Emission Spectra02:39

Emission Spectra

75.9K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Imaging Studies II: Positron Emission Tomography and Scintigraphy

535
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Mixing Concrete01:30

Mixing Concrete

373
Concrete mixing ensures a homogenous blend where aggregates are well-coated with cement paste. Concrete mixing is typically done using two main types of mixers: batch and continuous. Batch mixers handle one batch at a time, thoroughly combining materials before discharging and receiving the next batch. In contrast, continuous mixers receive a steady flow of ingredients, mixing them consistently and discharging without interruption. Within batch mixers, tilting drum mixers mix with internal...

Mixing Time01:19

Mixing Time

477
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...

Ready Mixed Concrete

356
Ready-mixed concrete, also known as pre-mixed concrete, is prepared in a centralized plant and then transported in trucks to construction sites where it is ready for placement. This type of concrete is categorized into central-mixed, truck-mixed (or transit-mixed), and shrink-mixed. Central-mixed concrete is entirely prepared at a plant and moved to the site in agitator trucks that rotate at a speed of 2 to 6 rpm. Truck-mixed concrete, on the other hand, has the ingredients batched at the plant...

Positron Emission Tomography01:29

Positron Emission Tomography

7.1K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Area of Science:

  • Public Health
  • Environmental Health
  • Respiratory Physiology

Background:

  • E-cigarette use, or vaping, has surged among adolescents and adults.
  • Vape tricks involve specific inhalation/exhalation patterns for visual effects, potentially differing from standard use.
  • The prevalence and health risks of vape tricks remain largely unknown.

Purpose of the Study:

  • To characterize physiological metrics (duration, heart rate, respiratory rate, tidal/minute volume, physical activity) during vape trick performance.
  • To quantify e-cigarette emissions during vape tricks for exposure modeling.
  • To assess the health risks associated with vape tricks compared to typical vaping.

Main Methods:

  • Recruitment of e-cigarette users with experience in vape tricks.
  • Two data collection sessions: 20-minute standard puffing and a vape tricks session (up to five tricks).
  • Data gathered via surveys, interviews, video, personal exposure monitors, and biometric garments.

Main Results:

  • Data analysis is pending; results were scheduled for Fall 2019.
  • No results are available at this time.

Conclusions:

  • The study assesses the feasibility of using biometric garments alongside environmental data.
  • This methodology may offer deeper insights into the health implications of performing vape tricks.
