Some studies are cited as being too small or having too many confounding factors to draw any useful conclusions. It is difficult to know what to believe Today, millions of ultrasound exams have been performed and millions of babies have been exposed during pregnancy. Without dramatic birth defects to stop its use, more subtle biological sequela may go unrecognized for years to come. Reviewers analyze huge numbers of studies and create a meta-analysis of research data about these issues. The third edition of the book concludes the following about the potential hazards of obstetric ultrasound: Any consideration of the use of diagnostic ultrasound in obstetrical practice must weigh potential benefits against potential risks. There has been surprisingly little well-organized research to evaluate possible adverse effects of ultrasound exposure on human fetuses.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them.

Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing. However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to have these prenatal tests, even though the tests are often difficult to interpret. It is further designed to address the special concerns that large women might have in taking these tests their fears, any special equipment or techniques that might be helpful, the controversies over interpretation of results, whether large women have a higher rate of so-called ‘false-positives’ on certain tests and why, etc.

Having this information in advance of the birth means that healthcare staff as well as parents can better prepare themselves for the delivery of a child with a health problem. For example, Down Syndrome is associated with cardiac defects that may need intervention immediately upon birth. Many expectant parents would like to know the sex of their baby before birth. Methods include cell-free fetal DNA analysis , amniocentesis with karyotyping , and prenatal ultrasound.

In some countries, health care providers are expected to withhold this information from parents, while in other countries they are expected to give this information.

I have said, in the past, that you should move toward full frame sensors. I have always championed full frame sensors. At the end of the day, full frame sensors beat APS sized and smaller sensors. The whole reason I bought an original x was because it had the largest sensor I could find in a small camera.

It had been a number of years since I had shot an APS crop frame sensor. I replaced that with a Nikon D3 full frame and then moved on to the Canon 5d2, also full frame. Full frame cameras are better. I started shooting personal work with my little Fuji. Then I pulled it out on jobs from time to time because I loved that little camera.

I got my hearing aids from the audiology department at a local university. The audiologist handed them to me and that was that. After surfing the Hearing Aid Forums I found out that digital hearing aids are adjustable by the user and that all this time, I could have been making all kinds of little adjustments.

Overview Reference Overview of vintage embroidery transfers Vintage embroidery transfers have regained popularity today, thanks in no small part to advances in technology that allow designs to be programmed and machine-stitched with beautiful results. Improved fabric paints, dyes and markers allow these great old designs to be used by even the needle-challenged. And, of course, those who enjoy the satisfaction and quality of hand-stitching still use them the “old-fashioned” way. Embroidery transfers have been available from many, many different companies for well over a hundred years.

So whether you’re looking for breathtakingly intricate motifs for heirloom embroidery, authentic designs for period costumes, particular motifs to complement a collecting interest, or a comical design to enliven your kitchen towels, there’s a huge assortment of vintage designs waiting to be rediscovered. This overview addresses a major roadblock for the vintage embroidery transfer enthusiast — the lack of organized material about vintage transfers. Old catalogs are scarce or non-existent , companies have gone out of business — histories and product lines have to be pieced together from scraps of information scattered across web pages and collections.

So here’s a launching place for research about the designs and the major companies that produced embroidery transfers dating back to the late s. It’s an ongoing reference project open for use by everyone who enjoys vintage transfers. Naturally its value to the stitching community depends on accuracy and depth of information. Whenever possible information has been checked with two or more sources and educated guesses are identified as such.

Of all of these uses, dating the pregnancy is the most common reason to use ultrasound, particularly when the expectant mother cannot remember the date of her last period as in breast-feeding or irregular cycles.

When an ultrasound is performed, measurements of the head, abdomen, thigh, and amount of amniotic fluid are done. This creates error in that the baby will compute out to be further along than he or she really is. For instance, say you normally have eight and nine pound babies.
