The Periodic Table03:25

The Periodic Table

109.9K
As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...

Periodic Classification of the Elements

58.8K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Range

13.9K
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

Variation: Normal Distribution, Range, and Standard Deviation

27.0K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Effective Value of a Periodic Waveform01:07

Effective Value of a Periodic Waveform

1.2K
The concept of effective value, the root mean square (RMS) value, is crucial in understanding electrical circuits and power delivery. This idea emerges from the necessity to measure the effectiveness of a voltage or current source in supplying power to a resistive load.
The effective value of a periodic current represents the direct current (DC) that conveys the same average power to a resistor as the periodic current itself. This concept is crucial when assessing AC circuits. To determine the...

Area of Science:

  • Neonatal Medicine
  • Hematology
  • Clinical Pathology

Background:

  • Acquired coagulation disorders are a frequent cause of bleeding in newborns.
  • The thromboelastograph (TEG) is a valuable tool for assessing hemostasis.
  • Establishing neonatal-specific TEG reference ranges is essential for accurate diagnosis and management.

Purpose of the Study:

  • To determine the reference range for thromboelastograph (TEG) parameters in the neonatal period.
  • To provide a baseline for interpreting TEG results in infants.

Main Methods:

  • A study involving 371 full-term infants (≥37 weeks gestation).
  • Infants were categorized into three age groups: 1 day, 2-7 days, and 8-28 days.
  • Peripheral blood samples were analyzed using TEG, routine coagulation tests, and platelet counts.

Main Results:

  • Reference ranges (2.5th-97.5th percentiles) were established for TEG parameters: R (4.80s), Angle (69.90°), K (1.40min), MA (63.50mm), and LY30 (0.10%).
  • Significant differences in Angle, K, MA, and LY30 values were observed across the different neonatal age groups.
  • Correlations were found between standard laboratory coagulation tests and TEG parameters in neonates.

Conclusions:

  • This study provides preliminary reference ranges for TEG parameters in neonates.
  • Neonatal age significantly influences TEG parameter values.
  • The established reference values are vital for future research and clinical application in neonatal hemostasis.
