Summary
Chinese facial aesthetics favor partially or mostly exposed, horizontal medial canthi. Preferences vary by age, gender, and occupation, underscoring the importance of natural features.
Area of Science:
- Plastic Surgery
- Facial Aesthetics
- Ophthalmology
Background:
- Medial canthi are key to Chinese facial aesthetics and perceived eye shape.
- The aesthetic significance of medial canthic folds has been historically underestimated.
Purpose of the Study:
- To investigate aesthetic preferences for medial canthi in Chinese individuals.
- To identify demographic factors influencing these preferences.
Main Methods:
- An online survey of 352 Chinese participants was conducted.
- Participants rated images with varied medial canthi and eyelid morphologies.
- Multiple linear regression analyzed demographic influences (age, gender, occupation, etc.).
Main Results:
- A preference for partially/mostly exposed, horizontal medial canthi was observed.
- Gender, age, occupation, and cosmetic habits significantly influenced preferences.
- Specific preferences varied for different medial canthi exposures and eyelid types.
Conclusions:
- Aesthetic preferences for medial canthi are diverse across demographic groups.
- Partially/mostly exposed horizontal medial canthi are generally preferred.
- Preserving natural medial canthi characteristics is crucial in Chinese facial aesthetics.

01:27Steady Flow of a Fluid Stream
Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2.
During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

01:14Conservation of Mass in Moving, Nondeforming Control Volume
Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...

01:30Typical Model Studies
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.
01:21Design Example: Creating a Hydraulic Model of a Dam Spillway
Scaled hydraulic models of dam spillways provide a practical way to replicate and study the intricate flow dynamics of these structures. Often built to a 1:15 ratio, these models allow for observing critical water behavior, such as velocity distribution, flow patterns, and energy dissipation.
01:29Gradually Varying Flow
Gradually varying flow (GVF) in open channels describes situations where water depth changes slowly along the channel due to factors like non-uniform bed slope, channel shape variations, or obstructions. This flow type occurs when the depth adjusts gradually to balance gravitational forces, shear forces, and energy requirements, resulting in a low rate of depth change.Characteristics of Gradually Varying FlowGVF is commonly observed in natural streams, rivers, and canals, where flow depth...
01:24Rapidly Varying Flow
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...
