Muscles that Move the Arm01:31

Muscles that Move the Arm

4.8K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Components of Stress01:23

Components of Stress

542
Stress analysis under multiple loading conditions is intricate, necessitating a comprehensive grasp of normal and shearing stresses. Consider a small cube at point O, subjected to stress on all six faces, visible or not. Normal stress components σx, σy, σz act perpendicularly to the x, y, and z axes. Shearing stress components τxy and τxz are exerted on faces perpendicular to these axes.
Interestingly, the hidden cube faces also experience these stresses, equal and...

Components of Language01:24

Components of Language

821
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Intermolecular Forces03:13

Intermolecular Forces

71.4K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Electromotive Force02:36

Electromotive Force

30.2K
Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled  that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc  with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one substance to...

Intermolecular vs Intramolecular Forces03:00

Intermolecular vs Intramolecular Forces

97.3K
Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

    Summary

    Military personnel experienced 241 lightning strike injuries between 2008-2017. Rates were higher in males, younger adults, and those in combat roles, with most injuries occurring during summer months.

    Area of Science:

    • Environmental Health
    • Military Medicine
    • Injury Epidemiology

    Background:

    • Lightning strike injuries represent a significant environmental hazard, particularly for outdoor-active populations.
    • Understanding the epidemiology of lightning-related medical encounters in service members is crucial for targeted prevention strategies.

    Purpose of the Study:

    • To determine the incidence and characteristics of lightning strike injuries among U.S. service members from 2008 to 2017.
    • To identify demographic, occupational, and geographic risk factors associated with lightning strike injuries in this population.

    Main Methods:

    • Retrospective analysis of military health records using ICD-9 and ICD-10 codes for lightning-associated injuries.
    • Calculation of crude incidence rates per 100,000 person-years.
    • Comparison of injury rates across various demographic, occupational, and geographic subgroups.

    Main Results:

    • A total of 241 incident lightning-related medical encounters were identified.
    • The overall incidence rate was 1.9 cases per 100,000 person-years.
    • Higher incidence rates were observed in males, 20-29 year olds, non-Hispanic whites, Army members, enlisted personnel, those in combat occupations, and those stationed in the Southern U.S.
    • Most frequent diagnoses included "disturbance of skin sensation," headache, limb pain, and burns.
    • Peaks in incidence occurred in 2015, 2011, and 2013, with most injuries reported in June, July, August, and September.

    Conclusions:

    • Service members, especially those training or working outdoors during summer months, face a notable risk of lightning strike injuries.
    • Risk factors include male gender, younger age, specific occupations, and geographic location.
    • Vigilance and appropriate safety measures are essential for personnel operating in lightning-prone environments.
