A total of 850 insulation workers employed between 1940 and 1945 was identified from the personnel records of three large insula

tion manufacturing plants in the Midwestern U.S. in 1980. During the period 1940-1980, 28 deaths from lung cancer were discovered among the workers. Only eight lung cancer deaths, however, were reported among a comparable group of 800 coworkers who did not work with insulation during the same time period. The investigators had hypothesized that exposure to the insulation material increases the risk of lung cancer.

Answer:

The correct answer is - Retrospective Cohort

Explanation:

A Retrospective cohort study is a type of observational study or research. The investigator looks back in time self-report data to see if the risk of disease was different between exposed and non-exposed patients.

The distinguishing feature, that help in identifying it, of this study is that the investigators conceive the study and begin identifying subjects after results have already been found or developed in some of the subjects.

Strike441 [17]

The purpose of California’s law on seat belt use include:

  • To protect children from getting injured in a car accident.
  • To reduce the number of infant fatalities due to car accidents.
  • To enforce the need to exercise safety when driving with children.

<h3>What is Seat belt?</h3>

This is referred to as a safety device which protects the driver and passengers from harmful movement during a collision of two more vehicles.

When collision occurs, the force acts on the passengers and results in the movement of parts of the body which is why was enforced to ensure safety. It prevents the body from hitting other parts of the vehicle such as windscreen etc which could be fatal.

This is why it must be practiced at all time and helps reduce the number of fatalities encountered during an accident or sudden stop in vehicles.

The full question is.

A 23-year-old woman is using an albuterol inhaler for frequent acute episodes of asthma and complains of symptoms that she ascribes to the albuterol. Which of the following is not a recognized action of albuterol? (A)Diuretic effect

(B)Positive inotropic effect

(C)Skeletal muscle tremor

(D)Smooth muscle relaxation

(E)Tachycardia

The right option is A. Diuretic effect

Explanation:

Albuterol is a β2-selective receptor agonist, but in moderate to high doses it induces β1 cardiac effects as well as β2-mediated smooth and skeletal muscle effects. It does not cause diuresis. The answer is A.

ElenaW [278]

Answer:

As stated in Chapter 1, the translation of human energy requirements into recommended intakes of food and the assessment of how well the available food supplies or diets of populations (or even of individuals) satisfy these requirements require knowledge of the amounts of available energy in individual foods. Determining the energy content of foods depends on the following: 1) the components of food that provide energy (protein, fat, carbohydrate, alcohol, polyols, organic acids and novel compounds) should be determined by appropriate analytical methods; 2) the quantity of each individual component must be converted to food energy using a generally accepted factor that expresses the amount of available energy per unit of weight; and 3) the food energies of all components must be added together to represent the nutritional energy value of the food for humans. The energy conversion factors and the models currently used assume that each component of a food has an energy factor that is fixed and that does not vary according to the proportions of other components in the food or diet.

Explanation:

The unit of energy in the International System of Units (SI)[8] is the joule (J). A joule is the energy expended when 1 kg is moved 1 m by a force of 1 Newton. This is the accepted standard unit of energy used in human energetics and it should also be used for the expression of energy in foods. Because nutritionists and food scientists are concerned with large amounts of energy, they generally use kiloJoules (kJ = 103 J) or megaJoules (MJ = 106 J). For many decades, food energy has been expressed in calories, which is not a coherent unit of thermochemical energy. Despite the recommendation of more than 30 years ago to use only joules, many scientists, non-scientists and consumers still find it difficult to abandon the use of calories. This is evident in that both joules (kJ) and calories (kcal) are used side by side in most regulatory frameworks, e.g. Codex Alimentarius (1991). Thus, while the use of joules alone is recommended by international convention, values for food energy in the following sections are given in both joules and calories, with kilojoules given first and kilocalories second, within parenthesis and in a different font (Arial 9). In tables, values for kilocalories are given in italic type. The conversion factors for joules and calories are: 1 kJ = 0.239 kcal; and 1 kcal = 4.184 kJ.
