Lethbridge Herald (Newspaper) - February 27, 1973, Lethbridge, Alberta 16 - THE IETHBRIDGE HERALD - Tuesday, February 27, 1973 LAWRENCE E. LAMB, M. D. Digitalis, calcium By JEANE DIXON may cause trouble Dear Dr. Lamb - In your column, you stated that adults need approximately a quart of milk a day and in another column you stated that anyone taking digitalis should avoid excess calcium intake. Now my question is this. How much milk would be considered excessive for anyone taking digitalis? I am retired, age 69, weigh 195 pounds and take digitalis to contort a tendency toward paroxysmal tachycardia. My doctor tells me it is sate for me to ride my bicycle 20 miles a day which I do and feel great in doing it. Dear Reader - Individuals taking'digitalis and the various medicines that contain digitalis products will not Shave a;^' trouble drinking ordinary quantities, one to two quarts a day. The problem is that calcium tablets are available without prescription to the general public. This includes bone meal preparations and a number of �vitamin tablets with calcium. If you add these sources of calcium intake to ordinary milk intake, it could cause difficulties. For this reason, I think anyone who takes digitalis medicine regularly should avoid taking mineral tablets of other health foods without their doctor's recommendation. Sounds to me like you're doing rather well, if you are able to bicycle 20 miles a day. k* * Dear Dr. Lamb - I'd appreciate your comment on an article that stated that the combination of aspirin and alcohol are potentially dangerous. According to the article, aspirin sometimes causes small bleeding and alcohol can penetrate the stomach and cause the bleeding to be worse. I have been using two aspirins with a glass of wine at bedtime as a sedative and considered it safer than sleeping pills but now I am concerned about the effect on my stomach. If you agree with this article, what in your opinion woulri be a safe interval between the two? For example, if one had a couple of drinks and then later found it necessary to take aspirin. I am a 46-yeav-old grandmother and in good health except for being a little overweight with slightly high blood pressure for which I "take medicine under a doctor's supervision. Dear Reader - Small flakes of aspirin material will actually stick to the lining of the stomach and can burn small holes in it and can cause bleeding. Large amounts of aspirin also affect the clotting mechanism of the blood to cause a bleeding tendency. Because alcohol does c;.use the stomach lining to be engorged with blood and causes an increased secretion of acid juices by the stomach, I would really believe that the combination is not good. The best way to take aspirin is to take it at the end of a meal or to eat something when you take it, such as cottage milk. Milk will help to neutralize the acids in the stomach and help to prevent precipitating aspirin crystals on the stomach lining. It takes several hours to eliminate the effects of alcohol on the stomach. If one insists on taking the two, it would be better to take the aspirin first with a liquid neutralizer such as milk. Perhaps an hour or more later this would have been emptied from the stomoch and it would then be safer to have a glass of wine. Send your questions to Dr. Lamb, in care of this newspaper, P.O.

For a copy of Dr. Lamb's booklet on impotence, send 50 cents to the same address and ask for "Impotence" booklet WEDNESDAY, FEB. 28 Your birthday today: Relationships are erratic at best, with many sudden quirks of cirucumstances, odd timing, much excitement. Today's natives are generally conscientious, somewhat shy about assuming obligations, often interested in spoils and athletics. ARIES (March 21-April 10): With gentle care for those less fortunate, seek agreement amongst your equals, associates. Bright ideas are normal for today. TAURUS (April 20-May 20): It's quite all right to be satisfied with yourself in anticipation of what you may be able to do to improve your income. GEMINI (May 21-.Tunc 20): Effrontery now fails. If you are going to be bossy, be sure you have the authority. In personal relationships, you don't. CANCER (June 21-Jtily 22): Just being yourself may be all that is needed for a successful day. This is a good time to catch up on any neglected correspondence. LEO (July 23-Aug. 22): Get started on something you've been putting off - distasteful responsibilities are better borne early and without comment.

NORTH A 10 9 6 V A10 8 5 i 2 0 63 + 87 'WEST EAST AK854 AQJ72 CVoid V9 63 6 A 9 5 2 O 10 *AK1032 +QJ35* SOUTH A A3 Pass Pass Dole. Pass Pass Pass Opening lead: King of A West muffed several opportunities to defeat South, the declarer at five hearts doubled in today's hand. The auction was highly competitive and, when North sacrificed at five hearts over five clubs, West chose to double. Altho his side could have made six clubs, losing only one spade trick the partnership's perfect fit was extremely difficulty to identify and he decided to try instead for a small profit by defending on the deal. West opened the king of clubs and East, to whom it was quite obvious, that a second round of the suit would not go thru, signalled dis-eouragingly with the four. It appeared desirable to establish a spade trick, and he hoped to induce a shift from his partner while the defense Ktill retained the initiative. West chose to ignore East's signal, and he continued woodenly with the ace of clubs which declarer ruffed. 5outh proceeded to draw trumps with three pulls ending up in dummy, as West discarded a spade and two clubs. If diamonds had divided three-two, declarer's work would have been routine, for after driving out the ace, his diamond suit is established for several discards, and he retains the ace of spades as an entry to his hand. In order to improve his chances in the event that the diamonds did not split, South resorted to a bit of guile. Two extra rounds of trumps were led from dummy on which the declarer discarded the four and seven of diamonds. Observe that he can spare these cards inasmuch as only two spade discards are required from the North hand. On the fourth heart West discarded a second spade, but on the next round, he let go a small diamond. South led a diamond to the jack which West ducked. He took the king on the next lead and led a club to force out North's remaining trump as declarer discarded the three of spades. A spade put South in with the ace and the queen and eight of diamonds took the last two tricks. A spade shift by West at trick two, while he retained the ace of diamonds, would have assured declarer's defeat. West could have dispatched his opponent even more promptly by giving his partner a diamond ruff; however, he is not chargeable for failing to diagnose that East had a singleton diamond. What is more to the. point is that West could have effected a late recovery by holding on to all of his diamonds, discarding, for *x-nmple, his last club. When South leads a dia. mond from dummy, West covers the jack with the ace. The king of spades is returned dislodging declarer's ace. He cashes the king and queen of diamonds and discards one spade from the North hand. However, West retains a stopper in the suit and East eventually scores the setting trick with the queen of spades. activities you gain a deeper pti.'spective on yourself and your work - there's much to do yet. LIBRA (Sept. 23-Ocl. 22): A long-standing question comes near resolution - you may be relieved at your reaction to not having to consider the question. SCORPIO (Oct. 23-Nov. 21): Differences of opinion exist, can easily become quarrels. See whether you can stay out of a game of trading harsh words. SAGITTARIUS (Nov. 22-Dec. 21): You are apt to plunge right into self-expressive projects without thinking of costs or reactions amongst your friends. CAPRICORN (Dec. 22 - Jan. 19): The pitch begins with "why don't we . . ." and from there it's a gamble if you join the scheme. You've lots of energy. AQUARIUS (Jan. 20-Feb. 18): An inner streak of mischief loads you to the words and deeds that dismay your associates-with the best intentions, PISCES (Feb. 19-March 20): You can't sit back and watch life happen to you especially today. You must get up and going and busy making things happen. PEANUTS Ask Andy � Semiconductors Andy sends a complete 20-volume set of the Merit Students Encyclopedia to Bruce DeVries, age 13, of Munde-lein, Illinois, for his question: How do semiconductors work? Eveiybody's favorite semiconductor devices are radio transistors. They put music in your pocket, go where you go and ignore regular plug - in house cm-rent. Such devices are smaller and neater, more durable and economical than old style radio and TV tubes. They are remarkable because they drive energy by making ordinary electrons perform extraordinary feats. Wherever there is any sort of electrical energy, the key particles behind the scenes are moving electrons. Generators create house current by pushing electrons through copper wire circuits. Conductors and insulators are used to keep the power rolling. Copper is a conductor material because its atoms have loosely attached electrons that are prone to roam. Silicon is an insulator because its crystalline lattice structure puts a stop to roaming electrons. Our mighty generator systems depend upon conductors to carry the current and upon insulators to barricade the leakages. Semiconductors discard this old system and get electrical energy from insulators. Rectifiers, amplifiers, oscillators and dozens of other electrical devices prove that they work. But at present, scientists are not sure what makes these semiconductors work. The secret is in the chemical recipe and what it does to an insulator's crystalline lattice. The main ingredient may be silicon - but it must be infiltrated with a trace of some selected impurity. An n-type semiconductor may be silicon with a trace of arsenic. When boron is the impurity in the silicon, it creates a P-type material. Various N-types and P-types are molded in thin sheets. Electrical energy is created when opposite types are sandwiched together in slim wafers. A semiconductor works because at the atomic level, negative and positive charges attract each other - somewhat like the opposite poles of two magnets. Electrons are negative charges. In one of our sample recipes, atoms of arsenic added electrons to the silicon lattice. This made an N-for - negative - type material. In the other recipe, boron atoms removed electrons from the silicon lattice leaving holes. For reasons unknown, the holes in a P-type material act like lllllllllllilil! positive charges. In wafers of P-layers and N-layers, opposite teams of potential energy face each other across junction zones. A boost from a small battery can start the action. Positive and negative charges attract each other across the junction, where their mobile breezes can be drawn off as electric current. * * The most widely used insulator ingredients are silicon and germanium. Traces of arsenic, phosphorous or antimony may provide the mobile negative electrons in N-type materials. Traces of aluminum, gallium or boron may add.the positive holes in P-type materials. Pure silicon may be a billion times better as an insulator and pure copper a billion times better as a conductor. B u t those mixed up semiconductors have mysterious talents of their own. * * * Andy sends $10 to Debra Vysc, age 13, of Peterborough, Ontario, for her question: What is the San Andreas Fault? This fault, as no doubt you suspect, is a geological feature associated with earthquakes, similar weak crustal zones around the Mediterranean were noted by early geologists. Later, others were traced in the New World, especially around the rims of the Pacific Ocean. One of the most famous of these is the San Andreas Fault. It extends from Mexico, through central California to north of San Francisco. There it leaves the land and travels on through the ocean floor. Geologists see it as a fractured zone where enormous crustal plates are pushing against each other. Stupendous pressures build up deep underground. In time they become critical and the stresses are relieved by sudden earthquakes. The San Andreas causes numerous small quakes in California and occasionally a big one. Farther south, similar fault zones caused the recent disaster in Nicaragua and major earthquakes in Peru. Questions asked by children of Herald readers should be mailed to Ask Andy, P.O. Box 7G5.
