International conference on transition and cord clamping at birth April It is increasingly recognised that the circulatory changes involved in transition at birth cannot occur within a few seconds of birth. While the healthy fetal circulation and the healthy neonatal circulation are moderately well understood, the underlying triggers, the precise sequence and speed of the changes in the circulation are not. How can we interefere in something we do not understand? Nearly all textbooks and journals which include the physiological transition of the neonate at birth describe a marked change in the peripheral vascular resistance and an increase in the afterload of the heart. One notable exception is Gray’s Anatomy. Gray’s Anatomy describes inflation of the neonatal lungs as the first change after birth and does not describe any changes in the afterload of the heart. Afterload is the force that the myocardium generates during ejection against systemic and pulmonary vascular resistances. Reductions in afterload increase stroke volume if other variables remain constant.

What is the Orloj? Basically, the Orloj is a clock with a history line better than a Grisham novel plot, see below. It does astronomical ‘things’ and also entertains about every tourist who comes to Prague for at least three minutes. The famous saying “See Naples and die” can be used in the case of the Orloj but we suggest in modifying it to “Don’t die before you see the Orloj! What’s the big deal?
But the combined beauty of the Orloj, the hourly mechanical ‘show’ and above all – the crowds that gather below it, even with still 15 minutes to go Standing under the Orloj at the chime of the hour is not just simply gaping at an old clock. It’s an experience that everyone who comes to Prague should undertake and only then will you understand the real magic of the Orloj.

Carbon 14 Dating Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.
One of the great joys of the Internet has been the spread of dating agencies. It wasnt all that long ago that the physical equivalent, the marriage bureau or introduction agency, was seen as something for losers or the slightly desperate. There has been a long standing tradition within certain cultures of having marriage brokers, but that has never really been mainstream. Most people met friends, lovers and mates either through family connections or sheer geographic proximity the girl next door, for example.
This has now changed with the way in which we no longer live in such tight knit communities. Women have moved into the workforce in great numbers, and are now a majority on most college campuses. This might, you would think, mean that there was in fact less need for dating agencies, but this isnt the case. We no longer work near where we live; our lives are ever more atomized.

Because the exact date of embryo transfer is known, the due date calculation is more precise. However, a due date is only an estimate: Normal term gestation is generally defined as weeks, and a baby may be born any time during that period. The due date is just an estimate — not a requirement. Ovulation and conception occur 14 days after the start of the menstrual cycle on average. For example, if the last menstrual period was May 1 and it is now June 1, the baby was probably conceived around May 14, the gestational age will be 4 weeks, and the due date will be February 4 of the following year.
Calculations for natural conception are not necessarily very precise because of several factors. First, if the pregnancy was unexpected, the woman may not remember the date of her last menstrual period.

Peak Ovulation Please note that this is only an estimation of your menstrual cycle If you want to stand the best chance of getting pregnant, then you need to know when you are ovulating. This is the time of the month that you are at your most fertile, and thus stand a greater chance of a sperm reaching the egg and fertilizing it.

It contains over calculators, starting with mechanical machines dating back to at least the s to electronic pocket calculators beginning in I remember a man coming to my eighth grade math class in or and showing us a desktop electronic calculator costing hundreds of dollars. It did the difficult math we were doing almost instantaneously. While I was in high school the first pocket calculators came out.
Not having a calculator for math through grade 12 made me good at doing hand calculations, and gave me a great appreciation for calculators. The Calculator Museum is divided into several sections generally by manufacturer. The largest holdings are Texas Instrument TI calculators. LED stands for light emitting diode. With LED displays the numbers light up in red. LCD stands for liquid crystal display. LCD displays usually have black numbers against a silver background.
At the time of LED displays, there were also vacuum fluorescent displays displaying greenish or bluish numbers. LCD displays rapidly took over since they use a tiny fraction of the energy of a LED or fluorescent display and hence batteries rarely need to be replaced. LCD calculators are also much smaller.
