![]() Various scientists investigated the nature of air and oxygen in the 17th and 18th centuries. Display: TBC Oxygen – O – element 8 History: Elemental nitrogen is used as an inert atmosphere and as a cryogenic liquid. Nitrogen compounds have a huge range of applications from fertilisers to explosives. The association was that nitre was used to make an acid (nitric acid) of which nitrogen was a key element. In 1790, Jean-Antoine Chaptal proposed the name nitrogene from nitre, the French name for potassium nitrate, and Greek -gene meaning to produce. Antoine Lavoisier proposed the name azote from Greek meaning no life, as animals and flames died in pure nitrogen, and whilst this was adopted in other languages, only the chemical term azo- was adopted in English, as did the name pnictogen (Greek for producing suffocation) for the group to which nitrogen belongs. Rutherford did not identify it as an element and several other contemporary scientists also investigated it and proposed the names burnt air and phlogisticated air. Even though 78% of the Earth’s atmosphere is nitrogen gas, it was only discovered in 1772 by Daniel Rutherford who called it noxious air. Display:Ĭarbon fibre, anthracite coal, charcoal, graphite brushes from a motor and graphite electrodes, low density polyethylene and different allotropes of carbon: diamonds (loose), diamond-tipped drill bit, graphite, fullerenes (carbon nanotubes), graphene (in solution) Nitrogen – N – element 7 History:Īmmonia, nitric acid and nitrate salts were known, in some cases, since ancient times. Carbon has a crucial biological role and all plant and animal products contain carbon. Carbon fibres are used in woven materials. Uses:Ĭarbon’s main industrial uses are as a fuel (coal, oil, and gas) and for making plastics, it is combined with iron to make steel, and diamonds are used in cutting and drilling tools. They proposed the name carbone after the Latin carbo meaning charcoal. Vandermonde did the same with graphite, previously believed to be a type of lead. Similarly, in 1786, Claude Louis Berthollet, Gaspard Monge, and C. In 1772, Antoine Lavoisier showed that diamonds and charcoal produced the same reaction products when burnt. Display:Ĭarbon was known since prehistoric times in the form of charcoal, however it was not known that diamonds and graphite are the same element. Boron compounds such as borax and boric acid are used domestically as cleaning products, insecticides, and food additives amongst other uses. ![]() Uses:īoron is used as an additive in glass, particularly fiberglass and borosilicate glass, and in ceramics. The name boron was adopted by analogy with carbon. In 1808 boron was isolated independently by Joseph Louis Gay-Loussac and Louis Jacques Thenard, and Humphry Davy who proposed the name boracium, after the mineral borax. Together with groups 17 and 18, these elements form the p-block.Īlthough boron-containing minerals were known historically, boron compounds were not used widely prior to the 19th century when the mineral borax became widely available. The lighter group 15 elements can form anions with a -3 charge, and the lighter group 16 elements can form anions with a -2 charge. ![]()

Contrary to this is the transverse lie, in which the fetus is positioned 90° with respect to the mother's dorsal column. This is the most common lie of fetuses in labor. If the fetus and maternal column are parallel (on the same long axis), the lie is termed vertical or longitudinal lie. Using the techniques described above, the clinician should be able to develop an assessment of the relationship between the fetal and maternal dorsal columns (the longitudinal axis of the human body). The ultrasound should be 100% accurate in diagnosing the type of fetal presentation. If the presenting part is not easily palpable, it is important that further assessment be obtained by performing an ultrasound examination. The vaginal examination also allows the clinician to assess the degree of cervical dilation and effacement. The status of the amniotic membranes and the degree of engagement of the presenting part are indicators of fetal presentation and position. This maneuver should allow the identification of the fetal parts in the lower pole of the uterus.Īfter the abdominal examination, a digital vaginal examination is performed. The palms of both hands are placed on either side of the lower maternal abdomen, with the fingertips facing toward the pelvic inlet. Maneuver IV: This last maneuver resembles the first one, but instead of facing the fundus, the examiner faces the pelvis of the patient. This will allow the examiner to develop a further identification of the presenting part and assessment of its engagement. This is done on the lower abdomen, a few centimeters above the symphysis pubis. Maneuver III: Using one hand, the examiner will grasp the presenting part between the thumb and fingers. With this maneuver, the examiner will be able to determine the location of the fetal back. Maneuver II: Once an assessment is made of the fetal part present in the uterine fundus, the hands are placed at either side of the maternal abdomen. This should allow the identification of the fetal parts in the upper pole (fundus) of the uterus. The fundus is palpated with the fingertips of both hands facing toward the maternal xiphoid cartilage. Maneuver I: The uterine contour is outlined. ![]() (Pritchard JA, MacDonald PC: William's Obstetrics, 16th ed. The fetus is in a left occiput anterior position. What follows is a description of these maneuvers:įig. The accuracy of Leopold's maneuvers can be hampered by the maternal body habitus, the presence of uterine fibroids, multiple gestations, or polyhydramnios. Through use of Leopold's maneuvers, a clinical estimate of the fetal weight also can be obtained, although this is not a formal part of this examination. In addition, a clinical estimate of the degree of engagement of the presenting part could be made, although the final determination of engagement must be made by way of a vaginal examination. The examiner may be able to palpate the presenting part. Leopold's maneuvers 1 consist of an abdominal examination divided into four steps of palpation of the gravid uterus and fetus (Fig. ![]() The obstetrician should be able to determine the fetal lie, presentation, and position, using the maternal vertebral column and pelvis as reference points, by Leopold's maneuvers, vaginal examination, and if necessary, ultrasound. To assess the potential impact of the fetus on the characteristics of the labor process, it is important that the obstetrician be knowledgeable of the basic concepts used routinely to describe how the body of the fetus is located in the uterus. ![]() ![]() This is a game based in “Motos” announced in 1985 (recorded in the “Namco Museum Remix”, known in Japan as “Let's Play Together!

It is a new type of game in which all operations are performed with a touch pen. Items that assist PAC-MAN, such as arrows and bombs, will also start moving when the player draws them.

Out of curiosity about what would happen, I renamed both of those files and then they synced just fine, and the number went down to 672, where it has hung ever since. VERY INTERESTINGLY, when I hovered over the icon to check the version number, I was able to see the name of a file that was supposedly uploading, and I found the file and saw that there was another one in the same folder with the little "syncing" icon next to it.
