La biomecánica es la biomecánica.
Ciencia de los materiales Ciencia de los materiales.

Sus antecedentes:

Las municiones menos letales se utilizan con frecuencia para el control de multitudes.
Los impactos de estos proyectiles pueden causar lesiones graves en la cabeza.
La distinción entre los tipos de proyectil (bolsa de frijoles frente a las rondas de espuma) es crucial para las investigaciones forenses.

Objetivo del estudio:

Para determinar si los patrones de defectos en la piel sintética pueden diferenciar las rondas de beanbag de las rondas de espuma.
Desarrollar un método rentable para el análisis forense de lesiones de proyectil menos letales.

Principales métodos:

Se dispararon proyectiles menos letales (cartuchos de bolsa de frijoles y de espuma) contra blancos de piel sintética.
Se analizaron los patrones de defectos de impacto para distinguir las características.

Principales resultados:

La piel sintética capturó efectivamente las características diferenciadoras de los impactos de los proyectiles.
Las principales características distintivas incluyeron el tamaño del defecto, la profundidad de penetración, la probabilidad de laceración y punteado.
Las rondas de bolsa de frijoles y las rondas de espuma produjeron patrones de defectos únicos.

Conclusiones:

La piel sintética es un sustrato viable para diferenciar las heridas del cuero cabelludo causadas por las rondas de beanbag y espuma.
El análisis de los patrones de defectos puede ayudar a las investigaciones forenses en lesiones de proyectil menos letales.

Projectile Motion: Example

Projectile Motion: Example

The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw their javelin in such a way that it travels as far as possible. The javelin thrower takes a short run-up to increase the initial speed of the javelin. The range of a projectile is at its maximum at a 45° angle so javelin throwers try to angle their throw as close to 45° as possible.
When we speak of the range (R) of a projectile on...

Motion of a Projectile

Motion of a Projectile

Projectile motion becomes evident when a player kicks the ball into the air. The launch angle, or the angle at which the ball is kicked, plays a crucial role in determining the trajectory of the projectile. As the ball soars through the air, influenced solely by gravity, its motion can be dissected into two independent velocity components: the horizontal and the vertical.
Horizontal motion, governed by the initial kick, maintains a constant velocity throughout the flight of the soccer ball.

Projectile Motion

Projectile Motion

An object thrown in the air follows a parabolic path under the influence of Earth's gravitational force. The motion of such an object is called projectile motion, and the object itself a projectile. The parabolic path followed by the projectile is called the trajectory. Some common examples of projectile motion are the launching of fireworks, a golf ball in the air, meteors entering the Earth's atmosphere, and the firing of bullets.
When an object falls under gravity and has no...

Projectile Motion: Equations

Projectile Motion: Equations

Projectile motion is commonly observed in our day-to-day life. For example, a basketball thrown by a player, an arrow shot from a bow, and kids jumping into the pool, all undergo projectile motion.
Any projectile motion problem can be solved by using the following strategy:

Lethal Alleles

Lethal Alleles

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Synthetic Biology

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.
