# The perinatal mortality rate, the sum of neonatal deaths and fetal deaths ( stillbirths ) per 1000 births.

# The maternal mortality ratio, the number of maternal deaths per 100, 000 live births in same time period.

# The maternal mortality rate, the number of maternal deaths per 1, 000 women of reproductive age in the population ( generally defined as 15 – 44 years of age ).

# The infant mortality rate, the number of deaths of children less than 1 year old per 1000 live births.

# The child mortality rate, the number of deaths of children less than 5 years old per 1000 live births.

# The age-specific mortality rate ( ASMR )-This refers to the total number of deaths per year per 1000 people of a given age ( e. g. age 62 last birthday ).

# The early mortality rate, the total number of deaths in the early stages of an ongoing treatment, or in the period immediately following an acute treatment.

# The late mortality rate, the total number of deaths in the late stages of an ongoing treatment, or a significant length of time after an acute treatment.

# Experimental mortality, or differential loss of respondents from the comparison groups.

# Lipid-lowering therapy should be used for secondary prevention of cardiovascular mortality and morbidity for all patients ( both men and women ) with known coronary artery disease and type 2 diabetes.

# Infant and under-5 mortality ( U5MR ): reduction by one third in infant mortality and U5MR

# Reduction of infant and child mortality: Countries should strive to reduce infant and under-5 child mortality rates by one-third or to 50-70 deaths per 1000 by the year 2000.

# Reduction of maternal mortality: A reduction by ½ the 1990 levels by 2000 and ½ of that by 2015.

# Understory reinitiation: trees die from low level mortality, such as windthrow and diseases.

Because cardiovascular disease is the # 1 cause of mortality in first-world nations, this delay of heart failure would increase the average lifespan of men by six years and women by 5. 5 years.

In the EPA ’ s 1999 Federal Guidance Report # 13 ( FGR 13 ), Cancer Risk Coefficients for Environmental Exposure to Radionuclides, the authors conclude that women have a 48 percent higher radionuclide-related cancer mortality risk than men.

# The carbon-hydrogen ratio is high.

How Gerrymandering can influence electoral results on a Voting system # Nonproportional and semiproportional methods | non-proportional system. Example for a state with 3 equally sized districts, 15 voters and 2 parties: Plum ( squares ) and Orange ( circles ). In ( a ), creating 3 mixed-type districts yields a 3 – 0 win to Plum — a disproportional result considering the state-wide 9: 6 Plum majority. In ( b ), Orange wins the urban district while Plum wins the rural districts — the 2-1 result reflects the state-wide vote ratio. In ( c ), gerrymandering techniques ensure a 2-1 win to the state-wide minority Orange party.

# For a given orbit, the ratio of the cube of its semi-major axis to the square of its period is constant.

Jerrum, Valiant, and Vazirani showed that every # P-complete problem either has an FPRAS, or is essentially impossible to approximate ; if there is any polynomial-time algorithm which consistently produces an approximation of a # P-complete problem which is within a polynomial ratio in the size of the input of the exact answer, then that algorithm can be used to construct an FPRAS.

# The ratio of the channel noise at any point in a transmission system to an arbitrary level chosen as a reference.

# In asynchronous data transmission, the ratio of ( a ) the absolute value of the maximum measured difference between the actual and theoretical intervals separating any significant instant of modulation ( or demodulation ) from the significant instant of the start element immediately preceding it to ( b ) the unit interval.

# The ratio of power gain between the front and rear of a directional antenna.

# At a discontinuity or impedance mismatch, e. g. in a transmission line, the ratio of the incident power to the reflected power.

# The ratio of ( a ) total received power, i. e., the signal to ( b ) the noise-plus-distortion power.

# The ratio of ( a ) the power of original modulating audio signal, i. e., from a modulated radio frequency carrier to ( b ) the residual audio power, i. e., noise-plus-distortion powers remaining after the original modulating audio signal is removed.
