⑥ 전치태반
-완전 전치태반이라고 하여 자궁구를 전부 막고 있는 경우는 반드시 제왕절개를 하게 된다.
-태반의 일부가 자궁구를 막고 있는 부분 전치태반이나 태반의 주변이 자궁구에 접해 있는 변연 전치태반의 경우도 최근에는 출혈의 위험 때문에 재왕절개 하는 병원이 많아지고 있는 추세이다.
Observation of a capillary phenomenon
Setting temperature : 20ºC in the room
Measurement of height of liquid in two capillary tubes
(Small tube and Large tube)
Calculation of the Surface tension(γ) of liquid
Assume that cosΘ ~ 0.9 (Contact angle : 22.5º ~ 30º)
Thus, γcosΘ value can give the information about Approximate value of Surface tension(γ)
γcosΘ value for t
OBSERVATION DOME on top
of the ship. In the Dome sits TALBY. He is staring around,
wide-eyed, at the planets and stars.
DOOLITTLE
(over - filter)
Talby, Talby, this is Doolittle. Do you
read me? Talby?
WE MOVE IN CLOSE ON TALBYS FACE. The shot stops and holds
as he continues to stare, rapt.
DOOLITTLE
(contd - over - filter)
Talby, do you read me?
There is a CRACKLE, and Doolittles voice suddenly
observed in these particles, possibly due to strong absorption by carbon.). For example, a 10nm size particle was selected Fig.3a and a spot analysis was conducted. From the acquired spectrum Fig.3b, the particle was identified as another Nb precipitate. Prior to this study, it was certain that Nb precipitates as particles above 50nm in steel, but identifying precipitates below this size was not
(2) Column Chromatography
Column chromatography에서는 stationary phase와 solid adsorbent가 vertical glass column에 위치하고 mobile phase인 solvent는 column의 위에서 가하여 아래로 흘러내리게 한다. 이 때, gravity를 이용하는 것과 external pressure를 가해주는 두 가지 경우가 있는데 압력을 가해주는 방식이 좀 더 빠르게 column을 흘러
