Hysterosalpingography (HSG), also known as uterosalpingography, [1] is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. It is a special x-ray procedure using dye to look at the womb ( uterus ) and fallopian tubes. [ 2 ]
Allometry is often expressed in terms of a scaling exponent based on body mass, or body length (snout–vent length, total length, etc.). A perfectly allometrically scaling organism would see all volume-based properties change proportionally to the body mass, all surface area-based properties change with mass to the power of 2/3, and all length ...
where M is the total mass of the two bodies and k 2 is Moulton's notation for the gravitational constant. He defines c 1 , c 2 , and c 4 to be other constants of the motion. The notation C 3 probably became popularized via the JPL technical report TR-32-30 ("Design of Lunar and Interplanetary Ascent Trajectories", Victor C. Clarke, Jr., March ...
mass "The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the metre and the second are defined in terms of c and ∆ν Cs." [1] The mass of one litre of water at the ...
Human body weight is a person's mass or weight.. Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales.
The astronomical unit of length is now defined as exactly 149 597 870 700 meters. [4] It is approximately equal to the mean Earth–Sun distance. It was formerly defined as that length for which the Gaussian gravitational constant (k) takes the value 0.017 202 098 95 when the units of measurement are the astronomical units of length, mass and ...
It shows a normal endometrium as a hyperechoid (brighter) band around the cavity, in this case without any focal changes. Sonohysterography is a specialized procedure by which fluid, usually sterile saline (then called saline infusion sonography or SIS ), is instilled into the uterine cavity, and gynecologic sonography performed at the same time.
1 unit of pressure = 1 unit of force / (1 unit of length) 2 = 1 unit of mass / (1 unit of length × (1 unit of time) 2) 1 Ba = 1 g/(cm⋅s 2) 1 Pa = 1 kg/(m⋅s 2). Expressing a CGS derived unit in terms of the SI base units, or vice versa, requires combining the scale factors that relate the two systems:
