Variance01:15

Variance

13.0K
The deviations show how spread out the data are about the mean. A positive deviation occurs when the data value exceeds the mean, whereas a negative deviation occurs when the data value is less than the mean. If the deviations are added, the sum is always zero. So one cannot simply add the deviations to get the data spread. By squaring the deviations, the numbers are made positive; thus, their sum will also be positive.
The standard deviation measures the spread in the same units as the data....

Finishing Concrete01:18

Finishing Concrete

388
Concrete finishing starts immediately after the concrete has been placed and consolidated. The initial step, screeding, involves leveling the concrete surface by removing excess material to flush it with the formwork's top. Following this, bull float or darby are employed to smooth the surface further, effectively lower high spots, fill low areas, and ensure larger aggregate particles are embedded within the concrete. This preparation is critical before the appearance of bleed water, as its...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Torque01:10

Torque

23.2K
Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as when pressing the accelerator in a car, which causes the engine to apply additional torque on the drivetrain. Here, we define torque and provide a framework to create an equation to calculate torque for a rigid body with fixed-axis rotation.
Torque can be considered as the rotational counterpart to force. Since forces change the translational...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

ortho–para-Directing Deactivators: Halogens01:24

ortho–para-Directing Deactivators: Halogens

7.0K
Halogens are ortho–para directors. They are more electronegative than carbon. Therefore, as ring substituents, they can withdraw electrons through the inductive effect and deactivate the aromatic ring towards electrophilic substitution. Halogens also have an electron-donating resonance effect on the ring, which influences the orientation of the incoming electrophile. If an electrophile attacks at the ortho or the para position, the halogen donates electrons and stabilizes the intermediate...

    Summary
    This summary is machine-generated.

    Canadian dental students show positive attitudes towards teledentistry integration, but report limited knowledge and training needs. Further research can guide teledentistry implementation in dental curricula.

    Area of Science:

    • Oral Health
    • Dental Education
    • Health Informatics

    Background:

    • Teledentistry offers potential to enhance oral healthcare access and quality.
    • Limited integration of teledentistry in dental education and practice is observed.
    • Canadian literature lacks research on dental students' perspectives on teledentistry.

    Purpose of the Study:

    • To explore undergraduate dental students' perceptions and experiences with teledentistry.
    • To identify training needs for teledentistry implementation in Canadian dental schools.

    Main Methods:

    • Cross-sectional study conducted from October 2022 to July 2023.
    • Online, bilingual, self-administered questionnaire distributed to third and fourth-year dental students in 3 Canadian provinces.
    • Descriptive analyses to determine conditions for successful teledentistry curriculum integration.

    Main Results:

    • 43 students completed the survey; most were female, aged 25-29, and in their third year.
    • Nearly all respondents lacked awareness of teledentistry guidance during the COVID-19 pandemic.
    • A majority expressed positive perceptions of incorporating teledentistry into the curriculum (81%) and clerkships (86%).

    Conclusions:

    • This study is the first to assess Canadian undergraduate dental students' attitudes, experiences, and needs regarding teledentistry.
    • Students exhibit positive attitudes but possess limited teledentistry knowledge and experience.
    • Findings can inform decision-makers on integrating teledentistry into dental curricula, despite the study's limited provincial scope.
