty, January 19,1t74 UGHT1NG A MATCH Andy sends a complete 20-volume set of the Merit Students Encyclopedia to Andrea Zak, age 11, of Winnipeg, Manitoba, for her question: How does ftrlking llglit a match? The two words match and safety go hand in hand. There are safety matches, designed to reduce the risk of fires. And a sensible person always thinks of safety when he or she strikes a match. But even the safest match is not foolproof. So when the flame has done its work, we kill it dead and make sure there is no smoulderiitg afterglow. One sensible habit is to break the dead match stick in two, which makes sure that it has no secret heat to start up another blaze on its own. « * « The secret of a match is a clever chain reaction, based on chemical kindling points. In the moment it takes to strike a light, the operation goes from warm to wanner to a blazing flame. And each stage has its own secret kindling point. There are many burnable substances and each catches fire at its own special kindling point temperature. Paper needs only the heat from a match flame. Sticks need the extra heat that comes from burning paper. Heavy need lots of heat from burning sticks before they catch fire. This is why we use paper and sticks to get a log fire started. Somewhat the same idea is used to make a match. But instead of paper and sticks, they use mixtures of burnable chemicals. One of the mixtures in the match head has a very low kindling point. All it needs is a little warmth created by friction. As you know, when you mb your finger back and forth on a smooth surface, the friction makes it warm. When we strike a match head on a rough surface, there is enough friction to activate one of its chemical mixtures. Vapors, oxygen and warmth from this operation trigger the other chemicals in the match head to burst into flame. All it takes to start this chain reaction of bumioj chemicals is a little warmi created by friction. Safefy matches are made to strike only on the rough patch provided on the package. Kitchen matches are made to strike on any rough surface — so it’s up to us to use a lot of careful common sense when we use them. Many different chemicals and mixtures of chemicals can be used to create a strikeable match. As a rule, the manufacturers use mixtures of potassium chlorate BY CHARLES H.

The heat from this stage decomposes the potassium chlorate, releases oxygen and enough extra heat to start the flame. • * « Manufacturers strive to make their matches as foolproof as possible. For example, a wooden match stick is soaked in borax or some other chemical that retards a smouldering afterglow, are built around match so that they do not rub arainst each other and imite themselves in the box. However, so far nobody has Invented a perfectly foolproof match — so let’s always beware.

The museum was founded by a bequest in 1753 of books and antiquities from Sir Hans Slone and was quickly built up by royal donations and other private bequests. Today, the museum owns more than six million books and 75,000 manuscripts among a multitude of other valuable items. 192* — The Irish Free State was established. 1920 — ’The last drinking day before Prohibition was instituted In the United States. 1892 — The rules of basketball were published. 1870 — A donkey was first used as the symbol of Oie U.S. Democratic party. 1535 - The Act of Supremacy, marking control of the English monarchy over the Church, was passed. PLAN ALBERTA BRANCH TORONTO (CP) ~ Unity Bank of Canada, in its second year of operation, plans to open a branch in Calgary, its first in Alberta. It wiU open in late February as Unity’s 17th branch in Canada. There are three other Western Canada branches, two in Vancouver and one in Winnipeg. WEDNESDAY, JANUARY 16 Yovr birthday today: The pursuit of creativity, romance, adventure characterizes your approach to life this whole year, Expectations run high and low by turns, contributing intense anticipation-tension and early preparations for all sorts of circumstances, some of which never materialize. Relationships run complex and deep, must weather occasional moods. Today’s natives suffer perpetual impatience which is only partly worked off in pastimes and mental pursuits, ARIES (March Sl-April 19) : Hold your hasty words until you hear both sides. If you want publicity, this is the time to try for It, with results indicated two days later. TAURUS (April 20-May 20); I Take it easy where you can, play it safe as best you may. Your self-discipline and tact in the face of comment make all the difference in what comes next. GEMINI (May 21-June 20): Let financial arrangements run as they are for the ; iresent. Meanwhile, collect i urther facts and figures on proposed changes. CANCER (June 21-Jaly 22); Your view and theories are likely to find some vindications and support along with whatever opposition you arouse by the way you present them. LEO (Jnly 23-Aug. 22); What happens today is largely the consequence of your impulsive moves of some time ago, subject to moderation or redirection. Make the best of what comes. VIRGO (Aug. 23-Sept. 22): Get busy early to take care of those neglected chores, promises you’ve made and haven’t renewed or redeemed, being very shy about making more. LIBRA (Sept. 23-Oct. 22); It’s time to gather your avail-ble resources, or at least review them in the light of some promising plans. You may have interesting second thought. SCORPIO (Oct. 23-Nov. 21); Your early diligence turns the tide, and things seem to spin around and come your way. Persuasion brings better results than demands. SAGITTARIUS (Nov. 22-Dec. 21) : Discretion becomes a rare achievement today; at least try for it! You’ve been moving along at a pretty fast rate lately, perhaps too fast. CAPRICORN (Dec. 22-Jan. 19);    Strict economy is important now, for time and energy as well as money. You can improve your position by being willing to put in the necessary work. AQUARIUS (Jan. 20-Feb. 18) : What may seem to you a rather ordinary idea may excite or disturb some other people. There is postive benefit in letting most controversies pass. PISCES (Feb. 19-March 20)    ; Much that appears to be merely outside distraction is really something you ought to examine, consider seriously — and do something about, soon. 1974, The Chicago Tribune higher by himself. As the cards lie, a contract of five spades by East*West could be doublet) and set two tricks with accurate defense, for a penalty of 500 points. The opening lead of the nine of spades was ruffed in the closed hand. A trump was ted to the jack, drawing both the opponents' trumps in the process and another spade was ruffed- The king and ace of diamonds were cashed, and the king of spades was led from dummy. East covered with the ace. and instead of ruffing, declarer discarded his losing diamond. This loser-on-loser play had a dramatic effect. Un-* less East took his ace of clubs there and then, he would have failed to take a trick with it. A spade would allow declarer to discard a club while ruffing in dummy, ihen set up diamonds with a ruff while a trump still remained in dummy. Note that declarer’s line of play would have insured eleven tricks even had trumps broken 2-0. The basic line of play is the same, except that declarer draws a second round of trumps before cashing the high diamonds and throwing East in with the ace of spades. DEAR DR. LAMB - The nervous system is very interesting to me. Electroencephalography (EEG) especially interests me since I have just had such a test. Is the EEG accurate in most cases, and would you give me a little information about it. Could you describe how to detect certain abnormalities? DEAR HEADER - Whole books are written on this subject, so I can only scratch the surface. The brain cells send out electrical Impulses regularly. The effect is similar to the constant pulsing of a fluorescent lamp. These constant electrical pulses can be measured and plotted against time on a strip of paper. That is what the EEG graph is, a record of the changing electrical pulses traced out along a graph or time base. The impulses are measured by the electrodes attached to the .scalp. In clinical tracings of this type only the surface electrical activity of the brain or the cortex area is really measured. The deeper electrical activity doesn’t reach the surface. The electrical pulses of the cortex brain cells have been classified according to how fast they are (frequency), how large they are (amplitude) and how regular or rhythmic they are. Lack of oxygen to the brain will cause large slow waves. An abnormal area of electrical activity in the brain may cause sharp spike waves. Sleep produces changes in the waves and so does dreaming and rapid eye movements (REM). The large number of electrodes are used to find the area of the brain that is involved in producing the electrical pulses. A good example here would be the person who has a spot in the brain that fires off large electrical pulses or spike waves. Such a spot of overactive brain cells can cause a convulsion. The escessive electrical pulse behaves like lightening striking and abnormally stimulates a lot of other brain cells that control the arm, hand, face, leg and body movements. The rapid irregular stimulation of these cells results in the convulsion. Using several electrodes and looking at the electrical pattern, it is often possible to locate where the spot is that is. causing the problem. Using similar techniques, a brain tumor can often be iden tified and its location determined. Interpreting the EEG is a difficult task. In the hands of a well-trained, experienced neurologist they can be immensely useful. EEG's won’t always show everything because only part of the brain is measured this way. But it is one of our best diagnostic tools in selected cases. How accurate it is depends on what it is used for. By using other procedures to stimulate the brain its usefulness can be expanded- To a very large extent its accuracy and usefulness depends on how well the record is taken and the skill of the person who interprets the record. A good record is not useful in complex problems unless the person who interprets it is highly skilled in its use. Send your questions to Dr. Lamb, in care of this newspaper, P.O.
