History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.

Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery.

The nuchal translucency measurement can be taken during the dating scan. If you have agreed to have screening for Down’s syndrome, the dating scan and the screening will usually happen at the same time.
This is most commonly done at around weeks of gestation. Sometimes during a third trimester ultrasound, findings reveal that the baby would be safer in a neonatal intensive care unit than to remain in the uterus. What is a pregnancy ultrasound? These sound waves are higher than can be registered by the human ear, which is why pregnancy ultrasound is a quiet procedure.
The sound waves are emitted from a small, vibrating crystal housed in a hand-held device known as a transducer. It is a painless procedure and will not hurt you or your baby. During pregnancy ultrasound, the sound waves which are created bounce off the baby and in turn are interpreted into an image on a screen. These images are occurring in real time; there is no delay between when the images are picked up and when they can be seen on the screen.
Hard tissues such as bone appear as white and soft tissues appear as grey. Amniotic fluid appears black because the sound waves just go through them as there are no firm tissues for them to bounce off.

Aircraft were launched and retrieved by means of a trapeze, and could enter and exit the hangar though a large T-shaped opening at the bottom of the hull. As naval airship doctrine eventually developed, rather than the airplane extending the scouting range of the airship, it was the airship which extended the scouting range of the airplane. The Navy contest to design and build the two new ships was won by the Goodyear-Zeppelin Corporation, a joint venture and patent sharing arrangement between the Luftschiffbau Zeppelin and the Goodyear Tire and Rubber Corporation which had been created in There was no serious competition for the contract, and it was clear to everyone involved in the process that Goodyear-Zeppelin was the only firm with the ability to design and construct these ships for the Navy.
Goodyear-Zeppelin and the United States Navy signed a contract for the construction of two large rigid airships on October 16, F9C-2 hooked on trapeze left and stowed on hangar deck right Structural Design of Akron and Macon As part of the Goodyear-Zeppelin arrangement, the Luftshiffbau Zeppelin had sent technical experts to Akron to train Goodyear employees in the design and construction of airships.
Shenandoah crash after suffering in-flight structural failure during a storm. The deep-ring design also accommodated a Navy requirement that all areas of the structure be accessible during flight; the 8-foot deep rings were large enough for a man to climb their entire circumference. The main keel, at the top of the ship, provided access to the valves for the gas cells, and the two lower keels provided support for the engines and crew spaces. Engines and Propellers The three-keel arrangement, along wth the use of non-flammable helium, also allowed the engines to be carried internally, along the lower keels, rather than in external power cars; this significantly reduced aerodynamic drag and allowed for easier access and maintenance of the engines.
Akron The hp Maybach VL-2 engines were connected to outrigger propellers by long shafts with bevel gears which allowed the propellers to be rotated to provide thrust not only forward and reverse, but also vertically downward to assist in takeoffs and landings. The mounting of the engines on the two lower keels did create one design element which was accepted only as a compromise; the four engines on either side were mounted in a straight line, and not staggered as the external power cars of earlier zeppelins had been.
In earlier zeppelins, the staggering of engines at differing heights along the hull allowed each propeller to operate in clean air, undisturbed by the prop wash from the engine in front of it, whereas the propellers on Akron and Macon operated in the disturbed air created by the engines ahead of them.

I’m at an outer-London maternity unit and they were fantastic. At this stage of your pregnancy you will be starting your antenatal care and will be offered a dating scan around 12 weeks. We do not know exactly why babies get Down’s syndrome. The dating scan can include a nuchal translucency NT scan, which is part of the combined screening test for Down’s syndrome.

wks from LMP. In OB ultrasound, dating is based on menstrual age (beginning with the first day of the mother’s last menstrual period) and not the actual date of conception. The heart starts beating during the 3rd week after conception (5 weeks from lmp) and can be seen with a transvaginal scan.

how accurate was your EDD from early ultrasound dating scan
I got my scan date through about weeks after my midwife appointment and was scanned at exactly 12 weeks, however at the scan I was dated as being 12 weeks and 5 days gone. They then booked my 20 week scan at the end of my 12 weeks scan so I had that date straight away.
Reinhardt Reinhardt is an old soul looking to make his impact on the world. His interest include business, robotics, engineering, fitness, swimming, and more. Lots of women bashing. Some of these countries include Thailand, Singapore, Philippines, etc. For this article, I will speak only about Japan; having been there myself. Men on this site preach the red pill but forget that it applies to all women, not just women in certain countries.
So with that said, it is time I debunk some of these myths and bring you the reality.

Above graphic from Mutha Crafter. Visit her shop here. We have it ingrained in our heads throughout our entire adult lives-pregnancy is 40 weeks. The “due date” we are given at that first prenatal visit is based upon that 40 weeks, and we look forward to it with great anticipation. When we are still pregnant after that magical date, we call ourselves “overdue” and the days seem to drag on like years.
The problem with this belief about the 40 week EDD is that it is not based in fact.

See Article History Military communication, the transmission of information from reconnaissance and other units in contact with the enemy and the means for exercising command by the transmission of orders and instructions of commanders to their subordinates. As such, it comprises all means of transmitting messages, orders, and reports, both in the field and at sea and between headquarters and distant installations or ships. Military communication has thus long played an important role in warfare.
Early development Messengers have been employed in war since ancient times and still constitute a valuable means of communication. Alexander, Hannibal, and Caesar each developed an elaborate system of relays by which messages were carried from one messenger post to another by mounted messengers traveling at top speed. They were thus able to maintain contact with their homelands during their far-flung campaigns and to transmit messages with surprising speed.
Genghis Khan at the close of the 12th century not only emulated his military predecessors by establishing an extensive system of messenger posts from Europe to his Mongol capital but also utilized homing pigeons as messengers. As he advanced upon his conquests he established pigeon relay posts across Asia and much of eastern Europe. He was thus able to use these messengers to transmit instructions to his capital for the governing of his distant dominions. Before the end of the 18th century European armies used the visual telegraph system devised by Claude Chappe , employing semaphore towers or poles with movable arms.
The Prussian army in assigned such visual telegraph duties to engineer troops.
