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

475
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 Concrete01:26

Ready Mixed Concrete

354
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...

Design Example: Vintage Mixing Console

560
A sound engineer at a music company recently encountered a problem. The output from their newly acquired studio's vintage mixing console was too low for the requirements of modern recording equipment. To rectify this situation, the engineer decided to design an audio pre-amplifier using an operational amplifier (op-amp) to boost the signal level.
The specifications for the pre-amplifier were clear. It needed to amplify the audio signal by a factor of 10, have an input impedance above 10...

Adrenergic Agonists: Mixed-Action Agents01:28

Adrenergic Agonists: Mixed-Action Agents

1.4K
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

55.6K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Area of Science:

  • Surgical Navigation
  • Medical Imaging
  • Mixed Reality Technology

Background:

  • Intraoperative surgical navigation relies on integrating various data streams.
  • Current methods often require multiple monitors, potentially disrupting workflow.
  • Enhancing surgeon's situational awareness is crucial for complex laparoscopic procedures.

Purpose of the Study:

  • To design and validate a novel mixed reality head-mounted display (HMD) for intraoperative surgical navigation.
  • To evaluate the performance of the mixed reality navigation for laparoscopic surgery (MRNLS) system against conventional methods.
  • To assess the impact of MRNLS on task efficiency, user experience, and cognitive load.

Main Methods:

  • Development of a mixed reality navigation for laparoscopic surgery (MRNLS) system integrating laparoscope, navigation, and diagnostic imaging data.
  • Inclusion of immersive auditory feedback within the MRNLS system.
  • A comparative study involving 16 surgeons performing three surgical simulation tasks under two guidance conditions: laparoscopic navigation with CT guidance (LN-CT) and MRNLS.

Main Results:

  • MRNLS demonstrated significant improvements in task completion time and kinematics (mean velocity) for complex identification and transfer tasks compared to LN-CT (p < 0.05).
  • The system also led to significant reductions in mental demand and effort, as measured by the task load index.
  • For tasks involving sensitive structures, MRNLS significantly reduced completion time and user frustration.

Conclusions:

  • The novel mixed reality navigation for laparoscopic surgery (MRNLS) system has been successfully designed and validated.
  • MRNLS offers potential improvements in the ergonomics of laparoscopic surgery.
  • The system may reduce the need for additional monitors in the operating room, streamlining surgical workflow.
