Biodiversity and Human Values

17.1K
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Professional Values

10.8K
Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

Critical Values01:31

Critical Values

10.4K
A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance level) for a given population parameter. The critical value provides demarcation that separates the sample statistics that are likely to occur from the ones that are unlikely to occur based on the given probability distribution and the population parameter to be estimated. The critical value for normal distribution is obtained from the z...

z Scores and Unusual Values01:07

z Scores and Unusual Values

11.1K
The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
 This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Inertial Frames of Reference01:03

Inertial Frames of Reference

8.9K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference01:27

Non-inertial Frames of Reference

7.2K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...

Summary
This summary is machine-generated.

This study established normal respiratory function values for Sudanese adults and children. Ethnic background significantly impacts lung function, with Arab Sudanese exhibiting higher results than those of African ethnicity.

Area of Science:

  • Pulmonary Medicine
  • Clinical Physiology
  • Public Health

Background:

  • Establishing normative data for respiratory function is crucial for accurate diagnosis and management.
  • Previous studies on Sudanese lung function are limited, necessitating updated reference values.

Purpose of the Study:

  • To determine normal reference values for respiratory function in a healthy Sudanese population.
  • To investigate the influence of ethnicity, age, and gender on lung function parameters.

Main Methods:

  • A randomized stratified cross-sectional study involving 2250 healthy Sudanese individuals aged 7-86 years.
  • Data collection included questionnaires, pulmonary function testing (spirometry), and anthropometric measurements.
  • Statistical analysis involved correlation and regression to establish relationships between variables.

Main Results:

  • Significant differences in forced vital capacity (FVC), forced expiratory volume in 1 second (FEVI), and peak expiratory flow rate (PEFR) were observed between Arab and African Sudanese ethnicities.
  • In adults, lung function showed a positive correlation with height and a negative correlation with age.
  • Confirmed variations in lung function based on gender and ethnicity.

Conclusions:

  • Ethnic background is a significant determinant of respiratory function in Sudan.
  • The derived regression equations and reference values can aid clinicians in interpreting pulmonary function tests.
  • This study provides essential data for respiratory healthcare in Sudan.
