Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...

Electrical Power

Electrical Power

Electric power is the product of current and voltage, represented in units of joules per second, or watts. For example, cars often have one or more auxiliary power outlets with which you can charge a cell phone or other electronic devices. These outlets may be rated at 20 amps and 12 volts, so that the circuit can deliver a maximum power of 240 watts. Consider a 25 Watt bulb and a 60 Watt bulb. The conversion of electrical energy produces heat and light, while the kinetic energy lost by the...

Average Power

Average Power

In practical electrical applications, the concept of time-varying instantaneous power is not frequently utilized. Instead, focus shifts to the more practical quantity known as average power. Average power is determined by integrating the instantaneous power over a specified time period and subsequently dividing it by that duration.

Power Factor Correction

Power Factor Correction

The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

Power System Distribution

Power System Distribution

Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.
The transmission system is designed...

Energy and Power Signals

Energy and Power Signals

In an electrical system with a resistor, voltage and current signals facilitate the measurement of power and energy across the resistor. For a continuous-time signal, the total energy over a time interval is defined as the integral of the square of the signal's magnitude over that interval. Mathematically, this is expressed as:

Area of Science:

Population genetics
Forensic science
Human genetics

Background:

Short tandem repeat (STR) loci are crucial markers in forensic genetics.
Accurate population-specific allele frequency data is essential for forensic DNA profiling.
Previous data may not fully represent the genetic diversity of the Argentinian population.

Purpose of the Study:

To estimate allele frequencies for 15 autosomal STR loci in the Argentinian population.
To assess the genetic diversity and population structure within Capital Federal and Buenos Aires Metropolitan Area.
To evaluate compliance with Hardy-Weinberg equilibrium (HWE) for forensic applications.

Main Methods:

Genotyping of 143 unrelated individuals using the PowerPlex 16 System.
Statistical analysis of allele frequencies for 15 autosomal STR loci.
Hardy-Weinberg equilibrium (HWE) testing.

Main Results:

Allele frequencies were successfully estimated for all 15 STR loci.
The population sample demonstrated adherence to Hardy-Weinberg equilibrium (HWE).
This dataset provides valuable genetic information for the specified Argentinian population.

Conclusions:

The estimated STR allele frequencies are suitable for forensic identification in Argentina.
The population's genetic profile is consistent with Hardy-Weinberg equilibrium (HWE).
This study contributes essential data for the PowerPlex 16 System in forensic casework.
