Generation Time01:22

Generation Time

1.5K
Bacterial generation time, the period required for a bacterial population to double during its exponential growth phase, serves as a critical measure of microbial growth dynamics under optimal conditions. This parameter varies significantly across bacterial species and can be influenced by factors such as temperature, pH, and the availability of nutrients. For example, Escherichia coli can achieve a generation time of approximately 20 minutes, while Mycobacterium tuberculosis exhibits a much...

Mixing Time01:19

Mixing Time

473
The concept of mixing time is significant in producing a uniform concrete mix with the required strength. The mixing period starts once all components are in the mixer. Initially, the mixer is charged with 10% of the water, followed by the consistent addition of solids and then 80% of the water. The remaining water is added later, within the first quarter of the mixing period. The minimum mixing time varies according to the mixer's capacity; for example, mixers with up to 1 cubic yard...

Mean free path and Mean free time01:22

Mean free path and Mean free time

5.1K
Consider the gas molecules in a cylinder. They move in a random motion as they collide with each other and change speed and direction. The average of all the path lengths between collisions is known as the "mean free path."

Time Course of Drug Effect01:14

Time Course of Drug Effect

2.7K
The progression of a drug's impact can be analyzed by examining both the concentration-time course and the effect-time course. The concentration-time course is determined by the drug's half-life and is influenced by factors such as its pharmacokinetics, including absorption, distribution, metabolism, and elimination. The effect of the drug is often related to its concentration in the plasma and is calculated using the maximum drug effect and the plasma concentration that generates 50...

Setting Time of Cement01:12

Setting Time of Cement

649
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

376
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Resumen

Nueva clasificación para oclusiones agudas de ictus en la arteria cerebral media

Área de la Ciencia:

  • Tratamiento neuroendovascular
  • Ictus isquémico agudo
  • Enfermedades cerebrovasculares

Sus antecedentes:

  • Existen datos limitados sobre oclusiones en las divisiones terminales de la arteria cerebral media y las ramas del surco lateral.
  • La práctica actual agrupa estas como lesiones del segmento M2, lo que dificulta el análisis específico.
  • Esta falta de datos granulares impide el progreso en la trombectomía transcatéter.

Objetivo del estudio:

  • Proponer una caracterización anatómica alternativa y clínicamente relevante para las oclusiones terminales de la arteria cerebral media.
  • Facilitar un informe más preciso de los resultados del tratamiento endovascular.
  • Abordar la brecha de conocimiento en el tratamiento de estas ubicaciones específicas de ictus.

Principales métodos:
